Abstract
In the handle assembly, a combination lock (6) is disposed adjacent to a cylinder lock (13) in the handle (2). A locking plate (11) is interlocked with a rotor (8) of the lock (13), and it engages with a shoulder (15) of a receiver lever (16), which is a intermediate actuating member, so that the door handle (2) is held in its folded position. When the combination lock (6) is held in its unlocked condition and the handle (2) is pulled, the receiver lever (16) is swung upward by the locking plate (11) to release the handle (2) from the body (1). Each of the predetermined mark of each of the marked dial discs (4) for unlocking is detected by turning each of the marked dial discs (4) until the resetting member (72) is brought into engagement with each of the detecting grooves (71).
