Description

BACKGROUND

The present invention relates to an automatic shuttlecock collecting and supply apparatus and, more particularly, to an automatic shuttlecock collecting and supplying apparatus that can automatically launch shuttlecocks for badminton so that users can practice alone, and allows users to practice badminton alone to practice theirs forms, steps, hitting points, and time using shuttlecocks thrown in various directions.
In general, badminton is a game that anyone can easily enjoy regardless of sex and age outside and in small indoor places with a racket and a shuttlecock by striking a shuttlecock to the counterpart without letting the shuttlecock strike the ground.
Badminton is, similar to tennis, played with two sides in which a side strikes a shuttlecock with a racket to the other side over a net at the center between them and points are scored by striking the shuttlecock and landing it to the floor within the opposing side. The forms of the game are “male and female singles” (one player per side) and “male, female, and mixed doubles (two players per side), and amateurs play the game in each class based on age and ability, so anybody can play the game regardless of sex and age.
However, beginners learn the techniques of badminton from experts usually in a way an expert passes over shuttlecocks one by one with a racket and a beginner receives the shuttlecocks, so it is possible to practice in various ways, but the way of striking shuttlecocks that randomly come is not substantially helpful for expert and beginners.
Further, beginners of badminton practice various techniques of badminton by correcting their forms through a coach or textbooks and beginners who do not have a level counterpart cannot help individually practicing alone such as swing and step with a racket.
Further, in badminton, the differences in level of beginners, intermediates, and experts are large, so beginners have to practice alone for a sufficient time until their abilities rise to higher level enough to play with intermediates and experts, but they practice alone for a too long period of time, they lose their interests in badminton and easily give up.
