Abstract: Although a door locking handle assembly is small as a whole in thickness in construction, it permits, through its computerized personal management system, a large number of persons or users to have easily and quickly access to their instruments contained in a box provided with the door locking handle assembly. In this assembly, a combination lock (19), which is opened by turning each of a set of its specially marked dial discs (22) a given number of times to establish a unique combination of marks of the dial discs (22), is incorporated in a door handle (13) or in a base body (1). In operation, a locking member (24) of the assembly prevents the door handle (13) from being pulled out of the base body (1), and is driven to reach its unlocked position when the combination lock (19) is opened.
