Abstract
Abstract An opening of the type comprising at least one sliding leaf, in particular a panel of transparent or translucent material such as window-glass, plate-glass, or plastic material. The sliding leaf has at least one flange which is oriented at an oblique angle with respect to the plane of the leaf in the closed position. The flange is applied against a bearing surface of the opening which is oriented accordingly, said bearing surface being formed along the length of the flange and over at least part of the width of said flange. The flange which is thus attached to the leaf has a contributory role in ensuring leak-tightness of the closure.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
An opening comprising a frame fitted with two leaves made of glass at least one of which is slidably mounted relative to said frame, each of said leaves having an integral flat vertical flange extending at an oblique angle to the plane of the rest of the leaf, said flanges being of glass, of one piece with their associated leaves, and applied against each other in the closed position.
Claim 2
Dependent Claim
69 words
An opening comprising a frame fitted with two leaves made of glass at least one of which is slidably mounted relative to said frame, each of said leaves having an integral flat vertical flange extending at an oblique angle to the plane of the rest of the leaf, said flanges being of glass, of one piece with their associated leaves, and applied against each other in the closed position.
Claim 3
Dependent Claim
17 words
An opening as claimed in claim 1, wherein each of said flanges is fitted with a seal.
Claim 4
Dependent Claim
17 words
An opening as claimed in claim 2, wherein the seals are spaced apart in the closed position.
Claim 5
Dependent Claim
22 words
An opening as claimed in claim 1, wherein the frame comprises guide means for applying the flanges against each other under pressure.
Claim 6
Dependent Claim
70 words
An opening comprising a frame fitted with two leaves made of glass at least one of which is slidably mounted relative to said frame, each of said leaves having a vertical flange of glass secured thereto by means of a flexible seal, said flanges bearing against each other and extending at an angle not exceeding 90* with respect to the extended plane of the leaves respectively in the closed position.
Claim 7
Dependent Claim
70 words
An opening comprising a frame fitted with two leaves made of glass at least one of which is slidably mounted relative to said frame, each of said leaves having a vertical flange of glass secured thereto by means of a flexible seal, said flanges bearing against each other and extending at an angle not exceeding 90* with respect to the extended plane of the leaves respectively in the closed position.
Claim 8
Dependent Claim
55 words
An opening as claimed in claim 5, wherein the flexible seal is so shaped that the flange is disposed substantially in the plane of the leaf in the rest position and wherein the frame carries means for producing the deflection of said flange in the closed position and the correlative elastic deformation of the seal.
Claim 9
Dependent Claim
25 words
An opening as claimed in claim 5, wherein the flexible seal is provided with a projecting sealing rib which is directed towards the other leaf.
Claim 10
Dependent Claim
33 words
An opening as claimed in claim 5, wherein the flexible seal is so shaped that a dihedral angle is made between the flange and the plane of the leaf in the rest position.
