Abstract

Abstract A corner construction as used for furniture, display fixtures, and the like which comprises a corner connector of rigid, yet limitedly, compressible material of construction having a body with a plurality of arms; each arm extending from the body in axially perpendicular relationship to the adjacent arm. Each arm of said connector is of four sided tubular character with the sides recessed to develop co-extensive corner, ridge-forming elements each having a rounded outer edge. Each arm is lengthwise tapered from its body connected end to its outer free end in the order of approximately one degree. Tubular frame members of four sided cross-section being open at their ends receive the arms of said corner connector as by a snug, friction fit for integration into the intended article. The corner connector arms are so related to the body thereof that when in a horizontal disposition the corner ridge elements will be in diamond-forming relation as viewed in a vertical plane and thereby causing the engaged frame members to present one side thereof for supporting panels, shelves, table tops, and the like.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 171 words
A corner connector for developing a corner construction for furniture and the like comprising a body, a plurality of arms integral with said body and projecting therefrom in axially perpendicular relationship to the at least immediately proximate arm, each arm having a normally free end spacedly from said connector body, each arm tapering inwardly toward its free end so that the free end is of less cross-section than the opposite or body-adjacent end, each of said arms being of four-sided character and having projecting ridge-like elements at the intersection of adjacent sides, the axis of projection of said ridge-like elements being at an angle greater than 90° to the planes of the adjacent sides of the related arm, each of said ridge-like elements spacedly from the adjacent sides having an outer arcuate edge, said arms being presented with respect to said body whereby adjacent ridge-like elements are disposed within mutually perpendicular planes, and each arm being of tubular character having a substantially coextensive bore opening outwardly through the free end thereof.
Claim 2
Dependent Claim 171 words
A corner connector for developing a corner construction for furniture and the like comprising a body, a plurality of arms integral with said body and projecting therefrom in axially perpendicular relationship to the at least immediately proximate arm, each arm having a normally free end spacedly from said connector body, each arm tapering inwardly toward its free end so that the free end is of less cross-section than the opposite or body-adjacent end, each of said arms being of four-sided character and having projecting ridge-like elements at the intersection of adjacent sides, the axis of projection of said ridge-like elements being at an angle greater than 90° to the planes of the adjacent sides of the related arm, each of said ridge-like elements spacedly from the adjacent sides having an outer arcuate edge, said arms being presented with respect to said body whereby adjacent ridge-like elements are disposed within mutually perpendicular planes, and each arm being of tubular character having a substantially coextensive bore opening outwardly through the free end thereof.
Claim 3
Dependent Claim 20 words
A corner connector as defined in claim 1 and further characterized by the taper in each arm being approximately 1°.
Claim 4
Dependent Claim 27 words
A corner connector as defined in claim 2 and further characterized by said connector body and arms being unitarily fabricated from a rigid material having limited compressibility.
