Description

[Detailed Description of the Invention] Technical Field The present invention provides a dental treatment chair, more specifically, a foot-operated switch is provided on the base of the dental treatment chair, and the switch is operated by the foot to drive a dental treatment instrument. This invention relates to a dental treatment chair that controls the

PRIOR TECHNOLOGY In general, a foot controller is provided in dental treatment, and the drive of a dental treatment instrument is controlled by the foot controller. Conventionally, this foot controller is provided separately from the dental treatment chair. It is designed to be used by being pulled out from the base of the dental treatment chair using a cord or hose. Therefore, during medical treatment, the surgeon (doctor) generally performs the treatment from the back of the treatment chair, but depending on the treatment area, it may be necessary to change the position and perform the treatment. In this case, the position of the controller also had to be changed, which made the medical work cumbersome and reduced work efficiency. Furthermore, the foot controller must be moved every time the floor is cleaned, which is also troublesome.

Purpose The present invention was made in order to solve the problems of the conventional technology as described above.In particular, it provides a foot-operated switch on the base of a dental treatment chair, and the switch can be operated from any treatment position. The purpose of this invention is to provide a dental treatment chair that has improved operability and work efficiency, and also allows for easy and clean floor cleaning.

Configuration Fig. 1 is a side view for explaining one embodiment of the dental treatment chair according to the present invention, and Fig. 2 is a plan view, in which 1 is a contour seat, 2 is a backrest, and 3 is a headrest 4 is a base part, 5 is a foot operation plate, one or more switches are disposed under the foot operation plate 5, and when the switch operation plate 5 is pressed, any one of the One or more switches are turned on. During treatment, the operator takes out a desired dental treatment instrument from an instrument holder (not shown) (at this time, the holder switch is turned on),
Next, the foot controller is operated to start the instrument; however, in this case, the operator is not always in a fixed position, but moves to a position that is easier to treat depending on the area to be treated. Therefore,
In the conventional device, as described above, the foot controller is moved to a position where it can be easily operated each time, but the moving operation is troublesome and also reduces work efficiency. The present invention was made in order to solve the problems of the conventional technology as described above, and takes into account the size, shape, etc. of the foot operation board 5, and provides a relatively wide area on both sides and rear of the dental treatment chair. At the position (for example, range A indicated by the dashed line in FIG. 2), the foot operation plate 5
It is designed so that it can be operated. In addition, the second
In the figure, the shape of the foot operation plate 5 is shown as a semicircle, but it is easy to understand that the shape and size of this foot operation plate can be selected to be any shape and size that makes it easy to operate the foot. Good morning.

FIG. 3 is a side configuration diagram for explaining another embodiment of the present invention. In the figure, parts that have the same functions as those in FIGS. It has the same reference number as . In Figure 3,
Reference numeral 6 denotes a link device for vertical movement of the lower table. In the dental treatment chair shown in FIG. I'm trying to adjust it. However, in this type of dental treatment chair, there is a risk that something may get caught in the B section between the link device 6 and the base portion 5. Therefore, a safety switch is provided in the base portion, and when the link device 6 is lowered, the link device 6 If an object is caught between the link device and the base portion 5, the object activates the switch to stop the link device from lowering. Therefore, in this type of dental treatment chair, as well as in the dental treatment chairs shown in Figs. Then, the foot controller is operated to turn on the start switch. According to the present invention, the safety switch provided on the base can also be used as the start switch of the foot controller. That is, by picking up the instrument and then pressing the foot operation plate 5 to turn on the switch, it is possible to prohibit the lowering movement of the chair and at the same time start the instrument. However, if the instrument is not picked up, the instrument will not move and will only stop the chair, so the instrument may not always operate and it may be difficult to maintain sufficient safety. can. In the embodiment shown in Fig. 3, it is also possible to have the switch provided on the base serve both the safety switch and start switch functions as described above, but it is also possible to provide the safety switch and start switch separately. It is easy to understand that it is okay.

Effects As is clear from the above explanation, according to the present invention, the operator can operate the start switch at any treatment position, so operability is very good, and the operator can perform treatment without having to worry about his feet. This allows you to concentrate on your treatment work,
Work efficiency can be improved, and there is no risk of erroneous operation. Furthermore, since the controller section including the switch and foot operation board is integrally attached to the base section of the dental treatment chair, floor cleaning becomes very easy and the treatment room can be kept clean.
