Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a tee-up arm for a golf practice device for automatically setting a golf ball on a tee.

[Conventional technology]

With the recent popularity of golf, many golf practice ranges have been built, and in these practice ranges, a golf practice device for automatically setting a golf ball on a tee is widely used.

The tee-up mechanism of the golf ball in the golf practice device is composed of a tee-up arm that turns toward a tee mounted on a mat base and a ball supply mechanism that feeds the balls in the ball storage box to the tee-up arm one by one. When the player hits the ball,
The tee-up arm is designed to return to the ball supply mechanism side and not interfere with the ball hitting.

However, it is not uncommon for the player to swing the club and accidentally hit the tee-up arm before the tee-up arm has completely returned to its standby position. When an excessive force is applied to the tee-up arm from the outside, not only the arm but also its drive mechanism and ball supply mechanism are often damaged.

Therefore, for example, in the golf ball automatic tee-up device disclosed by the applicant in Japanese Patent Application No. 62-316100, when the player hits the ball by swinging the club forward, the club touches the tee-up arm. In this configuration, the tee-up arm is bent and its tip moves forward, so that the drive mechanism of the tee-up arm and the ball supply mechanism are not impacted.

However, after the player hits the ball, when the tee-up arm comes out to set the next ball, the club that hit the previous ball returns and hits the arm, or before the player hits the ball. , When moving the club head back and forth near the ball to align the club, it may bump into the arm while it is returning.In such a case, the tee-up arm may receive backward force. Could damage the device.

[Problems to be solved by the device]

The present invention has been made to solve the above problems, and its purpose is to provide a drive mechanism for a tee-up arm and a ball supply mechanism regardless of whether the club hits the tee-up arm from the front or back. It is intended to provide a tee-up arm for a golf practice device in which a portion is not impacted.

[Means for Solving the Problems]

The purpose of the above is to divide the arm into a tip part and a base part, and configure the connecting part of the two parts as a fitting joint that allows the tip part to easily fall off from the base part when an external force exceeding a predetermined value is applied to the tip part. At the same time, it can be achieved by a tee-up arm characterized in that both are gently anchored by an elongated flexible member.

As the elongated flexible member, a long coil spring, a cord, a long rubber or the like is suitable.

[Action]

With the above-mentioned configuration, even if the club hits the tee-up arm from either the front or back direction, the tip part and the base part of the arm are disengaged at their joints, which makes it impossible for the arm drive mechanism and the ball supply mechanism in the device body. Since no force is applied, no trouble occurs, and the detached tip part is anchored to the base part by an elongated elastic member such as a coil spring, so it does not fly far and the player can practice with confidence. It is a thing.
