る。In FIG. 1, first, the illumination lamp support column 7 is elevated until the patient approaches the dental treatment chair installed on the base 1 and sits thereat. The illuminated lamp 5 is also in the raised position.
次いで、患者が着席すると背板２が治療に適した所定の
角度位置に倒れ、同時にステップ３も上昇して延びると
共に、それに追従して照明灯支持支柱７が下降して、治
療に適した照明灯点灯高度位置で停止する。Then, when the patient is seated, the back plate 2 falls down to a predetermined angular position suitable for treatment, and at the same time, step 3 also rises and extends, and the illumination lamp support column 7 descends following it, and the illumination suitable for treatment is illuminated. Stops at altitude when the light is on.

る。When the patient stands up the chair back plate 2 for gargle or the like during treatment, the illumination lamp support column 7 also rises, and the spitton 4 is used to finish the gargle and tilt the back plate 2 to the treatment position again. Then, the illumination lamp support column 7 also descends. Therefore, the support arm 6 and the illumination lamp 5 are prevented from coming into contact with the patient's head and the like, and the illumination lamp can be returned to the position suitable for treatment.
以上の作動は、歯科治療椅子に設けられた背板２の角度
位置検知センサからの信号を受けて応動する照明灯支持
支柱基部に設けられた昇降機構８によって行われる。The above operation is performed by the elevating mechanism 8 provided at the base part of the illumination lamp support column which responds to a signal from the angular position detection sensor of the back plate 2 provided at the dental treatment chair.

こととなる。That is, when a fluid (for example, compressed air) is press-fitted into, for example, the fluid inlet / outlet port 14 'in response to a signal from the sensor,
Since the piston rod 13 of the compound fluid cylinder 12 is pushed upward, the base hollow tube body 16 connected to it by the connecting rod 15 is also raised upward at the same time, and therefore the illumination lamp support column 7 is raised. The illuminating lamp 5 is raised.
次に、照明灯５の点滅状態については、照明灯５は歯科

１６の上昇を停止する。Now, when the fluid cylinder 12 of the lifting mechanism is pushed upward by receiving a signal from the sensor of the dental treatment chair and the base hollow tube body 16 is raised to the vicinity of the bearing 11 ', the operating piece 20
Comes into contact with the lift limit switch 17 and the fluid cylinder 1
The on-off valve for supplying the pushing-up fluid 2 is closed, and the raising of the base hollow tube body 16 is stopped.

９壁との接触、滑動をスムーズにしている。As shown in FIG. 3, in order to prevent the base hollow tubular body 16 from rotating in the horizontal direction, a vertically elongated guide groove 19 is provided at the end of the column box 10, and the tubular body 16 is provided with a projecting groove. The slide piece 21 thus formed is inserted. In the case of this example, the slide piece 2
A roller 23 is axially attached to the end of the guide groove 1.
9 Contact with the wall and smooth sliding.

However, it is avoided that the illumination lamp 5 comes into contact with the patient's head, face, etc. during non-treatment-ascending / descending during treatment. At the same time as the operation, the illumination lamp blinks automatically to save energy,
You can save the trouble of manually blinking.
本考案の昇降機構は、従来の照明灯の昇降方式に比し
て、機構的に簡単でしたがって故障もなく、かつ照明灯
の昇降調整も容易適確に行える。The elevating mechanism of the present invention is mechanically simpler than the conventional elevating and lowering method of the illuminating lamp, and therefore has no trouble, and the illuminating lamp can be adjusted easily and accurately.

ましいものである。In the above embodiment, an example in which air pressure is used as the fluid cylinder has been described, but hydraulic pressure can also be used. In that case, pressure transmission of the fluid is directly and accurately performed, so movement of the illumination lamp support column This is preferable because there is no play or blurring.
さらになお、流体シリンダによる駆動に代えてモータド
ライブ方式を採用することもできる。Furthermore, a motor drive system can be adopted instead of the drive by the fluid cylinder.
