Abstract

A roof anchor including a pair of blocks positioned side-by-side. The blocks have adjacent, inner surfaces with notches cut therefrom for receiving a standing seam of a metal roof. The blocks also have outer surfaces remote from the inner surfaces. A bracket is positioned over the pair of blocks. The bracket includes a base portion having a pair of legs, each being positioned adjacent a respective one of the outer surfaces of the blocks, and a crosspiece, positioned adjacent the tops of the blocks, joining the legs together. A loop portion is affixed to the base portion for securement of a workman'"'"'s safety lanyard. A threaded fastener penetrates the pair of blocks and the pair of legs for: fastening the pair of blocks together, securing the bracket to the pair of blocks, and clamping the pair of blocks upon a standing seam of a metal roof.

Claims

1. A roof anchor, comprising:

a pair of blocks positioned side-by-side, said blocks having adjacent, inner surfaces with notches cut therefrom for receiving a standing seam of a metal roof, said blocks also having outer surfaces remote from said inner surfaces;

a bracket positioned over said pair of blocks, said bracket including;

a base portion having a pair of legs, each positioned adjacent a respective one of said outer surfaces, and a crosspiece, positioned adjacent the tops of said blocks, joining said legs; and

,

a loop portion affixed to said base portion for securement of a safety lanyard;

a threaded fastener penetrating said pair of blocks and said pair of legs for;

fastening said pair of blocks together, securing said bracket to said pair of blocks, and clamping said pair of blocks upon a standing seam of a metal roof.

2. The roof anchor according to claim 1 further comprising a pair of alignment pins positioned away from each other and said fastener, each of said alignment pins having opposed ends extending through said notches and penetrating said pair of blocks.

3. A roof anchor, comprising:

a pair of blocks positioned side-by-side, each of said blocks having an inner surface defined by a top flange and a bottom flange separated by a notch for receiving a standing seam of a metal roof, each of said blocks also having an outer surface;

a bracket including;

a base portion having a pair of legs, each positioned adjacent one said outer surface, and a crosspiece, positioned adjacent the tops of said blocks, joining said legs; and

,

a loop portion affixed to said crosspiece for securement of a safety lanyard; and

,

a threaded fastener penetrating each one of said blocks between said top flange and said bottom flange thereof and said pair of legs for;

fastening said pair of blocks together, securing said bracket to said pair of blocks, and clamping said bottom flanges against opposite sides of a standing seam of a metal roof.

4. The roof anchor according to claim 3 further comprising a pair of alignment pins positioned away from each other and said fastener, each of said alignment pins having opposed ends extending through said notches and penetrating said pair of blocks above said bottom flanges thereof.

5. A roof anchor, comprising:

a pair of blocks positioned side-by-side, each of said blocks having an inner surface defined by a top flange and a bottom flange separated by a triangular notch for receiving a standing seam of a metal roof, each of said blocks also having an outer surface;

a bracket including;

a base portion having a pair of legs, each positioned adjacent said outer surface of each of said blocks, and a crosspiece joining said legs; and

,

a loop portion affixed to said crosspiece for securement of a safety lanyard;

a plurality of threaded fasteners penetrating each one of said blocks above said bottom flange thereof for fastening said pair of blocks together and clamping said bottom flanges against opposite sides of a standing seam of a metal roof, and one of said threaded fasteners penetrating said pair of legs for securing said bracket to said pair of blocks; and

,

a pair of alignment pins positioned away from each other and said threaded fasteners, each of said alignment pins having opposed ends extending through said notches and penetrating said pair of blocks above said bottom flanges thereof.
