ABSTRACT:
A portable folding bed cabinet having a vertically elongated frame and a pair of horizontally spaced mattress frames that are attached to the vertically elongated frame. The vertically elongated frame has vertical side frame members having tracks along their inner surfaces for guiding counterweight panels that extend across the back of the vertically elongated frame. The counterweight panels are connected at their opposite ends to the mattress frames by a pair of link arms. The link arms are pivotally attached to each other with one link arm pivotally connected to the counterweight panel and the other link arm fixedly attached to the mattress frame. A leg assembly is also attached to the opposite ends of the lower mattress frame and these leg assemblies retract when the mattress frame is folded into its upright stored position. Each leg assembly has a leg and a pair of link arm members. The legs are in the form of bellcranks that are pivotally mounted at their centers on a shaft that passes through the mattress frame into cam members mounted on the inner surface of the mattress frames. As the bellcrank shaped legs are pivoted around their shafts, they withdraw into recesses formed into the end of the mattress frame. A retainer frame is detachably secured to the top mattress frame. A ladder has pins extending from the rear surface that interlock in slots formed in the mattress frames to function as a brace member and also a means of access to the upper bed.
