[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine having an inner door, and more particularly to a structure of an outlet door for opening and closing a product outlet formed at a lower portion of the inner door.

[0002]

2. Description of the Related Art In a conventional vending machine, an outer door is provided at a front portion of a body of a heat insulating structure in which a product storage room is formed, and a product outlet is provided at a lower front surface of the outer door. A product outlet is provided at a lower portion of the inner door which is disposed opposite to the outer door and opens and closes the front opening of the main body so as to correspond to the product outlet. As a result, commodities sliding down the commodity chute provided in the commodity storage room pass through the commodity carry-out port and are then carried out to the commodity take-out port.

[0003] In addition, this product outlet is described in Japanese Unexamined Patent Publication No. 2-8 / 1990.
No. 987, a plate-like exit door is provided with its upper end pivotally supported. Usually, this exit door closes the product exit and allows outside air to enter the product storage room. When the product is carried out, the product chute is pushed open against the product sliding down.

By the way, when the product exit door is formed in a flat plate shape, the center of gravity of the door is located vertically below the shaft, and when the position of the center of gravity is vertically below the shaft as described above, Since no force is generated in the carry-out door in a direction in which the carry-out door comes into contact with the front edge of the commodity carry-out port, the commodity carry-out door may be opened by cold or warm air circulating in the commodity storage room.

Conventionally, as shown in FIG. 5, a frame-shaped abutting portion 2 inclined rearward is projected from a front edge portion of the product carrying-out port 1, and the product carrying-out door 3 is provided on the abutting portion 2. To make the product exit door 3 tilt, so that the position of the center of gravity of the product exit door 3 is lower than the vertical lower portion of the shaft portion 3a.
I try to approach the side.

By shifting the position of the center of gravity toward the product outlet 5 in this manner, a force (moment) in the direction toward the product outlet 1 can be generated at the product outlet door 3, whereby the product can be transported. The exit door 3 can be brought into close contact with the product carry-out port 1, and the product carry-out door 3 can be prevented from being opened by cold or warm air circulating in the product storage room 6. In the figure, reference numeral 7 denotes a product receiving unit for receiving a product falling from the product exit 1,
Reference numeral 8 denotes a burglar plate supported above the product receiving portion 7, and reference numeral 9 denotes an inner door.

[0007]

In order to ensure that the product can be carried out when the product is carried out, the distance between the tip of the product exit door that is pushed open by the product and the lower end of the product exit is required. It is necessary to form a space between the product outlet and the product outlet having a width in the front-rear direction just enough to rotate the product outlet door upward to a position at which the product can pass reliably by a predetermined distance.

In order to form such a space,
The outer door must have a predetermined depth dimension. However, in the conventional vending machine as described above, since the product exit door is in contact with the contact portion 2, the end of the product exit door is Is closer to the outer door 4 by the depth dimension (d1) of the lower end of the contact portion 2 as shown in FIG.

For this reason, in order to secure the predetermined distance (L), it is necessary to rotate the product exit door 3 further upward by an amount that the tip of the product exit door 3 is closer to the outer door 4. The depth dimension (D1) of the outside door 4 also becomes large, and there is a problem that it is impossible to meet the market demand for a thinner vending machine.

[0010] It is an object of the present invention to provide a vending machine capable of reducing the depth of an outer door.

Can be moved toward the product outlet 5 by d2 from the vertical lower side of the shaft portion 11c. In this way, by shifting the center of gravity toward the product outlet 5, the product outlet door 11 is positioned in front of the product outlet 1. A force (moment) in the direction of contacting the edge can be generated.

By generating a force in the direction of abutting the front edge of the product exit 1 on the product exit door 11 as described above, the frame-shaped contact portion 2 (see FIG. 5) as in the prior art. Product exit door 1 without protruding the front edge of the product exit 1
1 can be brought into contact with the front edge of the product exit 1, so that the distance that the tip of the product exit door 11 approaches the outer door 4 depends on the thickness of the frame 1a of the product exit 1 as shown in FIG. Size (d
3) only.

Here, the thickness dimension (d3) of the frame portion 1a
Is smaller than the depth dimension (d1) of the lower end of the contact portion 2 protruding from the conventional product exit 1, so that the distance approaching the outer door 4 of the product exit door 11 is reduced by the difference. It will be. For this reason, the predetermined distance (L) can be secured without rotating the product carry-out door 3 so much upward, and the depth dimension (D2) of the outer door 4 is correspondingly increased as shown in FIG. Can also be reduced.

In the figure, reference numeral 12 denotes a stopper provided above the product receiving portion 7, and the central portion of the front wall 11a hits the stopper 12 so that the product exit door 11
Is restricted from rotating upward. by the way,
When the product exit door 11 rotates to the position where it hits the stopper 12 in this manner, the product exit 5 is closed at the lower part of the curved front wall 11a.

Accordingly, the front wall 11a is formed in a curved shape as described above, and the commodity carrying-out door 11 is made rotatable by the stopper 12 to a position where the front wall 11a closes the commodity taking-out port 5, so that the conventional apparatus can be used. Without providing a burglarproof plate 8 (see FIG. 5), it is possible to prevent the product outlet 11 from being illegally opened. Further, by not providing the antitheft plate 8 in this manner, it is possible to take out the product without being obstructed by the antitheft plate 8.

On the other hand, in the present embodiment, the product exit door 11 is made of a transparent resin. As described above, the anti-theft plate is not provided, and the product outlet door 11 is formed of a transparent resin in this manner, so that the product carried out of the product outlet 1 can be visually recognized. For example, even when a product is caught in the product exit 1, the product can be easily taken out.

Furthermore, by forming the front wall 11a of the commodity exit door 11 to be curved toward the commodity outlet 5, the commodity sliding down the commodity chute (not shown) can be moved along the curved inner wall surface of the front wall 11a. The product can be dropped while sliding, so that the product can be prevented from being jammed at the product exit 1.

On the other hand, in this embodiment, a number of vertical ribs 13 are formed on the inner wall surface of the front wall 11a as shown in FIG. The product exit door 1
1 does not cause scratches or the like.

Further, in this embodiment, a plurality of horizontal ribs 14 are formed at the lower part of the front outside of the front wall 11a as shown in FIG. 4, and the product outlet 5 is formed by these horizontal ribs 14. The product exit door 11 in the closing position or in the state where the product exit 1 is closed can be prevented from being illegally taken out by twisting in the lateral direction. Further, by providing the ribs 14 at the lower portion of the outer front surface of the front wall 11a, the ribs 14 serve as weights, so that the product exit door 11 is more reliably connected to the front edge of the product exit 1. Can come into contact with In addition,
