DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular design for a free standing structure. However, it should be understood that the invention may be practiced in other embodiments that depart from these specific details.
Referring now to FIG. 1, a plan view of a free standing structure 100 is provided according to an embodiment. The free standing structure 100 may, for example, comprise an indoor free standing structure, or an outdoor free standing structure, or a combination thereof. Further, the free standing structure 100 may, for example, comprise a deck, a patio, a gazebo, or a shed.
As shown in FIG. 1, the free standing structure 100 comprises one or more modular platform structures 120 adjustably supported by a plurality of structural footings 110. The plurality of structural footings 110 may comprise one or more interior structural footings 112 configured for interior support of the free standing structure 100, one or more outer corner structural footings 114 configured for outer corner support of the free standing structure 100, one or more outer edge structural footings 116 configured for outer edge support of free standing structure 100, and one or more inner corner structural footings (not shown) for support of the free standing structure 100.
Also, as shown in FIG. 1, the free standing structure 100 may comprise a modular stair system 130. The modular stair system 130 comprises adjustable stairs having a first end configured to mate with at least one of the plurality of structural footings 110 and a second end configured to land on a ground surface. Alternatively, the modular stair system 130 comprises adjustable stairs having a first end configured to mate with at least one of the one or more modular platform structures 120 and a second end configured to land on a ground surface.
Referring now to FIG. 2, a perspective view of a structural footing 200 is provided according to an embodiment. The structural footing 200 comprises a support member 230 configured to provide vertical support to one or more modular platform structures, a base member 210, and an adjustable leveling mechanism 220 disposed between the support member 230 and the base member 210, and configured to level adjoining modular platform structures by adjusting a height of the support member 230 relative to the base member 210. The support member 230 may be configured to provide horizontal interconnectivity for the one or more modular platform structures.
The structural footing 200 may be configured for free standing structures, such as decks, patios, gazebos, or sheds that stand off the ground at any supportable height. As an example, the structural footing 200 may be configured for free standing structures that stand up to 30 inches off the ground in order to satisfy national building code which requires footings to extend below the frost level in geographic areas with frost for structures standing above 30 inches off the ground.
The structural footing 200 may provide both vertical support for modular platform structures, while providing adjustable leveling capability and horizontal support and/or connectivity that may have the ability to secure multiple, independent modular platform structures, such as structural decking sections and/or modules, into one combined structural unit or free standing structure. For instance, independent, structural deck modules can be leveled and joined together by a single footing device.
The adjustable leveling capability can have multiple, independent, adjustable vertical supports that will support and connect multiple, independent structural deck modules in one common footing. For example, a platform deck can have one inside corner adjustable footing that may be able to support and connect four independent structural deck modules. This footing provides an easy-to-use, easy-to-level deck footing for the do-it-yourself consumer or for a professional installer to save time and money.
Additionally, the structural footing 200 may have the ability to support and secure multi-level deck platforms in one common footing device. There may be different lengths of footings available to support a deck up to 30 inches off the ground. The different footing lengths may be necessary to keep a deck level in areas with sloping terrain or uneven terrain. Since each structural footing may have a maximum ability to adjust the platform, then the different lengths of footings may provide for improved application for terrains with more than several inches of change from the deck leveling between structural footings.
Further, each structural footing 200 may be able to accommodate multiple configurations for the support member 230 in one common base. This ability may allow for a structural footing that may be used for an inside corner, an outside corner, an interior vertex, or an outer edge (or run) for multiple modular structural platforms. These multiple securing plate configurations may be for inside corners, outside corners, interior vertices, outside edges, or even a change in height between modules for a multi-level free standing structure. Additionally, if the free standing structure is to be expanded in size, the same footings may be used and the support members may be changed to accommodate the new layout. Each structural footing allows for ease-of-use in assembling, and in disassembling in the case of re-leveling, moving to a new location or changing the layout.
As shown in FIG. 2, the structural footing 200 comprises base member 210 having a main footing 212, and an expanded (or flared) base 218 coupled to the main footing 212 to provide stability to the structural footing 200. The main footing 212 may comprise an upper footing section 214, a lower footing section 216 coupled to the upper footing section 214 and the expanded base 218, and a support table 215 coupled to the upper section 214.
The vertical position of the upper footing section 214 may be adjusted relative to the lower footing section 216. For example, a range for adjusting the upper footing section 214 relative to the lower footing section 216 may range from about 5 inches to about 25 inches. Alternatively, for example, a range for adjusting the upper footing section 214 relative to the lower footing section 216 may range from about 6 inches to about 20 inches. As shown in FIG. 2, the upper footing section 214 and the lower footing section 216 may comprise one or more fastening locations 217 configured to receive one or more fasteners 219.
Referring still to FIG. 2, the adjustable leveling mechanism 220 comprises one or more support bolts 222 having an end in contact with a bottom of the support member 230. The one or more support bolts 222 are configured to support and adjust the height of the support member 230 relative to the support table 215 of the base member 210. As shown in FIG. 2, the one or more support bolts 222 comprise threaded sections which intimately mate with tapped holes through the support table 215. As the one or more support bolts 222 are rotated through the tapped holes in the support table 215, the vertical height of the support member 230 may be adjusted.
Although the adjustable leveling mechanism 220 is shown to comprise one or more support bolts 222, other devices may be employed to adjust the support member 230 relative to the base member 210. The adjustable leveling mechanism 220 may comprise one or more slides with one or more latching devices. For example, the adjustable leveling mechanism 220 may comprise one or more first cylinders coupled to the support member 230 and one or more second cylinders, concentric with the one or more first cylinders, coupled to the base member 210. One or more spring-loaded devices coupled to an interior cylinder may insert a bolt or plug through holes that align between the interior cylinder and an exterior cylinder. The one or more spring-loaded devices may include a helical spring or loaded lever, for instance. Although in this example, cylinders are suggested other cross-sectional shapes may be used, including square cross-sections, rectangular cross-sections, or angle iron.
Alternatively, if the base member 210 is closed, hence, limiting access to the interior of the base member 210, the adjustable leveling mechanism 220 may comprise one or more support rods having a threaded end configured to mate with a top of the base member 210 and, when turned in the space between the support member 230 and the base member 210 causes adjustment of the height of the support member 230 and the base member 210.
A range for adjusting the support member 230 relative to the support table 215 using the one or more support bolts 222 may range from about 1 inch to about 5 inches. Alternatively, a range for adjusting the support member 230 relative to the support table 215 using the one or more support bolts 222 may range from about 1 inch to about 3 inches. This range may vary depending on the size and structural support strength of each support mechanism, for instance.
Referring still to FIG. 2, the support member 230 comprises an interlocking support plate 232 having the support surface configured to support the one or more modular platform structures. Further, the support member 230 comprises one or more interlocking members 234, such as interlocking walls, configured to mate with the one or more modular platform structures. These interlocking members will be in multiple layout configurations depending on both the number of modular platforms being secured and the specific type of fasteners being used for securing the modular platforms to the interlocking support plates.

For example, as shown in FIG. 6A, the support member 830 may comprise one or more interlocking members 832, such as interlocking posts, configured to insert into the joist structure 854 and secure horizontal movement and/or vertical movement of the one or more modular platform structures 850.
Although a deck is illustrated, the structural footing 800 may be configured for other free standing structures, such as patios, gazebos, or sheds that stand off the ground at any supportable height. As an example, the structural footing 800 may be configured for free standing structures that stand up to 30 inches off the ground in order to satisfy national building code which requires footings to extend below the frost level in geographic areas with frost for structures standing above 30 inches off the ground.
The structural footing 800 can provide both vertical support for modular platform structures, while providing adjustable leveling capability and horizontal support and/or connectivity that may have the ability to secure multiple, independent modular platform structures, such as structural decking sections and/or modules, into one combined structural unit or free standing structure. For instance, independent, structural deck modules can be leveled and joined together by a single footing device.
The adjustable leveling capability may have multiple, independent, adjustable vertical supports that may support and connect multiple, independent structural deck modules in one common footing. For example, a platform deck can have one inside corner adjustable footing that may be able to support and connect four independent structural deck modules. This footing provides an easy-to-use, easy-to-level deck footing for the do-it-yourself consumer or for a professional installer to save time and money.
Additionally, the structural footing 800 may have the ability to support and secure multi-level deck platforms in one common footing device. There may be different lengths of footings available to support a deck up to 30 inches off the ground. The different footing lengths may be necessary to keep a deck level in areas with sloping terrain or uneven terrain. Since each structural footing may have a maximum ability to adjust the platform, then the different lengths of footings may provide for a improved application for terrains with more than several inches of change from the deck leveling between footings.
Further, each structural footing 800 may be able to accommodate multiple configurations for the support member 830 in one common base. This ability may allow for a structural footing that may be used for an inside corner, an outside corner, an interior vertex, or an outer edge (or run) for multiple modular structural platforms. These multiple securing plate configurations may be for inside corners, outside corners, interior vertices, outside edges, or even a change in height between modules for a multi-level free standing structure. Additionally, if the free standing structure is to be expanded in size, the same footings may be used and the support members may be changed to accommodate the new layout. Each structural footing allows for ease-of-use in assembling, and in disassembling in the case of re-leveling, moving to a new location or changing the layout.
As shown in FIG. 6A, the structural footing 800 comprises base member 810 having one or more footing sections. For example, as illustrated in FIG. 6A, the base member 810 may comprise an upper footing section 814 and a lower footing section 812 coupled to the upper footing section 814. The upper footing section 814 and the lower footing section 812 are fixed height footing sections that may be stacked upon one another and interlocked to achieve a desired height for the free standing structure. For example, these fixed height footing sections may be available in different sizes, i.e., 3 inch sections, 6 inch sections, 12 inch sections, etc.; however, other sizes may be available As a result, the height of a free standing structure may be coarsely adjusted for a variety of terrains, including level terrain, sloped terrain, and mixtures thereof, using the fixed height footing sections when assembling the base member 810, and then finely adjusted using the adjustable leveling mechanism 820.
As indicated above, the upper footing section 814 and the lower footing section 812 may have an interlocking mechanism 813 and 815, respectively. The interlocking mechanism (813 and 815) may include an interlocking “T” that connects adjacent fixed height footing sections by sliding into a top surface of each footing section and twisting 90 degrees to lock. The interlocking “T” may be located in the center of the top surface of each footing section. As shown in FIG. 6A, the adjustable leveling mechanism 820 may be coupled to and interlocked with the base member 810.
Referring still to FIG. 6A, the adjustable leveling mechanism 820 comprises one or more support bolts 822 having an end in contact with a bottom of the support member 830. The one or more support bolts 822 are configured to support and adjust the height of the support member 830 relative to the base member 810. As shown in FIG. 6A, the one or more support bolts 822 comprise threaded sections which intimately mate with tapped holes supported within static member 824. As the one or more support bolts 822 are rotated through the tapped holes in the static member 824, the vertical height of the support member 830 may be adjusted.
Although the adjustable leveling mechanism 820 is shown to comprise one or more support bolts 822, other devices may be employed to adjust the support member 830 relative to the base member 810. The adjustable leveling mechanism 820 may comprise one or more slides with one or more latching devices. For example, the adjustable leveling mechanism 820 may comprise one or more first cylinders coupled to the support member 830 and one or more second cylinders, concentric with the one or more first cylinders, coupled to the base member 810. One or more spring-loaded devices coupled to an interior cylinder may insert a bolt or plug through holes that align between the interior cylinder and an exterior cylinder. The one or more spring-loaded devices may include a helical spring or loaded lever, for instance. Although in this example, cylinders are suggested other cross-sectional shapes may be used, including square cross-sections, rectangular cross-sections, or angle iron.
Referring now to FIG. 6B, a structural footing 800′ is illustrated when the adjustable leveling mechanism 820 is utilized to adjust the height of the structural footing 800′ by vertically elevating the support member 830 relative to the base member 810. One or more adjustment tools 856 are configured to extend through openings 857 in the decking platform, through the joist structure 854, and through the one or more interlocking members 832 to engage the one or more support bolts 822. For example, the openings 857 in the decking platform may include a quarter inch spacing set between adjacent platform boards 851 and trim boards 852 of the decking platform. Rotation of the one or more adjustment tools 856 (as illustrated in FIG. 6B) and the corresponding rotation of the one or more support bolts 822 causes vertical translation of the support member 830 relative to the base member 810.
A range for adjusting the support member 830 relative to the base member 810 using the one or more support bolts 822 may range from about 1 inch to about 12 inches. Alternatively, a range for adjusting the support member 830 relative to the base member 810 using the one or more support bolts 822 may range from about 1 inch to about 10 inches. Alternatively yet, a range for adjusting the support member 830 relative to the base member 810 using the one or more support bolts 822 may range from about 4 inches to about 7 inches. This range may vary depending on the size and structural support strength of each support mechanism, for instance.
As an example, referring to FIG. 8, a partial top view of footing structure 800 is illustrated in support of a modular platform structure at a corner thereof. The modular platform structure may include a decking platform having a plurality of platform boards and trim boards 905 supported in part by an interlocking joist 900, wherein the plurality of platform boards are not illustrated in order to reveal the underlying joist 900 and footing structure 800.
Referring now to FIGS. 9A and 9B, interlocking joist 900 and a modular joist structure 1000 within which the interlocking joist 900 may be assembled are illustrated, respectively, according to embodiments of the invention. As shown in FIG. 9A, the interlocking joist 900 may comprise one or more interlocking ledges 902, such as at either end of the interlocking joist 900, and one or more interlocking troughs 904, such as within the interior of the interlocking joist 900. Each interlocking ledge 902 and interlocking trough 904 may include either a mating post 906 or a mating receptacle 908. The mating receptacle 908 is configured to receive the mating post 906 in order to align and secure interlocking joist 900 with another interlocking joist. Further, the mating post 906 may be designed to be rotatable such that once the mating post 906 of interlocking joist 900 is aligned with and inserted into a mating receptacle of another interlocking joist, it may be rotated to lock the interlocking joists to one another.
As illustrated in FIGS. 9A and 9B, the interlocking joist 900 may be designed to be universal, i.e., reversible and interchangeable. As shown in FIG. 9B, interlocking joists 900A, 900B, 900C, and 900D are structurally the same, yet oriented differently within the modular joist structure 1000. For instance, interlocking joist 900A is flipped upside down relative to interlocking joist 900D. Therefore, any interlocking joist 900A, 900B, 900C, and 900D may be utilized in any position of the modular joist structure 1000. The universality of the interlocking joist 900 provides ease of packaging, ease of shipping, ease of storage, ease of retail display, and ease of use, among other things.
As shown in FIG. 9B, an interlocking ledge of an interlocking joist may mate with an interlocking trough of another interlocking joist, e.g., see the joinder of interlocking joist 900A with interlocking joists 900B and 900C in FIG. 9B. Additionally, an interlocking ledge of an interlocking joist may mate with an interlocking ledge of another interlocking joist, e.g., see the joinder of interlocking joist 900D with interlocking joists 900B and 900C in FIG. 9B. Furthermore, although not shown, an interlocking trough of an interlocking joist may mate with the interlocking trough of another interlocking joist.
The interlocking joist 900 may, for example, be manufactured using an injection molding process with a structural plastic or cast aluminum material.
Referring now to FIGS. 9A, 9B, 10A, 10B, and 10C, the interlocking joist 900 (or 900A) further comprises one or more receiving openings 910 (or 910A) configured to receive one or more fastening devices 950 configured to secure one or more of a plurality of platform boards 1050 to a module frame that may include the modular joist structure 1000 of FIG. 9B. For example, the one or more fastening devices 950 may be configured to mate with at least one of the plurality of platform boards 1050 and are configured to interlock with at least one of the one or more receiving openings 910 in the module frame.
The module frame, including any one of the decking platform, the platform board(s), the trim board(s), the fascia board(s), or the joist structure, may be fabricated from a single piece, such as molded from a structural plastic. This single piece module frame may be readily connected to and/or disconnected from structural footings.
As shown in FIGS. 10A and 10B, each of the one or more fastening devices 950 comprises a fastening strip 951 having fastening edges 952 and 954 configured to mate with a groove formed in the edge of at least one of the one or more platform boards 1050. Additionally, each of the one or more fastening devices 950 comprises one or more fastening members 960 configured to insert into the one or more receiving openings 910 in the module frame and slide in the one or more receiving openings 910 to lock each of the one or more fastening devices 950 to the module frame. Each fastening member 960 comprises a latching member 962 and a wall member 964 extending between the fastening strip 951 and the latching member 962.
As shown in FIGS. 10A, 10B, and 10C, the fastening strip 951 initially engages the one or more platform boards 1050 such that the wall member 964 extends from the fastening strip 951 between the one or more platform boards 1050 while the latching member 962 extends into a first opening 912 of at least one of the one or more receiving openings 910 (position “A”). As illustrated in FIG. 10C, the first opening 912 has an area sufficiently large to receive the latching member 962 of the fastening member 960. Thereafter, the fastening strip 951 secures the one or more platform boards 1050 when the fastening strip 951 slides from the first opening (position “A”) to a second opening 914 (position “B”), wherein the second opening 914 is smaller than the first opening 912 yet sufficiently large to allow the wall member 964 to extend there through. In position “B”, the latching member 962 is captured by the receiving opening 910 in interlocking joist 900.
Referring now to FIG. 11, a partial perspective view of a free standing structure 1100 is provided according to yet another embodiment. The free standing structure 1100 comprises the plurality of platform boards 1050, and the modular joist structure having one or more interlocking joists 900, wherein the modular joist structure is configured to support the plurality of platform boards 1050. Additionally, the free standing structure comprises one or more fastening devices 950 configured to secure the plurality of platform boards 1050 to the modular joist structure via receiving openings 910 in the interlocking joists 900. Furthermore, the free standing structure 1100 may comprise a plurality of structural footings (not shown) configured to adjustably support the modular joist structure.
