[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hairdressing and beauty chair, and more particularly to a shampoo which allows the head to be positioned at a predetermined position of the shampoo ball even when the height of the subject is different when washing the hair in a supine position. The present invention relates to a hairdressing and beauty chair suitable for a chair.

[0002]

2. Description of the Related Art In a conventional hairdressing and beauty chair, when the hair is washed in a supine manner, the backrest is tilted while the seat is raised, and the neck of the subject is placed on a predetermined position of the hair-washing ball. However, if the height of the subject is too high or too low, the subject will shift the body in the front-back direction to adjust the neck part to a predetermined position. In addition to having to perform a troublesome operation for the practitioner, if the practitioner is a woman, the clothes will be disturbed and hated.

In addition, since the seat part moves up and down in a horizontal state,
There is a problem in that the subject is fatigued because the subject is forced to have an unnatural and unstable supine posture at the elevated horizontal washing position. Therefore, it is conceivable to make the foot side higher than the rear side (butt side) in advance to maintain a stable posture in the supine state, but in this case, it is difficult to operate because the buttocks are depressed when sitting and sitting down. There was also.

[0004]

Therefore, in order to solve the above-mentioned various problems, the applicant company has developed the technique disclosed in Japanese Patent Publication No. 7-89971. This is such that the distance between the seat surface and the hair-washing ball can be adjusted during hair washing according to the sitting height of the subject.

However, according to the technique of the present invention, since the arm provided with the cam hole is used as the operation mechanism for realizing the deformation operation of the chair, the operation is likely to be unstable, and
There is a problem that the cost becomes high because accuracy and labor are required for manufacturing and assembling.

The present invention is intended to solve the above-mentioned problems, and an object of the present invention is to stabilize the neck part at a predetermined position of the hair washing ball without shifting the seating position without distinguishing the height difference, Moreover, it is intended to provide a chair for hairdressing and beauty, which can take a supine posture in a natural posture and can easily take a seat away.

In the figure, A is a floor surface of a building such as a hairdressing salon, B is a wall surface of the building, C is a hair-washing ball attached to a wall surface B, and D is a hairdressing chair of the present invention fixed to the floor surface. The hair-washing ball C is arranged with a predetermined distance.

Next, the details of the hairdressing and beauty chair D will be described. 1 is a T-shaped base, and a horizontal portion 1a is placed and fixed on a floor surface A, and a hydraulic device 2 including an oil tank and a hydraulic pump is attached to the horizontal portion 1a. Reference numeral 3 is a hydraulic cylinder whose one end is fixed to the horizontal portion 1a of the base 1.

A T-shaped seat base 4 is provided with a seat substrate 5 attached to the horizontal portion. A standing plate 5a is fixed to the rear of the seat substrate 5 (leftward in the drawing), and one end of a connecting plate 6a is rotatably supported by a pin 5b on the standing plate 5a. A backrest 6 is attached to the other end of the connecting plate 6a. A front hanging board 7 is pivotally supported by a pin 5c in front of the seat board 5 (to the left in the drawing). The seat substrate 5
An integral sheet material 8 is formed on the front hanging substrate 7.

Reference numeral 9 is a first parallel link connecting the vertical portion 1b of the base 1 and the vertical portion of the seat base 4 with pins 9a and 9b, and 10 is a constant distance from the first parallel link 9. With the vertical portion 1b of the base 1 and the seat base 4 separated from each other.
A vertical parallel part is connected to each other by pins 10a and 10b to form a second parallel link, and the tip end connected to the seat base 4 is bifurcated to form a first forked part 10c and a second forked part 10d.

Further, the pin 10 of the second parallel link 10
The tip end of the piston in the hydraulic cylinder 3 is pivotally supported by the connecting bar 3b at a substantially intermediate portion connecting a and 10b. Reference numeral 11 denotes pins 10e and 6b for connecting the first forked portion 10c and the connecting plate 6a in the second parallel link 10.
A backrest link that is connected by means of and a reference numeral 12 is a front drooping link that connects the second forked part 10d of the second parallel link 10 and the front drooping substrate 7 by pins 10f and 7a.

Is pivotally supported. The seat substrate 5 is substantially parallel to the floor surface A (horizontal state) when the piston is contracted.
The length of each link is set so that

Next, the operation will be described based on the above configuration. At the lowest position (the position where the subject is seated on and off) shown in FIG. 1, the seat substrate 5 is in a substantially horizontal state, so that the subject can easily sit on and take off. When shampooing the hair of the subject in this state, if oil is supplied from the hydraulic device 2 to the hydraulic cylinder 3,
The piston gradually begins to extend.

When the piston extends, the second parallel link 10 connected to the piston by the connecting bar 3a is rotated counterclockwise. With the rotation of the second parallel link 10, the first parallel link 9 is also rotated in the counterclockwise direction, and the seat substrate 5 has a length of the first parallel link 9 that is slightly shorter than that of the second parallel link 10. However, since it is long, the seat substrate 5 is vertically lifted while inclining so that the front hanging substrate 7 side becomes higher.

When the second parallel link 10 is rotated, the first and second forked portions 10c, 10c of the second parallel link 10 are rotated.
The backrest link 11 connected to 10d by the pins 10e and 10f is pulled downward, and the front hanging link 12 is pushed upward. Thereby, the backrest 6 is the connecting plate 6
The front hanging substrate 7 is rotated in the down direction via a.

The pins 9a and 10 which are the connecting portions between the first and second parallel links 9 and 10 and the vertical portion 1b of the base 1.
When the line connecting a and the first and second parallel links 9 and 10 are moved to the first position, which is a position where they are substantially at right angles,
As described above, since the seat substrate 5 is rotated in the counterclockwise direction, it is possible to receive the washing of hair in a stable state without having an unnatural posture in the supine state, and to extend the washing line on the extension line of the backrest 6. since the neck receiver C ₁ position opposed to placing the neck of the ball C, and when the high sitting height the practitioner can place the neck該被practitioner neck receiving portion C _1.

However, in the case of a subject whose seating height is low, the neck does not reach the neck receiving portion C ₁ , so that oil is further supplied into the hydraulic cylinder 3. When oil is supplied into the hydraulic cylinder 3, the piston is further extended. As a result, the first and second parallel links 9 and 10 are further rotated in the counterclockwise direction, so that the seat substrate 4 moves up to the second position in FIG.

In the second position, the backrest 6 approaches the hair-washing ball C, so that even if the person to be treated has a low sitting height, the neck portion is close to the neck receiving portion C _1. Even if you do not move your body from the sitting state, you will be in a natural state and move to a hair washing state. Moreover, the first
Backrest 6 when moving from position to second position
Since there is almost no change in the angle of the front hanging board 7, there is little change in the posture of the subject.

Next, a second embodiment will be described with reference to FIGS. The same reference numerals as those in the first embodiment described above indicate the same members, and the description thereof will be omitted. Whereas the link in the above-described first embodiment is composed of four links on one side, the one in the second embodiment is composed of six links on one side. There is no change in the transition from the position position to the highest position to the second position position.

The second embodiment will be described in detail below. As in the previous embodiment, the vertical portion 1b of the base 1 and the seat base 4 are connected to each other by two first and second parallel links. The points of connection by 13 and 14 are the same, but in the present embodiment, the first
The parallel link 13 is L-shaped, and the second parallel link 14 is linear.

Reference numeral 15 denotes a pin 13a at the tip of the first link 13.
In the second position, the drive link is connected to the first parallel link 13 and the seat base 4 to prevent contact with the pin 13b. Reference numeral 16 is a V-shaped backrest link, one end of which is connected to the connecting plate 6a by a pin 6b, and the other end is connected to the tip of the drive link 15 and the pin 15a.

Reference numeral 17 designates an L-shaped first intermediate link whose one end is connected to a pin 15a connecting the drive link 15 and the backrest link 16, and the bent portion is pin 17a on the seat substrate 4.
Is supported by. A stopper pin 17b is erected on the other end of the first intermediate link. Reference numeral 18 is a linear second intermediate link whose one end is axially supported by the seat substrate 4 by the pin 17a, and the stopper pin 17b is in contact with the side surface.

Reference numeral 19 is the first and second intermediate links 17, 1.
A contraction spring stretched between the two links 17,
The pin 17a pivotally supporting 18 is stretched so that the angle does not spread, and the stopper pin 17b acts so that the angle does not fall within about 90 degrees. The other end of the second intermediate link 18 is connected to the front hanging link 18 by a pin 18a.

Next, the operation will be described based on the above configuration. Even in the present embodiment, the seat substrate 5 is in a substantially horizontal state at the lowest position shown in FIG. In this state, oil is supplied to the hydraulic cylinder 3 to extend the piston, and the first and second parallel links 13 and 14 move the pin 13
When the seat substrate 5 is rotated counterclockwise to a position substantially perpendicular to the line connecting c and 14a, the length of the first parallel link 13 of the seat substrate 5 is slightly longer than the length of the second parallel link 14, so that Since the seat substrate 5 vertically moves while inclining so that the front hanging substrate 7 side becomes higher, and the drive link 15 is lowered by the first parallel link 13, the backrest link 1
6. The backrest 6 is laid down via the connecting plate 6b.

Further, when the drive link 15 is lowered, the first
Since the intermediate link 17 is rotated counterclockwise, the first link
The stopper pin 17b of the intermediate link 17 rotates the second intermediate link 18 counterclockwise. As a result, the front hanging link 20 rotates the front hanging board 7 in the falling direction to the first position shown in FIG.

In this state, when the neck of the person to be treated does not reach the neck receiving portion C ₁ of the washing ball C, the piston of the hydraulic cylinder 3 is further extended to move in the direction of the washing ball C. The second position shown in FIG. 6 is reached. Therefore, since the tip of the backrest 6 is close to the hair-washing ball C, the neck portion can be placed on the neck receiving portion C ₁ even when the seat height of the subject is low, and
At the time of shifting from the first position to the second position, the angle change of the backrest 6 and the front hanging board 7 is small, and the posture change of the subject is also small.

The action of the contraction spring 19 is as follows: when going from the ascending position to the descending position, and when the descending position in FIG. 4 does not return to the standing state only by the weight of the front drip or the weight of the subject's foot. Alternatively, in order to prevent backlash from occurring in the standing state, the spring force is used to return to the state of FIG. 4 or to prevent backlash.

Further, in any of the above embodiments,
It is needless to say that it is possible to adjust to the sitting height of the subject by stopping it during the transition from the first position to the second position. It may be finely adjusted by moving it according to the sitting height of the person. Further, in the second position, when the neck of the subject is too advanced, the fine adjustment is made to move away from the hair washing ball C. It is also possible to do

Further, when the seat substrate 5 is at the lowest position, the length of the front hanging links 12 and 20 is determined so that the front hanging enters inside the right-angled position. . Further, the drive source for performing the above operation is not limited to the hydraulic cylinder in the embodiment, but may be replaced with another drive source such as an air cylinder or an electric motor.

[0034]

As described above, according to the present invention, since the seat portion in the lowered position is in a substantially horizontal state, the person to be treated can easily get in and out of the seat, and the buttocks do not fall when seated. The operation can be performed in a comfortable position, and the position of the foot can be brought close to the center of gravity by inserting the front drop inward, so that the seating can be performed very easily.

When the seat is raised during washing the hair, the buttocks side of the seat is lowered, so that the subject is stable, and the supine state in a natural posture allows the user to wash the hair in a comfortable posture. In the latter half of the rising process of the part, the hair is moved to the hair-washing ball side, so that it is possible to wash the hair in accordance with the sitting height of the person to be treated without requiring the person to be moved on the chair.
