1 to 10, when the massage device 50 moves up and down inside the backrest of the massage chair 180, first, by operating a drive switch (not shown), the frame drive motor 33 When the excitation current flows, the drive gear 35 installed in the frame drive motor 33 is rotated to transmit rotational power in a state of being engaged with the electric gear 36 orthogonal thereto.

At this time, the frame drive shaft 28 connected to the electric gear 36 is rotated and at the same time the pinion (30, 31) installed on both ends of the rack gear is installed inside the guide rail (21) (22) ( 26) (27) to climb upwards or downwards.

That is, the pinion (30) and (31) is to perform a linear movement while riding the rack gear 26, 27 at the same time while rotating the frame, the frame drive shaft 28 that traverses the slide frame 24 in the horizontal direction The massage mechanism 50 and the control unit 40 installed on the slide frame 24 are moved up and down in the same direction as the direction in which the pinion 30 and 31 are moved by leading the slide frame 24. ), Limit switches LSW1, LSW2, and the like move in accordance with the movement direction of the slide frame 24.

At this time, the idle shaft 140, which is located below the slide frame 24, i.e., in parallel with the frame drive shaft 28, is distorted with the balance gears 145 and 146 installed at both ends thereof. It is prevented to act to help move smoothly on the guide rails (26, 27).

When the slide frame 24 reaches the upper or lower limit position, an upper limit switch LSW1 or a lower limit switch LSW2 provided on the slide frame 24 is provided at the upper and lower ends of the guide rails 26, respectively. When the upper switch dog 38a or the lower switch dog 38b installed is touched and the signal is input to the input interface circuit unit (not shown) of the controller 40 so that the upper limit switch LSW1 is touched. The slide frame 24 is lowered by rotating the frame drive motor 33 in the opposite direction to the direction in which it was rotated. When the lower limit switch LSW2 is touched, the frame drive motor 33 is rotated in the direction of rotation. By rotating in the opposite direction with respect to the slide frame 24 to rise it can be repeatedly reciprocating in the vertical direction.

Meanwhile, the massage arms 56 and 57 and the massage balls 62 and 63 installed on the massage device 50 installed on the slide frame 24 may be moved in the left and right width directions or the up and down alternate directions. First, the massage arms 56 and 57 are moved in the left and right width directions to adjust the widths of the massage balls 62 and 63 installed at the ends thereof according to the size of the subject (for example, the width of the spine). Same as

First, when the switch is operated to drive the arm drive motor 51 in the forward direction, the forward excitation current flows from the motor drive unit (not shown) to the arm drive motor 51 by the drive signal of the controller 40.

At this time, by the one-way rotational action of the first one-way clutch bearing 53 interposed between the drive shaft 52 and the small pulley 82a, the small pulley 82a is rotated in the same direction with the driving shaft 52 and decelerated. Rotational power is transmitted to the camshaft 54 through the means 80, and the camshaft 54 rotates the deflection shafts 54a and 54b provided at both ends thereof so that one massage arm 56 and 57 The width of the massage balls 62 and 63 is adjusted while angular movement is performed at a double angle of the predetermined angle θ °.

In other words, the arm drive motor 51 → drive pulley 71 → belt 73 → electric pulley 72 → drive shaft 52 → first one-way clutch bearing 53 → small pulley 82a → belt 87a. → pulley (83b) → small pulley (83a) → belt (87b) → large pulley (84b) → small pulley (84a) → belt (87c) → large pulley (82b) → camshaft 54 → deflection shaft ( 54a) (54b) → Massage arms (56) (57) → Massage balls (62) (63) through the power transmission system and finally the massage balls (62) (63) are moved closer or closer to each other in left and right directions. Will reciprocate.

Since the deflection shafts 54a and 54b are formed to form a predetermined angle (θ °) with the rotational center of the camshaft 54 from above, the massage arms 56 and 57 rotatably installed thereon are provided at a predetermined angle (θ °). The oscillating motion will be as much as 2 times of the angle.

On the other hand, the second driven pulley 94 is driven by the one-way rotational action of the second one-way clutch bearing 58 interposed between the drive shaft 52 and the second driven pulley 94. It is stationary without receiving power. Furthermore, the rotational resistance means 100 for pressing the small pulley 82a and the eccentric drive shaft 59 is prevented from being rotated along with the drive shaft by the viscous resistance or slight frictional force of the second one-way clutch bearing 58. .

In addition, the massage arms 56, 57 and massage balls 62, 63 provided on the massage device 50 provided on the slide frame 24 are moved in the up and down alternating directions, and the massage balls 62 are installed at the ends thereof. 63) to describe the case of tapping or squeezing the human body of the subject as follows.

First, when the switch is operated to drive the arm drive motor 51 in the reverse direction, the reverse excitation current flows from the motor drive unit (not shown) to the arm drive motor 51 by the drive signal of the control unit 40.

At this time, the arm drive motor 51 is rotated in the direction of the arrow L indicated by the dotted line in the figure, and at the same time the drive pulley 71, the belt 73, and the electric pulley constituting the motive power transmission means 70. 72) are all rotated in the same direction at the same time.

At this time, by the one-way rotational action of the first one-way clutch bearing 53 interposed between the drive shaft 52 and the small pulley 82a, the small pulley 82a is idle and driven by the small pulley 82a. The second electric pulley 94 is rotated in the same direction with the drive shaft 52 by the one-way rotational action of the second one-way clutch bearing 58 on the other hand. The first driven pulley 92 is rotated through 96b).

At this time, the first driven pulley 92 rotates the eccentric drive shaft 59 in the same direction to make the up and down rocking motion of the crank arms 60 and 61 connected to the eccentric shafts 59a and 59b on both sides thereof. Given.

During the above process, the eccentric drive shaft (8) through the step pulley (84) and the other bearing (85) which are installed on the drive shaft (52) through the large pulley (82b) and the bearing (86) installed on the camshaft (54). The step pulley 83, which is installed on the 59 so as to be idling, has a small pulley 82a in a state of being stopped by the first one-way clutch bearing 53 and the rotational resistance means 100 and a belt connecting them ( The stopped state is maintained by 87a) 87b and 87c.

At this time, the screw 131, 134 and the nuts 141, 144 located at both ends of the pad insertion portion 110, 111, 112, 113 in the rotation resistance means 100 to tighten or loosen to operate. When the friction pad 104 and the friction cylinder 102 and another friction pad 106 and the annular groove 59g is changed, the sensitivity can be adjusted.

That is, when the first one-way clutch bearing 53 is in a state capable of transmitting power, the second one-way clutch bearing 58 is in a state in which power cannot be transmitted, and conversely, the first one-way clutch bearing ( When 53 is in a state in which power cannot be transmitted, the second one-way clutch bearing 58 is in a state in which power can be transmitted, so that the massage ball 62 (using the rotation direction of the arm drive motor 51) is one. It is possible to supply the power necessary for two operations of adjusting or tapping the width of 63).

The present invention as described above is configured to be able to arbitrarily vary the width of the massage ball to fit the physique of the subject, since it can stimulate the acupoints of the human body more accurately, the effect of improving the acupressure and massage effect is Of course, unlike when equipped with a drive motor corresponding to each function as in the past, a single drive motor is configured to supply the power required for tapping motion or the width adjustment between the massage ball, so that the drive motor There is an effect that can reduce the cost by reducing the number.
