发明名称 Spa cover lifter
摘要 A device for removing spa covers and storing them, while the spa is in use, and returning them to cover the spa after use. The device may be operated with very little effort on the part of the user to lift the cover up and "off" the spa and over the end for storage. The spring balance aids in returning the cover to the "on" position. This device also reduces the possibility of having the wind damage or blow away the spa cover. Handicapped persons may find the installation of the hand crank or electric motor provisions will help them remove and replace the cover.
