Description

[Detailed Description of the Invention] The present invention provides a so-called back seat, that is, a chair.
The mechanism was developed to adapt to shampooing by rotating the chair 180 degrees, then raising the chair, tilting the backrest, and placing the customer in a supine position, with the nape of the customer's neck resting on the neck of the shampoo bowl. The present invention relates to a beauty chair.

The above-mentioned backrest is performed to prevent the customer from bending forward forcibly, that is, to allow the customer to lie comfortably on his or her back. was hinged directly to the rear of the underseat, and the seat could be tilted and raised using the hinge as a fulcrum. However, with this type of hairdressing chair, when the backrest is tilted, the technician must support the backrest with his hands, and when the backrest is tilted, the back of the customer's clothes are pulled, causing discomfort to the customer. There were some cases where there were some problems.

The present invention has been developed to eliminate the above-mentioned disadvantages, and its purpose is to allow the customer to move into a supine position without the back of his clothes being stretched when the backrest is tilted, and thus without causing any discomfort to the customer. Our goal is to provide you with the best hairdressing chair possible.

Another object of the present invention is to provide a hairdressing chair that can softly fit the nape of a customer's neck to the neck of a shampoo bowl, and another object of the present invention is to provide a hairdressing chair that can gently fit the nape of a customer's neck to the neck of a shampoo bowl. We provide beauty chairs.

Next, an embodiment of the present invention capable of achieving the above object will be described in detail with reference to the accompanying drawings.

1 is a base plate; 2 is a pair of rising plates fixed to the base plate 1 facing each other; 3 is a hydraulic cylinder rotatably provided via a shaft 4 mounted between the rising plates 2; 3a; is the hydraulic cylinder plunger, 5
6 indicates an under seat, 6 indicates two hanging plates fixed oppositely to each other at the bottom of the under seat 5, 7 and 8 indicate parallel operating plates, and one end of the flat operating plates 7 and 8 connects the shafts 9 and 10. The lower end of the hanging plate 6 is rotatably connected to the upper part of the upright plate 2 via shafts 11 and 12 at the other end thereof. Further, the tip of the plunger 3a described above is rotatably mounted approximately at the longitudinal center of the parallel operating plate 7 via a shaft 13.

14 is a backrest, 15 is an armrest mounting plate having an armrest 15a, 16 is a front sag, and at the bottom of both sides of the backrest 14 are brackets 1.
4a and the protruding piece 14b are fixed, and the armrest mounting plate 15 is fixed to an underseat substrate (not shown). Also armrest mounting plate 1
A protrusion 15b is also fixed to the protrusion 15b, and the bracket 14a of the backrest 14 attached to the protrusion 15b is attached to the shaft 1.
It is rotatably pivoted via 7.

Reference numeral 18 indicates an operating swash plate, 19 indicates a longitudinally moving plate, and 20 indicates an angle plate. is the protruding piece 1 of the backrest 14 mentioned above.
It is rotatably pivotally connected to a shaft 22 fixed to 4b. One end of the angle plate 20 is the under seat 5
It is rotatably pivoted to the front part of an undersheet substrate (not shown) via a shaft 23, and a front sag 16 is fixed to the other end. Further, the front part of the back-and-forth moving plate 19 is rotatably attached to the angle plate 20 via a shaft 24, and the rear part is attached to the aforementioned protrusion 14b via the shaft 24.
It is rotatably pivoted via 5.

Next, to explain its function, when the backrest 14 is upright and the front sag 16 is hanging down as shown in FIG.
As the plunger 3a is driven and the plunger 3a protrudes, the parallel operating plate 7 rotates counterclockwise about the shaft 9, and the parallel operating plate 8 also moves parallel to the parallel operating plate 7 using the shaft 10 as a fulcrum. Depending on the movement, the hanging plate 6, under seat 5, armrest 1
5a is pushed forward while rising without changing its posture.

Therefore, the longitudinal movement plate 19 that is pivotally supported by the angle plate 20 that is pivotally connected to the underseat 5 moves forward, and the protrusion that is connected to the rear end of the longitudinal movement plate 19 via the shaft 25 moves forward. The piece 14b rotates counterclockwise, and the backrest 14 to which the protruding piece 14b is fixed tilts rearward about the shaft 17 as a fulcrum.

Further, as the forward and backward movement plate 19 moves forward, the angle plate 20 rotates counterclockwise about the shaft 23, and the front droop 16, which has been in a drooping state, is raised.

On the other hand, with the counterclockwise rotation of the parallel operating plate 7,
The operating swash plate 18, which is pivotally attached to the shaft 21, moves forward while rotating counterclockwise, and regulates the rotational position of the protrusion 14b, that is, the tilted position of the backrest 14.

By further retracting the plunger 3a, each part operates in the opposite manner to the above and returns to its original position.

Since the present invention is constructed as described above, the underseat moves forward without changing its posture at the same time as the backrest is tilted, so that the back of the customer's clothes will not be unilaterally pulled as if only the backrest were to fall. In addition, by collapsing the backrest in sync with the upward movement of the underseat, it is possible to softly fit the neck of the shampoo bowl, and in this case, the front of the seat will naturally rise, resulting in an even more comfortable posture. It has the following effects.

Claims (1)

[Scope of Claims] 1. A pair of opposing rising plates having one end of each fixed to a base plate, a hydraulic cylinder having one end pivotally connected to the lower part between the pair of rising plates, and one end of each rising plate to the lower part of the underseat. an underseat position in which both ends are pivotally connected to each other end of a pair of opposing hanging plates to which are fixed and each other end of the pair of rising plates, and a plunger of the hydraulic cylinder is pivotally connected to one end; a pair of parallel operating plates that raise and lower and move forward and backward without changing the position; a backrest whose lower part is pivoted to an armrest fixed to the rear of the underseat; and an angle plate whose one end is pivoted to the front of the underseat. The front sag is fixed to the end, and both ends are pivotally connected to the protrusion fixed to the lower part of the backrest and the angle plate, and the backrest and the front sag are moved back and forth to raise and lower, respectively, as the underseat moves up and down and moves forward and backward.
