  • Closure latching mechanism
    Patent number: 5848575
    Abstract: The door, hatch or other closure in a marine vessel includes a large central window, and is manually or mechanically latched or unlatched by a quick-acting actuation mechanism. An outer handle or an inner handle is rotated, thereby pulling a chain that engages each of a plurality of sprockets. As the chain is pulled, each of a plurality of dogs rotate to engage or disengage a corresponding number of strikers attached to a jamb. Sprockets having different diameters may be utilized to vary the rate of rotation of different dogs and to vary the force applied to different dogs. The position of dog is visually identifiable from the position of the handles.
