  • the present invention is based on the object of developing an arrangement of the type mentioned in such a way that the rail can be held down using structurally simple measures, while at the same time being easy to maintain and service. It should be possible to tension the spring safely using simple measures.
  • the first abutment is a section of the plate element or extends from it, which runs in the area remote from the rail foot
  • the second abutment is an eccentric element which preferably extends in the longitudinal direction of the rail and which is in a between the rail foot and the first abutment and extending from the base is rotatably arranged

  • a contact area of the first abutment has a cylindrical section geometry and that the spring element rests with a geometrically adapted end area on the first abutment and surrounds it in areas. This ensures, among other things, that at least in the tensioned state of the spring element it cannot be displaced in its longitudinal direction.
  • the eccentric element is a rod-shaped element which has an eccentric geometry in cross section in the contact area with the spring element such that in a first position of the eccentric element the spring element can be positioned without tension and in a second position of the eccentric element the spring element is tensioned in such a way that both the rail foot and the plate element and the spring element are held down.
  • the eccentric element In the contact area with the spring element, the eccentric element should have a circular segment or circular segment-shaped geometry in section, whereby the distance of the contact area from the base is changed depending on the rotational position of the eccentric element and thus the spring element can be tensioned or relaxed.

  • the eccentric element should have an actuating head, such as a polygonal head, in particular a square head, at least in one of its ends in order to enable problem-free rotation of the eccentric element and thus tensioning and relaxing of the spring element.
  • an actuating head such as a polygonal head, in particular a square head, at least in one of its ends in order to enable problem-free rotation of the eccentric element and thus tensioning and relaxing of the spring element.
  • No special tools are required. Rather, an open-end wrench can be used, for example.
  • the spring element that should be mentioned in particular is a leaf spring, the largest cross section of which runs like an eccentric bolt in the contact area with the eccentric element.
  • the top side i.e. the surface facing the eccentric element, should have a concave shape and a convex shape on the underside, with the radius of curvature of the convex shape being smaller than that of the concave shape in the contact area.

  • a tongue rail 42 which is adjusted on the surface of the sliding chair 16, is adjusted to the stock rail 14.
  • the sliding chair 16 is a component manufactured independently of the base 18 and can be manufactured, for example, by forging or casting or milling. If the sliding chair 16 is a cast component, cast iron with spheroidal graphite or cast steel should be used.
  • the sliding chair 16 has a recess 44 running in its longitudinal direction and in particular in the central region, in which the spring element 10 extends.
  • the recess 44 is covered to form a closed sliding surface for the tongue rail 42.
  • the recess 44 is delimited by side walls 48, 50, between which the leaf spring 10 runs.
  • the side walls 48, 50 Approximately in the middle area between the back and front of the sliding chair 16, the side walls 48, 50 have recesses 52, 54, which pass through the sliding chair 16 over its entire height in order to provide a space for a recording or storage 56, which is of the document 18 starts.

  • the recesses 52, 54 preferably have a rectangular shape in plan view.
  • the side legs 58, 60 have openings or bores 64, 66 aligned with one another, through which the eccentric element 12, referred to as a shaft or rod, passes through in order to be able to rotate it.
  • the eccentric element 12 has an actuating head 68, such as a square head, in one end region in order to rotate the eccentric shaft 12, which is geometrically designed in the contact region 70 with the spring element in such a way that the desired eccentric effect is given, that is, it is dependent depending on the position of the shaft 12, the spring element 10 is either tensioned ( Fig. 4 ) or relaxed ( Fig. 3 ).
  • the eccentric region 70 in particular has the geometry in the section of a circle segment. Other geometries that allow the spring 10 to be bent to tension it can also be used.
  • the through openings 64, 66 of the bearing block 56 are aligned with openings 72, 74 in the side walls 48, 50 of the sliding chair 16, so that the eccentric element 12 passes through all of the holes and extends from the outside of the Leg 48 can be rotated using a tool such as an open-end wrench.
  • the eccentric element 12 Since the eccentric element 12 passes through the side walls 48, 50, the eccentric element 12 simultaneously forms a tilt protection for the stock rail 14 and the sliding chair 16. Another advantage of attaching the eccentric element in the middle area is that if the spring element breaks, the plate element continues to prevent tipping , lifting and moving is held securely in position. That's it too ensures that the rail to be fastened is held in the desired position. Special precautions such as projections or notched nails extending from a base plate that get caught on the plate element can be omitted, which enables a simpler design.
  • recesses 49, 51 extending from the backs of the side walls 48, 50 can also be seen, into which projections 53, 55 extending from the base 18 engage (see Fig. 2 ) to provide protection against displacement.
