Patent ID: 7992798

Claim:
System for fastening a rail on a substrate, with a base plate, molded into which is a central portion, a width of the base plate is adapted to a width of a rail foot of the rail to be fastened, with at least one fastening element for connecting the base plate to the substrate and with at least one tensioning element provided for holding down the rail on the base plate, wherein an opening is molded into the base plate, which opening emanates from an upper side thereof associated with the rail, leads to an underside thereof associated with the substrate and has a non-circular cross-sectional shape, the at least one tensioning element is intended to be slid into the opening from the underside of the base plate and includes a shank, a head which is formed integrally with the shank and a diameter of the head is larger than a diameter of the shank, and a transition portion which is formed between the head and the shank and a cross-sectional shape and dimensions of the transition portion are adapted to a shape and dimensions of the opening in the base plate in such a way that the transition portion is positioned, when placed into the opening, in the opening so as to be prevented from rotating by a form fit, a spring element is provided which can be braced against the base plate with an aid of the at least one tensioning element and has at least one spring arm which, when the spring element is braced against the base plate, exerts a resilient holding-down force onto a rail foot, a guide plate is provided which can be laid on the base plate and has a recess, through which the shank of the at least one tensioning element can be inserted, and at a free upper side, which is remote from an underside associated with the base pate, a shaped element for guiding at least a portion of the spring element supported against the base plate; and two projections, which are arranged set apart from each other and are intended laterally to surround one of the at least one fastening element intended for connecting the base plate to the substrate, are configured at a portion of the guide plate.
