This invention relates to an improvement of a backrest device for a hairdressing chair.

[Conventional technology]

Conventional chairs equipped with this type of auxiliary backrest include a dental treatment chair described in Japanese Unexamined Patent Publication No. 55-78961, and a headrest device for a dental chair described in Japanese Utility Model Publication No. 60-33960. There is.

In the former, an intermediate backrest is removably inserted into the upper part of a backrest main body that is tiltable with respect to the seat frame, and a headrest is removably inserted into the upper part of the intermediate backrest.

The latter is equipped with a sub-head rest and a sub-back crest/main head rest, and the sub-head rest is held in an expanded/contracted state relative to the sub-back crest/main head rest, and the sub-back crest/main head rest also moves up and down. It is designed so that it can be locked.

[Problem that the invention attempts to solve]

Conventionally, in hairdressing salons, people worked while sitting on chairs in the same position even if their sitting heights were different.

Therefore, there are no problems with work for people who sit at a high height, but there is a disadvantage that it is difficult for people who sit at a low height to work because the backrest and headrest get in the way, and this is especially true for children. Since this can be noticeable, an auxiliary chair was hung on the handrail of the hairdressing chair and the child was made to sit on it.

On the other hand, for women with long hair, their hair gets stuck between the backrest and the back, making it impossible for them to work, so they pull their hair behind the backrest and pull it out, and then pull it out as they work. It gives a bad impression to women.

Therefore, it is proposed to divide the backrest into a main backrest and an auxiliary backrest above it.However, in the former of conventional chairs like this, when the intermediate backrest, which is the auxiliary backrest, is removed, the headrest becomes It has the disadvantage that it cannot be used, it is difficult to perform work on the face, work in a supine position, or it causes pain to the patient.

In addition, the latter allows the sub-headrest and the sub-backrest/main headrest to be raised and lowered, so it can accommodate varying sitting heights to some extent; however, it is not suitable for women with long hair. The traditional flaws remain.

[Means to solve the problem]

The present invention solves the drawbacks of the conventional hairdressing chair, which consists of a backrest with a main backrest and an auxiliary backrest. This is to provide a backrest device for a hairdressing chair, which means includes a backrest body that is tiltable with respect to the seat, and an insertion hole that is inserted into an insertion hole provided on the top surface of the backrest body. equipped with a rod, and
An auxiliary backrest in which a recessed portion approximately the same size as the size of a headrest described later is formed, and an insertion rod that is inserted into an insertion hole provided in each of the auxiliary backrest and the backrest main body, and the insertion rod A headrest having a locking part such as a locking hole formed in the headrest, and a locking fitting such as a locking fitting provided on either the backrest main body or the auxiliary backrest and locking with the locking part in the insertion rod of the headrest. This is accomplished by means of a backrest device for a hairdressing chair.

[Effect]

The hairdressing chair backrest device of the present invention is designed for people with a low sitting height by removing the auxiliary backrest and inserting the insertion rod of the headrest into the insertion hole of the main body of the backrest to lower the height of the backrest. In addition to making the work easier, when working with the patient in a supine position,
The head is supported by a headrest so as not to cause pain to the patient.

Further, the height of the headrest can be adjusted regardless of the presence or absence of the auxiliary backrest, and it can be fixed at the adjusted position by a locking means, and the auxiliary backrest has a recess large enough to accommodate the entire headrest. , so that when the headrest is lowered to its lowest position, the headrest does not protrude beyond the upper surface of the auxiliary backrest, making the work easier.

[Example of idea]

An example of implementation of the present invention will be described below with reference to the drawings.

Reference numeral 1 mainly serves as a backrest, which can be tilted up and down by a connecting rod 15 with respect to an armrest 14 fixed to the seat.

An insertion hole 12 and a headrest guide 13 are provided on the back surface of the backrest main body 1, and an opening piece 9 for opening these onto the upper surface of the backrest main body 1.
is installed.

Reference numeral 2 denotes an auxiliary backrest, which is continuous with the front shape of the backrest main body 1 and has a concave central part on the front surface, and is fixed to the auxiliary backrest 2 so as to be positioned above the backrest main body 1. Insertion rod 3 fixed with metal fitting 11
is removably inserted into the insertion hole 12 through the opening piece 9 of the backrest main body 1.

Further, a supporting frame 6 is fixed to the fixing member 11. The supporting frame 6 has a locking member 7 having a locking pin 7a at one end attached thereto so that the locking pin 7a is biased forward.

Reference numeral 4 denotes a headrest, which is inserted from above into a recessed area in the center of the front surface of the auxiliary backrest 2. A plurality of locking holes 8 are formed in a row on the base plate 10 to which the headrest 4 is attached. The formed insertion rod 5 is fixed.

The insertion rod 5 is inserted through the support frame 6 and into the headrest guide 13 from the opening piece 9 of the backrest main body 1, and is inserted into the locking hole 8 by the force applied to the locking metal fitting 7. , the locking pin 7a is inserted,
The vertical movement of the insertion rod 5 is locked.

Therefore, the auxiliary backrest 2 and the headrest 4 are:
With the locking fitting 7 locking the vertical movement of the insertion rod 5, the insertion rod 5 and the insertion rod 3 are inserted into the headrest guide 13 of the main body 1 of the backrest 1 through the opening piece 9. It can be removed from the attachment hole 12.

Then, by pushing the locking metal fitting 7 against the bias, the locking pin 7a is disengaged from the locking hole 8, the engagement state is released, and the insertion rod 5 is moved to the support frame 6.
It can be extracted from.

The removed headrest 4 can be attached to the backrest main body 1 by inserting the insertion rod 5 through the opening piece 9 and into the headrest guide 13.

In this backrest device for a hairdressing chair, an auxiliary backrest 2 is inserted into the backrest main body 1 when a person with a relatively high sitting height is being treated, and the height of the headrest 4 is adjusted when a person is being treated in a supine position. With this, the back of the head of the patient can be supported.

In addition, when treating people with relatively low sitting heights, children, etc., the auxiliary backrest 2 and headrest 4 are removed from the main body backrest 1, but when treating patients in a supine position, the headrest 4 is used as an auxiliary. By separating from the backrest 2 and inserting it into the backrest main body 1,
It can support the back of the patient's head.

Furthermore, when treating women with long hair, by removing the auxiliary backrest 2 and the headrest 4 from the main backrest 1, the back above the shoulders becomes open.
The treatment can be performed without pulling the hair backwards.

In the above embodiment, the locking fitting 7 of the locking means for adjusting the height of the headrest 4 was provided on the auxiliary backrest 2, but it can be provided on the backrest main body 1 and the auxiliary backrest 2 can be removed. However, the height of the headrest 4 may be adjustable.

[Effects of the invention] As described above, the present invention allows the maximum height of the headrest to be adjusted depending on the presence or absence of the auxiliary backrest, as well as adjusting the vertical movement of the headrest when the auxiliary backrest is attached to the backrest body. The headrest can be freely fixed to the backrest body,
Moreover, since the auxiliary backrest has a recess large enough to accommodate the entire headrest, the headrest does not protrude from the top of the auxiliary backrest when the headrest is lowered to its lowest position. It is something that you have.
