It consists of an internal combustion engine 20 for driving the track 12, a transmission 21.25 for connecting the internal combustion engine 20 to the crawler track 12 as a rolling device, and a handle 4 as a control device for the internal combustion engine 20. The self-propelled unit 3 has portable dimensions and weight. The self-propelled unit includes the skier's snow skis 2 and skis of the frame.
Device 14 for making a releasable connection to the stock 37
and 34 are also provided. Said connection device 14.34 is constructed in such a way that the majority of the skier's weight acts on the self-propelled unit.

The present invention relates to a frame, a crawler device which is a relocation device that moves a self-propelled unit along the snow surface, an engine that drives the crawler device which is the relocation device, and a connection of the engine to the crawler device which is the relocation device. The present invention relates to a self-propelled unit that is capable of propelling a person wearing snow skis along an uphill snowy road, which includes a transmission and an engine control device.

1. Self-propelled units of the type described above for use by skiers to overcome downhill slopes are already commercially available. However, the models that have been proposed to date have considerable weight and overall dimensions, and are expensive in the form of actual vehicles.

The main features of the self-propelled unit according to the invention are that the dimensions and weight of the unit are such that it is portable, and that said self-propelled unit is provided with a releasable connection to the skier's lh skis and ski poles. The device is also equipped with a failure connection device Fi-h''- configured in such a way that most of the skier's weight acts on the self-propelled unit.

Such 'l'! In accordance with the present invention, the J'rII self-propelled unit is designed to overcome snow-covered slopes.
Second, it can be advantageously used by skiers, who can carry it on their shoulders after going up a slope and then carry it down the ski slope.

Other features and advantages of the invention as a non-limiting example! It will become clear from the description that follows with reference to the accompanying drawings.

FIG. 1 shows skier-1 wearing a snow-]-] sugee during a climbing exercise. This pitching motion is carried out by a self-propelled unit according to the present invention in a manner to be described in detail hereinafter.
). In FIG. 1, the self-propelled unit is generally indicated by 3. The unit I is connected to the handle 4, which connects to the ski pole 37, and to the self-propelled unit 3. is controlled by a gearer through a bundle of flexible cables 5.

At the end of the pitch, the skier propelled the self-propelled unit 3 into the snow.
The unit is then removed from the Niski 2 and ski pole 37 and placed on the belt 38 attached to the self-propelled unit (as shown at 6 in FIG. 2). Therefore, skiers can still carry the unit on their shoulders when descending from snow skis).

Referring to FIGS. 3 to 7 showing preferred embodiments of the self-propelled unit according to the present invention, the unit has a pair of front wheels 8 and a pair of rear wheels 9 rotatably installed. This includes frame 7 (see FIG. 5). The front wheels 8 and the rear wheels 9 have circumferential notches 1 into which the ends of transverse bars 11 (see FIG. 4) forming part of the crawler track 12 engage.
0 is the default.

The self-propelled unit comprises two lateral supports 13 screwed to the frame 7 (see FIGS. 3 and 4), from which lateral protection walls there are two lateral supports 13 fixed to the frame. The support body 31 protrudes (see FIGS. 5 and 6)
. On the lateral support 31 there are two brackets 14 which project forward from the self-propelled unit and are rotatable about a lateral axis 32 (see FIGS. 3 and 4) and which support the ski poles on the lateral axis. A quick and releasable fastening to both lower parts (see FIG. 3) of the ski pole 37 is provided, for example by means of a bayonet fitting, so that it can be pivoted about an axis 33 at right angles to 32. The arm of the fork 34 is connected to a plate 39 (FIG. 3) which is designed for the purpose of installation.

Each 111 end of the bracket 14 is designed for releasable attachment, for example by means of a bayonet fitting or a quick-insertion fitting, to a corresponding connecting plate 16 mounted on the rear end of the snow ski 2. articulated connection unit 15 (
(see Figure 3). Each articulated connection unit 15 connects a support 17 to a bracket 14 about a longitudinal horizontal axis 18.
The plate 19 (fixed to the connecting plate 16) can be rotated relative to the support 17 about the ili' axis. .

Because of this arrangement IFt, when the articulated connection unit 15 is connected to the snow ski 2 and the plate 39 is connected to the ski pole 37, most of the skier's weight is transferred to the connection bracket 14. Due to the solid connection constituted by the support fork 34, the self-propelled unit 3 acts on the self-propelled unit 3, and at the same time gives the snow ski 2 and the ski pole 37 the necessary degree of freedom to control the direction of movement and the execution. The required diagonal movement can be achieved.

In the drawing, arrow A indicates the direction of movement of a self-propelled unit according to the invention, which in the illustrated embodiment is in the form of a crawler-suspension unit, as described above.

Mounted on the frame 7 of the self-propelled unit in a forward position between the two front wheels 8 is a small piston-moving internal combustion engine, indicated at 20 in FIG.

The shaft of the internal combustion engine 20 is connected to the rear wheel 9, which acts as a drive wheel, by a transmission including an automatic clutch of the known type (designated 21 in FIG. 6) used, for example, in motorized bicycles. By means of the belt 22, the automatic clutch 21 controls an automatic variable 23, also of the known type used, for example, in motorized bicycles.

A drum brake 24 (see FIG. 7) is installed on the shaft of the automatic variable device 23. This shaft is also connected to the rear M9 shaft by chain transmission 25.

In the drawing, reference numeral 11 (1 number 2G generally controls the crawler track tension) device 17/1° is shown. In FIG.
An exhaust silencer is shown.

Finally, in FIG. 6, reference numeral 30 designates the pulley around which the cable is wound for the purpose of starting the engine (see also FIG. 4).

When the skier wishes to climb, the skier connects the connecting end of the bracket 14 to the snow ski 2, and connects the plate 39, the central part of the fork 34 serving as a support, to the ski pole 37. A seat 35 and a control handle 36 are installed on the ski pole by screws, after which the skier starts the internal combustion engine 20 by means of the pulley 30. The handle 4 includes a member for adjusting the rotational speed of the ennon. As the rotational speed increases, the automatic clutch 21 gradually transmits torque from the engine to the wheels. The automatic speed variable 23 sets the optimum transmission ratio at all times in relation to load conditions and path slope conditions.

According to the self-propelled unit of the type described in explanations 1 to 1, the skier can move up to 40% at a maximum speed of about 201 cm per hour.
You can overcome the uphill slope up to the slope of .

To reduce the speed, actuate the drum brake 24 with torque 4.

In the example so far described, the change of direction is accomplished in the usual way in skiing, ie by shifting the weight from one ski to the other. Along a path of slight slope, the articulated connection unit 15 allows the ski to tilt onto its leading edge, while the self-contained unit remains in contact with the ground.

The handle 4 also includes a control device for stopping the ennon.

Within the principles of the invention, the structural details and aspects of the configuration 1-.1-. It can be modified extensively.

For example, an electric motor could be used instead of an internal combustion engine.

For example, two crawlers are installed so as to be connected to the cedar in the hffi direction (1 x 7 inch 1. + 1 - layer in the interlocking direction) and are individually controlled for accurate control. - It is also possible to provide a self-contained unit that includes the Nogawa device a.

Furthermore, instead of using a crawler-1 platform, movement along the snow may be accomplished by a series of wheels or one or more rotating wheels gripping the snow surface.

It is also possible to use crawler tracks that do not pass around the entire machine structure, but instead are arranged and serve below said structure.

In this case, the skid can be protected by a cover wall. The wheels on which the track engages the river can be rubber wheels instead of toothed wheels.

Finally, the self-propelled unit according to the invention is also generally applicable to vehicles equipped with snow-one-skis or sleds for propelling the vehicle.

In other embodiments (not shown), the self-propelled unit can be arranged in other ways, for example without being directly connected to the skis, giving the skier considerable freedom of movement. In an alternative and most simplified embodiment,
The skier can be connected to the self-propelled unit only via the skis, thus remaining upright and holding not only the ski pole, but also the handlebars for controlling the unit, which is connected to the handlebars by flexible conductors. do.
