Corner Element with Tang Fixation

A connector element, comprising:

• a body portion having a substantially planar first abutment surface, a substantially planar second abutment surface, and a corner surface, wherein said first abutment surface extends substantially perpendicularly from a first terminating edge of said corner surface, wherein said second abutment surface extends substantially perpendicularly from a second terminating edge of said corner surface, wherein said corner surface extends between a terminating edge of said first abutment surface to a terminating edge of said second abutment surface to define a curved surface, wherein said first abutment surface and said second abutment surface are formed at substantially 90° relative to one another, wherein an upper portion of said first abutment surface terminates at a substantially planar upper corner element surface and a lower portion of said first abutment surface terminates at a substantially planar lower corner element surface, and wherein an upper portion of said second abutment surface terminates at said upper corner element surface and a lower portion of said second abutment surface terminates at said lower corner element surface;
• two protrusions extending perpendicular to said first abutment surface;
• two protrusions extending perpendicular to said second abutment surface, wherein each of said protrusions has a substantially square cross-sectional profile;
• at least one first deflectable flexible finger extending from said first abutment surface, wherein at least a portion of a primary surface of said at least one first deflectable flexible finger extends substantially perpendicular to said first abutment surface, and wherein said at least one first deflectable flexible finger comprises a tang that extends, proximate a tip of said at least one first deflectable flexible finger, beyond said primary surface of said at least one first deflectable flexible finger;
• and
• at least one second deflectable flexible finger extending from said second abutment surface, wherein at least a portion of a primary surface of said at least one second deflectable flexible finger extends substantially perpendicular to said second abutment surface, and wherein said at least one second deflectable flexible finger comprises a tang that extends, proximate a tip of said at least one second deflectable flexible finger, beyond said primary surface of said at least one second deflectable flexible finger.

A connector element support assembly, comprising:

• a plurality of connector elements, each of said connector elements comprising a body portion having a substantially planar first abutment surface, a substantially planar second abutment surface, and a corner surface, wherein said first abutment surface extends substantially perpendicularly from a first terminating edge of said corner surface, wherein said second abutment surface extends substantially perpendicularly from a second terminating edge of said corner surface, wherein said corner surface extends between a terminating edge of said first abutment surface to a terminating edge of said second abutment surface, wherein said first abutment surface and said second abutment surface are formed at substantially 90° relative to one another, wherein an upper portion of said first abutment surface terminates at a substantially planar upper corner element surface and a lower portion of said first abutment surface terminates at a substantially planar lower corner element surface, and wherein an upper portion of said second abutment surface terminates at said upper corner element surface and a lower portion of said second abutment surface terminates at said lower corner element surface;
• two protrusions extending perpendicular to said first abutment surface;
• two protrusions extending perpendicular to said second abutment surface, wherein each of said protrusions has a substantially square cross-sectional profile;
• at least one first deflectable flexible finger extending from said first abutment surface, wherein at least a portion of a primary surface of said at least one first deflectable flexible finger extends substantially perpendicular to said first abutment surface, and wherein said at least one first deflectable flexible finger comprises a tang that extends, proximate a tip of said at least one first deflectable flexible finger, beyond said primary surface of said at least one first deflectable flexible finger, to form a camming surface and a shoulder;
• at least one second deflectable flexible finger extending from said second abutment surface, wherein at least a portion of a primary surface of said at least one second deflectable flexible finger extends substantially perpendicular to said second abutment surface, and wherein said at least one second deflectable flexible finger comprises a tang that extends, proximate a tip of said at least one second deflectable flexible finger, beyond said primary surface of said at least one second deflectable flexible finger, to form a camming surface and a shoulder;
• at least two header elements, wherein each header element includes an upper horizontal header element bar and a lower horizontal header element bar joined by two or more vertical header element bars, wherein each of said horizontal header element bars includes a header element recess within a portion of each terminal end of said horizontal header element bars, wherein each of said header element recesses is a substantially square cross-sectional recess such that at least one of said protrusions is alignable with and at least partially positionable within at least a portion of a mating one of said header element recesses, and wherein said vertical header element bars are positioned proximate said terminal ends of said horizontal header element bars so as to be engaged by at least a portion of said shoulder of at least one of said at least one first deflectable flexible finger or said shoulder of at least one of said at least one second deflectable flexible finger;
• and
• at least two rail elements, wherein each rail element includes an upper horizontal rail element bar and a lower horizontal rail element bar joined by two or more vertical rail element bars, wherein each of said horizontal rail element bars includes a rail element recess within a portion of each terminal end of said horizontal rail element bars, wherein each of said rail element recesses is a substantially square cross-sectional recess such that at least one of said protrusions is alignable with and at least partially positionable within at least a portion of a mating one of said rail element recesses, and wherein said vertical rail element bars are positioned proximate said terminal ends of said horizontal rail element bars so as to be engaged by at least a portion of said shoulder of at least one of said at least one first deflectable flexible finger or said shoulder of at least one of said at least one second deflectable flexible finger.
