DE202005014036U1 - Stem turn toboggan, on two skis, has a steering joystick to control the spreader arms at the trailing ends of the skis and the tilting arms at the leading end for steering and braking control - Google Patents

Abstract

The stem turn toboggan has a seating surface (1) and two running skis (2,3), together with a steering and braking system. The two skis are linked together by two cross members (4,5), which allow the seating surface to be tilted to either side along the direction of travel. The leading cross member is attached directly to the skis, and the trailing member is linked to the skis through spreader arms so that the two skis are moved on two planes at right angles to each other. The steering joystick (6) acts on the trailing spreader arms and the leading tilting levers through Bowden(RTM) sheathed cables.

Description

The The invention relates to a carriage used as runners skis and thus able to be similar a skier, Curves by means of Stembogen to drive, braking and cross-slope rides to accomplish.

[State of the art]

It are known sleds with moving skids, where the sledder sits very high and thus has an unfavorable focus. The Steerable runners are split or bend. Snowmobiles are known with wide or split drive belts. Hang transverse speeds are not feasible with these sledges on steep slopes. Also it is not possible to glide with the engine off. The engine is mostly very strong, because he is not in serpentines across the hill to the mountain can drive up.

From the description of the invention DE198 57 351 A1 is known a toboggan, in which the seat, in the same direction pivoting about a fixed pivot point in conjunction with the skids.

adversely In this toboggan is that the firm pivot of the seat relative to the driving surface is high and slope, so when driving on slopes and cornering the focus of the toboggan closer to the valley or to the outdoor ski moves, causing there is a risk that the carriage will fall over

Further, the patent AT 217307 and the utility model describe DE 297 22 354 U1 Ski slides in which tilting movements of the skis or skids are effected by a power transmission device.

These Skis are not capable of skids independently and edges to varying degrees, which makes it impossible on the one hand an adaptation to the slope or curve slope takes place and on the other hand, if necessary, a change of direction can be caused.

Farther is known from the patent AT 217307 that over a Control lever a V-position of the skis is possible, causing the carriage is able to make cornering or braking.

One The main disadvantage of this slide is the lowering of the seat after behind, which also carries the risk that the sledder backwards crash can no longer adequately ensure ground clearance is. Motor-driven mountain rides are not possible for this reason.

OBJECT OF THE INVENTION

task The invention is to provide a Stembogenogenschlitten, the the advantages of a Stembogenskiläufers with the advantages of a Rodlers combined, being a favorable Center of gravity and center of gravity distribution for slope and / or cornering to be realized. Furthermore, should be used as runners original scarf and an energy-saving design as a snowmobile possible be.

The Task is with the inventive features of the first protection claim solved. Advantageous developments and refinements are the subject matter the dependent claims.

Of the Stembogenogenschlitten consists of a seat and transport surface, two under the seat and transport surface Skids arranged as runners and a steering and braking device. The two skis are over two convex curved trusses connected to each other on which the seating and transport area in Direction of travel is pivotally arranged on both sides.

The a, in the direction of travel front cross member is directly with the skis and the other, in the direction of travel rear cross member is via spreader arms connected to the skis. In the attachment points on the trusses The skis are arranged so articulated that they are in two axes are movable perpendicular to each other. By turning the skis around an axis along the Ski these are tilted and by turning around a perpendicular to this Axis can the skis from the parallelism out V-shaped adjusted become. Through these possibilities of movement, controlled by a joystick, The functions steering and braking are realized.

To the Tilting the skis, the joystick is moved laterally, taking at the same time the entire seat and transport surface sliding on the trusses is pivoted and the canting in the same direction in the Attachment points of the skis arranged Kantungshebeln takes place.

For a V-shaped start the skis become the joystick pulled back.

About two on the joystick arranged, separately operable Handles can the skis are tilted differently, which together with the V-shaped adjustment, Curves (Stembogen) can be driven.

Conveniently, the trusses are bent so that the fictitious pivot of the swivel seat and transport surface is located below the running surface.

Further It is advantageous that the joystick and the separately operable Handles by means of a power transmission device are connected to the expansion levers and the Kantungshebeln.

In a further advantageous embodiment can be the Stiesbogenogenschlitten by a motor with a propulsion part move.

By a modular construction, divided into three main assemblies ski, Seat and transport area and Motor with the propulsion part, the carriage is easy to install, variable in design and easy to transport. Original skis equipped with appropriate adapters.

Summarized be built with the invention Stembogen slides the movements V-shaped prying out, Ankanten the skis or runners and slope inclination with the help of a joystick solved. The optional motor drive is through a in the middle of the carriage einzuhängendes Motor part together with a long drive belt as propulsion means solved.

By Ankanten the skis are energy-saving slope crossings possible.

at Downhill slopes, the engine is issued and the propulsion section (order a ground clearance to create) raised.

About obstacles (fallen trees, Streams etc.) the carriage can be lifted due to its light weight become.

In 1 the Stembogenogenschlitten is shown in a schematic side view, occupied by two people. It consists of a seating and transport area 1 Skiing on a pair 2 . 3 , which form the skids of the carriage, by means of a front 4 and a rear traverse 5 is mounted.

The steering and steering is done by means of a joystick 6 ,

On the basis of the drawings 2 to 5 is the structure and operation of the carriage after 1 shown in several views.

The steering is similar to a skier who drives Stembogen. While sliding the skis 2 . 3 becomes the joystick 6 pulled back. This spreads with the help of spreader arms 7 the skis 2 . 3 ( 2 ). In the front position of the joystick 6 run the skis 2 . 3 , as in 3 to see in parallel.

With lateral movement of the joystick 6 from the middle position ( 4 ) this will be in 5 together with the seating and transport area 1 moved, with the skis 2 . 3 ankanten in the same direction and so slope crossings are possible, in which the seat and transport surface 1 always remains in the horizontal and an imaginary axis of gravity 11 through a fictitious fulcrum 12 the seating and transport area 1 runs. Due to the structural design of the Stembogenbogenschlittens lies the fictitious fulcrum 12 below a driving surface 10 ,

Anchoring the skis 2 . 3 via canting lever 8th at the attachment points of the skis 2 . 3 at the crossbars 4 . 5 ,

The execution of cornering shows 6 , These are located on the joystick 6 two separately arranged swivel lever handles 13 in the form of angle levers, via a linkage with the Kantungshebeln 8th to the ski 2 . 3 connected are.

Will the left swivel lever handle 13 pressed down, the right ski cant 2 and a left turn begins. In a right turn (in 6 shown), the maneuver is carried out analogously. The right swivel lever handle 13 is pressed down and the left ski 3 cant. And so on, the joystick 6 pulled back, the more spread the skis 2 . 3 and the smaller the radius of the curve.

When braking both skis 2 . 3 Ankantet by the joystick 6 is pulled in its center position to the rear and at the same time both swivel lever handles 13 pressed down. The more the skis 2 . 3 be spread, the greater the braking effect.

By combining the Stiesbogenschlitten with a motor 9 ( 7 to 10 Steep mountains can be driven uphill in serpentines with a relatively small engine power.

8th shows an enlarged view of the motor drive, consisting of the engine 9 and a propulsion part 14 , The propulsion part 14 consists in this embodiment of a narrow, over pulleys 16 guided belt 15 ,

Is the belt 15 too wide, cross-slope travel is difficult to do.

In conjunction with the Stemgen bow control according to the invention 2 to 6 It is possible to turn when cornering, shown in 9 how to put a motorcyclist in the corners. This is the axis of gravity 11 by pivoting the seat and transport surface 1 on the curved trusses 4 . 5 moved to a favorable position.
