Here, the upper limb link 130 and the rotating member 142 is pin-coupled by the second shaft pin 132, a bearing (not shown) is provided along the portion to be coupled to the center of the second shaft pin 132 Mutual rotation is possible.

4 is a schematic diagram illustrating a state in which an interlocking structure shown in FIG. 3 is driven. Hereinafter, referring to FIG. 4, a description will be given of how the upper limb link 130, the lower link 120, and the eccentric rotation link 140 interlock when the interlock structure is driven.

As described above, one end of the lower link 120 may be pinned to the first shaft 121 so that the other end may rotate along the trajectory of the arc. One end of the upper limb link 130 is connected to the lower link 120 by the first shaft pin 131, and a predetermined position inside thereof rotates the eccentric rotary link 140 by the second shaft pin 132. It is eccentrically connected with the member 142. Therefore, the upper limb link 130 is moved along the arc trajectory in conjunction with the lower link 120, the portion connected by the first shaft pin 131, the portion connected by the second shaft pin 132 is eccentric In conjunction with the rotating member 142 of the rotary link may be moved along the circular trajectory around the rotation axis of the rotating member 142.

At this time, the eccentric rotation link 140 limits the trajectory of the portion connected to the second shaft pin 132 in the interlocking motion of the upper limb 130 to a circular orbit having a predetermined radius, resulting in the lower link 120 ) Can also limit the range of rotation. In addition, the upper limb link 130 is configured to be integrally interlocked between the lower link 120 and the eccentric rotation link 140 to move in different trajectories, the handle 133 is formed at the other end of the upper limb link 130 Moves along another trajectory.

In FIG. 4, when the rotating member 142 of the eccentric rotary link 140 rotates one counterclockwise direction, a driving state of each interlocking structure is shown for each position. Hereinafter, the handle 133 and the pedal ( 122 will be described in more detail.

As shown in FIG. 4, even when the rotating member rotates, the positions of the first shaft 121 and the second shaft 141 installed in the frame are always constant. In addition, the second shaft pin 132 connected to the upper limb 130 according to the rotation of the eccentric rotary link 140 rotates the second shaft 141 to the rotation axis.

Here, when the second shaft pin 132 is set based on the state located on the upper right side of the rotating shaft (see FIG. 4 (a)), when the rotating member 142 rotates 90 degrees counterclockwise, the second shaft pin 132 is located at the upper left of the axis of rotation (see Fig. 4 (b)). At this time, the handle 133 of the upper limb 130 is moved to the upper left side and the first shaft pin 131 connected to the lower link 120 is moved to the left direction. Therefore, the pedal 122 portion of the lower link 120 is moved downward to the left while drawing an arc trajectory close to a straight line about the first shaft 121.

Further, when the rotating member 142 is further rotated by 90 degrees, the second shaft pin 132 is located on the lower left side of the rotating shaft (see FIG. 4 (c)). At this time, the handle 133 of the upper limb 130 is moved to the lower side, the first shaft pin 131 connected to the lower link 120 is moved to the left direction. Accordingly, the pedal 122 portion of the lower link 120 is further moved downward left along the arc trajectory close to the straight line.

In addition, when the rotating member 142 is additionally rotated by 90 degrees, the second shaft pin 132 is positioned at the lower right side of the rotating shaft (see FIG. 4 (d)). At this time, the handle 133 of the upper limb link 130 is provided. ) Is moved in the right direction, and the first shaft pin 131 connected to the lower link 120 is also moved to the right upward. Therefore, the pedal 122 portion of the lower link 120 is further moved upward to the right along the call trajectory close to the straight line.

And, when the rotating member 142 is further rotated 90 degrees, the second shaft pin 132 is returned to the reference position (see Fig. 4 (a)). Thus, the handle of the upper limb is further raised to return to the reference position, and the pedal of the lower link 120 is also returned to the reference position as the pedal moves further upward along the call trajectory. At this time, when the lower link is formed sufficiently long as in the present embodiment, it can be made to reciprocate while drawing an arc trajectory close to a straight line.

As described above, the peristaltic exercise device for rehabilitation therapy according to the present invention is the upper limb link (directly or indirectly connected to the eccentric rotary link 140, when the rotary link 140 rotates about the second shaft 141). 130 and the lower link 120 is also interlocked. Here, the pedal 122 corresponding to the end of the lower link 120 is interlocked movement along the arc trajectory near the straight line with respect to the first frame 110, wherein the upper limb link 130 is the eccentric rotation link 140 And at the same time connected to the lower link 120, the pedal 122 portion of the lower link 120 during one rotation of the eccentric rotary link 140 is to perform a one-time reciprocating motion within a predetermined section range. In this case, the handle 133, which is an end of the upper limb link 130, may be interlocked while drawing an elliptical trajectory.

That is, in the rehabilitation therapy peristaltic exercise device according to the present invention, the handle 133 forms a locus of a lung curve close to an ellipse, compared to a conventional device which interlocks while forming a simple locus along a straight line or arc locus, It is possible to use more various upper body muscles. Furthermore, in the related art, a relatively large force is required at the moment when the direction of the handle 133 is reciprocated as the handle 133 reciprocates a predetermined trajectory. It is possible to improve this problem.

It is fixedly installed at both ends of the second shaft 141, and specifically, so that the insertion holes of the rotating member 142, the both ends of the second shaft 141 and the end of the second shaft 141 is inserted into a polygonal cross section, respectively. It can be configured to restrain the mutual rotation. Alternatively, as another example, the second shaft and the pair of rotating members may be integrally formed. In this case, the interlocking structure of the other side of the frame 110 may also be interlocked when the interlocking structure (rotary member, upper limb link and lower link) of one side of the frame 110 is interlocked.

Specifically, as shown in FIG. 5, the position of the connection part 143 on one side may be formed to have a phase difference of 180 degrees in the rotation direction with respect to the second shaft 141. Therefore, the interlocking structure on one side can be interlocked with the interlocking structure on the other side while maintaining the phase difference of the half cycle, such as actually walking or traveling.
