Abstract:
1. A window or door frame for placement in an opening to be filled in a wail comprising: a first frame member for placement in the opening; a second frame member for placement in the opening; each of the first and second frame members having an inner surface for facing generally at right angles to a plane of the wall inwardly of the opening, an outer surface for facing generally at right angles to the plane of the wall and opposite to the inner surface, a first side surface for facing generally in a direction co-planar with the wall toward a window or door to be supported thereby and a second side surface for facing generally in a direction co-planar with the wall opposite to the front surface; the first and second frame members being arranged outer surface to outer surface to form a mullion across the opening with the first side surfaces thereof generally coplanar and the second side surfaces thereof generally coplanar; the outer surface of the first frame member having first and second recesses therein extending longitudinally of the first frame member with the first recess arranged adjacent the first side surface and the second recess arranged adjacent the second side surface; the outer surface of the second frame member having first and second recesses therein extending longitudinally of the second frame member with the first recess arranged adjacent the first side surface and the second recess arranged adjacent the second side surface; the first recess of the first frame member being aligned with the first recess of the second frame member and the second recess of the first frame member being aligned with the second recess of the second frame member; each of the recesses having a mouth at the outer surface which is narrower than a portion of the recess spaced from the outer surface; a first connecting member arranged to lie along the aligned first recesses with a portion of the first connecting member within the first recess of the first frame member and a portion of the first connecting member within the first recess of the second frame member; the portions of the first connecting member being arranged to be wider than the respective mouth of the first recesses such that the first connecting member prevents the first and second frame members from being pulled apart; the portions of the first connecting member being arranged to be shallower than the respective first recess so that the first connecting member is a loose fit in the first recesses when the first and second frame members are directly outer surface to outer surface; a second connecting member arranged to lie along the aligned second recesses with a portion of the second connecting member within the second recess of the first frame member and a portion of the second connecting member within the second recess of the second frame member; the portions of the second connecting member being arranged to be wider than the respective mouth of the second recesses such that the second connecting member prevents the first and second frame members from being pulled apart; the portions of the second connecting member being arranged to be shallower than the respective second recess so that the second connecting member is a loose fit in the second recesses when the first and second frame members are directly outer surface to outer surface; a first insert member for engagement with the first and second frame members on the first side surfaces thereof at a location thereon at the outer surfaces thereof; the first insert member having an insert portion for insertion between the outer surfaces of the first and second frame members adjacent the first recesses thereof so as to force the outer surfaces apart and so as to pull the mouths of the first recesses into tight engagement with the respective portions of the first connecting member; the first insert member having a cover portion covering a junction between the first side surfaces of the first and second frame members; a second insert member for engagement with the first and second frame members on the second side surfaces thereof at a location thereon at the outer surfaces thereof; the second insert member having an insert portion for insertion between the outer surfaces of the first and second frame members adjacent the second recesses thereof so as to force the outer surfaces apart and so as to pull the mouths of the second recesses into tight engagement with the respective portions of the second connecting member; and the second insert member having a cover portion covering a junction between the second side surfaces of the first and second frame members.
