[Industrial application] The present invention is a hand-held massager.
Regarding

[0002]

2. Description of the Related Art A conventional hand-held massager is disclosed, for example, in Japanese Patent Publication No. 26505/1990. This massager has a vibrating part and a main body part,
The main body is provided with a battery and a drive motor, the vibrating part is provided with an eccentric weight connected to the drive motor via an axial shaft, and the vibrating part is vibrated by the rotational vibration of the eccentric weight. By the way, in this massager, the vibrating part is fixed, and when the vibrating part is pressed against the affected part to be used, the vibrating part may not be sufficiently hit depending on the affected part, resulting in poor usability. .

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described points, and a hand-held type in which the vibrating part sufficiently contacts the affected area regardless of where the affected area is, and an excellent massage effect is obtained. It provides a massager.

[0004]

SUMMARY OF THE INVENTION The present invention comprises a ring-shaped massage head, and a head case and a head case cap that sandwich the massage head from both ends. The massage head is a head case or a head case. The head case or the head case cap has a plurality of recesses for engaging and disengaging the ball bearing, while the ball bearing elastically presses the joint surface with the cap.

[0005]

According to the present invention, the ring-shaped massage head is held by the spring in the head case or the head case cap by a predetermined pressure contact force, and at the same time, is rotatably supported by the ball bearing. Further, as the massage head is rotated, the ball bearing is engaged with and disengaged from a plurality of recesses formed in the head case or the head case cap, so that the massage head rotates in a stepwise manner in several steps.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is a massager according to the present invention,
It is composed of a cylindrical grip portion 2 and a pair of massage portions 3 and 4 attached to both ends thereof. The grip portion 2 includes a battery pack 6 in which two driving Ni-Cd batteries 5 are connected in series. Denoted at 7 is a detachable ring that is screwed and fixed. When the battery pack 6 is replaced or charged, the detachable ring 7 is loosened to separate the grip portion 2 and the massage portion 3.
A switch ring 8 turns on / off the switch by rotating the switch ring. That is, a printed circuit board having the reed switch 9 inside the switch ring 8.
10 is provided, and a permanent magnet 11 is attached to the inner wall of the switch ring facing the reed switch 9.

Each of the massage parts 3 and 4 has a ring-shaped massage head 12, a head case 13, and a head case cap 14 which form an exterior. The head case 13 is connected to the grip portion 2. Inside the massage part, the motor 15 for vibration output, the motor case 16, and the eccentric weight connected to the output shaft of the motor
17 and are provided. The motor 15 is fixed to the motor case 16 and then fixed to the head case cap 14 with screws 18.

The massage head 12 is a head case 13
It is clamped and fixed by and the head case cap 14. The massage head 12 is formed of an elastic member made of an elastomer suitable for massaging and seals the sandwiched portion. The head case 13 and the head case cap 14 are respectively screwed into a pair of screw rings 19. The pair of screw rings 19 are ring-shaped rubber members.
It is fixed at 20. This rubber material 20 is made of elastomer.
It is formed with. As mentioned above, the massage parts 3, 4
Is kept liquid-tight to prevent water from entering inside.

On the other hand, in this massager-1, the rotational vibration of the eccentric weight 17 is transmitted to the massage head 12 via the head case cap 14 to massage the affected area. Here, since the head case cap 14 and the head case 13 are fixed to each other via the rubber material 20, the vibration of the head case cap 14 is absorbed by the rubber material 20, and the vibration is transmitted to the head case 13. It is suppressed to be done. As a result, transmission of vibration to the grip portion 2 is suppressed.

By the way, the massage head 12 is provided with a pair of springs 21 for constantly urging the head case 13 on the joint surface with the head case 13, and a ball bearing 22 is arranged at the tip of the spring 21. On the other hand, the head case 13 has a pair of triangular projections 23 on the joint surface with the massage head 12 for engaging and disengaging the ball bearings 22. The pair of protrusions 23 are evenly arranged at four points on the joint surface. And massage head
The spring 12 holds the head case 13 with a predetermined pressure contact force by the spring 21, and at the same time, it is rotatably supported by the ball bearing 22. When the massage head 12 is rotated, the ball bearing 22 moves smoothly until it hits the protrusion 23, and then the protrusion 23 is retracted inward of the massage head 12 against the urging force of the spring 21.
Get over the tapered surface of. At this time, the ball bearing 22 engages with the valley portion formed between the pair of protrusions 22. When the massage head 12 is further rotated, the ball bearing 22 escapes from the valley portion as described above. As described above, since the massage head 12 rotates in four steps every 90 °, the massage head 12 can be rotated in a desired direction according to the location of the affected area, and a massage can be performed in a comfortable posture.

[0012]

According to the present invention, the ring-shaped massage head is held by the spring in the head case or the head case cap with a predetermined pressure contact force, and at the same time, is rotatably supported by the ball bearing.
Further, as the massage head is rotated, the ball bearing is engaged with and disengaged from a plurality of recesses formed in the head case or the head case cap, so that the massage head rotates in a stepwise manner in several steps. As a result, no matter where the affected area to be massaged is, the direction of the massage head can be changed according to the location of the affected area, so that the user can massage in a comfortable posture. Moreover, since this massage head rotates in a nodal manner, the direction of the head does not unexpectedly change during the massage.
