  The present invention relates to a chair type massage machine configured to swing a leg portion of a seated user to the left and right to enable swing massage on the entire leg portion.

  Conventionally, as a chair type massage machine having a footrest part with a massaging mechanism for a leg part of a human body, for example, vibration massage by a vibrator built in the footrest part or expansion / contraction by air supply / exhaust in an air supply / exhaust device There are those that perform pressing or pinching massage that is performed by inflating and contracting each inflatable and deflated bag while the deflated bag is placed inside a pair of left and right recesses formed on the footrest. The chair type massage machine provided with such a massage mechanism in the footrest part is configured to be able to locally massage the part of the leg part according to the user's desire.

  Furthermore, not only local massage of the legs in the footrest, but also a chair type massage machine that performs massage by rocking movement (so-called goldfish movement) that passively moves while loosening the legs as a whole. It is disclosed. For example, there is a chair type massage machine shown in FIGS. That is, as a chair body 1 of the chair type massage machine, a seat portion 6 including a seat portion 4 and a footrest portion 5 and a backrest portion 7 are provided with respect to a base frame 3 provided with a pair of left and right armrest portions 2. It is composed. The seat portion 4 is fixed to the base frame 3, the footrest portion 5 is supported on the front side of the seat portion 4 so as to be pivotable in the front-rear direction, and the backrest portion 7 is pivotable in the vertical direction while moving in the front-rear direction. Is provided.

  Of the seat portion 6 on which the lower body is placed, the footrest portion 5 on which the portion below the knee is placed is provided with a rocking massage mechanism 64 for massaging the lower body as shown in FIG. The rocking massage mechanism 64 is for massaging the lower body by reciprocating a foot receiving member 65 that receives, for example, an ankle portion of both feet, in the left-right direction by a driving device 66, thereby shaking both feet to the left and right. When the foot support member 65 reciprocates in the left-right direction, the lower half of the body swings left and right (so-called goldfish movement) around the waist supported by the seat 4, and the foot base is centered. Get twisted. For this reason, a twisting motion is also given to the waist. In this way, by providing the rocking massage mechanism 64 in the chair body 1, almost the entire lower body of the user seated on the chair body 1 can be rocked and massaged.

  As shown in FIGS. 24 and 25, the footrest portion 5 is connected so that the angle of the footrest portion 5 can be adjusted from below horizontal to above horizontal. In such a horizontal posture and an upward posture, The position becomes different from front to back. For this reason, by selecting the posture of the footrest portion 5 according to the height of the user, the foot support member 65 can be set at a position suitable for extension.

When the footrest portion 5 is in a horizontal posture, the degree of tension on the back side of the knee is relatively weak and a relaxed posture, and when the footrest portion 5 is in an upward posture, It is said that the back side is stretched strongly and becomes a tense posture.
