BACKGROUND OF THE INVENTION
Field of Invention
The present application is in the field of paving subsurfaces with pavers.
Background of the Invention
Subsurfaces are frequently paved to adjust the aesthetic and/or physical properties of the subsurface. Sometimes, paving s accomplished via placing an array of pavers onto the subsurface. Therefore, a need exists for an apparatus and related methods that facilitate the paving of a subsurface with a paver.
Often, leveling and/or elevation of the paved surface relative to the subsurface are necessary. For instance, raising or elevating the paved surface relative to the subsurface can facilitate drainage of the paved surface or provide for air circulation between the paved surface and the subsurface (e.g., to prevent the buildup or mold or other residue). Furthermore, leveling the paved surface can correct an undesirably irregular or sloped undersurface. As a result, there is a need for an apparatus and related methods which facilitate the elevated and leveled placement of a paved surface onto a subsurface.
Pedestals can be used to elevate a paved surface relative to a subsurface. For instance, in U.S. Pat. No. 8,850,753, a pedestal is disclosed that supports the corners of an elevated paver. Pedestals frequently feature slope compensating mechanisms for leveling the elevated paver surface relative to the subsurface. Two common slope compensating mechanisms are: cooperating twist slope adjustment (see e.g., U.S. Pat. Nos. 6,332,292 and 5,442,882); and concave/convex interacting surfaces (see e.g. U.S. Pat. No. 3,318,057). Twist slope manipulation only allows for slope adjustment at the paver support surface instead of at the pedestal base whereby the pedestal can become unbalanced. Concave/convex surface slope compensation is not adequate since the concave/convex surface interactions are relatively frictionless and unstable so that additional components are needed to keep the paver support surface from shifting orientation. See U.S. Pat. No. 3,318,057, FIG. 2, element 70; see also U.S. Pub. Pat. App. No. US2008/0222973, FIGS. 4 and 5, element 132, 134 and 72. Accordingly, a need still exists for a pedestal and related methods which facilitate the elevated and leveled placement of a paved surface onto a subsurface.
When pedestals are used for elevation or slope compensation of a paved surface, problems can arise when the pavers are not coupled to the pedestal. For example, a paver can fall or otherwise shift position to increase paver installation or ruin the paver pattern. Thus, many have designed mechanisms for coupling the paver to a pedestal. In the pedestal disclosed by Knight, III et al. (U.S. Pat. No. 8,302,356), the corners of four wooden pavers are anchored to a support pedestal via a washer that turns into a notch in the pavers' corner. See FIGS. 9-11. This washer features a cut-away portion so that the panels can be unanchored to the pedestal via aligning the cut-away portion with one of the four anchored corners. Problems can arise when the cut-away portion accidentally aligns with one of the paver corners wherein the paver may still be allowed to fall out of place or otherwise misalign. Thus, a need exists for apparatus and related methods of anchoring a paver to a pedestal.
Problems also arise in elevated and slope adjusted paved surfaces when small pavers are used because such small pavers cannot span between two pedestals. As a result, support surfaces are provided between the paver and the pedestal. See, e.g., U.S. Pat. No. 8,128,312. However, intermediate surfaces can be problematic for adding or reproving heat from the paver surface. Exchanging heat with a paved surface is sometimes desirable. Heat is frequently provided to cold paved surfaces to melt snow on paved surfaces (e.g., a driveway of a home) in cold environments. Similarly, heat may be removed from a paved surface in hot environments to prevent discomfort to those walking bare-foot on the paved surface (e.g., a pool-side paved surface). As a result, there is a need for pedestals, intermediate paver support surfaces, and related methods which facilitate the elevated, leveled, heated or cooled placement of a paved surface onto a subsurface.
SUMMARY OF THE INVENTION
It is an object of the present application to disclose apparatus and related methods for facilitating the elevated and leveled placement of a paver array onto a subsurface. In one embodiment, such an apparatus may be defined by two cooperating slope compensation panels that are disposed underneath a paver support pedestal. Each panel has a top surface and a bottom surface, wherein the bottom surface of one panel is configured for receiving the top surface of the other panel, and wherein the top surface is configured to be received by the bottom surface of the other panel or by the bottom of the pedestal. Suitably, the bottom surface of one panel features a slope relative to the top surface of the bottom panel so that the slopes of each panel compound or offset with the relative rotation of each panel with respect to each other. In one mode of operation, (A) the panels may be coupled and rotated relative to each other to compensate for a slope of an undersurface and (B) a pedestal may be positioned on the panels so that the pedestal's paver support surface is level relative to the subsurface.
It is also an object of the present application to disclose an anchoring mechanism for securing a paver to a pedestal. In one embodiment, the apparatus is a locking disk that may be positioned at the corners of a plurality of pedestals and inserted into a disk slot through the corners. In a preferred embodiment, the locking disk is a full circle that features a perforated break-away to assist in the unanchoring of the pavers whenever necessary. In operation, the locking disk works similar to the apparatus disclosed in by Knight, III et al, (U.S. Pat. No. 8,302,356) except the pavers are anchored with a full disk without a cutout. In another embodiment, the apparatus is a locking slider that may be positioned between two pavers and slid into slots in the corners of the two pavers, and then slid backward into so that the slider is positioned in the slot of four paver corners.
Finally, it is an object to provide an intermediate surface for supporting a small paver and that can also be used to exchange heat with the pavers. In one embodiment, the apparatus may be a tray, such as a hextray defined by a frame with a hexagonal lattice for supporting pavers. The tray preferably features a tubing track throughout the lattice to accommodate heat exchange tubing. In operation the tray may be positioned above a pedestal or directly on a subsurface. In embodiment, the tray may be outfitted with insulation and a metal plate so that heat may be exchanged with pedestals via fluid passing through tubing installed throughout the lattice. In a preferred embodiment, the tray features a slot in its corners for receiving a locking disk or locking slider.

The detailed description set forth below in connection with the appended drawings is intended as a description of presently preferred embodiments of the invention and is not intended to represent the only forms in which the present invention may be constructed or utilized. The description sets forth the functions and the sequence of steps for constructing and operating the invention in connection with the illustrated embodiments. It is to be understood, however, that the same or equivalent functions and sequences may be accomplished by differ embodiments that are also intended to be encompassed within the spirit and scope of the invention.
Disclosed may be an apparatus and related methods for facilitating the elevated and leveled placement of a paver array onto a subsurface. Each component will be described separately, followed by descriptions of specific examples by mixing and matching the various components. The examples are for illustrative purposes only. The invention is not limited to the examples shown. Having described each component separately, and having provided some examples of how the components work together, a person of ordinary skill in the art would be able to come up with many different combinations of the components described. Furthermore, each component may be used with prior art devices as well. Although the reference numbers change for similar components and subcomponents within different examples, it is to be understood that the features described for each component or subcomponent for any example applies across each example regardless of the different reference numbers. The reference numbers were merely chosen as a convenient way to identify the different examples being described for ease of description.
In general, with reference to FIG. 56A-56B a plurality of pedestals or pedestal assemblies 9000-9000d are placed on a subsurface to elevate a set of trays 9100-9100b. A paver 10 is placed on top of the trays 9100-9100b to create a flat, even surface. In some embodiments, to account for uneven subsurfaces, the pedestal 9000 may have an adjustable, self-leveling cap 9020 at the top of the pedestal 9000. Alternatively, or in addition to the cap 9020, a compensation pad 2000 may be provided at the bottom of the pedestal 9000 to adjust the angle of the pedestal relative to the subsurface. As shown in FIGS. 57A-57B, in some embodiments, lateral braces 9300a-9300c may be provided to interlock the plurality of pedestals 9000-9000d for stability. In some embodiments, a buffer 9400 may be provided to increase the surface area of the pedestal 9000 to reduce sinking of the pedestal 9000 into the subsurface. In some embodiments, a pipe riser spacer 9500 may be provided to hold and elevate pipes and other conduits.
With reference to FIGS. 58A-59, the pedestal 9000 provides a foundation upon which the pavers 10 can be mounted so as to be elevated and to provide the means for leveling the pavers. As shown in FIGS. 58A-58C, the pedestal 9000 comprises a base 9001 having a foot 9002 and a support cylinder 9004. The foot 9002 has a flat surface 9003 defining an outer perimeter 9005. In the preferred embodiment, the foot 9002 may be a flat, circular disk; however, any shape can be used.
The support cylinder 9004 projects perpendicularly away from the foot 9002. The free terminal end of the support cylinder 9004 will be referred to as the top 9006. Although the support cylinder 9004 is preferably cylindrical in shape, any other shape can be used. The support cylinder 9004 may be a hollow cylinder with an open top, a hollow cylinder with a closed top, or a solid cylinder. In embodiments in which the support cylinder 9004 is hollow with an open top, the inner wall 9008 of the support cylinder 9004 may be smooth or may comprise threads 9010. Since the threads 9010 are on the inner wall 9008 of a hollow cylinder, these threads are referred to as feminine threads.
In some embodiments, the base 9001 may further comprise an outer cylindrical wall 9012. The outer cylindrical wall 9012 may be concentrically arranged about and spaced apart from the support cylinder 9004 to define a riser socket 9014 therebetween. In between the outer perimeter 9005 of the foot and the oyster wall 9012 may be one or more openings 9016 through the surface 9003 of the foot 9002. In the preferred embodiment, there may be a plurality of openings 9016 intermittently and angularly spaced apart around the foot 9002. The openings 9016 are configured to receive the lateral braces as discussed further below.
A cap 9020 may connect to the top 9006 of the support cylinder 9004 to interface with the pavers 10. As described in further detail below, the cap 9020 can be configured in various ways to create a self-leveling surface for the pavers. In some embodiments, the cap 9020 comprises male threads 9021 to mate with the feminine threads 9010 of the support cylinder 9004.
The height of the support cylinder 9004 generally determines the height of the pedestal 9000, which in tarn determines the elevation of the pavers. In some embodiments, a coupler 9030 may be provided to add to the height of the support cylinder 9004. The coupler 9030 attaches to the support cylinder 9004 to add to the height of the support cylinder 9004. For example, the coupler 9030 may have outer threads 9032 that mate with the feminine threads 9010 of the support cylinder 9004. Such a threaded coupler 9030 fits inside the support cylinder 9004 and screws in and out of the support cylinder 9004 to adjust the final height of the pedestal 9000. Alternatively, the coupler 9030 may be ribbed or notched and the inner wall 9008 of the support cylinder 9004 may have reciprocal ribbing or notches so that the coupler 9030 can snap into place at various heights. Other methods of adjusting the height can be used, including automatic height adjustments using electric motors. These alternative height adjusting mechanisms can be applied to any threaded connection described herein. In embodiments utilizing a coupler 9030, the top 9035 of the coupler 9030 may be configured to connect with the cap 9020 as discussed further below.
With reference to FIG. 59, in some embodiments, the coupler 9030 may comprise reversed threading 9036 adjacent to the outer threads 9032. Therefore, a bottom portion of the coupler 9030 may comprise the outer threads 9032 and a top portion of the coupler 9030 may comprise the reversed threading 9036. The reversed threading 9036 may attach to inner threads 9024 of the cap 9020. Normally, if the threading was uniform in one direction along the length of the coupler 9030, and the bottom of the coupler was placed on top of the support cylinder 9004, then rotation of the coupler 9030 in a first direction would cause the coupler 9030 to move into the support cylinder 9004. If a cap 9020 was placed on top of the coupler 9030, then rotation in the first direction would also cause the coupler 9030 to move out of the cap 9020. Therefore, if the user wanted to change the height of the paver, by rotating the coupler in the first direction, the coupler 9030 driving into the support cylinder 9004 at the bottom end, and the coupler 9030 coming out of the cap 9020 at the top end would effectively cancel each other out the cap 9020 and the support cylinder 9004 were fixed.
With the reversed threading 9036, however, the reversed threads 9036 would be in the opposite direction relative to the outer threads 9032. This way, in the example above, when the coupler 9030 is rotated in the first direction, the coupler 9030 would drive into the support cylinder 9004 while simultaneously driving into the cap 9020 to effectively close the distance between the cap 9020 and the support cylinder 9004 or the base 9001. Conversely, rotating the coupler 9030 in a second direction, opposite the first direction, would cause the coupler 9030 to exit the support cylinder 9004 while at the same time exiting the cap 9020 to effectively increase the distance between the cap 9020 and the support cylinder 9004 or the base 9001. Because there is opposite movement at both ends of the coupler 9030 with rotation of the coupler 9030 in one direction, the distance between the cap 9020 and the base 9001 opens or closes faster than without the reversed threading 9036.
In some embodiments, the coupler 9030 may further comprise a lever 9038 to facilitate turning the coupler 9030. The lever 9038 may project radially outwardly from the body of the coupler 9030. In the preferred embodiment, the lever 9038 is like a sprocket with multiple projections protruding radially outwardly from the body of the coupler 9030 and angularly spaced apart from each other to provide multiple places to grab to rotate the coupler 9030.
The height of the pedestal 9000 can be further extended by including a riser 9040. Preferably, the riser 9040 is a hollow tube that is cylindrical in shape. Other shapes may be used, but the shape of the riser 9040 should be the same as the shape of the support cylinder 9004. The similarity in shape allows the riser 9040 to fit inside or outside of the support cylinder 9004. In the preferred embodiment, the inner diameter of the riser 9040 is substantially similar to the outer diameter of the support cylinder 9004 so that the riser 9040 can fit around the support cylinder 9004 and be secured to the support cylinder by resistance fit. More preferably, the inner diameter of the outer wall 9012 of the base 9001 is substantially similar to the outer diameter of the riser 9040 so that the riser 9040 can be seated within the riser socket 9014 and be secured by resistance fit between the support cylinder 9004 and the outer wall 9012. The resistance fit is the preferred method of securement of the riser 9040 so that off-the-shelf PVC pipes can be cut to desired lengths and be used as the riser 9040. Due to the symmetry of the riser 9040, the base 9001 can be attached to either end of the riser 9040.
In embodiments utilizing the riser 9040, a collar 9050 may be provided. The collar 9050 is shaped to match the shape of the riser 9040. In the preferred embodiment, the collar 9050 is cylindrical in shape and may have a double wall, an outer wall 9052 concentrically arranged about and spaced apart from an inner wall 9054 so as to define a riser socket 9056 just like the base 9001. The collar 9050 can, therefore, be seated on top of the riser 9040 by inserting the riser inside the riser socket 9056 of the collar 9050. The inner wall 9054 of the collar 9050 may be threaded 9058 so as to receive the coupler 9030. The cap 9020 can be attached to the coupler 9030 to receive the paver. Alternatively, the cap 9020 can be attached directly to the collar 9050.
Therefore the cap 9020 can be attached directly to the base 9001 to create a short pedestal 9000. Alternatively, the cap 9020 can be attached to a coupler 9030 attached to the base 9001 to create a pedestal 9000 of intermediate height. Alternatively, the cap 9020 can be attached to a coupler 9030 that is attached to a riser 9040 that is attached to the base 9001 to create the tallest pedestal 9000.
In embodiments, compensation pads 2000 may be provided to adjust the angle of the pedestal to accommodate various subsurface terrains as discussed further below.
A tray 9100 may attach to the pedestal to provide a surface area for the pavers to lay on. As shown in FIGS. 60A-60B, the tray 9100 comprises a frame 9102 defining a paver support surface 9104 configured to support the paver. Preferably, the frame 9102 is a rectangular or square shape so that multiple trays 9100 can be efficiently placed adjacent to each other to create a large surface area for the pavers. Many other geometric shapes be used to achieve the same result.
In addition, the frame 9102 may be configured to creating a lattice. In some embodiments, the tray 9100 may be configured as a heat exchanger to provide heat or cooling to the pavers as described further below. For example, tubing tracks 9107 may be created on the paver support surface 9104 through which fluids can be passed having the desired temperature. In some embodiments, is desirable to configure the frame 9102 to be attached to the paver with a fastener in a manner that prevents the paver from being knocked off the tray 9100. For example, the paver support surface 9104 of the frame 9102 may comprise a well 9106. In the preferred embodiment, the well 9106 is adjacent to one of the corners of the frame. More preferably, at least one well 9106 may be positioned adjacent to each corner of the frame 9102. The well 9106 is a recessed portion of the paver support surface 9104 capable of retaining a fastener inside. For example, the fastener may be an adhesive, such as glue, that can be poured inside the well 9106 until the well 9106 is filled. Placing a paver on top of the frame 9102 will allow the paver to adhere to the frame 9102 at the well 9106. In the preferred embodiment, the well may contain protrusions 9108. The protrusions 9108 create more surface area for the adhesive to stick to. For example, the protrusions 9108 may be a plurality of ribs protruding upwardly from the bottom of the well 9106. Other types of fasteners may be used such as nails, screws, hooks, magnets, and the like. The wells 9106 may be strategically placed anywhere on the paver support surface 9104.
As will be described further below, the tray 9100 may comprise slots 9112 on the sides of the tray 9100, preferably at the corners, parallel to the paver support surface 9104 to receive a locking mechanism 9114 that allows the tray 9100 to connect to the pedestal 9000.
In some embodiments, the trays 9100 configured to hold pavers can be replaced with a potting trays 9600-9600b used to hold plants and flowers as shown in FIGS. 61A-61K. The potting 9600 comprises a frame defined by a floor 9602 and one or more sidewalls 9604a-d defining a container with an open top. Like the paver tray 9100, the potting tray 9600 comprises slots 9606 on the one or more sidewalls 9604a-d so that the potting tray 9600 can be elevated and, optionally, leveled using the pedestal 9000 as discussed with the paver tray 9100.
In the preferred embodiment, the potting tray 9600 is square shape having four sidewalls 9604a-d. Each side wall 9604a-d may have a cutout 9608a-d. In the preferred embodiment, the cutout is in the shape of a semi-circle; however, any shape can be used. Preferably, two adjacent sidewalls will further comprise a connector 9610 protruding away from its respective sidewall to create a lip 9612. The lip 9612 is in the shape of the cutout 9608 and configured to mate with the cutout 9608 of an adjacent potting tray 9600. This allows two adjacent potting trays 9600 to connect with each other. Therefore, a first potting tray 9600a can be connected to an adjacent potting tray 9600b by hooking the lip 9612 of the first tray 9600a to the cutout 9608 of the second tray 9600b. This ability to connect to each other creates a modular planting system.
In some embodiments, the floor 9602 comprises a plurality of separated troughs 9620 defined by barriers 9622. The troughs 9620 allow the potting tray 9600 hold water and soil. In some embodiments, a filter layer may be placed on top of the barrier 9622 to allow separation of the soil from the water. Therefore, the water may be placed in the troughs 9620 with the filter layer on top of the barriers 9622, and the soil placed on top of the filter layer. The filter layer may have large enough holes to allow the roots from the plants to reach down into the trough for water while keeping the soil above the water. The trough can be used to hold other items for promoting the growth or stabilization, such as rocks, nutrients, and the like.
In some embodiments, the floor 9602 may further comprise a covered conduit 9624 to allow plumbing to pass through, such as hoses, cables, wires, and the like. This allows hoses to pass from one side of the potting tray 9600 to the opposite side, underneath the soil to maintain a clean and aesthetic appearance. Since the conduit 9624 is covered, the soil cannot interfere with the passage of the hose through the conduit.
In some embodiments, the floor 9602 may comprise a plurality of holes 9626 through which water can be fed into the potting tray 9600. In some embodiments, these holes 9626 may be in fluid communication with the covered conduit 9624 so that water released from hoses in the covered conduit 9624 can come out into the troughs 9620 via the plurality of holes 9626. In some embodiments, these holes 9626 may be on the barriers 9622 and the barriers 9622 may form the covered conduit 9624.
As shown in FIG. 57A-57B a lateral brace 9300 may be used to stabilize the pedestals 9000 relative to each other. Referring to FIGS. 62A-62N, the lateral brace 9300 is an elongated arm 9302 comprising a first end 9304 and a second end 9306 opposite the first end 9304. The first and second ends 9304, 9306 each comprise a projection 9308, 9310. These projections 9308, 9310 are configured to fit within the openings 9016 of the base 9001. In particular, the projection 9308 at the first end 9304 of the lateral brace 9300 is inserted into a first opening 9016a of a first pedestal 9000a, and the projection 9310 at the second end 9306 of the lateral brace 9300 is inserted into the opening 9016b of a second pedestal 9000b, thereby linking the two pedestals together. Continuing this process to link multiple pedestals together creates a sturdy foundation of pedestals.
In some embodiments, the lateral braces 9300 may attach to a stabilization bar collar 9350 that is attached to the riser. In essence the stabilization bar collar 9350 may be much like the base 9001 with a through-hole in the center so that the stabilization bar collar 9350 can be slid up and down on the riser at a desired height. The stabilization bar collar 9350 comprises openings 9352. In some embodiments, the openings 9352 may further comprise notches 9353 at opposite ends to facilitate receiving the lateral brace. In some embodiments, for each opening 9352, a pair of guide walls 9354 may be bilaterally arranged about their respective opening 9352. The guide walls 9354 help with the connection of the lateral brace. In some embodiments, these features that allow the connection to the lateral braces 9300 may be on the base 9001.
In the preferred embodiment, the elongated arm 9302 of the lateral brace 9300 comprises two separate arms 9312, 9314 attached to each other at one side. Each arm 9312, 9314 may comprise a set of teeth 9316, 9318 through which the two arms 9312, 9314 can be attached. This allows the arms 9312, 9314 to attach to each other at first locations along the arm, thereby making the elongated arm telescopic so as to adjust the total length of the elongated arm 9302. Fasteners 9320, such as a nut and bolt, may used to secure the two separate arms 9312, 9314 together. The first and second ends 9304, 9306 may each further comprise a tab 9322, 9324. The tabs 9322, 9324 provide a flat surface from which the projections 9308, 9310 protrude perpendicularly. The tabs 9322, 9324 may have angled sidewalls 9326, 9328 that match the angle of the guide walls 9354 of the stabilization bar collar 9350.
In some embodiments, the first and second ends 9304, 9306 may each comprise projections 9308, 9310. In such case, the stabilization bar collar 9350 would have corresponding openings 9352 to receive the plurality of projections 9306, 9308. The guide walls 9354 would abut against the angled sidewalk 9326, 9328.
In some embodiments, the projections 9308, 9310 may further comprise opposing protruding lips 9330, 9332. These protruding lips 9330, 9332 snap into the notches 9353 of the openings 9352 on the stabilization bar collar 9350.
FIGS. 63A-64D show the stabilization bar collar 9350 and locking sleeve 9370. The stabilization bar collar 9350 may further comprise a threaded cylinder 9360 projecting perpendicularly away from the plane of the stabilization bar collar 9350 as shown in FIGS. 64A-D. Once the stabilization bar collar 9350 is positioned at the desired height on the riser 9040, the locking sleeve 9370 may be threaded onto the threaded cylinder 9360 causing the threaded cylinder to tighten around the riser 9040, thereby locking the stabilization bar collar 9350 in place. To allow for the threaded cylinder 9360 to move radially inward and outward relative to the riser 9040, the threaded cylinder may have a plurality of vertical slits 9362 intermittently and angularly spaced around the threaded cylinder 9360.
As shown in FIGS. 65A-65E, the buffer 9400 may be a flat pad with a larger surface area than the foot 9002 of the pedestal 9000. The buffer 9400 has a top side 9402 and a bottom side 9404. The top side 9402 comprises one or more raised walls 9406 projecting perpendicularly in the upward direction. The raised wall 9406 is in the shape of the foot 9002 and substantially the same size as the foot 9002 so that the foot 9002 can be seated within the raised wall 9406. In some embodiments, the top surface may further comprise a plurality of stops 9408. The stops 9408 may be positioned on the outer side of and spaced radially away from the raised wall 9406 and angularly spaced apart around the raised wall 9406.
With reference to FIGS. 66A-66M, in some embodiments, rather than supporting pavers, the pedestals 9000 may support beams or pipes. Therefore, rather than connecting a cap 9020 onto the pedestal 9000, a walled spacer 9500 may be attached to the top of the pedestal 9000. The wailed spacer 9500 may comprise a platform 9502 having a top surface 9504 and a bottom surface 9506. The bottom surface 9506 is configured to attach to the pedestal 9000 like the cap 9020. Therefore, features of the cap 9020 that allow the cap 9020 to attach to the pedestal 9000 apply to the walled spacer 9500, such as the convex portion 9505 on the bottom surface 9506 for self-leveling, and a central orifice 9507. The top surface 9504 of the wall spacer 9500 comprises curved walls 9508a, 9508b projecting perpendicularly upwardly from the top surface 9504. The curved walls 9508a, 9508b are arranged about the central orifice 9507 such that the convex curvature of each wall 9508a, 9508b faces toward each other and toward the central orifice 9507 and define the closest points of the curved walls 9508a, 9508b to each other. The concave curvature of each wall 9508a, 9508b face towards the outer perimeter 9509 of the platform 9502 on their respective sides.
In some embodiments the curved wall 9508a transitions into flat wall portions 9510a, 9512a at its terminal ends 9514a, 9516a. Similarly, curved wall 9508b transitions into flat wall portions 9510b, 9512b at its terminal ends 9514a, 9516b. Contralateral and opposite flat wall portions of the two curved walls 9508a, 9508b may be parallel to each other, but not in line with each other. For example, flat wall portion 9510a of the first curved wall 9508a may be parallel to flat wall portion 9512b of the second curved wall 9508b. Similarly, flat wall portion 9512a of the first curved wall 9508a may be parallel to the flat wall portion 9510b of the second curved wall 9508b. 
This configuration allows beams or joists of various sizes to fit within the same walled spacer 9500 simply by rotating the walled spacer 9500 in the proper direction. For example, with reference to FIG. 66K, the first flat wall portion 9510a of the first curved wall 9508a defines a first imaginary line 9520a. The second flat wall portion 9512b of the second curved wall 9508b defines a second imaginary line 9520b that is parallel to and spaced apart from the first imaginary line 9520a. Likewise, the second flat portion 9512a of the first curved wall 9508a defines a third imaginary line 9522a and the first flat portion 9510b of the second curved wall 9508b defines a fourth imaginary line 9522b. The fourth imaginary line 9522b is parallel to and spaced apart from the third imaginary line 9522a. The distance between the first and second imaginary lines 9520a, 9520b may be different from the distance between the third and fourth imaginary lines 9522a, 9522b. In this respect, the curved walls can accommodate beams or joists of at least two different widths. Furthermore, the distance between the curved portions of the curved walls 9508a, 9508b can also be different from the distance between the first and second imaginary lines 9520a, 9520b and the third and fourth imaginary lines 9522a, 9522b. This allows the walled spacer 9500 to accommodate beams or joists of at least three different widths as shown in FIGS. 66C-D and FIGS. 66F-G. In general, the distance between the curved portions of the curved walls 9508a, 9508b may be greater than the distance between imaginary lines 9520a, 9520b and 9522a, 9522b. In use, a beam or joists may be positioned in between the curved portions of the curved wall 9508a, 9508b. If the width of the beam is too small, then the walled spacer 9500 can be rotated clockwise or counterclockwise so that the length of the beam or joists is parallel to either the first and second imaginary lines 9520a, 9520b or the third and fourth imaginary lines 9522a, 9522b. 
In some embodiments, each curved wall 9508a, 9508b may comprise a notch 9530a, 9530b defining the upper edge of the curved wall 9508a, 9508b. The notches 9530a, 9530h are configured to receive a roller 9532. The roller 9532 mounted upon the notches 9530a, 9530b allows a beam, joist, or some other elongated object, to be placed upon the roller 9532 for easy movement of the elongated object. The roller 95 generally a cylindrical structure defined by a sidewall 9534 and two opposing ends 9536, 9538. Preferably, the sidewall 9534 tapers towards the middle to create an hour-glass shape. Protruding perpendicularly outwardly from each opposing and 9536, 9538 is a peg 9540, 9542. The pegs are mounted on opposite curved walls 9508a, 9508b at their respective notches 9530a, 9530b. Preferably, notches 9530a, 9530b are located approximately at the curved portion of the curved walls 9508a, 9508b. 
Having described the various components of the present invention, a person of ordinary skill in the art would be able to combine the various components in a variety of ways to create a paver elevating system. And some of the components can stand alone as independent inventions. Below are specific examples of combinations of the components described above. The invention, however, is not limited only to the examples below. Many variations can be derived from the examples below and the description above.
In one embodiment, such an apparatus may be defined by two cooperating slope compensation panels that are disposed underneath a paver support pedestal. Each panel has a top surface and a bottom surface. Suitably, the bottom surface of a top panel features a slope relative to the top surface of a bottom panel so that the slopes of each panel compound or offset via the relative rotation of each panel with respect to each other. In one erode of operation, (A) the panels may be coupled and rotated relative to each other to compensate for a slope of an undersurface and (B) a pedestal may be positioned on the panels so that the pedestal's paver support surface is level relative to the subsurface. The details of the preferable panel are best disclosed by reference to FIGS. 1 through 10.
It should be noted that, now, and throughout the application the terms “top” and “bottom” or “lower” and “upper”, or any other orientation defining term should in no way be construed as limiting of the possible orientations of the panel 1000 (i.e., the panel 1000 may be positioned sideways, or in reversed vertical orientations even though the specification refers to a “top” and “bottom” parts).
FIG. 1 is a pedestal 1000 for elevating a paver surface. The pedestal 1000 is disclosed in U.S. Pat. No. 8,850,753, and that document is hereby incorporated in its entirety. As disclosed in that document, the pedestal 1000 has a slope compensation mechanism at its paver support surface, but not its base. In one embodiment, the disclosed apparatus is a slope compensation disk 2100 that, when stacked with a like disk, provides a footing for a pedestal 1000 that is configured to compensate for the slope of the subsurface.
Referring now to FIG. 4, the pedestal 1000 may be positioned on a slope compensation panel 2000 defined by two or more slope compensation disks 2100. FIGS. 2 and 3 illustrate how two panels might be stacked. As alluded to above, the disks 2100 are configured with a top surface plane that is angled relative to the plane of its bottom surface. The top surface plane of a first panel 2100 may interact with a bottom surface plane of a second panel to result in the compounding or offsetting of disks 2100 respective angle. As shown in the figure, the pedestal 1000 on the right is on a panel 2000 that has the angles of its disks 2100 offset while pedestal 1000 on the left is on a panel 2000 that has had the angles of the stacked disks 2100 compounded. FIG. 2 is a side view of the pedestal 1000 being positioned over two slope compensation panels 2000.
FIGS. 5 and 6 respectively depict bottom and top perspective views of the slope compensation panel 2000. FIGS. 7 through 10 respectively depict top, bottom, left side, and right side view of the compensation panel 2000. As can be seen in the referenced drawings, the panel 2000 is generally a truncated tubiform and may comprise: feet 2110; an outer wall 2120; an established top surface 2130 on at least a part of one end of the truncated tubiform; an established bottom surface 2135 on the underside of the panel 2100; an attachment receptacle 2140 on the top surface 2130; an inner wall 2150 accessible at the unclosed end of the component's 1 truncated tubiform; and the underside 2160 of the surface 2130. FIGS. 5 through 10 suitably illustrate the above referenced components of the depicted panel 2000.
The feet 2110. The feet 2110 are best depicted in FIGS. 5, 6, 7, 9, and 10. As seen in the cited figures, the feet 2110 may generally be a rim or portion thereof or distal projection around the open end of the panels 2000 truncated tubiform. As such, the feet 2110 feature lower (see FIG. 7) surfaces 2112. Operably, the feet 2110, via the lower surface 2112, may uprightly support a panel 2000 on a subsurface when such is positioned with its open end against the subsurface. In an alternate embodiment (see, e.g., FIG. 4, the feet 2110 may be positioned on a base plate). Further, as discussed below, because the panel 2100 is configured to receive/retain items within its tubiform, the foot 2110 may further define a gripping means for facilitating the receipt/retention and/or removal of such items.
The outer wall 2120. The outer wall 2120 is best depicted in FIGS. 5, 6, 9 and 10. As seen in the figures, the outer wall 2120 may suitably be the external portion of the component's tubiform. As such, the outer wall 2120 generally extends between the foot 2110 and the surface 2130. As is further depicted, the outer wall 2120 is suitably divided at a midpoint by a step 2122 into lower 2121 and upper 2123 sections. As seen in FIGS. 9 and 10, the upper portion 2123 is offset from the lower portion 2121 in terms of the component's external diameter to generally define the step 2122 (see also FIG. 5). As further seen in FIGS. 5, 9, and 10, the step 2122 generally defines a plane that is oblique to the plane of the bottom surface 2135. The oblique angle is generally referenced by angle 2124. Preferably, the step 2122 is disposed on the outer wall 2120 at a location that is more toward the top surface 2130 end of the panel 2000, but the top plane of the surface 2130 should suitably be above the plane of the step 2122 and the plane of the bottom surface 2135.
When a panel is used in isolation, as discussed further below, the top surface 2130, the step 2122, and bottom surface 2135 suitably serve only aesthetic purposes. However, when used in conjunction with a like panel 2100 (i.e., more than one panel 2100) the step 2122 and surface serves as a means for altering the slope of the surface 2130 with respect to a subsurface. This functionality is discussed later below.
The top surface 2130 and bottom surface 2135. The top and bottom surfaces 2130, 2135 are best seen in FIGS. 5, 6, 7, and 8. Referring to these figures, the surface 2130 generally encloses one end of components tubiform to establish a load bearing surface. The bottom surface 2135 generally defines a plane on the bottom of the panel 2000. Operably, the top surface 2130 is adapted for receiving a pedestal (see e.g., FIG. 2) whereby the pedestal is supported above a subsurface by the panel. For example, a panel 2000 used in isolation may, after being placed feet 2110 down on a subsurface or base plate, receive a pedestal on its top surface 2130 whereby the paver is above the subsurface.
The attachment receptacle 2140. Referring now to FIGS. 5, 6, 7 and 8, the top surface 2130 features at least one mortise 2131 and an attachment receptacle 2140. The mortise 2131 is generally an aperture or depression around the periphery of the surface 2130. The mortise 2131 are generally for receiving a corresponding tennon for securing a pedestal to the top surface 2130. The attachment receptacle 2140 is generally a larger, central depression or aperture. The attachment receptacle 2140 is generally for receiving a corresponding extension 2141 from the bottom surface 2135 of a panel that has been stacked on the top surface.
The inner wall 2150. The inner wall 2150 is best viewed in FIG. 6. As seen in the figures, the inner wall 2150 may suitably be the internal portion of the panel's 2000 tubiform. As such, the inner wall 2150 generally extends internally between the foot 2110 and the underside 2135 of the surface 300. As further depicted in the figures, the inner wall 2150 ends at the bottom surface 2135. As further seen in FIGS. 5, 6, 7, and 8 the bottom surface 2135 generally defines a plane that is oblique to the plane of the foot surface 102 and the plane of the top surface 2130. The oblique angle has generally been identified by angle 2124. Preferably, the plane of the feet surface 2111 should suitably be below the plane of the bottom surface 2135.
FIG. 4 depicts two like panels coupled in stacked configurations. The panel 2100, as best seen in FIG. 6, features a receptacle which is generally defined by the inner wall 2150 and is adapted to femininely receive the surface 2130 end of a like panel 2100 until the bottom surface of the receiving panel (2135) interfaces with the top surface 2135 and the feet 2110 interface with the step 2122 of the inserting panel 2100. Referring still to FIG. 4 through 10, the orientation of the interface of the upper and lower surfaces 2130 and 2135 may be manipulated to change the slope of the top surface 2100 of the receiving panel 2100 with respect the feet plane 2111 of the lower panel 2100. The stated change in slope can be viewed by comparing the rotated pad 2000 of FIG. 4.
Referring first to FIG. 4, the upper and lower panels 2000 on the right are oriented with respect to one another whereby the angles 2124 of the panels are approximately alternate interior angles with respect to the panel interface, the top surface 2130 of the upper panel 2000, and the bottom surface 2135 of the bottom panel. (i.e., the surface 2130 of the upper panel and the bottom surface 2135 of the feet of the bottom panel are parallel and the concentric axes of the panels are aligned). The pedestal on the right of FIG. 4, can generally be obtained by identifying an origin point 0 on the pedestal of both panels and subsequently stacking the components thereby the origin 0 on the first panel 2000 is diametrically opposite (one-hundred and eighty degrees around the axis of the insertive panel 2000) to the origin 0 of the second panel. Further, the angle 2125 in this configuration is suitably zero degrees whereby the surface 2130 of the receiving panel is parallel with the feet surface 111 of the inserting panel 2100.
Referring now to the left side of FIG. 4, the receptive and insertive panels 2000 are oriented with respect to one another whereby the angles 2124 of the insertive and receptive components compound (i.e. have the same vortex point and share a common reference plane). The above described second configuration typically occurs when the origin point 0 on the first panel is aligned with the origin point 0 on the second panel as depicted on the left in FIG. 4. Further, the angle 2125 in this configuration is suitably the sum of angles 2124.
Preferably, rotating the first panel around the axis of the second panel along the interface of the top and bottom surfaces 2130, 2135 of the panels and between the above-identified configurations (i.e., rotating the origin of the first panel with respect to the axis of component 1B) will vary the size of the angle 2125 between the upper surface 2130 of the upper panel and the relative horizontal. Suitably, a maximum degree for the angle 2125 will be obtained in the identified left configuration of FIG. 4, a zero degree will be obtained as identified in the right configuration of FIG. 4, and an intermediate angle may be elected via positioning the origin of the first panel between zero or one hundred eighty degrees relative to the origin and axis of the second component. Referring again to FIGS. 9 and 10, in the present embodiment the angles 2124 are approximately 1 degree whereby the angle 2125 may vary from between 0 and two degrees. Subject thereto, the angles need not be limited to 1 degree, but rather it is preferable that the angles be in a range of about 0 to 5 degrees whereby the resulting angle 2125 may be selected to between a range of about 0 and 10 degrees depending on the circumstances.
The components of the pad 2000 being or composing a paver load bearing apparatus, slipresistant mechanism, noise dampening mechanism, and protective buffering to the substrate, should preferably be fashioned out of materials that are capable of these functions. As the weight of a paver may vary from extraordinarily heavy to very light, the materials which may be acceptable for fabricating components will typically vary according to the applicable paver to be supported thereon the pads. Depending on the circumstance, such materials will be readily known to one of skill in the art, and may include, without being limited to: plastics, polymers, PVC, polypropylene, polyethylene; metals; woods; ceramics; composites and other synthetic or natural materials whether molded, extruded, stamped or otherwise fabricated.
Similarly, the components of the assemblies being or composing a paver load bearing apparatus should preferably be dimensioned to a size that renders the assemblies capable of retaining a paver. As the size of a paver may vary from big to little, the physical dimensions of the components will typically vary according to the applicable paver to be supported thereon the apparatus. Depending on the circumstance, such dimensions will be readily known to one of skill in the art, and may include, without being limited to, a cap having an diameter spanning of 1.36 inches. The dependence of the size and dimensions of the component apply equally well to the other aspects and parts of this disclosure.
A slope compensation panel 2000 comprised of the above disclosed panels may be used to compensate for variations in the slope of the undersurface with regard to the leveling of a paver surface via a pedestal. For example, the method may comprise the following steps: obtaining a plurality of components comprising a structure having an undersurface and a top surface, said under surface configured to interface with the top surface of a like component; insertably coupling two of said components whereby the under surface of the receptive component interfaces with the top surface of the insertive component; manipulating the orientation of the insertive component with respect to the receptive component along the interface; and, providing a pedestal to the support surface.
As described to above, the disclosed assembly may be used for establishing a level paver surface over a sloped subsurface. FIG. 21 depicts a side view of the assembly 2000 and illustrates one mode establishing such leveled surface. Referring first to FIGS. 21A and 21B, the threaded insert 3200 suitably features a concave surface 3240 and the cap 3200 suitably features a convex surface 3230 whereby the slope of the paver support surface 3230 may be skewed in any direction relative to the plane of the foot 3110 of the base 3100 via sliding the convex surface 3230 of the cap 3200 along the concave surface 3240 of the insert 3200. In one embodiment, the paver support surfaces 3210 of four assemblies 4000 positioned at the four corners of a square paver will self level with respect to one another under the weight of the pavers installed thereon the assemblies 2000.
FIGS. 11 and 12 depict a plurality of trays 7000 installed on top of a plurality of paver pedestals. FIG. 13 is a perspective view of a tray 7000, which is an intermediate paver support surface. FIG. 14 is a top view of the tray 7000 of FIG. 13. In operation, a tray 7000 may be provided to a paver pedestal in the manner of a large paver and as shown in FIGS. 11 and 12 and small pavers deposited thereon in an array. In an alternate embodiment, the tray 7000 may be placed directly on the subsurface to provide a larger footprint for said small pavers.
Referring to FIG. 13, the tray 7000 is generally square and defined by a frame 7100 and a lattice 7200 having a plurality of spaces. As shown in FIGS. 13 and 14, the tray 7000 features a tubing track 7300 and all of the spaces in the lattice 7200 may define an aperture through the tray 7000 except the center space hexagon 7310 (See the shaded portion of FIG. 14). In one embodiment, the frame 7100 has holes or other apertures in its corner for securement to a pedestal as described in U.S. Pat. No. 7,140,156 (issued Nov. 28, 2006). As discussed later, each corner of the tray 7000 features a slot for receiving a locking disk or a locking slider (see FIG. 19).
It should be noted: although the locking tray 7000 is depicted as a square, any number of suitable shapes may be used. Such shapes will be known by those of skill in the art, and may include, but should not be limited to, triangle squares, circles, ovals, rectangles and other polygonal shapes. Also, the tray should be constructed of suitable material. Such materials will be readily known to one of skill in the art, and may include, without being limited to: plastics, polymers, PVC, polypropylene, polyethylene; metals; woods; ceramics; composites and other synthetic or natural materials whether molded, extruded, stamped or otherwise fabricated. Finally, it should further be noted that the dimensions of the tray 7000 will vary with the size of the paver to be retained by the pedestal. In particular, the height of the projections may vary depending on the thickness of a paver, e.g. in a range of about 0 to 100 inches.
In a preferred embodiment, the tray 7000 may be used to provide a heat exchanger to a paver 10 for heating or cooling a paver surface. FIG. 15 is an exploded view of a tray with a heat exchange configuration. FIG. 16 is a side view of the exploded tray 7000 configuration. As shown, insulation 7400 may be provided to the bottom of the frame 7100 and secured to the tray 7000 via a screw with large threads for gripping the insulation and retaining the insulation against the tray 7000. Referring to FIG. 18, the insulation 7400 is a pad with protrusions 7402 that insert into the apertures of the lattice. Therefore, the shape of the protrusions will match the shape of the apertures. An aluminum or other heat conducting metal plate 7500 with tubing lanes 7502 may suitably be positioned on top of the tray so that the tubing lanes are disposed within the tubing track 7300 of the tray 7000 (see FIG. 19). Tubing (not shown) may be provided through the tubing lanes 7502 and connected to a hot or cold water source and discharge. Finally a paver 10 may be positioned above the tubing and aluminum plate.
When constructed as shown FIGS. 15 and 16, the tray 7000 operates as a heat exchanger for the paver. For cooling a paver surface, cool water may be provided to the tubing so that heat may be conducted through the paver surface, along the heat conducting plate and into the water. For heating a paver surface, hot water may be provided to the tubing for the opposite heat flow. Suitably, the insulation keeps heat from being lost below the tray 7000.
Although water through tubing is described as the heat transfer mechanism, in an alternate embodiment, a refrigeration unit may be applied to the tray. In a preferred embodiment, the refrigeration unit is similar to the one disclosed in U.S. Pat. Pub. No. 2012/0298331 (published Nov. 29, 2012). In a preferred embodiment, the refrigeration will comprise an aluminum plate with capillary heat exchangers, wherein the plate features male inserts that will register in the apertures of tray. In other words, the system may be outfitted with a heat exchanging aluminum plate or heat exchanging panel that will fit and align with the hexagonal structures of the tray.
FIGS. 20 and 21 are respectively a view of a locking disk 5000 for securing tiles and an environmental view of the same. As shown in FIG. 20, the disk is circular and features a screw for anchoring the disk 5000 to a pedestal. As shown, the disk 5000 suitably features a break-away portion 5100, with perforation so that said portion 5100 may be broken off or folded away. In general, the disk 5000 may be inserted into corner slots of four adjacent tiles and secured to a pedestal, as shown in FIG. 21. Suitably, the disk 5000 feature indicia so that a user may, by looking between two adjacent tiles, identify when the disk is properly positioned. In one embodiment, the disk may feature teeth for a screwdriver (Phillips or flat head) so that the disk 5000 can be turned when in installed between pavers. A screw may be provided through the center of the disk for anchoring the disk to the pedestal. When the break-away portion of the disk is broken, bent or folded along the perforations, the locking disk suitably operates like the anchoring washer disclosed by U.S. Pat. No. 8,302,356 (issued Nov. 6, 2012), and that patent is hereby incorporated by reference. In a preferred embodiment, the disk 5000 is constructed of plastic.
Instead of a locking disk or anchoring pavers or tiles to the support surface of a pedestal, sliding attachment may be used for that purpose. FIGS. 22 through 25 respectively illustrate perspective, alternate perspective, top, and side views of a locking slider attachment 6000 for a paver upon surface of a pedestal. Referring to these figures, the attachment 6000 is generally a disc adapted for placement within an attachment receptacle of a pedestal's paver support surface whereby the disc and pedestal surface establish a paver support plane. The attachment 6000 is preferably retained within the receptacle via the locking means 6100 deflectively inserting into an aperture until its nibs snap into restrictive interface with the rim of the aperture for restricting the removal of the attachment 6000. As seen in FIGS. 22 through 25 the attachment features projections 6200 that operate to divide the surface 300 into evenly spaced paver receptacles whereby pavers provided to the pedestal may be uniformly oriented and spaced. For example, a paver may be supported above a subsurface positioning a pedestal on a subsurface; installing the attachment 6000 on the pedestal's support surface in the manner disclosed above, rotating the attachment 6000 until the orientation of the projections 6200 align with planned paver surface, and providing a corner of the paver to the surface support surface whereby the sides of the paver abut the projections 6200. See also FIG. 26 wherein the depicted pavers 10 are supported, spaced, and oriented by a component fitted with the attachment 6000. In a preferred embodiment, the projections 6200 define a spacer cross 6400 for dividing the paver support surface of a pedestal into quadrants.
Referring now to FIG. 26, a slider 6300 may suitably be positioned on the projections 6200 so that the slider may suitably be provided to a slot in a tray corner whereby the tray is anchored to the pedestal. Wither reference to FIGS. 22 and 23, the slider 6300 may be slidable between three locations: (1) a first side of the spacer cross 6400 (FIG. 23); (2) the center of the spacer cross 6400 (FIG. 22); and (3) the opposite side of the spacer cross 6400 (opposite of FIG. 23). Referring again to FIG. 26, two pavers may be provided to the first side of the paver cross 6400, the slider slid into the first position, two pavers may be placed on the other side of the paver cross 6400 and the slider 6300 slid to the center position whereby the pavers are anchored to the pedestal (FIG. 26).
It should be noted that the dimensions of the projections 6200, slider 6300 and spacer cross 6400 will vary depending on the desired paver spacing for the planned paver surface. It should be noted: although the locking means is depicted as a projection with a nib for restrictive interaction with an aperture rim, any number of suitable locking means may be used. Such locking means will be known by those of skill in the art, and may include, but should not be limited to, snaps, buttons, bolts, screw and nut mechanisms, and the like (e.g., a screw projecting downward for threaded entry into the aperture 117). Such materials will be readily known to one of skill in the art, and may include, without being limited to: plastics, polymers, PVC, polypropylene, polyethylene; metals; woods; ceramics; composites and other synthetic or natural materials whether molded, extruded, stamped or otherwise fabricated. Finally, it should further be noted that, the dimensions of the attachment 6000 will vary with the size of the paver to be retained by the pedestal. In particular, the height of the projections may vary depending on the thickness of a paver, e.g. in a range of about 0 to 20 inches.
An apparatus comprised of an above disclosed component may be used to compensate for variations in the slope of the undersurface with regard to the leveling of a paver surface. It should be noted that FIGS. 1 through 26 and the associated description are of illustrative importance only. In other words, the depiction and descriptions of the present invention should not be construed as limiting of the subject matter in this application. Additional modifications may become apparent to one skilled in the art after reading this disclosure.
The following disclosure describes embodiments of assemblies of components for facilitating the elevated and leveled placement of a paver array onto a subsurface. Suitably, the disclosed assemblies may be apparatus for supporting a paver surface or may interact with assembly components for establishing an elevated and slope adjusted surface. Yet still, the assemblies may suitably incorporate a riser to produce an apparatus for elevating and leveling a paver surface. The disclosed assemblies may receive attachments for orienting and spacing an array of pavers to be supported by the assemblage. Other embodiments of the present disclosure may be methods of establishing a paver surface using the assemblies. The details of the preferable assemblies are best disclosed by reference to FIGS. 27A through 55D.
FIGS. 27A and 27B depict a first embodiment of a pedestal or a assembly 100 for facilitating the elevated and leveled placement of a paver array onto a substrate. FIG. 27A is a perspective view of the pedestal assembly 100 and FIG. 27B is an exploded view of the same. As seen in the figures pedestal the assembly 100 comprises: a base 110; a cap 120; a key 130; and, a tile spacer 140.
FIGS. 28A through 28E depict different views of a preferable embodiment of the base 110 component of the apparatus 100 depicted in FIGS. 27A and 27B. Specifically, FIGS. 28A through 28E respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile view of the base 110. As can be seen in the referenced drawings, the base is generally a truncated cylinder and may comprise: a foot 111; a support cylinder 112; a riser socket 113 around the cylinder; a concave surface 114 defining the top of the cylinder 112; and a key socket 115 through the concave surface 114 along the axis of the cylinder 112.
FIGS. 29A through 29E depict different views of a preferable embodiment of the cap 120 component of the apparatus 100 depicted in FIGS. 27A and 28B. Specifically, FIGS. 29A through 29E respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile view of the cap 120. As can be seen in the referenced drawings, the cap 120 is generally a disc with a convex surface on its bottom side. Still referring to FIGS. 29A through 29E, the cap 120 may comprise: a paver support surface 121; a cylinder 122 extending from the bottom of the paver support surface 121; a convex surface 123 defining the bottom of the cylinder 122; a tile spacer receptacle 124 that is coaxial to the tile support surface 121; and, a key socket access hole 125 through the convex surface 114 along the axis of the cylinder 122.
FIGS. 30A through 30C depict different views of a preferable embodiment of the key 130 component of the apparatus 1000 depicted in FIGS. 1A and 1B, and 17A-29E. Specifically, FIGS. 30A through 30C respectively depict a top perspective, bottom perspective, and side profile view of the key 130. As can be seen in the referenced drawings, the key 130 is generally an elongated x-shaped member 131 with a flange 132. Referring to FIG. 30A, the elongated x-shaped member 131 features locking lugs 1311 at its lower end and the flange features a coaxial wrench socket 1321.
FIGS. 31A through 31E depict different views of a preferable embodiment of the tile spacer 140 component of the apparatus 100 depicted in FIGS. 27A and 27B. Specifically, FIGS. 31A through 31E respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile view of the spacer 140. As can be seen FIG. 31, the spacer 140 is generally a disc that features projections 141 that operate to divide the paver support surface 123 of the cap into evenly spaced paver receptacles whereby pavers provided to the assembly 100 may be uniformly oriented and spaced.
FIG. 27B shows a preferable method for assembling the assembly 100. First, the base 110 may be positioned so that the bottom side of the foot 111 interfaces with a subsurface and wherein the cylinder 112 extends outwardly and transversely relative to a plane of the subsurface. Second, the cap 120 may be positioned on top of the cylinder 112 of the base 110 so that the concave surface 114 of the base interfaces with the convex surface 123 of the cap 120 and wherein the key socket 115 of the base 100 is located within the key socket receptacle or access hole 125. Third, the x-shaped member 131 of the key 130 may be inserted through the key socket receptacle 125 and into the key socket 115 until the locking teeth 115 inside the key socket 115 interact with the locking lug 131 of the key 131 so that: (1) the key is retained inside the key socket 115; and (2) the cap 120 is movably slidably and/or rotatably) retained between the flange 132 of the key 132 and the concave surface 114 of the base 110. Finally, the tile spacer 140 may be provided to the spacer receptacle 124 of the cap 120 whereby the spacer 140 surface and the support surface 123 of the cap 120 generally form a plane.
Referring to FIG. 27B, a paver may be supported above a subsurface via: positioning an assembly 100, foot 111 down, on the subsurface; rotating the cap 120 around the key 130 until the orientation of the projections 141 of the spacer 140 align with a planned paver surface; and providing a corner of the paver to the paver support surface 123 whereby the sides of the paver abut the projections 141. See FIGS. 55A-D wherein the depicted pavers 10 are supported, spaced, and oriented by an assembly 100 with projections 141.
It should be noted that although the spacer 140 is depicted with four projections 141 for dividing the surface 123 into quadrants, the attachment may feature less or more projections to accommodate the orientation and spacing of non-square pavers. It should further be noted that the projections 141 may feature perforations (not shown) whereby the projections 141 may be individually removed from the spacer 140. For instance, two of the four projections 141 may be removed from the attachment whereby the side of a square paver, instead of its corner, may be received by the paver support surface 124 of the cap 120. Finally: the dimensions of the assembly 100 will vary with the size of the paver to be retained by the paver support surface 123. In particular, the height of the projections may vary depending on the thickness of a paver, e.g. in a range of about 0 to 20 inches.
Referring still to FIG. 27A-B, the foot 111 of is adapted to support the assembly 100 on a substrate or subsurface. This said, there may be instances where the substrate may be sensitive and require a larger footprint than that provided by the foot 111. For instance, the substrate may feature a waterproofing means that may be punctured by the weight of a paver on the assembly 100. In such a instance, the foot print of the foot 1110 may be supplemented with a buffer 150 as best depicted in FIGS. 31A, through 31E, which respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile view of the buffer 150. Referring to FIGS. 32A and 32E, the buffer 150 may generally be a disc with an upward projection 151 of slightly larger plan than the plan of foot 111 of the assembly whereby the foot 111 may be retained therein and where the disc of the buffer 150 distributes the footprint of the assembly 100 over a eider area. In one embodiment, the underside of the foot 111, as seen in FIG. 28D, features mortises 1111 which may cooperate with tenon 152, shown in FIG. 32A, so that the assembly may be positioned on the buffer 150 with greater stability. Other features of the buffer 150 will be set forth in greater detail below.
As alluded to above, the disclosed assembly may be used for establishing a level paver surface over a sloped subsurface. FIG. 33 depicts a side view of the assembly 100 and illustrates one mode establishing such leveled surface. Referring first to FIGS. 33, 28A and 29E, the base 110 may suitably feature a concave surface 114 and the cap 120 may suitably feature a convex paver support surface 123 whereby the slope of the paver support surface 123 may be skewed in any direction relative to the plane of the foot 111 of the base 110 via sliding the convex surface 123 of the cap 120 along the concave surface 114 of the base 110. In one embodiment, the paver support surfaces 123 of four assemblies 100 positioned at the four corners of a square paver will self level with respect to one another under the weight of the pavers installed thereon the assemblies.
FIGS. 34A through 34C depict a second embodiment of a pedestal assembly 200 for facilitating the elevated and leveled placement of a paver array onto a subsurface. FIG. 34A is a side elevation view of the assembly 200 in a first configuration; FIG. 34B is a side elevation view of the assembly 200 in a second configuration; and FIG. 34C is an exploded view of the assembly 200. As seen in the figures the assembly 200, like the assembly of FIGS. 27A and 27B comprises: a base 110; a cap 120; a key 130; and, a tile spacer 140. The structure and operability of those components are the same as described above in connection with the first embodiment of the assembly 100. Unlike the assembly 100 of FIGS. 27A and 27B, the assembly 200 further comprises a female threaded collar 210; and a male threaded insert 220.
FIGS. 35A through 35E depict different views of a preferable embodiment of the threaded collar 210 component of the apparatus 200 depicted in FIGS. 34A through 34C. Specifically, FIGS. 35A through 35E respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile/of the threaded collar 210. As can be seen in the referenced drawings, the threaded collar 210 is generally a truncated tubiform with; a grip flange 211; female threads 212 on the inside of its tubiform; and a foot 213.
FIGS. 36A through 36E depict different views of a preferable embodiment of the threaded insert 220 component of the apparatus 200 depicted in FIGS. 34A through 34C. FIGS. 36A through 36E respectively depict a top perspective, bottom perspective, top plan bottom plan, and side profile view of the threaded insert 220. As can be seen in the referenced drawings, the threaded insert is generally a truncated cylinder and may comprise: a foot 221; a male threads 222 on the outside surface of its cylinder shape; a concave surface 224 defining the top of the cylinder; and a key socket 225 through the concave surface 224 along the axis of the cylinder.
FIG. 34C shows a preferable method for assembling pedestal assembly 200. First, the base 110 may be positioned so that the bottom side of the foot 111 interfaces with a subsurface and wherein the cylinder 112 extends outwardly and transversely relative to a plane of the subsurface. Second, a riser 420 (e.g., a pipe section) may be positioned within the riser socket 113 of the base 110. Third, the foot 213 of the threaded collar 210 may be provided to the top of the riser 420 so that the foot 213 of the threaded collar 410 is positioned inside of the riser 420. Fourth, the foot 221 of the threaded insert 220 may be provided to the top of the threaded collar 210 so that the threads 212 of the collar 210 and the threads 222 of the insert 220 cooperate to drive the insert 220 to within the tubiform of the collar 410. Fifth, the foot 221 of the threaded insert 220 may be provided to the top of the threaded collar 210 so that the threads 212 of the collar 210 and the threads 222 of the insert 220 cooperate to drive the insert 220 to within the tubiform of the collar 210. Sixth, the cap 120 may be positioned on top of the threaded insert 220 so that the concave surface 224 of the insert 220 interfaces with the convex surface 123 of the cap 120 and wherein the key socket 225 of the insert 220 is located within rue key socket receptacle 125 of the cap 120. Seventh, the x-shaped member 131 of the key 130 may be inserted through the key socket receptacle 125 and into the key socket 225 until the locking teeth 2251 inside the key socket 225 interact with the locking lug 1311 of the key 131 so that: (1) the key is retained inside the key socket 225; and (2) the cap 120 is movably (e.g., slidably and/or rotatably) retained between the flange 132 of the key 132 and the concave surface 224 of the threaded insert 220. Finally, the tile spacer 140 may be provided to the spacer receptacle 124 of the cap 120 whereby the spacer 140 surface and the support surface 123 of the cap 120 generally form a plane.
Referring to FIGS. 34A and 34B, a paver may be supported above a subsurface via: positioning an assembly 200, foot 111 down, on the subsurface; rotating the cap 120 around the key 130 until the orientation of the projections 141 of the spacer 140 align with a planned paver surface; and providing a corner of the paver to the paver support surface 123 whereby the sides of the paver abut the projections 141.
As described above, the disclosed assembly may be used for establishing a level paver surface over a sloped subsurface. FIG. 37 depicts a side view of the assembly 200 and illustrates one mode establishing such leveled surface. Referring first to FIGS. 36A and 29E, the threaded insert 220 suitably features a concave surface 224 and the cap 120 suitably features a convex surface 123 whereby the slope of the paver support surface 123 may be skewed in any direction relative to the plane of the foot 111 of the base 110 via sliding the convex surface 123 of the cap 120 along the concave surface 224 of the insert 220. In one embodiment, the paver support surfaces 121 of four assemblies 200 positioned at the four corners of a square paver will self level with respect to one another under the weight of the pavers installed thereon the assemblies 200.
In some instances, the caps 120 of a four assembly system cannot, without more than sliding the convex surface 123 of the cap 120 along the concave surface 224 of the insert 220, be skewed enough in the applicable direction to accomplish a level surface of a square paver because the slope of the under surface may be too drastic. In such instances, a level paver surface may be accomplished via raising or lowering one or more of the paver support surface 123 of the pedestal assemblies 200 relative to one or more of the paver support surface 123 of the other pedestal assemblies 200. In one embodiment, such raising or lowering of the paver support surface 123 of an assembly 200 may be accomplished via: (1) removing the paver spacer 140 from the assembly cap 120 of the assembly 200; (2) inserting a wrench into the wrench socket 1321 of the key; (3) griping the flange grip 211 of the collar 210; and (3) torquing the wrench so that the key 130 turns the insert 220 whereby the threads of the insert 220 and collar 210 interact to drive the insert further into or out of the tubiform of the collar 210.
In one embodiment, a plurality of assemblies 100, 200 may be used to support a paver surface. Frequently, the plurality of assemblies 100, 200 must be fixedly positioned at specific locations relative to one another for supporting the paver surface. To facilitate such positioning, an arm 230 may be provided that connects to two pedestal assemblies whereby their relative positions are so fixed. Such an arm 230 is depicted in FIGS. 38A through 38E. Specifically, FIGS. 38A through 38E respectively depict a top perspective, bottom perspective, top plan, bottom plan, and side profile view of the arm 230. Generally referring to the figures, the arm is comprised of retractable extensions with tenon 231 on either side. FIG. 39 is an environmental view of the arm 230 used for fixing the space between two pedestal assemblies 100, 200. As shown the figure, the tenon 231 of the arm 230 may be inserted into mortises 2112 on the upperside of the foot 111, 211 of the bases 110, 210 of two adjacent pedestal assemblies 100, 200.
The components of the pedestal assemblies 100, 200, being or composing a paver load bearing apparatus, should preferably be fashioned out of materials that are capable of supporting the weight of a paver. As the weight of a paver may vary from extraordinarily heavy to very light, the materials which may be acceptable for fabricating the components will typically vary according to the applicable paver to be supported thereon the pedestal assemblies 100, 200. Depending on the circumstance, such materials will be readily known to one of skill in the art, and may include, without being limited to: plastics, polymers, PVC, polypropylene, polyethylene; metals; woods; ceramics; composites and other synthetic or natural materials whether molded, extruded, stamped or otherwise fabricated.
Similarly, the components of the assemblies 100, 200 being or composing a paver load bearing apparatus should preferably be dimensioned to a size that renders the assemblies 100, 200 capable of retaining a paver. As the size of a paver may vary from big to little, the physical dimensions of the components will typically vary according to the applicable paver to be supported thereon the apparatus. Depending on the circumstance, such dimensions will be readily known to one of skill in the art, and may include, without being limited to a cap having an diameter spanning of 1.36 inches. The dependence of the size and dimensions of the component apply equally well to the other aspects and parts of this disclosure.
FIGS. 40 and 41 depict a third embodiment of a pedestal assembly 300 for facilitating the elevated and leveled placement of a paver array onto a substrate. FIG. 40 is a side view of the pedestal assembly 300 and FIG. 41 is an exploded view of the same. As seen in the figures, the assembly 300 comprises: a base 310; a threaded insert 350, and a cap 320.

FIGS. 45A through 45C depict different views of a preferable embodiment of the threaded insert 350 component of the apparatus 300 depicted in FIGS. 40 through 41. Actually, FIGS. 45A through 45C respectively depict a top perspective, top plan, and side profile views of the threaded insert 350. As can be seen it the referenced drawings, the threaded insert is generally a truncated cylinder and may comprise: a foot 351; a male threads 352 on the outside surface of its cylinder shape; a concave surface 354 defining the top of the cylinder; and a key 355 extending coaxially from the concave surface 354 along the axis of the cylinder 350.
FIGS. 40 through 45C show a preferable method for assembling the assembly 300. First, the base 310 may be positioned so that the bottom side of the foot 311 interfaces with a subsurface extends outwardly and transversely relative to a plane of the subsurface. Second, the foot 351 of the threaded insert 350 may be provided to the top of the base 310 so that the threads 312 of the base 310 and the threads 352 of the insert 350 cooperate to drive the insert 350 to within the tubiform of the base 310. Fourth, the cap 320 may be positioned on top of the threaded insert 350 so that the concave surface 354 of the insert 350 interfaces with the convex surface 323 of the cap 320 and wherein the key 355 of the insert 350 is located within the key socket access hole 325 of the cap 320 so that: (1) the key is retained inside the key socket 325; and (2) the cap 320 is movably (e.g., slidably and/or rotatably) retained between the flange of the key 355 and the concave surface 354 of the threaded insert 350.
Referring to FIGS. 40 through 45C, a paver may be supported above a subsurface via: positioning pedestal assembly 300, foot 311 down, on the subsurface; and providing a corner of the paver to the paver support surface 321 whereby the sides of the paver abut. It should be noted that the dimensions of the assembly 300 will vary with the size of the paver to be retained by the paver support surface 321. In particular, the height of the projections may vary depending on the thickness of a paver, e.g. in a range of about 0 to 20 inches. It should be also noted that, now, and throughout the application the terms “top” and “bottom” or “lower” and “upper”, or any other orientation defining term should in no way be construed as limiting of the possible orientations of the assembly 300 (i.e., the assembly may be positioned sideways, or in reversed vertical orientations even though the specification refers to a “top” and “bottom” parts).
As described to above, the disclosed assembly may be used for establishing a level paver surface over a sloped subsurface. FIGS. 46A and 46B depict side cross-section views of the assembly 300 and illustrate one mode establishing such leveled surface. Referring first to FIGS. 46A and 46B, the base 310 suitably feat concave surface 314, and the cap 320 suitably features a convex surface whereby the slope of the paver support surface a skewed in any direction relative to the plane of the foot 311 of the base 310 via sliding the convex surface 323 of the cap 320 along the concave surface 314 of the base 310. In one embodiment, the paver support surfaces 321 of four assemblies 300 positioned at the four corners of a square paver will self level with respect to one another under the weight of the pavers installed thereon the assemblies.
FIGS. 47A through 47B depict a fourth embodiment of a pedestal assembly 400 for facilitating the elevated and leveled placement of a paver array onto a subsurface. FIG. 47A is a side view of the pedestal assembly 400; FIG. 47B is an exploded side view of the pedestal assembly 400 of FIG. 47A. As seen in the figures, the pedestal assembly 400, like the pedestal assembly 300 of FIGS. 40 and 41, comprises: a base 310; a threaded insert 350, and a cap 320. The structure and operability of those components are the same as described above in connection with the third embodiment of a pedestal assembly 300 shown in FIGS. 40 and 41. Unlike the assembly 300 of FIGS. 40 and 41, the assembly 400 further comprises a female threaded collar 410 and a riser 420.
FIGS. 48A through 48C depict different views of a preferable embodiment of the threaded collar 410 component of the apparatus 400 depicted in FIGS. 46A through 46B. Specifically, FIGS. 48A through 48C respectively depict a top perspective, side profile view, and bottom plan view of the threaded collar 410. As can be seen in the referenced drawings, the threaded collar 410 is generally a truncated tubiform a grip flange 411; female threads 412 on the inside of its tubiform; and a foot 413.
FIG. 47A through FIG. 48C show a preferable method for assembling the assembly 400. First, the base 410 may be positioned so that the bottom side of the foot 311 interfaces with a subsurface and extends outwardly and transversely relative to a plane of the subsurface. Second, a riser 420 (e.g., a pipe section) may be positioned within the riser receptacle 313 of the base 310. Third, the foot 413 of the threaded collar 410 may be provided to the top of the riser 420 so that the foot 413 of the threaded collar 410 is positioned inside of the riser 420. Fourth, the foot 351 of the threaded insert 350 may be provided to the top of the threaded collar 410 so that the threads 412 of the collar 410 and the threads 352 of the insert 350 cooperate to drive the insert 350 to within the tubiform of the collar 410. Fifth, the cap 320 may be positioned on top of the threaded insert 350 so that the concave surface 354 of the insert 350 interfaces with the convex surface 323 of the cap 320 and wherein the key 355 of the insert 350 is located within the key socket access hole 325 of the cap 320 and wherein the cap 320 is movably (e.g., slidably and/or rotatably) retained between the flange of the key 325 and the concave surface 354 of the threaded insert 320. Finally, the tile spacer 140 may be provided to the spacer receptacle 324 of the cap 320 whereby the spacer 140 surface and the support surface 321 of the cap 320 generally form a plane.
Referring to FIGS. 47A and 47B, a paver may be supported above a subsurface via: positioning an assembly 400, foot 311 down, on the subsurface; rotating the cap 320 around the key 325 until the orientation of the projections 141 of the spacer 140 align with a planned paver surface; and providing a corner of the paver to the paver support surface 321 whereby the sides of the paver abut the projections 141.
As described to above, the disclosed assembly may be used for establishing a level paver surface over a sloped subsurface. FIG. 47A depicts a side view of the pedestal assembly 400 and illustrates one mode establishing such leveled surface. Referring first to FIGS. 47A and 47B the threaded insert 350 suitably features a concave surface 354 and the cap 320 suitably features a convex surface 323 whereby the slope of the paver support surface 321 may be skewed in any direction relative to the plane of the foot 311 of the base 310 via sliding the convex surface 323 of the cap 320 along the concave surface 354 of the insert 320. In one embodiment, the paver support surfaces 321 of four assemblies 400 positioned at the four corners of a square paver will self level with respect to one another under the weight of the pavers installed thereon the assemblies 200.
In some instances, the caps 320 of a four assembly 300, 400 system cannot, without more than sliding the convex surface 323 of the cap 320 along the concave surface 354 of the insert 350, be skewed enough in the applicable direction to accomplish a level surface of a square paver because the slope of the under surface may be too drastic. In such instances, a level paver surface may be accomplished via raising or lowering one or more of the paver support surface 321 of the assemblies 300/400 relative to one or more of the paver support surface 321 of the other assemblies 300/400. In one embodiment, such raising or lowering of the paver support surface 321 of an assembly 300/400 may be accomplished via: (1) removing the paver spacer from the assembly cap 320 of the pedestal assembly 300; (2) inserting a wrench into the wrench socket 1321 of the key; (3) griping the grip flange 411 of the collar 410; and (3) torquing the wrench so that the key 130 turns the insert 350 whereby the threads of the insert 350 and collar 410 interact to drive the insert further into or out of the tubiform of the collar 410.
As set forth above, the pavers supported by disclosed pedestal assemblies 100-400 may suitably support pavers of various sizes and shapes. In order to account for such paver variation, multiple embodiments of the top surface of the tile spacer 140 may be provided. FIG. 49A through 49C are views of a top surface of a tile spacer 240, wherein tiles are locked in place via a vise plate. FIG. 50 is a view of a top surface of a spacer 340, wherein a support beam is disposed between two curved walls. FIGS. 51A and 51B are respectively a view of an anchoring washer for securing wooden tiles and an environmental view of the same. FIGS. 52A and 52B are respectively views of a top surface of a spacer 440 and environmental views of the same. FIGS. 53A and 53B are respectively views of a top surface of an adjustable pipe riser spacer 540.
In one embodiment, a plurality of assemblies 300, 400 may be used to support a paver surface. Frequently, the plurality of assemblies 300, 400 must be fixedly positioned at specific locations relative to one another for supporting the paver surface. To facilitate such positioning, an arm may be provided that connects to two pavers whereby their relative positions are so fixed. Such an arm may be a pipe section provided between two pipe receptacles on the foot of a base 310 of an assembly. One embodiment, a pipe receptacle 500 is provided in FIG. 54. Generally referring to the figures, a pipe may be provided between two pipe receptacles to establish an arm. The arm may suitably be fixedly retained within the pipe receptacles via providing a screw through the side of the pipe receptacle and into a retained pipe.

The components of the assemblies 100-400, being or composing a paver load bearing apparatus, should preferably be fashioned out of materials that are capable of supporting the weight of a paver. As the weight of a paver may vary from extraordinarily heavy to very light, the materials which may be acceptable for fabricating the components will typically vary according to the applicable paver to be supported thereon the assemblies 100-400. Depending on the circumstance, such materials will be readily known to one of skill in the art, and may include, without being limited to: plastics, polymers, PVC, polypropylene, polyethylene; metals; woods; ceramics; composites and other synthetic or natural materials whether molded, extruded, stamped or otherwise fabricated.
Similarly, the components of the assemblies 100-400 being or composing a paver load bearing apparatus should preferably be dimensioned to a size that renders the assemblies 100-400 capable of retaining a paver. As the size of a paver may vary from big to little, the physical dimensions of the components will typically vary according to the applicable paver to be supported thereon the apparatus. Depending on the circumstance, such dimensions will be readily known to one of skill in the art, and may include, without being limited to a cap having an diameter spanning of 1.36 inches. The dependence of the size and dimensions of the component apply equally well to the other aspects and parts of this disclosure
An apparatus comprised of an above disclosed component may be used to compensate for variations in the slope of the undersurface with regard to the leveling of a paver surface. It should be noted that FIGS. 27A through 55D and the associated description are of illustrative importance only. In other words, the depiction and descriptions of the present invention should not be construed as limiting of the subject matter in this application. Additional modifications may become apparent to one skilled in the art after reading this disclosure.
