Description

Finger Exerciser {FINGER EXERCISER}

FIELD OF THE INVENTION The present invention relates to a finger exercise device, and more particularly, to a finger exercise device capable of repeatedly bending or unfolding a disabled finger and rehabilitating the finger.

In the case of stroke or Parkinson's disease, a variety of physical changes occur depending on the condition. Particularly, in the case of the above-mentioned diseases, the hand is paralyzed and the finger is shrunk.

If these hand paralysis and fingers are constantly left untreated, the muscles and joints become harder and harder to feel pain, and even if the nerves are restored, they can interfere with normal activities.

Further, in addition to the case of the above-mentioned specific diseases, there are many cases where the movement of the finger is obstructed by unexpected accident.

Therefore, in such a case, it is very important to maintain the maximum exercise capacity by promoting blood circulation and nerve communication by rehabilitating the hand that has come to be paralyzed or has a disability continuously.

A conventional technique for such a finger exercise device is disclosed in Korean Patent Laid-Open No. 10-2009-0120713.

As described above, the conventional finger playground apparatus includes a wearer for providing a mounting surface on the back of the hand, a casing provided on the mounting surface, a motor provided inside the casing, a fixing member fixed to the casing and extending to the fingertip, A plurality of operation member members extending in the longitudinal direction of the finger linked to the ends of the respective fixed member members and having joints at positions corresponding to joint regions of the fingers and contacting the respective nodes of the fingers; And a cap for fixing the end portion of the finger. Therefore, the conventional finger exercise device has a structure in which the entire finger is restrained by the fixed-end member and the plurality of operation-end members, and the finger moves jointly.

Therefore, the conventional finger exercise device receives the power from the motor, drives the joint part of the operation member, and bends or unfolds the finger in a state in which the operation member is supported on the cap.

However, in such a conventional finger athletic facility, since a fixed finger member and a plurality of operation member members are connected to each other in the form of a joint structure in one finger, the structure is complicated, the number of component parts is large and assembly is difficult, There is a high problem. Particularly, there is a problem that the connecting rod is easily broken because a force is concentrated on a connecting portion of the connecting rod connecting the plurality of operating rod members with the link member. In addition, there is a limitation in rehabilitation movement because the rotation angle of the operation member is limited and the finger can not be bent sufficiently.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 9 show a finger exercising apparatus according to an embodiment of the present invention.

As shown in these figures, the finger exercise device 1 according to an embodiment of the present invention includes a frame 10, a cradle 15, and a finger movement unit 20. [

The frame 10 supports the holder 15 and the finger movement unit 20 and is supported on the floor.

The cradle 15 is provided on the frame 10, and the palm of the user who wishes to rehabilitate is mounted. The holder 15 has a plate shape so that the palm can stably and closely contact with the palm.

The finger movement unit 20 moves a finger extending from the palm rested on the cradle 15 and moves the base 21, the link 25, the link block 31, the pair of support blocks 35a, 35b, A guide shaft 41, and a block driver 51.

Prior to explanation, the finger exercise device 1 according to the embodiment of the present invention includes four finger movement units 20 capable of moving four fingers except for the thumb, Two finger movement units 20 are shown, but since each finger movement unit 20 has the same components, one finger movement unit 20 will be described below for convenience of explanation. In the present embodiment, four finger motion units 20 are shown corresponding to detection, stop, ring finger, and hand finger, respectively. However, the present invention is not limited thereto. It is noted in advance that the finger exercise unit 20 can be provided.

The base 21 has a predetermined length and width and is fixed by the frame 10 and the fastener 13.

The link 25 has a flat bar shape, and an intermediate portion is formed inwardly and outwardly bent. At one free end of the link 25, there is provided a finger grip 27 on which a finger extended from the palm rested on the cradle 15 is caught. 9, the finger grip 27 is formed by inserting a band-like band 29 such as a band-aid or the like into the mutually locked button-shaped fastener 28, And the finger grip 27 may be a ring in which the distal end of the finger is fitted.

The link block 31 supports the other free end of the link 25 so that the finger grip 27 protrudes from the link block 31 and reciprocates linearly on the base 21.

And a pair of support blocks 35a and 35b are disposed apart from the base 21 with the link block 31 therebetween. The pair of support blocks 35a and 35b are fixed to the base 21 and serve to prevent the link block 31 from separating from the base 21. [ Hereinafter, for convenience of explanation, the support block disposed adjacent to the finger grip 27 of the pair of support blocks will be referred to as a first support block 35a and the remaining support block will be referred to as a second support block 35b.

The pair of support blocks 35a and 35b are interconnected by a guide shaft 41. [ The link block 31 is movably coupled to the guide shaft 41. The guide shaft 41 prevents the rotation of the link block 31 and guides the movement of the link block 31. The guide shaft 41 may be selectively provided. Also, the guide shaft 41 may be independently provided on the base 21 without connecting the pair of support blocks 35a and 35b as described above.

The block driving unit 51 linearly reciprocates the link block 31 along the guide shaft 41 and includes a moving block 53, a moving rod 55 and an elastic member 57.

The movable block 53 is provided to be linearly reciprocally movable between the second support block 35b and the link block 31. [ Here, the distance between the moving block 53 and the corresponding link block 31 may have a different size depending on the type of the finger held on the finger grip 27. In other words, for example, in the case of stop and hold, since the length of the finger is generally different, the distance between the mobile block 53 and the link block 31, which is interrupted, is the distance between the mobile block 53 and the link block 31, The movable block 53 and the link block 31 are arranged so as to have a relatively larger dimension than the interval between the movable block 53 and the link block 31. [

The moving rod 55 has a rod shape of a predetermined length and is parallel to the guide shaft 41 and is stationary on the moving block 53. The moving rod 55 is movably coupled to the first support block 35a and the link block 31. [

The elastic member (57) elastically supports and interconnects the link block (31) and the moving block (53). The elastic member 57 provides an elastic force such that the link block 31 and the moving block 53 are spaced apart. In the present embodiment, a coil spring is provided as the elastic member 57, and the elastic member 57 is mounted along the outer periphery of the moving rod 55. [

The block driving unit 51 of the finger exercise device 1 according to the embodiment of the present invention further includes a driving rod 61 and an actuator 63.

The driving rod 61 passes through the second support block 35b and is connected to the moving block 53. [

The actuator 63 is disposed behind the driving rod 61 to reduce the length and length of the driving rod 61. In this embodiment, a linear motor is provided. Here, instead of the linear motor, the actuator 63 may be provided with a piston or cylinder mechanism operated by hydraulic pressure or air pressure.

In addition, the finger exercise device 1 according to the embodiment of the present invention further includes a sensor unit 67 for measuring the moving distance of the link block 31. [

In the present embodiment, as the sensor unit 67, a film sensor is provided between the base 21 and the link block 31 along the movement path of the link block 31. The film sensor transmits the measured resistance value based on the depressed position to the control unit (not shown) in accordance with the movement of the link block 31, so that the movement distance of the link block 31 can be confirmed. Here, instead of the film sensor, a non-contact type position sensor may be provided as the sensor unit 67. [

Meanwhile, the finger exercise device 1 according to an embodiment of the present invention is provided with six finger exercise units 20, and the four finger exercise units 20 can be operated to perform finger movements, stop, And the other two finger motion units 20 are disposed in parallel to each other in parallel with the frame 10 so as to oppose each other with the four finger motion units 20 interposed therebetween so as to move the left hand thumb and the right thumb respectively, As shown in Fig.

Particularly, the two finger motion units 20 for moving the thumb are rotatably coupled to the frame 10 by the hinge pin 23, so that it is possible to cope with various distances between the thumb and the index finger.

In the two finger movement units 20 for moving the thumb, the first support block 35a of each finger movement unit 20 is provided with a finger movement unit 20 for detecting, stopping, Respectively.

With this configuration, a process of rehabilitating a finger using the finger exercise device 1 according to an embodiment of the present invention will be described.

Prior to description, the finger exercise device 1 according to the embodiment of the present invention has the same components as the finger movement units 20 corresponding to the thumb, index finger, stop finger, The operation of the one finger motion unit 20 will be described. However, the finger movement unit 20 for the thumb has the same components as the finger movement units 20 corresponding to the detection, the stop, the finger ring, and the hand grip, but will be described separately since the operation process of the rehabilitation movement is different.

First, a rehabilitation exercise for detecting, stopping, mediating, and holding a finger using the finger exercising apparatus 1 according to an embodiment of the present invention will be described. In this embodiment, the finger 63 is re- .

2 and 3, in a state where there is no elastic deformation of the elastic member 57, the user places the palm of the hand on the cradle 15 and at the same time, the finger is hooked on the finger grip 27.

At this time, keep your palms and fingers open. Further, the moving block 53 is fixed between the link block 31 and the second support block 35b so as not to move by an external force. In this embodiment, the moving block 53 is supported so as not to be moved by the driving rod 61 of the block driving portion 51. [

Then, when a force applied to the finger grip 27 to bend is applied, each of the nodes of the finger moves jointly while the distal end of the finger forms a rotational trajectory.

The force applied by the finger is transmitted to the link block 31 via the link 25 so that the link block 31 is moved along the guide rod 41 and the moving rod 55 to the second support block 35b, As shown in FIG.

At this time, as shown in Figs. 4 and 5, the elastic member 57 is compressed as the link block 31 moves toward the second support block 35b.

When the force applied to the finger is gradually removed after a lapse of a predetermined time, the link block 31 is pulled by the restoring force of the compressed elastic member 57 and the first supporting block 35a along the guide shaft 41 And as the bent finger is gradually unfolded, the moving block 53 returns to the original position as shown in Figs.

Thus, by repeatedly performing the operation of bending and unfolding by applying a force to each finger, the finger can be actively rehabilitated.

Next, a description will be given of rehabilitation exercises of detection, stop, ring finger, and hand using the finger exercise device 1 according to an embodiment of the present invention. In the process of rehabilitating the finger by the driving force of the actuator 63 Explain.

The user places the palm of the hand on the cradle 15 while the finger is bent at the maximum with no elastic deformation of the elastic member 57 and the finger is hooked on the finger grip 27. [

Subsequently, when the actuator 63 is driven to extend the length of the driving rod 61, the moving block 53 compresses the elastic member 57 and moves toward the link block 31 along the moving rod 55 The movable block 53 and the elastic member 57 are integrated with the link block 31 when the pressing force of the movable block 53 exceeds the compressive elastic force of the elastic member 57, And moves toward the first support block 35a along the first support block 41. [

As the link block 31 moves toward the first support block 35a, each of the nodes of the fingers held on the finger grip 27 moves jointly while the distal ends of the fingers form a rotational locus, and the fingers are unfolded.

When the actuator 63 is driven so as to reduce the length of the driving rod 61 after a lapse of a predetermined time, the elastic member 57 is compressed while the moving block 53 is separated from the link block 31, The link block 31 is moved toward the second support block 35b along the guide shaft 41 and the movable rod 55 by the tensile force of the member 57 so that the unfolded finger is gradually bent, And the link block 31 are returned to their original positions.

In this manner, the user can manually re-perform the finger by repeating the operation of bending and spreading the fingers by the driving force of the actuator 63 of the block driving unit 51. [

Meanwhile, a description will be given of a rehabilitation motion of the thumb using the finger exercise device 1 according to an embodiment of the present invention, and a process of rehabilitating the finger by the magnetic force without driving the actuator 63 will be described .

As shown in Fig. 6, in a state where there is no elastic deformation of the elastic member 57, the user places the palm of the hand on the cradle 15, and at the same time, the thumb is hooked on the finger grip 27. [

At this time, keep your palms and thumbs open. Further, the moving block 53 is fixed between the link block 31 and the second support block 35b so as not to move by an external force. In this embodiment, the moving block 53 is supported so as not to be moved by the driving rod 61 of the block driving portion 51. [

Then, when a force is applied so that the thumb gripped on the finger grip 27 is bent, the distal ends of the fingers move while the respective nodes of the thumb move jointly.

The force applied by the thumb is transmitted to the link block 31 via the link 25 so that the link block 31 is moved along the guide rod 41 and the moving rod 55 to the first support block 35a, As shown in FIG.

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

When the force applied to the thumb is gradually removed after a lapse of a predetermined time, the link block 31 is compressed by the restoring force of the tensioned elastic member 57 so that the second support block 35b And as the bent thumb is gradually unfolded, the moving block 53 returns to the original position as shown in Fig.

Thus, by repeatedly bending and unfolding the thumb with force, the thumb can be actively rehabilitated.

Next, the rehabilitation motion of the thumb using the finger exercise device 1 according to the embodiment of the present invention will be described, and the process of rehabilitating the thumb with the driving force of the actuator 63 will be described.

The user places the palm of the hand on the cradle 15 while the thumb is fully extended in the state where there is no elastic deformation of the elastic member 57 and the thumb is hooked on the finger grip 27. [

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

When the actuator 63 is driven so as to reduce the length of the driving rod 61 after a lapse of a predetermined time, the elastic member 57 is compressed while the moving block 53 is separated from the link block 31, The link block 31 moves 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 bent thumb is gradually extended, And the link block 31 are returned to their original positions.

In this way, the user can manually re-perform the thumb by manually bending and expanding the thumb by the driving force of the actuator 63 of the block driver 51. [

8, the finger exercising apparatus 1 according to an embodiment of the present invention further includes a cradle height adjusting unit 71 for adjusting the height of the cradle 15 from the base 21 .

The holder height adjustment portion 71 includes a pair of brackets 73, a holder fixture 75, a height adjustment slot 77, a height adjustment through hole 78, and a height adjustment knob 79.

The pair of brackets 73 are arranged on the frame 10 with four finger motion units 20 arranged in parallel on the frame 10 in a standing manner and the cradle 15 is movable up and down.

The holder fixture 75 has a plate shape in which both ends are bent and connects the pair of brackets 73 with each other and the holder 15 is engaged.

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

The height-adjusting through-holes 78 are formed in the holder fixing member 75 so as to communicate with the height-adjusting slots 77 of the respective brackets 73 in a circular cross-sectional shape.

The height adjusting knob 79 is inserted through the height adjusting slot 77 and the height adjusting through hole 78 to fix the pair of brackets 73 and the holder fixing member 75.

Thus, it is possible to regenerate the finger by adjusting the height of the holder 15 from the base 21 corresponding to the size and shape of various hands of the user.

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

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

The interval adjusting slot 83 is formed in the holder 15 to have a rectangular sectional shape along the moving direction of the link block 31.

The spacing adjusting through-hole 85 is formed in a circular cross-sectional shape in the seating fixture 75 so as to communicate with the interval adjusting slot 83 of the seating 15.

The gap adjusting knob 87 is inserted into the gap adjusting slot 83 and the gap adjusting through hole 85 to fix the mount 15 and the mount fixture 75.

Thus, it corresponds to the size and shape of various hands of the user, and in particular, corresponds to the length of various fingers of the user, and it is possible to regenerate the finger by adjusting the distance between the link 25 and the cradle 15. [

As described above, 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 risk of breakage during use due to no stress concentration, It is possible to perform the rehabilitation exercise in a state where it is not possible to improve the convenience.

Further, by combining the elastic member and the actuator 63 as a motion source of the finger motion unit, it is possible to automatically or manually select the finger and to re-exercise the finger.

In addition, since the position of the cradle on which the palm is mounted can be adjusted, the finger can be rehabilitated regardless of the size and shape of the finger.
