Abstract

The utility model discloses an improved structure for tennis rackets, which is composed of a framework, a racket surface, and a handle, wherein, the framework and the handle which is connected to a lateral extension base pin of the framework are non-integral structures; the handle is sheathed on the base pin by adhesive and rivets. Because the thickness of PU foamed plastics can be thinned or the PU foamed plastics are not needed by enlarging the outer diameter and the shape of hollow and tubular section materials for making the handle, thereby, the weight of the handle is lightened.

Description

Tennis racket improves structure

The utility model relates to a kind of structure of tennis racket, particularly relates to the lighter tennis racket of a kind of weight and improves structure.

Tennis is a kind of motion of doing of can continuing for a long time, even also can carry out this motion over 60 to 70 years old advanced age, no matter and men and women, old and young all can in this motion, obtain enjoyment.In recent years, alleviate the weight of tennis racket, the power lighter and don't the reduction batting that tennis racket is become is the desired target that reaches of each dealer.As shown in Figure 1 and Figure 2, known tennis racket be by face 1 ', dabber 2 ' and handle 3 ' constitute, handle 3 ' handengagabie portion, perfusion one deck PU foamed plastic 4 on it ', be anistree shape, the handle 3 of this structure ' with dabber 2 ' be one, be handle 3 ' be dabber 2 ' the edge stretch portion, because dabber 2 ' thinner relatively, foamed plastic is thicker, and weight is also with regard to corresponding increase.

The purpose of this utility model just provides the lighter tennis racket of a kind of handle weight and improves structure.

In order to achieve the above object, the utility model tennis racket improves structure, comprises that netting twine places strike face, frame and the handle that forms.Frame is to be made of head frame that can supply netting twine to place and the pin that extends laterally along described head frame, and handle is connected on the described pin; The frame of tennis racket adopts aluminum alloy materials or magnesium alloy materials.Described frame is non-integrative-structure with the handle that is connected on the frame pin, this handle is the hollow tubular section bar, the handle cross section of this tubulose section bar is slightly larger than the cross section of pin, and the cross section of handle and pin connecting portion and the cross section of pin adapt, and the handle of tubulose section bar is socketed on the pin by viscose glue and rivet.

Because the utility model can subtract the thickness of book PU foamed plastic or need not the PU foamed plastic, thereby alleviate the weight of handle by having increased the external diameter and the shape of making the hollow tubular section bar of handle.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

As Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, be first embodiment of the utility model.The utility model tennis racket improves structure and comprises that netting twine places strike face 1, frame 2 and the handle 3 that forms; Frame 2 is to be made of head frame 22 that can supply netting twine to place and the pin two 1 that extends laterally along described head frame 22, and handle 3 is connected on the described pin two 1.Perfusion one deck PU foamed plastic 4 on the handle 3, the frame 2 of tennis racket adopts aluminum alloy materials or magnesium alloy materials.Described frame 2 is non-integrative-structure with the handle 3 that is connected on framework 2 pin twos 1, this handle 3 is the hollow tubular section bar, handle 3 cross sections of this tubulose section bar are slightly larger than the cross section of pin two 1, and handle 3 adapts with the cross section of pin two 1 connecting portion 31 and the cross section of pin two 1, the surface process sandblast and the cleaning of pin two 1, and coat viscose glue, then, tubulose section bar handle 3 is socketed on the pin two 1, handle 3 and pin two 1 is fixed together by rivet 5.Handle 3 cross sections of the utility model hollow tubular section bar are oblong-shaped, after handle 3 and pin two 1 are riveted together, handle 3 placed pour into PU foamed plastic 4 in the mould, make handle 3 profiles form required octagonal structure, because the profile of handle 3 has accounted for most of volume of octagonal section, so used PU foamed plastic 4 amounts are less.

As Fig. 7, Fig. 8, Fig. 9, shown in Figure 10, be second embodiment of the utility model.Present embodiment and first example structure are basic identical, and institute's difference is: the handle 3A cross section of hollow tubular section bar is an octagonal, by the reducing operation make handle 3A make handle this section the cross section and the cross section of pin two 1 adapt.Because handle 3A cross section has been required octagonal, so need not handle 3A to be placed to pour into the PU foamed plastic in the mould, has save the PU foamed plastic again.

The tennis racket 10g-15g in light weight that its weight of tennis racket of employing the utility model structure can be commonly used, the difference of this weight is very tangible for tennis racket, simultaneously, because weight alleviates handle part, the position of centre of gravity of tennis racket is moved up, also move toward the racquet frame top slightly its batting center, hits power and can therefore not reduce.

In addition, as Fig. 3, Fig. 5, Fig. 7, shown in Figure 9, handle 3 of the present utility model and frame 2 can be put a plastic cement piece 6 by ejection formation by selecting different materials for use and disposing at the support 23 of frame 2, reach alleviate the racket vibration, reduce the purpose of power that racket reacts on people's arm.
