DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a golf practice device, and more particularly to a golf practice device that automatically sets a ball on a tee.

[Prior Art] Conventionally, when setting a ball on a tee during golf practice, it has been a common method for each practitioner to manually take out the ball from a basket or the like and place it on the tee.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional method, time and effort are wasted in setting the ball, and the practitioner must set the ball on the tee each time he/she hits the ball, which forces the practitioner to change his/her batting posture each time. , I had to change my stance, which was very inconvenient for effective practice.

At some large-scale golf driving ranges, ball feeding has been automated, but the equipment is generally large-scale, and it is difficult to say that it is widely used, much less for personal or home use. It has not been.

The present invention was created in view of these problems, and
It automatically sets the ball on the tee, allowing practitioners to continue practicing effectively without changing their batting posture and wasting time and effort, and is compact and can be used for personal and home use. The purpose is to provide a golf practice device.

[Means for Solving the Problems] Means for solving the above problems in the present invention include a tee on which balls are placed, a storage tank for accumulating a plurality of balls, and a vertical stand for receiving balls from the storage tank. A golf practice device consisting of a transfer arm that rotates between a posture and a lying posture that transfers the ball onto a tee, a support that rotatably supports the tee, and energization by the rotational movement of the support when the ball is hit. a first switch that is energized when the transfer arm is in the upright position; a third switch that is energized when the transfer arm is in the recumbent position; This golf practice device is characterized by comprising a motor that drives the transfer arm in both directions by rotating the transfer arm in one direction and in the other direction when the third switch is energized.

[Operation] In the present invention, the ball is transferred from the reservoir to the tee by tilting the transfer arm, and the transfer arm and the support of the tee are made rotatable and energized in accordance with their rotational position. Three contact switches are installed, and the transfer arm is driven by a motor that rotates forward and reverse depending on the combination of energized states. When the tee falls during a ball-hitting operation, the transfer arm tilts from an upright position to a recumbent position and automatically transfers the ball. It is designed to be placed on a tee.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In the figure, 1 is the ball, 2 is the tee, 3 is the reservoir, 4 is the transfer arm, 5 is the mat, and 6 is the ground.

A ball 1 is placed on a tee 2 and is hit. The storage tank 3 can store a plurality of balls, and the ball 1
is transferred from the reservoir 3 onto the tee 2 by a transfer arm 4. The transfer arm 4 is rotatable between an upright position and a recumbent position, receives the ball 1 from the storage tank 3 in the upright position, and
By leaning into a lying position, the ball 1 is placed on the tee 2.
Transfer to the top. In FIG. 1, the solid line indicates the transfer arm 4.
The dotted line indicates the upright position, and the dotted line indicates the lying position.

FIG. 2 shows the transfer arm 4 in a lying position.

The tee 2 and its mechanism are buried in the ground 6 through the mat 5, but may also be buried directly in the ground 6.

The transfer arm 4 has a rectangular cross section and is fixed to a rotatable square shaft 7, and a ball receiving member 8 is fixed to the square shaft 7 following the transfer arm 4. A long hole 9 is formed in the center of the ball receiving member 8, and a ball stopper 10 is disposed on the floor of the reservoir 3 facing the long hole 9. Ball stopper 10
is equipped with a hit pawl 11 and a spring 12, and is biased clockwise in the figure by the spring 12, and stops when the hit pawl 11 comes into contact with the floor surface, as shown by the dotted line in FIG. It has become. When the transfer arm 4 shifts from the lying position to the upright position, the ball receiving member 8 interlocked with the transfer arm 4 engages with the ball stop through its elongated hole 9 and presses the ball stop 10 in the counterclockwise direction. and press it to the floor. The ball stopper 10 becomes horizontal, and the ball 1 moves to the position shown by the solid line in the figure. When the transfer arm assumes a lying position, the ball receiving member 8 releases the force applied to the ball stopper 10, and the spring 12 returns to the position shown by the dotted line in the figure to stop the next ball.

A gear 13 is attached to one end of the square shaft 7, and is driven by a motor 15 via a gear mechanism 14 inside the box.

FIG. 3 is an explanatory diagram showing details of the square shaft mechanism of the present invention.

A push plate 16 fixed parallel to the transfer arm 4 and the ball receiving member 8 and a push plate 17 fixed perpendicularly to the push plate 16 are attached to the square shaft 7 at the position shown in FIG. A vertically adjustable pin 18 or 19 is provided through each plate surface. The pin 18 or 19 presses the cam member 20 from either side as the square shaft 7 rotates, and when the transfer arm 4 is in the vertical position shown in FIG. 2
When the transfer arm 4 is in the recumbent position shown in FIG. 3(b), the third switch 22 of the present invention is energized.

A shaft pin 33 is provided through the outer wall of the bearing case 29, and as shown in FIG. 5, a fan-shaped plate 34 is supported at one end by the shaft pin 33. At a position corresponding to the fan-shaped plate 34, the support shaft 28 has a cam body 35 having a circular cross section cut out.
is fixed thereto, and as the support shaft 28 rotates, the fan-shaped plate 34 is pushed up or lowered. Fan-shaped plate 34
rotates around the shaft pin 33, and when pushed up by the cam body 35, energizes the first switch 36 of the present invention.

As for the operation of this embodiment, as already mentioned, the ball 1
When the tee 2 is hit, the hit tee 2 rotates about 45 degrees, and the fan-shaped plate 34 energizes the electromagnet 37 and the first switch 36 .

On the other hand, the second switch 21 is pressed by the cam member 20 and turned on when the transfer arm 4 is in the vertical position, but current flows only after the first switch 36 is turned on, causing the motor 15 to rotate. However, the transfer arm 4 changes from the upright position to the lying position. When the tee 2 is hit, the electromagnet 30 is also turned off as the second switch 21 is turned off when the transfer arm 4 is in the lying position, and the coil spring 32 is turned off.
It is pulled back to its normal position by its elasticity. As a result, the ball 1 rolls on the transfer arm 4, falls from its tip, and is placed on the tee 2.

Due to the rotational movement of the square shaft 7, the push plate 17. Pin 19. The cam member 20 is pressed, the third switch 22 is energized, the motor 15 is reversely rotated, and the transfer arm 4 changes from the lying position to the upright position. At this time, a ball stopper 10 is inserted into the elongated hole 9 of the ball receiving member 8.
The tip of the ball is engaged and pulled down, and the next ball rides on the ball receiving member 8 and stops, waiting for the next ball to be hit.

In this way, all movements are performed automatically, and there is no need for the practitioner to change his or her batting posture.

[Effects of the Invention] As described above, according to the present invention, the ball can be automatically set on the tee, and the ball can be set on the tee without the practitioner changing his or her batting posture.
