发明名称 PROTECTIVE COLD FRAME FOR PLANTS
摘要 Disclosed herein is a plant-protecting device which is commonly known as a protective cold frame. While this description seems to indicate a frame-like device, the described device is intended to refer not only to the frame but also to a wind and thermal protective covering generally configured to hold heat therein to protect a plant therein from cold, wind, and the combination. In general, the disclosed device comprises a plurality of rod members that may be bendable, which are inserted into a coupler at the apex of the dome-shaped frame to provide a support structure for a cylindrical covering to be placed thereupon.
