Abstract

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 attached to the cover. 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.

a distal portion movably coupled with the motor;

a proximate portion of the frame member movably coupled with the biasing device; and

,

an integral arcuate-shaped portion disposed between the proximate portion and the distal portion.

9. The apparatus of claim 8 wherein the integral arcuate-shaped portion extends above the cover when the frame member is in the first position.

10. The apparatus of claim 1 wherein the motor moves the frame member such that the proximate portion of the cover is pivotally moved with the biasing device toward the distal portion of the cover when the frame member is moved from the first position to the second position.

11. The apparatus of claim 1 further comprising:

a second frame member disposed on an opposite side of the housing from the motor;

a second motor coupled to the second frame member for moving the second frame member in unison with the first frame member;

a cross frame member which extends across the cover and connects the frame member with the second frame member such that the frame member and the second frame member move in unison when moved by the motor and second motor; and

,

wherein the second frame member is pivotally connected to the proximate portion of the cover with a second biasing device.

12. An apparatus in combination with a conventional cover and a spa for lifting the cover off of the spa, the spa having a rim comprising:

a first frame member having a first frame member proximate end and a first frame member distal end, wherein the first frame member distal end is pivotally attached at a frame pivot location to an exterior of the spa, and wherein the first frame member proximate end is pivotally coupled to a shock absorber that is pivotally coupled with a proximate cover portion of the cover;

a stop attached to the exterior of the spa for preventing a generally lateral movement of a cover distal edge in a direction generally away from a proximate end of the spa; and

a motor coupled to the first frame member for moving the first frame member about the frame pivot location from a frame first position to a frame second position, and from the frame second position to a frame third position,

wherein the cover is disposed in a generally horizontal orientation over a top of the spa when the first frame member is in the frame first position,

wherein movement of the first frame member causes the proximate cover portion to be lifted with the shock absorber from the proximate end of the spa while a distal cover portion remains disposed in the generally horizontal orientation over a distal end of the spa when the first frame member is moved from the frame first position to the frame second position, and

wherein further movement of the first frame member causes the proximate cover portion to be lifted with the shock absorber from the proximate end of the spa and the distal cover portion also to be lifted from the distal end of the spa when the first frame member is moved from the frame second position to the frame third position, wherein the entire proximate portion of the cover and the entire distal portion of the cover are disposed on or above an imaginary plane defined by the spa rim when the first frame member is in the frame third position.

13. The apparatus of claim 12 wherein the first frame member has an integral arcuate-shaped portion disposed between the first frame member proximate end and the first frame member distal end, and wherein the arcuate-shaped portion extends above the cover when the first frame member is in the frame first position.

14. The apparatus of claim 12 wherein the motor is pivotally attached to the first frame member distal end at a motor attachment location on the first frame member distal end, and wherein the motor moves the motor attachment location of the first frame member in a direction generally away from the proximate end of the spa when the first frame member is moved from the frame first position to the frame second position.

15. An apparatus in combination with a conventional cover and a spa for lifting the cover from the spa, the spa having a rim comprising:
