Description

  The present invention relates to an apparatus for preventing money, goods, and the like from being stolen from a vending machine.

  Conventionally, as a device to prevent the theft of money and goods from vending machines, locking the door with a normal lock handle device can be easily unlocked due to unauthorized destruction, etc., resulting in damage such as theft. Separately from the handle device, an auxiliary lock device for a door (for example, refer to Patent Document 1) that locks the lock rod between the vending machine main body and the door, or locks the door. In addition to the first lock mechanism that mechanically unlocks, a second lock mechanism that electrically locks and unlocks the door is provided, and this second lock mechanism is activated by a starting means such as a timer. Such a locking device (see, for example, Patent Document 2) is known.

JP 2000-320213 A JP-A-8-212443

  However, in the case of the technique disclosed in Patent Document 1, since both the handle lock device and the lock rod are exposed to the outside, the resistance force against weak destruction of the lock mechanism itself is weak. In the case of the technique disclosed in Patent Document 2, the second lock mechanism uses components of the first lock mechanism, and a part of the components of the first lock mechanism is electrically locked / unlocked. For this reason, there is a problem that the door is opened in a relatively short time, for example, by breaking the hinge portion.

  Therefore, the present invention strengthens the locking system of the door of the vending machine so that it cannot be easily opened, increases resistance against unauthorized destruction, and makes the operability complicated. The purpose is to avoid.

In order to achieve the above object, the present invention provides an anti-theft device for a vending machine in which an operation part is exposed to the outside as a lock mechanism for locking one door whose peripheral side part is hinged to the vending machine body. And an outer key that locks the side edge of the door on the opposite side of the hinge, and a pair of upper and lower inner keys that do not expose the operation part and lock the upper and inner sides of the door. When the door is closed, the lock claw of each inner key automatically engages with each fixing bracket on the main body side, and the lock claw is fixed while the door is locked. This is done by releasing the lock claw of each inner key by a typical remote operation , and if this inner key is operated to the open side by an incorrect remote operation, a predetermined time is Automatically locks after a lapse As the timer back to is linked, further, on the front surface of the door of the vending machine, provided with a visual confirmation means for confirming the opening state of said key visually.
Then, for example, the outer key is used as a basic lock and the inner key is used as an auxiliary lock. In order to open the door, a key operation for releasing the outer key is performed, and then the inner key is opened by remote operation. . When closing the door, the door is closed and the inner key is automatically locked, and then the outer key is locked by a key operation or the like. Then, since the inner key cannot be visually recognized from the outside, even if it is attempted to be destroyed, it is difficult to destroy, and at the same time, there is no problem that impairs the beauty.

At this time, if the inner key is provided in a pair on the upper and lower sides of the door, it will be difficult to open the door due to the hinge breakage. It is preferable to provide a visual confirmation means for visually confirming the open state of. Here, as the visual confirmation means, for example, an indicator lamp that is not lit but is lit when opened can be applied.

  Even if the outer key is destroyed, the door will not open as long as the inner key is locked, and the location of the inner key is unknown, so even if you use a special tool to destroy the door, the time for destruction Is a long time, and has the deterrent effect of destruction itself. Even when the door is opened, the outer key requires a key operation, but the inner key is an electronic remote operation, so that the procedure is not particularly complicated. Also, when the door is closed, the inner key is automatically locked at the same time as the door is closed, so that only the outer key is operated, and it can be locked in the same procedure as before.

  In addition, if the inner key is provided as multiple independent locking mechanisms, it can be more resistant to breakage, etc., and visual confirmation means can be provided on the front of the door to visually recognize the opened state of the inner key. Thus, for example, when trouble occurs when opening the door, it can be used as a reference when determining whether the cause is the trouble of the inner key or the trouble of the outer key.

Embodiments of the present invention will be described with reference to the accompanying drawings.
Here, FIG. 1 is an external view of a vending machine to which the antitheft device according to the present invention is applied, FIG. 2 is an explanatory view with a door open, FIG. 3 is a perspective view showing an example of a lock unit, and FIG. It is an effect | action figure of the lock state of a lock unit.

  The anti-theft device for a vending machine according to the present invention enhances the anti-theft property by strengthening the door locking system so that the door cannot be easily opened, and also increases the resistance against unauthorized destruction. In addition, the operation is not complicated, and is characterized by combining an outer key as a basic key and an inner key as an auxiliary key, and releasing the inner key by electronic remote operation. .

  That is, as shown in FIGS. 1 and 2, the vending machine 1 is electronically unlocked by an external key 2 that is mechanically locked and unlocked by a key operation or the like and a remote control key 3. An inner key 4 is provided and a double lock structure is provided.

The outer key 2 is a lock mechanism that is generally used in the past, and an operation unit 2a that is operated by inserting a key is provided on the front surface of the door 5. For example, the operation is performed by inserting a key into the operation unit 2a. Then, the handle 6 pops out, and when the handle 6 is turned, the slider provided with the engagement hole 8 shown in FIG. 2 slides in the vertical direction, and the engagement hole 8 of the slider is fixed to the vending machine body 10 side. The tool 7 is engaged or disengaged.
The hooks 7 and the locking holes 8 are provided in a row along the vertical direction on the door 5 on the opposite side of the door 5 from the hinge portion 9 and on the peripheral edge of the vending machine main body 10.

  The remote control key 3 incorporates, for example, a button for operating a micro switch, a transmitter that oscillates infrared rays or electromagnetic waves by the operation of the micro switch, an electrical circuit, a battery, and the like. A signal can be sent to the unit 11.

The inner key 4 includes a control unit 11 that receives infrared rays and electromagnetic waves transmitted from the remote control key 3 and is connected to a power source (not shown), a solenoid-type lock unit 12 that is locked by the control unit 11, The lock unit 12 is provided with a substantially U-shaped fixing bracket 14 that can be freely engaged and disengaged. In this embodiment, the lock unit 12 is attached to the back side of the door 5, and the fixing bracket 14 is on the vending machine main body 10 side. Is provided inside.
A pair of the lock units 12 are provided at the upper and lower portions of the door 5, and these are controlled by a single control unit 11.

An example of the structure of the lock unit 12 is provided with a lock claw 13 that can swing around the pivot shaft 17 as shown in FIGS. 3 and 4, for example. When 13 is engaged with the fixing bracket 14, the lock claw 13 automatically swings to the lock side, and when the lock claw 13 swings to the lock position, the stopper pin 15 biased by a spring or the like is placed on the back surface of the lock claw 13. When the lock signal is released from the control unit 11, the stopper pin 15 is retracted from the back surface of the lock claw 13 by the solenoid operation, and the lock claw 13 is reversed. The structure is such that the swing regulation is released.
In addition, the structure of such a lock unit 12 is an illustration.

  In addition, an indicator lamp 16 (FIG. 1) is provided on the front surface of the door 5 as visual confirmation means for notifying that the lock unit 12 has been opened (unlocked). When the lock is released, the indicator lamp 16 is turned on.

The operation of the lock mechanism of the vending machine 1 will be described.
When the operator opens the door 5 of the vending machine 1, the handle 6 is popped out by inserting the key into the operation portion 2 a of the outer key 2 and operating the handle 6. Remove from. Next, the operator presses the button of the remote control key 3 to put the lock claw 13 of the inner key 4 in a free state.
At this time, since the opening of the lock unit 12 is indicated by the lighting of the indicator lamp 16, the operator can confirm it visually.

When the lock of the outer key 2 and the inner key 4 is released, the operator pulls the handle 6 of the door 5, whereby the lock claw 13 of the inner key 4 swings to the open side and the door 5 is opened.
In this opening operation, for example, when the door 5 is not opened, the operator can easily determine whether the inner key 4 or the outer key 2 is the cause by checking the indicator light 16. .

  Next, when the door 5 is closed, since the inner key 4 is automatically locked simultaneously with the closing of the door 5, the operator inserts the key into the operation portion 2a of the outer key 2 after closing the door 5. Work is completed just by operating. And the operation of the operator accompanying such a closing procedure is not different from the conventional one, and the procedure is not complicated.

  Also, in the closed state, for example, when the outer key 2 is illegally destroyed, the door 5 cannot be opened due to the presence of the inner key 4, and even if all the locking mechanisms are to be destroyed, the door 5 can be opened at a plurality of independent locations. Because there is a key and the presence or absence of the inner key 4 and the location of the lock unit 12 cannot be visually recognized from the outside, it cannot be easily destroyed, and moreover, a plurality of keys are located on the open side of the door 5. Since the upper portion, the side portion, and the lower portion are arranged and the gap is small, it is difficult to open the door 5 by breaking the hinge.

  As a combination of the remote control key 3 and the control unit 11, for example, if a unique ID number is assigned to each vending machine or each administrator, it is preferable to ensure security. It is also convenient if the remote control key 3 can be reissued even if it is lost.

The present invention is not limited to the above embodiment. What has substantially the same configuration as the matters described in the claims of the present invention and exhibits the same operational effects belongs to the technical scope of the present invention.
For example, specific configurations such as the lock unit 11 and the fixing bracket 14 are arbitrary, and the type of the vending machine 1 is also arbitrary.
Also, by linking a timer to the inner key 4, for example, if the remote control key 3 is accidentally operated to the open side, it automatically returns to the locked state after a required time of about 1 minute, for example. Alternatively, a timer may be used so that the inner key 4 is unlocked during the day and does not obstruct the operator's opening and closing work, and the locked state may be maintained for a certain period of time at night.

  In addition to the main outer key, an auxiliary inner key is provided as a lock mechanism for the door of the vending machine so that the inner key can be opened by electronic remote operation without exposing it to the outside. The inner key is automatically locked when closed, thereby improving the anti-theft property and improving the operability.
