A new type of badminton racket with an adjustable shaft and balance point handle and a double-layer frame.

Abstract

This invention provides a novel badminton racket design, including an adjustable handle for shaft curvature and balance point, and a double-layered frame. The adjustable handle addresses the limitation of traditional badminton rackets in adjusting shaft stiffness and balance point, allowing users to fine-tune the racket to suitable parameters. The double-layered frame solves the problems of insufficient stability in traditional aerodynamic frames and slow swing speed in box-type frames.

Description

Technical Field

[0001] This invention relates to a novel badminton racket with an adjustable shaft and balance point handle, and a double-layered frame. Background Technology

[0002] This invention addresses the limitations of traditional badminton rackets in adjusting shaft stiffness and balance point, as well as the instability of the traditional aerodynamic frame and the slow swing speed of the box-shaped frame. Summary of the Invention

[0003] This invention proposes a novel badminton racket with an adjustable shaft and balance point handle, and a double-layered frame. Through modifications to traditional badminton rackets, this racket allows for adjustments to shaft stiffness and balance point, and solves the problems of insufficient stability in traditional racket frames and slow swing speed in box-type frames.

[0004] This invention aims to solve the aforementioned problems by providing a badminton racket design, including an adjustable handle for shaft curvature and balance point, and a double-layer frame. The adjustable handle comprises a knob, a balance adjustment group, and a shaft adjustment group. The double-layer frame provides a more stable structure and higher aerodynamic efficiency for the racket frame.

[0005] The aforementioned handle, which adjusts the curvature of the shaft and the balance point of the racket, is made of polymer material through hot melting, injection molding, blow molding, extrusion, or 3D printing processes, and then assembled.

[0006] The aforementioned double-layer frame is placed on one long side of a carbon fiber prepreg through a plastic shaping film tube. Half of the carbon fiber prepreg is rolled into a hollow tube, and a polymer material of a specific shape is placed inside, and then rolled into a tube shape again. The carbon fiber tube is then connected to the carbon fiber rod and placed into a mold for molding.

[0007] The double-layer frame has two additional different frame types, and it can combine the two frame types, a design that is not found in other badminton rackets.

[0008] The desired effect of this invention is to allow for personalized customization of badminton racket parameters and to achieve better racket frame hitting performance. Attached Figure Description

[0012] Example 1 This embodiment discloses a novel badminton racket, including an adjustable shaft and balance point handle, and a double-layer frame. The handle, which adjusts the shaft's curvature and balance point, allows adjustment of the shaft's stiffness by changing the connection point between the shaft and the upper part of the handle using a lower knob. Another knob at the lower part of the handle changes the position of the internal weight block, thus adjusting the racket's balance point. The double-layer frame consists of two specific frame layers and a polymer material in between.

[0013] In addition to the above embodiments, the present invention may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent replacement are within the protection scope claimed by the present invention.
