Description

151318151318

Opfindelsen angår en afbalanceret bærearm for eksempelvis en lampe eller en lup t og som omfatter to med hinanden ledforbundne armparal-lellogrammer, som hvert består af mindst to hule stænger, der ved begge ender er svingeligt forblindet med en leddel, og hvor en stang i hvert armparallellogram er fjederbelastet i forhold til en leddel ved hjælp af mindst en trykfjeder, som med den ene ende ligger an mod et fast anlæg indvendigt i den hule stang og er fuldstændigt optaget i denne, og hvis anden ende ligger an mod et i stangen giideligt organ, der samvirker med leddelene.BACKGROUND OF THE INVENTION The invention relates to a balanced support arm for, for example, a lamp or a loupe t, comprising two interconnected arm-parallelograms, each consisting of at least two hollow bars, pivotally blinded at one end, and a rod at each end. arm parallelogram is spring loaded with respect to a joint member by means of at least one compression spring which abuts one end against a fixed abutment inside the hollow rod and is completely accommodated therein and the other end abuts against a rod which is removable in the rod. that interacts with the joints.

Fra det engelske patentskrift nr. 813.721 kendes en bærearm med kun ét armparallellogram med en i en af dettes hule stænger an- 2 151318 bragt trykfjeder, hvis anden ende ligger an mod et giideligt organ, som udenfor stangen er udstyret med en rulle, der ruller på en krum kamflade på leddelen. Med en sådan bærearm opnås afbalancering indenfor et begrænset svingningsområde, men de udvendigt anbragte, kraftoverførende dele er stærkt udsat for beskadigelse og forurening.British Patent No. 813,721 discloses a support arm having only one arm parallelogram with a compression spring arranged in one of its hollow rods, the other end of which abuts against a positive member, which is equipped with a roller rolling outside the rod. on a curved cam surface on the joint. With such a support arm, balancing is achieved within a limited oscillation range, but the externally positioned, power-transmitting parts are highly susceptible to damage and contamination.

Opfindelsen har til fonnål at anvise en bærearm af den omhandlede art, der er således udformet, at man undgår denne mangel, og dette er ifølge opfindelsen opnået ved, at det glidelige organ, der f.eks. består af nylon, ligger an mod den ene ende af et stift forbindelsesorgan, hvis anden ende er svingeligt lejret i leddelen.The invention has for its object to provide a support arm of the kind in question, which is designed to avoid this defect, and this is achieved according to the invention by the sliding means which e.g. consisting of nylon, abuts one end of a rigid connecting member, the other end of which is pivotally mounted in the hinge member.

Det stive forbindelsesorgan kan i den ende, der er lejret i leddelen, være udformet som en togrenet gaffel eller et øje, som er lejret på en lejetap i leddelen, og gaffelen eller øjet kan alternativt have en aflang åbning på tværs af forbindelsesdelens længderetning, medens lejetappen kan have et modsvarende tværsnit, således at ved bærearmens svingning flyttes det fjedrende organs angrebspunkt på leddelen fra den ene side af gaffelen eller øjet til den anden.The rigid connecting member may, at the end which is mounted in the linkage member, be formed as a bifurcated fork or eye, which is mounted on a bearing pin in the linkage member, and the fork or eye may alternatively have an oblong opening across the longitudinal direction of the linkage member, the bearing pin may have a corresponding cross-section such that, when the support arm pivots, the point of attack of the resilient member on the articulation member is moved from one side of the fork or eye to the other.

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 ifølge opfindelsen, fig. 2 viser set fra siden og delvis i snit det midterste led af bærearmen ifølge fig. 1 i større målestok, og fig, 3 viser set fra siden og i større målestok en anden udførelsesform for forbindelsesorganet og dettes lejring i leddelen.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 according to the invention; FIG. 2 is a side view, partly in section, of the middle link of the support arm of FIG. Fig. 1 is a larger scale view, and Fig. 3 is a side view, on a larger scale, of another embodiment of the connector and its bearing in the linkage.

Den viste bærearm består af to med hinanden ledforbundne armparal-léllogrammer 1, 2, 3> 4, henholdsvis 4, 5, 6, 7 bestående af leddelene 1 og 4 og hule stænger 2 og 4, henholdsvis af leddelene 4 og 7 og hule stænger 5 og 6, og som er svingeligt forbundne med 3 151318 bolte. Leddet 1 bærer en lampeskærm 9, og leddet 7 har en akseltap 8 til svingelig lejring af bærearmen i en bord- eller vægholder, som ikke er vist på tegningen.The supporting arm shown consists of two interconnected arm parallel logograms 1, 2, 3> 4, 4, 5, 6, 7, respectively, consisting of the link parts 1 and 4 and hollow bars 2 and 4, respectively of the link parts 4 and 7 and hollow bars. 5 and 6 and are pivotally connected to 3 151318 bolts. The link 1 carries a lamp shade 9, and the link 7 has a shaft pin 8 for pivotally mounting the support arm in a table or wall holder not shown in the drawing.

Indvendigt i den hule stang 3 er som vist i fig. 2 anbragt en skrueformet trækfjeder 10, hvis ene ende ikke er vist, og hvis anden ende er haget sammen med den ene ende af et forbindelsesorgan 12 i form af et stykke ståltråd med krogformede ender. Forbindelsesorganets anden ende er fasthaget i stangens 2 ende. Udformningen og fastgørelsen af forbindelsesorganet 12 kan ske på mange måder, når blot organet tåler trækpåvirkning og vil overføre trækkraften til det rigtige angrebspunkt på leddelen 4. For at mindske friktionen i forbindelsen mellem fjederen 10 og forbindelsesorganet 12 er der anbragt et let giideligt organ 11, f.eks. af nylon, indvendigt i den hule stang 3.Inside the hollow rod 3 is shown in FIG. 2, a helical tension spring 10 is provided, one end of which is not shown and the other end of which is hooked together with one end of a connecting member 12 in the form of a piece of steel wire with hook-shaped ends. The other end of the connecting member is secured to the end of the rod 2. The design and attachment of the connector 12 can be accomplished in many ways as long as the member can withstand drag and will transfer the traction to the correct point of attack on the link member 4. In order to reduce the friction in the connection between the spring 10 and the connector 12, an easily slidable member 11 is provided. eg. of nylon, inside the hollow rod 3.

Afbalanceringen af det andet armparallellogram 4, 5» 6, 7 sker ved hjælp af en skrueformet trykfjeder 13» hvis ene ende ligger an mod et ikke vist anlæg, og hvis anden ende bærer et letglide-ligt organ 15, f.eks. af nylon, på en tap 16 og med en hul lejeflade 17 for den ene ende af forbindelsesorganet 14, hvis anden ende danner en to-grenet gaffel 19, der er lejret på en lejetap 18 i leddelen 4.The balancing of the second arm parallelogram 4, 5 »6, 7 is effected by means of a helical compression spring 13» one end of which abuts against a plant not shown, and the other end of which has a slidable member 15, e.g. of nylon, on a pin 16 and having a hollow bearing surface 17 for one end of the connecting member 14, the other end of which forms a two-branched fork 19 mounted on a bearing pin 18 in the link member 4.

Med henblik på at øge afbalanceringen kan som vist i fig. 3 forbindelsesorganets 14 gaffelformede ende 19 være bred og have anlæg mod to ved siden af hinanden anbragte lejetappe 18 eller mod en enkelt bred lejetap som vist med brudt linie i fig. 3. På denne måde flyttes fjederens angrebspunkt fra den ene gren af gaffelen til den anden.In order to increase the balance, as shown in FIG. 3, the forked end 19 of the connector 14 is wide and abuts against two adjacent bearing pins 18 or against a single wide bearing pin as shown in broken line in FIG. 3. In this way, the point of attack of the spring is moved from one branch of the fork to the other.
