Abstract:
A door assembly adapted for spanning an entrance of a shower room having first and second upright walls that extend upwardly from a horizontal ground surface, said door assembly comprising:an elongated rail member adapted to be disposed horizontally between the first and second upright walls and to be spaced apart vertically from the ground surface, said rail member being formed with a longitudinally extending slide channel; anda foldable sliding door unit includinga plurality of vertically disposed elongated connectors, each of said connectors having an upper end to be disposed adjacent to said rail member, and a lower end to be disposed adjacent to the ground surface, each of said connectors further having left and right sides formed with longitudinally extending left and right engaging grooves, a first one of said connectors being located at one end of said door unit and to be disposed adjacent to the first upright wall, a second one of said connectors being located at the other end of said door unit,connector mounting means adapted for mounting said first one of said connectors on the first upright wall,a plurality of vertically disposed elongated slats, each of said slats having two lateral end portions which are formed respectively with vertically extending cylindrical members, said cylindrical members on each of said slats being received in an adjacent pair of said engaging grooves of an adjacent pair of said connectors such that said cylindrical members are rotatable axially for folding and unfolding of said slats relative to the adjacent pair of said connectors, each of said slats having an upper edge adjacent to said upper ends of said connectors, and a lower edge adjacent to said lower ends of said connectors, anda plurality of slidable coupling units mounted on said upper ends of selected ones of said connectors and extending into and slidable along said slide channel so as to permit movement of said door unit toward the second upright wall to an unfolded state, where said connectors and said slats are disposed on substantially the same vertical plane to close the entrance to the room, and so as to permit movement of said door unit away from the second upright wall to a folded state, where said connectors and said slats cease to be disposed on substantially the same vertical plane to open the entrance to the room.
