Abstract

PURPOSE:To make it possible to move a light for its position and angle automatically by providing a control mechanism for moving a light part forward and backward for a distance corresponding to a moving distance of a back frame and performing fine adjustment of an angle of depression automatically. CONSTITUTION:For a change from care at a standing attitude to care at a sitting attitude, a switching 7 provided at a side surface of a back frame 6 is operated. The drive part of a slide shaft 3 is driven interlocked with the switch to feed the slide shaft forward for a corresponding quantity to the moving quantity of a mouth part. A drive cam 11 connected with a motor M is eccentric, and the direction of a light part 4 supported by a ball joint 5 can be changed up/down and right/left by this eccentric motion. The position of the light part can be thus adjusted constantly automatically corresponding to the moving quantity of the back frame when it gets to stand or be inclined.

(Means for Solving the Problems) The present invention provides the following features:
The present invention provides a dental light in which the position and angle of the light part can be automatically moved, that is, a support stand, a slide shaft held by the support stand that can be freely drawn out, and an angle that can be adjusted freely. A slide shaft support drive unit provided, a light unit provided at the tip of the slide shaft, a device for finely adjusting the angle of depression of the light unit, and a back frame adjustment device in response to the amount of inclination of the back frame of the treatment table. It is characterized by comprising a control mechanism for automatically finely adjusting the lateral direction of the light section and the direction of the depression angle of the light section for moving the light section back and forth by a distance corresponding to the movement distance of the back frame when standing up and tilting. This is a dental light.

(Embodiment) An embodiment of the present invention will be described in detail with reference to the accompanying drawings. In FIG. A slide shaft 3 that fits into the slide shaft 3 and a light section 4 attached to its tip
First, the direction and position of the patient are determined based on the patient's body shape and other factors prior to the examination.

Generally, the angle between the ball J and the slide shaft 3 is fixed in advance, so the amount of feed of the slide shaft 3 (
The position of the light section can be changed by changing the direction of the arrow in the figure. Further, the depression angle of the light section 4 is automatically adjusted, but in this method, for example, the connection with the slide shaft 3 is made by using the ball joint 5.
This method may also be used.

In this way, once the light position is set,
For example, when changing from a standing position to a seated position as shown in the figure, the amount of backward movement of the oral cavity (indicated by the dotted line in the figure) can be detected and the slide shaft can be moved forward by the corresponding amount. The distance between the light section and the light section can be kept substantially constant at all times. Note that the moving direction of the light part 4 as the slide shaft is extended is the direction of the extension line of movement of the oral cavity (considered to be a substantially straight line) when the back frame is erected (or tilted), as will be described later. It is preferable that the light section substantially coincide with the cavity and that the light section always be in front of the cavity.

By the way, when changing from standing medical treatment to sitting medical treatment, the back frame 6 is tilted to the position shown by the reference numeral 6', and the switch 7 provided on the side of the back frame 6 is operated as shown in the illustrated example. Let's do it. Therefore, the slide shaft driving section is driven in conjunction with the switch, and the slide shaft is moved forward by an amount synchronized with the above-mentioned movement amount. In the illustrated example, the maximum inclination L of the back frame is about 80 degrees and about 4901 degrees in length, so if you move the slide shaft forward by the same distance,
The distance between the light part and the oral cavity will be kept constant. Note that the time required for tilting at this time is about 7 seconds at most.

Therefore, if the moving speed of the back frame when tilting and the feeding speed of the slide shaft are made the same in advance, the feeding amount can be controlled by time. In other words, the slide shaft only needs to be driven for about 7 seconds. FIG. 2 illustrates the shaft feeding mechanism,
A rack gear 8 is provided at the rear end of the slide shaft, and a binion gear 10 connected to a forward/reverse motor 9 is engaged with this rack gear, causing the forward/reverse motor to move the slide shaft by an amount corresponding to the above-mentioned amount of inclination. energize it to come out. For example, motor rotation speed 1.40O
RPM, using pitch 31 gear, 7 in 1 second
01 movement, therefore 4901 in 7 seconds
I will have to move. In other words, when the above-mentioned horizontal configuration is used, the movement speed of the back frame when the back frame is raised and tilted is the same as the slide shaft's feeding speed, so it is only necessary to move the switch in common, and the response is It is preferable because it is good and makes vomiting easier.

Fig. 3 is an enlarged partial sectional view of the tip of the slide shaft 3, and shows a specific example equipped with an automatic fine adjustment device that can automatically control the horizontal, vertical, and depression angle directions of the light section remotely with just a switch. It shows. The driving force 11 connected to the motor M is eccentric, and due to this eccentric movement, the light part 4 supported by the ball joint 5 changes its direction over the range shown by the arrow in the figure (between the positions shown by the broken line). It can be moved up, down, left and right. The motor M may be controlled by the above-mentioned switch 7, in which case the operator can control the position of the back arm, the position and direction of the light section, and the depression angle direction by simply operating the switch 7.

(Effects of the Invention) As described above, according to the present invention, when the back frame is raised or tilted, the position of the lie 1 section is always automatically adjusted in response to the moving scenery, and the depression angle direction of the light section is always adjusted automatically. The operator can also adjust the position and direction of the light part automatically, so the operator does not have to reach out and adjust the position and direction of the light part. ..
