Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A sealing member comprising: a resiliently yieldable tubular body having a top wall, a bottom wall and opposite side walls, an internal supporting truss structure within said body and formed integral therewith, said internal truss structure including a pair of cross bars extending downwardly at an angle from said side walls at points spaced below the upper ends thereof to the opposite side walls at points spaced above the lower ends thereof, said cross bars intersecting intermediate their opposite ends, a generally horizontally extending compression bar extending transversely from one of said side walls to the other of said side walls below the intersection of the lower ends of said cross bars with said side walls in spaced relation to said bottom wall for preventing buckling of said side walls upon compression and facilitating the controlled collapse of said body.
Claim 2
Dependent Claim
140 words
A sealing member comprising: a resiliently yieldable tubular body having a top wall, a bottom wall and opposite side walls, an internal supporting truss structure within said body and formed integral therewith, said internal truss structure including a pair of cross bars extending downwardly at an angle from said side walls at points spaced below the upper ends thereof to the opposite side walls at points spaced above the lower ends thereof, said cross bars intersecting intermediate their opposite ends, a generally horizontally extending compression bar extending transversely from one of said side walls to the other of said side walls below the intersection of the lower ends of said cross bars with said side walls in spaced relation to said bottom wall for preventing buckling of said side walls upon compression and facilitating the controlled collapse of said body.
Claim 3
Dependent Claim
42 words
A sealing member according to claim 1 wherein said top wall has downwardly sloping portions forming a V-shaped recess and adapted to fold into the upper space defined by said intersecting cross bars when said side walls are pressed toward each other.
Claim 4
Dependent Claim
41 words
A sealing member according to claim 1 wherein said compression bar includes a pair of angularly related portions extending inwardly and slightly downwardly from said side walls and joined together at a common juncture at an angle slightly less than 180*.
Claim 5
Dependent Claim
30 words
A sealing member according to claim 1 wherein said compression bar defines with said bottom wall an open space into which said compression bar folds upon compression of said body.
Claim 6
Dependent Claim
38 words
A sealing member according to claim 1 wherein said cross bars and said compression bar define with said walls of said body relatively large open spaces into which portions of said sealing member can collapse during compression thereof.
Claim 7
Dependent Claim
75 words
A sealing member according to claim 1 wherein said compression bar includes a pair of angularly related portions extending inwardly and slightly downwardly from said side walls and joined together at a common juncture at an angle slightly less than 180*, said top wall having downwardly sloping portions forming a V-shaped recess and adapted to fold into the upper space defined by said intersecting cross bars when said side walls are pressed toward each other.
Claim 8
Dependent Claim
30 words
A sealing member according to claim 6 wherein said compression bar defines with said bottom wall an open space into which said compression bar folds upon compression of said body.
Claim 9
Dependent Claim
38 words
A sealing member according to claim 7 wherein said cross bars and said compression bar define with said walls of said body relatively large open spaces into which portions of said sealing member can collapse during compression thereof.
Claim 10
Dependent Claim
20 words
A sealing member as set forth in claim 1, wherein said top wall is spaced from said internal truss structure.
