Golf practice pad

Abstract

Conventional golf practice bench inventions often use hydraulic equipment or motors to rotate and generate power, resulting in a complex structure. [Solution] A golf practice stand is provided comprising a base fixed to the ground or floor, a scaffolding plate pivotally supported on a pivot shaft provided on the base, and a ball set plate held by a guide member and arm attached to the back of the scaffolding plate, with a tee portion on its upper surface for placing a golf ball. The scaffolding plate moves up and down in a direction perpendicular to the axial direction of the pivot shaft, and the scaffolding plate is held at an inclined angle by inserting an adjustment support column into the base and the scaffolding plate. This golf practice stand has a simple structure, yet can reproduce shots from various golf courses.

Description

Technical Field

[0001] The present invention relates to a golf practice table provided with a scaffold plate that can simulate a scaffold state similar to a golf course, unlike a golf driving range, when practicing golf, and a corresponding ball set plate.

Background Art

[0002] In a golf driving range, the practice is always on a flat scaffold. However, in an actual golf course, there are many undulations, and a miss shot occurs due to an unusual posture and a deviation in the position of the center of gravity.

[0003] For example, on a toe-up scaffold, the center of gravity is biased backward and the posture is looking up, so it is easy to miss the shot by hitting under or over the ball. Therefore, there is a way to hit the ball according to the scaffold state, but since there is no slope in a golf driving range, it is difficult to practice according to the scaffold state.

[0004] As the state of the scaffold on a golf course, generally, four typical scaffold states are toe-up, toe-down, left-foot-down, and left-foot-up. However, a golf practice table having a scaffold plate that reproduces these four scaffold states has been demanded. Furthermore, on a golf course, the ball is also on an undulating ground, and since the slope of the scaffold and the slope of the position where the ball is located are different, the height and distance between the scaffold and the ball vary depending on the scaffold state. For example, in the case of a toe-up, the ball is at a higher position than the scaffold, but the distance becomes shorter or longer depending on the slope of the position where the ball is located. In the case of a toe-down, it becomes lower and farther. As the above-described golf practice device, it is desirable to be able to set the distance and height from the ball separately from the scaffold plate.

[0005] As a golf practice device, there is an invention of Patent Document 1. In this invention, a main body having artificial turf on the upper surface, a base located below the main body, and a tilting means that is rotatably connected to the main body on one side and tilts the main body about one side of the main body are provided, and the base and the main body are configured to be able to be rotated. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2006-223515 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] The invention described in Patent Document 1 employs a method of changing the inclination angle of a scaffolding plate using hydraulic equipment and rotating it with a motor to generate power. However, when this invention is introduced to a golf driving range, expensive new equipment such as hydraulic cylinders and hydraulic control systems are required, and the structure of a golf driving range becomes complex due to the large number of golf practice bays and the hydraulic piping equipment.

[0008] Furthermore, in Patent Document 1, as a method for tilting scaffolding, the end of the base and the end of the main scaffolding plate are connected by hinges to form a pivot axis, a contact point is provided at the rear of the base and connected to the rear contact point of the scaffolding plate with a diagonal member, and the tilt angle is changed by oscillating so as to change the height of the diagonal member. As a result, the diagonal members, reinforcing members, and other components become larger, increasing both weight and cost.

[0009] Furthermore, while changing the height of the diagonal members is a common method for altering the inclination angle of the scaffolding plate, as described above, the invention in Patent Document 1 does not consider the bending moment. The bending moment is the value obtained by multiplying the applied force by the distance from the point of application. In the case of a golf practice platform, let A be the perpendicular point from the intersection of the scaffolding plate and the diagonal member to the base, and let B be the intersection of the diagonal member and the base. The distance from A to B is used as the distance from the point of application. Since the inclination angle of the scaffolding plate is very low, between 0 and 15 degrees, the smaller the inclination angle, the longer the distance from the point of application, resulting in a larger bending moment. This leads to larger components such as diagonal members and reinforcing members, increasing both weight and cost. [Means for solving the problem]

[0010] To solve the above problems, the invention of claim 1 is a golf practice platform characterized by comprising a base fixed to the ground or floor surface, a scaffolding plate pivotally supported on a pivot axis provided on the base, the scaffolding plate moving up and down in a direction perpendicular to the axial direction of the pivot axis, and the scaffolding plate being held at an inclined angle by inserting an adjustment support column into the base and the scaffolding plate.

[0011] Furthermore, the invention of claim 2 is characterized in that the top surface of the adjustment support is inclined at an angle such that the entire top surface of the adjustment support is in contact with the scaffolding plate, and the contact surface between the top of the adjustment support inserted into the scaffolding plate and the scaffolding plate is in contact with the scaffolding plate; the invention of claim 3 is characterized in that the base has a front wall, a rear wall and side walls and is a box structure in which the scaffolding plate can be stored; the invention of claim 9 is characterized in that a ball set plate is held by a guide member attached to the back of the scaffolding plate and an arm portion that extends and retracts along the guide member, and a tee portion for placing a golf ball is provided on the upper surface of the ball set plate, and the distance between the ball set plate and the scaffolding plate can be freely changed by the extendable arm portion.

[0012] Furthermore, the invention of claim 6 is characterized in that the front wall of the base has a pivot shaft and the side wall near the rear wall has a groove, the adjustment support is fitted into the groove and fixed, and in order to more firmly hold the adjustment support, fixing walls are provided in front of and behind the adjustment support, the invention of claim 7 is characterized in that a U-shaped cross-section fitting is attached to the front wall side end of the scaffolding plate, and fittings with a first pivot shaft hole at the tip are attached to both sides, similarly a U-shaped cross-section fitting is attached to the top end of the front wall, and fittings with a second pivot shaft hole at the tip are attached to both sides, and the pivot shaft is the The invention of claim 8 is characterized by passing through a first pivot shaft hole and a second pivot shaft hole, wherein the adjustment support column is U-shaped and has support holes at both ends that support shaft penetration, the base has a support shaft connecting the side walls and a support wall that supports the adjustment support column to stand vertically, and by passing the support holes of a plurality of adjustment support columns of different widths through the support shaft, a plurality of adjustment support columns are housed inside the base, and by making one of the plurality of adjustment support columns stand upright, the scaffolding plate is held at a predetermined inclination angle. [Effects of the Invention]

[0013] In this invention, a plurality of height-adjustable support columns are provided on the base according to the inclination angle, and the top of the scaffolding plate is processed to be inclined according to the inclination angle so that the entire contact surface between the scaffolding plate and the height-adjustable support columns is in contact, Because the load from the scaffolding plate acts in the direction of the axis of the height adjustment support, the bending moment is reduced. This eliminates the weakness of long members, which are strong in compression but weak in bending moment. Furthermore, large diagonal structural members are unnecessary, and reinforcing members at the intersection of the diagonal members and scaffolding plates are also eliminated, reducing weight. In addition, by reinforcing the height adjustment support columns by installing fixed walls at the front and rear, and by fitting reinforcing columns of a height corresponding to the inclination angle between the front and rear ends of the side walls and the inner side walls, the scaffolding plates become stable. Moreover, power equipment for tilting the scaffolding plates is not required, making it possible to provide an inexpensive golf practice platform.

[0014] In the invention of claim 5, an outer frame is provided on the outer periphery of the scaffold plate, and artificial turf or a floor-mimicking mat can be removed by a detaching material on the upper surface of the scaffold plate. Different types of artificial turf can be exchanged, enabling simulation of various installation states of golf balls. Also, it is easy to replace the artificial turf with new artificial turf when the artificial turf is worn out.

[0015] In the invention of claim 7, a fitting having a first swing hole at the tip of the scaffold plate and a second swing at the top of the front wall is provided, and the scaffold plate is inclined by a swing shaft passing through each hole, thereby preventing breakage due to fatigue of bolt holes such as hinges used for conventional swinging.

[0017] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are examples for explaining the present invention, and the present invention is not intended to be limited only to those embodiments. Further, the present invention can be variously modified without departing from its gist. Furthermore, the same reference numerals are given to the same components in each drawing as much as possible, and duplicate explanations are omitted.

Mode for Carrying Out the Invention

[0018] <Embodiment 1> The golf practice table B according to Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 4. FIG.  1 is an external perspective view of the golf practice table B according to the present invention, FIG. 2 is a right side view of the golf practice table B according to Embodiment 1 of the present invention, FIG. 3 is a plan view of the golf practice table B according to Embodiment 1 of the present invention, and FIG. 4 is a right side view showing the types of the adjustment struts 9 of the golf practice table B according to Embodiment 1 of the present invention.

[0019]

[0020] As shown in FIGS. 1 to 3, the golf practice table B includes a base 4 fixed to the ground or the floor surface, and a scaffold plate 5 pivotally supported by a swing shaft 7 provided on the base 4. The scaffold plate 5 moves up and down in a direction D orthogonal to the axial direction of the swing shaft 7, and the scaffold plate is held at an inclination angle by inserting an adjustment strut 9 between the base 4 and the scaffold plate 5.Furthermore, the back of the scaffolding plate 5 is equipped with a ball set plate 12, which is held by a guide member 23 and an arm portion 24 and has a tee portion 26 on its upper surface for placing a golf ball. Details of the ball set plate 12 will be described later, but the ball set plate 12 is provided for placing a golf ball and for adjusting the horizontal position between the golfer and the golf ball. For this reason, it is preferable that the ball set plate 12 be provided on sides 53 and 54, which are the side edges of sides 51 and 52, rather than on side 52, which is the opposite side of side 51 on the pivot axis 7 side of the scaffolding plate 5.

[0021] Furthermore, the ball set plate 11 installed on side 52 does not need to be held by the guide member 23 and arm portion 24, as the golf ball is placed on the upper part of the slope and therefore does not need to be held by the guide member 23 and arm portion 24.

[0022] Furthermore, the contact surface between the top of the adjustment support 9 inserted under the scaffolding plate and the scaffolding plate 5 may be such that the top surface of the adjustment support 9 is inclined at an angle such that the entire top surface of the adjustment support 9 contacts the scaffolding plate 5. Figure 4 is an example, but one of the adjustment support 9, 9a, has its top 91a inclined at an installation angle aR, similarly, one of the adjustment support 9, 9b, has its top 91b inclined at an installation angle bR, and one of the adjustment support 9, 9c, has its top 91c inclined at an installation angle cR. For example, it is preferable that the installation angle aR is 15 degrees, the installation angle bR is 10 degrees, and the installation angle cR is 5 degrees, but the angles are not specified here.

[0023] Furthermore, the base 4 may have a front wall 1, a rear wall 2, and side walls 3, as shown in Figures 1 to 3, and may be a box structure that can accommodate the scaffolding plate 5.

[0024] Furthermore, as shown in Figures 1 to 3, a pivot shaft 6 may be provided on the front wall 1 of the base 4, or grooves 8 may be provided on the two side walls 3 near the rear wall 2, and the adjustment support column 9 may be fixed by fitting it into the grooves 8. In order to hold the adjustment support column 9 more firmly, fixing walls 10 may be provided on the front and back of the adjustment support column 9.

[0025] As shown in Figures 1 and 2, an internal side wall 28 may be provided on the inside of the side wall 3, and a reinforcing support column 27 may be inserted between the front and rear ends of the side wall 3 for the purpose of assisting the adjustment support column 9 within the base 4 and scaffolding plate 5, and fixing members may be provided at the front and rear to support the reinforcing support column 27.

[0026] In addition, sound-absorbing material or vibration-damping material 29 may be attached to the scaffolding plate 5, which is pivotally supported by the swing shaft 7 installed on the base 4, in order to reduce noise or prevent shaking.

[0027] <Embodiment 2> Next, the golf practice platform B according to Embodiment 2 of the present invention will be described using Figures 5 and 6. Figure 5 is an external perspective view of the golf practice platform B according to Embodiment 2 of the present invention, and Figure 6 is a right side view of the golf practice platform B according to Embodiment 2 of the present invention.

[0028] As shown in Figures 5 and 6, by providing an outer frame 30 on the upper surface of the outer circumference of the scaffolding plate 5 of the golf practice platform B and one or more detachable materials 31 on the upper surface of the scaffolding plate 5, it becomes possible to lay artificial turf or a mat that mimics the ground. By changing different types of artificial turf, various golf ball placement conditions can be simulated, and it is easy to replace the artificial turf with new turf when it wears out. In addition, to prevent the sound and vibration of golf club impacts, vibration-damping rubber or the like can be attached to the scaffolding plate 5, and the detachable material 30 can be attached on top of that, and the detachable material can be attached to the underside of the artificial turf, etc., and the artificial turf, etc. can be removed.

[0029] <Embodiment 3> Next, the golf practice table B according to Embodiment 3 of the present invention will be described with reference to Figures 7 to 9. Figure 7 is an enlarged right side view of the golf practice table B according to Embodiment 3 of the present invention, Figure 8 is an enlarged top view of the golf practice table B according to Embodiment 3 of the present invention, and Figure 9 is a perspective view showing the golf practice table B according to Embodiment 3 of the present invention disassembled.

[0030] The golf practice platform B of Embodiment 3 is a structure provided to strengthen the connection between the base 4 and the scaffolding plate 5. A U-shaped metal fitting 13 is attached to the end of the front wall 1 of the scaffolding plate 5, and metal fittings 14 with a first pivot shaft hole 61 at the tip are attached to both sides. Similarly, a U-shaped metal fitting 15 is attached to the end of the top of the front wall, and metal fittings 16 with a second pivot shaft hole 62 at the tip are attached to both sides, and the pivot shaft 7 may pass through the first pivot shaft hole 61 and the second pivot shaft hole 62. The material of the metal fittings 14 and 16 is not particularly specified, but since they are provided to strengthen the connection between the base 4 and the scaffolding plate 5, it is preferable that they be made of iron.

[0031] <Embodiment 4> Next, the golf practice platform B according to Embodiment 4 of the present invention will be described with reference to Figures 10 and 11. Figure 10 is a right side view of the golf practice platform B according to Embodiment 4 of the present invention and a front view of the adjustment support column 9, and Figure 11 is a plan view of the golf practice platform B according to Embodiment 4 of the present invention.

[0032] As shown in Figures 10 and 11, in Embodiment 4, the three types of adjustable support columns 9a, 9b, and 9c are U-shaped and have support column shaft holes 9h at both ends to support shaft penetration. The base 4 includes a support shaft 9p that connects the side walls, and a support wall 20 that supports the adjustable support columns 9a, 9b, and 9c so that they stand vertically. By passing the support shaft holes 9h of the adjustable support columns 9a, 9b, and 9c, which have different widths, through the support shaft 9p, multiple adjustable support columns 9a, 9b, and 9c are housed inside the base 4, and by standing one of the multiple adjustable support columns 9a, 9b, and 9c upright, the scaffolding plate 5 is held at a predetermined inclination angle as shown in Figure 10.

[0033] <Embodiment of Ball Set Plate 12> Next, the ball set plate 12 according to Embodiments 1 to 4 will be described with reference to Figures 12 and 13. Figure 12 is an enlarged plan view showing the structure of the ball set plate of the golf practice table B according to the present invention, and Figure 13 is a cross-sectional view showing the structure of the ball set plate 12 of the golf practice table B according to the present invention.

[0034] As described above, on a golf course, the ball is also on uneven ground, and because the slope of the footing and the slope of the ball's position are different, the height and distance between the footing and the ball vary depending on the footing. To reproduce this condition, the ball set plate 12 is equipped with an arm portion 24 that extends and retracts along the guide member 23. As shown in Figure 12, the distance between the golfer and the golf ball is adjusted by adjusting the distance between the footing plate 5 and the ball set plate 12 in the movement of step S1, and the ball set plate 12 is kept horizontal based on the angle of the footing plate in the movement of step S2.

[0035] Figure 13a) is a cross-sectional view of AA shown in Figure 12, and Figure 13b) is a cross-sectional view of BB shown in Figure 12. However, as shown in Figure 13b), instead of rotating the inclined ball set plate 12 in the direction of S2, a flexible joint 25 may be used to keep the tee portion 26 horizontal.
