Abstract: An improved laterally resilient and displaceable mechanical door bumper for moving an elongated retractable shaft. The body or mold of the door bumper includes a base portion in which mounting screws are firmly anchored into the wood of the adjacent door portion. The door bumper shaft includes a rubber end piece that is glued and snapped onto the end of the door bumper shaft for cushioning the impact of the door bumper against a wall. The side of the door bumper receives rollers which are attached to the side portion of the mold and can be compressed during impact. The rollers are adapted to contact a door frame, which forces the door bumper shaft to retract. The door bumper is devoid of separable parts or sharp edges that might injure persons, particularly children, who come in contact with the door bumper.
