The present invention relates to a sport ball equipment tool, and more particularly to shock absorbing structure of a racket which includes a handle, a connection tube, and a frame.
For ball sports such as tennis, badminton, and squash that use hollow tubular handles, rods, or frames as rackets, the main action is to accurately hit the ball back. However, if the racket produces too much vibration when hitting the ball, it will cause unstable ball control and easily cause sports injuries to the hands.
To reduce the vibration, many improvements are made on the frame or handle of the racket, and the method of hanging the shock absorber is often used, such as setting a groove in the frame of the racket, inserting a shock absorbing block in the groove, or a network cable around the frame of the racket There are methods such as hanging shock absorbers. However, the shock absorber cannot be firmly fixed, and it is easy to fall due to the shock. If it is not installed properly, it will not only increase the weight of the racket, but may also change its center of gravity, resulting in poor handling. In addition, the effect of the external shock absorber is not satisfactory, and it cannot really effectively reduce the powerful impact force at the moment of hitting the ball.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a shock absorbing structure of a racket which is capable of overcoming the shortcomings of the conventional shock absorbing structure of the racket.
To obtain above-mentioned objective, a shock absorbing structure of a racket provided by the present invention contains: a head and an absorption member matingly contacting with an internal fence of the head. The absorption member is a hollowly tubular structure and covers the internal fence totally.
When the head is made of carbon-fiber composite material, the absorption member is made of any one of Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU).
When the head is made of metal or aluminum alloy, the absorption member is made of any one of Thermosetting Elastomers, Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU).
The absorption member matingly contacts with the internal fence of the heat, thus avoiding a removal of the absorption member and enhancing reinforcement of the racket.
When the head and the absorption member are made of different materials, an amplitude of the head is different from an amplitude of the absorption member, and the head interferes the absorption member, thus absorbing vibration.
With reference to
The tennis racket 10 includes a handle 11, a connection tube 12, and a frame 13 which are tubular and are configured to define and surround the head 20, wherein the head 20 includes an absorption member 30 matingly contacting with an internal fence 21 of the head 20. Referring to
When the head 20 is made of carbon-fiber composite material, the absorption member 30 is made of any one of Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head 20 is made of metal or aluminum alloy, the absorption member 30 is made of any one of Thermosetting Elastomers, Thermoplastic Elastomer (TPE), Thermoplastic Rubber (TPR), rubber, Hydrogel, and Thermoplastic Polyurethane (TPU). When the head 20 and the absorption member 30 are made of different materials, an amplitude of the head 20 is different from an amplitude of the absorption member 30, and the head 20 interferes the absorption member 30, thus absorption vibration.
While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
