摘要： An elevator system is capable of detecting that a car has overshot a position where a limit switch operates. The elevator system includes: a limit switch; a conductive wire provided along a guide rail guiding movement of a counterweight; a contact being attached to the counterweight and moreover configured to come into contact with the conductive wire in a case where the counterweight is disconnected from the guide rail; an overshoot detection contact being attached to the conductive wire and disposed at a position that allows the overshoot detection contact to come into contact with the contact in the case where the car moves past a position where the limit switch operates; and an overshoot detection unit configured to detect that the contact is in contact with the overshoot detection contact.

摘要： Elevator systems having a first guide rail and a second guide rail, an overtravel feature on at least one of the first or second guide rails, the overtravel feature located a first distance from a top surface of the respective guide rail, an elevator car moveable along the first and second guide rails, the elevator car including a car guidance element, and a control unit configured to perform an overtravel distance test. The control unit is configured to measure a second distance being a distance of travel of the elevator car between a landing position and a location of the overtravel feature, combine the first distance and the second distance to calculate a measured overtravel distance, and compare the measured overtravel distance with a predetermined overtravel setpoint.

摘要： A method and apparatus for the generation of elevator car position information in an elevator shaft includes a safety light barrier mounted on the car and actuating vanes in the shaft cooperating with a safety circuit for connecting the door and lock contacts to a source of electrical power in the door zone of a destination floor for a stopping elevator car. The safety light barrier has two transmitters and two receivers which are positioned on a horizontal line and are masked simultaneously by the actuating vanes. The safety circuit includes two redundant systems for signal preparation and signal evaluation including test circuits to recognize errors and prevent a premature opening of the elevator door.

摘要： An elevator system including an elevator car mounted for movement in a building to serve the floors therein, including upper and lower terminal floors. The speed of the elevator car is checked or monitored at predetermined positions of the elevator car as it is approaching either terminal to insure that the car is slowing down within the limits of a predetermined deceleration schedule. A new and improved low inertia, fast acting car speed sensor insures that the speed indication used by the supervisory control is correct and timely at each car position check point, within a predetermined small tolerance.

摘要： An elevator safety device in which a counterweight cam is attached to the counterweight and top terminal landing final limit switches are disposed below the bottom terminal landing of the hoistway so that it is operated by the counterweight cam. The top terminal landing final limit switches only need to be provided in accordance with the counterweight buffer stroke, regardless of to what extent the car has been flung upward, with the result that fewer final limit switches are required.

摘要： A floor selector comprises a first and a second switch on an elevator car, a vertical array of first switch actuators each disposed between each pair of adjacent floors in a hoistway, and another vertical array of second switch actuators located below the first actuators in the hoistway. When the first switch engages each of the first actuators, a synchronized floor is renewed by adding one floor to the preceding synchronized floor read out from an RAM by a micro-processor and written into the RAM. When the second switch engages each of the second actuators, an advanced floor in advance of the synchronized floor is renewed by adding two floors to the preceding advanced floor read out from the RAM by the micro-processor and written into the RAM.

摘要： An elevator system including an elevator car mounted in a structure to serve the landings therein, and an opto-electronic position detector for determining when the elevator car is within a predetermined distance from a selected landing. The position detector includes a source of electromagnetic radiation which is pulsed at a predetermined rate, such as a light emitting diode, and a photovoltaic device which provides an output current having a magnitude responsive to the level of the electromagnetic radiation it is subjected to, such as a photo transistor. The source of electromagnetic radiation and photovoltaic device are mounted in a common housing with a beam splitter, such as a half-silvered mirror, and this assembly is preferably mounted on the elevator car. A control device or target is mounted adjacent each landing to be served by the elevator car, with the control device including a retrodirective reflective surface or retroreflector. The housing is oriented such that the angle of incidence of a beam of electromagnetic radiation provided by the source of electromagnetic radiation strikes the retrodirective surface with an angle other than 90.degree.. The photovoltaic device is electrically biased to provide an output current regardless of the level of the electromagnetic radiation applied to the photovoltaic device. When the photovoltaic device receives electrical radiation, such as from the retrodirective surface, its output current changes, and means responsive to changes in the output current energizes a translating device when the output current changes at a rate indicating the photovoltaic device is receiving the pulsed electromagnetic radiation from the source thereof.
