Description

  

  Trépied     pliant       La présente invention a pour objet un tré  pied pliant, caractérisé en ce qu'il comprend un       tube-support    vertical sur la périphérie duquel  sont fixées trois paires équidistantes de flasques  verticaux, chacune des paires de     flasques    for  mant les branches d'une chape à laquelle est  articulée, au moyen d'un pivot, l'extrémité su  périeure de l'une des jambes du trépied, et une  bague coulissant sur le tube-support et présen  tant du côté inférieur trois becs dont chacun  pénètre entre les branches respectives de l'une  des chapes pour servir de butée à l'extrémité  supérieure de la jambe correspondante,

   le tout  étant agencé de façon qu'après avoir     soulevé    la  bague pour dégager les becs hors des chapes,  puis fait pivoter les jambes autour de leur axe  d'articulation respectif pour les ramener paral  lèlement au tube-support et après avoir replacé  la bague dans sa position initiale, le trépied re  plié est prêt à être transporté.    Le dessin annexé représente, à titre d'exem  ple, une forme d'exécution du trépied pliant,  objet de l'invention.  



  Les     fig.    1 à 3 sont des vues du trépied en  position dépliée, dont la     fig.    1 est une coupe  verticale d'une partie du tube avec la bague  coulissante et un pied déployé ; la     fig.    2, une  coupe en plan, suivant la ligne brisée     II-II    de  la     fig.    1, et la     fig.    3, une coupe transversale,  suivant la ligne<I>1l1-111</I> de la     fig.    1.    La     fig.    4 est une vue d'un détail du     tube-          support.       La     fig.    5 est une vue en plan de la     fig.    4.

    La     fig.    6 est une vue de détail de la bague  coulissante.    La     fig.    7 est une vue en     plan    de la     fig.    6.    La     fig.    8 est une vue partielle en élévation  du trépied en position repliée.  



  Dans la forme d'exécution représentée, le  trépied pliant comprend un tube-support 1 à  la périphérie duquel sont fixées, par exemple  par soudure, trois paires équidistantes de flas  ques, telles que les flasques 2, 2', formant les  branches d'une chape 3     (fig.    4 et 5). Les trois  chapes 3, 4 et 5 sont, chacune, pourvues d'un  pivot 6     (fig.    1 à 3), constitué par un boulon, sur  lequel est articulée une jambe 7 du trépied.  



  Sur la périphérie du tube-support 1 est  montée une bague 8 coulissant le long dudit  tube. La bague 8 présente du côté inférieur trois  becs 9, 9' et 9"     (fig.    6 et 7), destinés à péné  trer dans les chapes 3, 4 et 5 respectivement,  et reliés entre eux à leur partie supérieure, par  exemple par soudure, par des entretoises 10,  10' et 10" respectivement, en forme d'arcs de  cercle. Lorsque le trépied est déplié, les becs  9, 9' et 9" servent de butée aux jambes 7 dont  les extrémités supérieures sont taillées en bi  seau, comme représenté à la     fig.    1.      Pour replier le trépied en vue de son trans  port, la bague 8 est soulevée en la faisant glis  ser le long du tube 1 jusqu'à ce que les becs  soient dégagés des chapes.

   Puis on fait pivoter  les jambes 7 dans la direction indiquée par la       flèche        f    de la     fig.    1, jusqu'à ce qu'elles occupent  une position parallèle au tube, comme repré  senté à la     fig.    8, la bague étant rabaissée dans  sa position initiale.  



       Le    trépied pliant est destiné à recevoir de  multiples applications. Sur le tube-support peut  être monté, par exemple, un dispositif de signa  lisation, tel qu'une lampe, un disque ou une  table pliante. Il peut servir également de     sup-          port-de    mire, de lunette, d'appareil de géodé  sie ou autres instruments portatifs semblables.



  Folding tripod The present invention relates to a folding tripod, characterized in that it comprises a vertical support tube on the periphery of which are fixed three equidistant pairs of vertical flanges, each of the pairs of flanges forming the branches of a clevis to which is articulated, by means of a pivot, the upper end of one of the tripod's legs, and a ring sliding on the support tube and presenting on the lower side three jaws, each of which penetrates between the branches respective of one of the yokes to serve as a stop at the upper end of the corresponding leg,

   the whole being arranged so that after lifting the ring to release the nozzles from the yokes, then pivoting the legs around their respective articulation axis to bring them parallel to the support tube and after replacing the ring in its original position, the folded tripod is ready to be transported. The accompanying drawing shows, by way of example, an embodiment of the folding tripod, object of the invention.



  Figs. 1 to 3 are views of the tripod in the unfolded position, of which fig. 1 is a vertical section of part of the tube with the sliding ring and a deployed foot; fig. 2, a plan section, along the broken line II-II of FIG. 1, and fig. 3, a cross section, taken along the line <I> 1111-111 </I> of FIG. 1. FIG. 4 is a view of a detail of the support tube. Fig. 5 is a plan view of FIG. 4.

    Fig. 6 is a detail view of the sliding ring. Fig. 7 is a plan view of FIG. 6. FIG. 8 is a partial elevational view of the tripod in the folded position.



  In the embodiment shown, the folding tripod comprises a support tube 1 at the periphery of which are fixed, for example by welding, three equidistant pairs of flanges, such as the flanges 2, 2 ', forming the branches of' a yoke 3 (fig. 4 and 5). The three yokes 3, 4 and 5 are each provided with a pivot 6 (Fig. 1 to 3), consisting of a bolt, on which is articulated a leg 7 of the tripod.



  On the periphery of the support tube 1 is mounted a ring 8 sliding along said tube. The ring 8 has on the lower side three nozzles 9, 9 'and 9 "(fig. 6 and 7), intended to penetrate into the yokes 3, 4 and 5 respectively, and interconnected at their upper part, for example by welding, by spacers 10, 10 'and 10 "respectively, in the form of circular arcs. When the tripod is unfolded, the jaws 9, 9 'and 9 "serve as a stopper for the legs 7, the upper ends of which are cut into a twin bucket, as shown in Fig. 1. To fold the tripod for transport, the ring 8 is lifted by sliding it ser along the tube 1 until the nozzles are free from the yokes.

   Then the legs 7 are rotated in the direction indicated by the arrow f in FIG. 1, until they occupy a position parallel to the tube, as shown in fig. 8, the ring being lowered to its initial position.



       The folding tripod is intended for multiple applications. On the support tube can be mounted, for example, a signaling device, such as a lamp, a disc or a folding table. It can also be used as a staff, telescope, geodetic device or other similar portable instruments.
