Abstract: A collapsible cleat assembly positionable selectively into a stored position defined by a cleat member disposed into the interior of a cavity integrally formed in a mounting base wherein the cleat member is substantially flush with an outer exposed surface of the mounting base so as not to provide any significant protrusion above the surface of the deck or dock in which the cleat assembly is mounted. The cleat member is selectively pivotal substantially 90 degrees out of the cavity into an operative, upstanding position above the deck or dock surface for attachment and retention of a mooring line or the like and further wherein the mounting base including the cavity is set into a formed recess within the deck surface or dock surface on which the cleat assembly is mounted so as to transfer, at least in part, stresses or focuses to the entire mounting base rather than the connecting structure for securing the cleat movably to the mounting base.
