Abstract
Abstract An insulated glass panel has a frame and spacer structure which prevents foreign matter and moisture from entering between spaced panes while affording low-cost manufacture and repair. The spacer has a pair of opposed recesses mounting beads of resiliently deformable cured elastomeric material, and the beads are compressed against the spacer by the frame which surrounds the periphery of the panes. In certain embodiments, the frame comprises a pair of frame members disposed side by side to form a hollow cavity around the periphery of the panes and snap fasteners releasably connecting the frame members together. The cavity is filled with a foam plastic material which surrounds reinforcing elements located at the corners of the frame to rigidify the frame. In one embodiment, the frame members are hinged together to permit them to pivot relative to one another between open and closed positions about an axis parallel to the edges of the panes to afford installation and replacement of the panes. In another embodiment, the frame is molded around the edges of the panes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
192 words
An insulated panel structure comprising: a pair of panels juxtaposed to define an air gap therebetween, a spacer disposed in said gap between inner peripheral margins of said panels, said spacer having at least a pair of opposed recesses confronting said inner margins of said panels, a resiliently deformable gasket disposed in each of said recesses and having a portion extending outwardly thereof to engage said inner margins, and frame means surrounding said panels and engaging outer peripheral margins of said panels for urging said panels toward one another to compress said gasket thereagainst, said frame means including a first frame member disposed on one side of said pair of panels and a second frame member disposed on the other side thereof, one of said frame members having an inner web portion extending along the peripheral edges of said panels, an outer web on said one member spaced from said inner web, said inner and outer webs spacing said frame members apart to define therebetween a cavity, a foam material contained in said cavity, and means providing complementary mating snap fasteners releasably fastening said inner web to the other of said members.
Claim 2
Dependent Claim
192 words
An insulated panel structure comprising: a pair of panels juxtaposed to define an air gap therebetween, a spacer disposed in said gap between inner peripheral margins of said panels, said spacer having at least a pair of opposed recesses confronting said inner margins of said panels, a resiliently deformable gasket disposed in each of said recesses and having a portion extending outwardly thereof to engage said inner margins, and frame means surrounding said panels and engaging outer peripheral margins of said panels for urging said panels toward one another to compress said gasket thereagainst, said frame means including a first frame member disposed on one side of said pair of panels and a second frame member disposed on the other side thereof, one of said frame members having an inner web portion extending along the peripheral edges of said panels, an outer web on said one member spaced from said inner web, said inner and outer webs spacing said frame members apart to define therebetween a cavity, a foam material contained in said cavity, and means providing complementary mating snap fasteners releasably fastening said inner web to the other of said members.
Claim 3
Dependent Claim
45 words

Claim 4
Dependent Claim
42 words
An insulated panel structure according to claim 1 including hinge means on said outer web for connecting said first and second frame members to permit the same to pivot relative to one another about axes parallel with the edges of the panels.
Claim 5
Dependent Claim
149 words
An insulated panel structure comprising: a pair of panels juxtaposed to define an air gap therebetween, spacer means interposed between inner peripheral margins of said panels to space said panels apart, frame means surrounding peripheral edges of said panels, said frame means including first and second frame members disposed alongside outer peripheral margins of said panels, means providing a hinged connection between said frame members to permit said frame members to pivot about axes parallel to said peripheral edges, and means located intermediate said hinge means and the edges of said panels for releasably fastening said frame members together, said releasable fastening means including means separating said frame members to define a cavity therebetween, one of said frame members having a tongue with an enlarged end portion extending into said cavity, and a filler material contained in said cavity and surrounding said tongue to releasably embed said tongue therein.
Claim 6
Dependent Claim
149 words
An insulated panel structure comprising: a pair of panels juxtaposed to define an air gap therebetween, spacer means interposed between inner peripheral margins of said panels to space said panels apart, frame means surrounding peripheral edges of said panels, said frame means including first and second frame members disposed alongside outer peripheral margins of said panels, means providing a hinged connection between said frame members to permit said frame members to pivot about axes parallel to said peripheral edges, and means located intermediate said hinge means and the edges of said panels for releasably fastening said frame members together, said releasable fastening means including means separating said frame members to define a cavity therebetween, one of said frame members having a tongue with an enlarged end portion extending into said cavity, and a filler material contained in said cavity and surrounding said tongue to releasably embed said tongue therein.
Claim 7
Dependent Claim
33 words
An insulated panel structure according to claim 4 wherein said frame members have laterally-inturned portions engaging said panel margins, and including sealing means disposed between said inturned portions and said inner web means.
Claim 8
Dependent Claim
42 words
An insulated panel structure according to claim 4 including inner web means disposed between said frame members adjacent the peripheral edges of said panels, said releasable fastening means including complementary mating elements on said inner web mens and said other frame member.
Claim 9
Dependent Claim
