Patent number: 7168526Abstract: This patent relates to a machine for transporting people and cargo with three-dimensional and infinite movement along properly positioned rails. The main application is for transporting people between two points with different coordinates, for example between one floor of one building and another floor of another building, kilometres away. It is composed essentially of: a set of wheels (1 and 2) that roll on the rails (8 and 9); a cabinet (7) where the people and cargo are transported; a chassis that connects the wheels to a “T” beam (10); this “T” beam (10) connects the chassis to the cabinet (7); electrical engines that move the wheels. The set of parts allows the cabinet to have a non-straight, three-dimensional and infinite movement, the cabinet always being in the vertical position.Type: GrantFiled: November 17, 2004Date of Patent: January 30, 2007Inventor: Vasco Alexandre De Sousa Marreiros Alves

Patent number: 7156210Abstract: A control system for a motorized freight elevator landing door in which all of the doors in a single line of a hoistway are controlled with one set of proximity sensors carried on the elevator car. The sensors signal a controller that operates electric motors for opening and closing the landing door where the car has stopped. The door operating motors are two speed units and the sensors and controller are arranged to operate the motors at high speed during most of the travel in opening or closing movement and at reduced speed at the end of movement. The controller applies power to the motor for a short period after the door is fully closed or open to stall the motors and thereby dampen any rebound motion.Type: GrantFiled: February 24, 2003Date of Patent: January 2, 2007Assignee: The Peelle Company Ltd.Inventors: Steven P. Reynolds, Richard W. Lajeunesse, Zygmunt Dziwak, David E. Kairis

Patent number: 7147087Abstract: An elevator is provided to prevent a tail cord from being projected out of a tail-cord duct under the influence of air current flowing in the tail-cord duct. The tail-cord duct is formed along an elevating space in which a passenger car moves up and down. The tail-cord duct is provided, along the elevating space, with an opening that opens it. An arm part fixed to the passenger car is introduced into the tail-cord duct. In the tail-cord duct, a tail cord is suspended from the arm part. In plan view of the tail-cord duct, a portion of the arm part for suspending the tail cord is shifted from the opening in a duct-width direction of the duct.Type: GrantFiled: December 4, 2003Date of Patent: December 12, 2006Assignee: Toshiba Elevator Kabushiki KaishaInventor: Kazuhiro Tanaka

Patent number: 7017714Abstract: There is provided a double-deck elevator which does not cause any impacts or vibrations on each cage when adjusting the spacing in the vertical direction between upper and lower cages. Loads on an upper support beam from right and left support arms for hoisting and supporting the upper cage are measured by right and left upper measuring units. Similarly, loads on a lower support beam from right and left support arms for hoisting and supporting the lower cage are measured by right and left lower measuring units. Because the magnitude of the loads on the right and left screw shafts can be obtained correctly, any impacts or vibrations caused on each cage can be prevented when adjusting the spacing in the vertical direction by correctly controlling the drive torque output from right and left drive motors.Type: GrantFiled: March 18, 2003Date of Patent: March 28, 2006Assignee: Toshiba Elevator Kabushiki KaishaInventors: Yoshiaki Fujita, Naoki Kondo
