Abstract
Abstract A furniture construction kit comprising a few standard parts makes it possible to construct a variety of articles of furniture. The main parts are elongated frame elements each consisting of two coaxial tubes interconnected by diametrically opposed radial ribs, the inner tube having an internal thread at one end, and a joint associable with the end threads of the frame elements. The joint comprises two like rings fitting between the ends of two associated frame elements and a connecting member having a threaded shank for connection with the internal end thread for coaxial association the associated frame element and a sectorshaped hook head extending eccentrically from the shank in a plane perpendicular to the shank axis into one of the rings.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
291 words
A furniture construction kit comprising 1. at least two like elongated annular frame elements, each of the elements having an end and comprised of a. an outer cylindrical tube and an inner cylindrical tube coaxial therewith, b. the inner cylindrical tube having an internal thread at the end, and c. axially continuous, diametrically opposed radial ribs interconnecting the cylindrical tubes, adjacent ones of the radial ribs defining axially extending spaces between the two cylindrical tubes and 2. a joint associable with the threads at the ends of the frame elements, the joint comprising a. a ring means fitting between the ends of two of the frame elements, the ring means being comprised of an outer cylindrical tube and an inner cylindrical tube coaxial therewith, the inner tube of the ring means defining a central bore, axially continuous, diametrically opposed radial ribs interconnecting the cylindrical tubes of the ring means, adjacent ones of the radial ribs defining axially extending spaces, b. a connecting pin having an externally threaded end for threaded connection with the internal thread at the end of one of the frame elements, the connecting pin fitting into the central bore of the ring means and being coaxially associable with the one frame element, and c. a connecting member having an externally threaded shank for threaded connection with the internal thread at the end of the other one of the frame elements, the threaded shank being coaxially associable with the other frame element, the connecting member having a sector-shaped hook head extending eccentrically from the shank in a plane perpendicular to the shank axis for engagement in a selected one of the axially extending spaces in the ring means, the selected space having an aperture for receiving the hook head.
Claim 2
Dependent Claim
291 words
A furniture construction kit comprising 1. at least two like elongated annular frame elements, each of the elements having an end and comprised of a. an outer cylindrical tube and an inner cylindrical tube coaxial therewith, b. the inner cylindrical tube having an internal thread at the end, and c. axially continuous, diametrically opposed radial ribs interconnecting the cylindrical tubes, adjacent ones of the radial ribs defining axially extending spaces between the two cylindrical tubes and 2. a joint associable with the threads at the ends of the frame elements, the joint comprising a. a ring means fitting between the ends of two of the frame elements, the ring means being comprised of an outer cylindrical tube and an inner cylindrical tube coaxial therewith, the inner tube of the ring means defining a central bore, axially continuous, diametrically opposed radial ribs interconnecting the cylindrical tubes of the ring means, adjacent ones of the radial ribs defining axially extending spaces, b. a connecting pin having an externally threaded end for threaded connection with the internal thread at the end of one of the frame elements, the connecting pin fitting into the central bore of the ring means and being coaxially associable with the one frame element, and c. a connecting member having an externally threaded shank for threaded connection with the internal thread at the end of the other one of the frame elements, the threaded shank being coaxially associable with the other frame element, the connecting member having a sector-shaped hook head extending eccentrically from the shank in a plane perpendicular to the shank axis for engagement in a selected one of the axially extending spaces in the ring means, the selected space having an aperture for receiving the hook head.
Claim 3
Dependent Claim
56 words
The furniture construction kit of claim 1, wherein the ring means consists of two like rings for coaxial association with the one frame element, each ring having an axial length equal to the outer radius of the elements, and an annular closure recessed from one end of one ring and closing one end of the spaces.
Claim 4
Dependent Claim
42 words
The furniture construction kit of claim 2, wherein the connecting pin is in fluted engagement with the central bore of the ring means over at least a portion thereof and has an internally threaded and opposite to be externally threaded end thereof.
Claim 5
Dependent Claim
57 words
The furniture kit of claim 2, wherein the connecting pin is in fluted engagement with the central bore of one of the rings of the ring means while the central bore of the other ring is in smooth engagement with the adjacent periphery of the connecting pin to permit rotation between the pin and the other ring.
Claim 6
Dependent Claim
46 words
The furniture construction kit of claim 3, further comprising an end plug having a threaded shank for threaded engagement with the internal thread at the other pin end, and an annular flange for engagement in an annular recess produced by the end closure of the ring.
Claim 7
Dependent Claim
44 words
The furniture construction kit of claim 2, wherein the outer cylindrical tube of at least one of the frame elements defines an axially extending elongated slot, and further comprising a panel adapted to be received in the slot for attachment to the frame element.
Claim 8
Dependent Claim
88 words
The furniture construction kit of claim 6, further comprising a connecting pin having two ends, an external thread at one pin end for threaded engagement with the internal thread of the one frame element and at least a portion of the non-threaded periphery of the pin being smooth whereby at least one of the rings may be rotated on the pin, and a hook for supporting the panel on the rotatable ring whereby the pin and rotatable ring constitute a hinge for the panel operating as a door.
Claim 9
Dependent Claim
57 words
The furniture construction kit of claim 1, further comprising a shaped washer for closing the end of the other frame element, the radial ribs being undercut at the end to provide a seat for the washer, and the washer having a knurled arcuate portion for frictional coupling with an associated arcuate peripheral portion of the ring means.
