DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vending machine door fixing device.

[0002]

2. Description of the Related Art Vending machines are used for loading sales products.
Outer doors are frequently opened and closed, such as collecting and cleaning money. Further, since the required opening and closing angles are different each time, a door fixing device using a connecting rod connecting the vending machine and a guide device attached to the vending machine main body which can be fixed at an appropriate angle is required. When performing service work such as repair, it is necessary to fully open the door of the door fixing device. At this time, it is necessary to remove one end of the connecting rod on the sliding side of the main body from the guide device. At one end is unstable and hinders service work. It is sufficient to remove the rotating shaft of the connecting rod, but it is difficult to work because it has split pins and screws to prevent it from coming off. There is a demand for a fixing structure that allows the connecting rod to be easily removed without using tools or the like for daily maintenance.

Conventionally, as a door fixing device for a vending machine,
JP-A-4
The one described in JP-A-112295 is known.

A conventional vending machine door fixing device will be described below with reference to the drawings.

FIG. 8 is a perspective view of a door fixing device of a vending machine. The vending machine door fixing device includes a connecting rod 41 rotatably mounted in a hole 49 of an outer door reinforcing plate 44 on a bottom surface of an outer door 53 outside the vending machine, and a split pin 42 for preventing the vending machine from coming off.
And a guide groove 47 for sliding the connecting rod 41 and the connecting rod 4
Vending machine main body 54 having a fixing groove 48 for fixing
And a guide device 43 attached to the device.

The connecting rod 41 is inserted into the hole 49 of the outer door reinforcing plate 44 from below, penetrates the hole 51 of the upper reinforcing plate 50, and is rotatably held by a washer 52 and a detachment preventing split pin 42. As the outer door reinforcing plate 44 is opened, the connecting rod 41 rotates about the end 45 of the connecting rod 41 with the outer door reinforcing plate 44, and the sliding portion 46 of the connecting rod 41 is pulled to guide the guide device 43. The groove 47 is slid and the fixing groove 48a
48c, the outer door 44 is fixed at a required angle.

FIG. 9 is a vertical sectional view showing the vicinity of an outer door reinforcing plate of a connecting rod of a conventional door fixing device. In FIG. 9, detachment is prevented by passing a split pin 42 through a through hole 53 at an end 45 of a connecting rod 41.

[0008]

However, in the above-mentioned conventional door fixing device, the operation of the connecting rod 41 of the door fixing device does not hinder the operation. In many cases, the door 44 is fully opened, and when the outer door 44 is fully opened, it is necessary to remove the split pins 42 and screws, which takes time.

[0009] In the summer sunshine or in the severe winter, the outer door 4
If the work is performed for a long time with the valve 4 fully opened, the inside temperature is adversely affected. In addition, since opening the door for a long time leads to theft of the sales proceeds, the service work by fully opening the outer door 44 is required to be prompt, but the presence of fixing tools such as split pins reduces the working time. It was against the flow.

When removing the connecting rod 41, the split pin 4
No. 2 was not easily deformed, and it was difficult to reuse the split pin 42 once deformed.

SUMMARY OF THE INVENTION The present invention has been made to solve the conventional problems, and in addition to being able to attach and detach the connecting rod of the door fixing device in a short time, to reduce the number of parts, etc., to improve the productivity and serviceability of the vending machine. It is an object of the present invention to provide a door fixing device.

[0012]

In order to solve the above problems, a door fixing device for connecting an outer door of a vending machine and a main body of the vending machine has a conventional guide device and a U-shaped bending process on a rotating side. It consists of a connecting rod. This allows
