DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a novel racket, particularly to a racket provided with a shock absorbent and equalizing elastic band.
Conventionally, the racket mainly comprises a frame, a throat and a handle. Within said frame the longitudinal and transverse interweaving strings form the strike surface.
The present invention provides an improved racket with respect to the kind mentioned above, in which at the position inside the frame near to the throat is provided with an elastic band extending transversely over the width of the strike surface, preferably intermitted at the center, which is preformed with a plurality of apertures in a number and at intervals corresponding to the longitudinal strings, so that said longitudinal strings are extended in parallel to each other from top of the frame until passing through said apertures in said band, then extended convergently, to the throat.
BRIEF DESCRIPTION OF THE DRAWINGS
The aforementioned and other objects, features and advantages will be better understood from the following description in detail, with reference to the embodiment illustrated in the accompanying drawings, in which:
FIG. 1 is plane view of one embodiment in tennis racket type of novel racket according to the present invention; and
FIG. 2 is an enlarged transverse cross section of the elastic band according to the present invention.
DETAILED DESCRIPTION OF THE DRAWINGS
Now, referring to FIG. 1, the present novel racket, as usual racket, mainly comprises a frame 1, a throat 2 and a handle 3. Within the area bound by the frame 1, a plurality of longitudinal strings 4 and a plurality of transverse strings 5 are interwoven to form the strike surface. In a kind of conventional racket, the longitudinal strings 4 are extended from top 6 of the frame 1 until the throat 2. Since the width of the frame 1 is far greater than the width of the throat 2, in the conventional racket either the longitudinal strings 4 have no identical length, or the longitudinal strings 4 at both sides are convergently extended to the throat 2 and those closer to the frame sides have greater inclination, except that only two central longitudinal strings 4 are extend substantial parallel to each other until said throat 2.
The present invention is characterized that within the strike surface near to the throat 2 out of the sweet spot is provided with an elastic band 7 extending transversely over the width of the frame 1, namely, from one side to another side of the frame, and preferably intermitted at the center as shown, so that a pair of band sections are substantially presented. The band 7 is made of elastic material, preferably elastomeric resin, in particular polyamides. Meanwhile, as referred to FIG. 2, the band 7 is preformed with a plurality of longitudinal apertures 8 in a number equal to the longitudinal strings 4 which will be passed through. The interval between adjacent apertures 8 corresponds to that between adjacent strings 4. Thereby, all of longitudinal strings 4 are extended in parallel to each other within entire sweet spot of the strike surface until passing through respective apertures 8 of the band 7, then extended convergently from the band 7 to the throat 2 as illustrated.
In cooperation with the inclination when the strings 4 extend from said band 7 to throat 2 convergently, the apertures 8 in the band 7, except those two at center, are formed inclindly towards the center, with inclination incrementally increased towards both sides. The obligue openings 9 at both margin edges are inclined at an angle corresponding to the configuration of the frame 1 at which location the band 7 is mounted, and extend out of the frame 1 to be secured by inserting respective pins 10. The fastening strength of said band 7 will be enhanced by the stress exerted by the longitudinal strings 4 when convergently passing through said band 7. The band 7 is preferably widened at both outer sides since the stress at said outer sides is greater than at inner sides which are thinner.
