Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a door device for a vending machine.

BACKGROUND ART In recent years, in order to improve workability during service of vending machines, door devices have been proposed that facilitate door opening operations.

A conventional door device for a vending machine will be described below. 3 to 6 show conventional door devices for vending machines. In the figure, reference numeral 1 denotes the main body of the vending machine, which is formed by a heat insulating wall, and a storage chamber 2 inside thereof is provided with a serpentine column 3. This column 3 is provided across the width of the storage chamber 2. A door 4 with a heat-insulating structure is provided on the front surface of the main body 1, and a main door 5 is provided on the front surface with a curing device, a selection button, a product display device, a sales product outlet, etc. (not shown). ing. A cooler 6, a heater 7, a blower 8, etc. are provided at the bottom of the column 3 of the storage chamber 2, and a compressor 9, a condenser 10, etc. are provided at the bottom of the main body 1. Further, a substantially U-shaped cover 11 for fixing the blower 8 and a top plate 12 are attached to the cooler 6 so as to form a box. Further, 13 is a chute that guides the product discharged from the column 3 to the outlet. A fixed plate 14 having a hollow part formed in the front part is disposed on one side of the front part of the main body 12, and a movable plate 15 having a substantially L-shape and having hollow parts formed in the front and rear is disposed on the fixed plate 14. There is. The hollow portions of the front parts of the fixed plate 14 and the movable plate 15 are pivotally supported by pins 16a, and the fixed plate 14 is fixed to the main body 1 by the mounting screws 17a and the movable plate 15 is fixed to the main body 1 by the mounting screws 17b. There is. A holding plate 18 having a hollow portion at the front and fixed to one side of the door 4 is positioned above the movable plate 15, and the holding plate 18 is connected to the hollow portion at the rear of the movable plate 15.
They are rotatably supported by a pin 16b with their hollow parts aligned.

The operation of the vending machine door device configured as above will be described below. When replenishing and storing products in the column 3, the door 4 is opened after the main door 5 is opened. At this time, as shown in Fig. 4, the door 4 is located on the front side of the column 3 in dimension A, and the opening area cannot be made very large, so it is not possible to take out the column 3 in this state. It was hot. Therefore, the above column 3
In the case of service for removing etc., a pin 16 and a mounting screw 17b for fixing the movable plate 15 to the main body 1 are used.
Remove the door 4 with a screwdriver or the like and move the door 4 from the front of the column 3 to the position of dimension B as shown in FIG.
is made larger to make it easier to get out column 3 etc.

Problems to be Solved by the Invention However, in the conventional example described above, it was necessary to remove the mounting screws 17b of the movable plate 15 from the lateral direction using a tool or the like, which was difficult. Also, pin 16
There was a risk of losing it because it was attached and detached.

The present invention solves the above-mentioned conventional problems, and aims to provide a door device for a vending machine that can reduce the effort and difficulty of servicing and can be easily performed.

Means for Solving the Problem In order to achieve this object, the vending machine door device of the present invention has a fixing plate in the main body that is approximately L-shaped and has a hollow part formed in the front and back, and has the same structure as the fixing plate. A shaped movable plate and a holding plate attached to the door with a hollow part formed at one end, the movable plate is positioned on the fixed plate,
A holding plate is positioned on the movable plate, and a pin is inserted into the hollow part at the front of the fixed plate and the movable plate to rotatably support the door, and the hollow part at the rear of the fixed plate and the movable plate and the holding plate are inserted. The L-shaped pin is inserted gently into the hollow part of the plate to rotatably support the door and has an L-shaped upper end, and this L-shaped pin is inserted only into the hollow part at the rear of the fixed plate and the movable plate. The L-shaped pin has a flange provided at a position to lock the upper end of the L-shaped pin in the closed state.

With this configuration, when opening the door during service, pull the L-shaped pin upward to remove it from the hollow part of the fixing plate, lock the L-shaped pin to the flange of the retaining plate, and then is inserted into the hollow part of the movable plate and the holding plate, and the door is supported by an L-shaped pin so that it can be opened and closed freely, thereby increasing the spatial angle between the door and the main body.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show a door device for a vending machine according to an embodiment of the present invention. In addition,
Components that are the same as those in the prior art will be given the same numbers and detailed explanations will be omitted. In the figure, reference numeral 19 denotes a fixed plate having a substantially L-shape and having hollow parts at the front and rear, which is fixed to the main body 1, and a movable plate 15 having the same shape as the fixed plate 19 is pivotally supported on the upper part by a pin 16a. There is. A door 4 is provided in the upper part of the rear hollow part of the movable plate 15.
The rear hollow part of the fixing plate 19 is located below the hollow part of the holding plate 20 which is fixed to one side, and each is pivotally supported by an L-shaped pin 21 with the respective hollow parts aligned. An inclined flange a is provided on the upper side of the holding plate 20 so that one end of the L-shaped pin 21 can be locked therein. The hinge 23 rotatably supports the main door 5 on one side of the main body 1, and is provided on the same side as the fixed plate 19.

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

First, pull the L-shaped pin 21 upward by hand to remove it from the hollow part (shaft support) of the fixing plate 19, and then remove it from the holding plate 20.
The L-shaped pin 21 is fixed to the movable plate 15 and the retaining plate 20 to the door 4 by locking the upper end to the flange a.
The door 4 is in a state where it is pivotally supported, and the door 4 is in a state where it can rotate around the pin 16a located on the front side.

As described above, according to this embodiment, approximately L is provided in the main body 1.
A fixed plate 19 having a shape of a letter with hollow parts formed in the front and rear is provided, a movable plate 15 having the same shape as the fixed plate 19, and a retaining plate 19 attached to the door 4 and having a hollow part formed at one end, The movable plate 15 is placed on the fixed plate 19.
By positioning the holding plate 20 on the movable plate 15 and providing the pin 21 that is rotatably supported by aligning the respective hollow parts, the pin 21 on the door 4 side can be held with one hand. With a simple operation, the spatial angle between the door 4 and the main body 1 can be increased, improving workability during service and eliminating the need for tools such as screwdrivers.

Effects of the Invention As described above, the present invention includes a fixed plate that is approximately L-shaped and has hollow parts formed in the front and rear of the main body, a movable plate that has the same shape as the fixed plate, and a movable plate that is attached to the door and has one end. A holding plate having a hollow portion formed therein is rotatably supported by positioning a movable plate on top of the fixed plate, positioning a holding plate on top of the movable plate, and aligning the respective hollow portions. By providing a pin, you can increase the spatial angle between the door and the main body by simply operating the pin on the door side with one hand, improving work efficiency during service and eliminating the need for tools such as screwdrivers. It can be done.
