Description

[Detailed Description of the Invention] The present invention relates to a control panel housing a control device, and particularly to a stopper structure for a door thereof.

The control panel has its opening side closed by a single or double door. These doors are usually rotatably supported on the main body by hinges. If the hinge is an external hinge or a refrigerator-type hinge, a stopper device is required to regulate the opening angle of the door.

In this type of conventional stopper device, the main body of the control panel and the door are connected by a link mechanism, and the opening angle of the door is regulated by the length of this link.
However, such a link mechanism stopper device is
It is structurally complex, and when opening and closing the door,
Because it is folded inside, the storage space inside the control panel is reduced.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stopper device for a control panel door of this type that is simple and can be incorporated outside the opening without using a conventional link mechanism.

Based on the above objective, the present invention forms an abutting piece at the end of the door, and makes this abutting piece abut against a stopper provided on the edge of the main body opening, thereby regulating the opening angle. .

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

First, FIGS. 1 and 2 show a general control panel 1. As shown in FIG. This control panel 1 is manufactured by sheet metal processing, and is provided with a pair of double doors (double doors) 5 that can be opened and closed at the front opening 3 of a box-shaped main body 2 by means of vertical vertical support shafts 4. . The support shafts 4 are attached to the main body 2 by support plates 6 at the upper and lower positions thereof, respectively, in a state of protruding toward the front side.

As shown in FIGS. 3 and 4 in addition to FIGS. 1 and 2, the stopper device 10 of the present invention has an abutment piece 11 attached to the end of the door 5 on the side of the support shaft 4.
The contact piece 11 is configured to correspond to a stopper 12 fixed to, for example, the upper opening edge of the main body 2. The contact piece 11 has an L-shape, for example, and is formed integrally with the door 5 by cutting out a part of the edge plate 14 formed on the back surface of the door 5, and the stopper 12 has a U-shape in cross section and is integral with the main body. It is fixed at the upper opening edge of 2 closer to the center of the opening 3 than the support shaft 4 by means of welding or the like. Note that the opening 3 of the main body 2 is bordered by a water return plate 13 formed around the opening 3. The water return plate 13 is formed by bending a plate material of the main body 2 into a U-shaped cross section. As a result,
The abutment piece 12 is assembled using the space (dead space) between the support shaft 4 and the water return plate 13.

Next, the operation will be explained. The pair of doors 5 close the opening 3 of the main body 2 while partially overlapping at their ends. When the user opens one of the doors 5, the stopper 12 of that door 5 rotates about the support shaft 4 and hits the inner surface of the stopper 12. Therefore, the opening angle of the door 5 is regulated by the contact between the contact piece 11 and the stopper 12, and the door 5 will not open any further.

In the above embodiment, the stopper 12 is provided only in the upper part, but the stopper 12 may be provided in the lower part, and the strength is sufficient if the stopper 12 is provided in one place either above or below. Also, this stopper 12 is the water return plate 1 of the main body 2.
It can also be formed from a part of 3.

According to the present invention, the contact piece is integrally formed as a part of the door, and only a simple stopper is added, so the structure is simple and it is easy to implement by sheet metal fabrication. Moreover, the stopper is built into the space between the spindle and the water return plate and is not exposed to the outside, so the appearance of the control panel will not be damaged.
