Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
137 words
A joint which is sealed by having compressed between opposed faces of said joint an elastomer seal which in the uncompressed state comprises an elongated, elastomer, regular hexagonal tube having equal sides and equal angles having therein three inner, crossed webs extending across the tube and intersecting at their midpoints, the outer edges of the respective crossed webs intersecting and being integral with the respective six sides of said tube substantially along the respective longitudinal midlines of said sides, said seal in the compressed state between said faces having flattened, planar side walls, each side wall consisting of a pair of adjacent sides of said hexagon with the webs intersecting the four respective sides being bent, and the opposite two remaining sides of the hexagon having radially inward folds with the respective webs connected thereto being straight.
Claim 2
Dependent Claim
137 words
A joint which is sealed by having compressed between opposed faces of said joint an elastomer seal which in the uncompressed state comprises an elongated, elastomer, regular hexagonal tube having equal sides and equal angles having therein three inner, crossed webs extending across the tube and intersecting at their midpoints, the outer edges of the respective crossed webs intersecting and being integral with the respective six sides of said tube substantially along the respective longitudinal midlines of said sides, said seal in the compressed state between said faces having flattened, planar side walls, each side wall consisting of a pair of adjacent sides of said hexagon with the webs intersecting the four respective sides being bent, and the opposite two remaining sides of the hexagon having radially inward folds with the respective webs connected thereto being straight.
Claim 3
Dependent Claim
39 words
A joint as claimed in claim 1 wherein said joint is a pavement joint between contiguous slabs of pavement, said faces being the opposed sides of the contiguous slabs of pavement which are spaced to form said pavement joint.
Claim 4
Dependent Claim
