Abstract
Description
Foreliggende oppfinnelse omfatter en elektrisk belysningsarmatur med blender, slik det nærmere er beskrevet i innledningen til patentkrav 1. Oppfinnelsen omfatter videre en framgangsmåte for framstilling av en slik blender i samsvar med innledningen til det selvstendige framgangsmåtekravet. The present invention comprises an electric lighting fixture with an aperture, as described in more detail in the introduction to patent claim 1. The invention further comprises a method for producing such an aperture in accordance with the introduction to the independent method claim.
Bakgrunn Background
Blender for belysningsarmaturer framstilles enten som homogene enheter ved f.eks. sprøyting i plast, eller settes sammen ved hjelp av spiler forsynt med spor, og som siden hektes i hverandre. Disse sammenføyningsmetoder gir vanligvis en svært ustabil konstruksjon. En annen ulempe med dagens blendere er at passende verktøy er svært kostbare. Dessuten blir produksjonen vanskelig og kostbar å omstille til andre produkt-typer hhv. størrelser. Festingen av blenderen skjer enten ved at blenderen legges på en hyllekant i armatur-ramma eller ved at blenderen holdes fast ved hjelp av holdere. Shutters for lighting fittings are produced either as homogeneous units by e.g. spraying in plastic, or assembled using spindles equipped with grooves, which are then hooked into each other. These joining methods usually result in a very unstable construction. Another disadvantage of today's blenders is that suitable tools are very expensive. In addition, the production becomes difficult and expensive to convert to other product types or sizes. The attachment of the blender takes place either by placing the blender on a shelf edge in the fitting frame or by holding the blender firmly using holders.
Fra DE-A-2916331 er det kjent en blender i samsvar med den innledende delen av krav 1. Formålet med denne blenderen var å senke produksjonskostnadene og unngå svakheten med en konstruksjon omfattende løse langs- og tverrgående deler. Løsningen er en blender i en del som er stanset ut av et emne og bøyd til en skjerm som omfatter bare tverrgående ribber og side- langsgående sammenføyningspunkter. From DE-A-2916331 there is known a blender according to the preamble of claim 1. The purpose of this blender was to lower production costs and avoid the weakness of a construction comprising loose longitudinal and transverse parts. The solution is a one-piece blender punched out of a blank and bent into a screen that includes only transverse ribs and side-longitudinal joining points.
Fra US-A-3016997 er det tidligere kjent en gitterlignende skjerm-struktur, hvor ribbe-formasjonen i en retning er hovedsakelig den samme som de i den andre retningen. En slik struktur er begrenset av forskjellige beskyttelses-elementer. From US-A-3016997 there is previously known a lattice-like screen structure, where the rib formation in one direction is substantially the same as those in the other direction. Such a structure is limited by various protection elements.
Formål Purpose
Formålet med foreliggende oppfinnelse er derfor å framskaffe en elektrisk belysnings-armatur med en billig, men samtidig fastgjort blender, som valgfritt kan lages i metall eller plast, som ikke har løse deler og som videre stiller små krav til tilpasnings-nøyaktighet ved montering og bruk. Oppfinnelsen gjelder videre å frambringe en fordelaktig og formålstjenlig metode for å framstille en slik blender. The purpose of the present invention is therefore to provide an electric lighting fixture with a cheap, but at the same time fixed aperture, which can optionally be made in metal or plastic, which has no loose parts and which also makes little demands on the accuracy of fit during assembly and use . The invention further relates to producing an advantageous and expedient method for producing such a blender.
Oppfinnelse Invention
For å oppnå dette defineres en elektrisk belysnings-armatur med en blender i samsvar med oppfinnelen ved de særtrekk, som beskrives i den karakteriserende delen av patentkrav 1. Karakteriserende for framgangsmåten er de særtrekk, som framgår av det første framgangsmåtekravet. In order to achieve this, an electric lighting fixture with an aperture in accordance with the invention is defined by the special features described in the characterizing part of patent claim 1. Characterizing the method are the special features that appear in the first method claim.
Oppfinnelsen beskrives nærmere i det etterfølgende med henvisning til vedlagte figurer, der The invention is described in more detail below with reference to the attached figures, where

fig. 5 viser et snitt av blenderen sett ovenfra, mens fig. 5 shows a section of the blender seen from above, while
fig. 6 viser et metallstykke til en blender i samsvar med oppfinnelsen. fig. 6 shows a metal piece for a blender in accordance with the invention.
I fig. 1 vises i sin helhet en elektrisk belysnings-armatur med en blender i samsvar med oppfinnelsen. Armaturen oppviser eksempelvis i endene anordnete lysrørholdere 2, og mellom disse er anordnet lysrør 3, som omgis av en langstrakt, skål- og renneformet reflektor 4 av f.eks. metall, hvis nedoverrettete langsider nærmest er awinklet f.eks. horisontalt utover i form av liv 5 og siden skrått oppover og utover i form av gjennomgående festeflenser 6. In fig. 1 shows in its entirety an electric lighting fixture with a blender in accordance with the invention. The fixture has, for example, fluorescent tube holders 2 arranged at the ends, and fluorescent tubes 3 are arranged between these, which are surrounded by an elongated, bowl- and trough-shaped reflector 4 of e.g. metal, whose downward-directed long sides are almost awinkled, e.g. horizontally outwards in the form of a web 5 and laterally obliquely upwards and outwards in the form of continuous fastening flanges 6.
Blenderen 7 i samsvar med oppfinnelsen skal anordnes i reflektoråpningen 8, og oppviser for dette formål gjennomgående festelister 9 som er plassert langs sidene, og som fortrinnsvis er anordnet i samme plan og hvis hoveddeler 10 skal snu mot hverandre, og ferdigmontert skal ligge planparallelt mot livet 5. Hoveddelene går utover mot flensene 6 motsvarende avvinklete dekk-flenser 11, som også skal ligge plan-parallelt mot flensene 6 og skjøtes på disse enten fra armaturens ene ende eller fortrinnsvis rett underfra, hvor utstansete holdeknaster 12 fra flensene 11 skal hektes til flensene 11, eventuelt med kneppvirkning, som utnytter materialet hhv. struktur-elastisiteten i minst en av delene. The blender 7 in accordance with the invention is to be arranged in the reflector opening 8, and for this purpose exhibits continuous fixing strips 9 which are placed along the sides, and which are preferably arranged in the same plane and whose main parts 10 are to face each other, and when fully assembled are to lie plane-parallel to the waist 5. The main parts extend outwards towards the flanges 6 corresponding to the angled cover flanges 11, which must also lie plane-parallel to the flanges 6 and be joined to these either from one end of the fixture or preferably directly from below, where punched retaining lugs 12 from the flanges 11 are to be hooked to the flanges 11, possibly with a snap action, which utilizes the material or the structural elasticity in at least one of the parts.
Tverr-ribber 13 strekker seg på tvers mellom hoveddelen 10 fortrinnsvis med lik innbyrdes avstand. Tverr-ribbene 13 er fortrinnsvis utformet i ett stykke med hoved delene 10 og flensene 11. Disse tverr-ribber er fortrinnsvis V-formet i profil ved dannelse av bein 14, hvor beinas felles bunn 15 fortrinnsvis ligger i samme plan som hoveddelene 10, og hvor tverr-ribbens symmetriplan med et bein på hver side er rettet i rett vinkel i forhold til planet for hoveddelene 10. Det kan også tenkes bøyninger i forskjellige vinkler. Tverr-ribbenes ender 16 smalner hensiktsmessig av i rett eller avrundet form i retning mot tverr-ribbenes frie langsider, fortrinnnsvis følger den konturen av reflektorens 4 innside. Transverse ribs 13 extend transversely between the main part 10 preferably at an equal distance from each other. The transverse ribs 13 are preferably formed in one piece with the main parts 10 and the flanges 11. These transverse ribs are preferably V-shaped in profile when forming legs 14, where the common bottom 15 of the legs preferably lies in the same plane as the main parts 10, and where the plane of symmetry of the transverse rib with a leg on each side is directed at right angles to the plane of the main parts 10. It is also conceivable to bend at different angles. The ends 16 of the transverse ribs appropriately taper in a straight or rounded shape in the direction towards the free long sides of the transverse ribs, preferably following the contour of the inside of the reflector 4.
Tverr-ribbene er fortrinnsvis forbundet i midten ved en langsgående stag-ribbe 17, som fortrinnsvis også er V-formet i profil, hvor de frie langsidene kan være bøyd i retning mot hverandre i form av flenser 18, som kan gis en ekstra stagningsfunksjon og/eller holdefunksjon. Stagribba er nedsenket i tverr-ribbene 13, ikke helt ned til bunnen 15, men ligger fortrinnsvis med sin bunn 19 noen centimeter over. I det viste eksempel er tverr-ribbene og stagribben omtrent like høye, noe som innebærer at stagribben stikker opp et stykke ovenfor tverr-ribbene. Det kan tenkes at man lar stagribben(e)s profil slutte omtrent på samme niva som tverr-ribbene eller muligens også på et lavere nivå. The transverse ribs are preferably connected in the middle by a longitudinal strut rib 17, which is preferably also V-shaped in profile, where the free long sides can be bent in the direction of each other in the form of flanges 18, which can be given an additional stabilizing function and /or holding function. The stanchion is immersed in the transverse ribs 13, not all the way down to the bottom 15, but preferably lies with its bottom 19 a few centimeters above. In the example shown, the transverse ribs and the stay ribs are approximately the same height, which means that the stay ribs protrude a little above the transverse ribs. It is conceivable that the profile of the stay rib(s) ends approximately at the same level as the cross ribs or possibly also at a lower level.
For å holde fast stagribben, er tverr-ribbene eksempelvis i midten forsynt med V-formete utsparinger eller utstansinger 20, hvor sidekantene 21 til disse utsparingene med fordel oppviser utspring 22 ment for å gripe inn i f.eks.sliss-liknende åpninger 23 i stagribben, og så på innsiden av stagribben, bøyes til siden for på en slik måte å feste stagribben til tverr-ribbene, og støtte opp tverr-ribbene innbyrdes, og gi hele blenderen stivhet og torsjons-motstandskraft. For samme formål kan det stikke fram ei tunge 24 fra utsparingenes bunn 20, som skal gripe inn i f.eks. et firkantet hull 25 i stagribbens bunn, hvor tungene kan bøyes til siden, hhv. innside eller overside, etter inngripen. In order to hold the strut rib, the transverse ribs are, for example, provided in the middle with V-shaped recesses or cutouts 20, where the side edges 21 of these recesses advantageously have protrusions 22 intended to engage in, for example, slot-like openings 23 in the stay rib, and then the inside of the stay rib, is bent to the side in such a way as to attach the stay rib to the cross ribs, and support the cross ribs against each other, and give the whole blender rigidity and torsional resistance. For the same purpose, a tongue 24 can protrude from the bottom 20 of the recesses, which should engage in e.g. a square hole 25 in the bottom of the stay rib, where the tongues can be bent to the side, or inside or outside, after the intervention.
Det kan være spesielt fordelaktig, som vist i fig. 6, om det blender-stykket, og også emnet til en stagribbe, bøyes slik at tverr-ribbene og/eller stagribben før sammen-setning framviser beinpar-vinkler, som avviker fra motvarende vinkler i montert stand. På denne måten kan beina ved montering med en viss spenst eller strukturelastisitet, dvs. mot en viss fjærpåvirkning, tvinges inn i monteringsstilling, som langsgående sikrer fleksibilitet og garanterer stivhet. Dette oppnås spesielt ved at de nevnte beinpar presses sammen ved montering. It can be particularly advantageous, as shown in fig. 6, if the blender piece, and also the blank for a stay rib, is bent so that the transverse ribs and/or stay rib before assembly present leg-pair angles, which deviate from corresponding angles in the assembled state. In this way, the legs can be forced into the mounting position during assembly with a certain resilience or structural elasticity, i.e. against a certain spring influence, which longitudinally ensures flexibility and guarantees rigidity. This is achieved in particular by the aforementioned pairs of legs being pressed together during assembly.
Ved figur 6 vises eksempelvis et metall-plateemne som lett kan forsynes med nødvendige utstansinger, hvor utstansingsmønsteret lett og enkelt kan gjentas, slik at det oppnås valgfrie lengder. Alt som trengs etter utstansingen er bøyning av tverr-ribbene rundt hovedlinjene 26, og bøyning av sidelistene rundt bøyningslinjer 27, hvor man da eller seinere forsyner flensene 11 med uttak 12, som siden bøyes innover for å danne de beskrevne og viste festeorganene 12. Det er like enkelt å ta et tiltenkt emne for stagribbe, som er forsynt med utstansinger, og bøye dette emnet til en stagribbe, og siden anbringe dette på beskrevet måte i tverr-ribbene. Ettersom stagribben er åpen både oppover og i aksial- retning, er det lett å føre inn ett eller flere verktøy, som bøyer tverr-ribbenes utspring og tunger til siden, og inntil stagribbens innside, som er alt for å sette i stand og sette sammen en blender i samsvar med oppfinnelsen. Figure 6 shows, for example, a sheet metal blank that can easily be supplied with the necessary punches, where the punching pattern can easily and simply be repeated, so that optional lengths are obtained. All that is needed after punching out is bending of the cross ribs around the main lines 26, and bending of the side strips around bending lines 27, where one then or later provides the flanges 11 with outlets 12, which are then bent inwards to form the described and shown fastening means 12. it is just as easy to take an intended blank for stanchions, which is provided with cutouts, and bend this blank into a stanchion, and then place this in the described manner in the transverse ribs. As the strut rib is open both upwards and in the axial direction, it is easy to insert one or more tools, which bend the protrusions and tongues of the transverse ribs to the side, and up to the inside of the strut rib, which is all for setting up and assembling a blender in accordance with the invention.
Blenderen i samsvar med oppfinnelsen kan tilvirkes av metall, men også av plast, hvor det også kan tenkes en sammensveising av delene ved berøringspunktene utover den beskrevne sammenslutning av åpninger, utsparinger og i disse inngripende utspring og tunger. The blender according to the invention can be made of metal, but also of plastic, where it is also conceivable to weld the parts together at the points of contact beyond the described combination of openings, recesses and in these intervening protrusions and tongues.
Blenderen i samsvar med oppfinnelsen er også svært holdbar og motstandsdyktig mot vri- og bøyningspåkjenninger selv ved bruk av svært tynne metaller. The blender according to the invention is also very durable and resistant to twisting and bending stresses even when using very thin metals.
