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, it is necessary to move the position of a treatment element according to a part to be massaged. For example, in a massage machine having a treatment element on the back of a chair, the treatment element is moved up and down with respect to the human body to massage the neck and waist. Also, the width between the treatment elements should be narrow at the neck and wide at the shoulder. further,
The treatment child is moved in the front-back direction (chest, back direction) with respect to the human body according to the user's preference. In this case, the larger the amount of protrusion toward the human body, the greater the pressure with which the treatment element presses the human body, and it feels as if the massager is strongly massaged.

[0003] In the conventional massage machine, the massage and hitting operations of the treatment element, the width adjustment between the treatment elements, and the driving of the treatment element in the front-rear direction and the vertical direction (the neck and waist directions) with respect to the human body are performed by one operation. driving source axis attached to more rotary driven treatment elements (the motors), a timing belt for transmitting power to a different axis for causing the driving of the width adjustment and the like, connect the power-
This has been achieved by a clutch that separates.

[0004]

However, in the conventional example, since there is only one motor as a driving source, if any one of the rotation direction of the shaft or the moving state of the treatment element position is determined, other operations are performed. All states are fixed. For example, while the treatment element 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. Therefore, in order to move the treatment element in the neck and back directions, after moving the treatment element in the neck direction, the power is disconnected by a clutch or the like, the rotation direction of the motor is reversed, and the treatment element is moved in the back direction. Must be operated in two stages. In addition, in order to move the treatment element position during the massage, the massage may have to be interrupted to switch the rotation direction of the motor.

Accordingly, an object of the present invention is to provide a massage machine which can freely select and perform a plurality of operations at the same time.

Commands are given to c, 3c, 4c and 5c.

Next, the operation of the massage machine will be described. When a kneading operation command is input from the operation input circuit 21 to the control circuit 20, the control circuit 20 switches to the main drive circuit 2c.
And a command to transmit the rotation of the main drive source 2a to the kneading shaft 2b. Thereby, the main drive source 2
a rotates, and the eccentric inner ring 10 fixed to the kneading shaft 2b rotates. As shown in FIG. 5, the eccentric inner ring 10 changes its diameter from the axis of the kneading shaft 2b due to its rotation, and the housing 9 and the treatment elements 7a,
7b is moved periodically in the front-rear direction to perform massage by a kneading operation.

When a hitting operation command is input from the operation input circuit 21 to the control circuit 20, the control circuit 20
c and a command to the clutch 6 to transmit the rotation of the main drive source 2 a to the hitting shaft 23. Thereby, the main drive source 2
a rotates, the pulley 17a, the timing belt 18a,
Pulley 17b, timing belt 18b, pulley 17c
Is driven, and the hitting shaft 23 rotates. When the hitting shaft 23 rotates, the one ends 14a, 14a of the coupling plates 14, 14 move periodically along the locus 22 drawn by the crankshaft portions 23a, 23b around the hitting shaft 23, as shown in FIG. I do. Accordingly, the other ends 14b, 14 of the coupling plates 14, 14 are connected.
b periodically and repeatedly moves along a locus drawn around the outer periphery of the eccentric inner ring 10. When the other end of the coupling plate 14 is repeatedly moved, the housing 9 vibrates around the outer periphery of the eccentric inner ring 10 and the displacement of the treatment elements 7a and 7b in the front-rear direction changes periodically, so that the massage by the beating operation is performed. I do. The housings 9, 9 are connected to the coupling plate 1 as described above.
Crankshaft portions 23 which are in axisymmetric relationship via 4 and 14
For example, when the treatment element 7a protrudes toward the human body side, the treatment element 7b is accommodated in the chair side, and the two treatment elements 7a and 7b alternately hit the human body. .

When a command to move the treatment elements 7a and 7b in the backward direction with respect to the human body is input to the control circuit 20 from the operation input circuit 21, the control circuit 20 causes the front and rear drive circuit 3c to rotate the front and rear drive source 3a. Then, a command is issued to rotate the front / rear drive shaft 3b clockwise when viewed from the front / rear drive source 3a. In this case, as shown in FIG. 7, the support plates 12a move toward the treatment elements 7a and 7b around the front and rear shafts 3b. Along with this, the other end 14b of the coupling plate 14 rotates counterclockwise as viewed from the front and rear drive source 3a along a locus drawn around the outer periphery of the eccentric inner ring 10, and the treatment elements 7a and 7b move backward in the human body. Move to. In addition, the operation element 7 is supplied from the operation input circuit 21.
When a command for moving the human body a, 7b in the forward direction with respect to the human body is input to the control circuit 20, the control circuit 20
c, a command is issued to rotate the front / rear drive source 3a in the reverse direction and to rotate the front / rear drive shaft 3b counterclockwise as viewed from the front / rear drive source 3a. As a result, the support plates 12a,... Move in the reverse direction, and the treatment elements 7a, 7b move forward of the human body. In addition, when the treatment elements 7a and 7b are moved in the forward direction, a massage in which the pressing force is increased can be performed.

When a command to move the treatment elements 7a and 7b upward with respect to the human body is input to the control circuit 20 from the operation input circuit 21, the control circuit 20 causes the vertical drive circuit 4c to rotate the vertical drive source 4a. A command is issued to rotate the vertical shaft 4b. As a result, the pinion 15 meshing with the rack 16 rotates, and 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 caused by rotating the vertical drive source 4a, the vertical shaft 4b and the pinion 15 in the opposite direction, lowering the frame 1, and moving the treatment elements 7a and 7b.
The downward movement of the human body b is performed.

When a command to reduce the distance between the treatment elements 7a and 7b is input from the operation input circuit 21 to the control circuit 20, the control circuit 20 causes the width drive circuit 5c to rotate the width drive source 5a and drive the width drive shaft. An instruction is given to rotate 5b. As a result, the pair of side plates 11 and 11 screwed to the width drive 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 approaching each other along the kneading shaft 2b. This movement reduces the distance between the treatment elements 7a and 7b. The expansion of the distance between the treatment elements 7a and 7b is achieved by rotating the width driving source 5a and the width shaft 5b in the opposite directions so that the housing 9 and the like move away from each other along the kneading shaft 2b. The distance between the treatment elements 7a and 7b increases.

In the above description of the operation, each operation has been described individually. However, a plurality of treatment elements 7a, 7
The operation command b may be input at the same time. In this case, the positions of the treatment elements 7a and 7b in the front-back, up-down, and width directions can be changed while massaging. In this embodiment, the front and rear drive source 3a, the vertical drive source 4a, and the width drive source 5a are provided, but at least one may be provided. In addition, although a rotary motor was used as a drive source,
A linear motor or the like may be used.
