Patent number: 10214391Abstract: The present invention provides a handrail entry monitoring system of a passenger conveyor and a monitoring method thereof, and belongs to the field of passenger conveyor technologies. In the handrail entry monitoring system and the monitoring method of the present invention, at least part of a handrail entry region of the passenger conveyor is sensed by using an imaging sensor and/or a depth sensing sensor, to acquire a data frame, and the data frame is analyzed to monitor whether a handrail entry of the operating passenger conveyor is in a normal state or an abnormal state. The monitoring system of the present invention and the monitoring method thereof can timely and effectively detect a danger that a foreign matter is about to be entrapped into the handrail entry, helping prevent foreign matters from being entrapped into the handrail entry, thereby improving safety of the passenger conveyor.Type: GrantFiled: July 28, 2017Date of Patent: February 26, 2019Assignee: OTIS ELEVATOR COMPANYInventors: LongWen Wang, ZhaoXia Hu, Hui Fang, Zhen Jia, Jianwei Zhao, Qiang Li, Anna Su, Alan Matthew Finn, Gero Gschwendtner

Patent number: 10071884Abstract: The present invention relates to the field of passenger conveyor technologies, and provides an engaging state detection system of a passenger conveyor and a detection method thereof. In the engaging state detection system and detection method of the present invention, a depth sensing sensor is used to sense at least an engaging portion between a step and a comb plate of the passenger conveyor to obtain depth maps, and the depth maps are analyzed by a processing apparatus to detect whether an engaging state between the step and the comb plate is a normal state. The detection of the engaging state includes detection on whether comb teeth of the comb plate are broken, whether engaging teeth of the step are broken, and/or whether a foreign matter exists on an engaging line.Type: GrantFiled: July 28, 2017Date of Patent: September 11, 2018Assignee: OTIS ELEVATOR COMPANYInventors: JianGuo Li, Nigel Morris, Alois Senger, Jianwei Zhao, ZhaoXia Hu, Qiang Li, Hui Fang, Zhen Jia, Anna Su, Alan Matthew Finn, LongWen Wang, Qian Li, Gero Gschwendtner

Patent number: 9272882Abstract: A system for detecting a person relative to a passenger conveyor includes a driving circuit for supplying an oscillating drive signal to a first electrode of a capacitive sensor configured to produce an electric field toward a second electrode in response to the oscillating drive signal. A detection circuit is connected to the capacitive sensor, and produces an output as a function of the capacitance of the capacitive sensor, such that the detection circuit senses a change in capacitance of the capacitive sensor, such as when a person enters the electric field between the first and second electrodes. A controller is responsive to the change in capacitance sensed by the detection circuit to selectively adjust an operation mode of the passenger conveyor.Type: GrantFiled: December 18, 2009Date of Patent: March 1, 2016Assignee: OTIS ELEVATOR COMPANYInventors: Nicholas C. Soldner, Arthur C. Hsu, William A. Veronesi, Bryan R. Siewert, Gero Gschwendtner, Abdullah Ercan, Alois Senger

Patent number: 9227818Abstract: A passenger conveyor includes an endless tread band having a plurality of treads. At least one endless drive chain is driven around a first and a second turn around section by a drive. The drivetrain includes a plurality of links that are associated with drive chain rollers. A plurality of the treads are connected with the drivetrain. At least one panel member is located on a lateral side of the treads. The panel member is moveable with respect to the treads and supported to remain stationary with respect to at least one of the drive chain links. Each of the treads is associated with at least one panel member.Type: GrantFiled: April 2, 2014Date of Patent: January 5, 2016Assignee: Otis Elevator CompanyInventors: Alexander Turek, Bernward Engelke, Alois Senger, Gero Gschwendtner, Detlev Lindemeier

Patent number: 9126810Abstract: Passenger conveyors with auxiliary brake systems are disclosed. The passenger conveyors include a truss that rotatably supports a loop sprocket at one end and a turnaround at an opposite end with an endless loop extending around the loop sprocket and the turnaround. The loop includes a plurality of rollers linked together. The truss is also coupled to a brake bar that has a braking surface, a downstream end and an upstream end. The brake bar is suspended above and biased towards the loop sprocket with the downstream end of the brake bar disposed a greater distance from the loop than the upstream end of the brake bar. A friction bar, which includes a first side that mateably engages the loop when placed onto the loop, is also provided that includes a top. The friction bar is suspended above the loop by an actuator, which is linked to a controller.Type: GrantFiled: January 30, 2012Date of Patent: September 8, 2015Assignee: Otis Elevator CompanyInventor: Gero Gschwendtner
