Abstract
Abstract The invention relates to an assembly of elements which can be readily placed together to form differing types of furniture. Equally, such furniture may be dismantled and the type of furniture changed, for instance the form may be a chair or a table or a table top with a shelf, etc. It consists of generally two rigid supports between which is placed a rigid element, such rigid element being engaged by means of tongues and slots, and the whole structure being rigidly held together by interconnecting elements adapted to tighten the supports towards each other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
220 words
A piece of furniture, comprising: at least two rigid supports, each including corresponding fastening apertures spaced at corresponding locations on said at least two rigid supports and guide apertures located adjacent the edges of said at least two rigid supports; at least one rigid element of predetermined length extending between said rigid supports and including projections received in said guide apertures, said guide apertures serving to locate said at least one rigid element in the assembly of the piece of furniture; at least three parallel rigid strut members of said predetermined length in abutting relationship between said rigid supports, each strut member including fastening elements in the ends thereof; and fastening means extending through said fastening apertures and engaging said fastening elements to draw said supports in firm abutting relationship with the ends of said rigid strut members thereby forming a self-supporting rigid unit standing on said supports, said fastening apertures including at least two sets of at least three holes respectively located at upper, lower and Intermediate portions of said at least two rigid supports, and said guide apertures being elongated, said at least three holes of each set being in vertical alignment and said guide apertures being aligned vertically and horizontally along their longitudinal axis, said vertically aligned apertures being spaced approximately intermediate between said spaced fastening apertures.
Claim 2
Dependent Claim
220 words
A piece of furniture, comprising: at least two rigid supports, each including corresponding fastening apertures spaced at corresponding locations on said at least two rigid supports and guide apertures located adjacent the edges of said at least two rigid supports; at least one rigid element of predetermined length extending between said rigid supports and including projections received in said guide apertures, said guide apertures serving to locate said at least one rigid element in the assembly of the piece of furniture; at least three parallel rigid strut members of said predetermined length in abutting relationship between said rigid supports, each strut member including fastening elements in the ends thereof; and fastening means extending through said fastening apertures and engaging said fastening elements to draw said supports in firm abutting relationship with the ends of said rigid strut members thereby forming a self-supporting rigid unit standing on said supports, said fastening apertures including at least two sets of at least three holes respectively located at upper, lower and Intermediate portions of said at least two rigid supports, and said guide apertures being elongated, said at least three holes of each set being in vertical alignment and said guide apertures being aligned vertically and horizontally along their longitudinal axis, said vertically aligned apertures being spaced approximately intermediate between said spaced fastening apertures.
Claim 3
Dependent Claim
67 words
A piece of furniture as in claim 1 wherein said fastening elements are threaded holes and said fastening means each include a threaded member engaging a respective threaded hole and each fastening means having a manually rotatable knob and being operable to draw said at least two rigid supports toward each other into secure abutting relationship with the ends of said strut members and said rigid element.
Claim 4
Dependent Claim
47 words
A piece of furniture as in claim 2 further comprising resilient washerlike elements sandwiched between the ends of said strut members, an inner surface of said knob and respective inner and outer surfaces of an associated support, said resilient washerlike elements aiding in locking said fastening means.
Claim 5
Dependent Claim
32 words
A piece of furniture as in claim 3 wherein each of said knobs includes an extending shoulder forming said inner surface at its exposed end for engagement with a said washerlike element.
