Abstract
Abstract A device for protecting a tarpaulin from damage, as it passes over the sharp corner of a load, which is mounted on a flat bed truck, or other transporting device. The protective device comprises three planar sides and a rounded corner, it is inserted between the load and the tarpaulin, at the corner of the load, and prevents direct bearing of the tarpaulin upon the sharp corner of the load.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
The combination comprising: a first structure having at least one corner; a second structure comprising three substantially planar sides, each side being substantially perpendicular to the other sides of said second structure, such that all three sides converge toward a vertex, a blunting means being formed at said vertex, said second structure being removably placed over said first structure so that said blunting means is located over said corner; and covering means draped over said first and second structures so that said blunting means causes stress in said covering means to be evenly distributed, thereby preventing tears in said covering means, said second structure being held in place by said covering means, such that if said covering means is removed, said second structure can be lifted off said first structure.
Claim 2
Dependent Claim
130 words
The combination comprising: a first structure having at least one corner; a second structure comprising three substantially planar sides, each side being substantially perpendicular to the other sides of said second structure, such that all three sides converge toward a vertex, a blunting means being formed at said vertex, said second structure being removably placed over said first structure so that said blunting means is located over said corner; and covering means draped over said first and second structures so that said blunting means causes stress in said covering means to be evenly distributed, thereby preventing tears in said covering means, said second structure being held in place by said covering means, such that if said covering means is removed, said second structure can be lifted off said first structure.
Claim 3
Dependent Claim
14 words
Combination as recited in claim 1, wherein said second structure is of molded thermoplastic.
Claim 4
Dependent Claim
28 words
Combination of claim 1 wherein said second structure is substantially shaped as a right triangular pyramid, and said first structure is a load placed on a transport means.
Claim 5
Dependent Claim
18 words
Combination as recited in claim 3, wherein said blunting means is a dome shape which intersects said pyramid.
Claim 6
Dependent Claim
22 words
Combination of claim 1 wherein said covering means is a tarpaulin and said blunting means is a dome formed at said vertex.
Claim 7
Dependent Claim
34 words
Combination as recited in claim 1, wherein the second structure is constructed of foamed plastic, and said blunting means is formed by a general thickening and rounding of the intersecting sides at the vertex.
Claim 8
Dependent Claim
47 words
Combination as recited in claim 1, wherein said second structure is an open shape and (a) said three sides form the inside surface of said open shape, and (b) said blunting means is formed by a general spherical shape forming the exterior surface of said open shape.
Claim 9
Dependent Claim
27 words
The combination of claim 1 wherein the inside surface of said second structure has raised ribs to enhance gripping of said second structure to said first structure.
Claim 10
Independent Claim
104 words
A method for protecting a tarpaulin comprising the steps of: providing a first structure having at least one corner; removably placing over said corner a second structure having three substantially planar sides, each side being substantially perpendicular to the other sides such that all three sides converge to a vertex, said vertex being placed over said corner, said second structure including blunting means formed at said vertex; and draping covering means over said first and second structures, such that said blunting means prevents said covering means from being torn by said corner, and such that said covering means holds said second structure in place.
Claim 11
Independent Claim
104 words
A method for protecting a tarpaulin comprising the steps of: providing a first structure having at least one corner; removably placing over said corner a second structure having three substantially planar sides, each side being substantially perpendicular to the other sides such that all three sides converge to a vertex, said vertex being placed over said corner, said second structure including blunting means formed at said vertex; and draping covering means over said first and second structures, such that said blunting means prevents said covering means from being torn by said corner, and such that said covering means holds said second structure in place.
Claim 12
Dependent Claim
28 words
The method of claim 9 wherein said first structure is a load placed on a transport means and said second structure is shaped as a right triangular pyramid.
Claim 13
Dependent Claim
23 words
The method of claim 9 wherein said covering means is a tarpaulin and said blunting means is a dome formed at said vertex.
Claim 14
Dependent Claim
13 words
The method of claim 9 wherein said second structure is of molded thermoplastic.
