Definitions

  • the present invention relates to the opening and closing control of the doors of vehicles, such as cable transport cabins, and it relates more particularly to a door opening and closing mechanism which ensures locking in the position of closing while tolerating a certain crack.
  • Passenger cable transport installations in particular ski lift installations, are moving in the direction of an increase in passenger flows. This leads to the loading of vehicles in motion and therefore results in very special conditions with regard to the security of closing and opening the doors of these vehicles. Thus, it happens that during the closing of the doors of the cabin, after loading, any object is stuck which prevents the locking of the doors with the risk that they will then open unexpectedly under the action of any parasitic force.
  • Document FR-A-2467124 discloses a door opening and closing mechanism with the possibility of half-opening of the latter in the closed position comprising between a rotating control member and a movable door actuator, a spring connecting rod attached at an eccentric point on said rotating control member and making it possible to lock said door.
  • the main object of the present invention is to provide a mechanism for opening and closing doors, which ensures the locking of the latter in the closed position while allowing the doors to be ajar in the closed position under the effect for example of the jamming of any object, with constant and controlled effort of the jamming, without compromising the locking.
  • the mechanism according to the invention is completed by a safety clutch device which determines the admissible safety threshold with regard to the ajar of the doors.
  • the door opening and closing mechanism comprises, associated with each door, a connecting rod, one end of which is fixed at an eccentric point of a rotary control member driven in rotation by a control lever. opening and closing and the other end of which is fixed at an eccentric point of a movable drive member acting on the door by means of pivoting rods, the locking of the door in the open position as in the position of closing being ensured by a bracing of the connecting rod on either side of a median position of equilibrium.
  • the connecting rod comprises a pneumatic spring which provides a constant force on the ends of the rod fixed to the control and drive members, whatever the linear position of these ends.
  • a dog clutch system is associated with the closing and opening mechanism of the doors to ensure safety in the locked closing position of the doors, and to determine the tolerated opening of the doors. The unlocking of the doors, then their opening, being possible only after disengaging the dog clutch system by actuation of an appropriate control.
  • 1, 1 ′ shows the two door leaves of a cabin which, in the complete closed position shown in FIG. 1, are practically contiguous.
  • Each leaf 1 is connected, by a pair of parallel links 2, 3, to a vertical shaft 4 mounted to rotate in bearings 5 of the chassis of the cabin.
  • a bent guide rod 6, articulated at one end at 7 to the leaf 1, is pivotally mounted at its other end around an axis 8.
  • the shaft 4 is integral, at its upper part, with a toothed pinion 9 which meshes with an operating pinion 10 mounted in free rotation around an axis 11 of the chassis of the cabin.
  • the operating pinion 10 is connected by an air spring 12 to a control pinion 13 secured to a control lever 14.
  • the pneumatic spring 12 comprises a cylinder 15, the bottom of which is secured to a rod 16 articulated at a point eccentric 17 of the pinion 10, inside which can move a piston whose rod 18 is articulated at a point 19 eccentric of the control pinion 13.
  • the pinion 13 meshes with a pinion 13 ′ which, by a kinematic chain 12 ′, 11 ′, 9 ′, 4 ′, 3 ′, 2 ′ identical to the kinematic chain 12, 11, 9, 4, 3, 2, controls the movement of the leaf 1 ′.
  • a pivoting lever 21 which is integral with a movable dog clutch bar 22.
  • This bar 22 has at its central part a notch 23 intended, in a lowered position of the bar, to come cap with a certain play the bent rods 6, 6 ′ in the closed position of the leaves 1, 1 ′ of the cabin door.
  • each of the two leaves is ensured automatically by the corresponding connecting member constituted by the pneumatic spring 12, 12 ′, when the point of attachment 19, 19 ′ to the pinion 13, 13 ′, having passed the point of equilibrium designated at 24, 24 ′ on the X axis, X ′, has an irreversible bracing under the action of a force F applied to the leaf 1, 1 ′ in the direction of its opening.
  • the lever 21 is lowered to cover the links 6, 6 ′ by the notch 23 of the dog clutch 22, acting as a safety device to prevent the rotation of these links in the direction of opening of the leaves.
  • the size of the jammed object 25 causes the leaves 1, 1 ′ to open slightly, which corresponds to a spacing of the rods 6, 6 ′ not exceeding the width e of the notch 23 of the interconnection bar 22. This opening does not therefore prevent the installation of the bar 22.
  • the size of the object 25 ′ wedged between the leaves 1, 1 ′ is such that the opening of these leaves corresponds to a spacing of the rods 6, 6 ′ greater than the width e of the notch 23 of the dog clutch bar 22, this bar can no longer come over the connecting rods 6, 6 ′ to ensure their locking and the safety threshold admissible for the spacing of door leaves is then crossed.
  • the device according to the invention is completely symmetrical with respect to the vertical axis YY ′ of FIGS. 1 to 3. This therefore allows the operation of both a single leaf door and of a door with two leaves. In the latter case, the two leaves may be joined or else cooperate with an intermediate element.
