Description

BACKGROUND

Technical Field

The present disclosure relates to a device and more particularly to a pad structure that can filter out specific amplitude of a racket frame and a string or enhance or comply with specific pound of force.

Description of Related Art

Various traditional rackets generally come with vertical and horizontal (X-axis and Y-axis) strings on their racket frame. The racket frames are mainly provided with substantially symmetrical vertical and horizontal threading holes around them, and the single nails are installed in the threading holes and the string is passed into the single nail and woven into a racket surface with a certain pound of force, and the racket frame with string constitutes the racket provided for a very intense hitting sport such as tennis, badminton, racket ball, etc. In order to catch the ball falling into the sweet spot of the racket, the athlete holding the racket not only needs to move quickly, but also needs to have continuity. More importantly, the string of the racket frame and the ball produce shock waves at the moment of hitting, which will make the athlete's wrist and arm feel numb, wherein the anti-shock force is proportional to the pound of force (i.e. tightness) of the string tension, and the higher the pound of force, the greater the anti-vibration force, and the anti-vibration force will be transmitted along the racket to the wrist or arm which may easily cause sports injuries such as tennis elbow caused by backhand swings or golf elbow symptom caused by forehand swings. Since the conventional racket is woven with the string of the racket frame, although related manufacturers have developed devices to reduce vibration, the shock generated by the slap of the racket surface and the ball and string can be absorbed and buffered and completely transmitted to the wrist and arm to allow the racket to be held stably, and adjust the weight around the racket frame according to the athlete's needs, yet the specific amplitudes of the racket frame and the string are fixed and cannot be fine-tuned and filtered out to enhance or comply with a certain pound force. Obviously, the related art still has room for improvement and requires breakthroughs.

Therefore, how to solve the problem is worthy of consideration by related manufacturers and those having ordinary skill in the art.

SUMMARY

In view of the drawbacks of the related art, it is a primary objective of the present disclosure to provide a pad structure that uses a first slider or a second slider or the first slider and the second slider having a primary junction and a secondary junction respectively, or having a lower wall block, a guide bump and a wall block to overcome the drawbacks of the related art.

A secondary objective of this disclosure is to provide a pad structure that uses a first slider and a second slider to provide a string suspension or form a guide angle by the primary junction and the secondary junction, so that inclined planes can be used to move and dislocate relative to each other and to shift the string from the center to correct the specific amplitude.

A further objective of this disclosure is to provide a pad structure that can effectively improve the convenience of adjustment and use and filter out specific amplitude of the racket frame and string and enhance or comply with the specific pound of force.

The problem of the related art to be solved by this disclosure is the vibration and shock of the commonly used racket frame with a string. Although related manufacturers have developed devices to reduce the vibration and shock of the anti-vibration force generated by striking the racket surface composed of the ball and the string can be absorbed and buffered and transmitted to the athlete's wrist and arm completely to allow the racket to be held stably, and adjust the weight around the racket frame according to the athlete's needs, yet the specific amplitude of the string is fixed, and cannot be fine-tuned to filter out specific amplitudes of the racket frame and the string, and cannot enhance and comply with a specific pound of force. The related art still has room for improvements.
