Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a safe lock device, and more particularly to a safe lock device in which the safety of the safe lock is further enhanced.

(Prior Art) Conventionally, for example, as shown in FIG. 3, an automatic vending machine 101 is provided with a bill and coin authenticity identifying device 102, and a safe 104 is removably provided in a safe housing portion 103 located therebelow. A lock device 105 for pulling out the safe is provided on the side wall of the safe housing portion 103.

In the system for collecting money in the safe 104 from the vending machine 101, the machine installer has a key to open the lock 107 of the vending machine rear door 106, and the key of the lock device 105 after the rear door 106 is opened is a safe collector. It was general to secure the safety by possessing. The recovered safe 104 is further provided with another lock (not shown) so that the safe collector cannot open the lock.

By the way, the lock used in the lock device is generally cheap, and its structure is often simple in that the lock plate is simply locked by the spring in the lock groove on the safe side.

However, in such a lock device, if a thin metal plate or the like is inserted into the gap between the side wall of the safe housing portion of the vending machine and the side wall of the safe, the lock plate may easily retract and the safe may be stolen. However, there is a defect that the person who stole the safe can easily withdraw money by destroying it.

This kind of defect can be solved by not inserting a safe thin plate etc. by projecting a flange covering the above-mentioned gap on the front of the safe, but if such a flange is provided, it will be arranged when transporting a large number of safes. It is difficult to stack and it hinders handling work.

Further, if the gap between the side wall of the safe compartment and the side wall of the safe is sufficiently small, it becomes difficult to insert and remove the safe, and if this is to be done smoothly, it is necessary to increase the working precision of the safe compartment and the safe, and it is expensive. Become.

(Object of the Invention) The present invention has been made by paying attention to the defects of the conventional safe lock device as described above, and it is easy to insert and remove the safe and does not require high working precision, An object of the present invention is to provide a safe lock device in which a lock plate does not retract even when a thin metal plate or the like is inserted into a gap between the safe side wall.

(Outline of the Invention) In order to achieve the above object, the present invention has the following configuration.

A safe lock device for locking a safe that can be stored and taken out by moving in and out of a safe storage unit as a vacant space at a storage position, centering a fulcrum at one end on one inner wall of the storage unit. And a lock plate which is rotatably supported and has an inclined portion which allows the safe to pass while the safe is housed in the housing, and the lock plate is elastically biased toward the inside of the housing. A spring, and a lock groove provided on the side wall of the safe so that the other end of the lock plate protruding inward by the biasing force of the spring fits when the safe is stored in the storage portion, A safe lock device having a mechanism for unlocking the lock plate by rotating the lock plate about the fulcrum in a direction opposite to a biasing direction of a spring, A cutout is formed in the inclined portion of the plate, and the cutout is formed between the inner wall of the safe and one side wall of the storage portion when the lock plate is in a state of protruding toward the inside of the storage portion. It has a shape capable of communicating with the gap.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

Here, in order to help understanding of the present invention, a conventional safe lock device will be briefly described.

FIG. 2 shows a conventional safe lock device, which is a safe storage unit 1.
Of the lock plate 3 provided on the side wall (inner wall) 2 of the same is rotatable about the fulcrum 4 in the opening direction (counterclockwise direction in the figure) or in the closing direction (clockwise direction = inward direction in the figure). In addition to the construction, the spring 5 urges it toward the lock groove 8 formed in the side wall 7 of the safe 6 so that it can be locked.

With such a configuration, when the safe 6 is inserted into the safe housing unit 1, the end wall (not shown) of the safe 6 pushes the inclined portion 3a on the back side of the lock plate 3 to rotate the lock plate 3 in the opening direction. After that, when the safe 6 is stored in a predetermined position, the lock plate 3 is pushed by the urging force of the spring 5.
Rotates in the closing direction to lock the safe 6 by locking the other end of the lock plate 3 in the lock groove 8 of the safe 6.

However, when the thin metal plate 9 or the like is inserted into the gap C between the side wall 2 of the safe housing part 1 and the side wall 7 of the safe 6, the inclined part 3a of the lock plate 3 is pushed and the plate 3 rotates in the opening direction. As described above, there is a defect that the safe 6 is stolen when it moves (indicated by a chain double-dashed line in the figure).

Therefore, in the safe lock device according to the present invention, as shown in FIG. 1 as one embodiment, a notch 10 communicating with the gap C between the safe side wall 7 and the safe storage part side wall 2 is formed in the inclined portion 3a of the lock plate 3. Configured to form.

Now, when the metal thin plate 9 or the like is inserted into the gap C between the safe side wall 2 and the safe side wall 7, the tip of the metal thin plate 9 enters the notch 10 and the lock plate 3 is rotated even if the metal plate 9 is further pushed. Therefore, the safe 6 is not stolen without the plate 3 retracting.

Since it is possible to prevent the safe 6 from being stolen without projecting a flange that covers the gap C on the front surface of the safe 6, it is easy to stack and stack the safes 6 easily even when they are transported. Is also easy.

Further, since the conventional locking device can be simply machined without reducing the gap C between the safe housing side wall 2 and the safe side wall 7, it is not necessary to increase the working precision and the safe 6
Although the lock device is easy to insert and remove and is inexpensive, it is possible to reliably prevent theft. The lock is released by rotating the lock plate 3 outward (counterclockwise) around the fulcrum 4, but the lock is unlocked by a lock provided outside the safe housing portion. Of course.

As described above, in the present invention, the unlocking due to mischief using a thin plate is prevented by the extremely small number of parts (the lock plate 3 with the notch, the fulcrum 4, the spring 5, the unlocking means), and the structure of each part is also extremely simple. Therefore, the cost becomes easier. Moreover, since the existing lock plate 3 as shown in FIG. 2 is provided with the notch 10 or is replaced with the lock plate 3 provided with the notch 10, it is possible to prevent mischief or theft, so that it is a highly practical device. Is.

(Effects of the Invention) As described above, according to the present invention, high work precision is not required, and the lock plate does not retract even when a thin metal plate or the like is inserted into the gap between the safe side wall and the safe side wall. Therefore, it is possible to realize a safe lock device that is inexpensive and highly safe.
