Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable massage machine.

[0002]

2. Description of the Related Art Conventionally, there has been provided a chair provided with a treatment element for hitting or rubbing a shoulder or back on a backrest portion of a chair. Also,
There is also a massage machine in which a treatment element is provided on the upper surface of the bed.

[0003]

However, there has been a problem that these massage machines are large in size and expensive.

Accordingly, the present invention provides a portable massage machine whose structure is easy and which can be expected to have a therapeutic effect.

[0005]

According to a first aspect of the present invention, there is provided a massage machine comprising: a carriage reciprocating on a base in a front-rear direction;
Moving means for reciprocating the cart, a pair of treatment elements attached to a rotating shaft arranged on the cart, and rotating means for rotating the rotating shaft, causing the cart to reciprocate by the moving means. In addition, the pair of treatment elements are rotated.

According to a second aspect of the present invention, in the massage machine according to the first aspect, the treatment element has a columnar shape, a plurality of protrusions protruding from a peripheral surface thereof, and the rotating shaft has a cylindrical shape. The center of the treatment element is provided at an eccentric position.

[0007] A third aspect of the present invention provides the massage machine according to the first aspect, wherein a driving means for driving the moving means and the rotating means is shared.

According to the massage machine of the first aspect, a person who wants to receive treatment puts the massage machine on a floor or a bed, and lies on his / her back on it. Then, while the carriage is reciprocated by the moving means, the pair of treatment elements are rotated to receive a back and shoulder massage. Also,
Alternatively, the massager can be attached to the back of a chair, and the person who wants to be treated can lean on the chair and receive a shoulder or back massage.

In the massage machine according to the second aspect, since a plurality of protrusions protrude from the peripheral surface of the treatment element, the effect is enhanced when a massage is performed by the treatment element. In addition, since the rotating shaft is provided eccentrically, the treatment element rotates while moving up and down, so that the person receiving treatment feels rubbed by this treatment element.

In the massage machine according to the third aspect, since the moving means and the driving means for the rotating means are commonly used, the structure can be simplified and the cost can be reduced.

A rear axle provided at the rear of 4d, and a pair of left and right rear wheels 32, 32 are provided at both left and right ends thereof.
Thereafter, the wheels 32, 32 move in the grooves 14, 14. Further, the rear wheels 32 are rotatable with respect to the rear axle 30.

Reference numeral 34 denotes a motor provided at the front of the bottom plate 24a of the truck 24. The rotating shaft 36 of the motor 34 passes through the left plate 24c, and a driving gear 38 is provided at the tip thereof. Have been. This motor 34 is connected to the PC board 22.

Reference numeral 40 denotes a front gear provided inside the left front wheel 28 and meshes with the drive gear 38. Further, the front gear 40 is movable in the rack 16. A front gear 40 is also provided inside the right front wheel 28 and meshes with the right rack 16.

Reference numeral 42 denotes a rear gear provided inside the left rear wheel 32. This rear gear 42 meshes with the drive gear 38 via the transmission gear 44. In addition,
The rear gear 42 does not mesh with the rack 16.

Reference numerals 46 and 48 denote fir balls as treatment elements attached to the front axle 26, that is, the fir shaft. The fir balls 46 and 48 have a columnar shape, that is, a shape like a car tire, and a plurality of protrusions 50 protrude from a peripheral surface thereof. The fir balls 46, 48 are formed of rubber. Furthermore, a pair of fir balls 4
6 and 48 are attached at positions eccentric to the front axle 26 (see FIG. 5), and are attached in a C-shape when viewed from a plane (see FIG. 4).

Reference numeral 52 denotes a remote controller which is attached to the PC board 22 and controls the massage machine 10. The remote controller 52 has a main switch 5 for turning on / off the massage machine 10.
4 and a speed adjustment switch 56 for adjusting the speed.

Reference numeral 58 denotes an outlet cord for supplying power to the PC board 22.

Reference numeral 60 denotes a lid of the base 12 made of a synthetic resin. On the upper surface, long holes 62 and 64 for exposing a pair of fir balls 46 and 48 are provided. Lid 6
0 is screwed to the base 12.

Reference numeral 66 denotes a cloth cover made of cloth for covering the pair of fir balls 46, 48 exposed from the cover 60.

The use state of the massage machine 10 having the above configuration will be described.

As shown in FIG. 6, the massage machine 10 is placed on the floor, and the person to be treated lies on his / her back on it. In this case, the massage machine 10 is arranged so as to come to the back part of the person who wants to receive the treatment.

The main switch 54 of the remote controller 52 is turned on.
In this state, the motor 34 rotates, and the driving gear 38 attached to the rotating shaft 36 of the motor 34 rotates, and moves rearward along the rack 16. In this case, the front wheel 2
8. The rear wheel 32 moves along the groove 14.

When the drive gear 38 rotates, the transmission gear 44
Also rotates, and the rear gear 42 rotates. When the rear gear 42 rotates, the rear axle 30 also rotates, and the pair of fir balls 46, 4
8 also rotates. In this case, the rotation directions of the rear axle 30 and the rear wheel 32 are reversed, but since the rear wheel 32 is rotatably disposed with respect to the rear axle 30, the rotation direction is opposite. However, the rear wheels 32 rotate with the movement of the carriage 24.

When the rear axle 30 rotates, the pair of fir balls 46 and 48 rotate as described above. In this case, since the rear axle 30 is mounted at an eccentric position, the fir balls 46 and 48 are vertically moved. The person being treated is in contact with the fir balls 46, 48 via the cloth cover 66, so that the person receiving the treatment feels as if he or she is receiving a massage. Also, a pair of fir balls 46,
Since 48 is provided in a C-shape on a plane, there is also a fir effect in the left-right direction.

The fir balls 46 and 48 are mounted on the cart 2
Since the position of the rack 16 moves together with the position 4, the position of the rack 16 is moved to the back of the person who wants to be treated, not a fixed position, but a fir effect. Furthermore, fir ball 4
6 and 48 are formed of rubber, and a plurality of projections 50 project from the peripheral surface thereof, so that the projections 50 can further enhance the fir effect.

When the carriage 24 moves from the front to the rear of the rack 16 and the rear end of the carriage 24 hits the rear wall 24, a load current larger than a normal load current is applied to the motor 34. Flows. Therefore, the PC board 22 detects this, and reverses the rotation direction of the motor 34. This allows
The carriage 24 moves from the rear wall 24 toward the front wall 18 this time. When the vehicle again hits the front wall 18, the rotation of the motor 34 is reversed, and the motor 34 is further moved in the direction of the rear wall 20. Thereby, the carriage 24 can reciprocate in the front-rear direction.

The moving speed of the truck 24 and the fir balls 46,
The rotation speed 48 is adjusted by adjusting the rotation speed of the motor 34 by the speed adjustment switch 56.

In the above description, the massage machine 10 is used by placing it on the floor as shown in FIG.
By attaching the massage machine 10 to the backrest of the chair 62 in the up-down direction as shown in (1), the back of the person sitting on the chair can be massaged.

[0033]

As described above, in the massage machine of the present invention, since the treatment element moves while rotating, the person who puts his back on this massage machine can obtain a massage effect by the treatment element.
