ABSTRACT:
A door includes two door panels pivotally coupled together so that the door panels are rotatable relative to each other. A roller is disposed on an upper end of two distal posts and is guided to slide along a guide rail. A cylinder is fixed on each end of one of the distal posts. A rod is fixed to the roller and extends through an upper cylinder. The lower portion of lower cylinder is rotatably received in a hole and can be easily disengaged from the hole when the distal post is pulled upward.
