Le dessin annexe reprMente, ä titre d'exemple, une forme d'execution de 1'appa- reil objet de 1'invention. The appended drawing shows, by way of example, one embodiment of the apparatus which is the subject of the invention.

La fig. 1 est une vue partiellement en eoupe de 1a. Partie principale de 1'appareil. La fig. 2 etant une vue en coupe, ä plus ,(Zrande echelle, de 1'organe de guidage. fig. 1 is a partially sectional view of 1a. Main part of the device. fig. 2 being a cross-sectional view, to a larger scale, of the guide member.

La fig. 3 est une vue de 1'appareil complet en etat de fonetionner. fig. 3 is a view of the complete device in working order.

La fig. 4 montre une variante de 1'organe de guidage. fig. 4 shows a variant of the guide member.

Cet appareil comprend un Organe de trac- tion, en l'occurrence un filin metallique sou- ple 1 et un receptacle 2 destine ä 1e recevoir enroule sur lui-meme. Ce rkeptacle 2 est form4 dune Partie cylindrique 3 accolee ä une Partie troneonique 4 prolongee elle-meme par un tube 5 dans lequel passe 1e filin 1. This device comprises a traction member, in this case a flexible metal cord 1 and a receptacle 2 intended to receive it wound on itself. This receptacle 2 is formed of a cylindrical part 3 attached to a truncated part 4 itself extended by a tube 5 through which the rope 1 passes.

Le receptacle est monte pivotant dans une Partie tubulaire 6 dont est solidaire une en- veloppe conique 7. C'est par cette Partie tubu- laire 6 que 1'appareil doit eire tenu par 1'usa- ger. Une poignee 8 est prevue sur 1e r6cepta- cle 2 pour permettre d'entrainer celui-ei en rotation. De plus, un Organe de serrage cons- titue par une pike filetee 9 est visse dann un alesage taraud,6 transversalement dans 1e tube 5 et dans une bague de renforcement 10 for- c6e sur lui. Il est donc possible, en serrant cette pike filetee 9 eontre 1e film 1 de blo- qu erRTI ID="0001.0274" WI="11" HE="4" LX="1151"LY="1561"> celui-ei dans 1e tube 5 et d'empecher momentanement tont glissement du filin dann 1e tube. The receptacle is pivotally mounted in a tubular part 6 to which is attached a conical casing 7. It is via this tubular part 6 that the device must be held by the user. A handle 8 is provided on the first recepta- cle 2 to allow the latter to be driven in rotation. In addition, a clamping member consisting of a threaded pike 9 is screwed into a tapped bore, 6 transversely in the tube 5 and in a reinforcement ring 10 forced thereon. It is therefore possible, by tightening this threaded pike 9 against the first block film 1 erRTI ID="0001.0274" WI="11" HE="4" LX="1151"LY="1561"> 1st tube 5 and to momentarily prevent the rope from slipping in the 1st tube.

Un Organe de gaidage telescopique est prevu pour guider le filin entre 1'extremite du tube 5 et 1'embouchure 11 du tube dans lequel un ou plusieurs Pils doivent etre tires. A telescopic guide member is provided to guide the rope between the end of the tube 5 and the mouth 11 of the tube in which one or more Pils are to be pulled.

Cet Organe de guidage telescopique com- prend deux tubes 12 et 13 susceptibles de cou- lisser 1'un dans 1'autre. Chaeun des deux tu- bes 12 et 13 pr4sente au voisinage de l'une de ses extremit,6s une butee 14, respective- ment 15. Un ressort ä boudin 16 est enfi1e sur les deux tubes 12 et 13, et en prenant appui sur les butees 14 et 15, tend ä main- tenir 1'organe telescopique dans sa Position d'allongement maximum. Des moyens d'aecroeliage sont prevus pour permettre 1e maintien des tubes 12 et 13 de 1'organe telescopique dans leur Position de moindre eneombrement et ceci eontre 1'aetion du ressort 1.6. Ces moyens sont constitues par un dispositif ä ba:ionnett.e compose d'un teton 17 solidaire du tobe 12 et cl'une encoche 18 du tube 13, 1'en-agement du teton 17 deins 1'encoche 18 empkhant 1e glissement des deux tubes 12 et 13 1'un sur 1'autre. This telescopic guide member comprises two tubes 12 and 13 capable of sliding one inside the other. Each of the two tubes 12 and 13 has near one of its ends a stop 14, respectively 15. A coil spring 16 is threaded over the two tubes 12 and 13, stops 14 and 15, tends to maintain the telescopic member in its position of maximum elongation. Aecroeliage means are provided to allow the first maintenance of the tubes 12 and 13 of the telescopic member in their position of less eneombrement and this eontre 1'aetion of the spring 1.6. These means are constituted by a device ba: ionnett.e consists of a stud 17 secured to the tube 12 and a notch 18 of the tube 13, the arrangement of the stud 17 within the notch 18 preventing the first sliding of the two tubes 12 and 13 on top of each other.

Comme cela est visible ä 1a fig. 2, la bu- tee 15 presente une Partie conique 1.9 dest.i- nee ä. faciliter la mise en plaee de 1'organe de guidage dans 1'embouchure 11 d'un tube de protection. De plus cet.te Partie 19, du Fait de sa forme conique permet 1'utilisation d'un nAme appareil pour des tubes de diametre different. As can be seen in fig. 2, the abutment 15 has a conical part 1.9 intended to. facilitate placing the guide member in the mouth 11 of a protective tube. In addition cet.te Part 19, due to its conical shape allows the use of a nAme device for tubes of different diameters.

En outre, comme 1e montre la fig. 3, sur laquelle 1e receptacle 2 est partiellement coiipe, 1e Fond de celtii-ei presente iuie Partie emboutie 20 au travers de laquelle est fixte une traverse `'1 pouvant seil ir de poignk pour 1e transport de 1'appareil. Further, as shown in FIG. 3, on which the first receptacle 2 is partially coiipe, the first celtii-ei bottom presents iuie stamped part 20 through which is fixed a crosspiece `'1 can seil ir poignk for the first transport of 1'apparatus.

11 y a lieu de roter, d'autre Part, que 1e tobe 12 de 1'organe de guidage a un dianiet.re externe elioisi tel qu'il piiisse etre enfile clans 1'extremite du tube 5. It should be noted, on the other hand, that the tube 12 of the guide member has an external diameter elioisi such that it can be threaded into the end of the tube 5.

L'appareil decrit ei-dessus s'utilise de la maniere suivante: Lorsque Fon veut faire passer des fils dans un tube de proteetion, an tire hors du receptacle une longueur de filin legereinent superieure ä 1a. longueur maximum de 1'or- gane de guidage deploye et Fon bloque 1e filin dans 1e tube 5 ä. 1'aide de 1a. pike 9, an enfile ens2tite 1'organe de gliidage sur 1e filin et an engage 1'extremite du tube 12 dann 1e tube 5. The device described above is used in the following way: When Fon wants to pass son in a protection tube, year pulls out of the receptacle a length of rope slightly greater than 1a. maximum length of the deployed guide member and Fon blocks the rope in the tube 5 ä. the aid of 1a. pike 9, an ens2tite the gliidage member on the first rope and an engages the extremity of the tube 12 in the first tube 5.

La Partie conique 19 de 1'organe de gIti- dage est alors plack dann l'embouehure 11- du tube de protection. 11 suffit alors de pousser 1e receptaele contre 1'action du ressort 16 en Je tenant par la Partie tubulaire 6 tont. en 1e faisant tourner ä 1'aide de la poignee 8 pour engager 1e film 1 dann 1e tube de proteetion. Lorsque la longueur de 1'organe telescopique a ete ramenee ä sa longueur minimum, 1e filin a ete engage dann 1e tube de proteetion sur une distanee approximat.ivement egale ä la diffe rente des lonPieurs de 1'organe teleseopique en Position deployee et en Position de moin- dre eneombrement. The conical part 19 of the gItidage member is then placed in the mouth 11- of the protection tube. 11 then suffices to push the first receptaele against the action of the spring 16 by holding the tubular part 6 tont. by rotating it using the handle 8 to engage the film 1 in the protection tube. When the length of the telescopic member has been reduced to its minimum length, the rope has been engaged in the protection tube over a distance approximately equal to the different lengths of the telescopic member in the deployed position and in the extended position. less congestion.

A ee moment-1ä, an desserre la piece 9 et en retenant 1e filin ä. 1'emlioucliure 11. pour 1'einpeclier de ressortir du tube. on. laisse 1e. ressort 16 se det.endre, ee qui provoque la sor- tie du receptacle 2 dune iiouvell.e longueur de filin.

Repeat the various operations until the end of the end which is provided with a bone 22 appears at the other end. of the protection tube. It is then enough to attach to ball 22 the wires to be passed through the protection tube, to tighten part 9 and to remove all of them. the apparatus of the einbouelmre 1.1. to engage] the son Jans 1st protection tube by removing the 1st rope 1 from eelüi-ei.

Diverses variantes de construetion pour- raient eire prevues pour 1'appareil. Ainsi, 1'organe de gnidage telescopique, au lieu de constituer une pike inclepend < inte du r6cep- tacle, pourrait Former un tont avec lui. 11 suf- firait en effet que 1e tube 5 prolongeant 1e receptacle remplaee lui-menie 1e tube 1.2. Dans ce dernier ras, il serait pi-eferable que 1e tube 13 soit de diametre inferieiir au tube 1.2 et piiisse ainsi eire escamote ä l'intei-ieur du re- ceptaele en Position. de non-einploi de 1'ap- pa.reil. Various constructional variants could be provided for the apparatus. Thus, the telescopic gnidage member, instead of forming an independent pike within the receptacle, could form a tont with it. It would suffice for the first tube 5 extending the replaced receptacle itself to follow the first tube 1.2. In this last ras, it would be pi-eferable that the first tube 13 has a diameter less than the tube 1.2 and thus could be retracted inside the receptacle in position. non-use of the device.

En variante eneore, 1'organe te1eseopique, au lieu de ne comprendre que deux tubes 12 et 13 coulissant 1'un dans 1'autre pourrait en comprendre plus de deux. En outre, en choi- sissant. des tubes 12 et 1.3 coulissant 1'iin dans Pautre avec un certain frottement, i1 serait possible de supprinier Je ressort 16. As a further variant, the telescopic organ, instead of comprising only two tubes 12 and 13 sliding one inside the other, could comprise more than two. Moreover, by choosing. tubes 12 and 1.3 sliding 1'iin in the other with a certain friction, i1 would be possible to remove the spring 16.

D'autre Part, 1e dispositif a baonnette 1.7 et 1.8 pourrait eire supprinie et comme 1e montre la fifg. 4, ce dispositif pourrait etre remplace par wie vis 23 se vissant dann la Partie conique 19 et dort la Pointe viert blo- quer en Position seri ee de 1 a vis, 1e tube 12 dans 1e tube 13. De plus, dans la variante représentée à la fig. 4, la butée 14 présente une gorge 24 dans laquelle est disposée une spire 25 du ressort à boudin 16, cette spire 25 étant de plus petit diamètre que les autres. Une construction semblable pourrait être prévue pour rendre l'autre extrémité du ressort 16 solidaire de la butée 15. On the other hand, the first bayonet device 1.7 and 1.8 could be removed and as shown in fig. 4, this device could be replaced by a screw 23 which is screwed into the conical part 19 and causes the tip to be blocked in the serial position of the screw, the first tube 12 in the first tube 13 Furthermore, in the variant shown in FIG. 4, the abutment 14 has a groove 24 in which is arranged a turn 25 of the coil spring 16, this turn 25 being of smaller diameter than the others. A similar construction could be provided to make the other end of the spring 16 integral with the stop 15.

On pourrait aussi souder les extrémités du ressort 16 sur les butées respectives 14 et 15 pour que les tubes 12 et 1 3 ne puissent pas âtre séparés l'un de l'autre dans la, position d'allongement maximum de l'organe de gui dage télescopique. One could also weld the ends of the spring 16 to the respective stops 14 and 15 so that the tubes 12 and 13 cannot be separated from each other in the position of maximum elongation of the mistletoe member. telescopic pole.

De préférence, le filin 1 est constitué par un fil d'acier enroulé à la facon d'un ressort à. boudin à spires jointives. Il pourrait aussi cure constitué par un câble ou par plusieurs fils d'acier enroulés en hélice les uns dans les autres à. la façon de certains organes de transmission souple, ayant l'allure de plu- sieurs ressorts à boudin de spires de diamètres différents disposées concentriquement les urnes dans les autres. Preferably, the rope 1 consists of a steel wire wound in the manner of a spring. sausage with contiguous turns. It could also cure constituted by a cable or by several steel wires wound helically into each other. the way of certain flexible transmission organs, having the appearance of several coil springs of turns of different diameters arranged concentrically the urns in the others.
