A latch assembly having a base and a paddle. The paddle is rotatably connected to the base to pivot about a paddle axis and has a drive surface offset from the paddle axis. A catch pinion is rotatably connected to the base to rotate about a pinion axis that is generally perpendicular to the paddle axis. The catch pinion has an activation surface positioned such that movement of the drive surface generates a force on the activation surface to rotate the catch pinion about the pinion axis. The catch pinion may have a concave surface to receive a portion of the drive surface as the paddle rotates. A lock may be movably mounted to the paddle, and movable to engage a lock surface on the catch pinion to prevent the paddle from rotating. A lock may be provided to selectively disable the drive surface from rotating with the paddle.
