Abstract
Abstract A joint to provide elasticity and moisture permeability. The joint is comprised of alternate layers of elastic open and closed-cell materials. The materials are corrugated, creating recesses in the closed-cell material which are filled with the open-cell elastic material. When the joint is compressed, the pockets of open-cell material remain permeable to moisture, while the joint retains the elasticity of the closed-cell material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A composite joint comprising first and second layers, one of said layers overlying the other of said layers, said layers defining an undulating interface along their area of contact, one of said layers being composed of a cellular material having closed cells, and the other of said layers being composed of a cellular mateRial having open cells, the arrangement of said first and second layers providing areas of alternating thickness of said first and second layers thereby defining, in the compressed state of said joint, a first series of alternating passages permitting the relatively easy passage of fluid therethrough, and a second series of alternating areas of relatively high resistance to compression.
Claim 2
Dependent Claim
112 words
A composite joint comprising first and second layers, one of said layers overlying the other of said layers, said layers defining an undulating interface along their area of contact, one of said layers being composed of a cellular material having closed cells, and the other of said layers being composed of a cellular mateRial having open cells, the arrangement of said first and second layers providing areas of alternating thickness of said first and second layers thereby defining, in the compressed state of said joint, a first series of alternating passages permitting the relatively easy passage of fluid therethrough, and a second series of alternating areas of relatively high resistance to compression.
Claim 3
Dependent Claim
66 words
The composite joint of claim 1, further comprising a third layer of closed-cell material arranged in contact with the surface of said open-cell material layer opposed to the surface of the latter contacting said first-mentioned closed-cell material layer, and defining with said open-cell material layer a second undulating interface defining areas of alternating thickness of said open-cell material layer between said two layers of closed-cell material.
Claim 4
Dependent Claim
117 words
Composite joint according to claim 1, characterized by the fact that it is formed of cellular elastic materials, one of high elastic resistance with closed cells and another of low elastic resistance with open cells, distributed along the entire joint in layers assembled along one or more longitudinal connecting surfaces, the intersection of which with the vertical longitudinal plane is in the general shape of sinusoids so as to provide, in the compressed condition of the joint an alternation of zones of high resistance to compression between which there are arranged zones in which the force of compression exerts less stress permitting a less compressed condition of the open-cell material and therefore easy passages for a fluid.
Claim 5
Dependent Claim
86 words
Composite joint according to claim 1 characterized by the fact that it is composed of cellular elastic materials one with open cells and another with closed cells distributed along the entire joint in layers assembled along one or more longitudinal connecting surfaces, the intersection of which with a vertical longitudinal plane is a broken trapezoidal line so as to provide in the compressed condition of the joint an alternation of zones of high resistance to compression between which there are zones of easy passage for water.
Claim 6
Dependent Claim
18 words
Composite joint according to claim 1 characterized by the fact that the open-cell porous elastic material is polyurethane.
Claim 7
Dependent Claim
18 words
Composite joint according to claim 1 characterized by the fact that the closed-cell elastic material is a polyethylene.
Claim 8
Dependent Claim
18 words
Composite joint according to claim 1 characterized by the fact that the closed-cell elastic material is foam rubber.
