A latch assembly for use as a closure device in a door or compartment cover has a pan adapted to be flush mounted in an exterior panel, with a paddle-type handle hinge mounted within a recessed area of the pan. A mounting plate on an interior side of the pan includes a latch mechanism mounting flange which extends away from the pan, and to which a latch mechanism having a pawl and a trip latch jaw is mounted. A cam is rotationally mounted tightly parallel against the mounting plate, and has a paddle contact pin which extends through cooperating openings in the mounting plate and a floor of the pan. Lifting of the paddle causes the cam to rotate and engage the pawl of the latch mechanism, thereby releasing the trip latch jaw from a locked position. A lock cylinder may be mounted in the pan with a locking cam positioned proximate to a portion of the cam, to thereby interfere with rotation of the cam. The rotational mounting of the cam tightly against the mounting plate occludes the cooperating openings in the mounting plate and pan floor to prevent the passage of moisture or foreign objects to the interior of the latch assembly.

[ What is claimed as the invention is:] [1.] A latch assembly adapted for installation in an openable closure such as a door or compartment cover and operable to engage a striker to hold a closure in a closed position and to release engagement with a striker to allow the closure to be opened, the latch assembly comprising:a mounting pan having a peripheral flange and side walls and a floor which define a recessed area in which a paddle is rotationally hinge mounted upon a hinge pin which traverses the recessed area of the pan, the paddle having an actuation tab proximate to an exterior side of the floor of the pan,a mounting plate attached to the pan on an interior side of the floor of the pan, the mounting plate having a major flat portion and a latch mounting flange which extends out of a plane of the major flat portion and generally away from the floor of the pan,a cam having a generally planar portion pivotally attached to the mounting plate so that the cam rotates in a plane closely parallel to and substantially flush against the major flat portion of the mounting plate, the cam also having a pawl contact arm which extends from the planar portion and which is located proximate to a pawl of a latch mechanism mounted on the latch mounting flange of the mounting plate, and a paddle contact pin which extends from the planar portion of the cam through openings in the mounting plate and the floor of the pan for contact with the actuation tab of the paddle, the planar portion of the cam substantially covering the openings in the mounting plate and the floor of the pan,the latch mechanism having a pawl rotationally mounted within a housing and operably engaged with a trip latch jaw also rotationally mounted within the housing and spring biased to an open position whereby rotation of the pawl induced by contact with the pawl contact arm of the cam allows the trip latch jaw to rotate to the open position to thereby release the latch from engagement with striker.
