  ROTULE   FIXE;     FORMANT   SUPPORT DE CHAPE, OSCILLANTE ET TOURNANTE, A BRAS DE LEVIERS INEGAUX A EQUILIBRAGE ET FREINAGE   REGLABLES.   



   La présente invention se rapporte à un support à rotule fixe., sur lequel peut osciller de bas en haut et de haut en bas, de gauche à droite et de droite   à   gauches une chapeen une ou deux parties à pression réglable pour le freinage des oscillations et des rotations? et à équilibrage réglable par un contrepoids, en une ou deux pièces, qu'on peut déplacer pour faire varier le bras de levier,pour équilibrer approximativement la charge suppor- tée par le petit bras de leviero 
Les objets supportés par le petit bras de levier varie en fonc- tion du but   recherchéo   
A titre   d'exemple,   le dessin annexé à la présente demande, montre une application particulièrement intéressante de l'invention à une lampe de bureau. 



   La figure 1 montre schématiquement le réglage-du contre-poids; 
La figure 2 montre l'ensemble appliqué à une lampe de bureau; 
La figure 3 est une variante d'application à une lampe de bureau à tubes télescopiques; 
Les figures 4 à 6 représentent différentes positions que peut prendre la lampe de la figure 2; 
En se reportant au dessin,, la bouler ou rotule 1 est enchassée dans une chape 2, ce qui permet à la lampe d'osciller et de tourner (le socle et le fût portant la boule rotule restant fixes). 



   La chape 2 porte,,par son petit bras, la charge à équilibrer (lampe dans l'exemple choisi) par un contrepoids 3,à position réglable porté par son grand bras 
4 est un bouton de réglage faisant pression sur la chape 2 qui enchâsse la rotule 1; cette pression peut être très légère du fait de l'é-

   quilibrage   de l'ensemble dans tous les sens, ce qui permet même de l'accro- cher   au mur..   comme le montre les figures 4 à 6. 



   Une deuxième chape 5 solidaire de l'abat-jour 6 montée sur rotule fixe 7 a sa pression réglable par le bouton 8 et permet de compléter l'ensemble pour lui permettre toutes les variations d'orientation en vue d'un bon éclairage, le bras   intermédiaire   étant constitué par un flexible 9, ou un tube simple et télescopique 10 (figure 3).

   Un étau de serrage supportant le fût, peut remplacer le socle, pour la fixation de l'ensemble sur une tableun bureau, etc; un projecteur, un écouteur téléphonique, etc. peuvent aussi être aisément supportéso 
La douceur de fonctionnement   dûe   à l'équilibrage de l'ensemble ne nécessitant qu'une légère pression, constitue un grand avantage sur les bras de lampe supportés par une rotule mobile, non équilibrée qui doit être fortement serrée dans son logement proportionnellement au porte-à-faux deman- dé, et qui se dérègle   constammento   
Bien entendu, les modes de réalisation ci-dessus décrits   sont .     indicatifs..  et peuvent avoif d'autres formes,

  FIXED BALL; FORMING A SCREED SUPPORT, OSCILLATING AND ROTATING, WITH ARMS OF UNEVEN LEVERS WITH ADJUSTABLE BALANCING AND BRAKING.



   The present invention relates to a fixed ball joint support., On which can oscillate from bottom to top and top to bottom, from left to right and from right to left a one or two-part adjustable pressure cap for braking oscillations and rotations? and with adjustable balancing by a counterweight, in one or two pieces, which can be moved to vary the lever arm, to approximately balance the load supported by the small lever arm.
The objects supported by the small lever arm vary according to the desired goal.
By way of example, the drawing appended to the present application shows a particularly interesting application of the invention to a desk lamp.



   Figure 1 shows schematically the adjustment of the counterweight;
Figure 2 shows the assembly applied to a desk lamp;
FIG. 3 is an alternative application to a desk lamp with telescopic tubes;
Figures 4 to 6 show different positions that the lamp of Figure 2 can take;
Referring to the drawing, the ball or ball joint 1 is embedded in a yoke 2, which allows the lamp to oscillate and rotate (the base and the barrel carrying the ball joint remaining fixed).



   The clevis 2 carries, by its small arm, the load to be balanced (lamp in the example chosen) by a counterweight 3, with adjustable position carried by its large arm
4 is an adjustment button pressing on the yoke 2 which engages the ball 1; this pressure can be very light due to the

 <Desc / Clms Page number 2>

   balancing of the whole in all directions, which even makes it possible to hang it on the wall .. as shown in figures 4 to 6.



   A second cap 5 integral with the lampshade 6 mounted on a fixed ball joint 7 with its adjustable pressure by the button 8 and allows to complete the set to allow all the variations of orientation for a good lighting, the intermediate arm consisting of a flexible 9, or a simple telescopic tube 10 (Figure 3).

   A clamping vise supporting the barrel, can replace the base, for fixing the assembly on a table, desk, etc; a projector, a telephone headset, etc. can also be easily supported
The smooth operation due to the balancing of the assembly requiring only a slight pressure, constitutes a great advantage on the lamp arms supported by a movable, unbalanced ball joint which must be strongly tightened in its housing in proportion to the holder. wrongly requested, and which is constantly out of order.
Of course, the embodiments described above are. indicative .. and may have other forms,

   but those indicated allow a low cost price and constitute one of the elements of their application of the invention, these elements being able to be used together or separately
CLAIMS.



   Fixed ball joint forming an oscillating and rotating clevis support, with unequal lever arms, with adjustable balancing and braking, characterized in that
1 - The ball joint is embedded between the two branches of a yoke each provided, for this purpose, with a circular hole.



   2 - An adjustable device makes it possible to modify the pressure of the two branches of the yoke against the ball joints
3 - The two branches of the yoke form unequal lever arms: the smaller one supporting the load and the larger one a counterweight with an adjustable position according to the load.



   4 - This device is particularly intended for desk lamps.
