By such a configuration, a process of rehabilitation of the finger using the finger exercise device 1 according to an embodiment of the present invention will be described.

Prior to the description, since the finger exercise device 1 according to an embodiment of the present invention has each finger exercise unit 20 corresponding to the thumb, the index finger, the middle finger, the ring finger, and the hand, the following components are representatively described below. An operation process of one finger exercise unit 20 will be described. However, the thumb exercise unit 20 for the thumb has the same components as each finger exercise unit 20 corresponding to the index finger, middle finger, ring finger, and possession, but will be described separately because the operation process of the rehabilitation exercise is different.

First, using the finger exercise device 1 according to an embodiment of the present invention will be described for the rehabilitation exercise of the index finger, middle finger, ring finger, possession of the body, without driving the actuator 63, the finger rehabilitation exercise by the magnetic force Explain the process.

2 and 3, in the absence of elastic deformation of the elastic member 57, the user places the palm on the holder 15 and at the same time, the user places the finger on the finger grip 27.

At this time, keep your palms and fingers unfolded. In addition, the moving block 53 is fixed so as not to move by an external force between the link block 31 and the second support block 35b. In this embodiment, the moving block 53 is supported so as not to move by the drive rod 61 of the block drive unit 51.

Subsequently, when a force applied to the finger grip 27 is bent, each node of the finger moves while forming a joint trajectory while each node of the finger is articulated.

The force exerted by the finger is transmitted to the link block 31 via the link 25, so that the link block 31 is along the guide shaft 41 and the moving rod 55. Will be moved towards.

4 and 5, the elastic member 57 is compressed as the link block 31 moves toward the second support block 35b.

Then, after a certain time, if the force applied to the finger is gradually removed, the link block 31 moves the first support block 35a along the guide shaft 41 while being tensioned by the restoring force of the compressed elastic member 57. And the bent fingers are slowly extended and the moving block 53 returns to its original position as shown in FIGS. 2 and 3.

In this manner, by repeatedly applying a force to each finger and repeating the bending, the finger can be actively rehabilitated.

Next, while using the finger exercise device 1 according to an embodiment of the present invention will be described for the rehabilitation exercise of the index finger, middle finger, ring finger, the possession, the process of rehabilitation of the finger by the driving force of the actuator (63). Explain.

In the state where the finger is bent to the maximum in the state where there is no elastic deformation of the elastic member 57, the user places the palm on the holder 15 and simultaneously attaches the finger to the finger grip 27.

Subsequently, when the actuator 63 is driven to extend the drive rod 61, the movable block 53 compresses the elastic member 57 and moves along the movable rod 55 toward the link block 31. When the pressing force of the movable block 53 exceeds the compressive elastic force of the elastic member 57, the movable block 53, the elastic member 57, and the link block 31 are integrated, and the link block 31 has a guide shaft. It moves along the 41 toward the first support block 35a.

As the link block 31 moves toward the first support block 35a, each node of the finger gripped by the finger grip 27 performs joint movement, and the distal end portion of the finger moves while forming a rotational trajectory.

When the actuator 63 is driven to reduce the length of the driving rod 61 after a certain time, the compressed elastic member 57 is tensioned while the moving block 53 is spaced apart from the link block 31. The link block 31 is moved toward the second support block 35b along the guide shaft 41 and the moving rod 55 by the tensile force of the member 57, so that the extended finger gradually bends the moving block 53. And link block 31 is returned to its original position.

In this manner, by the driving force of the actuator 63 of the block driving unit 51, the user can bend and unfold the fingers to repeat the operation, it is possible to passively rehabilitate the fingers.

On the other hand, while using the finger exercise device 1 according to an embodiment of the present invention will be described for the rehabilitation of the thumb, the process of rehabilitation of the finger by the magnetic force without driving the actuator 63 will be described. .

As shown in FIG. 6, in a state in which there is no elastic deformation of the elastic member 57, the user places the palm on the holder 15 and at the same time, attaches the thumb to the finger grip 27.

At this time, the palm and the thumb to keep the state unfolded. In addition, the moving block 53 is fixed so as not to move by an external force between the link block 31 and the second support block 35b. In this embodiment, the moving block 53 is supported so as not to move by the drive rod 61 of the block drive unit 51.

Subsequently, when the thumb caught in the finger grip 27 is bent, each node of the thumb moves while forming a joint trajectory while each node of the thumb is articulated.

Then, the force exerted by the thumb is transmitted to the link block 31 via the link 25, so that the link block 31 is formed along the guide shaft 41 and the moving rod 55. Will be moved towards.

At this time, as shown in FIG. 7, the elastic member 57 is tensioned as the link block 31 moves toward the first support block 35a.

Then, after a certain period of time, if the force applied to the thumb is gradually removed, the link block 31 moves the second support block 35b along the guide shaft 41 while being compressed by the restoring force of the tensioned elastic member 57. And the bent thumb slowly unfolds, and the moving block 53 returns to its original position as shown in FIG.

In this way, by repeatedly applying a force to the thumb and bending it, the thumb can be actively rehabilitated.

Next, while using the finger exercise device 1 according to an embodiment of the present invention will be described for the rehabilitation of the thumb, the process of rehabilitation by the driving force of the actuator 63 will be described.

In a state where the thumb is fully extended in the state where there is no elastic deformation of the elastic member 57, the user places the palm on the holder 15 and simultaneously attaches the thumb to the finger grip 27.

As the link block 31 moves toward the first support block 35a, each node of the thumb caught in the finger grip 27 moves jointly, and the distal end of the thumb forms a rotational trajectory and the thumb is bent. .

When the actuator 63 is driven to reduce the length of the driving rod 61 after a certain time, the compressed elastic member 57 is tensioned while the moving block 53 is spaced apart from the link block 31. The link block 31 is moved along the guide shaft 41 and the moving rod 55 toward the second support block 35b by the tension of the member 57, so that the bent thumb is gradually extended and the moving block 53 is opened. And link block 31 is returned to its original position.

In this manner, by the user's bending force of the actuator 63 of the block driving unit 51, the user repeatedly flexes and extends the thumb so that the thumb can be manually rehabilitated.

On the other hand, the finger exercise device 1 according to an embodiment of the present invention, as shown in Figure 8, further includes a height adjustment unit 71 for adjusting the height of the holder 15 from the base 21 .

The cradle height adjusting unit 71 includes a pair of brackets 73, a cradle fixture 75, a height adjusting slot 77, a height adjusting through hole 78, and a height adjusting knob 79.

The cradle fixture 75 has a plate shape with both ends bent, and a pair of brackets 73 are interconnected to each other, and the cradle 15 is coupled thereto.

The height adjustment slot 77 is formed in a rectangular cross-sectional shape along the spaced direction of the frame 10 and the cradle 15 on the plate surface of each bracket 73 facing the cradle fixture 75.

Height-adjusting through-hole 78 is formed in the cross-sectional shape of the circular holder in the holder fixture 75 so as to communicate with the height adjustment slot 77 of each bracket (73).

The height adjustment knob 79 is coupled to the height adjustment slot 77 and the height adjustment through-hole 78 to fix the pair of brackets 73 and the cradle fixture 75.

Thus, by adjusting the height of the cradle 15 from the base 21 to correspond to the size and shape of the user's various hands, it is possible to rehabilitate the finger.

In addition, the finger movement device 1 according to an embodiment of the present invention further includes a cradle spacing adjusting unit 81 for adjusting a spacing between the link 25 and the cradle 15.

The cradle spacing adjusting unit 81 includes a spacing adjusting slot 83, a spacing adjusting through hole 85, and a spacing adjusting knob 87.

The gap adjusting slot 83 is formed through the cradle 15 in a rectangular cross-sectional shape along the moving direction of the link block 31.

The gap adjusting through hole 85 is formed to penetrate in a circular cross section in the holder fixture 75 so as to communicate with the gap adjusting slot 83 of the holder 15.

The gap adjusting knob 87 is coupled to the gap adjusting slot 83 and the gap adjusting through-hole 85 to fix the holder 15 and the holder fixture 75.

In this way, the size and shape of the user's various hands, in particular corresponding to the length of the user's various fingers, by adjusting the distance between the link 25 and the cradle 15, it is possible to rehabilitate the finger.

Thus, according to the present invention, by modularizing the finger movement unit for directly moving the finger, the structure is simple, easy to assemble, there is no concentration of stress, there is no risk of damage during use, restrain each node of the finger Rehabilitation exercises can be performed without doing so, and convenience can be improved.

In addition, by implementing the combination of the elastic member and the actuator 63 as a motion source of the finger exercise unit, it is possible to automatically or manually select the rehabilitation movement of the finger.
