DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type massage machine for massaging a treatment site such as a shoulder, a back, and a waist while a user is sitting.

[0002]

2. Description of the Related Art There is a chair-type massage machine (10) in which a user sits down and receives a massage of the neck, shoulders, back and waist. As shown in FIGS. 1 and 2, the massage machine (10) is configured by disposing a massage unit (30) on a backrest (13) of a chair (11) so as to be able to move up and down. 1 and 2
Is related to the massage machine (10) of the present invention,
Since the structure of the massage unit (30) is the same as the conventional one except for a part of the structure, a description will be given with reference to these drawings.

[0003] The massage unit (30) is attached to a guide rail (18) provided inside the backrest (13) via rollers (31) and (31), and is rotated by a motor (21). The backrest (13) is moved up and down by the screw thrust of (22). In the massage unit (30), a pair of left and right swing arms (43) and (43) are provided so as to be operable three-dimensionally in left and right, up and down, and back and forth, and each swing arm (43) and (43) At the tip of

2) Each of the free ends of (42) is provided with a kneading ball (41) (41).

In the massage machine (10) having the above-mentioned mechanism, the swing arm (43) (43) is driven, and the massage unit (30) is moved up and down while moving the right and left kneading balls close to and away from each other, so that the treatment can be performed. Rolling massage is applied to the entire upper body from the shoulder to the back and waist of the patient, or the massage unit (30) is lifted or stopped at a treatment site desired by the user, and partial massage is performed. There is also a massage machine that performs automatic programming massage combining these massages.

[0005]

The treatment arm (42) is urged by a spring (82) such that the upper kneading ball (41) protrudes forward. However, the urging force is
(41) When the (41) is not in contact with the user, the upper massaging ball (41) protrudes forward. Therefore, when the upper and lower massage balls (41) (41) hit the user, the treatment arm
(42) rotates with respect to the swing arms (43) and (43) in accordance with the unevenness from the shoulder to the waist so that both massage balls always contact the user at the same time.

This mechanism is effective when massaging a treatment site such as a relatively flat back and waist of a user. However, when massaging the shoulder, it is desirable to protrude the upper massaging ball (41) forward and press down from the ridge portion of the shoulder, but the upper massaging ball (41) is moved forward. Since the position cannot be fixed in the protruded state, a sufficient pressing force can be applied to the shoulder to perform massage and the massage effect is small.
