IMPROVED BIFOLD SYSTEM
Abstract A bifold system comprising a frame comprising a jamb and a header together at least partially defining an opening; a track extending along the header in a transverse direction across the opening; a first panel having a first side and a second side opposite the first side, the first panel being hinged to the jamb at the first side of the first panel to pivot about a vertical axis spaced with respect to the track in a forward direction with respect to the frame; a second panel having a first side and a second side opposite the first side; at least one intermediate hinge connecting the first side of the second panel to the second side of the first panel, the at least one intermediate hinge enabling the first panel and the second panel to be moved between a closed configuration and an open configuration; a wheel connected to the second panel towards the second side of the second panel, the wheel being rotatably mounted on a vertical axis and configured to guidedly travel along the track, and wherein, when the first panel and the second panel are in the open configuration, the intermediate hinge offsets the second side of the first panel from the first side of the second panel by a spacing in the forward direction. 4a 24b 1b 2b 2a la Figure la
