An anchor comprising flukes, a shank hinged to the flukes and transversely extending stabilizing arms, wherein the hinge point of the shank substantially coincides with the geometric centre of the fluke surface area and head faces are provided on either side of the hinge point, which head faces are formed by head plates spaced from the geometric centre of the fluke surface area, which head plates converge towards the front of the flukes both in vertical and in horizontal direction, delimit the s...

An anchor provided with a shank which is pivotally connected to a hollow fluke construction near the center of gravity of the fluke construction, characterized in that the fluke construction is formed as a peripherally closed, substantially delta-shaped blade having a forwardly converging hydrofoil section with a forwardly and downwardly bending configuration terminating in a sharp front edge, and a truncated rear portion, and having a central opening for receiving the shank.

An anchor, especially for use with yachts, having a pair of anchor arms on one end of its shank and a stock member having a pair of arms projecting to opposite sides of the shank, in which the stock member is movable on the shank between a working position located in the region of the other end of the shank with its arms extending transverse to the anchor arms and a storing position located closely adjacent to and with its arms located substantially in one plane with the anchor arms.

The present invention relates to an anchor for floating devices and includes a body provided with a shackle linked to an anchor chain, with one set member for engaging the bed of a body of water being jointedly mounted on said body. The body includes a first portion having two longitudinal ends and a second portion extending between the ends of the first portion and being spaced away so as to surround a void space therebetween. The shackle is slidingly mounted along the second portion and the se...

Anchor for anchoring dredgers, off-shore drilling platforms and other special purpose vessels, comprising a shank, two flukes hinged to the shank having together a Delta shape, trim plates or head faces provided on both sides of the flukes, the width of the trim plates being less than the total width of the flukes, characterized in that the outer ends of both trim plates are connected to the outer rims of the flukes by stabilizing plates which enclose an acute angle both with the direction of th...

An anchor is provided with a base, shaft, and fastening element in the shaft for securing a line to the anchor. The base includes a plurality of outwardly facing, shovel-like indentations defined by a plurality of generally smooth, concave scooping surfaces on the top of the base. Between each shovel-like indentation is a ridge extending radially outward from the center of the base and terminating at one of the corners of base. The shovel-like indentations enable the anchor, when resting on one ...

A construction anchor for mounting an object on a structure of masonry, concrete, wood, metal or the like includes an anchoring portion and a cap. The anchor is adapted to be inserted, anchoring portion first into a pre-drilled adhesive-filled hole. The anchoring portion has a threaded bore, which includes an unthreaded close-fit-counterbore portion outward of a threaded portion. The cap prevents dust, dirt and adhesive from entering the threaded bore, and has an upper surface with a removable c...

This invention describes an anchor for use with small boats which comprises a fluke in the shape of a rectangular sheet or plate of metal formed into a cylindrical form. A short strip is welded to the plate in a radial direction. A shank is mounted on this strip by means of a bolt which permits rotation about an axis parallel to the axis of the cylinder. Detent means are provided so that when the shank is in a radial direction with respect to the fluke, it is locked in that position. However, by...

An anchor made up of at least two frame parts pivotally interconnected, at least one fluke hingedly connected to each frame part, one frame part being pivotable for at least 180.degree. from an unfolded position to a folded position into a second frame portion, the first frame part and its fluke being received between the flukes of the second portion.

An anchor having a shank and a fluke, which is formed by a flat plate and the shank is fixedly secured to the plate at an angle .alpha., which is smaller than 45.degree., and preferably 32.degree..
