Abstract

The utility model relates to a sports ball which is a structural improvement of the existing sports balls, such as basketballs, volleyballs, footballs, etc. The sports ball comprises an inner tube 7 with an inflating valve, a yarn winding layer and a surface layer 6 outside the inner tube 7. The utility model is characterized in that the adjacent inner tube 7, the yarn winding layer and the surface layer 6 are divided by foaming layers also playing a connecting effect. The utility model has the advantage that the sports ball reduces the hardness of a ball body and thus gives users a soft feeling under the hypothesis of ensuring the performance indexes of the existing ball body.

Description

Ball for sports

The utility model relates to ball in the athletic sports appliance, more precisely to the improvement of basketball, football, vollyball, rugby globoid.

Existing ball for sports, its inner tube of a tyre twines between layer and the top layer combining with paste or solid.The shortcoming of this structure is that spheroid is really up to the mark, lacks flexibility.

The utility model purpose is: overcome the above-mentioned deficiency of existing similar sport ball constructions, improve the pliability of spheroid.

Ball for sports provided by the utility model comprises the inner tube of a tyre that has inflation and chew, be positioned at the inner tube of a tyre outside twine layer and top layer, it is characterized in that: between the inner tube of a tyre and top layer, foaming layer is set.

Above-mentioned foaming layer is arranged at the adjacent inner tube of a tyre, twines layer, between the top layer.

In order to obtain good flexibility, preferred version of the present utility model is: between the inner tube of a tyre and top layer, set gradually interior foaming layer, twine layer, middle foaming layer, secondary twine layer and outside foaming layer.

Another preferred version of the present utility model is: the aforesaid layer that twines is made and twined yarn foaming mixed layer.

Introduce embodiment of the present utility model below in conjunction with Figure of description:

Figure of description 1 is a structural representation of the present utility model;

Figure of description 2 is section of the present utility model (signal) figure;

In the accompanying drawings 1---interior foaming layer, the middle foaming layer of 2---twining layer, 3---, 4---secondary twines layer, and 5---outer foaming layer, 6---the top layer, 7---the inner tube of a tyre.

As shown in the figure, the utlity model has the inner tube of a tyre 7 of conventional ball for sports, twine layer and top layer 6.Have valve on the inner tube of a tyre 7.With conventional ball with stick with paste or solid with the inner tube of a tyre, to twine the version that layer and top layer bond together different, the utility model substitutes with foaming layer and sticks with paste or solid, and finishes the inner tube of a tyre 7, twines the combination between layer and the top layer 6.

In order to ensure result of use of the present utility model, the yarn amount that the twines branch that illustrated preferred version will be identical with original ball for sports twines yarn as secondary, and formation twines layer 2 and secondary twines layer 4, thereby reduced the hardness that twines layer.Twine layer 2 and secondary and twine layer 4 preferential versions of selecting to twine yarn foaming mixed layer.Should be pointed out that foregoing description is not got rid of selects the selection that singly twines the version that layer cooperates with foaming layer for use.

Selecting alternative original solid of foaming layer or paste is outstanding contributions of the present utility model.The inner tube of a tyre 7, twine between layer and the top layer 6 with foaming layer and separate, cause and separate and positice ground effect, form the soft function of ball.Foaming layer plays then effect simultaneously.Illustrated embodiment at the inner tube of a tyre 7 and twine be provided with between the layer 2 in foaming layer 1; Twine layer 2 and secondary twine be provided with between the layer 4 in foaming layer 3; Secondary twine be provided with between layer 4 and the top layer 6 outside foaming layer 5.

Version of the present utility model can be widely used on basketball, football, vollyball and the rugby.

The utility model has the advantages that: under the front topic that guarantees the spheroid property indices, reduced ball Body hardness is given soft sensation.
