Abstract
The utility model relates to a composite material racket, which comprises a batting component with bigger external diameter and a gripping component with smaller external diameter, wherein, the adjacent part of the batting component and the gripping component forms a tapered section; the gripping component comprises an inner layer and an outer layer shell walls, wherein, the inner shell layer has rigidity, and the outer shell layer has bending elasticity.
Description
Technical field
The utility model designs a kind of ball game articles for use, is meant rackets such as a kind of baseball or softball especially.
Background technology
Bat has basic weight and size restrictions, and the producer must be at the strike position of bat under this restriction, the holding area, and the design of difference in functionality is done at deflection position etc., in the hope of whole best effect.Usually can require high strength and resistance to impact at hitting the position, then require preferable shock absorption and grip comfort at the holding area, and the bending point of bat also be the problem that the designer must pay attention to.Known bat mostly is with whole bat of uniform material moulding, its material can be wood, metal or fibre reinforced resin, some does local reinforcement design at hitting the position again, only the bat of this kind uniform material for the strike portion performance requirement different with the grip part very difficulty take into account.Moreover in advance skill mostly is that strike portion at bat improves, and is very fewly improved at the grip part.As United States Patent (USP) 5,131, shown in 651, be minority at the patent of shock absorption and bending elasticity before case, it is to be provided with most holes, the sheathed again clad in the outside between the holding area of bat and taper deflection position, reach shock-absorbing by this and reduce rigidity, increase the purpose of bending elasticity.But will be on carbon fiber reinforcement sandwich material the most holes of moulding, trouble rather on processing procedure.
The utility model content
Main purpose of the present utility model is to provide a kind of composite material bat, and its holding area has preferable shock absorption and bending elasticity, and does not influence the structural strength of hitting the position.
For reaching above-mentioned purpose, according to a kind of composite material bat provided by the utility model, be to form in conjunction with the less gripping member of an external diameter by the bigger strike member of an external diameter, wherein this gripping member is by interior, outer two layers of shell wall constitute, its hypostracum rigidity is stronger, outer shell is then than the tool bending elasticity, by this, make gripping member have preferable bending elasticity and shock absorption, and can keep enough structural strengths, but hit then independent design of member, adopt the more material and the structure of resistance to impact, and it is good therefore to be combined into overall performance, play the good bat of sense.
Specifically, a kind of composite material bat that the utility model provides, include bigger strike member of an external diameter and the less gripping member of an external diameter, then form a taper section in abutting connection with the position what hit member and gripping member, this gripping member includes inside and outside two layers of shell wall, wherein hypostracum is than the tool rigidity, and outer shell is than the tool bending elasticity.
Described composite material bat, wherein the outer shell of this gripping member is made by fibrous reinforcement thermoplastic plastic material.
Described composite material bat, wherein this fibrous reinforcement thermoplastic plastic material is nylon or ABS (Acrylnitrile-Butadiene-Styrene, acrylonitrile-butadiene-styrene copolymer).
Described composite material bat, wherein the hypostracum of this gripping member is made by fibrous reinforcement thermoset plastic material or metal material.
Described composite material bat, wherein this fibrous reinforcement thermoset plastic material is to be base material with epoxy resin.
Described composite material bat wherein more is provided with a shock-absorbing interlayer between inside and outside shell.

Fig. 1 is the outside drawing of the utility model embodiment;
Fig. 2 is the cutaway view along 2-2 hatching line among Fig. 1;
Fig. 3 is the cutaway view along 3-3 hatching line among Fig. 1;
Fig. 4 is the utility model bat batting stress analysis figure in holding area when crooked;
Fig. 5 is analogous to Fig. 3, is the structural representation of the utility model second embodiment.
The specific embodiment
Extremely shown in Figure 2 as Fig. 1, bat of the present utility model be by the bigger pipe shape of an external diameter hit the less pipe shape gripping member 20 of member 10 and an external diameter combine constitute, then form a taper section in abutting connection with the position what hit member and gripping member, wherein this gripping member 20 includes inside and outside two layers of shell wall 21,22, hypostracum 21 is by the fibrous reinforcement thermoset plastic material, for example carbon fiber or glass fibre or boron fibre reinforced mediate amount epoxy resin; Or metal material, for example aluminium or titanium or magnesium alloy etc. or the thermoplastic material of tool rigidity are made, has preferable rigidity, outer shell 22 then is by fibrous reinforcement thermoplastic plastic material or engineering plastics supporting material, for example carbon or glass or boron fibre reinforcement nylon, or ABS makes, its rigidity than hypostracum 21 a little less than, but bending elasticity and shock absorption are all good than hypostracum.
As shown in Figure 4, as bat stressed F and when crooked of bat, its gripping member 20 A side in the drawings is the tension force that is subjected to f1, f2, the B side then is subjected to the pressure of f1, f2 in the drawings, because outer shell 22 rigidity are more weak softer, its relative telescopic resilience is then stronger, and it is configured in the outside, can improve the bending elasticity and the shock absorption of bat.Configuration by inside and outside two shell dissimilar material properties, only need to select suitable material and thickness, from designing desirable gripping member, cooperate the strike member of strengthening in addition again, oneself can produce all very superior bat on the performance of integral body and percussion feeling.
As shown in Figure 5, it is the structural representation of the utility model second embodiment, its internal layer 31 adopts metal material, outer 32 adopt thermoplastic, between internal layer 31 and outer 32, more be provided with an interlayer 33, use for example vibration absorptive material of butyl rubber tool shock-absorbing characteristics such as (butyl rubber), further absorb and hit the amplitude of vibration that is produced, reduce the injury of striker's arm.
