Abstract
Description
Dispositif de fixation réglable d'un dispositif d'éclai
rage sur un support, notamment pour tables à dessin."
La présente invention concerne un dispositif de fixation réglable d'un dispositif d'éclairage allongé sur un support plan, le dispositif d'éclairage ayant des deux côtés respectivement un bras recourbé vers l'arrière et qui est fixé à la face arrière du support sur un chariot, et les deux chariots étant maintenus de force à la même hauteur chaque fois dans un organe de guindage de chariot, en étant coulissants le long du support.Adjustable fixing device for a lighting device
rage on a support, especially for drawing tables. "
The present invention relates to an adjustable fixing device for a lighting device lying on a flat support, the lighting device having on both sides respectively an arm bent backwards and which is fixed to the rear face of the support on a carriage, and the two carriages being forcibly held at the same height each time in a carriage luffing member, by sliding along the support.
On connaît un tel dispositif selon le brevet allemand 31 04 579. Sur ce dispositif d'éclairage connu, on considère parfois comme inconvénient que les bras fixés dans des chariots sur la face arrière du support et qui portent le dispositif d'éclairage en particulier si ces bras sont relativement longs, sont quelque peu élastiques, de sorte que le dispositif d'éclairage n'est pas immédiatement immobile après son réglage. Such a device is known according to German patent 31 04 579. On this known lighting device, it is sometimes considered a drawback that the arms fixed in carriages on the rear face of the support and which carry the lighting device in particular if these arms are relatively long, are somewhat elastic, so that the lighting device is not immediately stationary after its adjustment.
La présente invention a pour but d'éviter cet inconvénient. The present invention aims to avoid this drawback.
A cet effet, l'invention concerne un dispositif de fixation du type ci-dessus caractérisé en ce que les deux bras comportent chacun une articulation. Grâce aux articulations, on peut diminuer sensiblement de moitié la longueur des bras ou dans tous les cas réduire fortement cette longueur, ce qui exclut tout mouvement élastique. Par ailleurs en plus du coulissement des chariots le long de la face arrière du support, il est possible de basculer le dispositif d'éclairage suivant un arc relativement petit en avant de la surface supérieure du support qui est par exemple une planche à dessin . Cela donne une adaptation très rapide, avantageuse du dispositif d'éclairage aux différentes conditions.En particulier, les articulations permettent une position pliée des deux bras pour contourner latéralement des accessoires de dessin en saillie par rapport à la table à dessin comme par exemple les règles d'une machine à dessiner, les rails de traçage ou analogues sans qu > il ne soit nécessaire de coulisser les chariots. To this end, the invention relates to a fixing device of the above type characterized in that the two arms each have a hinge. Thanks to the articulations, the length of the arms can be substantially reduced by half or in any case greatly reduce this length, which excludes any elastic movement. Furthermore, in addition to the sliding of the carriages along the rear face of the support, it is possible to tilt the lighting device in a relatively small arc in front of the upper surface of the support which is for example a drawing board. This gives a very rapid, advantageous adaptation of the lighting device to the different conditions. In particular, the articulations allow a folded position of the two arms to bypass laterally drawing accessories projecting from the drawing table such as the rulers of a drawing machine, the tracing rails or the like without it being necessary to slide the carriages.
Les articulations sont prévues avantageusement à une certaine distance devant le plan du support pour permettre un réglage optimum du dispositif d'éclairage en fonction de chaque application. Cette position des articulations peut se réaliser par une fixation appropriée des segments de bras du côté arrière sur les chariots. The joints are advantageously provided at a certain distance in front of the plane of the support to allow optimum adjustment of the lighting device according to each application. This position of the articulations can be achieved by an appropriate fixing of the arm segments on the rear side on the carriages.
Un exemple de réalisation de 1 'inven- tion sera décrit de manière plus détaillée à l'aide des dessins dans lesquels :
- la figure 1 est une vue de côté schématique du dispositif de fixation avec le dispositif d'éclairage et la table à dessin.An exemplary embodiment of the invention will be described in more detail with the aid of the drawings in which:
- Figure 1 is a schematic side view of the fixing device with the lighting device and the drawing table.
- la figure 2 est une vue inclinée partielle du dispositif représenté à la figure 1. - Figure 2 is a partial inclined view of the device shown in Figure 1.
Deux organes de guidage de chariot 12 parallèles, disposés le long de la table à dessin sont fixés à la face arrière de la table à dessin 10 ; ces organes de guidage reçoivent respectivement un chariot 14 de manière coulissante. Comme cela n'est pas explicité de manière plus détaillée mais comme cela découle du brevet allemand 31 04 579, de manière connue, le mouvement des deux chariots 14 est couplé de façon forcée par un axe commun 16 pour que les deux chariots 14 soient toujours maintenus à la même hauteur. Two parallel carriage guide members 12 arranged along the drawing table are fixed to the rear face of the drawing table 10; these guide members respectively receive a carriage 14 in a sliding manner. As this is not explained in more detail but as follows from German patent 31 04 579, in known manner, the movement of the two carriages 14 is forcibly coupled by a common axis 16 so that the two carriages 14 are always kept at the same height.
Chacun des chariots 14 dont un seul est représenté aux figures, reçoit le segment 18 à quatre pans, recourbé vers l'intérieur du segment de bras arrière 20, respectif pour le fixer dans une position prédéterminée. Each of the carriages 14, only one of which is shown in the figures, receives the four-sided segment 18, bent inwardly of the rear arm segment 20, respective to fix it in a predetermined position.
L'articulation 22 relie un segment de bras avant 24 de manière pivotante à un segment de bras arrière 20. Les deux segments de bras avant 24 portent à leur extrémité extérieure le dispositif d'éclairage allongé 26.The articulation 22 connects a front arm segment 24 pivotally to a rear arm segment 20. The two front arm segments 24 carry the elongated lighting device 26 at their outer end.
L'axe d'articulation 28 des deux articulations 22 est situé à une faible distance en avant de la surface supérieure 20 de la table à dessin 10. On peut durcir plus ou moins le mouvement de chaque articulation 22 par un serrage plus ou moins fort d'une vis 32 traversant chaque articulation pour arriver à un réglage quelconque. The articulation axis 28 of the two articulations 22 is located a short distance in front of the upper surface 20 of the drawing table 10. The movement of each articulation 22 can be more or less hardened by a more or less tightening a screw 32 passing through each articulation to arrive at any adjustment.
