Description

2 FIELD OF THE INVENTION

This invention pertains generally to architectural pavers and more particularly to a paver hidden lock down system and methods.

3 BACKGROUND OF THE INVENTION

Paver tiles, for example, porcelain tiles, have many benefits as a finish material. The dense, fully vitrified body of the product makes it easy to clean and resists surface wear. For this reason porcelain tile is the top choice for owners and specifiers looking to clad high traffic interior and exterior floors in tile. Traditional method of porcelain tile installation is to glue the product down to a substrate. This standard thickness (9-12 mm thick) porcelain tile alone has very poor center load and tensile strength when not fully bonded to a suitable substrate.

Currently, the plaza deck, rooftop, and landscape paver market is dominated by 2-inch thick pressed concrete architectural pavers. These pavers are considered to be self-supporting and have about 2 to 3 inches of support by the pedestals (only under the corners) at the paver intersections. Thinner and lighter pavers can solve a great deal of problems associated with load on the structures and shallow deck profiles. Therefore, porcelain tile manufacturers have been working to enter this market. A recent trend in the tile industry is for many manufacturers to produce “extra thick” 20 mm (2 cm thick) (less than half the thickness of the concrete pavers) porcelain tiles that allegedly can be used without bonding to a substrate, so they are considered a “self-supporting” porcelain paver that can be supported in a similar manner as the 2-inch thick concrete paver. While the added thickness does provide some level of improved tensile strength, shock impact and very heavy loads may cause these “extra thick” pavers to shatter just like the traditional thinner tiles.

Even the proven industry accepted 2-inch thick concrete pavers break occasionally. Likewise, the porcelain pavers break occasionally. When concrete pavers break on pedestals they merely crack into large pieces. Once broken, the concrete pavers buckle and fall off the pedestal supports. The broken edges may be serrated but are rather dull and will not seriously slice the skin. That is, the broken concrete pavers pose little risk of injury. By contrast, when a porcelain paver breaks it shatters like non-tempered glass. Razor sharp edges and large daggers and shards are created, which can easily cut the skin and are dangerous.

6 DETAILED DESCRIPTION OF THE INVENTION

The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying Drawings, in which some, but not all embodiments of the presently disclosed subject matter are shown. Like numbers refer to like elements throughout. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the presently disclosed subject matter set forth herein will come to mind to one skilled in the art to which the presently disclosed subject matter pertains having the benefit of the teachings presented in the foregoing descriptions and the associated Drawings. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding thereof. It may be evident, however, that the novel embodiments can be practiced without these specific details. In other instances, well known structures and devices are shown in block diagram form in order to facilitate a description thereof.

The presently disclosed subject matter now will be described more fully hereinafter with reference to the accompanying Drawings, in which some, but not all embodiments of the presently disclosed subject matter are shown. Like numbers refer to like elements throughout. The presently disclosed subject matter may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Indeed, many modifications and other embodiments of the presently disclosed subject matter set forth herein will come to mind to one skilled in the art to which the presently disclosed subject matter pertains having the benefit of the teachings presented in the foregoing descriptions and the associated Drawings. Therefore, it is to be understood that the presently disclosed subject matter is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims.

The presently disclosed subject matter provides a composite, reinforced backing system to a paver, such as, for example, a porcelain paver. This backing provides strength, prevents broken tile from shattering/splintering and allows for a paver system to be connected together and thus prevents, as one advantage, vandalism (picking up and throwing of tiles) a common concern for commercial project specifiers.

The lock down system is a hidden lock down or tied down paver system. Paver intersections offer a unique locking mechanism that is hidden below the paver surface and accessed through the open joint that is created in all raised pedestal/floating paver systems. This feature prevents vandalism or tampering with the individual pavers. Porcelain pavers, for example, are very light (thus subject to being tampered with) compared to traditional 2″ thick concrete pavers typically used for pedestal systems. The locking feature also prevents the floating paver system from “creeping” or “migrating” across the edges of the installation. Wind uplift is another concern for specifiers in high wind zones (e.g., coastal areas and areas subject to tornados) and for urban installations above 5-6 stories high. The lock down system may potentially provide some element of wind uplift protection due to the pavers being tied together creating a “raft” of single pavers.

In some embodiments, the presently disclosed subject matter provides a paver hidden lock down system and methods. The presently disclosed paver lock down system and methods provide a paver safety net and tie down system. Namely, the paver lock down system provides a composite, reinforced backing system to a paver, such as, any standard 2-cm thick (or any other thickness) porcelain paver (any manufacturer), or any one or more of ceramic, concrete, natural stone (e.g., granite and/or slate), and/or any other self supporting paver. This reinforced backing system provides strength and allows for the paver system to be connected together. Because the pavers of the paver lock down system are connected together, vandalism of the tiles (picking up and throwing of tiles), which is a common concern for commercial project specifiers, can be prevented. Further, whereas conventional pavers, such as porcelain pavers, shatter when they break, which can create sharp edges and large daggers and shards, the presently disclosed paver lock down system prevents broken tile from shattering/splintering. By substantially reducing or entirely eliminating the risk of injury, product specifiers and end users will be more comfortable using pavers within the presently disclosed paver lock down system for their decks, balconies, roof top plazas, etc.

Referring now to FIG. 1 and FIG. 2 is a top down view and an underside view, respectively, of an example of the presently disclosed paver lock down system 100. The paver lock down system 100 includes an arrangement or array of paver assemblies 110 that are coupled or tied together at each corner by a paver spacer 130. In one example, each of the paver assemblies 110 includes a paver 112, for example, a standard 2-cm thick porcelain paver. On the back of the paver 112, a first strap 114 is arranged across one diagonal and a second strap 114 is arranged across the other diagonal of the paver 112. Then, a bonding layer 116, such as a fiber mesh and a resin, covers both the first and second straps 114 and preferably the exposed portions of the back of the paver 112. The bonding layer may be of any suitable materials, for example a fiber mesh and an epoxy resin. Other materials, such as fiberglass mesh or mating (and the like), and other resigns, such as fiberglass resin, polyester resin, adhesives, and the like, and/or combination of materials, capable of securing first and second straps 114 to the back of the paver 112 may be used as bonding layer 116.

More particularly, the first and second straps 114 preferably form an X pattern on the back of the back of the paver 112. In one example, the first and second straps 114 are about 1-inch wide nylon straps. The length is cut such that the ends of the straps 114 extend beyond the corners of the paver 112. In one example, the ends of the straps 114 extend in the range of about ⅝ of an inch beyond the corners of the paver 112. The bonding layer 116 is sized to substantially match the size of a backside of the paver 112. The straps 114 are preferably first placed on the back of the paver 112, followed by the bonding layer 116.

In one example, the straps 114 and the bonding layer 116 are applied to the back of the paver 112 via a layer of highly viscous resin, or other suitable adherent, coating, or the like. A hole 118 may be provided in each end of the straps 114, as shown in FIGS. 5A, FIG. 5B, FIG. 5C, and FIG. 5D. More details of a non-limiting example of a method of making the paver assemblies 110 are described hereinbelow with reference to FIG. 3. The straps 114 are used to fasten the paver assemblies 110 to the paver spacers 130 and thereby form the presently disclosed paver lock down system 100. More details of an example of a method of installing the presently disclosed paver lock down system 100 are described hereinbelow with reference to FIG. 9.

Referring now to FIG. 3 is a flow diagram of an example of a method 300 of forming the paver assembly 110 of the presently disclosed paver lock down system 100. The method 300 may include, but is not limited to, the following steps.

At a step 310, the paver 112, in its original packaging, may be removed from the original packaging and placed upside down on a work surface.

At a step 315, at the underside of each corner of the paver 112, a notch 120 is created by removing a small amount of material, at the tip of the corner of paver 112, for example using an angle grind to create a bevel, which creates an isosceles triangle of removed material. In one example, the notch 120 has a beveled angle of about 45 degrees from horizontal and is about 1 inch in length until flush with the back of paver 112. The base of the removed material from paver 112 may be about 1 ½ inches wide. In one example, about ½ inch of thickness of paver 112 remains between its top surface and the upper portion of the start of the beveled angle. This notch 120 allows for the locking mechanism to work, while still allowing the pavers 112 to lay flat. The above dimensions, measurements, and/or angles may vary ± depending on the exact dimensions of the paver(s).

At a step 320, if fiber mesh is used as part of the bonding layer 116, then the fiber mesh is cut to substantially match the size of the paver 112. In one example, if the paver 112 is 12 inches×12 inches (actually 11-¾″×11-¾″) then the fiber mesh is cut to 12 inches×12 inches.

At a step 325, the straps 114 are cut to length according to the size of the paver 112. In one example, if the paver 112 is 12 inches×12 inches (actually 11-¾″×11-¾″) then the straps 114 are cut to about 17-½ inches in length. In another example, if the paver 112 is 24 inches×24 inches (actually 23-½″×23-½″) then the straps 114 are cut to about 34-½ inches in length. In one example, the straps 114 are 1-inch wide nylon straps. It should be appreciated that the actual lengths the straps 114 are cut to may vary due to the actual sizing of the pavers varying greatly between manufacturers.

At a step 330, a highly viscous resin, e.g., epoxy resin, (or other suitable adherent, coating, or the like), is mixed and then applied to the back side of the paver 112. For example, a highly viscous resin is mixed and then placed in a small paint roller pan. Then, a roller (e.g. 4 inch roller) may be used to “paint” the resin onto the back of the paver 112. In such an example, the entire back of the paver 112 is coated with the resin to a thickness of about 10 millimeters.

At a step 335, while the resin is still wet, the straps 114 (e.g., 1-inch wide nylon straps) may be installed in an X pattern on the back of the paver 112, wherein the ends of the straps 114 extend beyond the corners of the paver 112.

At a step 340, more resin may be applied as needed over the straps 114 and over the back of the paver 112.

At a step 345, while the resin is still wet, the fiber mesh of bonding layer 116 is positioned over the straps 114 onto the back of the paver 112, wherein the edges of the precut fiber mesh substantially align with the edges of the paver 112.

At a step 350, the fiber mesh is worked into the wet resin to eliminate air bubbles and help ensure best contact to the resin. For example, using a large flat putty knife, the fiber mesh can be worked like wallpaper into the wet resin to eliminate air bubbles and help ensure best contact to the resin.

At a step 355, a final coating of resin can be applied over the entirety of the fiber mesh to complete the bonding layer 116. For example, a 4-inch roller can be used to apply the final coating of resin to the fiber mesh (see FIG. 2).

At a step 360, after the resin is cured, the ends of the straps 114 can be trimmed to their final length if needed and holes 118 may be formed in the ends of the straps 114. Alternatively, straps 114 may be pre-cut and the holes may be pre-formed. In one example, the holes 118 are about ⅛ of an inch in diameter (see FIG. 5A, FIG. 5B, FIG. 5C, and FIG. 5D). In one example, the ends of the straps 114 may extend in the range of about ⅝ of an inch beyond the corners of the paver 112.

Referring now to FIG. 4A and FIG. 4B is a top view and a bottom view, respectively, of an example of the paver spacer 130 of the presently disclosed paver lock down system 100. In this example, the paver spacer 130 is circular. However, the paver spacer 130 can be any suitable shape, such as circular, rectangular, square, and the like. Further, in this example, the paver spacer 130 is formed of plastic. However, the paver spacer 130 can be formed any rigid strong material, such as plastic, aluminum, stainless steel, and the like.

The paver spacer 130 includes a baseplate 132. A threaded nut 134 may be provided at about the center of the baseplate 132, wherein the threaded nut 134 may be embedded into the baseplate 132. Protruding upward from the surface of the baseplate are four tabs 136, as shown in FIG. 4A. The four tabs 136 are provided for setting the corners of the pavers 112 in relation to each other. Further, the four tabs 136 are used to set the spacing between the pavers 112 (see FIG. 8). Additionally, the four tabs 136 are provided for guiding the straps 114 onto the paver spacer 130 (see FIG. 5A, FIG. 5B, FIG. 5C, and FIG. 5D). In one example, tabs 136 may be about ⅛ of inch thick and in another example may be about 3/16 of an inch thick, and are about ¾ of an inch high. The threaded nut 134 may be provided for fastening the ends of the straps 114 to the paver spacer 130 via, for example, a screw (see FIG. 6A and FIG. 6B). The paver spacer 130 may further include a recessed portion 138. Recessed portion 138 is preferably sized and shaped to allow the space required for the ends of straps 114, for example, the ends of four straps 114 from four adjacent pavers, to stack on each other without lifting the corners of the paver 112 up, which could possibly creating a tripping hazard, unwanted stress on the paver 112 corner(s). The recessed portion 138 may be, in one example, about 1 inch square and about ⅛ inch deep. The combination and configuration of the recess portion 138, the paver spacer 130, and notch 120, there is sufficient room to bring the paver straps 114 together to be secured with securing mechanism 139, such as screw 142, washer 140 and nut 134.

Referring now to FIGS. 5A, FIG. 5B, FIG. 5C, and FIG. 5D are top views of the paver spacer 130 and a process of mating the straps 114 thereto (absent the paver 112). Namely, FIG. 5A shows the end of a first strap 114 aligned to the paver spacer 130 via one pair of tabs 136 and its hole 118 aligned with the threaded nut 134. FIG. 5B shows the end of a second strap 114 aligned to the paver spacer 130 via a different pair of tabs 136 and its hole 118 also aligned with the threaded nut 134. FIG. 5C shows the end of a first strap 114 aligned to the paver spacer 130 via a yet different pair of tabs 136 and its hole 118 also aligned with the threaded nut 134. FIG. 5D shows the end of a first strap 114 aligned to the paver spacer 130 via a still different pair of tabs 136 and its hole 118 also aligned with the threaded nut 134.

After the ends of the four straps 114 are positioned with respect to the paver spacer 130, FIG. 6A and FIG. 6B show a process of connecting the four straps 114 to the paver spacer 130 via a securing mechanism 139. Securing mechanism 139 may include one or more of washer 140, screw 142, threaded nut 134, and/or any other suitable mechanism for connecting the four straps 114 to the paver spacer 130. In one example, a washer 140 is placed atop the stack of four straps 114 at the holes 118, as shown in FIG. 6A. Next, for example, and as shown in FIG. 6B, a screw 142 is installed through the holes 118 in the four straps 114 and tightened into the threaded nut 134 (not visible).

Referring now to FIG. 7 is a plan view of an array of the paver assemblies 110 of the paver lock down system 100, wherein the paver assemblies 110 are connected together via the straps 114 to form a safety net. Connecting the straps 114 at each paver assembly 110 effectively ties all the paver assemblies 110 together, such that no paver assembly 110 can be moved or tampered with unless all lock down screws 142, for example, are removed for that paver assembly 110. FIG. 8 is a cross-sectional view of the joint between the paver assemblies 110 of the presently disclosed paver lock down system 100 and showing more details thereof. In particular, FIG. 8 shows a notch 120 at the underside of the corners of the pavers 112. The notch 120 is formed, for example, according to the step 315 of the method 300 of FIG. 3. FIG. 8 also shows an open joint 150 between the two paver assemblies 110. The open joint 150 allows access to the center of the paver spacer 130 for fastening the straps 114 thereto. Open Joint 150 is preferably created by tabs 136 of paver spacer 130, and in one example may be about ⅛ of inch wide, and in another example may be about 3/16 of an inch wide.

Certain pavers, for example porcelain pavers, are very light (thus subject to being tampered with) compared with the traditional 2-inch thick concrete pavers typically used for pedestal systems. Referring again to FIG. 1 through FIG. 8, the presently disclosed paver lock down system 100 provides a hidden lock down or tied down feature (i.e., the straps 114 fastening to the paver spacers 130) for a paver system 100. Namely, the paver 112 intersections of the paver lock down system 100 offer a unique locking mechanism that is hidden below the paver 112 surface and accessed through the open joint 150 that is created in all raised pedestal/floating paver systems. This locking mechanism prevents vandalism or tampering with the individual pavers. The locking mechanism also prevents the floating paver system from “creep” or “migration” across the edges of the installation.

Referring now to FIG. 9 is a flow diagram of an example of a method 900 of installing the presently disclosed paver lock down system 100. FIG. 1 and FIG. 10 through FIG. 24 will be referred to in the method 900. By way of example, the method 900 describes the installation of a 2×2 array of paver assemblies 110, such as the 2×2 array of paver assemblies 110 shown in FIG. 1. However, it is understood that the method 900 can be applied generally to any configuration and any number of paver assemblies 110. The method 900 may include, but is not limited to, the following steps.

At a step 910, the first paver assembly 110 and four paver spacers 130 are provided. Then, four paver spacers 130 are aligned to the four straps 114 at the four respective corners of the first paver assembly 110. This step is shown pictorially in FIG. 10 and FIG. 11.

At a step 915, the second paver assembly 110 is provided adjacent to the first paver assembly 110, wherein the two straps 114 at the two corners of the second paver assembly 110 are aligned to two of the existing paver spacers 130. This step is shown pictorially in FIG. 12 and FIG. 13.

At a step 920, two additional paver spacers 130 are provided. Then, a paver spacer 130 is aligned to each of the straps 114 at the two remaining corners of the second paver assembly 110. This step is shown pictorially in FIG. 13.

At a step 925, the third paver assembly 110 is provided adjacent to and below the second paver assembly 110, wherein the two straps 114 at the two corners of the third paver assembly 110 are aligned to two of the existing paver spacers 130. This step is shown pictorially in FIG. 14 and FIG. 15.

At a step 930, two additional paver spacers 130 are provided. Then, a paver spacer 130 is aligned to each of the straps 114 at the two remaining corners of the third paver assembly 110. This step is shown pictorially in FIG. 15.

At a step 935, the fourth paver assembly 110 is provided adjacent to the first and third paver assemblies 110. Then, the straps 114 at the three corners of the fourth paver assembly 110 are aligned to the existing paver spacers 130. This step is shown pictorially in FIG. 16, FIG. 17, and FIG. 18.

At a step 940, one additional paver spacer 130 is provided. Then, the paver spacer 130 is aligned to the strap 114 at the remaining corner of the fourth paver assembly 110. This step is shown pictorially in FIG. 1.

At a step 945, washer 140 and the screw 142 are installed at the paver spacer 130 at the intersection of the four paver assemblies 110. For example, FIG. 16 shows that the strap 114 of the fourth paver assembly 110 is pulled back slightly from the centermost paver spacer 130, which is the intersection of the four paver assemblies 110. FIG. 17 shows that this allows enough room to drop the washer 140 into place atop this strap 114. Then, FIG. 18 shows that, with the washer 140 in place, the fourth paver assembly 110 can be slid into place with respect to the centermost paver spacer 130. FIG. 19 shows the four paver assemblies 110 in place with respect to the centermost paver spacer 130 and with the washer 132 in place. Then, FIG. 20 shows the screw 142 being installed through the washer 132 and through the stack of four straps 114 at the centermost paver spacer 130. The screw 142 is tightened into the threaded nut 134 (not visible) in the centermost paver spacer 130. FIG. 21, FIG. 22, FIG. 23, and FIG. 24 show another sequence of the screw 142 being tightened into the threaded nut 134 in the centermost paver spacer 130.

Using the method 900, the complete field of paver assemblies 110 are tied together to form a paver safety net and tie down system, which has the effect of a large safety net under the paver system. The bonding layer 116 along with the embedded 1-inch nylon straps 114 in an X pattern within each paver assembly 110 add strength to the pavers 112 as well as holding any sharp shards and pieces suspended and together should a paver 112 happen to break from heavy weight or shocking impact. Accordingly, the presently disclosed paver lock down system 100 and methods 300, 900 provide a composite, reinforced backing system to any nearly any paver, such as a standard 2-cm thick (or any other thickness) porcelain pavers (any manufacturer).
