Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hairdressing salon in which a backrest is laid down at the time of washing hair, a subject sitting on this chair is laid down at the back, and the head thereof is placed on a shampoo ball. The present invention relates to a hair-washing chair for washing hair on a shampoo ball.

[0002]

2. Description of the Related Art Conventionally, in a hairdressing salon, a shampoo called back shampoo is performed with the face facing upward, so that the seat of the chair on which the hair washer sits is lifted and the backrest is laid down backward. There was a chair for washing hair. When washing hair in this hair-washing chair, make the back of the chair on which the hair-washer sits face the shampoo ball, raise the seat of the chair, and lay the back on the back to wash the hair. The person's face is facing upward, and the head is positioned on the shampoo ball, and the hair is washed.

[0003]

However, the sitting height of the hair-washer varies depending on the person, and when the head is to be positioned on the shampoo ball as described above,
A person with a high sitting height has his head too far behind the shampoo ball, and a person with a low sitting height cannot reach the shampoo ball. Therefore, the shampoo needs to move his buttocks back and forth to position his head approximately in the center of the shampoo ball. Such movement of the buttocks during hair washing is not only a great hassle for hair washers, but
Since the shampoo ball is on the back of the head, it cannot be seen, and there is a drawback that it is difficult to bring the head to the center of the shampoo ball.

In order to eliminate the above-mentioned drawbacks when washing hair with a conventional hair-washing chair, the present invention raises the chair seat portion and, when the backrest is laid down backward, at least near the end of the rise. By moving the chair seat rearward and controlling the reclining angle of the backrest to the rear, the degree of rise of the chair seat is adjusted to adjust the distance between the upper end of the backrest and the shampoo ball, and to wash the hair. The head of the shampoo can be easily positioned in the center of the shampoo ball and the neck of the shampoo can be prevented from being unnaturally bent so that the shampoo does not have to shift the buttocks. An object of the present invention is to provide a hair-washing chair that can wash hair in a comfortable posture.

[0005]

SUMMARY OF THE INVENTION The hair-washing chair of the present invention is intended to achieve the above-mentioned object. The means is to use a frame mounted on a base fixed to the floor and a chair for the chair. A seat substrate fixed to the bottom surface of the seat, a backrest substrate mounted so as to be able to lie down on the seat substrate, and a first shaft supported in parallel between the frame and the seat substrate. First and second rotating arms, a driving means such as a cylinder arranged between the second rotating arm and the base, one end thereof is pivotally supported by the seat substrate, and a substantially intermediate portion is provided at a substantially intermediate portion. A character-shaped cam hole is formed through it,
Further, a cam arm penetrating the cam hole is provided with a control arm pivotally supported by the first rotating arm, and a connecting arm pivotally supported between the other end of the control arm and the control support board. It was done.

Further, according to the present invention, the front end of the chair is rotated upward by interlocking with the reclining of the backrest.
It is desirable to have the entire body in a sleeping state.

[0007]

In the hair-washing chair of the present invention, the rotating arm is rotated upward about the shaft fulcrum of the base by the operation of the power means, so that the base plate of the chair seat is raised. Further, when the rotating arm rotates, the rotating tip of the rotating arm draws an arc centered on the shaft fulcrum of the base, and thus moves upward,
The distance moved to the rear increases. Then, when the control arm connected to the rotation arm moves together with the rotation arm by the rotation of the rotation arm, the angle of the control arm is controlled by the cam hole fitted to the shaft of the rotation arm. To be done
The backrest board that is pivotally supported on the chair seat and can be laid down,
By the control of the control arm, the pushing distance of the connecting arm connected thereto changes, and the reclining angle of the backrest changes so that the shampoo ball is located on the extension line thereof.

Moreover, as the substrate of the chair seat portion moves backward so as to approach the shampoo ball, the upper end of the backrest is lifted as the chair seat portion rises, together with the control of the angle of the backrest substrate. It will move to approach the extension of the angle to the shampoo ball. By controlling the operation end position of the power means by controlling the rising height of the chair seat portion, the distance between the tip of the backrest and the shampoo ball can be increased or decreased while the backrest is positioned on the extension line to the shampoo ball. It is possible to correspond to the sitting height of the person.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a first embodiment of the present invention will be described with reference to FIGS.
Will be described. Reference numeral 1 is a base installed on the floor of a hairdressing salon, and a frame 2 provided on the base 1 is provided with two supporting shafts 3 and 4 for rotating a first rotating arm 5 and a second rotating arm 6. Is pivotally supported at one end thereof, and the other ends of the first rotating arm 5 and the second rotating arm 6 are parallel to the support shafts 3 and 4, and support shafts 7 and 8 having the same intervals as the support shafts 3 and 4. Is pivotally supported on the seat substrate 9.

The other end of the hydraulic cylinder 22 whose ram is pivotally supported by the second rotating arm 6 is attached to the base 1.
Due to the extension, the second rotating arm 6 makes an arc motion about the support shaft 4. The first rotating arm 5 is rotated by the second rotating arm 6 and the support shafts 3, 4, 7, and 8 while keeping parallel to the second rotating arm 6, and is supported by the support shafts 7 and 8. The seat substrate 9 that is also lifted by the rotation of the first rotating arm 5 and the second rotating arm 6 without changing the angle with the first base 1.

[0011] supporting shaft 8 for supporting the said second pivot arm 6 and the seat substrate 9, one end of the control arm 10 is pivotally supported,
At the other end of the control arm 10, a connecting arm 11 is attached to the spindle 1.
It is pivoted at 2. On the other hand, in the vicinity of the rear end of the seat substrate 9, the support shaft 23 of the support plate 13 fixed to the seat substrate 9 is provided.
The arm portion 16a of the backrest base plate 16 in the backrest 15 is rotatably supported by the backrest 15, and the backrest 15 pivots rearward with respect to the seat base substrate 9 about the support shaft 14 and can be laid down. ing.

One end of the connecting arm 11 is connected to the other arm portion 16b of the backrest board 16 of the backrest 15, and the backrest board 16 is laid down backward by the operation of the connection arm 11. Further, the control arm 10 is provided with a V-shaped cam hole 10a.
The cam shaft 17 that is inserted into the shaft hole 5a is inserted into the shaft hole 5a of the first rotating arm 5, and therefore the cam hole 10a is the first hole.
It is guided by the cam shaft 17 inserted into the shaft hole 5a of the rotating arm 5.

In the extension process, the hydraulic cylinder 22 is extended so that the line X connecting the support shafts 3 and 7 of the first rotating arm 5 shown in FIG. 1 reaches the line X ₁ in the figure. Stop at that position, and the next operation instruction is X ₂ in sequence,
It extends so as to rotate to X ₃ and X ₄ .
At the front end of the seat portion 18 provided on the seat portion substrate 9, a front drop 19 for supporting the back surface of the calf of the hair washer seated on the seat portion 18 is pivotally supported by the support shaft 20, and the front drop 19 and the backrest are supported. Interlocking arm 2 with other arm portion 16c of substrate 16
When the backrest 15 is laid down to the rear, the lower end of the front drip 19 rotates forward and upward to approach a horizontal state.

Next, the operation of the hair-washing chair will be described. First, the hydraulic cylinder 22 is commanded by an external command.
Is a line X connecting the support shafts 3 and 7 of the first rotating arm 5 in FIG.
Is extended to rotate to line X _{1 in} FIG. As a result, the first rotating arm 5 and the second rotating arm 6 rotate about the support shafts 3 and 4 up to the line X ₁ and a line parallel thereto, so that the line connecting the support shafts 7 and 8 is connected. Rises in parallel with the support shafts 3 and 4, so that the seat substrate 9 rises while maintaining an angle with respect to the base 1 (when parallel, it remains parallel).

Since the line X is substantially horizontal in the first stage of this ascent, the backward movement distance of the seat substrate 9 is increased by the rotation of the first rotation arm 5 to reach the line X _1. Is extremely small. On the other hand, between the line X ₁ and the line X ₄ in FIG. 3, the angle of the first pivot arm 5 approaches a vertical angle, and the rearward movement distance of the seat substrate 9 gradually increases. It is a thing. When the first rotating arm 5 rotates to the angle of the line X ₁ , the cam hole 10a of the control arm 10 pivotally supported by the second rotating arm 6 by the support shaft 8 is attached to the first rotating arm 5. It is guided by the fixed cam shaft 17 and shown in FIG.
It becomes the state of.

Therefore, the control arm 10 is in the state shown in the figure, and the support shaft 12 operates the connecting arm 11 so that the support shaft 14 of the connecting arm 11 causes the arm portion 16 of the backrest board 16.
Since b is pulled, the backrest board 16 pivots rearward, and the backrest 15 reclines rearward. The reclining angle of the backrest 15 at this time is slightly larger than the horizontal angle, but there is a shampoo ball on the extension line. And
Corresponding to the rearward lying of the backrest 15, the interlocking arm 21 pushes the front drip 19 and rotates it slightly forward and upward, lifting the legs when the backrest 15 is lying down, and comforting the hair-washer. It is a posture.

In this way, from the state of FIG. 2 in which the first rotating arm 5 has been rotated up to the angle of the line X ₁ , by an external command,
When we reach line X ₄ from line X ₁ through lines X ₂ and X ₃ ,
As shown in FIG. 3, the seat substrate 9 rises in the same manner as described above, but at this time, as described above, the seat substrate 9 at that time is raised.
The receding distance with respect to the ascending distance is increased more than before. At the same time, the control arm 10 has its cam hole 10
By the action of the cam shaft 17 with respect to a, the angle becomes as shown in the figure, and the arm part 16b of the backrest board 16 is pulled by the connecting arm 11 to further recede the backrest 15 to the state shown in the figure.

At this time, the upper end of the backrest 15 is closer to the shampoo ball than in the state of FIG. 2 because the seat substrate 9 is retracted further than in the state of FIG. 2 as described above. Becomes Then, the interlocking arm 21 further raises the lower end of the front drip 19 in accordance with the size of the reclining of the backrest 15, and lifts its legs in proportion to the size of the reclining of the upper half of the body of the hair-washer. Make sure you have a comfortable posture.

Lines X ₂ and X ₃ before the state shown in FIG.
When the first rotation arm 5 is instructed to stop at the angle of, the support shafts 7, 8, 1 are moved at the positions shown by the two-dot chain line in FIG.
2 and 14 stop, whereby the upper end of the backrest 15 is located at the position indicated by the chain double-dashed line in the figure, which is an intermediate state between FIG. 2 and FIG. Thus, the seat portion 18 provided on the seat substrate 9
At the same time as they retreat toward the shampoo ball,
The backrest 15 has its upper end brought closer to the shampoo ball while increasing its prone angle.

In this way, the backrest 15 can be positioned on the change in the distance from the rear end of the seat 18 to the shampoo ball and on the radiation passing through the front end of the shampoo ball. Therefore, for a person with a high sitting height, the first rotating arm 5 is rotated to the line X ₁ to bring it to the state of FIG. 2, and for a person with a low sitting height, to the line X _{4 of} FIG. In contrast, the hair washer's head should be positioned at the center of the shampoo ball by rotating it to the intermediate lines X ₃ and X ₄ to obtain the state of the chain double-dashed line in FIG. 3 and FIG. Is something that can be done.

In the second embodiment of the present invention shown in FIGS. 6 to 8, the position of the cam shaft 17 provided on the first rotating arm 5 of the first embodiment is changed to change the position of the cam hole 10a. The shape is a V-shape close to a straight line, and other configurations are the same as those in the previous embodiment. Therefore, in the drawings, the same parts as those in the previous embodiment are designated by the same reference numerals, and the configuration, and The operation and action and effect thereof are the same as those of the previous embodiment, and the explanation thereof will be omitted.

[0022]

As described above, according to the present invention, when the seat substrate is raised by the power means, the backrest collapses, and the tip of the backrest comes closest to the shampoo ball while the seat substrate is being raised. At the most raised position, the tip of the backrest is separated from the shampoo ball, which is different from the conventional approach where the tip of the backrest approaches the shampoo ball in proportion to the rise.

Accordingly, the rise of the base plate of the seat portion is adjusted by controlling the operation end position of the power means, and the distance between the chair seat portion and the shampoo ball is changed, so that the height of the hair washer can be adjusted. At this time, the backrest changes the prone angle with respect to the chair seat so that the shampoo ball is located on the extension line, so that the neck does not have to be in an unnatural posture. Therefore, it is possible to eliminate the need for the hair washing person to move the hips on the seat part and perform the unpleasant motion of adjusting the head to the position of the shampoo ball depending on the height of the sitting position.

Since only one operation for controlling the height of the base plate of the chair seat portion at the operation end position of the power means is sufficient for the operation, the seat portion retracted position and the backrest inclination angle are set to two.
It is not necessary to adjust it with one hand, and not only the handling operation is simple, but also the mechanism is simplified, breakdowns etc. are reduced, maintenance can be facilitated and the price is kept low. is there.
