Description

Vibration-damping handle structure of badminton racket

Technical Field

The application relates to a structure of a badminton racket, in particular to a vibration reduction handle structure of the badminton racket.

Background

The structural composition of the badminton racket comprises: the three parts of the head frame, the middle tube and the handle are connected with each other through the middle tube, so that the striking face is formed by threading the head frame. The traditional badminton racket handle is usually made of tough and difficult-to-break wood, and the consideration factor of selecting the wood to make the badminton racket handle is that the wood is easy to obtain, easy to process and low in price, and besides the wood has a good damping effect, so that the wood is helpful for absorbing vibration generated when the racket is hit.

In order to reduce vibration generated when the racket hits the ball, in addition to selecting wood to manufacture the racket handle, another mode is to wind handle cloth on the outer side of the racket handle, the handle cloth can absorb vibration through elasticity of the material, and other functions of the handle cloth also include: the thickness of the badminton racket handle can be adjusted, even the balance point of the badminton racket is slightly changed, the comfort during holding is improved, sweat is absorbed, and the anti-slip effect is provided. Common handle cloth can be basically divided into PU handle cloth and towel handle cloth according to the difference of materials. The traditional handle cloth is wrapped outside the handle in a winding way after the manufacture of the handle, particularly the whole badminton racket is finished, and cannot be reliably fixed on the handle, after the handle is used for a period of time, the handle cloth has the problems of loosening, peculiar smell generation or abrasion due to sweat or other external factors, and even the handle made of wood can be deteriorated or damaged due to the penetration of the sweat; on the other hand, the replacement of the handle cloth takes a long time, and is inconvenient to use.

In the approved taiwan patent application (certificate number I772198), a badminton racket is proposed, which comprises a frame, a handle, a front cover and a middle tube. The grab handle comprises a holding part, a sleeving part, a fixing piece, a plurality of supporting pieces and an adjusting ring. The holding part is provided with a front end. The sleeving part is connected to the front end of the holding part. The sleeving part is provided with a first top surface and a first opening, and the first opening is positioned on the first top surface. The fixing piece is connected to the first top surface and extends from the first opening to the inside of the holding part. The supporting pieces are arranged in the grab handle. The supporting members are respectively provided with a front edge and a concave part. The front edge is connected with an inner side wall of the sleeving part, and the concave part is positioned at the front edge. The adjusting ring is arranged in the concave parts of the supporting pieces. The front sleeve is sleeved on the sleeve part of the grab handle. One end of the middle tube is connected to the racket frame, and the other end of the middle tube passes through the first opening to be inserted into the fixing piece.

However, the middle tube of the above patent is inserted into the sleeve portion; the supporting pieces are arranged on the grab handle part, the front edges of the supporting pieces are connected to the inner side wall of the sleeved part, when an hit badminton directly hits the batting surface, the impact force is transmitted through the middle pipe, the supporting pieces can disperse the impact force, but cannot achieve the effects of shock absorption or absorption, and the impact can cause discomfort of the palm and the arm.

On the other hand, the sleeved part, the plurality of supporting pieces and the grab handle part are made of the same plastic material integrally, if the material is hard, such as adding carbon fiber, the whole racket is too hard and has insufficient elastic coefficient, besides the grab handle part has poor grab feel, can not only resonate or vibrate to generate discomfort, but also is easy to break and has poor durability; if the material is soft, such as nylon plastic, the rigidity of the whole racket is insufficient, the batting force can not be effectively released, the structural strength is insufficient, the rotation direction control of the racket face angle is not solid, and the performance of the back batting is further affected.
