Abstract

An improving ball structure. Several protruding grains are evenly distributed on the ball surface; a concave part is set at the middle of part or the whole of the protruding grains, so that the surface friction coefficient of the ball can be further enhanced and the control of the ball can be improved; the concave part of the protruding grains would be better in the shape of concave arc surface. This utility model would further enhance the surface friction coefficient of the ball, thus improving the control of ball.

Description

The structure of improved ball

Technical field

The utility model relates to a kind of ball, relates in particular to a kind of skin-friction coefficient that can further improve ball, and then helps to improve the structure of the improved ball of ball-handling property.

Background technology

As shown in Figure 1 and Figure 2, some ball (ball as basketball, dodgeball etc.) all can be furnished with a plurality of protruding grains 11 at the surperficial average mark of ball 10 for improving the ball-handling of ball 10, shown in Figure 1A, 2A, to increase the skin-friction coefficient of ball 10.

Above-mentioned existing ball, though be furnished with a plurality of protruding grains 11 at the surperficial average mark of ball 10, and increase the skin-friction coefficient of ball 10, and then help to improve ball-handling property; But with its structure, must be that the surface of ball 10 is in the enough coefficient of frictions of drying regime competence exertion, in other words, if when the surface of ball 10 is in humidity or water state is arranged, then its skin-friction coefficient will reduce, and then reduces the ball-handling property.

The utility model content

Technical problem underlying to be solved in the utility model is, overcomes the defective of existing ball existence, and a kind of structure of improved ball is provided, and can further improve the skin-friction coefficient of ball, and then helps to improve ball-handling property.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of structure of improved ball, the surperficial average mark of ball is furnished with a plurality of protruding grains, it is characterized in that: these protruding all or part of central authorities are provided with a depressed part, can further improve the skin-friction coefficient of ball by this depressed part, and then the ball-handling that helps to improve ball.

The structure of aforesaid improved ball, wherein depressed part is good with a cancave cambered surface.

The utility model can further improve the skin-friction coefficient of ball, and then helps to improve ball-handling property.

The number in the figure explanation:

The prior art part

10 balls

11 protruding grains

The utility model part

20 balls

21 protruding grains

22 depressed parts

The specific embodiment

As shown in Figure 3, Figure 4, ball 20 of the present utility model is furnished with a plurality of protruding grains 21 in surperficial average mark equally with existing ball; It is for Chuang Dar Industrial Co., Ltd makes technological means and structural feature thereof that purpose uses:

These protruding all or part of 21 central authorities are provided with a depressed part 22, and as shown in Figure 3A, this depressed part 22 is good with cancave cambered surface, shown in Fig. 4 A.

Structure design by above-mentioned can utilize this depressed part 22 further to improve the skin-friction coefficient of ball, and then help to improve the ball-handling of ball.

From the above and graphic shown in embodiment as can be known, the utility model really can reach the purpose of creation, provides a kind of and can further improve the skin-friction coefficient of ball, and then help to improve the ball structure of ball-handling property; Therefore, compare with existing ball and really to have obvious improvement and practicality, and its structure is really unprecedented, meets the important document of novel patent, so propose patent application in accordance with the law.

The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.

Claims

1. the structure of an improved ball, the surperficial average mark of ball are furnished with a plurality of protruding grains, it is characterized in that:

These protruding all or part of central authorities are provided with a depressed part.

2. the structure of improved ball according to claim 1 is characterized in that described depressed part is a cancave cambered surface.
