Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
114 words
An element for doors, windows or outside-wall panels which is flat and formed of at least panels (2, 3) which are spaced apart from each other and connected together by a peripheral spacer (4) and forms an inner free chamber therebetween, the inner free chamber (5) being filled with gas, comprising integrated means (7) which make it possible to take up variations in volume of the gas, consisting of an automatically variable volume placed within the inner free chamber, the automatically variable volume being formed, on the one hand, by the peripheral spacer and, on the other hand, by a deformable flexible membrane (9) wherein the membrane forms an integral part of the spacer.
Claim 2
Dependent Claim
114 words
An element for doors, windows or outside-wall panels which is flat and formed of at least panels (2, 3) which are spaced apart from each other and connected together by a peripheral spacer (4) and forms an inner free chamber therebetween, the inner free chamber (5) being filled with gas, comprising integrated means (7) which make it possible to take up variations in volume of the gas, consisting of an automatically variable volume placed within the inner free chamber, the automatically variable volume being formed, on the one hand, by the peripheral spacer and, on the other hand, by a deformable flexible membrane (9) wherein the membrane forms an integral part of the spacer.
Claim 3
Dependent Claim
12 words
An element according to claim 1 wherein the spacer (4) is rigid.
Claim 4
Dependent Claim
33 words
An element according to claim 1 wherein the spacer (4) and the membrane (9) are made of a synthetic material, the membrane (9) having a Shore hardness less than that of the spacer.
Claim 5
Dependent Claim
45 words
An element according to claim 1 wherein, in cross-section, the spacer (4) has the shape substantially of a U formed of a web (12) and two flanges (10, 11), the web (12) being of a thickness greater than a displacement D of the membrane (9).
Claim 6
Dependent Claim
31 words
An element according to claim 4, wherein the web (12) of the U has a cut-out (13) which is pseudo rectangular in cross section, permitting the displacement D of the membrane.
Claim 7
Dependent Claim
25 words
An element according to claims 5 wherein the spacer (4) has inlet and outlet means (14) for the gas, preferably air, in a cut-out (13).
Claim 8
Dependent Claim
29 words
An element according to claim 6, wherein the inlet and outlet means (14) are formed by an orifice (15) which permits communication between the cut-out (13) and the outside.
Claim 9
Dependent Claim
22 words
An element according to claim 7 wherein the orifice 15 is located at the level of the bevel of the spacer (4).
Claim 10
Dependent Claim
42 words
An element according to claim 1 wherein a cover (17) in the shape of a pseudo U is fitted between the flanges (10, 11) of the spacer (4) and that a dehydrating agent (19) is present in a container (18) thus formed.
Claim 11
Dependent Claim
90 words
An element according to claim 1 comprising at least two peripheral spacers (23, 24) placed side by side and each having integrated means (25, 26) which permit the taking up of variations in volume of the gas, at least one foldable blind arranged between the two panels (3,4), a first and a second sealing barrier between the panels and the spacer, the first sealing barrier being formed of a cord (43) of polyisobutylene which is extruded hot and compressed and the second sealing barrier being formed by a silicone gasket.
