Abstract
The invention has as its object a drag anchor which is simple to manufacture and provides an effective grip in the bottom material where the anchor is to be used, besides which the anchor can be executed with a very low weight. The invention, which relates most particularly to a drag anchor, the shank of which is pivotally attached to its part which forms the fluke, is characterized in that its part (2) which forms the fluke consists of a hollow body (2) open at its front and rear end in the direction in which the shank (1) is towed, i.e. the direction of movement of the drag anchor, which body forms a mantle enclosing the rear part of the shank with an extension in the direction of movement of the drag anchor.
Claims20
A drag anchor, the shank (1;
- 21) of which is flexibly attached to the part (2;
- 22) which forms the fluke, characterized in that the part (2;
- 22) which forms the fluke consists of a hollow body open at its front and rear end in the direction (41) in which the shank (1;
- 21) is towed, that is to say the direction of movement of the drag, which hollow body forms a mantle enclosing the rear part of the shank, said shank extending in the direction of movement of the drag, and in that the shank (1;
- 21) is articulated in one plane and is attached to the mantle (3-6;
- 23-26) via a bearing device (11;
- 31) spanning its internal cavity centrally, taken in a transverse section relative to the direction of movement (41) of the drag, which bearing device consists of a wall said wall having at least one flat surface (11;
- 31) dividing the internal space of the hollow body and extending in the direction of movement (41) of the drag anchor and is so arranged as to provide lateral support for the shank (1;
- 21).
