Definitions

  • the present invention relates to a sportsball, and more particular to a sportsball with sculptural ball surface that creates maximum grip and speed of the sportsball and enhances the aesthetic appearance of the sportsball.
  • a conventional sportsball such as a conventional soccer ball, usually comprises a ball bladder, an inner lining, and a ball casing.
  • the ball casing comprises a plurality of cover panels stitched edge to edge together to cover or attached on the ball bladder.
  • each of the cover panels is stitched to adjacent cover panels for forming a substantially round sportsball.
  • the cover panels can be made of leather or rubber.
  • the leather made cover panels are durable and flexible material made by the tanning of animal rawhide and skin.
  • Each of the leather made cover panels has a plurality of different sized grains naturally formed on the panel surface and having breathability. Accordingly, the sportsball with the leather made cover panels, such as basketball and volleyball, is mainly for indoor activity. It is known that water and moisture is not good for leather. If the leather made cover panels get wet and then dries, the cover panels can crack and dry out. In other words, most indoor sportsballs are not made by the leather made cover panels.
  • a logo or design can be printed on the cover panels. However, the logo or design cannot be perfectly printed on the surface of the cover panels because of the naturally formed gains.
  • the rubber or synthetic leather made cover panels can solve the above mentioned problems of the leather made cover panels. Accordingly, the rubber made cover panels are durable and waterproof such that the outdoor sportsball, such as soccer ball, is made by the rubber or synthetic leather made cover panels. Furthermore, the rubber or synthetic leather made cover panel has a smooth surface, such that the logo or design can be easily printed on such cover panels.
  • one drawback of the rubber or synthetic leather made cover panels is that there is no grain formed on the smooth panel surface. Therefore, the sportsball with the rubber made cover panels will substantially reduce the surface friction, such that the sportsball with the rubber made cover panels is too slippery and is hard to control.
  • the ball manufacturer will intentionally form the grains on the rubber made cover panels by pressing a plurality of fine grooves to be indented on the panel surface to form a "texture" thereon.
  • the indented grooves will substantially reduce the aesthetic appearance or even destroy the logo or design printed on the sportsball.
  • the manufacturing process of the cover panel will be complicated to involve the formation of the texture.
  • the texture must be formed on the panel surface of the cover panel before the cover panels are attached on the ball bladder. Therefore, the grains at the edge of the cover panel will be partially cut.
  • the texture at the edges of the cover panels will be damaged. In other words, when the edges of the cover panels are pressed to form the channels of the sportsball, the grains will be disappeared at the channels of the sportsball.
  • U.S. Pat. No. 8,388,476 to Tsung Ming OU who is the applicant of the present invention, disclosed a sportsball which comprises a ball pocket constructed to have a true roundness shape and to receive the inflatable bladder therein. Therefore, when the inflatable bladder is inflated, the ball pocket retains a true roundness shape of the inflatable bladder.
  • U.S. Pat. No. 6,656,067 to Tsung Ming OU who also is the applicant of the present invention, disclosed a sportsball which comprises an exterior web layer integrally adhered on an outer surface of the inflatable bladder. Therefore, when the inflatable bladder is inflated, the exterior web layer retains a true roundness shape of the inflatable bladder.
  • the invention is advantageous in that it provides a sportsball with a sculptural ball surface that creates maximum grip and speed of the sportsball and enhances the aesthetic appearance of the sportsball.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein the sculptural design and pattern can be selectively formed on the sportsball surface not only to increase the frictional surface but also to enhance the aesthetic appearance of the sportsball.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein a plurality of sculptural bumps (or pimples) are raised above an outer panel surface of the cover panel to form the sculptural ball surface to enhance the grip and speed of the sportsball.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein no depression force is required for applying on the outer panel surface of the cover panel in order to indent the outer panel surface of the cover panel. In other words, there is no damage on the outer panel surface of the cover panel in order to form the sculptural ball surface.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein the manufacturing method is simple, cost-effective, and efficient.
  • the present invention provides an optimal method of producing a large quantity of sportsball in a relatively short period of time.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein the sportsball can be manufactured into a wide variety of ball types, so as to facilitate widespread applications of the present invention.
  • the sportsball can be manufactured as a soccer ball, an America football, or even a volley ball.
  • Another advantage of the invention is to provide a sportsball with a sculptural ball surface, wherein no expensive or complicated structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for providing a secure and reliable configuration for detachably mounting additional accessories at the firearm with compact and ergonomic design.
  • the ball carcass in the step (d), can be made by stitching the cover panels edge to edge together to form a ball shape and the ball body is enclosed inside the ball carcass. In one embodiment, in the step (d), the cover panels are overlapped on the ball body to form the ball carcass in a stitch-less manner, wherein the cover panels are interlocked and bonded with each other edge-to-edge to enclose the ball body inside the ball carcass.
