20090105019 | BALL CASE, IN PARTICULAR FOR SOCCER BALLS - In a ball case consisting of two-dimensional blanks which are connected with each other at their edges, with the surface of the ball case having a pattern of two different groups of polygons, it is suggested for reducing the number of the two-dimensional blanks and for reducing the overall seam length to combine a first group of polygons consisting of three-armed star-shaped areas with a second group of polygons integrally formed from partial areas of one equilateral triangle and of three equilateral pentagons in such a manner that the pentagonal areas are situated at the points of the corners of the triangle and an imaginary corner and/or the centre of each of the pentagons lies on the perpendicular bisector of the opposite side of the triangle. | 04-23-2009 |
20090186724 | LEATHER-LIKE SHEET AND METHOD OF PRODUCING LEATHER-LIKE SHEET - An object of the invention is to provide a leather-like sheet having excellent water absorbability (sweat absorbability, defined the same hereinafter), providing a natural leather-like touch, and suitably used as a ball covering or a non-slip covering, without lowering surface wear resistance. An aspect of the invention is directed to a leather-like sheet including a base material having an entangled fiber sheet; and a porous elastic resin layer laminated on a surface of the base material. The porous elastic resin layer has a concave-convex surface. The concave-convex surface of the porous elastic resin layer includes a projection having a top surface and a side surface, and a recess having a bottom surface contiguous to the side surface. The top surface of the projection has openings with a diameter from 10 to 500 nm at a density of 1,000 openings/mm | 07-23-2009 |
20100130317 | NEW KIND OF FOOTBALL WITH IMPROVED ROUNDNESS - Ball, composed of an inflatable inner ball from a thin rubbery material and of an outer skin from a leathery material, usually a fibre reinforced flexible plastic, composed in balls of the first type of twelve more or less pentagonal parts and twenty more or less hexagonal parts and in balls of the second type of six more or less square parts and eight more or less hexagonal parts, where most of the edges do not have a kinked form but follow a circular course, so that they follow accurately the curvature of the sphere. An even better approximation of the sphere form is obtained, if the dimensions of the parts are changed in such a way that all corners of these parts are lifted towards the sphere surf ace and do not lie slightly under this surface as in the aforementioned patent. | 05-27-2010 |
20100160096 | PANEL OF A BALL FOR A BALL GAME, A BALL, AND METHODS OF MAKING THE SAME - The present invention provides a panel of the ball for ball game, said panel has the folding portion and the opposite folding portion on its periphery, which are opposite to each other and made of the same continuous material. The folding portion and the opposite folding portion of said leather panels have the good engaging property and difficult to separate with each other during usage because they are made of the same material. The panel has simple manufacturing process and low production cost, making the ball for ball game comprising above panels have good using properties, simple manufacturing process and low production cost. | 06-24-2010 |
20100261563 | NOVEL TENNIS BALL - Tennis ball which comprises an elastomeric polyurethane foam having a ball shape and a density of 250-800 kg/m | 10-14-2010 |
20110306448 | WATER BOUNCING BALL - A water bouncing ball includes a gel core made of plastic material and an elastic porous plastic material adjacent the gel core and covering and centering the gel core in the middle of the ball. The ratio between the diameter of the gel core and the thickness of the elastic porous plastic material is in the range between 0.66 and 2.8. In this way a soft floating ball having good bouncing ability is provided. | 12-15-2011 |
20120231908 | Sports Ball - Surface panels of a sports ball are arranged to facilitate bending of their outer peripheral edge portions into an arc, without reducing strength of an elastic member, to define a groove at a seam between adjacent panels. Panels are adhered through the elastic members to a body defining a ball core with high adhesion strength. The panels have sheet material backed by an elastic member, each panel having an arched portion formed by bending inwardly an outer peripheral edge portion of each panel with a radius of curvature more than the thickness of the panel, after formation of many apertures in an inner peripheral edge portion of the elastic member. Lower edges of the arched portions of adjacent panels abut each other. A groove is defined at seams between adjacent panels, and the panels are adhered to a ball core body by adhering the elastic members to the body. | 09-13-2012 |
20120244971 | BALL COVER STRUCTURE OF BASEBALL OR SOFTBALL - In a structure of a ball cover of a baseball or softball, the ball cover is manufactured from PU material, and the ball cover is one unit from the ball core to the outside of the ball, and a raised sewn section is formed thereon, and the raised sewn section is situated along the mold line on the surface of the ball cover. The PU material is used to replace leather in the manufacture of the ball cover, thereby reducing material costs. Utilizing a mold to directly form the ball cover, and a mechanized production process effectively increases the production rate and reduces worker costs; moreover mechanized production ensures uniformity of the ball, thereby producing balls with precise standards of pressure resistance and bounce values and so on; a ball cover directly formed as one unit and with good overall surface qualities makes it hard for the ball core to be soaked and the sewn section to break, therefore it's extremely waterproof and the outside environment has little effect on the ball, moreover PU material overall displays better durability and resistance qualities than leather, thereby effectively increasing the lifespan of the ball. | 09-27-2012 |
20120277044 | Sports Ball Casing And Methods Of Manufacturing The Casing - A spherical sport ball may include a casing that includes first and second substantially hemispherical panel components. Each substantially hemispherical panel component may be a unitary structure having a central panel and a plurality of polygonal peripheral panels adjacent to the central panel. In addition, the first substantially hemispherical panel component may be joined with the second substantially hemispherical panel component at a non-linear, circumferential seam between peripheral panels of the first hemispherical panel component and peripheral panels of the second hemispherical panel component. | 11-01-2012 |
20130017912 | Removable Moisture-Resistant Ball Cover - 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. | 01-17-2013 |
20140024484 | Soccer Ball With Motion Graphic - Balls for team and individual sports include a motion graphic that provides enhanced perception of ball rotation. The motion graphic is typically defined with a visual characteristic that contrast with a ball casing. The motion graphic includes first and second termination portions that are coupled by a connection region. The first and second termination portions are symmetrically situated with respect to a longitudinal axis and are asymmetric with respect to axes perpendicular to the longitudinal axis. The motion graphic and the ball casing can be provided with substantially opposite colors selected to exhibit similar or substantially the same reflectivities. | 01-23-2014 |
20160375316 | Low Bounce Hockey Ball - The low bounce hockey ball is comprised of an outer shell and a dampening material enclosed within the outer shell. The dampening material absorbs the rebounding energy of the low bounce hockey ball during a bounce. The materials used in construction of the low bounce hockey ball does not bounce on its own and cancels the energy of the outer ball shell during its rebound. | 12-29-2016 |
