Description

Oppfinnelsen angår en utbalansert bærearm fbr f.eks. lampe, lupe eller lignende, omfattende to med hverandre leddforbundne armparalleilogrammer som hvert består av minst to hule stenger som ved begge ender er svingbart f orbundetmed en leddel, hvor en stang i hvert armparallellogram er fjærbelastet til en leddel ved hjelp av minst ett trykkfjærende element som med den ene ende ligger an mot et fast anlegg inn i den hule stang og er fullstendig opptatt i denne, og med den andre ende ligger an mot et i stangen glidbart legeme som samvirker med leddelene. The invention relates to a balanced support arm fbr e.g. 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 link at both ends, where a rod in each arm parallelogram is spring-loaded to a link by means of at least one compression spring element which with one end rests against a fixed installation in the hollow rod and is completely absorbed in this, and with the other end rests against a body that can slide in the rod and cooperates with the joint parts.

Fra britisk patentskrift nr. 813-721 er det kjent en bærearm med bare ett armparallellogram hvor en trykkfjær i en av parallellogrammets stenger, hvilken fjær med den andre ende ligger an mot et glidbart legeme som utenfor stangen er forsynt med en rulle som ruller på en krum kamflate av leddelen. Med en slik bærearm kan det oppnås utbalansering innenfor et begrenset foldeområde, men de utvendig anordnede kraftoverføringsdeler er tilgjengelige for beskadigelse og tilsmussing. From British patent document no. 813-721, a support arm with only one arm parallelogram is known, where a pressure spring in one of the bars of the parallelogram, which spring rests with the other end against a sliding body which, outside the bar, is provided with a roller that rolls on a curved cam surface of the joint. With such a support arm, balancing can be achieved within a limited folding area, but the externally arranged power transmission parts are accessible to damage and soiling.

Hensikten med oppfinnelsen er å unngå disse, ulemper. The purpose of the invention is to avoid these disadvantages.

Dette oppnås ifølge oppfinnelsen ved at det glidbare legeme, f.eks. av nylon, ligger an mot den ene ende av en stiv forbindelsesdel hvis andre ende er svingbart lagret i leddelen. This is achieved according to the invention by the sliding body, e.g. of nylon, rests against one end of a rigid connecting part whose other end is pivotally stored in the link part.

Den sti \e forbindelsesdel kan i den ende som er lagret The sti \e connection part can at the end which is saved

i leddelen være utformet som en totindet gaffel eller et øye som.er lagret på en lagertapp i leddelen, og gaffelen eller øyet kan alternativt ha en avlang åpning på tvers av forbindelsesdelens lengderetning og lagertappen kan ha et motsvarende tverrsnitt, slik at under bærearmens svingning forflyttes det fjærende elements angrepspunkt på leddelen fra den ene side av gaffelen eller øyet til den andre. in the joint part be designed as a two-pronged fork or an eye which is supported on a bearing pin in the joint part, and the fork or eye can alternatively have an elongated opening across the longitudinal direction of the connecting part and the bearing pin can have a corresponding cross-section, so that during the swing of the support arm, the the spring element's point of attack on the joint from one side of the fork or eye to the other.

To utførelseseksempler på oppfinnelsen skal nedenfor forklares nærmere under henvisning til tegningen. Fig. 1 viser et sideriss av en arbeidslampe med en bærearm ifølge oppfinnelsen. Two embodiments of the invention will be explained in more detail below with reference to the drawing. Fig. 1 shows a side view of a work lamp with a support arm according to the invention.

Fig. 2 viser i sideriss og devis i snitt det midtre Fig. 2 shows the middle section in side view and diagram

ledd av bærearmen på fig. 1 i forstørret målestokk. joint of the support arm in fig. 1 on an enlarged scale.

Fig. 3 viser i sideriss og forstørret målestokk en Fig. 3 shows in side view and enlarged scale one

annen utførelsesform av forbindelsesdelen og dens lagring i leddelen. another embodiment of the connecting part and its storage in the joint part.

Bærearmen ifølge utførelseseksemplet består av to med hverandre leddforbundne armparallellogrammer 1,2,3,4'resp. 4,5»6,7»bestående av leddelen 1 og 4 og hule stenger 2 og 4 The support arm according to the design example consists of two articulated arm parallelograms 1,2,3,4'resp. 4.5"6.7" consisting of link part 1 and 4 and hollow rods 2 and 4

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 8 for svingbar lagring av bærearmen i en bord- eller veggbeholder som ikke er vist på tegningen. respectively the joint parts 4 and 7 and hollow rods 5 and 6, pivotally connected by bolts. The link 1 carries a lampshade 9 and the link 7 has an axle pin 8 for pivotable storage of the support arm in a table or wall container which is not shown in the drawing.

Inn i den hule stang 3 er som vist på fig. 2 festet med den ene ende (ikke vist) av en skruestrekkfjær 10 hvis anre ende er haket sammen med den ende av enibrbindelsesdel 12 i form av et stykke ståltråd hvis ender er krokformet. Den andre ende av forbindelsesdelen 13 er haket inn i enden av stangen 2. Det er klart at utformingen av befestigelsen av denne fbrbindelsesdel kan være mangeartet bare den tåler strekkpåkjenning og over-fører strekkraften til det riktige angrepspunkt i leddelen 4. Into the hollow rod 3 is, as shown in fig. 2 attached with one end (not shown) of a screw tension spring 10, the other end of which is hooked together with the end of the unit connecting part 12 in the form of a piece of steel wire whose ends are hook-shaped. The other end of the connecting part 13 is hooked into the end of the rod 2. It is clear that the design of the fastening of this connecting part can be varied as long as it withstands tensile stress and transfers the tensile force to the correct attack point in the link part 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 3, f.eks. av nylon. 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 3, e.g. of nylon.

Utbalansering av det andre armparallellogram 4,5,6,7 skjer ved hjelp av en skruetrykkfjær 13 hvis ene ende ligger an mot Balancing of the second arm parallelogram 4,5,6,7 takes place by means of a screw pressure spring 13, one end of which rests against

et på tegningen ikke vist anlegg mens den andre ende bærer a facility not shown in the drawing while the other end carries

et lett glidbart legeme 15, f.eks. av nylon, på en tapp 16 og i den and^re enden har en hul lagerflate 17 for anlegg av den ehe .ende avforbinåelsesdelen 14 hvis andre ende har form av en totindet gaffel 19 som er lagret på en lagertapp 18 i leddelen 4. an easily sliding body 15, e.g. of nylon, on a pin 16 and at the other end has a hollow bearing surface 17 for installation of the connecting part 14, the other end of which is in the form of a two-pronged fork 19 which is stored on a bearing pin 18 in the link part 4.

For å øke utbalanseringsmomentet kan som vist på' fig. 3 den totindede gaffel 119 i enden avforbindelsesdelen 14'være bred for anlegg mot to ved siden av hverandre liggende lagertapper 18, eller en bred lagertapp som vist med strekede linjer på fig. 3-På denne måte flyttes fjærenes a'ngrepspunkt fra den ene To increase the balancing torque, as shown in fig. 3, the two-pronged fork 119 at the end of the connecting part 14' must be wide for abutment against two side-by-side bearing pins 18, or a wide bearing pin as shown with dashed lines in fig. 3-In this way, the point of attack of the springs is moved from one

tinden av gaffelen til den andre..'the tip of the fork of the other..'
