ABSTRACT:
A boat dock assembly for retrievable extension into a body of water comprises a base section secured to the shore, a plurality of dock sections pivotally secured in an end-to-end relation by connecting hinges, legs attached to the forward end of each dock section for supporting the dock section above the surface of the body of water, and a rail system for rolling the dock sections out of the body of water by pivoting each dock section in one direction about the respective dock hinge into a spiral configuration adjacent the base, commencing with the last dock section, and for unrolling the dock sections from the spiral configuration into the body of water by sequentially pivoting each dock section in the opposite direction about the dock hinges, commencing with the first dock section. The legs which are longer than the dock sections to which they are attached have at least one knee joint to permit the legs to fold when the dock sections are rolled into the spiral configuration. A locking pin locks the knee joint to prevent folding of the leg when the dock is in the extended position in the body of water. A foot element on the bottom of each leg allows the effective length of the leg to be adjusted from the dock surface and allows the leg to be easily raised from the bottom of the body of water without suction being created between the foot member and the bottom of the body of water.
