ABSTRACT:
A stopper device for being mountable upon a door knob, and which serves as a bumper for limiting the pivotal travel of the door, thereby preventing a hard door knob bumping against a wall and damaging the same, the stopper device being made of a resilient material, such as either acrylic, plastic or rubber, which absorbs the shock upon impact with the wall, in order to not injure the same, the stopper consisting of a sheath that encloses the door knob.
