Abstract

The improved tennis racket has the frame width, the frame thickness and the frame shape of the frame forming each part in the design of staggered change, can effectively play a role in shock absorption, simultaneously increases the hitting strength, reduces the amplitude of the racket during hitting, and ensures that the hitting power is large and the ball path is stable.

Description

The utility model relates to a tennis racket, in particular to a racket structure with excellent shock-absorbing effect and strength, which can reduce the hitting amplitude of the racket, increase the hitting power and stabilize the ball path.

The tennis racket adopted in the prior art is generally as shown in FIG. 1 . It is to thread and interweave a thread with a predetermined tension on the frame of the racket. Due to the effect of the tension of the thread, the thread and the frame of the racket form an integral structural relationship, and at the same time the head 10 of the entire racket. In terms of cross-section design at the frame 11 and the throats 12 on both sides, the width and thickness are the same. The tennis racket of this structure has following shortcoming. This kind of racket with roughly constant cross-section has poor shock absorption effect when hitting the ball, and the hitting force cannot be increased. The user is prone to muscle fatigue in addition to more effort, which is the vibration caused by the net cable after hitting the ball. The energy is completely transmitted to the racket frame through the thread, and then absorbed by the player's hand. Therefore, the elbow of the tennis player who has been exercising for a long time causes serious sports injuries, and often has the so-called "tennis elbow" disease. In addition, the width and thickness of the throat of the racket are designed to be the same as that of the entire racket. The vibration amplitude generated when hitting the ball will be relatively large. The power is weaker, resulting in shortcomings in use. In order to increase the shock-absorbing effect, in the prior art, there are shock-absorbing elements such as plastics added to the aluminum racket, but there are also disadvantages such as poor strength and limited shock-absorbing ability, and the shock-absorbing elements cannot be completely fixed, resulting in threading holes on it. It cannot be aligned with the threading hole of the racket frame, which also brings a lot of inconvenience to the making of the racket frame.

The purpose of this utility model is to overcome the deficiencies in the above-mentioned prior art, to provide a kind of can effectively increase the shock-absorbing effect and strength of the whole ball frame, can reduce the strike amplitude of the racket at the same time, can stabilize the ball path and increase the power of hitting the ball. Tennis racket design.

The purpose of the above invention is achieved through the following technical solutions. A tennis racket, which is composed of a head, a frame, a throat, and a frame composed of racket frames on both sides, and a handle, and is characterized in that the head has a large width and a small thickness; The frame is composed of a small arc-shaped frame with a large thickness; the two sides are composed of a frame shape with a large width and a small thickness; the frames on both sides are each provided with a predetermined number of staggered reduced section parts 25 and enlarged sections. The cross-section part 24, wherein the cross-sectional shape change from the small cross-section part 25 to the large cross-section part 24 is gradually enlarged, while the cross-sectional shape change from the large cross-section part 24 to the small cross-section part 25 is gradually reduced, and the frames on both sides of the center line are opposite to each other. The position is thick and thin opposite and symmetrical to each other. The racket frames with different widths and thicknesses on both sides of the center line transmit the generated vibrations to the handle and cancel each other to avoid damage to the user.

The tennis racket of the present utility model will be further described below with reference to the embodiments described in the accompanying drawings.

Referring to Fig. 2, 4, 6, according to the tennis racket of the present utility model, the cross-sectional shape of the racket frame is structurally improved. The racket head 20, the width and thickness of the frame 21 and the throat 22 are designed to be varied, so that the throat 22 has a larger width and a smaller thickness, and the frame 21 is an arc-shaped frame design with a small width and a large thickness. The design can increase the effect of shock absorption by virtue of the enlarged space of the hollow body of the frame when hitting the ball. In addition, the inwardly convex design on both sides can increase the strength and strength of the ball; the 22 parts of the throat are designed with a small width and thickness It can reduce the amplitude of the racket when it hits, and at the same time reduce the contact time of the ball with the net surface to achieve stable hitting and increase the speed of the ball to give full play to the effect of hitting the ball.

The left racket frame portion 23 of the racket is provided with a predetermined number of enlarged cross-section parts 24a and narrow cross-section parts 25b arranged in a staggered manner. As in the first embodiment (Fig. 3) of the utility model, an enlarged cross-section part 24 and a reduced cross-section part 25 are provided on the left frame part 23; and in the second and third embodiments (see Fig. 5 and Fig. 7) are respectively provided with three enlarged cross-section parts 24 and three narrowed cross-section parts 25 on the racket frame part 23, among which the first enlarged cross-section part 24a is located at the top, which extends downward along the racket frame and has a cross-section Gradually narrow until the first narrowed section 25a, and continue to extend downwards from the narrowed section 25a, and the cross section gradually expands to the second cross section 24a', and then alternately change downwards sequentially. Therefore, when the top of the self-portrait extends downwards, its cross-section changes in a section that gradually shrinks from large to small.

Correspondingly on the right racket frame part 23, from top to bottom are the first reduced cross-section part 25b, the first enlarged cross-section part 24b, the second reduced cross-section part 25b', and the second enlarged cross-section part 24b' , the third narrowed section 25b", and the third enlarged section 24b", and its shape change is just opposite to that of the left racket frame 23, so the cross section changes from small to large from top to bottom progressively larger segments.

Due to the cross-section of the racket frame being opposite in thickness and symmetrical to each other, the resulting vibration can be transmitted to the handle to achieve a mutual offset effect to avoid sports injuries, and at the same time it has the effect of a solid structure and balanced force.

The racket material can be made of aluminum, or lightweight hard aluminum alloys and other materials.
