SYSTEM FOR STABILIZING THE TOP LAMELLA AGAINST WIND LOAD BY USING A LINEAR CHAIN |
摘要 |
<p>A mechanical link is provided to lessen or eliminate air infiltration between a topmost lamella of a rollup door and the lintel of the doorway. The link is deployed in an unfolded configuration to support the topmost lamella against deflection caused by application of a force perpendicular to the plane of the door. The link components are folded into a storage position upon rolling up of the door upon a series of take-up discs.</p> |
