Abstract

PROBLEM TO BE SOLVED: To provide a lock mechanism of a door which is resistant to bar attack of a financial automation equipment. SOLUTION: This equipment device having a theft prevention reinforcing door is provided with a lock receiver 11 on a device main body 1 side and a lock shaft 13 energized by a coil spring 14 on a door 2 side thereof. The lock shaft 13 is inserted in a lock shaft bracket fixed on a door 2 and can slide toward a locking hole of the lock receiver 11. Normally, a tip 13a of the lock shaft 13 is locked by a lock plate 16 erected on a screen plate 8 of the door 2, and a lock plate 17 guided by a shoulder screw is put on a top face of a rear end 13b thereof. At the time of destruction and attack, the lock shaft 13 is released from the lock plate 16 which is deformed together with the screen plate 8, slides due to external force of the coil spring 14, and is locked into the locking hole of the lock receiver 11, and the lock plate 17 drops by the length of a long hole to suppress the movement to the right and left of the rear end 13b of the lock shaft 13.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an anti-theft device, in particular, a lock mechanism capable of maintaining a locked state even if it is subjected to a destructive attack in a financial automation device, and at least one lock mechanism for the door. The present invention relates to a security device that is provided in more than one place.

[0002]

2. Description of the Related Art Conventionally, the door of an apparatus in consideration of theft resistance is
As shown in FIGS. 3 (appearance perspective view) and 4 (front view of the inner surface of the door), one of the apparatus main body 1 and the door 2 is rotatably supported by a plurality of hinges 3, and the other is an upper lock 4a. The structure was locked at three places of the lateral lock 4b and the lower lock 4c and opened and closed by the handle 4. In addition,
Reference numerals 5, 6, and 7 denote an upper lock shaft, a lateral lock plate, and a lower lock shaft, respectively, and 8 denotes a blind plate provided on the outer peripheral edge of the door 2.

[0003]

However, in the door lock mechanism having the above structure, when the apparatus is in the locked state (see FIG. 4), the portion A (the center of A ') or the portion B (the center of B') is moved. When a destructive attack is caused by a bar or the like, there is a problem that the door is greatly deformed and the lock is released in a short time as the distance between A 'and B' is longer.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an apparatus having the anti-theft structure,
A first lock plate is erected inside the blindfold plate of the door, and the front end is locked by the lock plate and guided by a lock shaft bracket fixed to the inner surface of the door,
A lock shaft, which is always urged by a coil spring toward a lock hole of a lock receiver provided in the main body of the apparatus, and a second lock plate having a structure capable of being dropped by its own weight by a certain distance on its rear end is mounted. This is a configuration in which: When the blind plate is subjected to a destructive attack by a bar or the like, it is deformed together with the first lock plate and released from the lock, and the lock shaft slides and engages with the locking hole of the device main body. On the other hand, the second lock plate prevents the rear end of the lock shaft from moving left and right by falling by a certain distance by its own weight.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a main part front view of a door lock mechanism according to the present invention as viewed from the inside. 3, the same parts as those in FIGS. 3 and 4 are denoted by the same reference numerals, and a lock receiver 11 having a locking hole 11a is newly provided in at least one or more places in the apparatus main body 1. A lock shaft 13 slidably inserted into a lock shaft bracket 12 having a U-shaped cross section fixed by welding or the like and slidably urged toward the locking hole 11a is provided inside the door 2. . More specifically, reference numeral 14 denotes a coil spring, which is pressed between a washer 15 fixed to the lock shaft 13 and one of the vertical sides 12a of the lock shaft bracket 12. Reference numeral 16 denotes a first lock plate having an L-shaped cross section protruding from the inside of the blind plate 8 of the door 2, and 17 denotes a shoulder screw (two in the illustrated case) provided on the door 2.
The lock shaft 13 is a second lock plate guided in the long hole 17a by the lock hole 13. In a normal state, the left end 13a of the lock shaft 13 abuts on the first lock plate 16 as shown in FIG. , The right end 13b is the second
Of the lock plate 17 is placed.

However, when the burl 19 is inserted into the gap of the blind plate 8 of the door 2 and pulled in the direction of the arrow (see FIG. 2B), the blind plate 8 is deformed outward. As a result, the first lock plate 16 also shifts outward at the same time, and the lock shaft 13 that has hitherto contacted and locked the first lock plate 16 is released, and the washer 15 is moved to the left by the reaction force of the coil spring 14. It moves and comes into contact with the left standing side 12b of the lock shaft bracket 12 and stops. As a result, the tip 13a of the lock shaft 13 stops in the locking hole 11a of the apparatus main body 1. On the other hand, the lock shaft 13
The second lock plate 1 placed on the rear end 13b
Numeral 7 falls by its own weight by the length of the long hole 17a, stops at the position of the shoulder screw 18, and regulates the lateral movement of the lock shaft 13.

According to the above embodiment, a lock receiver 11 is newly provided on the apparatus body 1 side, and a first lock plate 16 is protruded from the blind plate 8 on the door 2 side, so that the lock receiver 11 is always received by the coil spring 14. Since the lock shaft 13 urged toward the lock hole 11a and the second lock plate 17 for suppressing the lock shaft 11 are provided, the lock shaft 13 has the tip 13a even if it is subjected to a crowbar breaking attack.
Is locked in the locking hole 11a of the apparatus main body 1 and the rear end 13b has the effect of suppressing left and right movement by the lock plate 17. By providing them at least at one or more locations, there is an advantage that the durability time during a destructive attack can be extended.

[0008]

As described above, according to the present invention,
The following effects are obtained. The lock mechanism of the door according to the present invention is provided at least at one or more locations susceptible to a crowbar destruction attack and the like, in addition to the conventional anti-theft lock structure, so that the anti-theft security is improved and the The durable time can be extended, and a more secure security structure for financial automation equipment can be provided.
