  • Patent number: 11913215
    Abstract: 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.

  • Patent number: 10150650
    Abstract: 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.

  • Patent number: 9834416
    Abstract: 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.

  • Patent number: 9481551
    Abstract: 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).

  • Patent number: 8555479
    Abstract: 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.

  • Patent number: 7426989
    Abstract: An escalator or moving walk has a truss that is supported in the area of its extreme ends. In the area between its two extreme ends, the truss has at least one tension element which, at a first end, is connected mechanically to the truss, and at a second end is connected to a fastening point. The tension element is constructed and tensioned such that it exerts a tensile force on the truss that acts at least partly in the direction of the earth's gravitational force.

  • Patent number: 6814215
    Abstract: 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.
