Den foreliggende opfindelse angår et skilt omfattende i det mindste én gennemskinnelig frontplade, på hvilken skiltets tekst eller figur er anbragt eller påtrykt, hvilken tekst omfatter mindst ét syvelement-ciffer, hvis elementer 5 omfatter to forskelligt farvede partier, som er indrettet til på skift at udfylde en åbning i frontpladen, og hvilke elementer er drejelige omkring en parallelt med frontpladen forløbende aksel, i hvilket skilt der bag frontpladen er placeret organer til belysning af frontpladens bagside.The present invention relates to a sign comprising at least one translucent faceplate on which the text or figure of the sign is affixed or printed, the text comprising at least one seven-element digit, the elements of which include two differently colored portions arranged to alternately filling an opening in the faceplate and which elements are rotatable about a shaft extending parallel to the faceplate, in which means are placed behind the faceplate means for illuminating the back of the faceplate.

10 Skilte til prisangivelser gør ofte brug af såkaldte syvelement-cifre, der er sammensat af syv pladeformede elementer, der kan bevæges således, at de i én stilling fremviser en lystfarvet flade og i en anden stilling fremviser en mørkfarvet flade. Skilte med cifre af denne art er kendt fra 15 de tyske offentliggørelsesskrifter nr. 27 06 653, nr. 27 07 241, samt fra tysk patentskrift nr. 28 22 704.10 Signs for price quotations often make use of so-called seven-element digits, which are composed of seven plate-shaped elements, which can be moved so that they show in one position a light colored surface and in another position a dark colored surface. Signs with digits of this kind are known from 15 German Publication No. 27 06 653, No. 27 07 241, and from German Patent No. 28 22 704.

Andre eksempler på skilte, der omfatter bevægelige elementer, findes i beskrivelserne til USA-patenterne nr. 4.040.193 og nr. 4.411.084 samt i beskrivelsen til australsk 20 brugsmønster nr. 35671/84. Ingen af disse eksempler angår imidlertid et skilt, hvor frontpladen er gennemlyst, og hvor cifrenes elementer både i den aktive og i den passive stilling er gennemlyst bagfra. Ved de kendte skilte kan der opnås cifre, som er gennemlyst i aktiv stilling mod en mørk, 25 ikke gennemlyst baggrund eller cifre, som fremstår som sorte, ikke-lysende felter, men ikke skilte, hvor både baggrunden og cifrene er lysende, f.eks. med forskellige farver eller med forskellig lysintensitet. Udseendet og læseligheden af et sådant skilt skæmmes stærkt, hvis indvendige dele ka- .Other examples of signs incorporating movable elements can be found in the disclosures of U.S. Patent Nos. 4,040,193 and 4,411,084 as well as in the specification to Australian Patent Application No. 35671/84. However, none of these examples relate to a sign where the faceplate is illuminated and where the elements of the digits are illuminated from behind both in the active and in the passive position. By the known signs, digits which are illuminated in active position can be obtained against a dark, illuminated background or digits which appear as black, non-illuminated fields, but not signs where both the background and the digits are illuminated, f. eg. with different colors or with different light intensity. The appearance and legibility of such a sign is greatly embarrassed if the inside parts can.

30 ster skygger på frontpladen, eller hvis denne belyses med misfarvet lys.30 shadows on the faceplate or if illuminated with discolored light.

Formålet med opfindelsen er at tilvejebringe et skilt af den indledningsvis nævnte art, dvs. med en fra skiltets indre gennemlyst frontplade, ved hvilket skilt frontpladen 35 kan omfatte cifre, hvis elementer ligeledes er gennemlyst fra skiltets indre både i aktiv og i passiv stilling. Herunder skal såvel frontpladen som cifrene være uden væsentlige skygger eller uens oplyste partier.The object of the invention is to provide a sign of the kind mentioned in the preamble, viz. having a faceplate illuminated faceplate, at which the faceplate faceplate 35 may comprise digits whose elements are also illuminated from the interior of the sign both in active and in passive position. Both the faceplate and the digits must be free of any significant shadows or illuminated areas.

Dette formål opnås ved et skilt af den indledningsvis nævnte art, der ifølge opfindelsen er ejendommeligt ved det i den kendetegnende del af krav 1 angivne.This object is achieved by a sign of the type mentioned in the introduction, which according to the invention is characterized by the part of claim 1.

Ved at placere belysningsorganerne i nogen afstand 5 fra frontpladen vil der opnås en tilnærmelsesvis ensartet belysning af denne, også selvom de er anbragt uden for cifrenes kontur, især fordi det ikke aktive pladeelement har samme afstand fra frontpladen som belysningsorganerne og derfor ikke vil kunne kaste skygger på frontpladen eller 10 kaste væsentlige mængder af lys med en fra frontpladen forskellig farve ned mod denne. De gennemskinnelige bærelegemer er i belysningsmæssig henseende i det væsentlige neutral og kaster ikke skygger. Skiltet ifølge opfindelsen udmærker sig ved at kunne anvendes med næsten alle kombinationer af far-15 ver og lysintensiteter, f.eks. hvide cifre på en lysende, kulørt baggrund, kulørte eller mørke cifre på hvid baggrund eller kulørte cifre og baggrund med forskellig farve.By placing the lighting means at some distance 5 from the faceplate, an approximately uniform illumination will be obtained, even if placed outside the contour of the digits, especially since the inactive plate element has the same distance from the faceplate as the lighting members and therefore will not be able to cast shadows. on the faceplate or throw substantial amounts of light with a color different from the faceplate towards it. The translucent carriers are, for lighting, essentially neutral and do not cast shadows. The sign according to the invention is distinguished by being able to be used with almost all combinations of colors and light intensities, e.g. white digits on a luminous, colored background, colored or dark digits on a white background or colored digits and backgrounds of different color.

En særlig fordelagtig udformning af skiltet, hvor frontpladen og belysningsorganerne er forbundet ved hjælp af 20 bæreskinner, som igen er forbundet ved hjælp af bærerammer, gennem hvilke belysningsorganerne og frontpladerne er tilgængelige, er angivet i krav 4. Udformningen gør udskiftning af belysningsorganernes lamper eller lysstofrør særlig enkel og gør udtagning af frontplader til rengøring til en simpel 25 proces. Ved udformningen ifølge krav 4 er problemer med forskellig varmeudvidelse af frontplader og skiltets bærende dele også løst på en effektiv måde.A particularly advantageous design of the sign in which the faceplate and the illuminating means are connected by means of supporting rails, which in turn are connected by means of supporting frames through which the illuminating means and the faceplates are available, are set out in claim 4. The design makes the replacement of the lamps or fluorescent lamps of the illuminating means. particularly simple and makes removing faceplates for cleaning a simple 25 process. In the design according to claim 4, problems with different heat expansion of the faceplates and the bearing parts of the sign are also effectively solved.

Andre fordele og udformninger ifølge opfindelsen fremgår af de uselvstændige krav samt af den følgende detal-30 jerede beskrivelse, hvor et udførelseseksempel på et skilt ifølge opfindelsen er beskrevet med henvisning til tegningen, på hvilken:Other advantages and embodiments of the invention are apparent from the dependent claims as well as from the following detailed description, in which an exemplary embodiment of a sign according to the invention is described with reference to the drawing, in which:

3 fig. 4 viser et drejeligt element til skiltet ifølge fig. 1 i skrå afbildning, fig. 5 viser et længdesnit gennem et dobbeltsidigt skilt langs linien IV-IV ifølge fig 1, og 5 fig. 6 viser skiltet ifølge fig. 5 set fra enden og med endedækslet delvis bortskåret.3 FIG. 4 shows a rotatable element for the sign according to FIG. 1 in an oblique view; FIG. 5 is a longitudinal section through a double-sided sign taken along the line IV-IV of FIG. 1; and FIG. 6 shows the sign according to FIG. 5 seen from the end and with the end cover partially cut away.

På tegningens fig. 1 er der vist en del af et tværsnit gennem et skilt ifølge opfindelsen. Skiltet omfatter som en del af dets tekst et eller flere cifre af den såkald-10 te syvelement-type. Skiltet har en frontplade 1, på hvilken skiltets øvrige tekst eller figurer er påtrykt. Skiltet er derfor særdeles anvendeligt til prisskiltning eller til angivelse af klokkeslet for togafgange eller lignende. I frontpladen 1, af hvilken en del, der rummer et ciffer, er 15 vist set forfra på fig. 2, er der udskåret syv aflange åbninger 2 for hvert ciffer. Åbningerne er dækket af pladeelementer 3,4, der er af to typer alt efter, om det pågældende element skal være aktivt for at danne det ønskede ciffer eller ikke. På fig. 2 er de aktive pladeelementer betegnet 3, 20 medes det passive er betegnet 4. Det ses, at det på fig. 2 dannede ciffer, er et nital. Frontpladen 1 er gennemskinnelig, således at den vil kunne gennemlyses bagfra. Det samme er pladeelementet 4, der, når det gennemlyses bagfra, skal fremstå med samme farve og lysintensitet som frontpladen.In the drawing FIG. 1, a portion of a cross section through a sign according to the invention is shown. The sign comprises as part of its text one or more digits of the so-called seven element type. The sign has a front plate 1 on which the other text or figures of the sign are printed. The sign is therefore very useful for price signage or for indicating the time of train departures or the like. In the faceplate 1, of which a portion containing a digit is shown from the front in FIG. 2, seven elongate apertures 2 have been cut for each digit. The openings are covered by plate elements 3,4, which are of two types depending on whether the element in question must be active to form the desired digit or not. In FIG. 2, the active plate elements are designated 3, 20 while the passive ones are designated 4. It can be seen that in FIG. 2 digits formed, is a nital. The front plate 1 is translucent so that it can be illuminated from behind. The same is the plate element 4 which, when illuminated from behind, must appear with the same color and light intensity as the faceplate.

25 Den anden type pladeelementer er også gennemskinnelige, men har en anden farve end frontpladen. De kan eventuelt også have en større tykkelse end frontpladen 2, hvorved de kommer til at fremstå som forhøjede partier i forhold til frontpladen. Den derved opnåede reliefvirkning medvirker til at for-30 øge læseligheden af cifrene. Cifrenes elementer er vist på fig. 4 i større målestok. Pladedelene 3,4 er fastgjort til et bærelegeme 5, der generelt har form som et H. Midt på H'ets tværbjælke er der en lejeboring 6, ved hjælp af hvilken elementet kan monteres på en akseltap. Bærelegemet er 35 fremstillet af gennemsigtigt materiale, fortrinsvis klar akryl. Omkring lejeboringen er der anbragt et ligeledes af gennemsigtigt materiale fremstillet drivhjul 7, der fortrinsvis er forsynet med en fortanding. På bærelegemet er25 The other type of plate elements are also translucent, but have a different color from the front plate. They may also have a greater thickness than the faceplate 2, thereby appearing as raised portions relative to the faceplate. The relief effect thus obtained helps to increase the readability of the digits. The elements of the digits are shown in FIG. 4 on a larger scale. The plate members 3, 4 are attached to a support body 5, generally in the form of an H. In the middle of the transverse beam of the H there is a bearing bore 6, by means of which the element can be mounted on a shaft pin. The support is made of transparent material, preferably clear acrylic. Surrounding the bearing bore is also a drive wheel 7 made of transparent material, which is preferably provided with a tooth. On the body is

4 der endvidere fastgjort et par tappe 8 af magnetisk materiale. Disse tappe tjener som anslag mod en holdemagnet til begrænsning af elementets drejebevægelse omkring akseltappen som forklaret nedenfor. Ved belysning af pladedelen 4 fra 5 den med bærelegemet forbundne del vil skyggevirkningen være minimal, fordi bærelegemet er gennemsigtigt og fordi berøringsfladen på grund af bærelegemets H-form er lille. Pladedelene er forsynet med affasninger 9, der gør det muligt for elementet at dreje i åbningerne med en tæt pasning, der kun 10 efterlader en meget smal spalte, gennem hvilken lys kan trænge ud, eller gennem hvilken man kan se ind i skiltets indre.4 which furthermore attaches a pair of pins 8 of magnetic material. These pins serve as a stop against a holding magnet to limit the rotational movement of the element around the shaft pin as explained below. By illuminating the plate portion 4 out of 5 the portion associated with the support body, the shading effect is minimal because the support body is transparent and because the contact surface due to the H shape of the support body is small. The plate parts are provided with bevels 9 which allow the element to rotate in the openings with a tight fit leaving only 10 a very narrow gap through which light can penetrate or through which one can see into the interior of the sign.

Af hensyn til at de syv elementer skal kunne opfattes som et sammenhængende ciffer, skal afstanden mellem ud-15 skæringerne 2 være så lille som muligt, og bevægelsesbanerne for pladedelene 3,4 ved tilstødende cifferelementer vil derfor overlappe hinanden. På grund af bærelegemets H-form kan to tæt op mod hinanden placerede cifferelementer godt drejes uden at kollidere, fordi bærelegemet·ikke rager uden for 20 forbindelseslinien mellem enderne af pladeelementerne 3,4.In order for the seven elements to be perceived as a coherent digit, the distance between the cut-outs 2 must be as small as possible, and the paths of movement of the plate parts 3,4 by adjacent digit elements will therefore overlap. Due to the H-shape of the support body, two closely spaced digit elements can be easily rotated without colliding, because the support body · does not extend outside the connecting line between the ends of the plate elements 3,4.

Det må dog påses, at to op til hinanden stødende cifferelementer ikke drejes samtidig, idet enderne af pladelementerne derved kan komme til at kollidere.However, it must be ensured that two adjacent digit elements are not rotated at the same time, as the ends of the plate elements may thereby collide.

De på fig. 4 viste elementer er monteret på et chas-25 sis, der består af sidestykker 10, endestykker 11 og en tværvæg 12. Chassiset er fremstillet af gennemsigtigt materiale, f.eks. klar akrylplade. Chassiset tjener til montering af de akseltappe 13, som elementerne drejer om, en per-manentmagnetmotor 14 for hvert element og for anslagsmagne-30 ter 15 (fig. 3), der begrænser elementernes drejningsvinkler og fastholder elementerne i endestillingerne for deres dre-jebevægelser, således at rystelser eller lignende ikke kan få elementerne til at dreje pladedelene ud af plan med frontpladen 1. På akslen af hver permanentmagnetmotor er der 35 monteret et drev 16, der er i indgreb med drivhjulet 6 på elementerne. Som det fremgår af fig. 3, der viser et snit gennem frontpladen 1 ud for enden af chassiset til et ciffer, er endestykket delvis bortskåret, hvorved et cifferele-The figures of FIG. 4 is mounted on a chassis consisting of side pieces 10, end pieces 11 and a transverse wall 12. The chassis is made of transparent material, e.g. clear acrylic plate. The chassis serves to mount the shaft pins 13 about which the elements rotate, a permanent magnet motor 14 for each element, and for impact magnets 30 (Fig. 3), which limit the angles of rotation of the elements and retain the elements in the end positions for their pivotal movements. such that shakes or the like cannot cause the elements to rotate the plate parts out of plane with the front plate 1. On the shaft of each permanent magnet motor, a drive 16 is mounted which engages the drive wheel 6 on the elements. As shown in FIG. 3, showing a section through the front plate 1 at the end of the chassis for a digit, the end piece is partially cut away, whereby a

5 ment, der er fastgjort til et sidestykke bliver synligt og en anslagsmagnet 15 bliver også synlig. Det bemærkes, at de på sidestykkerne og tværvæggen anbragte permanentmagnetmoto-rer er anbragt i større afstand fra frontpladen end aksel-5 tappene 13 for derved at formindske muligheden for skyggedannelse på frontpladen. Motorerne på endestykkerne 11 er dog anbragt på samme højde som akseltappene 13 for at give plads for belysningsorganerne. Ved at anbringe cifferelementerne på et chassis, der er klæbet fast til frontpladen, vil 10 virkningen af forskelle i varmeudvidelse mellem frontpladen og de øvrige dele i cifferet blive minimal, og de drejelige elementer vil derfor være frit bevægelige selv med snævre tolerancer, uanset om frontpladen på grund af solindfald udsættes for stærk opvarmning og deraf følgende varmeudvidel-15 se.5 attached to a side piece becomes visible and an impact magnet 15 also becomes visible. It should be noted that the permanent magnet motors placed on the side pieces and the transverse wall are located at a greater distance from the front plate than the shaft pins 13, thereby reducing the possibility of shadow formation on the front plate. However, the motors on the end pieces 11 are positioned at the same height as the shaft pins 13 to make room for the lighting means. By placing the digit elements on a chassis adhered to the faceplate, the effect of differences in heat expansion between the faceplate and the other parts of the digit will be minimal, and the rotatable elements will therefore be freely movable even with narrow tolerances, regardless of the faceplate. due to solar incidence is subjected to strong heating and consequent heat expansion.

Som det fremgår af fig. 1 er frontpladen 1 monteret i et spor 17 langs kanten af en bæreskinne 18. Bæreskinnen er forsynet med et yderligere spor 19, der tjener til fastholdelse af en slæde 20, på hvilken belysningsorganerne i form 20 af et lysstofrør 21 er monteret. Det ses, at lysstofrøret 21 er placeret i tilnærmelsesvis samme afstand fra frontpladen 1 som de pladelementer, der ikke befinder sig i udskæringerne i frontpladen. Disse ikke aktive pladelementer kan derfor ikke danne skygge på frontpladen på grund af det lys, som 25 belysningsorganerne afgiver. På tilsvarende måde ved hjælp af en modstående bæreskinne er frontpladens anden kant forbundet med et andet belysningsorgan. Til beskyttelse af skiltets bevægelige dele og de på frontpladen anbragte tekster og figurer er skiltet omgivet af ydre gennemsigtigt rør 30 22, der består af akryl eller polykarbonat, alt efter om man lægger størst vægt på lysbestandighed eller stor slagstyrke.As shown in FIG. 1, the faceplate 1 is mounted in a groove 17 along the edge of a carrier rail 18. The carrier rail is provided with a further groove 19 which serves to hold a carriage 20 on which the illuminating means in the form 20 of a fluorescent tube 21 are mounted. It will be seen that the fluorescent tube 21 is located at approximately the same distance from the faceplate 1 as the plate elements not located in the cutouts in the faceplate. Therefore, these inactive plate elements cannot create shade on the front plate due to the light emitted by the illuminating means. Similarly, by means of an opposing support rail, the other edge of the faceplate is connected to another illuminating means. To protect the moving parts of the sign and the texts and figures affixed to the faceplate, the sign is surrounded by outer transparent tube 30 22, which consists of acrylic or polycarbonate, depending on the greatest emphasis on light resistance or high impact strength.

De to bæreskinner 18 er, som det fremgår af det på fig. 5 viste længdesnit gennem et dobbeltsidet skilt, ved enderne fastgjort til et par bærerammer 23, der danner luk-35 kede rammer omkring en central åbning 24, der bedst ses på fig. 6, gennem hvilken såvel frontpladen 1 som belysningsorganerne er tilgængelige og eventuelt udskiftelige. Lysstofroret 21, som er anbragt på en slæde 20, kan trækkes ud i 6The two support rails 18 are as shown in FIG. 5 shows a longitudinal section through a double-sided sign, attached at the ends to a pair of supporting frames 23, forming closed frames around a central opening 24, which is best seen in FIG. 6, through which both the faceplate 1 and the lighting means are accessible and possibly interchangeable. The fluorescent lamp 21 mounted on a carriage 20 can be pulled out in 6

dets længderetning, idet strømforsyningen, der er udformet som en stikforbindelse 25, derved samtidig afbrydes. Tilsvarende kan frontpladerne udtrækkes af disses spor til rengøring eller til eftersyn af de derpå monterede bevægelige 5 cifre. Det gennemsigtige rør 22 er monteret uden på bærerammerne 23, og den centrale åbning i bærerammerne er aflukket ved hjælp af et dæksel 26, der med mellemlæg af en pakning 27 med en kant griber fast på ydersiden af røret 22. Endedækslet 26 kan som vist på fig. 6 eventuelt være forsynet 10 med en luftventil 28, der er forsynet med et filter, således at snavs og småinsekter ikke kan trænge ind i det indre af skiltet. Inden for endedækslerne 26 kan der anbringes nogle indvendige endeplader 29, der kan tjene til fastgørelse af de forskellige forsyningselementer til belysningen, såsom 15 strømforsyningstransformatorer 30, eller til fastgørelse af logiske kredsløb eller lignede styringsudstyr til bevægelse af cifrenes bevægelige elementer.its longitudinal direction, thereby interrupting the power supply, which is formed as a plug connection 25. Similarly, the faceplates can be pulled out of their grooves for cleaning or for inspection of the movable 5 digits mounted thereon. The transparent tube 22 is mounted externally on the support frames 23 and the central opening in the support frames is closed by a cover 26 which interposes a gasket 27 with an edge on the outside of the tube 22. The end cover 26 can as shown on FIG. 6 may optionally be provided with an air valve 28 provided with a filter so that dirt and small insects cannot penetrate the interior of the sign. Within the end covers 26 may be provided some inner end plates 29 which may serve to attach the various lighting elements to the lighting, such as 15 power supply transformers 30, or to secure logic circuits or similar control devices for moving the moving elements of the digits.

Skiltet ifølge opfindelsen er egnet til fremstilling af modulære skilte, der kan opsættes over hinanden i en 20 fælles ramme, hvor skiltene med bevægelige cifre kombineres med skilte, der er opbygges på samme måde, men hvor front-pladerne ikke indeholder bevægelige cifre, men tekst og figurer .The sign according to the invention is suitable for the production of modular signs which can be mounted over one another in a common frame where the signs with movable digits are combined with signs which are constructed in the same way, but where the faceplates do not contain movable digits but text. and figures.
