ABSTRACT:
A vertically adjustable bed includes a bed frame attached to movable legs powered by a motor. Operation of the motor causes the legs to move longitudinally along a guide rod, collapsing the legs beneath the bed and moving the bed frame vertically. Collapsing the bed to its substantially lowermost position compresses a spring. The energy stored by the compression of the spring is used to raise the bed from its substantially lowermost position. Pivotally attached to the legs is a caster and foot arrangement. During normal operation, the foot engages the floor. When the bed frame moves to its substantially uppermost position, a pin extending from the leg engages one end of a slot, causing the caster to pivot and engage the floor, rendering the bed horizontally mobile.
