摘要：
A spring drive system includes a housing, an extendible window cover coupled with the housing, and at least one lift cord coupled to the cover for raising and lowering the window cover. A spring drive system comprises a first spring drive spool spaced apart from a second spring drive spool and at least one spring having a storage end coupled to one of the spring drive spools and an output end coupled to the other of the spring drive spools. A first cord spool has a first cord spool axis. The lift cord extends from the first cord spool to the window cover for assisting in raising and lowering of the cover, and the spring drive system affects rotation of the first cord spool about the first cord spool axis and has no external hand-operated control cord input to raise and lower the window cover.
