Patent number: 9783392Abstract: An elevator door stopping device which can prevent that elevator door is closed by itself when power supplied to a motor for opening and closing the elevator door is interrupted, an improvement of the elevator door stopping device characterized in that a first magnetic body is fixed on a shaft rotating in interlock with opening and closing of the elevator door so as to generate a magnetic force in a radial direction perpendicular to the shaft, and a second magnetic body is fixed on a fixed face spaced apart from the first magnetic body at a predetermined interval in the radial direction in such a manner that the second magnetic body has the opposite pole to the first magnetic body, so that a magnetic force is generated between the first magnetic body and the second magnetic body in the radial direction perpendicular to the shaft.Type: GrantFiled: September 12, 2013Date of Patent: October 10, 2017Assignee: OTIS ELEVATOR COMPANYInventors: Jung Sam Kim, Jinkoo Lee, Hansoo Shim, JinKyu Ryu

Patent number: 9731941Abstract: A device for inhibiting the closing of a door that controls entry of an enclosure includes a first magnet disposed on a driven portion of the device and a second magnet disposed on a fixed portion of the enclosure. The first magnet and the second magnet are configured to be in register with each other as the door moves toward a closed position such that if the first magnet and the second magnet are in register with each other, a pole of the first magnet is in close proximity of a pole of the second magnet such that the first magnet and the second magnet react to each other to inhibit motion of the door towards the closed position.Type: GrantFiled: November 30, 2010Date of Patent: August 15, 2017Assignee: Otis Elevator CompanyInventors: Jinkoo Lee, Jung Sam Kim, Byeong Sam Yoo, Hansoo Shim, Guohong Hu, Mark Steven Thompson

Patent number: 8434599Abstract: A separation distance is maintained between a leading elevator car (14) and a trailing elevator car (12) traveling in the same direction in an elevator hoistway (16). A shortest stopping distance (dssl) of the leading elevator car (14) and a normal stopping distance (dnst) of the trailing elevator car (12) are determined. The separation distance (dsep) is controlled such that a difference between the normal stopping distance (dnst) of the trailing elevator car (12) and the shortest stopping distance (dssl) of the leading elevator car (14) is greater than or equal to a threshold distance (dthresh).Type: GrantFiled: September 18, 2007Date of Patent: May 7, 2013Assignee: Otis Elevator CompanyInventors: Cheng-Shuo Wang, Arthur C.

Patent number: 8297409Abstract: The movement of a plurality of elevator cars (12, 14) in an elevator hoistway (16) is coordinated for situations in which the regions of the hoistway that are serviceable by the cars (12, 14) at any given time are configured to overlap. A car stop plan for each elevator car (12, 14) is generated that includes a sequence of stops for servicing demand assigned to the elevator car (12, 14). Operation of the elevator cars (12, 14) is then coordinated based on the car stop plans such that each elevator car (12, 14) services its assigned demand without interfering with the car stop plans of any other of the plurality of elevator cars (12, 14).Type: GrantFiled: November 30, 2007Date of Patent: October 30, 2012Assignee: Otis Elevator CompanyInventors: Arthur C. Hsu, Cheng-Shuo Wang, Hansoo Shim, Cheong Sik Shin, SeongRak Jeong, Bruce P. Lerner

Patent number: 8136635Abstract: Controlling the movement of elevator cars (22, 24) within a single hoistway (26) prevents the cars from becoming too close while servicing assigned stops. Example control techniques include controlling door operation of at least one of the elevator cars (22, 24) to effectively slow down a follower car or speed up a leader car for increasing a distance between the cars in an area within the hoistway (26) where the cars would otherwise be too close to each other.Type: GrantFiled: December 22, 2006Date of Patent: March 20, 2012Assignee: Otis Elevator CompanyInventors: Theresa M. Christy, Randall Keith Roberts, Harold Terry, Mauro J. Atalla, Arthur C. Hsu, CheongSik Shin, Hansoo Shim

Patent number: 7987947Abstract: Destination calls entered by means of buttons (21-29) are each given a designation unique to the car and pick-up floor for that call and other calls to be serviced therewith, such as a letter (A-E), which is different from any other outstanding calls. Calls can be reassigned among elevators (UL, LL, UR, LR) whether they are in the same or different hoistways (LF, RT). Signs (31-39, 41-49) adjacent each hoistway are illuminated to display the designation of any call which is being answered by an elevator car approaching the floor. Thus, passengers are informed when their call is being answered by the signs identifying the call, rather than identifying any particular car. Another embodiment identifies (60, 31a, 41a) the hoistway landing doorway (1, 2) as well as a letter to allow passengers to wait adjacent to the hoistway landing doorway of the car which will serve them.Type: GrantFiled: December 15, 2005Date of Patent: August 2, 2011Assignee: Otis Elevator CompanyInventors: Theresa Christy, Jannah Stanley, Hideyuki Honma, Arthur Hsu, John M.

Patent number: 7784588Abstract: A method of assigning destination calls to cars (A-F) in an elevator system (20) having a plurality of hoistways (21-23) in which there is more than one car in each hoistway includes determining (33) the time for each car to respond to the call Among the cars with an acceptable response time, a determination is made regarding (34) the amount of additional delay in the hoistway that assignment of the call to one car will impose on the either car in the same hoistway. The call is assigned to that car which creates the least additional delay for cars in any hoistway.Type: GrantFiled: February 4, 2005Date of Patent: August 31, 2010Assignee: Otis Elevator CompanyInventors: Cheong SikShin, Theresa Christy, Arthur Hsu, Hansoo Shim, Harry Terry

Disclosed example techniques also include dynamically altering the motion profile of at least one of the cars and adding an additional stop for one of the cars.Type: ApplicationFiled: December 22, 2006Publication date: March 18, 2010Inventors: Theresa M.

Patent number: 7650967Abstract: One of a plurality of cars (17, 18) traveling in a hoistway (10) of an elevator system (9) may be diverted to the hoistway overhead (31) or pit (36) to enable another of the cars to gain access to a floor near or at a terminal floor (11, 14). When such car is at its last stop with doors open, visual (40) and audible (41) indicators present (57, 58) messages to the effect that this is the last stop and passengers should exit. After car doors are closed (66), visual and audible messages (68, 69) relate to the car going to the pit or overhead and that passengers may push any button (to reopen doors). Thereafter, the car moves (75, 76) to the overhead (31) or the pit (36) and presents (82, 83) visual and audible messages to the effect that passengers did not exit at the correct floor and must wait while the other car makes a stop.Type: GrantFiled: February 17, 2005Date of Patent: January 26, 2010Assignee: Otis Elevator CompanyInventors: Cheong SikShin, Theresa Christy, Arthur Hsu, Hansoo Shim, Harry Terry, Frank Sansevero
