Abstract:
1. A system for fastening a rail in place on a base, the system comprising: a guide plate which has a supported surface by which it is supported on the base in a fitted position, a contacting surface which is associated with a foot of the rail which is to be fastened in place, and a through-opening which runs from an upper side of the guide plate to the supported surface of the guide plate, a clamping member insertable through the through-opening in the guide plate and fastenable to the base, and a resilient member bent from a spring wire which has at least one portion acting in torsion at one end of which is formed a first supporting portion aligned at an angle to the portion acting in torsion and at the other end of which is formed a further supporting portion bent round from the portion acting in torsion, the length and angular position of the first supporting portion relative to the portion acting in torsion being of a size such that in the fitted position the first supporting portion is supported on an associated support surface on the guide plate and the resilient member being braced against the base by means of the clamping member in such a way that the portion acting in torsion exerts an elastic restorative force, the length of the portion acting in torsion being of a size such that, in the fitted position, that end of the portion acting in torsion which is associated with the further supporting portion projects beyond the contacting surface of the guide plate towards the rail, and the further supporting portion, starting with its one end from the assigned portion acting in torsion, being so bent back to the guide plate that it is likewise supported with its other end on the guide plate in the fitted position and forms a fixed point for the torsion on the portion acting in torsion, the further supporting portion forming a stop for a vertical movement of the rail.
