Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a method for forming a sloped sliding surface for use in games and the like, and to a grass-like substance used on the sloped sliding surface.

BACKGROUND OF THE INVENTION 2. Description of the Related Art Slopes such as river banks and other slopes overgrown with weeds are perfect playgrounds for children to slide down and play. If you try to obtain this artificially, the slope angle of the sliding surface will be 5 to 20 degrees in order not to impair the playability and to ensure safety when landing.
degree is suitable.

Problem to be Solved by the Invention However, if a plastic grass-like material that can withstand repeated use is planted on the sliding surface, the friction coefficient of the sliding surface will be 0.
．． When the speed is around 6, the sliding speed is slow, causing a problem that the playability is impaired.

The present invention aims to provide a method for forming a sloped sliding surface that improves the above-mentioned problems, and a plastic grass-like material to be planted on the sliding surface.

Means and operation for solving the problem By planting plastic grass-like materials on the sloped sliding surface and flowing water on the grass-like materials to reduce the coefficient of friction of the sliding surface, A method for forming a sloped sliding surface characterized by obtaining a sliding surface suitable for sliding play, and a method for forming a sloped sliding surface, which is characterized by planting piles on a waterproof sheet-like material to improve water retention and sliding performance. Grass.

Embodiment An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the overall shape of an amusement facility having a plurality of sliding surfaces 1, each of which is supported by a pedestal 2 shown in FIGS. At the top of the pedestal 2, there is installed a water tank 3 for storing water, and a water discharge means 4 such as a waterfall for uniformly discharging the water in the tank 3 to the sliding surface 16. In order to enhance the playability, artificial rocks 5 and the like are placed along the way, and stairs 6 are installed on both sides of each sliding surface 1, so that it is easy to climb the sliding surface 1 to the top of the sliding surface 1 after a fall. You can reach it by climbing.

The slope of the sliding surface 1 is in the range of 5 to 20', and a plastic screen 7 is planted on the sliding surface 1. This screen 7 is made of a resin such as polyethylene, polypropylene, vinylidene chloride, or nylon, and when used as a ski resort in the winter, the interfacial tension should be I 5 clines/cm to 4 due to attached water.
It is desirable to use plastics with a performance of 0 dyng/cm.

As shown in Fig. 4, the curtain 7 is made by collecting 8 pieces with a pile width of 0.5 mm on a plastic sheet g and planting them at a pitch of 3.5 μ. If the apparent depth of the water flowing into 1 is 15W, the pile length is 12
~15 iu. In addition, when artificial snow is made to fall on the sliding surface 1 in winter and used as a ski or sledding area, the artificial snow accumulated on the sliding surface 1 freezes on the curtain 7 and becomes a roller shape, which further reduces the friction on the sliding surface 1. This will reduce the amount of water and provide a good sliding surface. The next grass-like material 7 and the next sheet-like material 8 are made of glass, which has a high heat insulation effect, reduces loss due to ice melting, and is suitable for skiing and sledding even with a small amount of snowfall. surface will be obtained.

By the way, the temperature is -5℃, the length of the sliding surface is 29m1, the slope angle is ff I
When an adult with 60 KP skied down a 5.5 m high slope with skis, a speed of l (, m/ygt) was obtained. This is 1 .6 times faster.

The sliding surface 1 obtained as described above constantly drops water uniformly to form a layer of water at a constant depth on the sheet-like object δ, on which children, etc. slide down. The curtain 7 is removed by flowing.

The friction coefficient must be less than 0.1, so that the inclination angle is 1.
5°, height is 5.5m, terminal velocity is 5m 2m
/z a e and a sufficient sliding speed can be obtained. In order to obtain this terminal velocity by dropping only water onto the sliding surface without the curtain 7, a large amount of water of 3.45 to 3.5 t/in is required. By dropping water onto 7, a sufficient sliding speed can be obtained with a small amount of water.

Effects of the Invention As described in detail above, this invention attempts to obtain a sliding surface that is optimal for playing by dropping water uniformly onto a sliding surface on which plastic undergrowth is planted, and by reducing the coefficient of friction of the sliding surface. Since it is small at less than 0.1, it is possible to charge the submerged ice with a small slope. In addition, by using the curtain and water in combination, the coefficient of friction can be significantly reduced with less water consumption, and since the curtain is made of plastic, it will not wear out even after long periods of use, so it can be easily maintained. You can also save on expenses.
