  • FIG. 9 is a cross sectional view taken along lines [0022] 9-9 of FIG. 8.
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to the drawings, and initially to FIGS. [0023] 1-3, a golf club in accordance with the present invention comprises a club body 3, a hand grip 8 formed or provided or attached to one end, such as the upper end of the club body 3, and a club head 9 formed or provided or attached to the other end, such as the lower end of the club body 3. The club body 3 normally includes a width or a cross section area gradually reduced from the upper end that close to the hand grip 9, toward the lower end that close to the club head 9.
  • The [0024] club body 3 includes a longitudinal structure having a pair of inclined surfaces 31, 32 formed in the front portion 30 thereof that faces toward the wind (FIGS. 3, 6, 9) while swinging the club body 3, and having a cusp 33, such as a rounded cusp 33 formed or defined in the front portion of the inclined surfaces 31, 32, or formed in the leading edge of the club body 3.
  • As best shown in FIG. 3, the [0025] club body 3 includes a flat surface 300 formed or defined in the rear portion thereof, and includes a number of air passages 41, 42 formed therein, such as formed between the inclined surfaces 31, 32 and the flat rear surface 300 respectively, for allowing air to flow through the air passages 41, 42 of the club body 3.
  • The [0026] club body 3 may further include one or more depressions 34 formed therein, such as formed in one or more portions thereof, particularly formed in one or more portions of the inclined surfaces 31, 32 thereof, for forming or defining one or more reduced segments 40 that have a width or cross section area less than the other portion of the club body 3, and for forming or defining one or more shoulders 43 between the segments 40 and the other portion of the club body 3.
  • The reduced [0027] segments 40 each also includes a pair of inclined surfaces 35, 36 formed in the front portion thereof, and preferably parallel to the inclined surfaces 31, 32 of the club body 3. The formation or the provision of the shoulders 43 in the club body 3 may be used for reducing the vibration or oscillation from the club head 9 toward the hand grip 8.
  • In operation, as shown in FIG. 3, while striking golf balls with the [0028] club body 3 or while swinging the club body 3, some of the air may flow toward the rear portion of the club body 3 via the inclined surfaces 31, 32, or 35, 36 of the club body 3. In addition, the air may also flow through the air passages 41, 42 of the club body 3, in order to reduce eddy current in the rear portion of the club body 3. The golf club may thus be precisely directed toward the predetermined direction, and the golf balls may thus be precisely stricken toward the predetermined direction and position.
  • Referring next to FIGS. [0029] 4-6, illustrated is another embodiment of the golf club. In the golf club, without the air passages 41, 42 formed in the club body 3, the club body 3 further includes a pair of inclined surfaces 37, 38 formed in the rear portion thereof that faces away from the wind (FIGS. 6, 9) while swinging the club body 3, and a cusp 39 formed or defined in the rear portion of the inclined surfaces 37, 38, or formed in the rear portion of the club body 3. The air may also be fluently or smoothly flown through the club body 3 without generating eddy currents in the rear portion thereof.
  • Referring next to FIGS. [0030] 7-9, illustrated is a further embodiment of the golf club. The club body 3 may further include two curved side surfaces 45, 46 formed therein, or formed between the inclined surfaces 31, 32; and 37, 38 respectively. The air may also be fluently or smoothly flown through the club body 3 without generating eddy currents in the rear portion thereof.
  • Accordingly, the golf club in accordance with the present invention includes a stabilized air flow or aerodynamic structure for allowing the golf club to be precisely directed toward the predetermined direction, and for allowing the golf balls to be precisely stricken toward the predetermined direction and position. [0031]
  • Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed. [0032]
