Abstract
The invention provides an adjustable bed frame having a main support including head and foot ends. The support is movable between raised and lowered positions and independent first and second elevating mechanisms are coupled to the main support. The mechanisms are spaced from one another on the main support to carry the bed frame on a support surface. An electrical supply system provides power to actuate the mechanisms to change the height of the main support above the support surface and a controller is coupled to the supply system to selectively activate the first and second elevating mechanisms to move the main support between raised and lowered positions. DC motors and worm drives are used independently to drive the elevating mechanisms and stops are provided at the raised and lowered positions to ensure that the main support is horizontal in the raised and lowered positions.
