Although a door locking handle assembly is small as a whole in thickness, it permits through a computerized personal management system of users a plurality of persons or users to have access to instruments contained in a box provided with the door locking handle assembly in an easy manner. In the assembly, a combination lock (19) opened by turning each of a set of its specially marked dial discs (21) a given number of times to establish a unique combination of marks of the dial discs (21) is incorporated in a door handle (13) or a base body (1) of the assembly. In operation, a locking member (44) 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.
In a door locking handle assembly provided with a base body (1) which is fixedly mounted on a door (2), wherein a door handle (13) is pivoted to said base body (1) so as to be capable of being pulled out and pushed down relative to said base body (1) and also turning on its pivoted end, wherein a lock plate (11) directly or indirectly connected with said door handle (13) is disengaged from a receiving portion (18) of a stationary frame element (17) such as a main body of a box when said door handle (13) is pulled out and turned or turned after its pulling-out operation, the improvement wherein:

1. Field of the Invention
The present invention relates to a door locking handle assembly of a pull-out and side-swinging lever-action type, in which a door handle is pivoted to a base body of the assembly so as to be pulled out and pushed down relative to the base body and turned on its pivoted end.
2. Description of the Related Art
The above and other objects, advantages and features of the present invention will be more apparent from the following description taken in conjunction with the accompanying drawings in which:
FIG. 1 is a front view of an embodiment of the door locking handle assembly according to the first aspect of the present invention;
FIG. 2 is a rear view of the door locking handle assembly shown in FIG. 1;
The best modes for carrying out the present invention will be described in detail using embodiments of the present invention with reference to the accompanying drawings.
A first embodiment of a door locking handle assembly according to the first aspect of the present invention is shown in FIGS. 1 to 13. In this first embodiment, a base body 1 is mounted in a mounting hole 3 of a door 2 from a rear surface of the door 2 in an insertion manner, and firmly fixed to the door 2 through a washer plate 4 (shown in FIG. 4) and a plurality of screws 7 (FIG. 5) in this order by fastening the screws 7 so as to be threadably engaged with a threaded hole 6 of the base body 1. On the other hand, a packing member 8 is inserted into a clearance between a peripheral edge portion of the base body 1 and a front surface of the door 2. Formed in an upper portion of a rear surface of the base body 1 is a bearing sleeve portion 9 extending in a direction perpendicular to the front surface of the base body 1. Rotatably inserted in this bearing sleeve portion 9 of the base body 1 is a locking shaft 10 which is prevented from axially moving relative to the base body 1. The locking shaft 10 is provided with a square bar portion in its rear end, on which a lock plate 11 is mounted and firmly fixed thereto by tightening a bolt 12 threadably engaged with the rear end portion of the locking shaft 10.
A fan-shaped concave portion 14 is formed in a rear surface of an upper end portion of the door handle 13. Rotatably mounted in this concave portion 14 in an insertion manner is a front end portion of the locking shaft 10, so that the door handle 13 has its rear end portion pivoted to the front end portion of the locking shaft to 10 through a cross pivot 15 extending in parallel with the front surface of the door 2. In operation, when the door handle 13 is pushed down into the base body 1, a main body of the door handle 13 is embedded in a front concave portion 16 of the base body 1. In this embedded condition, a lower end portion of the door handle 13 projects downward beyond a lower end portion of the base body 1 to form a finger engaging portion which is engageable with a finger of the user to facilitate the pulling-out operation of the door handle 13 relative to the base body 1.
