Abstract
Abstract Elongated, hollow elastomer seals particularly useful for sealing concrete pavement contraction joints or longitudinal joints and embodying an elongated, concave top wall, a substantially flat or V-shaped, elongated bottom wall, substantially flat, elongated side walls and an internal web structure consisting essentially of a longitudinally elongated, vertical web joined at its longitudinal edges with and extending between said to and bottom walls substantially midway between said side walls and a pair of longitudinally elongated, diagonal webs extending transversely diagonally downwardly from the upper portion of the vertical web to respective lower portions of said side walls.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
An elongated, hollow seal useful for sealing concrete pavement contraction joints which comprises elongated top, side and bottom elastomer walls forming an elongated, hollow, elastomer sealing strip, said side walls being substantially planar, said top wall being substantially symmetrically, transversely concave and consisting of substantially horizontal outer segments connected by a shallow, V-shaped longitudinal midportion, said bottom wall being V-shaped and joined to the lower edges of said side walls, and an elastomer internal web structure comprising a pair of longitudinally elongated, diagonal webs extending transversely diagonally and symmetrically downwardly from the upper midportion of said upper wall to respective lower edges of said side walls, said diagonal webs being connected in said seal only at their respective longitudinal edges to said upper midportion and to said respective lower edges of said side walls, and a vertical web joined at its longitudinal edges with said V-shaped longitudinal midportion of said top wall and the apex of the V of said bottom wall and extending substantialLy midway between said side walls.
Claim 2
Dependent Claim
170 words
An elongated, hollow seal useful for sealing concrete pavement contraction joints which comprises elongated top, side and bottom elastomer walls forming an elongated, hollow, elastomer sealing strip, said side walls being substantially planar, said top wall being substantially symmetrically, transversely concave and consisting of substantially horizontal outer segments connected by a shallow, V-shaped longitudinal midportion, said bottom wall being V-shaped and joined to the lower edges of said side walls, and an elastomer internal web structure comprising a pair of longitudinally elongated, diagonal webs extending transversely diagonally and symmetrically downwardly from the upper midportion of said upper wall to respective lower edges of said side walls, said diagonal webs being connected in said seal only at their respective longitudinal edges to said upper midportion and to said respective lower edges of said side walls, and a vertical web joined at its longitudinal edges with said V-shaped longitudinal midportion of said top wall and the apex of the V of said bottom wall and extending substantialLy midway between said side walls.
Claim 3
Dependent Claim
195 words
An elongated, hollow, elastomer seal useful for sealing concrete pavement contraction joints which comprises elongated top, side and bottom elastomer walls forming an elongated, hollow, elastomer sealing strip, said side walls being substantially planar, said top wall being substantially symmetrically, transversely concave and consisting of substantially horizontal outer segments connected by a shallow, V-shaped longitudinal midportion, said bottom wall being V-shaped and joined to the lower edges of said side walls, an elastomer internal web structure comprising a pair of longitudinally elongated, diagonal webs extending transversely diagonally and symmetrically downwardly from the upper midportion of said upper wall to respective lower edges of said side walls, said diagonal webs being connected in said seal only at their respective longitudinal edges to said upper midportion and to said respective lower edges of said side walls, a vertical web joined at its longitudinal edges with said V-shaped longitudinal midportion of said top wall and the apex of the V of said bottom wall and extending substantially midway between said side walls, and the upper longitudinal edges of said diagonal webs intersecting said vertical web immediately below the apex of the V-shaped longitudinal midportion of said top wall.
Claim 4
Dependent Claim
