DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tee height adjusting mechanism for a golf practice machine which is installed under the floor of a golf driving range or the like and in which a golf ball is automatically supplied and teeed up. It is.

[0002]

2. Description of the Related Art A golf practice machine in which a golf ball is automatically supplied onto a tee has already been proposed. In these training machines, the tee is provided so as to be able to move up and down, and is immersed under the floor when descending.
The tee is supplied, and the ball is supported on the upper end surface of the tee. Then, the tee is raised while holding the ball, and the upper end of the tee is projected from the floor surface. -Up and down operation of the tee is held by the vertical guide so that the tee does not fall down,
The tee is attached to the tip of the arm and the arm is tilted. The height at the time of teeing up can be adjusted by moving the fulcrum of the arm.

[0003]

In the conventional tee lifting and lowering device, the tee is raised, that is, the position where the tee projects from the floor surface while holding the golf ball, that is, the so-called tee.
Adjustment of the height at the time of raising is performed by changing the position of the fulcrum of the tilting arm and adjusting the elevating distance at the tip of the arm, but the mechanism is complicated and causes trouble. The present invention is an improvement of such a point,
A golf ball that can change the tee up / down distance by limiting the range of tilt of the arm, enables height adjustment during teeing up, and can be freely adjusted to the desired height of the golf practitioner. To provide an automatic supply device.

[0004]

SUMMARY OF THE INVENTION A golf training machine tee height adjusting mechanism according to the present invention includes a tee provided to be able to move up and down, an arm having the tee attached to a tip thereof, and a It consists of a fulcrum that rotatably supports the other end,
The tilting range of the arm is limited by the rotation of the cam plate, and the height of the tee attached to the elevating unit can be freely adjusted. The tee is raised by the arm being tilted about the fulcrum by a spring or a motor.

[0005]

In the golf training machine tee height adjusting mechanism of the present invention, the arm tilts around the fulcrum, and the tee attached to the tip of the arm controls the tilting of the arm by the cam plate. By arbitrarily restricting the height, the height can be freely adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the golf ball automatic supply device of the present invention will be described with reference to the drawings. E is a tee made of a flexible material such as plastic or rubber, and the golf ball A is placed and held on the upper end surface thereof. The elevating unit D to which the tee E is attached is attached to the tip of the arm C,
The golf ball A is supplied at the lower limit point F of the tee E, and when the tee E rises, the golf ball A moves upward while being held by the tee E. When the elevating part D reaches the upper limit point G, the upper part of the tee E projects from the floor surface, and the golf ball is
It will be up. C is an arm, the tip of which is pivotally supported by a lifting section D. At the rear end of the arm C, a fulcrum pin B
The arm C can be tilted with the pin B as a fulcrum, and the tee E pivotally supported by the tip of the arm C moves up and down with this tilt. Body and arc
A spring K is attached to the vicinity of the rear end of the arm C, and the tip of the arm C is urged to rise.
Further, an eccentric cam plate is attached to the main body.
The interval can be adjusted steplessly.

Next, the operation of the mechanism will be described.
FIG. 1 shows a state in which the arm C is at the lower limit point F and the upper limit point G. When the arm C is at the lower limit point F, the tee E is sunk downward from the floor surface. Tea E in this state
Is supplied to the upper end surface of the tee E, and the ball A is held on the upper end surface of the tee E. Next, when the vertical drive cam plate L provided in the middle of the arm is rotated, the arm C is tilted upward about the pin B by the spring K, and the tee E is raised. At this time, the upper portion of the tee E projects from the floor surface, and the golf ball A is held on the tee E, which is a so-called tee-up state.
The vertical drive cam plate L and the spring K keep the arm constant.
It is a tilting means for tilting to a range. Next, when the golf ball is hit and released from the tee E, the sensor detects this and the vertical driving cam plate L rotates, and the arm C
Returns to the lower limit point F, and the next golf ball is supplied on the tee E. The adjustment of the upper end position of the tee E, that is, the height adjustment of the tee, is performed by rotating the eccentric cam plate I attached to the main body. By rotating the eccentric cam plate I to the position shown in FIG. 2, the height of the tee E is set to the upper limit point G, and by rotating the eccentric cam plate I to the position shown in FIG. The distance between the intermediate point H and the upper limit point G can be arbitrarily adjusted by the rotation of the eccentric cam plate.

[0008]

In the golf training machine tee height adjusting mechanism of the present invention, the height of the arm, that is, the height of the tee-up, can be adjusted steplessly by the eccentric cam plate, and the golf tee can be adjusted. The trainee can adjust the height of the tee up according to his / her preference, and when performing the lifting / lowering operation with the spring, it is performed using only the cam plate and the spring. In addition, the manufacturing cost can be reduced.
