Abstract
A weather-proof changeable-type readerboard signage system comprising a signboard having a substantially planar surface, and supportable above the Earth's surface at a predetermined viewing height. A pair of upper and lower character holding tracks are attached to the substantially planar surface of the signboard and extend in a parallel manner relative to each other by a predetermined distance. A plurality of character substrates of rectangular geometry, bearing a graphical character, and having a height dimension slightly less than the predetermined distance, are front loadable into the pair of upper and lower character holding tracks, and releasably retained therewithin so as to form a string of characters displaying a readable message. A character-protective viewing panel of optically transparent construction is slidably retained within the upper and lower character holding tracks in conjunction with the plurality of character substrates, so that the character-protective viewing panel is physically disposed over the plurality of character substrates and releasably secured to the signboard by one or more fastening elements passed through the character-protective viewing panel and secured into the signboard so as to prevent unauthorized removal of the character substrates from the upper and lower character holding tracks, while protecting the character substrates against mischief and vandalism, and natural elements presented in outdoor environments.
