Modular high-low adjustable bed bases retrofitted within the volumes of, and cooperatively operative with, diverse existing contour-adjustable beds so as to create high-low adjustable contour-adjustable beds

A high-low base retroffitable to and susceptible of integration with a contour-adjustable bed having a peripheral space frame to the end of raising and lowering the contour-adjustable bed in elevation above a floor, the high-low base comprising:

• a lower member (i) fitting completely within a volume and an area of the peripheral space frame of the contour adjustable bed while (ii) resting on the floor, the lower member subtending sufficient area while so resting so as to form a stable base;
• an upper member attaching to the underside of the peripheral space frame of the contour adjustable bed within the volume and within the area of this peripheral space frame;
• a plurality of linkage arms pivoting relative to each of the upper member and the lower member and connecting therebetween so as to, upon forcibly assuming different positions, locate the upper member and the lower member to different distances of separation one to the other,
• a cable for transmitting force to plurality of linkage arms, and
• a motor for providing the force transmitted through the cables to the linkage arms in order to, by locating the upper member and the lower member to different distances of separation one to the other, raise and lower the contour-adjustable bed;
• wherein each and all of the lower member, the upper member, and the elevation means fit within the volume and within the area of the peripheral space frame of the contour-adjustable bed.

A high-low base retroffitable to and susceptible of integration with a contour-adjustable bed having a rectangular peripheral space frame to the end of raising and lowering the contour-adjustable bed in elevation above a floor, the high-low base comprising:

• four upper members each of which fits to a respective corner of the rectangular peripheral space frame of the contour-adjustable bed so as to insubstantially increase a volume and an area of this peripheral space frame, the four members essentially being within the volume and within the area of the peripheral space frame;
• a first plurality of lower members disposed on the floor under the four upper members substantially in a shadow of the peripheral space frame;
• and
• a second plurality of elongate elevation means, connecting between the first plurality of lower members and the four upper members within the volume and within the area between them, for variably controllably extending in length so as to locate the four upper members at different distances of separation from the plurality of lower members thereby to raise and to lower the contour-adjustable bed having the peripheral space frame that is attached to the four upper members;
• wherein because the four upper members insubstantially increase the volume and the area of the peripheral space frame, because the first plurality of lower members are substantially in the shadow of the space frame, and because the second plurality of elongate elevation means connect between the first plurality of lower members and the four upper members, the entire high-low base is insubstantially larger in area upon the floor than the contour-adjustable bed that it serves to lift.
