Convertible sofa-chair

Claim 2

In a convertible sofa, chair or the like, the combination comprising a pair of generally hollow bases disposed in spaced relation to each other, platform means overlying both of said bases to define a sleeping bed, one of said bases being smaller than the other of said bases permitting a telescoping arrangement therebetween whereby the sleeping bed may be converted into a sitting chair, hinge means pivoting parts of said platform means into a back rest for the sitting chair when the bases are telescoped together, and spaced slanted elements carried by one part of said platform means and straddling the smaller one of said bases when the bases are extended from each other, said spaced slanted elements engaging the other of said bases when the bases are telescoped together so that the one part of said platform means defines a slanted seating surface.

Claim 3

The invention as recited in claim 1 wherein the pivoted parts of said platform means are disposed in an inverted V-shaped configuration.

Claim 4

The invention as recited in claim 1 wherein said platform means includes three parts interconnected by said hinge means.

Claim 5

The invention as recited in claim 3 wherein said hinge means comprises a pair of hinges, one of which is connected to said one of said bases.

Claim 6

The invention as recited in claim 4 wherein said back rest is formed by two parts of said platform means with the other of said hinges therebetween.

Claim 7

In a convertible sofa, chair or the like, the combination comprising a generally fixed base having a pair of spaced side members and a rear member joining rear end portions of said side members, a generally movable base having a pair of spaced side walls, a rear wall joining rear end portions of said side walls, a front wall joining front end portions of said side walls, a bottom wall extending between said side, front and rear walls to form a storage box, and roller means on said base to facilitate movement thereof, a three piece flat platform supported on top of said fixed and movable bases, a first hinge connecting first and second pieces of said platform and a second hinge connecting second and third pieces of said platform, said first hinge also being connected to said rear wall of the movable base whereby movement of said movable base against said fixed base causes said second piece to pivot relative to said first and third pieces, said side members of said fixed base being spaced a greater distance that said side walls of said movable base whereby said movable base may nest in said fixed base, and spaced slanted elements formed on the undersurface of said first piece of said platform and being in contact with top edges of said spaced side members of the fixed base whereby said first piece presents a slanted seating surface and whereby the assembly is frictionally locked in its sitting chair condition.

Claim 8

In a convertible sofa, chair or the like, the combination comprising a generally fixed base having a pair of spaced side members and a rear member joining rear end portions of said side members, a generally movable base having a pair of spaced side walls, a rear wall joining rear end portions of said side walls, a front wall joining front end portions of said side walls, a bottom wall extending between said side, front and rear walls to form a storage box, and roller means on said base to facilitate movement thereof, a three piece flat platform supported on top of said fixed and movable bases, a first hinge connecting first and second pieces of said platform and a second hinge connecting second and third pieces of said platform, said first hinge also being connected to said rear wall of the movable base whereby movement of said movable base against said fixed base causes said second piece to pivot relative to said first and third pieces, said side members of said fixed base being spaced a greater distance that said side walls of said movable base whereby said movable base may nest in said fixed base, and spaced slanted elements formed on the undersurface of said first piece of said platform and being in contact with top edges of said spaced side members of the fixed base whereby said first piece presents a slanted seating surface and whereby the assembly is frictionally locked in its sitting chair condition.

Claim 9

The invention as recited in claim 6 wherein the three pieces of said platform are of equal thickness, and wherein the fixed and movable bases are of equal heights.
