BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to panel systems, such as generally flat sections used in building, construction and other applications, including in walls, siding, flooring, tiling, shelving, furniture and like. In non-limiting embodiments the present invention provides a system of interlocking siding panels and a method of making interlocking siding panels.
2. Description of Related Art
Vinyl and metal siding panels, such as those used to cover the exterior of a building, generally are formed as single lap panels that extend horizontally across the building. In cases where a single panel is not long enough to extend across an entire surface of a building, multiple panels may be positioned horizontally adjacent to one another. Horizontally adjacent siding panels may overlap one another, such as when the siding panels are thin or hollow, or may be fastened with their ends in an abutting arrangement such as with a bracket or shim.
Once installed, the siding panels may tend to expand or contract horizontally as the ambient temperature changes. This expansion and contraction may cause irregularities in the seam section between two adjacent panels. For example, if adjacent abutting panels expand, the ends of the adjacent panels may expand toward each other, causing them to deflect away from the building at the seam section. If adjacent abutting panels contract, the ends of the panels may draw away from each other, resulting in a gap at the seam section. The gapping created by expansion or contraction of the siding panels may leave openings that can be unsightly, and leave the siding and building surface susceptible to damage from the elements.
In siding panel assemblies having overlapping end portions, the overlapping portion typically is left unfastened, so that the individual panels may expand and contract without causing bulging or gapping. However, the overlapping region leaves an undesirable visible seam. In addition, the gap between the two overlapping sections allows water, air, and insects to pass which may cause damage to the siding panels or the underlying building surface. Furthermore, where the overlapping region is unfastened, the ends of the siding panels can separate, further exacerbating these issues.
In siding panel assemblies having abutting siding panels, additional connectors and similar devices have been used to prevent movement and separation of the ends of the siding panels. However, the use of separate connector pieces complicates the installation and assembly of the siding panels.
The description herein of certain advantages and disadvantages of known methods and devices is not intended to limit the scope of the present invention. Indeed, the present embodiments may include some or all of the features described above without suffering from the same disadvantages.

SUMMARY OF THE INVENTION

In view of the foregoing, it is a feature of the embodiments described herein to provide a system of panels that provides an improved end-to-end seam section with the outer surfaces of the joined panels providing a generally planar surface. In various embodiments, adjacent panels in a siding system may overlap and interlock at a seam section in a secure fashion. Once interlocked, the siding panels may expand and contract without causing a bulge or gap at the seam section. One benefit of siding panel assembly may be that the expansion and contraction associated with the individual siding panels is transferred to the ends of the assembly, rather than the end of each individual siding panel. Another benefit of the siding panel assembly of the embodiments is that it allows for a smoother seam between individual panels, so that it is less apparent from all viewing angles, unlike vinyl siding where the pieces are overlapped, to allow for expansion and contraction.
In embodiments of the invention, a variety of geometries may be provided at the respective ends of adjacent panels (i.e. joints), including without limitation interlocking laps or overlapped ends, tongue and groove ends and butt joints.
In some embodiments adjacent siding ends may by locked by friction fit and/or shape-driven mechanical fit. In various other embodiments the joints may include, without limitation, one or more of frictional fits, shaped mechanical fits, adhesives, mechanical fasteners, welds, melt-bonds and magnets.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The following description is intended to convey a thorough understanding of the embodiments by providing a number of specific embodiments and details involving a siding panel assembly. It is understood, however, that the invention is not limited to these specific embodiments and details, which are exemplary only. It is further understood that one possessing ordinary skill in the art, in light of known devices, systems and methods, would appreciate the use of the invention for its intended purposes and benefits in any number of alternative embodiments.
Generally speaking, as shown in FIG. 1, panel systems 100 of the present invention are generally flat sections used in building, construction and other applications, including in walls, siding, flooring, tiling, shelving, furniture and like. In one described but non-limiting embodiment, a panel system 100 of the invention includes siding panels 110 that have a plurality of horizontally adjacent siding panels 120 that are interlocked on their vertical ends 115 and 125 to provide a composite siding panel 200. The siding panels 110 and 120 are joined together so that the composite siding panel 200 forms a single unit, such as in a row with outer-facing surfaces 117 and 127 of the siding panels providing an exterior siding surface of building in which a row of siding panels forms a substantially planar surface. Any horizontal expansion or contraction of the individual siding panels 110 or 120 is transferred to the end of the composite panel 200, rather than causing gapping or buckling at the junction between two adjacent panels 110 and 120. In some embodiments several composite siding panels 200 may be assembled in horizontal rows, adjacent other composite siding panels 200 along respective horizontal edges of the adjacent rows, to form a siding panel assembly (not shown) that covers a surface, such as the wall of a building.
As used herein, the terms “horizontal” and “vertical” are not intended to be limited to a specific orientation and reflect generally perpendicular sides, edges or ends with respect to one another. The references of “horizontal” and “vertical” as describing one embodiment of the invention are intended to continue to reference the respective edge, side or end in other embodiments where a panel 110 or panel system 100 is provided in another orientation relative to the ground or horizon.
In the various exemplary embodiments, the siding panel systems 100 and their components may be made from solid or foamed polymers, such as vinyl or cellular PVC.
