Patent number: 8240452Abstract: A tread element for a conveyor such as an escalator or moving sidewalk has a tread plate and at least one border strip. First and second abutment arrangement for the strip are provided, and include a first groove element and a tongue element on mating portions of the tread plate and strip. Interacting stop surfaces of the abutment arrangements on the plate and strip prevent relative movement in the direction of mounting, while one of the abutment arrangements provides a locking arrangement between the tread element and strip.Type: GrantFiled: July 14, 2008Date of Patent: August 14, 2012Assignee: Inventio AGInventors: August Fischer, Gerhard Lunardi, Michael Matheisl, Wolfgang Neszmerak

Publication number: 20100320058Abstract: The invention relates to a tread element (20) for a conveyor such as an escalator or moving sidewalk. The tread element (20) comprises a tread plate (22) having a tread surface (22.1) and a strip (30), preferably of a plurality of strip elements (40, 50) on the tread surface (22.1). A fixing arrangement has a first groove element and a second tongue element, one element being attached to the tread plate (22) and the other element to the strip elements. The two elements cooperate to prevent movements of the strip elements (40, 50) relative to the tread element (20) from the tread surface (22.1) away. Interacting stop surfaces on the strip elements and on the tread plate are designed to prevent movements of the strip elements in the direction of mounting, opposite to the direction of mounting and perpendicular to the direction of mounting and in parallel to the tread surface (22.1).Type: ApplicationFiled: July 14, 2008Publication date: December 23, 2010Applicant: INVENTIO AGInventors: August Fischer, Gerhard Lunardi, Michael Matheisl, Wolfgang Neszmerak

Patent number: 6991084Abstract: In an escalator, a handrail is supported medially and reversed by means of a reversing sheave, which rotates about an axle which has approximately the width of a balustrade. The axle is held by at least one supporting cheek. A handrail-drive, which is integrated in the balustrade base, drives the reversing sheave by means of a drive-wheel, the handrail, which is guided over a diverter roller, being carried along by friction from the reversing sheave.Type: GrantFiled: April 15, 2004Date of Patent: January 31, 2006Assignee: Inventio AGInventor: Gerhard Lunardi

Patent number: 6974018Abstract: An escalator has a step-band with steps for the transport of persons. The step-band is bounded on its sides by a balustrade held by a balustrade base. A handrail-drive drives the handrails, and has friction-wheels driving the handrails on the outside of the handrails. Rollers press upon the insides of the handrails, pressing the handrail against the friction-wheel. At least one further friction-wheel arranged on a step chain-wheel drives the friction-wheel through frictional or mechanical engagement.Type: GrantFiled: April 1, 2004Date of Patent: December 13, 2005Assignee: Inventio AGInventors: Gerhard Lunardi, Michael Matheisl

Patent number: 6471034Abstract: 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: GrantFiled: March 20, 2001Date of Patent: October 29, 2002Assignee: Inventio AGInventors: Gerhard Lunardi, Reinhard Pallinger

Patent number: 6155401Abstract: A drive for an escalator is installed on one or both sides of the escalator at the lower and/or upper end and comprises one to several identically constructed drive units, which are arranged and distributed about the circumference of a main drive wheel. The drive units can be flange-mounted in either a longitudinal or transverse direction to the direction of travel of the escalator on a common main gear housing which can be identical for the support of one or more drive units. The operation of the motors of the drive units are controlled by way of a common frequency-setting device. A control and regulating unit processes input data into control and regulating data for the frequency-setting device, a relay control and optical signals and illumination for the escalator. The individual drive units are switched in or out according to the actual power requirements of the escalator during operation.Type: GrantFiled: January 28, 1999Date of Patent: December 5, 2000Assignee: Inventio AGInventors: Gerhard Lunardi, Robert Ulrich

Patent number: 6105748Abstract: An escalator or travelling walkway, which connects a first story with a second story, has plates forming a walkway for conveying persons and objects. The travelling walkway is laterally bounded by balustrades. Each balustrade carries a moving handrail which advances at the speed of the plates. A balustrade pedestal supports the balustrades. Serving as a support for the plates are one or more support bodies having a beam lower edge, at which underneath bracing is arranged. The bracing may be in the form of tie rods, connected to ends of the support bodies and to the middle of the support bodies by a central support.Type: GrantFiled: March 16, 1998Date of Patent: August 22, 2000Assignee: Inventio AGInventors: Reinhard Pallinger, Gerhard Lunardi

Patent number: 4638901Abstract: In escalators or moving stairways there exists, between the moving step and the fixedly positioned skirt guard, a latent risk of entrapment or catching of the shoe of the passenger, especially when wearing light footwear. The inventive warning devices are arranged at the side uprights or plates of the step of the escalator and induce the user or passenger, by means of a physically and, possibly additionally, by means of an acoustically perceptible signal, to leave the stepped-on danger zone. Each of the warning devices comprising, for example, two swivelingly or pivotably mounted segments is held in a projecting readiness position, through the force of a spring, in relation to the tread surface and the front surface of the step.Type: GrantFiled: August 8, 1985Date of Patent: January 27, 1987Assignee: Inventio AGInventor: Gerhard Lunardi

Patent number: 4484674Abstract: The guiding apparatus comprises substantially rectangular rail holders and L-shaped rail holders. Main and follower travel rails or tracks are supported by such rail holders and there are provided side plates at which there are mounted the rail holders, the side plates being supported upon a carrier frame. These rail holders are provided at their attachment or fastening side with at least two respective centering protuberances or nubs or the like which engage into corresponding centering openings provided in the side plates to which the rail holders are fastened. The rail holders possess, at their rail contact side, a dovetail clamping device which, in cooperation with a dovetail profile or section extending along the underside of the travel rail or track, to reliably and easily releasably holds the travel rails and the rail holders by virtue of a clamping action which is exerted at all sides of the dovetail profile.Type: GrantFiled: November 30, 1981Date of Patent: November 27, 1984Assignee: Inventio AGInventors: Gerhard Lunardi, Gerhard Wipp
