| 82 | SKIN MATERIAL FOR BALL AND BALL | EP04721360.8 | 2004-03-17 | EP1604710B1 | 2009-02-18 | MIMURA, Masahisa c/o Teijin Cordley Limited; TAKAHASHI, Shogo c/o Teijin Cordley Limited |
| A skin material for balls which is a sheet-form material comprising a base layer and formed on one side thereof a coating layer made of a polymeric elastomer, characterized in that (1) the coating layer is composed of three layers (C-1), (C-2), and (C-3) disposed in this order from the surface side, (2) the layer (C-3) on the base layer side is made of a porous polymeric elastomer, (3) the layer (C-1) on the surface side is made of a polymeric elastomer containing a pressure-sensitive adhesive, and (4) the coating layer comprises one or more polymeric elastomers which have or do not have fine through-holes extending from the surface side to the base layer; and a ball having the skin material bonded to the surface. The skin material for ball-game balls brings about excellent wet gripping and is excellent also in wearing resistance and impact absorption. | ||||||
| 83 | BALLS, BALLOONS AND OTHER INFLATABLE OBJECTS FOR GYMNASTIC OR THERAPEUTIC USE | EP02780765.0 | 2002-06-13 | EP1409088B1 | 2006-09-20 | DONDE' Steno |
| Balls, balloons and other inflatable objects made from a plastic material with an improved resistance to tearing, suitable for use in gymnastic activities, for rehabilitation and physiotherapy comprise as stiffening material an inert mineral charge having a granulometry between 0,02 mu and 500 mu , in an amount between 0,50 % and 20 % by weight. | ||||||
| 84 | Non-woven fabric | EP99307183.6 | 1999-09-10 | EP0987360A3 | 2002-10-23 | Brasier, Alan John |
A ball-covering needlefelt produced by needling a fibre batt in a range of angles including a plurality of angles which are non-perpendicular to the plane of the batt. The range of angles is preferably achieved by the batt being curved during needling, the batt conveniently being curved in its direction of travel through the needling machine. The needleboard of the needling machine is preferably correspondingly curved. The needling process produces a needlefelt having a high degree of fibre entanglement (comparable to woven ball-covering felts) and enables achievement of characteristics necessary for good wear and abrasion resistance without the excessive consolidation in conventional ball-covering needlefelts that leads to loss of flexibility (tending to faulty ball covering) and poor dynamic characteristics (making such balls unsuitable for professional use). The invention is particularly applicable to the manufacture of championship-quality tennis balls. |

| 89 | Triangular pebble design for basketballs | EP85100454 | 1985-01-17 | EP0157083A3 | 1987-06-16 | Martin, Robin Alan |
The surface of a basketball is provided with rows of pebbles or projections, each of which has a flat triangular outer surface and three pointed apexes. The triangles in each row are arranged in alternating directions so that the fingers of a player will engage the pointed apexes of some triangles regardless of the direction in which the fingers extend. |

| 91 | Weighted Tennis Ball | US14884106 | 2015-10-15 | US20160375317A1 | 2016-12-29 | Mark Edward Connelly |
| A tennis ball with weight material injected into its interior cavity for use in exercise and sport as a weight bearing device. The weight material adds weight to the tennis ball. The weight material completely or partially fills the interior cavity of the tennis ball. The weight of the tennis ball can be changed based on the amount and type of weight material inside the tennis ball. | ||||||
| 92 | TAKRAW BALLS | US14889702 | 2014-05-06 | US20160107045A1 | 2016-04-21 | Boonchai Lorhpipat |
| Disclosed is a side strip (10) for weaving into a takraw ball (66); the strip comprising an elongate length of plastics material wherein regions (34) have one or more generally longitudinal slots (38) between outer (30) and inner (40) strip faces; the slots define rattan-like slivers (42) which enable the takraw ball (66) to mimic a traditional rattan takraw ball: a centre strip (46) may be provided with one or more generally longitudinal slots (74a,b,c,d) between outer (52) and inner (56) strip faces; the slots define rattan-like slivers (76a,b). | ||||||
| 93 | SEGMENTED BALL WITH LIGHTED SEGMENTS | US14711496 | 2015-05-13 | US20150246266A1 | 2015-09-03 | Richard E. Zawitz |
| Embodiments of the instant invention include lighted bounceable toys for play and amusement. Such toys or structures can be made in an infinite number of graceful and useful configurations. Exemplary bounceable ball toys include a light assembly having a power source and a plurality of light emitting elements, and a spherical skeletal structure having a plurality of segments. The spherical skeletal structure defines an open interior cavity, and at least some segments of the skeletal structure include a channel opening that faces toward the interior cavity. Light emitting elements transmit light to the channel openings. | ||||||
| 94 | WEIGHTED EXERCISE BALL | US14511029 | 2014-10-09 | US20150099612A1 | 2015-04-09 | Lori A. Beveridge |
| A weighted exercise ball including a weighted, filled core and a plurality of fronds, fringes, or strips radiating from the core. The fringes allow for superior grippability of the ball, which is ideal for training or rehabilitating elderly or injured persons who may not otherwise be able to grip a typical exercise ball or medicine ball. In a preferred embodiment, the weighted core is filled with sand and the fringes extend between two and six inches away from the core. | ||||||
| 95 | Lacrosse Training Ball | US13962271 | 2013-08-08 | US20150045152A1 | 2015-02-12 | Andrew Jeffrey Hayes; Peter Alfred Lawrence |
| A lightweight lacrosse training ball that is suitable for use in lacrosse training drills is lighter, softer, and larger than a regulation lacrosse ball. The lacrosse training ball is comprised of multiple layers: an inner (non-hollow or hollow) layer comprised of a rubber compound; a middle layer comprised of felt or a similar cushioning material; and an outer layer. In one embodiment, the lacrosse training ball is a non-hollow or hollow, lightweight ball with a cushioning layer covered with an outer surface. The light weight of the lacrosse training ball makes it suitable for training where player safety is of concern. The light weight is also advantageous for developing optimal catching ability, forcing players to focus on “giving” with the catch or catching softly. The larger size of the lacrosse training ball increases catching proficiency as there is less room for error in catching a larger ball. | ||||||

| An antimicrobial sports equipment piece used in a sport or game, namely an antimicrobial tennis ball, is described. Also described are methods of using an antimicrobial tennis ball and methods of preventing, inhibiting, or killing microbes contacting the tennis ball during play to prevent or inhibit contamination by a microbe or cross-contamination between persons contacting the tennis ball. | ||||||
| 97 | Water skipping game bag | US12983457 | 2011-01-03 | US08388475B2 | 2013-03-05 | Timothy Leefeldt |
| A water skipping game bag. The game bag can include a liquid-permeable cover having a hydrophobic exterior surface and enclosing an interior chamber, a liquid-permeable pouch disposed within the chamber, a filler material having fluid properties, and a liquid-absorbent core disposed within the pouch. The game bag can absorb water and deform so as to improve skipping performance, increase ease of catching and throwing the bag, and reduce the likelihood of injury from impact by the bag. | ||||||
| 98 | Removable Moisture-Resistant Ball Cover | US13546885 | 2012-07-11 | US20130017912A1 | 2013-01-17 | Cindy DeAngelis-Duffy |
| A removable moisture-resistant ball cover is provided. The ball cover substantially encloses a ball, such as a tennis ball, and includes an opening which can be expanded to attach the ball cover over the ball or remove the ball cover from the ball. The ball cover may be made from a silicone rubber material so as to be resistant to the absorption of liquid and also flexible enough to be easily attached and detached from the ball. The opening may be shaped in a variety of manners, such as a circular, crescent or oval, to permit the opening to be easily expanded to attach or detach the cover from the ball. The ball cover is sufficiently thin to maintain the functionality and usefulness of the dimensions of the ball but sufficiently thick to avoid being easily damaged by an animal which may chew on the ball with the ball cover. | ||||||
