Disk Shaped Apparatus for Racquet Sports

Abstract

The invented apparatus is useful in any sport that uses a racquet, a bat, a club, a stick, or anything similar. It helps to improve user awareness of his/her wrist angle relative to the handle axis by providing the user with touch feeling and visual indication. Without electronic sensors or any attachment to the user's body, the invention provides real-time feedback for self-correction.

1 . The invented apparatus is useful in any sports that uses a racquet, a bat, a club, a stick, or anything with a handle to hold with the user's hand(s). The said apparatus provides the user with real-time feedback on his/her forearm angle relative to the handle axis. More specifically, when the angle between the forearm and the handle is smaller than the intended value, the invented disk shaped apparatus interferes with the forearm or wrist area, providing the user with touch feeling and visual evidence as well. The improved awareness of the wrist position before, during, and after playing makes the self-correction possible before, during, and after as well. 
     
     
         2 . Unlike a normal end portion of a sports equipment handle, the said apparatus comprises a disk shaped feature with a large profile that cannot be gripped over by a hand. The said profile can be a circular shape or any non-circular shape. It can be axial symmetrical or non-symmetrical as well. The said large profile feature is able to contact the user's forearm and/or wrist area to provide touching pressure when the angle between the forearm and the handle gets smaller than a preset value. 
     
     
         3 . The said apparatus can be made from rigid material or elastic material. The said apparatus can be made as part of the original equipment or as an attachment to the original equipment. The attachment can be permanent or removable. The said apparatus can be comprised with multiple components as well as a single-part apparatus.
