Definitions

  • Passenger cable transport installations in particular for ski lifts, are moving in the direction of a large increase in the number of passengers in a given time, that is to say a large increase in the throughput of transport.
  • the improvement in throughputs requires vehicles which must allow the rapid loading and unloading of the greatest possible number of passengers in a cabin volume as small as possible compatible with the possibilities of the installation comprising vehicles, which leads to the use of large access cabins, in particular through a door with two leaves which can open along the bodywork, either inside or outside this bodywork.
  • Document FR-A-2 240 133 from the same applicants has proposed a mechanism for actuating the two sliding door leaves, symmetrical with respect to a vertical plane, fitted to a cable passenger cabin.
  • This actuating mechanism comprises a pivoting control part which actuates a practically horizontal toggle lever with crossing of neutral point, which is composed of two symmetrical rods each actuating a lever connected to one of the leaves by an articulated arm.
  • Each lever, at its end opposite the articulated arm, can have a limited displacement in an oblong slot against the action of a return spring.
  • Such a mechanism ensures the irreversibility of the locking of the doors in the closed position, but allows a certain cracking of the leaves under the effect of an obstacle wedged between a leaf and the fixed wall.
  • the present invention relates to an opening, closing and locking mechanism ensuring the irreversibility of the locking while tolerating a certain opening of the leaves under the effect of an obstacle wedged between these leaves without compromising the locking provided by the irreversibility of the control in the closed position which opposes the opening operation under the action of any parasitic force exerted on the leaves.
  • Its essential purpose is such a mechanism, the elements of which work strictly in a horizontal plane, despite the use of the usual lever control system actuated by inclined ramps and pivoting in a vertical plane, avoiding torsional stresses and which can be used without risk of jamming in cabins carrying standing passengers (therefore with very high leaves) because it allows simultaneous actuation of the top and bottom of the door.
  • the mechanism for actuating a door with two leaves which are symmetrical to each other by reference to a vertical plane and mounted on a cable passenger cabin comprises, at one of the ends of the height of the leaves, a pivoting control lever actuating a horizontal knee lever with crossing neutral point composed of two symmetrical rods which actuate two levers connected at least to two movable arms each connected to one of the two leaves, an elastic mounting being provided between each leaf and the associated rod to allow, in the closed position, a limited movement of each leaf towards its open position and consequently the half-opening of the leaves in the closed position locked by the position of the toggle brought to- beyond its neutral point, and it is characterized in that the pivoting lever acts on the rods by means of a control part which has a horizontal movement l parallel to the vertical plane of symmetry of the two leaves, said control part being integral with a crank pin which actuates said toggle joint.
  • the command defined above can be at the top or bottom of the door, but one can also provide two identical commands provided respectively at the top and bottom and connected together by a vertical transmission.
  • the single control can act on a vertical transmission means capable of actuating at the bottom of the door a locking allowing limited opening.
  • each leaf can be a pivoting movement in an arc around a vertical axis around which the leaf actuation lever pivots.
  • each leaf can be secured to two arms of different lengths pivoting in a horizontal plane around different vertical axes while the control lever of this leaf is then connected by elastic connection to one of these arms.
  • the invention can be applied, by doubling the actuation mechanisms, to two opposite doors, each with two leaves.
  • the two actuation mechanisms can then be arranged symmetrically with respect to a vertical plane of symmetry between the two doors. There are then on the same vehicle two access and exit passages through half of the vertical surfaces of the vehicle body.
  • FIG. 1 there is indicated at 1 the vehicle chassis with a door with two leaves 2 - 3.
  • a control lever 4 secured to a lever 5 pivoting on the fixed horizontal axis 6 is provided, in the example shown, with a toothed sector 7 meshing with a rack 8 carried by a control piece 9 with rectilinear horizontal movement parallel to the vertical plane of symmetry passing between the two leaves.
  • This control part carries another rack 10 with vertical teeth meshing with the teeth of a horizontal pinion 11 carried by the upper end of a vertical transmission shaft 12 which carries at its base a horizontal pinion 13 identical to the pinion 11 and meshing with the rack 14 of a lower control piece 15 identical to the upper control piece 9 and driven in a parallel movement in the same direction.
  • the two control parts 9 and 15 drive the two leaves 2 - 3 respectively at the top and at the bottom by identical means which will only be described below for controlling the leaves from above.
  • a crank pin 16, integral with the control piece 9 acts on two identical rods 17 - 18 articulated with two symmetrical levers 19 - 20 in rotation around fixed vertical axes 21 - 22 integral with the chassis 1 and constituting the axes of rotation of the two leaves 2 - 3.
  • the lever 19 is connected to the radial arms 23 - 24 secured to the leaf 2 by an elastic connection shown on a larger scale in FIG. 4 and the lever 20 is similarly connected to the radial arms 25 - 26 secured to the leaf 3.
  • the arms 23 to 26 can bear, at their ends opposite to the fixed pivot axes 21 - 22, by means of bearings 27 - 28 on a raceway 29 secured to the chassis and thus supporting the weight of the two leaves 2 - 3.
  • the elastic coupling shown in FIG. 4 between a lever 19 and the arms 23 - 24 consists of a rod 30 secured to the lever 19 and passing through the arm 23 in a hole with large clearance to allow a certain o scillation of the arm 23 relative to this rod 30.
  • the oscillation is limited, in the example shown, by a nut 31 and controlled in the opposite direction by the pressure of a spring 32. This device allows, on the one hand, adjusting the positioning of the ends of the arms 23 to 26 but also a contact pressure between the two leaves in the closed position.
  • This elastic device also makes it possible to tolerate a certain cracking of the leaves 2 - 3 under the effect of an obstacle wedged between these leaves without detracting from the locking explained below.
  • the nut 31 could be replaced by a spring allowing the arms 23 to 26 to oscillate in both directions in the locked closed position.
  • control of the leaves is only carried out by their upper end under the action of the control piece 9 without the use of a control piece at the bottom. It will be noted that one could also use only a control of the leaves from the bottom without control from the top.
  • This lever 36 pivots between its ends at 37 on a horizontal fixed axis secured to the chassis while its end opposite the rod 34 has the form a T whose crosspiece ends with two hooks intended, in the lowering position of the rod 34, to retain in the locking position of the stops of the two leaves, leaving these leaves the possibility of limited opening.
  • each of the two leaves of a cabin door pivots around a vertical axis in a circular arc movement in a horizontal plane.
  • two symmetrical leaves 39 - 40 whose lateral edges 41 - 42 and 43 - 44 pivot around different vertical axes on which s articulate rotation arms of different lengths.
  • An example of such leaves is shown diagrammatically by the plan view of FIG. 8 in which the lateral edges of the two leaves 39 - 40 located one against the other in the closed position are indicated at 41 - 42 and at 43 - 44 opposite edges.
  • the rotation arms leading to the edges 41 to 44 are indicated from 45 to 48 respectively and the axes of rotation from 49 to 52.
  • the horizontal traces of the ends of the arms are shown in broken lines and in 41 'to 44' the positions of the edges of the leaves when these leaves have been brought into the open position, while FIG. 8 schematically shows them in the closed position.
