DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine auxiliary lock which is attached to the outside of a vending machine separately from a lock built in the vending machine.

[0002]

2. Description of the Related Art The door of a vending machine is openable with respect to the main body and has a built-in lock. However, the door is attached to the outside of the vending machine in order to strengthen theft prevention of goods and sales. Conventionally, various auxiliary locks have been proposed.

For example, an auxiliary lock (an anti-theft lock) according to Utility Model Registration No. 3018664 includes a main body fixing member (a bottom plate and a protective bracket supporting member) fixed to the bottom of a main body of a vending machine, and a front of a door. The main body mount is provided with a box-shaped mounting portion (protection bracket support member) that is opened upward so that the door lock is inserted. The locking member is provided so as to be able to protrude and retreat behind the mounting portion so as to engage with the back of the door locking member.

[0004]

Since the above-mentioned auxiliary lock has a structure in which a door locking member is attached to and detached from a main body mounting member, it is complicated to lock and unlock in supply of goods, collection of sales proceeds, and the like. There was a problem. In addition, since the structure of the above-mentioned auxiliary lock can be easily inferred from the external appearance, there is a problem that the auxiliary lock may be attempted to be broken.

The present invention has been made in view of such conventional problems, and has as its object to provide an auxiliary lock for a vending machine which can be easily locked and unlocked and whose structure is difficult to infer from its appearance. .

[0006]

SUMMARY OF THE INVENTION The features of the present invention for solving the conventional problems as described above and achieving the intended purpose are as follows.
A main body fixing member fixed to a main body of the vending machine, a door locking member protruding forward of a door of the vending machine, a locking member for locking or releasing the door locking member, and a predetermined key An auxiliary lock for a vending machine, comprising a locking member for operating the locking member through the vending machine. A connecting shaft for vertically rotatably connecting the door locking member, the front locking portion is formed in a hollow shape having a closed front side portion, and an opening is provided on the back side; An engaging portion is provided inside and is fixed to a front side of a door of the vending machine, and is engaged with the engaging member through the opening.

The door locking member is formed in a substantially L-shaped cross-sectional shape including a connecting portion disposed on the outer peripheral side of the door of the vending machine and a projecting portion projecting forward of the door. It is preferable that the opening of the stopper, the locking member and the locking member are provided on the projecting portion, and the connecting shaft is provided on the rear end side of the connecting portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numerals 1 and 2 denote a main body and a door of a vending machine to which an auxiliary lock is attached. The main body 1 is installed via supporting legs 4, 4,..., And the door 2 is connected to the main body 1 via a hinge or the like. It is designed to open forward. In the figure, 10, 20, 30, 40, 50, and 60 are a main body mounting member, a door locking member, a locking member, a locking member, a connecting shaft, and a door mounting plate which constitute the auxiliary lock.

The main body mounting member 10 includes a rear fixing portion 11 and a front connecting portion 15. On the bottom surface of the fixing portion 11, fixing screws to be screwed with fixing bolts 19, 19. A hole is provided so as to be fixed to the upper surface of the main body 1 of the vending machine from the inside. The connecting portion 15 is formed in a concave shape that opens upward and forward.

The door locking member 20 has a projection 2 projecting downward.
1 and a connecting portion 25 protruding to the rear side. And the door locking tool 20 is a front surface,
The upper and lower surfaces and both side surfaces (front side portion) are formed in a closed hollow box shape, and a vertically long opening portion 23 is provided on the rear surface (back side portion) of the protrusion 21.

The connecting shaft 50 is formed in a cylindrical shape that is long in the left and right directions, and has a central portion connected to the connecting portion 2 of the door locking member 20.
5 are embedded in the rear end portion, and both end portions are embedded in the connecting portion 15 of the main body fixture 10. Thereby, the door locking device 20
Is rotatably connected to the main body mounting device 10 and rotates vertically to the front surface of the vending machine so that the connecting portion 25 of the door locking member 20 is disposed above the door 2 of the vending machine. Protruding part 21
Has a structure projecting forward of the door 2, but the structure is not easily guessed from the appearance.

The door mounting plate 60 is provided with the projecting portion 2 of the door locking member 20.
1, and is fixed to the front surface of the door 2 of the vending machine via fixing screws 69 and the like. In the center of the door mounting plate 60, a pin-shaped engaging portion 63 is fixedly protruded forward and is inserted from the opening 23 into the inside of the projecting portion 21 of the door locking member 20. I have.

The locking member 40 (cylinder lock) is fixed to the front surface of the projection 21 of the door locking member 20 with the keyhole portion exposed to the outside. The locking member 40 is provided with a turning part 48 (cylinder barrel) that is turned through a predetermined key, and the turning part 48 is arranged inside the protruding part 21 of the door locking tool 20. And a locking member 30
Has been fixed. The locking member 30 is formed in a hook shape, and rotates left and right to engage with the engaging portion 63 of the door mounting plate 60.

When the auxiliary lock constructed as described above is locked, after closing the door 2 of the vending machine, the door lock 20
Is pivoted downward so that the projection 21 projects forward of the door 2, the back surface of the projection 21 is brought into contact with the door mounting plate 60, and the locking member 30 is pivoted to the left with a predetermined key. Engaging part 6
3 and the door lock 20 is locked to the door 2.
On the other hand, when canceling, the operation is performed in the reverse of the above-described operation.

In the above-described embodiment, the case where the auxiliary lock is mounted on the upper surface of the vending machine is shown, but the auxiliary lock may be mounted on the side surface or the bottom surface of the vending machine.

[0016]

As described above, in the auxiliary lock for a vending machine according to the present invention, the door locking device is rotatably connected to the main body mounting device via the connecting shaft, so that the door locking device can be used. There is no need to attach and detach, making locking and unlocking easier. In addition, a connecting shaft is embedded in the main body mounting member and the door locking member, a locking member is provided inside the door locking member, and the engaging portion fixed to the front side of the vending machine door is a door locking member. It is difficult to infer the structure from the appearance by engaging with the locking member through the opening, and therefore, it is difficult to break.
