Description

  The present invention relates to a chair type massage machine that treats the body of a user who is seated on a seat, and in particular, a chair type massage machine that can press the body of the user from the outside and treat the body from the rear. About.

  A massage machine such as a chair type or a mattress type is widely known. For example, a chair-type massage machine has a seat portion and a backrest portion, and has a structure in which a treatment element for performing treatment of the human body is provided in the backrest portion, and drives a plurality of built-in motors. In general, the combination allows the treatment element to selectively perform a plurality of actions (for example, a kneading action, a hitting action, a change in treatment area, etc.). Such a massage machine is capable of stimulating the back of the user's torso mainly by pressing the treatment element against the back of the torso of the user.

  However, in the conventional massage machine as described above, there is a problem that only the back portion of the torso of the user can be treated, and the range in which treatment is possible is small.

  The present invention has been made in view of such circumstances, and treats a body part that could not be treated with a conventional massage machine, such as the side of the torso of the user and the sides of the waist and thigh. An object of the present invention is to provide a massage machine that can expand the range in which treatment can be performed as compared with the prior art.

  In particular, an object of the present invention is to provide a chair type massage machine that can press the body of the user from the outside and can treat the body from the rear.

Yes.

  In the human body, so-called acupuncture points are scattered throughout the entire body, and by stimulating the acupuncture points, effects such as recovery from fatigue and improvement of blood circulation can be obtained. Therefore, it is desirable to have a structure that can give stimulation to acupoints other than the back of the trunk. In the chair type massage machine according to the present invention, it is possible not only to treat the torso of the user from behind with the mechanical massager, but also to the torso of the user with the first pneumatic massager. By pressing from behind, the treatment can be performed with an action different from that of the mechanical massager, and the upper arm and shoulders (including shoulder fins) of the user from the left and right outer sides by the second pneumatic massager. It is also possible to press and treat. Therefore, the range in which treatment can be performed can be expanded as compared to the conventional case, and various treatment actions can be exerted, so that the treatment effect can be further improved. Furthermore, by pressing the upper arm and shoulder from the left and right outwards, the posture of the user can be prevented from shaking left and right, so the mechanical massage device and the first pneumatic massage device are driven in this holding state. In this case, it is possible to give a stimulus to an appropriate position of the torso of the user and improve the treatment effect.

  In addition, the mechanical massager may be disposed at the center in the left-right direction in the backrest, and the first pneumatic massager may be disposed on the left and right outwards with respect to the mechanical massager. .

  By setting it as such a structure, the whole back part of a user's trunk | drum can be treated appropriately. That is, a portion near the spine that is relatively strong against physical stimulation in the torso of the user can be effectively treated by the mechanical massager. Further, the side of the human torso has less muscles than the portion near the spine and is sensitive to stimulation. Therefore, when the air bag is inflated and deflated to treat the portion near the side of the body of the user, it is possible to appropriately treat the portion with appropriate stimulation.

  The chair-type massage machine according to claim 2, wherein the second pneumatic massager is disposed on the left and right outwards with respect to the first pneumatic massager.

  Further, the backrest part may have a guide extending in the vertical direction so as to guide the ascending / descending operation of the mechanical massager passing between the left and right first pneumatic massagers.

  In this way, by using the guide for guiding the lifting and lowering of the mechanical massager used in the conventional massage machine for the massage machine according to the present invention, the parts can be shared between the conventional product and the product of the present invention. The product development cost can be reduced.

  The first pneumatic massager may be configured to treat the side of the torso of the user seated on the seat.

  The backrest may include a third pneumatic massager that inflates an air bag by supplying air and presses an upper part of the shoulder of the user.

  By adopting such a configuration, in addition to the back and sides of the torso of the user, the upper part of the shoulder of the user can be treated, and the range where treatment can be further expanded. It becomes possible. In addition, since the posture of the user can be prevented from moving up and down by pressing the upper part of the shoulder with the third pneumatic massager, the mechanical massager and the first pneumatic massager in this holding state. When the device is driven, it is possible to give a stimulus to an appropriate position of the torso of the user and improve the treatment effect.

  According to the chair type massage machine according to the present invention, the body of the user can be pressed from the outside, and the body can be treated from the rear.
