DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the attached figures, a shingle (generally at 20) is depicted according to one embodiment of the invention and is shown in FIGS. 1-6. The shingle includes a body 22 having each of a left part 24, a right part 26, a top part 28 and a bottom part 30.

The body 22 is rectangular in shape and has a front 32, a rear 34, a left side 36, a right side 38, a top 40 and a bottom 42. As shown, the left part 24 extends from the left side 36 and the right part 26 extends from the right side 38 (see also interconnected side-to-side abutting relationship of FIG. 13). As further shown, the top part 28 extends from the top 40 and the bottom part 30 extends from the bottom 42.

As further shown, one of the left part 24 and right part 26 of the shingle body is folded over the front 32 and the other of the left part and right part is folded over the rear 34. More particularly, in this embodiment, the right part 26 is folded over the front 32 and the left part 24 is folded over the rear 34 (see again FIG. 13).

Similarly, one of the top part 28 and bottom part 30 is folded over the front 32 and the other of the top part and bottom part is folded over the rear 34. More particularly, in this embodiment, the top part 28 is folded over the front 32 and the bottom part 30 is folded over the rear 34.

As further best shown, the shingle body 22 is seen to be substantially planar and solid, except for hollow locations 44 defined adjacent to and extending beneath the top part 28 and can be folded over the front 32 of the shingle body 22. Alternatively, and although not shown, the hollow locations 44 can be redesigned so that they are defined adjacent to and extending behind the bottom part 30 so that they are folded over the rear 34.

Also shown are nailing apertures 46 (shown formed at spaced intervals along the top part 28 folded over the front 32) for receiving roofing nails. Although not shown, the apertures can be relocated along the bottom part 30 within the scope of the invention.

In use, the shingle 20 can be disposed in a generally conventional manner, namely, in an array wherein, in respect of any pair of shingles being arrayed in a side-to-side abutting relationship as shown in FIG. 11, and in which the adjacent sides are interlocked. Additionally, and in respect to any pair of shingles arranged in a top-to-bottom abutting relation, the abutting top part 28 and bottom part 30 are interlocked. This type of interlocking relationship is well-known and as such, neither illustrated nor described in detail.

With reference to FIGS. 7-9, a further embodiment of the invention provides an apparatus (generally at 120) in the form of a clip having a body 122 incorporating a protuberant portion 124. The clip body 122 includes a seat portion 126, a cover portion 128 and a tab portion 130. The seat portion 126 is generally planar as shown. The cover portion 128 is an extension of the seat portion 126 that is folded-over the seat portion, which is further folded to protect outwardly therefrom and then to project over and beyond the seat portion. The cover portion has apertures 132 formed therein. The tab portion 130 has apertures 133 and extends from the cover portion 128.

The protuberant portion 124 extends from the clip body 122 and includes a portion 134 that extends from the seat portion 126 to a stepped portion 136, and a portion 138 is shown that is secured upon itself to define a triangular wedge.

The clip can be positioned as shown in FIG. 10, wherein the seat portion 126 occupies that portion of the hollow 44 that extends beneath the one of the top 28 (as shown) or bottom 30 parts that is folded over the front, with the cover portion 128 disposed in overlapping, close-fitting relation to the top part 28 (or in a non-illustrated embodiment arranged in a similar arrangement with the bottom part 30) and that is folded over the front so that the tab portion 130 extends in substantially planar relation.

Proceeding to FIG. 11, an environmental view is an environmental view showing a roof construction using a plurality of shingles 20 and snow guards arranged in each of side-to-side and top-to-bottom abutting relation so that adjacent sides are interlocked. As illustrated, the lines of the shingles are straight and don't deform to any significant degree by the interposition of the snow guards, this in contrast to the prior art.

FIG. 12 is a side cutaway view the clip taken along cutaway line 12-12 in FIG. 11, secured to a redesigned top part of a shingle body. The clip is similar in overall construction with a similarly configured seating portion, cover portion and tab portion.

FIG. 13 is a cutaway view taken along line 13-13 of FIG. 11 of a side-to-side abutting relationship established between respective left and right parts of adjoining shingle bodies also shown in FIG. 11.

FIG. 14 illustrates an enlarged area 14 in FIG. 12 depicting a bottom portion of a redesigned upper adjoining shingle engaging the seat portion of the clip attached to a lower adjoining shingle (see again FIG. 11).

FIG. 15 illustrates an enlarged area 15 in FIG. 12 and depicting interconnecting portions (see first clip portion secured to the front of the shingle body and inter-engaging second clip portion defining a bottom portion of the clip).

The present invention also discloses a method for use with the shingle and the attachment clip apparatus forming yet another embodiment of the invention. The method includes the steps of the shingle secured to a roof and positioning the clip apparatus such that the seat portion occupies that portion of the hollow location that extends beneath the one of the top and bottom parts that is folded over the front, with the cover portion of the clip disposed in an overlapping, close-fitting relation to the one of the top and bottom parts that is folded over the front.

Other steps include nailing the apparatus to the roof and interlocking the bottom part of a further shingle with the upper part of the shingle and the clip. The apertures in the cover are aligned with the apertures in the shingle and, in this fashion, the bottom part of a further shingle is interlocked with the upper part of the shingle and the clip.

The method results in a shingled roof with snow guards wherein the alignment of the shingles is not materially prejudiced by the interposition of the snow guards, all as shown again in FIGS. 11-15.

It will be appreciated that, in this embodiment, the tab can be nailed to the roof, with the body tightly sandwiched between the seat and the roof and the cover defines a substantially smooth extension of the top part of the shingle (but for the deformed portion). Thus, the mechanical connection between the snow guard and the roof is relatively solid, there is relatively little or no buckling of the shingles associated with the snow guards and the alignment of the shingles in the array is not materially prejudiced.

Having described my invention, other and additional preferred embodiments will become apparent to those skilled in the art to which it pertains, and without deviating from the scope of the appended claims.

The detailed description and drawings are further understood to be supportive of the disclosure, the scope of which being defined by the claims. While some of the best modes and other embodiments for carrying out the claimed teachings have been described in detail, various alternative designs and embodiments exist for practicing the disclosure defined in the appended claims.
