that rotation of the shaft 50 would rotate the pawl 90 into a position to cause closure between the door and a mating surface on the surrounding frame or alternatively into a position behind the door so that the door may be opened relative to the surrounding frame similarly axial movement of the shaft 50 causes the pawl 90 to move in the axial direction so that when the shaft 50 is drawn upward toward the latch housing 15 the pawl 90 cinches down on the mating surface of the surrounding frame and create a tight seal between the door and the frame additionally the application may or may not involve a gasket not shown between the door and frame either way the rotary and axial movements of the locking shaft 50 are translated to the pawl 90 which is mounted on or fixed to the shaft 50 0024 fig3 illustrates an exploded view of an embodiment of the present invention showing a latch housing 15 comprising a first chamber 20 and a second chamber 30 and a generally longitudinal recess 14 intermediate the two chambers a plug or retainer unit 40 is rotatably housed in the first chamber 20 on its upper.
