Abstract

The utility model relates to an exercising ball for golf. The utility model is characterized in that a hollow spherical body is sewed with more than two sheets of surface cloth, and a gap is reserved when the hollow spherical body is sewed; a right amount of cellulosic material is filled in the spherical body from the gap before the gap is stitched, and then the center of the spherical body is filled with a right amount of thermosetting resin to form an object with certain weight. The utility model has the advantages that the evenness is high, the gravity center of the utility model is kept at the center of the spherical body, and the structure is simple.

Description

The Golfing practice ball

The utility model relates to a kind of Gao Er ball medicine ball, refers in particular to a kind of Golfing practice ball that its out of roundness and steadily of centre of gravity remain on the center of circle that improves.

Generally specialize in the place that indoor golf balls swings,, all adopt the Golfing practice ball to use for exercise from security consideration.And the Golfing practice ball, the present product that plastic cement and two kinds of materials of cellulosic are arranged respectively.Fig. 1 is the organigram of plastic cement Golfing practice ball, and with the plastic material ejection formation, its inside is hollow structure, and is surperficial then reserve to connect the perforation of boring structure.This plastic cement Golfing practice ball with low cost, but swinging when hitting, can cause the spheroid distortion and cause the phenomenon of unbalance skew, the path deflection that spheroid is flown aloft, different with the leap path of actual golf, thereby can't know actual exercise achievement.

Cellulosic golf practice ball is at the invention of the shortcoming of above-mentioned plastic cement golf practice ball, is after the soft fiber material is filled to sphere, with cloth coat make spherical.And this cellulosic divides in advance to fill out and is the two halves spheroid, uses the suitable circular cloth of two areas respectively with its coating again, then two hemisphere is stitched into an integral body.The stable gravity center of this cellulosic golf practice ball is qualitative preferable, but when cloth is overmolding to hemisphere, its edge is difficult to form complete semicircular body corner, and the size of two semicircular body also is difficult to definitely identical, concentrate on and be sewn to the selvedge size in the middle of the hemispheroidal plane and also be difficult to identical, thereby its straight circularity is not good after being sewn into spheroid, and distribution of weight is inhomogeneous, causes center of gravity can't be positioned at its circle centre position just.Though therefore this cellulosic Golfing practice ball has improvement than plastic cement Golfing practice ball, because of actual quality bills of materials is difficult to reach theoretic even effect, still common cloth is in flight, and the path is the untrue situation of skew obviously.

The purpose of this utility model is to provide a kind of can improve its out of roundness, makes stable gravity center, remain on the Golfing practice ball in the center of circle, directly stable and true in hollow habit walking along the street to guarantee spheroid, helps observing actual exercise achievement.

The purpose of this utility model realizes by following technological means: a kind of Golfing practice ball, be sewn into hollow sphere by table cloth identical shaped more than two or two, and inner fiberfill fibers material forms, and it is characterized in that: table cloth is in the involutory slit that is reserved with one for the fiberfill fibers material when being sewn into hollow sphere; Filled an amount of fibrous material and the slit sewed up after the circle centre position of spheroid inject from the outside an amount of is arranged and combines and solidify the all-in-one-piece thermosetting resin with the fibrous material of circle centre position; The involutory table cloth that makes up spheroid of piecing together is the shape that is similar to Arabic numerals 8.

Advantage of the present utility model is: 1, the circle centre position of spheroid sets firmly one and has the object of suitable weight, thereby makes the spheroid steadily of centre of gravity remain on circle centre position, can guarantee that the skyborne flight path of spheroid is stable and true, helps observing actual practice effect; 2, two split identical shaped table cloth mutually and be sewn into hollow sphere after, again to inner fiberfill fibers material, therefore inner fibrous material can evenly distribute, its out of roundness of the spheroid that is sewn into like this is preferable relatively, and the object that is installed in circle centre position is difficult for skew, its center of gravity stable preferable; 3, structure is simpler and easy than prior art, and is easy to make shaping.

Describe structure of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of existing plastic cement portion Golfing practice ball;

Fig. 2 is a table cloth decomposing schematic representation of the present utility model;

Fig. 3 makes the state diagram of back reserving gaps for the utility model:

Fig. 4 is the action schematic diagram of the utility model from slit fiberfill fibers matter;

Fig. 5 is the action schematic diagram that slit of the present utility model is sewed up;

Fig. 6 is sewn into the outside drawing of complete spheroid for the utility model;

Fig. 7 is the action schematic diagram that injects thermosetting resin to the spheroid center of circle of the present utility model;

Fig. 8 is a cutaway view of the present utility model.

Among the figure: 1 table cloth, 2 sutures, 21 slits, 3 fibrous materials, 4 spheroids, 5 thermosetting resins.

As Fig. 2, Fig. 3 and shown in Figure 8, the utility model is made of table cloth 1, fibrous material 3 and thermosetting resin 5, and wherein: table cloth 1 is two to be split and identical shaped cloth mutually, after it is involutory mutually, be sewn into the hollow ball body with suture 2 along its edge, and reserve slit 21 one.

As shown in Figure 4 and Figure 5,21 to an amount of fibrous material 3 of the inner filling of spheroid from the slit, with suture 2 slit 21 is sewed up again, forms complete spheroid 4 (as shown in Figure 6).

As shown in Figure 7 and Figure 8, inject an amount of thermosetting resin 5 with four injection tubes to the circle centre position diagonal angle of spheroid 4, promptly combine after thermosetting resin 5 is cooled off and be cured as one with the fibrous material 3 of circle centre position, make the circle centre position of spheroid 4 set firmly the object of a suitable weight, reach the effect that the spheroid steadily of centre of gravity remains on its center of circle.

Claims

1, a kind of Golfing practice ball, be sewn into hollow sphere by table cloth identical shaped more than two or two, and inner fiberfill fibers material forms, and it is characterized in that: table cloth is in the involutory slit that is reserved with one for the fiberfill fibers material when being sewn into hollow sphere; Filled an amount of fibrous material and the slit sewed up after the circle centre position of spheroid inject from the outside an amount of is arranged and combines and solidify the all-in-one-piece thermosetting resin with the fibrous material of circle centre position.

2, Golfing practice ball according to claim 1 is characterized in that: the involutory table cloth that makes up spheroid of piecing together is the shape that is similar to Arabic numerals 8.
