2. Description of the Related Art
Woodworking tools and other held-held or stationary power tools are commonly employed to grind, saw, polish, plane, or drill building materials for various construction, woodworking, or home improvement projects. These activities generate grindings, chips, and other solid particularities, such as saw dust and other debris throughout the various tools' operations. These particulates can create a safety hazard if not disposed of properly. For example, the residual wood chips and saw dust generated during a woodworking tool's operation can cause respiratory complications if inhaled by the operator. Furthermore, the debris can create the risk of a potential fire hazard if it is not properly collected and removed from the operator's work area.
In order to mitigate these risks, operators have attempted to use standard vacuum cleaners to collect the dust and other particulates. Standard vacuum cleaners, however, are typically incapable of filtering and collecting the debris and other large solid particulates generated by most woodworking tools. Because standard vacuum cleaners are not designed to handle such debris, their hoses and filters often become clogged or even damaged throughout the vacuuming process.
In order to overcome the drawbacks of standard vacuum cleaners, operators commonly employ large vacuum systems with specialized hoses and filters for retaining and collecting the particulates generated during the tools' operations. These vacuum systems employ larger hoses, stronger air pumps, and alternative filtering systems in order to prevent dust and debris from clogging or damaging the vacuum cleaner.
For example, U.S. Patent Publication No. 2004/0187449 to Witter describes a dust collection system for portable sanding or grinding equipment that employs a cyclone separator mounted directly on a woodworking tool or machine. During its operation, the dust is concentrated in the cyclone and a small volume air flow moves the dust through an elongated flexible hose or duct to a remote duct collection station. A cyclonic separator at the remote station separates the dust from the air flow and deposits it in a collection tank or drum.
U.S. Patent Publication No. 2004/0035092 to Wang describes a dust-collection device with a hollow cylindrical body positioned over a cart to collect debris in a dust collection bag. The device collection bag is configured to be quickly engaged and disengaged from the dust collection device for easy replacement.
U.S. Patent Publication No. 2005/0132679 to Tyburk describes a dust collection system and related airlock that includes a housing defining an interior chamber, an entrance hole and an exit hole, each hole being in fluid communication with the interior chamber. This configuration creates an airlock chamber to allow particulate material to enter and exit the airlock without the need for a collection bin being sealed to the dust collection system.
Although these prior art solutions can be effective for removing dust and debris during the operation of woodworking tools and the like, they create an inherent safety risk in their design. More specifically, collection devices such as the ones described in the foregoing examples must employ a high-powered vacuum pump in order to create the requisite suction to collect the debris. These pumps often comprise rapidly rotating blades that can pose a significant risk if an operator accidentally contacts the blades while coupling or decoupling the collection bags or vacuum hoses from the remaining elements of the vacuum device. Accordingly, the inventions disclosed and taught herein are directed to an apparatus and system for improving the safety of a vacuum device for collecting dust and debris that overcomes the problems set forth above.
The present invention is directed to an apparatus and system for improving the safety of a vacuum device. The apparatus and system employ multiple safety features to prohibit an operator from contacting the blades of the vacuum device during its operation.

The invention may be better understood by reference to one or more of these figures in combination with the detailed description of specific embodiments presented herein.
While the inventions disclosed herein are susceptible to various modifications and alternative forms, only a few specific embodiments have been shown by way of example in the drawings and are described in detail below. The figures and detailed descriptions of these specific embodiments are not intended to limit the breadth or scope of the inventive concepts or the appended claims in any manner. Rather, the figures and detailed written descriptions are provided to illustrate the inventive concepts to a person of ordinary skill in the art and to enable such person to make and use the inventive concepts.
The disclosure provides an apparatus and system for improving the safety of a vacuum device including a first intake cavity, a second intake cavity that can be coupled to a first housing, and a baffle disposed within the first intake cavity to limit the access to the blades of a vacuum pumping device. Alternatively, the apparatus can include a first intake cavity, a second intake cavity, and a baffle. The baffle can be adapted to channel solid particulates to a second intake cavity though a funneling motion. The apparatus can further include an external cover for limiting access to the blades of a vacuum pumping device. The system can include an intake interface, a first housing to receive a pumping device, a second housing device, and a collection unit. The system can further include an apparatus for limiting access to the blades of a vacuum pumping device.
Turning now to the figures,
At least a portion of the first tubular section 8 can include a first tapered section 12. The diameter of the first tapered section 12 can be smaller than the diameter of at least a portion of the first tubular section 8. The apparatus 2 can further include a tubular joint 16 that can couple the first tubular section 8 with the second tubular section 10. The tubular joint 16 can be adapted to be bent at an angle of approximately ninety degrees.
The first intake cavity 4 can include any cavity, slot, slit, opening, vent, void, or other recessed or hollow space capable of receiving any solid, liquid, gas, or gaseous-like material (depicted as a series of arrows in the figures). For example, the first intake cavity 4 can be configured to permit solid particulates to flow from a conduit 49 (as shown in
The second intake cavity 6 can include any cavity, slot, slit, opening, vent, void, or other recessed or hollow space capable of receiving any solid, liquid, gas, or gaseous-like material. For example, the second intake cavity 6 can be configured to permit solid particulates to flow from the first intake cavity 4 to a terminating edge of the second tubular section 10. In an exemplary and non-limiting illustrative embodiment, the second intake cavity 6 can be configured as a circular opening positioned at a terminating edge of the second tubular section 10. Alternatively, the second intake cavity 6 can be configured to be shaped as any other regularly or irregularly geometrically shaped opening capable of receiving solid, liquid, gas, or gaseous-like materials.
In an exemplary and non-limiting illustrative embodiment, the first tubular section 8 can have a uniform internal diameter and a non-uniform external diameter. For example, the first tubular section 8 can include a first tapered section 12 where at least a portion of the first tubular section 8 has an external diameter that is smaller than the exterior diameter of the remaining portions of the first tubular section 8. The internal diameter of the first tubular section 8 can be uniform throughout the entire length of the first tubular section 8. Alternatively, at least one portion of the internal diameter of the first tubular section 8 can be smaller than another portion of the first tubular section 8.
The term “diameter” as used herein and throughout the disclosure can refer to the greatest distance between two edges or corners of a cross-sectional area along a straight line. For example, if a cross-section of the first tubular section 8 is circular, the diameter is equal to twice the radius of the circle. If a cross-section of the first tubular section is rectangular, the diameter is the distance measured diagonally between two corners of the rectangular.
The first tapered section 12 can be employed as a means to couple the first tubular section 8 to another apparatus (not shown), for example, a vacuum hose, which in turn may be coupled to a vacuum apparatus or similar device, or to a vacuum tool to assist in debris pickup. The first tapered section's 12 smaller external diameter (as compared to the remaining portions of the first tubular section 8) can act as a groove to help secure the vacuum hose (not shown) in place when coupled to the apparatus 2. Alternatively, the first tapered section 12 can be replaced with at least one coupling element (not shown). The coupling element can include a tab, notch, slot, or any other means for coupling a vacuum attachment or any other apparatus to the first tubular section 8. For example, the first tapered section 12 can be replaced by a flexible tab capable of coupling a vacuum hose to, or decoupling a vacuum hose from, the first tubular section 8.
The first tubular section 8 can include any tube, pipe, hollow or partially hollow cylinder, duct, vent, or any other conduit capable of allowing the passage of a solid, liquid, gas, or gaseous-like material from a point of origin to a point of destination. In an exemplary and non-limiting illustrative embodiment, the first tubular section 8 can include at least a portion that is a hollow cylinder with a circular circumference. Alternatively, the first tubular section 8 can include a hollow conduit of other shapes and sizes. For example, the first tubular section 8 can include a conduit that includes a rectangular cross section for permitting material to flow from the first intake cavity 4 to the tubular joint 16.
The second tubular section 10 can include any tube, pipe, hollow or partially hollow cylinder, duct, vent, or any other conduit capable of allowing the passage of a solid, liquid, gas, or gaseous-like material from a point of origin to a point of destination. In an exemplary and non-limiting illustrative embodiment, the second tubular section 10 can include at least a portion that is a hollow cylinder with a circular circumference. Alternatively, the second tubular section 10 can include a hollow conduit of other shapes and sizes. For example, the second tubular section 10 can include a conduit that includes a rectangular cross section for permitting material to flow from the tubular joint 16 to the second intake cavity 6.
The slot 14 can include any slot, slit, notch, groove, aperture, or other narrow opening that can be adapted to adjust the orientation of the first intake cavity 6 with respect to the first housing 44 (as shown in
For example, the intake interface 42 (as shown in
The tubular joint 16 can include any attachment, coupling, fastener, link, or any other point of connection between the first tubular section 8 and the second tubular section 10. In an exemplary and non-limiting illustrative embodiment, the tubular joint 16 can be an elbow-shaped connector for disposing the first intake cavity 4 and the second intake cavity 6 at a ninety degree with respect to one another. Alternatively, the tubular joint 16 can include a connector for disposing the first intake cavity 4 and the second intake cavity 6 at any angle other than a ninety degree angle. In one embodiment, the tubular joint 16 can be omitted altogether. In this example, the first tubular section 8 and the second tubular section 10 can be disposed at 180-degree angles with respect to one another.
The tubular joint 16 can function as a conduit to permit material to flow from the first tubular section 8 to the second tubular section 10. The internal diameter of the tubular joint 16 can be the same as the internal diameter of both the first tubular section 8 and the second tubular section 10. Alternatively, the tubular joint can have an interior diameter that is different than one or more of the internal diameters of the first tubular section 8 and the second tubular section 10.
Although apparatus 2 is described throughout the disclosure as requiring at least a first intake cavity 4, a second intake cavity 6, a first tubular section 8, a second tubular element 10, and a tubular joint 16, other embodiments have been contemplated as well. For example, the first intake cavity 4 can include more than one first intake cavities 4 and more than one first tubular sections 8. In this example, the apparatus 2 can be embodied as a Y-shaped apparatus with two first intake cavities 4, and a single second intake cavity 6. Each of the first intake cavities 4 can include at least one baffle 18. Other configurations are contemplated as well. For example, the first intake cavity 4 can include more than one first intake cavity 4 and more than one first tubular section 8; the second intake cavity 6 can include more than one second intake cavity 6 and more than one second tubular section 10. This example, the apparatus 2 can be embodied as an X-shaped apparatus with two first intake cavities 4, and two second intake cavities 6.
The apparatus 2 can be made of injection-molded plastic, such as polypropylene, polyethylene, ABS, thermoplastics, polymerizing resin, polyacetal, polystyrene, and/or similar materials, with or without filling additives like fibers, chalks, or other flowable and settlable materials that may be injection-molded, cast, or low-pressure molded, in accordance with conventional practice.
The baffle 18 can include any type of wall, panel, divider, insert, rib, border, or the like capable of partially inhibiting or affecting the flow of material from the first intake cavity 4 to the first tubular section 8. The baffle 18 can be coupled to the first intake cavity 4, the first tubular section 8, or both. Alternatively, the baffle 18 can be formed as a single monolithic structure that can include the remaining components of the apparatus 2.
The baffle 18 can have a height 18h, a width 18w, and a length 18L. The width 18w can be measured as the distance from an edge of the baffle 18 nearest to the first intake cavity 4 to an edge of baffle 18 nearest to the tubular joint 16. The length 18L can be measured as the distance between two terminating edges of the baffle 18 that contact the inner portion of the first tubular section 8. The height 18h can be measured as the distance between the two sides of the baffle 18 with the greatest surface area (i.e., the thickness of the baffle 18).
In an exemplary and non-limiting illustrative embodiment, the baffle 18 can be disposed within the first intake cavity 4 such that is positioned in a substantially vertical configuration to minimize the amount of surface area the leading edge of the baffle 18 occupies within the cross sectional area of the first intake cavity 4. In this example, the only surface area of the baffle 18 that is exposed to the cross-sectional area of the first intake cavity 4 is the area of the baffle 18 measured by the height 18h and length 18L of the baffle 18. Additionally, the baffle 18 can be disposed within the first tubular section 8 such that fewer than two edges of the baffle 18 directly contact an inner portion of the first tubular section 8. For example the baffle 18 can be formed such that the length 18L can be shorter than the inner diameter of the first tubular section 8.
The baffle 18 can further include two or more baffles of various shapes and sized configured to prohibit an operator from accessing the second intake cavity 6 from the first intake cavity 4 while allowing material to flow between the first intake cavity 4 and second intake cavity 6. Sides of the baffle 18 can take the form of various geometric shapes including but not limited to squares, rectangles, trapezoids, rhombuses, circles, ellipses, and other regular or irregular geometric shapes.
The at least one flange 20 can be adapted to couple the apparatus 2 to the first housing 44 (as shown in
The system 40 can further include a collection unit 48 that can be adapted to collect solid particulates, dust, debris, or the like originating from the conduit 49. The collection unit 48 can include a first collection unit 48a and second collection unit 48b. The second collection unit 48b can be adapted to collect solid particulates originating from the conduit 49.
The first intake interface 42 can include any plate, guard, cover, lid, or the like for covering all or substantially all of the components of a pumping device (not shown). The pumping device can be adapted to be received by the first housing 44. The first intake interface 42 can be adapted to be coupled to, or decoupled from, the first housing 44. The first intake interface 42 can include a cavity (not shown) capable of permitting material to flow from the apparatus 2 to the second housing 46. The cavity can include one or more baffles (not shown) that can prohibit an operator from accessing the first housing 44 when the intake interface 42 is coupled to the first housing 44.
The first housing 44 can include any container, housing, repository, receptacle, or the like capable of housing a pumping device (not shown). The first housing 44 can be coupled to the intake interface 42, the apparatus 2, or both. The first housing 44 can further be coupled to the second housing 46. The pumping device (not shown) is capable of being disposed within the first housing 44.
The pumping device (not shown) can include a motor, pump, or any other device for raising, driving, or compressing air, gas, or other gaseous-like substances. The pumping device can further include one or more blades, propellers, fans, flabellums, or any other device capable of manipulating, regulating, or affecting the flow of air either inside or outside the first housing 44. The pumping device can be employed to create a partial vacuum in order to create suction to force materials, such as solid particularities, air, or other dust or debris, from the conduit 49 to the collector unit 48.
The second housing 46 can include any container, housing, repository, receptacle, or the like that can be adapted to separate material originating from the conduit 49. The second housing 46 can be coupled to the first housing 44, the collection unit 48, or both. The second housing 46 can separate material originating from the conduit 49 by channeling larger, solid particulates, such as saw dust, wood chips, debris, or the like to a first portion of the collection unit 48, while the remaining, smaller debris can be channeled to a second portion of the collection unit 48. Additionally, the second housing 46 can include a filter unit (not shown). The filter unit can include one or more High-Efficiency Particulate Air (HEPA) filters. Alternatively, the filter unit can be disposed within the collection unit 48.
The collection unit 48 can include a first collection unit 48a and a second collection unit 48b. The first collection unit 48a can be coupled to the second collection unit 48b so that first collection unit 48a is stacked vertically above the second collection unit 48b. Alternatively, the first collection unit 48a and the second collection unit 48b can be arranged horizontally. Furthermore, the first collection unit 48a and the second collection unit 48b can be arranged either in series, or in parallel, with respect to one another.
The collection unit 48 can be used as a repository for the storage of material collected originating from the conduit 49. The collection unit 48 can include one or more collection unit bags (not shown) for the removal of material stored in the collection unit 48. The one or more collection unit bags can be releasably coupled to, or decoupled from, the collection unit 48 so that the one or more collection unit bags can be detached and replaced if necessary.
Furthermore, the collection unit 48 can separate material originating from the conduit 49 by channeling larger, solid particulates, such as saw dust, wood chips, debris, or the like to second collection unit 48b, while the smaller debris remaining can be channeled to the first collection unit 48a. The collection unit 48 can channel the material into each of the respective collection units (48a and 48b) through the dual use of gravity and air pressure. That is, by channeling the material containing both solid particulates (such as saw dust, wood chips, debris, or the like) and smaller debris, the collection unit 48 can exploit the force of gravity to pull the larger debris into the second collection unit 48b, while the suction created by the pumping device (not shown) can force the smaller debris to the first collection unit 48a. Alternatively, the collection unit 48 can include more than two collection units.
The conduit 49 can include any hose, tube, pipe, channel, duct, or vent for allowing the passage of material in liquid, solid, gas, or gaseous-like form from one point of the system to another. For example, the conduit can be a vacuum cleaner hose that can be coupled to a vacuum device attachment (not shown). The conduit 49 can be made of a flexible, rigid, or partially rigid material. Additionally, the conduit 49 can be expandable such that its length can vary depending on the needs of an operator.
The apparatus 50 can include a first intake cavity 52 that can be adapted to be coupled to a conduit 49 (as shown in
The first intake cavity 52 can include any cavity, slot, slit, opening, vent, void, or other recessed or hollow space capable of receiving any solid, liquid, gas, or gaseous-like material (depicted as a series of arrows in the figures). For example, the first intake cavity 52 can be configured to permit solid particulates or other dust, debris, or the like to flow from a conduit 49 (as shown in
The second intake cavity 54 can include any cavity, slot, slit, opening, vent, void, or other recessed or hollow space capable of receiving any solid, liquid, gas, or gaseous-like material. For example, the second intake cavity 54 can be configured to permit solid particulates to flow from the first intake cavity 52 of the apparatus 50. In an exemplary and non-limiting illustrative embodiment, the second intake cavity 54 can be configured as a circular opening positioned at a terminating edge apparatus 50.
The baffle 56 can include any type of wall, panel, divider, insert, rib, border, or the like capable of channeling the flow of material from the first intake cavity 52 to the second intake cavity 54. In an exemplary and non-limiting illustrative embodiment, the baffle 56 can include a panel that partially forms an exterior portion of the apparatus 50. The baffle 56 can be formed as a single monolithic structure that includes the remaining components of the apparatus 50. Alternatively, the baffle 56 can be coupled to, and decoupled from, the remaining portions of the apparatus 50.
The baffle 56 can be adapted to channel solid particulates or other dust, debris, or the like in a partially cyclical fashion, such as in a spiral configuration. For example, the baffle 56 can be shaped in a spiral configuration to form a circle with a gradually decreasing diameter. When shaped in a spiral configuration, the baffle 56 can redirect, bend, curve, deviate, or divert the flow of solid particulates and other materials from the first intake cavity 52 to the second intake cavity 54 with an unrestricted flow. The baffle 56 can form a spiral configuration such that the first intake cavity 52 is located at the same height or at a height that is greater than that of the second intake cavity 54.
Furthermore, the baffle 56 can be adapted to channel solid particulates or other dust, debris, or the like by funneling the solid particulates or other debris from the first intake cavity 52 to the second intake cavity 54. This funneling can be accomplished by shaping the baffle 56 in a spiral configuration to form a circle with a diameter that decreases more rapidly than the partially cyclical fashion as described above. For example, the baffle 56 can be configured to funnel the solid particulates or other debris when the diameter of the circle defined by the spiral is less than 50% of the original diameter for every 360 degrees circumscribed. The baffle 56 can be configured in a partially cyclical fashion when the diameter of the circle defined by the spiral is between 50%-100% of the original diameter for every 360 degrees circumscribed.
The first coupling element 58 can include any screw, snap, hook, button, catch, clasp, bolt, clip, or any other fastener for coupling the external cover 59 to, or decoupling it from, the remaining components of the apparatus 50. The first coupling element 58 can include one or more coupling elements. Furthermore, the first coupling element 58 can be coupled to at least a portion of the baffle 56.
The external cover 59 can include a cover, panel, sheet, or any other divider capable of covering all or a substantial portion of the internal components of the apparatus 50. The external cover 59 can be formed as a solid, monolithic component in order to prohibit an operator from reaching the second intake cavity 54 while still allowing material to flow between the first intake cavity 52 and second intake cavity 54. By coupling the external cover 59 to the remaining components of apparatus 50, apparatus 50 can function as a safety device to prevent an operator from accessing any moving parts when coupled it is to other components of a vacuum system. Additionally, once the external cover 59 is coupled to the remaining components of the apparatus 50, the unique shape of the apparatus 50 can further prevent an operator from accessing any moving parts when it is coupled to other components of a vacuum system.
The apparatus 50 can further include an apparatus fastener (not shown). The apparatus fastener can include any screw, snap, hook, button, catch, clasp, bolt, clip, or any other fastener for securing the apparatus 50 to an intake interface 42 (as shown in
The apparatus 50 can be made of injection-molded plastic, such as polypropylene, polyethylene, ABS, thermoplastics, polymerizing resin, polyacetal, polystyrene, and/or similar materials, with or without filling additives like fibers, chalks, or other flowable and settlable materials that may be injection-molded, cast, or low-pressure molded, in accordance with conventional practice.
The second housing 46 includes a safety device 62 that can be adapted to limit the access from the second housing 46 to the first housing 44 (as shown in
The safety device 62 can include a tube, pipe, hollow or partially hollow cylinder, duct, vent, or any other conduit capable of allowing the passage of a solid, liquid, gas, or gaseous-like material from a point of origin to a point of destination. The safety device 62 can be shaped as a cube, rectangular prism, or any other regularly or irregularly-shaped geometric shape. The safety device 62 can further be coupled to the safety device flange 68.
The safety device flange 68 can include any guard, plug, bung, fitting, stopper, or other device that can prohibit an operator from contacting the first housing 44 (as showing in
The second coupling element 66 can include any screw, snap, hook, button, catch, clasp, bolt, clip, or any other fastener for coupling the safety device flange 68 to, or decoupling it from, the safety device 62. The second coupling element 66 can include one or more coupling elements. The at least one safety device baffle 69 can include one or more baffles that can extend orthogonally or substantially orthogonally from at least one plane of the safety device flange 68. The at least one safety device baffle 69 can include any type of wall, panel, divider, insert, rib, border, or the like capable of partially inhibiting or affecting the flow of material originating from a conduit 49 (as shown in
In an exemplary and non-limiting illustrative embodiment, the at least one safety device baffle 69 can be positioned in a vertical configuration to minimize the amount of surface area that the leading edge of the at least one safety device baffle 69 occupies within the cross-sectional area of the safety device 62. The at least one safety device baffle 69 can further include two or more baffles of various shapes and sizes configured to prohibit an operator from reaching through and accessing the collection unit interface 64 while allowing material to flow through the collection unit interface 64. Sides of the at least one baffle 69 can take the form of various geometric shapes including but not limited to squares, rectangles, trapezoids, rhombuses, circles, ellipses, and other regular or irregular geometric shapes. The length of the at least one safety device baffle 69 can be equal to, or less than, the length of the safety device 62.
The collection unit interface 64 can include any cavity, slot, slit, opening, vent, void, or other recessed or hollow space capable of receiving any solid, liquid, gas, or gaseous-like material. For example, the collection unit interface 64 can be configured to permit solid particulates to flow from a conduit 49 (as shown in
