Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a golf practice table, and more specifically, the invention relates to a golf practice table, and more specifically, a mountain or valley-like place where a golf ball should be hit in accordance with the topography of an actual golf course. Concerning a golf practice table that can reproduce points and locations.

[Conventional technology]

As is well known, many golf practice tables have been put into practical use.

The original form was a practice device that allowed a person to sit on a platform and set a golf ball to be hit on either side, for example, in the X direction, allowing the player to accurately hit a golf ball in an awkward position on unfavorable terrain. However, as the level of sophistication progressed, the platform on which a person could sit and the golf ball to be hit could be tilted not only in one direction, but also in the Y direction perpendicular to the other. A device has been proposed that can be tilted 360 degrees, reproduces terrain conditions that more closely match the undulating topography of an actual golf course, and enables ball-hitting practice that is more similar to playing on an actual golf course. .

One of these conventional types usually has a lower frame, a middle frame, and an upper frame, and the middle frame is tiltable in the X direction with respect to the lower frame, and the upper frame is tiltable in the X direction with respect to the middle frame. This is a golf practice table that can be tilted in the Y direction, which is 90 degrees different from the previous direction.

[The problem that the idea aims to solve]

As described above, in the above conventional technology, the upper frame, that is, the upper platform on which a person rests and the golf ball to be hit is set, can be tilted freely in the X direction and the Y direction. Compared to tilting devices, this device offers greater freedom of use during practice, but after several studies by the inventor,
It was found that the following problems occurred.

That is, although the upper frame (upper platform) can be tilted 360 degrees in any direction, a person can sit on the upper frame, and at the same time, a golf ball to be hit can also be placed on the upper frame. Therefore, no matter what direction the golf ball is tilted, the relative relationship between the person and the golf ball will always be the same whether it is flat or tilted. That is, the distance between the person's standing position and the golf ball, and the inclination of the person and the golf ball with respect to the ground surface are always the same.

However, on an actual golf course, players may stand on a flat surface or on a sloped surface, but the golf ball may be located at the top of a mountain, It may be located at the bottom of a valley. Therefore, in such cases, it is not possible to practice sufficiently using the conventional golf practice table.

Therefore, the main purpose of the present invention is to provide a practice device that allows you to hit a golf ball located at the top of a mountain or at the bottom of a trough, and to improve the performance of an actual golf course with more undulations. The goal is to enable practice that is similar to playing in the game.

Still another object is to provide an apparatus that allows a player to practice in a situation where the place where the player stands is substantially flat and the golf ball to be hit is at an angle.

[Means to solve problems]

In order to achieve the above object, the present invention has the following technical means. That is, to explain this using the reference numerals in the attached drawings corresponding to the embodiments, the present invention has a lower frame 1, a middle frame 2, and an upper frame, and a means for tilting the middle frame 2 in the X direction with respect to the lower frame 1. In the golf practice table, which can be tilted along the X direction by P, and the upper frame can be tilted in the Y direction, which is 90 degrees different from the X direction with respect to the middle frame 2; The upper frame is divided into two at the center, and the left and right upper frames 3A and 3B are connected to each other by a pair 4, and the above-mentioned Y-direction tilting means Q and the upper left frame 3A and the upper right frame 3B are respectively attached.
A Y' direction tilting means R is attached, and a Y direction tilting fulcrum 31 is provided at a position away from the position of the third pair 4 of the upper left frame 3A, which is divided into two, and the middle frame 2 is moved in the X direction with respect to the lower frame 1. By tilting the left and right upper frames 3A and 3B in the X direction, when the left upper frame 3A having the tilting fulcrum 31 is tilted in the Y direction, the upper right frame 3B tilts Tilt symmetrically in the Y' direction with the position of the pair 4 as the boundary,
The left and right upper frames 3A, 3B as a whole have a valley or mountain shape, and only the upper right frame 3B has a shape of a valley or a mountain.
This golf practice table is characterized in that when it is tilted in the Y' direction, it can independently tilt in the Y' direction.

In the above, one upper frame 3A, that is, the left frame, is sectioned as a table A on which a person stands, and the other right frame 3B is sectioned as a table B on which a golf ball to be hit is set.

[Effect]

With the above configuration, by operating the X-direction tilting means P, the middle frame 2 is tilted left and right in the X-direction. Then, the upper frame, that is, the table A on which a person stands and the golf ball setting table B, similarly tilt left and right in the X direction.

Next, when the Y-direction tilting means Q for the upper left frame 3A attached to the middle frame 2 is operated, the platform A on which the person is placed tilts in the Y-direction using the tilting fulcrum 31 as the fulcrum.

Then, the golf ball setting table B, which is connected to the table A on which the person is placed, via a pair 4, also tilts, so that the table A on which the person is placed and the table B on which the golf balls are set are connected. It has a trough-like or mountain-like shape with the boundary at point 4. Further, when the upper right frame 3B and the Y' direction tilting means R which partition the table B on which the golf ball is set are operated, only the golf ball setting table B is tilted along the Y' direction.

In this way, when looking at the table A for people to sit on and the golf ball setting table B as a pair, it is possible to reproduce a mountain-like or valley-like topography that is very similar to an actual golf course. You can practice hitting a golf ball as close as you would play. In addition, regardless of the levelness or inclination of the table A for people to sit on, only the golf ball setting table B can be made horizontal or tilted as desired, so that the terrain can be more closely resembling that of an actual golf course. can be reproduced.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a plan view of the golf practice table of this example, which consists of a lower frame 1 placed on the ground, a middle frame 2 located in the middle,
Table A and golf ball C located on the upper level for people to stand on.
The upper left frame 3 separates the table B on which the
A, has the upper right frame 3B. The upper left frame 3A and the upper right frame 3B are connected to each other by a chisel 4.

Now, of the above, the relationship between the lower frame 1 and the middle frame 2 will be explained according to FIGS. 2 and 3. That is,
A motor 6 that operates in forward and reverse directions is disposed on a bar 5 installed in the center of the lower frame 1, and a pair of motors, for example, are installed at a predetermined interval on another bar 7 installed in a direction orthogonal to the bar 5. Output conversion devices 8 and 9 consisting of bevel gears and the like are provided, and the forward/reverse motor 6 and the output conversion devices 8 and 9 are connected as follows.

That is, the sprocket wheel 11 is attached to the output shaft 10 of the forward/reverse motor 6, and the transmission shaft 1 between the sprocket wheel 11 and the output converters 8 and 9
The two sprocket wheels 13 are connected by a belt 14, and the two output conversion devices 8, 9 are connected to each other by a belt 14.
a screw shaft 15 extending vertically upward from each;
16 are screwed onto bearing bodies 19 and 20 disposed between bars 17 and 18 that span the middle frame 2, respectively.

As a result, if the forward/reverse motor 6 is driven in the forward or reverse direction, the screw shafts 15, 16 of the output converters 8, 9
rotates in the forward and reverse directions or in the reverse direction, so that the middle frame 2 is tilted in the direction of the arrow X in FIG. 2 or 3. Of course, in order to enable this tilting in the X direction, both ends of the middle frame 2 are pivotably supported by the X direction tilting fulcrum 21 supported by the lower frame 1, and the middle frame 2 is Each bearing body 19, 20 is itself rotatably supported 22 between bars 17, 18. These constitute the X-direction tilting means P.

Next, the relationship between the middle frame 2, the left frame 3A, and the upper right frame 3B will be described in detail with reference to FIGS. 4 and 5. That is, a forward/reverse motor 23 is disposed in the middle frame 2, and an output converter 24 is also provided to convert the output shaft 2 of the forward/reverse motor 23.
A belt is placed between the sprocket wheel 26 on the top 5 and the sprocket wheel of the output conversion device 24, and a threaded shaft 27 extending vertically upward from the output conversion device 24 is placed on the upper left frame 3A. It is screwed onto a bearing body 30 between the bars 28 and 29 of. As a result, the screw shaft 27 operates in the forward or reverse direction due to the forward or reverse drive of the forward/reverse motor 23, so that the upper left frame 3A moves in the direction of the arrow Y in FIG. 4 and the direction of the arrow Y in FIG. Although it is inclined,
To make this possible, the upper left frame 3A is rotatably supported at both ends by Y-direction tilting supports 31 supported on the middle frame 2, and the bearing body 30 itself also rotates. Freely movable pivot support 32
has been done.

Incidentally, the Y-direction tilting fulcrum 31 of the upper left frame 3A is located at a location slightly to the left in FIG. It is something that exists. These constitute the Y-direction tilting means Q.

Next, the tilting means for the upper right frame 3B, that is, the golf set table B will be explained. That is, a forward/reverse motor 33 is attached to the middle frame 2, and two output converters 35, 36 are arranged at a predetermined interval on a plate 34 suspended over the middle frame 2. sprocket wheel 38 on the output shaft 37 and two output conversion devices 35, 3
A belt 41 connects the six sprocket wheels 40 on the connecting shaft 39. On the other hand, each pair of bars 42, 43 arranged on the middle frame 2,
Output screw shafts 48, 49 extending above the output converting devices 35, 36 are screwed onto bearing bodies 46, 47 disposed between the bearing bodies 44, 45.

As a result, the two screw shafts 48 and 49 rotate in the forward and reverse directions or in the reverse direction, respectively, by the forward and reverse operations of the forward and reverse motor 33, so that only the upper right frame 3b rotates in the same direction as the Y direction. It is something that leans in one direction. In this case, when only the upper right frame 3B is tilted in the Y' direction, the fulcrum of the tilt is the 4 parts of the second pair, but in order to make this tilting in the Y' direction possible, the bearing body 46, 47 itself is rotatably supported by a shaft 50, and the screw shaft 4
8 and 49 are connected to a bevel gear in the output conversion device (not shown) via a known universal joint 51 that can transmit rotational torque even if the output conversion devices 35 and 36 are tilted. These constitute the Y' direction tilting means R.

Therefore, a stand A for people to stand on is divided on the upper left frame 3A, and a stand B for setting a golf ball on the upper right frame 3B. A board is placed on top of the left and right upper frames 3A and 3B, a rubber mat is placed on stand A for people to sit on, artificial turf is laid on stand B for setting golf balls C, and other designs are created as appropriate. It is an addition.

In order to make the explanation easier to understand, Figure 2 shows only the relationship between the lower frame 1 and the middle frame 2, and in reality, the upper right frame 3B and the upper left frame 3A are placed above this, and they are arranged similarly. Third
The figure also shows the related parts between the lower frame 1 and the middle frame 2, with other parts omitted.Furthermore, FIG. It is omitted,
Similarly, Figure 5 also shows the middle frame 2 and the left and right upper frames 3.
This shows the related parts of A and 3B.

A series of operations based on the above configuration will be explained with reference to Fig. 7 onwards. Fig. 7 shows the case where the lower, middle and upper frames 1, 2, 3A and 3B are all flat. In this case, the X-direction tilting means P, the Y-direction tilting means Q and the Y'-direction tilting means R are all kept neutral without tilting in any direction.

Next, only the X-direction tilting means P is driven. That is, the forward/reverse motor 6 is operated in the forward or reverse direction to drive the pair of screw shafts 15 and 16. Since the screw shafts 15 and 16 on one side and the other side rotate in opposite directions, the middle frame 2 is moved to the eighth position around the X-direction tilting fulcrum 21.
Tilt to either direction in the X direction as shown in the figure. Therefore, the upper frames 3A and 3B, that is, the stand A on which the person stands and the golf ball C
The setting table B is tilted to either direction in the X direction.

Further, only the Y' direction tilting means R is driven. That is, the forward/reverse motor 33 is operated in the forward or reverse direction to drive the pair of screw shafts 48, 49. Since the screw shafts 48 and 49 on one side and the other side rotate in opposite directions, the upper right frame 3B tilts in the Y' direction as shown in FIG.
That is, it tilts with the young pair 4 as a fulcrum. At this time, since the bearing bodies 46, 47 onto which the screw shafts 48, 49 are screwed are supported by a shaft 50, this inclination is allowed. Of course, this Y' direction inclination and the above-mentioned X direction inclination can also be combined.

Subsequently, only the Y-direction tilting means Q is driven. That is, the forward/reverse motor 23 is operated in the forward or reverse direction to move the screw shaft 27 forward or backward. Then, since the relative position with the bearing body 30 is different, the upper left frame 3A tilts in the Y direction. In this case, since it is tilted about the Y-direction tilting fulcrum 31, the upper right frame 3B is also connected by the second pair 4, so it is symmetrical with respect to the upper right frame 3A with the third pair 4 as the boundary. lean towards. This state is shown in FIG. 5, FIG. 10, or FIG. 49 are connected by a universal joint 51.

Although each operation is shown individually in the above, it is also possible to combine these operations. and,
A person who practices golf performs this control while standing on the platform A by operating the V, W, and N control buttons as illustrated in FIG.

As is clear from the above example, the table A on which the person is placed and the table B on which the golf ball C is placed can be shaped like a mountain or a valley with the boundary at the third pair 4, so that It is possible to reproduce situations tailored to the terrain, and it is possible to practice hitting a golf ball in a way that is very similar to playing on an actual golf course.

[Effect of idea]

As detailed above, according to this invention, not only can both the stand A on which a person stands and the stand B on which the golf ball is set be tilted in all directions,
The above-mentioned tables A and B can be shaped like a valley or a mountain, and of course, it is also possible to hold one of the above-mentioned tables A and B and tilt the other. In contrast, since it is possible to reproduce a shape that closely resembles the topography of an actual golf course, it is possible to practice more closely resembling play on an actual golf course.

In addition, this device itself is small and compact, making it easy to transport and install.
