Definitions

  • the recreational equipment for ski jumping for snow sports in the prior art has an approach portion and a landing portion.
  • the approach portion utilizes a natural terrain such as slopes of hills and mountains, or utilizes an artificial slope formed by scaffolding by laying run-up mat for skiing on the artificial slope.
  • the recreational equipment employing the water jumping has a problem to be solved that the safety for users is not always highly secured because physical shock by sudden change of temperature and shock by the water pressure in collision at the moment of landing because the landing portion is filled with water in the sea or pools.
  • the use period of the recreational equipment is limited to summer season because of using the water surface for landing, users can not play during autumn season to winter even if they want to practice jumping.
  • protectors for protecting users must play or practice by wearing a protector or an impact resistance suits, such as life jackets and wetsuits.
  • Such protector and suits gives players different feelings from the real feelings which can obtain in the real ski jumping.
  • the plate members which vertical width is more than 5m are jointed by the relative angle 5 degrees
  • the plate members which vertical width is less than 1m are jointed by the relative angle 1 degree to 3 degrees for adjusting these joint angle in order to make the pseudo-curved structure by the connection of the plate members becomes similar to the ski jump curved structure.
  • the angle is within 5 degrees per 5m, that is, the change rate is less than 1 degree per 1m. According to the many years of research and study by the inventor, if the change rate is more than 1 degree per 1m, the player feels the angle change distinguishably. In addition, the angle change is too much, the player feels the bumping distinguishably, but the angle change is less than 3 degrees per 1m, the player does not feel bumping fluctuation.
  • Fig. 3 (b) shows the example of what is called "spray cooling system" in which the external sprinklers is installed on the outside of the edge of the approach portion 110 instead of installing the sprinkler 118 under the in-run face.
  • the cooling water is sprayed from the side in order to slide on the artificial slope easier.
  • the area where the cooling water is sprayed by such external sprinkler is extended in a fan shape, so it is impossible to concentrate the cooling water efficiently on the in-run face 116.
  • the angle of plate member 114 is changeable by changing the height.
  • the angle of plate member 114 is changeable to adjust each height, H1, H2, H3, H4 and H5 by jacking up.
  • the length of the plate member 114 of the edge 117 for takeoff is more than 75cm up to 1m. Because the ski boards stride over more than 2 joints between plate member 114 at the same time because the length of the ski boards is about from 1m50cm to 2m in usual. If the number of the joints connecting between plate member 114 that the ski boards stride over is more than 2 pieces, the player can focus on takeoff upward because the ratio of the vector change in upward direction increases.
  • the angle of the plate member 114 of the takeoff portion 113 is changeable by changing its height.
  • the angle of the plate member 114 is changeable to adjust each height H6, H7, H8, H9, H10 and H11 by jacking up.
  • the table portion 120 is explained below. As shown in Fig.6 , the upper end of the landing portion is gently sloped, but does not have the horizontal table portion as the prior art.
  • the table portion of the prior art is provided simply as horizontal table, which is overpass physical space in the case that ski jumping is taken off by the predetermined initial rate.
  • the slope of the landing portion is provided after such nord portion. Therefore, in the case of failure jumping, for example, the players tumble in approach portion 110 and fall forward, they can be involved in accidents to fall directly on such table portion.
  • the nose of the table portion 120 is lift up to the vicinity of the height of the end of the approach portion 110 to reduce the gap and distribute the falling impact as showing in Fig. 1 .
  • the partition membrane 133 has a structure which passes the air through it, if a landing impact is applied to the air mat as shown in Fig. 7 , the inside air in the vicinity of the center portion of the air mat flows over to the vicinity of the cylindrical tube 137 by passing through the partition membrane 133 cross and oblique direction.
  • the recreational equipment for ski jumping 100 comprises the landing lower portion 140, the deceleration portion 150 and the stopper 160.
  • the deceleration portion 150 is provided in front of the landing bottom portion 140 to ensure decelerating, this may have a gradual upward slope, otherwise be nearly horizontal.
  • the forming direction of the partition membrane 133 in the air mat may change to the crossing direction as shown in Fig. 6 in order to enhance the deceleration.
  • the partition membrane 133 is installed as connecting the inner wall of top surface and the inner wall of bottom surface of the air mat, so uneven bump and groove are formed on the surface of the air mat. If the forming direction of partition membrane 133 in the air mat is crossing direction, the cylindrical tube 137 is arrayed in horizontal direction so some bumps appear on the surface of the deceleration portion 150.
  • the bumps and grooves may be formed on the cover sheet 151. In this configuration, the bumps and grooves are arrayed on the sliding direction and those give a large resistance against ski boards. Thus, deceleration effect is obtained by passing the bumps and the grooves in the ski sliding.
