Are arranged on the outer periphery of the second roller 13. 14
a and 14b are bearings 15 on the mounting base 2 and the drive shaft 6.
a, 15b, and a rotating shaft 16 of a second roller 13 is attached to an end via bearings 16a, 16b. 17
a and 17b have one end fixed to the housing 1 and the other end
A spring, which is a biasing means attached to a and b, gives the second roller 13 a feeling of elasticity. 18 is the drive shaft 6
, A second pulley 19 provided on the rotating shaft 16, a belt 20 for transmitting the rotation of the drive shaft 6 from the first pulley 18 to the second pulley 19,
The transmission means includes a first pulley 18, a second pulley 19, and a belt 20.

Next, the operation will be described. When the motor 4 is energized and the motor shaft 5 rotates, the drive shaft 6 also rotates and the key 8 rotates the first roller 3. Further, since the pulley 18 is attached to the drive shaft 6, it rotates simultaneously with the rotation of the motor 4, transmits the rotation to the pulley 19 via the belt 20, and the second roller 13 rotates.

The arms 14a, 14b to which the second roller 13 is attached are urged upward (toward the treatment site) by springs 17a, 17b, and the wrist, which is the treatment site, is moved to the second roller. 13, the second roller moves up and down in response to the force, thereby giving a sense of elasticity to the wrist.

In the embodiment, the springs 17a, 17a
b causes the arms 14a and 14b to move up and down,
The configuration in which the second roller 13 also moves up and down has been described. However, the present invention is not limited to this configuration. And the rotation shaft 16 of the second roller 13
One end of the spring may be attached to the spring.

The treatment element 12 shown in the embodiment is, for example, an abacus ball having a diameter of 13 mm and a thickness of 7.6 mm. Further, when the number of balls of the treatment element 12 is selected in a range covering an average human hand, considering the size of the palm of the human hand, the effective axial length is about 135 mm. In addition, when considering large hands such as foreigners and athletes, it is about 180 mm.
It is about 0 mm. Therefore, it is desirable to appropriately select the number of balls with reference to these. In the embodiment, the effective axial length is 135 mm, the number of balls is 17, and the play between the balls is 5.8 mm in total.

Further, the diameter of the first roller 3 is
Considering the curvature when a person holds his hand from the tip of 2 to the opposite tip, it is 1 if it is within the range of the average human hand.
It is about 00 mm. In addition, it is about 200 mm when considering a person with a large hand such as a foreigner or an athlete, and about 50 mm when considering for a woman. Therefore, it is desirable to appropriately set the diameter with reference to these. In the embodiment, the diameter of the treatment element 12 of 13 mm and the gap of 1 mm between the first roller 3 and the treatment element 12 are reduced in both directions to 72 mm (the diameter of the first roller 3 is 72 mm + 2 ×
(Diameter 13 mm of treatment element 12 + gap 1 mm) = 100 m
m). Further, the diameter of the second roller 13 was 33 mm as a diameter fitting the wrist.

The first roller 3 and the second roller 13
When the peripheral speeds of the treatment elements disposed on the outer peripheral portion of the hand vary greatly, a feeling of being caught or pulled by the palm may occur, and the comfort may be slightly inferior. Therefore, if the ratio of the number of teeth of the pulley is selected so that the circumferential speeds of the treatment elements of the two rollers are the same, massage can be performed more comfortably. In the embodiment, the diameter between the treatment elements 12 of the first roller 3 is 100 mm, and the treatment element 1 of the second roller 13 is
Since the diameter between the two was 33 mm, the ratio of the number of teeth between the pulley 18 and the pulley 19 was 1: 3. Thereby, the treatment element 12 of the two rollers can be rotated at substantially the same peripheral speed.

In the embodiment, the treatment element is formed in the shape of an abacus ball. However, the treatment element is not limited to this, and may be, for example, a spherical shape. In that case, for example, it is assumed that there are 10 spherical treatment elements having a diameter of 13 mm and the total play is 5 mm. Also,
The abacus ball-shaped treatment element is particularly suitable for massaging acupuncture points, meridians, and reflection bands due to its shape, and the spherical treatment element is suitable for giving the effect of massaging the pot and relaxing stiffness from its shape. . Also, an abacus ball shape and a spherical treatment element may be mixed and used.

Further, treatment elements of other shapes may be used alone or in combination. There are various ways to mix, such as every other, every two, the same number, etc.
No particular mention is made here.

Next, how to install a massage machine,
It may be used in the form of being placed on a desk, or attached to the tip of an armrest of a chair so that it can be used in a relaxed position while sitting on the chair. Further, it may be configured to be attachable and detachable so that it can be used according to the user's preference and life scene.

According to the present embodiment, since the first roller and the second roller having different diameters are provided, the entire palm and the wrist can be massaged simultaneously. In addition, since the first roller and the second roller are bilaterally symmetric, a single device can massage either the left hand or the right hand. Also,
If you have two for the left hand and the right hand, you can massage both hands at the same time. In addition, since the abacus ball shape is used for the treatment element, it is possible to massage the palm pot, the meridian, and the reflection band evenly and simultaneously.

[0021]

According to the present invention, since the first roller and the second roller having different diameters are provided, the palm and the wrist can be massaged effectively.

Further, since the urging means is provided on the second roller, there is a feeling of elasticity when the treatment site is placed, and the feeling of wearing on the wrist can be enhanced.

Further, since the rotational peripheral speed of the first roller and the rotational peripheral speed of the second roller are set to be the same, the feeling of the palm being pulled or pinched can be eliminated.
