Ein weiterer Aspekt der Erfindung betrifft eine Aufzugseinrichtung (10) mit der genannten Entriegelungsvorrichtung (1) und ein Verfahren zum Betätigen der Entriegelungsvorrichtung (1).
Abstract:
An elevator car system and method for operating elevators doors includes an elevator car having a door capable of opening and closing along a pathway and an interior portion internal to the door, a first obstruction sensor disposed on the door capable of detecting an obstruction in the pathway of the door, and a supplemental obstruction sensor disposed in the interior portion of the elevator car system capable of detecting an obstruction in an area adjacent to the door, wherein the door opens or closes based on the detection of the first obstruction sensor or the detection of the second obstruction sensor. The interior portion of the elevator car may include a recessed channel, with the supplemental obstruction sensor being disposed in the recessed channel.
Abstract:
Eine Überwachungsanlage (1) für Personentransportanlagen (2), die als Aufzug, Rolltreppe oder Fahrsteig ausgestaltet sind, umfasst zumindest eine Abfrageeinrichtung (20) und zumindest eine über einen elektrischen Sicherheitskreis (22) mit der Abfrageeinrichtung (20) verbundenen Sicherheitsschalter (21), der zur Überwachung eines Türschlosses (3) der Personentransportanlage (2) dient. Hierbei ist eine unabhängige Energieversorgungseinrichtung (30) vorhanden. Die Abfrageeinrichtung (20) ist von der unabhängigen Energieversorgungseinrichtung (30) versorgbar. Ferner ist eine Personentransportanlage (2) mit solch einer Überwachungsanlage (1) angegeben.
Abstract:
An exemplary system includes a moveable mass. A load bearing member includes at least one electrically conductive tension member that supports a load associated with movement of the mass. An electrically conductive member is situated along a selected portion of a path of movement of the load bearing member. The electrically conductive member is not subject to a load on the tension member. A processor is configured to determine an electrical resistance of the tension member as an indicator of a condition of the tension member. The processor is configured to determine an electrical resistance of the electrically conductive member. The processor uses the determined electrical resistance of the electrically conductive member to compensate for any environmental influence on the determined electrical resistance of the tension member.
Abstract:
An electromagnetic door lock assembly (30) includes a first portion (32) supported relative to hoistway doors (22) and a second portion (34) supported for movement with an elevator car (24). The first and second portions cooperate so that electromagnetic interaction between them unlocks a set of hoistway doors (22) for access to the car (24), for example. In disclosed embodiments, a first portion (32) of the actuator has at least one stationary electromagnetic portion (36A, 36B) and at least one moveable portion (38). The second portion (34) that moves with the car (24) includes at least one stationary electromagnetic portion (44). Magnetic interaction between the first and second portions (32, 34) causes selected movement of the moveable portion (38) for selectively locking or unlocking the doors (22).
Abstract:
A method of detecting unauthorised access to an elevator hoistway comprises receiving a signal indicative of a landing door opening (2) and determining whether the elevator car door is closed (4). If the car door is determined to be closed, A determination is made as to whether the load on the car is above a predetermined threshold (8) and if so normal operation of the car is suspended (10). If the load is below the threshold normal operation is suspended after a delay to allow safety verifications (12). A determination may be made as to whether there are two landing doors open simultaneously (14) and if there are normal operation is suspended (10).
Abstract:
A retractable stair assembly built into the car (5) of a lift (50) controlled from inside said car, whereby one of the floors (1, 2) of a building may be accessed over a railing (3) or equivalent obstacle. The stair assembly consists of an intermediate gangway (11) and access stairs (6) hingedly interconnected and controlled by a handle located inside the lift car or by any mechnical and electrical control device providing absolute system safety. Landing doors are therefore no longer necessary. The device is particularly suitable for use in outdoor lifts on building sites or for protecting people as they get in and out of vehicles.
Abstract:
An elevator car door safety device that uses flags along a hoistway is disclosed. The elevator car door safety device is mounted to the outside of an elevator car door using a mounting plate and includes a locking assembly mounted to the sill of the elevator car door. The car door safety device includes a lever with a hook at its distal end. The safety device also includes a flag engagement arm perpendicularly mounted to the lever. If the flag engagement arm engages a flag on the hoistway then the hook is prevented from being lodged into the locking assembly and the car door is permitted to open. Inversely, if no flag is engaged, the lever will continue to rotate urging the hook to be lodged within the locking assembly, thereby preventing the door from opening. An electric switch assembly can be used to stop the motion of the elevator.
