Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electrically driven rotating hairdressing chair.

In barbershops, hair is usually washed and styled after the hair is cut, and the method of washing hair involves the person being styled leaning forward over a shampoo bowl attached to the dressing table, as shown in Figure 7A. There is a back lift method in which the backrest of the chair is tilted backwards as shown in Figure B. For this reason, in barbershops, either pre-washing or shampooing is adopted in advance, and chairs are installed accordingly. Therefore, in barbershops that adopt the pre-washing method, even if a customer requests a hair wash, they have to move a heavy chair, which is almost impossible, and it is difficult to accommodate the customer's request. On the other hand, in barbershops that use the bathing method, pre-washing cannot be performed while sitting on a chair. This is because the distance between the shampoo ball and the chair is determined in advance in the pre-washing method and the back-washing method, and the chair is installed, and the distance differs depending on the method.

In view of this, the present invention allows the chair to be moved back and forth electrically according to the customer's request, and the chair can also be rotated according to the usage to change the distance from the shampoo ball to facilitate pre-washing and back-washing. The present invention will be described below based on the illustrated embodiments.

In the figure, 1 is the main body of the barber chair, and although the detailed mechanism is not shown, the backrest 1A and apron 10 can be tilted freely, the seat 1B can be raised and lowered,
Furthermore, the main body 1 consisting of the backrest, seat, apron, etc. is rotatable relative to the base 2. As with the conventional method, tilting and rotation can be stopped or canceled at any position. Further, the base 2 supporting the main body 1 is automatically moved to the mirror table, that is, the shamp ball B by switching the electric motor for moving the main body 1 on the floor using a foot switch or a manual switch provided on the main body. Move in the direction of approach and separation. This is done by installing a movable trolley 3 at the bottom of a base 2 having the desired shape. I will prepare it. Normally, it is desirable to have at least two or more rollers in order to ensure stability and smooth running of the cart, and any one or two of these rollers are equipped with a built-in electric motor and used as a driving roller to drive the electric motor. so that the roller 4a rotates. In the illustrated embodiment, the rollers are a combination of a long roller and a short roller, but it is also possible to use either one of the rollers.

A thrust bearing B ₁ is installed on the top of the base 2 above.
supports the load applied to the chair through the chair, and allows the seat of the chair to pivot freely, and allows a shaft S, which passes through the base 2 and the movable cart 3 and is fixed to the chair seat, to protrude below the cart; A pulley 5 is fixed to the lower end of this shaft, a belt 8 is stretched between this pulley 5 and a pulley 7 of a turning electric motor 6 provided on the movable cart 3, and the shaft S is rotated by the drive of the electric motor 6. The seat fixed to the upper end of the shaft is rotated by rotating the seat, and the pulley and belt are designed according to the type of belt.
For example, a timing belt, a V-belt, a flat belt, etc. may be used as the belt. It is also possible to use a chain and sprocket wheel type or a gear type in place of this belt. Stopping the rotation of the seat and determining the rotation angle are performed using a striker 9 provided on the shaft S and a plurality of limit switches SW ₁ , SW ₂ arranged along the outer circumferential trajectory of the striker rotation.
...This is specified in SW _o , and an example of this electric circuit is shown in Figure 6. The rotation motor 6 and the driving motor built into the roller 4a (not shown) are stopped by foot switches SWa and SWb protruding from the base 2, but these switches are located on the chair body side. It may also be provided so that it can be operated manually.

When the base configured as described above is moved between the back pump position and the front washing position by the traveling of the moving carriage, rollers 4a and 4b provided on the lower surface of the moving carriage are used.
Although it is possible to move the board directly on the floor, a flat board having a size that spans the moving range l of the moving cart is used to allow smoother movement. Of course, this board 10 is placed at the location where the chair is installed.
Although it is installed on the floor within a movable range, it may also be fixed to the floor. Even if the movable cart 3 is repeatedly moved, the shamp ball B
Guide rails 11 are provided protruding from both sides of the lower surface of the movable trolley so that the movable trolley can move only a predetermined distance and on an accurate trajectory between the fixed position and the fixed position, and the guide wheels 12 are attached to the board 10 so as to be in contact with the guide rails 11. provided. If the roller 4a is a long type, this is positioned outside the roller 4a so as not to hinder the rolling of the roll.

This movable cart moves to a predetermined position using guide rails 11 and guide wheels 12, but in order to stop the chair at a fixed position depending on the purpose, it is provided with a stopper device 13 as shown in FIG. . This stopper device 13 is arranged parallel to the forward and backward direction of the movable cart, and one end is connected to the movable bracket 1.
A rod 1 is mounted on the base plate 10 via a movable bracket 13c, and the other end is mounted on a movable carriage via a movable bracket 13c.
3a, and a sliding body 13d (trunnion mechanical lock) which is fitted into the rod 13a and is slidable.
Even if the trolley shakes vertically and horizontally within the permissible range when moving at points b and 13c, the rod 13a will follow this movement.
The sliding body 13d is fixed to a part of the movable carriage 3 via a bracket 13e, and the sliding body 13d is fixed to a part of the movable carriage 3 via a bracket 13e. ) for holding or releasing the rod.
The tip of the lever 13f is connected to the solenoid 14 installed on the movable cart by a wire or link 15, and only when the solenoid 14 is activated, the lever 13f is pulled to release the rod. When the solenoid is not operating, the rod is held and fixed, and the solenoid 14
The operation of the motor is synchronized with the operation of the traveling electric motor.

According to the present invention, the shaft fixed to the lower end of the seat is passed through the base and the movable trolley on which the base is installed, and this shaft is moved to the back seat position and forward by a rotating electric motor provided on the movable trolley. The chair can be rotated at the hair washing position and automatically turned to face the chair depending on the purpose, and any of the rollers installed at the bottom of the movable trolley have a built-in traveling electric motor, making it easy and quick to move the chair. , furthermore, a rod disposed in the forward and backward direction of the movable trolley, and a rod fitted into this rod,
There is an advantage that the moving carriage can be reliably stopped at a fixed position because the gripping and releasing of the rod of the grippable sliding body fixed to the movable carriage is synchronized with the drive of the traveling electric motor.
