Abstract: An energy-absorbing bumper system adapted to be mounted on a support structure which may be either a stationary structure or a movable structure, such as a vehicle, includes a deformable hollow longitudinally-extending bumper member, and a piston cylinder assembly adapted to be fixedly mounted on the support structure. The assembly includes a piston head reciprocatively mounted within the chamber of the assembly and is adapted to move toward and away from the structure, a piston rod fixedly connecting the head and the bumper member, and a head retaining device for maintaining releasably the head against the force of a spring which urges resiliently the head toward the bumper member, the head retaining device being adapted to release the head in response to a member-deforming impact on the hollow member. The bumper member includes an elongated gas-tight chamber extending the length of the bumper member and containing a gas under pressure to help absorb impacts.

Abstract: Gravity-actuated self-closing hardware adapted to be attached to a closure, such as a door, for mounting swingably the door to a door frame to enable the door to swing between an open position out of the plane of the door frame and a closed position disposed within the plane of the door frame, includes an upper universal mounting device adapted to mount the top edge of the door at one of the top corner portions thereof to the door frame to support swingably and universally the door from the frame about a point disposed within the plane of the door frame so that the door disposed normally at rest in the closed position can swing out of the plane of the door frame and the lower portion of the door can tilt upwardly, and a lower universal mounting device adapted to mount the side edge of the door near the bottom edge thereof below the upper device to the adjacent portion of the door frame to cause the lower portion of the door to swing about a point outside of the plane of the door frame and to cause the lower p
