This application claims priority to and the benefit of U.S. Prov. App. No. 61/917,553, filed Dec. 18, 2013, and is incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Disclosure
The present invention relates in general to building products and, in particular, to a single panel siding product.
2. Description of the Related Art
Natural material such as wood shake is used as a building product to cover a substrate of a building, such as a wall. The wood shake provides the function of covering and protecting the wall of the building. In addition, the wood shake has an aesthetically appealing appearance.
Wood shake is traditionally formed from wood such as cedar. Wood shake is relatively expensive to produce because it requires harvesting and splitting of wood, which is time consuming, labor intensive, and results in excess unused wood that is not suitable for shake.
In addition, wood shake is relatively expensive and labor intensive to install. Several individual pieces of wood shake are first mounted to the substrate in a row. Care is taken to space each of the wood shake from each to accommodate for expansion and retraction of the wood shake due to atmospheric changes. A layer of felt is then mounted to the substrate overlapping a portion of the row of wood shake. Then a second row of wood shake is mounted to the substrate overlapping the felt such that the felt interleaves the two rows of shake. This configuration is repeated such that several rows of wood shake interleaved with felt cover the substrate.
With wood shake, the interleaved felt is intended to prevent wind and blowing precipitation from blowing between adjacent pieces of wood shake and below overlapping pieces of wood shake. As such, the felt reduces water logging of the wood shake and water intrusion to the substrate and acts as an insulator. However, as stated above, the material and installation associated with the interleaved felt is relatively expensive and labor intensive.
In addition, attempts to produce polymeric building products to have an appearance that simulates the look of natural material have had limited success. In particular, improvements in the texture and color of the polymeric building product continue to be of interest. Accordingly, there remains an opportunity to develop a building product that has a color variation that simulates natural material and a method of making the same while eliminating the disadvantages highlighted above.
SUMMARY
Embodiments of a siding product are disclosed. The siding product may include a panel having a substantially rectangular structure with a simulated pattern on a front face thereof. The panel may be formed from a polymer. The panel may have a hollow back and be a single shake configuration that does not simulate more than one shake or more than one course of siding.
In other embodiments, the siding product may include a panel having a front face with a simulated pattern. The panel can include a hollow back, a longitudinal length extending in an x-direction, a lateral width extending in a y-direction, and a transverse depth extending in a z-direction. The panel can have a plurality of reinforcement ribs on the hollow back that extend longitudinally in the x-direction and transversely in the z-direction. In a version, none of the reinforcement ribs extend laterally in the y-direction.

DETAILED DESCRIPTION
Embodiments of a system, method and apparatus for a single panel siding product are disclosed. For example, as shown in FIG. 1, the siding product may include a panel 11 having a substantially rectangular structure with a simulated pattern on a front face 13 thereof. In a version, the simulated pattern on the front face 13 may comprise a simulated wood grain or simulated slate look. In some embodiments, a same design, pattern or texture can cover the front face 13 including headlap HL and butt portions BP of the front face 13.
The panel 11 may be formed from a variety of materials, such as polymers. The polymers may be molded and rigid. The panel 11 may include color variegation, as well as two-dimensional or three-dimensional patterns. In a particular embodiment, the panel may comprise polypropylene. In an embodiment, the siding product may include, comprise or consist of a single shake configuration that does not simulate more than one shake or more than one course of siding.
For ease of reference, a Cartesian coordinate system is provided the drawings. The panel 11 has a longitudinal length L extending in an x-direction, a lateral width W extending in a y-direction, a transverse depth D extending in a z-direction. The panel 11 can have an aspect ratio defined as (panel length L):(panel width W). The aspect ratio of the panel 11 can be at least about 1.5:1, such as at least about 1.75:1, or even at least about 2:1. In other versions, the aspect ratio can be not greater than about 3:1, such as not greater than about 2.75:1, or even not greater than about 2.5:1. The aspect ratio can be in a range between any of these values.
As shown in FIG. 2, embodiments of the panel 11 may include a hollow back 15 that is opposite the front face 13. The panel 11 can have a plurality of reinforcement ribs 21, 23 on the hollow back 15. The ribs 21, 23 can extend longitudinally in the x-direction and transversely in the z-direction. In some embodiments, none of the reinforcement ribs 21, 23 extend laterally in the y-direction.
In some versions, the panel 11 may include a side wall 25 extending continuously around a perimeter thereof. The side wall 25 around the panel 11 can define a hollow back depth HBD. See FIGS. 2 and 3. In some versions, the panel 11 can have a hollow back depth HBD of at least about 0.25 inches, such as at least about 0.375 inches, or even at least about 0.50 inches. In other versions, the HBD can be not greater than about 1 inch, such as not greater than about 0.75 inches. The HBD can be in a range between any of these values.
In one embodiment, the transverse depth D and hollow back depth HBD of the panel 11 can be tapered. For example, the D and HBD can decrease from a lower longitudinal end 27 (FIG. 1) to an upper longitudinal end 29. Thus, the dimension of the depth D and hollow back depth HBD can vary in one or more dimensions, such as along the x-axis.
Embodiments of the side wall 25 can have a nominal side wall thickness TSW that is substantially similar to a nominal front wall thickness TFW of the panel 11. Versions of the panel 11 may include a nominal front wall thickness TFW of not greater than about 0.110 inches, such as not greater than about 0.100 inches, or even not greater than about 0.090 inches. In other versions, the TFW can be at least about 0.070 inches, such as at least about 0.080 inches. The TFW can be in a range between any of these values.
Some embodiments of the panel 11 may include features that extend beyond the side wall 25. Such features may comprise at least one interlocking tab, alignment feature, extension, etc. In other embodiments, the panel 11 has no extremities extending beyond the perimeter or side wall 25.
Embodiments of the siding product may include the hollow back 15 having a plurality of long ribs 21. The long ribs 21 can extend in the longitudinal direction. In one version, each long rib 21 can have a lateral or long rib thickness TLR (FIG. 3). The long rib thickness TLR can be substantially similar to a nominal front wall thickness of the panel 11. In other version, the long rib thickness TLR can be less than the nominal front wall thickness TFW. In another example, the long rib thickness TLR can be at least about 33% less than the nominal front wall thickness TFW.
In other embodiments, each long rib 21 can have has a depth DLR (FIG. 4). The long rib depth DLR can be the same or less than the hollow back depth HBD. In a version, each long rib 21 can be tapered in at least one direction, such as the longitudinal direction. The long ribs 21 can be substantially parallel to each other. Lengths of the long ribs can extend only in a longitudinal direction. Each of the long ribs 21 can be located in the hollow back 15. Versions of the long ribs 21 can extend from a top perimeter or side wall 25 of panel 11 (e.g., upper longitudinal end 29) to a bottom perimeter thereof (e.g., lower longitudinal end 27). In a particular embodiment, the panel 11 can comprise only 2 long ribs, such as only 3 long ribs, or even only 4 long ribs.
Embodiments of the siding product can include a hollow back 15 that comprises a plurality of short ribs 23. The short ribs 23 can extend in the longitudinal direction. Each short rib 23 can have a longitudinal length LSR (FIG. 1) that is less than a longitudinal length of the hollow back 15. For example, the short rib longitudinal length LSR can be not greater than about 6 inches, such as not greater than about 5 inches, not greater than about 4 inches, or even not greater than about 3 inches. In other versions, the LSR can be at least about 1 inch, such as at least about 2 inches, or even at least about 3 inches. The LSR can be in a range between any of these values.
The siding product also may include embodiments where each short rib 23 has a lateral thickness TSR (FIG. 4). The TSR can be substantially similar to the nominal front wall thickness TFW of the panel 11. The short rib lateral thickness TSR can be less than the nominal front wall thickness TFW. The TSR can be at least about 33% less than the TFW. Embodiments of the short ribs 23 can be substantially parallel to each other. Other embodiments of the short ribs 23 can extend only in a longitudinal direction.
In another example, at least some of the short ribs 23 do not extend directly from the hollow back 15 and are located on pads 22 (FIGS. 2 and 4) on the hollow back 15. Note that pads 22 appear as protruding pads on the back side of the panel, but appear as recesses on the front side of the panel. As shown in FIG. 2, at least some of the short ribs 23 can extend directly from the hollow back 15 and are not located on pads 22. Embodiments of the short ribs 23 can be tapered in at least one direction, such as the longitudinal direction.
Embodiments of the panel 11 may include a plurality of fastener locations 31 (FIG. 1) in the recesses 22 on the front face 13 thereof. In some examples, the hollow back 15 may include a pad 22 opposite each fastener location 31. See, e.g., FIG. 1B. In one version, each pad 22 can be located adjacent a lateral side edge 25 of the panel 11. Each pad 22 can have a recess depth or pad thickness TP (FIG. 4) in a transverse or depth direction. For example, the pad thickness TP can be the same or less than the hollow back depth HBD.
In some versions, each pad 22 may include a plurality of short ribs 23. Each short rib 23 can have a depth DSR (FIG. 4) that extends in a same direction as the pad thickness TP. A combination of the short rib depth DSR and the pad thickness TP can be equal to or not greater than the hollow back depth HBD.
As shown in FIG. 2, the hollow back 15 can include both long ribs 21 and a set of short ribs 23 between adjacent ones of the long ribs 21. The long ribs 21 can be spaced apart from each other by a long rib spacing SLR. For example, the SLR can be at least about 2 inches. Embodiments of the short ribs 23 can be spaced apart from each by a short rib spacing SSR. For example, the SSR can be not greater than about 0.25 inches.
As shown in the translucent view of FIG. 1B, the panel 11 can have a set of short ribs 23 that are located at a midsection of the long ribs 21 and of the panel 11. As shown in that drawing, the set of short ribs 23 can be located laterally between two adjacent pads 22, substantially in a longitudinal and lateral center of the hollow back 15 and panel 11.
Referring now to FIGS. 5 and 6, an embodiment of the siding product can include a corner panel 51. The corner panel 51 can be essentially formed from two of the panels 11a and 11b, as described herein. The corner panel 51 can have substantially perpendicular panels 11a and 11b configured to be complementary in shape to a corner of a building. Embodiments of the corner panel 51 may comprise a compound mitre, such that each panel 11a, 11b is tapered in at least two directions, as shown. Although the corner panel 51 has two panels 11a, 11b, it has only one panel (i.e., a single panel) on each side of the building (e.g., the two building sides that intersect at a corner) on which it is mounted.
In some versions, each panel 11a, 11b of the corner panel 51 can be cut or trimmed in segments 53, 55. For example, each segment 53, 55 can include a notch 57 (FIG. 7). The notches 57 extend along the longitudinal length of each segment 53, 55 at an outboard intersection of long ribs 21 when facing a rear (i.e., the hollow back 15) of the segment 53, 55. Each segment 53, 55 may include a long rib 21 that extends longitudinally in the hollow back 15. For example, after trimming segment 53 (e.g., along the vertical dashed line in FIG. 7), the long rib 21a becomes the outer perimeter side wall (FIG. 8) of the panel 11. The same procedure may be performed for segment 55, such that long rib 21b would become the outer perimeter side wall.
