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 Generally, in a massage machine, massage is performed by a massager massaging and striking. In this case, the larger the amount of protrusion of the treatment element to the human body side, the greater the pressure with which the human body is pushed, and the user feels that the user is strongly massaged. In a conventional massage machine, there are a massaging operation and a tapping operation as massage methods performed by a massager, which are operated separately.

[0003]

Therefore, if the rubbing and tapping are simultaneously performed, the amount of protrusion of the treatment element is increased, and the treatment element is performing the kneading operation, although there is a special effect which has not been available in the past. The massager itself was able to perform only one motion, such as only rubbing motion when hitting and hitting motion when performing tapping motion.

Therefore, an object of the present invention is to provide a massage machine capable of simultaneously performing a hitting motion while a massager is performing a rubbing motion.

[0005]

SUMMARY OF THE INVENTION A massage machine according to the present invention includes a main drive source that causes a pair of massaging elements to perform a rubbing and tapping operation by rotationally driving a rubbing shaft and a tapping shaft. In a massage machine having a control circuit for controlling, the main drive source and the control circuit are configured such that the rubbing shaft and the tapping shaft are rotationally driven at the same time.

[0006]

According to the structure of the present invention, the treatment element can simultaneously perform the rubbing operation and the tapping operation. At this time, the treatment element is displaced while moving in and out of the orbit of the rubbing operation, and two effects of rubbing and tapping can be obtained. Further, since the treatment element is displaced in this manner, the amount of protrusion of the treatment element is larger than in the conventional case, and massage with a large pressing force can be performed.

When the vibration kneading operation (striking kneading operation) command according to the present invention is inputted from the operation input circuit 21, the control circuit 20 kneads the main driving circuit 2c and the clutch 6 with the rotation of the main driving source 2a. A command is given to transmit to the work shaft 2b and the beating shaft 23. As a result, as described above, the housing 9 and the massaging elements 7a, 7b arranged on the outer periphery of the eccentric inner ring 10 are moved cyclically in the front-rear direction by the rotation of the eccentric inner ring 10, and the coupling plate 14 is periodically moved repeatedly. As a result, the housing 9 oscillates around the outer periphery of the eccentric inner ring 10 and the displacements of the treatment elements 7a and 7b in the front-rear direction change periodically. As a result, as shown in FIG. 10, the treatment elements 7a and 7b are displaced while moving in and out of the orbit K of the kneading operation, and the kneading operation and the tapping operation are combined.

Further, from the operation input circuit 21, the treatment elements 7a,
The control circuit 20 sends a backward movement command to the human body 7b.

Move to. When a command to move the treatment elements 7a and 7b in the forward direction with respect to the human body is input from the operation input circuit 21 to the control circuit 20, the control circuit 20 causes the front-rear drive circuit 3c to move the front-rear drive source 3a in the reverse direction. To rotate the front-rear shaft 3b counterclockwise as viewed from the front-rear drive source 3a. As a result, the support plates 12a, ... Operate in the opposite direction, and the treatment elements 7a, 7b move in the front direction of the human body. If the treatment elements 7a and 7b are moved in the forward direction, massage with a large pressing force can be performed.

When a command to move the treatment elements 7a, 7b in the upward direction with respect to the human body is input from the operation input circuit 21 to the control circuit 20, the control circuit 20 causes the vertical drive circuit 4c to rotate the vertical drive source 4a. A command is given to rotate the vertical shaft 4b. As a result, the pinion 15 that meshes with the rack 16 rotates, the frame 1 rises upward in the human body, and the treatment elements 7a and 7b move upward in the human body. The downward movement of the treatment elements 7a and 7b with respect to the human body is such that the up-and-down drive source 4a, the up-and-down shaft 4b, and the pinion 15 rotate in opposite directions, the frame 1 descends, and the treatment elements 7a and 7b.
The downward movement of the human body of b is performed.

When a command to reduce the distance between the treatment elements 7a and 7b is input to the control circuit 20 from the operation input circuit 21, the control circuit 20 causes the width drive circuit 5c to rotate the width drive source 5a. Give a command to rotate. As a result, the pair of side plates 11, 11 screwed to the width shaft 5b in a reverse screw relationship move so as to approach each other. Along with this, the housing 9 and the eccentric inner ring 10 move in a direction in which they approach each other along the rubbing shaft 2b. This movement reduces the distance between the treatment elements 7a and 7b. Also, the treatment child 7
To increase the distance between a and 7b, the width drive source 5a and the width shaft 5b can be used.
By rotating in the opposite direction, the housing 9 and the like move in the directions away from each other along the rubbing shaft 2b, and the treatment element 7
The distance between a and 7b increases.

In the above description of the operation, each operation has been described individually, but the operation input circuit 21 causes a plurality of treatment elements 7a, 7a.
You may input the operation command of b simultaneously. In this case, the positions of the treatment elements 7a, 7b in the front-rear direction, the vertical direction, and the width direction can be changed while massaging (rubbing motion, tapping motion, tapping-rubbing motion). In this embodiment, the front / rear drive source 3a, the up / down drive source 4a, and the width drive source 5a are provided, but one drive source may be used in common. Further, although the rotary motor is used as the drive source, a linear motor or the like may be used.

[0020]

According to the massage machine of the present invention, it is possible to cause the treatment element to simultaneously perform a rubbing operation and a tapping operation. At this time, the treatment element is displaced while moving in and out of the orbit of the rubbing operation, and two effects of rubbing and tapping can be obtained. Further, since the treatment element is displaced in this manner, the amount of protrusion of the treatment element is larger than in the conventional case, and massage with a large pressing force can be performed. Therefore, there is an effect that the feeling of rubbing felt by the human body is further improved.
