Patent number: 11913215Abstract: A framework section having a connection region which is formed on the end face of at least one of its two ends. The connection region can be connected to the connection region of a further framework section. The framework section can include two upper chord sections and two lower chord sections, which extend parallel to one another in the longitudinal direction of the framework section and are connected to one another by connecting struts such that they define a cuboid space. The upper chord sections and the lower chord sections can have a tubular cross section, wherein the upper chord sections and the lower chord sections can also be configured to transition from the tubular cross section into an I-shaped cross section in the connection region.Type: GrantFiled: February 18, 2020Date of Patent: February 27, 2024Assignee: INVENTIO AGInventors: David Krampl, Michael Matheisl, Richard Schütz, Robert Schulz, Thomas Koukal

Patent number: 10150650Abstract: This application relates to a method for installing a support structure for a passenger transport system in a construction. The support structure comprises a framework made of load-bearing framework components connected to each other. The method includes placing a plurality of individual framework components, having connection openings designed therein, at an installation position within the construction; and assembling the framework on or near the installation position within the construction by connecting the framework components to each other by way of load-bearing connector components, in that a respective connector component is arranged to reach through adjacently arranged connection openings of at least two adjacent framework components and is then deformed in respect of the outside geometry thereof, such that they completely fill out the connection openings they reach through, without play.Type: GrantFiled: September 22, 2016Date of Patent: December 11, 2018Assignee: INVENTIO AGInventors: Thomas Illedits, Christoph Makovec, David Krampl, Robert Schulz, Michael Matheisl, Uwe Hauer

Patent number: 9834416Abstract: A support system supports the two ends of a passenger-transportation device in a built structure. The support system 6 has a swiveling support-point at a first end with a vertical swivel-axis. The second end contains a floating support-point for absorbing horizontal movements perpendicular to the swivel-axis. The floating support-point has at least one rolling element by means of which a sliding friction caused by the occurrence of horizontal movements in the floating support-point can be transformed into combined sliding-and-rolling friction or rolling friction.Type: GrantFiled: November 14, 2014Date of Patent: December 5, 2017Assignee: INVENTIO AGInventors: David Krampl, Gerald Winkler, Günter Horvath, Günther Niedermayer, Michael Matheisl

Patent number: 9481551Abstract: The invention relates to a transparent balustrade (12) of an escalator (1) or of a moving walk, comprising a balustrade skirt (13), at least one glass panel (33), and a handrail guide (15) with a handrail (14). The at-least one glass panel (33) has an upper edge (9) and a lower end (6) and, at its lower end (6), is gripped in a mounting (18) in the balustrade skirt (13) in locationally fixed manner. The transparent balustrade (12) contains at least one support (20), which is tightly joined to the balustrade skirt (13). The glass panel (33) is deformable perpendicular to its planar extent and therefore in lateral direction. Through its elastic deformability, to absorb lateral forces (F) the glass panel (33) displays lateral displaceability within a permissible deformation play (s), lateral displaceability within the permissible deformation play (s) being limited by the support (20).Type: GrantFiled: December 3, 2013Date of Patent: November 1, 2016Assignee: INVENTIO AGInventors: David Krampl, Günther Niedermayer, Michael Matheisl, Gerhard Kleewein

Patent number: 8555479Abstract: A method of producing a load-bearing steel construction connection, wherein a clinch connection (13) connecting a first metal workpiece (6.1, 6.2) with a second metal workpiece (6.3, 6.4) is formed by local deformation by means of a die tool (20) and a counter-tool (30). In that case initially the first metal workpiece (6.1, 6.2) and the second metal workpiece (6.3, 6.4) are placed one on the other on a processing surface of the counter-tool and aligned. The die of the die tool is then advanced and sunk into the two metal workpieces (6.1, 6.2; 6.3, 6.4) placed one on the other until the clinch connection (13) has been formed by plastic deformation. The first metal workpiece (6.1, 6.2) has a first workpiece thickness (t1) and the second metal workpiece (6.3, 6.4) has a second workpiece thickness (t2), which together give a total workpiece thickness (tt) which is thicker than 8 millimeters.Type: GrantFiled: August 12, 2009Date of Patent: October 15, 2013Assignee: Inventio AGInventors: Andreas Trojer, David Krampl, Michael Matheisl, Richard Schütz, Thomas Novacek, Markus Israel, Reinhard Mauermann

Patent number: 6814215Abstract: A support construction for an escalator or moving walkway comprises at least one framework element integrally constructed as a flat, non-profiled, cut plate. Multiple framework elements can be assembled into a unitary support construction. By virtue of the simple structure of the support construction. Wherein little welding work is needed, production time for the support construction is substantially reduced over conventional constructions.Type: GrantFiled: December 18, 2002Date of Patent: November 9, 2004Assignee: Inventio AGInventor: David Krampl
