Roll-in futon bed

Abstract

An article of furniture is provided which can be transformed easily from a bed to a futon or a chaise lounge. The article of furniture is formed of a stationary, generally U-shaped upright support having a head frame with opposing ends from which side frames extend in mutual parallel alignment. A base frame assembly is mounted upon wheels or other roller elements and is comprised of a plurality or articulated frames, including a seat bench frame located remote from the head frame of the stationary support, and at least an intermediate seat back frame hinged to the bench frame. Preferably, a proximal back frame is also provided which includes within its structure a backrest that may be raised or lowered when the unit is used as a chaise lounge. The article of furniture is provided with rollers on each side of the stationary support near the distal extremities thereof. Cam latches are provided on opposing sides of the seat frame in longitudinal alignment with the rollers. The cam latches include concave downwardly facing seating recesses and cam surfaces that are inclined longitudinally and upwardly therefrom, toward the head frame. When the article is to be utilized as a futon, the seat bench frame is moved to engage the cam latches with the rollers so that the cam surfaces of the cam latches ride up the rollers and the seating recesses lodge on the rollers in releaseable latching engagement therewith when moved into registration with the rollers.
