A sliding bearing for telescopic tubes includes a polymeric disk-shaped body having a central opening and a plurality of spaced outwardly extending shoes, a flexible web coupling adjacent shoes, and apertures for receiving fasteners for attaching the bearing to an inner tube. The shoes have opposed edges that contact ribs on an inner surface of an outer tube. A fixed bearing for telescopic tubes includes a plurality of arcuate segments having ends that overlap with ends of adjacent segments, with the segments including axially extending walls that are radially inwardly inclined. An aperture is formed in the overlapping ends of the segments, such that they can be fastened to an end of an outer tube with fasteners to allow the segments to be adjusted to permit a n inner tube to extend through the bearing.

Abstract

A fluid strut includes a frangible locking member including a generally cylindrical locking pin mounted to an outer cylindrical housing of the strut and extending radially inwardly toward a gas spring cylinder. The locking pin is movable between operative and inoperative positions. In the operative position, the spring-loaded frangible locking pin extends into engagement with the gas cylinder and can advance radially to a locking position once the outer housing extends beyond the location of the gas cylinder. In an inoperative position, the locking pin is held in a retracted position. The end of the locking pin has a reduced diameter, such that, if a purposeful force is placed upon the strut when in a locked position, the pin can shear, allowing the rod to be retracted within the cylinder and the closure member to be closed without damage.

Abstract

A hydraulic drive system readily adapted for either manual actuation or motor-driven actuation due to the unique design of the hydraulic drive and its coupling to either a hand crank or to a motorized drive to provide hydraulic pressure to lift cylinders that can be attached to table legs for vertical adjustment. The hydraulic drive includes a screw jack having an end extending from one end of a housing and splined or otherwise keyed. A manual crank arm or motorized drive assembly includes a coupling which mates with the end of the screw jack to provide a drive force for the hydraulic cylinder drive. The motorized drive assembly includes a pair of toothed hubs and an intermediate flexible sleeve allowing alignment of the motorized drive to the drive assembly as well as providing sound dampening, a cushioned coupling, and facilitates overcurrent detection.
