Abstract

PURPOSE:To enable bringing a tee-shooting closer to the actual touch thereof by providing a cylinder body in a hole formed on the surface of the ground vertically movablly projecting a tee member through a through hole provided at the upper end of the cylinder body with a projection value thereof adjustable. CONSTITUTION:By the rotation of a drive disc 8, a pin member 9 is lifted up to the highest position from the lowest end with a tee-up mechanism 7, and as a lift base 10 having the bottom surface thereof retained on the member rises, a cylinder body 11 rises sliding over an internal surface of a guide tube 1. In addition, a tee 12 positioned in the cylinder body 11 also has a bottom plate thereof adjusted and fixed with a support rod 17 and hence, it is set at a protruded part upward from the ground surface GL. A hole formed on a mat surface is closed with the upper surface of the cylinder body 11 at the same level as that of the ground surface and the height of the tee 12 reaches an actual tee-up height. Moreover, the diameter and the height of the tee 12 are adjustable optionally and a ball set is stable. This allows a training person to do a training with the same touch as that in the actual course.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a device for automatically teeing up a golf ball on a driving range.

[0002]

2. Description of the Related Art Conventionally, a lot of mechanisms for stably performing tee-up of a ball in this practice machine have been proposed, for example, Japanese Utility Model Publication No. 33-1026.
JP-B 35-21943, JP-B 37-4400
Publication, Japanese Utility Model Publication No. 44-22976, Japanese Utility Model Publication No. 49-1
1872 and JP-A-54-97122,
It has a mechanism to pick up the ball from the shoot to the arm,
There is disclosed a structure in which the picked-up ball is mounted on a rubber tee from a vertically rotating arm through a drop hole provided at the tip.

Among them, a machine for automatically teeing up a golf ball on a golf driving range places the ball conveyed from a ball supply facility under the ground of a batting mat on a tee-up tee rubber and allows the ball to pass through. The mat is lifted to the surface of the ground through a hole formed in the mat with an allowance, and the height from the ground surface, that is, the mat surface is adjusted by adjusting a mounting base to which a rubber tee is mounted.

There is a large hole drilled in the mat at the base of the tea rubber protruding on the mat, and from a practitioner's point of view with the ball placed on the tea rubber, the hole drilled in the mat is Due to its existence, it looks higher than the actual ground surface.

If the hole formed in the rubber and the mat becomes large, balls falling from the rubber during practice may fall into this hole, so the diameter is 23 m.
It is made to have a size of about m, and has a small difference in diameter from the hole formed on the mat surface having a diameter of about 60 mm.

[0006]

Thus, in the conventional practice machine, when the ball is teeed up, the practitioner can see the hole on the mat, which gives the practitioner the illusion that the tea rubber is long. When hitting a ball, the mat hole may hit the club head, which may damage the player's wrist.

Further, increasing the diameter of the tee causes a great resistance to the tee when hitting the ball, which causes a large discomfort with the tee shot on the actual course, which makes it difficult to obtain the satisfaction of the practitioner.

[0008] The problem to be solved by the present invention is to solve the problem of the tee-up part of the conventional practice machine, and to practice the tee shot in the practice field. It is intended to provide a device for bringing the sensation closer.

[0009]

SUMMARY OF THE INVENTION The present invention has a supply pipe for supplying a ball for hitting balls under the ground surface for setting a practice ball, and from the supply pipe, the balls fall by rotation one by one on a tee capable of ascending and descending. In a golf practice machine with a tee-up mechanism that sets the ball on the same tee and raises the tee with the ball set from the hole provided on the ground surface, the tee-up mechanism is set inside the hole formed on the ground surface. A cylindrical body is provided so as to be movable up and down, and a tee member is projected through a through hole provided in an upper end surface of the cylindrical body so that a protruding amount can be adjusted.

[0010]

The upper end surface of the vertically movable cylinder completely closes the hole provided on the mat surface except for the protruding portion of the tee member, and the same fiber material as the mat surface is formed on the upper surface of the cylinder body. By arranging, the hole for raising and lowering does not give an illusion to the height of the tee at the base of the tee protruding from the ground surface,
Also, the diameter of the tee can be adjusted arbitrarily.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view showing the entire structure of a training machine of the present invention, showing a state in which a tee-up portion is located at the lowest position.

In the figure, reference numeral 1 denotes a guide tube fixed to a hole 4 formed in a base material 3 of a mat 2 provided on the ground surface and having an inner diameter larger than that of a golf ball. A golf ball introduction port 20 for introducing a golf ball G transferred from a transfer pipe 5 disposed in the ground is provided on one side surface below the guide tube 1. Reference numeral 6 denotes a feed mechanism for intermittently feeding the ball G from the transfer pipe 5 to the introduction port 20 of the guide pipe 1. Reference numeral 7 denotes a tee-up mechanism for teeing up the golf balls G supplied one by one from the introduction port 20. The tee-up mechanism 7 is a lift table 10 that lifts and lowers a pin member 9 fixed to the periphery of a drive disk 8.
By contacting the lower end surface of the same, the drive disk 8 connected to a motor (not shown) is rotated to move the lift base 1
It is a mechanism to raise and lower 0. A cylindrical body 11 is fixed to the lift table 10 by penetrating the lift table 10. A hole 13 is formed in the upper end surface of the cylindrical body 11 for the tee 12 to pass through, and fibers 14 made of the same material as the ground surface mat 2 are attached to the other portions. The above-mentioned tee 12 is made to have substantially the same diameter as a normal wooden tee and its upper end is also made to have the same shape as a normal ball receiver, but it can be made to have any shape as required. A bottom plate 15 having a diameter slightly smaller than the inner diameter of the tee mounting cylinder 11 is formed on the lower end surface of the tee 12.
A spring member 16 is arranged between the upper surface of the above and the lower surface of the upper end surface of the cylindrical body 11. 17 is a bottom plate 15 of the tee 12.
Shows a support rod that supports the lower surface of the device and whose vertical position can be changed by an electrical instruction from the outside (not shown). This support rod 17 is rotated by an external drive,
By engaging and moving the screw mechanism 18 formed on the outer surface of the rod 17, the amount of protrusion of the tee 12 from the tubular body 11, that is, the height of the tee 12 can be adjusted. 19
Indicates a stopper for stopping the rising by hitting the lower end of the guide tube 1 when the cylinder 11 is rising.

When the training machine having such a structure is started, the ball G in the transfer tube 5 is rolled by the rotation of the intermittent feed mechanism 6 by an external operation, and the introduction port 20 on the side surface of the guide tube 1 is rotated. Tumble down from the tee 12
Placed on the upper surface of.

FIG. 2 shows a state in which the golf ball G placed on the tee 12 is projected from the position of the ground surface GL and set at a predetermined tee height.

The rotation of the drive disk 8 causes the tee-up mechanism 7 to lift the pin member 9 from the lowermost position shown in FIG.
0 rises. Along with this, the cylindrical body 11 moves up while sliding on the inner surface of the guide tube 1.

Further, the tee 12 located inside the tubular body 11 is also fixed to the bottom plate by adjusting the bottom plate by the supporting rods 17, so that the tee 12 is set at a position projecting upward from the ground surface GL.

In the set state of the ball G, the hole formed in the mat surface is closed by the upper surface of the cylindrical body 11 at the same level as the ground surface, and the height of the tee 12 is the actual height of the tee-up. It will show itself. Moreover, the diameter and height of the tee 12 can be arbitrarily adjusted,
The set ball is stable, allowing the practitioner to practice with the same feeling as on the course.

[0018]

According to the present invention, the following effects can be obtained.

(1) Even if the ball falls from the tee, it does not fall into the mat hole, and the ball can be practiced smoothly.

(2) The mat hole can be made to have a minimum diameter through which the ball can pass, and the club head is driven less frequently, so that the mat is consumed less.

(3) At the time of hitting the ball, the hole formed in the mat is closed, and since the tee can be any thin one, there is no feeling of resistance when hitting the ball.

(4) Since the mat hole is closed, it does not get caught on the mat even in the practice of hitting with an iron.
