Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hairdressing chair whose seat can be raised and lowered and whose backrest can be folded down when washing hair or the like.

[Conventional technology]

Conventionally, in a hairdressing chair in which the seat can be raised and lowered and the backrest can be raised and lowered, the driving for raising and lowering the seat and the raising and lowering of the backrest are driven by separate motors or two drives such as cylinders. It was done by a device.

[Problems to be Solved by the Invention] Therefore, the lower part of the hairdressing and beauty chair that accommodates the two drive devices has become large, which has worsened the appearance of the hairdresser and beauty chair.

In addition, drive devices such as motors and cylinders are expensive, and since two of these are used, the hairdressing chair ends up being expensive.

[Purpose of invention]

This invention focuses on rotating the seat 180 degrees when washing hair at a hair salon.The rotation fixes the height of the seat high, and the subsequent movement of the cylinder increases the height of the seat. By tilting the backrest down, it is possible to raise and lower the seat and raise and lower the backrest using a single cylinder, simplifying the mechanism and making the lower part of the chair smarter, while also being inexpensive. The purpose is to provide beauty chairs.

[Means to solve the problem]

The present invention relates to means for a hairdressing chair to achieve the above-mentioned object, and includes an inner cylinder in which either a cylinder or a ram is fixed to a base, and which moves up and down as the cylinder expands and contracts, and a side surface of the inner cylinder. An upright pin slides, and a guide hole is drilled where the pin hits at the upper and lower ends, and an outer cylinder that fits into the inner cylinder and the lower side of the outer cylinder are fixed to the base. a support tube having a support portion bored therein, and a mounting portion rotatably fitted to the upper side of the outer tube and placed on the support portion of the support tube when the outer tube is rotated; The rotary cylinder to which the seat is attached is connected to a backrest part that can be raised and lowered with respect to the seat, and rotates as the rotary cylinder rotates, and as the pin moves up and down. This is done using a hairdressing chair equipped with a rotating ring that moves up and down.

[Example of idea]

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

Reference numeral 1 denotes a base on which a hairdressing chair is installed on the floor, and a mounting plate 3 to which a cylinder 2 is attached is fixed to this base.

This cylinder 2 houses a ram 5 that extends upward when pressure is introduced through the pipe 4, and a top plate 6a of an inner cylinder 6 that is loosely fitted into the cylinder 2 is attached to the top of the ram 5 with bolts 7. A cushion 8 is also attached to the top plate 6a.

An outer cylinder 9 is loosely fitted into the inner cylinder 6, and this outer cylinder 9 is provided with vertical guide holes 9a at a plurality of locations, and these guide holes 9a are provided with screw holes in the inner cylinder 6. A pin 10 screwed onto 6b is inserted therethrough.

Therefore, the outer cylinder 9 can slide up and down with respect to the inner cylinder 6 while being guided by the pin 10 in the guide hole 9a.
Or when the outer cylinder 9 hits the lower end, the outer cylinder 9 touches the inner cylinder 6.
go up and down together.

A rotating cylinder 11 is loosely fitted into the outer cylinder 9, and the top plate 1
A ball bearing 12 is interposed between 1a and the top plate 9b of the outer cylinder 9, and is fixed with a bolt 13.

A seat 14 is fixed to the rotating cylinder 11, and the rotating cylinder 11 and the seat 14 are rotatable relative to the outer cylinder 9 by means of ball bearings 12.

Further, a support cylinder 15 loosely fitted to the outer cylinder 9 is attached to the base 1 by screwing bolts 19 into the mounting plate 3.

This support cylinder 15 is formed with a support part 15a that projects upward and has a horizontal upper surface.A guide hole 15b through which the pin 10 is inserted is formed in the side surface of this support part 15a. By inserting the pin 10, the outer cylinder 9 is prevented from rotating.

A rotary ring 16 is fitted around the plurality of pins 10 so as to be rotatable around the support tube 15.

The rotary cylinder 11 has a support part 1 of the support cylinder 15.
A mounting portion 11b placed on the mounting portion 5a projects downward with its lower surface being horizontal.

Further, a backrest portion 17 is attached to the seat portion 14 so as to be able to rise and fall, and this backrest portion 17
and the rotating ring 16 are connected by a connecting rod 18, and when the seat portion 14 is rotated in the horizontal direction, the backrest portion 17, the connecting rod 18, and the rotating ring 16 also rotate.

At this time, the guide portion 11c provided on the side surface of the mounting portion 11b of the rotating tube 11 rotates together with the rotating tube 11,
It helps the rotation of the connecting rod 18 and rotation ring 16 inserted through the guide portion 11c.

Next, the operation of this hairdressing chair from when the seat portion 14 is in the lowered state as shown in FIGS. 7 and 11 will be described below.

At this time, the seat part 14 is facing leftward as shown in FIG.
As shown in FIG. 7, due to the rotational position of the seat 14, it is located at a different position from the support part 15a of the support cylinder 15, and its lower end surface is lower than the upper end surface of the support part 15a. in position.

The pin 10 is in contact with the upper end of the guide hole 9a of the outer cylinder 9.

In this state, from pipe 4 to cylinder 2
When pressure is injected inside, the ram 5 is pushed by the pressure and rises, so the inner cylinder 6 also rises together with the ram 4.

At this time, since the pin 10 of the inner cylinder 6 is in contact with the upper end of the guide hole 9a of the outer cylinder 9, the outer cylinder 9 also rises as shown in FIG.
1. The seat 14 also rises, and unless the pressure inside the cylinder 2 is relieved, the seat 14 is held in the raised position shown in FIG. 12.

In this way, the seat portion 14 is raised, but at this time, the lower end surface of the mounting portion 11b of the rotary tube 11 is at a position slightly higher than the upper end surface of the support portion 15a of the support tube 15. .

In this state, when the seat 14 is rotated to face the right side as shown in FIG. 13, the rotating cylinder 11 is also attached to the outer cylinder 9 by the ball bearing 12 as shown in The mounting portion 11b rotates against the
moves onto the support portion 15a.

Next, when the pressure inside the cylinder 2 is released as shown in FIG. 10, the ram 5 descends, and the inner cylinder 6 also descends.

However, since the mounting portion 11b of the rotary cylinder 11 is placed on the support portion 15a, the rotary cylinder 11 cannot be lowered, and therefore the outer cylinder 9 is also not lowered.

Therefore, the pin 10 of the inner cylinder 6 is inserted into the guide hole 9.
Since the rotating ring 16 descends by sliding inside a, the rotating ring 16 also descends together.

Therefore, the continuous rod 18 pulls the backrest 17 downward, so that the backrest 17 falls backwards as shown in FIG. 14, and the folding operation is completed.

In order to return from this prone state to the state shown in Figs. 7 and 11, pressure is injected into the cylinder 2 and the 9th
After the backrest 17 is erected as shown in FIGS. 8 and 13, and the seat 14 is rotated to the state shown in FIGS. 8 and 12, the pressure inside the cylinder 2 is released. This can be done in the reverse order.

In the embodiment described above, the cushion 8 has an outer cylinder 9 that is lowered relative to the inner cylinder 6, and both top plates 6a, 1
This is to relieve the shock that 1a comes into contact with.

In contrast to the above-mentioned embodiments, it is also possible to undulate the backrest and the front flap in conjunction with each other, or to replace the raising and lowering of the seat and the undulating of the backrest with the undulations of the backrest and the undulating of the front flap.

Furthermore, it is also possible to use a reciprocating linear motion device such as a rack instead of the cylinder and ram.

[Effect of idea]

As mentioned above, the present invention expands and contracts the cylinder and ram by injecting and discharging pressure into the cylinder,
The seat can be raised and lowered.

In addition, after the seat has been raised and turned 180 degrees, the pressure inside the cylinder is discharged to allow the backrest to lie down, and by reversing this, the backrest can be raised. .

Therefore, one cylinder can perform two types of operations: raising and lowering the seat and raising and lowering the backrest, eliminating the need for separate drive devices in the past, simplifying the mechanism and reducing the number of malfunctions associated with this. At the same time, costs can be reduced by reducing the need for expensive drive devices.
It can be provided at a low price.

Furthermore, since the number of drive devices and connection mechanisms housed in the lower part of the chair between the seat and the base can be reduced, the lower part of the chair can be kept tidy.
