Definitions

  • the present invention relates to a racket with a center of gravity thereof approximate to a center of a rubber sheet of the racket, and especially to a racket whose center of gravity moves approximately to the center of rubber sheet and is located in a high ball-strike area, thereby enhancing attack and defense abilities of the racket, and reducing shock.
  • FIGs. 1-4 illustrate a conventional racket.
  • a head 12, 22 of the racket is substantially square-shaped (racket 1), or is substantially circular-shaped (racket 2).
  • the rackets 1, 2 comprise blades 11, 22 and rubber sheets 14, 24.
  • the blades 11, 21 comprise heads 12, 22, necks 102, 202 and handles 13, 23.
  • the rubber sheets 14, 24 are attached on the heads 12, 22.
  • a connecting line connecting two outermost points of the heads 12, 22 (line connecting two respective outermost points of two sides of the head) is positioned substantially in a front end of a rear half portion of the heads 12, 22.
  • the centers of gravity 101, 201 are positioned in a place substantially adjacent to rear ends of the rubber sheets.
  • An object of the present invention is to provide a racket with a center of gravity approximate to a center of a rubber sheet, in which the center of gravity approaches the center of the rubber availably.
  • the center of gravity of the racket is moved into a high ball-strike area, thereby hitting more high-energy balls to improve attack, decreasing a chance of losing a ball to a firm defense, and reducing shock to get a better striking feel.
  • a racket with a center of gravity approximate to a center of a rubber sheet has a blade comprising a head.
  • the head becomes gradually narrower from front to back, and a line connecting two outermost points of the head is positioned in a front half portion of the head.
  • a racket with a center of gravity approximate to a center of a rubber sheet of the present invention is provided.
  • Figs. 5-7 show a first racket 3 of the present invention that is an improvement upon the conventional square racket
  • Figs. 8-9 show a second racket 4 of the present invention that is an improvement upon the conventional circular racket.
  • each of rackets 3, 4 of the present invention comprises a blade 31, 41, and a rubber sheet 34, 44.
  • the blades 31, 41 comprise a head 32, 42, a neck 302, 402, and a handle 33, 43, respectively.
  • the rubber sheets 34, 44 are attached to the heads 32, 42.
  • the necks 302, 402 are disposed between the heads 32, 42 and the handles 33, 43.
  • the heads 32, 42 are substantially trapezoid-shaped.
  • the front ends of the heads 32, 42 define an arched wide side, respectively (shown in Fig. 8). A line connecting outermost points of the arched wide sides or other shape of wide sides is disposed in a half portion of the heads 32, 42.
  • the two arched wide sides gradually narrow from the two outermost points to the necks 302, 402 to define two sides of the heads 32, 42.
  • a narrow side is formed in the rear ends of the heads 32, 42.
  • the heads 32, 42 are trapezoid-shaped when seen from the wide sides to the narrow sides.
  • the square racket is improved to a trapezoid-shaped racket or the circular racket is improved to a trapezoid-shaped racket, making the centers of gravity 301, 401 of the rackets 3, 4 close to the centers of rubber sheet 341, 441.
  • Fig. 7 illustrates a handle 33 of the first racket 3
  • Figs. 8-9 illustrates a handle 43 of the second racket 4.
  • the handle 43 is formed by removing part of a rear end of the handle 33 and a concave portion 331 is defined.
  • a hole 431 is bored along an axial direction in the rear end of the handle 43, and the hole 431 maybe a single hole or a plurality of holes with different sizes. This can lighten the handles 33, 43 and make the centers of gravity 301, 401 even closer to the centers of rubber sheet 341,441.
  • the centers of gravity 301, 401 of the rackets 3, 4 can be closer to the centers of rubber sheet 341, 441 compared to the centers of gravity 101, 201 of the conventional rackets by making the heads 32, 42 gradually narrower from front to back and lightening the handles 33, 43.
  • the heads 32, 42 or the rubber sheets 34, 44
  • the centers of gravity 301, 401 of the rackets 3, 4 are positioned in the high ball-strike area of the middle, but the center of gravity 101 (201) is positioned beyond the area.
  • the racket with a center of gravity approximate to a center of a rubber sheet of the present invention has the following advantages: First, the centers of gravity 301, 401 are closer to the centers of rubber sheet 341, 441. Because the player will strike balls with the centers of rubber sheet 341, 441, areas adjacent of the centers of rubber sheet 341, 441 are in the high ball-strike area. In other words, the centers of gravity 301, 401 can be positioned in the high ball-strike area. Second, because the centers of gravity 301, 401 all move forwardly, the moment is increased. Third, because the centers of gravity 301, 401 are in the high ball-strike area (even when the moment is increased), high energy balls can be hit in areas adjacent the centers of gravity 301, 401.
  • Balls are thus hit more aggressively, and making various games more fun and popular.
  • Fourth because the areas of the half front portion of the heads 32, 42 are increased, it is difficult to lose balls far from the player, which enhances the defense.
  • Fifth because the strike points are close to the centers of gravity 301, 401, shock can be reduced.
  • Sixth because the front ends of the rackets 3, 4 are wide sides, wind fanned from the rackets 3, 4 is bigger than that of the conventional square racket and the circular racket, making them more useful for a player to disseminate heat.
  • Seventh because the rackets 3, 4 (blades 31, 41) are substantially triangular in shape, the rackets 3, 4 can be incised with little waste to satisfy environmental protection regulations.
  • the racket with a center of gravity approximate to a center of a rubber sheet of the present invention can indeed solve the problems of the prior art.
