Abstract
Abstract A multiple use shim product having plural rows of spaced-apart shims, with the shims being integrally-connected to adjacent shims in the same row as well as adjacent rows by relatively thin and narrow fracturable hinge sections. The shim product is of a one-piece construction formed as a molded sheet of plastic material. Each shim is of generally a horseshoe shape with a space between separated legs. The shims are arranged in adjacent rows wherein separation of two particular rows of shims from the sheet can have the shim spaces opening outwardly from each row of shims and another selection of rows of shims can have the shim leg sections abutting to form an elongate enclosed opening by the combined spaces.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A versatile multiple use shim product comprising, a molded sheet of plastic material having a plurality of rows of shims with each shim having a pair of legs with an opening therebetween and integrally connected to adjacent shims in the same row as well as adjacent rows by relatively thin and narrow fracturable hinge sections of said plastic material; and the shims in at least two adjacent rows of shims being arranged in a mirror-image relation to have the openings of opposed shims in the adjacent rows define an elongate enclosed opening.
Claim 2
Dependent Claim
92 words
A versatile multiple use shim product comprising, a molded sheet of plastic material having a plurality of rows of shims with each shim having a pair of legs with an opening therebetween and integrally connected to adjacent shims in the same row as well as adjacent rows by relatively thin and narrow fracturable hinge sections of said plastic material; and the shims in at least two adjacent rows of shims being arranged in a mirror-image relation to have the openings of opposed shims in the adjacent rows define an elongate enclosed opening.
Claim 3
Dependent Claim
27 words
A shim product as defined in claim 1 wherein an outside row of shims has the openings between the legs open to the edge of the sheet.
Claim 4
Dependent Claim
84 words
A versatile multiple use shim product comprising, a molded sheet of plastic material having a plurality of rows of shims with each shim having a pair of legs with an opening therebetween and integrally connected to adjacent shims in the same row as well as adjacent rows by relatively thin and narrow fracturable hinge sections of said plastic material; and the shims in at least two of said rows are associated in mirror-image relation whereby the openings of opposed shims extend in opposite directions.
Claim 5
Dependent Claim
84 words
A versatile multiple use shim product comprising, a molded sheet of plastic material having a plurality of rows of shims with each shim having a pair of legs with an opening therebetween and integrally connected to adjacent shims in the same row as well as adjacent rows by relatively thin and narrow fracturable hinge sections of said plastic material; and the shims in at least two of said rows are associated in mirror-image relation whereby the openings of opposed shims extend in opposite directions.
Claim 6
Dependent Claim
48 words
A shim product as defined in claim 3 wherein each shim has a base section from which said legs extend and said fracturable hinge sections are integrally formed between the base sections of said opposed shims and between the outer edges of the legs of said opposed shims.
Claim 7
Dependent Claim
152 words
a multiple use shim product comprising, a molded one-piece sheet of a plastic material such as polystyrene or polypropylene or the like having spaced-apart plural rows of spaced-apart shims with each shim having a shape resembling a horseshoe with a base section and pair of spaced-apart legs having a space therebetween, at least two adjacent rows of said shims having opposed shims in a mirror-image relation whereby the ends of the legs of opposed shims are adjacent each other and the spaces thereof define a common opening, at least one row of shims at the edge of the sheet having the spaces thereof open to the perimeter of the sheet and integral fracturable hinge sections holding said rows of shims together in sheet from and enabling either folding of shims onto each other to form a pad or separation of a selected number of shims or rows of shims from said sheet.
Claim 8
Dependent Claim
152 words
a multiple use shim product comprising, a molded one-piece sheet of a plastic material such as polystyrene or polypropylene or the like having spaced-apart plural rows of spaced-apart shims with each shim having a shape resembling a horseshoe with a base section and pair of spaced-apart legs having a space therebetween, at least two adjacent rows of said shims having opposed shims in a mirror-image relation whereby the ends of the legs of opposed shims are adjacent each other and the spaces thereof define a common opening, at least one row of shims at the edge of the sheet having the spaces thereof open to the perimeter of the sheet and integral fracturable hinge sections holding said rows of shims together in sheet from and enabling either folding of shims onto each other to form a pad or separation of a selected number of shims or rows of shims from said sheet.
Claim 9
Dependent Claim
26 words
A shim product as defined in claim 5 wherein said hinge sections interconnect the adjacent base sections of a plurality of adjacent shims in adjacent rows.
Claim 10
Dependent Claim
22 words
A shim product as defined in claim 6 wherein there are hinge sections between adjacent legs of a second plurality of shims.
