BACKGROUNDSoccer is the world's most popular sport and the soccer ball is the most important piece of equipment used in the game. Although the color and designs on the outside of a soccer ball may be different, the shape, size, and weight of regulation balls are defined by international rules. During soccer games, a player can impact the ball with their head, either intentionally or inadvertently.
The present disclosure will be more readily understood from a detailed description of some example embodiments taken in conjunction with the following figures:
Various non-limiting embodiments of the present disclosure will now be described to provide an overall understanding of the principles of the structure, function, and use of impact dissipating balls disclosed herein. One or more examples of these non-limiting embodiments are illustrated in the accompanying drawings. Those of ordinary skill in the art will understand that the balls and methods specifically described herein and illustrated in the accompanying drawings are non-limiting embodiments. The features illustrated or described in connection with one non-limiting embodiment may be combined with the features of other non-limiting embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.
The presently disclosed embodiments are generally directed to impact dissipating balls, methods of using impact dissipating balls, and methods of manufacturing impact dissipating balls. More specifically, the presently disclosed embodiments are generally directed to soccer balls that can be constructed with one or more layers, sections, or portions of impact absorbing, impact dissipating materials, or impact dissipating structures/geometries, referred to generally herein as padding or a padding layer. The particular type and/or arrangement or placement of padding can vary based on a variety of factors, such as style of soccer ball, size of soccer ball, the manufacturing process of the soccer ball, expected levels of impact, quality of the soccer ball, regulations with which the ball is intended to comply, and so forth. As described in more detail below, in some embodiments, a soccer ball can be manufactured from multiple layers wrapped or otherwise formed around an airtight bladder or other type of core. In accordance with the present disclosure, padding can be disposed on the outer surface and/or in between various layers during the manufacturing process. This padding can generally serve to dissipate impact to a player when the player strikes the ball, such as using their head. The padding can also serve to dissipate impact when a player is inadvertently hit with the ball, such as in the face or other parts of the head.
In some embodiments, soccer balls incorporating padding satisfy appropriate regulations such as those promulgated by Fédération Internationale de Football Association (FIFA). As such, in some embodiments, soccer balls incorporating padding can be spherical, made of leather or other suitable material, of a circumference of not more than 70 cm and not less than 68 cm, not more than 450 g in weight and not less than 410 g at the start of the match, and a of a pressure equal to 0.6-1.1 atmosphere (600-1100 g/cm2) at sea level. Soccer balls for youth games can have smaller dimensions and weights. As is to be appreciated, impact dissipating balls in accordance with the present disclosure can be utilized for other sporting endeavors, such as sports in which players typically impact the ball with their head. For such sports, such as futsal, the impact dissipating balls can be manufactured with padding while retaining relevant competition ball requirements. With regard to futsal balls incorporating padding during the manufacturing process, for example, the futsal ball can be spherical, made of leather or other suitable material, of a circumference of not less than 62 cm and not more than 64 cm, not less than 400 grams nor more than 440 grams in weight at the start of the match, and of a pressure equal to 0.4-0.6 atmosphere (400-600 g/cm2) at sea level. To the extent that FIFA regulations may vary, or the ball will be used for sports having different requirements, impact dissipating balls can be manufactured in accordance with the present disclosure to comply with those regulations and/or requirements.

The cover 106 can be made from, for example, synthetic leather made from PU (polyurethane) and PVC (poly vinyl chloride). As is to be appreciated, there are many variations of synthetic leather that can be used for cover 106, such as AI-2000, Japanese Teijin Cordley, Microfiber, English Porvair, Korean Ducksung, Leather Art Pakistan Synthetic Leather, and PVC (poly vinyl chloride). The highest quality soccer balls used in competition and by professionals are typically produced by using AI-2000, Cordley, Ducksung, Mircofiber or other types of PU synthetic leather. Promotional soccer balls or practice balls are usually constructed with Polyvinyl Chloride(PVC) or rubber (molded or stitched) covers. For indoor soccer balls, the cover 106 can be made with a felt material similar to what is used on a tennis ball.
The cover 106 can comprise of a plurality of panels, the different segments that make up the outside covering of the ball, having similar or different shapes. The number of panels can vary for each design. A 32-panel ball is an example type of soccer ball, which is essentially a Buckminster Ball consisting of 20 hexagonal (six sided) and 12 pentagonal (five sided) surfaces. Panels of cover 106 can be stitched, glued, or thermally molded, such that when the soccer ball 100 is inflated, it is nearly a perfect sphere. Other traditional designs are 18 and 26-panel constructions, used in various professional leagues, including Major League Soccer, Scottish and English leagues. Some designs use less panels, such as 6 paneled soccer balls that are thermally bonded and do not utilized stitching.
