  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. FIG. 1 and FIG. 2 show an example of a passive exercise apparatus according to an embodiment of the present invention. In this example, the passive exercise equipment is a standing-type passive exercise equipment in which both feet are placed in a posture in which the user stands up, and the support base portion on which the user can place the soles of both feet. 2, a plurality of airbags 5 arranged for each portion of the upper surface of the support base 2 where the sole of the user hits, and a pump device (not shown) for supplying and exhausting air to inflate and contract the airbags 5. 2).

  The upper surface of the support base 2 is flat and wide enough to allow the user to place his / her feet and maintain a stable standing posture. Foot-shaped markings are applied. The plurality of airbags 5 are arranged in a planar shape so as to cover substantially the entire portion where the marking is applied.

  Specifically, as the plurality of airbags 5, a pair of toe part airbags 5a arranged side by side so as to hit the toe part and a pair of left and right side parts so as to hit the front foot part are provided. Forefoot airbag 5b, middle foot airbag 5c provided in two pairs in the front, rear, left and right so as to hit the arch, and a pair of rear foot airbags arranged side by side so as to hit the heel 5d are arranged in a matrix on the front, rear, left and right.

  Each of these airbags 5 constitutes an actuator in which the top is applied to the sole of the user and the top is movable up and down. That is, the toe portion airbag 5a is an actuator that can freely set the top and bottom positions of the top portions where the toe portions of the five toes will hit. The forefoot airbag 5b is an actuator that can freely set the vertical position of the top where the forefoot bottom portion will hit. The midfoot airbag 5c is an actuator that can freely set the vertical position of the top portion where the arch will hit. The rear leg airbag 5d is an actuator that can freely set the vertical position of the apex where the heel portion will hit.

  In addition, you may use another structure as such an actuator. As another configuration, for example, a configuration in which a protrusion that can slide up and down is disposed so as to contact a predetermined part of the sole and the protrusion is driven up and down is conceivable. When this projection body is used, it is preferable to use an actuator that slides the projection body up and down using a motor and a gear, particularly in places where weight is applied.

  Each of these airbags 5 is controlled to perform a cooperative operation by supplying and exhausting air from the pump device, and a plurality of uneven patterns can be formed and freely changed by the top of each airbag 5. . And, the user puts the soles of both feet on this variously formed uneven patterns and maintains the standing posture, thereby stimulating the muscles of both feet and exerting the force of stroking while maintaining balance. You can train efficiently.

  As the concavo-convex pattern, the airbag 5 on the front side expands greatly (for example, the toe airbag 5a, the forefoot airbag 5b, the midfoot airbag 5c, and the rearfoot airbag 5d in this order). When set so that the vertical position of the top portion is lowered, the user who puts his sole on the concave / convex pattern is bent back (see FIG. 2A). Further, as the concavo-convex pattern, the rear airbag 5 is inflated as much as possible (for example, a toe airbag 5a, a forefoot airbag 5b, a midfoot airbag 5c, and a rearfoot airbag 5d). When the setting is made so that the vertical position of the top portion becomes higher in this order), the user who puts the sole on the concave / convex pattern is bent down (see FIG. 2B).

  Further, when the midfoot airbag 5c located at the center portion in the front-rear direction is inflated and controlled so that the top portion protrudes greatly upward, the user who puts his sole on the uneven pattern is Is curved in an arch shape (see FIG. 2C).

  Furthermore, since the toe airbag 5a, the forefoot airbag 5b, the midfoot airbag 5c, and the rear foot airbag 5d are all arranged side by side, If the top and bottom positions are different, an inward or outward slope can be added. For example, in each airbag 5a, 5b, 5c, 5d where the left sole is placed, when the left top is set at a lower vertical position than the right top, an inclination to the outside is added to the left foot. Can do. When the top of the right side is set at a lower vertical position than the top of the left side, an inward tilt can be applied to the left foot.

  In addition, in each airbag 5a, 5b, 5c, 5d at the position where the right sole is placed, when the right apex is set at a lower vertical position than the left apex, the right leg is inclined outward. Can do. When the left top is set at a lower vertical position than the right top, it is possible to apply an inward tilt to the right foot.

  Various combinations of these concavo-convex patterns are conceivable and can be set as appropriate. Then, while the feet are placed on the concavo-convex pattern and the standing posture is maintained, the pump device automatically inflates and contracts each airbag 5 and switches the concavo-convex pattern, thereby making it difficult for the elderly to exercise rapidly. Even a user such as a person can stimulate the muscles of both feet while maintaining balance and train his / her stroking force reasonably and efficiently.

  The airbag 5 does not have to include all of the illustrated examples. If at least the toe portion airbag 5a that hits the toe portion is disposed, all the toe portion airbags 5a are inflated. It is possible to cause dorsiflexion or to inflate each toe part airbag 5a to perform bending and stretching movements for each finger. Further, if the midfoot airbag 5c that hits at least the arch portion is disposed, these can be inflated so that the legs are curved in an arch shape.

  Also, if at least the toe portion airbag 5a that hits the toe portion and the rear foot portion airbag 5d that hits the heel portion are arranged, the toe portion airbag 5a is inflated and the foot is bent back. In addition, it is possible to incline the foot by inflating the rear foot airbag 5d.

  3 to 12 show other examples of passive exercise equipment in the embodiment of the present invention. In addition, detailed description is abbreviate | omitted about the structure similar to the above-mentioned example structure among the structures of this example, and only the characteristic structure different from an example is explained in full detail below.

  In the passive exercise apparatus of this example, the support base 2 on which the user's feet are placed is formed using the left foot support 2a and the right foot support 2b on which the left and right feet of the user are respectively placed. The airbags 5a, 5b, 5c, and 5d are disposed on the footrest plates 21 described later of the left foot support 2a and the right foot support 2b, respectively. In the drawings excluding FIG. 3 and FIG. 9, illustration of the airbags 5a, 5b, 5c, and 5d is omitted.

  The passive motion apparatus of this example includes a driving device 3 that reciprocally moves the left foot support 2a and the right foot support 2b. The left foot support 2a and the right foot support 2b are provided with the airbags 5a, 5b, 5c, It is provided to operate in coordination with 5d expansion / contraction. Therefore, the passive movement shown in the example of stimulating muscle groups while maintaining a standing posture while balancing on the uneven pattern formed by each of the airbags 5a, 5b, 5c, 5d, and the left and right legs are forced It is possible to combine with other reciprocating movements of reciprocating along a predetermined locus to stimulate various muscle groups of the legs. Hereinafter, the left foot support 2a and the right foot support 2b, and the drive device 3 that reciprocates the left foot support 2a and the right foot support 2b will be described in detail.

  In this example, as shown in FIG. 3 and FIG. 4, a base plate 1 a is provided as a mount for placing on the floor. Although the base plate 1a has a rectangular parallelepiped shape, the outer peripheral shape of the base plate 1a is not particularly limited. Hereinafter, in order to simplify the description, it is assumed that the upper surface of the base plate 1a is parallel to the floor surface in a state where the base plate 1a is placed on the floor. Therefore, the top and bottom in FIGS. 3 and 4 are the top and bottom when in use.

  An upper plate 1b is disposed above the base plate 1a, and the housing 1 is formed by joining the base plate 1a and the upper plate 1b. On the base plate 1a, there are arranged a left foot support 2a and a right foot support 2b on which the user puts left and right feet, and a driving device 3 for moving the positions of the left foot support 2a and the right foot support 2b, respectively. . The direction of the arrow X in FIGS. 3 and 4 is the front. In other drawings, when the arrow X is described, the direction is the front.

  The upper plate 1b is provided with two opening windows 11a and 11b that expose the left foot support 2a and the right foot support 2b in the thickness direction. Each opening window 11a, 11b opens in a rectangular shape. However, each opening window 11a, 11b has a center line along the longitudinal direction inclined with respect to the front-rear direction of the housing 1, and the distance between both center lines is larger on the front end side of the housing 1 than on the rear end side. It is formed as follows.

  As shown in FIG. 5, slide grooves 12 are opened on both sides in the width direction of the respective opening windows 11a and 11b so as to face the inside of the opening windows 11a and 11b. A flange portion 22b formed on the footrest cover 22 is slidably inserted into the slide groove 12. The footrest cover 22 constitutes the left foot support base 2a and the right foot support base 2b together with the footrest plate 21 for placing the sole of the foot, and has a main body portion 22a formed in a rectangular cylinder shape, The flange portion 22b extends over the entire circumference of the main body portion 22a along one opening surface (upper surface) of the main body portion 22a. A mounting plate 22c is integrally formed in the lower portion inside the main body portion 22a of the footrest cover 22.

  The main body portion 22a is formed so that the dimension in the longitudinal direction and the dimension in the width direction are smaller than those of the opening windows 11a and 11b. The flange portion 22b is formed so that the dimension in the longitudinal direction and the dimension in the width direction are larger than those of the opening windows 11a and 11b. Furthermore, the distance between the bottoms of the slide groove 12 is formed larger than the distance between the front end edges of the flange portion 22b. Therefore, the footrest cover 22 can move in the range of the slide groove 12 in the width direction, and can also move in the longitudinal direction.

  The footrest plate 21 is formed in a rectangular plate shape that is slightly smaller than the inner peripheral edge of the main body portion 22a of the footrest cover 22, and is formed to have a size that can place the entire foot of the user. Cover bodies 21 a and 21 b bent in a U-shape are integrally provided on the lower surface peripheral portion of the footrest plate 21. Further, a pair of bearings 21 c that are spaced apart in the width direction of the footrest plate 21 are provided integrally with the footrest plate 21 on the lower surface of the footrest plate 21 and surrounded by the cover bodies 21 a and 21 b.

  A bearing plate 23 having a U-shaped cross section opened upward is fixed to the upper surface of the mounting plate 22 c provided on the foot cover 22. The bearing 21 c provided on the footrest plate 21 abuts on the outer surface of each leg piece 23 a of the bearing plate 23. Furthermore, the shaft part 24 which passes both the leg pieces 23a and the both bearings 21c of the bearing plate 23 is provided. Accordingly, the shaft portion 24 is disposed along the width direction of the footrest plate 21, and the footrest plate 21 rotates around the shaft portion 24 so that the longitudinal direction of the footrest cover 22 moves up and down. It becomes possible. The above-described cover bodies 21 a and 21 b prevent a gap from being generated between the lower surface of the footrest plate 21 and the footrest cover 22 when the footrest plate 21 rotates with respect to the footrest cover 22. Provided.

  A carriage 41 having a U-shaped cross section with the lower surface opened is attached to the lower surface of the mounting plate 22 c provided on the foot cover 22. Two wheels 42 are attached to the outer surfaces of both leg pieces 41 a of the carriage 41. Two rails 43 are fixed to the upper surface of the base plate 1 a for the left foot support 2 a and the right foot support 2 b, respectively, and the wheel 42 is in a rail groove 43 a provided on the upper surface of the rail 43. A carriage 41 is placed on the rail 43 so as to roll. Further, a derailment prevention plate 44 is fixed to the upper surface of the rail 43 in order to prevent the wheels 42 from falling off the rail groove 43a (see FIG. 6).

  By the way, the longitudinal direction of the rail 43 is different from the longitudinal direction of the opening windows 11 a and 11 b provided in the housing 1. As described above, the opening windows 11 a and 11 b are inclined such that the center line in the longitudinal direction is larger at the front end side of the housing 1 than at the rear end side, and the longitudinal direction of the rail 43 is also the front-rear direction of the housing 1. Is similarly inclined to.

  However, in the rail 43, the angle with respect to the front-rear direction of the housing 1 is further larger than the opening windows 11a and 11b. For example, if the angle of the housing 1 with respect to the longitudinal direction is 30 degrees in the longitudinal direction of the opening windows 11a and 11b, the longitudinal direction of the rail 43 is set to 45 degrees. That is, when the feet are placed on the left foot support 2a and the right foot support 2b and the center line of the foot is aligned with the longitudinal direction of the opening windows 11a and 11b, the left foot support 2a and the right foot support 2b are aligned along the rail 43. The longitudinal direction of the rail 43 is set in such a direction that no shearing force acts on the knee even if the position of the foot is changed by moving. In the present embodiment, as a desirable operation, an example is shown in which the left foot support 2a and the right foot support 2b move along a moving path that combines the front-rear direction and the left-right direction. However, depending on the direction in which the rail 43 is disposed, The left foot support 2a and the right foot support 2b can be moved in the front-rear direction and the left-right direction.

  With the above-described configuration, the left foot support 2 a and the right foot support 2 b can reciprocate along the longitudinal direction of the rail 43. Since the longitudinal direction of the rail 43 is inclined with respect to the center line in the longitudinal direction of the opening windows 11a and 11b, the footrest plate 21 and the footrest cover 22 are within the opening windows 11a and 11b with respect to the longitudinal direction. It will move in the crossing direction. That is, the cart 41, the wheels 42, the rails 43, and the anti-wheel removal plate 44 described above function as the guide portion 4 that restrains the movement path of the left foot support 2a and the right foot support 2b.

  As shown in FIG. 7, the driving device 3 that moves the left foot support 2a and the right foot support 2b transmits a drive source 31 that generates a driving force and the driving force to the left foot support 2a and the right foot support 2b, respectively. Thus, there are a system separation unit 32 that separates into two systems, and a reciprocating drive unit 33 that reciprocates the carriage 41 along the rail 43 using a driving force. In the present embodiment, a configuration is adopted in which the driving force is separated by the system separating unit 32 as shown in FIG. 7A and the separated driving force is transmitted to the reciprocating driving unit 33, but the reciprocating driving unit is used as shown in FIG. 7B. It is also possible to separate the driving force of the reciprocating drive obtained by 33 into two systems by the system separating unit 32.

  The drive device 3 will be described more specifically. The drive source 31 employs a rotary motor (hereinafter simply abbreviated as “motor” and uses reference numeral 31), and a system separation unit 32 is connected to the output shaft 31 a of the motor 31.

  The system separation unit 32 includes a worm (first gear) 32a connected to the output shaft 31a of the motor 31 and a pair of worm wheels (second gear) 32b meshing with the worm 32a. The worm 32a and the two worm wheels 32b are housed in a gear box 34 fixed to the base plate 1a. The gear box 34 is formed by a gear case 34a having an opening on the upper surface and a lid plate 34b that is covered by the opening surface of the gear case 34a. A pair of bearings 32c that support both ends of the worm 32a in the longitudinal direction are attached between the gear case 34a and the cover plate 34b.

  The worm wheel 32b is inserted into the rotating shaft 35 held by the gear case 34a and the cover plate 34b, and the rotating shaft 35 rotates with the rotation of the worm wheel 32b. Are combined. A coupling portion 35 a having a non-circular cross section (rectangular shape in the illustrated example) is formed at the upper end portion of the rotating shaft 35.

  The motor 31 is mounted on a mouth receiving portion 34c provided on the gear case 34a and a mouth receiving plate 13a fixed to the base plate 1a, and is coupled to a lid plate 34b and a mouth receiving plate 13a that are covered by the gear case 34a. The holding plate 13b is fixed to the base plate 1a.

  As shown in FIG. 8, the reciprocating drive unit 33 includes a crank plate 36 having one end coupled to the coupling portion 35 a of the rotating shaft 35, and a crank rod 38 coupled to the crank plate 36 via a crank shaft 37. Prepare. One end of the crankshaft 37 is fixed to the crank plate 36, and the other end of the crankshaft 37 is held by a bearing 38 a held by one end of the crank rod 38. That is, one end portion of the crank rod 38 is rotatably coupled to the crank plate 36. The other end of the crank rod 38 is coupled to the carriage 41 using a shaft body 38b, and the other end of the crank rod 38 is coupled to the carriage 41 so as to be rotatable.

  As is apparent from the above-described configuration, the crank rod 38 functions as a conversion mechanism that converts the rotational force of the worm wheel 32 b into the reciprocating movement of the carriage 41. The crank rod 38 is provided for each worm wheel 32b, and the carriage 41 is provided separately for the left foot support 2a and the right foot support 2b. Therefore, the crank rod 38 functions as a conversion mechanism that converts the rotational force of the worm wheel 32b into reciprocal movement between the left foot support 2a and the right foot support 2b.

  Since the movement path of the carriage 41 is restricted by the wheels 42 and the rails 43 as described above, the carriage 41 reciprocates along the longitudinal direction of the rails 43 as the worm wheel 32b rotates. That is, the rotation of the motor 31 is transmitted to the crank plate 36 via the worm 32 a and the worm wheel 32 b, and the carriage 41 is reciprocated on a straight line along the rail 43 by the crank rod 38 coupled to the crank plate 36. Is done. As a result, the footrest cover 22 coupled to the carriage 41 reciprocates along the rail 43. That is, the left foot support 2 a and the right foot support 2 b reciprocate in the longitudinal direction of the rail 43.

  In the present embodiment, the driving force is separated into two systems by the worm 32a and the two worm wheels 32b and used as the driving force of the left foot support 2a and the right foot support 2b for each system. The left foot support 2a and the right foot support 2b are driven in association with each other. Here, the position where each worm wheel 32b meshes with the worm 32a is changed by 180 degrees, and therefore when the left foot support 2a is located at the rear end of the movement range, the right foot support 2b is located at the front end of the movement range. . The rear end in the movement range of the left foot support 2a is the right end of the movement range of the left foot support 2a, and the front end in the movement range of the right foot support 2b is the right end of the movement range of the right foot support 2b. The left foot support 2a and the right foot support 2b move in the same direction.

  As is clear from the above-described configuration, a phase difference in the movement of the left foot support base 2a and the right foot support base 2b can be appropriately given according to the position where the worm 32a and the worm wheel 32b are engaged with each other. is there. When standing and standing on the left foot support 2a and the right foot support 2b, if the phase difference of 180 degrees is given as in the present embodiment, the user moves the center of gravity in the front-rear direction less. Therefore, it can be used even by users who have poor balance function. Alternatively, if there is no phase difference, the center of gravity moves in the front-rear direction of the user, so it is not just a movement of the muscles of the legs, but also muscles such as the back of the back to maintain the balance function Also useful for exercise.

  By the way, since the footrest plate 21 provided on the left foot support 2a and the right foot support 2b can be rotated around the shaft portion 24 with respect to the footrest cover 22, as shown in FIG. It is possible to change the height positions of the front end portion and the rear end portion. In other words, by changing the height positions of the toes and heels of the foot placed on the footrest plate 21, the ankle joint can be bent and dorsiflexed.

  Here, in order to interlock the rotation of the footrest plate 21 around the shaft portion 24 with the reciprocating movement along the rail 43, the base plate 1a has a movement of the footrest plate 21 as shown in FIG. A guide surface 14 having an inclined surface 14 a at least partially along the path is formed, and a copying projection 25 that contacts the guide surface 14 is provided on the lower surface of the footrest plate 21. In the illustrated example, an inclined surface 14a that is inclined at a constant angle with respect to the upper surface of the base plate 1a is formed over the entire length of the guide surface 14, but the shape of the guide surface 14 is not particularly limited. It suffices that the part includes the inclined surface 14a. The material and shape of the tip of the copying projection 25 may be selected so that the coefficient of friction with respect to the guide surface 14 is small. In this embodiment, the roller 25a that rolls on the guide surface 14 is It is provided at the tip of the copying projection 25.

  As described above, by providing the copying projection 25 that contacts the guide surface 14, the copying projection 25 is used when the left foot support 2a and the right foot support 2b reciprocate as the motor 31 rotates. Is in contact with the inclined surface 14 a provided on the guide surface 14, the angle of the footrest plate 21 with respect to the base plate 1 a changes as the footrest plate 21 rotates around the shaft portion 24. Ankle plantar flexion and dorsiflexion are performed.

  In the above example, the guide surface 14 is provided on the base plate 1a and the copying projection 25 is provided on the footrest plate 21, but the guide surface 14 is provided on the footing plate 21 as shown in FIG. Even if the portion 25 is provided on the base plate 1a, the same operation is performed.

  In the configuration example described above, as the configuration of the system separation unit 32 in the drive device 3, by using the worm 32a and the worm wheel 32b, a right angle axis between the output shaft 31a of the motor 31 and the rotary shaft 35 that rotates together with the worm wheel 32b. Although an example of a configuration in which the transmission between the output shaft 31a of the motor 31 and the rotation shaft 35 is transmitted by a belt may be employed. In this case, instead of the worm wheel 32b, a pulley around which a belt is wound can be used, and the worm 32a can be omitted.

  In the above configuration example, the output shaft 31a of the motor 31 is arranged along the upper surface of the base plate 1a. However, when the output shaft 31a is arranged so as to be orthogonal to the upper surface of the base plate 1a, It is possible to transmit the rotational force and separate the system by a combination of spur gears instead of a combination of 32a and worm wheel 32b. In this configuration, the spur gear can be replaced with a pulley, or the rotational force can be transmitted between the pulleys with a belt.

  By the way, when using the device in a standing position, the left and right feet are placed on the left foot support 2a and the right foot support 2b, respectively, in the initial position where the left foot support 2a and the right foot support 2b are stopped. Then, the operation of the drive device 3 is started. As shown in FIG. 12, the longitudinal direction Dx of the left foot support 2a and the right foot support 2b is disposed so as to form an angle of, for example, about 9 degrees with respect to the front-rear direction (the direction of the arrow X). When the user stands on the right foot support 2b, the user's leg is not twisted and is in a natural standing position.

  In the initial position, the left foot support 2a and the right foot support 2b are located at the same position in the front-rear direction. That is, at the initial position, the left foot support 2a and the right foot support 2b are aligned on a straight line in the left-right direction. Accordingly, when the user sits on the left foot support 2a and the right foot support 2b at the initial position, the straight line drawn from the center of gravity of the user in the vertical direction is substantially between the left foot support 2a and the right foot support 2b. You will pass through the center.

  As is apparent from the above-described configuration, when the driving device 3 starts to operate, the left foot support 2a and the right foot support 2b change their positions in the front-rear direction, and in the left-right direction as the position changes in the front-rear direction. Change the position. Here, the left foot support 2a and the right foot support 2b reciprocate on a straight line along the rail 43, and the left foot support 2a and the right foot support 2b move in a direction different from the front-back direction of the foot. For example, it moves in a direction that forms 45 degrees with respect to the front-rear direction of the housing 1. This moving distance is set to 20 mm, for example.

  As described above, the footrest plate 21 rotates around the shaft portion 24 at the same time as the left foot support 2 a and the right foot support 2 b reciprocate along the rail 43. When the footrest plate 21 moves forward, the copying projection 25 rises on the inclined surface 14a of the guide surface 14. Therefore, the ankle joint is bent back at the front end positions of the left foot support 2a and the right foot support 2b, and the left foot is supported. The ankle joint is bent at the rear end position of the base 2a and the right foot support base 2b. The position of the shaft portion 24 is set in the vicinity of the heel on the sole, and the angle between the bottom flexion and the dorsiflexion is set to about 10 degrees with respect to the reference plane with respect to the upper surface of the base plate 1a.

  The relationship between the front and back positions of the left foot support 2a and the right foot support 2b and the bottom flexion and dorsiflexion can be reversed from the above example. Further, the angle of the bottom flexion and the dorsiflexion with respect to the reference plane may be varied. These operations can be easily realized by appropriately setting the shape of the guide surface 14.

  As described above, in the passive exercise apparatus of this example, an example in which the muscle group is stimulated by maintaining a standing posture while balancing on the uneven pattern formed by the airbags 5a, 5b, 5c, and 5d. It is possible to combine the other movement shown in Fig. 6 with another movement that forces the left and right feet to reciprocate along a predetermined trajectory by the drive device 3 to stimulate various muscle groups of the legs. It is.

  Various combinations of these passive movements can be considered. In other words, the uneven pattern of each airbag 5a, 5b, 5c, 5d stimulates the muscle groups of both legs by holding the standing posture while making the legs dorsally bent, buckled, arched curved, inwardly inclined, outwardly inclined, etc. There are various combinations of the passive movement of giving and the other movement of giving stimulation to the muscle groups of both legs by the reciprocating movement, buckling, dorsiflexion, etc. of the left foot support 2a and the right foot support 2b itself. Will be.

  In addition, while maintaining the user's foot in a dorsiflexed state by the uneven pattern of each airbag 5a, 5b, 5c, 5d, the drive device 3 causes the dorsiflexion at the front end position as described above, and at the rear end position. When the left foot support base 2a and the right foot support base 2b are reciprocated so as to be bent, the bottom buckling at the rear end position is offset by the back bending due to the concave and convex pattern so as to be substantially horizontal, and the front foot position is greatly bent back. Can do. In addition, when the left foot support 2a and the right foot support 2b are reciprocated as described above by the driving device 3 while the user's foot is kept buckled by the uneven pattern, the dorsiflexion at the front end position is performed. Can be offset by buckling by the concavo-convex pattern to be substantially horizontal, and can be greatly buckled at the rear end position. Such switching of the passive motion can be easily achieved by supplying and exhausting the airbags 5a, 5b, 5c and 5d.

  Moreover, in the above-described other exercise equipment, the airbags 5a, 5b, 5c, and 5d may not be inflated and contracted. That is, in the above-described configuration, each airbag 5a, 5b, 5c, 5d is an actuator that drives the top portion thereof in the vertical direction, and each airbag 5a, 5b, 5c, 5d is on the sole of the user. In contrast, an external force is actively applied. On the other hand, the airbags 5a, 5b, 5c, and 5d are not supplied and exhausted with air, and the airbags 5a, 5b, 5c, and 5d are moved to the user's feet according to the pressing of the soles of the users. The external force (reaction force) may only be passively applied to the back pushing.

  Even in this case, the balance of the user can be variously broken by the reaction force passively exerted by each airbag 5a, 5b, 5c, 5d during exercise. Therefore, by holding a foot on the airbag 5 and maintaining a standing posture, even a user such as an elderly person who has difficulty in rapid exercise can stimulate and stretch the muscles of both feet while maintaining balance. Can be trained effortlessly and efficiently. There is no need to provide a plurality of airbags 5 that do not inflate and contract like the illustrated airbags 5a, 5b, 5c, and 5d, and a single configuration may be provided where the soles touch. .

  In order to passively exert an external force (reaction force) on the user as described above, an elastic member other than the airbag 5 may be similarly arranged. As the elastic member disposed here, any elastic member that is elastically deformed and exerts a reaction force by pressing the sole of the user's foot can be applied. For example, an elastic member made of a foam material such as sponge is preferably used. Used.

  The embodiment of the present invention is an exemplification, and it is needless to say that various substitutions, modifications, and changes can be made without departing from the technical idea of the present invention.
