Description

Four Seasons Sleigh System {FOUR SEASONS SLED SYSTEM}

This design uses cylindrical slides for snow sledding and four seasons to create a line of starting lines to prevent user safety accidents and increase the fun factor. To a four-season sled system for providing a sled to be utilized exclusively for the cylindrical slide.

In a general cylindrical slider or a curved slider, the sled can be lowered with a relatively low resistance by the inclination of the slider.

However, since the slider ends and the sled is settled on the ground, there is a problem that the sled is very strongly resisted and the passenger falls due to the inertia. In order to solve this problem, a ski-like blade is installed on the bottom of the sled so that it can enjoy a relatively low resistance on the ground.

However, the problem is that it is difficult to apply such a blade to a cylindrical slider. Cylindrical sliders are designed to be safe and funny even at high speeds, because when the blades are installed, the slewing speed of the cylindrical slider is lowered due to the friction of the blades and the durability of the inner surface of the slider is weakened.

Therefore, a four-season sled system was needed to enable a sleigh to be safely enjoyed without any resistance even though the cylindrical slider and the ground were evenly crossed.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

FIG. 1 is a perspective view of a four-seasons sled system according to an embodiment of the present invention. The four-seed sled system according to the present invention includes a sled base 100 formed to have a predetermined curvature; A blade 200 provided at both sides of a center of the lower surface of the sled base 100; And a roller 300 provided on both sides of a lower surface of the lower surface of the sled base 100 and provided on both sides of the lower surface of the sled base 100 and outside the blade 200. In a flat surface, And can be supported by the slider 400 through the roller 300.

Specifically, the four-season sled system according to the present invention includes a sled base 100 formed to have a predetermined curvature; A blade 200 provided at both sides of a center of the lower surface of the sled base 100; A roller 300 provided on both sides of the lower surface of the sled base 100 with respect to the center of the lower surface of the sled base 100 and outside the blade 200; And a curved surface slider 400 formed to have a predetermined curvature, which is supported on the flat surface by the blade 200 and can be supported on the curved surface slider 400 by the roller 300.

As shown in FIG. 1, the sled is provided with a sled base 100. The blade 200 is provided on both sides of the center of the lower surface of the sled base 100. The blade 200 can be securely mounted on the ground 600 when the sled is mounted on the ground 600 as shown in FIG. So that the sled base 100 can be slid.

The rollers 300 are provided on both sides of the lower surface of the sled base 100 with respect to the center of the lower surface of the sled base 100 and are provided outside the blades 200. The roller 300 guides the slider 400 on the curved surface so that the sled can slide safely without resistance.

Particularly, by adjusting / designing the height of the blade 200 and the roller 300 to be supported by the blade 200 in the flat surface 600 and supported by the roller 300 in the curved surface slider 400, ) And the plains (600), it is possible to enjoy the sled safely and to minimize the resistance.

Specifically, the point where this sled system is mounted is the ground surface 600. The curved slider 400 has an inclined angle and can enjoy sledging by its own weight. However, the ground 600 needs to be considered in various situations, snow may be piled up, or a playground with lawns may be used.

Accordingly, in the slider 400 having a fixed shape, the slidability through the roller 300 is stable and the resistance is minimized. On the ground 600, however, sliding through the blade 200 is stable and resistance is low, Do not.
