Abstract

An improved badminton racket is provided with a ring frame, a shaft handle and a throat part connecting the ring frame and the shaft handle, wherein the ring frame is formed by bending a metal pipe and is provided with a long shaft and a short shaft which are perpendicular to each other, the shaft handle is made of fiber reinforced plastic, one end of the shaft handle is converged with one end of the long shaft of the ring frame, and the throat part is wound and coated at the junction of the shaft handle and the ring frame by a multi-layer fiber reinforced plastic coating.

Description

Badminton racket

The utility model is relevant with sporting racket, particularly about a kind of modified form racket.

Traditional racket is generally with a kind of usefulness that is referred to as the three links T connector for ring frame two opposite ends and footstalk upper end intercalation, so that the two is linked together, this kind is configured in actual use and goes up unsatisfactory, because the intercalation end of this footstalk strike at the ball hard or use a period of time after tend to break away from the through hole of this T connector, and making racket to use, the junction of this T connector and ring frame and footstalk can form the rank portion of projection and causes and apply the difficulty of installing in addition.

Therefore, main purpose of the present utility model is promptly providing a kind of modified form racket, and it can make footstalk and ring frame be bonded together closely.

Another purpose of the present utility model is also providing a kind of ring frame and footstalk joint of making very level and smooth, does not have the modified form racket of the rank portion generation of projection.

For reaching aforementioned purpose, the utility model modified form racket includes a ring frame, one footstalk, an and throat that connects this ring frame and this footstalk, it is characterized in that this ring frame is bent to form by tubular metal and has orthogonal minor axis and major axis, the elongated tubular of this footstalk for being made by the fiber reinforcement type plastic cement, one of one end and this ring frame major axis are held and are joined, this throat includes a multilayer shape fibre reinforced plastic coating, is coated on the meet of this ring frame and this footstalk; Whereby, this throat can be after this encircles frame and the equal moulding of this footstalk, be coated on earlier both meets with unhardened fiber reinforcement type plastic layer still, and then give pressurized, heated and hardened forming is a multilayer shape coating, this kind mode can make ring frame and footstalk combine very closely, and can not produce the rank portion of projection.

Now with embodiment and conjunction with figs., the utility model is described in further detail, in the accompanying drawing:

Fig. 1 is the stereogram of the utility model one preferred embodiment;

The cutaway view of Fig. 2 for being got along the 2-2 direction in the utility model Fig. 1 preferred embodiment;

Fig. 3 is the phantom of another preferred embodiment of the utility model;

Fig. 4 is the utility model phantom of a preferred embodiment again.

At first, see also Fig. 1 and Fig. 2, the racket 10 of the utility model one preferred embodiment has an aluminium-alloy pipe and bends the ring frame 12 that forms, and constitutes striking surface, a footstalk 16 in order to wear netting twine 14, it is an elongated tubular that forms with the stacked coiling of carbon fibre fabric plate of the pre-epoxy resin dipping of multilayer, one connects throat's 18, one wooden handles 20 of this ring frame 12 and this footstalk 16, is fixed in the open end of this footstalk 16, and a taper upper shield 22, be socketed on the junction of this handle 20 and this footstalk 16.

This ring frame 12 has orthogonal major axis X-X ' and minor axis Y-Y ', its two relative open end 121,122 is positioned at one of this major axis X-X ' end, when this throat 18 of moulding, earlier end 161 on this two relative open end 121,122 and this footstalk 16 is converged, take many pre-epoxy resin dippings then but still unhardened carbon fibre fabric plate is reeled in regular turn and is coated on aforesaid meet, through the heating pressurization, make this coating be this throat 18 in the last die cavity of again this meet being inserted a mould together with this coating by die cavity shape hardened forming.

Hence one can see that, the throat 18 of the utility model racket 10 promptly was coated on the meet of ring frame and footstalk in advance before unhardened moulding still, therefore the more traditional certainly T connector of tight ness rating that engages is good, and its thickness can optionally and in addition be controlled when reel coating, and does not therefore also have protruding rank portion in the junction and produces.

See also Fig. 3 again, racket 30 its throats 32 of another embodiment of the utility model are except that including a multilayer shape coating 34, also include a heart 36, this heart 36 has three branches 361,362 and 363, during manufacturing, earlier aforementioned each branch is intercalated in the inside of 38 liang of relative open ends 381,382 of ring frame and the inside of footstalk 40 upper ends 402 respectively, and then this coating 34 of reeling, like this, can make this throat 32 have preferable anti-stress ability.

At last, see also Fig. 4, the racket 50 of the another embodiment of the utility model, except throat 52 with multilayer shape coating, also has a handle 54 that is shaped in footstalk 56 ends, the external diameter of this handle 54 forms horn-like 58 greatly and in the junction with this footstalk 56 than this footstalk 56, and this outer this footstalk 56 without leave of horn-like 58 increases gradually toward these handles 54, in order to replace the taper upper shield of traditional shuttle bat.
