DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the embodiment shown in FIGS. 1 to 16 will be described. The door lock member A is mainly composed of a main body case 1, a lock plate 2, a handle 3, and a connection shaft 13. The main body case 1 is formed in a vertically long rectangular shape, and has a vertically long storage recess 14 opened to the front side. The storage recess 14 stores the vertically long handle 3, and a push button 15 is stored below the storage recess 14. A through hole is formed in the upper part of the storage recess 14 so as to penetrate from the storage recess 14 to the back surface side, and the connection shaft 13 is rotatably inserted through the through hole. A pivot shaft 16 whose axis direction is orthogonal to the coupling shaft 13 is mounted on the storage recess 14 side of the coupling shaft 13, and the upper part of the handle 3 is rotatably connected to the pivot shaft 16. 3 is rotatable in a direction to enter and exit the storage recess 14. Also, the handle 3 is put out of the storage recess 14 and the handle 3 is connected to the connecting shaft 1.
By pivoting about 3, the connecting shaft 13 with the handle 3 is rotated.
Rotates. A spring 17 such as a coil spring is interposed between the upper portion of the handle 3 and the end face of the connection shaft 13, and is biased so that the handle 3 projects from the storage recess 14.

At the back of the push button 15 provided in the lower part of the storage recess 14 of the main body case 1, a locking plate 18 which is turned by the pressing of the push button 15 is rotatably mounted. The locking projection 19 is detachable from a locking notch 20 at the lower end of the handle 3. The locking plate 19 is urged by a spring 21 such as a coil spring so as to rotate in a direction in which the locking projection 19 is locked to the locking notch 20, and the push button 15 is formed of a coil spring. It is urged to the front side by a spring 22.

When the lower part of the door locking member A is pushed into the back side from this state, the guide surface 10 of the movable locking member 9 hits the lower opening edge 7 as shown in FIG.
The movable locking member 9 moves inward against the movement of the movable locking member 9. When the pusher is further pushed in from this state, the movable lock 9 moves over the opening edge 7 and moves outward by the urging force of the spring 42, as shown in FIG. 7 on the back side. In this state, the screw 11a as the fixing member 11 is tightened as shown in FIG. 16 so that the movable locking member 9 is fixed so as not to move, and the door locking member A is attached to the door 4. In the case of the present embodiment, when the movable locking member 9 moves outward, the moving locking member 9 also moves to the front surface side and moves.
Are strongly locked on the back side of the opening edge 7.

The door lock member A is attached to the door 4 as described above, and the handle 3 is rotated about the connection shaft 13 with the handle 3 protruding to the front side, so that the handle 3 and the connection shaft 13 are joined together. The lock plate 2 can be rotated to lock or unlock. When the handle 3 is turned so as to turn in the horizontal direction, the lock is unlocked. When the handle 3 is turned so as to overlap the front side of the main body case 1, the lock plate 2 projects to the side and the lock plate 2
3 is the edge 45 of the cabinet 45 as shown in FIG.
a and locked. When the lock plate 2 is rotated in the locking direction, the front end of the lock plate 2 swings so as to gradually approach the surface side, and in the locked state, the front end of the lock plate 2 comes into close contact with the edge 45a. And is locked so that the door 4 does not rattle. By pushing the handle 3 to the back side in the locked state, the handle 3 is stored in the storage recess 14 of the main body case 1, locked by the locking plate 18, and stored and held.

Next, the embodiment shown in FIGS. 17 to 19 will be described. In the case of the present embodiment, the movable locking member 9 is movable along a plane parallel to the surface of the main body case 1. The bottom surface of the movable locking member 9 is a surface parallel to the surface of the main body case 1, and the rear surface side of the main body case 1 is provided with a flat mounting surface 46 parallel to the surface of the main body case 1. 9 is mounted on the flat mounting surface 46 and
Are movable inward and outward. The screw 11 a serving as the fixing member 11 is screwed into the screw hole 41 via the long hole 40 of the movable locking body 9. Further, a spring housing portion 48 is provided in the movable locking member 9, and a spring 47 such as a coil spring is stored in the spring storing portion 48, and the movable locking member 9 is moved outward by the spring 47. It is energized to do.

The door lock member A constructed as described above is attached to the door 4 in the following manner. The door lock member A is inserted into the mounting opening 5 from the front side of the door 4, but the upper part of the door locking member A is first inserted into the mounting opening 5, and the upper part of the opening edge 7 of the mounting opening 5 is inserted. It is inserted into the gap 36 to lock the fixed locking body 34 on the back surface of the opening edge 7. When the lower part of the door lock member A is pushed into the back side from this state, the state shown in FIG.
As shown in FIG. 9A, the guide surface 10 of the movable locking member 9 hits the lower opening edge 7, and the movable locking member 9 moves inward against the spring 47. When the movable locking member 9 is further pushed in from this state, it moves beyond the opening edge 7 and moves outward by the urging force of the spring 47 as shown in FIG. Locks on the back side of the opening edge 7. In this state, the screw 11a as the fixing member 11 is tightened as shown in FIG.
