Description

Description: TECHNICAL FIELD The present invention relates to a method of adjusting the height of a tee supporting a golf ball from below to a height and a posture of a golfer when practicing golf at a golf driving range. The present invention relates to a golf tee height adjustment device that allows a golfer to easily adjust and control the height of the golf tee without mechanically selecting and using several different tees by a mechanical device based on forward and reverse rotation of a motor. .

BACKGROUND ART When practicing a swing or the like at a golf driving range, a golfer can freely adjust the height of a tee that supports a golf ball from below according to the posture and height of the golfer, thereby enabling a more effective swing.

However, in the past, when trying to adjust the tee height at a driving range, the golfer himself had to use several tees of different standards with different heights each time. Not only was there an annoyance, but some golf driving ranges now have a device that only adjusts the height of the tee. However, this known device does not have an interlocking mechanism as in the present invention, and has an exercise area. However, there is a drawback that the ground area required for installation is large due to the adoption of a wide cam or crank mechanism, and the installation work is not easy. There is also a disadvantage that a gap is formed between the tee and the arm of the golf ball feeder, and the tee-up of the ball tends to be unstable.

DISCLOSURE OF THE INVENTION The present invention adjusts the height of a golf tee when practicing golf at a golf driving range. The height adjustment of the golf tee allows the height of the tee to be adjusted up and down arbitrarily while keeping the distance between the two automatically linked up and down at the same time as the mounting table for the automatic ball feeder It is intended to provide a device.

The gist of the technology is a forward / reverse motor speed reducer that can rotate forward and backward by connecting the upper and lower support bases vertically with a vertical guide rod, providing a screw rod at the center thereof, and projecting the upper end to the upper support base. And a bevel gear are engaged with each other, and a vertically movable platform is inserted into the vertically movable guide rod, and a nut connected to the center thereof is screwed into a screw rod. The golf ball feeder and the golf ball tee simultaneously move up and down while simultaneously moving up and down so as to adjust the height of the golf tee while always maintaining the same distance from each other.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall perspective view in which a part of the present invention is cut and displayed. FIG. 2 is a sectional explanatory view showing an operation of the present invention. FIG. 3 is a side explanatory view showing an operation of the present invention. 1, 1 ': vertical support, 2, 2': lifting guide bar, 3: screw bar, upper end of 3 'screw bar, 4: forward / reverse motor, 4': forward / reverse motor 5, 5 ': bevel gear, 6: elevating platform, 7; moving nut body, 8, 8': vertical limit switch, 9: mounting table, 10: tee Examples will be described in detail.

The upper and lower support bases 1 and 1 'are connected to each other by lifting guide rods 2 and 2' on both sides, and a screw rod 3 is provided at the center thereof so that the upper end 3 'protrudes above the upper support base 1; A forward / reverse motor 4 capable of forward / reverse rotation is installed on one side of the upper support 1, and the rotation shaft of its speed reducer 4 'is meshed with the upper end 3' of the screw rod 3 by the bevel gears 5, 5 '. An elevating platform 6 is provided on the elevating guide bars 2, 2 'so as to be able to move up and down, and a moving nut body 7 is fixedly connected to the center of the elevating platform 6, and this is screwed to the screw bar 3, so that 3 to be able to move up and down.

The upper and lower limit switches 8 and 8 'are provided on the side of the traveling path, and the mounting table 9 for a golf ball feeder and the tee for a golf ball are provided below the limit switches.

The reference numeral 11 denotes a case, 12 denotes a switch, 13 denotes a golf ball, and 14 denotes an automatic golf ball feeder.

The operation of the present invention configured as described above will be described as follows.

First, when the device of the present invention is used in a golf driving range, after providing a recess at the height of the tee 10 on the floor of the driving range and fixing and installing the device of the present invention on one side surface of the recess, If the known golf ball automatic feeder 14 is mounted on the mounting table 9, the installation is easily completed.

In the present invention, if the golf ball automatic supply machine 14 is operated after the installation as described above, the golf ball automatic supply machine 14 automatically supplies the golf ball 13 to the upper portion of the tee 10, and the golfer continuously supplies the golf ball. Because he can hit, golf practice can be easily performed.

At this time, if it is necessary to adjust the height of the tee 10 depending on the height and swing posture of the golfer, the forward / reverse motor 4 can be adjusted by selecting the switch 12 connected to the outside up-down. When the screw rod 3 is rotated in the normal or reverse direction by the reverse rotation, the moving nut body 7 of the lifting table 6 screwed to the screw rod 3 moves up and down, and the mounting table 9 and the tee 10 provided at the lower end thereof are moved. At the same time, it can be moved up and down, so that the height of the position can be adjusted arbitrarily.

 This will be described in more detail with reference to examples.

When the position of the tee 10 is to be raised, if the upward switch of the switch 12 is pressed, the forward / reverse motor 4 rotates in one direction and the screw rod 3 meshed with the bevel gears 5, 5 'rotates. As a result, the moving nut body 7 of the lifting platform 6, which moves while being loosely engaged with the lifting guide bars 2, 2 ', rises, and the positions of the mounting table 9 and the tee 10 provided at the lower end thereof also rise. If the hand is released from the switch 12 at a certain height, the rotation of the forward / reverse motor 4 is stopped.
Also stop. In this case, the lift 6 reaches the position of the upper limit switch 8 already set even if it is pressed by hand continuously, and if it touches the limit switch 8, it does not rise to any higher height. Even when the operation of the switch 12 is inexperienced, the movement is only within the set range, and the height of the tee 10 can be easily controlled.

When the height of the tee 10 is to be lowered, the forward / reverse motor 4 is rotated in the opposite direction while the reverse rotation of the forward / reverse motor 4 is performed by pressing the down switch of the switch 12 in the opposite direction. The platform 6 descends. Also in this case, it is lowered only within the range set by the lower limit switch 8 '.

Therefore, since the height of the tee 10 can be easily adjusted only by operating the switch 12, it is not necessary to replace several tees of different standards in order to adjust the height of the tee 10 as before. Therefore, it is very convenient and easy to use.

Further, since the tee 10 and the mounting table 9 are raised and lowered at the same time, the interval is always kept constant.

INDUSTRIAL APPLICABILITY As described above, the present invention is intended to adjust the height of the tee supported from the lower part of the normal position of the golf ball to an arbitrary height in accordance with the golfer's posture when practicing golf. Thus, the motor can be operated up and down mechanically by the forward and reverse rotation of the motor, and the height adjustment can be easily controlled, so that the efficiency of golf practice by golfers can be greatly enhanced.
