STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable.

BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure

The disclosure is directed to the delivery of items onto one or more target surfaces including elevated surfaces.

2. Background Art

In many working conditions, various items must be transported to one or more locations such as elevated surface locations requiring the assistance of conveyors and/or lifts in addition to manual labor in order to place items at one or more desired locations. For example, at loading docks various items are lifted to a platform of a ship or other vessel. In construction type operations, building materials and other items are delivered to construction floors via lift equipment or elevators. In home construction type operations, building materials and other items are typically delivered to rooftops and decks via manual labor or in combination with lift equipment or a conveyor lift. For example, bundles of shingles are typically transported to a house or other structure on pallets and either manually placed atop the rooftop of the house or other structure by hand or the bundles of shingles are lifted to the rooftop via lift equipment or a conveyor lift where persons manually place or set the bundle shingles at one or more desired locations along the rooftop. Such operations often take place on rooftops having sloping surfaces requiring the shingle bundles to be manually placed atop a rooftop in a secure manner in an attempt to keep the shingle bundles from sliding of the rooftop. Such operations also often take place at elevations requiring persons to wear safety equipment such as safety belts or safety harnesses to protect against slips and falls. In addition, many building materials are quite heavy exposing persons to bodily injury as a result of physically handling the building materials. Not only are persons subject to physical harm during such operations, but it can also be quite time consuming for personnel to get to an elevated location and/or tie down their safety equipment prior to manually moving any building materials.

Overcoming the above shortcomings is desired.

In yet another embodiment, a third linear actuator 56 may be provided as a mechanical actuator, e.g., a screw jack.

With particular reference to FIGS. 3-6, the distal end of the push assembly 52 includes a faceplate 58 with a forward facing pushing surface 59 operationally configured to engage one or more items located on a portable platform 200. As shown, two distal arms 60, 61 of the scissor linkage push assembly 52 are pivotally attached to a back side of the face plate 58 (see pivot point 63 in FIG. 6). In this embodiment, the forward pushing surface 59 is provided as a planar type surface disposed along a vertical plane having a width defining the width of the push assembly 52. In another embodiment, the forward pushing surface 59 may include a non-planar surface. The forward pushing surface 59 may also include a surface configuration for use with one or more particular target items to be carried by a portable platform 200. For example, the forward pushing surface 59 may include a curved surface defined by a radius for engaging cylindrical items of a certain outer diameter such as barrels, drums, buckets, and other cylindrical boxes and storage containers. The height of the forward pushing surface 59 may also vary as desired or as otherwise required for a particular operation of the apparatus 10.

In operation, the hydraulic cylinder 56 is operationally configured to direct the slide member 50 along the first horizontal attachment surface 21, which dictates the retraction and extension of the push assembly 52 according to its scissor linkage configuration. In particular, as the slide member 50 is directed toward the second frame section 20 the push assembly 52 is directed along a horizontal plane to an extended position as shown in FIGS. 3, 4 and 6. As the slide member 50 is directed away from the second frame section 20, the push assembly 52 is directed horizontally to a retracted position as shown in FIG. 5.

Referring now to FIG. 7, one suitable guide member 35 may include opposing side supports 68, 69 with a non-planar first guide surface 70 disposed there between at a first location and a non-planar second guide surface 75 disposed between the side supports 68, 69 at a second location and spaced apart from the first guide surface 70 defining an opening between the first guide surface 70 and the second guide surface 75 as shown. Suitably, the opening between the guide surfaces 70 and 75 is large enough to receive items of a unit load 300 there through (see directional arrow A). For example, in an embodiment where a unit load 300 includes stacked rows of bundles of shingles as illustrated in FIG. 7, the opening between the guide surfaces 70 and 75 is suitably large enough for each individual bundle of shingles of a unit load 300 to be directed through the opening between the guide surfaces 70 and 75 regardless of its lengthwise orientation as stacked on a portable platform 200. As such, one suitable opening between guide surfaces 70, 75 may include a width at least equal to or greater than the length of each individual bundle of shingles of a unit load 300. As understood by the skilled artisan, as of the time of this application a commercially available single bundle of shingles may be provided in packaging of various dimensions. One commercially available single bundle of shingles may be provided having dimensions as listed in Table 3.

Bundles of shingles are not limited to any particular commercial source. Exemplary commercial sources of bundles of shingles for use herein include, but are not necessarily limited to Owens Corning Intellectual Capital, LLC, Toledo, Ohio, U.S.A.; BMC Stock Holdings, Inc., Raleigh, North Carolina, U.S.A.; GAF Materials Corporation, Parsippany-Troy Hills, New Jersey, U.S.A.; CertainTeed Corporation, Valley Forge, Pennsylvania, U.S.A.; Atlas Roofing Corporation, Meridian, Mississippi, U.S.A.; TAMKO Building Products LLC, Galena, Kansas, U.S.A.; BP Canada Energy Group ULC, Calgary, Alberta, Canada; IKO Industries Ltd., Toronto, Ontario, Canada.

As shown in FIG. 7, each of the guide surfaces 70 and 75 may include a curved sliding surface to assist in directing items such as bundles of shingles of a unit load 300 (herein bundles of shingles may be referred to as “bundles of shingles 300”) there between. In another embodiment, one or more of the guide surfaces 70 and 75 may include multiple planar surfaces angularly aligned to operate cooperatively in a manner similar as a single or continuous curved surface configuration. In yet another embodiment, one or more of the guide surfaces 70 and 75 may include a different shape from that as shown in FIG. 7 for maximizing the passage of one or more particular items of unit load 300 through the guide surfaces 70 and 75, e.g., irregular shaped item(s) requiring guide surfaces 70 and 75 mirroring the shape of irregular shaped item(s).

Referring again to FIGS. 3 and 4, the third frame section 25 may be referred to as a leveling member or leveling assembly, wherein the third frame section 25 is (1) operationally configured as a connector to communicate the apparatus 10 with lifting equipment, e.g., a crane, hoist, wench, or other lifting device for moving the apparatus 10 in space as desired to one or more locations and (2) operationally configured to maintain the apparatus 10 in a vertical or substantially vertical alignment, i.e., maintain the second frame section 20 in a vertical or substantially vertical alignment with the earth's gravitational vector during operation of the apparatus 10 (herein referred to as “vertical alignment” of the apparatus 10). With reference to FIGS. 7 and 8, the third frame section 25 of the frame may be provided as a hollow or partially hollow member including one or more fourth linear actuators 80 housed therein. In one suitable embodiment, the third frame section 25 may include a double acting hydraulic cylinder as described above wherein the bore at a tail end of the hydraulic cylinder is secured to an inner surface of the third frame section 25 at attachment point 81 and the distal end of the drive rod is attached to a lift or hoist attachment member 84 at attachment point 82. As shown in FIG. 7, the third frame section 25 of this embodiment suitably includes an opening in the form of an elongated slot 87 operationally configured for the lift or hoist attachment member 84 (hereafter “lift attachment member 84”) to be directed linearly in either direction along the length of the slot 87 according to the stroke of the hydraulic cylinder 80 (see directional arrow C in FIG. 8). The length of the slot 87 is not limited but may vary as desired, which in turn may dictate the size and/or stroke of the hydraulic cylinder 80.

In this embodiment, the lift attachment member 84 is provided in the form of a lift eye operationally configured to partially extend out through the slot 87 providing an attachment surface for a lift line 5 or other lifting or hoisting attachment or assembly of lifting equipment, for example, a hook, clevis fastener, or other rigging equipment. The lift attachment member 84 is affixed to a slide member 88 that resides inside the third frame section 25 and slides along the inside of the third frame section 25. The slide member 88 is smaller than the inside of the third frame section 25 such that it can be fitted with wear protection devices such as wear pads and the like. In another embodiment, the lift attachment member 84 may be provided as a handle, hook, eye bolt, clevis fastener, or hydraulic rotating unit. Hydraulic rotating units as understood by the skilled artisan, can also be mounted to the lift attachment member 84 via a clevis fastener, hook, pin, bolts/fasteners and other rigging equipment. A hydraulic rotation device suitably allows a user to rotate the apparatus 10, and a unit load 300 carried by the apparatus 10, to a desired orientation according to a roof or other surface where a unit load 300 or part thereof is to be placed. In another embodiment, the third frame section 25 may itself operate as an attachment surface, for example, tying off the apparatus 10 via the third frame section 25 with rope, strapping, cable, chain, wire, and combinations thereof and/or hooking or latching the third frame section 25 with a hook or sling hook as known in the art of lifting equipment.

In operation, the hydraulic cylinder 80 located inside the third frame section 25 may be powered to change the location of the lift attachment member 84 along the length of the slot 87 thereby changing the center of gravity of the apparatus 10 to maintain a horizontal or substantially horizontal or level orientation of the apparatus 10 and any portable platform 200 and any unit load 300 carried by the apparatus 10 when the apparatus 10 is lifted to a suspended elevated position relative the ground or other floor type surface during transport. For example, in a scenario where the apparatus 10 is in a suspended elevated position or lifted position off the ground or other floor type surface with a lift attachment member 84 positioned as depicted in FIG. 9, if the apparatus 10 is leaning backward in an un-level position with the distal ends of the fork tines 12 and 13 pointing upward as depicted in FIG. 9, the hydraulic cylinder 80 may be powered to direct the lift attachment member 84 rearward (see directional arrow B in FIG. 7 and FIG. 9) directing the apparatus 10 to a level or substantially level position as shown in FIG. 10 (see directional arrow D) safe for transport of the portable platform 200 and unit load 300 carried by the apparatus 10. In this embodiment, (1) the angle of the third frame section 25 relative the second frame section 20, (2) the location of the lift attachment member 84 along the length of the third frame section 25 and (3) the position of the center of gravity of a unit load 300 in relation to the position of the center of gravity of the apparatus 10 dictate the orientation of the apparatus 10 in space during transport at any moment in time.

In an embodiment of the apparatus 10 provided with hydraulic cylinders as described above, the apparatus 10 may also include a hydraulic control valve 85 (see FIGS. 3 and 4) operationally configured to provide and regulate hydraulic power to each of the hydraulic cylinders 37, 45, 56, 80 of the apparatus 10. In an embodiment where the apparatus 10 is lifted by a lifting member 400 (see FIG. 18) including lifting equipment, e.g., a crane, hoist, and other lifting device, commercially available and equipped with one or more hydraulic supply lines, e.g., hydraulic hoses, the one or more hydraulic supply lines of the lifting member 400 may be fluidly communicated with the hydraulic control valve 85 whereby pressurized fluid may be conveyed to one or more of the hydraulic cylinders 37, 45, 56, 80 as desired during operation of the apparatus 10.

One suitable hydraulic control valve 85 may include one or more hydraulic fluid inlet ports or fluid connections for receiving one or more hydraulic fluid lines, e.g., a flexible hydraulic hose or combination of flexible hose and non-flexible hydraulic tubing, typically associated with an auxiliary function of a lifting member 400. For example, commercially available lifting members 400 such as hydraulic cranes are typically equipped with one or more auxiliary hydraulic systems including control circuitry, a main control valve, and hydraulic fluid lines fluidly communicating the main control valve with a hydraulic rotator unit hanging from or otherwise attached at a distal end of a boom of a crane type lifting member 400. A typical auxiliary hydraulic system includes a supply line, e.g., a pressure hose, conveying pressurized fluid to a hydraulic rotator unit and a return line, e.g., a pressure hose, for conveying the hydraulic fluid back to the main control valve of the lifting member 400. For purposes of the present disclosure, the supply line may be disconnected from the hydraulic rotator unit and connected, possibly with extension hoses, to an inlet or pressure port located on the hydraulic control valve 85. Likewise, the return line may be disconnected from the hydraulic rotator unit and connected to a return port of the hydraulic control valve 85 of the apparatus 10.

Suitably, the apparatus 10 includes individual hydraulic fluid lines (not shown) fluidly communicating the hydraulic control valve 85 with each of the hydraulic cylinders 37, 45, 56, 80. In one embodiment, the hydraulic control valve 85 may include individual fluid ports corresponding to each of the hydraulic cylinders 37, 45, 56, 80 wherein a first end of each hydraulic fluid line is fluidly connected to a particular fluid port of the hydraulic control valve 85 and a second end of each hydraulic fluid line is fluidly connected to a port on a particular hydraulic cylinder 37, 45, 56, or 80. Exemplary hydraulic fluid lines include, but are not necessarily limited to hydraulic hoses, hydraulic tubes, and combinations thereof.

In one suitable embodiment, each hydraulic fluid line may include first and second ends with connectors operationally configured to provide sealed fluid connections between the hydraulic fluid lines and the ports of the hydraulic control valve 85 and the hydraulic cylinders 37, 45, 56, 80. Suitable connectors include, but are not necessarily limited to thirty-seven degree flare fittings, O-ring straight thread fittings, pipe thread fittings, split flange fittings, crimps, clamps, or other connectors operationally configured for high pressure hydraulic and/or pneumatic use.

In one suitable embodiment of the apparatus 10, each of the hydraulic cylinders 37, 45, 56, 80 has a first connection port allowing pressurized fluid to be supplied to the rod side of each of the hydraulic cylinders 37, 45, 56, 80 and a second connection port allowing pressurized fluid to be supplied to the base side of each cylinder 37, 45, 56, 80. In particular, the hydraulic control valve 85 may be provided with independently operated circuits, known to the skilled artisan as “work sections.” Each work section may have two connection ports, commonly referred to by the skilled artisan as an “A” port and “B” port. In one embodiment of the hydraulic control valve 85, the “A” port is operationally configured to supply fluid to a hydraulic cylinder and the “B” port is operationally configured to provide a path for the return of hydraulic fluid from the hydraulic cylinder. The hydraulic control valve 85 may also be operationally configured to provide fluid pressure to the “B” port and return fluid flow via the “A” port. When not in use, the hydraulic control valve 85 may be configured or set to provide zero fluid flow to or from the “A” and “B” ports, commonly referred to by the skilled artisan as a “center position” or “neutral position” of the hydraulic control valve 85.

In the embodiment of FIGS. 3 and 4, the hydraulic control valve 85 has five work sections. The inlet, outlet, and work sections of the hydraulic control valve 85 may be configured for operation as follows:

- (1) Fluid Inlet of the hydraulic control valve 85: The supply line of the lifting member 400 is fluidly connected to a pressure port of the hydraulic control valve 85. The pressure port may include a pressure relief valve effective as a circuit protection feature of the hydraulic control valve 85. When circuit pressure exceeds the pressure relief setting of the pressure relief valve, the pressure relief valve suitably diverts pressure to the return line via the return port of the hydraulic control valve 85 preventing damage to the hydraulic control valve 85.
- (2) Work section 1: Port A (the “A” port) is connected to port A on the hydraulic rotator unit. Port B (the “B” port) is connected to port B on the hydraulic rotator unit.
- (3) Work section 2: Port A is connected to port A on the hydraulic cylinder 45 and Port B is connected to port B on the hydraulic cylinder 45 for controlling the slide member 30.
- (4) Work section 3: Port A is connected to port A on the hydraulic cylinder 80 and Port B is connected to port B on the hydraulic cylinder 80 for controlling the center of gravity adjustment of the apparatus 10.
- (5) Work section 4: Port A is connected to port A on the hydraulic cylinders 37 and Port B is connected to port B on the hydraulic cylinders 37 for controlling the position of the guide member 35.
- (6) Work section 5: Port A is connected to port A on the hydraulic cylinder 56 and Port B is connected to port B on the hydraulic cylinder 56 for controlling extension and retraction of the push assembly 52.
- (7) Outlet Section: A return line connected to the return port of the hydraulic control valve 85 provides a fluid return for conveying hydraulic fluid from the apparatus 10 back to a hydraulic tank or other container on the lifting member 400.
- (8) Actuation of the work sections: A spool inside the hydraulic control valve 85 suitably shifts by way of an electrical signal. The electrical signal originates from the lifting member 400 via remote control. Some lifting member 400 remote controls (e.g., Hiab XS Drive) may be operationally configured to control additional functions beyond just the lifting member 400 itself. In one embodiment, remote control of the lifting member 400 may be set to a secondary control mode, whereby an operator may use the lifting member 400 remote control to remotely control the apparatus 10. For example, a wireless signal may be sent from the lifting member 400 remote control (e.g., a transmitter) to a receiver located on the apparatus 10. The receiver (not shown) sends the received signals to a valve driver or valve control module, i.e., an electronic device that sends control signals to each work section of hydraulic control valve 85. In operation, the hydraulic control valve 85 receives an electrical signal and shifts the spool to deliver fluid pressure to the appropriate work port, which in turn translates to motion in the associated member of the apparatus 10.

In this embodiment, the hydraulic control valve 85 is located on a front side of the slide member 30. In another embodiment, the hydraulic control valve 85 may be located on the third frame section 25 apart from the slot 87 and lift attachment member 84. One suitable hydraulic control valve 85 may include an L90LS mobile valve commercially available from Parker Hannifin Corporation, Cleveland, Ohio, U.S.A. In an embodiment of the apparatus 10 employing pneumatic air cylinders, the control valve 85 may be provided as a pneumatic control valve.

Referring to FIGS. 11-16, a simplified illustration of the apparatus 10 described above carrying a unit load 300 comprising a stack of bundles of shingles to a roof 500 is provided. As shown in FIG. 11, at initial operation of the apparatus 10 the guide member 35 may be set at an upper position as shown with the hydraulic cylinders 37 set to a fully retracted position. Once the fork tines 12 and 13 of the apparatus 10 are mated with openings of a pallet 200 carrying a stack of bundles of shingles of a unit load 300—shown here including a stack of eight rows of stacked bundles of shingles—the hydraulic cylinders 37 may be powered to an extended position thereby lowering the arm members 33 and guide member 35 to an operable position (see directional arrow E in FIG. 12).

Prior to transport of the apparatus 10 or once an apparatus 10 has arrived at a target location for removing the bundles of shingles of a unit load 300, the hydraulic cylinder 45 may be powered to direct the slide member 30 along the second frame section 20 until the forward pushing surface 59 of the faceplate 58 is aligned adjacent an upper row 301 of the stacked bundles of shingles of a unit load 300. Once the apparatus 10 reaches a target location adjacent a roof for unloading the bundles of shingles, the hydraulic cylinder 56 maybe powered to extend the push assembly 52 from a retracted position as shown in FIGS. 11 and 12 to an extended position (see directional arrow F in FIG. 13).

With reference to FIGS. 12-17, as the push assembly 52 is directed to an extended position, the forward pushing surface 59 of the faceplate 58 contacts a proximal side 303 of the upper row 301 of bundles of shingles thereby directing or forcing the distal side 305 upper row 301 of bundles of shingles toward the guide member 35 where the first guide surface 70 redirects the upper row 301 of bundles of shingles toward the second guide surface 75 for exiting out through the bottom of the guide member 35 onto a roof 500 under gravity. Suitably, the shape and length of the first guide surface 70 is operationally configured for a controlled and/or continuous sliding motion of bundles of shingles 301 toward the second guide surface 75 under gravity (see directional arrow G in FIG. 14 and FIG. 17) whereby the bundles of shingles 301 contact the second guide surface 75 while the proximal side 303 of the bundles of shingles 301 is still located atop the remaining stack of bundles of shingles of the unit load 300 and still in contact with the forward pushing surface 59 of the faceplate 58. Similar as described above, the shape and length of the second guide surface 75 is operationally configured for a controlled and/or continuous transition of bundle of shingles from a unit load 300 to a target location on a roof 500 (or “rooftop 500”), e.g., see FIG. 18, or other surface by landing each bundle of shingles in an inverted or flipped orientation in a non-destructive and/or non-violent manner in regard to the outer packaging and shingles of the bundle of shingles, e.g., without tearing the outer packaging and/or without damaging individual shingles for their intended use. In particular, the configuration of the guide member 35 of this embodiment turns each row of bundles of shingles from an initial upright position on a pallet 200 to an inverted or upside down position on a roof 500 or other surface. As such, if a particular unit load 300 of bundles of shingles is to have a particular side contacting and/or facing a roof 500 or other surface (a “target side” of the bundles of shingles) once removed from the apparatus 10, the unit load 300 may be set atop a platform support 16, or in this embodiment atop a portable platform 200, with the target side of the bundles of shingles facing away from a target roof 500 or other surface whereby the guide member 35 is operationally configured to turn or flip the bundles of shingles of the unit load 300 over resulting in the target side of each bundle of shingles contacting and/or facing a roof 500 or other surface. As such, a guide member 35 as described in FIGS. 12-17 may be referred to as an inverting guide member 35, a turning guide member 35, and the like.

The apparatus 10 further includes a push assembly adjustment system operationally configured to adjust the location of pushing assembly 52 as desire. For example, once an upper row 301 of bundles of shingles is unloaded to a roof 500 or other surface, the hydraulic cylinder 56 may be powered to return the push assembly 52 to a fully retracted position (see directional arrow H in FIG. 15). Once the push assembly 52 is set at a fully retracted position, the hydraulic cylinder 45 may be powered to direct the slide member 30 along the second frame section 20 (see directional arrow I in FIG. 16) until the forward pushing surface 59 of the faceplate 58 is aligned adjacent the next resulting upper row 302 of the stacked bundles of shingles of a unit load 300. Once aligned with upper row 302 of bundles of shingles, the hydraulic cylinder 56 may be powered to extend the push assembly 52 to an extended position whereby the forward pushing surface 59 of the faceplate 58 contacts a near side of the upper row 302 of bundled shingles and directs the upper row 302 of bundled shingles off of the remaining unit load 300 via the first guide surface 70 and the second guide surface 75 of the guide member 35 under gravity as described above. The process is repeated until each of the rows of bundled shingles of a unit load 300 is removed from the pallet 200.

The slide member 30 may be aligned with the next resulting upper row 302 and each row thereafter by way of an operator in real time, e.g., manually or via a video system including one or more cameras mounted to the apparatus 10. Without limiting the invention, one suitable camera may include, but is not necessarily limited to an action camera as understood by persons of ordinary skill in the art. As of the time of this application, one non-limiting example of an action camera is commercially available from GoPro, Inc., San Mateo, California, U.S.A. A camera may be releasably secured to the apparatus 10 via one or more fasteners and/or magnetic connections.

In another embodiment, the apparatus 10 may include control circuitry whereby the slide member 30 may be programmed via the control circuitry to travel a programmed or controlled or operable distance according to a configuration and/or size of a particular unit load 300 or its rows of items. For example, in an embodiment of the apparatus 10 including a unit load 300 including bundles of shingles having the dimensions as described in Table 3 or Table 4, the adjustment system may be operationally configured to direct the slide member 30 toward the first frame section 15, which simultaneously directs the faceplate 58 and forward pushing surface 59 toward the fork tines 12, 13 an equal distance as the slide member 30 as necessary for alignment of the faceplate 58 with the next successive row or rows of bundled shingles 300. Without limiting the disclosure, the slide member 30 may include a mechanical, electrical, optical or other type of sensing device, or combinations thereof, operationally configured to detect when the slide member 30 and faceplate 58 have traveled along the second frame section 20 to an operable position whereby the forward pushing surface 59 may contact the near side of the upper row 302 of bundled shingles and direct the upper row 302 of bundled shingles off of the stacked bundles of shingles of a unit load 300 between first guide surface 70 and the second guide surface 75 of the guide member 35. In another embodiment, the forward pushing surface 59 may be positioned to contact two upper rows of bundled shingles to push off both rows of bundled shingles simultaneously.

In one embodiment, the apparatus 10 may include one or more sensors electronically communicated with a corresponding lifting member 400 whereby the lifting member 400 is operationally configured to provide an audible signal, a visible signal, or a combination of audible and visual signals to an operator of the apparatus 10. Suitable audible and visible signals, i.e., audible and visible alarms, may include those audible and visible signals as known in the art of heavy equipment and the like, for example, horns and/or sirens and/or lights located at one or more locations of a lifting member 400, e.g., in a cabin or cab, on a boom, on a carrier or other part of a lifting member 400.

In another embodiment, the apparatus 10 may include one or more sensors electronically communicated with an audible signal, one or more visible signals, or a combination thereof. In another embodiment, control circuitry of the apparatus 10 may be programmed to automatically shut-off according to one or more pre-programmed sensor feedback conditions.

In another embodiment, one or more sensors may be positioned as desired to sense when the forward pushing surface 59 of the faceplate 58 has reached a desired vertical position suitable to contact a predetermined number of rows of bundled shingles 300 to be directed off from the pallet 200, i.e., the “target rows”). The one or more sensors may have one or more predetermined operating positions that correspond to the target rows. In one suitable embodiment, a desired or programmed sensor feedback condition may trigger an audible signal, a visual signal, or other signal such as an electronic communication sent to a computer system, cloud system, smartphone, or a combination thereof. In operation, when the one or more sensors realize a desired feedback condition corresponding to the target rows, the sensing device may (1) send a signal to the control circuitry of the apparatus 10 to stop the motion of the slide member 30 and/or (2) trigger an audible signal, a visual signal, other signal, or combination thereof.

In one suitable embodiment of the apparatus 10 for use with a unit load 300 comprising bundles of shingles having the dimensions listed above, a forward pushing surface 59 in the form of a planar surface as shown in FIG. 3 may be provided with the minimum and maximum dimensions as shown in Table 5 effective for directing one or more rows of bundles of shingles of a unit load 300 through the guide member 35.

TABLE 5

Minimum Length:
93.98 cm
(37.0 inches);

Maximum Length:
127.0 cm
(50.0 inches);

Minimum Height:
10.16 cm
(4.0 inches);

Maximum Height:
121.92 cm
(48.0 inches)

In another embodiment, the forward pushing surface 59 may include two or more separate planar members rather than a single member. In still another embodiment, the forward pushing surface 59 may include one or more horizontal tines, spikes or points effective for directing items of a unit load 300 off from the apparatus 10 to one or more target locations.

As understood by persons of ordinary skill in the art of shingles, bundles of shingles may be stacked in rows of alternating arrangement wherein a first row of bundled shingles may be aligned lengthwise in one direction and a second row of bundled shingles may be aligned lengthwise ninety-degrees relative the bundled shingles of the first row. As shown in FIGS. 5-7, each row of bundled shingles may include multiple bundles of shingles aligned side by side, e.g., three bundles of shingles aligned lengthwise front to back, and have a single bundle of shingles aligned lengthwise left to right at the front of one row of bundled shingles and aligned lengthwise left to right at the back of an adjacent row of bundled shingles. Other stacked configurations of shingles are herein contemplated as is understood by a person of ordinary skill in the art of portable platforms and stackable unit loads 300, e.g., single stacked bundles of shingles in common alignment. Accordingly, it is further contemplated that the push assembly 52 may be directed a distance suitable for removing an entire row of bundles shingles from a unit load 300 according to its orientation and location in relation to the guide member 35 of the apparatus 10 carrying the unit load 300.

In one mode of operation, each successive row of bundles of shingles of a unit load 300 removed from the apparatus 10 may be set or otherwise placed adjacent the preceding row of bundled shingles as shown in the simplified illustration of FIG. 18—see rows 301-304 of bundles of shingles. In such embodiment, a lifting member 400 such as a crane or the like may reposition the apparatus 10 in space after each row of bundles of shingles is removed from the pallet 200 in a manner effective to unload each row 301-304 of bundles of shingles 300 as shown in FIG. 18. As further shown, an elongated stop member 600 such as a wood board or other elongated member, e.g., see FIGS. 47 and 48 illustrating a plastic elongated stop member 600 manufactured via an extrusion process or a mold process, may be fixed to a roof 500 via one or more fasteners and/or a portable support type member may be installed atop a roof 500 without the need of any fasteners providing for alignment of the rows 301-304 along the roof 500 during unloading of the bundles of shingles from a unit load 300 and acting as a stop preventing the bundles of shingles from sliding off of a roof 500 including a pitched roof 500 as shown in FIG. 18. Other configurations of elongated stop members are herein contemplated, e.g., systems including L-bracket type members operationally configured to hold wood board and/or planks for purposes of stopping bundles of shingles from sliding off a roof 500. As understood by persons of ordinary skill in the art in the roofing industry, fasteners used on roofs and other building and construction locations may include, but are not necessarily limited to nails, screws, staples, and combinations thereof.

In another embodiment, one or more items comprising a unit load 300 including, but not necessarily limited to rows of bundles of shingles, may be stacked on a roof 500 as shown in FIG. 19. In such embodiment, a lifting member 400 can reposition the apparatus 10 at a different location after each row or rows of bundles of shingles is removed from a pallet 200.

As stated above, the apparatus 10 may also include one or more replaceable wear pads and the like (not shown) positioned between the slide member 30 and the second frame section 20 to minimize or prevent wearing of the slide member 30 and the second frame section 20 as a result of use over time. Similar wear pads and the like may also be positioned between the first horizontal attachment surface 21 and the horizontal slide member 50. Suitable wear pads may include, but are not necessarily limited to wear pads comprising plastic, filled nylon plastic, steel, bronze, brass, composite, ultra-high molecular weight (“UHMW”) polyethylene, and combinations thereof. One exemplary wear pad is commercially available from Cope Plastics, Inc. Alton, Illinois, U.S.A., under the trademark Nylatron®. As understood by the skilled artisan, wear pads may also be custom manufactured by fabrication companies that machine wear pads from steel, aluminum, plastic, and other metals and non-metals as desired.

Another embodiment of an apparatus 10 of the present disclosure is provided in FIGS. 20-29. As shown, the apparatus 10 of this embodiment includes a frame 111, including a horizontal base section 115, an intermediate section including a first vertical section 117 and a second vertical section 118 located at opposite ends of the base section 115 and extending out from the base section 115 in parallel alignment.

In another embodiment, the fork tines 112 and 113 may be sized and spaced for operation with a particular portable platform 200 as described above. In operation, the one or more hydraulic cylinders housed within the vertical sections 117 and 118 may be powered to direct the adjustable attachment surface 116 and the fork tines 112, 113 along the vertical sections 117 and 118 according to the stroke of the hydraulic cylinder(s) and/or the length of the vertical slots 106 and 107.

The apparatus 10 of this embodiment also includes a mover assembly operationally configured to direct a unit load 300 or part of a unit load from a platform support 16 and/or a portable platform 200 carried by the apparatus 10. Similar as described above, the mover assembly of this embodiment of the apparatus 10 is operationally configured to remove a unit load 300 comprising one or more rows of stackable items from a portable platform 200 by removing each uppermost row of a unit load 300 from its stack (see FIG. 23) until each row of stacked items has been removed from the portable platform 200.

In this embodiment, the mover assembly includes a push assembly 152 operationally configured to be directed toward and apart from the vertical sections 117 and 118 along a horizontal plane. Similar as above, the push assembly 152 of this embodiment may include a horizontally aligned scissor linkage or lazy-tong configuration. The mover assembly may further include an actuation assembly including at least one linear actuator 139 in communication with the push assembly 152 for extending and retracting the push assembly 152. One suitable linear actuator 139 may include, but is not necessarily limited to a hydraulic cylinder, pneumatic cylinder, or a mechanical actuator, e.g., a screw jack, located between the vertical section 117 and 118 or other location. In one particular embodiment, the linear actuator 139 may include a double acting hydraulic cylinder with a bore at a tail end secured to a mounting surface or attachment surface 142 of the vertical section 118 via a fastener, e.g., a pivot pin, a shoulder bolt, machined pin, trunnion mount, and the like and a drive rod with a distal end attached to a first arm member 154 of the push assembly 152 via a fastener, e.g., a pivot pin, a shoulder bolt, machined pin, trunnion mount, and the like—see pivot point 141. As further shown in FIG. 22, the push assembly 152 also includes a second arm member 155 pivotally attached to the attachment surface 142 or the vertical section 118.

The push assembly 152 includes a faceplate 158 defined by a forward pushing surface 159 operationally configured to engage one or more items located on a portable platform 200. With reference to FIG. 20, the faceplate 158 may include opposing lip members 166 and 167 providing pivotal attachment points 168 and 169 for distal arms 160 and 161 of the scissor linkage push assembly 152. In this embodiment, the forward pushing surface 59 is provided as a planar type surface along a vertical plane having a width defining the width of the push assembly 152 similar as described above.

With particular reference to the simplified example of FIGS. 24-28, at initial operation of the apparatus 10 the guide assembly, i.e., the arm members 133 and guide member 135 is suitably set at an upright fixed position (see FIG. 24) via one or more hydraulic cylinders and/or pneumatic cylinders or otherwise secured to the frame 111 via, one or more locking pins, one or more load holding valves, one or more clips, one or more springs, one or more clamps, one or more hooks, one or more latches, rope, chain, one or more magnets, and combinations thereof as the fork tines 112 and 113 of the apparatus 10 are mated with openings of a pallet 200 carrying unit load 300—shown in FIG. 24 as a stack of eight rows of bundles of shingles. Once the fork tines 112 and 113 engage the pallet 200, the guide assembly may be set to an unlocked position (see directional arrow J in FIG. 25) wherein the frame 111, arm members 133 and the guide member 135 enclose the unit load 300 and the apparatus 10 may be transported to a target location for removal of the unit load 300 from the pallet 200. Prior to transport or once the apparatus 10 has arrived at a target location, the one or more hydraulic cylinders housed within the vertical sections 117 and 118 may be powered to adjust the location of the adjustable attachment surface 116 and fork tines 12, 13 in relation to the location of the push assembly 152 in order to align the upper row 301 of the stacked bundles of shingles with the forward pushing surface 159 of the faceplate 158. The hydraulic cylinder 139 may then be powered to direct the push assembly 152 to an extended position (see directional arrow K), which directs or forces the upper row 301 of the bundles of shingles toward the guide member 135 (see FIG. 26) where the upper row 301 of the bundles of shingles slides down the guide member 135 under gravity (see directional arrow L). In order to remove the next resulting upper row 302 of the bundles of shingles, the hydraulic cylinder 139 is suitably powered to direct the push assembly 152 to a fully retracted position apart from the remaining stack of the bundles of shingles (see directional arrow M in FIG. 27). Once fully retracted, the one or more hydraulic cylinders housed within the vertical sections 117 and 118 may be powered to adjust the location of the adjustable attachment surface 116 and fork tines 12 and 13 in relation to the location of the push assembly 152 in order to align the upper row 302 of the bundles of shingles with the forward pushing surface 159 of the faceplate 158 (see directional arrow N in FIG. 28). The apparatus 10 may be powered to remove the upper row 302 similar as upper row 301 and the process may be repeated until each row of the bundles of shingles is removed from the pallet 200.

In a scenario where the apparatus 10 is being used to unload bundles of shingles of a unit load 300 onto a pitched roof, the guide member 135 may be angularly aligned facing the roof 500 as shown in FIG. 29. In another embodiment, the guide member 135 may be angularly aligned or substantially aligned directionally according to the slope of roof 500, e.g., facing the apparatus 10 of FIG. 29 180.0 degrees in the opposite direction. If the slope of one or more target roofs 500 are known, an apparatus 10 may be provided with a guide member 135 having a planar second surface 138 that extends out from the one or more arm members 133 at a desired angle for optimum transfer of bundles of shingles onto one or more target roofs 500 and/or other target surfaces.

In another embodiment, an apparatus 10 may be provided similar in design and construction as the embodiment of FIG. 3 but include a guide member similar in design as guide member 135 (see guide member 235 in FIG. 30). In still another embodiment as shown in FIGS. 31-34, an apparatus 10 may be provided with a faceplate 258 having a primary forward pushing surface 77 and a secondary forward pushing surface 78 operationally configured to maximize surface area for contacting part or all of a unit load 300. In this embodiment, the mover assembly of the apparatus 10 includes a push assembly with one or more vertically aligned scissor linkage or lazy tong configuration members 252A and 252B aligned in parallel and attached to the faceplate 258 on opposite sides as shown. The faceplate 258 of this embodiment includes opposing lip members 266 and 267 providing pivotal attachment points for a distal arm of each scissor linkage members of the scissor linkage members 252A, 252B (see distal arm 260A and attachment point 268 in FIG. 34). Each lip member 266 and 267 includes an open linear slot 91, 92 there through providing a mating surface for each of the distal arms 261A and 261B of each scissor linkage member 252A, 252B. As shown, each distal arm 261A and 261B may be provided as an elongated planar type member with a mating pin or other appendage extending out from the surface of each distal arm 261A, 261B at or near its distal end perpendicular to the plane of the distal arm 261A or 261B in a manner effective to mate with slots 91 and 92 (see mating pin 94 in FIG. 34). Each mating pin may be directed within its corresponding slot up to the length of the slot according to the retracted or extended position of each scissor linkage member 252A, 252B (see the location of the mating pin 94 within the slot 91 with scissor linkage member 252A set at an extended position). Without limiting the disclosure, one suitable mating pin 94 may include a nut and bolt combination such as a hex bolt and hex nut combination to maintain the mated position of the pin within slot.

With further reference to FIG. 34, the mover assembly of this embodiment includes an actuation assembly in communication with an adjustable assembly. Similar as described above, the adjustable assembly includes a slide member 230 secured to a vertical member 220 in a manner effective for the slide member 230 to travel along the vertical member 220 a distance equal to or less than the length of the vertical member 220.

With reference to FIGS. 32 and 34, the actuation assembly includes linear actuators 95 and 96 operationally configured to extend and retract corresponding scissor linkage members 252A and 252B. In this embodiment, the linear actuators 95 and 96 may include double acting hydraulic cylinders including a bore at a tail end for attachment to a mounting surface or attachment surface 97 and 98 of the slide member 230 and a drive rod having a distal end pivotally attached to a first arm member 254A or 254B (see pivot point 99). Herein, the attachment between the distal end of the drive rod and the first arm members 254A and 254B may be referred to as a “first attachment point” or “first pivot point” of each of the first arm members 254A and 254B. Similar as described above, in another embodiment the linear actuators 95 and 96 may be provided as one or more pneumatic cylinders. In another embodiment, the linear actuators 95 and 96 may be provided as mechanical actuators, e.g., screw jacks.

The slide member 230 of this embodiment includes linear slots on opposite sides of the slide member 230 providing a mating surface for each of the second arm members 255A, 255B of each scissor linkage member 252A, 252B (see slot 89 in FIG. 34). Similar as described above, each of the second arm members 255A and 255B is provided as an elongated planar type member with a mating pin or other appendage extending out from the surface of each second arm member 255A and 255B at or near its distal end perpendicular to the plane of the distal arm 255A or 255B in a manner effective to mate with corresponding slots, e.g., slot 89. Each mating pin may be directed within its corresponding slot up to the length of the slot according to the retracted or extended position of each scissor linkage member 252A, 252B (see the location of the mating pin 90 within slot 89 with scissor linkage member 252A set at an extended position in FIG. 34).

As shown, each of the first arm members 254A and 254B of this embodiment is provided as a non-linear member with opposing planar surfaces providing a second attachment point or second pivot point of the first arm members 254A and 254B. In particular, the slide member 230 of this embodiment suitably includes a mounting surface or attachment surface for each of the first arm members 254A and 254B providing a second attachment point or second pivot point of each of the first arm members 254A and 254B at a bend of each first arm member (see attachment surface 171 and pivot point 173 in FIG. 34). A non-limiting bend angle range of each of the first arm members 254A and 254B is 30.0 to 60.0 degrees. Suitably, the attachment points of each of the first arm members 254A and 254B promotes extension and retraction of each scissor linkage member 252A, 252B according to the stroke of the hydraulic cylinders 95 and 96 in a manner effective to direct a unit load 300 or part of a unit load 300 from a platform support 16 or a portable platform 200 carried by the apparatus 10.

With reference to FIG. 35, in another embodiment of the apparatus 10 extension and retraction of the push assembly 52 may be controlled by one or more linear actuators 175 and 176 pivotally attached to the faceplate 58 as shown. Similar as described above, the one or more linear actuators may be provided as double acting hydraulic cylinders 175, 176 each having a bore at a tail end for pivotal attachment to the distal ends of the third and fourth horizontal attachment surfaces 23 and 24 and a drive rod having a distal end pivotally attached at opposing ends of the faceplate 58.

Another embodiment of an apparatus 10 of the present disclosure is provided in FIGS. 49-71. With attention to FIGS. 49-52, the apparatus 10 of this embodiment includes a frame 411 including at least an elongated horizontal base section (hereafter “first frame section 415”) defined by a longitudinal center line, an elongated vertical intermediate section (hereafter “second frame section 420”) defined by a longitudinal center line including a proximal end 432 attached to the first frame section 415 in a fixed position, and an upper section (hereafter “third frame section 425”) defined by a longitudinal center line extending out from a distal end 436 of the second frame section 420 in a fixed forward position of the apparatus 10. Similar as described above, from a front view of the apparatus 10 the first frame section 415 is disposed along an X-axis, the second frame section 420 is disposed along a Y-axis and the third frame section 425 is disposed along a Z-axis.

In one embodiment, the frame 411 may be provided as a one-piece construction. In another embodiment, the first frame section 415, the second frame section 420 and the third frame section 425 may be provided as independent members releasably assembled or permanently assembled. In one embodiment, the first frame section 415, the second frame section 420 and the third frame section 425 may be releasably secured together via fasteners such as nut/bolt type fasteners and/or other threaded fasteners. As shown in FIGS. 49-52, the first frame section 415, the second frame section 420 and the third frame section 425 may be secured together via welds providing a fixed frame of the apparatus 10. In this embodiment, the frame 411 may include one or more stiffener members such as gusset plates or the like operationally configured to reinforce the connections between the second frame section 420 and the first and third frame sections 415 and 425. For example, the apparatus 10 may include opposing stiffener members 426 and 427 and/or stiffener member 428, which are connected to the second frame section 420 and to the third frame section 425 and operationally configured to reinforce the welded connection between the second frame section 420 and the third frame section 425 and transfer loads from the third frame section 425 to second frame section 420. The apparatus 10 may also include opposing stiffener members 429 and 431 connected to the second frame section 420 and the first frame section 415 operationally configured to reinforce the welded connection between the second frame section 420 and the first frame section 415 and to transfer loads from the second frame section 420 to the first frame section 415.

As shown, the first frame section 415, the second frame section 420 and the third frame section 425 are provided as elongated four sided members. In another embodiment, one or more of the first frame section 415, the second frame section 420 and the third frame section 425 may be provided as cylindrical members or other multi-sided member, e.g., three-sided, hexagonal, and the like. Similar as described above, the apparatus 10 may include one or more support members in the form of a platform support 16 as described above or in the form of fork tines 412 and 413 attached to and extending out from opposing ends of the first frame section 15 in parallel or substantially parallel as described above. As shown in FIG. 51, each of the fork tines 412 and 413 may include an adjustable collar 417 and 418 similar as described above including apertures 404 and 405 for receiving a corresponding locking pin there through. As understood by the skilled artisan, the maximum width between the fork tines 412 and 413 is dictated according to the length of the first frame section 415. With reference to FIGS. 51 and 53, the first frame section 415 may also include fork tine keepers 419 releasably fastened to the distal ends of the first frame section 415 and operationally configured to prevent the fork tines 412, 413 from slipping off from the first frame section 415.

Similar as described above, in this embodiment the third frame section 425 extends out from an attachment point with the distal end 436 of the second frame section 420 forming an angle—shown in this embodiment as forming a ninety (90.0) degree angle with the second frame section 420. In another embodiment, the angle formed may be greater than or less than ninety degrees. In this embodiment, the distal end 436 of the second frame section 420 acts as a support surface or seat for the third frame section 425 wherein the surface configuration of the distal end 436 may establish the angle of the third frame section 425 in relation to the second frame section 420.

In this embodiment, the third frame section 425 is provided as part of a leveling assembly operationally configured as a connector to communicate the apparatus 10 with a lift line 5 for directing the apparatus 10 to one or more locations in a desired orientation. The leveling assembly is also operationally configured to maintain the second frame section 420 in a vertical or substantially vertical alignment with the earth's gravitational vector during operation. With reference to FIGS. 51, 53 and 54, in addition to the third frame section 425, the leveling assembly further includes a leveling arm member 434 pivotally attached to the third frame section 425 and one or more linear actuators 480 operationally configured to direct the leveling arm member 434 toward and away from the third frame section 425 according to directional arrow O. As shown, in one embodiment the third frame section 425 may be provided as a hollow or partially hollow member for receiving one or more linear actuators 480 therein. In addition, the distal end of the third frame section 425 includes a space or open area operationally configured to receive a proximal end of the leveling arm member 434 whereby the one or more linear actuators 480 are operationally configured to direct the leveling arm member 434 between a fully extended position as shown in FIG. 53 and a fully contracted position as shown in FIG. 54.

Suitably, the third frame section 425, the leveling arm member 434 and the one or more linear actuators 480 are operably connected via fasteners and corresponding apertures for receiving the apertures there through. In addition, the leveling arm member 434 is provided as a hollow member with a proximal end shaped to include linkage geometry operationally configured to rotate the leveling arm member 434 according to directional arrow O when the leveling arm member 434 is acted on by the one or more linear actuators 480. For example, as shown in FIG. 51, the distal end of the third frame section 425 includes opposing apertures 439 provided via mounting plates 440 secured to the third frame member 425, e.g., via welds and/or fasteners, the opposing apertures 439 corresponding to a first set of apertures 441 of the leveling arm member 434 for receiving a pivot pin 442 there through in a manner effective for the leveling arm member 434 to be directed according to directional arrow O. The leveling arm member 434 also includes a second set of apertures 443 for receiving a fastener such as pin 444 there through for securing the one or more linear actuators 480 to the leveling arm member 434—the pin 444 being secured during operation via a cotter pin or the like. In addition, the third frame member 425 also includes opposing apertures 445 provided via the opposing stiffener members 427 and 428 for receiving a fastener such as pin 446 there through in a manner effective to secure the one or more linear actuators 480 to the third frame member 425. In this embodiment, the one or more linear actuators 480 may include a double acting hydraulic cylinder as described above in which the bore at a tail end of the hydraulic cylinder is secured to the third frame section 425 at attachment point 481 via pin 446 and the distal end of the drive rod 483 of the hydraulic cylinder 480 is pivotally attached to the leveling arm member 434 at attachment point 482 via pin 444.

With further reference to FIG. 51, the leveling assembly further includes a lift attachment member or crane mount 448 pivotally attached to the third frame section 425 via a pin 449 and fastener 450, e.g. a bolt or the like, the crane mount 448 including a connection bracket 451 as shown operationally configured to be fastened, e.g., via bolts or the like, to a hydraulic rotation mechanism of a lifting member 400 such as a crane or the like providing for controlled rotation of the apparatus 10 as desired. In another embodiment, a different type of connection may be employed for use with different lifting equipment.

Turning to FIGS. 53-57, when the apparatus 10 is empty, i.e., when there is no unit load 300 on the one or more support members, e.g., platform support 16, fork tines 412 and 413, and the apparatus 10 is in a resting position, the leveling arm member 434 is suitably set at a fully contracted position (FIG. 55) with the drive rod 483 of the hydraulic cylinder 480 set at a fully extended position. As the apparatus 10 is lifted to a suspended position via a lift line 5, the leveling arm member 434 is directed apart from the third frame section 425 according to directional arrow P as shown in FIG. 56. This rotational movement of the leveling arm member 434 translates to linear movement of the drive rod 483 of the hydraulic cylinder 480 in a retracted direction. Linear movement of the drive rod in a retracted direction causes hydraulic fluid, e.g., oil, to pressurize within the hydraulic cylinder 480. As understood by the skilled artisan, a hydraulic relief valve may be positioned in line with a hydraulic fluid port of the hydraulic cylinder 480 that is operationally configured to trap the hydraulic fluid and allow the fluid pressure to build inside the hydraulic cylinder 480. As also understood by the skilled artisan, hydraulic fluid is not compressible, as such, the hydraulic fluid acts like a solid and the drive rod 483 of the hydraulic cylinder 480 cannot move in a retracted direction any further until the pressure within the hydraulic cylinder 480 builds high enough to open the corresponding hydraulic relief valve. Once the hydraulic relief valve opens, the hydraulic fluid exits a base part of the hydraulic cylinder 480 directing the drive rod in a retracted direction allowing the leveling arm member 434 to rotate until the apparatus 10 reaches a level position, e.g., the one or more support members are oriented in a horizontal or substantially horizontal position.

Once a level position of the apparatus 10 is realized, the hydraulic relief valve pressure setting is equal or substantially equal to the pressure within the hydraulic cylinder 480 whereby the hydraulic relief valve is directed to a closed position. When the apparatus 10 is carrying a unit load 300, e.g., a full pallet of bundles of shingles, a level position of the apparatus 10 is realized when the leveling arm member 434 is in a vertical position or near vertical position as shown in FIG. 57. In such an operation, as bundles of shingles are removed from the apparatus 10, the center of gravity of the apparatus 10 changes thereby directing the apparatus 10 to a non-level position. During removal of the bundles of shingles, i.e., during the unloading phase, an operator of the apparatus 10 may pressurize the hydraulic cylinder 480 via controls, e.g., a joystick, which directs the drive rod of the hydraulic cylinder 480 in an extended direction. In particular, as the volume of hydraulic fluid within the hydraulic cylinder 480 increases, i.e., as the fluid pressure within the hydraulic cylinder 480 increases, the drive rod is directed linearly in an extended direction and directs the leveling arm member 434 toward a contracted position as desired. As stated above, leveling of the apparatus 10 is operator controlled, however, if the apparatus 10 is directed beyond its level position, the natural effect of the fluid pressure in the hydraulic cylinder 480 and the setting of the hydraulic relief valve are operationally configured to take effect to suspend the apparatus 10 from the lift line 5 in a level orientation.

Similar as described above, the apparatus 10 of this embodiment includes an adjustable assembly and a guide assembly. For example, the apparatus 10 includes a slide member 430 secured to the second frame section 420 in a manner effective for the slide member 430 to travel along the second frame section 420 a distance equal to or less than the length of the second frame section 420. The apparatus 10 of this embodiment also includes first and second horizontal attachment surfaces 421, 422 and third and fourth horizontal attachment surfaces 423, 424 extending out perpendicular from the slide member 430 as shown. In addition, the guide assembly of this embodiment includes one or more arm members 433 and an adjustable non-planar guide member 435 releasably secured to the one or more arm members 433. In particular, the guide member 435 includes one or more adjustable male type mating arm members 437 corresponding with the one or more female type arm members 433. As shown in FIG. 58, the one or more arm members 433 and corresponding mating arm members 437 include a plurality of apertures 408 and 409 operationally configured to adjust the length of the guide member 435 in relation to the second frame section 420 via one or more removable set pins 407. Seeing that the apparatus 10 may be built to scale, the size and number of apertures 408, 409 and the spacing between apertures 408, 409 may vary as desired or as otherwise required for one or more particular unit loads 300. For purposes of a unit load 300 comprising bundles of shingles, the distal ends of the one or more arm members 433 and the corresponding one or more mating arm members 437 may include apertures 408, 409 spaced apart to accommodate a plurality of sizes of bundles of shingles and stacking arrangements—often referred to as how bundles of shingles are palletized when stacked on a pallet. As understood by persons of ordinary skill in the art of shingles, economy type shingles are often palletized with three bundles of shingles per row (see FIG. 59) and architectural bundles of shingles are often palletized with four bundles of shingles per row (see FIG. 31). Apertures 408 and 409 of this embodiment of the apparatus 10 may include spacing measurements as described in Example 2 below.

Referring to FIGS. 58-59, the guide member 435 of this embodiment includes a proximal side 455 with a cutout section providing an open space at a midpoint of the proximal side 455—see inner edges 460, 461 and 462 defining the size and shape of the cutout section. Suitably, the size and shape of the cutout section is effective for the guide member 435 to be set to an upright position or folded position as shown in FIGS. 61-62 when the guide member 435 is set to a retracted position of the mating arm members 437 within the one or more arm members 433. In particular, the cutout section provides an open space along proximal side 455 of the guide member 435 allowing the guide member 435 to be directed to an upright vertical position whereby the cutout section of the guide member 435 provides clearance for receiving the second frame section 420 therein, which allows the guide member 435 to be set at a vertical position, which reduces the space required to store the apparatus 10 during storage and/or transport. As shown in FIG. 62, in one suitable embodiment the proximal side 455 is aligned with the rear portion 457 of the second frame section 420 when a retracted guide member 435 is set to a vertical position. When the guide member 435 is set to an extended position thereby increasing the length of the guide member 435, the guide member 435 may be directed toward a vertical position (see directional arrow Q) until the inner most surface of the cutout section, e.g., edge 462, contacts or draws near to the front side of the leveling arm member 434 as shown in FIGS. 63 and 64. In an embodiment of the apparatus 10 operationally configured for use with bundles of shingles, a minimum distance between inner edges 460 and 461 may include 25.4 cm (10.0 inches).

Referring to FIG. 50, the guide member 435 of this embodiment includes opposing side supports 468, 469 with a non-planar first guide surface 470 disposed there between at a first location and a non-planar second guide surface 475 disposed between the side supports 468, 469 at a second location and spaced apart from the first guide surface 470 defining an opening between the first guide surface 470 and the second guide surface 475 as shown. Suitably, the opening between the guide surfaces 470 and 475 is large enough to receive items of a unit load 300 there through similar as described above. The guide member 435 of this embodiment may also include an extension member 465 (or “kick plate”) hingedly attached thereto and/or resiliently attached thereto (see hinge 459 in FIG. 60) and operationally configured as a third guide surface to extend the effective travel surface of the second guide surface 470. Suitably, the hinged connection of the extension member 465 also allows the extension member 465 to pivot about the guide member 435 to conform to various inclined surfaces including one or more roof pitches for ease of removing items from the apparatus 10 and to protect against damaging target surfaces upon contact with the extension member 465. In one embodiment, the extension member 465 may be directly hingedly attached to the guide member 435. As shown in FIG. 58, in another embodiment the extension member 465 may include one or more mounting plates 466 for hingedly attaching the extension member 465 to the guide member 435. The one or more mounting plates 466 also suitably act as stiffener members providing structural support for corresponding hinged connections and clearance for pivotal movement of the extension member 465. The extension member 465 may be comprised of one or more planar members, one or more non-planar members, and combinations thereof.

Referring to FIG. 58, each of the one or more arm members 433 includes a hinge plate assembly comprising a plate member 463 and a seat member 464 pivotally attached to the plate member 463 via a hinge pin (see pivot point 467). As shown, each seat member 464 includes a U-shape type configuration or the like operationally configured as a support surface for part of the first and second horizontal attachment surfaces 421 and 422 as shown. As understood by the skilled artisan, the shape of the seat member 464 may vary according to the outer shape of a corresponding first and second horizontal attachment surfaces 421 and 422. The one or more arm members 433 of this embodiment are provided in an L-shape configuration with proximal ends including pairs of mounting plates 476, 477 attached thereto, e.g., via welds, that are pivotally communicated to one or more linear actuators 478, 479, e.g., double acting hydraulic cylinders, via pin type fasteners 501, 502 disposed through apertures of each pair of mounting plates 476, 477 and the corresponding drive rods of the one or more linear actuators 478, 479. As shown, the third and fourth horizontal attachment surfaces 423, 424 include a pair of mount plates 503, 504 attached thereto, e.g., via welds, for securing the opposite ends of the one or more linear actuators 478, 479, e.g., securing the bores at the tail ends of each of the hydraulic cylinders via pin type fasteners 505, 506. Accordingly, linear movement of the drive rods of the one or more linear actuators 478, 479 acts on the one or more arm members 433 whereby the one or more arm members 433 may be pivoted to one or more positions about the first and second horizontal attachment surfaces 421 and 422 (see pivot point 467) from a horizontal position as shown in FIGS. 49 and 50 to a vertical position as shown in FIGS. 61 and 62.

As shown in FIG. 49, the apparatus of this embodiment includes a push assembly 552 including opposing horizontally oriented scissor linkages and a faceplate 558 including a primary forward pushing surface 577 and a secondary forward pushing surface 578 similar as discussed above. In this embodiment, a first arm member 508 of each scissor linkage is pivotally connected to each of the first and second horizontal attachment surfaces 421 and 422 via an attachment surface 509 or mounting plate, a pivot pin 510 and a pin boss 511 assembly (see FIGS. 66-68). A second arm member 515 of each scissor linkage is provided as a linkage assembly including one or more roller type members 516 maintained within a linear track or track type housing 518 attached to the slide member 430 via welds or fasteners (see FIGS. 67 and 68). As shown in FIGS. 69 and 70, a suitable linkage assembly includes a second arm member 515 with an aperture 519 located near its proximal end including a cylindrical member 525 mounted about the aperture 519 operationally configured to receive an assembly of bearings 520, rings 521, and an elongated pin 522 for holding roller type members 516 and 517 on either side of the second arm member 515 in a turnable manner. As shown, the second arm member 515 includes one or more additional apertures operationally configured for linking with another arm member. Such apertures may be provided with oil embedded sleeve bearings 526 or the like to promote extension and retraction of the push assembly 552.

With further reference to FIGS. 66-68, each first arm member 508 includes an L-shape configuration including a proximal end that extends out beyond its attachment point with the attachment surface 509 and pivotally connects to a corresponding linear actuator 530, 531 e.g., a double acting hydraulic cylinder, that are operationally configured to act on the first arm members 508 to extend and retract the push assembly 552. In particular, the proximal end of the first arm members 508 and a distal end of the drive rods are pivotally communicated via a pivot coupling 532 and corresponding pivot pin assembly 533 and the bore at a tail end of the linear actuators 530, 531 are connected to attachment surfaces, e.g., a mounting plates 535, 536, located on the housing 518 via a fastening pin or the like.

Referring to FIG. 58, linear movement of the slide member 430 along the second frame section 420 is accomplished via at least one linear actuator 537, e.g., a double acting hydraulic cylinder, including a bore at its tail end attached to the slide member 430 and a drive rod with a distal end attached to the first frame section 415. In particular, a bore at the tail end of the linear actuator 537 is secured to the slide member 430 via one or more attachment surfaces, e.g., a pair of mount plates 538 and a pin type fastener 539 and the distal end of the drive rod of the linear actuator 537 is secured to the first frame section 415 via one or more attachment surfaces, e.g., a pair of mount plates 540 and a pin type fastener 541. In one suitable embodiment, mount plates 538 are attached to the slide member via welds and mount plates 540 are attached to the first frame section via welds.

Turning to FIG. 66, the apparatus 10 further includes a hydraulic manifold 545 operationally configured to provide and regulate hydraulic power to each of the hydraulic cylinders 478, 479, 530, 531, 537 of the apparatus 10. As described above, one or more hydraulic supply lines of a lifting member 400 may be fluidly communicated with the hydraulic manifold 545 whereby pressurized fluid may be conveyed to one or more of the hydraulic cylinders 478, 479, 530, 531, 537 as desired during operation of the apparatus 10. As further shown, the hydraulic manifold 545 may include an electric solenoid 547 operationally configured to actuate the hydraulic manifold 545. As understood by the skilled artisan, as DC electrical current is applied, the solenoid 547 suitably shifts and opens a fluid flow passage within the hydraulic manifold 545 thereby directing pressurized hydraulic fluid to a desired hydraulic cylinder of the apparatus 10. Without limiting the disclosure, one suitable hydraulic manifold 545 may be secured to the third horizontal attachment surface 423.

With further reference to FIG. 66, the apparatus 10 also includes a hose mount 554 (also referred to herein as a “bulkhead plate”) releasably secured to the slide member 430 and operationally configured as a point of attachment between hydraulic hoses 555 fluidly communicated with the hydraulic manifold 545 and hydraulic hoses 556 fluidly communicated with the hydraulic cylinders 478, 479, 530, 531, 537 (see threaded hydraulic hose crimp fittings 558 operationally configured to fluidly interconnect hydraulic hoses 555 and 556). The apparatus 10 may also include a hose track member 550 operationally configured to hold one or more hydraulic hoses 556 in a secure manner free from damage, entanglement and undesired disconnect from corresponding hydraulic cylinders 478, 479, 530, 531, 537.

With further reference to FIG. 66, the apparatus 10 may also include a weather tight or weatherproof electrical enclosure 549 operationally configured to house electrical equipment, including, but not necessarily limited to electric control circuitry or controller, one or more radio receivers, relays, fuses, wire harnesses, batteries, and combinations thereof, as may be required for operation of the apparatus 10 and its various functions for operation as described herein. Without limiting the disclosure, one suitable electrical enclosure 549 may be secured to the fourth horizontal attachment surfaces 424.

As discussed above, the inner dimensions of the slide member 430 may be greater than the outer dimensions of the second frame section 420 providing spacing for one or more wear pads 560. As shown in FIG. 71, the inner surface 562 of the slide member 430 may include one or more frame members 564 attached, e.g., welded, to the inner surface 562 operationally configured to hold corresponding wear pads 560 therein in a fixed manner during apparatus 10 operation. In one embodiment, the one or more wear pads 560 may be secured to the one or more frame members 564 via a snap-fit type mating. In another embodiment, adhesive material may be used to secure the one or more wear pads 560 to the inner surface 562 of the slide member 430 when mated with corresponding frame members 564. In another embodiment, one or more wear pads 560 may be adhered to the inner surface 562 of the slide member 430 without frame members 564. Suitable wear pads 560 may be constructed from nylon, ultra-high molecular weight plastic, metal, polyethylene, high density polyethylene, and combinations thereof. Suitable frame members 564 may be constructed from one or more metals including, but not necessarily limited to steel, aluminum, titanium, tungsten, other metals having strength properties high enough to withstand forces transmitted through the wear pads 560, and combinations thereof, such that the one or more frame members 564 hold the wear pads 560 in a fixed position during linear travel of the slide member 430 along the second frame section 420.

It is further contemplated that the apparatus 10 of the present disclosure may carry other items other than portable platforms 200. For example, items housed within bags, sacks, pouches, caging, netting, and the like, may be secured to the apparatus 10 via ropes, cables, elastic cords, chains, straps, and combinations thereof as understood by the skilled artisan. Although the apparatus 10 is described above in relation to a lifting member 400 such as a crane, hoist, or other lifting device, in another embodiment, the apparatus 10 of this disclosure may be lifted and/or transported via a pulley system via manual operation. In another embodiment, the apparatus 10 may include a push assembly 752 operationally configured to remove a unit load 300 off from a side of the apparatus 10 as shown in the simplified illustration of FIG. 112. In this embodiment, the apparatus 10 includes a support member or support arm 760 for pivotal attachment of the push assembly 752. The apparatus 10 also includes one or more linear actuators 762, e.g., one or more double acting hydraulic cylinders, attached to the support arm 760 and communicated with the push assembly 752 via a sleeve 765 that may directed along the support arm 760 via the one or more linear actuators 762 in a manner effective to direct the push assembly 752 between an extended position as shown in FIG. 112 and a retracted position. In another embodiment of the apparatus 10, a push assembly may include a swing arm pivotally attached thereto that is operationally configured to be directed about its pivot point on the apparatus 10 in a manner effective to remove a unit load 300 from the apparatus 10.

The apparatus 10 of this disclosure may also be provided as part of a system for carrying one or more items to one or more target surfaces and placing one or more items carried by the apparatus 10 onto one or more target surfaces, the system including one or more portable supports installed onto one or more target surfaces in a manner effective to hold and maintain the one or more items removed from the apparatus 10 on the one or more target surfaces. As described above, items may be removed from the apparatus 10 and placed onto one or more target surfaces without the need to manually remove the one or more items from the apparatus 10. Likewise, one or more portable supports may be installed onto one or more target surfaces without any manual assistance of individuals being located on or near the one or more target surfaces. In one embodiment, one or more portable supports may be delivered to one or more target surfaces via an apparatus 10 or via a lift line 5 of the apparatus 10 or other lifting or hoisting attachment or assembly of lifting equipment without use of the apparatus 10. As such, the present disclosure provides a system and method for the automated installation of one or more portable supports onto one or more target surfaces and the automated carrying of one or more items to the one or more target surfaces, including elevated surfaces, and placing items carried by the apparatus 10 onto one or more of the target surfaces in a manner effective to be retained on the one or more target surfaces by the one or more portable supports without the presence of individuals on or near the one more target surfaces during the process.

In one embodiment including one or more target surfaces comprising one or more roofs 500 of one or more houses, buildings or other structures, items such as one or more building materials 1099 and/or other items may be removed from the apparatus 10 and placed onto the one or more roofs 500 without any individuals being located on the one or more roofs 500 during removal of one or more items from the apparatus 10—a roof 500 in this scenario may be referred to as a “person free roof 500.” One simplified illustration of a system for delivering one or more bundles of shingles 1099 to a person free roof 500 is shown in FIG. 72. In this embodiment, the system may include an apparatus 10 lifted by a lifting member 400 and one or more portable supports 1000 installed on the roof 500 and operationally configured to hold or retain the one or more bundles of shingles 1099 on the roof 500 for an extended period of time as desired. In one embodiment, the one or more supports 1000 may be delivered to one or more target surfaces and installed thereon via the apparatus 10. In another embodiment, the one or more supports 1000 may be delivered to one or more target surfaces and installed thereon via a lift line 5 of the apparatus 10 or other lifting or hoisting attachment or assembly of lifting equipment without use of the apparatus 10. In still another embodiment, the one or more supports 1000 may be delivered to one or more target surfaces and installed thereon manually as may be desired or otherwise required for one or more particular operations.

One embodiment of a portable support 1000 of this disclosure is depicted in FIG. 73. The portable support 1000 of this embodiment includes a main section 1015 and two opposing raised sections 1020 and 1025 defining a first end and a second end of the portable support 1000. In one implementation, the portable support 1000 may be constructed from one or more rigid materials operation configured to maintain a fixed orientation of the portable support 1000. As such, the portable support 1000 may be provided in a size and/or shape for installation onto one or more particular surfaces of particular sizes and/or surface shapes. For example, a portable support 1000 as shown in FIG. 73 may be provided with a planar or substantially planar main section 1015 for installation upon a planar or substantially planar target surface (see roof 500 in FIG. 74). In another embodiment, the main section 1015 may be defined by an angle for installation upon a target surface 1005 defined by a peak, e.g., a roof defined by a ridge as shown in FIG. 75. In another embodiment, the main section 1015 may include a curved shape for installation upon a curved target surface 1005 as shown in FIG. 76. Referring again to FIG. 73, a portable support 1000 constructed from one or more rigid materials may be provided as a single one-piece construction, or in the alternative, a portable support 1000 may be provided as an assembly of individual parts. For example, the two opposing raised sections 1020 and 1025 may be permanently or releasably secured to the main section 1015.

As shown in FIG. 77, in another embodiment of a portable support 1000 constructed from one or more rigid materials, the main section 1015 may include two parts connected by a hinge member 1030 operationally configured for installation on planar or substantially planar target surfaces and/or target surfaces defined by a peak (“peaked surfaces”)—depicted as roofs 500 in FIGS. 74 and 75.

For example, a portable support 1000 constructed from one or more flexible materials is suitably operationally configured for installation and operable use on irregular surfaces such as multiple humped target surfaces and non-uniform target surfaces—see roof 500 in FIG. 80, which includes different angled surfaces on either side of the peak of the roof 500.

Turning to FIG. 81, a portable support 1000 as shown in FIGS. 73-80 includes a main section 1015 defined by an upper surface(s) 1016 and a bottom surface(s) 1017. As shown in FIG. 82, the bottom surface 1017 is operationally configured to contact one or more target surfaces such as a roof 500 surface and the upper surface 1016 is operationally configured to receive and support one or more building materials and/or other items thereon including, but not necessarily limited to one or more bundles of shingles of a unit load 300. In this embodiment, each of the raised sections 1020, 1025 includes an inner surface 1021 and 1026 operationally configured to act as a stop type surface for holding one or more building materials 1099 and/or other items on pitched roofs 500 and other surfaces where one or more building materials 1099 and/or other items may be directed in a downward direction as a result of gravitational force exerted on the one or more building materials 1099 and/or other items.

In one embodiment, the bottom surface 1017 of the main section 1015 may be operationally configured to engage one or more target surfaces in a manner effective to maintain the position of the portable support 1000 on one or more target surfaces during operation of the portable support 1000. In an embodiment of a portable support 1000 constructed from one or more rigid materials, the bottom surface 1017 may include one or more adhesive materials and/or adhesive coated members operationally configured to maintain a portable support 1000 in a fixed position on one or more target surfaces. In another embodiment, the bottom surface 1017 may include one or more spikes or teeth type members extending out from the bottom surface 1017 in a manner effective to engage one or more target surfaces. In another embodiment, the bottom surface 1017 may include one or more non-slip materials defining the bottom surface 1017. In another embodiment, the bottom surface 1017 may include one or more fiber based materials operationally configured to engage one or more target surfaces. The upper surface 1016 may also include one or more non-slip materials or friction materials operationally configured to stop and/or slow the movement of one or more building materials 1099 and/or other items thereon in real time as one or more building materials 1099 are removed from the apparatus 10 onto the portable support 1000.

Herein, suitable rigid materials of construction of the main section 1015 and the raised sections 1020 and 1025 may include, but are not necessarily limited to materials resistant to chipping, cracking, excessive bending and reshaping as a result of ozone, weathering, heat, moisture, other outside mechanical and chemical influences, as well as physical impacts. Exemplary rigid materials of construction include, but are not necessarily limited to metals, plastics, rubbers, woods, filled composite materials, and combinations thereof. Suitable metals may include, but are not necessarily limited to stainless steel, hardened steel, mild steel, aluminum, copper, nickel, brass, and combinations thereof. Metals such as titanium are contemplated but may not be feasible based on material cost. Suitable plastics may include, but are not necessarily limited to acrylic or polymethyl methacrylate (“PMMA”), polycarbonate (“PC”), polyethylene (“PE”), polypropylene (“PP”), polyethylene terephthalate (“PETE”), polyvinyl chloride (“PVC”), acrylonitrile-butadiene-styrene (“ABS”), and combinations thereof. In an embodiment of the portable support 1000 including an assembly of individual parts, the raised sections 1020 and 1025 may be secured to the main section 1015 in a manner effective to operate as stop type members effective to hold one or more building materials 1099 and/or other items (see the resting position of the one or more building materials 1099 as shown in FIG. 82). In this type of embodiment, the raised sections 1020 and 1025 may also be referred to as stop members 1020 and 1025. In one embodiment, each of the stop members 1020 and 1025 may be releasably secured to the main section 1015 via one or more fasteners. In an embodiment including threaded fasteners such as threaded bolts, the main section 1015 may include apertures and the stop members 1020 and 1025 may include corresponding threaded holes for receiving threaded fasteners to secure the main section 1015 to the stop members 1020 and 1025.

In another embodiment, a portable support 1000 may be carried in a pouch type member (not shown) transported by a lifting member 400 and removed from the pouch type member or other carrier at an intended location on a target surface.

In another embodiment, one or more building materials 1099 and/or other items to be delivered to a target surface, e.g., a peaked roof 500, may be employed as stop members 1020, 1025. As an example, in an embodiment where the one or more building materials 1099 includes bundles of shingles 300 to be delivered to a roof 500, one or more bundles of shingles 300 may be used as stop members 1020, 1025 of a portable support 1000 and thereafter used as roofing shingles on the roof 500. In another embodiment, lumber and/or plastic planks and/or foam planks may be used as stop members 1020, 1025. Herein, such an embodiment of a portable support 1000 may also be referred to as a portable support system. As shown in FIG. 102, in one embodiment a portable support system may include a portable support 1000 with one or more sleeves 1065 whereby one or more building materials 1099, e.g., one or more bundles of shingles 300, and/or other items may be inserted into the sleeves 1065 and positioned for operable use as stop members 1020, 1025. In one embodiment, sleeves 1065 may include one open end and one closed end as shown in FIG. 102. In another embodiment, sleeves 1065 may include two open ends. As shown in FIG. 103, in another embodiment a portable support 1000 may include one or more pockets 1067 whereby one or more building materials 1099 and/or other items may be inserted into the one or more pockets 1067 for operable use as stop members 1020, 1025.

In another embodiment, straps 1069 or the like may be used to secure building materials 1099, e.g., one or more bundles of shingles 300, and/or other items for use as stop members 1020, 1025—see FIG. 100, which depicts straps 1069 for holding bundles of roofing shingles 300 in a manner effective as stop members 1020, 1025. Straps 1069 may include hook and loop fasteners, latches, hooks, buckles and other strap securing members effective to maintain the straps 1069 in an operating position for securing building materials 1099. Straps may also be maintained in an operation position via one or more adhesives, tape, stitching, staples, and combinations thereof.

In another embodiment, a portable support 1000 or portable support system may include one or more straps 1069, e.g., one or more flexible or bendable straps, as shown in FIG. 104. In this embodiment, a strap 1069 includes openings 1004 and 1006 located near opposing ends of the strap 1069 as shown. The strap 1069 may also include an opening 1009 at or near the midpoint of the strap 1069 as shown. In another embodiment, the strap 1069 may be provided without an opening 1009 at or near the midpoint of the strap 1069. In this embodiment, the openings 1004 and 1006 are not limited to a particular size and/or shape, however, overall size of the openings 1004 and 1006 may be dictated according to the length and width of the strap 1069. Suitably, the openings 1004 and 1006 include a size and shape operationally configured to receive part of the strap 1069 through the openings 1004 and 1006 in a manner effective to form one or more loops 1070, 1071 at one or more distal ends of the strap 1069 as shown in FIG. 105. In other words, the one or more loops 1070, 1071 may be formed by feeding part of the strap 1069 through its openings 1004 and 1006.

Depending on the material(s) of construction of the one or more straps 1069, the openings 1004, 1006 and 1009 may be formed during manufacturing of the one or more straps 1069, or users of the one or more straps 1069 may form the openings 1004, 1006 and 1009 in the one or more straps 1069 at the time of use or prior to use via a cutting instrument such as scissors, a knife, a razor blade, and the like. As understood by the skilled artisan, suitable strap material may be provided in bulk such as in rolls whereby persons can cut off one or more desired lengths of the strap material and form the openings 1004, 1006 and 1009 in the strap material to produce one or more straps 1069. Such straps 1069 may be produced and stored at a first location and used at a second location. In another embodiment, users of an apparatus 10 and lifting member 400 may transport strap material, e.g., one or more rolls of strap material, to one or target locations for the delivery of one or more building materials 1099 and/or other items and produce the one or more straps 1069 on location as desired or as otherwise required for workable installation of the portable support 1000 or portable support system on one or more target surfaces such as one or more roofs 500, e.g., calculate the length of the one or more straps 1069 to be produced according to the surface area and/or layout of the one or more target surfaces. In another embodiment, users of the apparatus 10 and the lifting member 400 may be provided guidelines as to the length of one or more straps 1069 prior to assembly of the portable support 1000 or portable support system. Depending on the material(s) of construction of the one or more straps 1069, the openings 1004, 1006 and 1009 may be reinforced for added strength to protecting against ripping or tearing of the one or more straps 1069 at the openings 1004, 1006 and 1009 by including tape and/or stitching along the perimeter of the openings 1004, 1006 and 1009 and/or by sealing the perimeter of the openings 1004, 1006 and 1009 via flame treatment as understood by the skilled artisan.

As understood by the skilled artisan, the size of each loop 1070, 1071 is dictated according to the length of the strap 1069 directed through each of the openings 1004 and 1006, e.g., loop 1070 is depicted larger than loop 1071 as the length of the strap 1069 directed through opening 1004 is greater than the length of the strap 1069 directed through opening 1006. The strap 1069 of this embodiment may be referred to as a “self-looping strap” because one or two loops 1070, 1071 may be formed in the strap 1069 as shown without having to tie knots in the strap 1069 to form and maintain the one or two loops 1070, 1071 and without having to use hook and loop fasteners, latches, hooks, buckles, one or more adhesives, tape, stitching, staples, or other strap securing members to form and maintain the one or two loops 1070, 1071. Examples of strap material for the one or more straps 1069 of this embodiment include, but are not necessarily limited to nylon webbing, polyester webbing, seatbelt webbing, and combinations thereof.

Once loops 1070 and 1071 are formed, one or more building materials 1099 and/or other items operationally configured as stop members 1020, 1025 may be set within the loops 1070 and 1071 of one or more straps 1069 and the one or more straps 1069 may be manipulated in a manner effective to tighten each loop 1070, 1071 around its corresponding one or more building materials 1099 and/or other items in a manner effective to hold or secure the one or more building materials 1099 and/or other items during installation of the portable support system, e.g., when carried by the apparatus 10 or other lifting member 400, and during operation of the portable support system. In one embodiment of a portable support system, the one or more building materials 1099 may include bundles of shingles 300 for use as stop members 1020, 1025 on a roof 500 (see FIG. 100). As shown in FIG. 100, one portable support system may comprise two straps 1069 aligned in parallel. In another embodiment, one or more rungs, e.g., strap material, may be employed to interconnect parallel straps 1069. In still another embodiment, a first strap 1069A may be inserted through an opening 1009 of a second strap 1069B interconnecting the first and second straps 1069A, 1069B providing an X-shape or cross-shape pair of straps 1069 for use as part of a portable support system as shown in the simplified illustration of FIG. 106. Although the strap 1069 of FIG. 104 is depicted in the form of a commercially available strap material, other shapes and/or configures of straps 1069 are herein contemplated.

Depending on the total number of bundles of shingles to be delivered to a target roof 500 and/or the size of the roof 500, one or more portable support systems may be installed on a common roof 500 as shown in FIG. 100. In operation, a desired number of individual bundles of shingles may be removed from a unit load 300 and connected to each of the loops 1070 and 1071 of one or more straps 1069 for use as stop members 1020, 1025 of a portable support system—see FIG. 100, which depicts stop members 1020, 1025 having a stack of two bundles of shingles oriented left to right parallel or substantially parallel to the ridge 1007 of a roof 500 as shown providing a maximum surface contact area of the bundles of shingles for stopping bundles of shingles removed from the apparatus 10 onto the roof 500. The total number of bundles of shingles used as stop members 1020, 1025 may include one or more bundles of shingles as desired or as may otherwise be required for a particular operation. In one embodiment, each stop member 1020, 1025 may include a total of three bundles of shingles in a stacked configuration. In another embodiment, each stop member 1020, 1025 may include a total of four bundles of shingles in a stacked configuration. Moreover, two or more portable support systems may be installed on a common roof 500 with at least one portable support system having stop members 1020, 1025 with a different total number of bundles of shingles compared to one or more other portable support systems installed on the same roof 500. In such embodiment, once bundles of shingles are removed from a unit load 300 to form stop members 1020, 1025 of a desired number of portable support systems, the apparatus 10 may carry and remove the remaining bundles of shingles for that particular unit load 300 onto the roof 500 in addition to one or more additional unit loads 300 as desired.

Similar as a portable support 1000 as described above, a portable support system may also be suspended from one or both fork tines 12 and 13 of an apparatus 10 or similar fork tines of a lifting member 400 and transported to a target surface, e.g., a roof 500, for purposes of installation as part of the automated shingle delivery and/or person free shingle delivery of this disclosure. In one non-limiting example as shown in FIG. 107, a portable support system 2000 may be suspended from the apparatus 10 during transport by resting a single stop member on the fork tines 12 and 13 of the apparatus 10 (see stop member 1025) with the opposing stop member being suspended below the fork tines 12 and 13 via one or more straps 1069. In another non-limiting example as shown in FIG. 108, a portable support system 2000 may be suspended from the apparatus 10 during transport by placing the one or more straps 1069 across the fork tines 12 and 13 of the apparatus 10 with both stop members 1020, 1025 suspending below the fork tines 12 and 13.

As shown in the simplified illustrations of FIGS. 109 and 110, a portable support system 2000 carried by an apparatus 10 in a manner as shown in FIG. 107 may be installed on a roof 500 by directing the front side 13A of the fork tines 12 and 13 toward a first surface 500A of a roof in a manner effective to set stop member 1020 on the first surface 500A at a desired installation location, i.e., a transverse direction in relation to the ridge 1007. Next, the apparatus 10 may be directed in a reverse direction according to directional arrow T whereby stop member 1025 may be directed off from the fork tines 12 and 13 onto a second surface 500B of the roof at a desired installation location according to directional arrow U. In another embodiment, the portable support system 200 may be installed in the opposite direction including placement of stop member 1020 on the second surface 500B and then placement of stop member 1025 on the first surface 500A.

As shown in the simplified illustration of FIG. 111, a portable support system 2000 carried by an apparatus 10 in a manner as shown in FIG. 108 may be installed on a roof 500 by approaching a ridge 1007 of a roof 500 longitudinally whereby the apparatus 10 may be lowered until the stop members 1020, 1025 are set on the roof 500. As shown, in this embodiment the distance between the stop members 1020, 1025 when suspended from the apparatus 10 is determined according to the outer width of the fork tines 12 and 13. As such, as the apparatus 10 is lowered, one or both stop members 1020, 1025 may be located on the roof 500 on either side of the ridge at a distance less than an installation distance between the 1020, 1025, i.e., one or both of the 1020, 1025 may be set on the roof 500 at a location(s) closer to the ridge 1007 than desired. Depending on the pitch of the roof 500, the stop members 1020, 1025 may slide to an installed position under gravity, i.e., slide away from the ridge 1007. Otherwise, the fork tines 12 and/or 13 may be used to direct one or both of the stop members 1020, 1025 to an installed position on the roof 500. In another embodiment, as bundles of shingles 300 are removed from the apparatus 10 onto the roof 500, momentum of one or more bundles of shingles 300 exiting the apparatus 10 may be used to push one or both of the stop members 1020, 1025 away from the ridge 1007 to an installed position.

In another embodiment of a portable support 1000, the stop members 1020 and 1025 may be operationally configured to support one or more building materials 1099 and/or other items on top of the stop members 1020 and 1025 separated apart from a target surface. In one non-limiting example as shown in FIG. 114 including a target surface comprising a ridge of a roof 500, the portable support 1000 is operationally configured to hold one or more building materials 1099 and/or other items at or near the peak of the roof 500 apart from the ridge 1007. In another embodiment it is contemplated that each stop member 1020 and 1025 may be located a different distance from a ridge 1007 of a roof 500 as may be desired or otherwise required for one or more particular operations.

The disclosure will be better understood with reference to the following non-limiting examples, which are illustrative only and not intended to limit the present disclosure to a particular embodiment.
