Door locking handle assembly with built-in combination lock

Abstract

In the handle assembly, a combination lock ( ) is opened by turning each dial discs ( ) a given number of times to establish a combination of marks on the discs, and is incorporated in a handle ( ) and disposed adjacent to a cylinder lock ( ) in the handle. A receiver lever ( ) pivoted on a base body ( ), is controlled by a lock plate ( ). A stopping plate ( ), interlocked with a rotor ( ) of the cylinder lock ( ), engages receiver lever ( ) pivoted to the base body ( ), so that the handle ( ) is held in its folded position. When the combination lock ( ) is in its unlocked condition and the handle ( ) is pulled, the receiver lever ( ) is swung upward by the stopping plate ( ) to release handle ( ) from the base body ( ). A plurality of slots ( ) are formed on a bottom surface of a dent portion ( ) of the handle ( ). An outer peripheral portion of each of the dial discs ( ) projects into the dent portion ( ) through the slot ( ) so that an outer peripheral surface of the dial disc ( ) is set back from a virtual extension plate of the front surface ( ) of the handle ( ). The handle assembly is attached to a door ( ) front side having an opening ( ) into which the base body ( ) is fitted and retained by a pivoted fastening stopper ( ) actuated by set screw ( ) fixing arrangement.
