DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massage machine.

[0002]

2. Description of the Related Art In general, a massage machine is provided with a pair of treatment elements mounted on a rotationally driven kneading shaft with respect to the human body in the front-back direction (chest, back direction), up-down direction (neck, waist direction) and sideways. By performing compound movement in the direction (neck, shoulder direction),
Massage operations such as massaging and beating are realized.

[0003] As a conventional example of such a massage machine,
Some have the configuration as shown in FIGS. 6 and 7. That is, this massage machine has a pair of treatment elements 1
a, 1b, a kneading shaft 6, a width shaft 10, a hitting shaft 7, a vertical shaft 13 and the like. Each shaft is driven to rotate by a drive source (not shown). The treatment element 1 has a cylindrical shape and is rotatably attached to the arms 2 and 2. The arms 2, 2 are fixed to the housings 3, 3.

The pair of housings 3 and 3 and the pair of side plates 9 and 9 are mounted on the kneading shaft 6 substantially symmetrically. The housing 3 is rotatably disposed on the outer periphery of the eccentric inner race 4 via a bearing 5. The eccentric inner race 4 is fitted externally to the kneading shaft 6 so as to be eccentric, and can be moved in and out in the axial direction, is fixed in the circumferential direction, and can rotate integrally with the kneading shaft 6. For this reason, the treatment element 1 operates while drawing a composite trajectory by the rotation of the kneading shaft 6. In addition, in the case of performing the kneading operation, in addition to the above operation, the rotation of the kneading shaft 6 is slowed or accelerated by an elliptical gear or the like, so that the treatment element 1 operates slowly when pushing and when the treatment element 1 pulls, it operates fast. Like that. The side plate 9 is disposed on the side surfaces of the housing 3 and the eccentric inner race 4 and is rotatably attached to the kneading shaft 6. The side plate 9 has a through screw hole in the axial direction of the kneading shaft 6.

[0005] The width shaft 10 is threaded in opposite directions on both left and right sides, and the through screw holes of the side plates 9 and 9 are screwed. That is, these through screw holes have a reverse screw relationship, and the side plates 9, 9 move in opposite directions along the width shaft 10 with the rotation of the width shaft 10, whereby the pair of treatment elements 1 a , 1b move in the width direction. Hitting shaft 7
Has a shape in which a pair of axially symmetric crank portions 7a and 7b are connected to a rotation center shaft 7c at the end. The rotation center shaft 7c is rotatably held. The hitting shaft 7 and the housing 3 are connected by a link mechanism 5, and convert the rotational motion of the hitting shaft 7 into a circumferential reciprocating motion of the treatment element 1 with the kneading shaft 6 as a fulcrum. That is, the crank portions 7a, 7b
However, since they are eccentric so as to be symmetrical with respect to the rotation center axis 7c, the phases of the reciprocating motions of the pair of treatment elements 1a and 1b are shifted by 180 °, and the operation is alternately performed.

The rotation center shaft 7c is connected via a coupling plate 11 to a strength shaft 12 parallel to the rotation center shaft 7c. Then, the beating shaft 7 is rotated by rotating about the strength shaft 12 (for example, ± 45 °), thereby turning the strength shaft 1.
2 can be moved around the axis. This beating shaft 7
The link mechanism 5 moves with the movement of the arm, and the treatment element 1 operates in the front-rear direction with the kneading shaft 6 as a fulcrum.

The vertical shaft 13 is rotatably mounted on a frame (not shown) on which the above-described mechanism is mounted. A pinion 14 is fixed to the vertical shaft 13, and a chair 23 is provided.
3 (see FIG. 3). And
By rotating the vertical shaft 13, that is, the pinion 14, the entire mechanism including the treatment element 1 moves up and down in accordance with the rotation direction.

[0008]

In the conventional massage machine, the rotary drive of the massaging shaft 6 to which the treatment element 1 is attached, the width adjustment between the treatment elements 1, the front and rear directions with respect to the human body of the treatment element 1, and the like. Driving in the vertical direction has been performed by a motor that is one driving source. For this reason, a belt for transmitting the power of the motor to the respective shafts, a clutch for connecting and separating the power, and the like are required, and there is a problem that the structure of the belt is complicated and the entire mechanism is enlarged. . In particular, when the above-mentioned mechanism is attached to the back of the chair, the back is swollen, which is not preferable in terms of interior. In addition, since there is only one drive source, if any one of the rotation direction of the shaft and the moving state of the treatment element 1 is determined, all other operating states are fixed. For example, while the treatment element 1 is moving in the neck direction, it can move only in the chest direction (the direction in which the amount of protrusion is large) in the front-rear direction. In order to move the treatment element 1 in the neck and back directions, a two-step operation is performed in which, after operating in the neck direction, the power is disconnected by a clutch or the like, the rotation direction of the motor is reversed, and the motor is moved in the back direction. Becomes In addition, when moving the position of the treatment element 1 during the massage, the massage may have to be interrupted in order to switch the rotation direction of the motor. In addition, since the trajectory of the treatment element 1 is limited by the elliptical gear and the inclination of the eccentric inner ring 4, the kneading operation is mechanically constant.

Therefore, the present invention has been made in view of the above circumstances, and has as its object to simplify the structure, reduce the size of the mechanism, and move the treatment element along an arbitrary trajectory. It is to provide a massage machine that can do it.

[0010]

According to the massage machine of the present invention, the driving source for operating the treatment element includes a front-rear driving source for operating the treatment element in the front-rear direction, and a width for operating the treatment element in the width direction. Drive source, and a vertical drive source for operating the treatment element in the vertical direction. The treatment element is controlled by a command from a control circuit that independently controls each drive source.
The present invention is characterized in that a massage operation moved in a dimensional direction can be performed.
