Chair-type massage machine

Abstract

The invention provides a chair-type massage machine which comprises a backrest part, comprising a backrest plate supporting a user's body and inclining rearward from the right and left end part to a central part, and airbag support tables which is arranged in a recessed part recessedly provided at ends of right and left sides of the backrest part from the front of the backrest plate; and shoulder airbags respectively arranged at left and right airbag support tables. Therefore, the user's arms are integrally subjected to a relatively strong pressing therapy equal with a strength by manpower kneading. Even if the airbags at the arms of the pressing users is contracted, an uncomfortable feeling that the user's upper arms float through the airbags does not occur, and user' is embedded in a therapeutic component in the central part of the backrest part and is fully pressed. Even if the airbags repeatedly expand and contract, the chair-type massage machine can still rapidly carries out the continuous actions, and can be tightly packaged and easily transport and assemble.

Description

technical field [0001] The present invention relates to a chair-type massage machine provided with a mechanism for intermittently compressing a user's shoulders and upper arms from the side and rear by an expansion-contraction mechanism that expands or contracts by supplying and discharging compressed air. Background technique [0002] In the past, among the chair type massage machines, it is well known to have a reclinable backrest, seat, armrest, etc., in order to massage the waist, back, neck, buttocks, elbows, etc. A structure that uses compressed air to expand or contract with changes in air pressure. [0003] For example, in Japanese Patent Application Laid-Open No. 2008-49087, it is disclosed that there is a seat for the patient to sit on, a backrest for the patient to sit on the seat, and a backrest arranged on the backrest. In addition, a massage machine such as a treatment section of a treatment member protrudes toward the person to be treated. [0004] In additi...

Problems solved by technology

However, since the user's upper arm is pressed, the user's body is tilted by the air bag on the side of the central part of the backrest, and the upper arm is pressed by the air bags at the left and right ends of the backrest. There may be insufficient compression by the treatment part whenever the body is tilted

In addition, in order to arrange the air bag, the lateral width of the left and right ends of the backrest is widened, and it is difficult to pack the product compactly when shipping. In addition, the weight of the backrest itself becomes heavy. The problem of putting a load on the motor used to turn when turning in the direction

[0009] Furthermore, in Japanese Patent Laid-Open No. 2008-132036, a rotating mechanism that rotates a rotating plate provided with a treatment protrusion by an air bag is embedded in a recess provided on the left and right ends of the backrest, and the treatment protrusion presses the user. The structure of the side of the upper arm, but in the pressing from the left and right of the backrest through the treatment protrusion, even if the shape of the treatment protrusion is formed so small that it can be accommodated in the left and right of the backrest, although it can be obtained with the human hand. The effect is similar to that of finger pressure, but the effect similar to the kneading brought by human hands, that is, kneading is not enough
