Plastic Dowel for Fastening of a Rail and Combination of such a Plastic Dowel and a Rail Screw

摘要

The present invention relates to a plastic dowel for the fastening of a rail on a solid substrate. The plastic dowel includes an opening, and interior, a shank section, and a holding section, which provides at least one circumferential projection around its circumference. The at least one projection protrudes in a radial direction whereby the upper flank of the projection of the holding section assigned to the dowel opening is aligned at an angle of 90°±3° in relation to a longitudinal axis of the plastic dowel.

主权项

1. Plastic dowel for fastening a rail on a solid substrate, with a dowel opening (3) formed at an end face of the plastic dowel (1) for insertion of a rail screw (2) into the plastic dowel (1), with a dowel interior space (8) enclosed by the plastic dowel (1), with a shank section (4) which connects to the dowel opening (3) as viewed in the longitudinal direction (LR) of the plastic dowel (1), and with a holding section (5) which connects to the shank section (4) as viewed in the longitudinal direction (LR) of the plastic dowel and which is provided on its outer side with at least one projection (11) running around its circumference and protruding in the radial direction (R) which, in its finished installed state, engages with the material of the solid substrate enclosing the plastic dowel (1) characterised in that the upper flank (12) of the projection (11) of the holding section (5), said upper flank (12) being assigned to the dowel opening (3), is orientated at an angle (β1) of 90°±3° in relation to the longitudinal axis (L) of the plastic dowel (1).
