Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a turning movement stopping device for a hairdressing chair that moves and turns electrically or manually.

In barbershops, hair is usually washed and styled after a haircut, and the method of hairwashing is for the hairdresser to lean forward over a shampoo bowl attached to a dressing table, as shown in Figure 7A. There are two methods: a pre-washing method, and a back-washing method, in which the backrest of the chair is tilted backwards, as shown in FIG. For this reason, in barbershops, either pre-washing or shampooing is used in advance, and chairs are arranged and fixed accordingly. Therefore, in barbershops that adopt the pre-washing method, even if a customer requests a hair wash, it is difficult to move the heavy chair easily, and it is difficult to accommodate the customer's request. In barbershops that use the shampoo method, pre-washing cannot be performed while sitting on a chair. This is because the chair is installed with the distance between the shampoo ball and the chair determined in advance for the pre-wash method and the back shampoo method, and the distance between the shampoo ball and the chair differs depending on the method.

Therefore, the chair can be moved back and forth electrically or manually according to the customer's request, and after stopping at a fixed position, the chair can also be rotated according to the usage to change the distance from the shampoo ball. There has been a demand for a hairdressing chair that can be used for either pre-washing or bathing.

The present invention provides a hairdressing and beauty chair that can run and turn in the front and rear directions, in which the chair can be firmly stopped at any position in the front and rear directions, and can also stop turning. Another purpose of the chair is to control the angle of rotation so that cables, etc. connected between the base that does not rotate and the upper part of the chair that rotates do not get wrapped around the outer periphery of the ram even when the chair rotates. be.

The present invention will be explained below based on 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 1C are tiltable, and the seat 1B is movable up and down.
Moreover, the main body 1, which includes the backrest, seat, apron, etc., is rotatable (swivelable) 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 stand, ie, the shunt 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.
The device shall be moved in the direction toward and away from the object, or may be moved by hand. This base is moved by installing a movable trolley 3 at the bottom of the base 2 having the desired shape. 4a and 4b. Normally, it is desirable to have at least two or more rollers in order to ensure the stability and smooth running of the trolley, and in the case of an electric drive type, any one or two of these rollers should have a built-in electric motor. is used as a driving roller, and the roller 4a is driven by the electric motor.
Or make it so that 4b rotates. In the illustrated embodiment, all the rollers mentioned above are short rolls, but it is also possible to use a combination of long rolls and short rolls.

At the top of the base 2 is a thrust bearing B1.
The seat part 1B of the chair is connected to the support shaft 5 vertically installed at the bottom of the chair.
The seat of the chair, etc. can be freely rotated, and a ram 6 is supported through the support shaft 5 and the base 2. Further, a pipe-shaped shaft 7 is integrally provided on the outer periphery of the ram 6 and at the bottom of the support shaft 5, passing through the cart 3 and projecting slightly from the bottom of the cart, so as to rotate together with the chair seat 1B. At the same time, a swing ring 8 is provided at the lower end of the shaft 7 so as to be freely rotatable with respect to the shaft 7. A swing link 9 is provided on one outer circumferential surface of the swing ring 8 and in a radial direction at the lower surface of the truck.
The link 1 is provided with a protruding structure, and the tip of the swing link 9 is pivotably pivoted to a part of the base 10 by a shaft 11a.
A swing link 9 is pivotally connected to the tip of the swing ring 8 with a pin shaft 12 and protrudes from the swing ring 8 when the truck is moved.
The link 11 is bent and extended, and serves as a stopper to restrict the maximum amount of movement of the truck. A plate-shaped stopper 13 is fixed to the lower end surface of the shaft 7 at one outer periphery of the swivel ring 8 so as to protrude slightly from the end surface of the ring, so that the lower end surface of the swivel ring is rotatably supported. A pin support ring 14 is rotatably supported on the outer peripheral surface of the ring 8, and the pin support ring 1
4, two stopper pins 15a and 15b for forcibly restricting the maximum allowable turning angle of the chair to 360 to 370 degrees and preventing further turning.
are fixed so that they are substantially parallel to the ram and at a predetermined interval. These two stopper pins 15a, 15b are so long that one of them 15a is in contact with the side surface of the stopper 13 at a constant angle when the chair turns, and the other one 15b is designed so that it does not contact the stopper 13 at any position. Keep it short.

Further, a stop device is provided on a part of the outer circumferential surface of the swing ring 8, facing the ring 8.
6a, a pedal 16b fixed to the outer end of the screw rod for rotating the screw rod in forward and reverse directions;
It consists of a pusher 16c that protrudes from the tip of the screw rod and is configured to forcefully press and fix the outer peripheral surface of the swivel ring 8, and when the chair is swiveled with this stop device, the chair can be rotated within the maximum allowable swivel range. It is designed to stop and release the stop at any angle, and when this rotation stops,
The movement of trolleys will also be stopped.

A pedestal 10 having a size at least within this movement range is laid on the floor so that the trolley 2 can smoothly move from the front wash position to the back wash position.
A shaft 11a serving as a pivot point is fixed, and fixed guide rails 18, 18 are provided facing each other on both sides of the upper surface, and this fixed guide rail 18 is engaged with the lower surface of the bogie, so that the bogie 3 can be moved at a predetermined precision. A guide rail 19 is provided so that the vehicle can move forward and backward at a certain position. Note that guide rolls 17 may be provided on both guide rails 18 and 19 so that they slide smoothly against each other.

When the hairdressing chair configured as described above is moved forward or backward, that is, when it is moved from the backward position to the forward position shown by the chain line as shown in FIGS. 1 and 2,
First, release the pressing contact force of the swivel ring by the pusher,
When the chair is moved forward, the swivel link 9 of the swivel ring 8 swivels from the right position to the left position as shown in FIG. In this case, the tip of the swing link 9 is the link 11.
Link 11
Since the length of does not change, the swivel ring swivels,
This is because the link mechanism consisting of the swivel link bends and stretches to change the length of the swivel link 11 and the swivel link 9 in accordance with the distance the chair moves. This turning of the turning ring 8 is performed separately from the turning of the chair. That is, when the chair moves back and forth, the swivel ring 8 rotates accordingly, but the chair does not rotate. Then, the chair is stopped at a limit position within a range of a predetermined maximum movement distance l or at an arbitrary position within this range. This is determined by the distance between the shampoo bowl and the shampoo bowl in the front washbasin.Next, the seat of the chair is rotated according to the hair washing method and adjusted in the desired direction, and then the pedal 16 is adjusted.
When the push tool is brought into strong pressure contact with the outer circumferential surface of the swivel ring through the threaded lever in step b, the swivel ring is fixed, so the bending and extension of the link mechanism is fixed at that position, and the cart is stopped at the stop position. It also becomes impossible to turn, and the installation position of the chair and the direction of the seat are determined.

In this way, the above-mentioned device simultaneously stops the chair from moving and turning at any desired position. Even when the chair seat is released by this stop release device and can freely rotate, the maximum rotation angle of the seat is regulated to prevent cables from getting wrapped around the spindle or shaft (outer circumference of the ram). There are two stopper pins 15a and 15 of different lengths.
b. This is done using the stopper 13 and the pusher 16c. The pin support ring 14 freely rotates on the outer peripheral surface of the swivel ring, but since the swivel ring is fixed with a pusher, when the chair is rotated, the stopper pin 15a is pushed through the stopper 13, and the pin support ring 1 is rotated.
4 rotates to a certain angle, one stopper pin 15b does not come into contact with the stopper 13, but comes into contact with the pusher 16c. That is, until this short stopper pin 15b comes into contact with the push tool 16c, it rotates freely, but when it comes into contact with the push tool 16c, the rotation of the pin support ring 14 is stopped. When the chair is further turned, the pin support ring 14 is stopped, so the long stopper pin 15a also remains stopped in the same manner as 15b and at a constant distance from 15b.
When the stopper 13 comes into contact with this long stopper pin 15a, the rotation of the shaft to which the stopper is fixed is stopped, and the rotation of the chair is forcibly stopped.

In this way, the chair is prevented from rotating more than necessary, and cables and the like are prevented from being wrapped around the chair.

According to the present invention, the pivot link provided on the outer periphery of the lower part of the pivot ring, which is provided so as to be freely pivotable about the shaft protruding from the lower part of the chair, and the link pivoted on the pedestal are pivoted in a bending and extending manner. The moving distance of the chair trolley is regulated by the pusher, and a pusher is provided that faces the outer circumferential surface of the swivel ring and presses against the ring by operating the pedal, so the movement of the trolley can be stopped with a simple operation. At the same time, it also has the advantage of stopping the turning and also reliably canceling the stop.
