Folding-door comprised of wooden slats and hinges

A folding door of the type wherein an array of wooden slats are hingedly connected together at adjacent vertical edges, comprising vertical wooden hinge strips each having a horizontal cross-sectional shape substantially in the form of a double mushroom with a central stem and oppositely disposed heads of different widths separated by side recesses, at least two longitudinally spaced apertures through said stem, said adjacent vertical edges of said slats having a horizontal cross-sectional shape in the form a U with legs of different lengths to thereby form a longitudinal slot in each said vertical edge, hinges for connecting said slats together each having a central part and oppositely disposed side parts hingedly connected to said central part, said central part being disposed and latched within one of said apertures in said strip, and said side parts being inserted and latched in said adjacent vertical edges of said slats, said strips, slats and hinges being assembled together so that when the door is in the unfolded position, the longer legs of said slat edges are received in the adjacent side recesses of said strip and the shorter legs of said slat edges each lie closely adjacent the narrower head of said mushroom shaped strip so as to appear to be a continuation thereof, and when the door is in the folded position, said longer legs are disposed alongside the adjacent said narrower head to substantially conceal said side recesses, said slates rotating substantially about the vertical side edges of said narrower head.
