  • the invention relates to elevators and lifts for the transport of people to and from their homes in mecanicd semi-detached houses built on hillsides, or between floors in hotels and other buildings erected on the same priciple.
  • the inclined elevator for brieflyd semi-detached homes is designed for higher speed without the unpleasantness of horizontal inertia forces acting on the passengers.

  • the carriage will travel on rails on the tunnel floor with the cabin suspended from a horizontal axle at the top of a structure erected on the carriage.
  • the pivot from which the cabin is suspended is a horizontal axle with its axis perpendicular to the direction of travel, causing the cabin to swing about this pivot during start and stop periods of the elevator near each station. Deceleration before a stop and complete halt at the station will deviate the cabin about a maximum angle without effect on the passengers.
  • the angular swinging motion of the cabin is controlled by an electrically operated linear actuator connecting a portion of the cabin with the carriage.
  • the actuator is preferably controlled by sensor means sensitive to acceleration and deceleration of the carriage and the cabin, so as to regulate the speed at which the cabin is brought into vertical position again.
  • the sensor may control the actuator by sensing the angular deviation of the ' cabin relative to the carriage, selectively at start and at stop, during uphill and downhill travel.
  • there may be a combination of sensor means of both kinds controllimg the actuator motor speed by means of an electronic controller.
  • the linear actuator it is proposed to mount a rotary actuator in concentric alignment with the pivot axle supporting the cabin, which is to moven the cabin in a direction and at a rotational speed required to obtain minimal inertia forces acting on the passengers.
  • the elevator cabin can be mounted on wheels that travel on an upwardly curved pair of rails which form the top portion of a carriage running on rails on the tunnel floor.
  • the curvature has a focus non the vertical canterline of the cabin, and it becomes evident that the inertia forces would force the cabin to travel up and down the curved rails while rotating about the focus.

  • Figure 4 is a schematic side view of an inclined elevator having the cabin supported in a curved cradle.
  • the inclined elevator shown in Figures 1 and 2 travels on rails 16 which are attached to the top 1 of a tunnel or an inclined shaft by a support structure 17.
  • the elevator cabin 2 is suspended from a wheeled carriage 15 by means of a horizontal pivot in the form of an axle 3 which permits angular motion in forward and rearward direction as indicated by angle 6.

  • the pivotal suspension of the cabin has been chosen with a view to reducing the horizontal inertia forces on the passengers during stops and starts of the elevator.
  • the cabin would swing pendulum-like at every stop until coming to a final rest, a feature to be avoided by the provision of a linear actuator 8 connecting a point on the cabin with a point on the carriage.

  • Sensor 19 (or 29)is mounted on the carriage and measures the acceleration of the carriage and signals are transmitted to and from the control system of the elevator assembly. At zero acceleration the cabin should be in vertical position as recorded by sensor 20 on top of the cabin.
  • Sensor 18 at the cabin's bottom measures the acceleration perpendicular to the passengers' bodies, which is to be reduced to a minimumm by action of the ctuator.
  • the center of gravity of an adult person- about 0.8 m above the floor - and the sensor could advantageously be mounted on the cabin at that level.
  • the actual acceleration at this level is readily calculated by the control system.
  • the signals emitted by the sensors are transmitted to the control system which is programmed to calculate the optimum angle for a minimum acceleration force on the passengers. Then it measures the actual angle 6 by means of sensor 20 and corrects any deviation from the desired condi tion.
  • the senor can be omitted and the actuator motion pre-designated and programmed. It is evident that owing to the backwards swinging of the cabin during starting and forward tilting during stopping of the elevator the inertia forces on the passengers are mainly in vertical direction and therefore not disturbing. On the other hand, Tightening of the cabin from tilting position, especially the last phase will cause horizontal forces trying to push people sidewards. It is, therefore the task of the actuator to provide smooth landing of the cabin into vertical position by controlling the speed to be gradually reduced at the end of the return path.

Abstract

Cet ascenseur à trajet en pente, reliant les étages d'habitations en terrasse et jumelées, et conçu pour réduire les forces horizontales d'inertie, afin que celles-ci ne gênent aucunement les passagers lors des arrêts et des démarrages, comprend une cabine suspendue de manière pivotante à un chariot se déplaçant sur des rails dans un axe ou tunnel. La balancement du chariot, lors de chaque arrêt ou démarrage, est limité par un actionneur linéaire reliant de façon pivotante des points respectifs de la cabine et du chariot, par régulation de la vitesse angulaire de la cabine à partir de la déviation de celle-ci par rapport à sa position verticale, lors des arrêts ou démarrages. Le déplacement linéaire de l'actionneur est commandé par des capteurs mesurant, d'une part, l'accélération et la décélération du chariot et, d'autre part, la déviation angulaire de la cabine par rapport à la position verticale de celle-ci. Des signaux sont transmis en continu, à partir des capteurs et en direction d'un module de commande électronique, lequel commande la vitesse et la position de l'actionneur linéaire et donc la vitesse angulaire de la cabine, afin que les passagers, debout dans la cabine, subissent un minimum de forces d'inertie horizontales.
