DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supporting an outer door of a vending machine for preventing the outer door from tilting away from the hinge.

[0002]

2. Description of the Related Art FIG. 2A is an external view of a vending machine,
(B) is a cross-sectional view of the vending machine, and FIG. 3 is a configuration diagram of a conventional support bracket. In FIG. 2, reference numeral 1 denotes a main body cabinet for storing components of a vending machine, 1a denotes a base forming the bottom wall of the main body cabinet 1, 1b denotes a square hole formed in the base 1a, and 1c denotes a base 1a. Perforated screw holes, 2 is an outer door, 3 is an inner door, 4 is a product storage shelf, 5 is a cooling unit that cools and circulates refrigerant when cooling and preserving products, 6 is a product outlet, and 7 is a product input. The mouth 8 is a roller attached to the lower part of the outer door 2 on the side opposite to the hinge, and 9 is a support for the roller 8. The vending machine of the above configuration shows a canned beverage vending machine,
A cylindrical can (hereinafter referred to as “commodity”) in which a beverage is enclosed is introduced from a commodity introduction port 7 at an upper portion of the main body cabinet 1 and is stored and stored in a product storage shelf 4. In the room in which the product storage shelves 4 provided for different products are stored, the interior of the main body cabinet 1 is partitioned into several rooms by a heat insulating material, and a cooling and warming room is formed in which an inner door 3 made of a heat insulating material is arranged on the front surface. When the room is to be kept cool, cooling is performed using the refrigerant circulated from the cooling unit 5, and when the room is kept warm, hot air from the heater is circulated. The commodities are stored after being cooled or heated in those rooms, and are discharged to the commodities outlet 7 at the time of sale. Here, although not shown, the outer door 2 is a heavy object provided with an exhibition room for product samples, a cash processing device for managing deposits and withdrawals at the time of sale, and other control devices. For this reason, simply attaching the hinge to the main body cabinet 1 cannot prevent the outer door 2 from falling toward the opposite hinge side and inclining so-called the door. Therefore, a roller 8 is attached to a lower portion of the outer door 2 and the roller 8 is received by a support fitting 9 attached to a protruding portion of the base 1a of the main body cabinet 1 to prevent the outer door 2 from tilting to the opposite hinge side.

[0003] As shown in detail in Fig. 3, the support fitting 9 has a downward L-bent portion 9c at a front end, a screw insertion hole 9d at a rear end, and a rearwardly rising slope surface at an intermediate portion. It has a rampway 9a consisting of a horizontal plane, and inserts the L-bend 9c at the front end into a square hole (locking hole) 1b formed in the base 1a, and then inserts a tapping screw 9e into an insertion hole 9d at the rear end. It is screwed into the screw hole 1c of the base 1a.

In this configuration, during the process of closing the outer door 2, first, the roller 6 is guided to ride on the slope of the rampway 9a and to be gradually lifted up on the slope.
By being supported on the horizontal plane of a, the door descent is corrected.

[0005]

By the way, in the conventional configuration, the mounting of the support bracket to the base is screwed.
It takes time to assemble. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vending machine outer door support device that eliminates screwing.

[0006]

According to the first aspect of the present invention, a rotatably supported roller is provided at a lower portion on the side opposite to the hinge side of the outer door hinged to the main body cabinet, and the roller is guided or supported. In the middle part, a rampway consisting of an upwardly inclined surface facing rearward and a horizontal plane following it, a downward bent part at one end of the front and rear ends, and a horizontal part at the other end extend in the opposite direction to the middle part. An outer door for a vending machine, comprising a support fitting provided with an L-bend, and a locking hole for inserting the bent part of the support and the L-bend are provided in a base of a main body cabinet. Support device.

[0007] With the above configuration, the support bracket can be mounted simply by inserting the front and rear bent portions into the base body. According to the second aspect of the present invention, in the outer door support device according to the first aspect, the support fitting has a downwardly bent portion at a front end and an L-shaped bent portion at a rear end. Supporting device.

[0008] This configuration prevents the rear end of the support fitting from rising when the roller rides on the slope of the rampway.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a configuration diagram of a main part of an embodiment of the present invention. In FIG. 1, members denoted by the same reference numerals as those of the conventional example have approximately the same functions, and therefore description thereof will be omitted. The vending machine to which the present invention is applied is the same as that shown in FIGS. 2 and 3 described in the section of the prior art, so that the description thereof will be omitted. In FIG. 1, 1a is a base forming the bottom wall of the main body cabinet 1, 1b is a square hole as a locking hole formed in the base 1a, 9
Numeral 0 denotes a support for the roller attached to the lower surface of the outer door, 90
a is a rampway formed in the middle part of the support fitting 90 and has a rearwardly rising surface and a horizontal plane following it. 90b is an L in which the horizontal part of the rear end of the support fitting 90 extends in the direction opposite to the middle part. A bent portion 90 c indicates a downward bent portion formed at the front end of the support fitting 90. In FIG. 1, a support fitting 90 includes a rampway 90 a having a rearward upward slope surface and a horizontal surface following the middle portion,
The front end has a downward bent portion 90c, and the rear end has an L bent portion 90b whose horizontal portion extends in the opposite direction to the middle portion.
By inserting bent portions 90b and 90c at the front and rear ends into square holes 1b as locking holes formed in the base 1a, the base 1a can be attached to the base 1a without screwing. When the outer door 2 (see FIG. 2) is closed, the roller 8 mounted on the lower surface of the outer door 2 on the side opposite to the hinge rides on the horizontal surface of the ramp way 90a of the support fitting 90 and applies a downward load to the support fitting 90. Therefore, the mounting of the support fitting 90 does not come off.

Further, by providing the L bent portion 90b at the rear end of the support fitting 90, when the roller rides on the slope at the tip of the rampway 90a in the process of closing the outer door 2,
The rear end of the support fitting 90 does not unexpectedly jump up and come off.

[0011]

According to the present invention, the mounting of the support bracket does not require tools and screws, thereby reducing the number of parts and reducing the number of mounting steps. Further, when the roller rides on the leading end of the rampway, the L bent portion at the rear end of the support bracket is hooked on the edge of the locking hole of the base to prevent the rear end from being flipped up.
