ABSTRACT:
An abutment swivel doorstop has a mounting plate mountable onto a door frame, a stop member pivotally and slidably mounted on the mounting plate, a biasing means for urging the stop member in the disengaged position, a keeper pivotally mounted on the mounting plate, and a latch mountable on a door which is hingedly mounted within the door frame. The stop member is rotatable between a door opening position and a door blocking position and slidable between a disengaged and engaged position. The keeper is rotatable relative to the stop member between a locked and an unlocked condition. The keeper has a cam for urging the stop member against the biasing means and into the engaged condition as the keeper rotates between the locked and unlocked conditions. As the keeper rotates between the locked and unlocked conditions, the stop member engages and disengages the mounting plate and the latch for locking and unlocking the door to the door frame.
