Description
Belysningsarmatur. Lighting fixture.
Oppfinnelsen vedrorer en belysningsarmatur omfattende en basisplate beregnet på å festes på en boks, en vegg, et tak eller lignende, en lampeholder samt en hylselignende gjengekrave for innskruing av en kuppel, hvor gjengekraven er utfort i et fra basisplaten separat stykke og er fastlåsbar til basisplaten ved hjelp av et i denn^e festet spennorgan. The invention relates to a lighting fixture comprising a base plate intended to be attached to a box, a wall, a ceiling or the like, a lamp holder and a sleeve-like threaded collar for screwing in a dome, where the threaded collar is extended in a separate piece from the base plate and is lockable to the base plate by means of an in denn^e fixed clamping device.
u r t u r t
I belysnings armaturer, av. nevnte slag hvor den i armaturen inn-skrudde kuppel har eiingpesiell form eller er forsynt med tekst, , sifre, bokstaver elJeÆgiigijiende, er det av storste betydning at og elektrol; In lighting fittings, of. said type where the dome screwed into the fixture has a special shape or is provided with text, numbers, letters etc., it is of the greatest importance that and electro;
den fastskrudde kuppel vil innta en bestemt stilling i forhold ti.\ omgivelsene, dvs. det underlag armaturen er festet til. Således må en kuppel som angir f.eks. et husnummer, ijtnnta en helt bestemt stilling. the screwed dome will take a specific position in relation to the surroundings, i.e. the surface to which the luminaire is attached. Thus, a dome that indicates e.g. a house number, ijtnnta a completely specific position.
I^vanlige belysningsarmaturer har armaturens basisplote og gjengéde krave hittil vært fremstilt i ett stykke, hvorfor kuppelens stilling, når den er helt innskrudd i kravens gjenge, In ordinary lighting fixtures, the fixture's base plate and threaded collar have so far been produced in one piece, which is why the position of the dome, when it is completely screwed into the thread of the collar,
.ér helt avhengig av hvilken stilling gjengen måtte innta hår armaturen er festet i underlaget. For å tilveiebringe en mulig-het for å justere kuppelens endelige stilling er. dét kjent å utfore de i armaturens basisplate forekommende hull for de skruer ved hjelp av hvilke armaturen festes i underlaget, bue-: formet avlange. Da hullene selvsagt ikke kan strekke seg rundt hele basisplaten, men maksimalt over en strekning på ca. 60° for at ikke basisplaten skal svekkes i uheldig grad, muliggjor en slik losning kun en begrenset innstillingsmulighet som ofte ikke er tilstrekkelig. Til dette kommer at ledningen til lampeholderen blir vridd ved innstillingen av basisplaten, hvilket ikke er tillatt.~ .depends entirely on the position the group takes when the fixture is fixed in the substrate. To provide a possibility to adjust the final position of the dome is. it is known to make the holes in the fixture's base plate for the screws with the help of which the fixture is attached to the base, arc-shaped oblong. As the holes cannot of course extend around the entire base plate, but at most over a stretch of approx. 60° so that the base plate is not weakened to an unfavorable degree, such a release only enables a limited setting option which is often not sufficient. In addition to this, the cord of the lamp holder is twisted when setting the base plate, which is not allowed.~
Det er også tidligere kjent å utfore gjengekraven i et fra bunnplaten separat stykke for derved å oppnå et fjærende feste av kuppelen, raeni, en slik utfprelse er også beheftet med samme ulemper som anfbrt ovenfor efter som den separate gjengekrave kan fikseres i bunnplaten kun i en helt bestemt stilling rela-tivt bunnplaten. It is also previously known to make the threaded collar in a separate piece from the base plate in order to thereby achieve a springy attachment of the dome, raeni, such an embodiment is also subject to the same disadvantages as stated above since the separate threaded collar can be fixed in the base plate only in a completely determined position relative to the base plate.
Et formål med oppfinnelsen er å eliminere foran nevnte ulemper, og belysningsarmaturen ifolge oppfinnelsen kjennetegnes i det vesentlige ved at spennorganet i ikke spent tilstand tillater en dreining av gjengekraven omkring dennes akse, uhindret i forhold til basisplaten og lampeholderen. One purpose of the invention is to eliminate the disadvantages mentioned above, and the lighting fixture according to the invention is essentially characterized by the fact that the tensioning member in a non-tensioned state allows a turning of the threaded collar around its axis, unhindered in relation to the base plate and the lamp holder.
Ifolge oppfinnelsen tilveiebringes en belysningsarmatur som muliggjor en. innstilling av kuppelen i ncyaktig onsket stilling, helt uavhengig av i hvilken stilling armaturens basisplate fastskrus til underlaget takket være at den^gjengede krav er anord-net ubegrenset dreibar i forhold til basisplaten og fastlåsbår til basisplaten i en hvilken som helst dreiet stilling. Ifolge oppfinnelsen kan innstilling av kuppelen, dvs. dreining av gjengekraven, skje uten å rokke ved lampeholderen og dehnes led-ning. According to the invention, a lighting fixture is provided which enables a. setting the dome in exactly the desired position, completely independent of the position in which the fixture's base plate is screwed to the substrate, thanks to the fact that the threaded rod is arranged to be infinitely rotatable in relation to the base plate and can be locked to the base plate in any rotated position. According to the invention, setting the dome, i.e. turning the threaded collar, can take place without shaking the lamp holder and its cable.
Foruten denne fininnstilling byr oppfinnelsen på en mulighet- In addition to this fine-tuning, the invention offers a possibility
for å fremstille armaturen på en vesentlig: enklere og fjilligere måte enn konvensjonell belysningsarmatur, dels ved at utformning av bueÉormede hull i basisplaten kan unngås og dels ved at gjengene for kuppelen kan utformes i et separat ringformet platestykke, fortrinnsvis av ifiptall. Utformftiligen av avlange hull, gjenger og lignende i legemer forer som kjent til hoyé verktoyomkostninger og ka& enklere og billigere utfores i platemateriale. in order to produce the fixture in a significantly: simpler and more delicate way than conventional lighting fixtures, partly by the fact that the design of arcuate holes in the base plate can be avoided and partly by the fact that the threads for the dome can be formed in a separate ring-shaped piece of plate, preferably of iphiptal. The design of oblong holes, threads and the like in bodies leads, as is well known, to high tooling costs and can be carried out more easily and cheaply in sheet material.
Oppfinnelsen skal beskrive» nærmere i det efterfblgendé Ved hjelp av utforelsesekserepler under henvisning til tegningene hvorpå The invention shall be described in more detail in the following By means of exemplary embodiments with reference to the drawings on which
figurene 1-4 viser i aksialt tverrsnitt bre forskjellige ut-forelsesformer av en belysningsarmatur ifolge oppfinfcfilsen. Figures 1-4 show, in axial cross-section, various embodiments of a lighting fixture according to the invention.
Belysningsarmaturen ifolge figurene 1 og 2 omfatter en plan, rund basisplate 1 av platemateriale, beregnet på å festes med ikke-viste skruer til en vegg, et tak eller lignende eller på The lighting fixture according to figures 1 and 2 comprises a flat, round base plate 1 of plate material, intended to be fixed with screws not shown to a wall, a ceiling or the like or on
en boks eller annet underlag samt en gjenget krav 2 som danner en innvendig gjenge 3 for en ikke-vist lampekuppel, beregnet på å skrus inn i armaturen. Videre omfatter armaturen en sentral lampeholder 4 som er festet til basisplaten 1, samt en spennring 5 av metall slik dimensjonert at den kan innpasses omkring lampeholderen mellom denne og gjengekraven. Gjengekraven er utformet med en indre flens 6, og lampeholderen har et lignende fremspring 7. Spénniringen er fastskrubar til basisplaten ved hjelp av skruer 8 for; å ligge an mot flensen 6 reap. fremspringet 7. Som det fremgår av fig. 1, medfbrer en a box or other base as well as a threaded claim 2 which forms an internal thread 3 for a lamp dome not shown, intended to be screwed into the luminaire. Furthermore, the fixture comprises a central lamp holder 4 which is attached to the base plate 1, as well as a clamping ring 5 of metal so dimensioned that it can be fitted around the lamp holder between this and the threaded collar. The threaded collar is designed with an inner flange 6, and the lamp holder has a similar projection 7. The clamping ring can be screwed to the base plate by means of screws 8 for; to rest against the flange 6 reap. the projection 7. As can be seen from fig. 1, includes one
i Lsen tiltrekning av skruene 8 en solid fastlåsning av gjen^kraven 2 By tightening the screws 8, a solid locking of the collar 2 is achieved
i basisplaten 1. Lbsning av skruene muliggjor derimot en ubegrenset dreining av gjengekraven i forhold til basisplaten. in the base plate 1. Loosening the screws, on the other hand, enables unlimited turning of the threaded collar in relation to the base plate.
Ved montering av armaturen fastskrus basisplaten samt lampeholderen fast til underlaget, hvorefter gjengekraven og spennringen anbringes på plass og fastlåses. Hvis den påskrudde kuppel ikke kommer i riktig stilling, fjernes kuppelen, og spennringen losnes slik at gjengekraven kan dreies til den onskede, nye stilling, hvorefter ringen igjen fastspennes. When installing the luminaire, the base plate and the lamp holder are screwed to the base, after which the threaded collar and clamping ring are placed in place and locked. If the screwed-on dome does not come into the correct position, the dome is removed, and the clamping ring is loosened so that the threaded collar can be turned to the desired, new position, after which the ring is clamped again.
Den i fig. 3 antydede utforelsesform avviker fra den i figurene 1 og 2 i det vesentlige hva angår gjengekraven og spennringen. The one in fig. 3 indicated embodiment deviates from that in Figures 1 and 2 essentially as regards the threaded collar and the clamping ring.
Gjengekraven omfatter dels en ringformet gjengedel 21 av metall og dels et ytre mantelstykke 22. Gjengedelen er i den indre The threaded collar comprises partly an annular threaded part 21 made of metal and partly an outer casing piece 22. The threaded part is in the inner
ende utformet med en innadrettet flens 23 for samvirke med en vinkelboyet spennring 25 samt i den ytre ende utformet med en utadrettet flens 24, som er beregnet på å ligge an mot mantel-stykkets ytre ende for å presse dette mot basisplaten 1 når spennringens skruer 8 trekkes til. end designed with an inward-directed flange 23 for cooperation with an angle-bent clamping ring 25 and at the outer end designed with an outward-directed flange 24, which is designed to rest against the outer end of the mantle piece in order to press this against the base plate 1 when the clamping ring screws 8 is drawn to.
Den i fig. 4 viste utforelsesform avviker fra den i fig. 3 men hensyn til lampehoIderens 4 og spennringens 35 utformning, som i dette tilfelle er utfort i ett og samme stykke. The one in fig. The embodiment shown in 4 differs from that in fig. 3 but taking into account the design of the lamp holder 4 and the clamping ring 35, which in this case is made in one and the same piece.
Tegningen og de dertil -horende beskrivelsesavsnitt er selvsagt The drawing and the accompanying description sections are of course
bare beregnet å å anskueliggjøre oppfinnelsens idé. Hva de-taljene angår, kan armaturen varieres betydlig innenfor oppfinnelsens ramme. Således kan den ovenfor omtalte, enhetlige spennring erstattes av to eller flere separate spennklor. Videre kan mantelstykket og basisplaten i utfdreisen ifolge fig. 4 utfores i ett stykke, og kun gjengedelen utfores separat fra basisplaten. Ytterligere er det-mulig å feste lampeholderen i spennringen istedenfor i basisplaten. intended only to illustrate the idea of the invention. As far as the details are concerned, the fixture can be varied significantly within the framework of the invention. Thus, the uniform clamping ring mentioned above can be replaced by two or more separate clamping claws. Furthermore, the casing piece and the base plate in the output travel according to fig. 4 is made in one piece, and only the threaded part is made separately from the base plate. Furthermore, it is possible to attach the lamp holder to the clamping ring instead of to the base plate.
Når armaturen er beregnet på å festes til en boks, kan basisplaten utgjore selve boksen. When the luminaire is intended to be attached to a box, the base plate can form the box itself.
