Abstract
Segmented doors for closing a wide opening in an enclosure where the upper door is hinged to the top of the opening, the lower door is hinged to the bottom of the upper door and a wire bail is provided for the purpose of locking the lower door into a V-like or triangular relationship with the upper door. This V-like structure, composed of the locked-together upper and lower doors, can then be rotated upward to a stable triangular or inverted V-like position atop the roof or top panel of the cabinet.
