DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Please first refer to FIGS. 1 and 2 which show one preferred embodiment of this invention. The racket frame 10 of this invention is substantially oval-shaped comprising a handle portion 13 and a hitting portion 120 integrally formed together. The hitting portion 120 includes a hollow annular frame body 10A and a tension hitting surface 20. The tension hitting surface 20 can be a well resilient artificial fibrous fabric such as knitting fabric, plastic fabric or drumhead material, etc. It can be seen from FIG. 2 that the peripheral size of the tension hitting surface 20 is larger than the center-to-center size of the frame 10 but smaller than the actual size of the frame 10. Multiple fixing holes 21 are formed along the periphery of the hitting surface 20. The center connecting lines of these holes 21 fall within the center line of the frame 10. These holes 21 are distributed along the periphery of the hitting surface 20 at equal intervals. Preferably, at least eight fixing holes 21 are disposed so as to sufficiently evenly share the flatness of the hitting surface 20. As shown in FIG. 2, the frame 10 is composed of a female member 11 and a male member 12 secured thereto, wherein the female member 11 has a semicircular cross-section and the outer side of the female member 11 is formed with a shoulder 111 and a projection 112 from outside to inside. The inner central portion of the female member 11 is formed with multiple equally spaced insert holes 113. Correspondingly, the male member 12 also has a semicircular cross-section and the outer side of the male member 12 is formed with a projection 121 and a shoulder 122 from outside to inside. The inner central portion of the male member 12 is formed with multiple equally spaced insert pins 123 corresponding to the insert holes 113 of the female member 11. When said insert pins 123 of said male frame member 12 is correspondingly inserted into said fixing holes 21 of said hitting surface 20 and the insert holes 113 of said female member 11, the peripheral portion of said hitting surface 20 will be firmly clamped by both of the inner peripheral annular portions of said female male frame members 11 and 12. Thus, the hitting surface 20 with a desired tension and a resonating sound box inside said hollow annular frame body 10 and said handle portion 13 is thus formed.

In order to increase the tension applied on the hitting surface 20, according to the present invention, another embodiment of the frame body 10 is made in such a manner that between the insert holes 113 and the inner periphery of the female member 11, along the inner periphery thereof, an inward extending annular protrusion 114 is formed on the female member 11 and between the insert pins 123 and the inner periphery of the male member 12, along the inner periphery thereof, an inward extending annular groove 124 is also formed on the male member 12, whereby when the male member 12 is secured to the female member 11, the insert pins 123 of the male member 12 are inserted into the insert holes 113 of the female member 11 and the annular protrusion 114 of the female member 11 is fitted into the annular groove 124 of the male member 12. Therefore, when mounting the hitting surface 20, the fixing holes 21 thereof are first fitted to the insert pins 123 and the hitting surface 20 is totally laid over the male member 12 of the frame 10. As shown in FIG. 2, the size of the hitting surface 20 is smaller than the size of the outer periphery of the frame 10. Then the female member 11 is laid over the male member 12 and the annular protrusion 114 thereof extrudes the outer peripheral portion of the hitting surface 20 into the annular groove 124 of the male member 12. Because the groove 124 has a considerable depth, when the female member 11 is fitted with the male member 12, a considerable length of hitting surface 20 is secured into the groove 124 so that the hitting surface 20 is thereby highly tensioned and the male and female members 12, 11 of the frame 10 are firmly associated together. Such assembly has a simple structure and can be assembled quickly and conveniently. In addition, when assembled, the hitting surface 20 is effectively and highly tensioned.

It should be noted that the bonding of the male frame member and the female frame member may just as readily be accomplished by providing the male frame member with at least one an annular protrusion and the female frame member with at least one an annular groove.

Referring to FIG. 3, for achieving a more reliable securing effect of the frame 10, besides the first annular protrusion 114 of the female member 11, a second annular protrusion 114A is additionally formed on the female member 11, and a second additional annular groove 124A is also formed on the male member 12. As a result, a further high tension hitting surface 20 secured in the frame 10 can hardly become loosened or detached.

Furthermore, as shown in FIG. 1, a handle 13 is disposed right under the racket for a single hand to grip. Alternatively, as shown in FIG. 5, two handles 13A, 13B can be disposed on two sides of the racket for both hands to grip. Such both hand use is helpful to the exercise of the shoulders, neck and arms of the player.

It should be noted that since the high tension hitting face 20 of this invention is made of plastic fabric or drumhead material and, since the fabric or drumhead material is highly tensioned and firmly clamped by the frame 10, and the frame 10 is a hollow annular body forming a close sound box, when a ball member (which can be any object having suitable weights and shapes) is hit by the racket, a sound like the drum beat is emitted. This will make the game of hit much more interesting to the players.

It should be also noted that in case the tolerance between the insert holes of the female member and the insert pins of the male member is increased or changed due to the alteration of the material properties and processing conditions during the molding procedure, the male and female members can be nevertheless assembled and then be thermally sealed and melted into an integrated member by a high frequency thermal wave welding machine without needing to use any screw for securing.
