Abstract
A fastener device (1) which functions as a rock dowel and intended for use in rock climbing or for mooring boats, and the like, comprising a first element (2) and a second element (5) which are integrated with one another at a juncture (12). The first element (2) has the form of a wedge intended for co-action with a crack (3) in a rock surface or like surface, and the second element (5) forms an attachment for a line (8) or the like (7). The first element (2) is twisted in its longitudinal axis relative to a central plane (10) extending through the first element (2) from the juncture (12) at the second element (3).
Claims23
A fastener for securing a line to a crack in a rock surface, comprising:
- a longitudinally extending blade having a longitudinal axis, said blade being made from a deformable material;
- a portion of the longitudinally extending blade being helically twisted along its longitudinal axis;
- and
- means attached to one end of the longitudinally extending blade for attaching the line to the longitudinally extending blade, wherein the means includes an opening to receive the line;
- and wherein the blade and attaching means are strong enough to support the weight of a person on the line when the blade is inserted in the crack of the rock surface.
