Abstract
Abstract An elongated resiliently yieldable sealing member for use in an expansion joint comprising a pair of side sections and a flexible intermediate section interposed between and formed integral with the side sections. The intermediate section has a flexible internal truss structure which is readily compressible and which accommodates movements in various planes while maintaining sealing pressure against adjoining structural members. The outer surfaces of the side sections conform to the flanges of standard structural members.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
88 words
A sealing member comprising: an elongated, elastic body having a pair of side sections and an intermediate section interposed between and formed integral with said side sections, said intermediate section comprising a plurality of cross bars intersecting intermediate the opposite ends thereof and collapsing upon movement of said side sections toward each other during compression of said body, each of said side sections comprising a tubular structure and an internal truss structure for increased relative rigidity preventing substantial buckling thereof until said intermediate section is substantially fully collapsed.
Claim 2
Dependent Claim
88 words
A sealing member comprising: an elongated, elastic body having a pair of side sections and an intermediate section interposed between and formed integral with said side sections, said intermediate section comprising a plurality of cross bars intersecting intermediate the opposite ends thereof and collapsing upon movement of said side sections toward each other during compression of said body, each of said side sections comprising a tubular structure and an internal truss structure for increased relative rigidity preventing substantial buckling thereof until said intermediate section is substantially fully collapsed.
Claim 3
Dependent Claim
16 words

Claim 4
Dependent Claim
68 words
A sealing member according to claim 1, wherein each of said side sections has a pair of side walls joined at the opposite ends thereof to top and bottom walls to form a tubular structure, said internal truss structure of each of said side sections comprising a pair of angularly related bars forming a diamond shaped configuration and extending between said side walls intermediate the opposite ends thereof.
Claim 5
Dependent Claim
29 words
A sealing member according to claim 1 wherein said side sections have top and bottom walls each comprising a pair of sloping portions joined together to form a corner.
Claim 6
Dependent Claim
61 words
A sealing member according to claim 4 wherein said side sections also have inner and outer side walls, said internal truss structure of each of said side sections including a pair of diagonal bars extending inwardly in diverging relation from said outer side wall intermediate the opposite ends thereof and joined to said top and bottom walls, respectively, adjacent said corners.
Claim 7
Dependent Claim
47 words
A sealing member according to claim 1 wherein said side sections have outer side walls and top and bottom wall portions extending inwardly in diverging relation from said outer side walls adjacent the opposite ends thereof to fit standard structural members and form a mechanical lock therewith.
Claim 8
Dependent Claim
38 words
A sealing member accordIng to claim 6 wherein the exterior surfaces of said outer side walls and said top and bottom wall portions are provided with means for retaining and trapping an adhesive applied to said exterior surfaces.
Claim 9
Dependent Claim
20 words
A sealing member according to claim 1, wherein said intermediate section is joined to said side sections at spaced points.
Claim 10
Dependent Claim
33 words
A sealing member according to claim 1 wherein said intermediate section comprises a corrugated top wall and a corrugated bottom wall joined at the respective opposite ends there of to said side sections.
Claim 11
Dependent Claim
61 words
A sealing member according to claim 9 wherein said interconnecting cross bars of said intermediate section extend from said corrugated top wall downwardly to said corrugated bottom wall, adjacent pairs of said cross bars being interconnected adjacent their opposite ends, and the outermost pairs thereof being connected adjacent their outer ends to said side sections to form a collapsible pantograph arrangement.
Claim 12
Dependent Claim
82 words
A sealing member according to claim 1, wherein said side sections comprise outer side walls, top and bottom walls having major portions extending inwardly in diverging relation from opposite ends of said outer walls and minor portions extending inwardly in converging relation from the outer ends of said major portions thereof, and inner side walls generally parallel to said outer side walls interconnecting the outer ends of said minor top wall portions, said side, top and bottom walls defining said tubular structures.
Claim 13
Dependent Claim
67 words
A sealing member according to claim 11, wherein said major and minor portions of said top and bottom walls form corners at the junctures thereof, and wherein said internal truss structure of each of said side sections includes a pair of diagonal bars extending inwardly in diverging relation from said outer side wall intermediate the opposite ends thereof to said top and bottom walls adjacent said corners.
Claim 14
Dependent Claim
44 words
A sealing member according to claim 12, wherein said internal truss structure of each of said side sections includes angularly related bars extending between said side walls and jointed thereto intermediate the opposite ends thereof, said angularly related bars forming a diamond shaped configuration.
Claim 15
Dependent Claim
36 words
A sealing member according to claim 11 wherein the outermost ends of the outermost pair of said intermediate section cross bars are connected to said side structure adjacent the outer ends of said minor portions thereof.
Claim 16
Dependent Claim
35 words
