Definitions

  • the present invention relates to installations of which there are different variants and which provide, as an attraction, the descent of small vehicles on a substantially concave track placed on more or less steep slopes, so that the user, seated on the vehicle , descend these slopes more or less quickly depending on whether it operates or not, either a brake acting by friction on the list or brakes acting on wheels.
  • the track is formed by the juxtaposition of concrete elements more or less sunk into the ground, which constitutes a permanent and heavy construction.
  • rail elements are placed on the ground and can be dismantled.
  • a raceway is provided at the base of the ski lifts and the downhill track is installed so that its starting point is close to the upper end point of the ski lift, in particular following it to provide a continuous circuit.
  • ski lifts are designed for the direct traction of a user who slides on snow by the intermediary of skis and whose body is flexible and articulated enough to play the role of a kind of shock absorber when the user grasps the handle which is part of the ski lift.
  • the user's body absorbs jolts and there is no fear of derailment effects since the user is directly placed on the slippery floor.
  • the present invention makes it possible to remedy this and to provide for the ascent of small vehicles without danger of derailments even at the time when the mechanical lift suddenly exerts its effect.
  • the subject of the invention is a device for the ascent of small vehicles which must subsequently descend a slope by gravity on a track, of the type comprising lift members which must rest on a ascent path for vehicles and mechanical means. of traction of the latter, characterized in that the ascent path includes spans parallel to the contact plane of the lift members and diverging and inclined lateral edges, of level higher than that of the spans.
  • the invention concerns small vehicles of known type, the whole configuration of which recalls a simple sledge and having a body A supported by wheels B and C having a camber, that is to say - say mounted on non-parallel ⁇ and ⁇ rolling axes but converging towards each other in the axis of the vehicle.
  • the latter also includes a braking system here comprising a pivoting lever D associated with a friction pad E capable of being brought into contact with a track (not shown) on which the vehicle is intended to descend by gravity. Braking can also be exerted on the wheels.
  • a raceway which includes spans 1 and 2 parallel to the axes a and f3 of the wheels B and C and divergent and inclined lateral edges 3 and 4 of higher level. to that of staves 1 and 2.
  • the wheels B and C of the vehicles are perfectly applied on the ranges 1 and 2 and there is no need to fear any derailment because if lateral forces are applied to the vehicle the inclined edges 3 and 4 have the effect of straightening the vehicle to bring it back exactly in the axis of the raceway so that the wheels find the bearings 1 and 2.
  • the spans 1 and 2 are joined together by a solid median element 5 consisting of planes 5a 5b forming between them an obtuse angle and, since these planes are exactly located in the extension of the spans 1 and 2, they are parallel to the axes ⁇ and ⁇ of wheels B and C.
  • a continuous section is thus formed which makes it possible to construct the raceway according to the invention by juxtaposition of elements which are identical to each other.
  • the middle element 5 has a substantially concave shape so that rainwater tends to run from the top of the side edges 3 and 4 to the center line by which the planes 5a and 5b meet.
  • the element which has just been described may, for example, be made of folded sheet metal and to give it rigidity, provision may be made to join the flanges 11 and 12 by cross members 13.
  • a continuous section is produced which has two spans 100 and 200 joined together by a median element 500, the section of which no longer forms a dihedral as in the previous case but a curve whose lowest central line is virtual because we have provided in the center of the element a 510 channel for the collection of rainwater. Holes (not visible in the drawing) in channel 510 allow the evacuation of rainwater.
  • the lateral edges 300 and 400 are connected to inclined sides 900 and 1000 which end horizontally with flanges 1100 and 1200
  • span 100 is separated from the edge 300 by an intermediate portion 110 more abrupt than the span 100.
  • the range 200 is separated from the edge 400 by a part 210 more abrupt than the range 200.
  • the element itself and the rebate 1500 are connected by a projection 1510 of height substantially equal to the thickness of the element so that another identical element can be aligned with the first by placing it on the rebate 1500 without forming any sensitive continuity solution notably at ranges 100 and 200.
  • FIG. 4 shows a segment of such a raceway produced by the juxtaposition of three elements of the type shown in FIG. 1.
  • the pole 15 is secured to a carriage driven by a continuous cable passing over pulleys attached to pylons j the assembly is often called "ski lift”, or "ski lift”.
  • a reel 16 with elastic return is provided for a cable 17, the free end 18 of which is provided with means (not shown) enabling it to be hooked to the vehicle A and, preferably, at the top of the lever D.
  • the traction exerted by the pole 15 is damped because if this sudden force is greater than the elastic return force of the reel 16, the cable 17 is deployed to absorb the shock without transmitting it to the vehicle A, which does not begin its movement only gradually, by catching up the cable 17 by means of the reel 16.
  • the tensile force of the pole 15 tends to relieve the weight of the vehicle A and this effect can go, with the devices of the known technique, to cause the derailment of the carriages, but here this is made impossible thanks to the presence of side edges 3 and 4.
  • the damping effect due to the reel 16 allows a higher speed of the mechanical lift means while ensuring a gradual start.
  • the reel 16 recalls the released cable 17 so that it does not risk dragging on the ground during the journey and at the departure station.
  • the invention has been illustrated by choosing the variant according to which the vehicle is of the type with wheels with non-parallel axes, but the invention also applies to the case where the lift orqanes are pads (parallel or different) as well as 'in case the lifting organs are wheels with parallel axes.
