Description

Racket shock absorber

This creation is about a shock-absorbing device, specifically a racket shock-absorbing device that interferes with the recoil force shock waves generated by the racket surface and the ball hitting the racket, absorbs the shock and reduces the shock waves transmitted to the wrist and arm through the racket, and adjusts the racket weight according to actual needs.

According to general practice, various rackets are provided with vertical and horizontal (X-axis and Y-axis) strings on the racket frame. The racket frame is mainly provided with roughly symmetrical vertical and horizontal string holes around it. A single nail is provided in the string hole. The string is inserted into the single nail and woven into a racket face with a certain poundage. The racket frame with the string is used in extremely intense ball-striking sports, such as tennis, badminton, and squash. In order to catch the ball falling into the sweet spot of the racket face, the athlete holding the racket not only needs to move quickly, but also needs to have continuity. More importantly, the racket frame's string and the ball will generate a recoil shock wave at the moment of hitting, which will make the wrist and arm feel numb. The recoil is also related to the string. The tension of the string is proportional to the poundage (i.e., tightness). The higher the poundage, the greater the recoil force. The recoil force will be transmitted along the racket to the wrist or arm, which can easily cause sports injuries such as backhand tennis elbow or forehand golf elbow. Since the conventional racket is woven between the strings of the racket frame, it does not have any vibration reduction device. Therefore, the recoil force shock wave generated by the racket face formed by the ball and the string cannot be absorbed and buffered, but is completely transmitted to the wrist and arm, making the grip of the racket unstable. In addition, the weight around the conventional racket frame cannot be adjusted according to the needs of the user, which greatly reduces its practicality. This is what technical personnel and consumers in this field are eager to break through.

In order to solve the above-mentioned shortcomings of the existing technology, the main purpose of this invention is to provide a racket shock-absorbing device, which is provided with a lower seat and an upper pad. The lower seat has a convex block and a concave groove. The upper pad is arranged at the upper end of the lower seat or the upper end of the upper pad of other units. The upper pad is provided with a concave buckle groove corresponding to the convex block of the lower seat. The lower seat is provided with side edges on both sides and has rope through holes. The convex block is provided with an open counterweight groove with a counterweight block, so as to overcome the difficulties in the existing technology.

The secondary purpose of this invention is to provide a racket shock-absorbing device, which uses a shock-absorbing device including a lower seat and an upper pad to be set between two single nails of the racket frame, and provides interference and bearing of the shock wave of the recoil force generated by the ball hitting the net at different time points to achieve shock absorption and cushioning, and the racket weight can be adjusted according to actual needs.

Another purpose of this invention is to provide a racket shock-absorbing device to effectively improve the racket's safety, grip stability and reduce sports injuries.

The problem that this invention aims to solve is that according to the commonly used various rackets with vertical and horizontal (X-axis and Y-axis) strings inserted into the racket frame, the racket frame is mainly provided with roughly symmetrical vertical and horizontal string holes around it, and a single nail is provided in the string hole. The string is inserted into the single nail and woven into a racket face with a certain poundage. The racket frame's string and the ball will generate a recoil shock wave at the moment of hitting. The recoil force is also proportional to the poundage of the string. The higher the poundage, the greater the recoil force. The shock waves will be transmitted to the wrist or arm along the racket, which can easily cause sports injuries such as tennis elbow in the backhand or golf elbow in the forehand. In addition, since the conventional racket is woven between the wires of the racket frame, there is no device to reduce vibration. The shock waves generated by the recoil force and the racket face cannot be absorbed and buffered, but are completely transmitted to the wrist and arm, making the grip of the racket unstable. In addition, the weight around the conventional racket frame cannot be adjusted according to the needs of the user, which greatly reduces its practicality.

To achieve the above-mentioned purpose, the invention provides a racket shock-absorbing device, which includes: a lower seat body, which is arranged around the racket frame and has a string inserted between two single nails provided in the threading hole, and one or more protrusions corresponding to the direction around the racket frame are provided at the upper end of the lower seat body, and the one or more protrusions are adjacent to the lower seat body and a groove is provided at the center; at least one upper pad is arranged at the upper end of the lower seat body, and one or more concave buckle grooves are provided inside the upper pad body and correspond to the one or more protrusions of the lower seat body.
