The description is omitted.

The kneading balls 17 are restricted in their movements by the first negative pressure drive section 23, the second negative pressure drive section 24, and the direction changing section 22, and the first and second negative pressure drive sections 23, 24 are controlled. Vacuum drive source 25
Is composed of four electromagnetic valves 41 to 44, a vacuum tank 45, a vacuum pump 46, and a conduit such as a hose connecting these instrument parts. Of the four solenoid valves 41-44, the two solenoid valves 41, 42 drive the second negative pressure drive unit 24, and the remaining two solenoid valves 43, 44 are the first solenoid valves 43, 44. It functions as a drive unit for the negative pressure drive unit 23. The vacuum drive sources of the first and second negative pressure drive units 23 and 24 in the kneading balls 18 are also configured by using four solenoid valves 41 'to 44' in the same manner.

In this embodiment, the massage operation of the massaging balls 17, 18 is performed as follows. First, the vacuum pump 46 is operated to evacuate the inside of the vacuum tank 45, the rear chamber 47 inside the housing 33 of each negative pressure drive unit 23, 24, and the inside of the pipeline, and then the solenoid valves 41 to 44, 41 '~. Close 44 '. In this state,
For example, when the solenoid valves 41, 41 'are opened intermittently little by little, the rear chamber 47 of the housing 33 in the second negative pressure drive unit 24 is opened.
5, the diaphragm 34 is gradually weakened, and the diaphragm 34 moves in the forward direction (the tip direction of the kneading balls) in FIG. 5, and the pressing force of the kneading balls 17, 18 to the back becomes stronger. On the other hand, the solenoid valves 41, 4
When 1 ′ is closed and the solenoid valves 42, 42 ′ are opened intermittently, the negative pressure in the vacuum tank 45 acts on the solenoid valves 41, 41 ′ via the solenoid valves 42, 42 ′, and the second negative pressure is applied. The negative pressure in the rear chamber 47 of the housing 33 in the drive unit 24 increases and the diaphragm
34 moves rearward against the pressing force of the spring 40, and the pressing force on the backs of the massaging balls 17, 18 becomes weak. In this way, the kneading balls 17, 18 are moved back and forth by the valve operation of the solenoid valves 41, 41 'and 42, 42', so that the pressing force on the back by the kneading balls 17, 18 is increased or decreased. Similarly, the operation of the first negative pressure drive unit 23 is performed by the opening / closing operation of the solenoid valves 42, 43 'and 44, 44'.
When the negative pressure of the rear chamber 47 of the housing 33 of the negative pressure drive unit 23 is weakened, the link 32 moves forward, the massaging balls 17 are moved from right to left, and the massaging balls 18 are moved horizontally from left to right toward the spine. Move to. When the negative pressure of the rear chamber 47 in the housing 33 of the negative pressure drive unit 23 is increased, the link 32 is moved to the diaphragm 34
The massaging balls 17 are moved backward by the negative suction force, and the massaging balls 17 horizontally return from left to right and the massaging balls 18 horizontally from right to left in the direction away from the spine. By the forward and backward movement of the shaft 31 and the horizontal movement of the link 32, the driven bearing 30 becomes a cam groove.
It rolls along the cam surface of 28, and the effective massage operation is performed by combining the strength of the pressing force of the massaging balls 17, 18 and the horizontal movement.

FIG. 6 shows the mechanism for moving the massaging balls 17, 18 up and down, that is, the mechanism for moving the main body 15 of the massage machine 4 up and down. This moving mechanism is also performed by the third negative pressure driving unit 48 and the fourth negative pressure driving unit 50, similarly to the horizontal and front and rear moving mechanisms of the kneading balls 17, 18. These negative pressure drive
The structures of 48 and 50 are the same as those of the first and second negative pressure driving units 23 and 24, and the tip of the vertical movement shaft 51 of the third negative pressure driving unit 48 and the fourth negative pressure driving unit 48 are arranged. The tip of the link 52 of the drive unit 50 is rotatably connected to the drive gear 53.

The drive gear 53 meshes with an intermediate gear 54, and this intermediate gear 54 meshes with a gear 69 of the main shaft 10. Due to the combination of the vertical movement of the vertical movement shaft 51 and the horizontal movement of the link 52, the drive gear 53 rotates in a desired direction of a clock or a counterclockwise, and this rotational force is an intermediate gear.
It is transmitted to the gear 69 via 54, and the main shaft 10 rotates. As the main shaft 10 rotates, the gears 8 and 9 engage with the rack teeth 7 of the support plate 5 and roll, so that the main shaft 10 moves up and down, that is, the body 15 of the massage machine 4 moves up and down. Then, the massaging balls 17 and 18 move vertically along the back. In addition, the vertical movement of the diaphragm 34 of the third negative pressure drive unit 48 is performed by the two solenoid valves 55, 56.
The horizontal movement of the link 52 is performed by the two solenoid valves 57 and 58.

Solenoid valves 41-44 for restricting the movement of the kneading balls 17 in the horizontal direction and the strength direction, solenoid valves 41'-44 'for restricting the movement of the kneading balls 18 in the horizontal direction and the strength direction, and the kneading balls 17, 18 The solenoid valves 55 to 58 that regulate the vertical movement of the
Is configured as a vacuum unit 60 sharing (FIG. 6),
The vacuum unit 60 is attached to the bathtub 1 or the bathroom wall surface 61. In the figure, 62 indicates a pressure sensor. The pressure sensor 62 detects the pressure in the rear chamber 47 of the housing 33 in each negative pressure drive unit, and sends the detection result to a controller (not shown). The control device uses the pressure detected by the pressure sensor 62 to detect the shaft 31, 51 and link 32,
While confirming the movement position of 52, the opening / closing control of each solenoid valve 41-44, 41'-44 ', 55-58 and the operation control of the vacuum pump 46 are performed based on the designated massage mode.

As described above, according to the present embodiment, the vacuum unit 60 is driven in vacuum to move the massaging balls 17 and 18 in the massaging direction and the massaging machine 4 moves up and down (the massaging balls 17 and 18 move up and down). It is possible to massage while bathing in the bathtub 1.

In this way, the massage can be done while immersed in warm water, so you can feel the exhilarating feeling of warm water, and the massage will be done in the state where blood circulation is improved by being warmed by the bath water. The massage effect will also increase.

In general, it is said that the effect of massage using warm water is most effective when it is performed in a cold head temperature. From this point of view, it is desirable in terms of massage effect that the bathtub 1 is configured as a shallow bathtub in which only the lower half of the body is soaked, and a massage machine is attached to this bathtub. However, in Japan, because of many years of practice, unless you soak your shoulders or neck in hot water, you don't feel like bathing in the bathtub, and you feel uncomfortable with a bath that only lower body is soaked. In consideration of this point, in the present embodiment, the massage machine 4 is attached to the general bathtub 1 which can be soaked up to the shoulder or the neck, so that both the comfortable feeling of taking a bath and the massage effect can be satisfied. .

Further, in the present embodiment, since the drive source of the massage machine 4 is constituted by the vacuum drive source, there is no concern about electric leakage,
Very safe to use. Further, since the massage machine 4 is attached to the outside of the bathtub 1, the inside of the bathtub 1 does not become narrow, and the user can enjoy the massage in a relaxed mood.

The present invention is not limited to the above embodiment,
Various embodiments may be adopted. For example, in the above embodiment, in order to simplify the explanation, the movement of the massaging balls 17 and 18 was described as a simple massaging operation that involves only the movement of the pressing force and the horizontal movement with respect to the back. Alternatively, by combining known mechanisms, more complicated massage operations, such as, for example, kneading up, kneading down, hitting, stretching the back muscles, stretching the neck muscles, and hitting a local portion, can be performed.

Further, in the above embodiment, the driving source for the massage operation of the massaging balls 17, 18 is constituted by the vacuum driving source, but it may be constituted by using the electric driving source. In this case, for example, as shown in FIG. 7, for the strong and weak pressing movements of the massaging balls 17, 18, a worm gear 63 is provided on the base end side of the shaft 31, and the worm gear 63 and the gear 65 on the output shaft side of the motor 64 are provided.
The shaft 31 by engaging the
Can be moved back and forth to change the strength of the pressing force of the kneading balls 17, 18, and similarly, a worm gear 66 is provided on the proximal end side of the link 32, and this worm gear 66 is connected to the gear 68 of the motor 67. It is possible to move the links 32 forward and backward using the forward and reverse rotations of the motors so as to move the kneading balls 17 and 18 horizontally forward and backward. If the gear 8 is rotated by a motor, the main body 15 can be moved up and down.

Further, in the above embodiment, the kneading body is constituted by the kneading balls 17, 18, but it can be constituted by rollers.

Further, the kneading body may be constituted by a vibrating plate, and the back, shoulders, neck, etc. of the bather may be vibrated to perform the massage.
