Description
Background and Summary of the Invention
The present invention relates to a combination chair and bed for small children and includes a back, seat and footrest that are suitably attached to each other such that adjacent of these elements may rotate with respect to each other. A support rod having leg portions spaced apart from each other and an intermediate connecting portion is operatively connected to the back and footrest, and a locking rod is operatively connected to the support rod and to the back such that as the intermediate portion of the locking rod is moved between a plurality of locking positions along the back, the back, seat and footrest assume a variety of different positions, including a position wherein these elements are aligned with each other so as to define a bed, another position wherein these elements are folded or collapsed for storage or carrying, and several additional, intermediate positions wherein these elements are arranged at varying angles to each other to define a variety of sitting positions.

Description of the Preferred Embodiment
As illustrated in FIGS. 1 and 2, the combination chair and bed of the present invention consists of a back 10, seat 12, and footrest 14. Shafts 16 operatively connect the back 10, and the seat 12, permitting the back 10 and the seat 12 to rotate with respect to each other. In like manner, shafts 18 operatively connect the seat 12 and the footrest 14 permitting these elements to rotate with respect to each other.
The footrest 14 is provided on each side thereof with upstanding arms 20. A support rod designated generally by the reference numeral 22 in FIGS. 1 and 2 consists of two leg portions 24 that are spaced apart from each other and an intermediate connecting portion 26. As will be further apparent from FIG. 2, the shafts 28 operatively connect the ends of the legs 24 to the arms 20 of the footrest 14 permitting the footrest 14 to rotate relative to the leg portions 24. In similar manner, the shafts 30 operatively connect the leg portions 24 to the back 10 permitting the back 10 to rotate relative to the leg portions 24.
A locking rod designated generally by the reference numeral 32 consists of ends 34 and an intermediate portion 36. The ends 34 of the locking rod 32 are mounted within openings 37 provided within the leg portions 24 permitting the locking rod 32 to rotate relative to the support rod 22.
As seen in FIGS. 1 and 4, there are provided on the back 10 a plurality of pairs of locking flanges designated generally by the reference numeral 38. It will be apparent from FIG. 4 that near the top of the back 10 there is provided a first pair of locking flanges 38' while at the lower end of the back 10 there is provided a second pair of locking flanges 38". Intermediate the first and second flanges 38' and 38" are positioned a plurality of third pairs of locking flanges designated by the reference numeral 38'", the purpose of which will be explained in detail hereinafter. Finally, a guide rod 40 is suitably mounted to extend along the back 10.
A positioning and locking member designated generally by the reference numeral 42 in FIG. 6 is mounted to slide along the guide rod 40. The locking member 42 is provided with a slotted portion 44 through which the intermediate portion 36 of the locking rod 32 extends. It will be apparent that as the intermediate portion 36 is moved downwardly within the slotted portion 42 it is possible to move the locking member 42 and the intermediate portion 36 up and down the back 10 along the rod 40. When it is desired to lock the back 10 in a particular position, the intermediate portion 36 is moved upwardly within the slotted portion 42 until the intermediate portion 36 is positioned within the desired pair of locking flanges 38.
It will be apparent from FIG. 3 that when the intermediate portion 36 of the locking rod 32 is positioned within the first pair of locking flanges 38', the back 10, seat 12 and footrest 14 assume a rectilinear position forming a bed. When the intermediate portion 36 of the locking rod 32 is positioned within the second pair of locking flanges 38", as illustrated in solid lines in FIG. 5, the seat 12 and footrest 14 rotate into a folded position. In this position, the combination chair and bed is in collapsed position and may be carried, for example, by the intermediate connecting portion 26 of the support rod 22 or stored for use at a later date. It will also be apparent that as the intermediate portion 36 of the locking rod 32 is positioned within one of the remaining third pairs of locking flanges 38'", as illustrated in FIGS. 1-2, the seat 12 and footrest 14 are rotated to occupy different angular relationships and thus define different sitting positions. In these various sitting positions the intermediate portion 26 of the support rod 22 rests against the ground or other surface supporting the combination chair and bed.
