Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a pair of cross bars extending downwardly in oppositely inclined directions and intersecting intermediate their opposite ends, and a pair of compression bars extending from said side walls intermediate the upper and lower ends thereof to said cross bars at points between the intersection thereof and the ends thereof, each of said compression bars having angularly related portions formed to facilitate the controlled folding thereof.
Claim 2
Dependent Claim
91 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a pair of cross bars extending downwardly in oppositely inclined directions and intersecting intermediate their opposite ends, and a pair of compression bars extending from said side walls intermediate the upper and lower ends thereof to said cross bars at points between the intersection thereof and the ends thereof, each of said compression bars having angularly related portions formed to facilitate the controlled folding thereof.
Claim 3
Dependent Claim
48 words
A sealing member as set forth in claim 1, said body including top, bottom and opposite side walls, said cross bars extending downwardly at an angle from said top wall to said bottom wall, said compression bars joining said cross bars at points spaced below the intersection thereof.
Claim 4
Dependent Claim
42 words
A sealing member according to claim 2 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 5
Dependent Claim
28 words
A sealing member according to claim 2 wherein said intersecting cross bars define relatively large spaces into which portions of said sealing member can collapse during compression thereof.
Claim 6
Dependent Claim
146 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a plurality of cross bars and a pair of compression bars, each having angularly related portions formed to facilitate the controlled folding thereof, said body including top, bottom and opposite side walls, said truss structure including a pair of cross bars extending downwardly at an angle from said top wall to said bottom wall, said cross bars intersecting intermediate their opposite ends, said compression bars extending from said side walls intermediate the upper and lower ends thereof tO said cross bars at points spaced below the intersection thereof, said side walls terminating at said top and bottom walls, respectively, to form corners therewith, and said intersecting cross bars terminating at said top and bottom walls slightly inwardly of said corners.
Claim 7
Dependent Claim
146 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a plurality of cross bars and a pair of compression bars, each having angularly related portions formed to facilitate the controlled folding thereof, said body including top, bottom and opposite side walls, said truss structure including a pair of cross bars extending downwardly at an angle from said top wall to said bottom wall, said cross bars intersecting intermediate their opposite ends, said compression bars extending from said side walls intermediate the upper and lower ends thereof tO said cross bars at points spaced below the intersection thereof, said side walls terminating at said top and bottom walls, respectively, to form corners therewith, and said intersecting cross bars terminating at said top and bottom walls slightly inwardly of said corners.
Claim 8
Dependent Claim
156 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a plurality of cross bars and a pair of compression bars having angularly related portions formed to facilitate the controlled folding thereof, said body including top, bottom and opposite side walls, said truss structure including a pair of cross bars extending downwardly at an angle from said top wall to said bottom wall, said cross bars intersecting intermediate their opposite ends, said compression bars extending from said side walls intermediate the upper and lower ends thereof to said cross bars at points spaced below the intersection thereof, said compression bars being angularly bent and having first portions extending from said cross bars in directions generally normal thereto and second portions extending from said first portions upwardly at an angle to said side walls intermediate the upper and lower ends thereof.
Claim 9
Dependent Claim
156 words
In a sealing member a resiliently yieldable tubular body, and an internal supporting truss structure within said body formed integral therewith, said internal truss structure including a plurality of cross bars and a pair of compression bars having angularly related portions formed to facilitate the controlled folding thereof, said body including top, bottom and opposite side walls, said truss structure including a pair of cross bars extending downwardly at an angle from said top wall to said bottom wall, said cross bars intersecting intermediate their opposite ends, said compression bars extending from said side walls intermediate the upper and lower ends thereof to said cross bars at points spaced below the intersection thereof, said compression bars being angularly bent and having first portions extending from said cross bars in directions generally normal thereto and second portions extending from said first portions upwardly at an angle to said side walls intermediate the upper and lower ends thereof.
