Opfindelsen angår en afbalanceret bærearm, eksempelvis for en lampe eller en lup, og som omfatter to med hinanden ledforbundne armparallellogrammer, der hvert består af mindst to hule stænger, der ved hver ende er svingeligt forbundet med 5 en leddel, og hvoraf en stang i hvert armparallellogram er fjederbelastet i forhold til en leddel ved hjælp af mindst en trækfjeder, hvis ene ende er fastgjort indvendigt i den hule stang og er fuldstændigt optaget i denne, og hvis anden ende er forbundet med et i stangen glideligt organ, f.eks. af nylon, 10 der er forbundet med leddelen.The invention relates to a balanced support arm, for example for a lamp or a magnifier, and comprising two interconnected arm parallelograms, each consisting of at least two hollow bars pivotally connected at each end to a hinge member, and of which one rod in each arm parallelogram is spring loaded with respect to a link member by means of at least one tension spring, one end of which is secured internally to the hollow rod and is fully accommodated therein and the other end of which is connected to a slidable member, e.g. of nylon, 10 connected to the articulation member.

Fra tysk patentskrift nr. 908 643 kendes en lampe med en bærearm med to med hinanden ledforbundne armparallelogrammer, hvormed der opnås afbalancering indenfor et betydeligt svingningsområde, men denne afbalancering sker ved hjælp af udvendige 15 fjedre, således at bærearmen er udsat for tilsmudsning og be skadigelse af de kraftoverførende dele, hvorfor bærearmen er dårligt egnet til anvendelse både i et miljø, hvor den er udsat for hårdhændet behandling, f.eks. i værksteder og i et sterilt miljø, f.eks. i hospitaler.German Patent Specification No. 908 643 discloses a lamp having a support arm with two interconnected arm parallelograms, which achieves balancing within a significant oscillation range, but this balancing is done by external 15 springs, so that the support arm is exposed to dirt and damage. of the power transmitting parts, why the carrier arm is poorly suited for use both in an environment where it is subjected to harsh treatment, e.g. in workshops and in a sterile environment, e.g. in hospitals.

20 Det er opfindelsens formål at anvise en bærearm af den foran nævnte art, der er således udformet, at der både opnås en tilfredsstillende afbalancering inden for et betydeligt svingningsområde og beskyttelse af de kraftoverførende dele mod beskadigelse og forurening, og dette er ifølge opfindelsen opnået 25 ved, at det giidelige organ er svingeligt forbundet med den ene ende af et forbindelsesorgan i form af et tyndt, langstrakt metallegeme, såsom et stykke ståltråd med ombukkede ender, der rager ud gennem en slids i stangen, og hvis anden ende er svingeligt forbundet med leddelen eller med den i armparallellogram-30 met parallelt forløbende stang.It is an object of the invention to provide a support arm of the aforementioned kind, which is designed to achieve both a satisfactory balancing within a considerable oscillation area and protection of the power transmitting parts against damage and pollution, and this is achieved according to the invention. in that the movable member is pivotally connected to one end of a connecting member in the form of a thin elongated metal body, such as a piece of steel wire with bent ends projecting through a slot in the rod, the other end of which is pivotally connected to the hinge member or with the bar extending parallel to the arm parallelogram.

Ved denne udformning opnås et meget stort svingningsområde som følge af, at forbindelsesorganet rager ud gennem den til siden vendende slids og er udformet som et tyndt, langstrakt legeme, der tillader, at hvert armparallellograms to arme i svingnings-35 områdets to yderstillinger kan ligge ganske nær ved hinanden.In this embodiment, a very large oscillation area is obtained because the connector extends through the lateral slit and is formed as a thin elongated body which allows each arm of the arm parallelogram in the two outer positions of the oscillation region to be quite close to each other.

Samtidig ligger de kraftoverførende dele beskyttede i den hule stang.At the same time, the power transmitting parts are protected in the hollow rod.

To udførelseseksempler for en bærearm ifølge opfindelsen forklares nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser set fra siden en arbejdslampe med en bærearm 5 ifølge opfindelsen, fig. 2 viser set fra siden og delvis i snit det nedre led af bærearmen ifølge fig. 1 i større målestok, og fig. 3 viser på samme måde det midterste led af bærearmen ifølge fig. 1.Two embodiments of a support arm according to the invention are explained in more detail below with reference to the drawing, in which fig. 1 is a side view of a working lamp with a support arm 5 according to the invention; FIG. 2 is a side view, partly in section, of the lower link of the support arm of FIG. 1 on a larger scale; and FIG. 3 similarly shows the middle link of the support arm according to FIG. First

10 Den viste bærearm består af to med hinanden ledforbundne armparallellogrammer 1, 2, 3, 4 henholdsvis 4, 5, 6, 7, der er dannet af leddelene 1 og 4 og af hule stænger 2 og 3, henholdsvis af leddelene 4 og 7 og af hule stænger 5 og 6, og som er svingeligt forbundet med bolte. Leddet 1 15 bærer en lampeskærm 9, og leddet 7 har en akseltap 9 til svingelig lejring af bærearmen i en ikke vist bord- eller vægholder.The supporting arm shown consists of two interconnected arm parallelograms 1, 2, 3, 4 and 4, 5, 6, 7, respectively, formed by the link parts 1 and 4 and of hollow bars 2 and 3, respectively of the link parts 4 and 7 and of hollow bars 5 and 6 and pivotally connected to bolts. The link 1 15 carries a lamp shade 9 and the link 7 has a shaft pin 9 for pivotally bearing the support arm in a table or wall holder not shown.

Indvendigt i den hule stang 3 er som vist i fig. 3 anbragt en skrueformet trækfjeder 13, hvis ene ikke viste ende er 20 fastgjort til stangen, og hvis anden ende er fasthaget til den ene ende af et forbindelsesorgan 12 i form af et stykke ståltråd med krogformede enheder. Den anden ende af forbindelsesorganet 12 er fasthaget til enden af stangen 2. Udformningen og fastgørelsen af forbindelsesorganet kan 25 ske på mange måder, når blot det tåler trækpåvirkning og vil overføre trækkraften til det rigtige angrebspunkt på leddelen 4. For at mindske friktionen mellem fjederen 10 og forbindelsesorganet 12 er der indvendigt i stangen anbragt et let glideligt organ 11 f.eks. af nylon.Inside the hollow rod 3 is shown in FIG. 3, a helical tension spring 13 is provided, one end of which is not shown 20 attached to the rod and the other end of which is fixed to one end of a connecting member 12 in the form of a piece of steel wire with hook-shaped units. The other end of the connector 12 is secured to the end of the rod 2. The design and attachment of the connector 25 can be accomplished in many ways as long as it can withstand drag and will transfer the traction to the correct point of attack on the link member 4. To reduce friction between the spring 10 and the connecting member 12 is provided with a slidable member 11 inside the rod, e.g. of nylon.

30 Fig. 2 viser en del af det nedre led 7, hvor der indvendigt i den hule stang 5 er fastgjort den ene - ikke viste - endeFIG. 2 shows a part of the lower link 7 where the inside - of the hollow rod 5 - is attached to the one - not shown - end
