摘要： An elevator safety chain includes a plurality of passive radio frequency identification devices (RFIDs) (15-18, 22, 34-36 and 63), which are associated, respectively, with hoistway door locks, upper hoistway limits, lower hoistway limits, overspeed detection, car door lock, emergency stop switch, and inspection switch. RFIDs may be associated with car call buttons (34) and/or hall call buttons (14, 19). The RFIDs may have a switch (43, 44) in the frequency-determining circuitry (40, 41) which defeats the RFID's ability to respond, or a switch (48) which alters the responding frequency. The RFIDs may sense safe or unsafe conditions, or call requests, by either the presence of absence, or vice versa, of adjacent magnetic reluctance (51, 62, 71).

摘要： A brake mechanism (10) for an elevator (2) is activated in response to an electronic control signal to prevent movement of an elevator car (16) under predetermined conditions. The brake mechanism is preferably a safety mechanism (10) and does not require a governor sheave, a governor rope, or a tension sheave. The safety mechanism in one disclosed example utilizes a solenoid actuator (22b) and an electric motor (40) and gear box assembly (42) to move safety wedges (18) into engagement with a guide rail (20) to stop the elevator car (16). The safety wedges (18) are held in a non-deployed position during normal elevator operation. If there is a power loss or if elevator car speed exceeds a predetermined threshold, an electronic control signal activates the safety mechanism (10) causing the solenoid to release, which causes the safety wedges (18) move in a direction opposite to that of a safety housing (12) mounted for movement with the elevator car (16). Angled surfaces of the safety housing (12) force the safety wedges (18) into engagement with the guide rail (20). The safety mechanism (10) can be selectively reset from a remote location.

摘要： Fixtures (22, 27) at a doorway (13) of a landing (14) are formed integrally with a door frame (17, 17a). The fixtures include electronic modules (42, 46, 54) and energy storage devices (43, 47, 55). Power may be supplied by a generator (32) rotated by a pinion (34) in response to a rack (35) on a hoistway door (20), or by electrical contacts (58) disposed on the hoistway side of the door frame which touch contacts (65) on an elevator car door (63) when the door is open, thereby receiving power over a line (66) from the elevator car; or power may be provided by an inductive coupler (70). The fixtures (22, 27) may be within the profile of the door frame (17), or extend outwardly from the profile of the door frame (17a).
