Abstract:
A watertight door apparatus includes a door, a door frame, a number of dogging elements, and an actuator mechanism for toggling the dogging elements between a latched condition and an unlatched condition. The dogging elements include roller elements for reducing friction between mating parts. A detent mechanism is provided to prevent inadvertent operation of the actuator mechanism. The dogging elements can be configured to rotate into and out of the latched condition, or they can be configured to slide into and out of the latched condition.
