Abstract

A sliding hinge for mounting a nose cone or cover on a nacelle or housing, such as an equipment package suspended from the wing of an aircraft. Typically two hinges are used, positioned at opposite sides of the housing, for pivoting the nose cone upward to provide access to the equipment within the housing. Each hinge includes a sleeve mounted in the housing, a slide block sliding in the sleeve, and a slide arm pivotally attached to the slide block and mounted in the nose. To open the package, the nose is initially slid forward from the housing and then pivoted to an upward position. During this operation the slide arm slides out of the sleeve from a retracted position to an extended position and then pivots upward to the open position, with the slide block remaining in the sleeve. A locking mechanism is provided for locking the slide block in the sleeve in the extended position so that the nose cover has to be pivoted downward to the horizontal position in alignment with the housing before the arm and nose can be moved toward the housing to the retracted position.
