Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
A sealing member comprising a resiliently yeildable, hollow tubular body, and a generally T-shaped formation formed integral with said body and having laterally extending wings overlying said tubular body in spaced relation thereto, said tubular body having a top wall, a bottom wall and opposite side walls and said T-shaped formation being joined to said top wall, said tubular body further including a pair of internal cross bars extending downwardly at an angle from the upper portions of said side walls at points spaced below the ends thereof to the lower portions of the opposite ones of said side walls at points spaced above the ends thereof and in supporting relation thereto, said cross bars intersecting intermediate their opposite ends, and said tubular body further including a 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 a spaced relation to said bottom wall for preventing buckling of said side walls upon compression thereof and facilitating the controlled collapse of said body and 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 2
Dependent Claim
220 words
A sealing member comprising a resiliently yeildable, hollow tubular body, and a generally T-shaped formation formed integral with said body and having laterally extending wings overlying said tubular body in spaced relation thereto, said tubular body having a top wall, a bottom wall and opposite side walls and said T-shaped formation being joined to said top wall, said tubular body further including a pair of internal cross bars extending downwardly at an angle from the upper portions of said side walls at points spaced below the ends thereof to the lower portions of the opposite ones of said side walls at points spaced above the ends thereof and in supporting relation thereto, said cross bars intersecting intermediate their opposite ends, and said tubular body further including a 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 a spaced relation to said bottom wall for preventing buckling of said side walls upon compression thereof and facilitating the controlled collapse of said body and 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 3
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 4
Dependent Claim
38 words
A sealing member according to claim 1 wherein said cross bars and said compression bar define with side walls of said body relatively large open spaces into which portions of said sealing member can collapse during compression thereof.
Claim 5
Dependent Claim
55 words
A sealing member as set forth in claim 1 wherein said top wall has a first pair of upwardly sloping portions extending inwardly from said side walls and a second pair of upwardly sloping portions extending inwardly from said first pair of sloping portions in a converging relation and joined together at a common juncture.
Claim 6
Dependent Claim
21 words
A sealing member as set forth in claim 4 wherein said common juncture includes a hollow portion throughout for added flexibility.
