Abstract

The utility model relates to a racket for tennis. The frame width, frame thick and frame mode which are composed of each part of the frame adopt interleaving and varying design, effectively having vibration damping effect, simultaneously increasing strength of driving balls, decreasing amplitude of the racket when the racket drives balls, and making the driving ball force be great and the ball road be stable.

Description

Racket for tennis

The utility model relates to a kind of tennis racket, and particularly a kind of have good shock-proof effect and intensity, and can reduce the amplitude that racket hits, and promotes strength of batting and can stablize the racket structure of course of action.

Tennis racket used in the prior art generally as shown in Figure 1.Be the line of on its frame, wearing around the predetermined tension that interweaves, form an integrally-built relation owing to the effect of line tension makes line and frame, simultaneously the head 10 of whole racket.On the Cross section Design at frame 11 and both sides throat 12 places, its width is all identical with thickness.The tennis racket of this structure has following shortcoming.The shock-proof effect of batting was not good during the constant racket in this roughly cross section used, striking force can not get increasing, the user is except that being easy to generate muscular fatigue the effort, just netting twine passes on the frame through the complete warp of vibration energy that a square stance is caused, hand by the sporter absorbs again, so the tennis player's of prolonged motion the elbow of clapping hands of holding causes serious motional injury, and the illness of what is called " tennis elbow " is often arranged.Racket throat in addition, both sides width and Thickness Design are identical with whole racket, and the amplitude that square stance produced can be bigger, and except that meeting produced the batting shakiness, the strength of batting also can't be brought into play fully, and the strength during backhand is more weak, causes the shortcoming in the use.For increasing shock-absorbing effect, have in the prior art and on the aluminum racket, add by such as plastics class shock absorber, but shortcomings such as intensity is not good, damping capaicty is limited are arranged also, and shock absorber also can't be completely fixed, cause the through wires hole on it can't align, also bring inconvenience for the making of frame with the through wires hole of frame.

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of shock-absorbing effect and intensity that can effectively increase whole ball frame is provided, and can reduce the strike amplitude of racket simultaneously and can stablize course of action and a kind of tennis racket design of increase striking force.

The purpose of foregoing invention is achieved by the following technical programs.A kind of tennis racket is made up of frame portion and handle that head, frame, throat and both sides frame are formed, and the width that it is characterized by described head is big and thickness is less; The described frame arc frame that thickness is bigger so that width is less constitutes; The less shaped as frame of thickness constitutes so that width is big in described both sides; Described both sides frame respectively is provided with predetermined number and is staggered section parts 25 and the enlarged cross section position 24 of dwindling, wherein the variation of 24 cross sectional shape is expansion gradually from small bore position 25 to the position, heavy in section, and the cross sectional shape from position, heavy in section 24 to small bore position 25 changes to be and dwindles gradually, and center line both sides frame relative position is to be the opposite and symmetry mutually of thickness.The vibration that relies on the frame of the different width thickness in center line both sides to produce reaches handle and partly cancels out each other and avoid the user is caused damage to reach.

Embodiment below with reference to description of drawings is further described tennis racket of the present utility model.

Fig. 1 is the schematic perspective view of tennis racket in the prior art;

Fig. 2 is the front view according to an embodiment of the present utility model;

Fig. 3 is the side view of Fig. 2 racket;

Fig. 4 is the front elevational schematic of another embodiment;

Fig. 5 is the left and right sides view of Fig. 4 racket;

Fig. 6 is the schematic perspective view of another embodiment;

Fig. 7 is the schematic diagram that racket shown in Figure 6 partly launches along left and right sides frame.

Referring to Fig. 2,4,6,, be that racquet frame portion section type body is carried out structural improvement according to tennis racket of the present utility model.Racket head 20, the width at places such as frame 21 and throat 22, the design that thickness is made variation, make throat's 22 width big and thickness is less, 21 on frame is the big camber frame design of the little thickness of width, rely on above-mentioned design can increase the effect of its shock-absorbing at square stance with the space of its framework ducted body increasing, the design of its both sides convex can increase batting intensity and dynamics in addition; Amplitude when throat 22 sentences width and thickness little design can minimizing racket and hits, reduce simultaneously time that ball contact with wire side reach stable and bat, increase ball speed to be to give full play to the effect of playing ball.

The left side frame part 23 of described racket, be provided with predetermined number and be to be staggered enlarged cross section position 24a and to dwindle section parts 25b.As being exactly on frame position, left side 23, to be provided with an enlarged cross section position 24 and one to dwindle section parts 25 at first embodiment of the present utility model (Fig. 3); Then on frame position 23, respectively be provided with three enlarged cross section positions 24 and three at second and third embodiment (seeing Fig. 5 and Fig. 7) and dwindle section parts 25, that wherein be positioned at the top is the first enlarged cross section position 24a, it is for extending downwards along frame and the cross section dwindles gradually until first and dwindles section parts 25a, and continue to dwindle that section parts 25a extends downwards and the cross section is extended to second section parts 24a ' gradually, sequentially staggered according to this variation downwards by this.Therefore downward its changes of section of extending in top of autodyning all is the section that dwindles gradually from large to small.

Accordingly at frame position, right side 23, dwindle section parts 25b for first in regular turn from top to bottom, first enlarged cross section position 24b, second is dwindled section parts 25b ', second enlarged cross section position 24b ', the 3rd is dwindled section parts 25b ", the 3rd enlarged cross section position 24b ", and its change of shape is proper and frame position, left side 23 is inverse state, and therefore its changes of section of top-down extension all is by little to the big section that enlarges gradually.

Rely on above-mentioned frame of racket cross section to be the opposite and symmetry mutually of thickness, can have when reaching handle portion to reach the effect of cancelling out each other,, have sturdy construction simultaneously and make the effect of stress equalization to avoid injury gained in sports by the vibrations that produce.

The racket material can adopt aluminium matter, or the materials such as dualumin alloy of lightweight are made.

Claims (2)

1, a kind of tennis racket is made up of frame portion and handle that head, frame, throat and both sides frame are formed, and the width that it is characterized by wherein said head 20 is big and thickness is less; The described frame 21 arc frame that thickness is bigger so that width is less constitutes; The less shaped as frame of thickness constitutes so that width is big in described throat 22; Described two frames 23 respectively are provided with predetermined number and are staggered section parts 25 and the enlarged cross section position 24 of dwindling, wherein the variation of 24 cross sectional shape is expansion gradually from small bore position 25 to the position, heavy in section, and the cross sectional shape from position, heavy in section 24 to small bore position 25 changes to be and dwindles gradually, and center line both sides frame relative position is to be the opposite and symmetry mutually of thickness.

2,, it is characterized by its material and can adopt aluminium matter alloy according to the tennis racket of claim 1.
