Abstract

A window frame comprises first and second window pane mounting frame pieces generated from a single extrusion with a bridge between the two frame pieces. The frame pieces are separated from one another at the bridge producing a bridge part on each of the frame pieces. The first frame piece has a side recess aligned with its bridge part to receive a fastener for mechanically securing the frame pieces back together with one another from opposite sides of the window pane through the bridge parts of the respective frame pieces.

Claims

1. A window frame comprising first and second frame pieces having first and second bridge parts generated from a single extrusion and then separated from one another between said bridge parts and said first frame piece having a side recess aligned with said first bridge part to receive a fastener for mechanically securing said frame pieces to one another from opposite sides of a window pane through said bridge parts and said bridge parts having male and female end surfaces which fit with one another in forming said window frame.

2. A window frame as claimed in claim 1, wherein said male end surface has a tapered configuration providing a guide into said female end surface when said bridge parts are mechanically secured to one another.

3. A window frame as claimed in claim 1 wherein said side recess extends at least substantially full length of said first frame piece and includes an elongated snap cover over said recess.

4. A window frame comprising first and second frame pieces having first and second bridge parts generated from a single extrusion and then separated from one another between said bridge parts and said first frame piece having a side recess aligned with said first bridge part to receive a fastener for mechanically securing said frame pieces to one another from opposite sides of a window pane through said bridge parts and wherein said second bridge part has a generally hollow construction provided with internal ribs for engaging the fastener.

5. A window frame as claimed in claim 4, wherein one of said ribs faces outwardly of and spans said second bridge part and includes a central recess providing a fastener guide into said second bridge part.
