Japanese Patent No. 361885

Although the massage machine according to the background art is configured as described above and can rehabilitate the knee for the victim, the knee can bend and stretched even if the footrest is rotated similarly for a healthy person. There is a problem that it is not possible to obtain a sufficient treatment effect simply by making them.
In addition, the massage machine of the background art has a flat leg mounting table and cannot stably support the foot, and when the footrest is opened alternately, the foot contact surface of one footrest There is also a problem that the foot is caught by the back surface of the other footrest.

  In order to solve the above-described problems, an object of the present invention is to provide a new treatment for the rotation of the footrest, not just the bending and stretching action of the knee.

(1) A massage machine according to the present invention includes a backrest portion, a seat portion, a footrest that is pivotally attached to the vicinity of the front end of the seat portion so as to be separately pivotable to the left and right, and a footrest that rotates the footrest. And a control unit that controls the drive unit to move the footrest up and down alternately, and is housed in the backrest unit, and can be protruded separately to the left and right in the back direction of the user. It arranged right and left pair of massaging balls for performing, when the control unit is increased left footrest or the right footrest, after is projected to the right of the kneading balls is the rise in the left footrest, projected state controlled to be lowered in the backrest subordinate direction to maintain, after allowed to protrude massaging balls on the left with the rise of the right footrest, be controlled so as to descend to the backrest subordinate direction to maintain the projecting state It is intended. Thus, in the present invention, the backrest, the seat, and the footrest that can be rotated independently on the left and right sides are provided, and when the one footrest is raised by the control unit, the side on the opposite side to the side on which the footrest is disposed. Since the ball protrudes, the leg can be firmly stretched by raising one of the footrests, and the raised leg and the upper body on the opposite side can be pushed out and twisted by the kneading balls. The body of the user can be bent diagonally, and new treatment can be provided to the user. Further, the kneading balls particularly support the back of the user, and even if the kneading balls swing in this state, the user can obtain a higher treatment effect. Furthermore, the movement of the user is not moved symmetrically, but is operated so as not to be symmetrical on one side and the other side, so that the balance of the user is lost and the balance is stabilized. The user himself / herself moves to realize a passive movement. Further, when the upper half of the user is twisted by projecting one of the left and right side balls as described above, the position of the ball is not only projected and returned, but the position of the ball is maintained even if the protruding state is maintained. Since it is lowered, the person bends his back around the waist in the sitting position, so even if the same amount of protrusion of the kneading balls, the kneading also descends in the waist direction, which is the center of rotation, so that the patient can be seen more The ball can be pushed out, that is, the user can be twisted more. Further, the twist is gradually increased from the top to the bottom, and the treatment for the twist can be provided without placing a burden on the user.

The summary of the invention described above does not list the features essential to the present invention, and a sub-combination of these features can also be an invention.

(First embodiment of the present invention)
The first embodiment of the present invention will be described with reference to the drawings. 1 is an overall perspective view of the massage machine according to the present embodiment, FIG. 2 is a side sectional view of the massage machine according to the present embodiment, FIG. 3 is a front view of a mechanical unit of the massage machine according to the present embodiment, and FIG. FIG. 5 is a control block diagram of the massage machine according to the present embodiment, FIGS. 6 and 7 are operation timing charts of the massage machine according to the present embodiment, FIG. These are the use effect explanatory views of the massage machine concerning this embodiment.

  In each of the drawings, the massage machine according to the present embodiment as a whole has a backrest 1 that supports the back of the user, a seat 2 that contacts the vicinity of the lower end of the backrest 1 and supports the buttocks of the user, An elbow rest 3 that supports the elbow of the user, a footrest 4 that is pivoted near the tip of the seat 2 and on which the leg under the knee of the user is placed, and a mechanical unit 10 that is housed in the backrest 1 and moves up and down. And a kneading ball unit 50 that is disposed in the mechanical unit 10 so as to be able to advance and retreat in the direction of the user and that can drive the kneading balls. Further, the CPU, the main memory, and the EEPROM are integrally formed, and a substrate on which an element of a microcomputer (hereinafter referred to as a microcomputer) as the control unit 5 is arranged is placed in a space portion immediately below the seat portion 2. ing.

The backrest 1 can be reclined, cushion materials (not shown) can be provided on both ends of the contact surface with the user, and when the user sits down and leans against the backrest 1, the user's back is the center of the backrest 1. It is supposed to be located in. The reclining function of the backrest portion 1 is realized by driving the reclining electric actuator 31 while the backrest portion 1 is rotatably supported by the upper frame 6a. A reclining linear encoder is disposed on the reclining electric actuator 31 so that it can detect how much it has been rotated.
The elbow rest 3 is located on both sides of the seat 2 and joined to the bottom frame 6b, and is formed with a curve so as to stably support the user's forearm even when the backrest 1 reclines. ing. However, the elbow rest 3 having this configuration is not limited, and other elbow rests may be used.

  The footrest (leg part, ottoman, foot placement part) 4 is located on the front end side of the seat part 2, and comprises a right footrest 4a and a left footrest 4b. The right footrest 4a and the left footrest 4b can be tilted in the direction of the leg contact surface of the user. The tilting of the right footrest 4a and the left footrest 4b is realized by the right footrest 4a and the left footrest 4b being rotatably supported in the vicinity of the front end of the seat 2 and driving the electric actuator 8 for the footrest. More specifically, the other end of the right link 7a that connects one end to the bracket of the right footrest 4a and the vicinity of the front end of the upper frame 6a is connected. The right link 7a has a dogleg shape, and the middle portion is connected to the tip of the rod of the electric actuator 8a for the right footrest. By doing so, when the electric actuator 8a is driven and the rod advances, the right link 7a is pushed up, and the right footrest 4a rotates in the upward direction around the connecting portion of the upper frame 6a. On the contrary, when the electric actuator 8a is driven and the rod is retracted from the advanced state, the right link 7a is lowered, and the right footrest 4a is lowered by rotating in the direction opposite to the above-mentioned rotation around the connecting portion of the upper frame 6a. Like the right footrest 4a, the left footrest 4b on the left side is similarly configured, and the right footrest 4a and the left footrest 4b can be independently rotated. The base end portion of the electric actuator 8a for the right footrest is pivotally attached to the lower end portion of a bracket 9a that is suspended downward from the upper frame 6a.

  Within the backrest 1, there is a pair of guide rails 11 and a rack 12 formed along the vertical direction of the backrest 1. Two guide rollers 13, 14, 15, 16 provided on the left and right sides of the mechanical unit 10 are inserted into the guide rail 11, and the mechanical unit is interposed via pinion gears 17, 18 provided adjacent to the guide rollers 14, 16. The movement from the lifting motor 21 disposed on the right assembly base 10 is transmitted and the lifting / lowering can be performed in accordance with the driving of the lifting motor 21. The guide rail 11 is formed in a concave section so that the guide rollers 13, 14, 15, 16 can be inserted. Transmission of motion from the lifting motor 21 is performed by engaging a worm (not shown) formed at the tip of the rotating shaft of the lifting motor 21 with a worm wheel (not shown) attached to the lifting shaft 22. , The rotating shaft (not shown) rotates, the worm rotates, and the engaging worm wheel rotates, so that the rotational force is transmitted to the pinion gears 17 and 18. These worm, worm wheel, and rotating shaft are covered with a gear box. The elevating shaft 22 is disposed so as to be positioned below the mechanical unit 10. The elevating shaft 22 is rotatably supported by a gear box (precisely a bearing covered by the gear box) disposed at the bottom of the right assembly base 19 and a bearing disposed at the bottom of the left assembly base 20. Has been. The bottoms of the right assembly base 19 and the left assembly base 20 are connected by a connecting rod 25 having a concave cross section. The connecting rod 25 has a concave cross section so that the power cable to the various motors and the control cable from the encoder are laid in the concave portion so that the mechanical unit 10 does not interfere with the raising and lowering of the mechanical unit 10 and the back and forth of the kneading ball unit 50. It is to do. The upper side of the right assembly base 19 and the left assembly base 20 is also provided with a hollow rod 26. This is because the central portion of the hollow basket 26 is bent in the back direction so that the rice balls do not contact the hollow basket 26 even when the rice ball unit 50 is retracted. Guide rollers 13 and 15 are rotatably attached to both ends of the hollow rod 26. The hollow rods 26 themselves are fixed by joining portions near both ends to the right assembly base 19 and the left assembly base 20, respectively, and do not rotate. The connecting rod 25 and the hollow rod 26 are joined to the right assembly base 19 and the left assembly base 20 by welding.

  The kneading ball unit 50 is mounted on the lifting shaft 22 and is rotatable about the lifting shaft 22. The rice ball unit 50 includes a right rice ball unit 50a and a left rice ball unit 50b. The right side ball unit 50a and the left side ball unit 50b have a grinding mechanism and a knocking mechanism for transmitting the motions from the grinding motor 51 and the knocking motor 52 to the grinding ball 53, respectively. The gummy ball unit 50 is installed in the housing 54. A rack 55 that is bent so as to have an upper side surface having a predetermined radial distance about the elevating shaft 22 is attached to the upper portion of the housing 54 by screwing at a plurality of positions at predetermined intervals. A pinion gear 56 that engages with the rack 55 is mounted on an advancing / retracting shaft 57 disposed so as to be positioned above the mechanical unit 10. A worm wheel (not shown) is mounted on the advance / retreat shaft 57. A worm (not shown) formed at the tip of a rotating shaft (not shown) of a forward / backward motor 58 disposed on the left assembly base 20 of the mechanical unit 10 is engaged with a worm wheel. These worm wheel, rotating shaft and worm are installed in the gear box. As the advance / retreat motor 58 rotates, the rotating shaft and the worm rotate, and the worm wheel to be engaged rotates. As the worm wheel rotates, the advance / retreat shaft 57 rotates, the pinion gear 56 also rotates along the rack 55 that engages, and the kneading ball unit 50 advances / retreats in the back direction of the user. The advancing / retracting shaft 57 can be rotated by a bearing disposed at the upper part of the right mounting base 19 and a gear box disposed at the upper part of the left assembling base 20 (more precisely, a bearing covered by the gear box). It is supported by.

  Since the right side ball unit 50a and the left side ball unit 50b have the above-described configurations, the right side ball unit 50a and the left side ball unit 50b can advance and retreat independently. Therefore, it is possible to advance so that only the kneading balls 53 of the right kneading ball unit 50a come into contact with the user. There is a connecting body 59 attached to the lifting shaft 22 and the advance / retreat shaft 57. The advance / retreat shaft 57 includes a right advance / retreat shaft 57a and a left advance / retreat shaft 57b, and is respectively supported by a connecting body 59. The other shaft does not follow the rotation of one shaft and independently rotates. That is, the right advance / retreat shaft 57a and the left advance / retreat shaft 57b are not joined.

  A scale is formed on the upper portion of the housing 54 so as to extend in the advancing and retracting direction. A linear encoder is configured together with this scale and a sensor disposed on the back side of the assembly base. The advancing / retreating position can be detected. The forward / backward positions of the right side ball unit 50a and the left side ball unit 50b can be detected by corresponding linear encoders.

  The hitting motor 52 is fixed to the bottom of the housing 54 of the kneading ball unit 50 by screws. A driving pulley is formed at the tip of a rotating shaft (not shown) of the tapping motor 52 inside the housing, and the motion is transmitted to the driven pulley via the transmission belt. The driven pulley is attached to the tip of the hitting shaft. An eccentric rotor is attached to the hitting shaft. The tip of the rod is connected to the rotor, and the rod moves up and down by the rotation of the rotor. The other end of the rod is connected to the kneading ball support arm 77 at a position opposite to the kneading ball mounting position. That is, when the rod is moved up and down, the kneading ball support arm 77 is moved up and down, and the kneading ball 53 is moved up and down in accordance therewith, thereby realizing treatment. That is, the ball mechanism 53 is moved even if it constitutes a crank mechanism and the rotational force from the motor is changed to the motion force in the desired direction. The right side ball unit 50a and the left side ball unit 50b are also configured as described above, and can perform tapping treatment.

  The kneading ball support arm 77 is attached to the middle portion via a rotor eccentric to the kneading shaft. A worm wheel (not shown) is attached to the fir shaft and is engaged with a worm (not shown) formed at the tip of a rotation shaft (not shown) of the fir motor 51. Even if this engagement is performed, the kneading shaft rotates by the rotation of the kneading motor 51, whereby the kneading shaft rotor rotates eccentrically, and the kneading ball support arm 77 also moves in an arc shape. The treatment of the treatment is realized by moving in an arc shape. More precisely, the fir ball support arm 77 is not attached to the rotor so as to be perpendicular to the central axis of the fir shaft, but the tip direction in which the left and right fir ball support arms 77 are attached to the fir ball 53 is determined. It is attached obliquely to the central axis of the fir shaft so as to expand. By doing so, the kneading balls 53 do not turn on a plane perpendicular to the kneading axis, but realize a treatment such as turning that changes the separation distance between the left and right kneading balls 53 while moving in the front-rear direction. The right side ball unit 50a and the left side ball unit 50b also have the above-described configuration, and each side can be treated with rice.

  As shown in FIG. 5, the control unit 5 converts the detection signal into a left side encoder, a left side encoder, a left side advance encoder, a right side encoder, a right side encoder, a right side encoder, a reclining encoder, and a left footrest. Received from encoder, right footrest encoder, and lift encoder. The control unit 5 includes a left fir motor 51b, a left tapping motor 52b, a left advancing / retracting motor 21b, a right fir motor 51a, a right tapping motor 52a, a right advancing / retreating motor 21a, a lifting / lowering motor 21a, a reclining actuator 31, a left footman actuator 8b, Driving control is performed by outputting a driving electric signal (which may be an electric signal by a PWM method) to the right footman actuator 8a. The control unit 5 receives an input signal from a remote control device capable of wireless communication with each other, operates the drive unit to receive the input signal from each input means and perform an operation according to the operation of the user. ing.

  The present massage machine includes a mechanical massage using only the kneading balls 53 of the mechanical unit 10 and a mechanical cooperation massage using the kneading balls 53 and the footrest 4. In the mechanical massage, for example, the mechanical unit 10 is lifted while the fir motor 51 is rotated forward, the mechanical unit 10 is lowered while the fir motor 51 is reversely rotated, and the tapping motor 52 is rotated forward. Swapping, scrubbing while scrambling, acupressure that presses one place, deep lifting, which is a paddle at a position stronger than strong, deep down, which is a paddle at a position stronger than strong, at a position even weaker than weak This is massage with fir tree balls 53, such as stretching to loosen up, stretching while rolling with finger pressure to loosen from the bottom, stretching the entire back to roll the entire back, stretching the back to concentrate on a narrow area.

  There is an automatic course massage that combines the above-mentioned mechanical massages such as sideburning, sideburning, tapping, ripples, acupressure, depth sidelifting, depth sidewalking, brushing, stretching, stretching of the entire back and partial back muscles. An automatic course can be made innumerably depending on the combination, strength, and speed, but in this embodiment, a relaxation course, a refresh course, and a fatigue course are prepared for each part division (whole body, neck / shoulder, waist). Yes. Each massage course is characterized by the use of Momidama 53 as a treatment means, the ease course is weak, the speed is slow and there are many rolling massages, the refresh course is normal and the speed is a fast-paced massage There are many, fatigue courses are set relatively strong, speed is fast and there are many massages.

  The mechanical linkage massage is a massage with the kneading balls 53 and the footrest 4. More precisely, it is a mechanical massage and a massage by moving the footrest 4 up and down. Specifically, when the right footrest 4a rotates and the lower end rises, the left fir ball 53b advances and contacts the back, and conversely, the left footrest 4b rotates and the lower end rises. The right fir ball 53a advances and contacts the back. By doing so, if the former, if the right footrest 4a rises, the left lower leg rises and tries to escape in the form of warping in the right body direction of the user, but the left side ball 53b has advanced It is possible to provide a new treatment in which the right half body of the cage user is pushed out in the forward bending direction and the body of the user can be twisted as a whole. Similarly, in the latter case, when the left footrest 4b rises, the right lower leg rises and tries to escape in the form of warping the left half of the user, but the right fir tree 53a has advanced and is covered. It is possible to provide a new treatment in which the left half of the user is also pushed in the forward bending direction, and the body of the user can be twisted as a whole. As described above, the massage machine according to the present embodiment adopts a configuration in which the right footrest 4a, the left footrest 4b, the right side ball 53a, and the left side ball 53b can be driven independently. Up and down of the footrest 4 includes a simultaneous mode in which the right footrest 4a and the left footrest 4b are aligned and moved up and down, and an independent mode in which the right footrest 4a and the left footrest 4b are moved up and down independently (the alternate mode in which the footrest 4 is alternately moved up and down is also an independent mode). Included).

  FIG. 6 is an operation timing chart of the massage machine according to the present embodiment. The following operations are performed according to the left half of the timing chart. The right advancing / retracting motor 58a and the left footrest electric actuator 8b are simultaneously driven in the forward direction so that the right fir ball unit 50a advances and the right fir ball 53a comes into contact with the back of the user. Support and lift the right leg of the user and twist as described above. This state is maintained for a predetermined time, and then, conversely, the right advance / retreat motor 58a and the left footrest electric actuator 8b are simultaneously driven in the negative direction, the right fir ball unit 50a moves backward, and the right fir ball 53a is treated. The left footrest 4b is lowered and the right lower leg of the user to be supported is also lowered and released from the twist. Next, the left advance / retreat motor 58b and the right footrest electric actuator 8a are simultaneously driven in the forward direction, the left fir ball unit 50b advances, the left fir ball 53b contacts the back of the user, and the right footrest 4a Ascend, lift and support the left lower leg of the user, and twist as described above (see FIG. 8). This state is maintained for a predetermined time, and then, conversely, the left advance / retreat motor 58b and the right footrest electric actuator 8a are simultaneously driven in the negative direction, the left fir ball unit 50b moves backward, and the left fir ball 53b is treated. The right footrest 4a is lowered and the left lower leg of the user to be supported is also lowered and released from the twist.

  The following operations are performed according to the right half of the timing chart. First, the right advancing / retracting motor 58a is driven in the forward direction, the right fir ball unit 50a is advanced, the right fir ball 53a is in contact with the back of the user, and then the left footrest 4b is driven in the forward direction. 4b rises and supports and lifts the right lower leg of the user to twist the upper half of the user clockwise, and then twist the lower half of the user counterclockwise (at least stretch). You can twist your body step by step. In the right half timing chart of FIG. 6, there is a period in which the driving of the right forward / backward moving motor 58a in the positive direction and the driving of the electric actuator 8b for the left footrest overlap, but a configuration in which they do not completely overlap can also be employed. After maintaining the twisted state for a predetermined time, first, the right advance / retreat motor 58a is driven in the negative direction, the right fir ball unit 50a moves backward, and the right fir ball 53a moves away from the back of the user, and then the left The footrest 4b is driven in the negative direction, the left footrest 4b is lowered and the right lower leg of the user is lowered, thereby releasing the upper body of the non-treated person from the twist and then releasing the lower body of the treated person from the twist. Thus, the body of the user can be released from the twist step by step. In this way, treatment can be performed without placing a burden on the body by adding a twist and releasing it from the twist step by step. Next, the operations of the left advance / retreat motor 58b and the right footrest 4a are substantially the same as the operations of the right advance / retreat motor 58a and the left footrest 4b described above, and the description thereof will be omitted. Here, the structure is driven from the advance / retreat motor 58 and then the footrest 4 is driven, but conversely, the footrest 4 can be driven first and then the advance / retreat motor 58 can be driven. In the right half timing chart of FIG. 6, first, the right advance / retreat motor 58a is driven, and then the left footrest 4b is driven. Conversely, the left footrest 4b is driven first, and then the right footrest 4b is driven. A configuration in which the advance / retreat motor 58a is driven can be used, and similarly, the upper half of the user can be twisted clockwise.

  FIG. 7 is an operation timing chart different from FIG. The timing chart for the left half of FIG. 7 is the same as the timing chart for the left half of FIG. The difference is that the elevating motor 21 is driven in accordance with the driving of the advance / retreat motor 58 and the footrest 4. By doing so, when the right advance / retreat motor 58a and the left footrest electric actuator 8b are driven in the positive direction, and simultaneously the lift motor 21 is driven in the negative direction, the right fir ball unit 50a advances and the right fir ball 53a is covered. While abutting on the back of the user, the left footrest 4b is lifted to support and lift the right lower leg of the user, and is twisted as described above. At the same time, the mechanical unit 10 is moved to the guide rail 11 by the lifting motor 21. It can descend along and twist the user more strongly. This state is maintained for a predetermined time, and conversely, the right forward / backward motor 58a and the left footrest electric actuator 8b are driven in the negative direction, and simultaneously, the lifting motor 21 is driven in the positive direction, whereby the right side ball unit 50a. Retreats and the right fir ball 53a is separated from the back of the user, and the left footrest 4b is lowered and the right lower leg of the user to be supported is also released from the twist and is simultaneously released by the lifting motor 21 and the mechanical unit 10 Rises along the guide rail 11 and is more smoothly released from the twist.

  The timing chart for the right half of FIG. 7 is the same as the timing chart for the right half of FIG. 6 except for the right strike motor 52a and the left strike motor 52b. The difference is that the right-stroke motor 52a and the left-stroke motor 52b are performing the stroke treatment with the side kneading balls 53 that have been advanced when the kneading balls 53 have been fully advanced. By doing so, the treatment person is sufficiently twisted, and the treatment with the kneading balls 53 is performed even when the kneading balls 53 are sufficiently leaned, so that a sufficient treatment effect can be obtained.

As shown in FIG. 8, when the left side ball unit 50b advances and the side ball 53b pushes out the right back part of the user, a twist as shown by an arrow α is generated, and the right footrest 4a is lifted to raise the user's right footrest 4a. The left foot is lifted and a twist like arrow β occurs.
Thus, according to the massage machine according to the present embodiment, one of the kneading balls 53 advances and pushes out one back of the user, and the left and right footrests 4 can be moved up and down independently, and the kneading balls 53 that have advanced Since the footrest 4 on the other side is raised, the back of the user 53 is pushed out by the advancement of the kneading balls 53, and the upper body is twisted, and the foot of the user is lifted and the lower leg is twisted. Thus, it is possible to provide a new treatment in which the twist of the upper body and the twist of the lower body are twists in opposite directions, and the body can be twisted better. Further, the kneading balls 53 can be lifted up and down from the vicinity of the upper back to the vicinity of the waist according to the guide rails 11 and 12, and the twist of the upper body can be strengthened by advancing the kneading balls 53 even if the kneading balls 53 are lowered further to the vicinity of the waist. Naturally, the twist of the upper body can be strengthened by increasing the advancement width of the kneading balls 53.

  The air pump 80 communicates with each air cell by a tube. An electromagnetic valve is provided in the vicinity of the tube connection of the air pump 80, and it is possible to control whether or not the voltage is applied to the solenoid constituting the electromagnetic valve, whether or not to open and close, and the size of the opening. . Therefore, the control part 5 can control expansion / contraction of each air cell by performing control with respect to a solenoid valve.

  FIG. 12 is an operation timing chart of the massage machine. According to the left half of this timing chart, first, air is supplied from the air pump 80 to the right back air cell 81a and the right waist air cell 82a, and at the same time, the electric actuator 8b for the left footrest is driven. Then, the right back air cell 81a and the right waist air cell 82a expand to contact the back of the user, and further expand to push the upper left body of the user and twist it clockwise, while the left footrest 4b As the user rises, the user can receive treatment with a sufficient twist by twisting the lower right body counterclockwise. After maintaining the expanded state of the right back air cell 81a and the right waist air cell 82a for a predetermined time and maintaining the raised state of the left footrest 4b, air is exhausted from the right back air cell 81a and the right waist air cell 82a and the left footrest is exhausted. 4b is lowered. By doing so, the clockwise twist of the upper left body and the counterclockwise twist of the lower right body are solved.

  Next, air is supplied from the air pump 80 to the left back air cell 81b and the left waist air cell 82b, and at the same time, the electric actuator 8a for the right footrest is driven. Then, the left back air cell 81b and the left waist air cell 82b expand to contact the back of the user, and further expand to push the upper right half of the user and twist counterclockwise, while the right footrest 4a As the user rises, the user can receive treatment with a sufficient twist by twisting the lower left half of the body clockwise. After maintaining the expanded state of the left back air cell 81b and the left waist air cell 82b for a predetermined time and maintaining the raised state of the right footrest 4a, air is exhausted from the left back air cell 81b and the left waist air cell 82b and the right footrest is exhausted. 4a is lowered. By doing so, the counterclockwise twist of the upper right half and the clockwise twist of the lower left half are solved.

According to the timing chart of the right half of FIG. 12, first, air is supplied from the air pump 80 to the right back air cell 81a, and at the same time, the electric actuator 8b for the left footrest is driven so that the right back air cell 81a is completely During the expansion, air is supplied from the air pump 80 to the right waist air cell 82a. Then, first, the right back air cell 81a expands and the upper left half of the user is gradually twisted clockwise, and the left footrest 4b rises and the lower right half of the user is gradually twisted counterclockwise. At the same time, the right waist air cell 82a can also be inflated to twist the upper left body of the user further clockwise. The back air cell 81 and the waist air cell 82 are inflated in stages as compared with the simultaneous expansion. Thus, the user can slowly twist the upper body of the user and receive treatment without feeling burdened by the user. The right back air cell 81a maintains the inflated state for a predetermined time, and the right waist air cell 82a exhausts air without maintaining the inflated state, and after maintaining the raised state of the left footrest 4b, first, the right back air cell 81a Also exhausts air and lowers the left footrest 4b. By doing so, the twist is solved step by step by unwinding the twist in the reverse procedure of twisting the user, and the user is not burdened.
As described above, according to the massage machine according to the present embodiment, it is possible to provide a treatment for twisting the user, and the air cell has a wider contact surface to the user and expands as compared with the fir ball 53. The air cell has flexibility, and can push the user stably and softly.

(Third embodiment of the present invention)
A massage machine according to a third embodiment of the present invention will be described with reference to the drawings. 13 is an overall perspective view of the massage machine according to the present embodiment, FIG. 14 is a right sectional view of the massage machine according to the present embodiment, FIG. 15 is a control block diagram of the massage machine according to the present embodiment, and FIG. It is an operation | movement timing chart of the massage machine which concerns on a form.
The massage according to the present embodiment includes the mechanical unit 10 disposed with the massage machine according to the first embodiment and the air cell disposed with the massage machine according to the second embodiment. The difference is that the shoulder air cell 86 is disposed at a position where it abuts on the shoulder of the user, and the arm air cell 87 is disposed at a position where it abuts on the arm of the user. Therefore, according to the massage machine which concerns on this embodiment, a user can be provided with mechanical massage and massage by an air cell.

  The shoulder air cell 86 is disposed in a shoulder air cell projecting portion 88 formed so as to project from an intermediate portion of the side surface of the backrest portion 1. The shoulder air cell 86 includes an inner right shoulder air cell 86a (or an inner left shoulder air cell 86c) and an outer right shoulder air cell 86b (or an outer left shoulder air cell 86d), and the outer right shoulder air cell 86b protrudes from the shoulder air cell. 88 and the inner right shoulder air cell 86a is on the user side.

  The arm air cell 87 is disposed in an arm insertion portion 89 having a U-shaped cross section disposed in the middle portion of the upper surface of the elbow rest 3. The arm air cell 87 includes a right arm upper surface air cell 87 a (or left arm upper surface air cell 87 d) disposed on the upper surface of the arm insertion portion 89, and a right arm side air cell 87 b (or left arm) disposed on the side surface of the arm insertion portion 89. Side air cell 87e) and a right arm bottom air cell 87c (or a left arm bottom air cell 87f) disposed on the bottom surface of the arm insertion portion 89.

  FIG. 16 is an operation timing chart of the massage machine. According to this operation timing chart, first, air is supplied from the air pump 80 to the outer right shoulder air cell 86b and the left arm air cells 87d, 87e, 87f to drive the left footrest electric actuator 8b, and the left arm air cell 87d, 87e and 87f are inflated to fix the right arm of the user, and in that state, the outer right shoulder air cell 86b is inflated to push out the upper left half of the user and twist it clockwise, and the left footrest 4b is raised. Twist the lower right half of the user counterclockwise. After the outer right shoulder air cell 86b expands, air is supplied from the air pump 80 to the inner right shoulder air cell 86a, and then air is supplied from the air pump 80 to the right back air cell 81a and the right advance / retreat motor 58a is driven. Then, air is supplied from the air pump 80 to the right waist air cell 82a, and the elevating motor 21 is driven. By doing so, the inner right shoulder air cell 86a, the right back air cell 81a, and the right waist air cell 82a are inflated in sequence, and gradually push the upper left half of the person to be pushed out in a clockwise direction. 50a rotates to the user side, and the kneading balls 53 push out the patient to twist, and the mechanical unit 10 descends in the waist direction which is the center of bending of the body to twist the user. In this way, it is possible to twist more strongly in a stepwise manner, and a sufficient treatment effect can be obtained without placing a burden on the user.

  After sufficiently twisting the body of the user, the air in the right waist air cell 82a is exhausted and the lift motor 21 is driven to lift the mechanical unit 10 away from the vicinity of the waist, thereby to the user. The twist is weakened. The air in the right back air cell 81a is exhausted and the right advance / retreat motor 58a is driven to retreat the mechanical unit 10, and the twist to the user is further weakened. By twisting the air in the inner right shoulder air cell 86a and the outer right shoulder air cell 86b, the twist to the user is weakened. Finally, the left footrest electric actuator 8b is driven, and the footrest 4b is lowered to completely eliminate the twist on the user. Thus, after twisting strongly in steps, the twist is released in steps, so that there is no burden on the body of the non-treatment person and an effective massage effect by the twist can be obtained.

(Other embodiments)
[High-speed operation] In the massage machine according to each of the above-described embodiments, the advancement speed change can be increased immediately before the kneading ball 53 for twisting is located at the most advanced position, so that the user is more balanced. Breaking down, the user can make a passive movement to keep balance. Similarly, the speed change of the expansion of the air cell can be increased immediately before the expansion. Further, the change in the rising speed can be increased immediately before the footrest 4 is positioned at the highest position.

  [Raised position of footrest] In the massage machine according to each of the above embodiments, the raised height of the footrest 4 was not mentioned, but the bottom front end or the rear end of the footrest 4 was higher than the seating surface of the seat 2. It is also possible to give a lower body twist to the user more strongly. As is clear from the timing chart, the footrest 4 is raised by raising either the left or right footrest 4 (the operation of raising one footrest lower and raising the other footrest higher). Even in this case, the angle between the footrests is formed, and the user can receive a twist on the lower body), but the user raises the leg compared to raising both footrests 4 However, when the footrest 4 rises higher than the seat 2 in this way, the burden of raising the legs of the user is large, so the seat 2 itself is divided into left and right, The seat 2 itself can also be tilted independently on the left and right sides, and can be configured to tilt according to the footrest 4, supporting only the lower leg. Compared to the case where higher increase than the seating surface of the footrest 4 in a state, bear no treated person can raise the legs.

  [Cooperation for Twist Treatment by Reclining] In each of the above embodiments, the upper body is twisted by the advancement / retraction of the kneading ball unit 50, the treatment of the kneading ball 53, the air cell, and the footrest 4 is raised. Furthermore, these twists can be caused more strongly in the user by raising the reclining and making it cooperate.

  [Interlocked driving of footrest and air cell] In the overall configuration of the third embodiment (not limited to this configuration, the left and right footrests can be moved up and down independently, and an air cell for sandwiching the lower leg is disposed in the footrest. The footrest air cell 83 is inflated when the footrest 4 is raised, the footrest air cell 83 is contracted when the footrest 4 is lowered, and the left and right footrests 4 are alternately raised and lowered alternately. It can promote blood circulation of the lower leg. Further, when one footrest 4 is lifted, it is possible to gradually supply air, tighten the crus to the maximum when it is located at the highest ascending position, and conversely exhaust it when the footrest 4 is lowered. Can promote blood circulation of the lower leg. Furthermore, while maintaining the state in which the air cell 83 for footrest is inflated, the left and right footrests can be alternately raised and lowered, the legs can be stretched, and the user can be relaxed.

  [Rotation with the left and right footrests aligned] The footrest 4 can be raised and lowered with the left and right sides aligned. When raising and lowering with the left and right aligned, it is desirable to make the ascending / descending speed and acceleration smaller than when raising and lowering independently. This is because when the footrests are lifted and lowered together, the user's degree of freedom is smaller than when the footrests are lifted and lowered independently, so that the user is burdened by moving the footrest quickly.

  [Reciprocal rotation of a predetermined angle around a predetermined formation angle of the footrest] As shown in FIG. 17A, the right footrest 4a and the left footrest 4b are raised, and the formation angle α formed by the two footrests is It can be maintained, and a relaxed posture can be provided to the user. Further, from the state in which the right footrest 4a and the left footrest 4b are shifted in this way, each can be moved up and down within the β angle and up and down within the γ angle. By doing so, it is possible to exercise with relaxation for the user. Further, by applying such an operation to each of the embodiments, it is possible to exercise while twisting the user. Furthermore, the formation angle α can be set as an opening angle, and the right footrest 4a and the left footrest 4b can be moved up and down within the opening angle, and a pseudo walking motion can be provided to the user. Here, if the opening angle α is large, it becomes a pseudo walking motion with a large stride, and if the opening angle β is small, it becomes a pseudo walking motion with a small stride.

 [Leg insertion prevention structure] In each of the above embodiments, since the footrest 4 has a U-shaped cross section (see FIG. 17B), the legs are surrounded by the left and right side walls while the user puts his / her legs on. Even if the right footrest 4a and the left footrest 4b are moved up and down independently, if the lower leg of the user is up to a certain height between the back of one footrest and the front of the other footrest, it is safe without being caught. . Thus, as long as it is only for preventing pinching of the lower leg by the footrest 4, it can respond also by using the footrest (refer FIG.17 (c)) of L-shaped cross section. Further, the footrest 4 can be formed in an H-shaped cross section (see FIG. 17D), and even when the opening angle is larger than the height of the inner side wall of the footrest 4, the lower leg can be sandwiched. Safer. Further, the footrest 4 having an H-shaped cross section can be improved to have a shape (see FIG. 17 (e) showing the cross-sectional shape) in which the back portion of the outer side wall is deleted.

  [Raising speed of descending rotation of footrest] The upper and lower sides of the footrest 4 are realized by an actuator using a motor, and the ascending speed and descending speed of the footrest 4 are substantially the same. On the other hand, it can be made faster and blood circulation of the lower leg can be further promoted. The speed change can be adjusted by changing the voltage level to the motor. Further, as shown in FIG. 18, a bellows-like flexible air bag 90 is used instead of an actuator using a motor as a drive unit for raising and lowering the footrest 4, and gas is supplied to and exhausted from the air bag 90. It can also be configured to perform at high speed. With such a configuration, the footrest 4 can be dropped at high speed by quickly exhausting the gas in the airbag 90 (the “stone” and the footrest 4 can be dropped). For example, as compared with the case where the footrest 4 is moved up and down using a transmission mechanism using gears, it is possible to move up and down at a high speed and to easily make the speed and acceleration when rising and lowering different.
