Abstract

Abstract An adjustable piece of furniture comprising three basic structural components adapted to be joined to each other for providing the basic frame structure of the piece of furniture. The three basic components are as follows: (a) an elbow-joint, (b) a T-joint and (c) a piece of tubing. The piece of furniture comprises two U-shaped components arranged parallel to each other which are joined by means of three pieces of tubing, two of said pieces of tubing joining respectively the ends of the legs of the U-shaped components to each other, whereas the third piece of tubing joins the base members of the two U-shaped components to each other substantially at their midpoints. The legs of each one of the U-shaped components are joined to the base member by elbows. The base member, in turn, comprises a T-joint at substantially its midpoint which is joined to the elbows at opposite ends of the base member by pieces of tubing of suitable length. The T-joint in each base member has a leg extending therefrom which is joined to the leg of the other T-joint by means of a piece of tubing. The piece of tubing joining the legs of the T-joints in each base member of the U-shaped components serves as a support for a flexible supporting surface, whereas one of the pieces of tubings joining opposite ends of legs of the U-shaped components serves as the other support for the flexible support member.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 198 words
A piece of furniture adapted to be converted to one of different size, comprising in combination the following components: pair of parallelly disposed U-shaped members, each one of said U-shaped members comprising a pair of parallel legs and a base, said parallel legs being joined to said base by means of first pairs of elbow-joints, said base including a T-joint having a pair of arms and a leg portion projecting from said base, first pairs of pieces of tubing respectively joining said pair of arms of said T-joint to said first pairs of elbow-joints, second and third pairs of elbow-joints respectively mounted on the ends of said pairs of parallel legs distant from said base, second pieces of tubing joining respectively said second and third pairs of elbow-joints, and a third piece of tubing joining said projecting leg portions of said T-joints in said bases of said pair of parallelly disposed U-shaped members, all of said components are at least partially tubularly-shaped, all of said tubularly shaped portions having equal outside and inside diameters, whereby the opposite and parallel components of the piece of furniture of equal length can be replaced by components of a different equal length.
Claim 2
Dependent Claim 198 words
A piece of furniture adapted to be converted to one of different size, comprising in combination the following components: pair of parallelly disposed U-shaped members, each one of said U-shaped members comprising a pair of parallel legs and a base, said parallel legs being joined to said base by means of first pairs of elbow-joints, said base including a T-joint having a pair of arms and a leg portion projecting from said base, first pairs of pieces of tubing respectively joining said pair of arms of said T-joint to said first pairs of elbow-joints, second and third pairs of elbow-joints respectively mounted on the ends of said pairs of parallel legs distant from said base, second pieces of tubing joining respectively said second and third pairs of elbow-joints, and a third piece of tubing joining said projecting leg portions of said T-joints in said bases of said pair of parallelly disposed U-shaped members, all of said components are at least partially tubularly-shaped, all of said tubularly shaped portions having equal outside and inside diameters, whereby the opposite and parallel components of the piece of furniture of equal length can be replaced by components of a different equal length.
Claim 3
Dependent Claim 20 words
The piece of furniture, as set forth in claim 1, wherein all of said components are made of plastic material.
Claim 4
Dependent Claim 26 words
The piece of furniture, as set forth in claim 2, wherein said plastic material is selected from the group of acrylonitrile, butadiene, and styrene thermoplastic polymers.
Claim 5
Dependent Claim 56 words
The piece of furniture, as set forth in claim 1, wherein said elbow-joints and T-joints have sleeve portions projecting from their respective ends which are integral with the respective joints and are adapted to be inserted into said pieces of tubing so as to form a structural connection between said joints and said pieces of tubing.
Claim 6
Dependent Claim 37 words
The piece of furniture, as set forth in claim 1, including a flexible sheet being connected to one of said second pieces of tubing and said third piece of tubing so as to form a seat therebetween.
Claim 7
Dependent Claim 133 words
The piece of furniture, as set forth in claim 1, wherein the piece of furniture is a chair, the pair of parallely disposed U-shaped members are disposed in confronting relationship in spaced parallel planes, each one of said U-shaped members comprises parallel upper and lower legs and a vertically extending base, said first pairs of pieces of tubing respectively joining said pair of arms of said T-joint to said first pairs of elbow-joints are vertically aligned, one of said second pieces of tubing joining said second and third pair of elbow-joints is disposed above the other, the third piece of tubing is disposed horizontal, and comprising a flexible sheet connected to the upper one of said second pieces of tubing and said third piece of tubing so as to form a seat therebetween.
Claim 8
Dependent Claim 54 words
A chair, as set forth in claim 6, wherein the pieces of tubing in the first pairs thereof are of at least substantially equal lengths, and wherein the flexible sheet is connected to only the upper one of said second pieces of tubing and said third piece of tubing so as to festoon therefrom.
