Abstract

ABSTRACT

Various styles of discrete book holding stands, paper holding stands and combination devices thereof with assorted visual aids have been manufactured over the years. My combination "book and paper holding stand with colour tinted optical filter" is intended primarily for typists and others who operate keyboard devices and provides several functional improvements to previous designs. Most functionally unique is the colour tinted optical filter with size able to cover a normal sheet of paper or both pages of an open book. Recent optical studies have shown individuals with some forms of dyslexia (a reading and learning disability) are in many cases cured by the use of colour tinted eyeglasses. While the manufacture of colour tinted translucent plastic sheet materials has occurred for some time they have to this inventor's knowledge never bean applied in the size described above as a colour tinted optical filter. The effective use of this device is positive upon ease of reading for most people and for some dyslexic people can be a quite dramatic positive effect. Second, the unique rotating plastic dowel and clamp apparatus provide a continually adjustable thickness holding device which can firmly grip single sheets of paper or open books of varying thickness while easily swinging out of the way for page turning of said books. Third the book and paper holding stand will provide for affordable cost by being in nature a purposefully simple design. Patent is applied for in two ways.
First the preferred embodiment of the "book and paper holding stand with colour tinted optical filter" is believed unique in functionality. Second, the "colour tinted optical filter" alone is unique in functionality as defined by it's size and it's perceived application wherein it is a device independent of eyeglasses) with application including and beyond general reading enhancement in that it can be a very useful device in foremost identifying and secondly treating applicable forms of dyslexia.

SPECIFICATION

My invention the "book and papelr holding stand with colour tinted optical filter" is intended foremost as a preferred embodiment complete assembly as a ~c,ok and paper holding device with means for enhancing the optical characteristics of text by a colour tinted translucent optical filter generally intended to aid typists or persons using computar keyboards. A sub-invention -~
area exists wherein most importantly the colour tinted optical ~ilter can b~ used alone as a functional device for identification and treatment of some forms of dyslexia and secondly for reading, optical enhancement purposes for the gqneral publia.
~5 With reference to the above mentioned foremost preferred embodiment appliaation, most present popular designs are adaptable to holding a single printed page by a mechanical sprin~
type clip and with the page underneath of a vertically ~diustable ~lidin~ horizontally mounted translucent plastic ruler. This holding meahanism provides ~everal inconveniences. First a these devices are mostly intended for a single page with a typical maximum of only 3 or 4 pages. Second this clamping design does not lend it~elf easily to holding a book. Third while some optidal benefit i9 derived from the translucent sliding ruler it must b~ continually adiusted vertically for reading purposes thereby slowing a typical typist in the function of his or her work, Fourth, rather expensive molds are required to fabricate this multiple pieoe device.
Devices aapable of holdin~ either a book or page of paper have been de~eloped for example the "Adjustable Book Holder Including Front Magnifying Panel" , United States Patent Number 4,496~1~7 by N~lson. Inconvenience~ in using and fabricating 54~7 this design also ari~e. First the two piece design must be taken apart to turn a book paga. ~econd the two rows of clamping teeth provide for clamping action ~etween preset points as determined by the width of the individual teeth which for a gi~en width of open book might be alternatel~ too tight or too loose a clamping action, Third incorporating this design for average to larger sized books to retain the optical benefits of the magnifying window would roquire either an exceasively lar~e widLh of the device at A proba~le high cost or a smaller magnifying window of width able to co~er only a single page of an open book, Fourth expensive iniection type molds with complex shape would lilcely be required to rnanufacture this two piece device. This book holder possibly becauso of the abo~e mentioned inconveniences has never enjoyed popular commercialized use to the knowledge of this 15 in~entor, -My inventionJ the Book and Paper Halding Stand With Colour Tinted Optical Filter ovarcomes the flaws of the above mentioned device types providing better operational performance and manufacturing tooling cost advantages.
With respect to the sliding ruler type of page holder ~a device currently being sold in Radio Shack stores) my invention provides for easy insertion and manipulation of single or multiple pages of paper or a book of most any thickness or usual height wherein s~id sliding ruler page holder generally holds a single page of paper. My book and paper stand design with the included dowel and clamp apparatus de~eats the rack teeth design of Nelson by providing fully continuous clamping width adjustment with c:lamp, locking action to a given book width, Easier page turning is also provided for wherein this clamp can rotate out the way to turn a page and the Nelson design requires disassembly, The colour tinted optical filter applies the concept of `: 2 [)(35~167 celour filtarlng ~or ~pti.cal be!le~it to a ~ull sh~st o~' paper in i~'s folded clo~d position. This defeat~ the nacessity of continually adjusting a rull3r to a new :Line position as mentioned previously for sliding ruler type paper stands ~aid optical tinted optical filter also defeats Nelsen!s design in firstly cost wherein it is a cheaper item te manufacture than Nelson's front magnifying panel. Secondly, the folding type colour tinted optical filter design within the preferred embodiment of the complete assembly opens to a wider width to more fully cover both pages of an open ~ook unlike Nelson's design which ~y his illustration appears too narrow. Thirdly and perhaps most importantlyJ the incorporation of colour as an optical techni~ue qnhances the appearance of text or images using a wholely different optical principal (from previous known optical enhancing designs of sufficient size able to cover a ~ook or typical sheet o~ paper~ wherein it is observable that colour enhances the readability of text but it is currentl~ not fully understood how the medical or scientific mechanism of this enhancement occuss Typically translucent sheets of plastic comprising lightly tinted yellowl orange and pink colors appear most promising for said colour tinted optical filter application wherein it is believed that these colours are receiv~d normally by t~e eye however their reception invokes chemical reactions in vision related centers of the human brain which provide for a tranquilizing effect reducing normal stress in~olved in the reading process.
Last the previously alluded to low equipment cost overhead in manufacturing either tha colour tinted optical filter or the book and paper holding stand is inherent in the fact that the 30 stand piece, clamp piece and optical filter are manufactured ~y :

hand held power planer, orbital sanderl drill with buffing wheel -~

The purposefully simple design of the book and paper holding stand with colour tinted optical filter can be easi~ manu~actured ~and if necessary modiEied in si~e or shape) well within the limits of ac~opta~le cost~, The available options o~ cornputer numerical controlled cutting and/or injection molding techniques are available or latlar use where product demand and business cash flow deem these app~opriate, The features of the preferred embodiment of this invention are distinctly polnted out in this portion of the specification by a series of eight drawn fi~ures and two photograph figures and refqrred to in Eubsequent text and later in the claims.
