Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a downhill device used in a large downhill device installed in a leisure facility.

(Prior art) A conventional large-scale downhill slide device for a leisure facility has a plurality of upright columns, and these columns serve as pedestals for sliding downhill in the form of an open channel or a culvert that gently rotates from above to below. It is formed by providing a stand. The slide has a gentle slope, that is,
The average inclination angle is 5 to 10 degrees, and in order to improve the downhill performance, water is supplied from the entrance of the upper slide to the exit of the lower slide, so that skiers can ride the water current. has been done. These large-scale downhill devices include, for example, the application made by the applicant in 1983.
-There is a device called No. 130795. In conventional systems, the water directly washes down the skiers, or the supplied water reduces the frictional resistance on the contact surface with the skiers, making them slide. Therefore, the use of large skiing equipment is limited to the summer and is not available at other times of the year. was not available. Furthermore, there is no downhill equipment that does not use water and is used outside of summer, and it is not used in large downhill equipment.

(Problems to be solved by the invention) In conventional large-scale downhill devices, the slope of the downhill platform is made small and the slope is configured to form a gentle descending line. There are inherent problems in that it is not possible to ski downhill, and that skiers can only use equipment with a pool during the summer when they can get wet.

In this case, at any time without using water,
In order to use a large gliding device formed on a gentle slope, the coefficient of friction (μ) with the gliding surface must be 0.1.
In other words, the downhill speed must be between 2 meters per second and 6 meters per second, and it must also be highly safe.

(Means for solving the problem) In this invention, the seat 1 is formed into a rectangular pine-like shape having a long axis in the direction of travel, and the seat 1 has an obtuse angle with the seat 1 at the rear end in the direction of travel. A sliding pedestal 4 consisting of a backrest 2 formed in the shape of a shape, two fixing bands 3 provided spaced apart on both side edges along the long axis of the seat 1, and a sliding pedestal 4 having the same planar shape as the back surface of the sliding pedestal 4. A sliding pedestal 4 formed into a flat plate shape with
A base 5 to be fixed to the back surface of the base 5, a large number of small-diameter rod-shaped fixing protrusions 6 protruding from the plane of the base 5 at the same height and integrally formed with the base 5, and the fixing protrusions 6. The ice coating 7 of the fixing protrusion 6 is formed in such a way that the ice coating 7 of the fixing protrusion 6 contacts the sliding surface and slides down. The object of the present invention is to provide a downhill tool in a large downhill device that solves the problems.

(Example) This invention will be explained in detail based on the illustrated example. Figure 1 is a perspective view of the downhill gear according to this invention, and Figure 2 is an explanatory view seen from the front.
is a seat, 2 is a backrest, 3 is a fixing band, and 4 is a sliding base. The sliding base 4 is formed by providing a seat 1, a backrest 2, and a fixing band 3. The seat 1 is made of hard plastic material or FRP material made by laminating glass fiber and synthetic resin material. Further, the seat 1 is formed into a rectangular planar shape having a long axis in the direction of travel, and two fixing bands 3 are provided on both side edges along the long axis at a distance from each other in the long axis direction. The fixing band 3 is provided at a position where one side tightens the thigh area of the downhill rider and the other side tightens the waist area. Further, a backrest 2 formed at an obtuse angle with the seat 1 and rising up on an inclination is integrally provided at the rear end in the direction of travel. Further, the seat 1 is provided with a mat 8 made of urethane material and having a thickness of 10 mm to 50 mm, which is formed in the same planar shape as the seat 1.

Further, as shown in the cross-sectional explanatory diagram of FIG. Provided in close contact with the bottom surface of the The base 5 is made of a synthetic resin material such as polyethylene material, nylon material, or cotton material twisted into a thread shape. Furthermore, a small diameter rod-shaped fixing projection 6 is provided on the entire lower surface of the base 5. Fixing protrusion 6
One side of a thin rod shape is formed integrally with the thick part of the base 5, and the other side provided with the branch part is formed to protrude from the plane of the base 5. In this case, the fixing protrusion 6 is formed with a diameter of 0.5 mm to 3 mm,
It is desirable that the protruding height of the base 5 from the plane is in the range of 0.5 cm to 1 cm, and the height is the same as a whole. Further, the fixing protrusions 6 are provided on the base 5 at a density of 3 to 15 protrusions per square centimeter. Ice grains 9 are provided on the protruding portion of the fixing projection 6 from the base 5. ice grains 9
The particles are formed to have a diameter of about 400 microns, and are provided in countless numbers over the entire fixing protrusion 6 to form an ice coating 7 including the fixing protrusion 6. As shown in FIG. 4, the ice grains 9 are made of a water pipe 12 having a nozzle 11 at its tip, an orifice 13 at the tip of the nozzle, and a pressure guiding hole 14 for introducing compressed air and liquefied nitrogen into the side wall. A fog-like ice grain is made with a protruding ice grain making device 15. That is, water is supplied to the water conduit 12 and ejected from the nozzle 11, and at the same time compressed air and liquid nitrogen are introduced from the pressure guiding hole 14 and ejected from the orifice 13. Furthermore, as shown in FIG.
8 into the ice-applying machine 19 and ice is deposited on the base 5. The ice formation conditions at this time are -5℃ to -15℃.
℃, and the ice particle injection speed is approximately 15 m/sec. In this state, fine ice particles collide with the fixing protrusions 6 to form a coating 7 of frozen particles including the fixing protrusions 6. Furthermore, as shown in FIG.
After placing the ice particles on the base, the ice particles may be compressed using a press 20 to form the ice film 10.

(Function) Next, the handling procedure and function of the downhill gear according to this invention will be explained. The base 5 with ice grains frozen on the fixing protrusions 6 by the ice grain maker 15 is transported to the entrance of the slide of the large slide device, and the seat 1 is fixed on the base 5 in a placed manner at the said location. Pick up the skiers and push them out onto the slide. The downhill gear supports the downhill gear with the fixing protrusions 6, and slides down by contacting the downhill surface with the ice coating 7 provided on the fixing protrusions 6 while responding to changes in the shape of the downhill surface.

(Effects) According to this invention, the fixing protrusion comes into contact with the sliding surface with a film of countless ice particles, so it can slide down at a sufficient speed even on the sliding surface of a large sliding device with a gentle slope. Is possible. In addition, since fine ice grains can be easily frozen, it has the practical benefit of being easy to handle. Therefore, the period of use is not limited to the summer season, and it is possible to provide a practical large-sized downhill device that can be used throughout the year.
