Abstract

To meet almost all golfers' wishes of performing, at a golf practice range, shot practice on a slope like golf courses having many undulations where a ball shooting way depending on a footing state is required, practice for which is impossible in golf practice ranges having flat floors.SOLUTION: A golf practice apparatus can simulate footing states of raised toes, lowered toes, lowered left foot, and raised left foot in a golf course, by performing first axis control of rotating a footing plate 3 using a rotation frame 1 and second axis control of rotating the rotation frame 1 using a fixed frame 7. The golf practice apparatus also makes it possible to perform golf practice while setting a ball, by sliding a ball set plate 12 to a ball position using an arm 11 and moving a tee 13 so that the tee 13's top is horizontal, in order to cope with a distance and height difference between footing and the ball.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a golf practice device that is different from a golf practice range and has a foothold plate that can be changed three-dimensionally like a golf course, and a ball setter that corresponds to the foothold plate. [Background technology]

[0002] At golf driving ranges, practice is always done on a flat surface. However, on an actual golf course, the terrain is undulating, and shots tend to be missed due to unusual posture and deviation in the position of the center of gravity. For example, when standing on a toe-up platform, the center of gravity is shifted backwards and the player is forced to look up, resulting in hitting the ball below or above the ball and making a mistake. For this reason, there is a way to hit the ball depending on the footing conditions, but this cannot be practiced at a golf driving range. Therefore, most golfers would like to be able to practice shots on a slope at a driving range, just like on a golf course.

[0003] Generally, there are four typical footing conditions on a golf course: toe up, toe down, left foot down, and left foot up. There is a need for a golf practice device having a foothold plate that can simulate these four foothold conditions. Furthermore, on a golf course, the ball is on an undulating surface, and the slope of the footing and the slope of the ball's position differ, so the height and distance between the footing and the ball vary depending on the footing condition. For example, when the toe is up, the ball is higher than the footing, but the distance can be closer or farther depending on the slope of the ball's position. When the toe is down, the ball is lower and farther away. It is desirable for the golf practice device to be able to set the distance and height from the ball separately from the foothold plate.

[0004] A golf training device is proposed in Patent Document 1. This device comprises a main body (12) with artificial turf (12a) on the upper surface, a base (14) located below the main body and connected to the main body so that the main body can rotate at one side, and a tilting means for tilting the main body around one side, so that the base and the main body can be rotated.

[0005] Similarly, a golf practice device is proposed in Patent Document 2. This golf practice equipment is proposed in which the practice body is fixed with a universal joint, and a pressurizing compressor is connected to a programmed controller by hydraulic pressure, air pressure, etc. to change the scaffold body three-dimensionally. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2006-223515 [Patent Document 2] Utility model registration No. 3126699 Summary of the Invention [Problem to be solved by the invention]

[0007] Generally, when you swing at a ball, the ball will fly to the left of your standing position. At a golf driving range, the direction in which the ball will fly is fixed. In Patent Document 1, the main body that serves as the foothold plate is inclined in one direction, so you will need to change your standing position back and forth, left and right to simulate the four foothold conditions mentioned above. If you change your position, the direction the ball flies will also change. You will need to rotate and move the device to match the direction the ball flies at the driving range.

[0008] On an undulating golf course, the gradient of the footing and the gradient of the ground on which the ball is placed are often different. This means that the ball is positioned higher or lower than the footing. Also, players have no choice but to place their feet closer to the ball, or the footing is farther away. This is difficult to deal with using the method of placing the ball on a footing plate as in Patent Document 1.

[0009] After deciding where to stand, you set the ball to hit it, but the ball moves on the inclined platform. Even if you put artificial turf on the surface, the ball is unstable. Also, when practicing golf, you hit the artificial turf under the ball, but the artificial turf wears down and becomes slippery, and if there is an incline, the ball will roll off.

[0010] In the above-mentioned document 2, the practice body, which is a scaffold plate, is fixed and held on four or more axes, and the axes are pressurized with a hydraulic system or the like to control the position. This is a difficult multi-axis control for a flat plate. Moreover, the golf driving range will need new and expensive equipment such as a hydraulic system and an air compression compressor. Furthermore, a golf driving range will have many golf driving seats, and the hydraulic piping equipment, etc. will be large-scale.

[0011] In addition, because the ball is set on the platform plate, the distance between the platform and the ball and the height of the ball cannot be adjusted as described above, and there are still problems such as the ball rolling off.

[0012] The present invention has been made to solve the above problems, and proposes a golf practice device equipped with a foothold plate capable of simulating the four foothold conditions on a golf course, and a ball setter that can accommodate differences in distance and height between the foothold and the ball, and can prevent the ball from rolling off when set on a slope. [Means for solving the problem]

[0013] The invention described in claim 1 is The scaffolding device includes a fixed frame that is fixed to the ground or a floor surface, a rotating frame that is pivotally supported by the fixed frame and accommodated therein so as to be rotatable around an X-axis, and a scaffolding plate that is pivotally supported by the rotating frame and accommodated therein so as to be rotatable around a Y-axis, The rotating frame has a fixing means that is fixed to the fixed frame at a predetermined inclination angle, The foothold plate relates to a golf practice device having a fixing means fixed to the rotating frame at a predetermined inclination angle, and a ball setter that moves back and forth in the X direction and places a ball at a predetermined position in the X direction.

[0014] The invention described in claim 2 is The ball setter is a golf practice device characterized by having an arm that moves back and forth along a guide member attached to the footing plate, and a ball setting plate or cup that engages with the tip of the arm via a universal joint.

[0015] The invention described in claim 3 is This relates to the training device described in claim 1 or 2, characterized in that the fixing means has a locking hole or catcher provided in the rotating frame and a fixing pin protruding from the fixing frame that engages with either of them, and has a locking hole or catcher provided in the scaffold plate and a fixing pin protruding from the rotating frame that engages with either of them.

[0016] The invention described in claim 4 is The scaffolding device includes a fixed member that is fixed to the ground or floor surface, a rotating frame that is pivotally supported by the fixed member and arranged to be rotatable around the X-axis, and a scaffolding plate that is pivotally supported by the rotating frame and accommodated therein to be rotatable around the Y-axis, the rotating frame has a fixing means that is fixed to the fixed member at a predetermined inclination angle, The foothold plate relates to a golf practice device having a fixing means fixed to the rotating frame at a predetermined inclination angle, and a ball setter that moves back and forth in the X direction and places a ball at a predetermined position in the X direction.

[0017] The invention described in claim 5 is The scaffolding plate has a base that is fixed to the ground or floor surface, and is supported by a swing shaft that is held or fixed to the base and is held at a predetermined inclination angle. The foothold plate relates to a golf practice device having a ball setter that moves back and forth in the axial direction of the swing shaft and in a direction perpendicular to the axial direction, and places balls at predetermined positions in each of these directions.

[0018] The invention described in claim 6 is The present invention relates to a golf practice device as described in claim 5, characterized in that the foothold plate is held by a swing shaft and a height-adjustable support pillar standing on a base at a distance from the swing shaft.

[0019] The invention described in claim 7 is The scaffold plate has an inclined arm that rotatably hangs down from the back surface or side surface of the scaffold plate, and the base has a plurality of retaining holes or retaining stoppers that engage with the tip ends of the inclined arms, The golf practice device according to claim 5, characterized in that the inclination arm is engaged with a predetermined one of the plurality of retaining holes or retaining stoppers in accordance with the set inclination angle of the foothold plate.

[0020] The invention described in claim 8 is This relates to a golf practice device having a foothold plate that is held at a predetermined inclination angle around the Y axis and the X axis of a base fixed to the ground or floor, and a ball setter that moves forward and backward in the X direction from the foothold plate to place a ball at a predetermined position in the X direction. Effect of the Invention

[0021] The effects of the invention according to claims 1 to 4 will be explained. The first axis control is when the scaffold plate is supported by a rotating frame and rotates around the Y axis. The second axis control is when the rotating frame is supported by a fixed frame and rotates around the X axis. By controlling the first and second axes, the four typical foothold conditions on a golf course can be simulated using a foothold plate. By determining the standing position in the X direction and controlling the first axis, the foothold plate will tilt back and forth, simulating toe-up and toe-down foothold conditions. If the second axis is controlled with the scaffold plate kept horizontal without changing the standing position, the scaffold plate will tilt left and right, simulating the left foot down and left foot up scaffolding conditions. Furthermore, by combining first-axis control and second-axis control, complex footing conditions such as toes up and left foot down can be easily simulated.

[0022] The pivot frame has fastening means for fastening to the fixed frame at a predetermined inclination angle, and the scaffold plate has fastening means for fastening to the pivot frame at a predetermined inclination angle. By rotating the X-axis and Y-axis about the center of each side, it is easy to balance the forces around the axes and the rotation can be easily performed by manual operation. Therefore, the axis is manually rotated to a predetermined inclination angle and fixed by the fixing means.

[0023] In addition, as a fixing means, it has a fixing pin protruding from the fixing frame which engages with either an engagement hole or a catcher provided in the rotating frame, and it has a fixing pin protruding from the rotating frame which engages with either an engagement hole or a catcher provided in the scaffold plate, and the scaffold plate can be fixed in a predetermined position by manually inserting and removing the fixing pin. No new equipment such as a hydraulic system or air compressor is required to rotate and fix the rotating frame and scaffolding plate, and the system is compact, lightweight, and inexpensive, making it easy to introduce at golf driving ranges.

[0024] On an undulating golf course, the slope of the footing and the slope of the ball are often different. This means that the ball is higher or lower than the footing. The distance between the footing and the ball also varies, with players being forced to place their feet closer to the ball and others being further away.

[0025] The ball setter positions a ball setting plate for setting balls at a predetermined position by an arm that moves back and forth along a guide member. The distance and height between the foot position and the ball position can be changed freely.

[0026] The size of the scaffold plate needs to be about 80 cm square for the swing action considering the foot width and ball placement, but by providing a separate ball setting plate for setting the ball, the size of the scaffold plate can be reduced to about 70 cm square, making it compact and reducing the cost of the golf practice equipment and making it easier to transport and handle.

[0027] The arms and ball setting plates attached to the inclined scaffolding plates are also inclined, so once the ball is placed on it, it will not stop moving. The tip of the arm has a ball setting plate or cup that engages via a universal joint, and the balls can be set stably by aligning the ball setting plate or cup horizontally.

[0028] Claims 1 to 4 make it possible to provide a golf practice device that includes a downsized platform plate that can simulate the four platform conditions on a golf course, and a ball setter that can accommodate differences in distance and height between the platform and the ball and prevent the ball from rolling when set on a slope.

[0029] The effects of the invention according to claims 5 to 7 will be explained. Golf lovers and avid golfers not only practice at driving ranges, but also at home by practicing their swings or hitting plastic balls. There is a demand for a golf practice device that can simulate the four foothold conditions of a golf course and a ball setter, so that practice can be done not only at a golf driving range but also at home.

[0030] In claim 6, the height of the scaffold plate is adjusted and held / fixed by a height-adjustable support. It has a simple configuration like a seesaw in a park, and has a simple structure that combines height adjustment and fixing.

[0031] In claim 7, the scaffold plate is held and rotated, and the tilt arm that rotatably hangs down from the back or side of the scaffold plate is engaged with the holding hole or holding stopper of the base according to the set tilt angle. The scaffold plate can be easily fixed and held at the set tilt angle by holding it. In addition, the base, scaffold plate, and tilt arm can be folded and stored as a single unit, making it easy to transport and handle.

[0032] According to the invention of claims 5 to 7, the device is a simple and compact golf practice device equipped with a ball setter and a platform plate that can simulate four platform conditions, and can be installed at home. In addition, the size of the platform plate can be reduced to about 70 cm square by providing a separate ball set plate for setting the ball.

[0033] However, these devices rotate in one direction using a swing axis, and in order to simulate the four foot positions mentioned above, it is necessary to change the standing position back and forth and left and right. In addition, since the direction in which the ball is hit changes depending on the standing position, if the ball's hitting direction is restricted, it is necessary to rotate and move the golf training device.

[0034] In claim 8, The scaffold plate is held and fixed at a specified inclination angle around the Y-axis and X-axis. The four scaffold conditions mentioned above can be simulated without changing the standing position. [Brief description of the drawings]

[0036] Hereinafter, each embodiment of the present invention will be described with reference to simple drawings of a golf training device. In each drawing, the same or corresponding parts and components are denoted by the same reference numerals. In addition, when the inclination angle of the scaffold plate 3 was changed in the prototype, it was found that an inclination angle of up to 15 degrees was safe, but any steeper angle than that was dangerous. Since an inclination angle of up to 15 degrees is a reasonable inclination angle, the specified inclination angles are set to 5 degrees, 10 degrees, and 15 degrees. The above three inclination angles allow for simulation of practice on sloping ground ranging from easy to difficult.

[0037] 1 to 3 show an example of an embodiment of the invention described in claim 1, claim 2, and claim 3. In Fig. 1, a rotating frame rotating shaft 2 is provided at the center of the side of a rotating frame 1 of a golf training device, and a scaffold plate 3 is held by the rotating frame 1 by engaging with the rotating frame rotating shaft 2. The scaffold plate 3 has a hole shown by a dashed line into which the rotating frame rotating shaft 2 fits, so that the scaffold plate 3 can rotate around the rotating frame rotating shaft 2 as the rotating shaft. A part of the scaffold plate is cut out to accommodate a ball set plate 12.

[0038] In FIG. 2, first inclination adjustment holes 4 are provided on the left and right sides of the rotating frame 1. When the scaffold plate 3 shown by the dashed line is fixed to the first inclination adjustment hole 4 on the left side, the toes are down, and when it is fixed to the first inclination adjustment hole 4 on the right side, the toes are up. The scaffold plate 3 shown by the dashed line has a first locking hole 5 also shown by the dashed line. When the handle 17 shown by the dashed line is grasped and rotated, and the first locking hole 5 is aligned with any of the first inclination adjustment holes 4 and the fixing pin 18 shown in Fig. 4 is inserted, the scaffold plate 3 is fixed and held to the rotating frame 1, and the scaffold is placed in a toe-down or toe-up position.

[0039] Figures 4 to 7 show an example of an embodiment of the invention recited in claim 3. Figure 4 shows the positional correlation between the first locking hole 5 and the first inclination adjustment hole 4 in Figure 2. The first inclination adjustment hole 4 is disposed in correspondence with the rotation orbit of the first locking hole 5. A first locking hole 5 provided in the scaffold plate 3 rotates by a rotating frame rotating shaft 2 provided in the rotating frame 1, and rotates from point A on the track to point B where the first tilt adjustment hole 4 on the track is located.

[0040] FIG. 5 is an explanatory cross-sectional view taken at point A in FIG. The first locking hole 5 is provided with a catcher 19. The catcher 19 pushes the rotating object in the direction of rotation. FIG. 6 is an explanatory cross-sectional view taken at point B in FIG. A lock fitting 20 incorporating a fixing pin 18 is attached to the first inclination adjustment hole 4 of the rotating frame 1. When the desired inclination, such as toe-up, is this first inclination adjustment hole 4 , the fixing pin 18 is pushed toward the scaffold plate 3 . The pushing distance is approximately the distance between the rotating frame 1 and the scaffold plate 3. FIG. 7 is a diagram showing the first locking hole 5 rotated to point B. When the catcher 19 rotates toward point B, it comes into contact with the fixed pin 18 and stops rotating. Since the first locking hole 5 and the first tilt adjustment hole 4 are aligned, the fixed pin 18 of the locking metal fitting 20 is pushed into the first fixing hole 5 to fix and hold the scaffold plate 3 to the rotating frame 1.

[0041] Since a plurality of first inclination adjustment holes 4 can be set, holes corresponding to 5 degrees, 10 degrees, and 15 degrees can be set, so that footing conditions ranging from gentle to steep inclinations can be simulated.

[0042] As shown in Figure 1, both feet are placed forward on the virtual footing position 6 of the footing plate 3. By aligning any one of the left and right first inclination adjustment holes 4 in Figure 2 with the first locking hole 5 and inserting the fixing pin 18 of the locking metal fitting 20 of the first inclination adjustment hole 4, it is possible to simulate toe-up and toe-down footing states without changing the standing position.

[0043] 1, fixed frame rotation shafts 8 are provided in the center of the front and rear sides of fixed frame 7, and rotating frame 1 is engaged with fixed frame rotation shafts 8 and held by fixed frame 7. Rotating frame 1 has a hole into which fixed frame rotation shaft 8 fits, so that rotating frame 1 can rotate around fixed frame rotation shaft 8.

[0044] In FIG. 3, second tilt adjustment holes 9 are provided on the left and right sides of the fixed frame 7. When the rotating frame 1 is fixed at the second inclination adjustment hole 9 on the left side, the left foot is raised, and when it is fixed at the second inclination adjustment hole 9 on the right side, the left foot is lowered. There are second locking holes 10, indicated by dashed lines, on the left and right sides of the rotating frame 1. When either the left or right second locking hole 10 is aligned with the corresponding left or right second inclination adjustment hole 9 and a fixing pin is inserted, the rotating frame 1 is fixed and held by the fixed frame 7, creating a left foot up or left foot down foothold state.

[0045] The positional correlation diagram, rotation, and fixing / holding method of the second locking hole 10 and the second inclination adjustment hole 9 are the same as those of the first locking hole 5 and the first inclination adjustment hole 4 shown in Figures 4, 5, 6, and 7. In the case of a second locking hole 10 and a second tilt adjustment hole 9 arranged to correspond to the rotation orbit of the second locking hole 10, in Figures 4 to 7, the rotating frame 1 is the fixed frame 7, the scaffolding plate 3 is the rotating frame 1, the rotating frame rotation axis 2 is the fixed frame rotation axis 8, the first locking hole 5 is the second locking hole 10, and the first tilt adjustment hole 4 is the second tilt adjustment hole 9. In addition, since multiple second inclination adjustment holes 9 can be set, by setting holes corresponding to 5 degrees, 10 degrees, and 15 degrees, it is possible to simulate footing conditions ranging from gentle to steep.

[0046] As shown in Figure 1, the user places both feet on the virtual footing position 6 of the footing plate 3 facing forward. By aligning any of the second locking holes 10 in Figure 3 with the corresponding second inclination adjustment hole 9 and inserting a fixing pin, footing conditions such as left foot up or left foot down can be simulated without changing the standing position.

[0047] As described above, toe up, toe down, left foot up, and left foot down can be simulated without changing the standing position on the footing plate. Even if the footing state changes, the ball's flight direction remains the same, making it easy to introduce into golf driving ranges where the flight direction is fixed. In the case of toe down, it is also possible to store the ball in the ball set plate 12 in the cutout of the footing plate 3 as shown in Figure 1, and place the ball on a floor mat or the like to hit it.

[0048] As shown in Figures 1, 2, and 3, The ball setter is composed of an arm 11 that moves back and forth along a guide member 14 provided on the footing plate 3, and a ball setting plate 12 as a ball placement portion that engages with the tip of the arm via a universal joint. The ball setting plate 12 is provided with a tee 13 made of rubber or the like for setting a ball, and the ball is placed on the tee and hit.

[0049] As described above, when simulating a toe-up footing state, for example, the player places both feet on the virtual footing position 6 of the footing plate 3 that is inclined high forward, and sets the ball on the tee 13. On the golf course, when standing on tiptoes, the ball is positioned relatively close to and higher than the platform. To simulate a golf course, the arm 11 is advanced and retreated to place the ball setting plate 12 at a desired position.

[0050] 2 and 3, guide members 14 are attached in two parallel rows to the underside of the scaffold plate 3, and arms 11 are housed in the guide members 14. The arm 11 slides along a guide member 14, and can move the ball set plate 12 forward and backward to any desired position.

[0051] The size of the foothold plate 3 must be about 80 cm square, taking into consideration the width of the feet and the condition of the foothold, in order to place the ball on the foothold plate 3 and perform a swing motion. By providing a ball setting plate 12 for setting balls separately from the scaffold plate 3, the size of the scaffold plate can be reduced to about 70 cm square, and the compact size reduces the cost of the golf practice device and makes it easier to transport and handle.

[0052] Hold the ball setting plate 12 with your hand and slide the arm 11 to set it in the desired position. The ball is placed on the top of the tee 13, but since the top of the tee 13 is not horizontal in an inclined position, the ball may roll off when placed on it.

[0053] As shown in Figure 3, a universal joint 16 is fitted inside the tee 13. Since the universal joint 16 moves three-dimensionally, the tee 13 is moved so that the top is horizontal, and a ball is placed on it. The universal joint 16 has a flange and is fitted into the ball set plate 12, so that the tee 13 will not come off even when subjected to the impact of hitting the ball.

[0054] FIG. 8 is an explanatory diagram for adjusting the position and height of the ball set plate 12. On an undulating golf course, the gradient of the foothold and the gradient of the ground on which the ball is placed often differ, and the distance and height between the foothold and the ball often vary. After the arm 11 is slid to the expected position where the ball is located, the rotation pin 15 is rotated to adjust the height of the ball setting plate 12.

[0055] As described above, the first axis is controlled to rotate the scaffold plate 3 by the rotating frame 1. Second axis control for rotating the rotating frame 1 by the fixed frame 7. This allows the four footing conditions mentioned above on a golf course to be simulated. In addition, by simultaneously combining the first axis control and the second axis control, it is possible to simulate complex footing conditions such as toe up with the left foot up and toe up with the left foot down, which are difficult to simulate in the above-mentioned Patent Document 2. In either case, the ball setting plate 12 is slid to the ball position by the arm 11, the height is adjusted by the rotating pin 15, and the tee 13 is moved so that the top of the tee 13 is horizontal, and the ball is set. This golf practice device allows golf practice while setting a ball on a downsized footing plate 3 simulating various footing conditions on a golf course and a ball setting plate 12 corresponding to the downsized footing plate.

[0056] 9 to 12 show an example of an embodiment of the invention as defined in claim 4. FIG. This is an embodiment in which the fixing frames of the embodiments according to claims 1, 2, and 3 shown in Figs. 1 to 8 are used as fixing members. There are fixed members A29 and B30 that are fixed to the ground or floor surface, and a rotating frame 1 that is supported by the fixed members and arranged to be rotatable around the X-axis, but the other configurations and movements are the same. In Figs. 9 and 10, The scaffold plate 3 is supported by the rotating frame 1 and accommodated so as to be rotatable around the Y axis. The scaffold plate 3 has a fixing means for fixing the rotating frame 1 at a predetermined inclination angle, an arm 11 that advances and retreats in the X direction along a guide member 14 provided on the scaffold plate 3 to place a ball at a predetermined position in the X direction, and a ball set plate 12 that engages with the tip of the arm via a universal joint. The configuration and movement of the scaffold plate 3 are the same as those of the embodiments of the form of carrying out the invention described in claim 1, claim 2, and claim 3.

[0057] In FIG. A fixed member A 29 and a fixed member B 30 fixed to the ground or floor surface support the rotating frame 1 by a fixed member A rotating shaft 31 and a fixed member B rotating shaft 32, and rotate the rotating frame 1 around the X-axis.

[0058] FIG. 11 is a front view of the fixing member A29. FIG. 12 is an explanatory diagram of a side view in the direction A at A in FIG. On the left and right sides of the rotating frame 1, there are second locking holes 10 indicated by dashed lines. The second locking hole 10 is provided with a catcher 19. The catcher 19 pushes the rotating object in the direction of the rotation. Fixed member inclination adjustment holes 37 corresponding to the rotation trajectory of the second engagement hole 10 are arranged on the left and right sides of the fixed member B30, and a locking fitting 20 is provided in the fixed member inclination adjustment hole 37, and a fixed pin 18 is inserted into the fixed member inclination adjustment hole 37. The fixed pin 18 protrudes approximately to the distance between the rotating frame 1 and the fixed member B30.

[0059] When the catcher 19 rotates, it comes into contact with the fixed pin 18 and stops rotating. Since the second locking hole 10 and the fixed member inclination adjustment hole 37 are aligned, the fixing pin 18 of the lock metal fitting 20 is pushed into the second locking hole 10 to fix and hold the rotating frame 1 to the fixed member B30. When the rotating frame 1 is fixed at the left fixing member inclination adjustment hole 37, the left foot is lowered, and when the rotating frame 1 is fixed at the right fixing member inclination adjustment hole 37, the left foot is raised. When either the left or right second locking hole 10 is aligned with the fixing material inclination adjustment hole 37 into which the corresponding fixing pin 18 is inserted and the fixing pin 18 is pushed into the second locking hole 10, the rotating frame 1 is fixed and held by the fixing member A 29 and the fixing member B 30, creating a left foot up or left foot down foothold state.

[0060] In FIG. 9, the method of fixing the scaffold plate 3, which is supported by the rotating frame 1 and housed therein so as to be rotatable around the Y axis, to the rotating frame at a predetermined inclination angle by the first inclination adjustment hole 4 and the first locking hole 5, and the configuration, movement, effect, etc. of the arm 11 and ball set plate 12, which move forward and backward in the X direction and place the ball at a predetermined position in the X direction, etc., are similar to those of the embodiments of claim 1, claim 2 and claim 3.

[0061] This golf practice device allows golf practice while setting a ball on a foothold plate 3 simulating various foothold conditions on a golf course and a ball setting plate 12 corresponding to the foothold condition. As shown in Figs. 11 and 12, anchors 33 are provided under the fixing members A29 and B30 to prevent them from falling over.

[0062] FIG. 13 shows an example of an embodiment of the invention described in claims 5 and 6. In FIG. FIG. 14 is an explanatory diagram of a plane in the direction B at B in FIG. The scaffold plate 3 is held by a swing shaft 26 and a height-adjustable support 28 standing on the base 23 at a distance from the swing shaft 26. The locking fitting 20 is provided on the height adjustment support 28 so as to correspond to the rotational trajectory of the locking hole 27 shown by the dashed line when the scaffold plate 3 is held and rotated by the swing shaft 26. Hold the scaffold plate 3 and rotate it using the swing shaft 26 to align the locking hole 27 shown by the dashed line on the scaffold plate 3 with the locking fitting 20 on the height-adjustable support 28 that corresponds to the desired inclination angle, and push the fixing pin 18 provided on the locking fitting 20 into the locking hole 27 to fix and hold the scaffold plate 3 to the height-adjustable support 28.
