Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a moving device for a hairdressing chair.

Conventional techniques and their problems In barbershops, the hair is usually washed and conditioned after the hair is cut.As a method of washing hair, the hair to be conditioned is placed in a shampoo bowl attached to the dressing table as shown in Figure 4A. There are two methods: a pre-washing method in which the person leans forward, and a back-washing 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 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 both pre-washing and bathing.

Further, even when performing pre-washing, it is convenient to move the chair each time so that the customer can always wash their hair while sitting on the chair, depending on the shape and size of the customer.

In such a case, the present invention is designed to electrically move the chair in the direction toward and away from the shove ball.

A solution to the problem: A movable trolley equipped with rollers is placed on a pedestal, and a threaded rod that is driven forward and backward by a motor is installed on this moving trolley, and both ends of the threaded rod are rotated in different directions. Screws are carved and threaded bodies are screwed into these, and these threaded bodies and a support shaft provided on the base are connected via a bendable and extensible link mechanism, and a hairdressing chair is created by driving the motor forward and backward. To improve work efficiency by moving a movable trolley on which a chair is placed back and forth, thereby making it possible to easily and quickly adjust the set position of a chair.

Embodiment In the figure, 1 is the main body of a hairdressing chair, the detailed mechanism of which is omitted from illustration, but as is commonly used, the backrest 1A and apron 1C can be tilted freely, and the seat 1B can be raised and lowered. Moreover, the main body 1 consisting of the backrest, seat, apron, etc. is rotatable (swiveled) relative to the base 2, and the backrest, seat, etc. can be tilted or rotated at any position. This configuration is the same as the conventional one. Also, the main body 1
A base 2 that supports the main body 1 is automatically moved to a mirror stand, that is, a dump ball B by switching the electric motor for movement using a foot switch or a manual switch provided on the main body or a moving cart (to be described later) on the floor. so that it moves toward and away from the object.

The chair body is moved by placing a base 2 of a desired shape on a movable trolley 3, and this flat movable trolley 3 has a plurality of movable parts that support the load of the chair body and the person receiving haircut. rollers (or wheels) 4
a, 4b. Normally, at least two rollers are placed on the bottom of the front and rear ends to ensure stability and smooth running of the cart, but the number of rollers installed can be changed as long as the cart is stable and can move smoothly. It is possible.

This movable trolley 3 may be driven directly on the floor of the hairdressing salon using rollers, but in order to enable smooth running, a flat base 5 at least as large as the moving range of the movable trolley is used. is placed on the floor.
A spindle mount 6 is fixed onto the pedestal 5 and at the end on the side of the shampoo ball, and a spindle 7 is provided protruding from the mount 6, and two short links 8, 8 are attached to the spindle 7. Provides pivot support. As mentioned above, the moving rollers 4a and 4b are provided on the lower surface of the movable trolley 3, and guide rails 9, 9 parallel to the traveling direction of the trolley are vertically installed on the lower surface of the movable trolley vehicle side via rail fixtures 10. , a guide roller 12 rotatably supported by a guide roller mounting frame 11 provided on a pedestal is brought into contact with the outer surface of the guide rail, and the traveling direction of the movable cart is regulated by the guide roller and rail, The vehicle is made to travel back and forth at precisely determined positions.

Further, a threaded rod 13 is arranged on the lower surface of the movable trolley 3 in a direction intersecting with the traveling direction, and both ends of the threaded rod are rotatably supported by bearings 14 protruding from the lower surface of the trolley. Both ends are threaded in different directions, that is, one has a right-hand thread and the other has a left-hand thread, and the threaded rod 13 and the motor 15 provided on the truck are connected through a power transmission mechanism 16 in forward and reverse directions. can be selectively rotated. This power transmission mechanism 16
are pulleys 16a and 16 provided on the threaded rod and motor.
In the illustrated embodiment, a belt 16c is stretched between the belts 16c and 16c, but the pulley belts may be replaced with gears or sprocket wheels and chains. The right-hand threaded portion and the left-hand threaded portion of the threaded rod 13 are provided with threaded bodies 17a and 17a, respectively, facing each other.
7b are screwed together, and a pivot 1 is attached to each screwed body.
Two long links 19 intersecting at 8.
19, and this long link 19,
The other end of 19 is pivotally connected to one end of the short link 8 via a pin 20, and by rotating the threaded rod in the forward or reverse direction, the threaded bodies 17a and 17b move away from each other or toward each other along the threaded rod. When moving,
The long link and short link are bent and extended, and the support shaft 7 and screw rod 1
By changing the distance between the movable trolley 3 and the movable trolley 3 via a link mechanism whose one end is supported by
The vehicle is placed on a pedestal and is regulated by guide rails.

The movable trolley 3 is provided with a foot switch mounting seat 21 for selectively moving the trolley forward or backward, a pedal mounting seat 22 for raising and lowering the chair, tilting the chair, and the like.

In addition, in the figure, 23 indicates a tension pulley that adjusts the slack of the belt or chain in the case of a system in which power is transmitted by a belt or chain. It is supported through L.

Operation In the barber chair moving device configured as described above, when the motor 15 is rotated in the forward rotation direction by operating a switch, the two threaded bodies approach each other due to the rotation of the threaded rod, thereby The link mechanism extends and the moving carriage moves away from the support shaft 7, i.e. moves backward, and conversely, when the motor is rotated in the reverse direction, the link mechanism bends and the moving carriage moves forward. By bending and stretching this link mechanism, the traveling cart is guided by the guide rail on the pedestal and moves forward and backward, and the moving cart stops at the position where the motor is stopped. It is made to stop automatically in the reverse position.

Effects of the Invention According to the present invention, the pedestal and the cart are connected via a screw rod and a flexible link from a motor mounted on a movable cart that runs on a pedestal, so that the motor can be switched between forward and reverse directions. This has the advantage that the hairdressing chair can be moved automatically and stably.
