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

BACKGROUND OF THE INVENTION In recent years, vending machines have been designed to emphasize the product image by taking up a large space in the product display section and by minimizing the vertical dimensions of the selection buttons.

An example of the above-mentioned conventional vending machine door locking device will be described below with reference to the drawings.

6 to 9 show a locking device for a vending machine door. The configuration of this conventional example will be explained below with reference to FIGS. 6 to 9.

In the figure, 1 is the main body of a vending machine, and a door 2 is provided on the front side of the main body. The section 2 is formed with a product display room 3, a coin slot, and a coin return slot 6. Further, a product selection switch 6 is provided between the product display rooms 3, and a product take-out lower is provided below. 8 is main body 1
This is a handle provided on the opposite side of the door 2 which is pivotally supported at the top and bottom by a hinge 9. This hand/L/8 has 1 locking hole at the bottom.
0, and its upper end is pivotally supported on the door 2 by a shaft 11.

Reference numeral 12 denotes a key portion, on which a rotating plate 14 that is rotated by a key 13 is attached. A locking piece 15 includes a locking stopper 16 that retracts from the locking hole 1o of the hand/L/8, and an abbreviated stop plate 17 connected to the locking stopper 16. The locking stopper 16 is attached to the door 2 by passing through a guide piece 19 provided with a guide hole 18 attached to the back surface of the door 2. In addition, the locking plate 1 has a vertical groove 2o formed therein to form a screw 2.
1 so that it can slide up and down. Furthermore, an engagement hole 17' extending perpendicularly to the moving direction of the engagement piece 16 is formed in the engagement plate 17, into which an engagement pin 14' protruding from the rotating plate 14 is inserted. A 22-piece connecting plate A is a flat plate rotatably attached to the handle 8 on the lower side and a connecting plate B23 on the upper side with a pin. One end of the connecting plate B23 is pivotally supported by a holding pin 25 welded to a holding plate 24 fixed to the door 2 with screws. It also has a long hole at its upper end and is connected to a connecting plate C27 via a connecting pin 26. The connecting plate C27 is located between the retaining plate A29 of the locking piece and the retaining plate B30 of the locking piece, which are attached with screws to the top and bottom of the square hole 28 provided in the door 2, and one end is connected to the retaining plate A29 and the retaining plate B30. The other end is rotatably attached to the connecting plate D31 with a pin. 32 is a locking piece, and a nail-shaped flat plate is fixed with a pin between the upper and lower plates, and the holding plate A29 is
It is rotatably mounted between N30 with a pin and is also rotatably connected to the connecting plate D31 with a pin. 33
is an engagement piece attached to the opposite side of the door 2 of the main body 1 with a screw, and has a square hole 34 in the center.

The operation of the door locking device configured as described above will be explained. The state where N2 covers and locks the main body 1 is the 7th
As shown by the solid line in the figure, when the locking stopper 16 of the locking piece 16 is in the locking hole 10, the handle 8 cannot be gripped, so the door 2 cannot be opened. Then, even if the locking piece 32 is inserted into the square hole 34 of the engaging piece 33 and an attempt is made to open the door 2, the door 2 will not open.

When opening the door 2, when the key 13 is inserted into the key part 12 and rotated, the rotary plate 14 is rotated. This rotation causes the engagement pin 14' to rotate, but the engagement hole 17' causes the engagement plate 1 to rotate.
7 moves downward and locks the locking stopper 1 from the locking hole 1°.
6 descends and comes out of the hole. By this, spring 3
At step 5, the handle 8 pops out in front of the door 2. Next, when the user holds this hand A/8 and lifts it forward and upward, the locking piece 32 is moved from the plurality of connecting plates A to the DK and to the rear left side. As a result, the @lock piece 32 moves through the square hole 34 of the engagement piece 33 and is removed from the engagement piece 33.

Next, when the hand/I/8 is pulled toward the front (to the left in FIG. 2), the door 2 opens from the main body 1. Next, when closing and locking the door 2, after aligning the door 2 with the main body 1, push down the hand /l/8 (move to the right side in Figure 2). Then, the locking piece 32 moves to the front right side and enters the square hole 34 of the engagement piece 33, thereby preventing the door 2 from opening.

Problems to be Solved by the Invention However, in the above configuration, the locking stopper 1
6 or the handle 8 is deformed and cut to form the hand IV.
8', the connecting plates A to D move regardless of the positions of the engaging pin 14' of the key part 12 and the locking plate 17, and the locking piece 32 moves from the engaging piece 33. When it comes off, N2 opens from main unit 1 and is stolen. Further, it cannot be used when there is no space in the vertical direction of the section 2 and the hand JVB and the key section 12 are provided laterally. In addition, when the locking piece 32 locks, it is impossible to maintain a uniform gap between the door 2 and the main body 1 in the vertical direction because it locks at one place, so the position of the square hole 34 of the engaging piece 33 must be adjusted in the front-rear direction. It had the disadvantage of being indispensable.

In view of the above problems, the present invention prevents the locking piece from moving even if the locking stopper or handle is deformed or cut, and also reduces space when the handle and key are provided in the lateral direction of the door. The present invention provides a door locking device that maintains a constant gap between the door and the main body.

Means for Solving the Problems - In order to solve the above problems, the door locking device of the present invention has a handle that extends in the horizontal direction with the end opposite to the shaft supported, and a locking piece that is parallel to the moving direction of the locking piece. A guide pin provided in the direction, a connecting plate that locks when the guide pin protrudes and retracts, and a connecting plate that extends in the vertical direction and is connected through a plurality of connecting plates and engages with a plurality of locking plates formed on the main body. It is equipped with a vertically elongated hole provided in the existing locking piece.

Operation According to the present invention, even if the locking stopper or handle is deformed or cut, the handle will not move forward because the guide pin provided on the locking piece locks the connecting plate. In addition, by converting the force of moving the horizontally extending handle back and forth into the force of vertically moving the locking piece extending vertically through the connecting plate, it can also be used for doors that do not have space in the vertical direction. Moreover, by engaging the locking piece with a plurality of locking plates, the gap can be kept uniform.
