Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in hairdressing salons, and is used to protect the recipient's hair when cutting, setting, blow-drying, shaping, curling, etc. This invention relates to an improvement of a hairdressing chair on which a person can sit, whose seat part can be raised and lowered, and whose backrest can be raised and lowered.

[Conventional technology]

In some conventional hairdressing chairs of this type, the seat is raised and lowered and the backrest is raised and lowered independently using power such as air or hydraulic power.

However, in such hairdressing chairs, when the backrest is raised and lowered, unless the seat is intentionally raised or lowered, the height of the seat remains the same and only the backrest is raised or lowered. be.

[Problem to be solved by the invention]

In the conventional hairdressing chair as described above, the height of the seat when lowered must be low so that the patient can easily sit on the seat.

In addition, when the backrest is laid down for a lift or facial, the height of the patient's head needs to be in a fairly high position, and this position is different from the seat when lowered previously. In a hairdressing chair in which the undulation of the backrest is not linked to the height of the seat, the lifting stroke of the seat is extremely long.

Such a long stroke cannot generally be formed, and the seat cannot rise to the above-mentioned height, making it difficult for an operator to perform the work.

[Purpose of the invention]

The present invention uses two cylinders provided between the base and the seat to adjust the height of only the seat (first adjustment), and to change the undulation of the backrest as the seat moves up and down. (Second adjustment) The present invention aims to provide a hairdressing chair equipped with means for performing a combination adjustment (third adjustment) of the first adjustment and the second adjustment.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a first cylinder provided on a base, and a second cylinder attached to the upper end of a ram that is raised and lowered by the first cylinder, A seat is attached to the upper end of the ram of the second cylinder, and a rotating plate to which a backrest is attached is pivotally supported at the rear end of the seat.
A backrest undulation rod is provided between the second cylinder and the backrest undulation rod, and the backrest undulation rod is configured to rotate the rotating plate in the direction in which the backrest is tilted as the ram of the second cylinder rises. This is a characteristic feature.

[Effect]

In the hairdressing chair of the present invention, by raising and lowering the ram through the operation of the first cylinder, the seat portion can be raised and lowered while the backrest remains upright or down.

The ram is raised and lowered by the operation of the second cylinder, and the seat part is raised and lowered by the raising and lowering of the ram, and the backrest is raised and lowered by the backrest undulation rod whose one end is pivotally supported by the second cylinder. It is designed to be linked.

Furthermore, it is also possible to operate the second cylinder at a predetermined position where the seat is raised or lowered by the operation of the first cylinder, thereby interlocking the seat and the backrest from the predetermined position.

Therefore, the position of the patient's head does not change significantly due to the movement of the backrest and the seat.

〔Example〕

Next, an example of implementation of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a base installed on the floor, and a first cylinder 2 is attached to this base, and by injecting pressure such as compressed air or hydraulic pressure into this cylinder 2,
That ram 3 rises.

A bracket 4 is attached to the upper end of this ram 3, and a second cylinder 5 is attached to this bracket 4, and by injecting the same pressure into this cylinder 5, the ram 6 is raised. However, when the pressure is released, the spring 8 installed between the pin 7 of the ram 6 and the lower end of the cylinder 5 causes the ram 6 to
is pulled, and the ram 6 descends.

A bracket 10 supporting the seat 9 is attached to the upper end of the ram 6, and a rotating plate 13 is rotatable by a pivot 14 on an arm receiver 12 to which an armrest 11 is attached and fixed to the seat 9. Supported by
A backrest 15 is fixedly attached to this rotating plate 13.

The backrest undulating rod 17, which is pivotally connected to the pivot 16 of the rotating plate 13, is connected to the bracket 4 by the pivot 18.
It is pivoted to.

The other end of the connecting rod 20, which is connected to the front flap 22 which is pivotally connected to the front end of the seat portion 9 by a pivot 19, is pivotally connected to the pivot 21 of the backrest undulation rod 17.

In this hairdressing chair, when pressure is injected into the second cylinder 5 and the ram 6 rises, the seat 9 also rises together with it.

However, since the backrest undulating rod 17 which is pivotally connected to the rotating plate 13 which is pivotally connected to the seat portion 9 is pivotally connected to the bracket 4, the rotating plate 13 is connected to the backrest undulating rod 1.
7, the seat portion 9 rotates about the pivot 14, and the backrest 15 is placed in a prone state as shown in FIG.

At this time, the rotation of the rotating plate 13 pushes the connecting rod 20, which pushes the front flap 22 and rotates its lower end forward and upward. As a result, the patient sitting on the seat 9 is placed in a supine position.

In other words, since the patient shifts to this supine posture by raising the seat 9, the position of the head of the patient does not fall, unlike when the backrest is simply laid down behind the seat. The height of the head is almost the same as when sitting on the 9.

Conversely, when the pressure is discharged from the second cylinder 5, the ram 6 descends due to the bias of the spring 8, so the seat 9 also descends, and the backrest lever 17 and the rotating plate 1
3 makes the backrest 15 stand up and the front flap 22 hangs down by performing the opposite operation to the above.

Therefore, the patient who was in the supine position is returned to the sitting position, but the height of the patient's head does not increase at that time, and the head position remains at almost the same height as when in the supine position. drooping

On the other hand, when pressure is injected into the first cylinder 2 and the ram 3 rises, the bracket 4 at the upper end of the ram 3 and the second cylinder 5 attached to it
is raised.

Therefore, depending on whether pressure is injected into the second cylinder 5 or not, the patient is raised in a supine position or in a sitting position.

Further, when the pressure is discharged from the first cylinder 2, the ram 3 and the bracket 4 are lowered, and the patient is lowered into a supine or seated position.

〔Effect of the invention〕

In conventional beauty and beauty chairs, when a person is moved from a sitting position to a supine position, the height of the patient's waist remains the same, but the head is tilted backwards, so the height of the patient's head is lowered.

Therefore, while the height for raising and lowering the seat was sufficient in the sitting position, it becomes insufficient when shifting to the supine position, but in the present invention, the height of the backrest is lowered by raising the seat. Therefore, the height of the head will hardly change.

Therefore, even though the lowest position of the seat is low enough for the patient to sit down, the position of the head in the supine position can be set to a sufficient height.

In the present invention, by combining two cylinders, it is possible to adjust only the height of the seat, to adjust the height position of the seat in conjunction with the ups and downs of the backrest, and to adjust the combination of the two adjustments, etc. It has the effect of improving work efficiency regardless of the body shape of the worker or the person to be treated.

Therefore, regardless of the sitting height of the patient or the height of the worker, the worker can set the hair,
The head position of the person to be treated is maintained at a height that makes it easy to perform hair washing, hair wrapping, etc., which improves work efficiency and reduces fatigue.
