Problems solved by technology

One limitation of current inflatable technology is that the inflatable air bladder may lose pressure after a period of time due to air loss, which may occur by seepage from valves, or by migration of the filled air across the air bladder membrane, or otherwise.
Any physical damage that pierces the bladder, even small holes or tears may result in loss of pressure and even the inabil

Embodiment Construction

[0016]This detailed description is provided for amplifying the invention and aiding in understanding of the disclosure, by reference to a possible embodiment(s). The invention shall not be interpreted as limited to any particular embodiment shown, except as set forth in the claims.

[0017]A sports ball 5, such as for use where inflatables are typically employed, is disclosed herein, FIGS. 1A through 1D show various embodiments of the sports ball 5, in the form of a basketball, a football, a volleyball or a soccer ball. While these particular embodiments are shown for illustrative purposes and each is certainly within the scope of the invention, balls for other sports and general play are also within the scope. In a central aspect of the sports ball 5 is its core 15.

[0018]The core 15 may comprise a foam, such as polyurethane (“PU”), EVA, or other foamed structure. Other materials with resiliency, such as rubbers, may also be used. In one embodiment, the PU foam is open cell PU foam whe...

Abstract

In some aspects, the invention relates to a inflation independent sports ball comprising a foam core 15 and an outer covering 10, wherein the sports ball is selected from the group consisting of a football, a basketball, a volleyball and a soccer ball, wherein the sports ball 5 is devoid of an inflatable air bladder. In other aspects, the invention relates to a sports ball having a diameter and comprising a synthetic leather outer covering 10 at least partially covering a polyurethane foam core 15, wherein the foam core further comprises at least one internal compartment and a cylindrical body spanning at least part of the length of the diameter of the sports ball. In other aspects, the invention relates to a sports ball having an outer covering and a foam core, wherein the foam core 15 is not filled with foam entirely throughout its internal volume, but rather includes space for air.

Description

FIELD OF THE INVENTION[0001]The invention relates generally to sports balls, such as basketballs, footballs, volleyballs and soccer balls.BACKGROUND ART[0002]Sports balls of the type traditionally inflated (e.g., basketballs, footballs, volleyballs and soccer balls) are well known in the art and are sometimes referred to as “inflatables.” For example, basketballs are generally manufactured to include an inflatable air bladder surrounded by an outer covering of cover panels. Other inflatable sports balls such as volleyballs, soccer balls and footballs also feature the well-known inflatable air bladder (often comprising rubber, such as 80% butyl rubber and 20% natural rubber) and various other outer coverings. One limitation of current inflatable technology is that the inflatable air bladder may lose pressure after a period of time due to air loss, which may occur by seepage from valves, or by migration of the filled air across the air bladder membrane, or otherwise. When pressure los...
