Abstract of the Disclosure
A cold frame characterized by being compactly stackable, readily
pivotable between a lowered operative position and a lifted position to
give practical access to the plant, and by having a transparent cover
material which is readily removable and replaceable. This cold frame
comprises a rod framework of the shell-like type including a closed
perimeter open frame forming a base having a pair of opposite sides,
transparent plastic hood operatively covering the rod framework and
having a hem peripherally extending along the closed perimeter frame,
and pegs pivotally connected along one of the opposite sides of the
perimeter shape base and anchorable in the ground to selectively pivot
the framework and plastic hood relative to the ground. The plastic
hood is removably secured by retaining rods engaging in the hem and
releasably securable to the closed perimeter frame. The rod framework
is opened at the base and has lateral side walls outwardly inclined
relative to and toward the base.
