[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door locking device for a vending machine.

[0002]

2. Description of the Related Art At present, a vending machine has a single door, and various proposals for a locking device have been made (for example, Japanese Patent Application Laid-Open No. 7-145555).

Hereinafter, a conventional door locking device for a vending machine will be described with reference to the drawings. FIG. 5 is an external perspective view of a conventional door locking device of a vending machine, and FIG. 6 is a partial perspective view of the door locking device in which a picture of a door body is omitted.

[0005] In FIGS. 5 and 6, 1 is a main body, 2 is a door, and is fixed to the main body 1 by a hinge 3. Body 1
A claw 4 having an upward convex portion is fixed to the inner side wall. A slide bar 6 having a square hole 5 to be engaged with the claw 4 and capable of sliding up and down is attached to the inside of the door 2.
A handle 7 is attached to the front of the door 2, and a handle body 8 is embedded in the door 2. The rotation of the key 9 causes the handle 7 to come forward from the handle body 8 and be gripped by hand. The pin 10 is displaced from the handle rotation axis and is at a position opposite to the handle 7. The pin 10 rotates in conjunction with the handle 7, but since the pin 10 is at a position symmetrical with respect to the rotation axis with respect to the handle 7, when the handle 7 is rotated in the downward direction, the pin 10 moves up. A bracket 11 having a horizontally long hole is fixed to the slide bar 6, and the pin 10 penetrates the long hole of the bracket 11, and slides in the long hole according to the rotation of the pin 10. I do.

[0005] The operation of the door locking device of the vending machine configured as described above will be described below.

When the door 2 is opened, the handle 9 comes out of the handle body 8 by rotating the key 9. By rotating the handle 7 downward, the pin 10 interlocked with the handle 7 is raised, thereby
Lifts the bracket 11 and the slide bar 6 while sliding in the long hole of the bracket 11. When the door 2 is closed, the projection of the claw 4 is caught on the upper part of the square hole 5 of the slide bar 6, so that the door 2 is not opened. When the slide bar 6 is lifted, the claw 4 comes off from the square hole 5, and when the door 2 is pulled in this state, the door 2 opens.

On the contrary, when closing the door 2, the handle 7
When the handle 7 is returned to the horizontal position after the door 2 is pushed and closed while the door 2 is lowered, the pin 10 is lowered, whereby the slide bar 6 is also lowered and the square hole 5 of the slide bar 6 is caught by the claw 4 so that the door 2 cannot be opened. Then, when the handle 7 is pushed in, the locking of the door 2 is completed.

[0008]

However, in the above-mentioned conventional construction, since the slide bar 6 is connected to the handle 7 and the key 9, in a vending machine having a plurality of doors 2, a slide without a key portion is required. Since the bar 6 cannot be attached, a locking device cannot be configured. Further, in the above-described conventional configuration, when the door 2 is lifted, the square hole 5 and the claw 4 are disengaged from the door 2 due to the relationship between the claw 4 and the square hole 5 of the slide bar 6. 2 had to be opened.

The present invention solves the above-mentioned conventional problems. In a vending machine having a plurality of doors, a door locking device is constituted even for a door without a key, and the door is lifted. Theft is prevented.

Further, in the above-mentioned conventional construction, when closing the door, the handle 7 is once lowered and the door 2 is kept as it is.
Must be closed, which is inconvenient when one hand is closed, and if the handle 7 is not raised enough, the position of the square hole 5 is low and the nail 4 does not enter the square hole 5 and slides. In the worst case, the nail 4 may collide with the bar 6 and destroy parts.

The present invention solves the above-mentioned conventional problems, and eliminates the operation of once lowering the handle to prevent a collision between parts.
