Abstract

A divan is configurable between upright and table configurations. The divan includes linkages which enable rotation of a backrest from the upright configuration to the table configuration. The divan includes a seat pan which is joined in the upright configuration and split in the table configuration. Joining the seat pan in the upright configuration provides a seating region with extra length. Splitting the seat pan in the table configuration provides two seating regions, one on each side of the table.

First claim

What is claimed:

1 . A divan comprising:
a fixed assembly, the fixed assembly comprising:
a pair of fixed base frames; and
a fixed seat pan cushion; wherein the fixed seat pan cushion extends between and couples the pair of fixed base frames;
a trackable assembly, the trackable assembly comprising:
a pair of trackable base frames;
a trackable seat pan cushion; wherein the trackable seat pan cushion extends between and couples the pair of trackable base frames; and
a pair of trackable armrests; wherein the pair of trackable armrests are coupled to the pair of trackable base frames;
a backrest assembly, the backrest assembly comprising:
a seat back cushion; and
a table top; wherein the seat back cushion and the table top are disposed on opposing faces of the backrest assembly; and
a pair of rotatable linkages; wherein the fixed assembly, the trackable assembly, the backrest assembly, and the pair of rotatable linkages form a pair of four-bar linkages; wherein the divan is configurable between an upright configuration and a table configuration.

2 . The divan of claim 1 , comprising a pair of floor tracks; wherein the pair of floor tracks are aligned in parallel; wherein the pair of fixed base frame and the pair of trackable base frames are coupled to the pair of floor tracks; wherein the trackable assembly tracks along the pair of floor tracks causing the divan to be configured between the upright configuration and the table configuration; wherein the fixed assembly is fixed to the pair of floor tracks as the trackable assembly tracks along the pair of floor tracks.

3 . The divan of claim 1 , the fixed assembly comprising a fixed backrest frame; wherein the fixed backrest frame extends between and couples the pair of fixed base frames; wherein the backrest assembly covers the fixed backrest frame when the divan is in the upright configuration; wherein the backrest assembly does not cover the fixed backrest frame when the divan is in the table configuration.

4 . The divan of claim 1 , wherein the pair of fixed base frames each comprise a pair of fixed vertical portions and a fixed horizontal portion; wherein the fixed horizontal portion extends between the pair of fixed vertical portions.

5 . The divan of claim 4 , wherein the pair of fixed base frames each comprise a stopper portion; wherein the stopper portion extends from the fixed horizontal portion; wherein the pair of rotatable linkages abut the stopper portion of each of the pair of fixed base frames when the divan is in the table configuration.

6 . The divan of claim 1 , wherein the pair of trackable base frames abut the pair of fixed base frames when the divan is in the upright configuration.

7 . The divan of claim 1 , wherein the pair of trackable base frames each comprise:
a trackable vertical portion; a trackable horizontal portion; wherein the trackable horizontal portion extends from the trackable vertical portion; and a trackable linkage portion; wherein the trackable linkage portion extends from the trackable horizontal portion; wherein the trackable linkage portion of each of the pair of trackable base frames are disposed above the pair of fixed base frames when the divan is in the upright configuration.

8 . The divan of claim 7 , wherein the pair of trackable armrests enclose the trackable linkage portion of each of the pair of trackable base frames and the pair of rotatable linkages.

9 . The divan of claim 1 , wherein the fixed seat pan cushion and the trackable seat pan cushion provide a joint seat pan when the divan is in the upright configuration; wherein the fixed seat pan cushion and the trackable seat pan cushion are separated by the backrest assembly when the divan is in the table configuration.

10 . The divan of claim 9 , wherein the fixed seat pan cushion and the trackable seat pan cushion abut and are flush to provide the joint seat pan when the divan is in the upright configuration.

11 . The divan of claim 1 , comprising:
a first pair of revolute joints; wherein the pair of fixed base frames and the pair of rotatable linkages are coupled by the first pair of revolute joints; a second pair of revolute joints; wherein the backrest assembly and the pair of rotatable linkages are coupled by the second pair of revolute joints; and a third pair of revolute joints; wherein the trackable assembly and the backrest assembly are coupled by the third pair of revolute joints; wherein the fixed assembly, the trackable assembly, the backrest assembly, and the pair of rotatable linkages form the pair of four-bar linkages through rotation about the first pair of revolute joints, the second pair of revolute joints, and the third pair of revolute joints in combination with tracking of the trackable assembly.

12 . The divan of claim 1 , wherein the pair of fixed base frames are disposed between the pair of rotatable linkages.

13 . The divan of claim 1 , wherein the pair of rotatable linkages comprise a boomerang shape.

14 . The divan of claim 1 , wherein the backrest assembly is disposed at a seatback angle when the divan is in the upright configuration; wherein the backrest assembly is disposed at a table angle when the divan is in the table configuration.

15 . The divan of claim 1 , wherein the fixed assembly, the trackable assembly, and the backrest assembly jointly provide a seating region when the divan is in the table configuration; wherein the fixed assembly and the trackable assembly separately provide seating regions when the divan is in the table configuration.
