Researched patent designs and hinges for tilting sunroof.

Sunroof and moonroof patent designs and schematics. The sunroof already operates in a limited depth of the car body and changes plains to withdraw the cover to provide an opening. The same motion that lowers the sunroof arms will then pull the whole cassette back.

Trapdoor examples use hydraulic pistons and quick release latches.

    Sliding hinges used in windows uses the same forward force that swings the window out  also moves it center. I want to adapt this design to have the whole arm slide on a track to prop the base of my trapdoor to the stage.
