Title:
STRUCTURE OF TENNIS PRACTICE FRAME
Document Type and Number:
WIPO Patent Application WO/2022/039443
Kind Code:
A1
Abstract:
The present invention relates to a giyeok-shaped tennis practice frame provided to be much taller than the height of a person from the ground or a wall-attachable tennis practice frame provided on a bracket (101) provided at a certain point of a house or a building, which is much higher than the height of the person. In the formation of the tennis practice frame, the characteristics of connection strings (200, 210) that suspend a ball are most important apart from a basic frame. A technique for a tennis practice frame, in which deep concerns about the characteristics of ball connection strings pervade, has not been disclosed yet. In addition, for ball connection strings to normally function, a weight may be mostly mandatory for the ball connection strings. The tennis practice frame according to the present invention is a practice frame with which a trainee performs tennis practice while repetitively hitting a ball falling in front of the trainee along a circumferential curve by means of gravity after flying along a circumferential orbit around a weight (300) at the end of a horizontal pole as the center thereof, that is, toward the sky in front of the trainee, when the trainee hits the ball with a racket.
