Abstract

A frameless truck cap lift door is disclosed having a concealed hinge structure and including a transparent window portion of generally uniform thickness having six holes, two of which extend along an upper edge thereof. There is a relatively rigid support bar having at least a pair of holes which are simutaneously alignable with the window holes. A pair of hinges are adapted to be fastened near an upper edge of the truck cap each hinge having a pivotable arm extending from the truck cap and terminating in an apertured flange. The spacing between the flanges when the hinges are fastened to the truck cap is substantially the same of the spacing between the holes in the support bar and the holes in the window whereby a pair of threaded fasteners may be passed each through the window, the support bar and one flange for securing the window pivotably to the cap. This eliminates any need for a window frame whereby facilitating use of any of a wide variety of window shapes while allowing the use of relatively thin glass for the window.

Claims

1. A frameless truck cap lift door having a concealed hinge structure comprising:

a transparent window portion of generally uniform thickness having at least a pair of holes along an upper edge thereof;

a relatively rigid support bar having at least a pair of holes simultaneously alignable with the window holes;

a pair of hinges adapted to be fastened near an upper edge of the truck cap, each hinge having a pivotable arm extending from a truck cap and terminating in an apertured flange, the spacing between the flanges when the hinges are fastened to a truck cap being substantially the same as the spacing between the holes in the support bar and the holes in the window whereby a pair of threaded fasteners may be passed each through the window, the support bar and a corresponding apertured for securing the window pivotably to the cap.

2. The frameless truck cap lift door of claim 1 further comprising a pair of rotatable door latches and a pair of braces and wherein said pair of holes are near, but spaced from the upper periphery of the window, there being six holes through the window, two for said threaded fasteners, two for rotatable door latches, and two for braces to hold the window in its open position.

3. The frameless truck cap lift door of claim 2 further comprising an interior frame portion to which the hinges are fastened, and a seal fixed to the interior frame portion and adapted to engage the inner surface of the window along the top between the pair of holes and the upper periphery.

4. The frameless truck cap lift door of claim 3 wherein each of the pivotable arms is arcuate in shape so as to allow ample space to accommodate the inner frame portion and seal when the window is swung out.
