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 door locking member, wherein the door locking member is formed in a hollow shape having a closed front side portion, and the main body mounting member is provided on the back side. An opening into which the front end of the vending machine is inserted is provided, and a connection shaft that is connected to the front of the vending machine so as to be rotatable vertically is provided inside the door lock and at the front end of the main body attachment. Equipped,
The locking member is provided at a front end of the main body attachment, and an engagement portion for engaging with the locking member is provided inside the door locking member.

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 support legs 4, 4. It is designed to open forward. In the figure, 10, 20, 30, 40, and 50 denote a main body mounting member, a door locking member, a locking member, a locking member, and a connection shaft that constitute the auxiliary lock.

The main body mounting member 10 is formed in a hollow box shape which is long in the front and rear direction and whose upper surface and side surfaces are closed. On the rear upper surface side, fixing nuts 18, which are screwed with fixing bolts 19, 19,. Are fixed to the bottom surface of the main body 1 of the vending machine from the inside, and the front end protrudes forward from the main body 1. On the upper surface side of the front end portion of the main body mounting member 10, locking member support holes 13 are provided vertically penetrating, and connecting shaft insertion holes 15 are provided on both left and right side surfaces of the front end portion. 15 are provided penetrating right and left.

The door locking member 20 is formed in a hollow shape in which a front surface, an upper surface, and both side surfaces (front side portions) are closed.
An opening 21 is provided on the back surface and the bottom surface (back side portion),
The front end of the main body fixture 10 is inserted through the opening 21. A concave engaging portion 23 opened downward is provided on the inner upper surface of the door locking member 20 so as to align with the engaging member support hole 13, and a connecting shaft opened inward on both inner side surfaces. The buried holes (screw holes) 25 are provided so as to be aligned with the connection shaft insertion holes 15.

The connecting shafts 50, 50 are formed to face left and right with bolts. The connecting shafts 50, 50 are rotatably inserted into the connecting shaft insertion holes 15, 15 of the main body mounting member 10, and are connected to the door locking member 20. It is screwed and fixed to the shaft insertion holes 25, 25.
As a result, the door locking device 20 is rotatably connected to the main body mounting device 10, rotates vertically to the front surface of the vending machine, and projects forward of the door 2. Does not allow the structure to be easily guessed.

The locking member 30 is formed in an L-shaped cross-sectional shape including an upwardly projecting portion and a rearwardly projecting portion. The upwardly projecting portion is slidably inserted vertically into the engaging member support holes 13, 13. And is mounted inside the body mounting fixture 10,
The upper end of the engaging member 30 projects and retreats from the upper surface of the front end of the main body attachment 10, and engages with the engagement portion 23 of the door lock 20.

The locking member 40 (cylinder lock) is fixed to the rear side surface portion of the main body attachment 10 with the keyhole portion exposed to the outside. The locking member 40 is provided with a rotating portion 48 (cylinder barrel) that is rotated via a predetermined key. The rotating portion 48 is disposed inside the main body attachment 10 and has a tip portion. The cam 39 is fixed. The cam 39 is formed in the shape of a disc with a rotating shaft eccentric, and slidably abuts on the lower surface of the rear protruding portion of the locking member 30 so that the locking member 30 projects up and down and retreats. Has become.

When the auxiliary lock constructed as described above is to be locked, after closing the door 2 of the vending machine, the door lock 20 is closed.
Is turned upward to protrude forward of the door 2, the locking member 30 is protruded upward by a predetermined key and engaged with the engaging portion 23, and the door locking device 20 is attached to the main body mounting device 10. Lock against. On the other hand, when canceling, the operation is performed in the reverse of the above-described operation.

Although the above embodiment shows the case where the auxiliary lock is attached to the bottom of the vending machine, the auxiliary lock may be attached to the side or top of the vending machine.

[0015]

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, the front end of the main body fixture is inserted inside the door lock, the connecting shaft is provided inside the door lock and the front end of the main body fixture, and the locking member is provided at the front end of the main body fixture. By providing an engaging portion for engaging with the locking member inside the door locking member, it becomes difficult to infer the structure from the appearance, and therefore, it is difficult to break.
