Ground anchors, in particular tent stakes (100), comprise one or more inherently flexible tines (110), a ground compression plate (160), and various tie points (420, etc.) for attaching a guy rope or the like to the top of anchor. The compression plate extends perpendicularly or at a large angle to the tine so that when the guy rope pulls on the anchor, the tine will tend to rotate about an underground fulcrum so that the compression plate will press against the ground and help the anchor resist...

An anchor system has two anchor members pivotally connected and spaced apart head to tail. The anchor member tied to the line is larger than the terminal anchor. The tail of the tethered anchor member rests on the head of the terminal anchor member to stabilize the anchor system when it is deployed and resting on the bottom of a body of water.

The present invention provides an improved anchor which is capable of being readily laid, irrespective of the holding or anchorage involved. The anchor includes a first fluke or base member (2), an elongate shank member (9) to which at least one anchor line or chain may be attached, and a second fluke (20) from and disposed substantially parallel to the first fluke (2) but is of a smaller size than the first fluke (2).

A raft which has an anchoring system which holds the raft in position in a swimming pool, and which also has a securing portion for holding an anchor.

Anchor fluke (1) having a hollow plate-shaped body adapted for attachment to a shank and/or anchor lines, with a longitudinal axis and a front penetration edge (3) and a rear trailing edge (4), which are located at a distance from one another in the direction of the longitudinal axis, wherein the fluke has a plane of symmetry that contains the longitudinal axis and is substantially perpendicular to the plate-shaped body. The hollow plate-shaped body has an upper surface (2a) with a centre of gra...

The present invention relates to a floating support of the type having a cavity (1) within which a plurality of risers (2) can be positioned. According to the invention, the cavity (1) has a plurality of compartments (3) at the ends of which said risers (2) are in a production position (4), said compartments communicating with a central channel (5) at the end of which there is situated (6) a drilling derrick (7), said compartments being disposed transversely relative to said central channel (5).

An anchor for personal watercraft provides a generally cylindrical housing closed at a top end and enclosing a concavity formed through the opposite, bottom, diametral end. The opening of the concavity is defined by a circumferential edge of the housing, and may be further shaped or formed with a circumferential edge or with a central and/or a plurality of circumferential spikes to readily engage with any of a variety of materials found on the floor of a water body or beach. A weight may be remo...

A marine anchor designed so that it positions itself automatically and penetrates instantly into all kinds of sea beds with maximum holding power. The geometry and ballasting of the anchor ensure automatic positioning of the anchor. The off-center position of the ballast counter-balancing the weight of the shank places the center of gravity of the anchor as close as possible to the anchor tip, so that the tip can bear practically half the total weight of the anchor, the pressure exerted by the t...

An assembleable anchor-type landscaping device which is lightweight, durable, and capable of being moved and shipped with minimal expense. The anchor device comprises a detachable connected ring, a hollow shank which is formed in multiple portions which are removably connected, a hollow removable stock, hollow and removable arms, and detachable fluke members (optionally hollow). The anchor may be variably filled with a ballast material to achieve appropriate landscaping weight.

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...
