Problems solved by technology

Although the inner layer of the ball can help prevent the ball from collapsing to a certain extent, if there is too little air pressure in the ball or too little air is pumped into the ball, the ball can easily collapse into an irregular shape
[0011] Also, even when one chooses to pump traditional sewn balls so hard that they have a nice spherical curvature, the joint edges of the surface nubs may crack due to the inability to withstand the enormous air pressure
From the above, it can be seen that a ball with sufficient curvature may lack softness, while a ball with moderate softness may lack sufficient curvature

Embodiment Construction

[0069] see figure 2 and image 3 According to the first preferred embodiment of the present invention, the sewn-on ball 10 of the present invention, for example, a basketball, a volleyball or a football, comprises a spherical surface 11 and an inflatable airbag 20 . The spherical surface layer is formed by sewing a plurality of small surface layer pieces edge-to-edge, wherein an air-filling hole 110 is provided on one surface layer small piece. An inflatable airbag 20 is located inside the spherical surface 11, and the inflatable airbag 20 is further provided with an inflation port 21 extending therefrom to an inflation hole 110 of the spherical surface.

[0070] The sewn-on ball 10 of the present invention further includes a middle bag 30 . The central ball bag 30 is located within the spherical surface layer 11 and surrounds the inflatable airbag 20 to maintain the spherical curvature of the inflatable airbag 20 after inflation. The central ball bag 30 and the inflatable ...

Abstract

The present invention relates to a sewed ball with built-in ball bag. Said ball is formed from a ball surface layer and a ball bag internal bladder placed in the interior of ball surface layer. Said ball bag internal bladder includes an inflatable air bag with an inflatable hole, a built-in ball bag which has a receiving space for receiving said inflatable air bag and a movable air hole from which the inflatable hole can be passed through and extended outward. Said ball surface layer can be used for receiving said ball bag internal bladder, after said ball bag internal bladder is inflated, said ball surface layer can be expanded and formed into a ball with a certain radian and flexibility. Said invention also provides its sewing method.

Description

(1) Technical field: [0001] The present invention relates to a leather ball, especially a sewn ball with a built-in center pocket, wherein the center pocket can increase the surface curvature of the ball without reducing its softness. (two) background technology: [0002] A traditional sewn-on ball usually includes a spherical surface, an inner layer and an inflatable airbag. The inflatable air bag is located in the inner inner layer, and can be used to strengthen the spherical surface layer after being inflated. The spherical surface of a traditional sewn ball is usually sewn from multiple small pieces of the surface made of vinyl chloride or polyurethane. Inflatable bladders are usually made of ordinary elephant rubber, making them resistant to high-pressure pumped air and durable. [0003] The manufacturing method of traditional sewing formula ball comprises the following steps: [0004] (1) cutting the surface layer of each small piece into the same shape; [0005] (...
