Description

[Detailed description of the invention]

[0001]

The present invention has two treatment elements which perform different operations, for example, a massage operation such as tapping and vibration, in opposite directions, and each treatment element is driven by a single motor. The present invention relates to a portable massage machine.

[0002]

2. Description of the Related Art Conventionally, this type of massage machine has been disclosed
No. 40516 (A61H7 / 00) and Jitsuhei 3-9
No. 94 (A61H23 / 02), however, these treatment elements are not used because the operation of the two treatment elements is not independent and the two treatment elements operate simultaneously when the motor is driven. Becomes an unnecessary operation, and there is a problem that power is wasted and noise is increased.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a portable massage machine with low power consumption and low noise.

[0004]

SUMMARY OF THE INVENTION The present invention is directed to a portable massage machine having two treatment elements operating in different directions and operating each treatment element with a single motor. The power is transmitted to the child through a first one-way clutch that operates by the forward rotation of the motor, and the second treatment element is powered by a second one-way clutch that operates by the reverse rotation of the motor. Is transmitted.

[0005]

When the motor rotates in the forward direction, the first one-way clutch operates to transmit power to the first treatment element. At this time, the second one-way clutch does not operate, and no power is transmitted to the second treatment element. When the motor rotates in the opposite direction,
This time, the second one-way clutch operates to transmit power to the second treatment element. At this time, the first one-way clutch does not operate, and no power is transmitted to the first treatment element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG.
1 is an overall perspective view of a portable massage machine, 1 is a T-shaped main body case composed of a handle 2 and a body 3, and a switch 4 for switching between hit massage and vibration massage is provided on the handle 2. And a power supply unit such as a battery (not shown). At both ends of the body 3, a hitting head 5 serving as a first treatment element and a vibrating head 6 serving as a second treatment element are provided.

FIG. 2 shows details of the inside of the body 3, and reference numeral 7 denotes a motor supplied with power from the power supply unit. A pair of output shafts of the motor 7 project in opposite directions.
A worm 10 is fixed via a first one-way clutch 9, and a worm wheel 11 is meshed with the worm 10. One end of a link 13 is connected to the worm wheel 11 at a position eccentric from the shaft 12, and the other end of the link 13 is connected to a piston 14. The shaft 14 of the hitting head 5 is connected to the piston 14. The piston 14 reciprocates right and left in the gear case 16 via the link 13 by the rotation of the worm wheel 11, and reciprocates the hitting head 5. The first one-way clutch 9 couples with the worm 10 to rotate the worm when the output shaft 8 rotates in the forward direction, and transmits the rotational force to the worm 10 when the output shaft 8 rotates in the reverse direction. Not to be.

A clutch holder 19 is fixed to the other output shaft 17 of the motor 7 via a second one-way clutch 18. The second one-way clutch 18 transmits rotation to the clutch holder 19 when the output shaft 17 rotates in the reverse direction, and does not transmit rotation when the output shaft 17 rotates in the forward direction, contrary to the first one-way clutch 9. It has become.

Reference numeral 20 denotes a split shaft having an eccentric split cylinder 21, which is connected to a clutch holder 19 via a joint spring 22. The split shaft 20 is supported by a back case 23 constituting the vibration head 6. The vibrating head 6 includes a back case 23, a front case 25, a spring receiving tube 26, and a pad 27. The back case 23 is sandwiched between the spring receiving tube 26 and the front case 25. The pad 27 is made of an elastic material and is mounted so as to cover the front case 25.

The vibrating head 6 is swingably attached to a spring receiver 28 provided on the body case body 3 by a coil spring 29. The coil spring 29 has one end wound around the spring receiver 28 and the other end wound around the spring receiving cylinder 26. 30 is the coil spring
It is a bellows body to hide 29.

Next, the operation will be described. When the changeover switch 4 is set to “hit”, the output shaft 8 of the motor 7 rotates forward. In this case, the first one-way clutch 9 is operated to cause the warp.
Then, the second one-way clutch 18 does not operate, and no torque is transmitted to the clutch holder 19.

Accordingly, the hitting head 5 is reciprocated right and left through the worm wheel 11, the link 13, and the piston 14,
By hitting the hitting head 5 to the affected part, hitting massage can be performed. At this time, clutch holder 19
Does not rotate, the vibrating head 6 does not vibrate.

When the changeover switch 4 is set to "vibration",
The motor output shaft 17 rotates in the reverse direction. In this case, the second one-way clutch 18 operates to rotate the clutch holder 19, but the first one-way clutch 9 does not operate and does not transmit the rotational force to the worm 10.

Therefore, the rotation of the clutch holder 19 is transmitted to the dividing cylinder shaft 20 via the joint spring 22, and the eccentric weight 21 rotates to vibrate the vibrating head 6. Vibration massage can be performed by applying the vibration head 6 to the affected part. At this time, the hitting head 5 does not move because the worm 10 does not rotate.

By changing the direction of rotation of the motor 7 by the changeover switch 4, only one of the two treatment elements 5 and 6 is operated. Is not consumed. In addition, since the treatment element that is not used does not move, the noise is reduced accordingly.

[0016]

[Effects of the Invention] According to the present invention, power consumption can be reduced,
It is also possible to provide a portable massage machine with low noise and easy to use.
