Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
121 words
A connecting element for use in assembling furniture, shelves and the like comprising an elongated tubular body of square section including a pair of exposable walls and further having oppositely disposed closed end walls and at least three equally spaced opposed pairs of right angularly extending tubular jointing means of square section each of said jointing means projecting outwardly from said elongated tubular body from zones spaced inwardly of said end wall and further spaced inwardly from at least one of said exposable walls, said jointing means serving to support plurally perforated planar elements arranged to receive said outwardly projecting jointing means and further including oppositely disposed walls and additional frustum-shaped support means which lie in planes coplanar with said walls.
Claim 2
Dependent Claim
121 words
A connecting element for use in assembling furniture, shelves and the like comprising an elongated tubular body of square section including a pair of exposable walls and further having oppositely disposed closed end walls and at least three equally spaced opposed pairs of right angularly extending tubular jointing means of square section each of said jointing means projecting outwardly from said elongated tubular body from zones spaced inwardly of said end wall and further spaced inwardly from at least one of said exposable walls, said jointing means serving to support plurally perforated planar elements arranged to receive said outwardly projecting jointing means and further including oppositely disposed walls and additional frustum-shaped support means which lie in planes coplanar with said walls.
Claim 3
Dependent Claim
41 words
A connecting element as claimed in claim 1, wherein the support means are joined to and reinforced by transverse ribs disposed therebetween, at least some of said ribs and said support means being joined in substantially an I shape in section.
Claim 4
Dependent Claim
40 words
A connecting element as claimed in claim 1, wherein said oppositely disposed walls diverge toward an outward extremity thereof such that an opening defined by said walls is greater at an outward extremity thereof than at an inward extremity thereof.
Claim 5
Dependent Claim
75 words
A connecting element as claimed in claim 2, wherein the ribs, support means and jointing means cooperate with complementally shaped channels in a panel with opposed planar side walls so as to join said panel to the connecting element such that the opposed planar side walls of said panel lie in coplanar relation with the respective sides of the connecting element, whereby a flush surface is achieved between an adjoining element and an adjoining panel.
