Description

Technical Field

[0001] The present invention relates to a device, in particular to a device for interfering with and buffering the recoil shock waves generated by the hitting of a ball / racket frame by a string, and reducing the shock waves transmitted to the wrist and arm through the racket. Background Art

[0002] For various rackets commonly used with vertical and horizontal (X-axis and Y-axis) strings threaded into the racket frame, the racket frame is mainly characterized by having approximately symmetrical vertical and horizontal string holes around the periphery, with a single nail installed 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 hitting sports such as tennis, badminton, and squash. In order to catch the ball landing in the sweet spot of the racket face, the athlete holding the racket must not only move quickly but also have continuity. More importantly, the racket frame's string and the ball will generate a recoil shock wave at the moment of hitting, which can cause numbness in the wrist and arm. The recoil force is proportional to the tension (i.e., tightness) of the string. The higher the tension, the greater the recoil force. This recoil force is transmitted along the racket to the wrist or arm, which can easily cause sports injuries such as backhand tennis elbow or forehand golf elbow. Because the string of existing rackets is woven between the strings of the racket frame and does not have any vibration reduction device, the recoil force shock wave generated by the ball hitting the racket face formed by the string cannot be absorbed and buffered, and is completely transmitted to the wrist and arm, making the racket grip unstable. In addition, the weight around the existing racket frame cannot be adjusted according to the user's needs, which greatly reduces its practicality. Summary of the Invention

[0003] In order to solve the above-mentioned shortcomings of the prior art, one purpose of the present invention is to provide a shock-absorbing device, the outer tube of which is formed by staggered integration of soft medium and hard medium and has an outer tube wall on the periphery, a fitting portion is formed at the bottom of the outer tube, and an inner tube is axially provided with a threading hole and has an inner tube wall to overcome the shortcomings of the prior art.

[0004] Another object of the present invention is to provide a shock-absorbing device that generates different directional weights through one or more devices installed on the periphery of the racket / ball frame. The device utilizes the perforations of the inner tube wall of the string sleeve adjacent to the racket / ball frame to provide interference at different time points and withstand the shock waves generated by the string hitting the ball, thereby achieving shock absorption and buffering.

[0005] Another object of the present invention is to provide a shock absorbing device that can effectively simplify the structure, improve the safety of the racket, ensure a stable grip, and reduce sports injuries.

[0006] To achieve the above-mentioned object, the present invention provides a shock absorbing device for use with a racket or ball frame having multiple holes or a single spike and providing a string threading mechanism. The device comprises:

[0007] At least one outer tube is provided on the periphery of the racket / ball frame between adjacent through holes, and the outer side and the outer side of the outer tube respectively have a fitting surface and an outer tube wall, and the bottom of the outer tube forms a fitting portion for fitting on the periphery of the racket / ball frame;

[0009] By providing more than one device between adjacent holes of the ball / racket frame, the weights on different sides are used to suppress the non-horizontal plane of the net line, provide interference at different time points, and withstand the shock wave generated by the net line hitting the ball, thereby achieving shock absorption and buffering.

[0010] In the present invention, the outer cylinder is in a circular, square or polygonal shape.

[0011] The outer cylinder of the present invention comprises a soft medium and a hard medium which are staggered and integrally formed.

[0012] In the present invention, the outer cylinder and the inner cylinder are cut into a hollow array.

[0013] In the present invention, an angle is formed between the horizontal upper ends of the outer tube and the inner tube, and at least one counterweight is provided to achieve shock absorption through a rotation angle.

[0014] Wherein, the outer wall of the outer tube of the present invention is a rough surface or a textured surface.

[0017] Wherein, the inner cylinder wall of the inner cylinder of the present invention is an irregular surface.

[0018] Wherein, the outer tube wall of the outer tube and the inner tube wall of the inner tube of the present invention are irregular surfaces.

[0019] In the present invention, the radial distance ratios of the fitting portions between the upper end of the inner tube and the upper end of the outer tube wall of the outer tube and between the lower end of the inner tube and the bottom of the outer tube are 1:1 or 1:2.

[0020] In the present invention, the outer cylinder is provided with at least one hole arranged in an axial direction between the outer cylinder, the inner cylinder and the fitting portion in a radial direction.

[0021] The outer cylinder of the present invention is shaped like a column, a left-handed column, a right-handed column, or a spiral column formed by combining at least one group of left-handed column and right-handed column.

[0022] Compared with the prior art, the present invention provides a shock-absorbing device, wherein the outer tube of the device is formed by staggered integration of soft and hard media and has an outer tube wall on the periphery. The bottom of the outer tube is formed with a fitting portion, and the outer tube is axially provided with an inner tube serving as a threading hole and has the inner tube wall. Thus, different directional weights are generated by one or more of the devices being arranged on the periphery of the ball / racket frame. The string is threaded through the adjacent holes of the inner tube wall provided on the ball / racket frame to provide interference at different time points and withstand the recoil force and shock waves generated by the string hitting the ball, thereby achieving shock absorption and buffering. This effectively improves the structural simplification, ensures the safety of the racket, ensures the stability of the grip, and reduces sports injuries, which will greatly expand the industrial applicability.
