Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pond facility installed in a golf driving range that facilitates collection of golf balls.

Some so-called golf driving ranges have a pond that resembles an actual course. At such a golf driving range, a ball that has fallen into the pond can be recovered using a net or the like.

However, since golf balls have a higher specific gravity than ordinary balls, they are difficult to pick up when they sink in a pond, and the work of collecting them with a net is inefficient. For this reason, a slope is provided in the pond so that the golf balls roll along the slope and are collected in a ball collecting portion connected to the slope. There is a falling water ball collecting and washing device provided with a catching means for collecting discharged balls at the end (Patent Document 1). The pond is provided with multiple ball collecting parts, and a spiral branch pipe is provided in the soil below each ball collecting part. It is configured to be sent to the location of

Also, as a device for collecting golf balls, there is a collecting golf ball delivery device that conveys golf balls one by one without lumping them by a water stream (Patent Document 2). Golf balls are formed with many depressions in order to extend the flight distance, and the increased surface area increases the frictional resistance, making it difficult to move when gathered. Therefore, a large number of collected golf balls are stored in a ball storage tank, and a ball delivery path is provided around the bottom of the ball storage tank for aligning and moving the balls in the ball storage tank. A ball delivery water jet pipe for ejecting a water stream to move the golf ball to the ball delivery port side is arranged, and furthermore, a ball breaker for ejecting a water stream to break the overlapping golf balls generated in the vicinity of the ball delivery port. A water jet pipe is installed in the ball storage tank.

FIG. 1 of Patent Document 2 shows a mode in which a golf ball is recovered by a water flow in an inclined ball collecting groove provided in the ground of a golf driving range, the ball collecting groove having a ridge portion for water evacuation. It is a ball guiding passage provided with a plate, and a mode is described in which golf balls are transferred to the ball storage tank while rolling through the ball collecting groove.

However, as described in Japanese Unexamined Patent Application Publication No. 2002-100000, in order to gather the golf balls in the pond at a certain point by means of an inclination provided in the pond, it is necessary to provide an inclination to the extent that the balls can be recovered by rolling. 2, the pond is depicted with an inclination of about 30°, which increases the water depth of the pond and increases the construction cost of the pond. The pond described in Patent Document 1 includes two large and small islands, and is large with a length of 90 to 100 m, a width of 40 m, and a maximum depth of 3 m. Balls gathered in the ball gathering part are discharged to the water storage tank together with the pond water through a drainage pipe laid on the ground at the bottom of the pond, so civil engineering work to collect the balls from the ball gathering part is also required. is necessary.

Further, Patent Document 2 has in common with Patent Document 1 the recovery of golf balls submerged in water in that the golf balls are recovered using water flow. It is a device for recovering a large number of golf balls at a golf driving range that has been hit continuously. In order to collect the golf balls by the water flow, the inclination of the ball collection groove is large, and the bottom of the ball storage tank is equipped with a water flow ejection pipe for sending the ball and a water flow ejection pipe for breaking the ball. It is necessary to install a pump and supply water at a predetermined pressure. If such a device is used as a pond facility, a large slope leads to an unnecessary increase in the water depth of the pond.

SUMMARY OF THE INVENTION In view of the above situation, it is an object of the present invention to provide a pond facility that can be installed in a golf driving range and that facilitates collection and laying of golf balls.

The inventor of the present invention has found that if the bottom of the water tank that constitutes the pond is divided into two or more, the rolling distance of the fallen ball can be shortened and the water depth of the pond can be made shallower, and that the adjacent golf balls do not come into contact with the bottom of the water tank. By arranging a plurality of rolling paths at intervals, contact between golf balls can be avoided and smooth rolling of the balls can be ensured. Then, the inventors found that the golf balls can be recovered from the water tank by reducing the depth of excavation in the lower part of the pond by introducing the golf balls into the transfer groove provided on the outer periphery of the pond, thus completing the present invention.

That is, the present invention provides a pond facility disposed at a golf driving range, comprising a water tank and a water-sphere separating device,
The water tank includes a separation wall that divides at least the bottom into two or more parts, a receiving part that receives a dropped golf ball and is disposed in each of the bottoms divided by the separation wall, and a golf ball that rolls on the receiving part. a golf ball transfer groove A into which the ball is introduced;
The end of the transfer groove A is connected to a golf ball transfer groove B provided on the outer periphery of the water tank through an openable/closable gate provided on the side wall of the water tank,
The water-ball separator separates the water transferred from the transfer groove B and collects the golf balls to provide a pond facility.

Further, according to the present invention, the receiving portion has a plurality of rolling paths along which the golf balls roll toward the transfer groove A, and the rolling paths are arranged at intervals such that adjacent golf balls do not come into contact with each other. and provides the said pond facilities.

Further, according to the present invention, the receiving portion has a slope of 1 to 7% that descends toward the transfer groove A,
The transfer groove A has a slope of 0.1 to 3% descending toward the transfer groove B,
Said transfer groove B is characterized by having a gradient of 0.1-5% descending towards said water-sphere separator, providing said pond facility.

According to the present invention, the golf balls that have fallen into the water tank can be transferred to the water-sphere separating device through the receiving portion for receiving the dropped golf balls, the golf ball transfer groove A, and the golf ball transfer groove B, and recovered. and easy to install.

The present invention is a pond facility arranged at a golf driving range. Golf courses are provided with ponds filled with water in depressions in the ground for the strategic purposes of playing strategies, fire extinguishing, and tree growing. Even a driving range may have a pond in order to create an environment similar to that of a golf course. If a pond is provided, the artificial turf area will be relatively reduced. Artificial turf is commonly laid in golf driving ranges, but it is damaged quickly, and if the use of artificial turf is reduced, the disposal cost of replacement material, which becomes industrial waste, can also be reduced. Furthermore, just like a golf course, putting a golf ball in the water will result in a penalty, which will improve your golf technique. The pond facility of the present invention only needs to have a water tank capable of storing water, and the water tank may be dug into the ground, or the surface thereof may be covered with concrete or a waterproof sheet. Alternatively, a synthetic resin tank molded into a predetermined pond shape may be laid. The present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing one preferred embodiment of the pond facility 100 of the present invention. The pond facility 100 has a water tank 10, and the water tank 10 has a side wall 12 and a bottom, and the bottom is divided by a separation wall 16 into at least two or more. FIG. 1 shows a mode in which two separation walls 16 form three bottoms 14A, 14B, and 14C. In the present invention, unless otherwise specified, the height of the water surface when the water tank 10 is full will be described as the "reference height". The height of the side wall 12 can be indicated by the distance from the bottom 14 to the reference height, but the depth from the reference height to the bottom 14 need not be constant over the entire surface of the water tank 10, and the side wall 12 has the reference height. It may have a higher portion. The bottom portion 14 has a receiving portion 20 for receiving a falling golf ball and a transfer groove A30 for transferring the golf ball from the receiving portion. The depth from the deepest part of the receiving part 20 not including the transfer groove A30 to the reference height is 100-700 mm, more preferably 150-600 mm. In a golf driving range, the water level when the water tank 10 is filled with water is preferably in the range of 0 to 80 mm, more preferably 10 to 70 mm, below the standard height.

The separation wall 16 is only required to divide the bottom portion 14 of the water tank 10 into two or more portions, and is arranged substantially vertically from the bottom portion 14 toward the water surface. The height of the separation wall 16 is preferably set within a range in which the upper end of the separation wall 16 does not protrude above the water surface when water is introduced into the water tank 10 . The height of the separation wall 16 is 0-100 mm below the reference height, preferably 10-90 mm. If the separation wall 16 is under the water surface, the appearance of one large pond can be ensured as a whole.

Each bottom portion 14 is provided with a receiving portion 20 for receiving a golf ball dropped into the water tank 10 and a transfer groove A30 into which the golf ball rolling on the receiving portion 20 is introduced. The receiving portion 20 is formed with an inclination (θ1) so that the golf ball can roll and move to the transfer groove A30. As shown in the bottom portion 14C of FIG. 1, the upper surface of the receiving portion 20 may be provided with a rolling path 22 for rolling the golf ball in a predetermined direction.

In the present invention, the transfer groove A30 provided in each bottom portion 14 also has a slope (θ2) that descends toward the transfer groove B50. Therefore, the slope (θ1) of the receiving portion 20 changes corresponding to the slope (θ2) of the transfer groove A30, and becomes deeper as it approaches the transfer groove B50. For example, assume that the most upstream point of the transferring groove A30 is the transferring groove A30T, the most downstream point of the transferring groove A30 is the transferring groove A30E, and the gradient (θ2) of the transferring groove A30 is 0.5%. Also, the length of the transfer groove A30 is assumed to be 10 m, and the length from the upper end of the receiving portion 20 to the transfer groove A30 is assumed to be 10 m. It is assumed that the rolling path 22 connected to the transfer groove A30T is the rolling path 22T and its gradient (θ1T) is 1.5%. In this case, the gradient (θ1E) of the rolling path 22E connected to the transfer groove A30E is 2%. FIG. 2A is a cross-sectional view taken along line AA of FIG. 1, showing the gradient (θ1T) of the most upstream rolling path 22T of the transfer groove A30. FIG. 2B is a cross-sectional view taken along line BB of FIG. 1, showing the slope (θ1E) of the rolling path 22E on the most downstream side of the transfer groove A30. The slope (θ1) of the receiving portion becomes deeper on the downstream side corresponding to the slope (θ2) of the transfer groove A30. The gradient (θ1) of the receiving portion 20 and the rolling path 22 descending toward the transfer groove A30 is preferably 1 to 7%, more preferably 1 to 5%, regardless of the gradient (θ2) of the transfer groove A30. . According to the present invention, since the bottom portion 14 of the water tank 10 is divided into a plurality of sections by the separation wall 16, the distance traveled by the golf ball falling into the water tank 10 can be shortened. It has been found that the golf ball can be moved smoothly even if there is. Although the above has been described using the rolling paths 22T and 22E, the same applies when the receiving portion 20 does not have the rolling paths 22. FIG.

The rolling path 22 formed in the receiving portion 20 can widely adopt one arranged so that adjacent golf balls can roll in the transfer groove A30 without contacting each other. An example of such a rolling path 22 is a U-shaped member obtained by cutting a pipe thicker than the diameter of a golf ball into a semi-circular shape and arranging them substantially parallel to each other. Alternatively, as shown in FIG. 3A, for example, a plurality of plate-like members 24 may be arranged substantially parallel to each other, and both corners of adjacent plate-like members 24 may be used as rolling paths 22 by receiving golf balls. good. Furthermore, as shown in FIG. 3B, instead of the plate-shaped object 24, a columnar object 26 is arranged substantially parallel to each other, and both outer contours of the columnar object 26 are arranged between the columnar objects 26 and 26. It may be used as the rolling path 22 by receiving the golf ball on the surface. Preferably, as shown in FIGS. 3A and 3B, the gap between the members arranged substantially in parallel is used as the rolling path 22 . Further, instead of the plate-like object 24 and the columnar object 26, hollow pipe-like objects can be arranged substantially parallel to each other. When the rolling path 22 is formed between the members, the golf ball moves while contacting two points of the adjacent members, compared to the case of the U-shaped object which rolls while contacting the inside at one point. Can move in a straight line.

For example, as shown in FIG. 3A, the rolling path 22 can be arranged by arranging a plurality of plate-shaped objects 24 in parallel and fixing them with screws 28 or the like. Further, as shown in FIG. 3B, a member 26 having a leg member 27 vertically fixed to the lower end of a cylindrical shape as a cylindrical member 26 is embedded and fixed in the bottom portion 14 so that the columnar shape is parallel. can also be formed. In either case, the gaps between the members are used as rolling paths 22, and cylindrical members 26 including plates 24 and legs 27 are fixed so that adjacent golf balls do not contact each other. By adjusting the inclination of the rolling path 22, the inclination (θ1) of the receiving portion 20 can be adjusted. For example, when a plurality of plate-like objects 24 are arranged in parallel to form the rolling path 22 in the receiving portion 20 as shown in FIG. By gradually adjusting the height of the plate-like object 24, the inclination (θ1) of the receiving portion 20 can be adjusted. Also, in the case shown in FIG. 3B, the slope (θ1) can be formed by fixing legs 27 of different lengths to the cylindrical object 26 .

The receiving portion 20 constitutes a part of the surface of the bottom portion 14 , and for example, when the bottom portion 14 is molded with concrete, the laid bottom portion 14 can be used as the receiving portion 20 as it is. Alternatively, the rolling path 22 may be formed by providing a groove in concrete. On the other hand, it is also possible to form a basket-like object in which the plate-like objects 24 are arranged at predetermined intervals in advance, and place or fix this on the bottom portion 14 . At this time, the gradient (θ1) can be adjusted to 1 to 7% by placing or fixing a slatted object on the bottom portion 14 so as to have a predetermined gradient (θ1).

The members forming the receiving portion 20 and the rolling path 22 are not limited, and may be metal, synthetic resin, composite members thereof, concrete, wood, porcelain, etc., and composite materials thereof. When synthetic resin is used, it may be a sliding grade member such as fluorine resin such as polytetrafluoroethylene, polyamide, polyacetal, ultra-high molecular weight polyethylene, polyethylene terephthalate, polyether ether ketone, polyphenylene sulfide. .

The position and number of the transfer grooves A30 provided in the water tank 10 are not particularly limited as long as they are positions where the golf balls rolling along the slope (θ1) of the receiving portion 20 can be recovered. In FIG. 1, bottoms 14B and 14C show an aspect in which two receiving portions 20 having a slope (θ1) and one transfer groove A30 for collecting golf balls transferred from these two receiving portions 20 are formed on the bottom portion 14A. 3A and 3B show a mode in which a transfer groove A30 is formed along the separation wall 16. FIG.

The transfer groove A30 can be composed of, for example, a commercially available U-tube. At this time, the joint between the transfer groove A30 and the receiving portion 20 is such that the upper end of the U-tube is aligned with the upper surface of the receiving portion 20 or the rolling path 22 so that the golf ball rolling on the receiving portion 20 can be recovered. Equal height or lower. 2A and 2B show a mode in which the upper ends of the transfer grooves A30 are buried under the ends of the rolling paths 22T and 22E. The inner width of the transfer groove A30 where the golf ball moves is 150-360 mm, more preferably 240-300 mm, and the depth is 150-360 mm, more preferably 240-300 mm. In addition, it is not limited to the U-shaped pipe, and may be installed using cast-in-place concrete.

FIG. 4A shows a side view taken along line CC of FIG. This is an example in which water is stored slightly below the reference height. The transfer groove A30 that receives the golf ball rolled from the receiving portion 20 has a slope (θ2) that descends toward the transfer groove B50. The slope (θ2) of the transfer groove A30 is determined in consideration of the size of the bottom portion 14 of the water tank 10 and the length of the transfer groove A30 so that the slope (θ1) of the receiving portion 20 is within the range of 1 to 7%. Designed. Preferably, the gradient (θ2) of the transfer groove A30 is 0.1-3%, more preferably 0.2-2%. Due to this slope (θ2), the golf ball introduced into the transfer groove A30 is moved toward the transfer groove B50 arranged outside the water tank 10 .

A gate 40 is provided at the downstream end of the transfer groove A30 to control the movement of the water in the water tank 10 and the golf balls to the transfer groove B50.

The structure of the gate 40 is not particularly limited, and the method of opening and closing the gate 40 may be a manual method, a power method using power such as electricity or hydraulic power, or an artificial method that opens and closes after artificially observing that a golf ball has accumulated. It may be of an automatic type in which a sensor or the like senses the pooling of golf balls and automatically opens and closes according to this sensing. FIG. 4A shows an example of an openable/closable gate 40 provided on the side wall 12 of the water tank 10 at the downstream end of the transfer groove A30. When the gate 40 is opened, the golf balls in the transfer groove A30 can move to the golf ball transfer groove B50 provided on the outer circumference of the side wall 12 together with the water.

The gate 40 shown in FIG. 4A includes a shielding member 40A having an arcuate surface and an opening/closing device 40B provided outside the water tank 10. As shown in FIG. The shielding member 40A has legs of a fan-shaped member 41A that radially support the shielding member 40A at its left and right ends. A shielding member 40A moves up and down in the center. The opening/closing device 40B is housed in a mass 40C arranged on an extension line of the transfer groove A30 and outside the water tank 10 and the transfer groove B50, and supports a support shaft 40D provided between the side wall 12 and the mass 40C. The end of the connecting member 40E is connected to the opening/closing device 40B and the shielding member 40A. A notch 52 is formed through the side wall 12 and the transfer groove B50 so that the golf ball and water in the transfer groove A30 can be introduced into the transfer groove B50 by releasing the shielding member 40A.

The gate 40 may have a shielding member 40A, a fan-shaped member 41A, a support shaft 40D, etc. separately prepared in advance, and a housing 44A assembled with the transfer groove A30. A perspective view of such a housing 44A is shown in FIG. 4B. A pair of support shafts 40D are formed on the opposite side surfaces of the rectangular tube, and the axial centers of two opposing fan-shaped members 41A integrally formed on the side surfaces of the shielding member 40A are rotatably fixed to the support shafts 40D. is set. A top surface of the housing 44A is partially open so as not to hinder the rotation of the shielding member 40A. 4C shows the positional relationship between the transfer groove 30, the side wall 12, the transfer groove B50, and the notch 52. As shown in FIG.

FIG. 5A shows a plan view of the gate 40 using the housing 44A, FIG. 5B shows its side view, and FIG. 5C shows a cross-sectional view taken along the line AA of FIG. 5A to explain the structure of the gate 40 in more detail. As shown in FIG. 5A, the mounting position of the housing 44A is the downstream end of the transfer groove A30, and is configured in a shape that can be fitted into the transfer groove A30. An opening/closing device 40B is accommodated in a mass 40C formed on an extension line of the transfer groove A30, and a connecting member 40E is pivotally supported by a support shaft 40D disposed between the side wall 12 and the upper end of the mass 40C. Control is interlocked with the shielding member 40A via the connecting member 40E.

The connecting member 40E that is pivotally supported by the support shaft 40D may be a single member, or may have a configuration in which a connecting member auxiliary member 42E is pivotally supported at one end thereof. One end of the connecting member 40E or the connecting member auxiliary member 42E connected thereto is rotatably connected to the rotating plate 44B, and the other end of the connecting member 40E or the connecting member auxiliary member 42E connected thereto is the upper end of the shielding member 40A. is connected with The rotating plate 44B is rotated by driving of a driving device 42B that constitutes the opening/closing device 40B, and a pair of limiters 46Bu and 46Bd that control the rotation of the rotating plate 44B are fixed to the driving device 42B. The limiters 46Bu and 46Bd are arranged so that the vertical movement distance of the shielding member 40A is equal to the opening/closing stroke of the gate 40 when the rotating plate 44B is rotated approximately half by driving the driving device 42B. A roof may be provided above the mass 40C to prevent golf balls from falling.

FIG. 5B shows a mode in which the transfer groove 30 is closed by the shielding member 40A of the gate 40. FIG. One end of the connecting member 40E on the opening/closing device 40B side is tilted upward with the support shaft 40D as a fulcrum, and the other end on the shielding member 40A side is tilted forward. If the rotating plate 44B for lowering the shielding member 40A rotates in the normal direction, the shielding member 40A can be moved upward by rotating the driving device 42B in the reverse direction. In addition, a flange 49A is formed in the vicinity of the end portion on the side wall 12 side of the rectangular tube-shaped housing 44A, and by bringing the flange 49A of the housing 44A into close contact with the side wall 12 near the notch 52, leakage of water is prevented. be able to.

The transfer groove B50 is connected to all the transfer grooves A30 provided in the pond facility 100, and the downstream end of the transfer groove B50 is connected to the water-sphere separating device 60, so that the golf balls in the transfer groove A30 are connected. can be transferred to the water-sphere separator 60 . The transfer groove B50 may be arranged separately in each transfer groove A30. For example, as shown in FIG. The structure may be continuous with all transfer grooves A30. In either mode, since the end of the transfer groove A30 is connected to the transfer groove B50 through the gate 40 provided in the side wall 12, a cutout for the gate 40 is formed in the corresponding portion of the side wall 12 and the transfer groove B50. A notch 52 is formed. The transfer groove B50 may be formed independently along the outer periphery of the side wall 12, but may be formed between the side wall 12 and the side wall 56 at substantially the same height as the side wall 12, which is provided outside the side wall 12 substantially parallel to the side wall 12. It may be provided. Forming the sidewalls 56 allows a portion thereof to be commonly used as the sidewalls of the mass 40C.

The transfer groove B50 can be composed of, for example, a commercially available U-shaped tube, like the transfer groove A30. Similarly to the transfer groove A30, the inner width and height of the transfer groove B50 along which the golf ball moves is 150 to 360 mm, preferably 240 to 400 mm. The transfer groove B50 also has a slope (θ3) descending toward the water-sphere separator 60, and the slope (θ3) is 0.1-5%, more preferably 0.2-3%.

Next, referring to FIG. 6, the bottom portion 14 is divided by providing the separation wall 16 in the water tank 10, and even if the inclination of the receiving portion 20, the transfer groove A30, and the transfer groove B50 of each bottom portion 14 is made gentle, and that the golf balls can be transferred to the water-sphere separator 60 in shallower water than conventional pond facilities.

In FIG. 6, the water tank 10 is a rectangle with rounded corners having a length (L1) of about 38.1 m and a width (W1) of 18 m. (W2) The shape is such that a concave portion of 8 m is formed. The bottom is divided into three parts: bottom 14A, bottom 14B, and bottom 14C. Transfer grooves A30 each having a width of 0.5 m are arranged in the center of bottom 14A, along the separation wall 16 of bottom 14B, and along the separation wall 16 of bottom 14C. It is The thickness of the separation wall 16 is 0.3 m, the length (L3) of the bottom portion 14A to the transfer groove A30 is 8 m, the length (L4) of the bottom portion 14B is 10 m, and the length (L5) of the bottom portion 14C is 10 m. For example, the transfer groove B50 has a length (L6) of 28.1 m.

The intersection point A (hereinafter referred to as point A) at the upper right corner where the extension lines of the side walls 12 of the water tank 10 intersect will be described below as the bottom reference point of the water tank. First, it is assumed that the receiving portion 20 of each bottom portion 14 has a slope (θ1) that descends toward the transfer groove A30, and the height of the side of the receiving portion 20 facing the transfer groove A30 is equal to point A. That is, point A indicates the highest position of the receiving portion 20 . The most upstream point of the transfer groove A30 of each bottom portion 14 is defined as a transfer groove A30T, and the most downstream point of the transfer groove A30 is defined as a transfer groove A30E. As shown in FIG. 6, the transfer grooves A30T of each bottom portion 14 are 30T(A), 30T(B) and 30T(C), respectively, and the transfer grooves A30E are respectively 30E(A), 30E(B) and 30E( C), the slope (θ1T) of the receiving portion 20 of each bottom portion 14 is set to 1.5%, the slope (θ2) of the transfer groove A30 is set to 1.21%, 0.8%, and 0.5%, respectively, and the transfer The slope (θ3) of the groove B50 is assumed to be 0.5%.

Taking the bottom portion 14C as an example, since the slope (θ1T) of the receiving portion 20 is 1.5%, 30T (C) sinks from point A by 0.15m (=10m×1.5%). In FIG. 6, (↓) indicates the sinking from point A. Since the slope (θ2) of the transfer groove A30 of the bottom portion 14C is 0.5%, 30E(C) sinks by 0.09m (=18m×0.5%) from 30T(C). That is, 30E(C) is located 0.24m (=0.15m+0.09m) deeper than point A.
Since the gradient (θ3) of the transfer groove B50 is 0.5%, the transfer groove B50 having a length of 28.1 m is 0.14 m (=28.1 m×0 .5%) sinks. 30E(C) is located 0.24 m below point A, so if the depth of transfer groove A30 and transfer groove B50 is 0.3 m, the bottom of the most downstream of transfer groove B50 is 0.24 m from point A. 68m (=0.24m+0.3m+0.14m) deep position. Since point A indicates the highest position of the receiving part 20, the pond facility 100 shown in FIG. It can be said that the bottom of the transfer groove B50 with a depth of 30 cm is buried in the position dug down to the bottom. In addition, in FIG. 6, since the shape of the water tank 10 has a concave portion, the point A is outside the water tank 10, but the position of the point A is not limited. This pond facility 100 can be used with water filled to a height of 0.1 m above the point A, and can be used as a penalty area even if the amount of water is small. In general, this pond facility 100 can be applied in the range of length (L1) 30-200m and width (W1) 15-50m.

The slope (θ1E) of the receiving portion (20) near 30E(C) of the bottom portion 14C is calculated to be 2.4% (=0.24m/10m). FIG. 6 also shows the slopes (θ1E) of 30E(A) and 30E(B) of the bottom portion 14A and the bottom portion 14B.

The pond facility 100 is provided with a water-ball separating device 60 for separating water transferred from the transfer groove B50 and collecting golf balls. The structure is not particularly limited as long as the water and the golf ball can be separated. The water-sphere separator 60 incorporates a circulating water pit in which the separated water can be stored, and the pond facility 100 includes such a circulating water pit separately from the water-sphere separator 60. is preferred. FIG. 7 shows a mode in which the water-ball separator 60 containing the circulating water pit 60A is connected to the water tank 10. As shown in FIG. The downstream end of the transfer groove B50 is connected to the water-sphere separator 60, the separated water is accumulated in the circulating water pit 60A, and the golf balls are accumulated in the ball pit 60B. The water in the circulating water pit 60A is fed by a pump 62 and circulated to the water tank 10 via a water supply pipe 64 .

In this water-sphere separator 60, the water discharged from the transfer groove B50 and the golf balls are introduced into the circulating water pit 60A through the conduit 61A. The conduit 61A may be pipe-shaped or gutter-shaped with its upper portion removed, as long as it can introduce water and golf balls from the transfer groove B50 into the circulating water pit 60A. Moreover, it is not limited to one, and may be configured by combining two or more. At the bottom of the conduit 61A, a through-hole is formed that does not allow the golf balls to fall, but allows water to fall. are arranged to be collected in the ball pit 60B. The golf balls in the ball pit 60B can be distributed to the bat via electric tools such as the ball distribution tube 62B and the belt conveyor 64B. Although the size of the circulating water pit 60A is not limited, it is preferable that the entire amount of water stored in any of the bottoms 14 can be stored. When circulating the water in the water tank 10, it is not easy to provide a circulating water pit for storing the entire amount of water to be filled in the water tank 10. However, since the bottoms 14 are separated by the separation walls 16, the gradients of the receiving parts 20, the transfer grooves A30, and the transfer grooves B50 can be set loosely. By appropriately setting the positions, it is possible to design so that the amount of water in each of the divided bottoms 14 is close to the same amount, so that the capacity of the circulating water pit 60A can also be set small.

The water stored in the circulating water pit 60A can be sucked up by the pump 62 and circulated through the water supply pipe 64 to the water storage tank 10 . The water supply pipe 64 communicates with an openable and closable water supply port 66 provided in the vicinity of the side wall 12, and the water supply port 66 communicates with the water supply through-hole 18 provided in the side wall 12 on the upstream side of the transfer groove A30. . When the water supply port 66 is open, the water in the circulating water pit 60A can be circulated from the water supply through-hole 18 to the water tank 10 through the transfer groove A30. By circulating and supplying water from the water supply through-hole 18, the golf ball in the transfer groove A30 can roll toward the gate 40 side.

The pond facility 100 may further include a general gate 70 between the transfer channel B50 and the water-sphere separator 60. FIG. Even if water leaks from any of the gates 40 of the bottom portion 14, the outflow of water can be suppressed by the general gate 70, and the water in the water tank 10 can be maintained at a predetermined amount. For this purpose, the general gate 70 is formed further downstream than any of the gates 40 formed in the transfer groove B50. For example, as shown in FIG. 7, it can be formed downstream of the gate 40 of the bottom portion 14A and adjacent to the side wall 56 formed on the outer circumference of the water tank 10. As shown in FIG.

The structure of the integrated gate 70 is not limited, but as an example, FIG. 8A shows a side view of the integrated gate 70, FIG. 8B shows a plan view thereof, and FIG. 8C shows a cross-sectional view taken along line BB of FIG. 8B. The general gate 70 is composed of a shielding member 70A that shields the water flow in the transfer groove B50, an opening/closing device 70B that controls the opening/closing of the shielding member 70A, and a mass 70C that houses the opening/closing device 70B. The transfer groove B50 is formed between the side wall 12 and the side wall 56, and a part of the side wall 56 constitutes the side wall of the mass 70C in common. For convenience of explanation, the side wall of the commonly used mask C will be described as the side wall 56 . The heights of the side walls 12 and 56 are both the same as the reference height.

Both ends of the shielding member 70A are vertically movably inserted into a pair of guide plates 58 provided on the walls of the side wall 12 and the side wall 56 disposed on both side surfaces of the transfer groove B50. A guide groove 59 is formed in the guide plate 58 to guide the vertical movement of the shielding member 70A. A support member 74A supported over the tops of the side walls 12 and 56 is fixed to the top of the side wall 12 and the side wall 56, and a pulley 76A is rotatably fixed to the support member 74A.

An opening/closing device 70B is housed in the mass 70C, and the opening/closing device 70B includes a driving device 72B, a transmission member for transmitting the drive of the driving device 72B, and a weight 78B. One end is connected to a weight 78B and the other end is connected to a support member 74A via a pulley 74B and a pulley 76B which are rotatably fixed to the side wall 56. As shown in FIG. When the drive device 72B starts to be driven, the rotation of the drive device 72B lowers the upper end of the weight 78B to the limiter 79Bd. The shielding member 70A connected to the other end of the rope R rises from the bottom to the top within the guide groove 59 provided in the guide plate 58, and the transfer groove B50 is released. When the driving device 72B is stopped, the shielding member 70A moves downward by the height H along the guide groove 59 of the guide plate 58 due to its own weight, and the gate 70 is closed. As the shielding member 70A descends, the weight 78B rises to the limiter 79Bu fixed above the limiter 79Bd by the height H. In FIG. 8A, by stopping the driving of the driving device 72B, the shielding member 70A moves downward along the guide groove 59 of the guide plate 58 by its own weight, and the bottom of the shielding member 70A comes into close contact with the bottom of the transfer groove B50. The mode which blocked the flow path of transfer groove|channel B50 is shown. A roof may be provided above the mass 70C to prevent golf balls from falling.

Next, how to use the pond facility 100 will be described.
First, the pond facility 100 is filled with water. Prior to filling with water, the gates 40 of the bottom 14 (A, B, C) and the general gate 70 are closed. The driving device 42B of the gate 40 is driven to rotate the rotating plate 44B up to the limiter 46Bu. As a result, the end of the connecting member 40E connected to the rotating plate 44B moves upward about the support shaft 40D, and the other end connected to the shielding member 40A moves downward against this movement, causing the lower end of the shielding member 40A to move downward. Contact with the bottom of the transfer groove A30. The gate 40 is thereby closed. In addition, in the general gate 70, by stopping the driving of the driving device 72B, the shielding member 70A is lowered by its own weight in the guide groove 59 provided in the guide plate 58, and the lower end of the shielding member 70A is moved to the transfer groove. Contact the bottom of the B50. After confirming that the gate 40 and the general gate 70 are closed, water is supplied to the water tank 10 .

A water-filled pond facility 100 can be used as a penalty area on a driving range. A golf ball flying over the pond facility 100 falls onto the receiving portion 20 of each bottom portion 14 . The impact caused by the falling golf ball is mitigated by the water filled in the water tank 10. - 特許庁A golf ball dropped onto the receiving portion 20 follows the gradient (θ1) of the receiving portion 20 and rolls along the rolling path 22 into the transfer groove A30 if the rolling path 22 is provided. A golf ball may drop directly into the transfer groove A30 or the transfer groove B50 without passing through the receiving portion 20 .

Next, a method of collecting golf balls from the water tank 10 will be described.
If the general gate 70 is provided, the general gate 70 is opened. The driving device 72B provided in the mass 70C is driven to lower the weight 78B to the limiter 79Bd through the transmission members provided on the pulleys 74B and 76B. As the weight 78B descends, the rope R finally moves the shielding member 70A upward along the guide grooves 59 of the pair of guide plates 58, and the general gate 70 is released. When the driving device 72B stops driving, the shielding member 70A descends to close the general gate 70. As shown in FIG. As a result, the water from the top surface of the water filled in the water tank 10 to the top of the separation wall 16 that divides the bottom 14 (A, B, . . . ) is discharged. In addition, as will be described later, when a storage tank (not shown) is provided in the lower part of the water storage tank 10 separately from the water-sphere separator 60, the bottom 14 ( A, B...) may directly introduce water into the reservoir.

Each gate 40 on the bottom 14 is then opened in turn. The driving device 40B arranged in the mass 40C is driven to rotate the rotating plate 44B up to the limiter 46Bd. The connecting member 40E connected to the rotating plate 44B moves downward about the support shaft 40D, and along with this, the other end connected to the shielding member 40A rises, and the lower end of the shielding member 40A rises from the bottom of the transfer groove A30. The gate 40 is released by leaving. The water in the bottom portion 14 (A, B, C) moves from the gate 40 through the notch 52 to the transfer groove B50, and as this water moves, the golf ball remaining in the receiving portion 20 also changes the slope (θ1) of the receiving portion 20. and along the slope (θ1) of the rolling path 22 to the transfer groove A30. The golf ball in the transfer groove A30 moves toward the gate 40 along the slope (θ2) of the transfer groove A30 and the water flow, and then passes through the notch 52 and moves to the transfer groove B50.

The golf ball transferred to the transfer groove B50 is moved toward the general gate 70 by the slope (θ3) of the transfer groove B50 and the water flow from the gate 40, and further passes through the general gate 70 to the water-sphere separator 60. do. The water in the transfer groove B50 and the golf balls pass through the conducting path 61A of the water-ball separator 60, and the water is collected in the circulating water pit 60A and the golf balls are collected in the ball pit 60B. The water in the circulating water pit 60A can also be sucked up by the pump 62 and circulated to the water tank 10 via the water supply pipe 64 through the water supply through hole 18 provided in the side wall 12 . Since the water supply through-hole 18 is formed on the upstream side of the transfer groove A30, the circulating supply of water can help the golf ball to move in the transfer groove A30 toward the gate 40 side.

Each bottom portion 14 separated by the separation wall 16 may be operated to recover the golf ball from any of the bottom portions 14, but the gate 40 of each bottom portion 14 may be opened without opening the gate 40 of each bottom portion 14 at once. 40 is opened, and after the recovery of the golf balls on the bottom portion 14 is completed, the golf balls on the other bottom portions 14 are preferably discharged one by one.
For example, the general gate 70 and the gate 40 of the bottom portion 14C are opened to transfer the golf balls together with the water flow to the water-sphere separator 60, and the water collected in the circulating water pit 60A is transferred to the bottom portion 14C through the water supply through-hole 18. By circulating to the upstream side of the grooves A30, the golf balls remaining in the transfer grooves A30 of the bottom portion 14C can be easily recovered. Thereafter, the gate 40 of the bottom portion 14B or the bottom portion 14A is opened in the same manner as in the bottom portion 14C, the golf ball is moved to the water-ball separator 60 in the same manner, and the through hole for water supply is opened in the same manner as in the bottom portion 14C. 18 to the upstream side of the transfer groove A30 of the bottom portion 14B or the bottom portion 14A. The golf balls collected in the ball pit 60B are sequentially transferred to the batting side using a belt conveyor or the like. In the pond facility 100, the bottom 14 of the water tank 10 is divided into a plurality of parts, so that the golf balls in the bottom 14 can be collected from each bottom 14. FIG. The rolling of the golf balls is hindered by mutual contact, but since each bottom portion 14 can be treated, the golf balls can smoothly roll in the transfer grooves A30 and B50. Each bottom portion 14 divided by the partition wall 16 has the characteristic that the golf ball can be efficiently discharged out of the water tank 10 even if the inclination (θ1) of the receiving portion is as low as 1 to 7%.

In addition, when the water-sphere separator 60 constituting the pond facility 100 of the present invention incorporates a circulating water pit 60A capable of storing the separated water, the capacity of the water tank 10 and the circulating water pit 60A It is preferred that the volumes of the As a result, waste water after use can be stored and reused. In addition, in the present invention, a storage tank may be provided separately from the circulating water pit 60A for storing water from the surface of the water introduced into the water storage tank 10 to the top of the separation wall 16 when the water is drained. A room can be provided under the water tank 10 or under the receiving part 20 to form such a water tank. Alternatively, an island may be provided in the water tank 10, and the lower part of the island may be used as the water tank. In the case of storing at the bottom of the water tank 10, the area of the water tank 10 or less is sufficient. The water in the storage tank can be circulated to the storage tank 10 again by a pump or the like for use.
On the other hand, the capacity of the circulating water pit 60A is a capacity capable of storing water below the top of the separation wall 16 of any of the bottoms 14 (A, B...) during drainage. In the present invention, the water tank 10 is divided by the partition wall 16 into two or more bottom portions 14, and when collecting the golf balls, the golf balls are collected for each bottom portion 14 (A, B, . . . ). can be done. Therefore, the circulating water pit 60A should be able to store the maximum amount of water in any one of the bottoms 14 (A, B, . . . ), which is the amount of water below the separation wall 16 . For example, if the amount of water stored below the separation wall 16 of the bottom 14A partitioned by the separation wall 16 is the largest among the divided bottoms 14, the circulating water pit 60A should be able to store this amount of water. good. As a result, the capacity of the circulating water pit 60A can be reduced. In addition, in the present invention, the capacity of the circulating water pit 60A can be adjusted by the arrangement position and the number of the separation walls 16 arranged.

FIG. 9 shows an example of a golf driving range in which the pond facility 100 of the present invention is installed. Although the pond facility 100 includes a water-ball separator 60, the pond facility 100 of the present invention can be constructed using a water-flow ball recovery system installed at a golf driving range. For example, at least the bottom 14 has a water tank 10 divided into two or more by a separation wall 16, and the bottom 14 is provided with a water tank 10 having a receiving part 20, a transfer groove A30, a gate 40, etc., and water from the transfer groove A30 is provided. and the golf ball are ejected from the gate 40.例文帳に追加is introduced into the transfer groove B50 with the golf ball and water discharged from the gate 40, and the water and the golf ball are separated by the water-ball separation function of the water-jet ball recovery system. Separate the ball. An example of such a mode is shown in FIG. In FIG. 9, U, U1, U2, and U3 are U-shaped tubes for collecting balls that constitute a water-type ball collecting system, and some of them function as transfer grooves B50. In FIG. 9, in addition to a pond facility 100 functioning as a penalty area, bunkers B filled with sand, target greens G, simulated trees T, and ball-collecting U-shaped tubes U are arranged on the undulating ground. there is The ball collecting U-shaped tube U1 is located at a slightly elevated place, and the ball collecting U-shaped tube U2 and ball collecting U-shaped tube U3 are arranged so as to cross under the bottom of the pond facility 100 and flow into the ball collecting U-shaped tube U. is designed to In the pond facility 100 of the present invention, since the water tank 10 is shallow such that the water depth of the bottom part 14 of the water tank 10 can be set to 0.25 m to 0.55 m, other piping and other arrangements can be easily made at the golf driving range. becomes.
