par un profile en metal, definit dans sa partie interieure une rainure longitudinale (S) dans laquelle il est possible de loger la tete (6) d'un boulon a tete en T. designe globalement par le chiffre (7) et dote d'une tige filetee (8) connue en elle-meme. Comme indique dans l'exemple de realisation susmentionne, la rainure (S) presente une surface de fond (2), une padre de surfaces paralleles laterales (3) qui s'etendent a partir des bords lateraux opposes de la surface de fond (2) perpendiculairement a cette derriere, et une padre de surfaces coplanaires anterieures (4) qui s'etendent a partir des bords anterieurs des surfaces laterales (3) parallelement a la surface de fond (2), de maniere a definir une fente longitudinale (5) qui s'etend sur toute la longueur du montant 1. Dans le mode de realisation illustre, la rainure (S) est definie par la cavite interne d'un profile en C, presentant une paroi de fond (F), une padre de parois laterales (L) et une padre de parois anterieures (A) separees entre elles par une fente longitudinale (5) a cotes paralleles. Generalement, dans les profiles de ce type, les deux parois anterieures (A) vent repliees a leur extremite interne, de maniere a definir une padre de bords lateraux internee (B) qui s'etendent perpendiculairement vers la by a metal profile, defines in its inner part a longitudinal groove (S) in which it is possible to accommodate the head (6) of a T-head bolt generally designated by the number (7) and provided with a threaded rod (8) known in itself. As indicated in the above-mentioned embodiment, the groove (S) has a bottom surface (2), a pad of parallel lateral surfaces (3) which extend from the opposite lateral edges of the bottom surface (2 ) perpendicular to this rear, and a pad of anterior coplanar surfaces (4) which extend from the anterior edges of the lateral surfaces (3) parallel to the bottom surface (2), so as to define a longitudinal slot (5 ) which extends over the entire length of the upright 1. In the illustrated embodiment, the groove (S) is defined by the internal cavity of a profile in C, having a bottom wall (F), a pad of lateral walls (L) and a pad of anterior walls (A) separated from each other by a longitudinal slot (5) with parallel dimensions. Generally, in profiles of this type, the two anterior walls (A) are folded at their internal ends, so as to define a pad of internal lateral edges (B) which extend perpendicularly towards the
paroi de fond (F).back wall (F).
La tete (6) du boulon (7) a une forme substantiellement parallelepipedique avec des dimensions telles qu'elles permettent de conserver un The head (6) of the bolt (7) has a substantially parallelepiped shape with dimensions such that they allow a
certain jeu a l'interieur de la rainure (S) (figure 2). some play inside the groove (S) (figure 2).
Comme indique, la tete (6) est inseree par la fente longitudinale (5), en etant substantiellement alignee As indicated, the head (6) is inserted through the longitudinal slot (5), being substantially aligned
SR 23041 IT/JCISR 23041 IT / JCI
sur cette derriere, puis lorequ'elle est dans la rainure (S), on la fait pivoter a 90 de maniere a la positionner transversalement par rapport a la fente (5) et a ce qu'elle reste ainsi bloquee d'un cote contre la surface de fond (2) et du cote oppose contre la padre de surfaces anterieures (4) ou contre les extremites libres des deux bords lateraux internee (B). Pour eviter d'eventuels blocages de la tete (6) contre les surfaces laterales (3) de la rainure (S) pendant la rotation a l'interieur de ladite rainure, les deux faces verticales laterales (par rapport a un observateur de la figure 1) de la tete du boulon, reperees par le chiffre (9) sur les figures, vent inclinees selon un angle different de 90 , par exemple, 87 (figure 3) par rapport aux deux faces horizontales superieure et inferieure de la tete qui on this back, then lorequ'elle in the groove (S), it is rotated 90 so as to position it transversely to the slot (5) and so that it remains so blocked on one side against the bottom surface (2) and on the opposite side against the pad of anterior surfaces (4) or against the free ends of the two internal lateral edges (B). To avoid possible blockages of the head (6) against the lateral surfaces (3) of the groove (S) during the rotation inside said groove, the two vertical side faces (with respect to an observer of the figure 1) from the head of the bolt, identified by the number (9) in the figures, wind inclined at an angle different from 90, for example, 87 (Figure 3) relative to the two upper and lower horizontal faces of the head which
sont, quant a elles, reperees par le chiffre 10. are identified by the number 10.
Pour eviter que le boulon, lorsque la tete est inseree dans la rainure comme indique precedemment, puisse glisser librement le long de ladite rainure, et que l'operateur soit, par consequent, oblige de l'immobiliser manuellement a la position souhaitee, la tete (6) du boulon, selon l' invention, est dotee d'un element elastique (11) fixe sur la face (12) opposee a la tige (8), c'est-a-dire faisant face a la surface de fond (2) de la rainure. De preference, ['element elastique (11) est un ressort a lames, avec une partie centrale (13) fixce sur la face (12) de la tete (6) du boulon au moyen d'un organe d' assemblage (15) de type connu, et une padre de segments lateraux incurves (14), To avoid that the bolt, when the head is inserted into the groove as indicated above, can slide freely along said groove, and that the operator is, therefore, obliged to immobilize it manually in the desired position, the head (6) of the bolt, according to the invention, is provided with an elastic element (11) fixed on the face (12) opposite the rod (8), that is to say facing the bottom surface (2) of the groove. Preferably, the elastic element (11) is a leaf spring, with a central part (13) fixed on the face (12) of the head (6) of the bolt by means of an assembly member (15). of known type, and a pad of curved lateral segments (14),
