DETAILED DESCRIPTION

Overview

Embodiments described herein are directed to a reversible deck system. The reversible deck system may be installed on a deck structure. The deck system is described as reversible because it may be installed onto the deck structure in two different orientations. In a first orientation, a walking surface is facing upward. The walking surface is substantially solid (e.g., without gaps) and forms a final finished surface of a deck. The final finished surface is a surface people walk on and objects (e.g., tables and chairs) rest on. In a second orientation, the walking surface is facing downward. In the downward facing orientation, a joist structure onto which deck boards (e.g., wood or composite) may be installed is facing upward. The deck boards may be installed perpendicular to the joists.

The reversible deck system includes four major structural members, including a wide deck plank, a narrow deck plank, a tongue edge cap, and a groove edge cap. The deck assembly may be formed by joining a plurality of wide deck planks and narrow deck planks to form a deck surface with desired dimensions. A tongue side cap forms one edge of the deck assembly, while a groove edge cap forms the other edge. In an aspect, the major structural members may be formed through an aluminum extrusion process. The major structural members may be attached to a deck structure using screws, adhesive, bolts, and or other suitable connection technologies.

Turning now to FIG. 1, a perspective view of a portion of a wide deck plank 100 is shown, in accordance with various embodiments. The wide deck plank 100 may be rectangular (from a top view) and have a relatively thin cross-section. The wide deck plank 100 may be eight feet in length, or six feet in length, or three feet in length or the like and about 8 inches wide between its corresponding sides. Only a portion of the wide deck plank 100 is shown for the sake of highlighting various features that generally extend the entire length of the wide deck plank 100. The wide deck plank 100 may comprise a generally a planar walking surface 102. The planar walking surface 102 includes a plurality of grooves 104 that run substantially parallel to the length of the planar walking surface 102. The planar walking surface 102 may be described as a rectangular walking surface herein because a top view of the planar walking surface 102 may have a rectangular shape.

The wide deck plank 100 is shown with a walking surface 102 facing upward and a joist connection structure 142 facing downward. The walking surface 102 may serve as a final exposed surface for a deck assembly on which people walk and objects (e.g., tables and chairs) are supported. Alternatively, the wide deck plank 100 may be installed with the joist connection structure 142 facing upward. In this orientation, deck boards may be installed on top of the joist connection structure 142. The deck boards could be installed with an orientation that is substantially perpendicular to the length of the joist connection structure 142.

A first edge of the wide deck plank 100 includes an elongated groove 140, which may extend along the entire end of the wide deck plank 100. The first edge may be described herein as the groove edge. The elongated groove 140 may have a U-shaped cross section. A second edge of the wide deck plank 100, opposite of the grove edge, includes a tongue 110, which may extend along the entire end of the wide deck plank 100. The second edge may be described herein as the tongue edge. The tongue 110 is located approximately a thickness of the walking surface 102 below the walking surface 102. This location of the tongue 110 defines an upper outside surface 106, and a lower outside surface 108 of a tongue-edge flange 112 that extends vertically from the wide deck plank 100 in a direction substantially perpendicular to the walking surface 102. A deck assembly may be formed, in part, by inserting a tongue from an adjacent reversible deck plank (not shown) or other component into the groove 140 of the wide deck plank 100.

A first rib 114 and a second rib 116 descend generally vertically from the planar walking surface 102. These ribs may rest on a flange or other portion of an interlocking member, such as narrow reversible deck plank 200, groove-side end cap 300, and/or tongue-side end cap 400. These ribs may extend across the entire length of the wide deck plank 100 from one of its ends to the other.

The wide deck plank 100 includes a joist section 118, which extends downward from a leg 124 attached to a lower edge of the groove 140.

The joist connection structure 142 is below and substantially parallel to the walking surface 102. The joist connection structure 142 extends the length of the wide deck plank 100. An upper-leg flange 120 extends perpendicularly from the leg 124 toward the tongue edge side of the wide deck plank 100. A lower-leg flange 122 extends perpendicularly from the leg 124 toward the tongue edge side of the wide deck plank 100.

The joist section 118 includes a rib 126 extending in an upward orientation that is substantially parallel to the leg 124 and perpendicular to the joist connection structure 142. An upper-rib flange 130 extends perpendicularly from the rib 126 toward the groove edge side of the wide deck plank 100. A lower-rib flange 132 extends perpendicularly from the rib 126 toward the groove edge side of the wide deck plank 100. When joined with a second plank, the bottom of the rib 114 may rest on the top surface of an upper-rib flange 130 of the second plank (not shown). In an aspect, the top surface 128 of the rib 126 is the approximately the same distance from the top-facing surface 134 of the joist connection structure 142 as the bottom edge of the groove 129. The joist connection structure 142 includes a fastener groove 133 through which screws, or other fasteners, may be driven.

Turning now to FIG. 2, a perspective view of a portion of a narrow deck plank is shown, in accordance with various embodiments. In an aspect, the narrow deck plank is one-third, half, or two-thirds the width of the wide deck plank. The narrow deck plank 200 may be rectangular (from a top view) and have a relatively thin cross-section. The narrow deck plank 200 may be eight feet in length, or six feet in length, or three feet in length or the like and about 8 inches width between its corresponding sides. Only a portion of the narrow deck plank 200 is shown for the sake of highlighting various features that generally extend the entire length of the narrow deck plank 200. The narrow deck plank 200 may comprise a generally a planar walking surface 202.

A lower-leg flange 222 extends perpendicularly from the leg 224 toward the tongue edge side of the narrow deck plank 200.

The joist section 228 includes a rib 226 extending in an upward orientation that is substantially parallel to the leg 224 and perpendicular to the joist connection structure 242. An upper-rib flange 230 extends perpendicularly from the rib 226 toward the groove edge side of the narrow deck plank 200. A lower-rib flange 232 extends perpendicularly from the rib 226 toward the groove edge side of the narrow deck plank 200. When joined with a second plank, the bottom of the rib 214 may rest on the top surface of an upper-flange 230 of the second plank (not shown). In an aspect, the top surface 228 of the rib 226 is the approximately the same distance from the top-facing surface 234 of the joist connection structure 242 as the bottom edge of the groove 229. The joist connection structure 242 includes a fastener groove 233 through which screws, or other fasteners, may be driven.

Turning now to FIG. 3, a perspective view of a portion of a groove-side end cap 300 is shown, in accordance with various embodiments. The groove-side end cap 300 forms one edge of a deck assembly that may include wide deck planks 100, narrow deck plank 200, and tongue-side end cap 400. The groove-side end cap 300 includes a tongue 310 that is sized to fit into the groove 140 of the wide deck plank 100 or the groove 240 of the narrow deck plank. The tongue 310 is located approximately a thickness of the top 304 below the top 304. This location of the tongue 310 defines an upper outside surface 306, and a lower outside surface 308 of a tongue-edge flange 312 that extends vertically from the top 304 in a direction substantially perpendicular to the top 304.

The groove-side end cap 300 includes a top 304, the top surface of which may form part of the walking surface of the deck assembly when installed in the orientation shown in FIG. 3. The sidewall 302 forms a visible edge of the assembled deck. A rib 306 descends generally vertically from the top 304.

Turning now to FIG. 4, a perspective view of a portion of a tongue-side end cap 400 is shown, in accordance with various embodiments. The tongue-side end cap 400 forms one edge of a deck assembly that may include wide deck planks 100, narrow deck planks 200, and a groove-side end cap 300. The tongue-side end cap 400 includes a groove 430 that is sized to fit into the tongue 110 of the wide deck plank 100 or the tongue 210 of the narrow deck plank. The tongue-side end cap 400 includes a top 416, the top surface of which may form part of the walking surface of the deck assembly when installed in the orientation shown in FIG. 4.

An upper-leg flange 422 extends perpendicularly from the leg 420 to form the lower end of the groove 430.

The joist section 418 includes a rib 406 extending in an upward orientation that is substantially perpendicular to the joist connection structure 402. An upper-rib flange 410 extends perpendicularly from the rib 406. A lower-rib flange 412 extends perpendicularly from the rib 406 toward the groove edge side of the tongue-side end cap 400.

Turning now to FIG. 5, an enlarged view in cross-section of deck assembly oriented with a walking surface facing upward is shown, in accordance with various embodiments. The wide deck plank 100, narrow deck plank 200, groove-side end cap 300, and tongue-side end cap 400 have been described previously, along with their various elements. The combination of components allows a deck surface to various sizes and shapes to be formed. The first step in building a deck is planning and design. This involves determining the size, shape, and location of the deck, as well as the materials to be used. The design should also take into account the type of soil (if supported by the ground), the slope of the land, and local building codes. In addition to a deck supported directly by the ground, the reversible decking could be used to form a balcony or walking surface attached to building without direct support from the ground. The deck planks and decking system described herein can be combined to form a deck surface having many different sizes and shapes. While the planks and end caps may have fixed widths. They can be cut to different lengths.

If the deck is supported by the ground, as might be typically found in a backyard deck, then the next step is to dig holes for the footings, which are concrete bases that support the deck's weight. The footings are typically made of concrete and are placed below the frost line to prevent shifting during freeze-thaw cycles. Posts, which are vertical supports, are then attached to the footings using post anchors.

Beams and joists may comprise the main support structure for the deck. The reversible decking described herein may be attached to beams and joists. Beams are horizontal supports that are attached to the posts and/or main structure. In aspects, the beams may be supported by cables (such as in the case of a balcony attached to an apartment building) or other structural members. The beams carry the weight of the deck and transfer it to the footings, posts, and/or other structural members. Joists are attached to the beams and provide a surface to which the decking boards are attached. Joist hangers, which are metal brackets, may be used to secure the joists to the beams. The decking forms the surface of the deck. Decking boards are attached to the joists using deck screws, hidden fasteners, or other methods. The reversible decking may include marks indicating where screws should be used to secure the deck plank to the joists or other structural members.

Turning now to FIG. 6, an enlarged view in cross-section of deck assembly oriented with a walking surface facing downward is shown, in accordance with various embodiments. The wide deck plank 100, narrow deck plank 200, groove-side end cap 300, and tongue-side end cap 400 have been described previously, along with their various elements. A deck board 610 is shown installed on the joist connection structures provided by the deck assembly. The deck board 610 is installed perpendicular to the joist connection structures.

Turning now to FIG. 7, a cross-section 701 of a wide deck plank 100 is shown, in accordance with various embodiments. The wide deck plank 100 has been described previously. The cross-section 701 may be used as a die template in the aluminum extrusion process. Aluminum extrusion is a technique used to transform aluminum alloy into objects with a definitive cross-sectional profile, such as the cross-section 701 of the wide deck plank 100. The extrusion process makes the most of aluminum's unique combination of physical characteristics. Its malleability allows it to be easily machined and cast, and yet aluminum is one third the density and stiffness of steel so the resulting products offer strength and stability, particularly when alloyed with other metals. The process of aluminum extrusion consists of the following steps: After designing and creating the shape of the die (e.g., deck plank cross section), a cylindrical billet of aluminum alloy is heated to 800° F.-925° F. The aluminum billet is then transferred to a loader, where a lubricant is added to prevent it from sticking to the extrusion machine, the ram or the handle. Substantial pressure is applied to a dummy block using a ram, which pushes the aluminum billet into the container, forcing it through the die.

Upon exiting the die, the extruded aluminum is quickly cooled with fans or water. This rapid cooling hardens the aluminum. The speed of the cooling process may be controlled to maintain the desired properties of the aluminum. After cooling, the extruded aluminum is moved to a stretcher, for straightening and work hardening. The hardened extrusions are brought to the saw table and cut according to the required lengths. The final step is aging, during which the aluminum is baked in an aging oven, which speeds up the hardening process. Additional complexities may be created during this process by adding a variety of fabrication techniques and finishes, such as anodizing or painting.

Turning now to FIG. 8, a cross-section 801 of the narrow deck plank 200 is shown, in accordance with various embodiments. The narrow deck plank 200 has been described previously. As described above, the cross-section 801 may be used as a die template in the aluminum extrusion process.

Turning now to FIG. 9, a cross-section 901 a groove-side end cap 300 is shown, in accordance with various embodiments. The groove-side end cap 300 has been described previously. As described above, the cross-section 901 may be used as a die template in the aluminum extrusion process.

Turning now to FIG. 10, a cross-section 1001 a tongue-side end cap 400, in accordance with various embodiments. The tongue-side end cap 400 has been described previously. As described above, the cross-section 1001 may be used as a die template in the aluminum extrusion process.
