Abstract: A trolley castor having two flanges which freely rotate about a spindle carried by arms of a yoke is described. The flanges are separated by a distance corresponding to the usually standardized distance between the grooves of a walkway surface. Between the flanges is a brake disk which can rotate around the spindle. Fixed to an edge of the brake disk is a brake skid having a sole.

Abstract: The parking brake can be fitted to the wheelchair frame largely regardless of the nominal position of the brake element, and conversely the position of the brake element can be exactly matched to the position of the rear wheel. A two-piece clamp connects a cylindrical bearer to a part of the wheelchair frame and allows the bearer's rotation and lengthwise displacement relative to the frame. One end of the bearer holds the pivoting brake element and locking lever. One arm of the locking lever acts together with the brake element and has two recesses. When the locking lever is moved to a released position, spring action forces the brake element to engage one of the recesses and to be located beside the rear wheel approximately perpendicular to the wheel's rotational axis. When the locking lever is moved to a braking position, the brake element engages the second recess and is located more or less parallel to the rotational axis of the rear wheel.

Abstract: A wheelchair brake includes a pressing lever having a free end which pivots bout a first axis to make braking contact with a wheelchair wheel. The pressing lever is normally urged into a neutral position away from the wheel by an elastic, spring-like member, such as a rubber band or O-ring. A first brake lever for operating the brake by a companion is connected via a Bowden wire to the free end of the pressing lever, so that depression of the first brake lever causes the pressing lever to pivot into braking contact with the wheel. A manually releasable safety catch automatically engages the first braking lever when the lever is depressed, thereby locking the lever in its braking position. A second brake lever is also provided for use by the wheelchair user. The second lever pivots about a second axis causing a pressure part to bear against the same pressing lever causing a braking contact with the wheel. Further pivoting of the second lever also causes the mechanism to lock in a braking position.
