Jacobsen A/S, Enebakkveien 117, Oslo 6, Norja-Norge(NO) (72) Jens Christian Krogsrud, Oslo, Norja-Norge(NO) (7M Berggren Oy Ab (5U) Tasapainotettu kannatinvarsi, esimerkiksi lamppua, luppia tai sentapaista varten - Utbalanserad bärarm, exe-mpelvis för lampa, lupp eller dyliktNorway-Norway (NO) 753611 (γΐ) Jac. Jacobsen A / S, Enebakkveien 117, Oslo 6, Norway-Norge (NO) (72) Jens Christian Krogsrud, Oslo, Norway-Norway (NO) (7M Berggren Oy Ab (5U) Balanced support arm, for example for a lamp, magnifying glass or similar - Utbalanserad bärarm, exe-mpelvis för lampa, lupp eller dylikt

Esillä oleva keksintö kohdistuu tasapainotettuun kannatinvarteen esimeriksi lamppua, luppia tai sentapaista varten, käsittäen kaksi toisiinsa nivelöityä varsisuunnikasta, joista kundikin muodostuu ainakin kahdesta ontosta tangosta, jotka ovat molemmissa päissään kääntyvästi yhdistetyt nivelosaan, jolloin kummankin varsisuunnikkaan tanko on jousikuormitettu nivelosaan nähden ainakin yhdellä vetojousielemen-tillä, joka on toisesta päästään kiinnitetty onton tangon sisään ja sijaitsee täysin tämän sisällä, ja joka on toisesta päästään yhdistetty tangossa liukuvaan kappaleeseen, joka on yhdistetty nivelosaan.The present invention is directed to a balanced support arm for, for example, a lamp, a magnifying glass or the like, comprising two articulated stems, each of which consists of at least two hollow rods pivotally connected at both ends to the articulated portion. which is fixed at one end inside the hollow rod and is located completely inside it, and which at the other end is connected to a sliding body in the rod, which is connected to the articulation part.

Brittiläisestä patentista n:o 659 561 tunnetaan kannatinvarsi, jossa on vain yksi varsisuunnikas, jossa suunnikkaan yhdessä tangossa oleva vetojousi on yhdistetty sen kahteen nivelosaan niin, että saavutetaan tasapainotus rajoitetun kääntöalueen sisällä.British Patent No. 659,561 discloses a support arm with only one arm parallelogram, in which a tension spring in one rod of the parallelogram is connected to its two articulated parts so as to achieve equilibrium within a limited turning range.

Esillä olevan keksinnön tarkoituksena on aikaansaada johdannossa mainittua tyyppiä oleva kannatinvarsi, joka antaa tyydyttävän tasapainotuksen huomattavasti suuremmalla kääntöalueella.The object of the present invention is to provide a support arm of the type mentioned in the introduction, which provides a satisfactory balance in a considerably larger swivel range.

61.743 Tämän saavuttamiseksi on keksinnölle tunnusomaista, että liukukappale, joka on esim. nailonia, on kääntyvästi yhdistetty tangossa olevan raon läpi ulottuvan yhdysosan toiseen päähän, jonka osan toinen pää on kääntyvästi yhdistetty nivelosaan tai varsisuunnikkaassa yhdensuuntaisena ulottuvaan tankoon.61.743 To achieve this, the invention is characterized in that a slider, e.g. nylon, is pivotally connected to one end of a connecting portion extending through a slot in the rod, the other end of which portion is pivotally connected to a hinge portion or a rod extending parallel to the stem parallelogram.

Kahta keksinnön suoritusesimerkkiä tullaan seuraavassa selostamaan lähemmin viitaten piirustukseen.Two embodiments of the invention will be described in more detail below with reference to the drawing.

Kuvio 1 esittää sivunäkymää keksinnön mukaisella kannatinvarrella varustetusta työvalaisimesta.Figure 1 shows a side view of a work light with a support arm according to the invention.

Kuvio 2 esittää osittain leikattua sivunäkymää kuvion 1 mukaisen kannatinvarren alaosasta suuremmassa mittakaavassa.Fig. 2 shows a partially sectioned side view of the lower part of the support arm according to Fig. 1 on a larger scale.

Kuvio 3 esittää samalla tavalla kuvion 1 mukaisen kannatinvarren keskiosaa.Fig. 3 similarly shows the central part of the support arm according to Fig. 1.

Suoritusesimerkin mukainen kannatinvarsi muodostuu kahdesta toisiinsa nivelöidystä varsisuunnikkaasta 1, 2, 3, 4 vast. 4, 5, 6, 7, käsittäen nivelosat 1 ja 4 ja ontot tangot 2 ja 3 sekä vastaavasti nivel-osat 4 ja 7 ja ontot tangot 5 ja 6, jotka ovat kääntyvästi yhdistetyt pulteilla. Nivelosa 1 kannattaa lämpun varjostinta 9 ja nivel-osassa 7 on akselitappi 9 kannatinvarren laakeroimiseksi kääntyvästi pöytä- tai seinäpitimeen, jota ei ole esitetty piirustuksessa.The support arm according to the exemplary embodiment consists of two articulated armrests 1, 2, 3, 4, respectively. 4, 5, 6, 7, comprising hinge parts 1 and 4 and hollow rods 2 and 3 and hinge parts 4 and 7 and hollow rods 5 and 6, respectively, pivotally connected by bolts. The hinge part 1 supports the heat shield 9 and the hinge part 7 has a shaft pin 9 for pivotally mounting the support arm to a table or wall holder, which is not shown in the drawing.

Onton tangon 3 sisään on kuvion 3 esittämällä tavalla kiinnitetty kierrevetojousen 10 toinen pää (esittämättä), sen toisen pään ollessa kiinnitetty yhdysosan 12 toiseen päähän, jonka yhdysosan muodostaa teräslankapätkä koukkumaisine päineen. Yhdysosan 12 toinen pää on kiinnitetty tangon 2 pään sisään. On selvää, että tämän yhdysosan toteutus ja kiinnitys voi vaihdella paljon, edellyttäen että se kestää vetorasituksen ja siirtää vetovoiman oikeaan vaikutuspistee-seen nivelosassa 4. Kitkan pienentämiseksi jousen 10 ja yhdysosan 12 välisessä liitoskohdassa on onton tangon 3 sisään sovitettu esim. nailonia oleva helposti liukuva kappale 11.Attached to the hollow rod 3 is one end (not shown) of a helical tension spring 10 as shown in Fig. 3, the other end being attached to the other end of a connecting portion 12 formed by a piece of steel wire with hook-like ends. The other end of the connecting part 12 is fixed inside the end of the rod 2. It is clear that the design and fastening of this connecting part can vary a lot, provided that it withstands the tensile stress and transfers the traction to the correct point of action in the hinge part 4. To reduce friction at the joint between the spring 10 and the connecting part 12, a nylon, e.g. 11.

Kuvio 2 esittää alemman nivelen osaa, jossa onton tangon 5 sisään on kiinnitetty kierrevetojousen 13 toinen pää (esittämättä), jonka jousen toinen pää on tangon sisällä kiinnitetty esim. nailonia olevaan helposti liukuvaan kappaleeseen 15, joka on varustettu tangossa 5 olevan pitkittäisen raon 17 läpi ulkonevalla haalla 16. YhdysosaFig. 2 shows a part of a lower joint in which the other end of a helical tension spring 13 (not shown) is fixed inside the hollow rod 5, the other end of which spring is fixed inside the rod to e.g. haalla 16.
