Patent ID: 7107714

Claim:
A support structure for a display device comprising: a cross bar having a sign bracket located between a first end and a second end; a first pair of legs; a first coupling defining a first transverse cavity and a first pair of axial cavities, said first transverse cavity receiving said first end of said cross bar and each of said first pair of axial cavities receiving an end of one of said first pair of legs; a second pair of legs; a second coupling defining a second transverse cavity and a second pair of axial cavities, said second transverse cavity receiving said second end of said cross bar and each of said second pair of axial cavities receiving an end of one of said second pair of legs; and a locking mechanism disposed in a member selected from the group consisting of said cross bar and said first pair of legs, said locking mechanism including a detent biased to an extended position wherein at least a portion of said detent extends from said member and engages said first coupling to attach said member to said first coupling and positionable to a retracted position wherein said detent is within said member and disengages said first coupling to detach said member from said first coupling.
