Snow guard

DETAILED DESCRIPTION The embodiments of the invention in which an exclusive property or privilege is claimed are as follows: 1.
A snow guard having a width and a depth, a base means for securing the snow guard to a roof, and wing means extending upwardly from the base means generally along the width of the snow guard for impeding the passage of snow, the improvement wherein the undersurface of the base means has a corrugate profile including an arched portion having an axis generally extending along the depth of the base member and pair of synclines parallel thereto on transversely opposed sides thereof.
2.
A snow guard as defined in claim 1 wherein said base means has a substantially uniform thickness.
3.
A snow guard as defined in claim 2 wherein said base means is substantially continuous across the depth and width thereof.
4.
A snow guard as defined in claim 1 wherein said arched portion is defined in part by an apex and each said syncline is defined in part by a trough and wherein said base means is provided with a plurality of openings therethrough for securing said snow guard to an underlying roof, ones of said openings being disposed along the troughs of said synclines, others of said openings being disposed along the apex of said arched portion.
5.
A snow guard as defined in claim 4 wherein each said opening is surrounded on the upper surface of said base means by a flat to provide a sealing surface.
6.
A snow guard as defined in claim 1 wherein the depth of said base means increases on approach to said apex.
7.
A snow guard as defined in claim 1 wherein each said syncline is defined in part by a trough and wherein said synclines are asymmetric, with the slope of said base means forming said synclines being greater in portions thereof residing laterally outwardly of said troughs than in portions residing laterally inwardly thereof.
8.
A snow guard as defined in claim 1 wherein said wing means is continuously connected to said base means along substantially the whole of the length of the wing means
