Definitions

  • This invention relates to a self-propelled unit able to propel a person wearing snow skis along a rising snow path, comprising a frame, rolling means for the movement of the self-propelled unit along the snow, an engine for driving the rolling means, a transmission which connects the engine to the rolling means, and engine control means.
  • Self-propelled units of the aforesaid type for use by a skier in overcoming a rising path are already available commercially.
  • the types proposed up to the present time are however in the form of actual vehicles of considerable weight and overall size, and of high cost.
  • the main characteristic of the self-propelled unit according to the invention is that it is of such dimensions and weight as to be portable, and that said self-propelled unit is also provided with means for its releasable connection to the skis and sticks of the skier, said connection means being configured in such a manner that a large part of the skier's weight acts on the self-propelled unit.
  • the self-propelled unit according to the invention can be advantageously used by a skier in order to overcome an upward snow path, after which it can be carried on the shoulders and conveyed downhill during the next descent on the skis.
  • FIG. 1 shows a skier 1 wearing snow skis 2 during upward movement. This movement is obtained by the self-propelled unit according to the present invention, in the manner described in detail hereinafter.
  • the self-propelled unit is indicated overall by the reference numeral 3. This unit is controlled by the skier by means of a handle 4 connected to the ski sticks 37 and by means of a bundle of flexible cables 5 connected to the unit 3.
  • the skier separates the self-propelled unit 3 from the skis 2 and sticks .37 , and straps it as shown at 6 ( Figure 2) by means of straps 38 with which the unit is provided, so that he can carry it on his shoulders during his subsequent descent on the skis.
  • said unit comprises a frame 7 (see Figure 5) on which a pair of front wheels 8 and a pair of rear wheels 9 are rotatably mounted.
  • the wheels 8, 9 comprise peripheral recesses 10 in which the ends of transverse bars 11 (see Figure 4) forming part of a crawler track 12 engage.
  • the self-propelled unit comprises two lateral protection walls 13 screwed to the frame 7 (see Figures 3, 4), and from which there project two lateral supports 31 which are fixed to the frame (see Figures 5, 6).
  • the free ends of the brackets 14 each comprise an articulated connection unit 15 (see Figure 3) designed for releasable fixing, for example by means of a bayonet or instant insertion connection, to a corresponding connection plate 16 situated on the rear end of the ski 2.
  • Each articulated connection unit 15 enables a support 17 to rotate relative to the bracket 14 about a longitudinal horizontal axis 18, and enables a plate 19 (to be fixed to the plate 16) to rotate relative to the support 17 about a vertical axis.
  • the arrow A indicates the direction of movement of the self-propelled unit according to the invention, which as stated heretofore is in the form of a crawler-tracked unit, in the illustrated embodiment.
  • An internal combustion engine of small piston displacement is mounted on the frame 7 of the self-propelled unit in a forward position between the two front wheels 8.
  • the shaft of the engine 20 is connected to the rear wheels 9, which act as drive wheels, by a transmission including an automatic clutch of known type used for example in mopeds (indicated by 21 in Figure 6).
  • an automatic clutch of known type used for example in mopeds (indicated by 21 in Figure 6).
  • the clutch 21 controls an automatic variator 23, which is also of known type used for example in mopeds.
  • a drum brake 24 (see Figure 7) is mounted on the shaft of the automatic variator 23. This shaft is also connected by a chain transmission 25 to the shaft of the rear wheels 9..
  • the reference numeral 26 indicates overall a device for adjusting the crawler track tension.
  • the reference numerals 28 and 29 indicate respectively the fuel tank and exhaust silencer of the internal combustion engine.
  • the reference numeral 30 indicates a pulley about which a cable is wound for starting the engine (see also Figure 4).
  • the handle 4 includes a member for adjusting the engine rotational speed. As the rotational speed increases, the automatic clutch 21 gradually transmits the torque from the engine to the wheels.
  • the automatic speed variator 23 sets the optimum transmission ratio at all times in relation to the load conditions and the slope of the path.
  • a self-propelled unit of the type heretofore described can enable the skier to overcome ascents up to a maximum slope of 40% at a maximum speed of about 20 km per hour.
  • the brake 24 is operated by means of the handle 4.
  • direction changes are made by the usual method in skiing, namely shifting the weight of the skier from one ski to the other.
  • the articulated connection units 15 enable the skis to be tilted on to their front edge, while the self-contained unit remains in contact with the ground.
  • the handle 4 also includes a control for stopping the engine.
  • a control for stopping the engine within the principle of the invention, the constructional details and shape embodiments can be widely modified relative to that described and illustrated by way of example, without leaving the scope of the present invention.
  • an electric motor could be used instead of an internal combustion engine.
  • a self-contained unit comprising for example two crawler-tracked means designed for connection laterally to the skis and arranged to be controlled separately in order to obtain a more precise control of the direction of movement.
  • movement along the snow could be obtained by a series of wheels or by one or more rotating propellers which grip the snow surface.
  • a crawler track could also be used which does not pass around the entire structure of the machine, but which instead is disposed below said structure.
  • the structure could be protected by cover walls.
  • the wheels on which the track engages could be rubber wheels instead of toothed wheels.
  • the self-propelled unit according to the invention can also be applied in general to vehicles fitted with snow skis or skids in order to propel them.
  • the self-propelled unit can be arranged in another manner, for example not directly connected to the skis, so allowing the skier greater freedom of movement.
  • the skier can be connected to the self-propelled unit only by way of the skis, so remaining upright and holding not only the sticks but also a handle for controlling the unit, which is connected to it by flexible conductors.
