And guides the cup-in golf ball B downward, and guides the golf ball B dropped downward from the communication opening 10 of the base member 9 into the guide hole 28 ( A rail-shaped guide member 29 for guiding (see FIG. 7) is attached to the above-mentioned bottom plate 6.

A mechanism for supplying the golf ball B guided to a predetermined portion of the bottom plate 6 from the guide hole 28 on the lower side of the hole with the stance position S of the artificial grass 2 (see FIG. 1) is shown in FIG. It is configured as shown in FIGS. That is, a standing wall 31 is attached at a lateral position between the above-mentioned bottom plate 6 and the top plate 30 on which the artificial grass 2 is laid, and the standing wall 31 is used to make One conveyor 32 (see FIG. 7) and a second conveyor 33 (see FIG. 8 and FIG. 9) on the side of the stance position S are arranged, and a guide means is provided between these conveyors 32, 33. The guide rail 34 is stretched.

As shown in FIG. 7, the above-described first conveyor 32 has the golf ball B guided to the lower side of the hole portion from the above-described outlet hole 28 within the height range of the machine casing 1 on the side portion of the hole portion. The first conveyor 32 is an endless belt 38 stretched around a plurality of rollers 35, 36 and 37, and the endless belt 38 is lifted up from the lower side to the upper side. The plurality of attached dogs 39 having flexibility, and the cover member 40 that covers the required positions of the loci of these dogs 39 are provided, and the golf ball B led out from the lead-out hole 28 is driven in the direction of the arrow in FIG. After being lifted up from the lower side to the upper side by the dog 39 as shown by the phantom line in FIG. 7, the balls are discharged from the ball delivery section 41 to the upper surface of the guide rail 34.

The above-mentioned second conveyor 33 is a conveyor that lifts up the golf ball B from its lower side to its upper side at the side of the stance position S as shown in FIGS. 8 and 9. The conveyor 33 includes an endless belt 44 stretched around a plurality of rollers 42, 43, a plurality of flexible dogs 45 attached to the endless belt 44 at predetermined equal intervals, and a required locus of each dog 45. The cover 45 is provided with a cover member 46 for covering, and the golf ball B received from the lower end of the guide rail 34 by the ball receiving portion 47 of the second conveyor 33 is driven by the dog 45 in the arrow direction of FIG. After being lifted up from the lower side to the upper side as shown, it is discharged from the gutter-shaped ball outlet member 48 shown in FIG. 9 to the upper surface of the artificial grass 2 on the stance position S side.

In this embodiment, the lower part of the ball outlet member 48 is fixed to the standing wall 31, and the roller shaft of the upper roller 42 of the second conveyor 33 is rotatable between the ball outlet member 48 and the cover member 46. The roller shaft of the roller 43 on the lower side of the second conveyor 33 is interlocked with the drive motor 49. A regulation rubber member 50 that guides the golf ball B toward the ball outlet member 48 is attached to the inner surface of the cover member 46 facing the upper portion of the second conveyor 33, if necessary.

The guide rail 34, which is stretched between the first conveyor 32 and the second conveyor 33 described above, has a ball sending section 41 in the first conveyor 32 and a ball receiving section 47 in the second conveyor 33. It is a guide means for extending the golf ball B on the upper surface of the guide rail 34 in an inclined manner between the guide rail 34, and the inclination angle θ of the guide rail 34 is set to about 5 degrees. Here, the above golf ball B is prevented from flowing down to the upper side in FIGS. 7 and 8 by the cover member constituting the outer wall of the machine frame 1, but the guide rail 34 described above has a trough with a concave cross section as necessary. It may be configured in a shape.

By the way, as shown in FIG. 1, a first sensor 51 for detecting the passage of the golf ball B is provided at a portion slightly offset from the stance position S to the hole position H side. As shown in FIG. 2, a second sensor 52 for detecting the cup-in of the golf ball B is provided in the lower portion of the hole 3 (specifically, the lower hole edge of the communication opening 10 in the base member 9). Each of these sensors 51, 52 is composed of a photoelectric sensor or the like having a light emitting element and a light receiving element.

FIG. 10 shows a control circuit of the putting practice machine, and the CPU 60 drives the score display section 54 and the prize discharge section 55 according to the program stored in the ROM 53 based on the signals from the above-mentioned sensors 51 and 52. The RAM 56 stores the necessary data. In FIG. 1, reference numeral 57 denotes an artificial turf having a large turf which is laid in a U shape in a plan view in the peripheral portion of the hole position H. Further, an adjusting screw (not shown) may be attached to the lower surface of at least the four corners of the machine frame 1 shown in FIG. 1 to adjust the height and tilt angle of the entire putting training machine.

The operation of the putting practice machine configured as described above will be described in detail below with reference to the flow chart shown in FIG. When the player puts the golf ball B at the stance position S, the CPU 60 executes the signal reading from the sensors 51 and 52 in the first step S1, and the CPU 60 turns the first sensor 51 ON in the next second step S2. It is determined whether or not, and only when YES is determined, the process proceeds to the next third step S3.

In this third step S3, the CPU 60 starts timer counting by its built-in timer. Next, in a fourth step S4, the CPU 60 determines whether or not the second sensor 52 has turned to be due to the golf ball B being cup-in, and proceeds to the next fifth step S5 only when the YES determination is made.

In the fifth step S5, the CPU 60 determines whether or not the cup-in is performed within a predetermined time. When the NO determination is made, the sixth step S6 is skipped to end the series of processes, while when the YES determination is made, the next step is performed. The process moves to sixth step S6. In this sixth step S6, the CPU 60 drives the prize discharging unit 55 to discharge the losing ball, and also drives the score display unit 54 to execute the prize processing such as visually displaying the putting score. After that, a series of processing is ended.

By the way, when the reversible motor 14 shown in FIG. 3 is driven, the circular motion of the rotational speed rotating body (see the worm wheel 12) is horizontally generated in the lower part of the artificial turf 2 in which the hole 3 is formed. It is converted into a vertical motion by 22. Then, the artificial turf 2 can be undulated in various ways through the plurality of thin plates 23 for undulation formation by the converted vertical momentum.

As a result, various undulations U as shown in FIG. 2 can be easily formed around the hole 3 of the artificial turf 2 and the rotation position of the above-mentioned rotating body (see the worm wheel 12) can be changed. The effect is that the undulation form can be changed arbitrarily. In addition, the structure for obtaining undulation is simple and inexpensive, and simplification of the structure has the effect of preventing the occurrence of failure.

Further, since the plurality of thin plates 23 for undulation formation and the rotating body (see the worm wheel 12) described above are formed with the communication openings 24 communicating with the holes 3 of the artificial turf 2, The golf ball B cup-in in the hole 3 can be guided downward through the hole 3 and the above-mentioned communication opening 24.

In addition, when the rotating body (see the worm wheel 12) driven by the driving means (see the worm 13) rotates in the horizontal direction, the rotary body (see the worm wheel 12) moves up and down in the through hole 16. The movably arranged slider 17 is vertically movable by the cam member 21, so that the circular motion of the rotating body (see the worm wheel 12) can be surely converted into the vertical motion. There is an effect that undulations of various and arbitrary shapes corresponding to the shape of the cam member 21 can be surely formed around the hole 3 of the grass 2.

Further, since the driving means (see the worm 13) and the rotating body (see the worm wheel 12) are specified as described above, the rotating body (see the worm wheel 12) is connected via the driving means (see the worm 13). It is possible to secure a sufficient torque necessary to drive the rotating body (see worm wheel 12) while reducing the size and power consumption of the driving source (see the reversible motor 14) to be driven. There is an effect that can be done.

In this embodiment, the driving means and the rotating body are exemplified as a combination of the worm 13 and the worm wheel 12, but a combination of a small diameter gear and a large diameter gear, a combination of a small diameter sprocket and a large diameter sprocket, and a small diameter gear. Even if the pulley and the large-diameter pulley are combined, the same action and effect are obtained.

Further, since the locus of the through hole 16 formed in the rotating body (see the worm wheel 12) and the periphery of the hole 3 of the artificial turf 2 described above are associated with each other in the vertical direction, the rotating body (see the worm wheel 12) An arbitrary undulation can be formed around the hole 3 by the slider 17 corresponding to the position change of the through hole 16 due to the rotation, and the position of the through hole 16 (the position of the slider 17) follows the locus. The effect is that the undulation form can be changed each time it changes.

Further, since the plurality of cuts 25 as described above are formed in the plurality of thin plates 23 for forming undulations, when the thin plate 23 is displaced in the vertical direction by the movement direction conversion means 22, the plurality of cuts 25 described above are formed. This has the effect of preventing distortion of the thin plate 23 and improving the durability of the thin plate 23. Furthermore, since the outer peripheral portions of the plurality of thin plates 23 for forming the undulations are held in a displaceable manner, the movement direction conversion means 22 allows the upper and lower displacements of the plurality of thin plates 23 to be performed more smoothly. At the same time, the distortion of the plurality of thin plates 23 can be reliably served.

Moreover, when the golf ball B led to the lower side of the hole is supplied to the stance position S of the artificial turf 2, the golf ball B on the side of the hole is moved to the lower side of the lower part by the first conveyor 32. The golf ball B is slightly accelerated by the first conveyor 32, and then the golf ball B is inclined from the ball delivery section 41 on the upper part of the first conveyor 32. It rolls on the upper surface of the means (see the guide rail 34) and is supplied to the ball receiving portion 47 of the second conveyor 33 at the position corresponding to the stance. Next, the golf ball B of the ball receiving portion 47 is re-lifted upward from the lower part of the second conveyor 33, and corresponds to the stance position S of the ball sending-out part (see the disposition part of the ball outlet member 48) of this upper part. It is transported to the part where

In this way, the golf ball B slightly accelerated by the first conveyor 32 rolls on the upper surface of the inclined guide means (see the guide rail 34), so that the rolling resistance due to the material of the golf ball B and the dimples is increased. Even so, the above-mentioned guide means (see the guide rail 34) can be supplied from the lower side of the hole portion to the portion corresponding to the stance position S at a slight inclination angle θ of, for example, about 5 degrees. As a result, there is an effect that the overall height of the training machine frame (see the machine frame 1) can be reduced and the apparatus can be made compact.

Is displaced in the left-right direction in FIG. Holds possible. That is, these thin plates 23 are not fixedly held, but are held displaceably in the above-mentioned slide space β.

Further, the hole 3 of the artificial turf 2, the communication opening 24 of the undulation-forming thin plate 23, the hole 11a of the cylinder shaft 11, and the communication opening 10 of the base member 9 are vertically aligned in this order. And guides the cup-in golf ball B downward, and guides the golf ball B dropped downward from the communication opening 10 of the base member 9 into the guide hole 28 ( A rail-shaped guide member 29 for guiding (see FIG. 7) is attached to the above-mentioned bottom plate 6.

It is configured as shown in FIGS. That is, a standing wall 31 is attached at a lateral position between the above-mentioned bottom plate 6 and the top plate 30 on which the artificial grass 2 is laid, and the standing wall 31 is used to make One conveyor 32 (see FIG. 7) and a second conveyor 33 (see FIG. 8 and FIG. 9) on the side of the stance position S are arranged, and a guide means is provided between these conveyors 32, 33. The guide rail 34 is stretched.

As shown in FIG. 7, the first conveyor 32 described above has the golf ball B drawn out from the above-mentioned exit hole 28 to the lower side of the hole portion within the height range of the machine casing 1 on the side of the hole portion. The first conveyor 32 is an endless belt 38 stretched around a plurality of rollers 35, 36 and 37, and the endless belt 38 is lifted up from the lower side to the upper side. The plurality of attached dogs 39 having flexibility, and the cover member 40 that covers the required positions of the loci of these dogs 39 are provided, and the golf ball B led out from the lead-out hole 28 is driven in the direction of the arrow in FIG. After being lifted up from the lower side to the upper side by the dog 39 as shown by the phantom line in FIG. 7, the balls are discharged from the ball delivery section 41 to the upper surface of the guide rail 34.

The above-mentioned second conveyor 33 is a conveyor that lifts up the golf ball B from its lower side to its upper side at the side of the stance position S as shown in FIGS. 8 and 9. The conveyor 33 includes an endless belt 44 stretched around a plurality of rollers 42, 43, a plurality of flexible dogs 45 attached to the endless belt 44 at predetermined equal intervals, and a necessary portion of the locus of each dog 45. The cover 45 is provided with a cover member 46 for covering, and the golf ball B received from the lower end of the guide rail 34 by the ball receiving portion 47 of the second conveyor 33 is driven by the dog 45 in the arrow direction of FIG. After being lifted up from the lower side to the upper side as shown, it is discharged from the gutter-shaped ball outlet member 48 shown in FIG. 9 to the upper surface of the artificial grass 2 on the stance position S side.

In this embodiment, the lower portion of the ball outlet member 48 is fixed to the standing wall 31, and the roller shaft of the upper roller 42 of the second conveyor 33 is rotatable between the ball outlet member 48 and the cover member 46. The roller shaft of the roller 43 on the lower side of the second conveyor 33 is interlocked with the drive motor 49. A regulation rubber member 50 that guides the golf ball B toward the ball outlet member 48 is attached to the inner surface of the cover member 46 facing the upper portion of the second conveyor 33, if necessary.

The guide rail 34, which is stretched between the first conveyor 32 and the second conveyor 33 described above, has a ball sending portion 41 in the first conveyor 32 and a ball receiving portion 47 in the second conveyor 33. It is a guide means for extending the golf ball B on the upper surface of the guide rail 34 in an inclined manner between the guide rail 34, and the inclination angle θ of the guide rail 34 is set to about 5 degrees. Here, the above golf ball B is prevented from flowing down to the upper side in FIGS. 7 and 8 by the cover member constituting the outer wall of the machine frame 1, but the guide rail 34 described above has a trough with a concave cross section as necessary. It may be configured in a shape.

By the way, as shown in FIG. 1, a first sensor 51 for detecting passage of the golf ball B is provided at a portion slightly offset from the stance position S to the hole position H side. As shown in FIG. 2, a second sensor 52 for detecting the cup-in of the golf ball B is provided in the lower portion of the hole 3 (specifically, the lower hole edge of the communication opening 10 in the base member 9). Each of these sensors 51, 52 is composed of a photoelectric sensor or the like having a light emitting element and a light receiving element.

FIG. 10 shows a control circuit of the putting practice machine, and the CPU 60 drives the score display section 54 and the prize discharging section 55 in accordance with the program stored in the ROM 53 based on the signals from the above-mentioned sensors 51 and 52. The RAM 56 stores the necessary data. In FIG. 1, reference numeral 57 denotes an artificial turf having a large turf which is laid in a U shape in a plan view in the peripheral portion of the hole position H. Further, an adjusting screw (not shown) may be attached to the lower surface of at least the four corners of the machine frame 1 shown in FIG. 1 to adjust the height and tilt angle of the entire putting training machine.

The operation of the putting practice machine configured as described above will be described in detail below with reference to the flow chart shown in FIG. When the player puts the golf ball B at the stance position S, the CPU 60 executes the signal reading from the sensors 51 and 52 in the first step S1, and the CPU 60 turns the first sensor 51 ON in the next second step S2. It is determined whether or not, and only when YES is determined, the process proceeds to the next third step S3.

In this third step S3, the CPU 60 starts timer counting by its built-in timer. Next, in a fourth step S4, the CPU 60 determines whether or not the second sensor 52 has turned to be due to the golf ball B being cup-in, and proceeds to the next fifth step S5 only when the YES determination is made.

In the fifth step S5, the CPU 60 determines whether or not the cup-in is performed within a predetermined time. When the NO determination is made, the sixth step S6 is skipped to end the series of processes, while when the YES determination is made, the next step is performed. The process moves to sixth step S6. In this sixth step S6, the CPU 60 drives the prize discharging unit 55 to discharge the losing ball, and also drives the score display unit 54 to execute the prize processing such as visually displaying the putting score. After that, a series of processing is ended.

By the way, when the reversible motor 14 shown in FIG. 3 is driven, the circular motion of the rotational speed rotating body (see the worm wheel 12) is horizontally generated in the lower part of the man-made grass 2 in which the hole 3 is formed. It is converted into a vertical motion by 22. Then, the artificial turf 2 can be undulated in various ways through the plurality of thin plates 23 for undulation formation by the converted vertical momentum.

As a result, various undulations U as shown in FIG. 2 can be easily formed around the hole 3 of the artificial turf 2 and the rotational position of the above-mentioned rotating body (see the worm wheel 12) can be changed. The effect is that the undulation form can be changed arbitrarily. In addition, the structure for obtaining undulation is simple and inexpensive, and simplification of the structure has the effect of preventing the occurrence of failure.

Further, since the plurality of thin plates 23 for forming the undulation and the above-mentioned rotating body (see the worm wheel 12) are formed with the communication openings 24 communicating with the holes 3 of the artificial grass 2, The golf ball B cup-in in the hole 3 can be guided downward through the hole 3 and the above-mentioned communication opening 24.

In addition, when the rotating body (see the worm wheel 12) driven by the driving means (see the worm 13) rotates in the horizontal direction, the rotary body (see the worm wheel 12) moves up and down. The movably arranged slider 17 is vertically movable by the cam member 21, so that the circular motion of the rotating body (see the worm wheel 12) can be surely converted into the vertical motion. There is an effect that undulations of various and arbitrary shapes corresponding to the shape of the cam member 21 can be surely formed around the hole 3 of the grass 2.

Since the driving means (see the worm 13) and the rotating body (see the worm wheel 12) are specified as described above, the rotating body (see the worm wheel 12) is connected via the driving means (see the worm 13). It is possible to secure a sufficient torque necessary to drive the rotating body (see worm wheel 12) while reducing the size and power consumption of the driving source (see the reversible motor 14) to be driven. There is an effect that can be done.

In this embodiment, the driving means and the rotating body are exemplified as the combination of the worm 13 and the worm wheel 12, but the combination of the small diameter gear and the large diameter gear, the combination of the small diameter sprocket and the large diameter sprocket, and the small diameter gear are used. Even if the pulley and the large-diameter pulley are combined, the same action and effect are obtained.

Further, since the locus of the through hole 16 formed in the rotating body (see the worm wheel 12) and the periphery of the hole 3 of the artificial turf 2 described above are associated with each other in the vertical direction, the rotating body (see the worm wheel 12) An arbitrary undulation can be formed around the hole 3 by the slider 17 corresponding to the position change of the through hole 16 due to the rotation, and the position of the through hole 16 (the position of the slider 17) follows the locus. The effect is that the undulation form can be changed each time it changes.

Furthermore, since the plurality of cuts 25 as described above are formed in the plurality of thin plates 23 for forming undulations, when the thin plate 23 is displaced in the vertical direction by the movement direction converting means 22, the plurality of cuts 25 described above are formed. This has the effect of preventing distortion of the thin plate 23 and improving the durability of the thin plate 23. Furthermore, since the outer peripheral portions of the plurality of thin plates 23 for forming the undulations are held in a displaceable manner, the movement direction conversion means 22 allows the upper and lower displacements of the plurality of thin plates 23 to be performed more smoothly. At the same time, the distortion of the plurality of thin plates 23 can be reliably served.

Moreover, when the golf ball B led out to the lower side of the hole is supplied to the stance position S of the artificial turf 2, the golf ball B on the side of the hole moves to the lower side of the lower side of the first conveyor 32. The golf ball B is slightly accelerated by the first conveyor 32, and then the golf ball B is inclined from the ball delivery section 41 on the upper part of the first conveyor 32. It rolls on the upper surface of the means (see the guide rail 34) and is supplied to the ball receiving portion 47 of the second conveyor 33 at the position corresponding to the stance. Next, the golf ball B of the ball receiving portion 47 is re-lifted upward from the lower part of the second conveyor 33, and corresponds to the stance position S of the ball sending-out part (see the disposition part of the ball outlet member 48) of this upper part. It is transported to the part where

In this way, the golf ball B slightly accelerated by the first conveyor 32 rolls on the upper surface of the inclined guide means (see the guide rail 34), so that the rolling resistance due to the material of the golf ball B and the dimples is increased. Even so, the above-mentioned guide means (see the guide rail 34) can be supplied from the lower side of the hole portion to the portion corresponding to the stance position S at a slight inclination angle θ of, for example, about 5 degrees. As a result, there is an effect that the overall height of the training machine frame (see the machine frame 1) can be reduced and the apparatus can be made compact.

In addition, since the first and second conveyors 32 and 33 described above are provided with dog belts (belts with protrusions), the golf ball B in the lower position is described above even though the conveyor has a simple structure. With the dogs 39 and 45, it can be easily transported to the upper position.

In the correspondence between the configuration of the present invention and the above-described embodiment, the rotating body of the present invention corresponds to the worm wheel 12 of the embodiment, and similarly, the driving means corresponds to the worm 13, and The machine frame corresponds to the machine frame 1, the guide means corresponds to the guide rail 34, and the dog belt corresponds to the endless belts 38 and 44 having the dogs 39 and 45. It is not limited to.
