Definitions

  • the invention relates generally to sports balls, such as basketballs, footballs, volleyballs and soccer balls,
  • Sports balls of the type traditionally inflated are well known in the art and are sometimes referred to as "inflatables.”
  • 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 loss occurs, the inflatable must be re-inflated by some mechanism, such as a pump. Any physical damage that pierces the bladder, even small holes or tears may result in loss of pressure and even the inability to be re-pressurized.
  • Foam balls such as NERF® brand balls
  • foam balls to date have exhibited substantially different playing characteristics and feel that traditional sports balls, and do not comport with or approximate the standards set by sports organizations for regulation play, such as size, rebound response, weight or other characteristics.
  • a sports ball 5 with a core 15 and outer covering 10 that does not include an air bladder and that comports with the standards set by sports organizations for regulation play, such as size, rebound response, weight, or other characteristics is desirable.
  • a sports ball 5 is disclosed herein.
  • 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.
  • 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.
  • 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.
  • 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.
  • a central aspect of the sports ball 5 is its core 15.
  • the core 15 may comprise a foam, such as polyurethane ("PU"), EVA, or other foamed structure.
  • PU foam is open cell PU foam wherein the cell walls comprising the foam are broken and the air or other gasses may freely enter and exit the broken cells.
  • the PU foam is closed cell foam wherein the cells comprising the foam are not broken and air or other gases are "trapped" within the intact cells comprising the foam.
  • the PU foam core may comprise both open and closed cell foam.
  • Other foams such as foamed natural rubber or soy bean based foams should be considered within the scope of this disclosure.
  • the core 15 may comprise PU foam of a single density.
  • the density of the PU core 15 may be constant, or nearly constant throughout the circumference of the core 15.
  • the density of the PU foam core 15 may change through the diameter of the core 15.
  • the embodiment shown in Figure 2 shows the density of the PU foam core 15 increasing near the center of the core 15 - i.e., the density of the PU foam near the center of the core 15 is greater than the density of the PU core near the exterior surface of the core 15.
  • the density of the PU foam near the center of the core 15 could be less than the density of the PU foam near the outer surface of the core 15.
  • the core 15 may comprise a "constant" density gradient (i.e., density increasing at a generally constant rate from the outer surface to the center or vice versa), a “step wise” density gradient (i.e., the density increases (or decreases), in discrete “steps” from the outer surface to the center), a combination of the forgoing, or many other conceivable density gradient (such as a "peak” gradient wherein the density of the PU increases from the outer surface of the core 15 to a point in the interior and then begins to decrease again closer to the center of the core 15 ). Any possible density gradient should be considered within the scope of this disclosure.
  • the core 15 may comprise a plurality of concentric layers 16a, 16b, 16c, 16d, 16e, 16f.
  • the concentric layers 16a, 16b, 16c, 16d, 16e, 16f may comprise single discrete densities of PU foam or they comprise multiple densities of PU foam in either a constant, step wise or peak gradient constructions.
  • the densities of the PU foam in the concentric layers 16a, 16b, 16c, 16d, 16e, 16f increases near the center of the core 15, alternatively the densities of the PU foam in the concentric layers 16a, 16b, 16c, 16d, 16e, 16f may decrease near the center of the core 15, alternatively, a peak gradient design or other construction may be used.
  • the concentric layers 16a, 16b, 16c, 16d, 16e, 16f may have the same or approximately the same thickness while in other embodiments the concentric layers 16a, 16b, 16c, 16d, 16e, 16f may be of varying thicknesses.
  • the core 15 is not filled with foam entirely throughout its internal volume, but rather includes space for air.
  • the space could be configured as a single air cavity, akin to the common single central bladder of known inflatables.
  • sports ball 5 need not be configured to rely on air pressure to provide the desired rebound, firmness, resistance to compression, or other desired characteristics that are typically controlled by the level of inflation of a traditional inflatable.
  • sports ball 5 will in many configurations not have an inflation valve at all. While it is possible to configure the sports ball 5 as disclosed in the present disclosure such that the air in the cavity is pressurized, such pressure is not critical for maintaining form and rebound within acceptable levels in every embodiment.
  • the cavity may be pressurized at the time of production.
  • the sports ball 5 may be constructed with disregard to the air pressure in the cavity, or with the intent or anticipation that the air pressure in the cavity be approximately the ambient air pressure. With the added structural integrity of the sports ball 5 as taught herein compared to traditional inflatables, some embodiments may even exhibit an air pressure in the cavity intentionally lower than that of the ambient atmospheric conditions. Using such a "negative pressure" configuration may permit the sports ball 5 to have a tighter feel normally attributable to the outward pressure of a traditional inflatable.
  • the outer boundary 20 will be thicker than would be, for example, the bladder, winding, and covering of a basketball. In some embodiments, this outer boundary 20 will be between one (1) centimeter and one (1) inch (2.54 cm) thick.
  • the structural integrity of the sports ball 5 may be enhanced by incorporating struts or other structures within the cavity space, such as spines that extend outwardly from the center, or from a center mass (such that if the outer boundary 20 were removed, the struts may look like a starburst, for example).
  • Other, more elaborate internal structures can be employed, such as grid patterns, scaffolding, internal ribbing about the inner circumference of the outer boundary 20 and any other structure that may enhance the ability of the sports ball 5 to maintain its round configuration even in the absence of an internal air pressure higher than ambient air pressure.
  • the core 15 may comprise a plurality of internal compartments 25 in which the air of one compartment 25 does not flow freely to another compartment 25.
  • Compartments 25 are separated by walls such as the ribs 30 shown in Figures 5 and 6 , and may be oriented and configured in various shapes and spatial relationships.
  • the compartments 25 may be arranged like the internal lobes of an orange, such that in cross-section the ribs 30 have the appearance of a wheel-and-spokes.
  • the compartments 25 may be configured loosely on a spiral configuration.
  • the shown embodiment at Figures 5 and 6 depicts compartments 25 near the outer surface of the sports ball 5, separated in circumferential direction by a plurality of walls forming ribs 30.
  • the sports ball 5 Toward the center of the core 15 , the sports ball 5 possesses another cavity disposed inwardly of the circumferentially-disposed compartments 25, denominated in the figures as a central cavity 35.
  • the central cavity 35 is a cylindrical body extending from the outer boundary 25 on one side of the sports ball 5 to the outer boundary 25 on the other side.
  • central cavity 35 might be a perfectly round cavity concentric with the center of the sports ball 5, or it might be a spheroid, such as a prolate spheroid.
  • the internal compartments 25 may be configured and placed relative to one another such that in any rotational position of the sports ball 5 a cross section taken through its center will look the same as the cross section taken if the ball is rotated 90 degrees.
  • the core 15 may comprise a plurality of concentric layers of internal compartments 25 arranged around a single central cavity 35. In other configurations, including the one shown in Figures 5 and 6 , the cross section taken at different rotational positions will look markedly different.
  • the core 15 may comprise a plurality of central cavities 35, which need not be concentric to the center of the sports ball 5.
  • the internal compartments 25 are evenly spaced around the cylindrical body 35, but the cross section taken at different rotational positions will look different.
  • struts and other structures as discussed above in connection with a single cavity may also be used. It will be recognized that the ribs 30 will provide certain structural support similar to that provided by struts and other structures. It may nevertheless be desirable to incorporate additional structural support, perhaps incorporating struts and the like inside one or more of the compartments 25.
  • the internal compartments 25 are generally trapezoidal in shape and are formed by the outer boundary 20 of the core 15, two (2) ribs 30 and the internal cylinder wall 45. Other shapes for the internal compartments 25, including square, rectangular and circular internal compartments 25 should be considered within the scope of this disclosure.
  • the internal compartments 25 may be exterior to the cylindrical body 35.
  • the core 15 comprises between two (2) and eight (8) internal compartments 25.
  • the core 15 may comprise between nine (9) and sixteen (16) internal compartments.
  • the core 15 comprises between seventeen (17) and thirty two (32) internal compartments and finally in yet another embodiment, the core 15 comprises between thirty three (33) and one hundred (100) internal compartments.
  • the material comprising the walls of the compartments 25 may be a porous material, such as open-cell foam. If the material is so porous that air would otherwise move freely among the compartments 25, the compartments 25 may have a material (possibly in the form of a coating or a paint) applied to the interior surface of the internal compartments 25 that reduces or prevents air (or other gases) from migrating across or escaping from the internal compartments 25. In one embodiment the material may be an additional PU coating or film. In an alternate embodiment, the composition of the PU foam forming the internal compartments 25, ribs 30 and internal cylinder wall 45 may be adjusted to prevent air (or other gases) from escaping the internal compartments 25.
  • non-porous materials including closed cell foam, may be used to prevent the free movement of air among compartments 25.
  • a closed cell PU foam may be used to form the 25, ribs 30 and internal cylinder wall 45.
  • the internal compartments 25 may create greater rebound via the compression and expansion of the air trapped inside the internal compartments 25 as the sports ball 5 contacts a surface (i.e., as the ball is bounced on the floor).
  • the core 15 comprises a cylindrical central cavity 35 defined at least in part by the internal cylinder wall 45.
  • the cylindrical body 35 may span the entire diameter of the sports ball 5 terminating against the outer boundary 20 of the core 15 or against the outer covering 10. In an alternate embodiment, the cylindrical body 35 may span only part of the diameter of the core 15. Without being bound by this theory, it is believed that in an embodiment such as this with a central cavity 35, the compression and expansion of the air trapped inside the cylindrical body 35 as the sports ball 5 contacts a surface (i.e., as the ball is bounced on the floor) may create a more controlled rebound.
  • the sports ball 5 may also comprise an outer covering 10, whether the core 15 includes a cavity or not.
  • the outer covering 10 is the primary contact surface when a player handles the sports ball 5.
  • the outer covering 10 fully encases the core 15.
  • the outer covering 10 does not fully encase the core 15.
  • the outer covering 10 may comprise one or more cover panels 11, with groves, lines, or other gaps between the cover panels 11, permitting the core 15 to be seen or touched.
  • an additional material may be inserted between the cover panels 11.
  • the additional material may provide tactile feedback to a player allowing the player to determine the position or orientation of the sports ball 5 in relation to the player's hand.
  • the outer covering 10 may be configured to comprise the features of a football, volleyball, basketball or soccer ball.
  • the outer covering 10 may comprise a plurality of cover panels 11 which are adjacent to channels 12 as shown in Figure 1A .
  • the outer covering may comprise a plurality of cover panels 11 which are adjacent to channels 12 as well as laces 13 as shown in Figure IB.
  • the outer covering 10 may comprise a plurality of pentagonal cover panels 11 as shown in Figure 1C .
  • the outer covering 10 may comprise a series of covering panels 11 as shown in Figure ID.
  • the physical appearance of the outer covering 10 may be configured to include logos, one or more colors or other aesthetic concerns in other embodiments. Additionally, the outer covering 10 may comprise pebbling or other features to aid the player in griping and manipulating the sports ball 5. In one embodiment, the outer covering 10 may be painted or coated to improve its durability. In an alternate embodiment, the outer covering 10 may be painted with a PU paint or a vulcanized rubber material. The vulcanized rubber material may comprise pebbling or other features.
  • the outer covering 10 may be affixed to the core 15.
  • the outer covering 10 may be affixed to the core 15 by any method known to one of ordinary skill in the art.
  • the outer covering 10 may be glued to the core 15 at least partially by an adhesive such as styrene butadiene, acrylonitrile butadiene or a two (2) part urethane.
  • the outer covering 10 may not be attached to the core 15 and in this embodiment the core may "float" inside of the outer covering 10 if desirable.
  • the sports ball 5 may also comprise one or more additional layers of material between the outer covering 10 and the core 15.
  • an additional layer of windings comprised of a natural or synthetic thread may be present between the outer covering 10 and the core 15.
  • the outer covering 10 may be manufactured from any material that is suitable to one of ordinary skill in the art and may comprise leather, synthetic leather, rubber or other synthetic materials. Additionally, the outer covering 10 may be manufactured from differing materials based upon the sports ball 5 being constructed. For example, the outer covering 10 for a football may comprise differing materials than the outer covering 10 for volleyball. In one embodiment, the outer covering 10 may additionally comprise a tuftane thermoplastic polyurethane film.
  • the outer covering 10 is between 0.1 mm and 2.0 mm in thickness. In an alternate embodiment, the outer covering 10 is between 0.8 and 1.25 mm in thickness.
  • the sports ball 5 disclosed herein may be manufactured by any means known to be suitable to those of ordinary skill in the art.
