ABSTRACT:
A door assembly is provided for use in proximity to door openings wherein there is a large amount of material handling vehicle traffic. The assembly includes a frame mounted within the door opening and having upright elongate side sections. Each section has an interior guideway with an elongate entry thereto. Within each section is a pair of guide members forming therebetween a gap aligned with the entry. A flexible door member is slidably mounted on the frame. Opposite marginal side segments of the door member extend through the entries and gaps into the section guideways. Each marginal segment is provided with a plurality of relatively spaced, vertically aligned follower elements normally impassable with respect to the gap. Upon an external force of at least a predetermined magnitude being exerted on an exposed surface of the door member while in a closed mode, the follower elements will exert a predetermined wedging force on the gap-forming portions of the guide members causing a change in the relative dimensions of the gaps and follower elements allowing the follower elements to pass through the gaps and effect at least partial disassembly of the door member from the frame. Each section is provided with an adjustable panel which may be selectively adjusted to an open position exposing the guideway thereby permitting the follower elements to be reassembled in the respective guideway.
