Abstract: To avoid repeated damage to a lower section of a metal roll-up door, the lower section is replaced by a more impactable curtain assembly. The curtain assembly is so readily scalable, horizontally and vertically, that much of it can be manufactured and field assembled right at the installation site. The curtain assembly may comprise one or more strips of fabric that are cut from a roll of a certain width. The length of the fabric strips corresponds to the width of the doorway, and the number of strips is based on the vertical span of the door section that is being replaced. Windbars can be attached where adjacent strips connect to each other. A weighted, semi-rigid bottom bar reinforces the lower edge of the finished roll-up curtain. Under impact, the bottom bar has sufficient flexibility to allow the curtain to resiliently break away from within the door's vertical guide tracks.

Abstract: A positional control device is provided to prevent accidental drifting of an overhead sectional door upward or downward from a fully opened, partly opened or fully closed position. The device allows the door to be manually moved to a different elevation without requiring a separate operation to release the door from its original position. This is achieved by a mechanism which couples the upward and downward motion of the door to the rotation of a sprocket wheel engaged with a spring loaded ratchet arm with a bifurcated head specially shaped for ratcheting engagement with the teeth of the sprocket wheel. Suitable adjustment of the spring allows the ratchet mechanism to hold the door in its given position by exerting a force which can readily be overcome by manual raising or lowering the door to a different position.
