Abstract

A thermal break frame for supporting a planar object such as a pane of glass is disclosed. The thermal break frame includes a main frame member, a secondary frame member, and a thermal break material which supports the main frame member and secondary frame member in spaced relationship. The thermal break material also thermally insulates the main frame member from the secondary frame member. The planar object is held between the main frame member and the second frame member in a vertical orientation. A load transfer member is provided to support the planar object and this load transfer member is in turn supported by the main frame member so that the main frame member supports substantially all the weight of the planar object.

Claims

1. A thermal break frame for supporting a planar object such as a pane of glass, comprising:

a main frame member including a laterally extending portion and a horizontally extending lip;

a secondary frame member;

a thermal break material which supports in spaced relationship said main frame member and said secondary frame member and which thermally insulates said main frame member from said secondary frame member;

a means for holding the planar object between said main frame member and said secondary frame member in a vertical orientation; and

a load transfer member including a flat horizontal surface, and a laterally and downwardly extending portion having a distal end, said extending portion bearing against said laterally extending portion of said main frame member, and said distal end of said downwardly extending portion being located beneath and bearing against said horizontally extending lip, whereby said load transfer member is supported by said main frame member and in turn supports the weight of the planar object such that the weight of the planar object is borne by said main frame member.

2. A thermal break frame as claimed in claim 1 wherein said thermal break material is polyurethane.

3. A thermal break frame as claimed in claim 2 wherein said main frame member and said secondary frame member are made of extruded aluminum.

4. A thermal break frame as claimed in claim 1 further including an insulating setting block on which the planar object rests, said setting block being in bearing contact with said load transfer member.

5. A thermal break frame as claimed in claim 4 wherein said holding means is an exterior bead and an interior bead, said beads being made of a thermally insulating material such that with said setting blocks and said beads, said planar object is thermally insulated from both said frame members.

6. A thermal break frame as claimed in claim 1 wherein said extending portions of said load transfer member and of said main frame member include mating flat horizontal surfaces.
