DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an anti-theft device for various vending machines.

[0002]

2. Description of the Related Art As a conventional anti-theft device of this kind, there is one disclosed in Japanese Utility Model Registration No. 3018664.
Although not specifically shown, the conventional anti-theft device is entirely made of sheet metal and has a base fixed to a bottom plate of a vending machine,
It consists of two parts: a vending machine door and a protective body facing the vending machine. The former base has a rectangular holder part whose upper surface is open and receives the lower part of the protective body inside, and a lower surface of a bottom plate of the vending machine. A lock portion is slidably disposed on the base portion, and a tip portion of the lock piece is elastically moved toward the inside of the holder portion by a constant spring pressure. Along with the urging, a padlock latch is set up at the border between the base and the holder.

[0003] The latter defender has a vertically long rectangular shape, and a lock hole is formed on the back side thereof to allow the leading end of the lock piece to enter, and a padlock is cooperated with the latch. It is configured to provide a latch for attachment.

In actual use, the door of the vending machine is opened, a through hole is formed at a predetermined position on the bottom plate of the vending machine, and the base portion of the base is utilized by using the through hole. After fixing to the lower surface of the bottom plate of the vending machine via bolts and nuts, the door is closed again and locked by the locking means provided in the vending machine itself, and then the L-shaped operation rod is moved toward the base portion. , And while the tip of the lock piece entering the inside of the holder is retracted against the urging spring pressure, the lower part of the protective body is inserted into the holder and the lock is retracted by the operating rod. Is released, the tip of the lock piece again enters the inside of the protection body from the lock hole, and locks the protection body to the holder of the base.

[0005] Then, if a padlock is attached to the latch on the base side and the latch on the protective body side and then locked, under the double lock state of the padlock and the lock piece, the protective body is attached to the holder of the base body. Will be locked to the vending machine door, so even if the locking means of the vending machine itself is destroyed and the door is forcibly opened, Since the opening of the door is prevented, the money or goods in the vending machine can be prevented from being stolen.

[0006]

However, in the conventional anti-theft device, as described above, a configuration is employed in which the base portion of the base is simply fixed to the lower surface of the bottom plate of the vending machine with bolts and nuts. If there is a considerable distance between the bolt and nut and the holder, the base of the base will bend easily and the base will be easily bent just by kicking the armor from above. In practice, it does not provide sufficient anti-theft measures because the face-to-face relationship can no longer be maintained. For this reason, it is conceivable to increase the thickness of the base and the protective body, but this time, due to this, the entire device becomes unnecessarily large, so depending on the size and installation environment of the vending machine, etc. In some cases, there is a risk that usage will be restricted and costs will rise unnecessarily.

[0007] The use of the slide-type lock piece can be applied to the case where the protective body is inserted into the holder, or when the protective body is pulled out from the holder for replenishment of goods or the like.
In each case, the lock piece must be retracted against the biasing spring pressure by a blind operation using an operation rod, so that the operability is not always good. In addition, fixing the base portion of the base to the lower surface of the bottom plate of the vending machine, in addition to the above-mentioned bending problem, also makes it difficult to align the mounting hole on the base portion side with the through hole on the bottom plate side. there were.

[0008]

SUMMARY OF THE INVENTION The present invention has been developed in order to effectively solve the problems of the conventional anti-theft device, and includes a base fixed to a bottom plate of a vending machine, and a vending machine. The vehicular vending machine has a holding member which is in contact with the lower surface of the bottom plate of the vending machine. The vending machine has a base portion in contact with the top surface of the bottom plate of the vending machine, and the bottom portion of the vending machine is sandwiched between the base portion and the holding member from above and below in accordance with the thickness of the vending machine. While fixing to the bottom plate of the vending machine,
A lock shaft is provided on one of the holder portion of the base body and the protection body, and a lock piece is provided on the other side, which is provided with a lock piece which is disengaged from the lock shaft by a key operation from the front.

Therefore, according to the present invention, the base is firmly fixed to the bottom plate of the vending machine in accordance with the thickness of the base by obtaining the vertically held state by the base and the holding body. Therefore, even if the armor is kicked with a foot or a large force is applied with a bar or the like, the base itself will never bend. By maintaining it, it is possible to reliably prevent unreasonable opening of the door. In addition, since the lock piece can be engaged and disengaged from the lock shaft exclusively by operating the key from the front side of the device, the operability is greatly improved.
