20110136604 | Ball body - This invention relates to a ball body which essentially comprises a transmitting hollow inner bladder. A recessed socket for accommodation of a vibration-powered luminous body is provided on the transmitting hollow inner bladder. A superficial layer is further wrapped on outside surface of the transmitting hollow inner bladder, which has transmitting areas provided thereon. When the ball body is played to produce vibration, the vibration-powered luminous body is lightened and light is scattered out through the transmitting hollow inner bladder and the transmitting areas on the superficial layer so as to increase more fun in playing the ball and diversified functions of toy. | 06-09-2011 |
20130085023 | INNER TUBE HAVING A REINFORCED CORE MEMBER STRUCTURE FOR BALL SPORTS - An inner tube having paper strips, which are made of rayon fibers of natural pulp having a rayon structure and capable of being decomposed by biological agents when the ball is worn out, arranged into abutted parallel pairs and respectively bonded to the front side, back, top, bottom, left and right sides of the spherical rubber body thereof with latex adhesive evenly in multiple layers to reinforce the structural strength, assuring even distribution of wall thickness and enhancing ball durability. | 04-04-2013 |
20130165281 | INFLATABLE LATEX NEOPRENE BLADDERS - The present invention relates to inflatable neoprene bladders and method of manufacturing inflatable neoprene bladders. The invention also relates to inflatable articles having an inflatable neoprene bladder wherein the article has an idealized shape and superior resiliency and air retention. Finally, the invention relates to sportsballs and gameballs having an inflatable neoprene bladder. | 06-27-2013 |
20150045161 | Cellulose Acetate Table Tennis Balls and Processes for Making - The present invention is directed to cellulose acetate table tennis balls and to processes for forming the cellulose acetate table tennis balls. Cellulose acetate may be provided as a flake or powder and then may be melt extruded to a sheet or pellet. The sheet may be soaked and a plurality of coupons may then be cut from the sheet. The coupons may be melt extruded to form hemispheres and then two hemispheres may be adhered to each other to form a sphere. The pellets may be injection molded to form hemispheres and then two hemispheres may be adhered to each other to form a sphere. The cellulose acetate table tennis balls are free of celluloid but meet the International Table Tennis Federation standards for table tennis balls. | 02-12-2015 |
20160074713 | TABLE TENNIS BALL AND TABLE TENNIS BALL-USE THERMOPLASTIC RESIN COMPOSITION - A table tennis ball faithfully reproduces the playing characteristics of celluloid table tennis balls without using celluloid, and a thermoplastic resin composition for table tennis balls provides a table tennis ball having an excellent balance of elastic modulus, impact resistance, and density. The table tennis ball is composed of a celluloid-free thermoplastic resin or thermoplastic resin composition having a flexural modulus according to ISO 178 of 1650 MPa or more, a Charpy impact strength according to ISO 179 of 20 kJ/m | 03-17-2016 |
20160096080 | Football - A football that is substantially in the shape of a corn on the cob or a cooked ear of maize configured to be thrown similarly to a conventional football. The football includes a body portion having a blunt end that tapers towards a tapered end. An outer surface of the body portion includes a plurality of kernels aligned in a plurality of parallel rows that is configured to encircle the body portion. The blunt end includes a plurality of extensions that extend outwardly therefrom. Depending upon the embodiment, the extensions may include feathers having a stem and one or more vanes, or the extensions may include husk-like members. The extensions help to stabilize the football during flight and provide a fluttering appearance while the football is thrown. | 04-07-2016 |
473610000 | With sealable opening, valve, or inflation tube for insertion of fluid (e.g., beach ball, etc.) | 3 |
20080268990 | Toy Ball - To provide a toy ball which includes an air plug which facilitates the injection and discharge of air and which does not have to be plugged immediately after the completion of air injection, a toy ball is made up of a ball main body which has an air hole in a predetermined position and which is formed into a spherical body by injecting air into an interior thereof and a hollow rod-like air plug which is freely detachably mounted in the air hole in the ball main body and which allows air to be injected therethrough while kept mounted in the air hole, and the air plug is made up of a pipe-like air injecting pipe having an enlarged portion at an outer end portion thereof, an air flow-in member which is mounted at an inner end portion of the air injecting pipe and which has a space in an interior thereof, and a spherical valve which is inserted in the space in the air flow-in member in such a manner as to be sorbable movable state to a distal end of the air injecting pipe so as to be secured thereto. | 10-30-2008 |
20100167851 | Hooded Valve and Valve Assembly for an Inflatable Object - A hooded valve and valve assembly for use in inflatable objects, especially inflatable balls with an internal bladder that are inflated through insertion of an air needle, are disclosed. The valve includes an exterior chamber for easy insertion of the needle, a closed central portion for retention of air once the needle is removed, and a flexible interior chamber for enabling air to flow from the needle and to prevent the needle from puncturing the ball or the bladder. | 07-01-2010 |
20130252771 | BALL INFLATION VALVE - A ball inflation valve includes a valve body extended into an inflatable inner bladder of a ball and having an axial bore and an annular flange portion; a valve core partially held in the axial bore of the valve body and having an air hole; a canvas superimposing layer flatly superimposed on the annular flange portion of the valve body to locate around the valve core; and a protective top including a sleeve portion enclosing a length of the valve core exposed from the valve body and a locating flange portion radially outward extended from the sleeve portion to locate between a surface cover of the ball and the valve body and the valve core, so that any sulfide from the valve body and the valve core will attach to an inner side of the protective top without forming a yellowing smudge on the ball surface cover. | 09-26-2013 |
