ABSTRACT:
An anchor retrieving device adapted to be interposed between an anchor and one end of a main anchoring line. The anchor includes a shank having a crown end and at least one fluke. The anchor retrieving device comprises: a lock assembly having an upper end connected to the one end of the main anchoring line and a lower end connected to the crown end of the anchor through an anchor-retrieving line; a releaseable hook member having one end normally locked by the lock assembly and the other end normally housed in the lock assembly at a position adjacent to the lower end of the lock assembly, the other end being connected through a connection line to the end of the shank opposite to the crown end; and a weight slidably engaging the main anchoring line and dropped downwardly along the main anchoring line to strike the lock assembly; the lock assembly including a housing for accommodating the releaseable hook member during the normal anchoring operation, a movable locking block housed in the housing for movement between a locking position and an unlocking position along the axial direction of the housing, and a spring normally biasing the movable locking block into its locking position and releasing the releaseable hook member when struck by the weight to allow the releaseable hook member to come out of the housing.
