Description

Involved in the present invention the is end cover of a kind of tennis and other similar ball racket handles and the racket that this end cover is housed, this end cover is fitted in the free end of this handle, or in a tubular form the time, then can constitute the capping of this handle free end at this handle.

We know, the hold of tennis racket, be that the angle position of handle in tennis or other similar ball sporter hands depends on that the sporter prepares the kind of the ball that will beat, as: forehand, low linner ball (chop or lift), the low handball (chop or lift) of redressing, service and slam-shot.

Particularly for a new hand, learn operational phase at first at him, no matter the cross section of racket handle is anistree shape, still be rule or irregularly shaped, before he played each ball, the location was very difficult, thereby also just was difficult to adopt correct racket hold.

Purpose of the present invention is exactly can be easy to adopt the location way of correct racket hold to eliminate above-mentioned shortcoming by providing a kind of.

For this reason, end cover involved in the present invention is made of one flat part at least, its octagonal periphery is consistent with the octagonal periphery in racket handle free end cross section basically, this flat part has two mutual differences at least, adjacent delta, its summit is just in time dropped on the longitudinal axis of described handle, delta is made of an adjacent side in the flat part octagonal periphery beyond this summit, this flat part is the free end that in accordance with regulations angle position is fixed on handle, and the division of delta make this handle with respect to the sporter on hand the angle of a certain fixed position be correct.

Then, when playing a ball with a kind of play, as long as the sportsman has been referred to its position that should hold of holding bat, this position is exactly that its a certain on hand fixed point of holding bat should correspond to some districts in a plurality of trigonums, so just can make the sporter can adopt correct grip rapidly and smoothly.

For example, if a certain fixed point of the hand of being considered is a hypothenar, the end cover then is fixed on the free end of handle in the following manner, even each delta of distinguishing is arranged in order corresponding to the median surface of racket screen frame (promptly clapping net) mutually, like this, when beating a certain specific ball, the hypothenar of sporter's hand just should cover on the handle and the corresponding position of a certain delta.

Be not difficult to find out that this end cover provides great convenience for initial the trial with the racket player.

Flat part can only constitute it by a kind of automatic adhesive film can stick on the handle free end automatically, perhaps constitute by a rigid thin slice, this thin slice can be fixed on the free end of handle with any suitable mode, and when handle in a tubular form the time, it can also constitute the capping of handle.

According to the simple and easy embodiment of invention, each delta of end cover all has the color of oneself, to show difference.

When the end cover of racket handle is made of the hoop cover that can be inserted in the handle free end, that is to say, end cover flat pieces has had a cylindricality lasso limit, this lasso free-ended periphery of handle of can fitting tightly, each delta under the end cover flat part is all stretched by the outer surface of column region along its lasso like this, distinguishing characteristic on the column region, for example color or other differentiation way be with above-mentioned trigonum on the same.

When handle when itself and racket screen frame connecting place have a collar (it constitutes by being close to the lasso that closes the handle periphery), some column region can be set on the outer surface of this collar, arrange according to the direction of extension of each column region of end cover lasso in these districts, and And has identical separator with the latter.

Another characteristics of the present invention are, in order to make the sporter rotate 180 ° of its racket handles, and don't the advantage of forfeiture subregion mark, therefore, put at end and to be provided with two groups of deltas and garden column region, sometimes also be provided with two groups of column region on the collar, second group of delta and column region are to be that benchmark and first group of delta and column region are arranged symmetrically with the handle axis.

Then invention is elaborated by embodiment with reference to accompanying drawing ， And below, embodiment illustrates the enforcement pattern of this end cover and its occupation mode, but this embodiment is nonrestrictive.

Fig. 1 is the perspective view that the tennis racket handle free end of this end cover is housed;

Fig. 2, Fig. 3 and Fig. 4 are the rearview of tennis racket, and this tennis racket is held by tennis person's right hand, illustrate three kinds of different racket holds, are respectively: forehand, service, normal backhand or slam-shot and lift backhand;

Fig. 5 is the another kind of embodiment's of the present invention, and the perspective view of the racket handle free end of end cover is housed;

Fig. 6 is similar to Fig. 2, illustrates a kind of occupation mode of racket, has replenished the diagramatic content of Fig. 2 to Fig. 4;

Fig. 7 is similar to Fig. 1, expresses the another kind of embodiment of end cover of the present invention.

As shown in Figure 1, end cover of the present invention is made of the flat part that is film, thin slice or en plaque, and its periphery adapts with the periphery in racket handle 3 free end cross sections.Thereby this periphery is octagonal.

This end cover 2 can be fixed on the free end of racket handle 3 with any suitable mode, if handle 3 in a tubular form the time, it also can constitute the capping of handle 3, and this situation often runs into.

End cover 2 has three

trigonums

4,5,6 of difference mutually.Each delta all has a summit 7, this summit is just in time dropped on the longitudinal axis 3a of handle 3, one side each

delta

4,5,6 then being made of a limit in three adjacent sides of 4a, 5a, 6a of end cover 2 octagonal peripheries facing to summit 7.

Each

delta

4,5,6 is used for representing the zone that hypothenar hid that this handle 3 should passive movement person hand 8.On Fig. 2 and Fig. 4, indicate hypothenar with arrow 9.

Can distinguish 4,5,6 three deltas with any suitable mode, the most handy different method of colouring are distinguished.Like this, the beginner also just holds its racket handle 3 with correct angle position easily, that is to say, can adopt correct racket hold smoothly; Which like this, when playing each ball possibly, should have been hidden by the hypothenar 9 of beginner's hand as long as know corresponding to the zone in 4,5,6 three deltas.

Therefore, in order to adopt correct racket hold, as long as the sporter knows:

During a dozen forehands, he should hold the handle 3 of its racket in this wise, makes his hypothenar 9 hide with delta 4 corresponding misfortune 3 zones, as shown in Figure 2;

A dozen services, a normal backhand or make a call to when spiking, his hypothenar 9 should cover in and delta 5 corresponding handles 3 zones, as shown in Figure 3;

One is last, makes a call to one when lifting backhand, and he should hold handle 3 in this wise, his hypothenar 9 is covered in and delta 6 corresponding handles 3 zones, as shown in Figure 4.

Certainly, should stipulate out a certain datum mark (position), pre-determine what a angle position, then end cover 2 is fixed on the free end of racket handle 3 by this predetermined angular position by this datum mark with sporter's hand.In above-mentioned example, this datum mark (position) is exactly a hypothenar, come to determine the position of end cover 2 in this case, will make 4,5,6 three trigonums on the angle position is the racket wire side with racket screen frame 12() median surface 11 be that benchmark is arranged symmetrically.This correct positioning is the pointed location of Fig. 2 to Fig. 4 in the drawing just.

End cover 2 can still be made of diverse ways, sees that it is to constitute and a suitable annex of racket, sees perhaps whether its (when making handle) connects together with handle and decide.In fact, it can be very simple form, an automatic gummed film that is fitted on racket handle 3 free ends perhaps may be a rigid thin slice that is made of plastic or similar stuff exactly, and this thin slice has the installing (means) that can be fixed on racket handle 3 free ends.As mentioned above, end cover 2 can in a tubular form the time, constitute its capping at handle 3 equally.

End cover 2 can be made of a hoop cover equally, shown in 2a among Fig. 5.In the case, flat pieces 2 uses as the bottom, and its periphery then is made of lasso 2 ' a that a periphery is cylindricality, and the polygonal cross section of this lasso is consistent with the cross section of racket handle 3.The size of lasso 2 ' a to do make it can overlap enter racket handle 3 from by the And of end portion simultaneously diametrically lock ring live racket handle 3.At this moment, each

trigonum

4,5,6 is all prolonged by a column region that stretches along lasso 2 ' a outer surface, has the separator identical with each trigonum on this column region, they are 4 respectively ', 5 ', 6 '.This just helps the location that the sporter carries out correct racket hold, because this set makes each district more apparent.

For being easier to, the sporter positions to determine correct racket hold, another characteristics of the present invention are, on racket handle 3, a collar 14 is housed facing to the other end of the free end that has end cover 2, be marked with 4 at this cover ring outer surface "; 5 ", 6 " column region, each district all according to the column region of lasso 2 ' a of end cover 2a (4 '; 5 ', 6 ') in the direction of extension in a district arrange.

Fig. 6 and Fig. 2 to Fig. 4 are similar, overlap this end cover it is equipped with hoop cover 2 ' a whether all to have the 4th district, the 4th trigonum (also may column region) different with aforementioned three trigonums no matter it expresses another kind of racket end, now respectively with 13 and 13 ' sign.The pairing racket hold in 13 and 13 ' district can increase the effect that lifts of forehand, and this racket hold is referred to as " west hold " usually.But it is to be noted: this racket hold need have very that the sporter of rich experience could grasp in tennis practice, so this hold only is applicable to the sporter that those are outstanding.

Fig. 7 expresses the another kind of different embodiment of end cover of the present invention, and this end cover can be with cylindricality lasso 2 ' a, also can not be with cylindricality lasso 2 ' a.According to three or four

deltas

4,5,6 and 13 or may three or four column region 4 ', 5 ', 6 ' and 13 ', ", 5 ", 6 " and 13 " can not extend to the principle more than 180 ° with 4, two groups of deltas and garden column region can be set, arrange symmetrically with the axis 3 of racket handle 3 ' be benchmark in these two groups of districts.This set can make the sporter when rotating 180 ° on its racket not reason can not find trigonum or garden cylindricality subregion mark and make a careless move, grasp the racket hold thereby help the sporter.
