Patent number: 7575099Abstract: 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).Type: GrantFiled: October 7, 2003Date of Patent: August 18, 2009Assignee: Otis Elevator CompanyInventors: Jae-Hyuk Oh, Robin Mihekun Miller, Richard E.

Patent number: 5857545Abstract: An elevator system has a plurality of elevator cars traveling upwardly in one hoistway and downwardly in an adjacent hoistway, the cars being propelled in a series of overlapping segments, each segment including a pair of couplers roped to counterweights and driven by elevator traction machines. A variant uses a closed loop rope with a pair of couplers to transfer elevator cars from a counterweighted coupler of one segment to a counterweighted coupler of an adjacent segment. An upper passenger landing moves cars on overhead trolleys and a lower passenger landing moves cars on dollies to take them from a hoistway through unloading and loading stations and back to another hoistway. The elevator car roller guides are releasable to permit lateral movement of cars to and from landings. A latched spring buffer and/or a LEM decelerate and accelerate unbalanced counterweights.Type: GrantFiled: March 20, 1997Date of Patent: January 12, 1999Assignee: Otis Elevator CompanyInventors: David W.

Patent number: 5808246Abstract: An electronic motor drive produces a required motion profile for an elevator door operator actuated by a three-phase, line-powered linear induction motor (LIM) by means of an array of TRIAC switches producing selected forces from the LIM. The TRIAC drive is capable of producing acceleration, deceleration or free coast in either the open or close direction of door operation. When controlled by an algorithm such as a "time-optimal switch point" or "bang-bang" control, the TRIAC drive produces the required motions from the linear induction motor for elevator door operation. The motor windings may be switchable between delta and wye hookups to provide two distinct thrust levels. Phase angle modulation may be used to provide finer control of thrust.Type: GrantFiled: September 25, 1995Date of Patent: September 15, 1998Assignee: Otis Elevator CompanyInventors: Richard E. Peruggi, Thomas M. McHugh, Edward E. Ahigian, Jerome F. Jaminet, Thomas He, Thomas M. Kowalczyk, Richard E. Kulak, David W. Barrett, Zbigniew Piech

Patent number: 5736693Abstract: A linear induction motor utilizes a double-sided primary and a dual secondary to directly drive an elevator car door open and closed. The invention has the advantage of being compact: all magnetic-attractive loads are confined to a primary mount bracket, and all thrust loads are carried directly by the car header, not transferred to the cab. Also, high thrusts can be developed from a small space, i.e., short net working coil area, due to the double-sided primary winding and dual secondary arrangement. The configuration is basically simple, with a low moving mass and easy-to-fabricate parts, the primary core being particularly easily wound.Type: GrantFiled: September 25, 1995Date of Patent: April 7, 1998Assignee: Otis Elevator CompanyInventors: Zbigniew Piech, Jerome F.

Patent number: 5651428Abstract: A coupling for causing an elevator car door to engage an elevator hoistway door includes a pair of vanes, each end of each vane pivoted on a link connecting it with the other vane, the links being disposed for rotation between said two vanes on an elevator car door thereby forming a parallelogram. The vanes extend vertically between four rollers which rotate about horizontal axles disposed at the top of the hoistway door, and which provide rotationally stiff coupling. A solenoid actuator can move one vane up to cause the parallelogram to shrink, into an uncoupled position. When the actuator is disenergized, a spring causes the parallelogram to spread so that the vanes are wedged between the rollers and the two doors are coupled together.Type: GrantFiled: February 13, 1996Date of Patent: July 29, 1997Assignee: Otis Elevator CompanyInventors: Edward E.

Patent number: 5509504Abstract: An elevator car door is moved by a variable voltage, variable frequency linear induction motor which is driven open current loop to achieve a desired velocity profile indicated by an incremental linear encoder, with washed out proportional and integral gain. A magnetizing current insufficient to overcome the weight of the door is added in quadrature with the linear force current, and frequency is determined open loop in a predetermined fashion. Pulse width modulation voltage control signals are utilized to apply fixed voltages of correct polarity through a low pass three phase filter to the windings of the motor for correct intervals of time so as to synthesize desired sinusoidal winding currents. A boost of current is provided following each zero crossing of the sinusoidal winding currents to overcome lags therein. A ramp down of voltage avoids dropping the door at the end of door opening and door closing.Type: GrantFiled: April 6, 1994Date of Patent: April 23, 1996Assignee: Otis Elevator CompanyInventors: Thomas M.
