    • Dans la fig. 1 un mode de réalisation d'un anneau articulé 10 selon l'invention est représenté avec, comme exemples, deux moitiés d'anneaux différents, un anneau 11 du type oeil et un anneau 12 à barrette. In fig. 1 an embodiment of a hinged ring 10 according to the invention is shown with, as examples, two halves of different rings, a ring 11 of the eye type and a ring 12 with a bar.

    L'anneau articulé 10 comprend un boulon d'ancrage ou tige de fixation 13 destinée à être assemblée par une extrémité à une charge à lever par vissage. Un manchon 14 est enfilé sur le boulon 13 et touche la tête du boulon 13 avec une de ses extrémités. Une douille 15 est enfilée sur le boulon 13 et fixée sur celui-ci par frettage de sorte que dans la position de service un flasque 16 solidaire de la douille 15 à une de ses extrémités se trouve éloigné de la tête du boulon 13. Les dimensions intérieure du manchon et extérieure de la douille, ainsi que leurs longueurs sont telles qu'un jeux existe permettant au manchon 14 de tourner librement sur la douille 15 montée sur le boulon 13.The hinged ring 10 includes a bolt anchoring or fixing rod 13 intended to be assembled by one end to a load to be lifted by screwing. A sleeve 14 is threaded on the bolt 13 and touch the bolt head 13 with one of its ends. A bushing 15 is threaded onto the bolt 13 and fixed on this one by hooping so that in the service position a flange 16 secured to the socket 15 at one of its ends is located far from the bolt head 13. The internal dimensions of the sleeve and outer sleeve, as well as their lengths are such that a game exists allowing the sleeve 14 to rotate freely on the socket 15 mounted on the bolt 13.

    L'anneau articulé 10 comprend en outre un anneau mobile 11 ou 12 par rapport à ladite tige 13 à l'autre extrémité de ladite tige 13.The hinged ring 10 further comprises a mobile ring 11 or 12 with respect to said rod 13 to the other end of said rod 13.

    Deux encoches 17 diamétralement opposées sont prévues dans le manchon 14 à l'extrémité touchant en service le flasque 16 et sont adaptées pour recevoir les extrémités 18 et 19, respectivement d'un anneau 11 ou 12. L'anneau articulé 11 ou 12 est maintenu en place à ses extrémités libres 18, 19 dans les encoches 17 diamétralement opposées du manchon 14 par le flasque 16 de la douille 15, ledit flasque 16 étant coincé entre la charge et le manchon 14 par le boulon 13 serré à fond.Two notches 17 diametrically opposed are provided in the sleeve 14 at the touching end in use the flange 16 and are adapted to receive the ends 18 and 19, respectively of a ring 11 or 12. The hinged ring 11 or 12 is held in place at its free ends 18, 19 in the notches 17 diametrically opposite the sleeve 14 by the flange 16 of the sleeve 15, said flange 16 being wedged between the load and the sleeve 14 by the bolt 13 tightly to the bottom.

    L'anneau à barrette 12 a à l'endroit de la barrette une largeur réduite, de sorte qu'à partir de cet endroit les branches de l'anneau 12 s'évasent en direction du sommet de l'anneau. Ceci a pour effet qu'un crochet d'une élingue utilisée pour lever la charge aux endroits où les branches de l'anneau s'évasent, se déplace en direction du sommet de l'anneau 12 et fait en même temps basculer l'anneau 12 sur le boulon 13 quand l'anneau 12 est monté sur le côté de la charge.The bar ring 12 has at the location of the barrette a reduced width, so that from this place the branches of the ring 12 flare out in direction of the top of the ring. This has the effect that hook of a sling used to lift the load where the branches of the ring flare out, moves towards the top of the ring 12 and makes same time switch the ring 12 on the bolt 13 when the ring 12 is mounted on the side of the load.

    Le boulon 13 peut être à six pans extérieurs 20 et/ou six pans intérieurs 21.The bolt 13 can be external hexagon 20 and / or inner hexes 21.

    Dans la Fig. 3 est montré un perfectionnement de l'assemblage de la douille 15 et du manchon 14 en ce qu'une rainure circulaire 22 est prévue sur la surface intérieure 24 du flasque 16 de la douille 15 et une projection 23 correspondant à la rainure est prévue à l'extrémité du manchon 14 contenant les encoches 17 par cette rainure 22 et projective 23, le manchon 14 et la douille 15 sont maintenus ensembles en direction radiale.In FIG. 3 is shown a improvement of the assembly of the sleeve 15 and the sleeve 14 in that a circular groove 22 is provided on the inner surface 24 of the flange 16 of the socket 15 and a projection 23 corresponding to the groove is provided at the end of the sleeve 14 containing the notches 17 by this groove 22 and projective 23, the sleeve 14 and the sleeve 15 are held together in radial direction.

    Dans la Fig. 4 est montré un perfectionnement de l'assemblage de l'extrémité 18 ou 19 de l'anneau et du manchon 14. Une tête de retenue 25 et prévue à chacune des extrémités libres des anneaux 11 ou 12 et s'engage dans un creux 26 prévu dans la surface intérieure du manchon 14 autour de l'encoche 17 et une rainure circulaire 27 prévue dans la surface intérieure 24 du flasque 16 de la douille 15. Ainsi l'anneau 11 ou 12 ne peut pas seulement basculer autour de ses extrémités libres, mais tourner également avec le manchon 14 autour du boulon 13.In FIG. 4 is shown a perfecting the assembly of the end 18 or 19 of the ring and the sleeve 14. A retaining head 25 and provided at each of the free ends of the rings 11 or 12 and engages in a hollow 26 provided in the surface inside the sleeve 14 around the notch 17 and a circular groove 27 provided in the inner surface 24 of the flange 16 of the sleeve 15. Thus the ring 11 or 12 can not just swing around his free ends but also turn with the sleeve 14 around the bolt 13.

    Dans la Fig. 5 un centrage 28 est prévu sur le côté extérieur 29 du flasque 16 pour faciliter le centrage de l'anneau articulé dans un creux prévu à cet effet sur la charge. In FIG. A centering 28 is provided on the outer side 29 of the flange 16 to facilitate the centering of the articulated ring in a recess provided for this effect on the load.

    Dans la Fig. 2 un maillon de chaíne 31 est agencé à l'anneau 11 (ou 12) ce qui a pour effet que dans le cas d'une fixation latérale à une charge l'axe du boulon se trouve dans un plan contenant le plan du maillon de chaíne 31 et le crochet de l'élingue servant à soulever la charge est parallèle au plan latéral de la charge sur lequel l'anneau articulé est monté.In FIG. 2 a chain link 31 is arranged at ring 11 (or 12) which has the effect that in the case of lateral attachment to a load the axis bolt is in a plane containing the plane of the chain link 31 and the hook of the sling serving to lift the load is parallel to the lateral plane of the load on which the hinged ring is mounted.

    Dans les Fig. 6a, 6b et 6c trois vues différentes d'un autre mode de réalisation d'un anneau articulé selon l'invention sont représentées. Il comprend un boulon d'ancrage 13 sur lequel un anneau 11 du type oeil modifiée est enfilé, ainsi qu'une douille 15 munie à une extrémité d'un flasque 16. L'anneau 11 comprend un secteur 31 aplati pourvu d'un alésage 32 conçu de sorte à pouvoir recevoir dans un creux 33 dans sa surface supérieure 34 autour de l'alésage 32 la tête du boulon 13 et dans un creux 35 dans sa surface inférieure autour de l'alésage 32 le flasque 16 de la douille 15, et dans la partie centrale 37 de l'alésage 32 la douille 15. Les extensions longitudinales de l'anneau 31 du flasque 16, de la partie centrale 37 et du creux 35 sont telles que l'anneau tourne librement sur le boulon 13, quand celui-ci est vissé à fond dans la charge à lever, le jeu entre la charge et la surface inférieure 36 du secteur aplati 31 étant réduit au minimum permettant la libre rotation de l'anneau 11 par rapport à la charge.In Figs. 6a, 6b and 6c three views different from another embodiment of a ring articulated according to the invention are shown. he comprises an anchor bolt 13 on which a ring 11 the modified eye type is threaded, and a socket 15 provided at one end with a flange 16. The ring 11 comprises a flattened sector 31 provided with a bore 32 designed so as to be able to receive in a hollow 33 in its upper surface 34 around the bore 32 the head of the bolt 13 and in a recess 35 in its surface bottom around the bore 32 the flange 16 of the sleeve 15, and in the central portion 37 of the bore 32 the sleeve 15. The longitudinal extensions of the ring 31 of the flange 16, the central portion 37 and of the recess 35 are such that the ring turns freely on bolt 13, when it is fully screwed into the load to lift, the clearance between the load and the surface lower 36 of the flattened sector 31 being reduced to minimum allowing free rotation of the ring 11 by relation to the load.

    Le boulon 13 peut être à tête aplatie avec six pans 38 intérieurs ou à tête normale à six pans 39 extérieurs. Dans le cas de la tête normale, six pans intérieurs 38 peuvent aussi être utilisés seuls ou en combinaison avec six pans extérieurs 39.The bolt 13 can be flattened head with internal hexagon 38 or normal hexagon head 39 exteriors. In the case of the normal head, hexagon interiors 38 may also be used alone or in combination with six outer sides 39.

    La forme de l'anneau 11 en dehors du secteur aplati 31 est particulière en ce sens qu'à partir du sommet de l'anneau le pourtour intérieur s'évase en direction du secteur aplati 31 pour avoir une extension maximum à l'endroit dudit secteur aplati 31. Ceci a pour effet que lors du montage latéral de l'anneau articulé sur une charge à lever, le crochet de l'élingue utilisée pour lever la charge à l'endroit 41 ou 43 de l'anneau 11 se déplace vers l'endroit 40 ou 44, respectivement de l'anneau 11, tout en tirant sur l'anneau 11, qui tourne pour se placer en direction verticale, la position de l'anneau 11 aux figures 6a à c étant une position horizontale.The shape of the ring 11 outside the sector flattened 31 is particular in that from the top of the ring the inner circumference flares out in sector direction flattened 31 to have an extension maximum at the location of the flattened sector 31. This effect only during lateral assembly of the hinged ring on a load to lift, the hook of the sling used to lift the load at point 41 or 43 of ring 11 moves to place 40 or 44 respectively of the ring 11, while pulling on the ring 11, which turns to move in a vertical direction, the position of the ring 11 in FIGS. 6a to c being a position horizontal.

    Au sommet 42 au milieu de l'anneau une pointe de diamant 43 peut être prévue pour faciliter en service le glissement vers l'un ou l'autre côté de la pointe 43 d'un crochet d'une élingue pour soulever la charge.At the top 42 in the middle of the ring a diamond tip 43 may be provided to facilitate in service the sliding to either side of the tip 43 of a hook of a sling to lift the charge.

    Un centrage 29 peut être prévu sur le côté inférieur 30 du flasque 16 pour faciliter le centrage de l'anneau 11 lors du montage, ce centrage étant reçu dans un creux correspondant dans la charge à lever à l'endroit de montage de l'anneau 11.A centering 29 may be provided on the side bottom flange 16 to facilitate the centering of the ring 11 during assembly, this centering being received in a corresponding hollow in the load to be lifted at the mounting location of the ring 11.
