Abstract

Abstract The present expansion gap sealing device has a plurality of rigid strips and elastomeric strips between adjacent rigid strips which extend longitudinally through the gap. The strips are supported by legs extending downwardly into the gap. Upper ends of the legs are connected to the rigid strips. Lower ends of the legs are interconnected with each other in pairs whereby adjacent legs form a pair and an elastically yielding structure. The lower leg ends may be interconnected by bars.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 109 words
An expansion gap sealing device for bridging an expansion gap between edges of structural members, comprising rigid strips and compressible strips arranged in an alternating manner and extending alongside each other and longitudinally inside the gap to form an expansion and sealing assembly having outer sides connected to the edges of the gap, supporting structure means comprising rod-like legs having upper ends connected to said rigid strips, said legs extending and converging downwardly into the gap, said legs having lower ends, and lower means connecting said lower ends of the legs to form springy pairs of legs elastically supporting said assembly in response to the movement of said edges.
Claim 2
Dependent Claim 109 words
An expansion gap sealing device for bridging an expansion gap between edges of structural members, comprising rigid strips and compressible strips arranged in an alternating manner and extending alongside each other and longitudinally inside the gap to form an expansion and sealing assembly having outer sides connected to the edges of the gap, supporting structure means comprising rod-like legs having upper ends connected to said rigid strips, said legs extending and converging downwardly into the gap, said legs having lower ends, and lower means connecting said lower ends of the legs to form springy pairs of legs elastically supporting said assembly in response to the movement of said edges.
Claim 3
Dependent Claim 32 words
The expansion gap sealing device according to claim 1, wherein said springy legs converge downwardly in pairs, whereby the upper ends of a pair of legs are connected to adjacent rigid strips.
Claim 4
Dependent Claim 18 words
The expansion gap sealing device according to claim 1, wherein said legs are inclined relative to the horizontal.
Claim 5
Dependent Claim 23 words
The expansion gap sealing device according to claim 1, wherein said legs are elastically deformable, preferably in a direction transverse to the gap.
Claim 6
Dependent Claim 41 words
The expansion gap sealing device according to claim 1, wherein said means connecting said lower leg ends comprise a bar for each pair of legs, whereby adjacent legs, the lower ends of which are interconnected by said bar, form a pair.
Claim 7
Dependent Claim 36 words
The expansion gap sealing device according to claim 1, wherein said legs are arranged in several rows, and wherein said rows are arranged one behind the other in the direction of the length of the gap.
Claim 8
Dependent Claim 45 words
The expansion gap sealing device according to claim 1, wherein said legs are made of curved wire stock, the upper ends of which are connected to said rigid strips, and the lower ends of which are formed into hairpin bends forming said lower connecting means.
Claim 9
Dependent Claim 26 words
The expansion gap sealing device according to claim 7, wherein said lower connecting means comprise bars and wherein said hairpin bends are connected to said bars.
Claim 10
Dependent Claim 36 words
The expansion gap sealing device according to claim 8, wherein the upper ends of the legs are also formed into hairpin bends which are connected alternately to one and the other of two adjacent rigid strips.
Claim 11
Dependent Claim 34 words
The expansion gap sealing device according to claim 1, wherein said legs are U-shaped or V-shaped members, and wherein the upper ends of the U-shaped or V-shaped members are connected to adjacent rigid strips.
Claim 12
Dependent Claim 35 words
The expansion gap sealing device according to claim 10, wherein the ends of the U-shaped or V-shaped members are displaced relative to each other as viewed in the direction of the length of the gap.
Claim 13
Dependent Claim 50 words
The expansion gap sealing device according to claim 1, wherein the legs are rods with holes through the upper ends, said device further comprising cOnnecting pins extending through said holes of the upper rod ends and through said rigid strips for attaching said upper rod ends to said rigid strips.
Claim 14
Dependent Claim 47 words
The expansion gap sealing device according to claim 1, wherein the rigid strips adjacent to said edges of the structural members are connected to the structural members, whereby the upper ends of said legs connected to said adjacent rigid strips are also connected to the structural members.
