Abstract

For the automatically locking fixing of a guide tube which accommodates a cable transmitting tensile and compressive forces, the guide tube has a projection in the form of a ring - which can also be designed as a threaded ring - and is pushed with its annular region into a longitudinally slotted sleeve. Upon reaching the installation position, the ring is supported with a front end face against a stop face of the sleeve and a rear end face of the ring is grasped from behind by a securing nose positioned in front of the sleeve.

Description

La présente invention concerne un dispositif pour fixer solidement en position, avec verrouillage automatique et possibilité de démontage, un tube de guidage, recevant un câble de transmission de forces de traction et de pression, dans un fourreau fendu longitudinalement au moyen d'une saillie dépassant du tube de guidage et qui s'appuie, lors de son emmanchement dans le fourreau, contre une butée correspondante de celui-ci. The present invention relates to a device for securely fixing in position, with automatic locking and possibility of disassembly, a guide tube, receiving a cable for the transmission of tensile and pressure forces, in a sheath split longitudinally by means of a protrusion projecting of the guide tube and which bears, during its fitting into the sheath, against a corresponding stop thereof.

Une telle fixation d'un tube de guidage est connue d'après la demande de brevet allemand DE-OS 22 32 597, suivant laquelle deux saillies espacées l'une de l'autre dans une direction axiale sont formées par poinçonnage dans le tube de guidage alors que les butées sont réalisées sous forme d'ouverture dans une tôle de fixation reliée au fourreau. La formation des saillies par poinçonnage n'est possible que pour des tubes de guidage qui comportent dans cette zone une fente longitudinale placée dans une position opposée, auquel cas, à cause de la déformation locale, il est nécessaire de faire subir au tube de guidage, non encore pourvu ds câble, un dressage ultérieur. En outre le mode de fixation connu faisant intervenir des zones d'arrêt n'offre pas la garantie qu'une position prédéterminée du tube de guidage est atteinte dans l'opération d'emmanchement. Such fixing of a guide tube is known from German patent application DE-OS 22 32 597, according to which two projections spaced from one another in an axial direction are formed by punching in the tube guide while the stops are made in the form of an opening in a fixing plate connected to the sheath. The formation of protrusions by punching is only possible for guide tubes which have in this zone a longitudinal slot placed in an opposite position, in which case, because of the local deformation, it is necessary to subject the guide tube , not yet fitted with cable, subsequent dressing. In addition, the known method of fixing using stop zones does not guarantee that a predetermined position of the guide tube is reached in the fitting operation.

L'invention a pour but de créer un mode de fixation qui puisse être utilisé également pour des tubes de guidage non fendus et sans opération ultérieure de dressage, et avec lequel on soit assuré que, après terminaison de l'opération d'emmanchement, on obtienne une combinaison prédéterminée du tube de guidage et du fourreau. The object of the invention is to create a fixing method which can also be used for unsplit guide tubes and without subsequent dressing operation, and with which it is ensured that, after completion of the fitting operation, obtains a predetermined combination of the guide tube and the sleeve.

Pour cette raison, il est proposé un dispositif pour fixer solidement en position le tube de guidage d'un câble transmettant des forces de traction et de pression du type précité, qui est caractérisé par la combinaison des propriétés suivantes, en partie connues a) la saillie est agencée sous forme d'une bague placée sur
le tube de guidage, b) une surface frontale de la bague, placée en avant dans
la direction d'emmanchement, s'appuie contre une surface
de butée du fourreau, et c) la surface frontale de la bague, placée en arrière dans
la direction d'emmanchement, s'accroche, à la fin du
processus d'emmanchement, en arrière d'un ergot d'arrêt
placé en avant du fourreau.For this reason, a device is proposed for securely fixing in position the guide tube of a cable transmitting tensile and pressure forces of the aforementioned type, which is characterized by the combination of the following properties, partly known a) the projection is arranged in the form of a ring placed on
the guide tube, b) a front surface of the ring, placed forward in
the direction of fitting, leans against a surface
sleeve stopper, and c) the front surface of the ring, placed behind in
the fitting direction, hangs, at the end of the
fitting process, behind a locking pin
placed in front of the scabbard.

Les frais de montage sont réduits lorsque l'ergot d'arrêt et le fourreau forment une seule et même pièce. The assembly costs are reduced when the locking lug and the sleeve form a single piece.

D'autres avantages concernant la fabrication et le montage sont obtenus lorsque le fourreau et l'ergot d'arrêt sont formés sur une partie de carter constituée de matière plastique. Other advantages concerning the manufacture and the assembly are obtained when the sheath and the lug are formed on a part of casing made of plastic.

Dans un exemple avantageux de réalisation de l'invention, la bague est agencée sous forme d'une bague filetée et elle est pourvue à une extrémité d'un bourrelet qui vient s'appliquer contre un ergot d'arrêt.  In an advantageous embodiment of the invention, the ring is arranged in the form of a threaded ring and it is provided at one end with a bead which comes to bear against a stop lug.

D'autres avantages et caractéristiques de l'invention seront mis en évidence dans la suite de la description, donnée à titre d'exemple non limitatif, en référence au dessin unique annexé qui est une vue en élévation simplifiée, en partie en coupe, d'un mode de réalisation du dispositif selon l'invention. Other advantages and characteristics of the invention will be highlighted in the following description, given by way of nonlimiting example, with reference to the single appended drawing which is a simplified elevation view, partly in section, of 'An embodiment of the device according to the invention.

Un tube-de guidage 2, pourvu d'un filetage extérieur 1, reçoit un câble 3 transmettant des forces de traction et de pression et dont une extrémité libre 4 est profilée sous forme d'une oreille qui est reliée, d'une manière non réprésentée, à un organe d'actionnement ou de manoeuvre. Le filetage extérieur 1 est pourvu d'une saillie 5 qui est agencée sous forme d'une bague filetée 7 comportant un bourrelet 6 à une extrémité. Cette bague 7 est reçue par un fourreau 8 fendu longitudinalement, une surface frontale 9, placée en avant, de la bague 7 s'appuyant contre une surface de butée 10 du fourreau 8. A guide tube 2, provided with an external thread 1, receives a cable 3 transmitting traction and pressure forces and of which a free end 4 is profiled in the form of an ear which is connected, in a non- represented, to an actuating or operating member. The external thread 1 is provided with a projection 5 which is arranged in the form of a threaded ring 7 comprising a bead 6 at one end. This ring 7 is received by a sheath 8 split longitudinally, a front surface 9, placed in front, of the ring 7 pressing against an abutment surface 10 of the sheath 8.

La surface frontale 11, placée en arrière, de la bague 7 s'élargissant dans cette zone par le bourrelet 8, s'accroche, à la fin du processus d'emmanchement, en arrière d'un ergot d'arrêt 12 qui est formé en même temps que le fourreau 8 sur une partie de carter 13, par exemple par moulage par injection. The front surface 11, placed behind, of the ring 7 widening in this zone by the bead 8, hooks, at the end of the fitting process, behind a stop lug 12 which is formed at the same time as the sheath 8 on a casing part 13, for example by injection molding.

Dans l'exemple de réalisation représenté, l'ergot d'arrêt 12 est agencé de façon à être aussi rigide que possible de manière que, lors de l'introduction de la bague 7 dans le fourreau 8, celui-ci s'élargisse temporairement jusqu'à ce que le bourrelet 6 ait passé par dessus la pointe d'ergot d'arrêt 12. In the embodiment shown, the stop lug 12 is arranged to be as rigid as possible so that, when the ring 7 is introduced into the sheath 8, the latter temporarily widens until the bead 6 has passed over the stop pin point 12.

I1 serait naturellement également possible de réaliser l'ergot d'arrêt - formant une seule et même pièce avec le fourreau - de telle sorte que cet ergot d'arrêt s'écarte élastiquement lors du montage et du démontage du tube. I1 would naturally also be possible to produce the stop lug - forming a single piece with the sheath - so that this stop lug deviates elastically during assembly and disassembly of the tube.

Sans sortir du cadre de l'invention, le tube de guidage peut également être réalisé sans filetage et recevoir la bague qui peut alors être agencée sous forme d'un tronçon de tube entourant concentriquement le tube de guidage.  Without departing from the scope of the invention, the guide tube can also be produced without threading and receive the ring which can then be arranged in the form of a tube section concentrically surrounding the guide tube.
