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 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.

Claims

An apparatus for lifting a cover from an opening of a housing having an exterior and an interior, wherein the housing further has a housing proximate end defining a proximate portion of the opening and a housing distal end defining a distal portion of the opening, wherein the cover has a proximate portion of the cover pivotally connected to a distal portion of the cover, wherein the proximate cover portion is adapted to cover the proximate portion of the opening, and wherein the distal cover portion is adapted to cover the distal portion of the opening, the apparatus 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 the exterior of the housing, and

wherein the first frame member proximate end is pivotally and slidably coupled to the proximate cover portion of the cover; and

a motor coupled to the first frame member and adapted to rotate 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 proximate cover portion is disposed in a generally horizontal orientation over the proximate portion of the opening and the distal cover portion is disposed in a generally horizontal orientation over the distal portion of the opening when the first frame member is in the frame first position,

wherein the proximate cover portion is lifted from the proximate portion of the opening and the distal cover portion is disposed in a generally horizontal orientation over the distal portion of the opening when the first frame member is in the frame second position, and

wherein the proximate cover portion is lifted from the proximate portion of the opening and the distal cover portion is lifted from the distal portion of the opening when the first frame member is in the frame third position;

wherein the first frame member proximate end defines an elongated slot and wherein the apparatus further comprises a pin attached to the proximate cover portion of the cover and extending through the elongated slot for longitudinal movement therein.

2. The apparatus of claim 1 wherein the cover has an upper surface and a lower surface, and wherein no part of the first frame member extends above the upper surface of the cover when the first frame member is in the frame first position.

3. The apparatus of claim 1 wherein the cover has an upper surface and a lower surface, wherein the first frame member has an arcuate-shaped portion disposed between the first frame member proximate end and the first frame member distal end, and wherein no part of the arcuate-shaped portion extends above the upper surface of the cover when the first frame member is in the frame first position.

4. The apparatus of claim 1 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 is adapted to move the motor attachment location of the first frame member in a direction generally away from the housing proximate end when the first frame member is rotated from the frame first position to the frame second position.

5. The apparatus of claim 1 wherein the housing has a housing rim defining the opening of the housing and further defining an imaginary plane extending beyond the housing, and wherein the proximate and distal portions of the cover are disposed on or above the imaginary plane when the first frame member is in the third position.
