BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a hairdressing chair according to an embodiment of the present invention. 1
Is a seat base plate, and the seat base plate 1 is configured to be vertically movable by a well-known elevating means 2. Numeral 3 designates a front hanging member rotatably supported in front of a frame 11 extending above the seat base plate 1, and numeral 4 designates a backrest pivotally supported in a rotatable manner behind the frame 11. The front hanging 3 and the backrest 4 are formed so as to be able to rise and fall by a driving source such as a hydraulic cylinder (not shown). The above is a known structure.

Reference numeral 5 denotes a pivotal connection point 5 between the front hanging 3 and the underframe 11.
1 is a pair of left and right first links that are pivotally supported at one end, and are formed on the shaft 52 and the seat substrate 1 that are bridged between the intermediate portions of the pair of first links 5. A drive source 6, such as a hydraulic cylinder, is pivotally supported, and pivots around the harmful 1 link 5 at the pivot point. In addition, a guide rail 53 that is bent in an L-shape is mounted in the longitudinal direction between the pair of first links 5. Note that 54
Is a stopper that comes into contact with the seat substrate 1 at the position where the seat is lowered most.

Reference numeral 7 denotes a pair of left and right second links, one end of which is pivotally supported by a mounting plate 12 fixed to the seat substrate 1. The other end of the second link 7 and the other end of the first link 5 Is a mounting bracket 81a hanging from a rear substrate 81 of a rear seat portion 8 described later.
Is supported by a certain distance. A potentiometer 71 is mounted on one of the second links 7, and a lever 72 is rotatably mounted between the rotation shaft of the potentiometer 71 and the seat substrate 1. Therefore,
When the second link 7 is displaced, the resistance value of the potentiometer 71 changes.

The seat portion is divided into a rear seat portion 8 and a front seat portion 9.
Mounted on top. Further, after the adjacent portions of the front substrate 81 and 91 are mutually rotatably shaft, the distal end side of the front substrate 91
Is in a free state.
A roller 92 that moves on the guide rail 53 is fixed to the back surface of the roller.

Next, the operation based on the above-described configuration will be described. The horizontal state of the front and rear seats 9 and 8 in FIG. 1 is a position where the subject is introduced and hair-cut, and at this time, the piston 61 of the drive source 6 is in a slightly discharged state than the position where the suction is most performed. is there. In this state, the stopper 54 is not in contact with the seat substrate 1.

When shifting from this state (reference position) to the front shampoo, supply oil or the like to the drive source 6 to discharge the piston 61 to the position shown in FIG.
The first link 5 is rotated clockwise about the pivot point 51. The rotation of the first link 5 causes the mounting bracket 81a to rotate.
The rear seat portion 8 rises while slightly moving forward through. The second link 7 is also rotated clockwise with the rotation of the first link 5, so that the resistance value of the potentiometer 71 changes.

When the rear seat 8 is raised, the front seat 9 pivotally supported by the rear seat 8 is rotated clockwise about the pivot point 51. At this time, the roller 92 is guided by the guide. Since it moves while rolling on the rail 53, the pivot point of the rear seat portion 8 and the front seat portion 9 does not move downward.

Then, the second link 7 is rotated, and a change in the resistance value of the potentiometer 71 is monitored by a control device (not shown). When the resistance value reaches a preset value (when it reaches the shampoo position in FIG. 2). The oil supply to the drive source 6 is stopped. In this state, since the rear seat portion 8 is almost horizontal and the front seat portion 9 is inclined, the seated subject does not suffer from the reclining posture, and is in a comfortable state. You can receive front shampoo. Even after stopping at the above-mentioned position, the height can be adjusted by manually supplying or removing the oil.

After the shampooing operation is completed, the weight of the seated subject and the front and rear seat portions 9 and 8 applied to the drive source 6 by opening the oil supply valve into the drive source 6 are opened.
The descent is started by the load such as. When the resistance value of the potentiometer 71 reaches a preset value (when the resistance value drops to the position shown in FIG. 1), the control unit closes the oil supply valve, so that the front and rear seats 9 and 8 are maintained in a horizontal state.

In order to shift to the state shown in FIG. 3 (the position where the rear seat portion 8, which is the comfortable position, is further lowered from the horizontal position) in the horizontal state, the oil supply valve is opened again to drain the oil. The rear seat 8 starts to descend, and the stopper 54
When the potentiometer 71 detects the position at which the abutment comes into contact with the seat substrate 1, the control device closes the oil supply valve and the descent stops. In this state, since the roller 92 is located on the horizontal portion of the guide rule 53 in the front seat portion 9, the front seat portion 9 is maintained in a substantially horizontal state.

Next, a description will be given of a case in which the state shifts to the state shown in FIG. When the oil is continuously supplied to the drive source 6 even after the shampoo position is reached for the drive source 6, the rear seat 8 is moved to the first,
Since the second links 5 and 7 are in a parallel state, the rear seat portion 8 rises substantially vertically. In addition, the front seat 9 is slanted because the rear seat 8 is raised, and the roller 92 is supported by the guide rail 53 in this state, so that the slant is maintained.

When the potentiometer 71 reaches a preset resistance value, the control device stops the oil supply to the drive source 6, so that the state shown in FIG. 4 is maintained.
Even if a subject with a low sitting height is seated, the head can be at a high position and the feet can be placed on the front seat back 9, so that the operation can be performed in a stable state.

Although the position detection in the various operations described above is performed by the potentiometer 71 in this embodiment, a known position detecting means (for example, a method using a laser beam, a microswitch, Needless to say, the method of arranging each position) can be used.

[0021]

According to the present invention, as described above, the seat is
Divided, the rear seat is moved up and down almost horizontally by the drive source from the horizontal state, and the front seat is shifted diagonally, so that the front shampoo is easier to lean forward and the front seat is raised to the highest position By doing so, the practitioner with a low sitting height, such as a child, can be moved upward to facilitate the practitioner's operation.

Further, since the rear seat portion can be further moved from the horizontal state to the lowering position, the operator can take a more comfortable posture, and further, each work position can be detected by a position detecting device such as a potentiometer. Since control is performed by the means, various controls do not have to be performed by the practitioner due to automation, and have an effect that the user can concentrate on the treatment.
