Description

Landing slope

Technical Field

The utility model relates to the field of sports facilities, in particular to two sports projects with 'sports leap' of skiing and kite surfing, and relates to a landing slope.

Background

Skiing is a very popular sport for people. However, in the past, people only need to rely on natural snowfall or artificial snow for skiing in short and cold winter. In order to make skiing movement not limited by natural seasons, plastic snow is developed by those skilled in the art for four seasons skiing, wherein the plastic snow is called as 'dry snow', and the slide made of 'dry snow' is called as 'dry snow slide'.

The true snow runner includes a taxiway and a landing slope. Correspondingly, "dry snow runner" also includes "dry snow runner" and "dry snow landing slope".

The person does not have wings and never stops the craving for flight. Therefore, people have devised "sports leaps" in many sports, especially in both skiing and kite surfing. In this case, the user can achieve a cool flight by using his own technology and strength. It is well known that human "flying" is so rare that it is very cool and has excellent ornamental value. However, the human being can complete the sport project of 'sport leap' on the landing slope without the wing, which is very dangerous, and often causes serious sport injury and even disability.

Sports injuries bring people too much trouble, pain and anxiety:

1. the pain and even disability are brought to leapfrog people, and the original purpose of exercise and body building is violated;

2. inhibit the popularization and development of 'sports leap';

3. the training process of 'motion leap' is forced to be slow, and the international level is difficult to be quickly overtaken;

4. the industry decision maker and stadium operators are frightened.

Therefore, it is important to design a landing slope with high technological content for leapfrog without wings and forced take-off, wherein the most critical link is the landing slope. As is known, a complete set of "motion jumps" is divided into 5 steps:

1. accelerating sliding;

2. lifting off;

3. flying in the air;

4. accurate landing;

5. keep sliding.

The inventor considers that a landing slope with a high technological content of diving platform can meet the following 5 great needs:

1. safety: allowing leapers to try high-difficulty new actions without any trouble, and ensuring the safety and no damage of each landing;

2. high simulation: leaps still use skiing equipment and skiing technology for real snow or equipment and skiing technology for billows to "fly" requiring landing slopes to provide more realistic taxiing performance, such as: the cutting edge, the sliding, the braking and the buffering are similar to the skiing or the bodywave field, so that the skiing or the bodywave field can be used for replacing true snow to train and match;

3. the leap is complete: completing a complete set of motion leap actions, wherein 5 steps are indispensable;

4. the temperature and humidity are not limited by seasons, regions and regions;

5. environmental protection: low cost.

The existing dry snow landing slope is realized by adopting an air cushion water spraying technology. The air cushion water spraying is characterized in that the air cushion is inflated and arranged on a slope below the diving platform, and then the air cushion is continuously and uniformly sprayed with water to assist sliding. The air cushion water spraying technology can ensure the safety of leaps, but the air cushion can not provide cutting edge sliding. Therefore, 100% of leaps are all over lying, so that the "sports leap" cannot be practiced in the last step: keep sliding. Another disadvantage of the "air cushion water spray" is that: the landing technology can only be used in midsummer or severe winter, because water spray thoroughly wets the leapfrog, the wetted leapfrog cannot resist the cold in spring and autumn, and a great deal of physical energy is consumed by the leapfrog. The large-area continuous inflation, deflation and continuous and uniform water spraying all require a large amount of water and electricity consumption and manual real-time control.

In view of the above related art, the inventors consider that the existing landing slopes have drawbacks that are seasonally constrained, have low safety, and cannot satisfy the requirement of a leap person to complete a complete "sports leap" action.
