The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
For racket, frame is similar oval in shape, because the bottom of frame is thick and heavy than top usually; Therefore; Shown in Fig. 2 A, a racket 20 of the utility model preferably frame 22 is provided with a hollow-out parts 25a, is positioned at the bottom of frame.Certainly, this hollow-out parts 25b also can be arranged on the top of frame 22 as required, shown in Fig. 2 B.Consider the balance of frame,, need be arranged on the line of symmetry 23 of frame 22 for hollow-out parts 25a or 25b, promptly with frame in pipe 24 corresponding.
What Fig. 3 A-3D showed is the racket 30 of another embodiment of the utility model, on the frame 32 a pair of hollow-out parts 35a and 35b can be set.Certainly, this a pair of hollow-out parts still need be arranged symmetrically in the both sides of frame 32.As preferably, Fig. 3 A shows hollow-out parts 35a of the utility model and the bottom that 35b is arranged on frame, i.e. the horizontal geometric center lines 37 of frame with the lower part.Since from frame 32 begin bottom topmost end to it, thickness reduces successively, therefore, the utility model is arranged on the bottom with hollow-out parts 35a and 35b, can not influence the intensity of frame.Select as another kind, hollow-out parts 35a and 35b also can be arranged on the position of the horizontal geometric center lines 37 of frame, shown in Fig. 3 B, or its above part, shown in Fig. 3 C.In addition, shown in Fig. 3 D, the utility model can also all be arranged on two hollow-out parts on the longitudinal centre line 38, lays respectively at top and bottom.Importantly, the hollow-out parts that is arranged on the diverse location need have the shape that adapts with frame, and is unlikely to influence the intensity of frame.When this hollow-out parts was provided with near connecting portion 18 ', the radian of hollow-out parts was correspondingly bigger, and when what center line 37 of horizontal youngster near frame was provided with, its radian was then milder.
In fact, the hollow-out parts of the utility model can be arranged on a plurality of positions of frame neatly.Shown like Fig. 4 A-4B on the frame of the utility model three hollow-out parts 45a, 45b and 45c can also be set; One of them hollow-out parts 45a is arranged on the longitudinal centre line 38 of frame; Like top (shown in Fig. 4 A) or bottom (shown in Fig. 4 B); Other two hollow-out parts 45b and 45c then are arranged symmetrically in the both sides of frame, like top or bottom.
Obviously, as required, the racket 50 of the utility model can also be provided with two pairs of hollow-out parts, and even five or more.
As shown in Figure 5, if first couple of hollow-out parts 55a on frame 52 and 55b are arranged on its underpart, the second couple of hollow-out parts 56a and 56b should be arranged on the top of frame so.The frame of the utility model preferably adopts carbon fiber to process, and has improved the intensity of racket.
