Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a chair-type massage machine capable of pinching and rubbing the vicinity of a shoulder of a user, and more specifically, to a user. The treatment finger contacts the affected part of the patient. 2. Description of the Related Art There are known various massage devices for eliminating stiffness by pressing and stimulating a person's shoulder, waist and the like. These devices can be classified by type into chair type, bed type, and handy type.
An electrical stimulation type can be mentioned. Among these devices, a chair type massage machine (90) as shown in FIG.
Is widespread. This massage machine (90) is a chair (9
Two arms (93) and (93) protrude from the backrest (92) of (1), and the distal end of each arm (93) (93) has a treatment finger ( 94) (94). Arm (93) (93)
Is connected to an arm drive unit (not shown) provided inside the backrest (92). The massage operation by this massage machine can be divided into a beating operation and a kneading operation. The beating operation is an operation in which the treatment fingers (94) and (94) move in the up and down direction due to the vertical movement of the arms (93) and (93) and hit the user's shoulders and the like. The treatment fingers (94) and (94) move in the horizontal direction due to the left and right movements of () and (93), and are movements of rubbing the neck and the like of the user. [0003] The shoulder massaging operation by hand involves grasping the multi-finger side from the index finger to the little finger and the vicinity of the shoulder with the thumb. More specifically, the multi-finger side is moved from above or above the shoulder. This is an operation of pressing the acupressure point near the spine of the user with the thumb against the front part, and such an operation cannot be performed by the massage machine. That is, with the conventional massage machine, it is not possible to obtain a massage sensation that is close to a manual shoulder kneading operation. [0004] It is an object of the present invention to provide a massager that performs a massage similar to a manual shoulder kneading operation, and that effectively acupressures the acupoints on the back. [0005] In order to solve the above problems, the present invention provides a treatment finger (1) attached to the tip of an arm (20) protruding from a backrest (13) of a chair (12). 70) is a chair-type massage machine that can massage and pinch the vicinity of the shoulder of the user (80), the treatment finger (70), by the treatment finger drive unit (74),
A first treatment finger (72) and a second treatment finger (73) that move up and down to move toward and away from each other;
The treatment finger (72) has a first contact portion (72b) in contact with the user (80) at the tip thereof, and the treatment patient (80) is attached at the tip of the lower second treatment finger (73). A second contact portion (73b) for contacting the
The swing transition surface of the first contact portion (72b) and the second contact portion (73b)
Swing transition surfaces are spaced apart from each other, and the first contact portion
The contact area of (72b) with the affected part of the user (80) is formed larger than the contact area of the second contact part (73b) with the affected part of the user (80). Specifically, the first contact portion (72b) is arranged so as to contact the upper portion or the upper portion of the shoulder of the user (80) with the front portion, and the second contact portion (73b) is provided. , The spine of the user (80)
(83) Deploy so as to stimulate acupoints (84) in the vicinity. That is, the first contact portion (72b) corresponds to the multi-fingered side when the shoulder is manually rubbed, and the second contact portion (73b) corresponds to the thumb when the shoulder is rubbed manually. [0007] The treatment finger (70) having the above-mentioned structure is moved to the first contact portion (72b).
Is applied to the upper part or the upper part of the shoulder (81) of the user (80) to the front part, and the second contact part (73b) is applied to the acupoint (84) near the spine (83) of the user (80). Then, when the treatment fingers (72) and (73) are swung, the swing transition surfaces of the contact portions (72b) and (73b) are different. Further, as shown in FIG. 9, a force F in the torsional direction is also applied, and the acupoint (8) near the spine (83) is applied.
4) can be stimulated more effectively. Also, by changing the contact area of the first and second contact portions (72b) (73b) with the diseased portion, the first and second contact portions (72b) (73b) are brought into contact with the diseased portion with the same force. However, the first contact part (72b) has a smaller treatment pressure on the affected part than the second contact part (73b) because of a larger contact area with the affected part, and the second contact part (73b)
Because the treatment pressure increases due to the small surface area,
The key point (84) can be effectively held down. An embodiment of the present invention will be described. In the chair type massage machine (11) shown in FIG. 1, the arrow F side is the front, and the arrow R is the right. The “vertical plane” means a vertical plane parallel to the front-rear direction.
