  • Patent number: 8371228
    Abstract: The invention relates to a flexible steel support (31) for a switch arrangement in maglev railways. The flexible support (31) contains a hollow profile (32) that extends in a longitudinal direction (x) and a hollow profile that can be bent in a transverse direction (y) and that is provided with lateral sheet metal struts (35) and a top flange (33). The support is also provided with a plurality of cantilever arms (38) that extend in the transverse direction (y), are interspaced in the longitudinal direction (x) and are connected to the sheet metal struts (35) and a plurality of metal cover sheets (42) that are arranged one behind the other in the longitudinal direction (x) and are supported on the cantilever arms (38), the connections between the sheet metal struts (35), cantilever arms (38) and metal cover sheets (42) consisting of welded joints.

  • Patent number: 7966942
    Abstract: The invention relates to a bending mount (24) for a switch arrangement for magnetically levitated railways. The bending mount comprises at least a box-shaped support element (25) that extends in the longitudinal direction (x) and on which are fixed successively arranged supporting metal sheets (27) that extend on both sides of the support element and serve to assemble the pieces of equipment (10, 12). According to the invention, the supporting metal sheets (27) are configured as single-piece components which extend over the width of the bending mount and are interlinked in the longitudinal direction to form a chain. Said chain essentially does not influence the flexural rigidity of the support element (25) in the desired direction (y) of a switching arrangement but exhibits a high rigidity against torsion about the longitudinal axis (x) and against vibrations in the vertical direction (z).

  • Patent number: 7588215
    Abstract: A mount for a magnetic levitation railway has functional elements (9, 10, 11) for guidance of a vehicle for the magnetic levitation railway, on both sides along its longitudinal extent. The mount is in the form of a bending mount (2) of a switch arrangement and can be moved elastically from a first position of a first driving direction of the vehicle to at least one second position of a further driving direction of the vehicle. The bending mount (2) is produced essentially from concrete.

  • Patent number: 6499588
    Abstract: A conveying system for conveying items along a conveying line (1, 2) includes a guide device (3) extending along the conveying line and at least one conveying element (5) movable along the conveying line and guided by the guide device (3). The guide device (3) and conveying element (5) are designed for conveying the items substantially independent of gravity. For selectable connection of the conveying line to a plurality of connecting points (A.1-A.3) the conveying system includes, connected to a invariable conveying line region (1) with a fixedly mounted guide device, a variable conveying line region (2) in which the guide device (3) is reversibly bendable and twistable. For bending and/or twisting the guide device and for supporting the guide device in a bent and/or twisted position necessary for a specific connection, a drivable connector (8) is provided. The variable conveying line region (2) may be an end region of the conveying line.

  • Patent number: 6332405
    Abstract: A diverter for a suspended conveying apparatus in which conveyable-article carriers provided with running rollers are guided on running rails. A diverter tongue is connected to a running-rail section via an articulated arrangement so as to be pivotable between two diverter positions. The articulated arrangement includes a bridging element that connects the running profile of the running-rail section to the running profile of the diverter tongue and is mounted to be pivoted about an axis on the running-rail section as well as about an axis on the diverter tongue. In a transition region between the running-rail section and the bridging element, in each case one running-roller guide surface of the running-roller section and one running-roller guide surface of the bridging element run one beside the other in the conveying direction to respectively support a running roller of a conveyable-article carrier.

  • Patent number: 5199674
    Abstract: A switch for connecting a main track girder selectively to any of a plurality of branch track girders includes a plurality of movable girders with articulations between adjacent movable track girders and between the main track girder and one of the movable track girders adjacent thereto, forming a stepped curve. The track girders have main rails fixedly secured thereon, respectively, for guiding a vehicle and for forming the stepped curve according to the arrangement of the main track girder and the movable track girders. A short intermedial rail is provided between the adjacent main rails. The short intermedial rails have both ends connected to the main rails on adjacent main track girders and adjacent movable track girders with relatively variable angles.

  • Patent number: 4870906
    Abstract: The invention relates to a dual track system for rail vehicles and magnetic vehicles. To enable this track system to be used in common by conventional wheel-and-track vehicles and magnetic vehicles, switches are needed by which both types of vehicle can be switched from a track on which only the one type of vehicle can run to a track which can be used by both types of vehicle. Furthermore, the switch must be suited for providing branches in a track on which both types of vehicles can operate. For the solution of this problem the invention provides a switch system which is essentially characterized by a flexible beam (6a) on which a likewise flexible track section (21) is mounted, which is intended for common use by rail vehicles and magnetic vehicles, and by an apparatus (31) for opening or closing a gap (30) between the beam and each such track (1a) to be traversed by the rail vehicles which permits the flexing of the beam.
