Abstract
Abstract An elastomer joint seal used in modular, slab-like construction for pavements, roads, wall panels and the like. The seal is generally elongated and is placed between facing edges of adjacent modular elements. A pair of spring elements, lodged in the form of an inverted V, runs longitudinally of the seal. By virtue of the internal geometry of the elastomer seal, movement of the modular elements relative to each other strains the spring elements in their respective planes. Two other forms of the seal are disclosed in which one or two additional spring elements are included in the construction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
A seal adapted to be placed between facing edges of adjacent modular units, such as roadbed slabs or wall panels, said seal including a. a pair of spaced, vertically disposed side walls each in the form of a rectangular panel, b. a pair of legs coextensive with said side walls and disposed in the form of a V, the upper ends of said legs secured, respectively, to the upper edges of said side panels, the lower ends of said legs joining to form an apex, said apex positioned between said side walls, c. a pair of spring elements, positioned in the form of an inverted V, the upper edges of said spring elements positioned at and bearing against said apex, the lower edges of said spring elements positioned at the lower edges, respectively, of said side walls, d. whereby movement of the side walls towards each other is accompanied by vertical movement of the apex and compression of the spring members in their own respective planes.
Claim 2
Dependent Claim
166 words
A seal adapted to be placed between facing edges of adjacent modular units, such as roadbed slabs or wall panels, said seal including a. a pair of spaced, vertically disposed side walls each in the form of a rectangular panel, b. a pair of legs coextensive with said side walls and disposed in the form of a V, the upper ends of said legs secured, respectively, to the upper edges of said side panels, the lower ends of said legs joining to form an apex, said apex positioned between said side walls, c. a pair of spring elements, positioned in the form of an inverted V, the upper edges of said spring elements positioned at and bearing against said apex, the lower edges of said spring elements positioned at the lower edges, respectively, of said side walls, d. whereby movement of the side walls towards each other is accompanied by vertical movement of the apex and compression of the spring members in their own respective planes.
Claim 3
Dependent Claim
166 words
A seal adapted to be placed between facing edges of adjacent modular units, such as roadbed slabs or wall panels, said seal including a. a pair of spaced, vertically disposed side walls each in the form of a rectangular panel, b. a pair of legs coextensive with said side walls and disposed in the form of a V, the upper ends of said legs secured, respectively, to the upper edges of said side panels, the lower ends of said legs joining to form an apex, said apex positioned between said side walls, c. a pair of spring elements, positioned in the form of an inverted V, the upper edges of said spring elements positioned at and bearing against said apex, the lower edges of said spring elements positioned at the lower edges, respectively, of said side walls, d. whereby movement of the side walls towards each other is accompanied by vertical movement of the apex and compression of the spring members in their own respective planes.
Claim 4
Dependent Claim
166 words
A seal adapted to be placed between facing edges of adjacent modular units, such as roadbed slabs or wall panels, said seal including a. a pair of spaced, vertically disposed side walls each in the form of a rectangular panel, b. a pair of legs coextensive with said side walls and disposed in the form of a V, the upper ends of said legs secured, respectively, to the upper edges of said side panels, the lower ends of said legs joining to form an apex, said apex positioned between said side walls, c. a pair of spring elements, positioned in the form of an inverted V, the upper edges of said spring elements positioned at and bearing against said apex, the lower edges of said spring elements positioned at the lower edges, respectively, of said side walls, d. whereby movement of the side walls towards each other is accompanied by vertical movement of the apex and compression of the spring members in their own respective planes.
Claim 5
Dependent Claim
16 words
The seal of claim 1 wherein said walls and legs are integral and are of elastomer.
Claim 6
Dependent Claim
13 words
The seal of claim 2 wherein said spring members are of metal wire.
Claim 7
Dependent Claim
91 words
The seal of claim 2 including a second pair of legs coextensive with said side walls, in the form of an inverted V, whose lower ends are secured, respectively, to the lower edges of said side walls and whose upper sides join to form an apex, and a second pair of spring elements disposed in the form of a V, with their upper edges positioned, respectively, at the upper edges of said side walls and their lower edges positioned at and bearing against the Apex of said second pair of legs.
Claim 8
Dependent Claim
16 words
The seal of claim 4 wherein said second pair of spring members are of metal wire.
Claim 9
Dependent Claim
77 words
The seal of claim 1 including a second pair of legs, in the form of an inverted V and coextensive with said side walls, the lower ends of which are secured, respectively, to the lower edges of said side walls and whose upper ends join to form an apex, and a third spring element positioned between the apices of said first and second pair of legs and lying in a vertical plane midway of said side walls.
