Abstract
A readerboard signage system which allows signage characters to be easily changed within a pair of parallel extending tracks. In the illustrative embodiments, the system includes an optically transparent character protective viewing panel that is placed over the sequence of characters held in place within the pair of parallel extending tracks. The panel includes a lip portion which cooperates with the lower character holding track, to prevent rain, ice, and snow from entering the tracks, while the viewing panel itself protects the underlying characters from such natural elements and vandalism, without detracting from the utility and aesthetic appearance of the system.
Claims4
A weather-proof changeable-type readerboard signage system, comprising:
- a signboard having a substantially planar surface;
- at least one pair of upper and lower character holding tracks, each said pair of upper and lower character holding tracks being attached to the substantially planar surface of said signboard and extending in a parallel manner relative to each other by a predetermined distance;
- a plurality of character substrates of rectangular geometry, each said character substrate bearing a graphical character and having a height dimension slightly less than said predetermined distance so as to be front loadable into one said pair of upper and lower character holding tracks, and releasably retained therewithin so as to form a string of characters displaying a readable message;
- and
- a character-protective viewing panel of optically transparent construction, slidably retained within each said pair of upper and lower character holding tracks in conjunction with said plurality of character substrates, so that said character-protective viewing panel is physically disposed over said plurality of character substrates and releasably secured to said signboard by one or more fastening elements passed through said character-protective viewing panel and into said signboard so as to prevent unauthorized removal of said character substrates from each said pair of upper and lower character holding tracks, while protecting said character substrates against mischief and vandalism, and natural elements presented in outdoor environments.
