Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. The illustrated massage machine is incorporated in the back of a chair or in a bed. In the illustrated example, as shown in FIG. 4, the chair can be reclined freely. Show what is built into the backrest. In this chair, a seat 82 and an armrest 83 are provided on a lower frame 81 framed by a pipe, and a lower portion of a frame 85 of a backrest 84 is pivotally connected to the lower frame 81, and a gas spring is provided between the lower end of the frame 85 and the lower frame 81. The backrest 84 can be reclined by the expansion and contraction of the gas spring 86 by the operation of a lever 87 provided on the side of the armrest 83, and the frame 85 on both sides of the backrest 84 has a U-shaped cross section. The pair of rails 90 facing each other are fixed. A headrest 88 is provided at the upper end of the backrest 84, and support bands 89 are provided vertically on both sides of the back surface of the cover sheet provided up to the headrest 88 on the front surface of the backrest 84. Racks 91, 91 are fixed to the opening edges of the pair of rails 90, 90 along the longitudinal direction, respectively. A massage machine having a meshing pinion 17 is installed.

The massage machine has a motor block 20 at one end and a speed reducer block 19 at the other end as shown at 34, and the rollers 18 and the pinion 17 that is driven to rotate are protruded from both blocks 20, 19. The main shaft 1, the screw shaft 14 and the auxiliary shaft 13 are provided between the blocks 20 and 19. The auxiliary shaft 13 whose both ends are supported by both blocks 20 and 19 is connected to the main shaft 1, the screw shaft 14, and the rotary shaft 15 via a pair of rotating plates 15 and 15 rotatable with respect to the auxiliary shaft 13. A rotating shaft 12 parallel to the auxiliary shaft 13 is attached so that the rotating shaft 12 can rotate around the auxiliary shaft 13. The rotating shaft 12 whose both ends are supported by the pair of rotating plates 15, 15 is rotatable with respect to the rotating plate 15. The rotating shaft 12 is formed by connecting a pair of crankshafts 12a and 12b whose eccentric directions are opposite to each other in the axial direction, and non-eccentric portions at both ends are supported by the rotating plate 15.

The main motor housed in the motor block 20 drives each of the main shaft 1, the rotary shaft 12, and the pinion 17, and also drives the rotary shaft 12 around the auxiliary shaft 13. That is, a driven shaft 31 disposed on the outer surface of the speed reducer block 19 is connected to the pulley 28 mounted on the output shaft of the motor projecting below the motor block 20 via the belt 29 and the pulley 30. The driven shaft 31 and the speed reduction mechanism in the speed reducer block 19 are connected by a clutch 33, pulleys 34 and 36, and a belt 35. A speed reduction mechanism (not shown) in the speed reducer block 19 includes a speed reduction unit and a plurality of clutches. When the clutch 33 is connected, a motor output is transmitted to the main shaft 1 or the pinion 17. Communicate selectively. A worm wheel 41 mounted on the auxiliary shaft 13 is connected to the driven shaft 31 via a clutch 32, a pulley 37, a belt 38, a pulley 39, and a worm 40, and a pulley 42 integrated with the worm wheel 41. Are connected to a pulley 43 fixed to the rotating shaft 12 by a belt 44. When the clutch 32 is connected, the motor output is transmitted to the rotating shaft 12 by each of the above members, and the rotating shaft 12 rotates around the shaft.

Further, on the outer surface of the motor block 20, a high / low motor 24 is provided, and a feed screw 25 driven by the high / low motor 24 is provided. A feed nut 26 screwed to the feed screw 25, One of the pair of rotating plates 15, 15 is connected by an extendable pressure sensor block 16. When the feed screw 25 rotates at the output of the motor 24, the feed nut 26 moving in the axial direction of the feed screw 25 moves the rotary plate 15 via the pressure sensor block 16, and as a result, the rotary plate 15 The rotary shaft 12 supported by the rotary shaft 13 rotates around the auxiliary shaft 13.

幅 The width motor 23 arranged on the outer surface of the speed reducer block 19 rotates the screw shaft 14 because the worm 22 attached to the output shaft is engaged with the worm wheel mounted on the screw shaft 14. Now, a pair of inner rings 2 and 2 are attached to the main shaft 1 at intervals. The two inner rings 2 and 2 are eccentric in the same direction with respect to the main shaft 1 by the same amount and are inclined in opposite directions, and rotate with the main shaft 1 by engagement with the ridges 11 formed on the main shaft 1. So that the outer ring 3 is freely slidable in the axial direction of the main shaft 1. One end of each of the connecting arms 6 and 6 is freely rotatably connected to the outer peripheral surface of the non-eccentric portion of each of the inner rings 2 and 2. The connecting arm 6 that slides in the axial direction of the main shaft 1 together with the inner ring 2 is screwed with the screw shaft 14, and the screw direction of the screw shaft 14 is reversed. A pair of connecting arms 6 and 6 screwed to the portions respectively move the pair of inner rings 2 and 2 closer to and away from each other as the screw shaft 14 rotates.

The middle portion of each of the arms 4 is fixed to each of the outer races 3, and a roller-shaped treatment element that is freely rotatable with respect to the arm 4 is provided at a bent portion at the tip of each arm 4. The other end of each arm 4 is connected to the rotating shaft 12 via a connecting link 8. As shown in FIG. 10, the two connecting links 8, 8 are a pair of molded halves 8a, 8b, a screw 8d for connecting the halves 8a, and a reinforcing member made of sheet metal which is put on the combined halves 8a, 8b. As shown in FIG. 5, as shown in FIG. Further, a connecting portion between the connecting link 8 and the arm 4 is also formed as a ball joint 70 so that the connecting link 8 and the arm 4 can be freely three-dimensionally rotated. The other connecting link 8 engages with a sphere 80 provided on the crankshaft 12b, which is also an eccentric part of the rotary shaft 12, and a sphere 80 provided on the crankshaft 12a which is an eccentric part of the rotary shaft 12. And . The non-eccentric portion at the center of the rotary shaft 12 and the auxiliary shaft 13 are connected to each other by a connecting plate 9 which is freely rotatable.

Reference numeral 16 in FIGS. 6 to 8 denotes a pressure sensor block, which is connected to the arm 4 via the connecting link 8 and the rotating shaft 12 and the rotating plate 15, and is used when the treatment element 5 presses the human body from the back. Since the reaction force acts as a pulling force via the arm 4 and the rotating plate 15, the pressure applied to the treatment element 5 is detected by detecting this force. Based on the pressure detected in this way, detection of the shape of the back of the human body, determination of the shoulder position, and the like, feedback control of the intensity of massage, and the like are performed, but this point is omitted here.

Next, the operation will be described. When the main shaft 1 is rotated by the main motor, the inner ring 2 that rotates together with the main shaft 1 is eccentric and inclined with respect to the main shaft 1. The treatment element 5 attached via the arm 4 to the arm 4 is restricted by the rotation of the main shaft 1 because the movement of the arm 4 is restricted by the connecting link 8, as shown in FIGS. A motion that draws a dimensional trajectory TR, that is, a motion that changes the position in the up-down direction, the axial direction of the main shaft 1, and the protruding direction from the main shaft 1 is performed. FIG. 7 shows the trajectory TR when the treatment element 5 is viewed from the front. The pair of treatment elements 5 and 5 that perform such a movement symmetrically give a so-called “sticky massage” massage to the back of the user. The connecting link 8 connected to the arm 4 via the ball joint 70 swings up, down, left and right with the rotation of the inner ring 2. The connecting link 8 and the rotating shaft 12 constitute a ball joint. The operation of the treatment element 5 is performed smoothly since the treatment elements 5 are connected via the sphere 80.

When the rotation shaft 12 is rotated around the auxiliary shaft 13 via the pressure sensor block 16 and the rotation plate 15 by rotating the feed screw 25 by the high / low motor 24, the arm 4 and the outer race 3 Is rotated around the inner ring 2 and the treatment element 5 changes the amount of projection in the front direction where the back of the user is located. And a weak fir massage can be selectively performed. It is possible to adjust the strength.

When the rotary shaft 12 is rotated around the main shaft 1 as shown in FIG. 8 instead of the main shaft 1, the connecting link 8 that is moved as the crankshafts 12a and 12b, which are eccentric portions of the rotary shaft 12, rotates, The arm 4 connected via the joint 70 is moved. At this time, the movement of the arm 4 turns around the stopped inner ring 2 together with the outer ring 3. Depending on the position of the inner ring 2, the child 5 is substantially linearly reciprocated in a vertical direction when viewed from the front, and performs tapping massage. Since the respective eccentric directions of the two crankshafts 12a and 12b of the rotary shaft 12 are opposite to each other, the tapping operation by the pair of treatment elements 5 and 5 is performed alternately.

(4) When the pinion 17 is rotated by the main motor, the massager moves the chair backrest 84 up and down along the rail 90 due to the engagement between the rack 91 and the pinion 17. Therefore, the position of the treatment element 5 can be changed up and down. At this time, a rolling massage in which the treatment element 5 moves while rubbing the back of the human body can be obtained. Further, when the screw shaft 14 is rotated by the width motor 23, the treatment element 5 moves in the axial direction of the main shaft 1 as shown by a chain line in FIG. The position of the treatment element 5 in the axial direction can be changed depending on whether the part to be treated is the shoulder or the neck.

In this massage machine, acupressure massage can be obtained by causing the treatment element 5 to perform the following movement. That is, the fir operation by the treatment element 5 is obtained by rotating the main motor at a constant speed or a variable speed in a fixed direction as shown in FIG. When a part of the massage massage operation is repeated by the treatment element 5 by repeating the operation, the acupressure operation can be obtained as shown in FIG. At this time, the rotation of the main motor may simply repeat forward rotation CW direction rotation and reverse rotation CCW direction rotation as shown in FIGS. 2 (b) and 2 (c), but as shown in FIG. If the main motor is stopped for a while when switching from the forward rotation CW to the reverse rotation CCW, and the state where the acupressure is the highest is maintained for a while, a more effective acupressure operation can be obtained. The maximum value of the acupressure is variable by adjusting the amount of protrusion.
