ABSTRACT:
Improvements in separable hinge mechanisms. A problem with such mechanisms is that, over a relatively long hinge axis, the hinge pins tend to bind due to misalignment. The invention provides positive alignment and minimizes off-center loads. Mechanism (8) has two opposing integral leaves (10, 20). Each leaf (10, 20) has a plurality of knuckles (12, 30, 32, 32') attached thereto. These form a plurality of axially spaced hinge stations (18). Each station (18) has a corresponding hinge pin (28). Each pin (28) is attached to one of two slide bars (22) that are mounted on leaf (20) for sliding movement parallel to axis (X). Bars (22) are mounted by a center mounting lug (42) and guide rod (46) that carries a spring abutment (26) for each bar (22). Leaves (10, 20) are separated by squeezing toward each other two adjacent finger tabs (24), one on each bar (22). This compresses two springs (48) mounted on rod (46) which bias the bars (22) and pins (28) into a position in which leaves (10, 20) are connected.
