Abstract

The invention discloses a soft rattan ball, which relates to a sports article and comprises an outer surface, a wall thickness and an inner surface, wherein the outer surface and the inner surface are respectively positioned at the outer side and the inner side of the wall thickness; the sphere formed by the outer surface, the wall thickness and the inner surface is a soft hollow sphere. The soft rattan ball of the invention changes the rattan ball from 'hard' to 'soft', thus reducing the damage caused by the impact of the rattan ball; the appearance of simulated rattan texture and holes makes the soft takraw ball more similar to a traditional takraw ball.

Description

Soft rattan ball

Technical Field

The invention relates to sports goods, in particular to a soft rattan ball.

Background

Sepaktakraw is a formal permanent project for the subaffian. The initial takraw ball is a hollow ball woven by 9-11 single-layer natural rattans with the width of 3-4mm and the thickness of 3-4mm, and the takraw ball which is made of plastic material, namely the takraw ball woven by plastic takraw ball belts, is used for the match at present. The takraw balls have the defects that the takraw balls are too hard and basically have no elasticity, people are easily accidentally injured in the training process, and beginners have great difficulty in learning.

Chinese utility model patent application nos. 200920351070.6, 200920292190.3 disclose "soft takraw ball" and "new takraw ball", respectively, which are far from the traditional braided takraw ball in appearance and lose operability though the problem of hardness is solved.

Disclosure of Invention

The invention aims to solve the defects in the prior art, and provides a soft rattan ball which is made of soft materials and has the appearance consistent with that of a traditional rattan ball, so that the problems that the existing rattan ball body is too hard and has too large difference with the appearance of the traditional braided rattan ball are solved.

In order to achieve the purpose, the invention adopts the following technical scheme:

a soft takraw ball comprising an outer surface, a wall thickness and an inner surface, the outer and inner surfaces being located respectively outboard and inboard of the wall thickness; the sphere formed by the outer surface, the wall thickness and the inner surface is a soft hollow sphere.

Furthermore, 12 holes are arranged on the wall thickness between the outer surface and the inner surface.

Furthermore, the outer surface is also provided with strip-shaped textures which are used for simulating rattans and increasing friction strip-shaped textures and are matched with the holes.

Further, the thickness of the wall thickness prevents the ball from being depressed.

Compared with the prior art, the invention has the beneficial effects that:

the soft rattan ball of the invention changes the rattan ball from 'hard' to 'soft', thus reducing the damage caused by the impact of the rattan ball; the appearance of simulated rattan texture and holes makes the soft takraw ball more similar to a traditional takraw ball.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention and not to limit the invention.

Fig. 1 is a schematic view of the overall structure of a soft takraw ball according to the present invention.

In the figure: external surface 1, wall thickness 2, internal surface 3, holes 4, and texture 5 strips.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Example 1

A soft takraw ball comprises an outer surface 1, a wall thickness 2 and an inner surface 3, wherein the outer surface 1 and the inner surface 3 are respectively positioned at the outer side and the inner side of the wall thickness 2; the sphere formed by the outer surface 1, the wall thickness 2 and the inner surface 3 is a soft hollow sphere.

12 holes 4 are arranged on the wall thickness 2 between the outer surface 1 and the inner surface 3.

The outer surface 1 is also provided with a stripe 5 for simulating rattans and increasing the friction stripe and co-operating with the holes 4.

The wall thickness 2 is of a thickness that prevents the ball from collapsing under compression.

Example 2

A soft takraw ball comprises an outer surface 1, a wall thickness 2 and an inner surface 3, wherein the outer surface 1 has a strip texture simulating a traditional takraw ball weaving method, and the circumference of the outer surface 1 is preferably 420mm-560 mm; the wall thickness 2 is a solid part of a sphere and is made of flexible polyurethane foam as a main material, and the wall thickness is preferably 10mm-12 mm; the inner surface 3 and the outer surface 1 form a wall thickness 2 to prevent the ball from sinking due to external force, and the wall thickness 2 is mainly used for adjusting the weight and elasticity of the ball during manufacturing; the side length of the hole on the outer surface of the hole 4 is preferably 13mm, the side length of the hole on the inner surface of the hole is preferably 12mm, and the hole on the inner surface of the hole is preferably pentagonal and 12 in total; the height of the strip-shaped textures 5 is not more than 1mm, and the strip-shaped textures are used for simulating rattans and increasing friction; the orientation of the stripe 5 and the shape of the hole 4 should be coordinated with each other to naturally form the hole 4 in conformity with the stripe.

The preferred mass of the ball of the present invention is in the range of 160g to 180g, consistent with conventional takraw balls.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
