Abstract
There is disclosed a releasable door stop assembly for a bidirectionally swinging door including a retractable stop member which normally permits opening of the door in one direction, thus acting as a stop against opening of said door in the opposite direction. The stop member is free floating and is spring biased, such that it can be retracted manually to permit opening of the door in the opposite direction. The biasing of the free floating stop member is effected by use of a leaf spring which localizes the applied force limiting same generally to the forward portions of the stop member. As such, upon manual depression, the rearward portion of the free floating stop member moves inwardly easily until a segment thereof bottoms, with the forward portion of said stop member then being rocked forward to retract the stop member entirely. The rocking movement serving to dispose an outer surface portion of the stop member at a level which precludes pinching of the operator's finger as the door passes the stop member. In addition, there is included a set screw adjustment means, whereby the initial position of the leaf spring may be varied, to accommodate tolerance variations in the spring shape.
