Abstract: An overhead door having two tracks each of which is designed to be mounted on the side of an opening in a building. Each track has a script-v shape in cross-section, and a groove or channel that runs along its longitudinal axis. One or more panels are positioned between the tracks and coupled to each other. Each panel has a multiple-layer design that provides superior insulation. At least two plungers are positioned on each panel and each plunger has a first end which is biased in a first position. In the first position, the first end of the plunger rides within the channel of the track. The plungers are designed with a low-friction tip that wears away after repeatedly traveling in the channel of the track. The plungers may be designed to release from the track when the panel on which they are mounted is impacted, to rotate in whole or in part as they travel in a channel of a track, or both.

Through this open recess, the bearing pin can be reached manually or by means of a tool in order to withdraw it from the bearing bore.

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.
