Description

[0001] MASSAGE DEVICE [0002]

The present invention relates to a massage device, and more particularly, to a massage device that is convenient to use and can massage a user's body.

In general, a massage device is used mainly for releasing muscles and for treating body pain by pressing or knocking on body parts such as back, arms, legs and the like. Massage devices are manufactured and sold in various sizes depending on the body part used.

Massage devices that are currently on the market include a back massage device that can be mounted on a chair and massage the back part intensively, a chair type massage device made of a chair type in which a user can sit, and a user holding a handle Portable massaging devices that can massage a desired body part are typical.

The backrest type massage device is constructed such that the oscillating body is coupled to the eccentric shaft of the motor so that the vibrating body vibrates at a constant position while using only the back or the waist portion intensively. Therefore, it is difficult for the user to massage the body parts other than the back or the back. It is bulky and inconvenient to move or store. The chair type massage device can massage various body parts of the user, but it is expensive and has a disadvantage of occupying a lot of installation space. The portable massage device is advantageous in that it is small in volume and easy to use, but the conventional portable massage device has a disadvantage in that the massage effect on the body part is poor.

For example, a massage device disclosed in Registration Practical Utility Model No. 0354756 (Jun. 30, 2004) has an massage rod reciprocating by a solenoid, and can hit the body part with an massage pad. However, such a conventional massage device can only hit the body part with the massage pad, so it is difficult to obtain a massage effect such as releasing the muscles.

As another example, a massage device disclosed in Registration Practical Utility Model No. 0469045 (Sep. 13, 2013) has a configuration in which a massage head having a plurality of massage protrusions rotates to stimulate the body. Such a conventional massage device has a small range of body parts that can be stimulated by a massage head, resulting in poor massage efficiency.

And a rotating cam coupled to the camshaft and eccentric to the camshaft being connected to the movable bottom plate to reciprocate the movable bottom plate while rotating the camshaft about a rotation center axis.
The method according to claim 1,
Further comprising: a power transmitting unit connecting the driving unit and the movable bottom plate conveying unit so that the driving force of the driving unit can be transmitted to the movable bottom plate conveying unit.
The method of claim 3,
Wherein the driving unit includes a driving unit that generates a driving force and a rotating shaft that receives the driving force from the driving unit so as to provide a rotating force to the rotating supporting unit,
Wherein the movable bottom plate transfer unit comprises: a camshaft rotatably installed in the housing; and a portion coupled to the camshaft and eccentric to the camshaft is connected to the movable bottom plate to rotate the camshaft about a rotation center axis, And a rotating cam reciprocating the plate,
Wherein the power transmitting portion includes a gear train connecting the rotation shaft and the cam shaft.
5. The method of claim 4,
Wherein the rotation shaft and the camshaft are arranged to be orthogonal to each other,
Wherein the gear train includes a rotating shaft worm provided on the rotating shaft and a camshaft worm wheel provided on the camshaft so as to be coupled to the rotating shaft worm.
The method according to claim 1,
The driving unit may include a driving unit that generates a driving force, a rotation shaft that receives the driving force from the driving unit so as to provide a rotational force to the rotating support unit and that rotates, A driving wheel coupled to the rotating shaft, and a belt connecting the driving wheel and the rotating supporting body.
The method according to claim 1,
And a guide roller rotatably coupled to a bottom surface of the housing and rolling in contact with the movable bottom plate.
