Abstract

PURPOSE:To provide the rigid external door structure of the automatic vending machine which can secure the standing state of a door that is high in rigidity and stable for a long period by additionally providing a simple member in the door. CONSTITUTION:The external door 2 of the automatic vending machine which has one end hinged and coupled with the front surface of a cabinet has an opening window 2a for fitting a large-sized electric lighting plate formed in the front surface of its door main body 2, and a long-sized reinforcing member 2h made of a channel-shaped steel plate machined in a sectionally U shape along the internal wall surface of a left longitudinal frame 2 positioned on the hinge side is integrally welded and joined with a door frame 2c which projects backward from the peripheral edge of a door main body. Consequently, the rigidity to the bending of the external door is increased and the door is prevented from deflecting and deforming while fitted to the cabinet, thereby maintaining the standing state of the door which is stable for a long period.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer door structure for a vending machine.

[0002]

2. Description of the Related Art First, FIG. 2 shows a cabinet structure of a vending machine. In the figure, 1 is a box-shaped cabinet main body that stores product storage shelves and the like, 2 is an outer door provided on the front surface of the cabinet main body 1, and the outer door 2 is a cabinet whose one end (left side) is an opening and closing fulcrum. It is attached to the main body 1 via hinge hinges 3 so as to be openable and closable. The outer door 2 is made by sheet metal working of a thin steel plate, and a display room defined inside the door (a sample product is displayed).
A window is opened on the front surface of the outer door 2 so as to cover the front surface thereof, and a lighting plate 4 is fitted therein. Note that 5 is a product outlet. Further, although not shown, a middle door is attached to the rear surface side of the outer door 2, and this door plate is equipped with various devices such as a coin mechanism, a collection box, and a control panel.

[0003]

By the way, the outer door of the above-mentioned vending machine has a relatively high rigidity against bending etc. when the ratio of the illumination plate 4 to the entire area of the door is small. As shown, when the illumination plate 4 is large, the area of the window opened on the front surface of the outer door 2 is large, so that the required rigidity cannot be ensured with the conventional structure, and for this reason, the cabinet In a state where the outer door 2 is attached to the main body 1 via the hinge metal fitting 3 in a cantilever manner, the outer door 2 itself is bent due to its own weight, and the original shape cannot be maintained. During use, the overall shape of the outer door 2 remains slightly distorted. Moreover, if the outer door itself is bent or deformed as described above, the door is in a bad standing state, and the door cannot be opened / closed or locked with the cabinet 1 smoothly. It causes a problem that it does not fit well in the door.

The present invention has been made in view of the above points, and by additionally providing a simple member inside the door, the above-mentioned problems are solved and high rigidity and a stable standing state of the door for a long period of time are secured. An object is to provide a robust outer door structure for a vending machine that is made possible.

[0005]

In order to achieve the above object, in the outer door structure of the present invention, a door frame extending rearward from the peripheral edge of the door main body is provided with at least one of the left and right vertical frames. A long reinforcing member having a closed cross-sectional shape is provided integrally with the frame. Further, in the above-mentioned outer door structure, it is preferable that the reinforcing member is provided on the inner wall surface side along with the door vertical frame on the hinge side, and the reinforcing member can be implemented by a channel-shaped steel plate having a U-shaped cross section. .

[0006]

With the above structure, the rigidity of the outer door against bending is increased. Therefore, even in an outer door equipped with a large-sized lighting plate that occupies a large proportion of the area of the outer door, the door can be prevented from being bent or deformed due to its own weight or external force, and a stable opening / closing operation of the door can be ensured.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS.
It will be described based on. In FIG. 1, (a) is a cross-sectional view of the outer door, (b) is a rear view, and (c) is a vertical cross-sectional view. The outer door 2 has a large illumination plate fitted to the front surface. A door body 2b having a sheet metal structure with an opening window 2a for inserting the door body 2b, and the door body 2b.
The door frame 2c that is welded to the periphery of the and protrudes rearward (this door frame serves as a mounting frame for the middle door, and also fits into the cabinet when the outer door is closed so that a gap between the outer door and the cabinet is present. The door frame 2c has a left vertical frame 2d located on the hinge side of the door when viewed from the front and a right vertical frame 2e on the opposite side.
The upper and lower frames 2f and 2g are assembled from the left and right frames and the upper and lower four side frames. A reinforcing member 2h is integrally incorporated and welded to the door frame 2c along the entire length of the inner wall surface of the left vertical frame 2d. This reinforcement member 2h
Is a channel-shaped steel plate with a U-shaped cross section,
As shown, a hollow beam having a closed cross-section is formed between the door frame and the left vertical frame 2d in the assembled state.

By integrally incorporating the reinforcing member 2h having a closed cross-section into the outer door 2 as described above, the bending rigidity of the outer door is increased, and the outer door 2 is attached to the cabinet body 1 by the hinge fitting 3 as shown in FIG. Even if a bending force is applied from the outside or the outer door 2 is repeatedly opened and closed while it is attached in a cantilevered manner via the outer door, the outer door hardly bends or deforms, and is a good door for a long time. It has been confirmed from the results of the actual machine test that it is possible to maintain the erected state.

[0009]

As described above, according to the structure of the present invention, the rigidity of the outer door is significantly increased as compared with the conventional door structure.
In particular, when the reinforcing member has a closed cross-sectional shape, a large bending rigidity can be obtained. Therefore, even if a window occupying a large area is opened on the front surface of the door in order to mount a large-sized lighting board, the outer door itself hardly bends or deforms, and the door is always stable even after long-term use. In addition to being able to maintain the erected state of the door to ensure smooth opening and closing of the door, it is also very useful for mischief trying to forcefully open the outer door because it is more robust.
