DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
~ ~ Referring now to the FIGS., a snow guard in accordance with the present invention is at 10. Snow guard 10 includes a resilient body 12 having a slot 14 for receiving a of a standing seam 16 of a metal roof 18. A pair of apertures 20 is provided in body 12 for manipulating body 12 to selectively widen slot 14 to facilitate the installation of snow 10 upon standing seam 16. A number of teeth 22 project inwardly from body 12 into ~~ slot 14 to firmly grip standing seam 16. A pair of wings 24 extends outwardly from body 12 to impede the downward movement of snow on roof 18.
Body 12 includes a pair of rectangular plates 26 that are positioned side-by-side. Plates 26 have a height that is somewhat greater than that of seam 16. The width of plates 26 is about one and one half times their height. Plates 26 have a thickness of about 1 / 16 inch ( 1. 5 . I I~>
One aperture 20 penetrates the bottom of each plate 26. Each aperture 20 is configured to easily receive one of the jaws 28 of a hand tool 30 that is capable of pulling plates 26 away from one another. Thus, the portion of each plate 26 defining the bottom of each aperture 20 3 ' . ~~
projects outwardly so as to define a. protruding lip 32 that permits the smooth insertion and of one of jaws 28. Further, each aperture 20 is elongated to permit an even distribution of force to be applied to plates 26 by tool 30.
Each plate 26 is provided with a plurality of teeth 22. Teeth 22 are positioned above I laperture 20 to engage seam 16 immediately below its relatively stiff apex.
Teeth 22 extend in a spaced-apart manner from one end of the plate 26 to the other to ensure a strong grip upon seam 16.
Teeth 22 are triangular in outline. Each tooth 22 has a wide base that falls within a I IPI~e that is substantially parallel to wings 24 and that measures about 1/8 inch (3 mm) across.
~ ~ From its base, each tooth 22 tapers in width to a pointed tip that projects away from wings 24 and also about 1/8 inch (3 mm) into slot 14. Due to the relatively great thickness of teeth 22, they are neither easily deformed nor do they give up their grip upon seam 16 without difficulty. Thus, it is very hard to dislodge snow guard 10 from seam 16 without employing tool 30.
~ ~ An opening 34 is positioned adjacent to each tooth 22. Each opening 34 is triangular in outline, being substantially a mirror image of the adjacent tooth 22. Openings 34 enhance the flow of air through slot 14 to aid, albeit in a limited manner, in the cooling roof 18.
Plates 26 are connected together at their tops by a crosspiece 36 so as to provide body 12 with a cross section resembling an inverted "U". Crosspiece 36 is provided with a pair of .'~2 o spaced-apart holes 38 respectively positioned at its opposite ends.
Threaded fasteners (not shown) can be passed through holes 38 for the attachment of a snow-retaining rail 40 to snow guard 10.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
~ ~ Referring now to the FIGS., a snow guard in accordance with the present invention is at 10. Snow guard 10 includes a resilient body 12 having a slot 14 for receiving a of a standing seam 16 of a metal roof 18. A pair of apertures 20 is provided in body 12 for manipulating body 12 to selectively widen slot 14 to facilitate the installation of snow 10 upon standing seam 16. A number of teeth 22 project inwardly from body 12 into ~~ slot 14 to firmly grip standing seam 16. A pair of wings 24 extends outwardly from body 12 to impede the downward movement of snow on roof 18.
Body 12 includes a pair of rectangular plates 26 that are positioned side-by-side. Plates 26 have a height that is somewhat greater than that of seam 16. The width of plates 26 is about one and one half times their height. Plates 26 have a thickness of about 1 / 16 inch ( 1. 5 . I I~>
One aperture 20 penetrates the bottom of each plate 26. Each aperture 20 is configured to easily receive one of the jaws 28 of a hand tool 30 that is capable of pulling plates 26 away from one another. Thus, the portion of each plate 26 defining the bottom of each aperture 20 3 ' . ~~
projects outwardly so as to define a. protruding lip 32 that permits the smooth insertion and of one of jaws 28. Further, each aperture 20 is elongated to permit an even distribution of force to be applied to plates 26 by tool 30.
Each plate 26 is provided with a plurality of teeth 22. Teeth 22 are positioned above I laperture 20 to engage seam 16 immediately below its relatively stiff apex.
Teeth 22 extend in a spaced-apart manner from one end of the plate 26 to the other to ensure a strong grip upon seam 16.
Teeth 22 are triangular in outline. Each tooth 22 has a wide base that falls within a I IPI~e that is substantially parallel to wings 24 and that measures about 1/8 inch (3 mm) across.
~ ~ From its base, each tooth 22 tapers in width to a pointed tip that projects away from wings 24 and also about 1/8 inch (3 mm) into slot 14. Due to the relatively great thickness of teeth 22, they are neither easily deformed nor do they give up their grip upon seam 16 without difficulty. Thus, it is very hard to dislodge snow guard 10 from seam 16 without employing tool 30.
~ ~ An opening 34 is positioned adjacent to each tooth 22. Each opening 34 is triangular in outline, being substantially a mirror image of the adjacent tooth 22. Openings 34 enhance the flow of air through slot 14 to aid, albeit in a limited manner, in the cooling roof 18.
Plates 26 are connected together at their tops by a crosspiece 36 so as to provide body 12 with a cross section resembling an inverted "U". Crosspiece 36 is provided with a pair of .'~2 o spaced-apart holes 38 respectively positioned at its opposite ends.
Threaded fasteners (not shown) can be passed through holes 38 for the attachment of a snow-retaining rail 40 to snow guard 10.
4 ' .. II CA 02490471 2004-12-17 An alternative arrangement for securing rail 40 to snow guard 10 is shown in FIG. 5.
a clip 42 is employed rather than threaded fasteners. Clip 42 includes a pair of arms 44 at their tops by a crosspiece 46 in the manner of an inverted "U" . A finger jects inwardly from the bottom of each arm 44 and is adapted for snug insertion into an I aperture 20. When fingers 48 are positioned within apertures 20, the tops of arms 44 extend crosspiece 36 of snow guard 10. Transverse bores 50 in the tops of arms 44 snugly ve rail 40 so that rail 40 is rigidly secured to snow guard 10.
One wing 24 extends outwardly at right angles from the front end of each of plates 26.
ings 24 are substantially square in outline, having the same height as that of plates 26 and I (having about the same width as their height. The surface area provided to wings 24 is believed be adequate to prevent large masses of snow and ice, capable of causing great bodily injury, from sliding off roof 18.
The outer end of each wing 24 has a pair of bores 52. As shown, bores 52 and are itioned one above the other and have approximately the same diameter as that of holes 38.
I Bores 52 are provided for the attachment of signs, antennas and lightening rods (none, shown) to roof 18.
Snow guard 10 is formed by cutting and folding portions of a planar blank 54 that is a single piece of heavy gauge spring steel: First, apertures 20, holes 38 and bores 52 are made by cutting such at suitable locations in blank 54. Next, teeth 22 are made by cutting a plurality of 2 o I I V-shaped notches 56 in blank 54 and, then, folding the material within notches 56 downwardly along the fold lines 58 positioned across the front ends of notches 56. (It is the voids left within notches 56 by the production of teeth 22 that form openings 34.) Later, lips and 32 are made by a the portions of blank 54 bounded by apertures 20 and fold lines 60 slightly upward.
ow, body 12 is given its inverted U-shape by making a right angle bends along fold lines 62 on sides of holes 38. Finally, outstretched wings 24 are provided to snow guard 10 by the material separated from plates 26 by fold lines 64 outwardly. The resulting snow ~ guard 10 is ready to use although powder coating is recommended to prolong its useful life.
The use of snow guard 10 is straightforward. First, the jaws 28 of tool 30 are inserted into apertures 20 on opposite sides of body 12. Next, the handles 66 of tool 30 are squeezed spreading jaws 28 and temporarily spreading plates 26 from one another. This action takes slot 14 from its normal, narrow, seam-clamping width illustrated by the solid line 1 o position shown most clearly in FIG. 4 to a wide, seam-releasing width shown in FIG. 6.
Snow guard 10 can now be easily positioned upon standing seam 16 with wings 24 on the side. When the pressure on the handles 66 is released, body 12 springs back to its configuration. By withdrawing jaws 28 from apertures 20, installation of snow upon standing seam 16 is completed.
~ ~ Snow guard 10 can be enhanced with the addition of snow-retaining rail 40 and attachment clip 42. To do this, arms 44 are first spread away from one by the application of a prying force from jaws 28 of tool 30. Next, forgers 48 are positioned within apertures 20 of the seam-mounted snow guard 10 and tool 30 is disengaged from clip 42. Finally, rail 40 is extended through transverse bores 50 in the top of clip 42 and through the clips 42 secured to 2 0 ~ ~ adjacent snow guards 10 on roof 18. The resulting snow guard assembly is capable of supporting very heavy loads of snow and ice without damage to roof 18.
a clip 42 is employed rather than threaded fasteners. Clip 42 includes a pair of arms 44 at their tops by a crosspiece 46 in the manner of an inverted "U" . A finger jects inwardly from the bottom of each arm 44 and is adapted for snug insertion into an I aperture 20. When fingers 48 are positioned within apertures 20, the tops of arms 44 extend crosspiece 36 of snow guard 10. Transverse bores 50 in the tops of arms 44 snugly ve rail 40 so that rail 40 is rigidly secured to snow guard 10.
One wing 24 extends outwardly at right angles from the front end of each of plates 26.

Finally, outstretched wings 24 are provided to snow guard 10 by the material separated from plates 26 by fold lines 64 outwardly. The resulting snow ~ guard 10 is ready to use although powder coating is recommended to prolong its useful life.

Snow guard 10 can now be easily positioned upon standing seam 16 with wings 24 on the side. When the pressure on the handles 66 is released, body 12 springs back to its configuration. By withdrawing jaws 28 from apertures 20, installation of snow upon standing seam 16 is completed.
~ ~ Snow guard 10 can be enhanced with the addition of snow-retaining rail 40 and attachment clip 42. To do this, arms 44 are first spread away from one by the application of a prying force from jaws 28 of tool 30. Next, forgers 48 are positioned within apertures 20 of the seam-mounted snow guard 10 and tool 30 is disengaged from clip 42. Finally, rail 40 is extended through transverse bores 50 in the top of clip 42 and through the clips 42 secured to 2 0 ~ ~ adjacent snow guards 10 on roof 18. The resulting snow guard assembly is capable of supporting very heavy loads of snow and ice without damage to roof 18.
While snow guard 10 has been described with a high degree of particularity, it will be by those skilled in the art that modifications can be made to it. Therefore, it is to be that the present invention is not limited strictly to snow guard 10 described above, encompasses any and all embodiments of a snow guard within the scope of the following S
