Abstract

Utbalansert bærearm for f.eks. lampe, lupe eller lignende.Balanced support arm for e.g. lamp, magnifying glass or similar.

Description

Oppfinnelsen angår en utbalansert bærearm for f.eks.lampe, lupe eller lignende, omfattende to med hverandre leddforbundne armparallellogrammer som hvert består av minst to hule stenger som ved begge ender er svingbart forbundet med en leddel, hvor en stang i hvert armparallellogram er fjærbelastet i forhold til en leddel ved hjelp av minst ett strekkfjærende element som med den ene ende er festet inne i den hule stang og fullstendig opptatt i denne, og den andre ende er forbundet med et i stangen glidbart legeme som er forbundet med leddelen. The invention relates to a balanced support arm for e.g. a lamp, magnifying glass or the like, comprising two articulated arm parallelograms each of which consists of at least two hollow rods which are pivotably connected to a joint at both ends, where one rod in each arm parallelogram is spring-loaded in relation to a link part by means of at least one tensile spring element which is fixed with one end inside the hollow rod and completely absorbed in it, and the other end is connected to a body which can slide in the rod and which is connected to the link part.

Fra britisk patentskrift nr. 659-561 er det kjent en bærearm med bare ett armparallellogram hvor en strekkfjær inne i en av parallellogrammets stenger er forbundet med dets to led-deler, slik at det oppnås utbalansering innenfor et begrenset foldeområde. From British patent document no. 659-561, a support arm with only one arm parallelogram is known, where a tension spring inside one of the parallelogram's rods is connected to its two link parts, so that balancing is achieved within a limited folding area.

Hensikten med oppfinnelsen er å tilveiebringe en bærearm av den innledningsvis nevnte art som gir tilfredsstillende utbalansering innenfor et vesentlig større foldeområde. The purpose of the invention is to provide a support arm of the type mentioned at the outset which provides satisfactory balancing within a significantly larger folding area.

Dette oppnås ifølge oppfinnelsen ved at det glidbare legeme f.eks. av nylon, er svingbart forbundet med den ene ende av en forbindelsesdel som rager ut gjennom en sliss i stangen og hvis andre ende er svingbart forbundet med leddelen eller med den parallelt forløpende stang i armparallellogrammet. This is achieved according to the invention by the sliding body e.g. of nylon, is pivotally connected to one end of a connecting part which protrudes through a slot in the rod and whose other end is pivotally connected to the link part or to the parallel running rod in the arm parallelogram.

To utførelseseksempler på oppfinnelsen skal nedenfor Two embodiment examples of the invention shall be given below

forklares nærmere under henvisning til tegningen. is explained in more detail with reference to the drawing.

Fig. 1 viser et sideriss av en arbeidslampe med en Fig. 1 shows a side view of a work lamp with a

bærearm ifølge oppfinnelsen. support arm according to the invention.

Fig. 2 viser i sideriss og delvis i snitt det nedre Fig. 2 shows the lower section in side view and partly in section

ledd av bærearmen på fig. li forstørret målestokk. joint of the support arm in fig. li enlarged scale.

Fig. 3 viser på samme måte det midtre ledd i bære- Fig. 3 shows in the same way the middle link in the carrier

armen på fig. 1. the arm of fig. 1.

Bærearmen ifølge utførelseseksemplet består av to med hverandre leddforbundne armparallellogrammer 1,2,3,4 resp. 4,5S 6,7 bestående avleddelene 1 og 4 og hule stenger 2 og 3 resp. leddelene 4 og 7 og hule stenger 5 og 6, svingbart forbundet med bolter. Leddet 1 bærer en lampeskjerm 9 og leddet -7 har en akseltapp 9 for svingbart lagring av bærearmen i en bord- eller veggholder som ikke er vist på tegningen. The support arm according to the design example consists of two articulated arm parallelograms 1,2,3,4 resp. 4,5S 6,7 consisting of the secondary parts 1 and 4 and hollow rods 2 and 3 resp. the joint parts 4 and 7 and hollow rods 5 and 6, pivotally connected by bolts. The joint 1 carries a lampshade 9 and the joint -7 has an axle pin 9 for pivotable storage of the support arm in a table or wall holder which is not shown in the drawing.

Inne i den hule stang 3 er som vist på fig. 3, festet med den ene ende (ikke vist) av en skruestrekkfjær 10 hvis andre ende er haket sammen med den ene ende av ehforbindelsesdel 12 Inside the hollow rod 3 is, as shown in fig. 3, fixed with one end (not shown) of a screw tension spring 10, the other end of which is hooked together with one end of the connecting part 12

i form av et stykke ståltråd hvis ender er krokformet. Den andre ende av forbindelsesdelen 12 er haket inn i enden av stangen 2. Det er klart at utformingen og befestigelsen av denne forbindelsesdel kan være mangeartet bare den tåler strekk-påkjenning og overfører strekkraften til det riktige angreps-punkt i leddelen 4. For å minske friksjonen i forbindelsen mellom fjæren 10 og forbindelsesdelen 12 er det anordnet et lett glidbart legeme 11 inne i den hule stang 35 f.eks. av nylon. in the form of a piece of steel wire whose ends are hook-shaped. The other end of the connecting part 12 is hooked into the end of the rod 2. It is clear that the design and fastening of this connecting part can be varied as long as it withstands tensile stress and transfers the tensile force to the correct point of attack in the link part 4. In order to reduce the friction in the connection between the spring 10 and the connecting part 12, an easily sliding body 11 is arranged inside the hollow rod 35 e.g. of nylon.

Fig. 2 viser i detalj det nedre ledd hvor det inne i den hule stang 5 er festet den ene ende (ikke vist) av en skruestrekkfjær 13, hvis andre ende inne i stangen er hektet på Fig. 2 shows in detail the lower link where one end (not shown) of a screw tension spring 13 is fixed inside the hollow rod 5, the other end of which inside the rod is hooked on

et lett-glidbart legeme 15 f.eks., av nylon som har en hake 16--som rager ut gjennom en langsgående sliss 17 i stangen 5-Forbindelsesdelen 14 har form av en U-formet ståltrådbøyle an easy-sliding body 15, for example, of nylon which has a hook 16--which protrudes through a longitudinal slot 17 in the rod 5-The connecting part 14 is in the form of a U-shaped steel wire hoop

hvis steg er hektet på haken 16 og hvis frie ender er bøyet inne over mot hverandre og lagret i huller 18 i leddelen 7- whose step is hooked on the hook 16 and whose free ends are bent inside towards each other and stored in holes 18 in the joint part 7-

Det er klart at bærearmen også kan ha to forbindelses-deler som vist på fig. 2 eller som vist på fig. 3- It is clear that the support arm can also have two connecting parts as shown in fig. 2 or as shown in fig. 3-
