Abstract
An extendable key operator which has a handle, an outer extension arm and an inner extension arm pivotally connected to the handle and the outer extension arm. The outer extension arm has a key retaining end portion. The arms are movable between a retracted position in which the arms are positioned adjacent to the handle and an extended position. In the extended position, the key retaining end portion and the arms are extended from the handle to allow a person to operate a key retained on the outer extension arm by grasping the handle. The handle is connected to the outer extension arm by one pulley connected to the handle, another pulley is connected to the outer extension arm and a belt is positioned around the pulleys. The pulleys have slots therein and the belt has complimentary cleats thereon. The cleats are positioned in the slots in the pulleys to synchronize and control the angular movement of the handle and the outer extension arm and lock the angular movement of the outer extension arm with respect to the handle. A locking member is movably mounted on the handle and has a locking projection. The inner extension arm has a first locking depression which receives the locking projection of the locking member when the operator is in the retracted position and a second locking depression which receives the locking projection when the operator is in the extended position. The pulleys, belt, locking member and locking depressions, lock the arms and the handle into a compact, rigid structure in the retracted position and an elongated, rigid structure in the extended position. In the extended position, the key may be used a distance from the hand of the person using the key operator.
