DETAILED DESCRIPTION OF EMBODIMENTS

For purposes of description herein the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal” and derivatives thereof shall relate to the invention as oriented in FIG. 1. However, it is to be understood that the invention may assume various alternative orientations and step sequences, except where expressly specified to the contrary. As used herein, “uphill” or the “uphill direction” refers to being located higher in the vertical direction (upon installation, unless described otherwise). Correspondingly, as used herein, “downhill” or the “downhill direction” refers to being located lower in the vertical direction (upon installation, unless described otherwise). It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

The embodiment of an interlocking panel system 10 for installation on an underlying structure 12 shown in FIGS. 1-6A includes a plurality of panels 14. The panels 14 are suitable for installation on a roof, a wall, or other underlying structure 12 in a top-down manner. Once installed, the panels 14 form a watertight barrier over the underlying structure 12, with fasteners hidden from view.

As best shown in the embodiment depicted in FIGS. 1-3, each of the panels 14 includes a generally rectangular panel body 16 with an uphill edge 18 and an opposing downhill edge 20. An interlocking member 22 is disposed along the uphill edge 18 of each panel body 16, and a receiving member 24 is disposed along the downhill edge 20 of each panel body 16. The receiving member 24 of each uphill panel 14A is adapted to receive the interlocking member 22 of an adjacent downhill panel 14B, and the receiving member 24 has a span 26, which permits positional adjustment of the downhill panel 14B within a defined range.

With reference again to FIGS. 1-3, a joining flange 28 is also disposed along a length of the receiving member 24 for affixing the panel 14 to the underlying structure 12. Upon installation of the adjacent downhill panel 14B, the joining flange 28 is disposed between the underlying structure 12 and the adjacent downhill panel 14B. The fasteners 30 are used to attach the joining flange 28 to the underlying structure 12. The fasteners 30 may be used for attachment of a roofing panel or a siding panel to the underlying structure 12, and are appropriate for affixing the joining flange 28 to the underlying structure 12, including, without limitation, nails, screws, adhesives, or other fasteners.

The interlocking member 22, as shown in the embodiment depicted in FIGS. 2 and 3, includes an angled head 32 disposed along the uphill edge 18 of the panel body 16. The angled head 32 includes a flange 34 that extends from the uphill edge 18 of the panel body 16, folding back over the panel body 16 at an angle α of less than 90 degrees from the panel body 16. The flange 34 of the angled head 32 extends a first length L over the panel body 16 and a first height H up from the surface of the panel body 16.

As shown in the embodiment depicted in FIGS. 2 and 3, the receiving member 24 includes a trough 36 disposed along the downhill edge 20 of the panel body 16. The trough 36 defines a receiving slot 37. The trough 36 includes a downwardly depending wall 38, a top wall 40, a back wall 42, and a bottom wall 44. The downwardly depending wall 38 depends from the downhill edge 20 of the panel body 16. The back wall 42 opposes the downwardly depending wall 38, and as shown in FIGS. 2 and 3, is located uphill from the downwardly depending wall 38. The back wall 42 also has a length which is greater than the length of the downwardly depending wall 38. Also, as shown in FIGS. 2 and 3, the bottom wall 44 extends beyond the downhill edge 20 of the panel body 16 to form the joining flange 28.

As shown in the embodiment depicted in FIG. 3, the difference in length between the back wall 42 and the downwardly depending wall 38 results in an opening 46 on a downhill side of the trough 36, allowing insertion of the interlocking member 22 into the receiving member 24. The opening 46 has a height X, which is less than the first height H that the flange 34 of the angled head 32 extends above the panel body 16. The flange 34 is a material which is at least slightly deformable, allowing it to be inserted through the opening 46, and then expand to the first height H, which is greater than the height X of the opening 46.

Additionally, a length Y of the top wall 40 is greater than the first length L that the flange 34 of the angled head 32 extends over the panel body 16. The difference in the length Y between the top wall 40 and the first length L of the flange 34 overlapping the panel body 16 allows positional adjustment of the downhill panel 14B with respect to the uphill panel 14A in an uphill-downhill direction. This room for adjustment (Y-L) allows for the alignment of adjacent courses of panels 14, and allows for coverage of potential inconsistencies in the underlying structure 12. The difference in length between the top wall 40 and the overlapping length of the flange 34 (Y-L) is preferably equal to or greater than about 0.25 inches, to allow for adjustment of the downhill course with respect to the uphill course.

As shown in the embodiment depicted in FIG. 4, each generally rectangular panel body 16 also includes a right edge 48 and a left edge 50, in addition to the uphill and downhill edges 18, 20. A watertight course of panels 14 includes panels 14 affixed to the underlying structure 12 from left to right (or right to left) to form a horizontal line with the left edge 50 of each panel 14 overlapping the right edge 48 of the adjacent panel 14 (or vice versa). As shown in the embodiment of FIGS. 1-6A, interlocking flange features 52 are provided on the right edge 48 and the left edge 50 to permit adjacent (side-by-side) panels 14 to interlock. Adjacent flange features 52 can be interlocked from left to right (or right to left) across the underlying structure 12, thereby allowing the panels 14 to be installed in the watertight horizontal course.

As best shown in the embodiment depicted in FIGS. 5-6A, each panel 14 may include more than one depiction of a “shingle” thereon, to maintain the appearance of traditional shingled roofing or siding materials, but to ease installation. In one embodiment, the panels 14 are formed to look like a multitude of slate/stone roofing tiles. The panels 14 may also include alternate patterns, stampings, or texturing to appear similar to existing materials, or to have a unique appearance not possible with existing roofing or siding materials. The panels 14 may be manufactured from any material (or a combination of materials) suitable for use as a roofing or siding material, which can be formed to have the described interlocking and receiving members, including, without limitation, metal suitable for use as a roofing or siding material.

To install the interlocking panel system 10 on an underlying structure 12, a first panel 14A is placed in position on the underlying structure 12 with the uphill edge 18 higher on the underlying structure 12 than the downhill edge 20, and is affixed thereto via the fasteners 30 through or applied to the joining flange 28. As affixed, the receiving member 24 is disposed along the downhill edge 20 of the first panel 14A. Adjacent panels 14A (to the right or left side of the first panel 14A) can then be optionally affixed to the underlying structure 12, overlapping the right and left edges 48, 50 of the previously installed panel 14A, to form an uphill course of panels 14A extending horizontally.

A second panel 14B is then positioned on the downhill side of the first panel 14A, such that its uphill edge 18 is facing the downhill edge 20 of the first panel 14A. The interlocking member 22 disposed along the uphill edge 18 of the second panel 14B is inserted into the receiving member 24 disposed along the downhill edge 20 of the first panel 14A, such that the interlocking member 22 is received within the receiving member 24. As best shown in FIG. 3, when the interlocking member 22 is received within the receiving member 24, the height H of the flange 34 of the angled head 32 is greater than the height X of the opening 46 to the receiving member 24. Consequently, the second panel 14B is retained in the receiving slot 37 of the first panel 14A.

The flange 34 of the angled head 32 also has a length L overlapping the second panel 14B, which is less than the span 26 of the receiving member 24. Due to this difference in length, once the interlocking member 22 of the second panel 14B is received within the receiving member 24, the second panel 14B is adjustable in the uphill-downhill direction within the span 26 of the receiving member 24, allowing the second panel 14B to be adjusted to take into account anomalies in the underlying structure 12 and to maintain straight lines over a course of panels 14. Once in the desired position, the second panel 14B is affixed to the underlying structure 12 via the fasteners 30 applied to or through the joining flange 28 on the downhill edge 20 of the second panel 14B.

An adjacent panel 14B (to the right or left side of the second panel 14B) is then optionally affixed to the underlying structure 12, overlapping the side edge of the previously installed panel 14B, to form a downhill course of panels 14B. The second panel 14B (or the downhill course of panels 14B) can then function as the first panel 14A (or uphill course of panels 14), allowing the installation of another course of panels 14 on the downhill edge 20 of the second panel 14B (or downhill course of panels 14B). When installing one course of panels 14B on the downhill edge 20 of an uphill course of panels 14A, the panels 14B of the downhill course may be aligned edge-to-edge with the uphill course of panels 14A, or may be offset therefrom to create a staggered arrangement.

With reference again to FIG. 3, the interlocking panel system 10, as described above, is able to be installed on the underlying structure 12 in a top-down manner, with hidden fasteners 30 to improve the appearance and improve the water barrier created by the interlocking panel system 10. The interlocking panel system 10 also incorporate span 26, which permits positional adjustment of the downhill panel 14B with respect to the uphill panel 14A, ensuring that the appearance of the interlocking panel system 10 remains uniform and forms a straight line at the desired bottom end-point, and that variations in the underlying structure 12 and any tolerance stack-ups are accommodated by the interlocking panel system 10.
