  • Patent number: 4655144
    Abstract: A passenger cabin for an aerial cable railway or the like is constructed from outwardly convex panels connected at their adjoining edges by hollow profile sections. One sidewall of the cabin is equipped with a door. Sensing members of the cabin engage control members of the cable railway stations and transmit a control motion to a door actuation mechanism within the floor construction of the cabin. A crank operates a rocker arm which drives two connecting rods. Racks arranged on the connecting rods drive sector gears mounted on the cabin and cause pivot arms connected with each leaf of the door to pivot. The pivot arms cause the doors to translate along and pivot conjointly with guide rails hinged at their common center. The door leaves can therefore be flush with the sidewall of the cabin in the closed position and require a minimum of space in opening.

  • Patent number: 3971324
    Abstract: A cable transport system for cabins wherein at each station there are secured two control rails and wherein each cabin comprises a door which, in its closed condition, is locked by a locking mechanism, the door being operatively connected with an actuation lever at which there engages one end of a tensioning device which in an intermediate position of the door intersects an extension of the axis of rotation of the actuation lever. A feeler element is connected with a control element, the feeler element, upon scanning the control rails, moving the control element from one terminal position into another terminal position, the door being opened in one terminal position and closed in the other terminal position. The control element comprises a carriage which can be displaced along a guide rail fixedly connected with the cabin.
