Patent ID: 7520693

Claim:
A connection joint comprising: a first piece that defines a boss projecting from a planar surface; a second piece that defines a first planar portion that lies against the planar surface of the first piece, the first planar portion defining a first through hole within which the boss resides when the first portion is slid onto the planar surface such that the first portion resiliently flexes to pass over the boss, the second piece further defining a second planar portion having a first end perpendicularly extending from an end of the first planar portion, the second piece further defining a third planar portion parallel to the first planar portion and perpendicularly extending from a second end of the second planar portion; a plurality of strengthening ribs extending between the second portion and the third portion to provide strength to a connection of the first planar portion and the third planar portion; a bevel on the first portion of the second piece that initially contacts the boss and permits a part of the second piece to resiliently flex and pass over the boss, wherein the first piece further defines a second hole, wherein the second hole is threaded and is aligned with the first hole when the boss is received within the first hole; wherein the boss abuts an inside diameter of the first hole formed by the part of the second piece that passes over the boss, and the second portion abuts against the first piece to create a snug fit between the second piece and the first piece; a third piece that lies upon the first planar portion of the second piece opposite the first piece, the third piece defining a third hole that is aligned with the first and second holes when the boss is received with the first hole; and a threaded screw that passes through the first, second and third holes when the boss is received within the first hole to secure the first, second and third pieces together.
