Abstract
A U-shaped frame has opposite pivoted jaws adapted to move to and from a position closing the frame gap. A releasable locking member is pivoted to the frame in half-bearings, and is held in place by a cover plate that similarly retains the journals of an actuator plate responsible for closing the jaws around an entered wheel. The locking member is rotated out of locking position by forces on a handle that cause the chair to be pushed out of the retainer coupling. Placement of the locking member in the release position causes warning projections to appear above the housing, and these retract into the housing when the unit is in locked condition.
