Further, an inner partition plate 2 is arranged inside the left and right side plates 1a of the body frame 1, and a shamp ball B is arranged between inner wall surfaces of the inner partition plate 2, and the shamp ball B is connected to the motor M. It can be opened and closed by tilting by driving. This is provided with a pivotal portion for tilting the shampoo ball B at the back end side when the shampoo ball B is used for washing hair or the like, and at the lower end side when the shampoo ball B is stored in the main body frame. Do it. As shown in detail in FIG. 1 and FIG. 2, only the main part of the shamp ball pivoting part is composed of two shafts S1 and S2 projecting from both outer sides of the rear end of the shamp ball B. Composed. The shaft S1 and the shaft S2 may be directly provided on both side surfaces of the shamp ball B, but the shaft S1 is fixed by the reinforcing frame 3 provided in the shamp ball B in order to reinforce the pivot portion of the shamp ball. Further, the shaft S2 is fixed to the tip of the bracket 3B projecting from the shamp ball B. The axes S1 and S2 are arranged in parallel.

A tip end of a locking link L3 is pivotally attached to the shaft S2, and a proximal end side of the locking link L3 is swingably supported by a shaft S3 protruding from the inner partition plate 2.

On the other hand, the shaft S1 is pivotally attached to the tip of the locking link L2, and the other end of the locking link L2 is opposed to the inner partition plate 2,
It is fixed to the shaft 4 which is horizontally mounted between the two. This is the locking link L
The end portion of 2 may be directly fixed to the shaft 4, but in the illustrated embodiment, the fixing metal fitting 5 fixed to the shaft 4 is fixed to the locking link L2 by screws, whereby the locking link L2 is fixed. 4 so that they rotate together with each other, that is, the locking link L
The reference numeral 2 rotates with the shaft 4 about the shaft 4.

The shaft 4 is located away from the top surface of the shamp ball B when the shamp ball B is closed, penetrates between the inner partition plates 2 and 2, and is horizontally extended in the width direction of the shamp ball B.
It is rotatably supported by the inner partition plates 2 and 2 via a bearing 6.

Further, one end of the shaft 4 is projected outward from the inner partition plate 2, and a torque adjuster 9 is arranged at the shaft end.

As shown in FIGS. 2 and 3, the torque adjuster 9 is provided with ball fitting grooves 7A and 7B for fitting and locking the balls 92 on the outer periphery of the boss 7 fixed to the end of the shaft 4. In addition, the short tubular outer cylinder 91, which is fixed to the swing plate 8 on the outer periphery of the boss 7 and fits and supports the ball 92, is rotatably fitted while the ball 92 is fitted to the boss 7. An arcuate leaf spring 93 that presses with a predetermined pressure is arranged on the outer peripheral surface. One or two balls 92 are provided in the outer cylinder 91 by forming a hole in the outer cylinder 91. The leaf spring 93 has an arc shape that covers the outer peripheral surface of the outer cylinder, and one end of the ball 92 is the outer cylinder. It is fixed to 91, the other end is a free end, and the elasticity of this leaf spring 93 is used to
2 is pressed against the boss side with a predetermined pressure.

A locking shaft 11 is provided at the tip of the rocking plate 8 so that the tip of the rocking link L1 is pivotally attached to the locking shaft 11.
The base end of 1 is pivotally attached to one side surface of the rotating disk 12 by a shaft S4. The rotary disk 12 is selectively reversibly driven by a motor M via a power transmission means 13 such as a chain or a belt, and the pivotal position of the swing link L1 by the shaft S4 is shown in FIG. The motor M is driven so as to reciprocate between the lower position shown by the solid line and the upper position shown by the chain line, and the swing link L1 is moved up and down. The rotating disk 12 may be a pulley, a sprocket wheel, or the like.

Then, when a load equal to or greater than a predetermined torque set in advance is applied to the shaft 4, the ball 92 fitted in the one ball fitting groove 7A rides on the outer peripheral surface of the boss 7 against the leaf spring 93, The boss 7 and the outer cylinder 91 are allowed to freely rotate, that is, the boss 7 and the outer cylinder 91 are slid to rotate freely. As a result, when the motor M electrically opens and closes the shamp ball B, even if finger jamming or the like occurs, the shamp ball does not open and close at a torque equal to or higher than the set torque, and safety can be maintained.

Further, in the usual case where the shampoo ball B is opened and closed electrically, the ball 92 is fitted into one of the ball fitting grooves 7A and operated, but as a stopper when the shampoo ball B is manually opened and closed. The ball fitting groove 7 is formed on the outer peripheral surface of the boss 7.
Engrave B. With this manual operation, shampoo ball B
The ball 92 rolls on the outer peripheral surface of the boss 7 by opening and closing the boss 7 inside the fixed outer cylinder 91, that is, the shaft 4
Rotates. As a result, even if it is impossible to open and close the shampoo ball B electrically due to a power failure or the like,
It is possible to manually open and close the shamp ball.

Therefore, the pressing force of the leaf spring 93 of the ball 92 is set to such a torque that the shampoo ball B is lightly opened and closed,
When the torque is equal to or more than this torque, slippage occurs in the torque adjuster 9 so that the shampoo ball B does not open and close even when the motor M is driven.

Further, one end of the tension spring 15 is locked to the spring stopper 14 provided on the upper part of the inner partition plate 2, and the other end of the tension spring 15 is locked to one end of the locking plate 16.

The locking plate 16 is provided with a hook portion 16a at a lower portion thereof, and the locking shaft 11 is locked to the hook portion 16a so that the urging force of the spring 15 always acts on the swing link L1.

The upper and lower positions of the swing link L1 are detected by a limit switch and a striker (not shown) arranged on the swing link L1, and the forward / reverse switching of the motor M and the drive stop control are thereby performed. .

The locking link L2 is arranged on a straight line extending from the straight line connecting the spring 15 and the locking plate 16 when the shamp ball B is closed.

Therefore, in the embodiment configured as described above, when the shampoo ball B in FIG. 1 is operated from the closed state indicated by the solid line to the open state indicated by the chain line, the open operation button (not shown) is operated. The motor M is normally rotated by pushing it. As a result, the pulley 12 rotates in the normal direction, and the shaft S4 moves from the lower position to the upper position. At this time, the swing link L is attached to the shaft S4.
Since 1 is pivotally attached, the rocking link L1 is pushed up. As a result, the shaft 4 is rotated via the locking shaft 11 and the swing plate 8. Since the locking link L2 is fixed to the shaft 4, the locking link L2 swings around the shaft 4.
As a result, the shaft S1 on the front end side of the locking link L2 moves from the solid line position to the chain line position, and the locking link L3 supported by the shaft S3 swings about this shaft S3, and similarly, this link front end. The axis S2 of moves from the solid line position to the chain line position. As a result, the shampoo ball B is brought into a predetermined open state of the chain line position from the closed state of the solid line position in FIG. 1, and the protrusion of the shampoo ball B is also stopped when the motor M is stopped.

Therefore, the shampoo ball B has locking links L2, L3.
Is supported by the shafts 4, S3 via the shaft 4, and when opened, the shampoo ball B largely projects in the forward direction and stops at a fixed position.

In order to move the shampoo ball B from the open state to the closed state, a closing operation button (not shown) is pressed to reverse the motor M and operate the swing link L1 to pull it down. As a result, when the shampoo ball B is opened, the spring 15 is in a contracted state by utilizing its contracting force, but the shaft 4 is reversely rotated via the rocking plate 8 as the rocking link L1 is lowered. The locking link L2 is returned from the chain line position to the standby position shown by the solid line, and the spring 15 is stretched. In this way, the shampoo ball B is automatically opened / closed by the forward / reverse selection drive of the motor M.

Note that when the shampoo ball B is closed, the locking link L2 is located on the extension line of the spring 15, and the locking link L2 is at the dead point position of the spring 15, so that the closed state is maintained. However, if the swinging link L1 rises even a little, the locking link L2 is displaced from its dead center position, so that the chambord can be surely opened.

In addition, when operating the shampoo ball B, especially when it is closed,
For example, when a load equal to or more than a predetermined torque is applied to the shamp ball B due to the fingers being sandwiched by the shamp ball B or the like, even if the swing link L1 moves in the direction of closing the shamp ball B by the rotation of the motor M, The boss 7 and the outer cylinder 91 are slid by the torque adjuster 9 to rotate freely, and the swing link L1
Is transmitted only to the oscillating plate 8, the boss 7 and the shaft 4
Will stop. This is intended to improve safety.

Further, even if the motor M cannot be driven due to the action of the torque adjuster 9 due to a power failure or the like, the opening / closing operation can be manually performed by strongly pushing or pulling the shamp ball in the opening / closing direction at a predetermined torque or more. .

[Effect of device]

According to the present invention, the motor can automatically open and close the shamp ball with a simple mechanism. Moreover, when the shamp ball is loaded with a torque equal to or more than a predetermined torque during the opening and closing operation of the shamp ball, the shamp ball can be operated regardless of the driving of the motor. Since the opening / closing operation is stopped, safety can be improved.

Further, according to the second aspect of the present invention, even when the motor cannot be driven due to a power failure or the like, it is possible to manually and accurately open and close the shamp ball and hold it at a predetermined position.
