An anchor includes an anchor shank, a fluke disposed on the leading terminal side of the anchor shank as folded back therefrom, and a buoyancy part disposed on the leading terminal side of the anchor shank. The buoyancy part has a buoyant force that causes the leading terminal side of the anchor shank to rise upward and the basal terminal side thereof to contact the water bottom when the anchor is positioned on the water bottom, allows the leading terminal part of the fluke to remain in contact with the water bottom under its own weight, and enables the fluke to retain a posture for forming a given inserting angle relative to the water bottom.
An anchor comprising an anchor shank, a fluke disposed on a leading terminal side of said anchor shank as folded back therefrom, and a buoyancy part having a bottom surface fixed onto the leading terminal side of said anchor shank, said buoyancy part having a buoyant force that causes the leading terminal side of said anchor shank to rise upward and a basal terminal side thereof to contact a water bottom when the anchor is positioned on the water bottom, allows a leading terminal part of said fluke to remain in contact with the water bottom under its own weight, and enables said fluke to retain a posture for forming a given inserting angle relative to the water bottom.

1. Field of the Invention
This invention relates to an anchor for use with a small boat.
2. Description of the Prior Art
FIG. 1 is a perspective view illustrating one embodiment of the anchor of this invention.
FIG. 2 is a side view of the anchor shown in FIG. 1.
FIG. 3(a) is an explanatory diagram depicting the anchor of this invention posed on the water bottom.
FIG. 1 and FIG. 2 illustrate one embodiment of the anchor contemplated by this invention for use with a small boat. An anchor 1 comprises an anchor shank 2 and a fluke 4. The leading terminal side 2a of the anchor shank 2 and the basal terminal part 4b of the fluke 4 are joined in the form of a return bend. A buoyancy part 5 is attached through attaching members 6 to the leading terminal side 2a of the anchor shank 2.
In the embodiment of FIG. 1, the buoyancy part 5 is fixed to the anchor shank 2 using two strap-shaped attaching members 6. However, the attaching members 6 may have a different shape.
The leading terminal side 2a of the anchor shank 2 is selected as the site for attachment of the buoyancy part 5 to the anchor shank 2. This selection results in facilitating the adjustment of the posture of the anchor in the water. The expression “the leading terminal side 2a of the anchor shank” as used herein means the position of the anchor shank 2 that is approximated to the side of the fluke 4 as illustrated in FIG. 2. By the same token, the expression “the basal terminal part 4b of the fluke” means the position of the fluke 4 that is approximated to the side of the anchor shank 2 and the expression “the leading terminal part of the fluke 4” means the opposite of the basal terminal part thereof, namely the leading terminal part 4a which is fastened to the water bottom.
