Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a fountain maze facility which forms a passage divided by a fountain and is used for a maze game.

[0002]

2. Description of the Related Art A labyrinth facility is constructed in which passages divided by board fences are formed, and the passages are made into dead ends, dead ends, or communicated with each other to make a maze. Have been served. A technique disclosed in Japanese Patent Laid-Open No. 63-275364 has been proposed as a technique for partitioning and forming such a maze with a fountain. This technique consists of a fountain nozzle fixed to a substrate and a net as a splash prevention device that prevents the jet water from splashing when the jet water from the fountain nozzle falls on the ground.

However, in the above-mentioned prior art, since this net is exposed between the walking part of the maze and the jetted water, there is a feeling of strangeness, and above all, it is preferable in a maze-like amusement facility for the sake of aesthetics. is not. Further, although a net is laid in the falling part of the jet water, the net is installed only in a very limited part near the fountain nozzle, and no consideration is given to drainage of the passage itself.

Therefore, a grating is laid in the passage, an artificial grass is laid on the grating, and drainage grooves such as gutters are provided under the grating, which is a conventional technique excellent in drainage function and aesthetics. The one described in Japanese Patent No. 81992 is known. Further, instead of the grating, a water-permeable groove lid is provided, and a large number of holes are provided on the bottom surface of the concave body of the groove lid.
The conventional technique described in Japanese Patent No. 289 is known.

[0005]

[Problems to be Solved by the Invention]
When the grating described in Japanese Patent No. 3-81992 is applied to a fountain maze facility, if the person wears high heels on the grating and walks, the heel of the high heel is caught and the heel is damaged or the foot is damaged. There is a risk of falling and injuring yourself. Further, when the spacing between the gratings is a little wide, the artificial turf placed on the grating becomes dented into a corrugated shape and becomes unsightly while many people walk.

When the groove cover described in Japanese Utility Model Laid-Open No. 64-53289 is applied to a fountain maze facility, a large number of people walk on it in the fountain maze facility. There is a problem in strength. That is, the groove lid is bent due to the load of a large number of people and becomes unsightly, which is not preferable in a game facility such as a maze for the purpose of aesthetics. Also, since the groove lid bends to reduce the area of the hole and the water jetted from the fountain nozzle comes into contact with the groove lid, the jetted water may not be able to go straight up, and the player's clothes may be wet. The function as a fountain maze facility cannot be fully fulfilled.

Therefore, the present invention provides a fountain maze facility which can prevent slipping of water and prevent slipping or pinching of heels of high heels, that is, safety is ensured and aesthetics and strength are provided. The purpose is to provide.

In order to solve the above-mentioned problems, the present invention provides a jet water supply pipe connected to a pressurized water source and connected to a pool-shaped water receiving tank. A fountain nozzle is connected, a control valve is installed between the supply pipe and the fountain nozzle, a grating is installed over the entire surface of the water receiving tank, and multiple perforated plates with numerous holes are continuously formed on this grating. Then, the perforated plate was covered with water-permeable artificial turf to form a labyrinth divided by the water jetted from the fountain nozzle through the artificial turf.

Further, the tip of the fountain nozzle is made to face the hole of the perforated plate. Alternatively, an opening different from the hole is provided in the perforated plate, and a fountain nozzle is exposed to this opening, or a gap is provided at the joint between the perforated plates, and the fountain nozzle is exposed to this gap.

[0010]

According to the above means, the pool-like water receiving tank has a three-layer structure including the grating, the perforated plate having a large number of holes, and the water-permeable artificial grass, and the fountain nozzle in the water receiving tank is The maze is divided by ejecting water from artificial turf.
Further, the jetted water that falls falls into the water receiving tank through the artificial grass, the holes of the perforated plate, and the grating, and the splashed water that falls is not collected around the maze.

Further, the tip of the fountain nozzle may face the hole of the perforated plate, or an opening different from the hole may be provided in the perforated plate and the fountain nozzle may face this opening, or the perforated plates may be connected to each other. Since a gap is provided at the joint and the fountain nozzle is exposed to this gap, the spouted water spouts straight without hitting the perforated plate.

Discharges the jetted water falling on the artificial grass 18 ... into the water receiving tank 2.

FIGS. 4 and 5 are views of the artificial turf.
The substrate 18a of No. 8 is formed in a lattice shape, and small rectangular drainage holes 18b ... Are provided on the entire surface. For example, turf members 18d are brushed or planted on the bone portions 18c between the drain holes 18b. The turf members 18d are laid down so as to cover the drainage holes 18b from above so that the grid-shaped drainage holes 18b are hidden so that the lawn is formed on one surface without any discomfort.

The holes 17 of the perforated plate 16 and the drain holes 18b of the artificial turf 18 are preferably a combination of different sizes, shapes, pitches and the like. In this case, there is a part where one hole closes the other hole, but since many holes 17 and 18b are provided, there is also a part where the holes coincide with each other and the overall balance can be achieved, so the jetted water that has fallen can be quickly Can be discharged to. In actual construction, it is sufficient to lay the artificial turf 18 on the perforated plate 16 and the construction does not take time. Further, even if the artificial turf 18 is displaced due to the walk of the player, it is possible to deal with it. On the other hand, there is no problem even if the sizes, shapes, pitches, etc. of the holes 17 and 18b are the same, and in this case, since it is necessary to lay the holes so that they match each other at the time of construction, it takes time, The area of drainage due to the communication between the holes becomes larger.

The above-mentioned fountain nozzles 9 ... Face the artificial turf 18 constructed as described above through the holes 17 ...
The spouting water fountain spouts 19 ... Are provided in a portion of the artificial grass 18 facing the fountain nozzles 9. The fountain nozzles 9 ... Are provided so as to open at the water discharge ports 19 ... And slightly below the level of the artificial grass 18.

6 and 7 are views of the fountain nozzle. The fountain nozzle 9 is formed by narrowing the upper portion of the cylindrical body 9a to form a small-diameter nozzle portion 9b having a predetermined length. As shown in FIG. 7, a round bar is connected in a cross shape and a rectifying member 9c is installed at an intermediate portion of the small diameter nozzle portion 9b. As a result, the pressurized water flowing from the header pipe 8 into the large-diameter cylindrical main body 9a is prevented from flowing into the small-diameter nozzle portion 9
When it is squeezed by b and is jetted vertically upward with increasing flow velocity,
Since air bubbles are also generated by being rectified by the rectifying member 9c and colliding with the rectifying member 9c, the jetted water is formed like a tree as shown in FIG. 9, and the bubbles are also formed in the jetted water.

As described above, the four fountain nozzles 9 are arranged in parallel at a predetermined interval in the embodiment as described above, so the ejected water arranged in parallel has a form like a wall or a tree path. Therefore, a large number of maze elements 10 ... In which four fountain nozzles 9 ...
By selecting and causing the fountain, a passage, that is, a maze, is formed between the maze elements.

FIG. 8 is a view showing an example of forming a maze. A maze element 10 ... Is selected to form a dead end portion b by a fountain wall and a communication passage portion c, and a passage from an inlet d to an outlet e according to an arrow. Are formed, and many side roads f ... The above maze is arbitrarily changed by selecting the fountains of the above-mentioned maze elements 10 ... Therefore, by changing the fountain pattern every day, every few days, or even every week, it is always fresh and never mastered. A maze can be formed.

In the above, the controller 12 controls the opening and closing of each control valve 11 so that the water pressurized by the pump 5 is ejected from the open labyrinth element 10 ..., thereby forming the fountain labyrinth as described above. The spouted water falls directly to the spouting nozzles 9 ... Or around the spouting nozzles 9 or flows slightly by the wind and scatters and falls around. By the way, a fountain opening is formed in the passage,
Although the spouted water falls to the end of the passage of the artificial grass 18, the artificial grass 1
Since 8 has the water drain holes 18b ... And has water permeability as described above, it drops as it is and is recovered from the grating 15 through the hole 17 of the perforated plate 16 through the water receiving tank 2 to the storage tank 4.

As described above, the artificial turf 18 is water-permeable throughout the passage even if the jetted water does not fall to the peripheral portion of the fountain nozzle 9 ...
Therefore, it does not fall into the water receiving tank 2 and remain on the passage. Therefore, it is possible to prevent a situation where the passage gets wet and as a result, the person walks and slips, and it is possible to walk safely while playing. Further, the dropped water is pumped up again from the storage tank 4, supplied as jetted water, and circulated.
Since the jetted water falls into the passage and is collected, there is a risk that it may contain mud and the like. Therefore, a filter (not shown) is provided upstream of the pump 5.

The fountain maze facility of FIG. 1 shows an example in which a windbreak wall 20 is partially erected as shown in FIG. When the wind is strong, the jetted water is washed away by the wind, and when the player walks, the clothing may be wet with splashes, or in some cases the jetted water may be slanted. is there. Under such a meteorological condition, a windbreak wall 20 is erected on the windward side of the fountain nozzles 9 of the maze element 10.

In the embodiment, the angle member 21 is placed on the artificial grass 18.
