20080268989 | Sports ball - New designs for a sports ball comprising at least two polygonal panels and having an improved performance and uniformity. Each panel has doubly-curved edges that curve along and across the surface of the sphere. The panels are p-sided curved polygons, where p is an integer greater than 1. The single panels, in an imagined flattened state, have curved edges where each edge curves inwards, outwards or undulates in a wave-like manner. The edges are arranged so each individual panel is without mirror-symmetry and the edge curvatures are adjusted so the panel shape can be varied to achieve more uniform panel stiffness as well as economy in manufacturing. The ball also has a possible shape-induced spin due to the panel design and the overall rotational symmetry of the design. In various embodiments, the ball comprises at least two multi-paneled layers that are topological duals of each other, wherein each layer provides a compensatory function with respect to the other layer such that the ball has a uniformly performing surface. Applications include but are not limited to designs for soccer balls, baseballs, basketballs, tennis balls, rugby, and other sports or recreational play. The shape of the ball can be spherical, ellipsoidal or other curved convex shapes. | 10-30-2008 |
20100184542 | STRUCTURE OF BALL - A ball includes a core and a surface cover that is formed by sewing together two shape-mated covering pieces. Each covering piece has a close-to-edge area defining inboards an inward circumferential zone in which spaced through apertures are defined. The through apertures are circumferentially distributed along the inward circumference of the close-to-edge area. The close-to-edge area has an outward circumference forming a turn-back section. The turn-back section is foldable over and attached to itself by adhesives so as to form a smooth and regular outer circumference of the covering piece. When the surface cover of the ball is completely sewn, a sewn portion between the two covering pieces shows a smooth and regular configuration so that no secondary finishing of the sewn portion of the covering pieces is needed. The manufacturing time of the ball can thus be shortened and the manufacturing costs reduced. | 07-22-2010 |
20110118063 | INSTRUCTIONAL BASEBALL - An instructional ball having an inner core, an outer core is an ellipsoid, and an outer cover. The instructional ball has an ellipsoid shape, a longitudinal axis, and a generally circular transverse cross-section along a transverse axis. | 05-19-2011 |
20130210565 | BASEBALL OR SOFTBALL AND COVER FORMING METHOD THEREOF - A cover method for baseballs or softballs, whereby a spherical core is independently formed and a fiber material layer is attached, this fiber material layer is evenly brushed with a thin layer of PU, and this spherical core is then placed in a mold, and PU is injected into the mold to cover the spherical core and heated, finally the mold is removed to reveal the complete ball. Utilizing this method and mold to produce the ball covers for baseballs and softballs, whereby PU is brushed onto, and penetrates into, the fiber material layer on the independently formed spherical core, so that when the ball cover forms, the ball cover and spherical core attaches and fits firmly, and the porous construction of this fiber material cover attracts air, and therefore greatly avoids bubbles forming when the ball cover is formed which affects the quality and lifespan of the balls. | 08-15-2013 |
20140080643 | LEAK-FREE AMERICAN FOOTBALL - Provided is a leak-free American football, which has a polyurethane foam having a shape of an American football; a covering formed on an exterior surface of the polyurethane foam and having a seam; multiple pairs of lacing holes formed in the covering along two opposite sides of the seam, and a lace passing through the multiple pairs of the lacing holes to close the seam, such that the polyurethane foam is covered by the covering and the lace. Since the polyurethane foam is solid and elastic, the leak-free American football can maintain a desired size, shape and bounce without the need for inflation, thereby improving the stability and durability. | 03-20-2014 |
20140342859 | PROTECTIVE COVER FOR MEDICINE BALL AND METHODS OF MAKING THEREOF - A removable protective ball cover for a medicine ball is provided to protect an outer surface of the ball from wear and tear, increase the grip of the surface of the ball and maintain the balls' shape and structure. The ball cover may be formed from a durable material with high surface tension formed into a spherical shape with an opening that is used to encapsulate the medicine ball within the ball cover. The opening may be cinched closed by lacing the opening together to substantially, if not completely, cover the medicine ball and create a tight fit around the ball that will not move in relation to the ball. The ball cover may be formed from a series of specially-shaped panels which are triple stitched together with a backing material to prevent breaking of the cover. | 11-20-2014 |
20160067576 | Baseball Training Aid - The present invention provides a baseball training aid that includes a ball having a core and an outer layer. The outer layer includes a pair of panels that are sewn together at its seams via stitching. The pair of panels is provided in a first color, wherein the seams and stitching are provided in a second color that contrasts with the color of the pair of panels. The seams are configured to be brightly colored to allow a user to better track the rotation and spin of a ball. Further, the stitching is also configured to be brightly colored to visually enhance the rotation and spin of the ball. In this way, the user can learn to recognize the rotation of a ball to increase the probability of hitting or catching the ball. | 03-10-2016 |
473599000 | For distensible bladder (e.g., casing of football, etc.) | 8 |
20080242458 | Street Soccer Ball - A novel street soccer ball having a carcass of a tough, durable material for improved wear on hard surfaces and a filler material to reduce and deaden the bounce of the soccer ball is disclosed. The inflatable bladder is similar to bladders used in many sports balls and is inflatable to provide adequate performance and feel to the soccer ball. Inside the inflatable bladder, a stuffing or filler material is included that deadens the bounce of the soccer ball to improve play of the soccer ball on hard surfaces such as asphalt, concrete, or dirt. While the stuffing or filler material is located inside the inflatable bladder, the air pressure of the bladder is the primary contributor to the shape and feel of the ball, and the stuffing or filler material primarily contributes to deadening the ball's bounce. | 10-02-2008 |
