Abstract

PURPOSE:To prevent an ascent failure of a tee by allowing the tee to ascend by a spring attached to an arm, in the automatic golf ball supply device for allowing the tee to ascend and descend by tilting of the arm. CONSTITUTION:An ascending/descending part C to which a tee D is attached is supported by a guide shaft L and can move vertically in a guide box M, and a golf ball is supplied in a descent position of the tee D, and when the tee D ascends, the golf ball ascends and moves in a state held by the tee D. The tip of an arm H is supported axially by the ascending/descending part C, and to the rear end of the arm H, a supporting point G is fitted and coupled, and the tee D is moved vertically in connection with tilting of the arm H. A spring J is attached between the main body and the vicinity of the rear end of the arm H and energized so that the tip of the arm H ascends, the arm H is allowed to descend by a rotation of a cam plate, and the part between a height middle position E of the tee and the upper limit position F is adjusted steplessly.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf ball automatic supply device which is installed under the floor of a golf driving range or the like and is automatically supplied with a golf ball for teeing up.

[0002]

2. Description of the Related Art A golf training machine in which a golf ball is automatically supplied onto a tee has already been proposed. These practice planes are provided with a tee that can be moved up and down so that they can be immersed under the floor when descending, and under the floor, the golf ball is placed above the tee.
Is supplied to support the ball at the upper end surface of the tee, and then the tee is raised by the rotation of the motor while holding the ball, and the upper end of the tee is projected from the floor surface. Let's tee up, and tee up again
The vertical movement of the tee is carried out by holding the side surface of the tee with a vertical guide so that the tee does not fall down, attaching the tee to the tip of the arm, and tilting the arm. .

[0003]

In the conventional automatic golf ball feeder, the arm is raised by the rotation of the motor. However, troubles such as failure of the motor due to poor tee rise due to clogging of the golf ball or the like occur. Was there. The invention of the present application solves such a point, and an object of the present invention is to provide an automatic golf ball feeder by raising a tee by a spring material.
It is also possible to adjust the height at the time of tee-up by making it possible to change the ascending / descending distance of the tee by using the cam. Therefore, it is possible to provide a tee height adjusting mechanism in a golf training machine which can be freely adjusted to a height desired by a golf trainer.

[0004]

The golf ball automatic feeder according to the present invention raises the arm by the elasticity of the spring material, and the arm always tries to be lifted upward by a spring or the like. Then, a tee that can be raised and lowered, an arm that attaches the tee to the tip, a pin that rotatably supports the other end of the arm, a spring that is attached to the arm, and an arm. The cam is in contact with the cam plate, and the spring causes the arm to tilt upward around the pin to raise the tee, and the rotation of the cam plate tilts the arm downward to raise and lower the tee attached to the lifting unit. Let

[0005]

The automatic golf ball feeder of the present invention is
The arm tilts about the pin as a fulcrum, and the tee attached to the tip of the arm tilts upward due to the force of the spring. Further, by providing a separate cam plate, it is possible to limit the tilting range of the arm by the rotation of the cam and to arbitrarily adjust the height of the tee-up.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the golf training machine tee height adjusting mechanism of the present invention will be described with reference to FIG. D is a tee made of a flexible material such as plastic or rubber, and the golf ball is placed and held on the upper end surface thereof. The elevating part C to which the tee D is attached is supported by the guide shaft L and can move up and down in the guide box M. The golf ball is supplied at the lowered position of the tee D, and when the tee rises, the golf ball
Le moves up while being held by Tee-D. When the elevating part C reaches the upper limit position F, the upper part of the tee protrudes from the floor surface, and the golf ball is teeed up. H is an arm, the tip of which is pivotally supported by the elevating part C. A fulcrum pin G is fitted and connected to the rear end of the arm H, and the arm H can be tilted about the pin G as a fulcrum. With this tilting, the arm H is attached to the tip of the arm H. The pivotally supported tee D moves up and down. A spring J is attached between the body and the vicinity of the rear end of the arm H, and the tip of the arm H is urged to rise. Further, a cam plate and an eccentric cam plate are attached to the main body. The rotation of the cam plate lowers the arm H, and the rotation of the eccentric cam moves the tee height from the intermediate position E to the upper limit position F. It can be adjusted steplessly.

Next, the operation of the device will be described.
The state shown by the broken line in FIG. 1 is when Tee-D is at the lowermost position, and Tee-D is immersed downward from the floor surface. In this state, the ball is supplied to the upper end surface of the tee D,
This ball is held by the upper end surface of the tee D. Next,
When the cam plate I is rotated, the arm H tilts upward with the pin G as a fulcrum by the spring force of the spring J, and reaches the upper limit position F when the tee D reaches the position indicated by the solid line in the figure.
At this time, the upper portion of the tee D is projected from the floor surface, and the ball is held on the tee D, which is a so-called tee-up state. Next, when the ball is hit and released from the top of the tee D, the sensor detects this and the cam plate I rotates, and the arm H returns to the original lowermost position and the tee D The next golf ball is supplied on top. The upper end position of the tee D is adjusted, that is, the height of the tee up is adjusted by rotating the eccentric cam K attached to the main body. As shown in FIG. 1, the height of the tee D can be arbitrarily adjusted steplessly from the intermediate position E to the upper limit position F by rotating the eccentric cam.

[0008]

In the automatic feeder of the invention of this application, the lifting operation is performed by using the cam plate and the spring, so that the structure is simple and the manufacturing cost can be reduced. In addition, the conventional tee lifting mechanism may be damaged in the event of a malfunction such as a ball clogging or a motor abnormality. However, in the mechanism of the invention of this application, the lifting force is not likely to be damaged by using the spring material.
