Abstract

The present invention relates to a flexible golf tee, comprising: a supporting unit for supporting a golf ball; and a fixing unit coupled to the lower side of the supporting unit and fixedly inserted into the ground. The supporting unit is made of a different material with lower rigidity compared to the fixing unit. Thus, when a user hits a ball located on the supporting unit, it is possible to prevent a decline of the flying distance, the direction change, and the bouncing of the golf tee caused by the reaction force, which occur when the supporting unit receives the force.

Description

Flexible golf tee

The present invention relates to a golf tee, and more particularly, a support part supporting a golf ball and a fixing part inserted and fixed to the ground are formed of different materials, so that a part of the force striking the golf ball is offset by the reaction force of the golf tee. It relates to a flexible golf tee that can be minimized.

In general, a golf tee (GOLF-TEE) is a tool that puts the ball on when you take the first shot, the TEE SHOT, from the starting area of each hole during a golf game.It is like a nail made of wood or plastic, and is used for wood putters. There are long ones (long tea or long long tea depending on the length) and short ones for irons (short tea). Until the 1920s, golfers used wet sand or mud to make tee shapes and then tee shots to damage the head of a golf club. However, since the creation of the golf tee, although the size is small, it has a function that cannot be ignored enough to determine the distance and pitch of the golf ball depending on the height and slope of the golf tee and the degree of resistance to the golf ball. It is sold on the market with the addition of advanced technologies.

These golf tees have to be inserted and fixed to the ground, so they are made of a material having a certain degree of rigidity.However, when a user strikes a golf ball with a golf club, some force is transmitted to the golf tee, and this force acts as a reaction force. Therefore, the reaction force generated from the golf tee affected the user's flying distance and the direction of movement of the golf ball, and in the case of the golf tee, there was a problem that the golf tee was frequently lost because it bounced from the installed position by the reaction force. .

Accordingly, there is a need for a new golf tee capable of solving the above-described problems.
