Support and related shelf

A support apparatus comprising:

• at least one shelf member having a longitudinal axis, first and second oppositely facing end surfaces essentially perpendicular to the axis and a rear surface essentially parallel to the axis;
• first and second rear extending members mounted to and extending from the rear surface essentially perpendicular to the axis and adjacent the first and second end surfaces, respectively, a top surface of the first rear extending member forming a first bearing surface and a top surface of the second rear extending member forming an additional first bearing surface;
• first and second end extending members mounted to and extending from the first and second end surfaces essentially parallel to the axis, a bottom surface of the first end extending member forming a second bearing surface and a bottom surface of the additional first end extending member forming an additional second bearing surface, a first plane parallel to the first end surface and passing through the second bearing surface, the first and second bearing surfaces defining a first dimension in the first plane, a third plane parallel to the second end surface and passing through the additional second bearing surface, the additional first and additional second bearing surfaces defining the first dimension in the third plane;
• and
• first and second essentially upright frame members, the first frame member including essentially perpendicular first and second walls, the second frame member including essentially perpendicular third and fourth walls, the first wall having a distal edge facing in a direction opposite the second wall and forming a first opening delineator including a third bearing surface and a passageway that opens to form an egress through the distal edge of the first wall in a direction opposite the second wall, the passageway wide enough that the first extending member can pass therethrough, the second wall forming a first rear coupler, a downwardly facing surface of the first rear coupler forming a fourth bearing surface, a second plane essentially parallel to the first wall, the third and fourth bearing surfaces defining an essentially horizontal second dimension in the second plane that is essentially equal to the first dimension, the third wall having a distal edge facing in a direction opposite the fourth wall and forming a second opening delineator including an additional third bearing surface and a passageway that opens to form a second egress through the distal edge of the third wall in a direction opposite the fourth wall, the passageway wide enough that the second extending member can pass therethrough, the fourth wall forming a second rear coupler, a downwardly facing surface of the second rear coupler forming an additional fourth bearing surface, a fourth plane essentially parallel to the third wall, the additional third and additional fourth bearing surfaces defining an essentially horizontal second dimension in the fourth plane that is essentially equal to the first dimension;
• wherein, the shelf member may be operatively mounted to the frame member in a horizontal position wherein the first bearing surface bears against the fourth bearing surface, the second bearing surface bears against the third bearing surface, the additional first bearing surface bears against the additional fourth bearing surface and the additional second bearing surface bears against the additional third bearing surface.
