According to the present invention, a shampoo bowl is fixed to a base of an elevating device and a chair is attached to the base in a rotatable manner.
Hereinafter, a first embodiment of a barber or beauty salon chair according to the present invention will be described with reference to drawings.
Numeral 1 denotes an elevating device with a known structure in which a base 2 is lifted and lowered in a horizontal condition by oil supply or oil removal with respect to a hydraulic cylinder 11. Numeral 3 denotes a shampoo bowl attached to one end of the base 2, which is moved up and down by the elevating means 1 while maintaining a horizontal condition. A hose 31 for discharging shampoo water flowing in the shampoo bowl 3 or a water-supply pipe 33 for supplying a showerhead 32 with warm water is provided inside the elevating device 1 and equipped at a lower position compared to the elevating device 1.
A rotatable neck receiver 34 for supporting the neck rear region of the customer at the time of shampoo and a rotatable occipital region receiver 35 for receiving two regions of the occipital region of the customer are provided inside the shampoo bowl 3. Since the neck receiver 34 and the occipital region receiver 35 support the neck rest region and the occipital region of the customer, the chair allows the customer to maintain a comfortable condition without imposing a burden.
Numeral 4 denotes a chair composed of a bed-shaped portion 41 which receives the leg below the hip of the customer in a horizontal condition and a backrest 42 which is rotatably supported by a shaft at an upper end side of the bed-shaped portion 41 and allows a recline angle to be changed by oil supply or oil removal with respect to a hydraulic cylinder 43. A shaft rod 41b, that is supported by the shaft receiver 21 with the bearing attached to the base 2, is arranged in a standing manner to a pivotal motion board 41a at a rear face of the bed-shaped portion 41.
A rotation supporting board 44, that is fixed to the pivotal motion board 41a, is fixed to a side of a rear face of the pivotal motion board 41 while a fixation supporting board 22 is fixed to a side of a top face of the base 2. Outer circumferential portions of the rotation supporting board 44 and the fixation supporting board 22 are provided with a rotation holding means 23, that is composed of ring-shaped recesses for receiving a one-sided load applied to the chair and a ball intervened between the recesses.
Furthermore, the rotation supporting board 44 is provided with a locking means 45 composed of a spring 45a and a ball 45b that borders on an arc-shaped guiding recess 22a formed to the fixation supporting board 22. Both ends of the arc of the guiding recess 22a are formed deeper than a recess depth of the others, resulting in locking recesses. One locking recess in the guiding recess 22a is formed in a position where the ball 45b of the locking means 45 enters when the chair 41 is set in a rotation position in a direction parallel to the base 2, that is, a position shown in
As a result, the chair 4 enters a locked condition in two positions for a shampoo treatment and other treatments (a position where the chair is rotated by 60 degrees from a position for a shampoo treatment) since the ball 45b enters in the locking recess. When a strong rotation force is applied to the chair 4 in the above locked position, the ball 45b gets out of the locking recess, shifts along the guiding recess, and enters the other locking recess to set a locked condition. At the time of rotation of the chair 4, the shaft rod 41b, the shaft receiver 21, and the rotation holding means 23 achieve smooth rotation. The above rotation angle from the shampoo position to the other position is not limited to 60 degrees.
The backrest 42, which is attached to the chair 41 in a manner to allow a recline angle to be adjustable, is provided integrally with arm receivers 42a formed to overhang in right and left directions. These arm receivers 42a slightly increase in vertical height as they extend. Lower ends of the arm receivers 42a extend up to both end surfaces of the bed-shaped portion 41 so as to be formed longer than a portion for receiving the back region of the customer. Therefore, each of the arm receivers 42a is in a form capable of supporting the whole arm of the customer in a lying condition with the backrest 42 deeply reclined. A front end portion of the backrest 42 (a side of the cephalic region of the lying customer) is provided with an installation hole for attaching a headrest 5 shown in
The following explains what posture the barber and beauty salon chair is set in to shampoo the hair of the customer in a lying condition.
First, the practitioner lets the customer sit on the bed-shaped portion 41 of the chair 4 in a condition where the backrest 42 shown in
The customer in a lying posture is shifted in a manner to place his/her rear neck region on the neck receiver 34 of the shampoo bowl 3, so that his/her occipital region are supported by the occipital region receiver 35. The practitioner shampoos the customer's hair in this condition and sets the backrest 42 upright after the shampoo. When the treatment is completed after the shampoo only, the practitioner lets the customer get off the bed-shaped portion 41 and the shampoo treatment is completed.
After the shampoo treatment, when the customer undergoes other treatment such as a facial treatment, a beauty treatment, a massage, or the like, the practitioner pushes the bed-shaped portion 41 or the backrest 42 to rotate the chair 4, and thus the chair 4 is locked in a rotation angle of 60 degrees and enters a locked condition (see
In the meantime, in a lying condition, the arms of the customer are held with the arm receivers 42a, thereby allowing the customer to undergo the treatment in a stable condition.
After completion of the treatment, the backrest 42 is set upright and the practitioner lets the customer get off the bed-shaped portion 41 and rotates the chair 4 in a side of the shampoo bowl 3 again to prepare the next treatment, thereby completing the whole operation. It is to be noted that up and down motion of the chair 4 was not described in the above explanation for the operation but it goes without saying that a height of the chair 4 is adjustable according to a height of the customer.
In the embodiment described above, the customer sits on or gets off the chair 4 from the side surface of the bed-shaped portion 41. Thus, it is very difficult for customers of short stature such as women or children to get on or off the chair 4 since they have to open their legs widely to straddle the chair 4. There has arisen such a problem especially for women in a skirt that they get embarrassed when they open their legs widely.
Therefore, at a seat portion 41c on which the customer's hip region is placed and the front drooping portion 41d on which the customer's calves are placed in the bed-shaped portion 41 shown in
Hereinafter, the second embodiment will be described in detail with reference to
Numeral 6 denotes a front drooping cylinder supported at one end by a shaft to a bed attaching table 46 for attaching the bed-shaped portion 41, and supported at the other end by a shaft to a pivotal motion board 47 attached to be pivotable at the front end portion of the bed attaching table 46.
Furthermore, a sliding means 48 is intervened between the pivotal motion board 47 and the front drooping board 41e. One example of the sliding means 48 is described with reference to
Next, operation based on the above structure will be described. In
Since the front drooping portion 41d and the seat portion 41c are integrated, a pulling force (force in a right direction in
The customer takes a seat or gets off from a seated condition where the front drooping portion 41d is displaced in a vertical direction, so that the customer can take a seat or gets off by taking the same action applied to a regular chair, thereby making it easy to get on or off the chair.
It is to be noted that a case of the chair in which the seat portion 41c and the front drooping portion 41d are integrated is described in the embodiment described above, but the chair in which the seat portion 41c and the front drooping portion 41d are separated produces the same effects in that the customer can get on or off the chair 4 very easily.
Furthermore, a case where the backrest 42 and the front drooping portion 41d are operated separately was explained in the embodiment described above. However, the backrest 42 and the front drooping portion 41e can be displaced in a horizontal or vertical direction in synchronization with each other by bringing the backrest cylinder 43 into synchronization with the front drooping cylinder 6 electrically.
The rotation device of the chair 41 in the first embodiment described above is structured in a manner to lock the chair 41 in two positions, the shampoo position and the position rotated by an angle of 60 degrees from the shampoo position. However, it is desired to lock the chair 41 at a desired angle position other than these two positions depending on the type of treatment.
Thus, a structure to lock the chair 41 at a desired angle position other than the above two positions will be described with reference to
This embodiment is composed of a locking means 7 including a hydraulic cylinder 7b having a piston 7a attached to a concave portion 44a formed to one portion of the outer circumference of the rotation supporting board 44 and a hydraulic device 7c for supplying oil to the hydraulic cylinder 7a. Furthermore, abutment surfaces 44b, 22b in a curved form are formed to outer surfaces of the rotation supporting board 44 and the fixation supporting board 22 in positions facing the front end of the piston 7.
With a locking means 6 structured in the above manner, where the practitioner rotates the chair 41 up to a position allowing him or her to perform a treatment easily, the hydraulic device 7c supplies pressurized oil into the piston 7b to move the piston 7a with hydraulic pressure in a discharge direction and a front end portion of the piston 7a is brought in pressurized contact with the abutment surfaces 44b, 22b, thereby leading the rotation supporting board 44 into a locked condition with respect to the fixation supporting board 22. In this manner, the chair 41 can be locked in a desired angle position other than the above two positions.
