Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a golf practice table capable of practicing slope shots.
[0002]
[Prior art]
Most golf enthusiasts practice playing on the golf course by actually hitting the ball through the driving range.
[0003]
A general golf driving range has a structure in which a flat fixed floor is divided into a plurality of hitting bats, and a rubber mat is usually placed at a position where a user takes a stance in each batting bat. An artificial turf mat having a hole through which a rubber tee is passed is provided at a position where the turf is placed, and a ball supply device may be provided in front of the artificial turf mat.
[0004]
A batting user puts a ball on an artificial grass mat or a rubber tee passed through a hole, takes a stance on the rubber mat, and hits the ball with a required club to practice a shot.
[0005]
[Problems to be solved by the invention]
On the other hand, most normal golf courses have undulations because they use terrain undulations, and for this reason, the next wood or iron from the position where the shot ball fell and stopped When performing a shot according to (1), a shot in a situation different from a shot on a flat surface such as a toe down, a toe up, a left foot down, a left foot up, that is, a slope shot is required.
[0006]
For example, when the toes are lowered, it is easy to produce a sliced ball, when the toes are raised, the hook ball is likely to be produced, and when the left foot is lowered, the ball is difficult to rise, and when the left foot is raised, the ball is raised and the distance is difficult to be obtained. . For this reason, the player deals with adjusting the position of the stance, the selection of the club, and the like based on experience and feeling according to the situation such as the toe down, the toe up, the left foot down, and the left foot up. In the case of a shot with a putter, the putting direction and strength are adjusted according to the inclination.
[0007]
Therefore, most golfers have a desire to practice shots on an inclined surface at a golf driving range as in a golf course. However, as described above, a normal flat driving surface has a flat surface with a fixed batter. Therefore, it is not possible to practice slope shots other than flat surfaces.
[0008]
Also, in the case of the conventional practice putter green, the putting practice for coping with the inclined surface is performed in the same manner, but it is not possible to have a free inclination.
[0009]
The present invention has been made to solve such conventional problems, and provides a golf practice table that can freely practice slope shots such as toe-down, toe-up, left-foot down, and left-foot up. It is an object.
[0010]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
1 to 3 show an example of a basic configuration of a golf practice table to which the present invention is applied. A golf practice shot table 1 is positioned at the apex of a plane triangle in a lower fixing portion 2. The tilting jack 3 is provided so as to be tiltable.
[0019]
The tilting jack 3 includes a jack shaft 5 that is moved up and down by a motor 4 provided in the fixed portion 2, and a pin joint 6 for allowing the shot stand 1 to tilt at the upper end of the jack shaft 5. . Furthermore, a free connection comprising a spring 7 or the like that supports the tilting jack 3 is allowed between the tilting jack 3 and the fixed portion 2 so as to allow a change in the horizontal interval between the pin joints 6 due to the tilting of the shot base 1. Means are provided.
[0020]
Further, between the center of the shot table 1 and the lower fixed part 2, there is a center column 11 that allows the shot table 1 to move up and down but restricts horizontal movement and rotation. Is provided.
[0021]
The center column 11 includes a plurality of (four in FIG. 3) vertical slide bush shafts 12 fixed vertically on the fixed portion 2, and a vertical block 13 capable of moving up and down along the vertical slide bush shafts 12. And a free bearing comprising a cross-shaped bearing 14 provided between the elevating block 13 and the shot table 1 and supporting the shot table 1 in a tiltable manner.
[0022]
As shown in FIG. 3, the free bearing including the cross-shaped bearing 14 or the like is configured such that the X-direction shaft 15 a of the cross-shaft 15 having the orthogonal X-direction shaft 15 a and the Y-direction shaft 15 b is placed on the lifting block 13 by the bearing 16. The Y-direction shaft 15b is attached to the lower surface of the shot table 1 by a bearing 17 so that the shot table 1 can rotate in the B direction.
[0023]
Therefore, according to the center column 11, when the shot base 1 is tilted by expansion / contraction of the tilt jack 3, the shot base 1 is prevented from moving or rotating in the horizontal direction.
[0024]
A rubber mat 18 is placed at a position where the user on the shot table 1 takes a stance, and an artificial turf mat 20 having a hole 19 through which a rubber tee passes is provided at a position where a ball is placed. .
[0025]
Further, a fixed floor 21 having substantially the same height as that of the shot table 1 is provided on the outer periphery of the shot table 1, and the user moves from the fixed floor 21 onto the shot table 1 to perform shots. Practice is to be done. Further, a biting prevention plate 22 for preventing biting between the shot table 1 and the fixed floor 21 is provided at the periphery of the shot table 1 and the lower part of the fixed floor 21 facing the periphery.
[0026]
Further, as shown in FIG. 2, the tilting jack 3 is operated on the fixed floor 21 close to the shot base 1 to lower the toe, the toe, the left foot, the left foot, or a combination of them. When practicing slope shots, there is provided an operation panel 23 for instructing the tilt direction and tilt angle of the shot table 1, and the operation panel 23 is operated by button operation etc. It is preferable that can be selected step by step.
[0028]
As shown by the solid line in FIG. 1, if the shot stand 1 is in a horizontal state, a ball is placed on a rubber tee or artificial turf mat 20 and a stance is taken on the rubber mat 18. You can practice shots on the horizontal plane.
[0029]
When practicing slope shots such as toe down, toe up, left foot down, left foot up, etc., the operation panel 23 is operated to incline the shot table 1 in a predetermined direction at a predetermined angle.
[0030]
For example, in the case of inclining forward as shown by an imaginary line in FIG. 1, it is possible to practice a forward-declining slope shot. At this time, if the ball does not stop stably on the artificial turf mat 20 due to the inclination of the shot table 1, a method of forming small and vertical grooves 20 'as shown in FIG. Can be adopted.
[0031]
In addition, when the shot table 1 is tilted as described above, if the shot table 1 sinks from the fixed floor 21, the ball hit by the step may be rebounded. Tilt control is carried out so that it may become the same level or more with respect to the floor 21. FIG.
[0032]
Since the shot table 1 is tilted by the tilt jack 3 provided at three points, the shot table 1 can be arbitrarily tilted by simple control, and the tilt jack 3 has a pin. Since the joint 6 is provided, it is possible to follow the tilting of the shot table 1 and further, since the spring 7 is provided between the tilting jack 3 and the fixed portion 2, the shot table 1 can be moved by the expansion and contraction of the tilting jack 3. Even if the distance between the pin joints 6 changes when tilting, the tilting jack 3 can be allowed to tilt by the free connecting means including the spring 7 or the like.
[0033]
At this time, since the center part of the shot table 1 is supported by the center column 11, the shot table 1 is prevented from moving or rotating in the horizontal direction. When the shot stand 1 moves up and down due to the expansion and contraction of the tilting jack 3, the center column 11 follows the up / down sliding bush shaft 12, and the lifting block 13 moves up and down. It is possible to follow freely by a free joint consisting of 14 etc.
[0034]
4 to 6 show an example of the embodiment of the present invention applied to the basic configuration of FIG. 1, and in the central portion of the shot table 1 configured in the same manner as FIGS. 1 and 2, A recess 24 is formed so as to protrude downward, and three points are supported in the recess 24 by an inner tilting jack 25 having the same configuration as the tilting jack 3, and the upper center similar to the center column 11. An inner shot stand 27 supported by a column 26 so as to be tiltable is provided.
[0035]
4 to 6, for example, when practicing a 10 ° forward-declining slope shot as shown in FIG. 6, the shot table 1 is inclined 3 ° and the inner shot table 27 is moved to the shot table 1. By tilting 7 ° with respect to the angle, it is possible to make a total tilt of 10 °. Therefore, by distributing the tilt angle by the shot table 1 and the inner shot table 27 in this way, the step difference in the slope shot is reduced. Therefore, it is possible to make the transfer easy and safe.
[0036]
Also, since the outer shot stand 1 is large, putting practice is possible on this stand. In addition, by linking the above-described apparatus with a golf play simulation game that is performed toward the golf course image on the screen, it is possible to play better simulated play on the golf course.
[0037]
The present invention is not limited to that shown in the above embodiment, and the tilting jack 3 can be an arbitrary number of three or more points, and the shapes of the shot table 1 and the inner shot table 27 are as follows. Of course, various shapes such as a rectangle or a circle can be used, and various modifications can be made without departing from the scope of the present invention.
[0038]
【The invention's effect】
