Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shadowless dissolution arm that can automatically return up to one line of the 51,1,1J machine.

Jumetsu, Yoriyama (゛1 night original treatment used)
The chair is made of 414, and the chair can be operated by hydraulic cylinders, etc., and can be lowered, raised, and folded down by the backrest. Since the surgical light does not have a mechanism that can be activated by operating a switch, the operator (dentist) must first turn off the surgical light at the end of patient treatment, stand up and move the surgical light far away (pull it, then reset it). By turning on the switch, it was necessary to raise the backrest and lower the chair.Therefore, if the surgeon forgets to remove the surgical light and turns on the switch, the patient may There was an inevitable danger of a collision.

As a result of various studies, the inventors of the present invention have incorporated an air cylinder into the arm of the operating light, which is linked to the setting of chair glue immediately after dental treatment, to automatically return the operating light to the standby position without colliding with the patient. The present invention was completed by discovering that it is possible to manufacture a shadowless dissolving arm that can move the shadowless dissolving light to a desired position manually as in the past.

That is, the present invention provides an arm that supports a surgical light attached to a dental treatment unit, and has an arm that is rotatable in the horizontal direction (6 a connecting member, an arm body whose one end is pivotally connected to the arm connecting member so as to be rotatable in the vertical direction, and an end of the arm body on the opposite side of the arm connecting member to be rotatable in the vertical direction. A lamp connecting member attached to ((4), and a lamp body pivotally attached to the lamp connecting member so as to be freely rotatable in the horizontal direction, and a lamp body is attached to the end opposite to the shield portion (14) so that the lamp body can be freely rotated in the vertical direction. and a lamp body support member supported by the arm body, and within the arm body there is a connecting part A whose one end is attached to the arm connecting member so as to be rotatable in the vertical direction, and a connecting part A which is fixed to the arm body. A brake brake that comes into contact with the connecting part shrine and controls the movement of the connecting part shrine.
The connecting portion 1,1t is fixedly installed).
Between the brim and the nose heath, the connecting part (4) is rolled up and the arm body rotates downward.
The cylinder is fixed to the arm body with screws 1 and 11.
An air cylinder or internal device that moves the link in the direction of tension of the compression coil link.
The present invention provides a shadowless dissolution arm characterized by having a stain.

Hereinafter, the shadowless dissolution arm according to this research will be briefly explained based on the embodiment shown in the drawings.

It is an electrical circuit diagram of an embodiment including four solenoid valves shown in the figure.

In the drawings, reference numeral 1 denotes a rotary arm that is horizontally rotatable and is installed in the dental treatment unit, and in the N8 embodiment, there is a ball 1a protruding from the dental treatment unit (not shown). is mounted horizontally. In this structure (J, the case where the rotating arm 1 is freely attached to the ball l+, the rotating arm 1\'1 is fixed to the ball 1a, and the ball 1a has a gap between both hands ζ1) -

A brake heath is fixed inside the main body 3 and comes into contact with the connecting member 7 to suppress the movement of the connecting member 7. 9 is a stopper fixed to the connecting member 7, as shown in Fig. 2 (I3).
The connecting member 7 is connected to the arm connecting member 2 as shown in the diagram.
If it is below the B position, the stopper 9 must be closer to the arm connecting member 2 than the brake heath 8,

This is an air cylinder that moves the connecting member 7 in the pulling direction, and in the case of a type in which the air cylinder 11 at the mouth automatically returns to the initial ju1 position by following the sufflage lug inside the cylinder lla. , month, Ili+ 'i is not supplied with a'3 and is 1ku no I-I Tsudo 11
11 and the abutting part of the histone rod 1111 of the connecting member 7? J-ru. In addition, the cylinder installed inside the no arm tree 1 hole 3 is called the core cylinder 11.
The reason for this was that there was no need to worry about contamination with oil like in oil cylinders, and the dental clinic had compressed air used for other equipment, so the air was not used in the cabinet. This is due to the fact that it can be used and furthermore that the movement is ;1'1 et al.

Next, the operation of the arm of the surgical light according to the present invention having the above-mentioned 41η structure will be explained.

First, when we explain the case of moving the J-resight E and trI, we will explain how to move the lamp body (5). A force b/J (is applied to the arm main body 3 via the non-7 connecting part 4A4 where the connecting part 47 is attached -l\ Becomes movable relative to the main body 3 T-P-m The main body 3 can be moved vertically relative to the arm connecting member 2, and by moving the hand 1llII, the weight of the run 1 main body 6 etc. can be compressed. The balance is maintained in the same state as supported by the compressive force caused by the 1° suspension ring and the braking force applied to the brake piece 8.

At this time, the spring built into the cylinder 11a as the air cylinder 11 is activated.
If a type in which the piston rod 1111 returns to its initial position is used, the tip of the piston rod 1111 is connected to the connection s +. a
The J-arm main body 3 can be moved vertically relative to the arm connecting member 2 without contacting the contact portion of the piston rod 1111 of 7, and the air cylinder 11 automatically returns to the initial position. If a type that does not have a piston rod is used, the tip of one piston rod is
If the air flow path connected to the air cylinder 11 is open to the atmosphere, the arm body 3 is connected to the air cylinder 17.
'The arm connecting member 2 can be moved vertically without being affected by the cylinder 11.

In addition, in order to automatically return to the silent standby position using compressed air, an electric switch can be used to turn on and off the supply of compressed air from a compressed air source (not shown) attached to the dental treatment unit 1-. If this is done by activating the electric valve 1 shown in FIG. 4 through the air cylinder 11 as shown in FIG. Move arm body 3
rotates upward relative to the arm connecting member 2 and returns to the standby position. In this way, it is possible to move the surgical light far away to the initial standby position with a single switch operation,
As shown in Figure 5, the electric circuit for operating the treatment chair for each tooth has an electromagnetic pulp tongue installed in the mouth that operates the shadowless dissolution arm, allowing the operator to stand up with a single reset switch operation. There is no shadowless light, and the tooth 41 treatment is reset with Kawasaki Ryo's reset, and it is like a monkey returning to the pig [8]
The safety of people can be ensured.

In addition, in the figure, ``: μ press 511 switch, the same is the relay operation TI- (Le, 1: is, /-mal orb] /, jin is the normally closed relay contact, ! is the limit of the chair's movable range. 1" switch, @h< moves the chair'7
1'A is a solenoid valve that controls the supply and discharge of oil to the air cylinder, 05 is an electric valve (6 valves) that controls the supply and discharge of air to the air cylinder that moves the operating light arm, and ■ is a hydraulic valve 7'.
Small, up, down, up, and down are the steps to raise, lower, and raise the backrest of a dental therapy chair, respectively.

Give an example.

As explained above, although the surgical light arm according to the present invention has a simple structure, it not only ensures patient safety but also simplifies the operator's flow line and reduces operator fatigue. It has great value in dental therapy.
