Description
- 1. Field of the Invention
- The present invention relates to a ball, and more particularly to a sports ball comprising a webbing layer which is capable of enhancing the strength of the sports ball, and allows the roundness thereof to be substantially maintained.
- 2. Description of Related Arts
- A conventional sports ball, such as an American football, usually comprises an inflatable ball bladder, an outer cover, and an inner lining wound on a bottom surface of the outer cover, wherein the outer cover along with the inner lining are fittedly attached on an outer surface of the ball bladder for forming the sports ball having a predetermined strength, elasticity and roundness. The inner lining is meant to provide sound support to the outer cover and maintain the predetermined shape of the sports ball. Occasionally, the sports ball may further comprise a cushion layer attached between the outer cover and the ball bladder for providing additional cushioning effect to the sports ball. When the sports ball is provided with the cushion layer, the player may be able to hold the sports ball easier and when the player hits the ball, he or she may feel more comfortable.
- A disadvantage of this conventional sports ball is that when the cushion layer is added to the sports ball, the attachment between the cushion layer and the ball bladder may not be strong enough so as to render the entire sports ball not durable. Moreover, in order to achieve a predetermined cushioning effect, the cushion layer may be made to have a predetermined thickness (which in many occasions may be too thick) so as to affect the roundness or the curvature of the entire sports ball.
- Another disadvantage of the conventional sports ball is that when the sports ball is embodied as an American football or a basketball, channels are usually formed on the ball bladder so that the outer cover can be attached onto the ball bladder as guided by the channels. As a result, when the inner lining and the cushion layer need to be inserted between the outer layer and the ball bladder, the attachment between any two of them may not be secure enough. As a result, when the conventional sports ball, whether football or basketball, is subject to great impact, there would have high chance that the attachment between the outer layer, the cushion layer, and the ball bladder would be damaged.
- Moreover, when too many layers are attached between the outer cover and the ball bladder, stitching of the outer cover would be difficult so that for those balls which need stitching of the outer cover, the quality of the stitching may be undermined.
- In light of the above, there exists a tension between having many layers attached between the ball bladder and the outer cover for enhancing the comfort and performance of the sports ball on the one hand, and bad quality attachment between the cushioning pad, the inner lining, the outer cover, and the ball bladder.
- A main object of the present invention is to provide a sports ball comprising a webbing layer which is capable of enhancing the strength of the sports ball, preventing the inflatable ball bladder from being over inflated, preserving the desired shaped for the sports ball, and allowing the roundness thereof to be substantially maintained.
- Another object of the present invention is to provide a sports ball comprising a webbing layer integrally embedded within an outer bladder portion layer and an inner bladder portion layer to form a ball bladder of the sports ball. In other words, the webbing layer does not need to be externally attached on the ball bladder so as to substantially enhance the strength of the sports ball while ensuring that there is no or only minimal element attached between the ball bladder and the outer cover. Accordingly, the above-mentioned shortcomings for the conventional sports ball can be avoided.
- Another object of the present invention is to provide a sports ball comprising a webbing layer integrally embedded to form the ball bladder which is capable of being utilized for forming a wide variety of sports ball, such as an American sports ball.
- Another object of the present invention is to provide a sports ball comprising an inflatable bladder which has better flexibility and impact resisting ability as compared with conventional arts.
- Another object of the present invention is to provide a sports ball which can be easily manufactured and does not involved complicated manufacturing process and materials so as to minimize the manufacturing cost of the present invention.
- Another object of the present invention is to provide a method of manufacturing a sports ball comprising a webbing layer, which is capable of enhancing the strength of the sports ball, and allows the roundness thereof to be substantially maintained.
- Accordingly, in order to accomplish the above objects, the present invention provides a sports ball, comprising:
- a ball cover having a ball cavity and a valve hole communicating thereto;
- an inflatable ball bladder, which is disposed in the ball cavity of the ball cover and is adapted to be inflated through the valve hole to support the ball cover; comprising:
- an outer bladder portion layer;
- an inner bladder portion layer disposed the outer bladder portion layer; and
- a webbing layer disposed between the inner and outer bladder portion layers, wherein the inner and outer bladder portion layers are treated to integrally embed the webbing layer therebetween to enhance a strength of the ball bladder such that the webbing layer allows the ball bladder to be fully inflated for evenly distributing air pressure therein to support the ball cover.
- Moreover, the present invention provides a method of manufacturing a sports ball, comprising the steps of:
- (a) forming a ball cover having a ball cavity and a valve hole communicating thereto;
- (b) providing an outer bladder portion layer and an inner bladder portion layer;
- (c) forming a webbing layer around the inner bladder portion layer, wherein the inner bladder portion layer is disposed in the outer bladder portion layer to retain the webbing layer between the inner and outer bladder portion layers;
- (d) treating the inner and outer bladder portion layers to integrally embed the webbing layer therebetween to form an integrated inflatable ball bladder, such that the webbing layer allows the ball bladder to be fully inflated for evenly distributing air pressure therein; and
- (e) disposing the ball bladder in the ball cavity of the ball cover, wherein when the ball bladder is inflated, the ball cover is supported by the ball bladder.

It is worth to mention that thewebbing layer 23 prevents theball bladder 20 to be over inflated as well. - According to the preferred embodiment of the present invention, the
ball cover 10 is preferably made of leather or rubber materials, such as PVC, for providing a preliminary protection to theinflatable ball bladder 20. Moreover, theball cover 10 is preferably dyed with predetermined graphical patterns for enhancing an aesthetic appeal to the sports ball for use in specified circumstances. - The
outer bladder portion 21 and theinner bladder portion 22 are made of rubber materials such as PVC for embedding thewebbing layer 23 between theouter bladder portion 21 and theinner bladder portion 22. Both theouter bladder portion 21 and theinner bladder portion 22 are preferably shaped and crafted to have a streamlined shape suiting a typical shape of an American football. It is worth mentioning, however, that the shape of theouter bladder portion 21 and theinner bladder portion 22 may also be formed as having a spherical shape so as to suit a wide variety of ball types, such as a basketball. - As a result, when the inner and
outer bladder portions outer bladder portions webbing layer 23 within the single layer, wherein the single layer is flexible to sustain impact exerted on the sports ball of the present invention, as shown inFIG. 3 of the drawings. Moreover, since the inner and theouter bladder portion webbing layer 23 in between, a thickness of theball bladder 20 is less than that of a conventional ball bladder, yet having an enhanced flexibility and strength. - In addition, the
inflatable ball bladder 20 further comprises a plurality of attachingchannels 24 spacedly formed on theouter bladder portion 21 for guiding attachment between theinflatable ball bladder 20 and theball cover 10. Each of the attachingchannels 24 is preferably embodied as an elongated member integrally extended on theouter ball bladder 21 to divide the entire surface area thereof into a corresponding number of carcass areas, wherein each of the carcass areas are arranged to be attached by theball cover 10 for sealingly and fittedly covering theball bladder 20. - Accordingly, the
ball cover 10 comprises a plurality ofcarcass panels 13 each of which is shaped and sized corresponding to a shape and size of the corresponding carcass area, such that thecarcass panels 13 are adapted to be attached on the carcass areas respectively on theouter ball bladder 21. In other words, the present invention is suitable for being manufactured as a ball type which typically employs the attachingchannels 24, such as American footballs and basketballs. However, it is important to stress that the present invention can also be utilized for manufacturing, say, a soccer ball. - The
webbing layer 23 comprises a plurality ofwebbing elements 231 attached on an outer surface of theinner ball bladder 22 of theinflatable ball bladder 20 for being embedded between theouter ball bladder 21 and theinner ball bladder 22, wherein thewebbing elements 231 are interwoven with each other to form a substantially seamless web ofwebbing layer 23 to strengthen theinflatable ball bladder 20 while eliminating the need for the sports ball of the present invention having a cushion pad. - More particularly, the
inner ball bladder 22 is entirely embraced by thewebbing layer 23, wherein each of thewebbing elements 231 is embodied as an elongated strengthening thread, such as a nylon thread, evenly and repetitively wound around the outer surface of theinner ball bladder 22, so that the strengthened threads are overlapped with each other to form the seamless webbing layer 23 (a web structure). - In order to enable the strengthened thread being permanently affixed on the outer surface of the inner
bladder portion ball 21, before winding thereon, the strengthened threads are coated with glue for adhering to the outer surface of theinner ball bladder 22 and with each other. Moreover, theinflatable ball bladder 20 with the adhering strengthened thread affixed thereon are together cured by heating in a mold, so that the strengthened threads will be hardened to form thewebbing layer 23 which is permanently united with theinner ball bladder 22 integrally. Thus, theouter ball bladder 21 and theinner ball bladder 22 are heated treated along with thewebbing layer 23 so as to integrally unite theinner ball bladder 22, theouter ball bladder 21 and thewebbing layer 23. - Just like the fishing net structure or the spider web structure, the web structure is one the most strengthened and rigid constructions, that can support high stress and resist high impact force. Thus, the
webbing layer 23 highly reinforces the inner and theouter bladder portion inflatable ball bladder 20 of the present invention is strengthened by thewebbing layer 23 and has a better flexibility and impact resisting ability. - One may appreciate that the sports ball of the present invention then has an optimal strength so that the ball cover 10 only facilitate aesthetical functions. As a result, it can be dyed with a wide variety of graphical patterns and the
carcass panels 13 needs to be attached onto theouter ball bladder 22 of theinflatable ball bladder 20. It is worth mentioning, however, that a cushioning pad can nevertheless be attached between theinflatable ball bladder 20 and the ball cover 10 for providing additional cushioning effect to the sports ball, yet it is important to stress that the cushioning pad is indeed optional. - Referring to
