Abstract
The utility model relates to a baseball bat, which is formed by that a hollow outer casing layer with predetermined wall thickness is made of fibrous reinforcement plastics; the outer casing layer a striking part, a grasping and holding part and an elastic bend part which is positioned between the striking part and the grasping and holding part. The utility model is characterized in that the surface of at least one of all the parts is coated with one layer of elastic plastic film which is formed by the method of injection molding. So, because the outer casing layer of the baseball bat is provided with the protection and the cushioning balance of the elastic plastic film layer, compared with traditional baseball bats, the utility model has the advantages of better elastic property, damping capacity and surface strength.
Description
The utility model system is relevant with baseball bat, particularly about a kind of fibre reinforced plastic baseball bat.
As everyone knows, in baseball, baseball bat system is used for the instrument of the high speed ball being hit away for the user, therefore, advantage such as preferable baseball bat must possess light weight, rigidity is enough, elasticity is good and shock-absorbing power is strong, and the surface of bat also must be able to be born and the high speed spheroid enormous impact strength of moment.At present, the baseball bat of being made by fibre reinforced plastic is because light weight, intensity Gao Eryou replace the trend of wooden baseball bat gradually, yet, the fact shows, the fibre reinforced plastic baseball bat often makes in order to take rigidity into account that elasticity is affected, and the concussion of being experienced in the square stance grip part is quite big, both, its surface is fragile, can't bear bigger impact strength.
Therefore, the main purpose of the utility model promptly is to provide a kind of fibre reinforced plastic baseball bat of improvement, except the advantage that can possess light weight, good rigidly, more flexible good, the strong surface strength of shock-absorbing power is good etc. constitutes many conditions of high-quality baseball bat.
By being, the baseball bat of the utility model, empty external shell among the predetermined wall thickness is made by fiber reinforcement glue plastic cement by system, this outside shell has a strike portion (Impact Portion), one grip part (Grip portion), an and elastic bend part (Flexible bending portion) that is positioned between this strike portion and this grip part, it is characterized in that this outside shell pastes the Elastic plastic-rubber film of one deck with injection mo(u)lding on the surface, at least one position at aforementioned each position, by this, this baseball bat is owing to have the protection of this Elastic plastic-rubber rete, therefore, its outside shell during fabrication suitably attenuate in order to increase the elasticity of barred body; Moreover, the Sasser that square stance produced is then because of there being part to be absorbed by this Elastic plastic-rubber thin layer, so have preferable damping capaicty, and, this Elastic plastic-rubber film is used for the cushion can be as this outside shell impact bead body the time, the toughness of this club face will be increased and is difficult for breaking.
Below lift the preferred embodiment and the conjunction with figs. of some utility models now and do further explanation, wherein:
The 1st figure is the part sectional elevation of the utility model preferred embodiment one.
The 2nd figure is the part sectional elevation of the utility model preferred embodiment two.
The 3rd figure is the axial view profile of the utility model preferred embodiment three.
At first, see also the 1st figure, the baseball bat of the utility model preferred embodiment one (10) have one by the fiber of multilayer epoxy resin-impregnated (as carbon fiber, glass fibre etc.) the stacked coiling of textile board order and give empty outside shell (20) among the pressurized, heated hardened forming, one is positioned at the grip part (24) of lower end, and a elastic bend part (26) between aforementioned two ones, the surface of this driving part (22) has one section annular recess (221), one Elastic plastic-rubber film (28) is coated on the surface of this annular recess (26), its thickness is approximately identical with the degree of depth of this annular recess (221), with so that the surface of this annular recess (26) is concordant with this exterior layer shell (20), on making is with PU, PC and epoxy resin are just mixed raw material as this Elastic plastic-rubber film (28) with suitable ratio, and then be coated in this annular recess (221) with injection molding, by this, this Elastic plastic-rubber film (28) can be covered on the surface of this annular recess (221) tightly.In present embodiment the thickness of this layer Elastic plastic-rubber film (28) about 2mm and hardness by about 80 degree (hardness of this outside shell (20) be about 90 degree).
By as can be known aforementioned, the surface of this driving part (22) is expanded layer owing to have the less Elastic plastic-rubber film (28) of one deck hardness as buffering and guarantor, therefore, its shock-absorbing power will be strengthened, its surface toughness is strengthened in order to bear bigger impact strength.
See also the 2nd figure again, the baseball bat of the utility model preferred embodiment two (30) have equally one make by fibre reinforced plastic outside shell (32), this outside shell (32) formation one is positioned at the driving part (34) of upper end, one is positioned at the grip part (36) of lower end, and an elastic bend part (38) that is positioned between aforementioned two ones.The feature of this baseball bat (30) promptly is the Elastic plastic-rubber film (40) of one deck injection mo(u)lding that driving part (34) surface of this outside shell (32) pastes, about the about 2mm of thickness of this Elastic plastic-rubber film (40).Certainly, the Elastic plastic-rubber film (28) of its effect that can reach and this embodiment one is identical.
At last, see also the 3rd figure again, the baseball bat of the utility model preferred embodiment three (50) also have equally one by fiber reinforcement glue make and the tool predetermined thickness among empty outside shell (52), this outside shell (52) constitutes a driving part (54), one grip part (56), and an elastic bend part (58) that is positioned at the two.The surface that is characterised in that this each position of outside shell (52) of this baseball bat (50) all is covered with the Elastic plastic-rubber film (60) of one deck injection mo(u)lding; the raw material system of this Elastic plastic-rubber film (60) is by the PU of proper proportion; PC and epoxy resin constitute; hardness after its moulding is about between 75 degree-80 degree; thickness is then about 1.5mm; by this; the driving part (54) of this baseball bat (50) is owing to have this Elastic plastic-rubber film (60) as elastic cord breaker; therefore the increase that the toughness on its surface will be more traditional; and this elastic bend part (58) is owing to have this Elastic plastic-rubber film (60) as protective layer; therefore be positioned at this partly outside the thickness of shell can attenuate; in other words; what promptly the elasticity at this position can be more traditional is good; moreover; because shell (50) surface all has an Elastic plastic-rubber film (60) than its softness (being that hardness is less) outside whole baseball bat, therefore the reforming phenomena that produced of batting is sent in the process of this grip part (56) and can be subdued in large quantities at this driving part (54) certainly.
Claims (2)
1, a kind of fibre reinforced plastic baseball bat of improvement, system makes one by fibre reinforced plastic and has empty outside shell among the predetermined wall thickness, this outside shell has a strike portion, one grip part, and an elastic bend part that is positioned between this strike portion and this grip part, it is characterized in that this outside shell is covered with the Elastic plastic-rubber film of one deck with injection mo(u)lding on surface, at least one position, aforementioned each position.
2, by the described baseball bat of claim 1, it is characterized in that each surface, position of this outside shell all is covered with the Elastic plastic-rubber film of one deck with injection mo(u)lding.
