Abstract
The invention discloses a basketball exerciser, in particular a finger root joint limiter used for fixing a shooting form, which is used for correcting the shooting form. The finger root joint limiter comprises a ring (1) in a size suitable for the root of a finger and a barrier strip (2), wherein the ring (1) and the barrier strip (2) are fixedly connected together; and when in use, the barrier strip (2) points to a palm and the barrier strip (2) is at least longer than a finger root joint. When a user shoots a basket, due to the blocking of the palm, the tail end of the barrier strip (2) cannot move to the palm, so that the joint of a ring finger cannot be bent and cannot tip a basketball to further force a forefinger and a middle finger to tip the basketball. The finger root joint limiter can be used in basketball shooting training and in matches and also can be used for seeking for basketball shooting feelings before the matches.
Description
Technical field
The present invention relates to a kind of basketball movement apparatus, especially a kind of finger root joint limiter that is used for fixing the posture of shooting.
Background technology
In basketball movement, the one-harld set shot of standard, jump shot, in the act of shooting such as lay up, the finger of having an effect of stirring ball when selling is generally middle finger and forefinger.Because when one-harld set shot or jump shot, the palm of the hand forward, the radius of forearm and ulna are in crossing state, the trend that radius and ulna is rotated to parastate is arranged under the effect of pullling of muscle, forearm has the trend or the custom of getting back to the position under the natural relaxation state in other words, the forearm that causes just displaying just turns clockwise, and causes the third finger just to have an effect and dials ball; What have exceeds the proper limits in righting a wrong, and the situation that thumb is stirred basketball occurs; What have wants to use one-hand shot, but with the hands shooting habitually when selling has been stirred basketball with thumb; A lot of people can accomplish when oneself practises shooting with forefinger and middle finger shooting, but when playing, the still uncontrollable third finger or the thumb of firmly using stirred basketball; That have even still do not change the custom of stirring basketball by a large amount of training with nameless.These all can cause shooting to depart from objectives when selling, and do not have and tremble wrist or tremble the wrist deficiency, and basketball does not have reverse rotation and parabola is not high.Will ask for feel before the somebody plays basketball, wherein some reason is exactly to find forefinger and middle finger to stir the sensation of basketball.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of people of impelling stir basketball with forefinger and middle finger when shooting utensil.
For solving the problems of the technologies described above, finger root joint limiter of the present invention comprises finger ring and the catch that is fit to the finger root size, finger ring and catch are fixed together, and when being in user mode, catch points to the centre of the palm and catch length surpasses finger heel joint at least.
During use, catch is pointed to the centre of the palm, finger ring is worn over nameless root.During shooting, nameless root one is exerted oneself downwards a little, will drive catch upwards, since palm stop that the catch end can not make progress again, finger ring also just can not be downward, thereby make that nameless joint can not be crooked, thus basketball can not firmly be stirred, thus force forefinger and middle finger to stir basketball.Same, finger ring is worn over can prevents on the thumb that thumb from stirring basketball.
As a kind of optimal way of the present invention, finger ring and catch are all thinner, narrow, general finger ring and catch thickness are less than 1.5mm, the catch width is less than 10mm, the finger ring width is less than the distance of finger root dactylus thickness and finger and palm junction, so as not to influence basketball in palm the position and generous finger ring and catch make palm catch basketball also uncomfortable.
As a kind of improvement of the present invention, the catch end is wideer than catch heel and middle part, to increase the contact area of palm and catch, reduces the pressure of catch to palm, uses more comfortable.
As a further improvement on the present invention, the catch end is an arc, to increase the contact area of palm and catch, in order to avoid sharp-pointed corner scratches palm.And reduced the pressure of catch equally, used more comfortable palm.
As a further improvement on the present invention, the catch end is enclosed with the protective sleeve that soft cloth, sponge, rubber, plastics etc. are made, and to increase the contact area of palm and catch, reduces the pressure of catch to palm, uses more comfortable
As another kind of improvement the of the present invention, be connected with on the catch and can be fixedly coupled rope or connecting band by the thorny palm, so that catch is close to the centre of the palm motion time, avoid accident to pull catch and cause to palm and other athletic injuries.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is done further detailed explanation:
Fig. 1 is the front view that finger root joint limiter of the present invention can not the thorny palm be fixedly coupled rope or connecting band.
Fig. 2 is that finger root joint limiter of the present invention has the front view that can the thorny palm be fixedly coupled rope or connecting band.
The specific embodiment
Be made up of with catch 2 finger ring 1 that is fit to the finger root size finger root joint limiter shown in Figure 1, finger ring 1 is fixed together with catch 2, and when being in user mode, catch 2 points to the centre of the palm and catch 2 length surpass finger heel joint at least.Finger ring 1 and catch 2 are all thinner, narrow, general finger ring 1 and catch 2 thickness are less than 1.5mm, catch 2 width are less than 10mm, finger ring 1 width is less than the distance of finger root dactylus thickness and finger and palm junction, so as not to influence basketball in palm the position and generous finger ring 1 make palm catch basketball also uncomfortable with catch 2.Catch 2 is terminal wideer with root than its middle part, and catch 2 ends are arc, in order to avoid sharp-pointed corner scratches palm.Its catch 2 ends are enclosed with protective sleeve 3, and protective sleeve 3 usefulness can be made with soft cloth, sponge, rubber, plastic or other material, have so further avoided the catch 2 terminal palms that scratch, and use also more comfortable.Finger ring 1 and catch 2 can be that an integral body also can be by being welded together, and material can be used aluminium alloy, steel, iron, plastics or bamboo wood.This finger-joint limiter is in order to limit nameless root joint or thumb root joint.
Fig. 2 shows second kind of finger root joint limiter, and what be different from first kind of finger root joint limiter is that its catch 2 ends are connected with and can be fixedly coupled rope or connecting band 4 by the thorny palm.Can beat the fixing mode such as fishing without hook that also can on connecting band 4, be provided with of slip-knot and fix catch 2 ends.When making motion like this, catch 2 is close to the centre of the palm, avoids accident to pull catch 2 and cause palm and other athletic injuries.
The present invention is not limited to the above specific embodiment; as long as link together with finger ring 1 and catch 2; when being in user mode; catch 2 points to the centre of the palm and catch 2 length surpass finger heel joint at least; no matter whether its catch 2 ends amplify, whether be arc, whether wrap up protective sleeve 4; perhaps be used for fixing other finger root joints, all drop among the protection of the present invention.
