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.

Abstract: A beverage container cooling device comprising a lower housing unit having an ice compartment area formed therein adapted to contain ice. The lower housing unit is provided with structure for centering the beverage container on the ice in a substantially horizontal attitude. A top housing unit is detachably secured to the lower housing unit and is provided with a horizontally disposed roller having a crank operatively secured thereto which extends outwardly through the top housing unit. The roller is vertically movably mounted in the top housing unit and is designed to engage the beverage container positioned on the ice so that operation of the crank will cause the roller to rotate the beverage container on the ice which will cause the contents of the container to be cooled.
