An anchor makes it possible to easily fasten an object to a brittle wall. The anchor has a plate member formed with a hole for receiving a screw, a pair of legs extending from the bottom of the plate member at both sides of the screw hole, and a slide grip member slidably mounted on the legs. With a wall sandwiched between the plate member and the slide grip member, both members are prevented from turning. Thus, it is possible to fasten an object to the wall simply by threading a screw into the ...

The present invention provides a marine anchor that provides a high holding power and allows faster, smoother and more controlled penetration of the anchor in various soil types. The invention includes an anchor with a shank having two, rearwardly diverging legs that are coupled to the top surface of the fluke along two rearwardly diverging lines so that the plate-like legs define a soil passage that diverges rearwardly within all planes that are parallel to the surface of the fluke between the ...

An anchor with pivoted flukes and a track upon which an anchor line is slidably connected to the anchor has a pair of fluke drivers adjacent the flukes which produce a significant included angle of the flukes with respect to the bed of a body of water. This included angle of the flukes enables them to rapidly penetrate and set in a bed of a body of water even under hard pan bed conditions. Typically, the anchor sets into the bed of a body of water within ten feet of anchor movement relative to t...

A boat or ship anchor having a crown portion with a spaced apart pair of flukes projecting forwardly therefrom in the same plane, and a pair of tail plates extending rearwardly therefrom, the tail plates being splayed to present a large frontal area. Intermediate the flukes and extending through the crown is an aperture. A shank element, adapted for attachment to the anchor line at its forward end, extends through the aperture and is dimensioned for sliding relation in the aperture intermediate ...

A gravity anchor for a tethered buoyant platform comprises a container ballasted with a heavier than water ballast such as drilling mud. The anchor is installed by (a) floating the container in a buoyant condition with its interior volume containing air to the offshore installation site, (b) admitting water to, and expelling air from, the interior volume to reduce the buoyancy of the container so that the container is either of reduced positive buoyancy or negatively buoyant, (c) either pulling ...

An anchor adapted to develop high holding power in both hard and soft anchoring ground due to flaps which are retracted within the fluke area in hard ground and extended outside the fluke area in soft ground.

An anchor for ships and boats which upon lowering is partially embedded in the bottom of a body of water and is maintained in such position by the force applied by the water column bearing thereagainst.

The present invention provides: an anchor comprising a plough portion which is generally V-shaped in plan to taper from a broad portion at one end to a holding entering point at the other end, and which is generally V-shaped in cross-section transverse to the length of the plough portion between the ends, a shank attached to the plough portion and to which an anchor cable, chainrope or rode may be affixed, and tines extending from adjacent the broad portion of the plough portion in a generally f...

A device for an anchor comprising an anchor shank, which anchor is to be handled by means of a chaser. The chaser is paid out to the anchor along an anchor line on a separate chaser line and seized on the anchor. The device comprises means arranged for turning the anchor with the chaser resting on an abutment provided on said means. The means is included in the assembly of said shank and the anchor line, thus allowing an in-line, arrangement of said means, the shank and the anchor line.

An improved anchor which can be easily separated massive obstacles merely by pulling the anchoring line. The anchor comprises a shank having a crown end and a rotatable shaft attached to the crown end and extending substantially perpendicular to the longitudinal axis of the shank, at least one fluke mounted on the shaft, locking device for restricting the rotational movement of the shaft within an angular range so that the angle of the fluke relative to the axial direction of the shank is below ...
