Abstract
The present invention relates to an apparatus, such as a bed, having a vertically adjustable deck that is selectably raised and lowered in a substantially vertical manner. Two leg frames are pivotally and movably connected to rails supporting the deck through a slot in the bottom of the rails. Support frames having a fixed longitudinal position relative the bed frame rail are connected to a central pivot point of the leg frames, respectively. The support frames each have a cross member supporting a connection lever defining a path. Actuators are pivotally connected to the bed frame and to a movable pivotal connection point along the path. A control arm is provided to determine the location of the actuator end relative the path of the connection lever. Wheel assemblies can be pivotally connected to the second end of the leg frames.
