Then, plate-like members 30 and 32 having elasticity are attached to both the support members 26 and 28 so as to extend in a direction orthogonal to the main shaft 6. In addition, in this embodiment, the bearing 1 is formed by the plate members 30 and 32.
It also serves as a retainer for 8 and 20.

Treatment plates 34 and 36 are attached to the plate members 30 and 32, respectively. Both treatment elements 34 and 36 have the same structure, and one treatment element 34 will be described with reference to FIG. This massager 34 is provided with two hemispherical kneading balls 38, 40.
40 is rotatably supported by a pair of locking members 44 and 46 attached to the plate member 30 with screws 42.

On the other hand, fulcrum grooves 48 and 50 extending toward the cam center B are formed in the support members 26 and 28. The fulcrum grooves 48 and 50 have an oval shape and are formed in the cam center B direction so as to penetrate the support members 26 and 28. Further, a swinging drive shaft 52 is rotatably supported by the main body 7 in parallel with the main shaft 6 via bearings 55a and 55b. A wheel gear 54 is integrally attached to substantially the center of the swinging drive shaft 52.

A worm gear 56 is meshed with the wheel gear 54. The worm gear 56 is connected in series to the worm gear 4 via a clutch mechanism 57 so that the rotation of the drive source 1 can be transmitted. There is. In the present embodiment, the clutch mechanism 57 is a one-way clutch that transmits the rotation in one direction of the drive source 1 but turns the rotation in the opposite direction into a free state.

The clutch mechanism 57 is not limited to this.
You may use the electromagnetic clutch etc. which can transmit / interrupt rotation by electromagnetic force. Further, the drive source 1 is not limited to a single motor, but separate motors may be provided for the main shaft 6 and the swinging drive shaft 52, respectively. Further, in this embodiment, the diameter ratio between the wheel gear 4 and the wheel gear 54 is set to about 2.7: 1.

On the other hand, the oscillating drive shaft 52 has a second eccentric cam centered on eccentric centers D and E which are eccentric to the center C of the oscillating drive shaft 52 by a predetermined amount on both sides of the wheel gear 54. 58 and 60 are integrally formed. The eccentric directions of the second eccentric cams 58 and 60 are opposite to each other, that is, the phases thereof are different by 180 degrees. The second eccentric cams 58 and 60 are slidably inserted in the fulcrum grooves 48 and 50, respectively.

Two sets of mounting plates 62 and 64 are integrally mounted on the main shaft 6 on both outer sides of the support members 26 and 28, perpendicularly to the main shaft 6. Then, the mounting plates 62, 6
4 have six support shafts 66, 6 parallel to the main shaft 6, respectively.
8 (only a part of which is shown) is bridged at a position equally divided on a circle centered on the main shaft 6. Also, this support shaft 6
Rollers 70 having central protrusions and rollers 72 having both sides protruding are alternately and rotatably attached to the rollers 6 and 68, respectively.

Next, the operation of the massage machine of this embodiment described above will be described. First, when the drive source 1 is rotationally driven, the main shaft 6 is rotated via the worm gear 4 and the wheel gear 8. With the rotation of the main shaft 6, both the first eccentric cams 10 and 12 rotate, and the cam center B of both the first cam portions 14 and 16 makes a conical movement around the center A of the main shaft 6. ..

The support members 26 and 28 are also provided at the cam center B.
However, the rotation is restricted by the second eccentric cams 58 and 60 inserted into the fulcrum grooves 48 and 50. At this time, both the second eccentric cams 58 and 60 relatively slide in the fulcrum grooves 48 and 50.

By the movement of the support members 26, 28, the massaging elements 34, 36 move in a circle according to the eccentricity L on a plane where the central points of the massaging elements 34, 36 face each other in a "C" shape. I do. Moreover, when the treatment elements 34, 36 are most protruded, the distance between the treatment elements 34, 36 is narrowed, and
Both treatment elements 34, 36 are in the shape of an inverted "C". Also,
When it is most retracted, the interval is widened, and both treatment elements 34, 36 are in the shape of "C". A massage operation is performed by the movements of both treatment elements 34 and 36.

Further, the main shaft 6 is rotated by the clutch mechanism 5
7, through the worm gear 56 and the wheel gear 54, the speed is increased and transmitted to the swing drive shaft 52. When the oscillating drive shaft 52 is rotated, both the second eccentric cams 5 are also rotated.
8, 60 are rotated around the swinging drive shaft 52.
Along with this, both the second eccentric cams 58, 60 rotate in a state of being eccentric with respect to the center of the swinging drive shaft 52, relatively sliding in the fulcrum grooves 48, 50, Support member 2
6, 28 are swung about the center B of the cam.

By this swinging motion, a swinging motion centering on the cam center B is also added to the treatment elements 34 and 36, so that both treatment elements 34 and 36 perform a striking movement. Besides, both second
Since the eccentric cams 58 and 60 are out of phase with each other by 180 degrees,
Both treatment elements 34 and 36 alternately perform the swing motion. In addition, since the rotation of the main shaft 6 is accelerated and the swing motion is transmitted to the swing drive shaft 52, the massaging elements 34 and 36 are provided.
While performing one circular motion, a plurality of times, in this embodiment,
Approximately 2.7 swing motions are added, and along with the rubbing motion,
A striking exercise is performed.

On the other hand, when the rotation direction of the drive source 1 is opposite to the above-mentioned rotation direction, the clutch mechanism 57 is in a free state, and the main shaft 6 rotates in the swinging drive shaft 52.
Is not transmitted to. Therefore, only the main shaft 6 is rotated, and due to the rotation of the first eccentric cams 10 and 12, both the massaging elements 34 and 36 perform only a kneading motion as described above.

On the other hand, as the main shaft 6 rotates, the mounting plate 62,
64 also rotates, and accordingly, the rollers 70 and 72 revolve around the main shaft 6. Roller massage is performed by the revolution movement of the rollers 70 and 72. As described above, in the massage machine of the present embodiment, the second drive shaft 52 for swinging is provided with the second eccentric cams 58, 60, and the swinging motion is added to the supporting members 26, 28 to rub the massaging elements 34, 36. And make a beating motion. Further, the rollers 70 and 72 are rotated around the main shaft 6.

Therefore, it is possible to arrange the rollers 70, 72 provided on both outer sides of both the support members 26, 28 at a distance of about the shoulder width of a person. Therefore, it is possible to massage the affected part such as the nape of the neck with the massagers 34 and 36, or to place the affected part such as the sole side of the foot on the rollers 70 and 72 to perform the roller massage.

That is, since the rollers 70 and 72 can be arranged close to the outer sides of the supporting members 26 and 28, the apparatus can be downsized, and a kneading and tapping motion and roller massage can be performed. Can be configured.
In addition, the distance between the rollers 70 and 72 can be set to a distance in which both feet having a shoulder width are slightly opened in a comfortable state.

Since the plate-shaped members 30 and 32 have elasticity, the plate-shaped members 30 and 32 are elastically deformed even if a muscle or the like is sandwiched between the massaging elements 34 and 36 and the mounting plate 62. So you can continue the massage without feeling any pain. In the present embodiment, the second eccentric cams 58, 60
Although the supporting members 26 and 28 are swung directly by the above, instead of this, a lever swung by the second eccentric cams 58 and 60 is provided, and one end of this lever is engaged with the fulcrum grooves 48 and 50. Alternatively, the support members 26 and 28 may be configured to swing.

The present invention is not limited to such embodiments as described above, and can be carried out in various modes without departing from the scope of the present invention.
