Anchor for heavy loads

Abstract

An anchor has a fluke (3) having an underside (2) lying in one flat geometrical plane and comprising two fluke parts (5, 6) which each have a forwardly pointed tip (7, 8) on either side of the central plane (9) of symmetry which is perpendicular to the geometrical plane (2) of the underside. These two fluke parts (5, 6) form an integral unit at the central plane (9) and have their front edges (10, 11, 12, 13) in that geometrical plane (2) tapering towards the respective tips (7, 8) and from each tip (7, 8) extend rearwardly with a cross section in each plane perpendicular to the underside plane (2) and perpendicular to the plane (9) of symmetry. That unit is substantially triangular up to and beyond the point where the inner front edges (11, 12) of the fluke parts (5, 6) meet, which triangular cross sections (10, 11, 12, 13) have their apex (22, 23) according to a straight ridge line which from each tip (7, 8) extends rearwardly at a sharp angle (.alpha.) with the underside plane (2). The triangular cross sections merge into each other at the central plane of symmetry. The fluke (3) has adjustably connected therewith a shank (14) which by a transfer pin (15) and a spaced-apart adjustable point of connection (16) can be placed at a predetermined sharp angle with respect to the plane (2) of the underside. The entire fluke (3) has a box-like structure in that the plane (2) at the underside is formed by a flat plate (2).
