Definitions

• the essence of the invention is a Schnälgecorpirt on flat snow runners, particularly suitable for driving on the snow slopes for recreational and sports purposes (leisure purposes), even for people of average fitness, whose possibilities of skiing are limited.
• Skibob known from the Polish patent specification No. 156022 has a Lenkele enl from the front, which is equipped with a flat skid.
• the rear part of the vehicle also a flat skid
• the front part is connected to the front part by means of a bush rotating on the mandrel (over-bearing). Because of the double support, the trip on it requires a large production and also putting on the additional skis, which makes it difficult for the user to move between the runs.
• German Patent No. 2607748 which is intended for descending in special gutters, is supplied with steering systems and tilting mechanisms that only allow small turns. As a result, this solution cannot find the application for the descent from the snow slopes.
• the proposed snow vehicle has the steering front part and the rear part with a seat.
• the rear of the vehicle is rotatably connected to the front.
• the whole is designed as a parallel crank with a mandrel fastened in its axis of symmetry with a holder, whereby this rotary connection is a bush fastened to the front end of the frame, which is placed on the mandrel and supported by a spring element.
• the mandrel is rotatably and slidably attached to the horizontal elements of the parallel crank.
• the parallel crank is designed as an equilateral trapezoid with a longer base, and all of its joints have a degree of freedom and lie in a plane perpendicular to their axis of rotation.
• the mandrels, on which steering runners are rotatably mounted, are fastened on the lower, outstanding sides of the parallel crank, approximately in half their length.
• the rear snow blade, in half its length, is rotatably connected to the rear of the frame and to the mandrel.
• the rear end of the arm is slidably mounted on this mandrel, supported with suspension element and supplied with the attached seat.
• the front end of the arm is pivotally attached to the front end of the frame.
• the variation of the vehicle according to the invention is characterized in that the rear part with the seat is rotatably and tiltably connected to the front part.
• the front part is a parallel crank with the designed in its axis fixed mandrel, which has a holder, the rotatable and tiltable connection is the articulated to the front frame bush, placed on the mandrel and supported with the r ⁇ ed mecanicselement.
• the vehicle according to the invention is characterized by the simple construction, which enables its problem-free execution, high performance and reliability.
• the rotatable attachment allows all snow runners to adapt to the shape of the terrain.
• Vehicle supported on three runners ensures the stable position of the descendant and his safe departure.
• the variation of the slope enables the forward inclination change to be carried out in the symmetrical plane of the rear part. This enables the twists.
• the vehicle, according to the invention can be used with the skiers on the snow slopes and use the ski lifts (drag lifts).
• the vehicle consists of the front steering part, which is designed as a parallel crank X.
• This element has a mandrel j with handle 2 in its axis of symmetry. The whole is rotatably connected to the rear part provided with seat 4.
• the connection consists of a front frame _5 fastened to the bushing 6, which is placed on the mandrel 3 and is supported by the conveyor element 7.
• the parallel kuibel is designed as a trapezoid with equal arms with a longer base, and its four joints 8_ each have a degree of freedom and lie in a plane perpendicular to their axis of rotation.
• the mandrel 3rd is to the horizontal elements £ and 10 of the parallel crank.
• the lower end of the dome 24 is connected to the rear end of the frame _5_ and the rear runners ⁇ 7 by means of the joint 2 ⁇ ».
• the bushing mounted on the mandrel _3> is connected to the frame 5_ by means of a joint.
• the descendant sits on the seat. the rear portion and is supported on the runners 19 on snow i 0 Laid feet which serve as a l ⁇ enkelement.
• the runners J_9_ and _2 ⁇ can be turned around the longitudinal axis, which allows tilting during inclined descent and during turns.
