ABSTRACT:
A support device pivotally supports a resilient body on the leading surface of either a door or a sliding door frame in a manner whereby the gravitational force on the body moves the body between a sliding door and the frame. The body is mounted on a rod which is accommodated in a mounting housing. The body is manually movable away from the door and the frame, so that the body is positioned by gravitational force in abutment with the leading surface of the door when the door is closed. This permits the door to be securely closed with its leading edge in abutment with the frame. The body is interposed by gravitational force between the leading edge of the door and the frame when the door is open thereby preventing the door from closing fully by preventing the leading edge of the door from abutting the frame and thus protecting hands from being crushed between the door and the frame. A deactivation preventing device in the housing limits the extent of manual movement of the ball away from the leading edges of the door and the frame to prevent positioning of the ball at a point from which the gravitational force on the ball moves the ball toward the leading surface of the door or the frame rather than between the door and the frame.
