Abstract
Abstract Elongated, hollow elastomer seals particularly useful for the sealing of concrete pavement joints, bridge deck joints, etc. against intrusion by liquids and incompressible solids and embodying bottom wall; substantially flat, elongated sidewalls; and an internal, thrust structure or network having elongated, downwardly diverging webs in the transversely median portion of the network and diverging from an apex at or below the longitudinal midportion of the top wall and one or more pairs of elongated, transversely laterally extending webs extending between the diverging webs and respective sidewalls.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
132 words
A hollow, elongated elastomer seal useful for sealing pavement joints and bridge joints comprising an elongated, hollow elastomer body having a substantially V-shaped top wall, substantially paralLel sidewalls and a bottom wall joined to said sidewalls and configured to assume a progressively deeper concave shape upon lateral compression of said seal, and an internal web structure including a pair of laterally diverging webs having an apex portion joined to the nadir of said substantially V-shaped top wall, the lower ends of said diverging webs being joined to said bottom wall inwardly from the junctures of said bottom wall and said sidewalls in position to pull said diverging legs downwardly as said seal is laterally collapsed, and a pair of additional, lateral web members connecting said laterally diverging webs to a contiguous sidewall.
Claim 2
Dependent Claim
132 words
A hollow, elongated elastomer seal useful for sealing pavement joints and bridge joints comprising an elongated, hollow elastomer body having a substantially V-shaped top wall, substantially paralLel sidewalls and a bottom wall joined to said sidewalls and configured to assume a progressively deeper concave shape upon lateral compression of said seal, and an internal web structure including a pair of laterally diverging webs having an apex portion joined to the nadir of said substantially V-shaped top wall, the lower ends of said diverging webs being joined to said bottom wall inwardly from the junctures of said bottom wall and said sidewalls in position to pull said diverging legs downwardly as said seal is laterally collapsed, and a pair of additional, lateral web members connecting said laterally diverging webs to a contiguous sidewall.
Claim 3
Dependent Claim
26 words
An elastomer seal as claimed in claim 1 wherein said apex portion of said diverging webs is joined directly with said nadir of said top wall.
Claim 4
Dependent Claim
48 words
An elastomer seal as claimed in claim 1 wherein said apex portion of said diverging webs is joined with said nadir of said top wall by a vertical web substantially midway between said sidewalls and having its longitudinal edges respectively joined with said apex portion and said nadir.
Claim 5
Dependent Claim
35 words
An elastomer seal as claimed in claim 1 wherein said additional web members are joined at their respective longitudinal edges with respective diverging webs at points near but below the apex of said diverging webs.
Claim 6
Dependent Claim
25 words
An elastomer seal as claimed in claim 1 wherein said seal has a plurality of pairs of said additional web members in vertically spaced relationship.
Claim 7
Dependent Claim
24 words
An elastomer seal as claimed in claim 5 wherein said seal has at least one further web extending substantially horizontally between said diverging webs.
Claim 8
Dependent Claim
24 words
An elastomer seal as claimed in claim 1 wherein said seal has at least one further web extending substantially horizontally between said diverging webs.
Claim 9
Dependent Claim
17 words
An elastomer seal as claimed in claim 1 wherein said bottom wall is a substantially V-shaped wall.
Claim 10
Dependent Claim
17 words
An elastomer seal as claimed in claim 1 wherein said bottom wall is a substantially planar wall.
