Abstract:
1. A sign-mounting system for mounting a graphic display to a supporting structure, the system comprising: a stationary portion; a rotating portion; the rotating portion rotatably connected to the stationary portion; the stationary portion further comprising at least two flexible spring arms; each of the spring arms comprising a first segment; the first segment comprising a fixed end; the fixed end coupled with a remainder of the stationary portion; each of the spring arms further comprising a second segment; the first and second segments of each of the spring arms coupled at a bend in the spring arm; the second segment comprising a free end; a straight-line distance between the fixed end and the free end being less than a straight-line distance between the free end and the bend; the second segment further comprising a notch; each of the notches securingly engageable to an edge of an opening of the supporting structure; the spring arms being sufficiently flexible to facilitate disengagement from the supporting structure; the stationary portion further comprising at least one stationary helical sliding surface; the rotating portion comprising at least one rotating helical sliding surface; one, of the at least one stationary sliding surfaces, and one, of the at least one rotating sliding surfaces, sliding against each other, when the rotating portion is rotated from an initial stable orientation with respect to the stationary portion; the rotating portion being moved longitudinally upward relative to the stationary portion, by force of the one, of the stationary sliding surfaces, and the one, of the rotating sliding surfaces, against each other when the rotating portion is rotated from the initial orientation; the rotating portion being restored to the initial orientation, by force of the one, of the stationary sliding surfaces, and the one, of the rotating sliding surfaces, against each other, when the rotating portion is allowed to fall after being moved longitudinally upward.
