Abstract
A device for displaying a scrollable banner wherein the single banner pick-up roller used in prior art devices is replaced by a multi-roller spool. Each multi-roller spool comprises at least two rollers connected with spool belts which define a winding area much longer than that of any single roller. The spools are rotatably mounted within a display housing. Motors drive the multi-roller spools. Additional features include: convex style crowned pulleys for automatically centering each of the spool belts, a centrally located roller separator mechanism which gives a convex crown structure to the entire spool itself whereby the banner is automatically centered, and a display housing of far reduced depth.
Claims31
A scrolling display apparatus which comprises:
- a quadrangular shallow enclosure;
- first and second rollers rotatively mounted in a side-by-side, space-apart and parallel arrangement inside said enclosure;
- third and fourth rollers rotatively mounted in a side-by-side, spaced apart and parallel arrangement inside said enclosure and apart from said first and second rollers wherein said second roller is located between said first and third rollers;
- a scroll having a first end portion wound around said first and second rollers and an opposite end portion wound around said third and fourth rollers, leaving a central portion of said scroll spread taut across a display area between said first and fourth rollers;
- means for rotating said rollers in a common direction to move said scroll across said display area as said end portions are alternately wound and unwound from said first and second rollers towards said fourth and third rollers and vice-versa;
- and
- at least one first resiliently stretchable spool belt mounted around said first and second rollers under said first end portion;
- and
- at least one second resiliently stretchable spool belt mounted around said third and fourth rollers under said opposite end portion.
A scrolling display apparatus which comprises:
- a substantially quadrangular shallow enclosure having top and bottom ends and a front viewing window;
- a first scroll pick-up spool positioned adjacent to said top end of said enclosure;
- a second scroll pick-up spool positioned adjacent to said bottom end of said enclosure;
- said first and second spools positioned in a side-by-side, space-apart and parallel arrangement inside said enclosure;
- each of said spools comprising:
- a rotatively mounted drive roller;
- a rotatively mounted floating roller positioned in a side-by-side, space-apart and parallel arrangement with said drive roller;
- a scroll having a first end portion wound around said first spool and an opposite end portion wound around said second spool, leaving a central portion of said scroll spread taut between said first and second spools;
- and
- means for rotating said rollers in a common direction to move said scroll between said spools as said end portions are alternately wound and unwound from said first spool towards said second spool and vice-versa;
- wherein each of said spools comprises:
- at least one first resiliently stretchable spool belt mounted around said drive and floating rollers.
A scrolling display apparatus which comprises:
- first and second scroll pickup spools;
- a scroll having a first end portion wound upon said first spool and an opposite end portion wound upon said second spool;
- wherein said first spool comprises:
- first and second rollers rotatively mounted to said apparatus in a substantially side-by-side, spaced-apart arrangement;
- at least one spool belt mounted around said rollers under said first end portion;
- and
- means for rotating said rollers in a common direction to wind said first end portion onto said first spool.
