An oblique left rear lock hole 80G is provided. Then, from the forward-facing lock hole 80A, counterclockwise (counterclockwise), the right diagonal front lock hole 80B, the right-facing lock hole 80D, and the right diagonal rear lock hole 80F are sequentially formed with a predetermined interval center angle α. Provided.
In other words, a plurality of lock holes 80 are provided at equal intervals around the vertical axis La (with a predetermined interval center angle α), and the forward lock hole 80A (with respect to the vertical axis point La ′ in plan view) is provided. The backward-facing lock holes that are point-symmetrical positions are omitted.

The interval center angle α is preferably set to 25 degrees or more and 50 degrees or less. By setting in this way, it is easy to use and can be locked at a chair rotation position where treatment and seating / leaving are easy depending on the situation.
In the illustrated example, the interval center angle α is 45 degrees. That is, the chair body 1 can be locked every 45 degrees within the range from the forward-facing chair rotation position (see FIG. 3) to the clockwise direction to the right oblique rear chair rotation position (see FIG. 7). In addition, it can be locked (positioned) every 45 degrees within a range from the forward chair rotation position (see FIG. 3) to the counterclockwise left rear chair rotation position (not shown).
Not limited to the illustrated example, a plurality of lock holes 80 may be provided sequentially clockwise or counterclockwise from the forward-facing lock hole 80A with an interval central angle α of 30 degrees. That is, it may be provided so that it can be locked every 30 degrees within the range from the forward chair rotation position to the right diagonal rear chair rotation position or within the range from the forward chair rotation position to the left diagonal rear chair rotation position.

Next, the usage method (action) of the barber / beauty chair of the present invention will be described.
As shown in FIG. 8, a chair chair rotation position in which the chair body 1 faces the front side Na and the chair minimum position in which the hydraulic cylinder 2 is shortened will be described as a reference state before the operation is started.
First, in the above-described reference state in which the chair operator is not operating, the lock rod 33 receives the upward elastic force of the elastic biasing member 34, and the upper end portion 33a has a forward-facing lock hole 80A (for treatment). It is inserted into the lock hole 81).

  In this reference state, the lock rod 33 prevents the connection member 32 from rotating about the vertical axis La. Therefore, even if the chair operator swings the chair body 1 in the left-right direction, the guide rod 31 fixed to the chair body 1 is inserted into the guide hole 32c of the connecting member 32 that is locked. Rotation is impossible.

  When the chair operator depresses the second foot switch 37 (see FIG. 2) in the locked state, the rod 20 protrudes upward and the hydraulic cylinder 2 extends as shown in FIG. The guide bar 31 attached to the chair main body 1 is lifted while being guided by the guide hole 32c, and prevents the chair main body 1 from tilting downward in the front Na, the rear, or the left-right direction.

  Further, when the first foot switch 36 is depressed, the rod 20 is accommodated in the barrel portion 21, the hydraulic cylinder 2 is shortened, and the guide rod 31 is lowered while being guided (guided) by the guide hole 32c of the connecting member 32. The tilt of the main body 1 is prevented.

Further, when the chair body 1 moves up and down, the connecting member 32 prevents the rotation (revolution) movement of the guide bar 31 around the vertical axis La, so that the rotation of the chair body 1 is smoothly and stably. Go up and down.
That is, since the chair body 1 can be lifted and lowered in the locked state, it is not necessary to perform the locking operation after performing the lifting operation.

  When the chair body 1 is rotated, the guide bar 31 is lowered by stepping on the distal end portion of the release pedal 35, and the upper end portion 33 a is pulled out from the lock hole 80. The connecting member 32 can rotate around the vertical axis La, and the chair body 1 is rotated around the vertical axis La by the chair operator manually.

If the chair operator arranges the chair body 1 at a desired chair rotation position and stops the release pedal 35, even if the operation for locking is not performed, the elastic force of the elastic urging member 34 is used. The lock rod 33 automatically rises and is inserted into the lock hole 80, and is locked.
For example, the chair body 1 does not rotate with respect to the chair main body 1 in the right-facing chair rotation position, and the chair main body 1 does not rotate even if the armrest 13 or the foot treading part 14 puts a weight on the chair main body 1 and balance You can get on and off without breaking down.

Further, when the lock bar 33 is raised, if the lock hole 80 is not provided at an upper position of the lock bar 33, the upper end 33a contacts the lower surface 32e of the connecting member 32. Since the lock bar 33 always receives the upward elastic force and tries to enter the lock hole 80, if the chair operator swings the chair body 1 slightly in the left-right direction, the upper end 33a of the lock bar 33 moves the lower surface 32e. When sliding (the upper end portion 33a and the lower surface 32e are in sliding contact) and the lock hole 80 corresponds to the lock rod 33, the upper end portion 33a is inserted by itself (inserted by the elastic urging force) to be locked.
In addition, since the upper end portion 33a is formed in a tapered shape, if the upper end of the lock rod 33 reaches the lock hole 80 even a little, the lock hole 80 is attracted (directed) directly above the lock rod 33.

  In the present invention, the design can be changed, and the connecting member 32 and the slide guide member 39 are preferably attached to the barrel portion 21 as shown in the figure, since the number of parts can be reduced. A fixing member for fixing 39 and the connecting member 32 may be erected on the base member 30. Alternatively, a pair of upper and lower outer flange portions may be provided on the barrel portion 21 so that the connecting member 32 is held at a predetermined height position by the pair of outer flange portions and can be freely rotated around the vertical axis La.

  As described above, the barber / beauty chair of the present invention is a barber / beauty chair provided by connecting the chair body 1 to the rod 20 of the hydraulic cylinder 2 so as to be movable up and down and rotatable around the vertical axis La. A guide rod 31 attached to the main body 1 in a hanging manner, and a guide hole 32c through which the guide rod 31 is slidable up and down are provided to be rotatable around a vertical axis La and held at a predetermined height position. The connecting member 32, the lock rod 33 in which the upper end portion 33a is removably provided in the lock hole 80 provided in the connecting member 32, and the lock rod 33 upward so that the upper end portion 33a is inserted into the lock hole 80. A bullet urging member 34 that constantly urges and urges the lock, and an unlocking foot pedal 35 that slides the lock rod 33 downward against the bullet urging member 34 and removes the upper end 33a from the lock hole 80. When the chair body 1 is raised and lowered, the chair body 1 To prevent rotation of the vertical shaped axis La around, without causing a feeling of uneasiness in the person to be treated can be raised or lowered safely and smoothly. Even if the chair body 1 is not locked, the lock bar 33 is always elastically biased upward, so that the lock is automatically applied and the patient can sit and leave safely and safely. Can do. After the unlocking operation, it is not necessary to perform the locking operation, and it is excellent in operability and can be used safely. Complex electric control and hydraulic control are not required for the lock means (lock structure), the structure can be simplified, and the production can be performed quickly and easily (cheap).

  Further, a plurality of lock holes 80 are formed around the vertical axis La in the connecting member 32, and a treatment lock hole 81 for preventing the chair body 1 from rotating at a chair rotation position for performing treatment, and a person to be treated. Since it has a seating / leaving lock hole 82 for preventing the rotation of the chair body 1 at the chair rotation position for getting on and off, it is easy for the practitioner to perform a haircut, perm, etc. The chair body 1 can be moved up and down while the rotation of the chair body 1 is locked at the chair rotation position. The chair body 1 can be raised and lowered smoothly and stably without the chair body 1 swinging from side to side. The chair body 1 can be locked (positioned) at the chair rotation position where the treatment person can easily get on and off, and the chair height can be adjusted to be easy to get on and off in the locked state at the chair rotation position.

  Further, in rear view, a first foot switch 36 for lowering the chair body 1 and a second foot switch 37 for lifting the chair body 1 are arranged side by side in the left-right direction. Since the unlocking foot pedal 35 is disposed at an intermediate upper position between the switch 36 and the second foot switch 37, the unlocking operation and the raising / lowering operation can be performed without using the hand (while the hand is free). . For example, since it is sufficient to hold the treatment tool, the unlocking operation can be performed easily and quickly. An erroneous operation can be prevented, and the raising / lowering operation and unlocking operation of the chair body 1 can be performed safely and appropriately. The base part 3 can be made compact.
