DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a
The present invention relates to a vending machine antitheft device for preventing an outer door from being intentionally opened.

[0002]

2. Description of the Related Art FIGS.
Are known. In the figure, 1 is a main body case of a vending machine, and 2 is an outer door for opening and closing the front surface of the main body case 1. Reference numeral 3 denotes an antitheft device, which is constituted by a latch 4 and a chain 5. The latch 4 comprises a lock body 41 and a latch 42.
The lock main body 41 has a substantially U-shape with a space 41b provided between the legs 41a, and the legs 41a have latch holes 41c formed on the same center line. The latch 4 is a latch 4 held on one leg 41a.
2 is pushed into the other leg 41a through the space 41b to be in a locked state. When the key 43 is inserted into the keyhole of the lock body 41 and rotated as shown in FIG. 5, the latch 42 moves to the side of one leg 41a. As a result, the space 41b is opened to be unlocked. In this case, the back surface of the lock body 41 is fixed to the outer door 2 with a screw member while the back surface of the lock body 41 is brought into close contact with the outer door surface. The antitheft device 3 inserts one end of the chain 5 attached to the main body case 1 by the fixing bracket 51 into the open space 41b of the unlocked lock main body 41 when the outer door 2 is closed and locked. 6 through the ring of chain 5 as shown in
2 is pushed in and the latch 4 is locked. As a result, even if the lock device (not shown) provided on the opening / closing lever portion of the outer door 2 is broken and the outer door 2 is intentionally opened, the chain 5 can prevent the outer door 2 from opening, thereby preventing the stored goods and money from being stolen.

[0003]

However, the conventional antitheft device has a drawback that the outer door is intentionally opened by cutting the chain with cutting scissors or the like. Further, even if the chain is not broken, the outer door is slightly opened by breaking the locking device of the lever portion, so that there is a problem that a stick or the like is inserted and misplaced from this gap. SUMMARY OF THE INVENTION It is an object of the present invention to provide a vending machine antitheft device which solves the above-mentioned drawbacks and disadvantages and more reliably secures the vending machine.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention has a substantially U-shape, and has a latch hole in each of two opposing legs with a space therebetween. A lock body fixedly installed on one side, a latch inserted and held in a latch hole formed in one leg of the lock body, and inserted into a latch hole formed in the other leg through the space; A key operated by being inserted into a keyhole formed in the other leg of the lock main body, and the latch held in the bolt hole of one leg of the lock main body is passed through the space to the other leg of the lock main body. A latch that is locked by being inserted into a latch hole, and is unlocked by inserting and rotating a key into a key hole formed in the other leg of the lock body, and the latch is released from the latch hole of the other leg. Use a lock In the antitheft device for an automatic vending machine was,
The lock is fixedly installed on the main body case or the outer door on the side opposite to the side on which the latch is fixedly installed, and is inserted into or removed from the empty space of the lock body according to opening and closing of the outer door, and the outer door is closed. At the time of formation, a latch with a latch hole formed substantially on the same center line as the latch hole formed on both legs of the lock body is provided, and when the outer door is closed, the latch held on one leg of the lock body is emptied. The latch is fixed to the lock body by being inserted into the latch hole of the other leg through the latch hole of the inserted latch and locked, and in addition, the latch is locked when the outer door is closed. It is assumed that a cover that covers the lock body is provided integrally with the tool.

[0005]

[Action] Since the latch is inserted into the lock body and locked, it is not easy to break the latch and open the outer door. In addition, the lock is covered with a cover, so it is extremely difficult to break the lock. is there. In addition, since there is no gap for inserting a stick or the like when the latch is not broken, mischief can be prevented.

[0006]

1 and 2 show an embodiment of the present invention, in which the same or similar parts as those in FIGS. 3 to 6 are denoted by the same reference numerals. 1 and 2, in this case, the antitheft device 6
The same latch 4 as that in the conventional antitheft device is fixedly installed on the front side surface of the main body case 1. Reference numeral 7 denotes a hook having an oval hole 7a at the center, and a base end portion of which is fixed to a cover 72 forming a mounting bracket 71. Then, it is fixed to the outer door 2 by the screw member 73 via the mounting bracket 71.

In the above-described configuration, when the outer door 2 is in the closed state, the latch 7 is inserted into the space 41b of the lock body 41, and the latch hole 7a is inserted into the latch hole 41c.
Align with the same center line. When the latch 42 is pushed in, the latch 42 penetrates the latch hole 7a, engages with the latch hole 41c of both legs 41a, is locked, and the latch 4 is locked. In this locked state, the lock body 41 and the latch 7 are covered with the cover 72. Therefore, the antitheft device 6 is extremely hard to break and is held in such a state that it is not easily tampered. Even if the lock device provided on the opening / closing lever of the outer door is broken, the outer door 2 is closed by the antitheft device 6. It is kept in a formed state and does not produce a gap that is tampered with. When the outer door 2 is opened, if the key 43 is inserted into a keyhole provided on the lower surface side of the lock body 41 and rotated, the latch 42 comes out of the latch hole 7a and moves upward. The door 2 is easily separated from the lock body 41 without any trouble.

[0008]

According to the present invention, the lock body is formed in a substantially U-shape, has a latch hole in each of the opposite legs across the space, and is fixedly installed in one of the main body case and the outer door. And a latch inserted and held in a latch hole formed in one leg of the lock body and inserted into a latch hole formed in the other leg through the space, and the other leg of the lock body. The lock is formed by inserting a key that is operated by being inserted into the formed keyhole, and by inserting the latch held in the latch hole of one leg of the lock body into the latch hole of the other leg through the space. A vending machine using a latch which is unlocked by inserting a key into a keyhole formed on the other leg of the lock body and rotating the key to release the latch from the latch hole of the other leg. Smell theft equipment The the side where the yoke lock is fixedly installed fixedly mounted to the main body case or outer door opposite,
According to the opening and closing of the outer door, a latch hole is formed which is inserted into or removed from the cavity of the lock body and which is aligned with substantially the same center line as a latch hole formed on both legs of the lock body when the outer door is closed. When the outer door is closed, the latch held on one leg of the lock body is inserted into the latch hole on the other leg through the latch hole of the latch inserted into the space, and locked. By fixing the latch to the lock body, the antitheft device eliminates the weak points when using a conventional chain.Furthermore, the latch incorporates a cover that covers the lock body together with the latch when the outer door is closed. , The outer door is kept in a state in which the outer door is extremely hard to be broken in a closed state and hard to be tampered with. Therefore, the vending machine can secure a very high level of safety.
