Patent Images
1. An articulated bed with an expandable frame, comprising:
- a generally rectangular main frame adapted to fixedly receive a stationary panel of an articulated mattress support having at least one other panel pivotally mounted to the fixed panel, a drive motor fixed to the main frame and a linear device driven by the motor, a pivot arm on the main frame driven by the linear drive positioned to pivot the pivotally mounted mattress panel, and an extendable co-planar frame carried by the main frame movable from a first position mounted within the main frame to a second extended position defining with the main frame the entire support for the mattress support.

Abstract
An improved articulated bed with linearly retractable head and foot sections for easier shipment in a relatively small container that may be assembled by the purchaser without any tools. The bed includes a central frame with telescopic head and foot sections that linearly retract into the central frame. The central frame houses the head and foot drive motors, linear actuators, and rocker shafts that pivot mattress support panels upwardly from the extended frame.

6. An articulated bed having a horizontally expandable frame, comprising:
- a generally rectangular main frame, a head frame telescopically carried by the main frame and movable from a first position mostly within the main frame to a second extended position defining the frame for the head end of the bed, a foot frame telescopically carried by the main frame and movable from a first position mostly within the main frame to a second extended position defining the frame for the foot end of the bed, a foldable mattress support releasably mounted on the frame including a seat panel fixedly carried by the main frame, a head panel pivotally carried by the seat panel and engageable when lowered with the head frame, a foot panel pivotally carried by the seat panel and engageable when lowered with the foot frame, first and second rocker shaft and arm assemblies for pivoting the head and foot panels, and motor means for driving the first and second rocker shaft and arm assemblies.
