发明名称 Lightweight anchor having high strength to weight ratio
摘要 A lightweight anchor in which each one of the flukes is made up of two sheets of stainless steel plate stock, stacked one on top of the other and welded together. Each sheet contains a plurality of integrally formed, longitudinally extending ribs and the inner and outer edges of each sheet are bent to form upwardly extending perpendicular flanges. The crown is a generally U-shaped member made out of stainless steel plate stock. The angle of rotation of the shank relative to the flukes is limited by a pin connected to the shank and extending into angular slots in support plates attached to the flukes. A pair of stainless steel U-shaped braces made out of bar stock are rigidly connected to the flukes to prevent yawning movement of the flukes and also serve as a back up mechanism for limiting the angular movement of the shank relative to the flukes. All the surfaces on the anchor are electropolished.
