Abstract
Abstract A reinforcing patch for reinforcing an opening through sheet material including a pair of spaced plate members interconnected by a hinge member to form a U-shaped reinforcing patch and with a pair of openings extending in line through both plate members and with a plurality of teeth extending inwardly from each plate member and with the teeth spaced around the periphery of the opening in each plate member. The plate members are positioned on opposite sides of the sheet material and with the teeth extending into the opening through the sheet material. The invention also includes the use of a loop member integral with and extending from the hinge member. In addition, the teeth may abut each other in the opening or the teeth may interlock within the opening through the sheet material.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
150 words
A reinforcing patch for reinforcing an opening through sheet material, including a pair of spaced plate members interconnected along a first side portion by a hinge member to form a U-shaped reinforcing patch, a pair of openings extending in line through both plate members, a plurality of teeth extending inwardly from each plate member and spaced around the periphery of the openings in each plate member and with the outer configuration formed by the plurality of teeth spaced around the opening in each plate member conforming to the configuration of the opening through the sheet material to have the spaced plate members positioned in opposite sides of the sheet material and with the teeth extending into the opening through the sheet material and with the teeth flexible to bend away when the reinforcing patch is slipped over the sheet material and to snap into the opening through the sheet material.
Claim 2
Dependent Claim
150 words
A reinforcing patch for reinforcing an opening through sheet material, including a pair of spaced plate members interconnected along a first side portion by a hinge member to form a U-shaped reinforcing patch, a pair of openings extending in line through both plate members, a plurality of teeth extending inwardly from each plate member and spaced around the periphery of the openings in each plate member and with the outer configuration formed by the plurality of teeth spaced around the opening in each plate member conforming to the configuration of the opening through the sheet material to have the spaced plate members positioned in opposite sides of the sheet material and with the teeth extending into the opening through the sheet material and with the teeth flexible to bend away when the reinforcing patch is slipped over the sheet material and to snap into the opening through the sheet material.
Claim 3
Dependent Claim
25 words
The reinforcing patch of claim 1 wherein the hinge member is formed of plastic and including an integral plastic loop extending from the hinge member.
Claim 4
Dependent Claim
21 words

Claim 5
Dependent Claim
20 words
The reinforcing patch of claim 1 wherein the plate members, hinge member and teeth are all integrally formed from plastic.
Claim 6
Dependent Claim
19 words

Claim 7
Dependent Claim
35 words
The reinforcing patch of claim 1 wherein the outer configurations formed by the plurality of teeth on each plate member are substantially identical to have the teeth abut when the plate members are flexed inwardly.
Claim 8
Dependent Claim
32 words
The reinforcing patch of claim 1 wherein the teeth on one plate member are designed to interlock with the teeth on the other plate member when the plate members are flexed inwardly.
