Snow guard with snow restraining barrier

Abstract

A snow guard for preventing snow from sliding off a roof top having a longitudinal strap with an up-roof end and a down-roof end, a snow restraining barrier with a generally arcuate shape and supported by a brace, the snow restraining barrier and the brace are both coupled to the down-roof end of the strap, and a rim extending up-roof along the periphery of the snow restraining barrier to grip snow accumulating on the roof top.

1 . A snow guard for preventing snow from sliding off a roof, the snow guard comprising:
 a strap having an up-roof end and a down-roof end;   a snow restraining barrier having a rim extending up-roof along the periphery of the snow restraining barrier, coupled to the down-roof end of the strap; and   a brace supporting the snow restraining barrier coupled to the down-roof end of the strap;   whereby the rim on the snow restraining barrier grips the snow accumulated on the roof.   
   
   
       2 . The snow guard of  claim 1  wherein the rim extends orthogonally up-roof along the periphery of the snow restraining barrier. 
   
   
       3 . The snow guard of  claim 1  wherein the rim is oriented at an angle less than 180° from the up-roof surface of the snow restraining barrier. 
   
   
       4 . The snow guard of  claim 1  wherein the snow restraining barrier has a generally arcuate shape. 
   
   
       5 . The snow guard of  claim 1  wherein the snow restraining barrier is a semi-circular disc. 
   
   
       6 . The snow guard of  claim 1  further comprising a plurality of apertures at the up-roof end of the strap to allow the nailing of the snow guard to the roof. 
   
   
       7 . The snow guard of  claim 1  wherein the brace is pyramidal in shape with arcuate flanges and lateral flanges projecting in opposite directions. 
   
   
       8 . A snow guard having a strap with an up-roof end and a down-roof end, a snow restraining barrier supported by a brace, the snow restraining barrier and brace both coupled to the down-roof end of the strap, the improvement comprising: a rim along the periphery of the snow restraining barrier extending up-roof to grip snow accumulated on a roof. 
   
   
       9 . The snow guard of  claim 8  wherein the rim extends orthogonally up-roof along the periphery of the snow restraining barrier. 
   
   
       10 . The snow guard of  claim 8  wherein the snow restraining barrier has a generally arcuate shape. 
   
   
       11 . The snow guard of  claim 8  wherein the snow restraining barrier is a semi-circular disc. 
   
   
       12 . The snow guard of  claim 8  further comprising a plurality of apertures at the up-roof end of the strap to allow the nailing of the snow guard to the roof. 
   
   
       13 . The snow guard of  claim 8  wherein the snow restraining barrier is integral with, and arises vertically from, a basal flange coupled to the down-roof end of the strap. 
   
   
       14 . The snow guard of  claim 8  wherein the rim is integral with, and extends up-roof from, the snow restraining barrier. 
   
   
       15 . A snow guard for preventing snow from sliding off a roof, the snow guard comprising:
 a longitudinal strap having an up-roof end and a down-roof end;   a snow restraining barrier having a generally arcuate shape with a rim projecting up-roof along the periphery of the snow restraining barrier coupled to the down-roof end of the strap; and   a brace coupled to the down-roof end of the strap supporting the snow restraining barrier   
   
   
       16 . The snow guard of  claim 15  wherein the rim extends orthogonally up-roof along the periphery of the snow restraining barrier. 
   
   
       17 . The snow guard of  claim 15  wherein the snow restraining barrier is a semi-circular disc. 
   
   
       18 . The snow guard of  claim 15  wherein the snow restraining barrier is integral with, and arises vertically from, a basal flange coupled to the down-roof end of the longitudinal strap. 
   
   
       19 . The snow guard of  claim 15  further comprising a plurality of apertures at the up-roof end of the strap to allow the nailing of the snow guard to the roof. 
   
   
       20 . The snow guard of  claim 15  wherein the up-roof end of the longitudinal strap is fixedly secured to the roof. 
   
   
       21 . The snow guard of  claim 15  wherein the up-roof end of the longitudinal strap is fixedly secured to a shingle on the roof. 
   
   
       22 . The snow guard of  claim 15  further comprising at least one aperture in the down-roof end of the strap for allowing seepage of fluid trapped inside the snow restraining barrier. 
   
   
       23 . A snow guard for preventing snow from sliding off a roof, the snow guard comprising:
 a strap having an up-roof end and a down-roof end with at least one aperture in the down-roof end to permit water seepage from one side of the strap to the other;   a snow restraining barrier coupled to the down-roof end of the strap; and   a brace coupled to the down-roof end of the strap supporting the snow restraining barrier;   whereby the aperture in the down-roof end of the strap prevents water build-up inside the brace thereby preventing freeze damage to the brace.   
   
   
       24 . The snow guard of  claim 23  wherein the snow restraining barrier has a generally arcuate shape. 
   
   
       25 . The snow guard of  claim 23  wherein the snow restraining barrier is a semi-circular disc. 
   
   
       26 . The snow guard of  claim 23  further comprising a plurality of apertures at the up-roof end of the strap to allow the nailing of the snow guard to the roof. 
   
   
       27 . The snow guard of  claim 23  wherein the brace is pyramidal in shape with arcuate flanges and lateral flanges projecting in opposite directions.
