Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a movement control device for a barber chair.

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 1A. 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 equipped accordingly.

Therefore, in barbershops that use 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. 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 for 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 proposes a control device that moves the chair forward and backward according to the customer's request and changes the distance to the shampoo ball so that both pre-washing and back-washing methods can be easily adopted. The following description will be given based on the illustrated embodiment.

In the figure, 1 is the main body of the barber chair, and although not shown, the backrest 1A and apron 1C are tiltable, the seat 1B is movable up and down, and the main body consists of the backrest, seat, apron, etc. 1 is the base 2
It is rotatable relative to the Similar to the conventional method, this system allows tilting and rotation to be stopped or canceled at any position. Furthermore, the base 2 supporting the main body 1 operates a foot switch on the floor, a switch provided on the main body 1, and a switch (switch of the electric motor for transportation) that is operated by rotating the seat. As a result, it is automatically moved toward and away from the mirror stand, that is, the shove ball. This is done by providing a movable trolley 3 at the bottom of a base 2 having a predetermined shape, and this movable trolley 3 is equipped with a plurality of rollers (or wheels) 4 that can bear the load of the chair body and the hair recipient. It is usually desirable to have at least two or more rollers in order to ensure stability and smooth running of the truck. Further, the roller 4 may be a long type or a short wheel type.

As mentioned above, the movable trolley 3 on which the base 2 is installed can be moved directly on the floor using the rollers 4, but as shown in the drawing, it is possible to move the movable trolley 3 over the moving range l for smoother movement. It is used by laying a flat substrate on the floor. The board 5 is of course installed on the floor at the location where the chair is installed and within the range of movement, but it may also be fixed to the floor.

Guide rails 6 and guide wheels 7 are provided so that even if the movable trolley 3 is repeatedly moved, the distance between the shove ball B and the fixed position is restricted to a predetermined distance and on an accurate trajectory, and the movable trolley 3 moves accurately. If the roller 4 is a long type, the roller 4 should be placed outside the roller 4 so that it does not interfere with the rolling of the roller, and if the roller 4 is a short type, the roller 4 should be placed between the left and right opposing rollers 4, and the roller 4 should be placed between the rollers 4 facing each other on the left and right. One or two guide rails 6 are arranged on the floor or a board along the moving direction, and a guide wheel 7 is vertically provided on the lower surface of the moving trolley, and the guide wheel 7 is brought into contact with the guide rail. This system restricts the movement of mobile carts.

In addition, a guide groove is provided along the guide rail to prevent the mobile cart from falling over due to unbalanced loads such as chairs, and a part of the guide wheel, such as a flange, is fitted to this guide groove, or a part of the guide ring is placed protruding from the side of another mobile cart. The sliding protrusions are engaged.

Although the means for moving the movable trolley is not specifically shown, a drive roller having a built-in motor inside the roller provided at the bottom of the movable trolley may be used, or a driving device may be installed on the movable trolley to move the roller or on the wheels,
The power may be transmitted through a power transmission mechanism such as a chain, belt, or gear, or furthermore, a drive device may be installed outside the movable cart at a location that does not interfere with hair styling work, such as under the dressing table. This is done by connecting a drive device and a moving truck. If this drive device is a hydraulic cylinder, the rod end is attached to a part of the moving truck, and if it is an electric cylinder, a part of the threaded rod is connected to the moving truck. The trolley is moved by the rod of the hydraulic cylinder that is screwed into the side, or by the forward and reverse rotation of the screw rod of the electric cylinder. In addition, linear motor link mechanisms can also be adopted, and cylinder rods and screw rods have grooves or other grooves on the floor to prevent workers from tripping, and are placed in these grooves to prevent dirt from entering the opening of the groove. Sometimes a cover is attached.

Furthermore, in this moving system, a chain that rotates forward and backward is buried under the floor surface, and a narrow groove, such as a slit-shaped groove, is provided in the floor surface along the direction of movement of the moving trolley, and it is fixed to the chain through this groove. It is also possible to provide a metal fitting protruding above the floor surface, engage this metal fitting to a part of the movable cart, and move the metal fitting by forward and reverse selection drive of the chain. In addition, when a movable trolley equipped with this chair is moved, when the seat on the base fixed on the movable trolley is turned to the right or left by a certain angle, the drive device is turned on in the forward or backward direction of the trolley. switch so that
A striker 8 is provided protruding from the base side to which SW1 and SW2 are fixed, and from the lower end of the seat side, for example, the lower end of the cylinder. The positional relationship between this switch and the striker is shown in FIGS. 4 and 5, and a wiring diagram is shown in FIG. 6 as an example. Switch SW1 and SW2
A switch mounting plate 9 is provided protruding from the base 2 through a bracket 10, and limit switches are respectively mounted on the mounting plate at predetermined angle positions with respect to the longitudinal axis of the moving truck as shown in FIG. SW1 and SW2
will be established. This limit switch SW1, SW2
In the illustrated embodiment, they are provided as a pair, facing each other on both sides of the axis, but they may be provided only above or below the axis in FIG. The limit switches are placed along this axis and facing each other.
SW3 and SW4 are arranged on a switch mounting plate, and the chair is selectively moved forward and backward by the limit switches SW3 and SW4. The electric circuit of this switch and the motor for forward and backward movement is shown in FIG.

In the case of the above-mentioned configuration, when moving the chair from the front sink position to the back shampoo position by rotating the chair by a certain angle to the right or left with respect to the shampoo table, the chair facing forward can be moved from the front wash position to the back wash position. When the chair is rotated a certain angle so that it faces backwards, the switch is turned on for backward movement, and the chair moves backward. When it reaches a predetermined position, it is stopped at the fixed position by the action of the limit switch. At this time, if you turn the chair so that it faces backwards, you will be able to perform the back lift. Conversely, the same procedure can be used when advancing from the back seat position to the front wash position.

According to the present invention, by rotating only a predetermined angle of the chair either to the right or left, the motor for forward and backward movement is selectively driven in forward or reverse rotation, automatically moving to a predetermined position. This has the advantage of being able to selectively move back and forth quickly and easily according to the customer's requests.
