Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an end ramp for a water slide, and is particularly characterized in that the end ramp is formed in a fan-like shape, and the trajectory of the person sliding down the ramp is not constant. be.

A water slide is a kind of slide for playing in the water, and has water flowing down the sliding surface to reduce frictional resistance.The end ramp is set toward the water surface of a pool, etc., and is as described above. As the frictional resistance of the sliding surface is small, there is no need to deal with the generation of frictional heat, and the end ramp faces the water surface, so there is no need to reduce the speed of the descent in this part, so it is possible to make the course long and It can be made complex and has a sense of speed, making it a highly interesting toy for older children.

By the way, as mentioned above, the end ramp of a water slide faces the water surface, and at the end of the slide it plunges into the water from here, but since the downhill course is constant, it is natural that the end ramp faces the water surface from here. is also almost constant.

Therefore, when two or more people ski down in succession, there is a risk that the person who plunged into the water first will fall on top of the person who is skiing later, resulting in a collision.

The present invention solves the above-mentioned problems with conventional water slides. Focusing on the fact that the speed of descent varies slightly depending on the person, the present invention has the end ramp spread out in a fan shape and the sliding surface tilted to one side. This makes the downhill trajectory on the end ramp unstable and eliminates the possibility of a collision occurring.

The present invention will be specifically described below based on illustrated embodiments.

In the figure, numeral 1 is an end lamp, and 2 is a water surface.
This is basically the same as the end ramp of this type of water slide, and forms the end part of the water slide. It consists of a sliding surface 3 and a side wall 4, and extends from the top to the bottom in the figure. It used to slope gently downward, with the end facing the water surface 2, and water flowing down onto the sliding surface 3.

As shown in FIG. 1, this end ramp 1 is formed in a fan-like shape toward the end, and the upper part of the end ramp is inclined to one side except for the end portion of the sliding surface.

As described above, by forming the sliding surface 3 so as to be inclined to one side, the sliding trajectory can be varied depending on the difference in the speed of the person sliding down the surface.
That is, this will be explained based on FIG. In this figure, the downhill direction of the sliding surface 3 is x, the downward slope direction is y, and a person is sliding down on this at a speed of v,
If the direction of gravity is G, then a force f acts on this person to try to descend in the y direction, so the direction of this person's descent eventually changes to P. Here, the variation amount θ in the downhill direction increases as the downhill speed v decreases. Therefore, the lower the downhill speed is, the more the downhill trajectory s is biased toward the valley side, and as a result, the position at which the vehicle plunges into the water surface from the end of the end ramp 1 differs depending on the difference in downhill speed.

Of course, in the above, it is also desirable to artificially increase the amount of variation in the downhill trajectory s, for example, by providing a water fountain 5 at a suitable location on the mountain side of the sliding surface 3 and spouting water from there toward the valley side. One method is to create a flow of water toward the valley side on the sliding surface.
Alternatively, one method is to provide unevenness on the sliding surface 3 to change the direction and speed of the slide.

As described in detail above, the present invention is formed by expanding the sliding surface of the end ramp of a water slide into a fan shape,
It is formed by tilting the upper part to one side except for the end part, and the lower the speed of the person skating on it, the more the direction of the slope will change, so the trajectory of the slope will differ depending on the speed of the slope. As a result, the possibility that the next person sliding down the slope will collide with the person who plunged into the water first is significantly reduced, and accidents are prevented from occurring.
