Mechanical-adhesion glazing
First Claim
1. A glass unit comprising:
- a glass light having an inner surface;
an elastomeric, elongate gasket extending along edges of said glass light and located adjacent said inner surface;
a thin adhesive layer bonding said glass light to said gasket and located between said glass light and said gasket; and
an elongate supporting frame of rigid material extending along the same edges of said glass light and located on the side of said gasket opposite said glass light, said frame including integral flanges which extend into and are essentially non-removably, structurally united with the body of said elastomeric gasket for mechanically fastening said gasket to said frame;
said gasket being of sufficient flexibility to accommodate relative movement between said glass light and said frame, thereby reducing stresses to said adhesive layer.

Abstract
An architectural glass unit comprises a glass light having an inner surface and a flexible structural gasket extending along edges of the glass light and located adjacent the inner surface. A thin adhesive layer bonds the glass light firmly to the structural gasket. A supporting frame extends along the same edges of the glass light and is located on the side of the gasket opposite the glass light. This frame includes means for mechanically fastening the structural gasket to the frame. In one embodiment, a bonding material such as structural silicone directly bonds the glass light to the supporting frame and is arranged along one side of the gasket. L-shaped flanges integrally formed on the frame and rolled into sealing engagement with the gasket are used for the mechanical fastening.

14. Apparatus for securing a glass light to a support member adjacent an edge area of the glass light comprising:
-
a glass light having an edge area; an elongate sub-frame element extending along and in spaced parallel relationship with said edge area; an elongate, high-strength, elastomeric gasket disposed between said sub-frame element and said edge area; said gasket and said sub-frame being mechanically structurally joined by sub-frame flange elements which extned into and are essentially nonremovably joined with the body of said gasket; means adhesively bonding the gasket to said edge area; and means for removably securing the sub-frame to said support member whereby the gasket absorbs movments between the glass light and sub-frame element thereby reducing stresses to without the adhesvie bond between the gasket and glass light edge area. - View Dependent Claims (17, 22)

16. A panel unit for use on a building exterior comprising:
-
a glass panel member having an inner surface; a flexible structural gasket of elastomeric material extending along edges of said panel member and located adjacent said inner surface; a thin adhesive layer bonding said panel member firmly to said structural gasket; and a supporting frame of rigid material extending along the same edges of said panel member and located on the side of said structural gasket opposite said panel member whereby the panel member has a flush exterior, said frame including means for mechanically uniting said gasket with said frame; said gasket being of sufficient size and elasticity as to accommodate relative movement in all directions between the panel and frame thereby reducing stresses jto the adhesive layer. - View Dependent Claims (18, 19)

20. A glass unit comprising:
-
glass light means having an inner surface; a flexible structural gasket extending along edges of said glass light means and located adjacnet said inner surface; said structural gasket having a longitudinally extending recess along one side thereof adapted to receive part of a supporting frame member, said one side of such gasket being adjacent a respective edge of said glass light means and extending perpendicular to said inner surface; said structural gasket further having a longitudinally extending groove along another side thereof; a thin adhesive layer bonding said glass light means firmly to said gasket; and elongate locking strip means having a length corresponding to that of said groove and a cross section sized and shaped to permit said strip means to fit snugly in said groove and to thereby firmly attach said structural gasket to said supporting frame member, wherein said groove has a cross-sectional shaped formed to retain said locking strip means in said groove after said strip means is inserted therein.
