Description

  

  Raccord pour l'assemblage d'éléments de radiateurs.    L'objet de la présente invention est un  raccord pour l'assemblage d'éléments de ra  diateur, caractérisé en ce qu'il est formé d'un  corps tubulaire présentant au moins deux  arrêts intérieurs permettant de le saisir au  moyen d'une clé de serrage -et portant exté  rieurement à chaque extrémité un filet, les  deux filets étant de pas différents et desti  nés à être vissés chacun dans l'un de deux  éléments consécutifs de radiateur.  



  Le dessin ci-joint montre, à titre d'exem  ple, une forme d'exécution de l'objet de l'in  vention.  



  La fi-. 1 est une coupe suivant l'axe du  raccord et la tête de deux éléments de radia  teur;  La     fig.    2 est une vue d'une variante de  la forme     d'exécution    du raccord;  La     fig.    3 est une coupe suivant la ligne       I-I    de la     fig.    2.  



  Dans le dessin, on     distingue    le raccord 1,  les anneaux intérieurs 2 des éléments de ra  diateur, les éléments de radiateur 3 et l'an  neau de distance 4 inséré entre les éléments    de radiateur. Le raccord 1     présente    intérieu  rement deux saillies 5 diamétralement oppo  sées l'une à l'autre formant les arrêts et  servant à saisir le raccord intérieurement au  moyen d'une clé. On peut ainsi le visser  dans les anneaux intérieurs des deux élé  ments consécutifs 3 du radiateur. Les deux  filets extérieurs 6 et 7 sur le raccord 1 sont  de pas différents pour obtenir pendant le ser  rage de ce dernier un effet différentiel qui  facilite avec peu d'effort un serrage très ef  ficace entre les éléments de radiateur.  



  La partie non     filetée    du raccord peut  aussi recevoir la forme d'un hexagone ou  octogone qui se reproduisent intérieurement  formant ainsi les arrêts pour poser la clé de  serrage.  



  Les     diamètres    extérieurs des deux filets  à pas différents peuvent être de la même  dimension au l'un peut être plus petit que  l'autre pour faciliter l'introduction du rac  cord dans les anneaux intérieurs des éléments  de     radiateur.  



  Connection for the assembly of radiator elements. The object of the present invention is a connector for the assembly of radiator elements, characterized in that it is formed of a tubular body having at least two interior stops allowing it to be gripped by means of a key. clamping -and carrying externally at each end a thread, the two threads being of different pitches and intended to be each screwed into one of two consecutive radiator elements.



  The accompanying drawing shows, by way of example, one embodiment of the object of the invention.



  The fi-. 1 is a section along the axis of the fitting and the head of two radiator elements; Fig. 2 is a view of a variant of the embodiment of the connector; Fig. 3 is a section taken along line I-I of FIG. 2.



  In the drawing, a distinction is made between the connector 1, the inner rings 2 of the radiator elements, the radiator elements 3 and the distance ring 4 inserted between the radiator elements. The connector 1 internally has two protrusions 5 diametrically opposed to one another forming the stops and serving to grip the connector internally by means of a key. It can thus be screwed into the inner rings of the two consecutive elements 3 of the radiator. The two external threads 6 and 7 on the connection 1 are of different pitches in order to obtain, during the tightening of the latter, a differential effect which facilitates, with little effort, very effective clamping between the radiator elements.



  The non-threaded part of the fitting can also take the shape of a hexagon or octagon which reproduce internally, thus forming the stops for fitting the tightening key.



  The outer diameters of the two threads at different pitches may be of the same dimension or one may be smaller than the other to facilitate the introduction of the connector into the inner rings of the radiator elements.

Claims

CLAIM Assembly connector for radiator elements, characterized in that it is formed by a tubular body having at least two internal stops allowing it to be gripped by means of a tightening key and carrying a thread on the outside at each end , the two threads being of different pitches and each being screwed into one of two consecutive radiator elements.
