Abstract: A weatherproof sliding closure such as a window, door or hatch, especially suitable for closing openings in a marine environment, is disclosed. The closure is mounted top and bottom on bearing assemblies via camshafts extending through the closure and rotatably mounted in the assemblies. The bearing assemblies travel along fixed top and bottom guideways to move the closure between open and closed positions with respect to the closure opening. Cam portions of the shafts act against internal portions of the closure itself, serving as cam followers, when the camshafts are rotated in unison in the same direction through operation of a closure handle and drive train interconnecting the camshafts internally of the closure. This causes the closure to shift laterally on its bearing assemblies into sealing engagement with a closure frame defining the closure opening.

Abstract: A swinging-and-sliding door for vehicles which opens in two mutually perpendicular steps, a first step wherein it bends out of a doorway-closed position and into a ready-to-slide position and a second step wherein it slides aside horizontally into a doorway-open position.
