Description
Anordning ved innstillbar bærearm for elektriske lamper. Device with adjustable support arm for electric lamps.
Denne oppfinnelse vedrører en anordning ved vinkelforstillbare parallell-stang-bærearmer for elektriske lamper, hvor der mellom punkter på de to parallelle om hver sin svingetapp forstillbare stenger er utspent i en liten vinkel med disses retning en strekkfjær, hvis lengde og spennkraft er avhengig av bærearmens vinkelstilling. This invention relates to a device for angle-adjustable parallel-rod support arms for electric lamps, where between points on the two parallel adjustable rods about each pivot pin, a tension spring is stretched at a small angle with their direction, the length and tension force of which is dependent on the support arm angular position.
Ved sådanne bærearmer sørger man for With such support arms, care is taken to
at armen kan bli stående i enhver gitt inn-stilling. Dette kan gjøres f. eks. ved å ut-føre en eller flere av de fire tapper i stang-parallellogrammet med ekstra friksjon mot dreining av vedkommende stang eller stenger. En ulempe er ellers at spennfjæren som ligger åpen, er utsatt for støv og for ved hårdhendt berøring å meddeles util-siktet en forandret spennkraft så at bærearmen ikke lenger blir stående i sine gitte innstillinger. Dertil kommer at den åpent liggende fjær gir bærearmen et lite til-talende utseende, særlig da det gjerne for-langes at armene som helhet bare skal vise glatte, polerte metallflater som lett kan holdes rene og blanke. that the arm can remain in any given setting. This can be done e.g. by carrying out one or more of the four pins in the rod parallelogram with extra friction against rotation of the respective rod or rods. Another disadvantage is that the tension spring, which is open, is exposed to dust and, when touched with a hard hand, inadvertently changes the tension force so that the support arm no longer remains in its given settings. In addition, the open spring gives the support arm an unattractive appearance, especially as it is often required that the arms as a whole should only show smooth, polished metal surfaces that can easily be kept clean and shiny.
Oppfinnelsen tar hensyn til alle disse The invention takes all of these into account
forhold derved at strekkfjæren er innesluttet i et par teleskopisk i hinannen bevegelige rør som ikke alene beskytter den mot forstrekning og støv, men også motvirker og skjuler rustdannelse foruten at den hin-drer at fjærene kan hukes av uten bruk av verktøy. condition whereby the tension spring is enclosed in a pair of telescopically movable tubes that not only protect it from pre-stretching and dust, but also counteract and hide rust formation, besides preventing the springs from being able to be hacked off without the use of tools.
1 er den vanligvis vertikale bæretapp 1 is the usually vertical support pin
for bærearmen, ved hjelp av hvilken denne kan festes svingbart til en vegg eller annen fastliggende del. På tappen 1 sitter en liten for the support arm, with the help of which this can be attached pivotably to a wall or other fixed part. On pin 1 is a small one
knekt 2 med to tapper 3 og 4 for den ene ende av de parallelle stenger 5 resp. 6, hvis andre ende ved tapper 7 resp. 8 er svingbart festet til en vinkel 9 på hvis tredje tapp 10 lampen 11 henger direkte eller in-direkte. jack 2 with two pins 3 and 4 for one end of the parallel rods 5 or 6, whose other end at pins 7 or 8 is pivotably attached to an angle 9 on whose third pin 10 the lamp 11 hangs directly or indirectly.
Mellom punkter på de to stenger 5 og 6 f. eks. mellom tappen 3 og en tapp 12 på stangen 6 er således utspent en strekkfjær 13 som danner en liten vinkel med stenge-nes retning slik at fjæren stadig søker å svinge lampen resp. stengene oppover om de to punktene 3, 4 av parallellogrammet 3, 4, 8, 7 i en bestemt retning. Denne anordning er alminnelig kjent. Between points on the two rods 5 and 6, e.g. between the pin 3 and a pin 12 on the rod 6, a tension spring 13 is thus stretched which forms a small angle with the direction of the rods so that the spring constantly seeks to swing the lamp resp. the bars upwards about the two points 3, 4 of the parallelogram 3, 4, 8, 7 in a certain direction. This device is generally known.
Ifølge oppfinnelsen er nu fjæren 13 nu innesluttet i to teleskopisk i hinannen bevegelige rør 14 og 15 som er ført så tett frem til fjærens respektive festeskruer 3, 12 og her er slik innsnevret og fastholdt på fjærendene at fjæren ikke kan hukes av festeskruene uten bruk av verktøy. På denne måte vil ikke alene fjæren beskyttes mot støv og rustdannelse men «teknisk in-teresserte» (f. eks. pasienter på sykehus) som føler trang til å «klusse» med lampeholderen, vil også hindres fra å deformere fjæren, hekte den av eller endog miste den, hvorved lampeholderen kunne bli ødelagt. According to the invention, the spring 13 is now enclosed in two telescopically movable tubes 14 and 15 which are brought so close to the spring's respective fastening screws 3, 12 and here it is so narrowed and held on the spring ends that the spring cannot be bent by the fastening screws without the use of tool. In this way, not only will the spring be protected against dust and rust, but "technically interested" (e.g. patients in hospitals) who feel the urge to "fuss" with the lamp holder, will also be prevented from deforming the spring, hooking it off or even lose it, whereby the lamp holder could be destroyed.
