- This invention relates to a passive exercise assisting device for training muscles of lower legs.
- Japanese registered utility model application publication No. 3112751 and Japanese patent application publication No. 2002-253700 discloses the prior exercise assisting device for training the muscles of the lower legs. The prior exercise device of stepping type is a device which is used for easily training the muscles of the user's lower leg in the home. The prior exercise assisting device of the stepping type comprises a left foot support, a right foot support, springs and air cylinders. The user places a user's left foot and a user's right foot feet on the left foot support and the right foot support respectively. Subsequently, the user alternately moves the user's left foot and the right foot up and down. In this manner, the user uses the exercise assisting device of the stepping type. By using the exercise assisting device of the stepping type, the user is able to perform exercise similar to the walking. Consequently, the user is able to promote the user's health.
- However, the user is required to step the left foot support and the right foot support oneself when the user uses the prior exercise assisting device. When the user steps the left foot support and the right foot support of the prior exercise assisting device, the user bends and stretches the knee joint. Therefore, persons having knee pains or aged parsons have difficulty in using the prior exercise device of stepping type. In addition, the user of the prior exercise device of stepping type is required to move actively. That is, the user of the prior exercise device is needed to carry on the exercise with an effort. This effort is a burden to the user. Furthermore, the user does not amuse a simple up-down motion of the left foot and the right foot support. Therefore, the user gives up the exercise easily.
- This invention is achieved to solve the above problem. An object of this invention is to produce the passive exercise assisting device of standing type. The passive exercise assisting device of standing type gives passive exercise of the up-down motion to the left leg and the right leg in order to train balance of the user's body and also train the muscle of the lower legs.
- In order to solve the above problem, the passive exercise assisting device in this invention comprises a left foot support, a right foot support, and a driving unit. The left foot support and the right foot support are shaped to bear a left foot and a right foot of the user respectively. The driving unit is configured to move the left foot support and the right foot support so as to give motions to respective the left foot support and the right foot support in relation with each other. The driving unit comprises at least one of a horizontal motion applying mechanism and a rotation motion applying mechanism. In addition, the driving unit comprises a vertical motion applying mechanism. The horizontal motion applying mechanism is configured to give horizontal motion to the left foot support and the right foot support in order to move the left foot support and the right foot support. The rotation motion applying mechanism is configured to give a rotation motion in order to rotate respective the left foot support and the right foot support about a horizontal axis along the horizontal direction. The vertical motion applying mechanism is configured to give vertical motions in synchronization with the horizontal motions or the rotation motions to the left foot support and the right foot support in order to move the left foot support and the right foot support in a vertical direction as the left foot support and the right foot support is moved by the horizontal motion applying mechanism or is rotated by the rotation motion applying mechanism.
- In this case, the passive exercise assisting device of standing type is configured to slide the user's left foot and the right foot along a horizontal direction passively by means of the horizontal motion applying mechanism in a condition where the user stands on the left foot support and the right foot support. Alternatively, the passive exercise assisting device of standing type is configured to rotate the user's left foot and the right foot support about the respective horizontal axes in order to dorsiflex the ankle joints passively in a condition where the user stands on the left foot support and the right foot support. In addition, the horizontal slide motion or the rotation motion causes weight shift of the user. Therefore, the vertical motion applying mechanism is configured to give the vertical motions in synchronization with the horizontal slide motion or the rotation motions to the left foot support and the right foot support. Consequently, the user is able to enhance balance ability by putting the user's weight on the foot support, while the user moving the left femoral area and the right femoral area alternately. In addition, the balance ability, the capacity to support the user's weight by either one of the left leg or the right leg, and the capacity of the muscle of the lower leg are enhanced simultaneously by swinging the user's body leftward and rightward in order to break the user's balance, whereby the user is able to take exercise continuously with interest. Furthermore, the passive exercise assisting device gives the 3-dimensional exercise which includes a vertical motion in combination with the horizontal motion. Therefore, an exercise effect which is given to the lower leg is enhanced. Moreover, even the passive exercise assisting device gives the 3-dimensional exercise, the passive exercise assisting device hardly bend and stretch the knee joint. Therefore, the passive exercise assisting device allows the user to train the muscles of the legs of the user without risk of making an impact to the knee joint.

- It is preferred that the vertical motion applying mechanism comprises a vertical motion applying means. The vertical motion applying means is configured to move the left foot support and the right foot support in the vertical direction. The vertical motion applying means is configured to vary height of the left foot support in relation to the right foot support.
- In this case, the vertical motion applying means is configured to give a seesaw motion to the left foot support and the right foot support such that the left foot support and the right foot support is passively and alternately moved in the vertical direction.
- It is preferred that the left foot support and the right foot support are configured to be rotatable about a rotation axis. The rotation axis is perpendicular to a horizontal plane.
- It is preferred that the passive exercise assisting device further comprises a rotation plate. The rotation plate has a rotation axis. The rotation axis is perpendicular to a horizontal plane. The rotation plate is rotated about the rotation axis. Both the left foot support and the right foot support are attached to the rotation plate. Consequently, the left foot support and the right foot support are rotated when the rotation plate is rotated. The rotation axis is located between the left foot support and the right foot support.
- In this case, the passive exercise assisting device is configured to give the twist motion of twisting superior limb with respect to the lower leg. Consequently, the passive exercise assisting device is capable of stimulating the various muscles such as the lower back and the lower leg, especially the adducent muscles, whereby the passive exercise exercises the user in order to develop the user's muscle more effectively.
- The vertical motion applying means is configured to give the vertical motion to the left foot support and the right foot support in order to move the left foot support and the right foot support downward as the horizontal motion applying mechanism gives the horizontal motion to the left foot support and the right foot support in order to move the left foot support and the right foot support forward from backward.
- In this case, the user's weight acts on the left foot support and the right foot support which move forward and downward. Therefore, the user is able to exercise the user's balance ability more effectively.
- It is preferred that the vertical motion applying means is configured to give the vertical motion to the left foot support in order to move the left foot support downward as the rotation motion applying mechanism moves the left foot support from the frontward tilting posture to the backward tilting posture. The vertical motion applying means is configured to give the vertical motion to the right foot support in order to move the right foot support downward as the rotation motion applying mechanism moves the right foot support from the frontward tilting posture to the backward tilting posture.
- In this case, the user is easily put the user's weight on the left foot support or the right foot support which has the backward tilting posture and which is moved downward. When the user's weight acts on the left foot support or the right foot support, the user's weight acts on the rear side of the knee, whereby the front side of the femoral area are is contracted when the user's weight acts on the left foot support or the right foot support. In this manner, the passive exercise assisting device gives the dosal flexion motion to the ankle joint effectively.
- It is preferred that the vertical motion applying means is configured to give the vertical motion to the left foot support in order to move the left foot support downward as the rotation motion applying mechanism moves the left foot support from the backward tilting posture to the frontward tilting posture. The vertical motion applying means is configured to give the vertical motion to the right foot support in order to move the right foot support downward as the rotation motion applying mechanism moves the right foot support from the backward tilting posture to the frontward tilting posture.
- In this case, the user is easily put the user's weight on the left foot support or the right foot support which has the forward tilting posture and which is moved downward. When the user's weight acts on the left foot support or the right foot support, the user's weight acts on the rear side of the knee, whereby the front side of the femoral area are is contracted when the user's weight acts on the left foot support or the right foot support. In this manner, the passive exercise assisting device gives the dosal flexion motion to the ankle joint effectively.

Consequently, the vertical motion applying means 13 is configured to hold theleft foot support 1 and theright foot support 2 such that the vertical motion applying means 13 allows theleft foot support 1 and theright foot support 2 to alternately move upward and downward like a seesaw motion - It is noted that the vertical motion applying means 13 is configured to support the
left foot support 1 and theright foot support 2 as a scale to be movable as the seesaw when the user's weight is moved to theleft foot support 1 or theright foot support 2. However, the verticalmotion applying mechanism 13 is not limited thereto. That is, it is also possible to employ the vertical motion applying means 13 which is realized by a ball or a roller. In a case where the ball or the roller acts as the fulcrum 13 a, theleft foot support 1 and theright foot support 2 is swung about the fulcrum 13 a in 360 degrees. This configuration is also employed in the following embodiments. - As mentioned above, the passive
exercise assisting device 5 of standing type being used by the user standing without bending the knee A4 is produced. In this passiveexercise assisting device 5, when the user A starts the motor while the user stands on theleft foot support 1 and theright foot support 2, theleft foot support 1 and theright foot support 2 are driven to move such that the trajectories of theleft foot support 1 and theright foot support 2 traces V-shape. Further, theleft foot support 1 and theright foot support 2 are driven to move such that theleft foot support 1 has 180 degrees out of phase with theright foot support 2. With this configuration, the passive exercise assisting device gives pseudo-walking exercise to the user. In addition, when the user trains the walking ability by the passive exercise assisting device, the passive exercise assisting device causes the weight shift of the user in the front-back direction. As a result, thebase plate 6 which holds theleft foot support 1 and theright foot support 2 is moved as the seesaw. Therefore, the user's weight is applied to either one of theleft foot support 1 or theright foot support 2 which is located lower than the other foot support. That is, when the user stands on theleft foot support 1 and theright foot support 2, the user has very precarious balance position. Then, the user tries to recover from the precarious balanced position in order to maintain balance by using the muscles of the entire body. That is, even the user's weight is slightly shifted by the passive exercise assisting device, the user's leg muscles are initiated to maintain balance by command from the brain. In this manner, the user's brain, motorius, and the balance ability is trained. In addition, agings of the brain, the motorius, and the balance ability are also trained. In addition, when theleft foot support 1 or theright foot support 2 is moved downward, the load which acts on the lower leg A3 is increased. Therefore, the user is able to train the 3-dimensional balance ability by putting the user's weight on theleft foot support 1 and theright foot support 2 certainly while the left femoral area and the right femoral area are alternately moved in the vertical direction. In this manner, the user using the passive exercise assisting device is able to train (a) the balance ability while performing the pseudo walking exercise, (b) the capacity of supporting the user's weight by only the left leg A1 or the right leg A2, and (c) the muscle of the lower leg A3 at one time. Therefore, it is possible to obtain a training assisting effect of assisting the training. In addition, the passive exercise assisting device is able to give not 2-dimensional exercise but 3-dimensional multiple exercise including planar motion in combination with a motion for maintaining the balance in the vertical direction. Therefore, the load applied to the lower leg A3 is increased. Furthermore, while the passive exercise assisting device is used by the user having a standing posture, the user has no need to bend the knee A4. Therefore, there is no possibility of applying the large load to the knee joint. Consequently, it is possible to train the muscles of the lower leg A3 while the user hurts the user's knee joint. As a result, elderly persons having a difficulty of shifting the user's weight in the front-back direction are also able to use the passive exercise assisting device easily. Therefore, the elderly persons are also able to train the walking ability by the passive exercise assisting device. -
FIG. 4 andFIG. 5 shows another embodiment. In this embodiment, the driving unit comprises the rotationmotion applying mechanism 12 in addition to the horizontal slidemotion applying mechanism 11 and the verticalmotion applying means 13. The rotationmotion applying mechanism 12 is configured to rotate each theleft foot support 1 and theright foot support 2 abouthorizontal axles 3. Thehorizontal axle 3 extends along the horizontal direction. The horizontal slidemotion applying mechanism 11 and the vertical motion applying means 13 are same as the horizontal slidemotion applying mechanism 11 and the vertical motion applying means 13 inFIG. 3 , respectively. The rotationmotion applying mechanism 12 is configured to rotate theleft foot support 1 and theright foot support 2 about the respective horizontal axles. With this configuration, the rotationmotion applying mechanism 12 gives the rotation motion of inclining the left foot support and the right foot support with the horizontal plane to theleft foot support 1 and theright foot support 2 such that each theleft foot support 1 and theright foot support 2 is movable between a frontward tilting posture and a backward tilting posture. As the foot A1 (A2) is plantarflexed to have a frontward tilting posture of having toe being located lower than the heel, the weight of the user acts on the front side of the knee, whereby the rear side of the femoral area is contracted. In contrast, as the foot A1 (A2) is dosalflexed to have a backward tilting posture (shown inFIG. 5 a) of having the heel being located lower than the toe, the weight of the user acts on the rear side of the knee, whereby the front side of the femoral area is contracted. In order to give the planarflex motion and the dorsiflex motion, as shown inFIG. 4 a, the rotationmotion applying mechanism 12 comprisesmotors 30 for theleft foot support 1 and theright foot support 2 respectively and integrally. Each themotor 30 is configured to rotate forward and backward. Each themotor 30 is configured to give rotation motion of moving the left foot support 1 (the right foot support 2) between the frontward tilting posture and the backward tilting posture. The rotation motion of the left foot support 1 (the right foot support 2) is interlocked with the V-shape motion of the left foot support 1 (the right foot support 2). For example, themotor 30 moves the left foot support 1 (the right foot support 2) to the frontward tilting posture or the backward tilting posture as the left foot support 1 (the right foot support 2) moves toward the front direction D. Consequently, the user is able to perform the planarflex motion and the dorsiflex motion in addition to the v-shape motion and the seesaw motion. - When, as shown in
FIG. 5 a, theleft foot support 1 bearing the dorsiflexed foot A1 is moved downward B1, the power is put into shin of the user such that the shin of the user withstands the motion of the foot being dorsiflexed. Consequently, the muscles of the shin are strengthened. In contrast, when, as shown inFIG. 5 b, theleft foot support 1 bearing the plantarflexed foot A1 is moved downward B1, the power is put into sura of the user such that the sura of the user withstands the motion of the foot being plantarflexed. Consequently, the muscles of the sura are strengthened. Furthermore, it is possible to reduce the shear force applied to the knee A4 in a case where the foot is dorsiflexed or plantarflexed. Therefore, there is no possibility of injury of the knee, whereby the user is able to perform the dorsiflexion exercise and the plantar flexion exercise without risk of the knee pain. In addition, when the inclination angle of the left foot support 1 (the right foot support 2) with respect to the horizontal plane is varied by themotor 30, it is possible to vary the inclination angles of theleft foot support 1 and theright foot support 2 with respect to the horizontal plane. - Furthermore, in this embodiment, when the ankle joints is moved to have a dorsiflexion condition or a plantar flexion condition, the ankle joint is dorsiflexed or plantarflexed in a direction so as not to be twisted. That is, as shown in
FIG. 4 c, each thehorizontal axles 3 are located below each one of the heels of the feet A1, A2. Therefore, the feet A1, A2 receives no force other than the force in the direction for dorsiflexing and plantarflexing. Consequently, there is no possibility of twisting the ankles, whereby the user is able to perform the dorsiflexion exercise and the plantarflexion exercise without risk of twisting the ankles. This advantage is also obtained in the embodiments other than this embodiment. -

FIG. 7 ), and the seesaw exercise B1 B2 by the vertical motion applying means 13 (shown inFIG. 6 b). Therefore, it is possible to stimulate the muscles of the lower back A6 and the lower leg A3, especially adducent muscles, whereby it is possible to strengthen the muscles more effectively. In addition, the passive twist rotation generated by therotation plate 7 with using themotor 40 makes it possible to strengthen the muscles of the lower legs A3.

When themotor 50 is started to generate frontward and backward rotation, theleft foot support 1 and theright foot support 2 are moved in the front-back direction alternately. Therefore, the passive exercise assisting device is suitable for using the pseudo ski training. -
FIG. 9 shows theleft foot support 1 and theright foot support 2 which are driven to move horizontally in the lateral direction E such that theleft foot support 1 and theright foot support 2 moves toward and away from each other. Theleft foot support 1 and theright foot support 2 are moved along aguide 62 and aguide 63 respectively. Theguide 62 and theguide 63 are configured to guide theleft foot support 1 and theright foot support 2 in the lateral direction E such that theleft foot support 1 and theright foot support 2 moves toward and away from each other. Each theleft foot support 1 and theright foot support 2 is connected to a first end of alink 60. Thelink 60 is shaped to have a rhomboid, and is configured to expand and contract in the lateral direction. Thelink 60 has a second end which is connected to apiston rod 62 of an oilhydraulic cylinder 61. When the piston rod is extended as shown inFIG. 9 b, thelink 60 extends in the lateral direction. Consequently, theleft foot support 1 and theright foot support 2 are moved away from each other. In contrast, when thepiston rod 62 is returned, thelink 60 extends in the front-back direction. Consequently, theleft foot support 1 and theright foot support 2 are moved toward each other. In this manner, theleft foot support 1 and theright foot support 2 are moved toward and away from each other in the lateral direction E. Therefore, it is suitable for the opening exercise of opening the both legs. - Each one of
FIG. 10 toFIG. 12 shows yet another embodiment. These embodiments show examples of the vertical motion applying means 14 of the vertical motion applying mechanism. Each theleft foot support 1 and theright foot support 2 has a representative point in the vertical direction B. The vertical motion applying mechanism is configured to move the representative point of theleft foot support 1 relative to the representative point of theright foot support 2. That is, the vertical motion applying means is configured to move theleft foot support 1 and theright foot support 2 in the vertical direction. The vertical motion applying means is configured to move theleft foot support 1 and theright foot support 2 in such a manner that the height of theleft foot support 1 is moved relative to the height of theright foot support 2. - The vertical motion applying means 14 in
FIG. 10 comprises the oilhydraulic cylinder 70 and thepiston rod 71. Thebase plate 6 is configured to swing about the fulcrum 13 a in such a manner that thebase plate 6 moves as a seesaw. Thebase plate 6 is provided at is one end with apiston rod 71. When thepiston rod 71 is extended, thebase plate 6 is swung about the fulcrum 13 a. An arrow B1 and an arrow B2 ofFIG. 10 show the motions of theright foot support 2 when thepiston rod 71 of the vertical motion applying means 14 is moved. In this manner, theleft foot support 1 and theright foot support 2 are passively moved as the seesaw in such a manner that theleft foot support 1 and theright foot support 2 are moved in the directions of B2 and B1, respectively. - The vertical motion applying means 14 of
FIG. 11 comprises amotor 80 and a pair ofeccentric cams eccentric cams output shaft 80 a of the motor, and are spaced from each other. When the upwardly projected dimension L1 of theeccentric cam 81 is maximized, the upwardly projected dimension L2 of theeccentric cam 82 is minimized. Theeccentric cam 81 is disposed under theleft foot support 1. Theeccentric cam 82 is disposed under theright foot support 2. When themotor 80 rotates theoutput shaft 80 a, rotation motion of each theeccentric cam 81 and theeccentric cam 82 is translated into the vertical motion of each theleft foot support 1 and theright foot support 2. Consequently, theleft foot support 1 and theright foot support 2 are passively moved in the vertical directions B1, B2 in such a manner that theleft foot support 1 and theright foot support 2 are moved as the seesaw. It should be noted that it is possible to employ twomotors FIG. 11 c in order to rotate theeccentric cams left foot support 1 and theright foot support 2 are moved individually, or are moved randomly instead of being alternately moved in the vertical direction as the seesaw. In this case, it is possible to adjust the speed, the distance, and the timing of theleft foot support 1 and theright foot support 2 in the vertical direction. Therefore, theleft foot support 1 and theright foot support 2 are randomly moved in the vertical direction. As a result, theleft foot support 1 and theright foot support 2 are moved unpredictably and passively. Consequently, it is possible to enhance the effect of the balance exercise. - The vertical motion applying means 14 of
FIG. 12 compriseslinks connection rod 92. Each thelink 90 and thelink 91 is shaped to have the rhomboid. Thelink 90 and thelink 91 are arranged in the lateral direction. Thelinks left foot support 1 and theright foot support 2, respectively. Thelink 90 is pivotally connected to thelink 91 by means of theconnection rod 92. An upper end of thelink 90 is connected to thepiston rod 96 of the oilhydraulic cylinder 95. When thepiston rod 96 is expanded in the vertical direction, thelink 90 is extended in the vertical direction while thelink 91 is shortened in the vertical direction. In contrast, when thepiston rod 96 is contracted in the vertical direction, thelink 90 is shortened in the vertical direction while thelink 91 is extended in the vertical direction. Consequently, theleft foot support 1 and theright foot support 2 are alternately moved in the vertical direction in such a manner that theleft foot support 1 and theright foot support 2 are moved as a seesaw. It should be noted that it is possible to employ individual oilhydraulic cylinders 95, and twolinks hydraulic cylinders 95 is connected to thelink 90, and the other of the oil hydraulic cylinders is connected to thelink 91 in order to move thelinks 90 91, individually. Consequently, theleft foot support 1 and theright foot support 2 are individually and randomly moved in the vertical direction. - These explanations are made on the basis of the vertical motion applying means 14 of
FIG. 10 toFIG. 12 . When the horizontal slidemotion applying mechanism 11 shown inFIG. 3 a gives the horizontal motion to theleft foot support 1 in order to move theleft foot support 1 forward D from backward C, the vertical motion applying means 14 gives the vertical motion in synchronization with the horizontal motion to theleft foot support 1 in order to move leftfoot support 1 downward B1. Therefore, the user is able to easily apply the user's weight to theleft foot support 1. Similarly, when the horizontal slidemotion applying mechanism 11 shown inFIG. 3 a gives the horizontal motion to theright foot support 2 in order to move theright foot support 2 forward D from backward C, the vertical motion applying means 14 gives the vertical motion in synchronization with the horizontal motion to theright foot support 2 in order to move theright foot support 2 downward B1. Therefore, the user is able to easily apply the user's weight to theright foot support 2. Consequently, it is possible for the user to perform the balance exercise effectively. - In addition, the explanation of the embodiment is made on the basis of the vertical
motion applying means 14. When the rotationmotion applying mechanism 12 gives the rotation motion to the left foot support 1 (the right foot support 2) in order to move the left foot support 1 (the right foot support 2) from the frontward tilting posture to the backward tilting posture shown inFIG. 4 a, the vertical motion applying means 14 moves the left foot support 1 (the right foot support 2) toward a lower direction B1 as the left foot support 1 (the right foot support 2) moves to the backward tilting posture shown inFIG. 5 a. According to this motion, it is possible for the user to apply the user's weight to the left foot support 1 (the right foot support 2) easily. Furthermore, in this case, the user's weight is applied to the rear side of the knee A4. Consequently, the front side of the femoral area is also contracted, whereby it is possible to give the dorsal flexion of the ankle joint effectively. - Further explanation of the embodiment is made on the basis of the vertical
motion applying means 14. When the rotationmotion applying mechanism 12 gives the rotation motion to the left foot support 1 (the right foot support 2) in order to move the left foot support 1 (the right foot support 2) from the backward tilting posture to the frontward tilting posture shown inFIG. 4 a, the vertical motion applying means 14 moves the left foot support 1 (the right foot support 2) toward a lower direction B1 as the left foot support 1 (the right foot support 2) moves to the frontward tilting posture tilting posture. Therefore, it is possible for the user to apply the user's weight to theleft foot support 1. Furthermore, the user's weight is applied to the front side of the knee A4. Therefore, it is possible to contract the rear side of the femoral area. As a result, it is possible for the user to plantarflex the ankle joint effectively. - Although the present invention is described with particular reference to the above illustrated embodiments, the present invention should not be limited thereto, and should be interpreted to encompass any combinations of the individual features of the embodiments.
