A seat cushion frame 26 is composed of a peripheral frame member with a rigid sheet member 26~ extending thereacross having the fabric covered foam cushion 20 secured thereto.
The cushion support frames 19 and 26 are pivotally secured to one another by a pair of offset pivots, see Figure 7 o O-e the drawings.
Referring now to Figure 7 of the drawings, the offset pivots 29 can clearly be seen secured to the adjacent ends of the cushion support frames 19 and 26 with the pivot poin-t indicated at 29A. The pivot 29 can include a ratchet lock device, not shown, well known in the art that would provide a positive engagement between the cushlon support frames allowing the user to lift up on the free end of said cushion support frame 26,engaging the ratche-t and by pushing downwardly li-et the cushion support frame 19 at its pivots 23 allowing a seat structure 30 to be moved between the arms 10 as seen in Figures 1 and 2 of the drawings. The movable seat structure 30 comprises a base 31 having -four vertically extending sidewalls 32 and casters 33 are secured to the base 31. The seat cushion support frame 26 is pivotally secured at one end to said movable sea-t structure 30 by a hinge 34.
Referring now to Figures 4,5 and 6 O-e the drawings, a 28 pair o e cushion guide bars 35 can be seen secured to the ~7~
inner edges 36 respec-tively of the cushion suppor-t frame 18 adjacent its eree end. Each O r the guide bars 35 are secured to the inner edges 36 at their ends with the majority of -the bar being offset -therebetween as best seen in Figure 5 O.e the drawings. A cushion guide loop 37 extends erom a secondary U-shaped cushion support frame 38 secured only to the free end portion o-E the cushion 20. The guide bars 35 and guide loops 37 maintain alignment of the cushion 20 as it moves relatively to the cushion support frame assemblies 18 and 19 allowing the cushion 20 to extend outwardly from said cushion support frame assembly 18 supported by the secondary U-shaped cushion support -frame 38 as clearly seen in Figures ~ and 5 of the drawings.
Referring now to Figures 1,2 and 3 of the drawings, it will be seen that in order to open the folding chair to form a bed, the user pulls the movable sea-t structure 30 outwardly from the area between the arms 10 which action will move the cushion support frame assemblies 18, 19 and 26 forwardly. ~Yhen -the movable seat structure 30 20 is fully extended, the cushion suppor-t frame assemblies 18 and 19 are horizontally positioned in end -to end relation and supported between and on the tubular frame member 12, a pai.r Oe oppositely disposed projections 39 on.the inner surfaces ofsaid arms 10 and the movable seat structure 30 with the cushlon support frame assembly 2~ eorming a cushioned horizon-tal sleeping sur:Eace.
A pair of opposi.tely disposed seat wedges ~0 are
2~ positioned on the bottom of the seat cushion support frame ~23L7~
26 with the direction o-f inclination of -the wedge facing inwardly towards the back cushlon support frame assemblies 18 and 19. In use, the seat wedges ~0 engage the arm projections 39 elevating the respective end of the seat cushion suppor-t frame 26 when the folding bed chair is in its closed position. As the bed chair is opened, the ' seat wedges 40 move along and off of the arm projections 39 providing a flat surface as seen in ~igure 3 of the drawings.
In extended or open position, one end of the seat suppor-t cushion assembly 26 can be raised to provide access to -the i.nterior of the seat structure 30.
The arrangement of the offset hinges 29 and the three interconnected cushion support frame assemblies 18, 19 and 26 makes it possible to operate the folding bed chair completely from the extreme front end thereof, namely the seat structure 30 by moving the structure 30 toward and away from a position between the arms 10 of the device.
The three cushion support frame assemblies 18, 19 and 26 -thus will automatically move from the chair mode to the bed mode and return to chair mode without any manual contact -therewith excep-t the motion manually imparted the front end of the cushion support frame assembly 26.
It will ~occur to one skilled in the art that when the folding bed chair is in the chair mode, the cushion support frame assembly 18 rests against the socket member 16 preventing additional backward movement of -the cushion frame suppor-t assemblies 18 and 19 and thereby forming a 28 sturdy and resilient back for the chair bed.
A decorative panel ~1 is attached to -the front edge of the cushion suppor-t frame 26 so as to cover the opening created when the wedges ~0 elevate the cushion support frame assembly 26 as best seen in ~igure 1 of the drawings.
It will thus be seen that a new and useful folding bed chair has been illustrated and descri.bed and -that various changes and modifications may be made therein withou-t departing~from the spirit of -the invention and having thus described my invention, what I claim is:
