AbstractAn adjustable care bed includes a base frame which supports a mattress frame. The mattress frame includes a head section, a seat or intermediate section and a foot or leg section all of which are pivotally interconnected. A first link and positioner subassembly interconnects the head section with the seat section. A second link and positioner subassembly interconnects the seat section with the leg or foot section. Each link and positioner subassembly includes a link fixed to one of the sections and having a free end. A bracket is fixed to the intermediate section. An elongated rod has an end pivoted to the bracket and a free end which extends through a lock housing. The lock housing is pivoted to the free end of the fixed link. A lock mechanism selectively locks or positions the rod with respect to the lock housing. The bed further includes an extendable caster subassembly, and a hi/low mechanism for raising the mattress frame with respect to the base frame, and a leg lift mechanism.
