Rackable panel assembly and methods of assembly thereof

A rackable panel assembly comprising:

• a plurality of vertical members each having a pair of opposed ends and at least one sidewall extending longitudinally therebetween and having a rail engagement opening defined therein;
• at least one rail having a pair of opposed ends and at least an upper wall and an opposed lower wall extending longitudinally therebetween, said upper wall and said lower wall defining sets of opposed openings spaced along a longitudinal length of the at least one rail, each set of opposed openings comprising an upper wall opening formed in the upper wall and a corresponding lower wall opening formed in the lower wall and defining a through passage extending between the upper wall opening and the lower wall opening adapted to receive a vertical member of said plurality of vertical members therethrough and at least partially overlap or cover the rail engagement opening of said vertical member;
• and
• a plurality of coupling members, wherein at least one coupling member of the plurality of coupling members is adapted to be at least partially received in each said vertical member for pivotally coupling the vertical member to the at least one rail, said each coupling member having at least one protrusion and a biasing member for biasing the at least one protrusion outwardly from the rail engagement opening in a direction perpendicular to the length of the at least one rail, said at least one protrusion of each coupling member including an upper wall and an opposed lower wall interconnected by a pair of opposed end walls and a pair of opposed sidewalls,
• wherein at least one of the upper wall opening and the lower wall opening of each set of opposed openings is elongate so that said vertical member received therethrough is pivotable relative to the at least one rail, and
• wherein the opposed end walls of the at least one protrusion are configured to at least partially abut against an inner surface of the upper wall of the rail and an inner surface of the opposed lower wall of the rail to at least partially prevent axial movement of the vertical member relative to the rail when pivotally coupled together.
