Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device in which an auxiliary seat is incorporated into a seat that is raised and lowered in a barber chair, and the auxiliary seat is raised and lowered independently of the seat.

[Conventional technology]

In a barber chair, both adults and children sit on the same chair. However, children sit at a lower height than adults. Therefore, when a child is seated on the same seat, the child's head is at a low position relative to the practitioner. For this reason, it is necessary for the practitioner to perform cutting and other hair styling operations while leaning back, which poses a problem in workability. It is especially difficult to work for long periods in this position. For this reason, when a child is being treated, an auxiliary chair is placed on the seat so that the child's head is at approximately the same height as an adult.

[The problem that the idea attempts to solve]

As described above, it is time-consuming to attach the auxiliary chair to the seat of each child to be treated, and a place is required to store the auxiliary chair when not in use.

The purpose of this invention is to provide a cylinder for raising and lowering the auxiliary chair on the seat mounting plate that is raised and lowered by hydraulic operation, so that the auxiliary seat can be raised and lowered independently of the raising and lowering movement of the seat.

[Means to solve the problem]

The present invention has been made to achieve the above object, and a seat mounting plate having a seat is fixed to the upper end of a spindle which is inserted into a cylinder which is rotatably supported on a base and which is movable up and down. In a barber chair that raises and lowers a seat by raising and lowering a spindle using oil pressure sent into a cylinder, an auxiliary seat lifting cylinder is provided on the lower surface of the seat mounting plate, and the upper end of the ram of the cylinder is connected to the seat mounting plate. an auxiliary plate is fixed to the upper end of the ram so as to overlap with the upper surface of the seat mounting plate, and an auxiliary seat is provided on the auxiliary plate;
The gist is that the auxiliary seat part can be moved up and down regardless of the up and down action of the seat part.

[Effect]

The auxiliary seat is equipped with a cylinder for raising and lowering the auxiliary seat of the seat mounting plate, which is raised and lowered by the raising and lowering action of the spindle, so that the auxiliary seat goes up and down along with the raising and lowering of the seat, and can also be raised and lowered independently of the raising and lowering of the seat. do. For this reason, since the raising and lowering of the auxiliary seat and the raising and lowering of the seat are combined, even child patients can position their heads at a height that is easy for the practitioner to work with, and can also be adjusted depending on the work being done. Since the entire body can be raised and lowered in the same way as an adult patient, the treatment can be performed on both adults and children under the same conditions.Furthermore, the above-mentioned operations can be performed only by operating a hydraulic cylinder, improving work efficiency. improves.

〔Example〕

The present invention will be explained below based on the embodiments shown in FIGS. 1 and 2.

In the figure, reference numeral 1 denotes a base, which has a size and shape suitable for a hairdressing chair and can be stably installed on the floor. A cylinder 3 is fixed to the upper end of the auxiliary cylinder 2. Further, a stop plate 8 is provided at the lower end of the auxiliary cylinder 2, and a ram 7 is established on the upper center surface of the stop plate 8. The cylinder 3 and the auxiliary cylinder 2 are arranged in a straight line on the same axis, and a pipe-shaped spindle is fitted into the cylinders 2 and 3, and a pipe-shaped spindle is fitted between the spindle 4 and the cylinder 3, and between the spindle 4 and the cylinder 3. Sealing materials 17 and 19 are respectively arranged between the rams 7 to make the spindle 4 airtight between the cylinders 2 and 2.
3. It is raised by the hydraulic pressure supplied within the cylinder, or lowered by discharging the hydraulic oil.

An upper cover 5 is integrally provided at the upper end of the spindle 3, and a seat mounting plate 6 of a required large shape is provided on the upper part of the spindle 3 through the upper cover 5. Further, a required cushion is provided on the mounting plate 6. Seat part 20
can be installed. A guide rod 15 is provided in the seat mounting plate 6, which is raised and lowered by the raising and lowering movement of the spindle 4, in a vertical direction and protruding from the lower surface of the plate 6.
is provided, and the lower end of this guide rod and the mounting plate 6
A return spring 16 is disposed in between, and the upper end of the guide rod 15 is fixed to an auxiliary plate 12 which can be superimposed on the seat mounting plate.

A cylinder 10 for raising and lowering the auxiliary seat is vertically installed on the lower surface of the seat mounting plate 6 via an upper cover 9. A ram 11 is fitted into the cylinder 10, and the upper end of the ram passes through the seat mounting plate to raise and lower the auxiliary seat. It is fixed to the plate 12. This auxiliary plate 12 is provided with an auxiliary seat 21 that constitutes a part of the seat 20 and is capable of being raised and lowered independently. Further, the upper lid 9 or the cylinder 10 is provided with a hydraulic oil port 13 for supplying or discharging hydraulic oil.
An overflow port 14 is provided at a higher position, and normal hydraulic oil supply and return are performed by selectively switching between supply and oil discharge at the hydraulic oil port 13.
1 reaches the highest position, and when hydraulic oil is supplied, the oil supplied from the hydraulic oil port 13 is sent to the tank from the overflow port 14. In this case, the ram 11 is stopped at the highest position. When this auxiliary plate 12 is raised and lowered by the rise and fall of the ram 11, the guide rod acts to prevent it from rotating.Therefore, even though the auxiliary plate can be moved up and down independently with respect to the seat mounting plate, the rotation movement is limited to the seat mounting plate. This is always done together with the mounting plate.

The seat is raised and lowered by supplying hydraulic oil into the cylinders 2 and 3, which guides it to the ram 7, causing the spindle 7 to rise or fall. Independently from this, when the auxiliary seat is raised and lowered, the ram 11 that feeds oil into the cylinder 10 from the hydraulic oil port 13 rises. At this time, the auxiliary plate fixed to the upper end of the ram moves up while compressing the spring 16. Further, the guide rod 15 prevents the auxiliary plate from pivoting around the ram.

Further, when the auxiliary seat is lowered, the hydraulic oil is discharged from the cylinder 10 to utilize its own weight and the elastic force of the spring 16.

[Effect of idea]

According to the present invention, an auxiliary seat lifting cylinder is provided on the lower surface of the seat mounting plate, and an auxiliary plate is fixed to the upper end of the ram of the cylinder so as to be on the upper surface of the seat mounting plate. The auxiliary seat is provided so that the auxiliary seat can be raised and lowered regardless of whether the seat is raised or lowered, so the auxiliary seat can be raised and lowered automatically, and it is normally a part of the seat. Since it is easy to use, it saves you the trouble of attaching and detaching it each time you use it. Further, since the auxiliary seat can be raised and lowered independently with respect to the seat, and can also be raised and lowered and rotated together with the seat, the auxiliary seat has the advantage of improving workability when treating children as well as when treating adults.
