Abstract
Abstract Invertible, elongated, elastomer joint sealing strips having substantially flat sidewalls, longitudinally corrugated or pleated top and bottom walls preferably of the same general configuration, and an internal web structure with one or two pairs of crossed webs connected to the top and bottom walls and additional diagonal webs extending diagonally across the four corners to provide two or three side-by-side diamond openings in internal structure of seals.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
93 words
An elongated, elastomer, joint-sealing strip comprising an elongated hollow body defined by substantially planar sidewalls, a top wall of substantially shallow W-configuration, a bottom wall of substantially shallow M-configuration, the nadirs of said W-configuration of the top wall being opposite the apices of said M-configuration of the bottom wall, a pair of diagonal webs connected to the nadirs of the top wall and to the apices of the bottom wall and crossing at the centers thereof, and additional diagonal webs connected respectively to said nadirs and apices and the midportions of contiguous sidewalls.
Claim 2
Dependent Claim
93 words
An elongated, elastomer, joint-sealing strip comprising an elongated hollow body defined by substantially planar sidewalls, a top wall of substantially shallow W-configuration, a bottom wall of substantially shallow M-configuration, the nadirs of said W-configuration of the top wall being opposite the apices of said M-configuration of the bottom wall, a pair of diagonal webs connected to the nadirs of the top wall and to the apices of the bottom wall and crossing at the centers thereof, and additional diagonal webs connected respectively to said nadirs and apices and the midportions of contiguous sidewalls.
Claim 3
Dependent Claim
24 words
A joint-sealing strip as claimed in claim 1 wherein said top wall and bottom wall are joined respectively with said sidewalls by rounded corners.
Claim 4
Dependent Claim
29 words
A joint-sealing strip as claimed in claim 1 wherein said diagonal webs are joined at their longitudinal edges directly to said apices and nadirs and also to said sidewalls.
Claim 5
Dependent Claim
35 words
A joint sealing strip as claimed in claim 1 wherein said diagonal webs are joined at their longitudinal edges directly to the sidewalls and by narrow, vertical, elastomer webs to said top and bottom walls.
Claim 6
Dependent Claim
140 words
An elongated, elastomer, joint-sealing strip comprising an elongated hollow body defined by substantially planar sidewalls, a top wall having a midportion of shallow-M-configuration with the edges of said midportion joined with the sidewalls by upwardly sloping strips, a bottom wall having a midportion of shallow-W-configuration with the edges of the latter midportion joined with said sidewalls by downwardly sloping strips, the three nadirs and two apices of said top wall being respectively opposite the three apices and two nadirs of the bottom wall, two pairs of diagonal web structures crossing at the centers thereof and extending diagonally from the nadirs of the top wall to the apices of the bottom wall, and additional diagonal webs extending from the two outer nadirs of said top wall and the two outer apices of the bottom wall to the midportion of contiguous sidewalls.
Claim 7
Dependent Claim
140 words
An elongated, elastomer, joint-sealing strip comprising an elongated hollow body defined by substantially planar sidewalls, a top wall having a midportion of shallow-M-configuration with the edges of said midportion joined with the sidewalls by upwardly sloping strips, a bottom wall having a midportion of shallow-W-configuration with the edges of the latter midportion joined with said sidewalls by downwardly sloping strips, the three nadirs and two apices of said top wall being respectively opposite the three apices and two nadirs of the bottom wall, two pairs of diagonal web structures crossing at the centers thereof and extending diagonally from the nadirs of the top wall to the apices of the bottom wall, and additional diagonal webs extending from the two outer nadirs of said top wall and the two outer apices of the bottom wall to the midportion of contiguous sidewalls.
Claim 8
Dependent Claim
44 words
A joint-sealing strip as claimed in claim 5 wherein said additional diagonal webs are joined at their longitudinal edges directly to said sidewalls, and said additional webs and said webs of said pairs are joined to said apices and nadirs by narrow, vertical webs.
