Abstract

[0031] AN ELEVATOR DERAILMENT DETECTION SYSTEM (51) IS DISCLOSED WHICH PROVIDES FOR ACCURATE DETECTION OF THE DERAILMENT OF A MOVABLE ELEMENT (30, 32), SUCH AS A COUNTERWEIGHT (32) OR AN ELEVATOR CAR (30), WITHIN A HOISTWAY (22) EVEN WHEN THE BUILDING (24) WITHIN WHICH THE ELEVATOR (20) IS INSTALLED IS OF A SUBSTANTIAL HEIGHT AND MAY BE EXPERIENCING A SIGNIFICANT DEGREE OF SWAY DUE TO HIGH WINDS, EARTHQUAKES, OR OTHER CAUSES. BY MOUNTING AN ELECTRIC CONDUCTOR (52) SUCH AS A SENSING WIRE OF THE SYSTEM (51) AT SPACED INTERVALS (76) ALONG THE LENGTH OF THE HOISTWAY (22), THE ELECTRIC CONDUCTOR (52) IN TURN SWAYS WITH THE BUILDING (24). ACCORDINGLY, CONTACT OF THE ELECTRICAL CONDUCTOR WITH SENSORS ATTACHED TO A MOVABLE ELEMENT WITHIN THE HOISTWAY, SUCH AS THE COUNTERWEIGHT, IS LIMITED TO DERAILMENT SITUATIONS AND NOT NORMAL BUILDING SWAY, AND FALSE TRIPS ARE SIGNIFICANTLY REDUCED. IN ADDITION, BY PROVIDING MOUNTING BRACKETS (60, 62, 64) AND SENSING APPARATUS (66) WITH A NON-CONTINUOUS PERIMETER, THE OPERATION AND MOVEMENT OF THE RESPECTIVE COMPONENTS (30, 32) IS NOT HINDERED BY THIS SYSTEM (51).
