1. A sign-mounting system for mounting a sign to a structure, the system comprising:

  • a frame portion mountable to the sign, the frame portion having a first coupling element; and

    a mounting portion mountable to the structure, the mounting portion having a second coupling element;

    one of the first and second coupling elements defining an inner rim with a generally circular outside surface, and the other of the first and second coupling elements defining an outer rim with a generally circular inside surface, wherein the inner rim fits generally concentrically within the outer rim;

    the outside surface defining at least one inner locking-surface part having a radius that is different than a radius of adjacent portions of the outside surface, the inside surface defining at least one outer locking-surface part having a radius that is different than a radius of adjacent portions of the inside surface;

    wherein the inner rim fits within the outer rim in at least two orientations in which at least one of the at least one inner locking-surface parts and at least one of the at least one outer locking-surface parts engage each other to resist rotation of the first and second coupling elements relative to each other;

    wherein at least one of the at least one inner locking-surface parts has an arc length that is different than an arc length of at least one of the at least one outer locking-surface parts;

    wherein the respective locking-surface parts with different arc lengths engage one another providing a limited range of rotation of the first and second coupling elements relative to each other, and wherein the system further includes a biasing element engaged with the first and second coupling elements, to bias the the first and second coupling elements relative to each other.
