Abstract

A glazing consisting of two panes located opposite one another and retained by a rigid frame provided with leakproofing means and consisting of sections which bear on the inner faces of the panes and which are fastened to these by means of an anchor preventing the panes from moving apart, this frame being provided with at least one deformable and leakproof member for equalizing pressure between the outside and inside of the glazing, this member being independent of the said leakproofing means and being located on the inside of the glazing in relation to the said sections, and the said sections having, towards the outside of the glazing, a shape which allows direct attachment of accessories enabling the glazing to interact with a fixed surround.

This glazing provides a considerable increase in the internal volume and therefore the possibilities of heat and sound insulation, as a result of the fitting of interpolated elements. Furthermore, it can be produced completely at the factory, ready to be installed in its surround.

Claims

1. A glazing comprising two panes located opposite one another and retained by a rigid frame provided with leakproofing means, said frame having sections which are contained completely in the gap defined by the planes of the outer faces of the panes, which sections bear on inner faces of the panes and which sections are fastened to the panes by an anchor preventing the panes from moving apart, said sections having wings and a shape toward the outside of the glazing which allows direct attachment of accessories so as to enable the glazing to interact with a fixed surround, said frame being provided with at least one deformable and leakproof member for equalizing pressure between the outside and inside of the glazing, said member being independent of said leakproofing means and being located on the inside of the glazing in relation to said sections, said frame being also provided with at least one auxiliary member being supported by said wings with projections of one of said auxiliary member and said sections penetrating into grooves of the other of said auxiliary member and said sections with clearance, said auxiliary member dividing the inner space of the glazing into two communicating chambers which are subjected to the same pressure, one of said chambers being peripheral and containing said pressure-equalizing member, said auxiliary member being so made and shaped as to enable said pressure-equalizing member to be wholly protected against the radiation penetrating through the panes, said pressure equalizing member being a pocket in the form of a bellows.

2. A glazing as claimed in claim 1, wherein the said peripheral chamber contains, in addition to the equalizing member, a dehydrating substance, and leakproof means for renewing said dehydrating substance.

3. A glazing as claimed in claim 2, wherein said glazing includes bearing boxes which extend into said first chamber.

4. A glazing as claimed in claim 1, wherein glazing includes bearing boxes which extend into said first chamber.

5. The glazing according to claim 1, wherein said auxiliary member is provided with means for supporting at least one additional device located inside the glazing.

6. A process for producing a glazing comprising the steps of:

providing frame sections with a pressure-equalizing member in the form of a bellows;

bonding the sections to one another and to two opposing panes to form a leakproof assembly;

partitioning space enclosed by said panes and said frame into a first, peripheral chamber and a second chamber in communication with said first chamber by placing an auxiliary member between said sections with projections of one of said auxiliary member and said sections fitting grooves of the other of said auxiliary member and said sections with clearance;

locating said pressure-equalizing member within said peripheral chamber so as to wholly protect the pressure-equalizing member against radiation penetrating said panes;

after bonding, producing a pressure difference between the two faces of the equalizing member through a sealable orifice in one section and communicating with an interior of the glazing, this pressure difference being such that the average shape of said equalizing member during use will be intermediate between its extreme shapes and subsequently sealing off communications between the interior of the glazing and the outside at least up to the moment when the glazing is used.

7. A glazing comprising:

a pair of spaced apart panes;

a frame peripherally anchoring said panes, said frame including opposing sections which bear on inner faces of said panes, said frame including also an auxiliary member supported by said sections with projections of one of said auxiliary member and said sections fitting into grooves of the other of said auxiliary member and said sections with clearance, said auxiliary member partitioning space inside said glazing into a first, peripheral chamber situated between said opposing section members and a second chamber, said first and second chambers communicating with each other through said clearance;

a pressure-equalizing bellows located in said peripheral chamber, whereby said sections and said auxiliary member protect all of said bellows from radiation penetrating the panes;

passage means through said frame for communicating said bellows with an environment outside the glazing; and

leakproofing gasket means for forming a water vapor barrier between said frame and said panes.

8. The glazing as claimed in claim 7, wherein said frame is within planes defined by outer faces of said panes.

9. The glazing as claimed in claim 7, wherein said frame has a shape toward the outside of the glazing which allows direct attachment of accessories so as to enable the glazing to interact with a fixed surround.

10. The glazing as claimed in claim 7, wherein said auxiliary member includes means for supporting devices inside the glazing.

11. A method of equalizing pressure within a glazing comprising spaced apart panes, said method comprising the steps of:

supporting peripheries of the panes with a frame having a generally U-shaped cross-sectional form, opposing sections of said frame being placed adjacent inner faces of the panes;

bonding said sections to said panes to form a leak-proof assembly;

partitioning space enclosed by said panes and said frame into a first, peripheral chamber and a second chamber in communication with said first chamber by supporting an auxiliary member between said sections with clearance;

locating a pressure-equalizing bellows in said first chamber so as to protect all of said bellows against-radiation entering the glazing through said panes; and

communicating said bellows with an environment outside said frame through said frame.
