Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a golf practice machine for practicing putting shots.

The putting green of a golf course has various slopes, and when making a putting shot, it is necessary to hit the ball depending on the slope.

Conventionally, in order to adapt to such an inclination, a training device is known in which the road surface on which the shot ball rolls is inclined.

By the way, on actual putting greens, the shot position, that is, the ground that serves as a foothold for the player, is often sloped, and the player's posture tends to become unstable.

On the other hand, with conventional devices that simply slope the surface of the ball's path, the ground at the shot position is flat and the shot position is stable at all times.
The drawback was that it was not possible to practice effectively in line with the actual competition.

Furthermore, it has been proposed that a telescoping leg mechanism is provided at the corner of the movable plate to support the movable plate so that it can be tilted, thereby making the shot position freely tiltable. There was a problem in that the attachment point of the telescopic leg mechanism was geometrically displaced, making it impossible for the telescopic leg mechanism to extend and retract smoothly, and eventually becoming inoperable.

This invention was made in consideration of such circumstances, and includes a movable plate that can arbitrarily change the shot position and the angle of inclination from that point to the bottom, and allows for practicing how to shoot from different postures according to various angles of inclination. That is, the objective is to provide a golf practice machine that allows practice on the actual green and allows the angle to be adjusted reliably and easily.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a rectangular movable board 1 is provided as a putting green.

The surface of this movable plate 10 is made into a lawn surface with artificial grass or the like, and a plurality of holes 2 are arranged in a distributed manner from one end side to the other end side.

The movable plate 1 is installed at the same height as the bed 3 in a room, for example, and a shot position 4 is set at one end 1a of the movable plate 1.

A tilt 1 drive mechanism 5 is provided at the bottom of this movable plate 10,
The movable plate 1 is tilted at an arbitrary angle.

This tilt drive mechanism 5 will be explained with reference to FIGS. 2 to 4.

The center of one end 1a of the movable plate 1 in FIG. 2 is supported like a universal joint on a predetermined fixed base, that is, a wall 6 continuous to the bed 3, to allow vertical movement of the other end 1b and both side parts 1c and 1d. It is supported by a support device 7.

This support device 7 only supports one end 1a of the movable plate 1 in the form of a universal joint, but cannot determine the lateral position of the movable plate 1. Therefore, the other end 1b of the movable plate 1 is A positioning device 11 is provided to support the weight of the other end 1b.

This positioning device @ 11 consists of a bar 12 and a lever 14, and the bar 12 is arranged along a center line passing through the center of the support device 7 from approximately the center of the back surface of the movable plate 1 to the other end 1b. .

One end of a lever 14 having a substantially inverted V shape is supported on the bar 12 so as to be slidable along the axial direction of the bar 12 and rotatable around the bar 12, and the other end of the lever 14 is The movable plate 1 is pivotally attached to an attachment point 13.13 on the floor 3, which is a predetermined fixed base, so that movement in the lateral direction is prohibited, and the movable plate 1 is rotatable in the direction of rotation due to the sliding movement of the one end.

With the above-mentioned positioning device 11, the other end 1b of the movable plate can be moved up and down, and both sides 1c, ld can be moved around the bar 12.
The lateral position is determined while being able to move up and down.

One ends of a pair of tilting arms 8a, 8b are pivotally attached to both side portions 1c, ld of the movable plate 1 in the form of a universal joint.

The other ends of these tilting arms 8a, 8b are pivotally supported by a reciprocating mechanism, such as a worm gear mechanism 9a, 9b, which is disposed along the vertical direction of the movable plate 1 on the floor 3, which is a predetermined fixed base.

The worm gear mechanisms 9a and 9b are driven by motors 10a and 10 equipped with a drive mechanism for rotating the worms, such as a reduction gear.
The movable plate 1 is moved in the vertical direction by being driven once by b.

In the tilt drive mechanism 5 having such a configuration, when the two side plates 1c and ld of the movable plate 1 are held horizontally and the other end portion 1b is moved up and down, the worm gear mechanisms 9a and 9b are used as shown in FIG.
Align the positions and move forward and backward.

At this time, the tilting arms 8a and 8b are connected to the other end 1 of the movable plate 1.
b is moved up and down, and one end is slid along the bar 12 while the lever 14 prohibits the lateral movement of the movable plate 1.

Next, when moving both sides 1c and 1d up and down while keeping the height of the other end 1b of the movable plate 1 constant, the worm gear mechanisms 9a and 9b are moved forward and backward in different positions as shown in FIG. let

At this time, each tilting arm 8a, 8b has both side parts 1c.
.

Therefore, the vertical movement of the other end 1b, both side parts 1c, ld of the movable plate 1 is caused by the worm gear mechanisms 9a, 9b.
By arbitrarily selecting the positions of the movable plate 1, the movable plate 1 can be arbitrarily combined, and the inclination of the entire movable plate 1 can be arbitrarily set.

Although the forward and backward mechanisms 9a and 9b use a worm gear mechanism, the arm 8a,
8b may be moved forward and backward.

If such an inclination drive mechanism 5 is provided, the shot position 4 set at one end 1a of the movable plate 1 and the inclination angle of the ball traveling road surface can be arbitrarily set, so that the shot position 4 can be tilted and unstable. It is possible to simultaneously practice putting shots in a comfortable posture and to practice moving the ball along the slope and inserting it into the hole 2.

It should be noted that the movable plate 1 configured in this manner can of course be used for practicing putting shots, but it can also be used for practicing free shots by utilizing the inclined shot position.

15 is a wiper for removing balls rotatably attached to one side 1C of the movable plate 1, and the wiper 15 is attached to one side 1C of the movable plate 1 so that the surface of the movable plate 10 is
one side 1C of the movable plate 1;
It is designed so that it can be set in a state parallel to this and a state rotated at a right angle from this (the state shown by the imaginary line in Fig. 1).

The wiper 15 crosses the surface of the movable plate 1 to the other side 1d at a height sufficient to clean balls remaining on the surface of the movable plate 1.

A gear 17 is provided on the rotation support portion 16 of the wiper 15, and this gear 17 is meshed with a worm 18 disposed parallel to the side portion 1C of the movable plate 1. It constitutes a guide mechanism 19 that moves toward one side 1a.

Reference numeral 20 denotes a drive mechanism, such as a motor, for rotating the worm 18 and guiding and driving the wiper 15, and this is activated to move the wiper 15 when the wiper 15 protrudes from the surface of the movable plate 1. The wiper 15 is operated until it is guided from one end 1a side of the plate 1 to the other end 1b side and then reversed to return the wiper 15 to the one end 1a side again.

The support portion 16 of the wiper 15 is rotated so as to retreat from the surface of the movable plate 1 when the wiper 15 reaches the other end of the movable plate 1 while protruding from the surface of the movable plate 10 or returns to the initial position. The movable plate 1 is moved so that it is stopped and held in a state parallel to one side portion 1C of the movable plate 1.

The wiper 15 can be freely projected and rotated on the movable plate 1 by a predetermined switch mechanism, so that the wiper 15 automatically
In addition to removing the ball from above, it is also possible to remove the ball regressing to the shot position using the ball progress determining means described below.

That is, on both sides 1c and 1d of the movable plate 1, there are photoelectric devices such as light emitters 21a and 21b that block the traveling direction of the ball (from one end 1a of the movable plate 1 to the other end 1b).
and light emitters 22a and 22b are provided, and the photoelectric device determines that the ball is regressing from the other end 1b side of the movable plate 1 toward the one end 1a side, and sends a predetermined signal to the wiper 15.
This is transmitted to the movable plate 1 so as to project it onto the movable plate 1 and rotate it.

With this arrangement, the other end 1b of the movable plate 1 can be
If the movable plate 1 is tilted upward (as shown by the imaginary line b in Fig. 3) by raising the movable plate 1 higher than a The wiper 15 is sensed by the direction determining means, and the wiper 15 is made to project obliquely onto the movable plate 1, and the ball can be pushed to the side of the movable plate 1 and removed.

Note that the guide mechanism 19 for moving the wiper 15 along the side portion 1c of the movable plate 1 is not limited to the above-mentioned worm gear structure, and any other mechanism may of course be used.

Further, each hole 2 is provided with a lid 23 which can be opened and closed flush with the surface of the movable plate 10.

That is, as shown in FIG. 5, a lid 23 having the same cross-sectional shape as the movable plate 1 is hinged to the back surface of the movable plate 1 from the inside of the hole 2, and the lid 23 is always kept closed by the support arm 24. ing.

This arm 24 includes a spring 25 and a contact switch 2.
6, and only when a predetermined input signal is received, the movable element 27 of the contact switch 26 pulls the support arm 24 against the spring 25 to rotate the lid 23 inside the hole 2. I'm trying to keep Hall 2 open.

In this way, only the required holes 2 can be opened and the others can be closed, so the practitioner can freely choose the holes 2 that are far from the putting position 4. You can practice putting shots by selecting one.

In addition, 28 is a hopper-type discharge port for discharging the ball that has entered the hole into a predetermined passage, and 29 is a ball detector that detects the hole-in with its contact 30 and includes a lamp, etc.
A signal is sent to a predetermined display device.

As described in detail above, this invention allows the entire movable board that makes up the putting green to be tilted arbitrarily using a tilting mechanism, and since various tilts can be freely set and practiced, it is possible to practice with a variety of tilts. You can practice effectively and immediately.

In particular, since the shot position can be tilted to match the green, it is possible to perform advanced practice that was not possible with conventional devices, such as practicing shots while the foothold is tilted.

In addition, in this invention, one end of the movable plate is supported by a universal joint-like support device so as to allow tilting, and a positioning device is used to prohibit lateral movement, and both sides are supported vertically by tilting arms. Although it has a simple configuration, it can be operated reliably.

In addition, it is convenient to be able to automatically remove the ball from the movable board by providing a wiper, and it is also possible to practice putting shots of various distances and short distances by selecting desired holes of different distances.
