Abstract
Abstract Thin, flat multi-sided plates in various polygonal shapes are provided with a resilient, upstanding annular flange on one or both of their faces to receive the ends of tubular elements, such as beverage cans. Upstanding pins are formed on one face of the plates, near one end of certain of their sides, and laterally-extending tabs having pin-engaging apertures are hingedly attached to the plates by means of thin, flexible webs formed at the opposite ends of the same sides. Preferably, the webs are designed to displace the tabs in the direction of the pin-carrying face so that adjacent plates are in substantial alignment when their corresponding tabs and pins are interlocked.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
180 words
A connector for use in a construction embodying a plurality of tubular elements fastened together by means of a plurality of such connectors, said connector comprising: a substantially planar base plate having a peripheral polygonal edge defining a plurality of adjoining sides; a single attachment member hingedly mounted to, and extending laterally outwardly of certain of said sides, adjacent the corresponding end of each of said certain sides, said attachment member comprising a substantially planar tab having an aperture therein; connecting means formed on said base plate adjacent the opposite ends of said certain sides, for releasably engaging corresponding attachment members on adjacent ones of said connectors, said connecting means comprising upstanding pins formed on at least one face of said plate in registry with the apertures in said corresponding tabs on adjacent connectors, for insertion into said apertures in releasable frictional engagement therewith; and a resilient upstanding flange on at least one face of said plate, said flange having an inner wall conforming to and adapted to receive and frictionally retain the end of one of said tubular elements.
Claim 2
Dependent Claim
180 words
A connector for use in a construction embodying a plurality of tubular elements fastened together by means of a plurality of such connectors, said connector comprising: a substantially planar base plate having a peripheral polygonal edge defining a plurality of adjoining sides; a single attachment member hingedly mounted to, and extending laterally outwardly of certain of said sides, adjacent the corresponding end of each of said certain sides, said attachment member comprising a substantially planar tab having an aperture therein; connecting means formed on said base plate adjacent the opposite ends of said certain sides, for releasably engaging corresponding attachment members on adjacent ones of said connectors, said connecting means comprising upstanding pins formed on at least one face of said plate in registry with the apertures in said corresponding tabs on adjacent connectors, for insertion into said apertures in releasable frictional engagement therewith; and a resilient upstanding flange on at least one face of said plate, said flange having an inner wall conforming to and adapted to receive and frictionally retain the end of one of said tubular elements.
Claim 3
Dependent Claim
48 words
The connector defined by claim 1, wherein said tabs include a flexible resilient transverse hinge portion of reduced thickness, formed integrally with the edge of said base plate, for rotation of said tabs through an arc in excess of 180° relative to the plane of said base plate.
Claim 4
Dependent Claim
46 words
The connector defined by claim 2, wherein said tabs are formed to be normally in alignment with said one face of said base plate, whereby the corresponding faces of the base plates of adjacent connectors are substantially co-planar when said tabs and pins are in engagement.
Claim 5
Dependent Claim
27 words
The connector defined by claim 3 further comprising retaining means on said flange, for frictionally retaining the end of a tubular element having a bead formed thereon.
Claim 6
Dependent Claim
39 words
The connector defined by claim 4, wherein said retaining means comprises a groove formed in the inner wall of said flange, for releasably engaging the said bead upon insertion of the end of said tubular element into said flange.
Claim 7
Dependent Claim
18 words
The connector defined by claim 3, having such resilient, upstanding flanges on both faces of said base plate.
Claim 8
Dependent Claim
15 words
The connector defined by claim 3, wherein said base plate is generally rectangular in plan.
Claim 9
Dependent Claim
23 words
A construction for use in assembling a plurality of tubular elements, comprising in combination a plurality of connectors as defined by claim 7.
Claim 10
Dependent Claim
15 words
The connector defined by claim 3, wherein said base plate is generally triangular in plan.
Claim 11
Dependent Claim
23 words
A construction for use in assembling a plurality of tubular elements, comprising in combination a plurality of connectors as defined by claim 9.
Claim 12
Dependent Claim
15 words
The connector defined by claim 3, wherein said base plate is generally trapezoidal in plan.
Claim 13
Dependent Claim
23 words
A construction for use in assembling a plurality of tubular elements, comprising in combination a plurality of connectors as defined by claim 11.
Claim 14
Dependent Claim
21 words
In combination, the connector defined by claim 3, with at least one of said tubular elements mounted to said flange thereon.
Claim 15
Dependent Claim
23 words
A construction for use in assembling a plurality of tubular elements, comprising in combination a plurality of connectors as defined by claim 3.
Claim 16
Dependent Claim
18 words
The construction defined by claim 14, further comprising a plurality of such tubular elements mounted to said connectors.
