Abstract

The utility model relates to a grab handle of a racket, which is a columnar body. One end of the utility model is connected with the throat part of a racket, and the other end is sheathed with a back sleeve. An elastic cushion made of elastic material is arranged between the end connected with the throat par and the end with the back sleeve, while a grab handle belt is coated on the outer surface of the grab handle. An arc-shaped concave surface is arranged between the end connected with the throat part of the grab handle and the end with the back sleeve. The concave surface uses a holding point of a hand as a lowest point, while other parts of the grab handle are dented towards the lowest point. The elastic cushion is coated on the concave surface, whereas the inner wall of the elastic cushion protrudes inwards in order to be matched with the shape of the concave surface. Thus the elastic cushion has different section thicknesses, and the thickness of a hand holding part is maximum. The racket can efficiently improve shock absorption effect without increasing weight.

Description

Handle of racket

The utility model be about a kind of under the condition of unlikely increase racket weight, can promote the racket lever of racket damping effect effectively.

The damping of racket lever is to be the main flow in the racket vibration control structure now, and on the racket lever cushion of sheathed elastic material, general cost is minimum and be easy common technique;

Yet the cushion that generally has a preferable damping capaicty all has section thickness to a certain degree, not only causes the weight of whole racket to increase the weight of, and can cause the not good shortcoming of ball-handling of this racket; Opposite, though the less cushion of section thickness can improve the problem of racket weight and ball-handling property, its damping capaicty is limited, and effect is unclear.

As depicted in figs. 1 and 2, racket lever 1 commonly used, usually with its with the link 11 of racket throat 2 and its end that is provided with back cover 12 between the cushion 13 of a sheathed rubber material, and by the shaking force of these cushion 13 these rackets of absorption because of batting and being produced; But must be provided with several projections 14 and groove 15 between the fit face of this cushion 13 and lever 1, produce slippage at this cushion 13 of square stance and lever to avoid racket, thereby, make this lever 1 and cushion 13 comparatively difficult on making like this.

The purpose of this utility model is to provide a kind of racket lever, and this kind racket lever can not increase racket weight and influence racket ball-handling property, and makes simple and increase the damping effect of racket.

According to racket lever of the present utility model, this racket lever is a cylindrical body, the throat of one end and racket is connected, the then sheathed back cover of the other end, and at the link of this lever and throat be provided with and be provided with the cushion of elastic material between the end of back cover, and coat the outer surface of this lever with Handle strip;

It is characterized in that: the link of this racket lever and throat and be provided with between the end of back cover the concave face that is arcuation is arranged, and this concave face is to be minimum point according to the gripping point of hand, and caves in to this minimum point place at the link of racket lever and throat and the other parts that are provided with between the end of back cover; In addition, cushion is coated on this concave face and its inwall is to cooperate the concave face shape to projecting inward, so that this cushion has different section thicknesses and be maximum with the thickness of the grip part of hand.

Now describe the utility model in detail with reference to following each drawings and Examples, in these accompanying drawings:

Figure 11 is the assembled sectional view of Figure 10.

Figure 12 is the cross-sectional schematic of the utility model the 4th embodiment.

See also Fig. 4,5, the racket lever 2 of this embodiment is an octagonal column body greatly most, the throat 3 of one end and racket is connected, the then sheathed back cover 21 of the other end, and at the link 22 of this lever 2 and throat 3 be provided with and be equipped with PU foaming body 23 between the end of back cover 21, be with the cushion 24 of rubber material on the outer surface of this PU foaming body 23, and coat the outer surface of this lever 2 with Handle strip 25;

See also Fig. 6, the link 22 of this racket lever 2 and throat 3 and be provided with between the end of back cover 21 concave face that is the arcuation depression from two ends to central part is arranged, and also this concave face is that gripping point according to hand is a minimum point; In addition, cushion 24 is coated on this concave face, and its inwall is to cooperate the concave face shape and to projecting inward, make this cushion 24 have different section thicknesses like this, and with the grip part thickness maximum of hand.

The structure of above-mentioned Fig. 6 can make these cushion 24 thickness maximums have preferable damping effect, and because general user has the custom of swinging the bat of oneself, its gripping for racket also all has certain gripping point, so the remainder of this cushion 24 since when swinging the bat hand can not hold and, and thickness can be thinner, to save manufactured materials and to alleviate the overall weight of racket.

In addition, the cambered surface combination of this cushion 24 and lever 2 concave faces can make such combination very firm, thereby makes this racket 2 at the square stance of swinging the bat, axial slip (shown in Fig. 7,8) can not take place radially to reach in 24 of concave face and cushions, is beneficial to the ball-handling mode of this racket 2.

See also Fig. 9, racket lever 4 of the present utility model, its cushion 41 also can be the cushion of upper and lower two symmetries, and they directly are incorporated on the concave face 42 of lever 4 relatively, are beneficial to the combination assembling of this lever 4.

See also Figure 10,11, racket lever 5 of the present utility model, its cushion 51 also can be integrally formed with back cover, and directly are inserted in by the tail end of lever 5 when assembling.Like this, not only can simplify the assembling of this lever 5, and can when this racket lands accidentally, can protect the tail end of lever 5 effectively.In addition, the cambered surface combination of this cushion 51 and concave face can make this racket at the square stance of swinging the bat, and these cushion 51 unlikely tail ends from lever 5 skid off.

Because user's the custom of swinging the bat is different, for the gripping point of racket lever difference is arranged also, so racket lever of the present utility model, the design of its concave face can be done multiple variation, to be applicable to more user.

As shown in figure 12, among this embodiment, the surface that is sheathed on the cushion 61 on lever 6 surfaces also can be suitable cambered surface recess, grips to be more convenient for.

Below only the mat preferred embodiment describes the utility model in detail, does not break away from spirit and scope of the present utility model for any simple modification and the change that above embodiment did.

Design of the present utility model is smart will to be that the inventor observes general user in a subtle way for the use habit of racket, thereby in the design of racket lever, historical facts or anecdotes is a rare design in conjunction with its habit.
