Abstract
Abstract A generally L-shaped element, a plurality of which can be assembled to form a table, chair, sofa, or like article of furniture. Uniformly positioned holes in each element and rods which extend through the holes to retain the elements in a unitary assembly. L-shaped elements so formed that they can be assembled in numerous different configurations. An article of furniture that can be disassembled for transport.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
198 words
An article of manufacture comprising a generally L-shaped member formed by a horizontal plate and a vertical plate, each said plate having an inner end and an outer end and being rigidly joined at respective inner ends in generally perpendicular relation, said horizontal plate having upper and lower surfaces that are symmetrical of a plane centrally of said horizontal leg, said horizontal leg having opposed parallel edge faces generally normal to and extending between said surfaces so that plural said horizontal legs can be placed in juxtaposition to form a substantially continuous surface, there being at least two openings through said horizontal plate, said openings being symmetrical of the mid-region of said horizontal leg and elongate along a central axis lying in said central plane and terminating in said faces so that a plurality of said members can be fastened together to form an article of furniture by aligning the openings in said horizontal plate of each said member, irrespective of whether the vertical legs extend upward or downward and whether the inner end of the horizontal plate of one said member is aligned with the inner or outer end of the horizontal plate of the adjacent member.
Claim 2
Dependent Claim
198 words
An article of manufacture comprising a generally L-shaped member formed by a horizontal plate and a vertical plate, each said plate having an inner end and an outer end and being rigidly joined at respective inner ends in generally perpendicular relation, said horizontal plate having upper and lower surfaces that are symmetrical of a plane centrally of said horizontal leg, said horizontal leg having opposed parallel edge faces generally normal to and extending between said surfaces so that plural said horizontal legs can be placed in juxtaposition to form a substantially continuous surface, there being at least two openings through said horizontal plate, said openings being symmetrical of the mid-region of said horizontal leg and elongate along a central axis lying in said central plane and terminating in said faces so that a plurality of said members can be fastened together to form an article of furniture by aligning the openings in said horizontal plate of each said member, irrespective of whether the vertical legs extend upward or downward and whether the inner end of the horizontal plate of one said member is aligned with the inner or outer end of the horizontal plate of the adjacent member.
Claim 3
Dependent Claim
36 words
The article defined by claim 1 wherein said vertical leg includes at least one opening therethrough, said opening being elongate along an axis parallel to the axis of elongation of the openings in said horizontal leg.
Claim 4
Dependent Claim
37 words
The article defined by claim 1 wherein said vertical leg is curved so that the outer end thereof extends beyond the inner end thereof in a direction parallel to the plane of Symmetry of said horizontal leg.
Claim 5
Dependent Claim
81 words
The article defined by claim 1 in combination with a plurality of identical said members, there being at least three said members oriented such that the vertical plates extend downward, all said members being aligned in lateral juxtaposition so that said openings align with one another, and tension elements extending through said aligned openings for retaining said members in assembled condition, thereby forming an article of furniture in which said downward extending members constitute the legs of said article of furniture.
Claim 6
Dependent Claim
134 words
The article defined by claim 4 wherein the vertical legs of said member are formed with at least two spaced apart openings therethrough in combination with first and second generally L-shaped elements each having a vertical plate and a horizontal plate rigidly attached to said vertical plate, the vertical plate of said element being formed with openings therethrough that are positioned so that the horizontal plates of said element are parallelly spaced above the horizontal plates of said generally L-shaped members when last said openings register with the openings in said vertical plate of said generally L-shaped members, and means extending through the registered openings for retaining the vertical legs of said elements to the vertical legs of said generally L-shaped members so that the horizontal plates of said L-shaped elements form arm rests.
Claim 7
Dependent Claim
272 words
An article of furniture comprising in combination a plurality of identical generally L-shaped members each of which is formed by a horizontal plate and a vertical plate, each said plate having an inner end and an outer end and being rigidly joined at respective inner ends in generally perpendicular relation, said horizontal plate having upper and lower surfaces that are symmetrical of a plane centrally of said horizontal leg, said horizontal leg having opposed parallel edge faces generally normal to and extending between said surfaces, there being at least two openings through said horizontal plate, said openings being symmetrical of the mid-region of said horizontal leg and elongate along a central axis lying in said central plane and terminating in said faces, a first pair of said L-shaped members being oriented with respective horizontal plates juxtaposed so that the respective vertical plates depend from opposite ends of the first juxtaposed pair to define one pair of legs for the article of furniture, a second pair of said L-shaped members being oriented with respective horizontal plates juxtaposed so that the respective vertical plates depend from opposite ends of the second juxtaposed pair to define another pair of legs for the article of furniture, the remainder of said plurality of said L-shaped members disposed between said first and second pairs, said remainder of L-shaped members being oriented with the horizontal plates thereof in juxtaposition to the horizontal plates of said first and second pair, the vertical plates of said remainder extending upward to define the back of the article of furniture, and means extending through said openings for retaining said members in juxtaposed assembly.
Claim 8
Dependent Claim
272 words
An article of furniture comprising in combination a plurality of identical generally L-shaped members each of which is formed by a horizontal plate and a vertical plate, each said plate having an inner end and an outer end and being rigidly joined at respective inner ends in generally perpendicular relation, said horizontal plate having upper and lower surfaces that are symmetrical of a plane centrally of said horizontal leg, said horizontal leg having opposed parallel edge faces generally normal to and extending between said surfaces, there being at least two openings through said horizontal plate, said openings being symmetrical of the mid-region of said horizontal leg and elongate along a central axis lying in said central plane and terminating in said faces, a first pair of said L-shaped members being oriented with respective horizontal plates juxtaposed so that the respective vertical plates depend from opposite ends of the first juxtaposed pair to define one pair of legs for the article of furniture, a second pair of said L-shaped members being oriented with respective horizontal plates juxtaposed so that the respective vertical plates depend from opposite ends of the second juxtaposed pair to define another pair of legs for the article of furniture, the remainder of said plurality of said L-shaped members disposed between said first and second pairs, said remainder of L-shaped members being oriented with the horizontal plates thereof in juxtaposition to the horizontal plates of said first and second pair, the vertical plates of said remainder extending upward to define the back of the article of furniture, and means extending through said openings for retaining said members in juxtaposed assembly.
