Abstract

A process for making a panel having a supported member formed either of a simple or multiple glass window and a supporting part formed of preformed parts received on and at spaced locations around the glass window for supporting a light frame thereby to accommodate the panel for use as a window or door.

Claims

1. A process of making a panel comprising

(a) a positioning plural spaced members along an edge of a glass sheet,

(b) introducing an elastic adhesive between said members and said sheet and allowing said adhesive to set to bond said members to said sheet,

(c) disposing a frame of channel outline around said members;

(d) inserting a strip of a preformed joint material between at least one side of said members and said frame, and

(e) attaching said frame to said members with mechanical fasteners.

2. The process as recited in claim 1 wherein the elastic adhesive is of a polysulfide type glue.

3. The process as recited in claim 1 wherein the elastic adhesive is injected under pressure through a hole provided along the axis of symmetry of each spaced member.

4. The process as recited in claim 1, 2 or 3 wherein

(a) said plural spaced members are positioned along an edge of at least one glass sheet, and

(b) said spaced members each including

(1) a base portion having a pair of wing portions extending from an edge normal thereto, and each said spaced member disposed at spaced locations around said glass sheet with said base portion located in opposed relation to the edge of said glass sheet and each said wing portion placed in projection to and slightly spaced from and disposed exteriorly of a respective outside face of said glass sheet,

(2) attachment means carried by each said base adapted for removable attachment of said frame,

(3) securing means comprising an adhesive layer disposed over an area substantially equal to the area of each said wing portion of said spaced member.

5. The process as recited in claim 4 wherein each said spaced member is formed of a spring steel having a thickness less than about 1 mm.

6. The process as recited in claim 4 wherein the elastic adhesive is disposed in a layer having a thickness of at least about 0.5 mm.

7. The process as recited in claim 4 wherein each said base of each said spaced member includes

(a) an opening adapted to receive an elastic adhesive injection nozzle means,

(b) a pair of ribs substantially equidistantly spaced from said opening, said ribs providing a bearing surface to space each said spaced member from said side of said glass sheet and serving to guide said elastic adhesive into the space between each said wing and said side, and

(c) a boss disposed outwardly of each rib, said attachment means being carried by said bosses.

8. The process as recited in claim 4 further including means for assisting in the distribution of stress between said frame and each said spaced member, said distribution means formed of a material which is less rigid than that either of said frame and each said spaced member, and said distribution means being secured between said frame and each said rider.

9. The process as recited in claim 8 further including cushion frame means, and wherein said frame is of L-shaped outline to extend along a face of said glass sheet, a mastic material disposed between said frame and said bracket face and means of said distribution means for supporting said cushion frame means and disposition against the other face of said supported member.

10. The process as recited in claim 8 further including a pair of cushion frame means, and wherein said frame is in the form of a plate, and means on said distribution means for supporting said cushion frame means in disposition against each side of said glass sheet.

11. The process as recited in claim 4 wherein at least one of said wings of each said spaced member is provided with at least one opening therethrough, each said opening in each wing further comprising socket means, said socket means equal in number to the number of openings in said wings received in and close to the respective openings and to bear on a face of said glass sheet with which said wing is in projection, each socket having a central bore within a wall adapted to retain a charge of glue forming a stud which contacts and adheres to said face.

12. The process as recited in claim 11 wherein each said opening in each wing and wall of each said socket have complementary interacting means whereby each said socket is captive in a respective opening.

13. The process as recited in claim 11 wherein each of said wings of each said spaced member is provided with a circular opening therethrough, said openings being locked on a common axis perpendicular to the axis of symmetry of said spaced member.

14. The process as recited in claims 11, 12 or 13 wherein after the curing of the elastic adhesive:

(a) hard glue is introduced into the sockets, and

(b) the hard glue is allowed to set into studs adhering to the glass.
