Graphical Construction Glossary >> Doors. >> Door types >> Trap Door
A common term for any door set into a floor and hinged to open downwards under it's own weight.
I guess the term came about in the days press gangs and other criminal activity. It is said that Sweeny Todd had one for disposing of his victims. So the trap part comes from the fact that the door opens downwards and so anyone or anything on it will fall down below.
I doubt that any set of building regulations would allow one these days. So, just in case you are wondering what the door in the photograph is. It is the gallows door at Her Majesty's Gaol and Labour Prison in Fannie Bay, Darwin. Commonly known as Fannie Bay Gaol. It was used twice in 1952 for executions. The gaol remained operative until 1979,
So, if you are contemplating a door to your cellar of loft space, hinge it opening upwards! It's safer :-)
