(Embodiment 1)
The pond facility according to Embodiment 1 of the present invention is a pond facility provided at a golf driving range. By installing a pond facility at the golf driving range that resembles the pond installed at a real golf course, golfers can practice while being aware of the pond as a penalty area, and can improve their golf skills. . For the owner of a golf driving range, by providing a pond facility at the driving range, the area of artificial turf laid on the driving range can be reduced. Furthermore, if the area where artificial turf is laid can be reduced, the cost of disposing of artificial turf, which becomes industrial waste, can be reduced.

Hereinafter, the pond facility of this embodiment will be described in detail with reference to the drawings. As shown in FIGS. 1A and 2B, the pond facility 1 includes a pond 10 and a green 30 installed inside the pond 10. The green 30 is different from an actual green and is a simulated green made of artificial grass, a waterproof sheet, a low-repulsion mat, etc., but in this embodiment, the simulated green is referred to as a green. FIG. 1 shows the pond facility with the pond 10 filled with water, and FIG. 2 shows the pond facility with the pond 10 drained. A green 30 is arranged behind the pond 10. The golf practitioner's batting area is installed in a place where the pond 10 is easily visible and has a good view, such as the front side of the pond 10.

As shown in FIG. 1(a), the pond 10 has a shape extending in the front-rear direction, and in this embodiment, is formed into a substantially rectangular shape when viewed from above. As will be described later, the golf balls that have fallen into the pond 10 are moved to the rear of the pond and recovered by a gate mechanism provided in a pit 70 provided at the rear end. Therefore, the rear end of the pond 10 is formed in a shape that slopes toward the pit 70 when viewed from above so as to easily collect golf balls that have moved to the rear of the pond.

The pond 10 is constructed by digging into the ground and laying concrete or a waterproof sheet on its surface. Alternatively, construction may be carried out by laying a synthetic resin tank molded into a predetermined pond shape. The pond 10 and green 30 can be selected to have dimensions that match the size of the golf driving range in use. In this embodiment, a golf practice range with a distance of 100 to 150 yards to the net is used, and the dimensions of the pond 10 are preferably 500 mm deep, 30 m wide, and 50 m deep.

As shown in FIG. 2, the pond 10 includes a bottom portion 20, a side wall 11 surrounding the outer periphery of the pond 10, and a ball collecting groove 40 formed in the bottom portion 20. In the present invention, unless there is a particular restriction, the height of the water surface when the pond 10 is filled with water will be described as a "reference height" (H).

The side wall 11 is a wall extending substantially vertically from the outer periphery of the pond 10, and is formed of concrete or the like. The height of the side wall 11 is set to be the same as or higher than the reference height.

A first receiving portion 21 and a second receiving portion 22 are disposed on the bottom portion 20 and are separated by a ball collecting groove 40 extending in the front-rear direction. The first receiving part 21 and the second receiving part 22 are receiving parts for receiving golf balls that have fallen into the pond 10, and the first receiving part 21 is on the right side of the ball collecting groove 40, and the second receiving part 22 is on the right side of the ball collecting groove 40. It is placed on the left side of 40. Further, the first receiving portion 21 and the second receiving portion 22 are each inclined downward toward the ball collecting groove 40 at a slope of θ1. Therefore, the golf balls that have fallen into the first receiving part 21 and the second receiving part 22 roll toward the ball collecting groove 40, as shown in FIG. 1(b). Here, the slope (θ1) of the first receiving portion 21 and the second receiving portion 22 is 0.5 to 5%, preferably 1 to 3%.

As shown in FIG. 2, the ball collection groove 40 is a groove extending vertically from the center of the pond 10 in the left-right direction. The ball collecting groove 40 is arranged to pass below the green 30. By arranging the ball collecting groove 40 so as to pass below the green 30, golf balls that have hit a support portion (to be described later) that supports the green 30 underwater can be smoothly introduced into the ball collecting groove 40.

The ball collecting groove 40 is formed by, for example, a commercially available U-shaped tube. The joint between the ball collecting groove 40 and the bottom part 20 is such that the upper end of the U-shaped tube is at the same height as the top surface of the bottom part 20 so as to receive the golf ball rolling on the bottom part 20, as shown in FIG. , lower than that. Note that the ball collecting groove 40 is not limited to a U-shaped pipe, and may be formed of cast-in-place concrete. Further, as shown in FIG. 3, the ball collecting groove 40 is inclined downward by θ2 from the front to the rear of the pond 10, and water flows from the front to the rear. The slope of the ball collecting groove 40 is preferably 0.5% to 3%.

As shown in FIG. 2, the upstream (front) end of the ball collecting groove 40 communicates with a supply groove 50 into which water is supplied, and the downstream (rear) end communicates with a pit 70, which will be described later. It communicates with the transfer groove 60 via a gate mechanism. A water-sphere separator is installed downstream of the transfer groove 60. The transfer groove 60 preferably has a downward slope of 0.5-3% towards the water-sphere separator.

In such a pond facility 1, golf balls that have fallen into the first receiving part 21 and the second receiving part 22 are transferred to the ball collection groove 40 due to the slope (θ1) of the first receiving part 21 and the second receiving part 22. Due to the slope of the ball collecting groove 40, the ball rolls within the ball collecting groove 40 from the front direction to the rear direction. Then, the golf balls are sent to the transfer groove 60 by a gate mechanism provided in the pit 70, passed through a water-ball separator, and are recovered and returned to the batting box.

The green 30 is placed behind the pond 10. By being placed at the rear of the pond 10, it becomes easier to visually recognize the target point from the batting box installed on the front side of the pond facility 1. As shown in FIGS. 4(a) and 4(b), the green 30 is constructed by fixing artificial turf 30d to the surface of a frame formed by a frame to be described later, and has a circular upper surface portion 30a and an upper surface portion when viewed from above. An inclined part 30b is provided which is inclined downward from around 30a toward the pond 10. A hole 30c shaped like a cup may be provided in the upper surface 30a of the green 30. Note that FIG. 4(b) is a front view seen from the line of arrow CC in FIG. 4(a). Further, in order to remove golf balls accumulated on the upper surface 30a of the green 30, a ball removing device (not shown) may be attached to the upper surface 30a of the green 30. When using a ball ejector, the timer switch is set to supply electricity to operate it. The ball removing device includes a ball removing rod, one end of which is placed at the center of the upper surface 30a of the green 30, and the ball removing rod is rotated about the center of the green 30 so as to stroke the surface of the upper surface 30a. Sweep a golf ball by rotating it.

Next, the structure of the green 30 will be explained. As shown in FIGS. 5 to 9 and 13, the green 30 has a supporting part 80 fixed to the concrete of the bottom part 20, a plurality of frames 31 serving as a framework are installed on the supporting part 80, and a plurality of frames 31 are mounted on the frames 31. It is formed by stretching a green floor panel 32 and fixing artificial grass 30d thereon.

The support section 80 includes a plurality of support units 91 and supports the green 30, as shown in FIGS. 5(a) and 5(b). As shown in FIG. 5(a), the plurality of support units 91 are installed concentrically at intervals under the green 30. The position of the support unit 91 is indicated by a black circle in the drawing. The support section 80 includes a central support unit 91a in which a plurality of support units 91 are arranged concentrically at a certain distance from the center of the green 30, and a plurality of support units 91 arranged concentrically outside the central support unit 91a. It consists of disposed tip support units 91b.

One support unit 91, as shown in FIGS. 5(b) and 10, includes a pedestal receiving prismatic anchor 81 and a support 90 connected to the top of the pedestal receiving prismatic anchor 81. The frame receiving prismatic anchor 81 and the support column 90 are made of, for example, a steel member.

As shown in FIG. 9, the frame receiving prismatic anchor 81 includes an anchor bolt 82, a top portion 83, and a reinforcing bar 84. The anchor bolt 82 is formed into a triangular prism, and its corners are arranged in a direction opposite to the direction of the rolling golf ball. That is, the base of one of the triangles in the horizontal cross section of the triangular prism is set toward the ball collecting groove 40, and the apex of the triangle is set toward the rolling golf ball. All the anchor bolts 82 arranged in the pond 10 are arranged with the base of the triangle facing the ball collecting groove 40 and the apex facing the rolling golf ball, as shown in FIG. Therefore, as shown in FIG. 11, even if the golf ball that has fallen into the first receiving part 21 hits the anchor bolt 82, it will move from the apex of the triangle of the anchor bolt 82 to the base, and will not stay and concentrate. It rolls toward the groove 40. The golf ball that has fallen into the second receiving part 22 also rolls toward the ball collection groove 40 without being retained by the anchor bolt 82, like the golf ball that has fallen into the first receiving part 21.

Although the anchor bolt 82 has been described as having a triangular prism shape, it may have any shape as long as it does not stop the movement of the golf ball rolling on the bottom portion 20. That is, it is sufficient that the surface facing the direction in which the golf ball rolls is formed in a convex shape when viewed from above. An example is shown in FIGS. 12(a) to 12(d). The arrow in the figure indicates the direction in which the golf ball rolls. FIG. 12(a) shows an anchor bolt 82 having a triangular prism shape, and the apex of the triangular cross section is arranged to face the golf ball. FIG. 12(b) shows an anchor bolt 82 in the form of a square prism, with the corners of the square cross section facing the golf ball. FIG. 12(c) shows an anchor bolt 82 that is a combination of a square pole and an angle iron, and the triangular apex of the angle iron is arranged to face the golf ball. FIG. 12(d) shows a cylindrical anchor bolt 82.

No matter which anchor bolt 82 is used, the surface facing the direction in which the golf ball rolls is convex, and the golf ball moves smoothly into the ball collection groove 4 without being restricted in movement by the anchor bolt 82. Roll up to. The anchor bolts 82 shown in FIGS. 12(a) to 12(d) are appropriately selected depending on the inclination angles of the first receiving part 21 and the second receiving part 22, and can be used alone or in combination. In addition, by installing an auxiliary device such as a water spray device (not shown) on the side wall 11 that sprays water toward the golf balls that have fallen onto the first receiving portion 21 and the second receiving portion 22, the auxiliary device and the The golf ball can also be rolled efficiently by combining with the anchor bolts 82 disclosed in a) to (d).

As shown in FIG. 9, the top portion 83 is a disc-shaped flange connected to the top of the anchor bolt 82, and has a plurality of bolt holes 83a formed along the circumference. A strut 90, which will be described later, is placed on the upper surface of the top 83, and the strut 90 and the pedestal prismatic anchor 81 are connected by passing bolts through bolt holes 83a of the top 83 and bolt holes of the strut 90.

As shown in FIGS. 9 and 10, the reinforcing bar 84 is an iron rod welded to the lower part of the anchor bolt 82, and the lower part is bent outward. Three reinforcing bars 84 are welded along the outer periphery of the lower part of the anchor bolt 82. When fixing the frame receiving square column anchor 81 to the bottom part 20, the anchor bolt 82 is pushed into the concrete poured into the bottom part 20 to the position where the reinforcing bar 84 is buried.

The support column 90 connects the frame receiving prismatic anchor 81 and the frame 31, as shown in FIGS. 7A and 7B and FIG. The support column 90 includes a main body part 90a, an upper flange 90b attached to the upper part of the main body part 90a, and a lower flange 90c attached to the lower part. Bolt holes 90bb are formed in the upper flange 90b, and bolt holes 90cc are formed in the lower flange 90c. By inserting and fastening bolts into the bolt hole 90cc and the bolt hole 83a of the top portion 83, the support column 90 and the pedestal support prismatic anchor 81 are connected. A connecting portion 90d formed of a cylindrical pipe and extending in the horizontal direction is attached to the main body portion 90a. The connecting portion 90d is attached only to the outermost support unit 91, as shown in FIG. 5(b). The connecting portion 90d has its tip connected to the outermost frame of the main member 31a to support the main member 31a at a predetermined angle. The frame 31 and the support column 90 are connected by inserting and fastening bolts into the bolt hole 90bb of the upper flange 90b and the first bolt hole 31da of the support member 31d.

The frame 31 is attached on the support column 90, as shown in FIGS. 5(a), 7(b), and 9. The frame 31 is a long frame made of steel, and by combining a plurality of frames 31, a framework for fixing the artificial grass 30d is formed. As shown in FIGS. 5(a) and 5(b), a square pillar-shaped green center frame 33 is installed in the center of the green 30 to fix one end of the frame 31.

As shown in FIGS. 5(a) and 6(b), the plurality of frames 31 forming the framework include a main member 31a, a tip member 31b, and a central member 31c. The main member 31a is a frame group formed by arranging a plurality of frames 31 radially outward from the green center frame 33. The end of the main material 31a opposite to the end fixed to the green center pedestal 33, that is, the outer end, is formed to be inclined downward. By tilting it downward, the shape of the slope portion 30b of the green 30 is formed.

The tip member 31b and the central member 31c are arranged at the lower part of the main member 31a, as shown in FIGS. 5(a) and 6(b). The central member 31c is a frame group in which a plurality of frames 31 are connected by a support member 31d and arranged concentrically with the green center frame 33. Like the central member 31c, the tip member 31b is a frame group in which a plurality of frames 31 are connected by a support member 31d, and is arranged concentrically with the green center mount 33 and outside the central member 31c. A plurality of first bolt holes 31da and a plurality of second bolt holes 31db arranged outside the first bolt holes 31da are formed in the support member 31d. The pair of frames 31 are connected by passing a bolt through the second bolt hole 31db.

By assembling the main member 31a, the tip member 31b, and the central member 31c, a spider web-like skeleton is formed when viewed from above, as shown in FIG. 5(a). The central member 31c is arranged to overlap the center support unit 91a, and the tip member 31b is arranged to overlap the tip support unit 91b. The main member 31a, the tip member 31b, and the central member 31c are connected at their intersections. This connection point overlaps with the position where the center support unit 91a and the tip support unit 91b are arranged. Moreover, the support units 91 are arranged at every other one of the plurality of main members 31a.

The green floor panel 32 is placed on a framework formed by a main member 31a, a tip member 31b, and a central member 31c, as shown in FIGS. 5(a), 6(b) and 6(a). The green floor panel 32 is a combination of panel units 32a that are long boards made of wood. Note that an aluminum plate or a plate made of FRP (Fiber Reinforced Plastics) may be used as the panel unit 32a. An integrated green floor panel 32 is formed by laying the panel units 32a on a framework formed by the frame 31. Specifically, as shown in FIGS. 5(a) and 6(a), a panel unit 32a is attached between a pair of adjacent frames 31 of the main material 31a to match the spacing between the pair of frames 31. The length of the panel unit 32a is gradually increased from the center of the green 30 toward the outer periphery in order to attach the panel unit 32a without any gaps on a framework having a circular appearance by combining a plurality of frames 31.

As shown in FIGS. 8 and 13, a pair of legs 32b extending downward at a predetermined interval are attached to the lower part of the panel unit 32a. The panel unit 32a is positioned by inserting the pair of legs 32b of the panel unit 32a between a pair of adjacent frames 31. The length L1 of the panel unit 32a is set so that the length of the portion projecting outward from the leg portion 32b is 1/2 of the width L2 of the frame 31. By setting such a length, the panel units 32a can be spread over the framework formed by the frame 31 without any gaps.

As shown in FIG. 13, a waterproof sheet 34 is stretched over the panel units 32a. Then, the green 30 is formed by fixing the artificial grass 30d on the waterproof sheet 34. Specifically, artificial turf 30d having a standard width (910 mm, 1820 mm, etc.) is cut to match the predetermined upper part of the green 30 and sewn in a factory or on-site. The center and outer periphery of the sewn artificial grass 30d are fixed to the waterproof sheet 34 with adhesive or staples.

In addition, the shape of the frame formed by the main member 31a, the tip member 31b, and the central member 31c depends on how the individual frames 31 are arranged and how the lengths of the individual frames 31 are determined. Can be changed. In this embodiment, by designing the length of the rear frame 31 of the main material 31a to be shorter than the length of the front frame 31, the green 30 The width of the inclined portion 30b can be made wider at the front than at the rear. That is, the main member 31a is designed to have a gentler slope and be longer at the front of the green 30, and is designed to have a steeper slope and become shorter toward the rear of the green 30. By designing the shape of the main material 31a in this way, the slope part 30b has a gentle slope and is long in the front part of the green 30, so that the golf ball can roll down the slope of the long slope part 30b and land on the green 30. . By providing such an inclined portion 30b, a golf practitioner can enjoy the feeling of playing on an actual golf course.

In this way, by changing the shape of the frame formed by the main member 31a, the tip member 31b, and the central member 31c, construction of various green shapes is possible, and green designs with variations are possible.

When designing the green, it is also possible to design the green 30 so that the upper surface 30a is not a perfect circle. Since the top surface 30a of the green 30 is not a perfect circle, when the ball removal device is operated to shake off golf balls, the ball removal rod may be insufficient in length or protrude from the top surface 30a. Therefore, if the top surface portion 30a of the green is not designed to be a perfect circle, the ball removal rod may be made to expand and contract.

A ball collection groove 40 passes through the lower part of the green 30 constructed in this manner. As shown in FIGS. 4(a), 5(a), and 5(b), the ball collecting groove 40 extends in the length direction (back and forth direction) of the pond 10 and extends through the diameter of the circular green 30. will be placed in By arranging the ball collecting groove 40 so as to pass through the diameter of the circular green 30, the design and construction of the bottom of the green 30, such as the placement position of the anchor bolt 82, becomes easier.

Next, the gate mechanism installed in the pit 70 will be explained. 14 shows a gate mechanism using a flap gate, FIG. 14(a) is a top sectional view of the gate mechanism, (b) is a side sectional view, and (c) shows the flap gate from the X direction of (b). This is a view. As shown in FIG. 14, the gate mechanism 200 includes a gate section 210 and a drive section 220.

The gate portion 210 includes an angled lever 211, a flap gate 212, and a gate frame 213 that is opened and closed by the flap gate 212. One end of the angled lever 211 is connected to a bearing of a bearing stand 211a installed at the bottom of the ball collecting groove 40, and is maintained in a state inclined to the right when the flap gate 212 is closed. The other end of the angled lever 211 is connected to one end of a connecting bar 224, which will be described later. Further, one end of the angled lever 211 is connected to the flap gate 212 via a connecting pin 211b provided on the bearing. The angled lever 211 and the flap gate 212 are connected in a bent chevron shape when viewed from the side, are connected by a connecting pin 211b at the top of the mountain, and move in the direction of the arrow around the connecting pin 211b. When the angled lever 211 rotates counterclockwise around the connecting pin 211b by the connecting bar 224, the flap gate 212 opens, and when the angled lever 211 rotates clockwise, the flap gate 212 closes.

The drive unit 220 is disposed within the pit 70 and includes a deceleration motor 222, a circular rotary plate 223 attached to the deceleration motor 222, a pair of limit switches 221, and a connection bar 224.

The rotation shaft of the deceleration motor 222 is arranged parallel to the bottom of the pit 70, and the rotation center of the circular rotary plate 223 is connected to this rotation shaft. The rotary plate 223 is rotated clockwise or counterclockwise by the rotation of the deceleration motor 222. The connection bar 224 is formed in a downward U-shape, and one end of the U-shaped connection bar 224 is connected to the outer periphery of the circular plate of the rotating plate 223, and the other end is connected to one end of the angled lever 211. Concatenated. The connecting bar 224 swings in the left-right direction as the rotary plate 223 rotates. Two limit switches 221 are disposed facing each other on the outside of the rotary plate 223, and when the connecting bar 224 comes into contact with them, the fully open position and the fully closed position of the gate are detected.

When the flap gate 212 is closed, the angled lever 211 tilts to the right as shown by the solid line in FIG. Rotation has stopped. When the deceleration motor 222 is driven in this state and the rotating plate 223 rotates counterclockwise, the connecting bar 224 swings to the left, causing the angled lever 211 to tilt to the left. Then, the flap gate 212 rotates upward around the connecting pin 211b to open the gate. When the gate is opened, the ball collection groove 40 and the transfer groove 60 are communicated with each other through the opening 11a provided in the side wall. When the rotary plate 223 rotates 180 degrees from the closed state of the flap gate 212, it comes into contact with the left limit switch 221, so that the rotation of the deceleration motor 222 is stopped. When the flap gate 212 opens, the golf ball that has fallen into the ball collection groove 40 moves to the transfer groove 60.

A method for recovering golf balls accumulated on the bottom portion 20 will be described with reference to FIG. 15. The left half of FIG. 15(a) is a top view of a state in which the pond 10 is full of water, and the right half of FIG. 15(a) is a top view of a state in which water is drained from the pond 10. FIG. 15(b) is a front view of FIG. 15(a) when the pond 10 is full of water, as seen from the line of arrow EE.

First, a gate (not shown) installed in the transfer groove 60 is closed. Then, the deceleration motor 222 is rotated to open the flap gate 212. The flap gate 212 is opened by operating the deceleration motor 222 at a set time. The time to open the flap gate 212 is usually set early in the morning or at the end of the day, avoiding business hours. Please note that depending on the number of spare balls, we may have no choice but to collect them even during business hours. In this case, the golf ball is washed away by lowering the water level in the first receiving part 21 and the second receiving part 22 while opening the gate and letting water in the pond flow into the transfer groove 60. At the same time, water is supplied from the supply groove 50 so that the water level of the pond does not fall abnormally. This operation is performed with manual adjustments.

When the flap gate 212 is opened, the water in the pond 10 is drained. As the water is drained, the water level in the pond 10 decreases, and the golf balls accumulated on the bottom 20 roll on the slopes of the first receiving part 21 and the second receiving part 22 toward the ball collecting groove 40. A golf ball that has fallen onto the bottom 20 may roll toward the ball collection groove 40 due to the slope of the bottom 20 itself, but by draining the water, the golf ball may roll toward the first receiving portion 21 and the second receiving portion 22. All the remaining golf balls can be rolled into the ball collection groove 40. Since the slope (θ1) of the first receiving portion 21 and the second receiving portion 22 is as gentle as 1 to 3%, there is no need to excavate much earth and sand when constructing the pond 10. Furthermore, since the water depth can be made shallow, the amount of water stored in the pond 10 can be reduced. When the amount of water stored in the pond 10 is small, the volume of the circulating water pit for storing water discharged when golf balls are recovered can be reduced.

Under the green 30, the rolling golf ball passes between or hits the anchor bolts 82 and rolls toward the ball collection groove 40. The anchor bolt 82 is formed into a triangular prism and is arranged so that the triangular apex of the cross section of the triangular prism faces the rolling golf ball. Therefore, as shown in FIGS. 15(a) and 15(b), even if the golf ball hits the anchor bolt 82, the golf ball can be moved to the ball collection groove 40 without being prevented from rolling by the anchor bolt 82.

The golf balls that have fallen into the first receiving part 21 and the second receiving part 22 roll into the ball collecting groove 40 and are moved from the ball collecting groove 40 to the transfer groove 60 through the gate. The golf balls sent to the transfer groove 60 are sent to a water-ball separator, separated from water, and recovered. When a preset time has elapsed, the deceleration motor 222 rotates in reverse and the flap gate 212 is closed. Thereafter, water is supplied from the circulating water pit to the pond via the supply groove 50, and the pond becomes full of water.

(Modified example)
In the first embodiment, the pond 10 has a substantially rectangular shape, but may have another shape. When determining the shape of the pond 10, it is necessary to consider the slope of the bottom 20 of the pond 10. That is, if the slope of the receiving portion toward the ball collecting groove 40 can be maintained preferably at 3%, the golf balls that have fallen onto the bottom portion 20 can be caused to roll into the ball collecting groove 40 at the same time as being drained. In addition, the ball collection groove 40 needs to be sloped downward from the front to the rear of the pond 10 so that the golf ball that falls into the ball collection groove 40 also rolls from the front end of the pond 10 toward the rear end. be. As long as this condition is satisfied, it is possible to design ponds with various shapes.

FIG. 16 shows a modification in which the shape of the pond 10 is not rectangular. In the modified example, while maintaining the slope of the receiving part at least 3%, the height between the deepest point of the receiving part, that is, the starting position of the ball collecting groove, and the upper end of the side wall (hereinafter referred to as side wall receiving part height h). In addition to determining the maximum height at which the maximum height is determined, the inclination of the ball collecting groove is determined. FIG. 16 is an external view of the pond 10 designed based on such a method when it is filled with water.

The pond 10 completed while maintaining the slope of the bottom at 3% can be made wider at the rear than at the front, as shown in FIG. 16, and the green 30 can be placed at a wider position at the rear. If the pond 10 is shaped so that the width of the rear part is widened, the field of view will be widened for a golf practitioner who hits a golf ball from the batting area. Further, since the green 30 is arranged at the rear of the pond 10, the width of the pond 10 surrounding the green 30 is widened, and the area where golf practitioners can practice is widened.

(Embodiment 2)
In Embodiment 1, the pond facility 1 including one green 30 in one pond 10 has been described, but the present invention is not limited to such a structure. In this embodiment, the pond 10 is divided into two by the separation wall 12, and one green is constructed in each divided area.

As shown in FIGS. 17 and 18, the pond facility 100 includes a pond 10, and a first green 301 and a second green 302 installed inside the pond 10. The pond 10 includes a bottom portion 20 and a side wall 11 surrounding the outer periphery of the pond 10. The material of the bottom 20 of the pond 10 and the material of the side wall 11 are the same as in Embodiment 1, and their explanation will be omitted.

The ponds 10 are partitioned by separation walls 12 at positions where the internal volumes are approximately the same. The separation wall 12 is a wall that stands up from the bottom 20 of the pond facility 100 and extends in the front-rear direction. The upper end of the separation wall 12 is 0 to 100 mm below the reference height H, more preferably 30 to 90 mm. If the upper end of the separation wall 12 is below the water surface, the entire structure can have the appearance of one large pond. The pond 10 is divided by a separation wall 12 into a first water storage section 10a on the left side and a second water storage section 10b on the right side.

The bottom portion 20 includes a third receiving portion 23 and a fourth receiving portion 24, which are the bottom of the first water storage portion 10a, and a fifth receiving portion 25, which is the bottom of the second water storage portion 10b. A first ball collection groove 41 extending in the front-rear direction is provided in the bottom portion 20 of the first water storage portion 10a at a position a predetermined distance away from the separation wall 12. The third receiving part 23 and the fourth receiving part 24 are separated by the first ball collecting groove 41, and the third receiving part 23 is arranged on the left side of the first ball collecting groove 41, and the fourth receiving part 24 is arranged on the right side. be done. The third receiving portion 23 and the fourth receiving portion 24 are inclined downward toward the first ball collecting groove 41 at a slope of θ3 and a slope of θ4, respectively. The first ball collecting groove 41 may be formed at any position in the left-right direction of the first water storage portion 10a. The angle of the slope (θ3, θ4) changes depending on the position of the first ball collecting groove 41. The slope (θ3, θ4) is 0.5 to 5%, preferably 1 to 3%, as in the first embodiment, and within this range, the position of the first ball collecting groove 41 and the slope (θ3, θ4) ) to set the angle.

A second ball collecting groove 42 is formed at the bottom of the second water storage part 10b along the separation wall 12, and the fifth receiving part 25 is inclined downward at a slope of θ5 toward the second ball collecting groove 42. ing. The slope (θ5) of the second ball collecting groove 42 can also be set within a range of 0.5 to 5%, preferably 1 to 3%. Like the ball collecting groove 40 of Embodiment 1, the first ball collecting groove 41 and the second ball collecting groove 42 extend downward from the front to the rear of the pond 10 at a slope of preferably 0.5 to 3%. is inclined to.

The first green 301 and the second green 302 are arranged behind the pond 10, as shown in FIG. The second green 302 is located in front of the first green 301. By arranging the two greens at different positions, it is possible to change the impression of the landscape given to golfers. Furthermore, the impression of the landscape may be changed by changing the size of the green.

A half of the first green 301 is placed in the first water storage section 10a shown in FIG. 18, and a half of the second green 302 is placed in the second water storage section 10b shown in FIG. 18. The first green 301 and the second green 302 are not entirely placed inside the pond 10, but a portion of the green, in this embodiment, a half of the green, is placed inside the pond 10. We are conducting a green design. By arranging half of the green in the pond 10 in this way, the pond facility 100 can be made larger while the size of the pond 10 is made smaller. With this kind of design, even if two greens are placed in the pond 10, the amount of golf balls that fall into the pond can be approximately the same as when one green is placed, and the number of golf balls to be collected will be reduced. It is possible to suppress the amount from increasing.

The first green 301 is supported by the support part 80 installed in the first water storage part 10a shown in FIG. 18, and the second green 302 is supported by the support part 80 installed in the second water storage part 10b shown in FIG. Supported by Since half of the first green 301 and the second green 302 are placed inside the pond 10, the support part 80 supports only the portions of the first green 301 and the second green 302 that are placed inside the pond 10. Just support it. As for the overall structure of the green, in contrast to Embodiment 1, for the above-ground parts other than the pond, the pedestal receiving prismatic anchor of the support part 80 is unnecessary, and a conventional construction method of above-ground installation may be used. The anchor bolt 82 of the support portion 80 is formed of a triangular prism as in the first embodiment. Since the anchor bolt 82 has a convex surface facing the direction in which the golf ball rolls, the golf ball will not be blocked from moving by the anchor bolt 82 and will not stay there.

Like the ball collecting groove 40 shown in FIG. 3, the first ball collecting groove 41 and the second ball collecting groove 42 are inclined downward from the front to the rear, and water flows from the front to the rear. The slope of the first ball collecting groove 41 and the second ball collecting groove 42 is preferably 0.5 to 3%. As shown in FIG. 18, the front (upstream) end of the first ball collection groove 41 is communicated with the first supply groove 51 that supplies water to the first water storage section 10a, and the rear (downstream) end The end portion communicates with the transfer groove 61 by opening a gate plate to be described later. The front side (upstream side) end of the second ball collection groove 42 is communicated with a second supply groove 52 that supplies water to the second water storage section 10b, and the rear side (downstream side) end is connected to a gate described below. Opening the plate communicates with the transfer groove 61. The first supply groove 51 and the second supply groove 52 are connected to a common third supply groove 53 on the upstream side. A direction conversion gate 54 is provided between the first supply groove 51 and the second supply groove 52, and by switching the direction conversion gate 54, the flow of water supplied from the third supply groove 53 is changed to the first supply groove 52. It is possible to switch between the supply groove 51 and the second supply groove 52. Note that, like the transfer groove 60, the transfer groove 61 preferably has a slope that slopes downward by 0.5 to 3% toward the water-sphere separator.

The first ball collecting groove 41, the second ball collecting groove 42, and the transfer groove 61 are connected via a gate mechanism 400 shown in FIGS. 19(a) to 19(c). The gate mechanism 400 that connects the first ball collecting groove 41 and the transfer groove 61 is provided in the first pit 71, and the gate mechanism 400 that connects the second ball collecting groove 42 and the transfer groove 61 is provided in the second pit 72. It will be done. Each gate mechanism 400 includes a drive section 401 and a gate section 402 that opens and closes the opening 11a by the drive section 401. The drive unit 401 is arranged in a first pit 71 provided downstream of the first ball collecting groove 41 and a second pit 72 provided downstream of the second ball collecting groove 42 .

The drive section 401 includes a motor 401a, a sprocket 401b attached to the upper part of the rotating shaft of the motor 401a, a sprocket 401c of the gate section 402, and a roller chain 401d that is stretched between the sprocket 401b and the sprocket 401c.

The gate part 402 includes a gate plate 402a, a nut 402b attached to the upper part of the gate plate 402a, a screw 402c screwed into the nut 402b, a bearing 402d bearing the upper part of the screw 402c, and a tip bearing 402e. Equipped with The gate plate 402a is guided by a gate guide 402f and moves up and down. Sprocket 401c is supported by a tip bearing 402e. As shown in FIG. 19(c), a cover 403 is placed over the top of the sprocket 401b, sprocket 401c, and roller chain 401d, although it is omitted in FIG. to prevent damage.

To activate the gate mechanism, follow the steps below. FIG. 19(b) shows a state in which the gate plate 402a is at the lowest position and the opening 11a is closed, and FIG. 19(c) shows a state in which the gate plate 402a is raised and the opening 11a is open. First, by rotating the motor 401a in a fixed direction, the sprocket 401b is rotated, and the sprocket 401c is rotated via the roller chain 401d. As the sprocket 401c rotates, the screw 402c rotates in a fixed direction. The rotation of the screw 402c causes the nut 402b to rise, and as the nut 402b rises, the gate plate 402a also rises. When the gate plate 402a rises, the opening 11a provided in the side wall 11 opens, and the first ball collecting groove 41 or the second ball collecting groove 42 and the transfer groove 61 are communicated with each other. The golf ball passes through the opening 11a and is transferred from the first ball collecting groove 41 or the second ball collecting groove 42 to the transfer groove 61.

The rotation of the gate plate 402a is stopped by a limit switch 404 attached to the sprocket 401b. That is, the limit switch 404 measures the number of rotations of the sprocket 401b, and stops the rotation of the motor 401a when the number of rotations reaches a predetermined number. After the golf balls are collected, the motor 401a is rotated in the opposite direction, the screw 402c is rotated in the opposite direction to the fixed direction, and the gate plate 402a is lowered to close the opening 11a. The opening time of the gate plate 402a is determined by setting a predetermined time using a set timer. After a predetermined period of time has elapsed, the closing switch is turned off.

(How to collect golf balls)
Next, a method for collecting golf balls according to this embodiment will be described with reference to FIGS. 17-19.

First, the water in the first water storage section 10a is drained. When draining water, the direction changing gate 54 is switched to a direction in which water is not supplied from the third supply groove 53 to the first supply groove 51. Then, the motor 401a installed in the first pit 71 is driven to rotate the screw 402c in a fixed direction to raise the gate plate 402a and open the opening 11a. The water accumulated in the first water storage portion 10a is discharged from the opening 11a.

As the water is drained, the golf balls remaining in the third receiving part 23 and the fourth receiving part 24 of the first water storage part 10a roll toward the first ball collection groove 41. The golf ball remaining at the lower part of the first green 301 rolls to the first ball collection groove 41 without being prevented from moving by the anchor bolt 82.

The golf ball that has fallen into the first ball collecting groove 41 reaches the vicinity of the gate plate 402a of the first pit 71 due to the inclination of the first ball collecting groove 41. Since the gate plate 402a is raised and the opening 11a is open, the golf ball passes through the opening 11a, is transferred to the transfer groove 61, and is transferred to the water-ball separator. The golf ball is stored after being washed, dried, etc., and then returned to the batting box. The water stored in the first water storage section 10a is stored in a circulating water pit (not shown). After the golf balls are collected, the direction conversion gate 54 is switched to the side that supplies water to the first supply groove 51, and the water stored in the circulating water pit is transferred from the first supply groove 51 to the first water storage section 10a. sent to.

Next, the water in the second water storage section 10b is drained. When draining water, the direction changing gate 54 is switched to a direction in which water is not supplied from the third supply groove 53 to the second supply groove 52. Then, the motor 401a installed in the second pit 72 is driven, the screw 402c is rotated in a fixed direction, the gate plate 402a is raised, and the opening 11a is opened. The water accumulated in the second water storage portion 10b is discharged from the opening 11a.

As the water is drained, the golf balls remaining in the fifth receiving section 25 of the second water storage section 10b roll toward the second ball collecting groove 42. The golf ball remaining at the lower part of the second green 302 falls into the second ball collection groove 42 without being prevented from moving by the anchor bolt 82 of the support part 80.

The golf ball that has fallen into the second ball collecting groove 42 reaches the vicinity of the gate plate 402a of the second pit 72 due to the inclination of the second ball collecting groove 42. Since the gate plate 402a is raised and the opening 11a is open, the golf ball passes through the opening 11a, is transferred to the transfer groove 61, and is transferred to the water-ball separator. The golf ball is stored after being washed, dried, etc., and then returned to the batting box. The water stored in the second water storage section 10b is stored in a circulating water pit (not shown). After the golf ball is collected, the direction change gate 54 is switched to the side that supplies water to the second supply groove 52, and the water stored in the circulating water pit is transferred from the second supply groove 52 to the second water storage section 10b. sent to.

In this way, the pond 10 is divided into the first water storage part 10a and the second water storage part 10b, and by draining water from each water storage part and recovering the golf balls, a circulating water pit is created in which the drained water is stored. The size of can be reduced.

In this embodiment, by providing two greens in the pond 10, golf practitioners can be provided with a variety of practice facilities.
