Description

Anordning for feste av en elektrisk lysarmatur. Device for attaching an electric light fixture.

Foreliggende oppfinnelse angår en anordning for opphengning av belysningsut-styr fra en takboks e. 1. og er særlig bereg-net for anvendelse i forbindelse med belys-ningsutstyr som ønskes gitt en spesiell orientering i rommet, f. eks. lysstoffrør e. 1. hvis lengderetning i alminnelighet bestem-mes i hvert enkelt tilfelle i forhold ikke bare til rommets vegger, men også ofte til dets møblering eller andre forhold som avhenger av rommets bruk. The present invention relates to a device for hanging lighting equipment from a ceiling box e. 1. and is particularly intended for use in connection with lighting equipment that is desired to be given a special orientation in the room, e.g. fluorescent tubes e. 1. whose longitudinal direction is generally determined in each individual case in relation not only to the walls of the room, but also often to its furnishings or other conditions that depend on the use of the room.

Ved de opphengningsanordninger som hittil har vært brukt med feste i takboksen eller dens lokk har en slik orientering av belysningsutstyret vært vanskelig eller umulig å foreta nøyaktig. Takboksen anbringes under oppførelsen av huset, hvor-ved beliggenheten av de gjengede hull for feste av lokket er fastlagt allerede på dette tidlige tidspunkt. Ved at opphengnings-anordningen er innrettet til å forbindes fast med boksen eller lokket vil dens orientering være fastlagt i forhold til skruehullene i boksen slik at en etter-innstilling av belysningsutstyret ikke kan foretas. In the case of the suspension devices that have been used up to now with attachment to the ceiling box or its lid, such an orientation of the lighting equipment has been difficult or impossible to carry out accurately. The roof box is placed during the construction of the house, where the location of the threaded holes for attaching the lid is determined already at this early stage. As the suspension device is designed to be firmly connected to the box or the lid, its orientation will be fixed in relation to the screw holes in the box so that a readjustment of the lighting equipment cannot be carried out.

I henhold til oppfinnelsen er denne ulempe overvunnet ved at opphengnings-anordningen omfatter en bærebjelke for belysningsutstyret, som er utstyrt med klem-innretninger som kan gripe over kanten på lokket for koblingsboksen. Det er således mulig å orientere bærebjelken, og dermed selve belysningsutstyret helt fritt i forhold til skruehullene i takboksen, en fordel som kan utnyttes ikke bare ved den første lysinnstallasjon i rommet, men når som helst senere. According to the invention, this disadvantage is overcome by the suspension device comprising a support beam for the lighting equipment, which is equipped with clamping devices that can grip over the edge of the lid of the junction box. It is thus possible to orient the support beam, and thus the lighting equipment itself, completely freely in relation to the screw holes in the ceiling box, an advantage that can be used not only at the first lighting installation in the room, but at any time later.

For herunder å lette arbeidet med opp-hengningen av utstyret er bærebjelken i In order to facilitate the work with the suspension of the equipment, the support beam is in

henhold til oppfinnelsen hensiktsmessig ut-formet som en skinne med dobbelt om-bøyede ender således at en tversgående del på utstyret helt enkelt kan henges inn på disse ombøyede ender og festes i denne stilling idet vekten av utstyret opptas av en-dene, ikke bare under fastsettingen, men også varig. Herved oppnås den fordel at fastsettingen, f. eks. ved hjelp av skruer, kan foretas uten at skruene belastes og at disse skruer heller ikke senere trenger å oppta vekten av utstyret. according to the invention suitably designed as a rail with double-bent ends so that a transverse part of the equipment can simply be hung onto these bent ends and fixed in this position as the weight of the equipment is taken up by the ends, not only under the determination, but also lasting. This achieves the advantage that the determination, e.g. by means of screws, can be made without the screws being loaded and that these screws do not need to absorb the weight of the equipment later either.

På tegningen er det skjematisk vist en utførelsesform for en opphengningsanord-ning i henhold til oppfinnelsen. The drawing schematically shows an embodiment of a suspension device according to the invention.

Fig. 1 viser anordningen sett ovenfra Fig. 1 shows the device seen from above

og fig. 2 i snitt etter linjen II—II i fig. 1. and fig. 2 in section along the line II—II in fig. 1.

På tegningen betegner 1 er skinne-formet bærebjelke som ved hver ende er dobbelt ombøyet slik at det fremkommer endepartier 2 som kan bære en del 3 som hører til selve belysningsutstyret, som ikke er vist, eller kan festes til dette, f. eks. ved hjelp av anordninger som griper inn i hul-lene 4 i delen 3. Endepartiene 2 er innrettet for opptagelse av festeskruer 5 for delen 3. In the drawing, 1 denotes a rail-shaped support beam which is bent twice at each end so that end parts 2 appear which can carry a part 3 which belongs to the lighting equipment itself, which is not shown, or which can be attached to this, e.g. by means of devices that engage in the holes 4 in the part 3. The end parts 2 are designed to receive fastening screws 5 for the part 3.

Skinnen 1 er videre utstyrt med to klem-innretninger som hver består av et svakt vinkelformet stykke 6 med to festeskruer 7. Stykkene 6 er innrettet til å gripe over kanten av et bokslokk 8 av vanlig type med diametralt anbrakte hull 9 for skruer for feste av lokket til en takboks som ikke er vist. I delen 3 er det videre anordnet hull 10 tilsvarende festeskruene 7 for klem-innretningene således at disse The rail 1 is further equipped with two clamping devices, each of which consists of a slightly angled piece 6 with two fixing screws 7. The pieces 6 are arranged to grip over the edge of a box lid 8 of the usual type with diametrically arranged holes 9 for screws for fixing the lid of a roof box not shown. In part 3, holes 10 corresponding to the fastening screws 7 for the clamping devices are also arranged so that these

skruer blir tilgjengelige uten å måtte fjerne delen 3. Lokket er på vanlig måte forsynt screws become accessible without having to remove part 3. The lid is supplied in the usual way

med et sentralt hull 11 for de elektriske with a central hole 11 for the electrics
