<p>A folding door 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 the stem, said adjacent vertical edges of the slats having a horizontal crosssectional shape in the form of a U with legs of different lengths to thereby form a longitudinal slot in each vertical edge, hinges for connecting the slats together each having a central part and oppositely disposed side parts hingedly connected to the central part, the central part being disposed and latched within one of the apertures in the strip, and the side parts being inserted and latched in the adjacent vertical edges of the slats, the strips, slats and hinges being assembled together so that when the door is unfolded, the longer legs of the slat edges are received in the adjacent side recesses of the strip and the shorter legs of the slat edges each lie closely adjacent the narrower head of the mushroom shaped strip so as to appear to be a continuation thereof, and when the door is folded, the longer legs are disposed alongside the adjacent narrower head to substantially conceal the side recesses, the slats rotating substantially about the vertical side edges of the narrower head.</p> |
