| 20120035008 | BASEBALL - There is provided a baseball including an inner core, and an outer core covering an outer circumferential surface of the inner core, the inner core being formed to have a dimension of 20% or more and 80% or less of an outer diameter of the inner core and the outer core of the baseball, and having a dynamic viscoelasticity loss coefficient (tanĪ“) of 0.3 or less, the outer core being formed to have a thickness of 10% or more and 40% or less of the outer diameter of the inner core and the outer core of the baseball, and having an elastic modulus of 1.5 MPa or less. As a result, there can be obtained a baseball that achieves a high level of safety when the baseball hits against a human body and achieves a hit distance equal to and longer than that of a ball for hardball. | 02-09-2012 |
| 20120058844 | Composition of baseball's core - A baseball includes a core comprised of coconut fiber, rubber, and solvent; and a cover sewn on the core by stitches. The coconut fiber having a predetermined percentage by weight is crushed, the rubber having a predetermined percentage by weight is gelled, the coconut fiber and the rubber are mixed with the solvent having a predetermined percentage by weight, and the mix is subjected to molding, heating, and cooling to produce the core. | 03-08-2012 |
| 20120316015 | LAMINAR BALL - A laminar ball includes a spherical rubber core member, a reinforcing thread layer formed of a mixture of threads and latex and surrounding the spherical rubber core member to have the latex be bonded with the spherical rubber core member, an outer rubber layer surrounding the reinforcing thread layer and bonded with the latex and having intersected reinforcing ribs, a rubber surface layer bonded to the outer rubber layer, and a plurality of grooves defined in the rubber surface layer corresponding to the reinforcing ribs. | 12-13-2012 |
| 20150126312 | BALLS FOR USE IN OFF-ICE HOCKEY TRAINING - This disclosure includes street hockey balls for use in games and/or training on off-ice surfaces (e.g., paved asphalt, paved concrete, and/or the like). The present hockey balls can be configured to emulate the bounce or rebound characteristics of a hockey puck on ice. For example, versions of the present hockey balls can include a core of a low rebound material and a covering or coating of a hard, tough material. Versions can have a weight greater than that of a hockey puck to facilitate strength training by which a player's wrist, shoulder, back and hand strength and endurance can be improved, and/or can have a height selected to simulate the feel of a hockey puck while still being low enough to facilitate speed or stickhandling training by which a player's stick speed or stickhandling skills can be improved. | 05-07-2015 |
| 20150297954 | MOLDED GAME BALL - A molded game ball comprises an outer cover or surface having a mold line that mimics the seam of a conventional baseball or softball. The outer cover or surface may additionally include a stitch pattern that mimics the stitching of a conventional baseball or softball. | 10-22-2015 |
| 20150367217 | RAISED SEEM BASEBALL TRAINING DEVICE - A first baseball comprises a skin portion and a first seam portion higher than a second seam portion. A second baseball comprises a skin, a first seam portion having a first stitches pattern, and a second seam portion having a second stitches pattern different from the first stitches pattern. A baseball training kit comprises a skin portion and a first seam portion having a first stitches feature and a second seam portion having a second stitches feature different from the first stitches feature. | 12-24-2015 |
| 20160144243 | SPORTS BALL AND METHOD OF MANUFACTURE - A sports ball comprising an inner core with a plurality of nubs on its exterior surface, and an outer shell comprising two hemispheres that surround the inner core such that the plurality of nubs contact the inner surfaces of the outer shell's inner cavity. The outer core can comprise a cross-linked closed-cell foam such that the sports ball can be more durable and softer than conventional balls normally used for the same sport. | 05-26-2016 |
| 473601000 | And having intermediate layer between core and cover or having core or cover composed of plural layers | 4 |
| 20110065536 | 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. | 03-17-2011 |
| 20110160011 | SOFTBALL - An improved softball that resists the softening effects on the core that ultraviolet light impinging upon the ball and warm ambient air cause. The softball has a coating on the core that blocks most or all of the ultraviolet light impinging upon the ball from penetrating to the core. Also, the ball's core can have a modified chemistry that causes the core to resist softening even if the core gets warmer from ambient air (i.e., without any light impinging upon the ball). | 06-30-2011 |
| 20120244970 | BASEBALL - A baseball includes an inner core, and an outer layer covering the outer circumferential surface of the inner core. The inner core has a surface hardness of not less than 60 and not more than 80 in Asker C hardness, and has an elastic modulus of not less than 0.6 MPa and not more than 1.0 MPa. In this way, a baseball can be obtained which can achieve a trajectory comparable to that of a ball for hardball after hitting and which can achieve an impact force comparable to a ball for rubber-ball baseball. | 09-27-2012 |
| 20130012344 | BASEBALL WITH IMPROVED CORE AND ENHANCED DURABILITY - A baseball capable of being tested under ASTM F1887-09 wherein the baseball is projected at a strike plate at a speed of approximately 60 mph to measure the COR of the baseball. The baseball includes a core formed of a diene-based rubber composition, at least one layer of yarn surrounding the core, and a cover assembly surrounding the one layer of yarn. The core has a diameter of less than 2.0 inches and a weight less than 1.5 ounces. The baseball has a circumference of less than 9.5 inches and a weight of less than 5.5 ounces. The baseball has an initial COR value when tested in accordance with ASTM F1887-09 and a second COR value measured after the baseball has undergone at least 60 impacts of approximately 60 mph against the strike plate. The second COR value is greater than 95 percent of the initial COR value. | 01-10-2013 |
