Description

The technical solution relates to vehicles on a snowy and snow-ice surface, namely, to driven inflatable sledges designed to descend from snowy slopes and mountains.

Managed inflatable sledges are known (utility model of the Russian Federation No. 155369, published on 10.10.2015), consisting of an inflatable element placed in a cover, while the lower part of the sled is equipped with skids in the form of a ski. The rotation of the ski is carried out using the steering wheel or flexible rods.

These sleds are not safe enough when using them, especially at high speed and steep slopes. Parts of the control mechanism, such as the axle and steering wheel, in case of accidental collision of the sled with foreign objects at high speed can cause injury to the sleigh.

The invention is known: “An inflatable raft for snow-rolling at an adjustable speed with spikes, international application (US 20170050664 (USA), publication date: 02/23/2017, priority date 1514686.3 08/18/2015 GB (United Kingdom). An inflatable raft for snow-rolling has unlimited number of studs with which you can adjust its speed when descending from a snowy mountain.

The disadvantage of this invention is that at high speed the studs (spikes) will cut deep into the snowy track and spoil it, and this leads to undesirable consequences.

Known children's sledges (utility model of the Russian Federation No. 128171, published May 20, 2013) are plastic sledges equipped with bottom longitudinal ribs, the side ribs are shortened, and the front ends of the ribs and the rear ends of the side ribs have a bend outward and go to the front and side walls.

The disadvantage of these sleds is that when a bump occurs, there is a torque, the sled begins to rotate, the trajectory is unpredictable, and this can lead to injury not only to those who are in the sled, but also to those who are nearby.

The objective of this technical solution is to create an inflatable sled that allows you to control them (change the direction of movement) at different speeds with minimal installation of rigid structural elements.

This object is achieved in that the inflatable sleigh containing a frame in the form of an inflatable element, a shell and sleigh movement control elements, as a control element for the movement of the inflatable sleigh are guides that are located on the lower part of the shell of the inflatable sleigh parallel to the central axis of symmetry and along one side guide located on each side and made in an arc passing to the side surfaces of the shell of an inflatable sled. All guides have ridges located parallel to the axis of symmetry of the guide.

The technical solution is illustrated by the following drawings:

FIG. 1 general view of the sleigh,

FIG. 2 bottom view

FIG. 3 side view

FIG. 4 and FIG. 5 sled movement on the highway

In FIG. 1 shows a general view of the sleigh of paragraph 1. in an inflated condition. In FIG. 2 shows the lower part of the sleigh in contact with the snow floor, where 2 is the central guide, which is located along the central axis. Figure A shows a part of the central guide with ridges 4 located parallel to the central guide 2 itself.

In FIG. 3 shows a side guide 3 having an arc shape. Figure B shows a part of the lateral guide with ridges 4 located parallel to the axis of symmetry of the lateral guide 3.

When descending from a snowy slope or mountain on a snowy surface, the sled is able to change the direction of movement of the sled.

The principle of operation of a technical solution can be described as follows. When descending along a snow trap, the central guide 2 provides rectilinear movement if the center of gravity of the sleigh coincides with the vertical plane passing through the central axis of the sleigh.

When the sleigh is tilted to the left, that is, when the center of gravity of the sleigh is shifted to the left, the sleigh tilts relative to the horizontal plane passing through the central axis to the left. The left side guide 3 is connected, the sleigh continues to move on two guides of the central 2 and the left side 3. As a result, the sleigh changes the direction of movement to the left.

With a larger shift of the center of gravity of the sleigh to the left, the sleigh moves to the side guide 3, and the central guide 2 is turned off from work, due to this the angle of rotation of the sleigh to the left increases.

When the sleigh is tilted to the right, that is, when the center of gravity of the sleigh is shifted to the right, the sleigh tilts relative to the horizontal plane passing through the central axis to the right. The right side rail 3 is connected, the sled continues to move on two guides of the central 2 and the right side 3. As a result, the sled changes the direction of movement to the right. With a greater shift of the center of gravity of the sleigh to the right, the sleigh moves to the side guide 3, and the central guide 2 is turned off, due to this the angle of rotation of the sleigh to the right increases.

Thus, transferring the center of gravity of his body, the sleigh can easily control the direction of movement of the sleigh at various speeds. The test speed reached 70 km / h, FIG. 4 and FIG. 5.

The experimental batch of guided inflatable sleds “SNOWLET” (trademark Certificate No. 619136, copyright holder of LLC “INPLASTECH”) passed the tests and the task was achieved.
