Description

[Detailed Description of the Invention] The present invention relates to an operation desk, and particularly to an operation panel thereof.

Conventionally, operation desks (control consoles) have been used in monitoring and control devices for plants, water treatment, power transmission and distribution, and other power equipment, for example. An operation panel (switch panel) having a large number of switches is attached to the operation desk, and one end thereof is hinged to the upper surface of the operation desk so that it can be opened and closed. That is, as shown in FIGS. 1 to 3, the operation panel 2 on the operation desk 1 has a rectangular shape that has a large number of key switches 3 and is attached to a hinge 4 so that it can be opened and closed from the top surface of the operation desk 1. It consists of a box-shaped body. However, since the operation panel 2 is processed such as tilting the top surface and welding the four corners, various distortions occur. When it is connected to the operation desk 1 with the hinge 4, it often cannot be placed stably on the tabletop plate 1a and wobbles occur due to twisting in the direction or distortion due to minute differences in dimensions. Therefore, the work to correct such distortions and the like is complicated.

Furthermore, the entire operation panel 2 is
a', front plate 2b', and back plate 2c' to form a box-like body, it is heavy and therefore heavy when opened and closed from the operation desk 1, and maintenance and inspection of the operation panel 2 itself is also easy. It wasn't.

In view of these circumstances, the present invention aims to improve the operation panel of such conventional operation desks, and aims to simplify the production and installation of the operation panel, as well as improve ease of handling and reduce economic costs. To provide an operation desk equipped with an operation panel that can perform the following operations.

Hereinafter, the present invention will be explained based on the illustrated embodiments. FIG. 4 shows the entire operation panel 2, FIG. 5 is a sectional view taken along line B-B in FIG. 4, and FIG.
It is a sectional view taken along line C. The operation panel 2 is a square plate 2a.
Two side ends 2b in the opposing longitudinal direction of
C is a cap 5 made of lightweight material such as synthetic resin.
are fitted into each other.

The cap 5 has a recess 5a into which the side end 2c can be fitted.
In addition, leg portions 5b are provided on the upper surface of the operation desk 1 to hold the operation panel 2 horizontally or in a required inclined state. A rib 5c that comes into contact with the back surface of the operation panel 2 is formed in the recess 5a if necessary. The leg portion 5b is formed by extending one side of the cap 5 itself, and is attached to the tabletop plate 1 of the operation desk 1.
It may be in full or partial contact with a. When the legs that partially touch are provided, there is an advantage that a ventilation hole can be formed to dissipate the heat generated by the operation desk 1 or the operation panel 2 itself. Further, the cap 5 may be fixed to the side end 2c with screws or the like. Thus, the long side end 2b of the operation panel 2 is connected via the shaft 6 to hinges 7, 7 protruding from the tabletop plate 1a, together with a retaining ring 6a. The shaft 6 is supported by bearings 8, 8, and the bearings 8, 8 are fixed within a bent portion formed at one side end 2b of the operation panel 2. 9 connects the bearing 8 to the operation panel 2
Fasteners such as blind rivets are used to fix the hinge 7 and the hinge 7 to the tabletop plate 1a, respectively.

Although it has been described that the cap 5 is made of synthetic resin as the lightweight member, it is not limited to synthetic resin, and any material that is lighter than the material of the operation panel 2 such as aluminum die-casting or wood may be used.
Further, in FIG. 5, 2d is a slit formed in the side end 2b of the operation panel 2 so as not to interfere with the rotation of the hinge 7 when the operation panel is rotated.
Further, reference numeral 10 denotes a reinforcing plate inserted in the longitudinal direction to reinforce the other side end 2b of the operation panel 2. In Figure 2, 11 is a mini graphic panel;
12 is the wiring duct, 13 is the display (CRT)
shows.

In the above embodiment, when inspecting the back side of the operation panel 2, the legs 5b of the cap 5 should be formed so that a gap is created between the lower side of the operation panel 2 and the tabletop plate 1a of the operation desk 1. For example, the operation panel 2 can be rotated upward by inserting a hand into this gap. Furthermore, since the cap 5 is made of synthetic resin or the like, it is easy to mold, and it is easy to form an inward recess on the outside of the cap 5. According to this, the operation panel 2 can be easily formed inside. (same function as the rib 5c), and on the other hand, the outer part can be used as a part to hold when rotating the operation panel 2 upward.

According to the present invention described above, since the operation panel is made of a single plate, the weight is significantly reduced, opening and closing is easy to handle, and since there is no welded part, it is easy to work, and no distortion occurs. Furthermore, there is no strict requirement for dimensional accuracy, and a relatively loose size is sufficient, and there is no need for end face processing, so it is sufficient to just fit the cap, or it is sufficient to finish the end face to a certain extent. Furthermore, since the operation panel is made lighter, a smaller hinge is sufficient.
