Next, the operation will be described. In FIG. 2, when power is supplied from a power supply (not shown) to the width changing motor 12, the pulley 1 connected to the rotating shaft of the motor is rotated.
0 rotates, and the pulley 9 rotates through the belt 11 stretched on the pulley 10. When the pulley 9 rotates, the trapezoidal screw 6 rotates, and the two nuts 5 meshing with the trapezoidal screw 6 move. When the trapezoidal screw 6 rotates forward, the two nuts 5 move in the approaching direction, and when the trapezoidal screw 6 rotates in the reverse direction, the nuts 5 move in the direction moving away. That is, the arm support moving plate 3 fixed to the nut 5, the acupressure arm 2 supported by the arm support moving plate 3, and the acupressure roller 1 are integrated.
It is moved by the rotation of the trapezoidal screw 6. That is, as shown in FIG. 6, by controlling the rotation of the width changing motor 12, the position of the acupressure roller 1 with respect to the shoulder 38, which is the affected part of the massage, is adjusted.

After the acupressure roller 1 is arranged at a predetermined position of the affected area of the massage, the air pump 40 is operated as shown in FIG.
0 swells. As the airbag 30 inflates and the internal pressure increases, the acupressure arm 2 tilts toward the acupressure roller 1, and the acupressure roller 1 acupressures the affected area of the shoulder 38. After performing the acupressure for a predetermined time, the exhaust valve is opened to exhaust the air inside the airbag 30 to release the pressure, and the acupressure is stopped. The inflow and outflow of air into and from the airbag 30 is referred to as acupressure operation. Moving the acupressure roller 1 back and forth along the affected area while applying acupressure results in rolling massage.

In this acupressure operation, acupressure is sequentially performed at a plurality of acupressure points indicated by X in FIG. 6 while rotating the width changing motor 12 to adjust the position. At this time, the rotation of the width changing motor 12 causes the acupressure arm 2 to approach the neck 37, and further comes into contact with the neck 37, as shown in FIG.
The sensor frame 31 rotates against the load of the arm support spring 34 due to the contact pressure to the sensor frame 31. When the sensor frame 31 rotates, the neck detection sensor 35 is turned on and turned on.
Is transmitted to the control unit 50. Subsequently, the control unit 50 that has detected the ON output of the neck detection sensor 35 immediately reverses the rotation of the width changing motor 12 in FIG. 6 and moves the acupressure arm 2 to a position where the ON output of the neck detection sensor 35 is not detected. To move. This position is a position at which the pressure of the arm with respect to the neck becomes a predetermined value, that is, a position at which the predetermined pressure from the side of the user's neck side of the arm is detected.
In addition, depending on the load setting of the arm support spring 34, the neck 3
The predetermined pressure for detecting the contact with the neck 7 can be set freely, and usually, the pressure should be such that no pain is felt even when the acupressure arm 2 contacts the neck 37. Alternatively, the position may be moved to a position wider by a predetermined distance than the position where the neck detection sensor 35 detects the neck, and this position may be set as the inner limit position.

On the other hand, regarding the outer limit of the shoulder, when the width changing motor 12 is rotating in the reverse direction, the wide detection sensor 28
Is turned on, the control unit 50 detects this, and immediately rotates or stops the rotation of the width moving motor 12 so as to adjust the rotation so as not to exceed the limit point of the mechanism.

Further, in FIG.
When power is supplied from a power source (not shown) to the
The worm gear 20 connected to the rotation shaft 8 rotates, and the wheel gear 21 meshing with the worm gear 20 rotates. When the wheel gear 21 rotates, a pinion gear 23 coaxially connected to the wheel gear 21 rotates.
The teeth of the pinion gear 23 mesh with the teeth of the rack 24, and the rack 24 is fixed to the frame 17 in FIG. 2, so that the pinion gear 23 moves on the tooth surface of the rack 24. That is, the front and rear moving frame 14 and the acupressure arm 2 on which the wheel gear 21 is supported move back and forth.

The pinion gear 23 and the moving frame 14 move forward (toward the acupressure roller 1) when the motor 18 for forward and backward rotation rotates forward, and move backward when rotating in the reverse direction. When the forward / backward movement motor 18 rotates, the encoder light shielding plate 27 directly connected to the rotation shaft of the motor rotates. The rotation of the encoder light-shielding plate 27 is detected by the encoder photosensor 25, and the rotation speed of the front-rear movement motor 18 is controlled by the control unit 50.
Communicate to The forward / backward moving frame 14, that is, the acupressure arm 2, is output by the output of the encoder photosensor 25.
You can know the position of.

Similarly to the case where the width changing motor 12 is controlled based on the output of the neck detection sensor 35,
8 is rotating forward, the neck detection sensor 35 is turned on by contact with the neck 37 shown in FIG.
0 is transmitted. Subsequently, the control unit 50 that has detected the output of the neck detection sensor 35 immediately reverses the rotation of the front-rear movement motor 18 in FIG. 6 and moves the front-rear movement frame 14 to a position where the output of the neck detection sensor 35 is not detected. . Alternatively, the position may be moved to a position that is farther from the position where the neck detection sensor 35 detects the neck by a predetermined distance, and this position may be set as the limit position in the front-rear direction.

As described above, the acupressure arm 1 comes into contact with the neck 37, the sensor frame 31 rotates, and the neck detection sensor 35
Is turned on, and when the control unit 50 detects this ON output, the rotation direction of the width changing motor 12 and the forward / backward movement motor 18 is immediately reversed, and a position where the output of the neck detection sensor 35 is not detected or a preset position is set. Since the motors are reversely rotated to the positions separated by the distance, it is possible to prevent the acupressure arm 2 from being strongly pressed against the neck 37, and to prevent the neck from being damaged or giving discomfort. Therefore, a sense of security that the massage device can be used safely and comfortably can be given to the user.

Embodiment 2 Similarly to the massage device according to the first embodiment, FIGS. 1 to 7 show the massage device according to the second embodiment, and all the components 1 to 50 are configured by the same components as those in the first embodiment. FIG. 8 is an explanatory view of Embodiment 2 of the present invention. In FIG. 8, a distance detection sensor 60 fixed to one arm support moving plate 3, a light emitting portion 61 of the distance detection sensor 60, a distance detection sensor Light receiving part 6
2 is provided. The output value of the amount of incident light received by the light receiving unit 62 of the distance detection sensor 60 is monitored by the control unit 50.

Next, the operation will be described. 8, the light emitted from the light emitting unit 61 of the distance detection sensor 60 reaches the arm support moving plate 3 on the facing side, is reflected, and returns toward the distance detection sensor 60. When the reflected and returned light is incident on the light receiving unit 62 of the distance detection sensor 60 and received, the output value corresponding to the amount of the incident and received light is transmitted to the control unit 50. The amount of reflected light depends on the position of the arm support moving plate 3 on the facing side, and when it is at a far position, the reflected light is diffused and the amount of light incident on the light receiving unit decreases. In addition, when the light is close, the reflected light has less diffusion and the amount of incident light on the light receiving unit increases.

The position of the arm support moving plate 3 can be known from the difference in the amount of reflected light incident on the light receiving unit 62, and the output value of the amount of incident light is transmitted to the control unit 50. That is, a large output value is transmitted to the control unit 50 when the interval between the two arm support moving plates 3 is small, and a small output value is transmitted to the control unit 50 when the interval is large.

In the massage device provided with the distance detection sensor 60, the finger pressure is sequentially performed at the X pressure point shown in FIG. 6 while adjusting the position by rotating the width changing motor 12. At this time, the rotation of the motor for changing the width causes the acupressure arm 2 to approach the neck 37, and when the acupressure arm 2 comes into contact with the neck 37, the sensor is pressed against the load of the arm support spring 34 by the contact pressure on the neck 37 as shown in FIG. Frame 31
Rotates. When the sensor frame 31 rotates, the neck detection sensor 35 is turned ON, and the ON output is transmitted to the control unit 50. Subsequently, the control unit 50 that has detected the output of the neck detection sensor 35 immediately reverses the rotation of the width changing motor 12 shown in FIG. 6 to a position where the output of the neck detection sensor 35 is not detected or a position that is wide by a preset distance. The position of the acupressure arm 2 is moved to.

The output value of the distance detection sensor at the position in this state due to the light incident on the light receiving unit 62 is stored in the control unit 50 (that is, the positions of the acupressure arm 2 and the arm support moving plate 3 are stored). Every time, when the output value becomes equal to or larger than the output value stored when the width changing motor 12 is rotated forward again, the width changing motor 12 is immediately rotated reversely.

By storing the output value of the encoder photosensor 25 in the control unit 50 to store the front-back position of the acupressure arm 2 and storing the output of the neck detection sensor 35 in association with each other, FIG. The two-dimensional map of the neck as shown is stored in the control unit 50. Based on this two-dimensional map, the acupressure operation is performed while adjusting the position so as to avoid the neck 37 and also go behind the neck 37.

As described above, the limit position is stored by the distance detection sensor 60 for detecting the distance between the arm support moving plate 3 and the acupressure arm 2 and the output value of the light receiving section 62 of the distance detection sensor 60. The width changing motor 12 is controlled so as not to approach the neck side beyond the limit position, so that once it touches the neck 37, it can be prevented from touching the neck 37 again. Therefore, uncomfortable contact of the acupressure arm 2 with the neck 37 can be minimized.

Also, since the position of the acupressure arm 2 and the limit position at which the neck detection sensor 35 does not output are stored in association with each other, the acupressure is automatically performed over a wide area over the entire shoulder, avoiding the neck 37. Can do things.

It is also conceivable to use a distance detection sensor 60 on the neck side surface of the acupressure arm 2 instead of the sensor frame 31 and the neck detection sensor 35. In this case, there is an advantage that the position can be known without bringing the acupressure arm 2 into contact with the neck.

[0052]

As described above, according to the massage machine of the present invention, the contact of the arm with the neck is detected and the arm is separated, so that the interval between the arms is too narrow and the neck is pressed, so that the breathing is difficult. You can avoid the problem and massage your neck with a sense of security.

According to the massage machine of the present invention,
The arm is moved to a position that does not detect the ON output of the neck detection sensor or to a position that is a preset distance away by detecting the contact pressure on the neck, so that the neck may be damaged by large pressure or discomfort You can avoid giving and massage your neck with a sense of security.

According to the massage machine of the present invention,
Since the contact limit position with the neck is stored, even when the same place is repeatedly subjected to acupressure, the arm can be prevented from coming into contact with the neck, and the neck can be massaged with a sense of security.

According to the massage machine of the present invention,
Based on memorizing the position coordinates of the neck, avoiding the neck, moving the arm position and changing the position while automatically performing shiatsu operation over a wide range of shoulders including the back side of the neck,
The massage can be done over a wide area, without hassle and without any pain.
