CA 2565204
The present invention provides a door system (1) comprising a reel (10), a door (2) interconnect at a first end to the reel (10) for winding and unwinding thereupon and one or more guide channels (8). The reel (10) is rotatably mounted on a lever (24) which is pivotally mounted to a pivot axis (P). Thus the reel (10) can pivot about the pivot axis (P) to ensure that, during operation, the point (E) at which the outer layer of the door (2) engages/disengages with the penuitimate door layer remains in the same general location with respect to the guide channels (8) and accordingly, the angle (if any) at which the door (2) enters the guide channels (8) remains constant throughout operation.
