A removable litter chair insert adapted to be used with a standard ambulance cot and effectively enables emergency personnel to remove patients from narrow or confined spaces such as when transporting patients from a second floor to a ground floor especially when it is necessary to negotiate steps and landings in the steps, narrow doorways, hallways and the like. The device includes a framework with a canvas type liner connected to the framework and a removable pad or mattress secured to the liner with the insert being capable of orientation in a straight line condition for use as a regular stretcher and convertable to a chair configuration to facilitate extrication of emergency patients from confined areas by ambulance personnel.

A litter chair insert for use with an ambulance cot and convertible from a straight stretcher to a chair configuration comprising a generally rectangular frame enclosing an open area, a flexible liner in the open area attached to the frame, said frame including a center section, a foot section and a head section, lockable hinge means interconnecting the center section and foot section and lockable hinge means interconnecting the center section and head section with the lockable hinge means enabling the sections to be oriented in alignment with each other to form a stretcher or in angular relation to each other to form a chair to enable a patient to be more effectively transported down stairways, through halls having confined areas and the like, each of said lockable hinge means including a female component and a male component, said female hinge component including an axial recess receiving an axial projection on the male hinge component, a transverse pin interconnecting said female hinge component and said male hinge component to enable the hinge components to move pivotally in relation to each other when moving between aligned and angular positions, and a locking member movably mounted on one of said hinge components in spaced but adjacent relation to the pin for locking engagement with the other hinge component in the aligned and angular positions of the hinge components, said locking hinge being confined to an area adjacent said transverse pin thereby leaving the areas above and below the frame unobstructed, said recess on the female hinge component and said projection on the male hinge component including engageable transverse surfaces parallel to and in spaced but adjacent relation to said pin for limiting pivotal movement of the female and male hinge components to an aligned position in one direction of pivotal movement and an angular position in the other direction of pivotal movement, said hinge component lockingly engaged by the movable locking member including transverse surface areas in addition to those limiting pivotal movement engageable by said locking member when said female and male hinge components are in their aligned and angular positions.
