Abstract

PURPOSE:To install switch covers allowable to mount and dismount it on/from an operation panel on which numerous push switches are provided, and to make the push switches having a high operation frequency operative, while to make the push switches having a low operation frequency inoperative. CONSTITUTION:On the rear side of a switch cover main body 10, numerous recessed holes 12 are provided, and lid members 20 are to be installed on the recessed holes 12. After the lid members 20 are installed on the positions corresponding to the push switches 4 having a low frequency of operation on an operation panel 3, the switch cover main body 10 is installed on the operation panel 3. The push switches at the positions the lid members 20 are installed are made inoperative thereafter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switch cover, and more particularly to a switch cover suitable for being applied to various devices provided with an operation panel having a large number of push switches, for example, an operation panel of a dental treatment unit. .

[0002]

2. Description of the Related Art FIG. 2 is a view showing a work table section in a dental treatment unit as an example of an apparatus equipped with an operation panel to which the present invention is applied. In the figure, 1 is an instrument holder and 2 is dental. Various instruments to be used for treatment, 3 are various instruments and other equipment, for example, an operation panel surface having a large number of pressing switches 4 for controlling up and down of the treatment chair, erecting, etc. On the work table, as is well known, in dental treatment, the operator pulls out a desired instrument 3 from the instrument holder 1 and operates the push switch 4 to move the instrument 3 to, for example, It is driven in a mode according to the instruction of the push switch 4.

As described above, recent various devices have a large number of pressing switches on the operation panel surface, and by selecting and pressing these switches, the devices have various functions. ing. However, in some cases, all the switches are not always required, and for example, if the setting switch or the like is set to a desired value in the initial stage, it is hardly necessary thereafter.

[0004]

As described above, a large number of pressure switches are arranged on the operation panel surface, and, for example, pressure switches that are frequently used and pressure switches that are rarely used are mixed. In such a case, if you press a push switch that is used frequently and you accidentally press a push switch that is used infrequently, for example, the setting switch as described above, reset the setting value to a value different from the desired setting value. It is dangerous and causes a malfunction. Further, since a large number of switches are provided, there is a problem in that the user tries to operate the switch, in other words, the target switch cannot be immediately confirmed.

[0005]

In order to solve the above-mentioned problems, the present invention provides (1) a switch cover detachably mounted on a surface on which a large number of pressure switches such as an operation panel are arranged. The switch cover is detachably inserted into the hole of the substrate, the substrate having a hole larger than the pressing surface of the pressure switch at a position corresponding to the pressure switch, the transparent sheet covering the surface of the substrate, and the hole of the substrate. A lid member having a recess larger than the pressing surface of the pressing switch on the bottom, and (2) the substrate and the sheet are integrally formed, and (3) the substrate and the sheet. Is a material that can be autoclaved.

[0006]

The operation panel is detachably mounted on an operation panel provided with a large number of pressing switches, and the pressing switches that are frequently used can be operated, and the pressing switches that are rarely used can be made inoperable.

[0007]

1 is a view for explaining an embodiment of a switch cover according to the present invention. FIG. 1 (a) shows a switch cover body 10 and a lid member 20 incorporated in the switch cover body 10. FIG. 1B is a perspective view separately shown, and FIG. 1B is a cross-sectional view of a main part when the cover member 20 is incorporated in the switch cover body 10 and mounted on the operation panel. The switch cover body 10 is made of, for example, a transparent (semi-transparent) material that can be autoclaved, such as silicon rubber or Ultem. The front surface is formed into a flat surface 11, and the back surface 12 has a large number of holes 12. The lid member 20 is mounted in the hole 12.

The hole 12 of the switch cover body 10 has a size into which at least the lid member 20 is inserted. For example, one hole or a plurality of lid members can be mounted in one hole. The lid member 2 is placed in the hole or at a desired position in the hole.
0 is installed.

The lid member 20 is, as shown in FIG.
The front surface 21 is formed into a flat surface and has a recess 22 on the back surface,
This concave portion 22 is larger than the area of the push switch on the operation panel, and therefore, when the concave portion 22 side of the lid member 20 is placed on the push switch, the side leg of the lid member 20 is placed on the push switch. It is formed so that it does not exist.

In use, after mounting the above-mentioned lid member 20 in the hole 12 on the back side of the switch cover body 10 corresponding to a push switch which is rarely used on the operation panel, with the concave portion 22 facing downward, The switch cover body 10 is shown in FIG.
As shown in (b), it is mounted on the operation panel 3. At this time, when the lid member 20 is formed of a transparent member, the pressure switch that is made unusable by the lid member can be visually inspected, and what function the pressure switch is made unusable. You can know. However, when it is rather annoying to be visible, it is preferable to use an opaque member.

FIG. 1B shows an example of a switch cover body in which a large number of recessed holes 12 are formed in a single member and the lid member 20 is inserted into the recessed holes 12. The present invention is not limited to the illustrated example, and for example, the switch cover body 10 may be formed by a substrate having a through hole and a transparent sheet attached on the substrate. By doing so, the switch cover main body can be manufactured more easily and inexpensively.

[0012]

As is apparent from the above description, since a pressure switch which is not normally used is disabled for an operation panel having a large number of pressure switches, the switches are erroneously operated. There are no worries and safe operation is possible. Since the switch cover body can be removed from the operation panel, it can be autoclaved and is hygienic. By making the switch that is not normally used invisible, it is easy to operate and there is an advantage that erroneous operation is eliminated.
