Abstract
The invention provides a racket. The racket comprises a frame, a middle tube and a handle, wherein one end of the middle tube is fixedly connected with the handle; the other end of the middle tube is connected with the throat part of the frame; the frame further includes a first bending part and a second bending part symmetrical to each other on the left side and the right side of the throat part; and the vertex of the throat part is closer to the inner part of the frame than that of the first bending part and the second bending part. The position of the sweet area of the racket can shift upwards by hoisting the position of the throat part, thereby improving the striking force.
Description
Technical field
The invention belongs to the sports apparatus field, particularly a kind of sport racket.
Background technology
The frame of the rackets such as racket, tennis racket, wall ball racket is in order to twine and the fixing line of clapping, to use the formation hitting area.Happy district is the most effective hitting area of racket face, and happy district can give the enough powers of striker, ball-handling property and sturdy batting.When the striker bats with happy district, will feel very comfortable, experience very little concussion and vibrations, and can be delivered to striking force on the spheroid by the sweetness district fully.Therefore, size and the position in happy district are very important for the what racket, and it can make the striker more easily get high-quality ball.
Yet, length and width size for rackets such as racket, tennis racket, wall ball rackets, strict restriction is arranged, for example with racket, racket length can not surpass 680mm, frame length can not surpass 290mm, width can not surpass 230mm, and the face width that the face length of the interior threading of frame can not surpass 280mm, threading can not surpass 220mm.Suchlike restriction is so that there are technical bottleneck in the comfort level that effectively promotes racket, happy district in present most factories, related scientific research mechanism with the problem of attack, and haves much room for improvement.
Summary of the invention
In order to solve the desirable not to the utmost part of aforementioned prior art, the invention provides a kind of racket, include frame, middle pipe and handle, wherein, one end of middle pipe is solidly connected to handle, and the other end of middle pipe is connected to the throat of frame, it is characterized in that: the left and right sides of the throat of frame further comprises the first bend and the second bend, the first bend and the second bend are symmetrical each other, and the summit of throat is than the inside of the more close frame in summit of the first bend and the second bend.
Above-mentioned racket, in a preferred embodiment, the first bend and the second bend respectively comprise the first circular arc and the second circular arc, and proper position, the summit of the first bend and the second bend is on the first circular arc and the second circular arc, and the center of curvature of the first circular arc and the second circular arc is in the inside of frame.
Above-mentioned racket, in a preferred embodiment, the throat of frame further comprises three-arc, and proper position, the summit of throat is on three-arc, and the center of curvature of three-arc is in the outside of frame.
Above-mentioned racket, in a preferred embodiment, the throat of frame further comprises a horizontal linear section, and proper position, the summit of throat is on the horizontal linear section.
The present invention can improve the position of throat by said structure, so that move in the happy district of batting, and do not affect the size in happy district, therefore can increase the batting power.

The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.Owing to the invention discloses a kind of racket, wherein employed correlation technique and relative configurations principle have been that those of ordinary skills can understand, therefore with hereinafter explanation, no longer do complete description.Simultaneously, with the accompanying drawing that is hereinafter contrasted, be intended to express the implication with feature related structure of the present invention, also do not need according to the complete drafting of actual size, formerly statement.
As shown in Figure 1, racket provided by the invention can be racket, tennis racket or wall ball racket, includes frame 1, middle pipe 2 and handle 3.One end 21 of middle pipe 2 is solidly connected to handle 3, and the other end 22 of middle pipe 2 is connected to the throat 11 of frame 1.
Please refer to Fig. 2, the left and right sides of the throat 11 of frame 1 further comprises the first bend 12 and the second bend 13, the first bend 12 and the second bend 13 are symmetrical each other, and the inside 14 of the summit 131 more close frames 1 of the summit 121 of summit 111 to the first bends 12 of throat and the second bend 13.
In a preferred embodiment, the first bend 12 comprises the first circular arc 122, the second bend 13 comprises the second circular arc 132, the summit 121 of the first bend 12 and the second bend 13,131 just the position on the first circular arc 122 and the second circular arc 132, and the center of curvature 123 of the first circular arc 122 and the second circular arc 132,133 inside 14 at frame 1.Certainly, by the more calculating of advanced method, finite element method (FEM) (Finite Element Method) for example, the first bend 12 and the second bend 13 also can be other curves, such as cycloid, curve, sine,, etc., do not limited at this.
In another preferred embodiment, the throat 11 of frame 1 further can comprise three-arc 112, and the 111 proper positions, summit of throat 11 are on three-arc 112, and the center of curvature 113 of three-arc 112 is in the outside of frame 1.
In another preferred embodiment, the throat 11 of frame 1 also can further comprise a horizontal linear section 114, and the 111 proper positions, summit of throat 11 are on this horizontal linear section 114.
The present invention can improve the position of throat 11 by said structure under the restriction that does not change racket length and width, so that the length of middle pipe 2 increases, batting moves in the happy district, and does not affect the size in happy district, therefore can increase the batting power.
The above only is preferred embodiment of the present invention, is not the interest field that limits the present patent application; Simultaneously above description should understand and enforcement for those of ordinary skills, so other does not break away from the equivalence of finishing under the disclosed spirit and change or modify, and all should be contained in the scope of claims.
