Massage instrument having separate massage module {Massage Instrument Having Separated Massage Modules}

The present invention relates to a massage machine, and more particularly, to a massage machine configured to massage both sides of a user's body while a plurality of massage modules are separately installed left and right and move up and down independently.

In general, a massage chair includes a massage device for directly massaging the user's back, waist, and buttocks, and a controller for controlling the movement of the massage device. In the massage chair, a single massage device moves up and down and moves The user's body located on the path is being massaged while performing programmed movements.

However, a massage chair in which a single massage device moves up and down can only imitate a very simple motion compared to a person performing a direct massage, and has limitations in performing massage in response to various body sizes of users.

In order to solve this problem, in Japanese Patent Registration No. 4875969, two massage modules (sample devices) are installed separately on the left and right of the backrest of the massage chair, and each massage module is operated by a separate driving device. Disclosed is a massager configured to perform a massage function while moving up and down along a part, massage a user's back and waist in a wide range in a width direction, and implement various massage patterns.

However, since the conventional massage machine having such a left and right separate massage module is configured by simply dividing a single massage module into two, the configuration is complicated, and the massage range in the left and right width directions can be increased, but the massage module is divided back and forth. Since it cannot be moved in the direction, it is difficult to adjust the massage intensity according to the user's body or requirements.

Japanese Patent Registration No. 4875969 Japanese Unexamined Patent Publication No. 2007-29481 Republic of Korea Patent No. 10-1288415

The present invention is to solve the above problems, and an object of the present invention is to install a plurality of massage modules left and right separately, and each massage module is configured to massage both sides of the user's body while moving independently. In the massager, the configuration can be simplified, the massage module can be moved in a certain range in the forward and backward directions, so that the massage intensity can be adjusted according to the user's body or requirements, and various massage patterns can be implemented. It is to provide a massager having a module.
