Description

[Detailed description of the invention] The present invention relates to a door locking device for furniture such as a storage room.It is compact and has an extremely simple structure, and is capable of reliably and firmly locking and locking the door. It has been made possible.

Next, the details will be explained with reference to the illustrated embodiment. 1 is a furniture body such as a storage, 2 is a door attached to the doorway of the main body 1 with a hinge so that it can be opened and closed freely, and 3 is a screw 3' fixed to the upper edge of the door 2. The edge members 4 and 5 are made of synthetic resin and have a cross-sectional shape as shown in FIG. A return spring 9 is wound around the body of the latch, and a hook part 6a at the tip of the latch is attached.
protrudes rearward from the opening 3b of the back plate of the edge member 3, is urged by the return spring 9, and is latched onto the edge of the engagement hole 1a of the upper stile portion 1' of the furniture body 1.

As shown in FIG. 3, the edge member 3 has an eave-like cover plate projecting forward at a position corresponding to the top plate, and a lock mounting portion 10d is integrally formed with the synthetic resin close to the side of the pull portion 10a. The handle 10 is made by screwing the attachment parts 10b, 10b on both sides of the handle part 10a and the lock attachment part 10d to the top plate of the edge member 3 with screws 10', 10', respectively.
At the bottom of this handle part 10a, a latch actuation plate 11 having a handle part 11a on the lower surface has grooves 11b on both sides of the actuation plate, and a convex protruding from the inner surface of the attachment part 10b. Article 10c, 10
c so that it can slide forward and backward (the first
), the rear end of the latch actuating plate 11 penetrates into the groove of the edge member 3 through an opening provided in the front plate of the edge member 3,
Square engagement hole 11 bored in the latch operating plate 11
An engaging protrusion 6b protruding from the eccentric lower surface of the latch 6 engages with the edge of the hole c. (Figure 2). Second
In the figure, reference numeral 11d designates an escape groove drilled in the latch operating plate 11 into which the body of the latch 6 fits.

Therefore, when the latch actuating plate 11 is pulled forward by the handhold portion 11a, the latch 6 rotates in the direction of arrow A via the engagement protrusion 6b that engages with the engagement hole 11c, so that the hook portion 6a moves toward the main body 1. After being removed from the engagement hole 1a, the door 2 can be opened forward using the handle 10. At this time, the latch operating plate 11 is locked to the front edge of the cover plate of the pull portion 10a. Alternatively, the back surface of the latch 6 may be locked to the edge of the opening 3b of the edge member 3.

A cylinder lock 13 is fitted and fixed in the opening on the front surface of the lock mounting part 10d, and an operating rod 13b that moves laterally within the groove of the edge member 3 in conjunction with the rotor 13a has a key board with a cross-sectional shape. 14 is fixed with screws 14', and the key plate 14 is connected to the latch operating plate 11.
The latch actuating plate 11 extends in the direction with an appropriate distance from the plate surface of the latch actuating plate 11. When the cylinder lock 13 is locked in the closed state, the key plate 14 moves to the left via the operating rod 13b, and the locking plate 1 provided in a position corresponding to the front plate of the key plate 14 protrudes downward.
4a and 14a (FIG. 1) engage with groove-shaped engaging portions 11e and 11e provided on the projecting edges on both sides of the latch operating plate 11, so that the latch operating plate 11 is locked. In the figure, reference numeral 15 denotes a support plate attached to the lower surface of the key plate 14, the lower surface of which is slidably supported by the head of the latch mounting shaft 7. Reference numeral 16 denotes a cover provided on the front surface of the lock mounting portion 10d, and is attached by slidingly engaging the protrusion 16a provided on the inside of the rear edge with the engagement groove 17 provided at the upper and lower portions of the mounting portion 10d. covers the lock mounting portion 10d, and when the cylinder lock 13 is operated, moves to the right to expose the cylinder lock 13.

The door locking device of the present invention has a pull portion 10a having a latch operating plate 11 and a lock mounting portion 10 as described above.
Since the handle 10 integrally formed with d is attached to the front of the door 2, the locking device and the locking device can be configured extremely compactly, and can be easily attached to the door. Since the actuation plate 11 is directly actuated, the door can be reliably locked to the main door with a simple structure, and the cylinder lock 13 attached to the lock attachment part 10d as described above
A key plate 14 is connected to the operating rod 13b of the key plate 1.
4 in the direction of the latch actuating plate 11.
Extend it with an appropriate distance between it and the plate surface of 1,
When the cylinder lock 13 is locked, the locking plates 14a, 14a of the key board 14 lock both sides of the latch operating plate 11, so even if the latch operating plate is relatively wide, it will not become unlatched. This has practical effects such as ensuring that the lock is securely and securely locked.
