Abstract
A low profile hospital bed includes a mattress support frame and pivotably mounted wheel frames. Lift actuators connecting between the mattress support frame and the wheel frames move the wheel frames between a folded position and an unfolded position. When the wheel frames are in the folded position, the lift actuators are relatively horizontal and thus unable to provide enough vertical force to move the wheel frames. Accordingly, connecting between the actuators and the wheel frames are leverage members which rotate and urge the wheel frames away from mattress support frame during an initial, first stage of movement as the wheel frames partially unfold. After the first stage of movement, the leverage members function as simple mechanical links between the lift actuators and the wheel frames as the lift actuators continue to power the complete unfolding of the wheel frames.
