The fixation of the rotational movement angle of the treatment arm 12 hinges one end of the rock block link 41 to the treatment arm 12 and allows the other end to be detachably locked to the rocking arm 21. The treatment arm 12, which is rotated in accordance with the lifting and lowering of the massage unit 2 by the automatic rotation movement mechanism 6, is prevented by unnecessary rotation movement during the massage by the rotation movement rock mechanism 4.

FIG. 8 is a perspective view of the rotary rock mechanism 4, FIG. 9 is a front view of the rotary rock mechanism, FIG. 10 is a right side view of FIG. 9, and a pulley 25 (inside the rocking arm 21) ( 26) is shown broken. The rotary motion mechanism 4 is installed so as to be slidable about the base 40 and the base 40 on which the rotational movement is freely installed on the rocking arm 21, and the tip is coaxial with the lower treatment finger 11. A rock lock link 41 connected to the arm 12 and a movable plate 42 provided to be liftable with respect to the rock lock link 41 are provided. The base 40 and the movable plate 42 are covered by the case 19 and the subject does not come into direct contact.

As shown in FIG. 10, the guide tube 70 penetrates through the rocking arm 21 and the pulleys 25 and 26, and the amvil 72 is freely fitted to the guide cylinder 70. The avil 72 is applied to the outward in the guide cylinder 70 by the spring 44, the base 40 is freely rotated around the guide cylinder 70. At the end of the pulley 26 side, the unlocking wire 71 to be described later extends.

An opening 45 extending in the longitudinal direction is formed at the base end of the rock lock link 41 opposite to the rocking arm 21, and the avil 72 penetrates the opening 45 so that the tip end is rock-locked. It is supported by the guide plate 46 provided outside the link 41. The guide plate 46 is fixed to the substrate 40 through the opening 45.

In the movable plate 42, two longitudinal holes 47 and 47 are installed in parallel, and the longitudinal holes 47 and 47 are fitted with protrusions 48 and 48 extending outward from the rock lock link 41. . A spring plate 49 is installed on the movable plate 42 so as to be able to swing, and both ends of the spring plate 49 push upwards of the protrusion shafts 48 and 48 so that the protrusion shafts 48 and 48 are vertical holes 47 ( It is pressed against the upper edge of 47). At the lower end of the movable plate 42, the triangular protrusion pieces 43 and 43 protrude downward, and the tip end portion of the amvil 72 is located between the positive protrusion pieces 43 and 43. The upper end of the ambiville 72 is sharp and contacts the upper end of the ambiville 72 and the one-sided piece 43 of the movable plate 42 in accordance with the slide of the armlock link 41 and the movable plate 42. The detection switch SW1 (SW2) is provided in the bidirectional end of the movement path of the movable plate 42 on the base 40. As shown in FIG.

As shown in FIG. 9, since the ambulance 72 is positioned between the stone pieces 43 and 43, the treatment arm 12 is rotated upward to lower the treatment finger as shown in FIG. 7B. (11) abut this waist. The operation of the rotary motion mechanism (4) will be described.

The dark rock link 41 is pulled to the left by the rotational movement of the treatment arm 12.

The projections 48 and 48 of the female rock link 41 press the movable plate 42 to the left. The stone piece 43 on the right side of the movable plate 42 abuts against the tip of the avil 72, and the movable plate 42 is opposed to the spring plate 49 as shown in Fig. 11 (a). It rotates counterclockwise by the margin of the fulcrum 48. Then, when the rock link 41 and the movable plate 42 slide, the movable plate 42 is pushed downward by the spring plate 49 after the protrusion 43 of the movable plate 42 passes over the ambly 72. As shown in FIG. 11 (b), the right side stone piece 43 of the movable plate 42 is located on the left side of the amvil 72. Since the movable plate 42 is pushed downward by the spring plate 49, the arm lock link 41 regulates unnecessary swing to the right during the kneading operation so that the lower treatment finger 11 can rotate in the direction falling from the waist. There is no concern.

In addition, in the state shown in FIG. 11 (b), when the force is applied to the right side with the strong force of the rock lock link 41, the rock piece 43 of the movable plate 42 crosses the ambil 72 and the rock lock link 41 is moved. There is a risk of doing a bending exercise to the right. However, as shown in Fig. 14 (a), when the inner side of the protrusions 43 and 43 is the inclined surface 72a, even if the arm lock link 41 is strongly applied to the right side, as shown in Fig. 14 (b), The vertical surface 43b of 43 is in contact with the avil 72, and the locking effect of the dark lock link 41 can be enhanced.

The dark green link 41 presses the detection switch SW1, and a signal from the detection switch SW1 is transmitted to the patient, thereby confirming that the treatment arm 12 is locked.

In addition, since the tip of the amville 72 is located between the stone pieces 43 and 43, when the treatment arm 12 is rotated downward, the movable plate 42 springs as shown in FIG. 11 (c). It rotates clockwise against the plate 49 and the left hand piece 43 passes over the amville 72. As shown in Fig. 11 (d), the rock-block link 41 is controlled to be bent to the left and there is no fear that the upper treatment finger 10 rotates in a direction falling from the shoulder. Also in this case, if the shapes of the protrusion pieces 43 and 43 and the ambly 72 of the movable plate 42 are formed as shown in FIG.14 (c), the locking effect of the dark lock link 41 can be improved.

(Unlock)

The lock is released to allow the treatment arm 12 to freely rotate again. This unlocking mechanism 7 is shown below.

As shown in FIG. 10, an unlocking wire 71 is installed at an end of the avil 72 that is in contact with the pulley 26. When the unlocking wire 71 is tensioned against the spring 44, the ambly 72 is extended. Drawn in. The abutment 72 and the movable plate 42 are abutted so that the armlock link 41 and the movable plate 42 can be folded and the treatment arm 12 is free to rotate.

The moving pulley 75 and the slide body 8 are weakly applied downward by the tension spring 83 hung between the base 20 and the moving pulley 75.

The lock release wire 71 extending from one rocking arm 12 is wound around the relay pulley 74 and the moving pulley 75 and connected to the other rocking arm 21.

When the treatment arm 12 is locked to perform the kneading motion, the pair of rocking arms 21 and 21 shown in FIG. 2 are approached and separated from each other, so that the unlocking wire 71 contracts or relaxes to change tension. Since the moving pulley 75 is lightly applied, the moving pulley 75 moves up and down by the tension change of the unlocking wire 71.

In order to release the lock of the treatment arm 12, the solenoid 81 is energized to protrude the pin 82. The pin 82 is fitted to the recessed portion 80 of the slide body 8 through the opening 76. The slide body 8 is restricted in shanghai copper and the tension of the unlocking wire 71 is high. The avil 72 shown in FIG. 10 is pulled out and the abutment with the movable plate 42 is released. In this way, the lock of the treatment cancer 12 is released. That is, the solenoid 81 is operated during the kneading operation to release the lock of the treatment arm 12. As a result, both the treatment fingers 10 and 11 are equally in contact with each other when the middle part and the like are massaged and the massage effect is high.

As described above, the present invention obtains the effect of increasing the massage effect by enabling the control and release of the free rotational movement of the treatment arm to the site of massage.
