Abstract: A protective cover has a first and a second section that have adjacent panels in the section connected to one another by a laterally oriented expandable joint. Each laterally oriented expandable joint in the second section is placed on an opposite side of the cover relative to its corresponding adjacent lateral expandable joint in the first section. Within each section, every odd-numbered laterally oriented expandable joint lies on a same face surface of the cover and every even-numbered laterally oriented expandable joint lies on the opposing face surface of the cover. The laterally oriented expandable joints permit accordion style folding and unfolding of the panels. A longitudinally oriented expandable joint connects the first section to the second section and permits compact folding of the second section onto the first section.
