Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a massage device that can be held in one hand and used to knead or pat one's own neck and shoulders.

[Conventional technology]

A massage device that can be held in one hand and used to hit or knead one's shoulder or neck is a massage device that has a tapping ball and is capable of a tapping action, or a massage device that has a holding part and massage balls that can perform a massaging action. equipment was traditionally used. However, there has never been a massage device that has a kneading ball and a kneading ball and allows the kneading and kneading actions to be performed at will.

[Problem that the invention attempts to solve]

When massaging the shoulders and neck, a tapping motion and a kneading motion, which applies strong pressure by pinching, are performed, but as can be understood from the different sensations received from these two motions, these motions are slightly different. It is also effective, and to be more effective, it is desirable to perform these actions alternately, and by doing so, the effect will be increased. However, since conventional massage devices can only perform either tapping or kneading, two massage devices are required to alternately perform the tapping and kneading operations, which requires a lot of expense.

This invention was created in view of the above circumstances, and includes:
To provide a massage device on a stand capable of performing continuous beating action of pounding balls and intermittent kneading action of kneading balls.

[Means for solving problems]

In order to achieve the above object, the present invention is a massager equipped with a gripping part at one end and an actuating part at the other end. It is equipped with a movable slide block, and a beater ball connected to the slide block via a beater rod and exposed from the main body. A swing block whose one end is pivotally connected to a moving plate, a shaft which is connected to the other end of the swing block via a one-way clutch and rotates intermittently in one direction, and a crank arm fixed to the shaft. a grooved lever into which a pin is loosely fitted and which swings; and a grooved lever connected to the grooved lever via a massage rod,
This massager is characterized by comprising massage balls exposed from the main body and a holding portion formed in the shape of a protrusion on the main body at a distance suitable for holding the shoulders, neck, etc. from the massage balls.

[Effect]

The rotational motion of the motor rotating shaft is transmitted to the slide block as reciprocating motion via the crank mechanism.
This reciprocating motion causes the striking ball to perform a striking action. On the other hand, the reciprocating motion of the slide block is transmitted through the reciprocating plate to the swinging arm as a reciprocating swinging motion, and the swinging motion of the swinging arm is directed in one direction to the shaft connected via the one-way clutch. This is transmitted as intermittent rotational motion, and the crank pin provided on the crank arm, which rotates together with the shaft that rotates intermittently, moves within the groove of the grooved lever, causing intermittent rocking motion in the lever, causing the massaging balls to move. performs intermittent rocking movements.

The reciprocating motion of the beating ball is at the same speed as the rotation speed of the electric motor. In addition, the intermittent motion in the intermittent rocking motion of the massage ball is the same number of times as the number of revolutions of the electric motor, and one large rocking motion is performed while repeating this intermittent motion more than 10 times. By sandwiching the shoulders, neck, etc. between these kneading balls and the holding part fixed to the main body, an effective kneading motion can be performed, but if you get tired of the kneading motion, you can change the direction of the main body. By doing so, it is also possible to perform a tapping action.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. The electric motor 2 with a speed reducer is fixed to a chassis 21, and an eccentric shaft 8 is press-fitted into the rotating shaft 7. Due to the action of the connecting rod 6 that connects the eccentric shaft 8 with a pin (not shown) provided at the lower end of the slide block 11, the rotation of the electric motor 2 with a reduction gear is transmitted as a reciprocating motion of the slide block 11. . A beating ball rod 9 and a reciprocating plate 12 are fixed to the slide block 11, and the beating ball rod 9 has a beating ball 3 fixed to its tip and is restrained by a hole in a guide 10 to reciprocate. In this way, the beating ball reciprocates at the same frequency as the rotational speed of the output shaft of the electric motor. On the other hand, the reciprocating plate 12 is provided with an elongated hole (not shown) extending perpendicularly to the reciprocating direction, and a pin 13 is inserted through this elongated hole. Via the pin 13, the reciprocating motion of the reciprocating plate 12 transmits a rocking motion to the rocking block 14. The rocking block 14 is connected to the shaft 16 via a one-way clutch 15.
The shaft 16 is supported by a bearing plate 22 fixed to a chassis 21 via a sliding bearing. Due to the action of the one-way clutch 15,
The oscillating movement of the oscillating block 14 is transmitted as an intermittent rotational movement of the shaft 16 in one direction. Crank arms 17, 17' are fixed to both ends of the shaft 16.
In addition, a coil spring 2 is attached to the boss portion of the crank arm 17'.
3 are placed on each other so that they are in slight contact with each other, and one end of the coil spring is fixed to the bearing plate 22, so that the shaft 1
Rotation of the coil spring 6 in one direction causes the coil spring 23 to be tightened, and rotation in that direction is reliably prevented. That is, the shaft 16 hardly rotates in a direction in which the one-way clutch 15 cannot effectively transmit rotation. In this way, the crank arms 17, 17' rotate intermittently in one direction, but the pins 18, 18' fixed to the crank arms 17, 17' are formed integrally with the massaging ball rod 20. Since the massaging ball lever 20 is engaged with the groove of the grooved lever 19 and is swingably supported by the chassis 21, the massaging ball lever 20, which has the massaging ball 4 fixed to its tip, undergoes intermittent rocking motion. I do. In this way, by holding the shoulders, neck, etc. between the holding part 5 fixed to the main body 1 and the massaging balls 4, it is possible to perform massage with a massaging effect. Note that 24 is a power cord, and 25 is a power switch.

[Effect of idea]

Since the massage device according to the present invention can perform kneading and tapping operations, it can perform more effective massage operations compared to conventional massage devices. Also, since the kneading motion includes subtle high-speed movements, muscle stiffness can be effectively cured. Furthermore, since the rotation speed of the electric motor can be changed using a changeover switch, the above-mentioned effects can be further enhanced.
