Abstract

The utility model relates to a safety baseball which is composed of a baseball core and a baseball coat coated outside, wherein, the baseball core is formed by orderly coating and stacking from inner to outer a firstly baseball core layer, a second baseball core layer, a third baseball core layer and a fourth baseball core layer. The first baseball core layer is a spherosome which is positioned in the innermost layer of the baseball core, and the second baseball core layer is a rubber layer which has lower hardness and density and is coated on the outside of the first baseball core. The third baseball core layer is a rubber layer which has hardness lower than that of the first baseball core layer and higher than that of the second baseball core layer and is coated on the outside of the second baseball core layer, and the fourth baseball core layer is a rubber layer which has the same hardness and density with the second baseball core layer and is coated on the outside of the third baseball core layer. The utility model has the advantages of high safety and more proximity to true baseballs.

Description

Safety baseball

The utility model relates to a kind of ball of throwing usefulness, refers to a kind of the reduction when touching body the injury that human body caused especially, and has more the Safety baseball of the formal baseball sense of reality.

Safety baseball mainly is to play for the child, therefore when avoiding excellent touch the body the child being caused serious injury is the problem of overriding concern, a kind of Safety baseball (as shown in Figure 1) has appearred in the market, it mainly is to be made of a kind of PU plastic cement material foaming-formed centre of sphere A and its outer football shirt B who coats, because the foam characteristics of PU plastic cement material relation, cause the top layer of this centre of sphere A to be the hard shape, past more inside is then soft more, though therefore this Safety baseball can keep just round and not yielding, but because its top layer is harder lamina, therefore when touching the person with very big speed, it still can damage human body, the extent of injury that it caused is more not inferior with baseball than regulation game, again and its be the centre of sphere A structure that is soft shape more toward in, obviously with regulation game with the centre of sphere of baseball more toward in then be that hard shape structure is then different fully, so also can reduce the sense of reality in its use.

The purpose of this utility model is to improve the existing existing above-mentioned shortcoming of Safety baseball, provides a kind of and can reduce when touching body to the injury that human body caused then more approaching the in the use formally Safety baseball of the baseball sense of reality greatly.

For achieving the above object, the utility model is taked following technical scheme:

A kind of Safety baseball, it is to be made of a centre of sphere and football shirt that coats outside it, the described centre of sphere is to be made of toward outsourcing is folded interior in regular turn first ball center layer, second ball center layer, the 3rd ball center layer and the 4th ball center layer, wherein: first ball center layer, be to be shaped to a spherosome, and be positioned at the innermost layer of the centre of sphere by a kind of high rigidity, highdensity rubber material foaming; Second ball center layer is that it is coated on the outside of first ball center layer by the rubber layer of a kind of hardness, rubber material foaming moulding that density is lower; The 3rd ball center layer is low than first ball center layer by a kind of hardness, density, and than the rubber layer of the rubber material foaming moulding of second centre of sphere floor height, it is coated on the outside of second ball center layer; The 4th ball center layer is that it is coated on the outside of the 3rd ball center layer by the rubber layer of a kind of hardness, rubber material foaming moulding that density is identical with second ball center layer.

Embodiment conjunction with figs. of the present utility model is described in detail as follows:

Fig. 1 is the Safety baseball structural representation of commonly using.

Fig. 2 is the utility model embodiment perspective view.

Fig. 3 is the utility model embodiment sectional structure chart.

As shown in Figure 2, the utility model embodiment coats a football shirt 2 outside a centre of sphere 1, and wherein, this football shirt 2 is identical with the outer football shirt of general existing baseball, and is not emphasis of the present utility model place, so do not repeat them here.

The above-mentioned centre of sphere 1 that mainly focuses on of the utility model structure is to be made of toward outsourcing is folded interior in regular turn first ball center layer 11, second ball center layer 12, the 3rd ball center layer 13 and the 4th ball center layer 14, wherein:

First ball center layer 11 (seeing also Fig. 3) is to be made by a kind of high rigidity, the moulding of highdensity rubber material foaming, and it is a spherosome, is positioned at the innermost layer of the centre of sphere 1.

Second ball center layer 12 (still seeing also Fig. 3) is to be made by a kind of hardness, rubber material foaming moulding that density is lower, and it is coated on the outside of first ball center layer 11.

The 3rd ball center layer 13 (also seeing also Fig. 3) is low than first ball center layer 11 by a kind of hardness, density, and makes than the 12 high rubber material foaming moulding of second ball center layer that it is coated on the outside of second ball center layer 12.

The 4th ball center layer 14 (seeing also Fig. 3 again) is to be made by the rubber material foaming moulding identical with second ball center layer 12 of a kind of hardness, density, and it is coated on the outside of the 3rd ball center layer 13.

Again, first ball center layer 11, second ball center layer 12, the 3rd ball center layer 13 and the 4th ball center layer 14 according to its different hardness, density selection after, again selected material is made sheet and folded by interior past outsourcing in regular turn, and insert simultaneously and carry out the foamable moulding in the mould, therefore, first ball center layer 11, second ball center layer 12, the 3rd ball center layer 13 and the 4th ball center layer 14 behind the foaming can be combined into complete and a centre of sphere 1 with multi-level and different hardness and density.

From the above mentioned, the utility model because be positioned at the centre of sphere 1 outermost the 4th ball center layer 14 hardness and density lower, therefore when baseball striking human body, the flexibility that can be had by the 4th ball center layer 14 and form a protective layer and contact with human body is to reduce its extent of injury to human body; Simultaneously, can be by the 3rd ball center layer 13 and second ball center layer 12, the soft durometer of different levels absorbs impulsive force, thereby can reduce its extent of injury, moreover, can be by the 3rd ball center layer 13 than the hard shape, can improve it and hold sense and can be too not soft, make it can be near the sense of holding of regulation game with baseball; Again, it can be by the high rigidity of first ball center layer 11 and high density to improve the weight of baseball, make it near the sense of reality of regulation game with baseball, maybe can adjust the hardness of first ball center layer 11 and density and adopt weight grading, child for all ages and classes layer uses, especially, first ball center layer, the 11 quality maximums and the hardness that are positioned at the centre of sphere 1 innermost layer are the highest, and be coated on the second outer ball center layer 12 of first ball center layer 11, the 3rd ball center layer 13 and the 4th ball center layer 14 are again the structural design of different hardness and density, therefore also help near the structure of regulation game with baseball, and then can reduce injury when touching the person, and the sense of reality that can more approaching formal baseball.

By among the above and the embodiment shown in the drawings as can be known, the technological means that the utility model used really can reach its intended purposes, thereby provide a kind of injury that can reduce greatly when touching the person, and the Safety baseball of the more approaching formal baseball sense of reality, so have practicality and the progressive that significantly improves Safety baseball, and it is unprecedented really, so meet the important document of patent.
