Abstract

A piece of furniture comprises a chassis having a plurality of hinge connections to which a bed structure is connected. The bed structure comprises four parts which are hinged to each other including a back with headrest part, a seat and a two part leg support. The back and one part of the leg support are hingedly connected to the chassis through additional articulated linkages. The piece of furniture is convertible from a bed configuration with all parts of the bed structure aligned with each other, to an easy chair configuration, by the application of selected amounts of load on the parts of the bed structure by a person lying on the structure.

Claims

1. A piece of furniture comprising:

a chassis (1) having first, second and third spaced apart contact portions;

a first arm (19) pivotally mounted to said first contact portion at a first hinge (5);

a second arm (8) having one end pivotally mounted to said third contact portion at a second hinge (9), said second arm having an opposite end;

a upper-structure connected at a plurality of hinges to said first and second arms and to said second contact portion, said upper-structure comprising a back support (14) having opposite ends, said back support having a T-shaped elevation with a cross piece for supporting a mattress and a post rigidly connected to said cross piece, said post of said back support being pivotally connected directly to said opposite end of second arm at a third hinge (7) located intermediate said opposite ends of said back support, and said back support being connected to said chassis only by said third hinge, a seat (13) having one end connected only at a fourth hinge (18) to one end of said back support, said seat having an opposite end, a first leg support (12) having one end connected only at a fifth hinge (17) to said opposite end of said seat, said first leg support having an opposite end and having a T-shaped elevation with a cross piece for supporting a mattress and a post rigidly connected to said cross piece of said first leg support, said post of said first leg support being directly pivotally connected at a sixth hinge (6) to said second contact portion and at an intermediate location on said first leg support between said one end and said opposite end of said first leg support, said seat being connected only to said back support and said first leg support, and a second leg support (11) having one end pivotally connected at a seventh hinge to said opposite end of said first leg support, said second leg support having an opposite end and being pivotally connected to said first arm at an eighth hinge (10) and at a location intermediate said one end and said opposite end of said second leg support; and

at least some of said hinges being lockable for locking a relative position between said first and second arms and between said back support, said seat, and said first and second leg supports;

said back support, said seat, and said first and second leg supports each comprising a frame defining a concave space for receiving a single mattress spanning said back support, said seat, and said first and second leg supports, each of said fourth, fifth and seventh hinges being connected at upper edges of said frames forming said respective back support, seat and first and second leg supports.

2. A piece of furniture according to claim 1 wherein said first contact portion is relatively tall compared to said third contact portion and said second contact portion is of intermediate height with respect to said first and second contact portions.
