Description

[Detailed explanation of the idea] The present invention relates to a golf putts training machine.

This machine is used by golfers to practice golf, especially putting. Conventionally, with this type of practice machine, the holes are fixedly placed at appropriate positions on the field board, and the practice A practice machine that hits the ball toward the hole is known. However, with this training machine, the practitioner can only aim at a hole at a fixed position at all times, so it is not possible to expect much effect from practice.

In view of the above-mentioned drawbacks of the conventional training machines, a practice machine is also known in which a plurality of holes are provided on the same field board so that a practitioner can aim at various holes. However, the plurality of holes cannot be placed close to each other or in a straight line as seen from the practitioner. If these holes are close to each other, when a practitioner hits a ball at a particular hole, he or she will be concerned about other nearby holes and will not be able to practice satisfactorily. Furthermore, if the holes are arranged in a straight line when viewed from the practitioner, the practitioner cannot aim at the hole located at the back. As described above, in this training machine, the positions where the holes are arranged are limited, so it is not possible to arrange a large number of holes, and therefore, compared to the above-mentioned training machine, many effects cannot be expected.

Further, according to Japanese Utility Model Publication No. 44-6830, a plurality of holes that can be opened and closed are provided in the field plate, and the putting course can be changed by appropriately changing the opening and closing of these holes. Training aircraft capable of this have also been proposed. However, in this case, opening and closing the holes is very time consuming.

In addition, a rotating plate is provided within the field plate, and holes are provided at appropriate positions within the rotating plate, and by rotating the rotating plate by an appropriate angle, the position of the hole is changed and the putting course is changed. There are also devices that do. However, even with this device, the mode of course change is small and limited.

In view of the above points, it is an object of the present invention to provide a golf putting practice machine that can be used on many different types of putting courses without unnecessarily complicating the device.

Hereinafter, the present invention will be explained based on its embodiments.

FIG. 1 is a perspective view of a golf putt practice machine showing one embodiment of the present invention. First, the general structure and operation of this embodiment will be explained using this figure. The field plate 1 consists of a flexible member 4 such as a shield, and a field surface 5 bonded onto the flexible member 4. The deep part of this field plate 1 is glued to a movable plate 3 as a field plate tilting means.
On the other hand, its front portion extends forward from the training aircraft main body 2 to form a striking portion 5a. In addition, 1 of the flexible member 4
One end is connected to the movable plate 3, and the other end is fixed to the front part 2' of the training aircraft main body 2.

A rotary plate 6 is disposed at the back of the field plate 1 supported by the movable plate 3, and a hole 7 is provided within the rotary plate 6. However, in this case, the center of rotation of the rotating plate 6 and the center of the hole 7 are not the same.

Although the material of the field surface 5 of the field plate 1 is not limited to any particular material, it is preferable to use a sheet made of soft plastic with flocking treatment. This results in
This is because it is possible to obtain a ball rolling condition that is the same as the grass on an actual golf course green. Furthermore, for the same reason, it is desirable that the surface of the rotary plate 6 be treated with flocking.

The field plate 1 is the side plate 2a, 2 of the training aircraft main body 2.
A groove is formed between the field plate 1 and these plates 2a, 2b, and 2c.

An inclined plate 8 is arranged below the field plate 1, and this inclined plate 8 is connected to the side plate 2 of the training aircraft main body 2.
a and the rear side plate 2c are directly fixed, and the one side plate 2b is fixed via a ramp 9. Furthermore, the inclined plate 8 has the side plate 2a side at a higher position, and the side plate 2a side is in a higher position.
It is inclined so that the b side, that is, the ramp 9 side is at a lower position. The inclined plate 8 has a partition plate 8' at its front end for guiding the ball.
Further, as shown in the figure, the ramp 9 is arranged to be inclined forward from the rear side plate 2c along the side plate 2b.

A ball feeder 10 having arms 10a and 10b is arranged in front of the ramp 9, and is rotated about an axis 11 by a drive device (not shown).

Reference numeral 12 denotes a scraping rod extending from a carrier 13 disposed further rearward of the rear side plate 2c of the training aircraft main body 2. The carrier 13 can be moved in parallel within the main body 2 by a drive device (not shown), as indicated by the broken line compound arrow.
moves back and forth along the field surface 5 of the field plate 1 as indicated by compound arrow A. However, usually
The scraping rod 12 is placed close to the side plate 2a.

The practitioner stands at the hitting section 5a provided in front of the field surface 5 of the field board 1, and repeatedly hits the golf ball B, which is also placed on the hitting section 5a, toward the hole 7, thereby practicing putting. will be carried out. Originally, all balls hit by the practice player should go into hole 7, but
Some of them, against the wishes of the practitioners, deviate from the hole 7 and touch the field plate 1 and the side plates 2a, 2b, 2c.
Some of them enter the grooves provided in between, or some of them stop on the field surface 5 because the striking force is too weak. Of the balls that follow these three paths, the ball that enters the groove and the ball that enters the hole 7 both fall onto the inclined plate 8. Inclined plate 8
As mentioned above, since the ball is tilted in the direction of the ramp 9, the ball that has fallen onto the ramp 8 will fall into the ramp 9 due to the inclination. However, the ball that enters the groove between the field plate 1 and the side plate 2b falls directly into the ramp 9, as can be seen from the figure. If a ball follows a path other than the above two paths, that is, a ball stops on the field surface 5, the carrier 13, that is, the scraping rod 12 is activated, thereby forcing the ball into the ramp 9. let it fall to

In this case, there are various possible means for sending an operation start signal to operate the carrier 13, in other words, means for detecting that the ball has stopped on the field surface 5. One example is as follows.

That is, a pair of photoelectric detection elements, for example, a light emitting element and a light receiving element, are attached in advance to the front parts 14 and 15 of the training machine main body 2, and the ball passes through these parts and hits the field surface 5 inside the main body 2. When the vehicle falls into a vehicle, these elements detect it. On the other hand, a second detection element such as a micro switch is attached at an appropriate position within the ramp 9, and when the ball rolls within the ramp 9, this detection element detects it. By arranging the photoelectric detection element and the second detection element in this way, the ball enters the groove or hole 7 between the field plate 1 and the side plates 2a, 2b, 2c, and as a result, the ball enters the ramp 9. When the ball sinks in, both the photoelectric detection element and the second detection element can detect the passage of the ball. However, when the ball stops on the field surface 5, although the photoelectric detection element detects the passage of the ball, the second detection element does not detect it. In this way, if a certain period of time elapses without being detected by the second detection element, it can be known that the ball has stopped on the field surface 5, and therefore, after that certain period of time, the carrier 13
is activated.

The ball that has fallen into the ramp 9 and further rolled down the ramp 9 is then carried upward by the arm 10b of the rotating ball feeder 10. The ball thus carried upward is sent forward through an opening 16 provided in the front part 15 of the main body 2, and is sent forward through the passage 1.
7 and returns to the striking portion 5a of the field surface 5 again. Incidentally, when the arm 10b of the ball feeder 10 rotates as described above, the arm 10a attached on the opposite side naturally rotates to the lower position.
The next ball that has rolled down the ramp 9 will be sent out to the hitting section 5a by this arm 10a.

The general structure and operation of this part training machine are as described above, and the rotary plate 6 of this practice machine is configured to be rotatable within the field plate 1. The position of the hole 7 can be changed.

The mounting means and driving means for the rotating plate 6 will be explained in detail below.

FIG. 2 is a side view showing the inside of the training aircraft main body 2 according to the arrow X in FIG. It is fitted into the plate 1.

On the lower surface of the movable plate 3, two support shafts 19a, 19 are provided on the center line via flanges 18a, 18b.
b are attached, and their supporting shafts 19a,
19b are fitted into the upper ends of struts 21a and 21b, respectively, which are fixed to the bottom plate 20 of the training aircraft main body 2. With this configuration, the movable plate 3 is attached to the support shaft 19a.
and 19b, in other words, it can rotate around the line connecting the support shafts 19a and 19b (corresponding to the center line of the movable plate 3 in this case).

FIG. 3 is a cross-sectional view taken along line Y-Y in FIG.
is tiltable about a support shaft 19a fitted into a support 21a extending from the bottom plate 20. In the figure, only the support column 21a and the support shaft 19a are shown, but the other support column 21b and support shaft 19b are also arranged in the same position.

One end of a link 22 is pivotally attached to the end of the flange 18a having the support shaft 19a, and the other end of the link 22 is pivotally attached to a rotating body 24 attached to the output shaft of a motor 23. These are drive systems for tilting the movable plate 3 as shown by the broken line or the one-dot chain line.

In FIG. 2, the rotating plate 6 has a circular iron plate 6'.
is glued thereto, and a rotating shaft 27 having a gear 26 at its lower end is fixed at the center of the lower surface of the iron plate 6'. This rotating shaft 27 is supported by a bracket 28 via a bearing 25, and the bracket 28 is further fixed to a flange 29 fixed to the movable plate 3.

FIG. 4 is a plan view showing the vicinity of the rotary plate 6 in detail along arrow Z in FIG.
It is fixed to the movable plate 3 by screws or the like.

With the above configuration, the rotary plate 6 is held within the movable plate 3 and is rotatable. In FIG. is engaged with the gear 26 of the rotating shaft 27, so the rotating shaft 27, that is, the rotating plate 6, is rotationally driven using the motor 30 as a driving source. Incidentally, reference numeral 32 is a cam attached to an appropriate position on the rotating shaft 27, and reference numeral 33 is a switch for picking up the movement of the cam 32.

The cam 32 is shaped to have four protrusions equally spaced as shown by broken lines in FIG. 4, and these protrusions cause the microswitch 33 to perform a switching operation. When the motor 30 operates, the rotating shaft 27 and the rotating plate 6 integrated therewith rotate, and as a result, the hole 7 in the rotating plate 6 rotates around the rotation center of the rotating plate (the mounting position of the rotating shaft 27). . At this time, the cam 32 also rotates in the same manner, but when the outer peripheral protrusion of the cam 32 pushes the actuator of the switch 33 appropriately, the micro switch 33 is switched. Taking this as a signal, the operation of the motor 30 is stopped, and thereafter, the motor 30 continues to be in the stopped state unless an external operation signal is given. As is clear from the above explanation, the hole 7 is connected to the cam 32.
In particular, in this embodiment, the four protrusions of the cam 32 are arranged at equal intervals, so the possible positions of the hole 7 are indicated by the solid line in the figure. Position or dashed line 7
The positions are a, 7b, and 7c.

Members 34, 35, 36, 37 indicated by broken lines in the figure
are partition plates arranged on the inclined plate 8, and these partition plates are arranged at positions 7a, 7 that the hole 7 can take.
It is arranged so as to surround b and 7c. By arranging the partition plates 34, 35, 36, and 37 in this way, if the hole 7 is located at the solid line position or 7a, 7
No matter where it is on holes b or 7c, that hole 7
The ball that entered the partition plate 35 and the partition plate 36
It will roll out into the ramp 9 through the outlet 38 formed by the. A switch 39 is arranged at the outlet 38, and the ball rolling out from the outlet 38 is detected by this switch.
Other partition plates 41, 42, and 43 are arranged within the range surrounded by the partition plates 34 to 37, but these partition plates prevent the ball from hitting the rotary plate drive device such as the motor 30. This is to prevent it. The motor 23 disposed at the lower part of the rear side plate 2C is a motor for tilting the movable plate explained in FIG. 3. The movable plate tilting motor 23 or the rotary plate driving motor 30 is configured to start operating by the switching operation of the switch 39.

Since the mounting means and driving means for the rotary plate 6 are as described above, in FIG. 4, if the ball hit by the practitioner enters the hole 7,
The ball falls onto the inclined plate 8, then rolls on the inclined plate 8 along the partition plates 34, 35 or the partition plates 41, 42, etc., and then rolls down from the exit 38 into the ramp 9. The subsequent path of the ball that falls into the ramp 9 is as explained in FIG. When the ball passes through the outlet 38, the switch 39 performs a switching operation, which activates the rotary plate drive motor 30 and drives the rotary plate 6.
rotates. Due to the rotation of the rotary plate 6, the hole 7 is
For example, it rotates clockwise, but hole 7 is 7a.
When the position is reached, at that point the protrusion of the cam 32 pushes the actuator of the switch 33, and the switch 33 performs a switching operation. This switching action causes the motor 30 to stop,
Therefore, the hole 7 remains at position 7a. Therefore, the next time the practitioner hits, he will aim at hole 7, which has been moved to position 7a.

In this way, each time the ball enters hole 7, hole 7 sequentially shifts its position to 7a, 7b, and 7c, so the practitioner has to aim for a different putting course each time, making it easier to You can get great practice results. In addition, the hole 7 in this example is designed so that its position changes with the rotation of the rotary plate 6, so it is not possible to open the hole 7 in the conventional manner.
The hole can be moved much more easily than a closed hole. Furthermore, the holes 7 can be positioned in a straight line as seen from the practitioner, as shown at 7a and 7c, which is not possible with conventional machines that drill multiple holes on the field board. I can't.

Furthermore, in this embodiment, since the movable plate 3 can be tilted by the switching operation of the switch 39, the variety of putting courses can be further increased by rotating the hole 7. For example, when a ball enters the hole 7 in FIG.
is rotated to displace the hole 7 to the position 7a, and then when the ball enters the hole 7 displaced to 7a and a switching action is obtained, the movable plate tilting motor 23 is activated. By doing so, the movable plate 3 is tilted as shown by the broken line or the dashed line shown in FIG. As a result, although the position of the hole 7 does not change, the practitioner aims at a different putting course by the amount that the movable board 3 is tilted, that is, the field board 1 is tilted. Note that when tilting the movable plate 3, the field plate 1 in the range from the movable plate 3 to the front part of the training aircraft main body 2 will be twisted, but the field plate within this range is preliminarily attached to the flexible member 4. Therefore, no distortion occurs on the field surface due to the above-mentioned twisting action. Further, although means for stopping the movable plate 3 are not particularly shown in FIG. 3 or other drawings, the same means as the cam 32 and the switch 33 for stopping the rotary plate 6 can be used for this purpose. Good.

By alternately repeating the rotation of the rotary plate 6 and the tilting of the movable plate 3 in this manner, the types of putting courses to be aimed at are increased, and the effectiveness of practice is thereby increased.

The present invention has been explained above with reference to one embodiment.
The present invention is not limited to this example, and various modifications are possible.

For example, a configuration in which the rotary plate 6 is rotated manually without using a rotary plate drive system such as the rotary plate driving motor 30 may be used.

Moreover, not only one hole 7 but also a plurality of holes can be provided in the rotary plate 6.

Furthermore, the cam 32 can have various shapes other than the one having four equally spaced protrusions, so that the resting position of the hole 7 can be set in any manner.
