DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inner door provided on the front side of a refrigerator serving as an insulating room in a vending machine for selling goods such as canned beverages.

[0002]

2. Description of the Related Art A vending machine for selling products such as canned beverages as cold products or hot products is provided with a heat-insulating inner door having a square-hole-shaped product passage at the front inside the refrigerator.
Further, a flapper that opens and closes freely is provided in the product passage. The product passage is formed by fixing a rectangular frame having a flange on one side to the inner door with a small screw in a square hole formed in the inner door body. Also, the flapper is formed by forming a groove in the frame body for supporting the support shaft of the flapper, and closing an entrance of the groove with a holding metal fixed by a small screw to prevent the support shaft from coming off. It is freely supported.

[0003]

In the conventional inner door, however, the frame must be screwed in order to form a product passage, which requires a very complicated operation.

[0004] The present invention eliminates the drawbacks of the conventional device,
It is an object of the present invention to provide an inner door capable of forming a product passage with extremely simple work.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a door for opening and closing a front surface of a refrigerator, wherein a square hole formed in the inner door body is provided on one side with an inner door body. The product passage is formed by fitting a rectangular frame having a flange abutting on the surface of the product passage, and the inner door of a vending machine in which a flapper is suspended from the product passage. In addition to providing a protruding flexible claw, the inner door main body is provided with a receiving portion that locks the claw when the frame is fitted into the inner door main body and prevents the frame from coming off. And

[0006]

According to the present invention configured as described above,
By pushing a square frame-shaped frame having a flange abutting on the surface of the inner door body into the square hole of the inner door and fitting the same, the claw formed on the frame is opened and prevented from falling out. A product passage is formed only by pushing into the square hole of the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In the figure, 1 is an inner door, 2 is two thin iron plates 3
Is an inner door body formed by a heat insulating wall sandwiching the heat insulating material 4. The inner door body 2 is provided with a square hole of an appropriate size, and the periphery of the square hole is formed by removing the heat insulating material to expose the thin iron plate, and a part of the thin iron plate 3, in this case, three positions on the left, right, and upper portions. The receiving portion 5 is formed at the bottom. Reference numeral 6 denotes a rectangular frame having a substantially horizontal Z-shaped cross section and an outward flange 6a on the front surface.
The inner door body 2 is fitted into a square hole, and a product passage 7 is formed inside the square hole. The frame 6 is provided with a flexible claw 8 corresponding to the receiving portion 5 by making a cut in a part of the body facing the inner surface of the square hole and bending it outward. Further, rib-shaped protrusions 9 and flexible tongues 10 corresponding to the protrusions 9 are provided at both left and right end portions of the upper side to form an alligator-shaped shaft hole 11 having a narrow entrance 11a. You. Numeral 12 denotes a flapper installed in the product passage 7, and a support shaft 13 is provided at upper right and left ends thereof in correspondence with the shaft hole 11.

In the above-described configuration, the frame 6 is attached to the inner door main body 2.
When the frame body 6 is mounted on the frame 6, the claw 8 is once bent inward and is pushed into the square hole, and the claw 8 is turned outward at a position where the flange 6a is completely pushed in contact with the front surface of the inner door body 2. Then, the frame 6 is returned to the receiving portion 5 and fixed in the mounted state.
After the frame is mounted, a soft heat insulating material 4a is packed around the square hole. Next, when attaching the flapper 12, the flapper 1
Reference numeral 2 designates a support shaft 13 which is applied to an inlet 11a of the shaft hole 11;
When pushed toward 1, the tongue piece 10 bends and the entrance is once widened, and the support shaft 13 is inserted into the shaft hole 11, supported rotatably and stopped by the tongue piece 10 that has returned to its original position. As a result, the flapper 12 is rotatable.
And is attached to the product passage 7 so as to be openable and closable. In this manner, the frame 6 is easily mounted simply by being pushed into the square hole, and is fixed at the mounting position without using small screws or the like. Similarly, the flapper 12 is easily and rotatably attached to the frame 6 simply by pushing the support shaft 13 into the shaft hole 11.

[0009]

According to the present invention, as described above, according to the present invention, a door for opening and closing the front surface of the inside of a refrigerator, and a square hole formed in the inner door body, and one side of the door, which contacts the surface of the inner door body. A rectangular frame-shaped frame having a flange in contact therewith is fitted with a product passage, and the inner door of a vending machine in which a flapper is suspended from the product passage. With the provision of a claw, the receiving portion that locks the claw when the frame body is fitted into the inner door body and prevents the frame body from coming off is provided on the inner door body, By simply pushing the frame in, it is fixed to the inner door main body and a product passage is formed. Therefore, the product passage in the inner door is easily formed by a very simple operation.
