2. Description of the Related Art Conventionally, a chair-type massage machine for giving a massage to the back in a sitting posture has been widely used. According to such a chair-type massage machine, a massage can be received in a relatively comfortable posture.

[0003]

However, in a chair-type massage machine, the massage unit only performs a rubbing operation, so in order to receive an effective massage, the back should be pressed to the massage unit side with an appropriate force. It needs to be pressed. Therefore, the human body is slightly tense. On the other hand, a massage by a professional masseuse can be received in a relaxed state, lying prone.

Therefore, the massage by the chair-type massage machine has a problem that a high massage effect cannot be obtained because the operation and the feeling to be received are largely different from the massage by the masseur. However, long-term use may rather cause fatigue. An object of the present invention is to provide a massage machine that can obtain a high massage effect without being tired even when used for a long time.

It is supplied to the control circuit (5) (not shown). Also handle
When a lateral operating force is applied to (41), a control signal according to the operating force is supplied to a control circuit (not shown) of the lateral moving mechanism. Further, when the force for gripping the handle (41) is changed, a signal corresponding to the grip force is supplied to the finger pressure adjusting mechanism.

FIG. 3 shows an example of the structure of the forward-backward moving mechanism (5). The right slide member (12) is slidably engaged with the guide rail (53) of the forward-backward moving mechanism (5) to move forward and backward. Is guided, and the motor (51) is engaged with the connected ball screw (52) to be driven back and forth. The front-rear moving mechanism (5) for the left slide member (11) has the same structure.

The lock mechanism (13) shown in FIG. 3 locks the massage unit support arch (2) by sandwiching the tip of the massage unit support arch (2) from both sides.

FIG. 4 shows an example of the structure of the horizontal movement mechanism (6). A guide rail (67) curved in an arc shape is attached to the massage unit support arch (2), and two sliding members (65) (for each massage unit (3) are attached to the guide rail (67). 65) is slidably fitted, and these two sliding members (65) (65) form one massage unit (3).
Is supported.

The massage unit support arch (2) includes:
A motor (61) serving as a drive source of the left-right movement mechanism (6) is attached. A pair of left and right spiral springs (63) and (63) are provided on both sides of the motor (61).
A wire (62) is stretched between 3). The wire (6
In 2), the base end is connected to the spiral springs (63) and (63), and is wound around the peripheral surface of the pulley (64) a plurality of times as shown in FIG. ) Is wrapped around the output shaft (60). The wire (62) is located between the pulley (64) and the spiral spring (63) as shown in FIG.
It is fixed to an arm (66) protruding from (3).

Therefore, when the motor (61) rotates forward and backward,
The rotation is transmitted to the pulley (64) through the wire (62), and the wire (62) wound around the pulley (64) is wound or unwound, whereby the pulley (64) and the spiral spring (63) are separated from each other. The wire 62 moves left and right, and the massage units 3 and 3 are driven left and right accordingly.

FIG. 6 shows an example of the structure of the massage unit (3). The massage unit (3) has a motor
A cam (31), which is rotationally driven in the reverse direction by (32), is built in, and a finger-pressure rod (34), which is reciprocally driven by the rotation of the cam (31), projects its tip from the massage unit (3). Have been deployed. The acupressure rod (34) is biased toward the cam (31) by a reaction force spring (33) attached to the base end portion. Therefore, the acupressure rod (34) is always in sliding contact with the peripheral surface of the cam (31) and reciprocates according to the change of the cam curve accompanying the rotation of the cam (31).

Further, the massage unit (3) is attached to the massage unit supporting arch (2) through a plurality of buffer springs (35), and excessive finger pressure acts on the human body by the finger pressure rod (34). Is being prevented.

As shown in FIG. 7, the handle of the controller (4)
A pressure sensor (42) is attached to each of the gripping portions of both hands of the (41), and a change in the grip force of the user is detected by this. For the pressure-sensitive sensor (42), various well-known structures such as a structure using a pressure-sensitive conductive rubber and a structure utilizing a repulsive force of a spring can be adopted.

As shown in FIG. 8, the grip force detection signal S from the pressure sensor (42) is supplied to the arithmetic processing circuit (71) and the motor driver.
It is supplied to the control circuit (7) composed of (72). Arithmetic processing circuit
At (71), first, the rotation angle of the cam (31) is calculated according to the magnitude of the gripping force detection signal S. FIG. 9A shows an example of the relationship between the grip force F and the cam rotation angle, which gives a cam rotation angle proportional to the grip force, that is, the magnitude of the grip force detection signal S.

The arithmetic processing circuit (71) further converts the rotation angle of the cam (31) into the rotation amount of the motor (32) and gives a drive pulse corresponding to the rotation amount to the motor driver (72). As a result, the cam (31) rotates and finger pressure is generated by the finger pressure bar (34) as described above. FIG. 9B shows the relationship between the cam rotation angle and the finger pressure. The cam rotation angle is from 0 degree to 180 degrees.
In the range up to degrees, as the cam rotation angle increases,
Finger pressure increases. Therefore, 0 to 180 degrees is used for adjusting finger pressure.

FIG. 9C shows how the finger pressure is adjusted by changing the grip force F. Grip strength F
If is kept constant, the finger pressure is also kept constant, and the user can arbitrarily adjust the finger pressure by adjusting the grip force.

As described above, according to the massage machine of the present invention, the back can be massaged in the state of lying prone on the base (1), that is, in the most relaxed posture, and the massage can be performed by a professional masseur. The same massage effect as is obtained. In addition, it is possible to reduce the size and save the storage space as compared with the conventional chair-type massage machine.

The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the claims or limiting the scope. Further, the configuration of each part of the present invention is not limited to the above embodiment, but various modifications can be made within the technical scope described in the claims.

For example, in the structure of the massage unit (3), a clutch is provided in the power transmission path between the motor (32) and the cam (31), and the finger pressure by the finger pressure rod (34) is detected. When the finger pressure exceeds a predetermined limit value, the clutch can be disengaged for safety.
As the massage unit (3), it goes without saying that not only the acupressure mechanism as in the above embodiment, but also various known massage mechanisms such as a vibration adding mechanism can be adopted.
