Sign mounting system and elongated sign mounting member therefor

An elongated sign mounting member assembly for a sign mounting system for tautly mounting a flexible material sign to an associated structure, comprising:

• an elongated base member adapted to be mounted to the associated sign structure, the elongated base member including a planar portion and a mounting portion defining a groove therein;
• at least one mounting spring for tautly mounting the flexible material sign to the elongated base member, the at least one mounting spring having a first end secured to the elongated base member and a second end secured to the flexible material sign;
• and
• an elongated cover member complementarily and removably secured to the elongated base member for covering the at least one mounting spring, the elongated cover member being flexibly hinged to the elongated base member for allowing access to the at least one mounting spring;
• and
• wherein the groove is defined as having a slit portion through which the elongated cover member is received and an enlarged base portion into which the elongated cover member is received, the enlarged base portion being sized larger than the slit portion to prevent pull-out of the elongated cover member through the slit portion of the groove.
