US Patent 7971287 Method and apparatus for automatically lifting a cover

An apparatus for lifting a cover from a spa or other housing includes a frame member having one end that is pivotally attached to the exterior of the housing. Another end of the frame member is pivotally and slidably coupled to the cover. In one embodiment, the frame member is pivotally and slidably coupled to the proximate cover portion via a pin attached to the proximate cover portion and extending through a slot defined by the frame member. A motor is likewise attached to the exterior of the housing and is pivotally coupled to the frame member. The motor causes the frame member to rotate thereby lifting the cover off of the housing.
