EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated based on an accompanying drawing.

The passive exercise assisting device 5 of the present invention includes a left foot support 1, a right foot support 2, and a drive unit. The left foot support 1 is shaped to support the user's left foot A1. The right foot support 2 is shaped to support the user's right foot A2. The drive unit is configured to impart movement to the left foot support 1 and the right foot support 2 such that the left foot support 1 and the right foot support 2 interlock with each other. The drive unit includes at least one of a horizontal motion imparting mechanism and a rotational motion imparting mechanism. The rotational motion applying mechanism is configured to impart a rotational motion for rotating the left foot support 1 and the right foot support 2 around the horizontal axis 3 to each of the left foot support 1 and the right foot support 2. The horizontal axis 3 extends along the horizontal plane. Moreover, a drive unit contains a vertical motion provision mechanism. The up-and-down motion applying mechanism performs the up-and-down motion of moving the left foot support 1 and the right foot support 2 in the up-down direction B to the left foot support 1 and the right foot support 2 in synchronization with the horizontal motion or the rotational motion. It is configured to grant.

1 to 3 show one embodiment of a passive exercise assisting device of standing. 1 is a schematic view of the left foot support 1 and the right foot support 2 which are individually movable in the vertical direction. 2 is a schematic view of the left foot support 1, the right foot support 2, and the vertical motion applying means 13 of the vertical motion applying mechanism. The vertical movement imparting means 13 is configured to move the left foot support 1 and the right foot support 2 separately in the up and down direction. 3 is a schematic view of a standing passive exercise assisting device which also includes a horizontal slide motion applying mechanism 11 and a vertical motion applying means 13.

The horizontal slide motion giving mechanism 11 shown in FIG. 3 is equivalent to the horizontal motion giving mechanism. The horizontal slide motion applying mechanism 11 moves the left foot support 1 and the right foot support 2 forward and backward and left and right directions so that the combination of the trajectory of the left foot support 1 and the trajectory of the right foot support 2 draws a V shape. It is also configured to move. As a result, the horizontal slide exercise applying mechanism 11 stretches the leg muscles of the user. The horizontal slide motion applying mechanism 11 includes a base plate 6, a rail 8 on the left side and a rail 8 on the right side. The rail 8 on the left side and the rail 8 on the right side are fixed to the upper surface of the base plate 6. The rail 8 on the left side has a longitudinal direction Y1. The rail 8 on the right side has a longitudinal direction Y2. When the left rail 8 and the right rail 8 extend forward, the left rail 8 and the right rail 8 extend in the left direction and the right direction, respectively. Therefore, when the rail 8 on the left side and the rail 8 on the right side extend toward the front, the longitudinal direction Y1 is extended in the longitudinal direction so that the rail 8 on the left side and the rail 8 on the right side extend away from each other. Y2) and intersect at a predetermined angle. When the motor 21 is started, the motor 21 rotates the worm wheel 9 to reciprocate the truck 20 on the left side along the longitudinal direction Y1 of the rail 8 on the left side and also to the right side. The truck 20 is reciprocated along the longitudinal direction Y2 of the rail 8 on the right side. When the truck 20 on the left side and the truck 20 on the right side are moved back, the left foot support 1 and the right foot support 2 which hold the left truck 20 and the right truck 20 respectively are rails on the left side. It reciprocates along the longitudinal direction Y1 and the longitudinal direction Y2 of (8) and the right rail 8.

On the other hand, the vertical motion imparting means 13 shown in FIG. 3 (b) supports the center of the lower surface of the base plate 6 to support the base plate 6 like a scale and to adjust the lower surface of the base plate 6. The center serves as a fulcrum 13a. As a result, the vertical movement applying means 13 is configured to hold the left foot support 1 and the right foot support 2 so that the left foot support 1 and the right foot support 2 can alternately move up and down like a seesaw movement. do.

It should be noted that the up-and-down movement imparting means 13 moves the left foot support 1 and the right foot support 2 like a scale that can move like a seesaw when the user's weight is moved to the left foot support 1 or the right foot support 2. It is configured to support. In other words, it is also possible to employ a vertical motion imparting means 13 embodied as a ball or roller. When the ball or roller serves as the pedestal 13a, the left foot support 1 and the right foot support 2 are swung 360 degrees with respect to the pedestal 13a. This configuration may also be employed in the following embodiments.

As described above, the standing passive passive exercise assisting apparatus 5 used by the user standing without bending the knee A4 is manufactured. In this passive exercise assisting device 5, when the user A drives the motor while standing on the left foot support 1 and the right foot support 2, the left foot support 1 and the right foot support 2 are driven to the left foot. The trajectories of the support 1 and the right foot support 2 move to draw a V shape. In addition, the left foot support 1 and the right foot support 2 are driven so that the left foot support 1 moves with the right foot support 2 with a phase difference of 180 degrees. By this arrangement, the passive exercise assisting device can provide a 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 moves the user's weight in the front-back direction. As a result, the base plate 6 holding the left foot support 1 and the right foot support 2 is moved like a seesaw. Thus, the user's weight is applied to either the left foot support 1 or the right foot support 2 positioned lower than the other foot support. That is, when the user stands on the left foot support 1 and the right foot support 2, the user is in a very unstable balance state. The user then tries to recover from an unstable balance state to maintain balance using the muscles of the whole body. That is, even if the weight of the user is slightly moved by the passive exercise assisting device, the leg muscle of the user initiates an operation for maintaining balance by the command from the brain. As such, the user's brain, motorius, and balance skills are trained. In addition, anti-aging of the brain, motor neuron, and balance ability is also trained. In addition, when the left foot support 1 or the right foot support 2 is moved downward, the load acting on the lower leg A3 is increased. Therefore, the user can train the three-dimensional balance ability by placing the weight on the left foot support 1 and the right foot support 2 while alternately moving the left thigh and the right thigh. As such, a user using a passive exercise assisting device may be capable of (a) balancing ability while performing pseudo walking exercise, (b) ability to support weight only with left foot A1 or right foot A2, and (c) lower limb ( You can train the strength of A3) at once. Accordingly, the passive exercise assisting device can provide a three-dimensional complex motion including not only two-dimensional motion but also planar motion in combination with motion maintaining balance in the vertical direction. Therefore, the load on the lower surface A3 is increased. The passive exercise assisting device is used by the user in a standing posture, but the user does not need to bend the knee A4. Therefore, there is no possibility that a large load is applied to the knee joint. Therefore, the user can train the muscles of the lower limb without injuring the knee joint. As a result, even the elderly who are difficult to move their weight back and forth can easily use the passive exercise assisting device. Therefore, elderly people can also train walking ability with a passive exercise assistive device.

4A-4C and FIGS. 5A-5B show another embodiment. In the present embodiment, the drive unit includes a rotational motion imparting mechanism 12 in addition to the horizontal slide motion imparting mechanism 11 and the vertical motion imparting means 13. This rotary motion applying mechanism 12 is configured to rotate each of the left foot support 1 and the right foot support 2 around the horizontal axis 3. The horizontal axis 3 extends along the horizontal direction. The horizontal slide motion applying mechanism 11 and the vertical motion applying means 13 are the same as the horizontal slide motion applying mechanism 11 and the vertical motion applying means 13 in FIG. 3, respectively. The rotary motion imparting mechanism 12 is configured to rotate the left foot support 1 and the right foot support 2 about each horizontal axis 3. By this structure, the rotational motion provision mechanism 12 allows the left foot support 1 and the right foot support 2 to move to the forward inclination and backward inclination positions, respectively, so that the left foot support 1 and the right foot support 2 can be moved. ) Can provide a rotational movement of tilting the left foot support 1 and the right foot support 2 together with the horizontal plane. When the feet A1 and A2 are flexed and in a forward tilted position where the toes are positioned lower than the heel, the user's load acts on the front of the knee, causing the back of the thigh to contract. Conversely, when the foot A1 (A2) is flexed (shown in FIG. 5A) so that the heel is in the backward tilting position where it is positioned lower than the toes, the user's load acts on the back of the knee, so that the front of the thigh contracts. do. To impart low buckling motion and back flexing motion, as shown in FIG. 4A, the rotary motion imparting mechanism 12 includes a motor 30 integrally with respect to each of the left foot support 1 and the right foot support 2. Each motor 30 is configured to rotate forward and backward. Each motor 30 is configured to perform a rotational movement for moving the left foot support 1 (right foot support 2) between a forward tilting position and a backward tilting position. The rotational movement of the left foot support 1 (right foot support 2) is linked with the V-shaped motion of the left foot support 1 (right foot support 2). For example, the motor 30 is in a position in which the left foot support 1 (right foot support 2) moves forward D, or the left foot support 1 (right foot support 2) is inclined forward or backward. Move to a tilted position. As a result, the user can perform the low buckling exercise and the back flexion exercise in addition to the V-shaped exercise and the seesaw exercise.

As shown in FIG. 5A, when the left foot support 1 supporting the backed foot A1 is moved downward B1, force is entered into the user's shin to endure the movement of the foot where the user's shin is excavated. As a result, the strength of the knee is strengthened. Meanwhile, as shown in FIG. 5B, when the left foot support 1 supporting the flexed foot A1 moves downward (B1), a force enters the calf of the user and endures the movement of the calf of the user's calf. Serve As a result, the calf's strength is strengthened. In addition, it is possible to reduce the shear force applied to the knee A4 when the foot is bent or bottomed. Therefore, there is no possibility of injuring the knee, so that it is possible to perform the exercise of back and bottom flexion without the risk of knee pain. In addition, when the inclination angle of the left foot support 1 (right foot support 2) with respect to the horizontal plane is changed by the motor 30, the inclination angle of the left foot support 1 and the right foot support 2 with respect to the horizontal plane is changed. It is possible to.

In addition, in the present embodiment, when the knee joint is moved and becomes in the refraction state or the low refraction state, the refraction or refraction is performed in the untwisted direction. That is, as shown in Fig. 4C, each horizontal axis 3 is located under each of the heel of the feet A1 and A2. Therefore, the feet A1 and A2 are not subjected to force other than the force in the direction of refraction and low buckling. As a result, there is no possibility of twisting the ankle, so that the user can exercise the back and bottom flexion without the risk of twisting the ankle. This advantage can also be obtained in embodiments other than the present embodiment.

The eccentric cam 81 is disposed below the left foot support 1. The eccentric cam 82 is disposed under the right foot support 2. When the motor 80 rotates the output shaft 80a, the rotational motion of each of the eccentric cam 81 and the eccentric cam 82 is converted to the vertical motion of each of the left foot support 1 and the right foot support 2. As a result, the left foot support 1 and the right foot support 2 are passively moved in the up and down directions B1 and B2, so that the left foot support 1 and the right foot support 2 are moved like a seesaw. Note that it is also possible to rotate the eccentric cam 81 and the eccentric cam 82 separately by employing the two motors 80A and 80B shown in Fig. 11C. As a result, the left foot support 1 and the right foot support 2 are moved separately or irregularly instead of alternately moving up and down like a seesaw. In this case, it is possible to adjust the speed, distance, and timing of the left foot support 1 and the right foot support 2 in the vertical direction. Accordingly, the left foot support 1 and the right foot support 2 are irregularly moved in the vertical direction. As a result, the left foot support 1 and the right foot support 2 are moved unpredictably and passively. Therefore, the effect of balance exercise can be increased.

The vertical motion imparting means 14 of FIGS. 12A and 12B (hereinafter referred to as FIG. 12) includes links 90 and 91 and a connection rod 92. Each of the link 90 and the link 91 is in the form of a convenience. The link 90 and the link 91 are arrange | positioned in the horizontal direction. The links 90 and 91 are configured to expand and contract in the vertical direction B, and are disposed below the left foot support 1 and the right foot support 2, respectively. The link 90 is pivotally connected to the link 91 by the connecting rod 92. The upper end of the link 90 is connected to the piston rod 96 of the hydraulic cylinder 95. When the piston rod 96 is extended in the vertical direction, the link 90 is extended in the vertical direction and the link 91 is reduced in the vertical direction. On the other hand, when the piston rod 96 is contracted in the up and down direction, the link 90 is reduced in the up and down direction and the link 91 is extended in the up and down direction. As a result, the left foot support 1 and the right foot support 2 are alternately moved up and down so that the left foot support 1 and the right foot support 2 are moved like a seesaw. Note that it is also possible to employ separate hydraulic cylinders 95 and two links 90, 91 that are spaced from each other. One of the hydraulic cylinders 95 is connected to the link 90, and the other of the hydraulic cylinders 95 is connected to the link 91 to move the links 90, 91 separately. As a result, the left foot support 1 and the right foot support 2 are individually moved in the up and down direction irregularly.

These explanations are made based on the vertical motion applying means 14 of Figs. When the horizontal slide movement applying mechanism 11 shown in FIG. 3A moves the left foot support 1 horizontally to move the left foot support 1 forward from the rear C, the vertical movement imparting means 14 moves to the horizontal motion. In synchronization, the left foot support 1 is moved up and down to move the left foot support 1 downward B1. Thus, the user can easily put the weight on the left foot support (1). Similarly, when the horizontal slide movement applying mechanism 11 shown in FIG. 3A horizontally moves the right foot support 2 to move the right foot support 2 forward from the rear C, the vertical movement imparting means 14 The right foot support 2 is moved up and down in synchronization with the horizontal motion to move the right foot support 2 downward B1. Thus, the user can easily put the weight on the right foot support (2). As a result, the user can effectively perform the balance exercise.

 Moreover, an Example is demonstrated based on the vertical movement provision means 14. The rotational motion applying mechanism 12 shown in FIG. 4A rotates the left foot support 1 (right foot support 2), and tilts the left foot support 1 (right foot support 2) backward in an inclined forward position. When the left foot support 1 (right foot support 2) moves to the inclined backward position shown in Fig. 5A, the upper and lower motion granting means 14 moves to the losing position, and the right foot support 2 )] Is moved downward (B1). According to this exercise, the user can easily put the weight on the left foot support 1 (right foot support 2). In this case, the weight of the user is carried on the back of the knee A4. As a result, the anterior femoral part is also contracted, and it is possible to effectively deflate the knee joint.

In addition, an Example is demonstrated based on the up-and-down movement provision means 14. The rotational motion applying mechanism 12 shown in FIG. 4A rotates the left foot support 1 (right foot support 2), and tilts the left foot support 1 (right foot support 2) forward in an inclined backward position. When the left foot support 1 (the right foot support 2) moves to the inclined forward position, the vertical movement imparting means 14 moves downward in the losing posture. Move on to (B1). Therefore, the user can easily put the weight on the left foot support 1. In addition, the weight of the user is carried on the front of the knee (A4). Therefore, it is possible to contract the back of the thigh. As a result, it is possible for the user to effectively flex the knee joint.

Although the present invention has been described with reference to the illustrated embodiments above, the present invention is not limited thereto and should be construed to include any combination of individual features of the embodiments.
