In the connection portion, a splice junction between the metal stretch inhibitors and a joint where the base members are connected together at both end portions with an auxiliary backing does not overlap in a direction of thickness of the moving handrail. Further, the metal stretch inhibitors that are spliced are enclosed with a thermoplastic elastomer.Type: GrantFiled: August 20, 2003Date of Patent: July 13, 2004Assignees: Mitsubishi Denki Kabushiki Kaisha, Kabushikikaisha TokanInventors: Tsuyoshi Onodera, Muneaki Mukuda, Kohsuke Haraga, Ryuji Otsuka, Yuji Kawamura

Publication number: 20030136635Abstract: An escalator handrail load monitoring and detection apparatus monitors and detects variations to a load applied to the handrail during operation. A distortable element is mounted to a handrail guide upon which the handrail rides and responds through distortions to downward-applied forces to the handrail. An electrical switch is activated by the distortion, allowing an output signal to be generated indicating that a particular minimum downward force has been applied to the handrail. The minimum force may be chosen to be above the range of forces normally applied to the handrail during normal passenger use, and thus be responsive to unsafe or improper operating conditions, such as when a passenger sits on the handrail or places packages thereon.Type: ApplicationFiled: January 4, 2002Publication date: July 24, 2003Inventor: Richard Lauch

Patent number: 6533098Abstract: An escalator construction has a framework, steps and a balustrade at both sides of the steps. The balustrade is fastened to balustrade posts. Clamps for profile tubes are provided at the framework and optionally also at the balustrade posts, U-profile members for receiving the profile tubes can be provided at the lower part of the framework Partition walls are fastened to both the inner and outer sides of the profile tubes. In order to cover the fasteners, the outer partition walls are fastened at least at its lower portion from an internal face, while the fasteners at the lower portion of the inner walls are covered by the balustrade. The fasteners for the upper portions of the partition walls may be covered by a cover profile member.Type: GrantFiled: March 14, 2001Date of Patent: March 18, 2003Assignee: Inventio AGInventor: Gerald Winkler

Patent number: 6367608Abstract: The present invention relates to a device forming a moving handrail for an accelerated moving walkway. The device including a rail which carries backing carriages and which converges towards the rail carrying the carriages that support the handrail handholds in a zone situated between the divergence zone and the turn-around zone; in at least the divergence zone, said rail follows a cam outline having an oscillatory profile in which the length of each wave is equal to the distance between a first one and a third one of the consecutive backing carriages, each placed at a respective end of the wave that they flank.Type: GrantFiled: April 20, 2000Date of Patent: April 9, 2002Assignee: Constructions Industrielles de la Mediterranee—CNIMInventor: Jean-Claude Franceschi

Publication number: 20010023810Abstract: An escalator or moving walkway is provided with a guide device to maintain the positions of the steps or plates with respect to the escalator sides. A respective guide device is provided at each step side which guides the steps laterally in the horizontal direction and insures a minimum spacing of the step from the base plate of the escalator balustrade base. In the forward run portion of the step belt the guide device engages the base plate, while in the return run portions of the step belt, the guide device engages the side surface of a second guide for chain rollers.Type: ApplicationFiled: March 20, 2001Publication date: September 27, 2001Inventors: Gerhard Lunardi, Reinhard Pallinger

Patent number: 6223879Abstract: An escalator or moving walkway for transporting people along a moving path includes a mounting assembly for attaching a roof structure to enclose the moving path and protect the people from rain an other undesirable environmental factors. The escalator is supported by a truss structure. A main bracket is secured to the truss structure outboard of the moving path and a handrail extends along the length of the moving path. Outer decking is secured to the main bracket for partially enclosing the truss structure. At least one roof bracket is mounted to the outer decking for gripping engagement with the main bracket and a roof support member is secured to the roof bracket for supporting the roof structure to enclose the moving path of the escalator or moving walkway. Preferably the main bracket includes grooves or channels for receiving outwardly extending tabs on the roof bracket to prevent vertical separation between the roof and main brackets.Type: GrantFiled: July 31, 2000Date of Patent: May 1, 2001Assignee: Otis Elevator CompanyInventor: Karl-Friedrich Schöps
