Abstract
An adjustable bed includes a universal, or interchangeable, bed end that can be used at either end of the bed and that can be connected with a motor drive assembly. The bed end may include a manual crank that is removably attached to the bed end. The bed end may include an elevating mechanism that includes a cross-beam or similar structure for transmitting motive force between fixed and movable portions of the bed end. The bed end may also include a new slip nut for transmitting motive force from a lead screw. The bed may further include a reversible corner plate for allowing the bed end to be used facing in either direction. The bed end may also include a plastic cover that is washable and scratch resistant.

13. A bed end for an adjustable height bed having a driveshaft that is rotatable in first and second opposite directions of rotation about a first axis to raise and lower said bed, said bed end comprising:
-
a movable portion for supporting a portion of a bed spring; an output shaft rotatable about a second axis transverse to said first axis; and a gearbox connected with said output shaft for transmitting rotational force from the driveshaft to the output shaft; wherein said gearbox can be coupled with the driveshaft in a first condition receiving rotational force from the driveshaft in a first direction of rotation about said first axis and effecting rotation of said output shaft about said second axis in a direction so as to raise said movable portion of said bed end; and wherein said gearbox can be coupled with said driveshaft in a second condition receiving rotational force from the driveshaft in said first direction of rotation about said first axis and effecting rotation of said output shaft about said second axis in a direction so as to lower said movable portion of said bed end; wherein said gearbox includes first and second input shafts, said first input shaft being coupled with the driveshaft when said gearbox is in the first condition and said second input shaft being coupled with the driveshaft when said gearbox is in the first condition.
