Description

Sledding

The field of technology.

The utility model relates to snow scooters and devices intended for active slalom downhill from the mountains, as well as for extreme skiing from the mountain slopes of ski resorts or any other snow slopes that have sufficient space for maneuvers.

The prior art.

Various models of snow scooters produced by Russian and foreign manufacturers are known from the current level of technology (see, for example: http://sportandrest.ru/catalog/sani/snegokat,

http://kids.wikimart.ru/transport/snowscooter/model).

Such models of snow scooters, as a rule, contain a supporting frame with two runners fixed on it and an oblong-shaped seat, a front steering rack with a spring shock absorber, rotary ski and steering wheel, as well as a foot brake of a scraper type. Common to all snow scooters is an insufficient level of controllability and stability.

Known (prototype) a snow scooter according to the patent of the Russian Federation for utility model Ν ° 106596, including a supporting frame with two skis and an elongated seat fixed to it, a front steering rack with a spring shock absorber, a rotary ski and a steering wheel, a scraper type foot brake and a backrest, made in the form of a tubular frame of an arcuate shape, pivotally attached to the supporting frame under the seat with the possibility of rotation in the vertical plane and fixation in predetermined positions, while the configuration of the back provides a folded polo In this case, the back frame is fitted to the side of the seat.

In this snow scooter, the overall center of gravity is high (due to the almost vertical position of the rider’s back and high seating position), which increases the likelihood of tipping over when descending from the mountain and when cornering. And managing only the front ski does not provide proper accuracy in the turns due to the peculiarities of the (slippery) snow surface, on which the ski with its own

SUBSTITUTE SHEET (RULE 26) smooth surface continues rectilinear movement, despite its rotation. All these factors, in general, deprive the rider of the opportunity to fully control the snowmobile, which cannot but affect security, due to the inability to timely and efficiently go around the obstacle.

The technical result.

Improving the convenience and safety of operation, improving consumer qualities.

Disclosure of a utility model. The technical result is achieved due to the fact that in a snowmobile sleigh that includes a supporting frame with two rear skis fixed to it and a seat with a back, a front steering rack with a steering wheel and a foot brake pedal, a foot brake comb, two rotary skis are installed on the steering rack located relative to the frame outside its lateral sides, the foot brake-comb is located between the two rear skis and connected to the foot brake pedal, while on the sides of the frame are mounted handlebars-levers equipped on them to onts with steering brake blades, as well as levers lowering the steering brake blade with the fixed position of the handlebars, levers. A snowmobile sled, including a supporting frame with two rear skis and a seat mounted on it, a front steering rack with a foot rudder, a comb foot brake and a backrest, characterized in that the steering column has two rotary skis located relative to the frame outside its side of the sides, the foot brake-comb is located between the two rear skis and is connected to the foot brake pedal, while on the sides of the frame there are manual handlebars-levers equipped with steering brake blades, as well as levers lowering steering brake blade with the fixed position of the handlebars, levers.

The presence of handlebars, levers, coupled with a front steering rack and two rotary skis, as well as a low center of gravity provided by the seat,

SUBSTITUTE SHEET (RULE 26) which the rider is in a reclining position, allows you to ride fast, without fear of overturning and effectively control the sleigh-snowmobile - make sharp turns (perform slalom). Manual handlebars-levers allow you to control a snowmobile sleigh, both by means of the steering brake blade control levers (in the fixed position of the handlebars-levers), and by moving the center of gravity from left to right and pressure on the handlebars-levers by the elbows (in the uncommitted position of the handlebars levers, while the manual rudders-levers are returned to their original position by means of springs), these control variations are convenient when riding on different slopes with snow having different densities or depths and depths th bias. By pressing elbows on the handlebars-levers (or by clamping the control levers of the steering brake vanes), the left or right side of the rear of the sleigh is alternately braked by special steering brake vanes at the ends of the levers, which abut in the snow, the so-called drift (lateral sliding) ) This control method is optimal when descending on snowy slopes and is great for extreme skiing, slope racing, etc.

The variability and control style of the snowmobile sleigh can be changed thanks to the steering wheel locks: for active sports driving, both present types of steering wheel are used - the front foot wheel (consisting of a steering rack and two rotary skis), and handlebar-levers (without being fixed).

For more measured riding on relatively gentle slopes, you can use only the front foot wheel, fixing the manual rudders-levers.

For beginners, it will be convenient to operate the sled only with handlebars, levers. The snowmobile sleigh can be controlled with the help of the steering brake paddle levers (in the fixed position of the handlebars-levers) on not very steep slopes with a dense and smooth snow cover, for a quicker response of the snowmobile to the "command" turn.

The foot brake-comb provides confident deceleration and stopping of the snowmobile sleigh, without distraction from control.

SUBSTITUTE SHEET (RULE 26) Adjusting the seat and lateral support for the departure, and handlebars, levers along the length allow you to comfortably sit on a snowmobile sleigh and just as comfortable to control a person of any complexion. Also, the ease of management allows anyone, regardless of age and physical condition, to master these sleds in the first minutes of skiing, which in turn cannot but affect their popularity.
