Abstract

The invention discloses a bat with shock-absorbing effect. A head and a joining part of the bat are both made of shock-absorbing materials, and the head, a striking part, the joining part and a gripping handle part are integrated into a whole, thus when a ball collides with the bat to generate a shaking force during the striking by the bat, the head and the joining part can be used to absorb the shaking force to effectively reduce the shaking force and ensure that the paralysis and ache of a palm and a wrist of a striker caused by the shaking force is minimized to avoid the injury of sports and the striker can more effectively play striking power.

Description

The bat of tool shock-absorbing effect

Technical field:

The present invention relates to a kind of bat, especially head and the convergence part that refers to a kind of bat all utilizes the shock-absorbing material to make, when hitting, can absorb the shaking force that produces when ball and bat clash into, lower shaking force and bring the uncomfortable of player and avoid moving injury, use the most effective strike power of performance.

Background technology:

Along with medical science is showing improvement or progress day by day, people's life-span also and then prolongs many, and the health that will secure good health, except good eating habit, motion is the most basic key element, so athleticism field, baseball practice field and gymnasium are also more and more, add that baseball in recent years is in vogue in the whole world, and the enjoyment that people also have deep love for swinging and hit very much, and just hit the bat of usefulness, except the duty rod uses the wooden bat of the preferable strike skill of palpus, sparetime and student's baseball are in order to improve the effect of strike, mostly use the bat of aluminum bat or composite, and with regard to the structure of aforementioned aluminium bar and composite material bat, see also as shown in Figures 1 and 2, mainly be to extend a dozen for 11 times at a head than big termination to hit portion 12, the convergence part 13 of strike portion 12 next extension one rapid reduced outside diameter, convergence part 13 downsides then extend a handle portion 14, the hollow bar that this known bat 1 is formed in one, and swinging when hitting as the striker, in the moment of ball and bat 1 collision, will produce one shaking force, and this shaking force can be by collision place upwards, transmit the below, and the downward shaking force that transmits can reach striker's both hands through handle portion 14, and fast more greatly when ball, healing that then shaking force is relative is big, so that allow the striker in the moment of swinging the strike collision, will feel that palm and wrist can produce the paralysis sense of aching, and when the strike posture is not good, move injury easily, and can cause the due strike level of to bring into play, and then can't get desirable achievement, the necessity of being improved is arranged in fact.

Summary of the invention:

Technical problem to be solved by this invention is: at above-mentioned the deficiencies in the prior art, a kind of bat with shock-absorbing effect is provided, mainly be to make the head of bat and convergence part form a shock-absorbing effect, and can swing strike and ball impact moment, the shaking force that produces in the time of can absorbing ball and bat bump, lower shaking force and bring the uncomfortable of player and avoid moving injury, use the most effective strike power of performance.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of bat of tool shock-absorbing effect, this bat has a head, this head extends the strike portion of a flat grade, strike portion extends the convergence part of a rapid reduction external diameter again, a handle portion is then extended in the convergence part, this strike portion and handle portion are made by aluminium or composite, be characterized in: make with vibration absorptive material described head and convergence part, and head locates to form an annular groove that inwardly concaves therebetween, strike portion then forms one to projecting inward bulge loop in the termination of hollow, this head combines with the bulge loop of annular groove with strike portion, this convergence part forms a protuberance at the place, centre, and on protuberance, downside all forms an annular groove that inwardly concaves, on two annular grooves, downside extends the empennage of different length more respectively, and this convergence part reaches with protuberance, the shape of two annular grooves and strike portion and shank part inlay card are combined as a whole down.

So, the head of this bat and all shock-absorbing materials of convergence part are made, in the strike of swinging, when ball and bat collision generation shaking force, can be absorbed by head and convergence part, and can effectively reduce shaking force, it is minimum to allow the striker drop to because of shaking force causes the paralysis of palm and wrist to ache, avoid the generation of athletic injury, to allow the striker more effective performance hit power.

Label declaration:

1 bat, 11 heads, 12 strike portions, 13 convergence parts

14 handle portions, 2 heads

21 annular grooves, 3 strike portions, 31 bulge loops

4 convergence parts, 41 protuberances, 42 annular grooves

43 empennages, 5 shank parts

The specific embodiment:

Be the effect that can be easier to structure of the present invention and can reach, cooperate graphic being described as follows now.

Bat of the present invention is meant the hollow bat of aluminium or composite material forming or the two collocation moulding, please cooperate referring to Fig. 3 and Fig. 4, this bat mainly is the strike portion 3 of extending a flat grade at a head 2, strike portion 3 extends the convergence part 4 of a rapid reduction external diameter again, a shank part 5 is extended in 4 of convergence parts, wherein, head 2 is to get with the vibration absorptive material moulding with convergence part 4, this vibration absorptive material can be rubber (RUBBER), thermoplastic polyurethanes elastomer (TUP) or fiber-reinforced plastic materials such as (FRP), and, head 2 locates to form an annular groove that inwardly concaves 21 therebetween, strike portion 3 then forms one to projecting inward bulge loop 31 in the termination of hollow, in addition, 4 of convergence parts form a protuberance 41 at the place, centre, and on protuberance 41, downside all forms an annular groove that inwardly concaves 42, on two annular grooves 42, downside extends the empennage 43 of different length more respectively, and its manufacturing, be to mold head 2 and convergence part 4 with the shock-absorbing material earlier, insert head 2 and convergence part 4 in the mould again and strike portion 3 and shank part 5 utilize composite or aluminium one-body molded, form the bat of one, also but shank part 5 is a composite, strike portion 3 then is an aluminium, but the bulge loop 31 of the recessed annular groove 21 of head 2 mats and strike portion 3 is inlay card mutually, 4 of convergence parts with protuberance 41 and on, the shape of two annular grooves 42 combines with strike portion 3 and shank part 5 inlay cards down, making whole is firm bonding state, and does not have the disappearance that comes off.

Because the head 2 and 4 two positions, convergence part of bat of the present invention are made with the material with shock-absorbing effect, then when swinging strike, after shaking force that ball and strike portion 3 impact moment are produced reaches the below upward and transmits, can be absorbed by head 2 and convergence part 4 respectively, make the shaking force that conducts to palm and wrist place drop to minimum, then by the attenuating of shaking force, the sensation minimizing that nature can make palm and wrist ache and benumb, not only can avoid the formation of athletic injury, and can allow the striker strike power should be arranged more effective performance, to obtain preferable strike effect.
