Description

Golf exerciser {GOLF TRAINER FOR PUTTING AND CHIP SHOT}

The present invention relates to a golf exerciser, and more particularly, to a golf exerciser that is capable of practicing chip shots as well as putting practice corresponding to various distances as in the green of a real field even in a narrow space.

Golf putting exerciser that solves the disadvantage that the conventional golf putting exerciser was limited to only a limited distance putting practice of about 2m has been disclosed as the Korean Utility Model Registration No. 152039 by the applicant of the present applicant.

The conventional golf putting exerciser disclosed herein is, as shown in Figure 1, the golf putter exerciser having a ball start portion 22 and the target that the ball collides with the ball and the green mat 20 is guided the ball The case bottom plate 39 and the ball inlet hole having a putting hole portion 30 and a guide groove 38 formed of a stepped upper surface and left and right partition walls 34a and 34b and a known target sensing plate 36 are provided. The purpose of the Utility Model Registration Claim is to consist of a case cover 40 having a 42), a known digital distance indicator 44 and a ball outlet 46, and an inclined plate 50 having a support piece.

The conventional golf putting exerciser configured as described above is equipped with a target detection plate 36 in the putting hole portion 30 to detect the hitting strength and the degree of follow-through of the putting hit detection sensor of the detection plate 36 to detect the impact impact of the ball Detect and convert the impact strength into the distance to the digital distance indicator (44) is configured to represent the putting distance numerically, and adjust the distance freely from about 2m to 5m, 10m, 20m, 30m, the distance of the actual putter Allow you to practice putting.

The conventional putting exerciser described above displays the putting distance by converting the distance by the impact strength caused by the collision with the ball, but most impact sensors display the voltage conversion characteristic of the impact because it has a non-linear characteristic curve. Since there is a problem that the reliability of the putting distance is poor, there is a need for a putting exerciser that can derive the putting distance more accurately.

In addition, in the case of using a conventional putting exerciser, the head-up is often performed by the player's eye movement at the last moment of the follow-through. In other words, the player takes an action to unknowingly see the digital display mounted on the front of the case with the ball slot to immediately check his putting distance. Therefore, there is a need for a method to fundamentally exclude the head-up when practicing golf putting through the exerciser.

On the other hand, if the ball on the field is not settled on the green where the hole cup is located and falls outside the green not far from the hole cup, the ball is dropped a certain distance and the ball falling on the green rolls toward the hole cup by the inertia. Will be

In this chip shot, the parabolic angle drawn by the ball in the air and the rotation of the ball act as important variables, so the player must have a certain sense of his own.

Although chip shots are a very important part in reducing the number of hits in the golf game, there was no golf exerciser that can practice chip shots in a narrow space in the past. Therefore, the necessity of a golf exerciser that can practice both putting and chip shots Will be enough.

The present invention has been devised to solve the above-mentioned conventional problems and to meet the demands. The present invention provides a more accurate display of the putting distance and fundamentally solves the head-up during putting to make the putting posture as needed. Aims to provide a golf exerciser that allows the free practice of chip shots.

According to the present invention for achieving the above object, it has a ball start portion which is the position from which the ball is launched, and has a green mat, a ball inlet and a ball outlet having a normal length and width, and a recovery path of the ball introduced into the ball inlet. The main body having an inside, an optical sensor installed inside the ball inlet of the main body and detects the ball passing through the ball inlet, and calculates the speed of the ball detected by the light sensor, the actual green for each ball speed Algorithm processing unit for storing the algorithm data about the putting distance of the ball to which the rolling resistance is applied and derives the putting distance of the ball in the pre-stored actual green condition according to the detected speed of the ball, and outputs from the algorithm processing unit Providing a golf exerciser, characterized in that it comprises a digital distance indicator for displaying the data in numerical value in units of distance do.
