Description

Hysteresis {HANDGRIP}

More particularly, the present invention relates to a grip force machine for releasing muscles of a finger or for exercising so as to increase the strength of a finger.

Patients and athletes who can not actively control their fingers or who have an abnormality of their fingers are required to perform repetitive bending and deflating movements of the fingers to release the muscles of the fingers or to increase the strength of the fingers .

Also, finger movements are needed to comfortably release the finger muscles to modern people who are tired of excessive computer use.

To this end, various grippers for fingertip movement are commercially available. However, the commercially available gripper can easily control the strength of the gripper, so that it can be used by anyone of all ages. However, most of the grippers actively induce the wrist movement but can not induce the finger movement actively.

Therefore, there is a need for a force gauge which can be used for the purpose of raising the finger force in the patients who need rehabilitation of the fingers due to injuries to the fingers or the patients with stroke.

The prior art related to the present invention is Korean Patent No. 1319964 (published on May 31, 2013, entitled finger exercise device)

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

The present invention can strengthen the fine muscles by strengthening the finger movements, and can exercise only the thumb.

1, the present invention includes a finger band 10, a tension band 20, and a tensioning means 40, as shown in Fig.

The finger bands 10 are formed in a ring shape having a predetermined width and are worn on each of the fingers of the user. The finger bands 10 may be formed of a silicone material so as to be excellent in elasticity and not to sense a foreign body. The silicone material is nontoxic, harmless to the human body, has excellent elastic recovery ability, and is comfortable to wear.

The finger bands 10 can cover the finger joints in a relatively large area, thereby enabling finger movement while protecting the finger joints.

The tension band 20 is connected to each of the finger bands 10 and extends to the user's hand. The tension band 20 is for pulling the finger band 10 to apply tension to the finger.

Since the tension band 20 is loaded by the elasticity of the band, it can move in various directions, and can move according to the finger strength, etc., so that the finger joints are less uncomfortable and the risk of injury is low.

The tension band 20 may be made of any one of rubber, silicone, and latex having excellent elastic strength, and the load can be increased by applying two layers or a thick layer.

The tension band 20 and the finger band 10 may be formed of the same material and integrally formed. When the tension band 20 and the finger band 10 are integrally formed, the load using the tension band 20 is transmitted to the finger band 10 and the connection between the tension band 20 and the finger band 10 It can be robust.

The tension band 20 and the finger band 10 are provided one by one corresponding to the number of fingers and the tension band 20 and the finger band 10 are corresponded one to one.

The tensioning means 40 is provided on the strap 30 to be worn to wrap at least part of the user's hand and wrist to fix the tensioning band 20 and apply tension to the tensioning band 20. [

The strap 30 is for securing the tension means 40 to the user's hand or wrist. The strap 30 may be wrapped around the back of the hand and the wrist, and then the hand and the wrist may be wrapped around by the attachment and detachment means. The attaching / detaching means may be any one of a zipper, a velcro and a snap button for fastening the other side opposite to the one side of the strap 30 to each other.

The strap 30 is at least partially stretchable and can be sized according to the size of the user's hand.

The shape of the strap 30 may be a shape that wraps only the back of the hand, in addition to the shape that surrounds the back of the hand and the wrist.

The tension means 40 includes a rotation shaft 41, an operation portion 43, and a lock portion 45. [ The tension means 40 is provided with a strap 30 and a portion of the rotation shaft 41, the operation portion 43 and the lock portion 45 is exposed to the outside so that the tension adjustment degree of the tension band 20 can be adjusted by the user And can be easily identified and operated.

The rotating shaft 41 is wound around each tension band 20 and applies a tension to the tension band 20 at a rotation amount.

The rotary shaft 41 is divided into a first rotary shaft 41a on which the tension bands 20 for applying tension to the fingers other than the thumb are wound and a second rotary shaft 41b on which the tension band 20 for applying tension to the thumb is wound . When the first rotary shaft 41a is divided into the second rotary shaft 41b, only the thumb can be moved.

The operating portion 43 transmits rotational motion to the rotating shaft 41. [ The operation unit 43 may be divided into a first operation unit 43a for transmitting rotational motion to the first rotation shaft 41a and a second operation unit 43b for transmitting rotational motion to the second rotation axis 41b.

The operation portion 43 is protruded outwardly of the finger to prevent interference when the finger is moved. The shape of the operation portion 43 may be various shapes as long as the shape can be easily grasped by a user with a finger.

The first rotary shaft 41a and the second rotary shaft 41b may be integrally formed. In this case, since the first operating portion 43a provided on the first rotating shaft 41a is rotated, the second rotating shaft 41b can rotate integrally with the first rotating shaft 41a.

The lock portion 45 prevents the rotation shaft 41 from rotating in any direction in which the tension applied to the tension band 20 is released.

As shown in Figs. 2 and 3, the locking portion 45 may include a rotation wheel 47 and a locking piece 49. Fig.

The rotary wheel 47 is provided along the outer circumferential surface of a trapezoidal or triangular sawtooth which is provided on the rotary shaft 41 and integrally rotates with the rotary shaft 41 and which meets a straight line a and a straight line b. The sawtooth shape of the rotary wheel 47 ensures that the rotary wheel 47 rotates smoothly in the direction in which the tension is applied, but does not rotate arbitrarily in the opposite direction (direction in which the tension is released).

A plurality of rotation wheels (47) are provided on the rotation shaft (41). The tension band 20 is fixed to the rotary shaft 41 located in the space between the rotary wheel 47 and the rotary wheel 47 so that interference between the tension band 20 and the retaining piece 49 is prevented, 20 can be ensured.

Since the plurality of rotation wheels 47 are provided on one rotary shaft 41, the tension of the tension band adjusting the exercise intensity of each finger can be adjusted at a time by operating one or two operation portions 43 . This makes it possible to adjust the tensile strength of each tension band 20 equally, thereby enabling balanced finger movement.

This is useful for relaxing hand muscles of hand paralysis patients or for increasing finger strength.

The engaging piece 49 is sandwiched between the teeth of the rotating wheel 47 so that the rotating wheel 47 can rotate in a direction in which tension is applied. And a spring for providing a resilient force in a direction in which the engaging piece 49 is sandwiched between the teeth of the rotary wheel 47. The engaging piece 49 is sandwiched between the teeth by the tension of the spring 53 to prevent any rotation of the rotating wheel 47.

The shape of the engaging piece 49 is formed such that the surface corresponding to the straight line of the teeth is formed in a straight line, and the surface corresponding to the slanting line of the teeth is formed in an oblique line. The shape of the engaging piece 49 is such that the surface of the tooth and the engaging surface of the engaging piece do not slip relative to each other so that the rotating wheel 47 is rotated in the direction of applying the tension to the tension band 20, Ensure that the wheel does not rotate at all.

The oblique line a in the saw tooth is a portion formed to be inclined with respect to the tangential direction of the outer circumferential surface of the rotary wheel 47 and the straight line b is a portion formed perpendicularly to the tangential direction of the outer circumferential surface of the rotary wheel 47.

And a pressing portion 51 protruding upwardly from the engaging piece 49 so as to be easily pressed by the user is formed. When the pressing portion 51 is pushed toward the wrist side, the tension of the spring 53 is released. The tension release of the spring 53 induces the reverse rotation (rotation in the direction of B in Fig. 3) of the rotary wheel 47 to adjust the length of the tension band 20, thereby making it possible to adjust the strength of the tension band 20.

Hereinafter, the operation of the present invention will be described.

A method of wearing a user's hand and performing a finger exercise according to the present invention will be described.

First, the strap 30 is worn so as to cover the user's hand and the wrist to wear the user's hand. At this time, the strap 30 can be closely contacted regardless of the size of the user's hand as at least a part of the strap 30 has elasticity.

Next, the finger bands 10 are put on each finger of the user. When the finger bands 10 are put on the fingers, it is preferable that the tension bands 20 are not tensioned.

When the user applies a hand gesture machine to the user's hand through the above process, the user performs a finger movement.

In this method, the first operating portion 43a and the second operating portion 43b shown in Fig. 1 are respectively rotated to rotate the rotary shaft 41 so that the rotary wheel 47 is rotated in the direction A in Fig. Of course, it is also possible to rotate only one first operating portion 43a so that all the rotating wheels 47 provided on the rotating shaft 41 are rotated.

Rotation of the rotary wheel 47 in the A direction causes the tension band 20 to be wound around the rotary shaft 41 and the finger band 10 is pulled in the direction of the back of the hand so that the user fingers his fingers and turns the back of his hand like a bow. In this state, as shown in Fig. 4, by repeatedly performing the operation of bending the fingers, the motion of each finger is performed and the finger force is raised.

In this state, if the operating portion 43 is rotated so that the rotating wheel 47 further rotates in the direction A in Fig. 3, the strength of the tension band 20 can be further adjusted and the finger motion can be performed while further tensing the finger muscle.

At this time, even if the rotation of the operating portion 43 is stopped, the locking piece 49 interposed between the teeth of the rotating wheel 47 by the elastic force of the spring 53 prevents any rotation of the rotating wheel 47, The tension that pulls the finger band 10 is maintained.

In addition, even if the tension band 20 pulls the finger bands 10 strong, the finger bands 10 protect the finger joints, so that the finger joints are less stressed and the risk of injury is low.

On the other hand, when the tension band 20 tries to release the tension for pulling the finger band 10, the pushing portion 51 of the retaining piece 49 is pushed in the direction of the wrist so that the retaining piece 49 is rotated 47 are released.

Thereby, the rotary wheel 47 is rotated in the opposite direction and the tension in which the tension band 20 pulls the finger band 10 can be released.

The above-described hand gripper can perform finger movement with a simple operation for adjusting the length of the tension band 20 and can adjust the tension strength of each tension band 20 by operating the operation part 43 once or twice Balanced finger movement is possible.

The above-described grip force machine can prevent interference between the tension band 20 and the engagement piece 49 by connecting the tension band 20 to the rotation axis 41 positioned in the space between the rotation wheels 47, 20 can be ensured.

The above-mentioned gripper can help relax the muscles of the fingers of the patients, athletes and hand paralysis patients who can not actively control the finger joints, or can raise the strength of the fingers. It can be used to relax the finger muscles by stimulating the hard muscles of the finger.

In addition, the above-mentioned gripper can be used as a recycle for balancing the hand while stretching the entire finger by utilizing the elasticity of the finger band and the tension band, and helping recovery from injury when the finger is injured.

In addition, the above-mentioned gripper can also be used for releasing finger muscles of game addicts who have become intoxicated with computer and video games and have abnormalities in the finger muscles.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
