3 is a view illustrating the bending operation of the first and middle nodes of the finger according to the present invention is a view showing an example of refraction of the first and middle nodes of the finger by the DCP unit and the PIP unit. Hereinafter, a bending operation according to the present invention will be described with reference to FIG. 3.

First, when the motor 102 rotates in the forward direction, that is clockwise, the prime move gear 103 also rotates in the forward direction. When the prime move gear 103 rotates in the forward direction, the connecting gear 104 rotates in the reverse direction, and thus the output gear 105 rotates in the forward direction. At this time, since the rotational speed of the motive gear 103 is high, it is preferable to use a connection gear 104 and the output gear 105 having a diameter larger than the diameter of the motive gear 103 to reduce the speed. As the output gear 105 rotates in the forward direction, the MCP link 1 210 rotates isotropically in a clockwise direction, that is, in a downward direction. As the shaft of the output gear 105 rotates, the MCP link 2 220 exerts a downward force. By this force, the MCP block 240 refracts downward by applying a force to the first node of the finger. At this time, as the MCP block 240 moves downward, the phase between the input pulley 250 and the MCP link 2 220 is changed so that the input pulley 250 rotates in the reverse direction. As the input pulley 250 rotates in the reverse direction, the pulley belt 255 rotates in the reverse direction, and the double gear pulley 260 also rotates in the reverse direction. As the dual gear pulley 260 rotates in the reverse direction, the MCP output gear 270 meshed with the second gear of the dual gear pulley 260 rotates in the forward direction. Therefore, the PIP link 1 310, which is axially coupled to the MCP output gear 270, rotates in an isometric axis. As the PIP link 1 310 rotates in an isometric axis, the PIP link 2 340 refracts by applying a force to the PIP block 370. Although not shown in FIG. 3, the DIP unit 400 also changes the phase between the PIP input gear 350 and the PIP link 2 340 as the PIP block 370 is refracted, similarly to the PIP unit 300. The gear 350 rotates in the reverse direction. When the PIP input gear 350 rotates in the reverse direction, the PIP output gear 360 rotates in the forward direction to rotate the DIP link 1 420 in an isometric axis. At this time, the PIP output gear 360 increases the rotational speed of the PIP input gear 350 having a low rotational speed. According to the body structure, the refractive angle of the first node of the finger by the MCP unit 200 is about 90 degrees, the refractive angle of the middle node is about 120 degrees, and the refractive angle of the end node is preferably set to about 90 degrees.

4 is a view for explaining a method of adjusting the position of the MCP block according to the length of the first node of the finger according to the present invention.

Referring to FIG. 4, when the fixing hole 222 is placed on the left side of the arc hole 231 and fixed as shown in FIG. 4A, the first length part 221 and the second length part 230 are straight. As a result, the distance between the metacarpal joint rotation virtual shaft 21 and the end of the MCP block 240 is, for example, 51.5 mm. On the contrary, when the fixing hole 222 is placed on the right side of the arc hole 231 and then fixed with a screw, the first length part 221 and the second length part 230 are oriented substantially vertically, thereby the MCP block 240. The heavy joint joint is pulled by the rotating virtual shaft 21 to 45.5 mm. That is, it can be seen that the distance from the metacarpal joint rotation virtual shaft 21 to the end of the MCP block 240 is shortened. In conclusion, the position of the MCP block 240 to be fixed to the first node of the finger according to the position of the fixing hole 222 in the arc hole 231 can be adjusted. This is because the length of a finger is different for each person, and if the length of a finger is different, the length of a node is also different. For example, in the case where the length of the first node is long, the fixing hole 222 is placed on the left side of the arc hole 231, and in the case of the person who is short in the first node, the fixing hole 222 is on the right side. Let go. As such, by adjusting the position of the MCP block 240 that deflects and extends the first node, the overall length of the finger exercise device is also shortened.

5 is a view showing a method of controlling the angle of refraction by adjusting the length of the link 1 of the PIP unit according to the present invention, Figure 5a is a PIP link 1 310 and PIP link 2 ( When the distance between the hinge axis of the 340 is A, it shows the angle required to bend the middle node of the finger 90 degrees, Figure 5b is a PIP link 1 310 and the MCP link 2 ( In the case where the distance between the hinge axes of the head 340 is short B (A> B), this indicates the angle required to bend the middle node of the finger by 90 degrees. In the following description, the refractive angle of the middle node of the finger is 120 degrees in physical terms, but for the convenience of explanation, the refractive angle will be described with an example of 90 degrees.

As shown in (a) of FIG. 5A, the distance between the rotation axis of the MCP output gear 270 and the hinge axis is A, and the hinge axis and the proximal articulation rotation virtual shaft 22 are formed around the rotation axis of the MCP output gear 270 as a center point. When the angle is 166 degrees, as shown in FIG. 5A (b), the PIP link 1 310 must be rotated 91 degrees to bend the first node of the finger 90 degrees.

On the contrary, as shown in (b) of FIG. 5B, the distance between the rotation axis and the hinge axis of the MCP output gear 270 is adjusted to be shorter than A, and the hinge axis and the proximal joint rotation are rotated around the rotation axis of the MCP output gear 270. When the angle formed by the virtual axis 22 is 182 degrees, the PIP link 1 310 should be rotated 108 degrees in order to obtain a refractive angle of 90 degrees. In other words, when the length of the PIP link 1 310 is shortened as shown in FIG. 5B and the rotation angle as shown in FIG. 5A is given, that is, the PIP link 1 310 is not rotated by 108 degrees, as shown in FIG. 5A. Rotating the PIP link 1 310 only 91 degrees causes the middle node of the finger to be refracted only 73 degrees. In conclusion, the refraction angle of each node can be adjusted by adjusting the length of the link 1 of each of the MCP unit 200, the PIP unit 300, and the DIP unit 400.

On the other hand, the present invention is not limited to the above-described typical preferred embodiment, but can be carried out in various ways without departing from the gist of the present invention, various modifications, alterations, substitutions or additions in the art Anyone who has this can easily understand it. If such improvement, change, substitution or addition is carried out within the scope of the appended claims, the technical spirit should also be regarded as belonging to the present invention.
