This heavy-duty, sliding panel door guard/bumper includes a rigid base plate which is suitable for mounting upon a doorjamb or a sliding panel in a distortion-free connection, by means of plural fastening anchors. The panel serves as a mount for opposed trunnions which mount a wheel axle thereon. The gudgeons of the trunnions are elevated vertically from the base plate, adjacent one end thereof and the elevation of each trunnion is inclined forwardly to form a sliding slope which corresponds at its proximal end to the circumference of an aligned sliding panel bumper wheel, although the maximum elevation of the trunnions is less than the protruding circumference of the bumper wheel. The wheel has axle bearings therein such that a minimum of friction is presented to passing contact of one heavy duty panel which is slid relative to another. Guard/bumpers are incorporated in large and small sizes when adapted to door panels which are slided relative to each other, the small sizes being positioned for ease of by-pass movement of panels, relative to each other. The door guard/bumper may be variously mounted upon a doorjamb, or upon one of sliding panels which is opposite another. Complementary plural guards may thus be mounted. |
