Safety system for roofs and related methods

Abstract

A safety system for a building roof may include a plurality of anchors to be connected to the building roof at spaced apart locations, at least one frame member, a net connected to the at least one frame member, and a plurality of straps each defining a loop extending between a respective anchor and the at least one frame member, with a portion of the loop being connected to the net. The safety system may further include a plurality of standoff members to be positioned between the building roof and the at least one frame member at spaced apart locations to hold the at least one frame member away from the building roof, and disengage from the building roof when the net is under load so that the net wraps around the load and the straps hang from the anchors.

1 . A safety system for a building roof, the safety system comprising:
 a plurality of anchors to be connected to the building roof at spaced apart locations;   at least one frame member;   a net connected to the at least one frame member;   a plurality of straps each defining a loop extending between a respective anchor and the at least one frame member, a portion of the loop being connected to the net; and   a plurality of standoff members to be positioned between the building roof and the at least one frame member at spaced apart locations to hold the at least one frame member away from the building roof, and disengage from the building roof when the net is under load so that the net wraps around the load and the straps hang from the anchors.   
     
     
         2 . The safety system of  claim 1  wherein the anchors comprise anchor rings. 
     
     
         3 . The safety system of  claim 1  wherein the anchors comprise roof ridge hooks. 
     
     
         4 . The safety system of  claim 1  wherein the bottom portions of the straps loop are connected to the net across a surface thereof. 
     
     
         5 . The safety system of  claim 1  wherein the standoff members are jointed. 
     
     
         6 . The safety system of  claim 1  wherein the at least one frame member comprises a first frame member connected to a first side of the net and a second frame member connected to a second side of the net opposite the first side, the first frame member to be positioned adjacent the building roof and the second frame member to be held away from the building roof by the standoff members. 
     
     
         7 . The safety system of  claim 1  wherein the standoff members comprise at least one of polyvinyl chloride (PVC), metal strips, and wood. 
     
     
         8 . A safety device for a building having a building roof, the safety device comprising:
 at least one frame member;   a net connected to the at least one frame member;   a plurality of straps each defining a loop extending between a respective anchor connected to the building roof and the at least one frame member, a portion of the loop being connected to the net; and   a plurality of standoff members to be positioned between the building roof and the at least one frame member at spaced apart locations to hold the at least one frame member away from the building roof, and disengage from the building roof when the net is under load so that the net wraps around the load and the straps hang from the anchors.   
     
     
         9 . The safety device of  claim 8  wherein the anchors comprise anchor rings. 
     
     
         10 . The safety device of  claim 8  wherein the anchors comprise roof ridge hooks. 
     
     
         11 . The safety device of  claim 8  wherein the bottom portions of the strap loops are connected to the net across a surface thereof. 
     
     
         12 . The safety device of  claim 8  wherein the standoff members are jointed. 
     
     
         13 . The safety device of  claim 8  wherein the at least one frame member comprises a first frame member connected to a first side of the net and a second frame member connected to a second side of the net opposite the first side, the first frame member to be positioned adjacent the building roof and the second frame member to be held away from the building roof by the standoff members. 
     
     
         14 . The safety device of  claim 8  wherein the standoff members comprise at least one of polyvinyl chloride (PVC), metal strips, and wood. 
     
     
         15 . A method comprising:
 connecting a plurality of anchors to a building roof at spaced apart locations;   connecting a plurality of straps each to a respective anchor, each strap defining a loop extending between the respective anchor and at least one frame member, and a portion of the loop being connected to a net; and   positioning a plurality of standoff members between the building roof and the at least one frame member at spaced apart locations to hold the at least one frame member away from the building roof, and disengage from the building roof when the net is under load so that the net wraps around the load and the straps hang from the anchors.   
     
     
         16 . The method of  claim 15  wherein the anchors comprise anchor rings. 
     
     
         17 . The method of  claim 15  wherein the anchors comprise roof ridge hooks. 
     
     
         18 . The method of  claim 15  wherein the bottom portions of the strap loops are connected to the net across a surface thereof. 
     
     
         19 . The method of  claim 15  wherein the standoff members are jointed. 
     
     
         20 . The method of  claim 15  wherein the at least one frame member comprises a first frame member connected to a first side of the net and a second frame member connected to a second side of the net opposite the first side; and wherein positioning further comprises positioning the first frame member adjacent the building roof and the second frame member so that it is held away from the building roof by the standoff members.
