## Abstract

A snow guard that may be secured to both flat tiled roofs and undulating tiled roofs comprises a corrugated base including a central arched portion flanked by a pair of synclines, with a wing member upstanding from the base. The arrangement is inherently stiff and may be secured to the roof by screws or the like passing through the arched portion or through the synclines.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

A snow guard as defined in claim 1 wherein said base means has a substantially uniform thickness.

### Claim 3 (depends on 2)

A snow guard as defined in claim 2 wherein said base means is substantially continuous across the depth and width thereof.

### Claim 4 (depends on 1)

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.

### Claim 5 (depends on 4)

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.

### Claim 6 (depends on 1)

A snow guard as defined in claim 1 wherein the depth of said base means increases on approach to said apex.

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 1)

A snow guard as defined in claim 1 wherein each of said arched portion and said synclines, are defined by an included angle, the included angle of said arched portion being substantially greater than the included angle of said synclines.

### Claim 10 (depends on 1)

A snow guard as defined in claim 1 wherein said arched portion, in the vicinity of the apex thereof is formed with a first radius and said synclines in the vicinity of the trough thereof are formed with a second radius, said first radius being substantially greater than said second radius.

### Claim 11 (depends on 1)

A snow guard as defined in claim 1 wherein a drainage opening is formed through said base means adjacent the juncture of each said syncline and said wing means.

### Claim 12 (depends on 1)

A snow guard as defined in claim 1 wherein said snow guard is unitarily molded from a translucent plastic material.

### Claim 13

A snow guard comprising a base and a wing means upstanding from said base for impeding the passage of snow; said base being substantially continuously formed with a sinuous profile defined by a pair of synclines and an arched portion therebetween, and said wing means being substantially continuously secured to said base along the length of said wing means.

### Claim 14 (depends on 13)

A snow guard as defined in claim 13 wherein said arched portion has an apex formed with a first radius and said synclines at the lower portions thereof are formed with a second radius, said first radius being substantially greater than said second radius.

### Claim 15 (depends on 14)

A snow guard as defined in claim 14 wherein said first radius and said second radius are in the ratio of about 2:1.
