Abstract
In an aerial transport system in which a carriage approaches a station or other fixed parts of the system, a device for stabilizing the carriage as it approaches the station or the other parts, comprising a pair of outward-facing bumping elements on the carriage, and a pair of bars in a V-shape, open towards the direction of approach of the carriage, in between which the bumping elements enter and are restricted as the carriage approaches the station and the other parts. The bars are supported so that they can be moved apart by the impact of the bumping elements, against a resilient restoring force.
Claims19
A stabilizing device for an aerial carriage travelling along an aerial cableway comprising:
- a pair of bumping elements vertically protruding from the bottom of said carriage, said bumping elements being arranged in alignment transverse with respect to the longitudinal axis of said carriage and apart from each other to define therebetween a space;
- a pair of guide bars defining an approximately horizontal V-shape opening towards the direction of approach of the carriage, said guide bars being collidable with said bumping elements and movable from initial positions to other positions farther away from each other upon collision with said bumping elements;
- and
- means for biasing said guide bars to said initial positions thereof, which biasing means damp the colliding force applied by the collision of the bumping element with said guide bar.
A stabilizing device for an aerial carriage travelling along an aerial cableway comprising:
- a pair of bumping elements on the carriage, facing generally outwards away from one another;
- a pair of rigid guide bars defining an approximately horizontal V-shaped passageway for said carriage through which said bumping elements pass upon approach to a station, each of said guide bars being movable between an initial position relative to the other guide bar and a moved position moved away from the other guide bar;
- means for biasing each of said guide bars to said initial position with a resilient force against the impact of collision of said bumping elements and said guide bars;
- and
- means, incorporated in said biasing means, for absorbing the force of impact to stabilize the rolling of the carriage.
A stabilizing device for an aerial carriage travelling along an aerial cableway comprising:
- a pair of bumping elements protruding vertically from the bottom of the carriage in parallel relationship with respect to one another, said bumping elements being located in transverse alignment with respect to the longitudinal axis of the carriage and in spaced apart relationship to define therebetween a substantially narrow space;
- a pair of angled rigid guide bars respectively pivoted about a stationary member at the end of the guide bar remote from an approaching carriage, said pivoted ends of the guide bars being spaced for permitting said bumping elements to pass therethrough and adapted for restricting the lateral motion of the bumping elements, said guide bars being movable about said stationary member between an initial position in which said guide bars define an approximately horizontal V-shaped passageway for permitting said bumping elements to pass therethrough, and a moved position in which one of said guide bars is moved from said initial position away from the other guide bar when the bumping element adjacent said one guide bar collides therewith;
- means for biasing said guide bars to said initial position against the force applied to one of said guide bars when the adjacent bumping element collides therewith, said biasing means acting to restore said one guide bar to its initial position against the colliding force;
- and
- means, incorporated in said biasing means, for absorbing a force which causes rolling of the carriage.
In a transport system having a hanging carriage which travels along an aerial tramway or cableway, a system for roll-pitch-stabilizing the carriage as it approaches thereto, comprising:
- a pair of outward bumping elements on the carriage, facing generally outwards away from one another;
- a pair of inward bumping elements on the carriage, facing generally inwards towards one another;
- a pair of downward bumping elements on the carriage, facing generally downwards, and spaced along an axis in the same vertical plane as the general direction of motion of the carriage;
- a pair of angled rigid bars, mounted to stationary members in such a manner that they can be moved apart against a resilient restoring force, each of said bars having a first straight portion and a second portion at an angle to the first straight portion, the ends of the first straight portion and the second portion being joined, the two second portions of the two bars together defining an approximately horizontal V-shape opening towards the direction of approach of the carriage to said stabilizing system, and the two first straight portions extending from the narrow end of the V-shape away from the direction of approach of the carriage in parallel side by side relationship at a distance apart great enough for the pair of outward bumping elements to enter between them;
- and
- a stationary bar extending from the ends of the first straight portions which are away from the direction of approach of the carriage thereto to a point removed from the ends of the first straight portions in the direction away from the direction of approach of the carriage.
A method for stabilizing an aerial carriage travelling along an aerial cableway comprising:
- resiliently limiting the lateral motion of the carriage about a rolling axis thereof, and gradually reducing the lateral spacing in which the lateral motion of said carriage is being limited;
- absorbing the force causing the lateral motion of the carriage and stabilizing the rolling motion of the carriage;
- guiding the carriage along said cableway so that it may not move in the lateral direction with respect to the rolling axis thereof;
- and
- restricting pitching motion of the carriage about the pitching axis thereof.
