DESCRIPTION OF THE PREFERRED EMBODIMENT

[0034] With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved medallion gameball embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

[0035] The gameball 10 includes an exterior surface. The medallion gameball comprises a medallion disposed within an aperture in the gameball exterior surface and substantially flush with, or recessed below, the gameball exterior surface. The medallion of FIG. 1 is shown as being oval, however the medallion may have any shape, for example it may be circular or polygonal. The medallion is fabricated of a rigid or semi-rigid polymeric material with indicia 36 therein. The indicia can take on many forms. The indicia can include text or pictures. The indicia can be a hologram. The indicia can comprise a thermochromic material that changes appearance with changes in temperature. The indicia can comprise a photochromic material that changes appearance with changes in lighting. A layer of conventional transparent polymeric material, for example urethane, is formed over the indicia 36. The transparent polymeric material forms an exterior surface 34 of the medallion and functions to protect the indicia during use of the gameball.

[0036] For ease of understanding and clarity of description, the inventive medallion gameball is below described in its application to basketballs. It should be understood that the invention herein is equally applicable to other gameballs such as, for example, golf balls, softballs, baseballs, soccer balls, volleyballs, footballs, rugby balls and tennis balls.

[0037] The central component of the medallion basketball is a bladder 12. Such bladder is preferably fabricated of an air impervious elastomeric material in a spherical configuration. The preferred material is a vulcanized butyl rubber compound, such as, for example, Exxon Butyl 065 or Polysar Butyl 100. Such bladder is wrapped with strands 16. Such strands are of essentially inelastic material, preferably nylon or polyester multi-filament strands wrapped around the bladder in random configuration to maintain the size and shape of the ball when inflated and during use.

[0038] A carcass 22 is formed over the windings. Such carcass is fabricated of a rubber compound molded over the wound bladder. Natural rubber cis polyisoprene) is preferred for improved rebound and abrasion resistance. A mixture of rubbers may also be used, such as natural rubber and styrene butadiene rubber. Such carcass has an oval rib 24. Such rib has a thickness of between about 0.2 and 2.0 millimeters, preferably about 1.0 millimeters. In addition, a plurality of supplemental ribs 26 are provided. Such ribs have a thickness of between about 0.2 and 2.0 millimeters, preferably about 1.0 millimeters extending outwardly away from the carcass.

[0039] The carcass is molded to include a recess 18. The recess is formed as an oval in the exterior surface of the carcass. The recess area has a depth of between about 0.5 and 3.5 millimeters, preferably 2.0 millimeters. The major axis of the oval constitutes between 3 and 20 percent, preferably about 8.5 percent, of the circumference of the carcass.

[0040] The basketball 10 also comprises a plurality of panels 28, preferably leather, coupled to the exterior surface of the carcass between the supplemental ribs. Such panels may be of a natural leather or of a synthetic leather. These panels have a thickness of between about 0.2 and 2.0 millimeters, preferably about 1.0 millimeters. An oval aperture 30 is formed in one of the panels to expose the recess in the carcass and the oval rib.

[0041] Finally, the medallion basketball comprises a medallion 32 positionable on the carcass in a central region of the recess. The medallion is preferably secured in position by a pressure sensitive adhesive or a flexible cross-linked urethane adhesive.

[0042] Other adhesives are also suitable for use in securing the medallion to the carcass. One such adhesive is a pressure sensitive hot melt adhesive, such as PL919 offered by SIA Adhesives, Incorporated of Chicago, Ill. In the preferred embodiment, a layer of between 0.005″ and 0.015″ is applied to the back of the medallion. Subsequently, both the medallion and the ball are heated. The goal of such heating is to bring the adhesive to about 250 degrees Fahrenheit. After heated the medallion is pressed into position in such a manner that intimate contact between the ball and medallion is achieved. To this end, a contoured tool may be utilized. Upon cooling, the medallion is secured to the carcass.

[0043] A second possible adhesive is a pressure sensitive adhesive. One such pressure sensitive adhesive is a system from 3M which employs a #300LSE high strength acrylic adhesive and 9671LE and 9672LE laminating adhesives. In utilizing such a system, heat is not required to activate the adhesive, but is helpful in ensuring proper contact between the carcass and medallion.

[0044] A contact adhesive is yet another alternative. A suitable contact adhesive is 3M's 1357 contact adhesive. In utilizing this alternative, the contact adhesive is applied to both the ball and medallion. The solvent contained in the adhesive is then allowed to flash, thereby removing the solvent from the adhesive and increasing its tackiness. Optionally, a second layer of adhesive can then be applied. The medallion and carcass are then brought into contact. After 24 hours a full strength bond is achieved. In all of the above described adhesive alternatives, cleaning the bonded surfaces before adhesive application results in superior results. Alcohol, or other suitable solvents, can be employed in cleaning the surfaces. Additionally, adhesive promoters or primers can be used. An example of a suitable primer is Lord Corporation's Chemlock 77707 primer.

[0045] In another embodiment the medallion 52 incorporates a flange 54. Such flange 54 is integral with the periphery of the medallion 52 and is used in securing the medallion 52 in place. More specifically, the flange 54 is covered by one or more of the plurality of panels of the ball. In this manner, the flanged medallion 52 provides for increased securement between the medallion 52 and ball. Naturally, the adhesive may also be used to additionally secure the medallion to the gameball. In the preferred embodiment the flange 54 is between ⅛″ to ¼″ in width and is formed about the entire perimeter of the medallion 52. In an alternative embodiment, the flange 54 is scalloped is reduce wrinkling once secured to the ball. The flange 54, however, is not covered with the urethane dome, as is the center of the medallion 52. Additionally, the upper panel 56 of the ball includes a cut out 58 sized to expose the center of the medallion 52, but not the flange 54. Namely, when secured the laminated panel 56 covers the flange 54 but not the urethane dome. In this manner only the dome portion of the medallion 52 containing the indicia 36 is visible.

[0046] The preferred thickness of the medallion 52 is about 0.05″ with a manufacturing tolerance on thickness of about +/−0.10. Such a thickness enables the surface of the medallion 52 to be flush with the remainder of the surface of the gameball. The medallion 52 can be formed into a variety of shapes. Nonetheless, the preferred medallion 52 has major diameters of 1.5″ and 2.6″. An alternative size employs diameters of 1.3″ and 2.4″. The size and shape of the medallion 52 is, in part, dependent upon the type of ball upon which it is employed. For example, the medallions of the present invention can be affixed to other types of inflated balls, including soccer balls, volleyballs and footballs. An example of a volleyball employing the flanged medallion 52 is illustrated in FIG. 11.

[0047] An alternative embodiment of the invention is shown in FIGS. 7 and 8. In such embodiment, the panels 38 are formed integral with the carcass. Such panels are preferably formed with a surface to simulate the appearance and feel of natural leather. In such embodiment one panel includes a recess 40 molded therein to a depth equal to the depth of the carcass between the ribs where the medallion is received as in the primary embodiment as discussed above and with a medallion discussed above. This allows for a less costly fabrication then would occur with the previously described embodiment wherein the separate leather panels are individually coupled to the carcass.

[0048] In another embodiment the medallion is incorporated in a non-spherical gameball such as an American football. The football comprises a layer of bladder material such as the previously described butyl rubber or a polyurethane material. A reinforcing lining is located immediately over the bladder, and immediately over the lining, a leather cover is situated. A lining is employed to help the ball retain the proper shape and to provide additional strength and mechanical reinforcing to the cover material. Significant amounts of stress and strain are imposed on the cover by the forces generated by the inflated bladder. Typically, the ball is inflated to about 12-15 psi and much of this force is imposed on the leather cover. Overstress conditions can be imposed through kicking, bouncing, and the rough handling that a ball typically receives while in play. The lining helps the ball maintain shape and structural integrity in the face of these conditions. The cover material is formed of synthetic leather or natural leather panels that have been tanned. The football cover includes a seam where panels of the leather cover of the ball meet and are sewn together. Apertures formed in the cover of the ball allow the passage of lacings that seal an opening in the cover through which the bladder and liner are inserted. One panel includes an aperture in which a medallion is disposed. The medallion may be secured in place mechanically with a flange or by adhesive as previously described. The thickness of the medallion is controlled so that the exterior of the medallion is preferably flush with the exterior of the leather panel.

[0049] In other embodiments the medallion is incorporated between the core and cover of other gameballs. For example, the medallion may be incorporated between the cork and winding core and leather cover of a softball or baseball in similar fashion to that described above. Alternatively, the medallion may be incorporated between the core and cover of a golf ball or tennis ball. In any embodiment it is preferred that the medallion fit within an aperture in the cover so that the exterior of the medallion is substantially flush with the exterior surface of the gameball.

[0050] As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

[0051] Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to falling within the scope of the invention.
