Abstract:
A kit of components for implementing a scrolling banner sign inside a hexahedral display case, said display case including a front panel having a window cut-out and a pair of substantially parallel and opposite longitudinal walls;said kit consisting essentially of:first and second rails, said rails being longitudinally substantially commensurate with one of said longitudinal walls, and means for attaching said rails to said longitudinal walls, said first rail mounting a pair of pintles oriented in a direction perpendicular to said longitudinal wall, said pintles being located proximately to opposite ends of said first rail, and being resiliently and axially biased away from said rail;said second rail mounting a pair of drive units, each in a position opposite and aligned with, one of said pintles;each of said drive units consisting essentially of a mounting module, a directionally reversable electrical motor having a pair of forward and reverse terminals, and gear-down assembly having a drive spindle;a pair of rollers, each having a first axial end shaped and dimensioned to engage one of said pintles, and an opposite second axial end shaped and dimensioned to engage one of said drive spindles;a banner scroll having means at opposite ends for attachment to said rollers;a transformer; anda switch assembly consisting essentially of a rectifier, a switch, pair of diodes, and a set of conductors wired to apply a step-down voltage from said transformer to said rectifier, and a rectified power from said rectifier to said motors through said diodes in alternately switchable polarities.
