Skis, or sleds for off-road car

Skis are tools that people put on their feet to move through the snow more easily and faster.

The sleds have the same function, but one can sit on them while someone else is pulling or pushing them.

Off-road cars are used for rough terrain and can be used on hard and shallow snow. However, in deep snow, when the bottom of the car drops to the snow level, the off-road vehicle can no longer move. If the car were to be mounted on a sled, or a large ski, then it could move on its wheels that would be shallow in the snow.

Off-road skis like this would not be difficult to make.

The basic part of this tool is a large ski (3) lying on the snow and skidding on it. On the ski (3) there is a car carrier (4) which can be positioned above the ski (3) and can be lifted several tens of centimeters above the ski (3). The skis (3) and the car carrier (4) are connected by the risers of the carrier (5), which are slanted relative to the ski (3) and the car carrier (5), and perpendicular to them when the car carrier (4) is raised above the ski ( 3). Lifting the car carrier is done by the Carrier Lift Bolt (7), which connects the skis (3) and the car carrier (4) from the front. Lifting the car carrier (4) is done by rotating the carriage mounting bolt (7) so that the distance between the front of the ski (3) and the front of the car carrier (4) is reduced. In this way, the lifting brackets (5) are raised from the oblique position to the vertical position, thus raising the car carrier (4) upwards. This also raises the car (1) upwards and places it above the snow level. This reduces the friction resistance between the snow and the vehicle and the wheels (2) have sufficient power to start the car (1). In order to prevent the skis (3) from moving relative to the car (1), the car carrier (4) must be firmly connected to the car (1). This is accomplished by placing the carrier grips (6) around the car sills and tightening them in this position. Since car thresholds have a different shape for each type of car, the carrier grips (6) must be adapted to the car thresholds, or other parts of the car located at the bottom of the car. Therefore, these carrier grips (6) should be made separately for each type of car.

Using such off-road skis, the vehicle could travel in deep snow without the risk of falling into deep snow. The skis is transported in the collapsed position on the roof rack, and when the vehicle arrives in deep snow, the skis are removed from the roof rack, placed under the car (1). Then, by rotating the lifting bolt (7), the car carrier (4) is raised together with the car (1). The car carrier (4) is then firmly connected to the car sills by tightening the carrier grips (6).

And in this way, passengers in the off-road car can continue to move safely across the snow.
