Next, the operation of the hairdressing and beauty chair configured as described above will be described. First, in order to seat the subject on the chair 2, as shown in FIGS.
On the other hand, the chair 2 is rotated so that the backrest 22 faces the ball so that the ball 12b is fitted into the groove 13b. Since the chair 2 is locked in this state, the chair 2 does not rotate when the subject sits on the seat portion 21, and can be safely seated.

Then, when the practitioner sits down and the practitioner rotates the chair 2 to a work position for applying a perming agent or a color agent as shown in FIGS. 6 and 7, the ball 12b is moved.
Is once detached from the groove 13b, fits into the groove 13a, and stops at the treatment position. Therefore, the practitioner can perform the operation in a stable state.

Next, in order to wash the hair of the practitioner after the treatment is completed, the chair 2 is rotated to the opposite side to the above-mentioned state, so that the chair 2 becomes the state of FIG. 5 and the backrest 22 becomes a shampoo ball. The position is opposite. In this state, when the motor 32a of the actuator 31 is energized, the projecting rod 31b gradually projects, so that in FIG. 8, the first parallel arm 32 is rotated counterclockwise about the pivotal fulcrum with the pedestal 13d.

As a result, the extension piece 21d is raised,
Since the second parallel arm 33 that moves parallel to the first parallel arm 32 is present in the extension piece 21d, the seat portion 21 attached to the extension piece 21d is parallel to the shampoo ball A direction. The ascending operation is started, and the head of the seated subject is moved toward the neck receiving portion A1 of the shampoo ball A. At this time, a rotational force acts on the actuator 31, but the actuator 31 is not attached to the mounting substrate 2.
Since it is rotatably attached to 1c, the projection rod 31b of the actuator 31 can freely project.

When the first and second parallel arms 32 and 33 move in parallel, the second backrest assisting arm 34 whose one end is axially supported by the second parallel arm 33 is displaced. Since the other end of the second backrest assisting arm 34 is pivotally supported by the first backrest assisting arm 35, the second backrest assisting arm 34 is rotated counterclockwise, and thus the backrest is supported. Since the arm 36 is pulled rightward in the drawing,
Since the backrest 22 is in the laid-down state, and further, the front-drip assisting arm 38, which is also fixed to the rotary shaft to which the first backrest-assisting arm 34 is fixed, is rotated in the counterclockwise direction, the front-drip assisting arm 38 is The front drooping arm 37 pivotally supported on the front drooping arm 37 also brings the front drooping 23 into a prone state (see FIG. 9).

The state of FIG. 9 is the basic hair washing position, but when the sitting height is low like children and girls, the neck of the person to be washed does not reach the neck receiving portion A1 of the shampoo ball A. Therefore, when the motor 31a is further energized, the seat portion 21 moves obliquely upward (direction of shampoo ball) while maintaining the state of FIG. 9 for the reclining angle of the backrest 22 and the front drip 23 (FIG. 10). .

The movement from FIG. 8 to FIG. 9 is stored as a preset movement amount, and the movement from FIG. 9 to FIG. 10 is preferably adjusted by the operation of the practitioner. is there.

After washing the hair, when the motor 31a of the actuator 31 is energized in the direction opposite to the rotating direction, the projecting rod 31b is gradually retracted. 2 starts descending,
Finally, it descends to the position shown in FIG. 8 and stops.

Next, FIG. 11 is a flow chart showing the operation for performing the above operation. As a circuit for performing the operation of this flowchart, a backrest 22
A switch S, such as a toggle switch, mounted on the upper back of the is connected to a computer having a built-in timer and memory. Then, when the computer operates the switch S for a predetermined time or more, the computer shown in FIGS.
Energize the motor 31a to perform the automatic operation up to
Further, when an operation shorter than the predetermined time is performed, the motor 31a is energized for the duration of the operation.

The operation will be described below with reference to the flowchart of FIG. It is determined whether or not the result of operating the switch S is shorter or longer than a predetermined time set in advance (step S1), and a predetermined value is set for the operator to perform an automatic operation (automatically move from FIG. 8 to FIG. 9). If the operation has been performed for more than a time, the motor 31a is energized to start the automatic operation (step S2).

During this automatic operation, it is judged whether or not another switch such as a switch conventionally installed on the side surface of the hairdressing and beauty chair is operated (step S3), and the other switch is operated. When operated, the motor 3
The energization of 1a is cut off, and the raising of the seat portion 21 and the reclining of the backrest 22 and the front drop 23 are stopped (step S4).

During the auto operation, the safe operation time from the start of energization of the motor 31a to the end of the auto operation under normal conditions and the actual motor 3
1a is compared with the operating time during which the motor is energized (step S5), and when it is determined that the operating time is long, for safety reasons, the motor 31a is deenergized and the operation ends (step S5). S4).

If the above judgment indicates that the seat 21 has proceeded normally, the seat 21 is raised in the automatic operation and the backrest 2 is moved.
2 and the limit switch (not shown) installed at the down position of the front drip 23 is judged whether or not it is turned on (step S6), and when it is judged that each limit switch is turned on, the motor 31a is energized. Is cut off to end the operation (step S4).

On the other hand, if it is determined in step S1 that the time when the switch S is operated is shorter than the preset time, it is determined that the operation is manual (step S7), and the operation of the switch S is performed. It is judged whether or not it is in the off state (step S8), and when it is judged that the operation of the switch S is in the off state, the energization to the motor 31a is cut off at that time and the operation is finished (step S4).

Then, it is judged whether or not the limit switch (not shown) installed at the raised position in the manual operation of the seat portion 21 is turned on (step S9), and the limit switch is turned on. When judged, the power supply to the motor 31a is cut off to end the operation (step S4).
