摘要:
The invention provides a system for screwless rail fastening and a corresponding fastening point on an underlying surface, which are easy to assemble and ensure optimal secure fastening with maximum load capacity and under hard usage conditions. For this purpose, such a system comprises a spring element (4), which is bent from a spring wire, and a support shoulder (2). In succession from one end of the spring element, the spring element (4) comprises a support segment (4a), a curve segment (4b), a hold-down segment (4c), which is oriented opposite to the support segment (4a), a curve segment (4d), which is curved in the direction of the support segment (4a), and a locking segment (4e), which is oriented transversely with respect to the support segment (4a). When the spring element (4) is not mounted, there is a distance (a) between the hold-down segment (4c) and the locking segment (4e) when viewed from the side. At the same time, the support shoulder (2) comprises a fastening segment for holding the support shoulder (2) on the underlying surface (U), a carrier segment (2a) supported by the fastening segment, a support hole (2f) formed on the carrier segment (2a) for pivotably supporting the support segment (4a) about a pivot axis, and a locking head (2b), which is supported by the carrier segment (2a) and on which an abutment (2i) for the locking segment (4e) is formed in such a way that, when the system (1) is fully assembled, the locking segment (4e) is held in a position relative to the support segment (4a) of the spring element (4) in which the spring element (4) is resiliently loaded between the support hole (2f) and the abutment (2i) of the support shoulder (2) and the hold-down segment (4c) acts resiliently against the surface of the rail foot (F) that is associated with the hold-down segment.

The invention relates to a system for fastening a rail (S) to an underlying surface, comprising an underlay plate (4), which has a support surface (20) for the rail (S) to be fastened, and at least one guide plate (5, 6) which is seated on the underlay plate (4) and has a through-opening (38) intended for a clamping element (8, 9) and leading from the free upper side (37) of said guide plate to its lower side (44) resting on the underlay plate (4), which clamping element, with the system completely mounted, is guided through the through-opening (38) and fixedly connected to the underlying surface, wherein a latching connection between the underlay plate (4) and the guide plate (5, 6) is formed in the region of the through-opening (38) of the guide plate (5, 6) by at least one latching arm (25, 26) which engages through the through-opening (38) of the guide plate (5, 6) and has at its free end a latching projection (27, 28) which positively interacts with a stop formed on the guide plate (5, 6). In order to simplify the mounting of the system on the respective underlying surface, a cutout (42, 43) is formed in the circumferential surface (40) delimiting the through-opening (38) of the guide plate (5, 6), in which cutout the respectively assigned latching arm (25, 26) is seated.

The plate (3) has an insulator element (19) which is placed in a foot (F) of the rail to be fastened and a spring element (13) acts on the foot of the rail through the insulator element. The insulator element is mounted on the guide plate, and is freely pivoted about the guide plate from a pre-mounting position to a mounting position. An independent claim is included for system for fastening rail to base.

System (1) zum Befestigen einer Schiene (S) auf einem Untergrund (U) und eine für ein solches System (1) bestimmte Unterlegplatte (2,3). Das System (1) umfasst eine Führungsplatte (7,8) zum seitlichen Führen der zu befestigenden Schiene S, ein gegen den Untergrund U mittels eines Spannelements (15,16) verspannbares, auf der Führungsplatte (7,8) sitzendes und bei fertig montiertem System (1) mit einem freien Federarm (48,49) eine Niederhaltekraft auf einen Schienenfuß (F) der Schiene (S) ausübendes Federelement (9,10) sowie eine Unterlegplatte (2,3), die zum Ausgleich von Höhenunterschieden zwischen der Führungsplatte (7,8) und dem jeweiligen Untergrund (U) angeordnet ist. Die Unterlegplatte (2,3) ist in zwei Teile (24,25) entlang einer Stoßlinie (32) zu teilen, die von der einen der quer zur zu befestigenden Schiene (S) ausgerichteten Längsseiten (26,27) der Unterlegplatte (2,3) ausgehend mit Abstand (a1,a2) zu deren einen Schmalseite (28,29) zu der Durchgangsöffnung (30,31) und von dort die Durchgangsöffnung (30,31) schneidend in Richtung der Schmalseite (28,29) der Unterlegplatte (U) geführt ist.

Eine elastische Spannklemme aus Federstahl zur Schienenbefestigung umfasst eine Mittelschleife (44) mit zwei durch ein bogenförmiges Mitteilteil (48) verbundenen Innenschenkeln (46) sowie Schlaufen (42), die sich an die Innenschenkel (46) der Mittelschleife (44) anschließen und zu den freien Enden (50) der Spannklemme (40) verlaufen. Die Schlaufen (42) sind so geformt, dass sie im unbelasteten Zustand jeweils eine maximale Höhe (H) von mindestens 20mm über der oberen Ebene (E 2 ) der Mittelschleife (44) im Bereich der zwei Innenschenkel (46) besitzen.
