Can rub the local area of the body with a strong pressing force, and the massaging balls 32 on the low side can be rubbed lightly with a weak pressing force as compared with the high side, so that the left and right sides facing each other can be rubbed. On the rotating disk 3, the massage of strength and the massage of rolling are performed.

[0010]

1 to 4 show an embodiment of a portable rolling massage machine according to the present invention.

1 and 3, the massage machine is provided with a main body case 1 and a pair of left and right rotating disks 3 each having a rubbing ball 32 and a drive mechanism 4.

The main body case 1 has an opening 5 on its upper surface. For example, a plastic upper case 1a is brought into contact with a plastic lower case b and integrally connected by screws or the like. It is formed as an overhang.

The drive mechanism 4 supports a motor 7 and a reduction gear case 8 connected to the motor 7 on the inner bottom of the main body case 1 via vibration isolating rubbers 9 respectively.
Inside the worm shaft 10 driven by the motor 7
A pair of left and right worm wheels 11 meshing with the worm wheels 11 are built in, and the rotary drive shafts 12 are erected parallel to each other from the center of each worm wheel 11 toward the opening 5.

Accordingly, the pair of left and right rotary drive shafts 12 are rotatably driven in opposite directions through the worm shaft 10 and the worm wheel 11 by driving the motor 7.

A forward / reverse motor 7 is used as the motor 7. As shown in FIG. 2, the motor 7 can be turned on / off by a power switch 13 provided on the front side of the opening 5 on the upper surface of the main body case 1. The rotation direction can be arbitrarily changed by the forward / reverse switch 14.

A rotary disk 3 having an inclined upper surface 31 is fixed to the upper end of each rotary drive shaft 12 so as to obliquely intersect the rotary drive shaft core P at a predetermined angle. As shown in FIG. 1, the rotating disc 3 of FIG. 1 has a state in which the respective tilt axis Q is narrowed upward when the rotation phases are such that the lowest side ends 3a of the tilted upper surfaces 31 are closest to each other. It is attached to each rotary drive shaft 12 so that the inclined shaft cores Q diverge upward when they are in the rotation phase for the most separation.

The inclined upper surface 31 of each rotating disk 3 is provided with a plurality of concave portions 33 having an arc-shaped cross section at predetermined intervals along the circumferential direction. The hemisphere is fitted so that more than the hemisphere sinks and a part of the spherical surface protrudes so as not to come out.

The rubbing ball 32 is freely rotatably fitted with a ball 34 interposed between the rubbing ball 32 and the concave portion 33.

Further, a cover 18 made of a flexible cloth or the like is provided in the opening 5 of the main body case 1 with a rubbing ball 32.

[Operation of the embodiment]

In the portable rolling massage machine constructed as described above, the main body case 1 is placed on the floor, and the user can lie down or sit down to cover a part of the shoulder, waist or leg through the cover 18. Or use it by placing it on the massage ball 32 or holding the handle 6 with both hands, lifting up the entire main body case 1 and applying the massage ball 32 to a local part such as a thigh or a lower leg via the cover 18. Can be used.

In this use, when the motor 7 is started, the pair of left and right rotary drive shafts 12 rotate, and the left and right rotary discs 3
Turns relatively around each drive shaft center P while continuously changing the inclination direction of the inclined upper surface 31.

In this case, since a plurality of rubbing balls 32 are provided on the inclined upper surface 31 of each rotating disk 3, local parts such as shoulders and waist are sandwiched between the plurality of rubbing balls 32 on the left and right rotating disks 3. At the same time, each left or right rotating disk 3
It is pinched and rubbed between the upper massage balls 32.

Moreover, such a rubbing condition is caused by the inclined upper surface 3
Among the plurality of massaging balls 32 provided in 1, the massaging ball 32 located at the highest position on the inclined upper surface 31 rubs a part of the local area most strongly, and the massaging ball 32 located at the lowest position is light. Rubbing, the rubbing ball 32 located near the middle of the rubbing, changes the rubbing strength, such as rubbing at the intermediate strength, so that the rubbing effect can be enhanced and blood circulation is improved.

Further, since each of the rubbing balls 32 is freely rotatable, rubbing against the body can be carried out smoothly.
Problems such as pulling and breaking the cover 18 between the body 2 and a local part of the body are eliminated.
