  • the socket 1 in order to facilitate its introduction into the cage as much as possible, also has two other diametrically opposite flats 20C and 20D equivalent to the flats 20A and 20B, which means that even in the most unfavorable initial angular positioning of the socket relative to the cage, it only takes a very small correction to reach an angular position where the socket can be engaged in the cage.
  • Each flat part of the socket 1 has two transverse bosses 21A and 21B each intended to come against one of the transverse edges of the corresponding window (horizontal edges in the figures), in the preassembled state of the stop, as can be seen. seen on the right half-section of figure 1.

  • the sleeve therefore sinks very easily into the cage as long as one remains below the connection zone 23, while beyond this there is a certain resistance due to the additional friction which then appears between the socket and cage.
  • This measure therefore also promotes the convenience of locating the initial position of the sleeve in the cage during assembly of the stop: it suffices to push the sleeve until a blockage is felt to arrive at this initial position. It also makes it possible to do this assembly without forcing too much, while imposing to force when adjusting the stop.

  • This rod is rotatably mounted in the inner tube 6 by being introduced the gripping zone the first in the bore of the inner tube through the orifice 39 which has the inner surface 40 of the bottom of the cage, then by being pressed into this bore until the head 34 comes to bear against the outer surface 40 and that each locking blade 35 and 36 bears against the transverse end surface 25 of the inner tube.
  • the operator when he has adjusted the positioning of elements 4 and 8, simply inserts the tool (here the screwdriver) into the bore of the sleeve 1 from above (as seen in the figure) to slide the tip of its tool into the cavity 38 and maneuver the locking rod, that is to say by making it perform a quarter turn.

It is thus certain that the operator, when he locks the stop, does not remain below or does not go beyond the position in which the end of the cam is engaged in the locking notch 29, and the we are in the same way sure of the initial position of the preassembled state.

Description

La présente invention se rapporte à une butée réglable, utilisable par exemple dans une automobile, entre la caisse et un capot ou une porte de coffre.The present invention relates to an adjustable stop, usable for example in an automobile, between the body and a hood or a trunk door.

On connaît déjà une telle butée réalisée en matière plastique souple, qui comporte pour sa fixation un filet à section carrée destiné à coopérer avec un alésage fileté de la caisse de l'automobile. Le réglage du positionnement de la surface d'arrêt de la butée, qui correspond par exemple à l'alignement d'un capot ou d'une porte de coffre avec d'autres éléments de carrosserie, se fait en faisant tourner la butée, et celle-ci se maintient dans la position dans laquelle on l'a amenée, du fait de la déformation que subit son filet dans le filetage avec lequel celui-ci coopère.There is already known such a stopper made of flexible plastic, which comprises for its fixing a square section net intended to cooperate with a threaded bore of the body of the automobile. The adjustment of the positioning of the stop surface of the stop, which corresponds for example to the alignment of a hood or a trunk door with other bodywork elements, is done by rotating the stop, and it remains in the position in which it was brought, due to the deformation which its thread undergoes in the thread with which it cooperates.

Le réglage de cette butée, c'est-à-dire le réglage du positionnement du capot ou de la porte de coffre par rapport à la caisse, est relativement long, même pour les opérateurs expérimentés. Un certain nombre de tours sont en effet nécessaires, et il est très rare de faire tourner la butée de la bonne quantité du premier coup, un ou plusieurs ajustements sont ensuite nécessaires.The adjustment of this stop, that is to say the adjustment of the positioning of the hood or the trunk door relative to the body, is relatively long, even for experienced operators. A certain number of turns are indeed necessary, and it is very rare to rotate the stopper by the right amount at the first try, one or more adjustments are then necessary.

L'invention vise à fournir une butée qui puisse être réglée plus rapidement. Elle propose à cet effet une butée réglable qui comporte :

  • une douille tubulaire dont une surface transversale annulaire d'extrémité réalise une surface d'arrêt ;
  • une cage munie de moyens de maintien sur un premier élément sur lequel doit être fixée la butée, comportant un tube extérieur et un tube intérieur coaxiaux dont, en section transversale, pour au moins une portion respectivement de la douille et de la cage, le tube intérieur a un contour extérieur similaire au contour de l'alésage de la douille et le tube extérieur un contour d'alésage similaire au contour extérieur de la douille, ladite portion de la cage étant prévue pour loger, entre le tube extérieur et le tube intérieur, ladite portion de la douille ;
  • une tige de blocage destinée à être disposée dans l'alésage du tube intérieur de la cage, comportant avec ce tube intérieur des moyens pour qu'elle y admette une position de verrouillage où elle produit un effort radial destiné à s'appliquer sur la douille pour la bloquer par rapport à la cage, et des moyens pour qu'elle se maintienne dans cette position de verouillage ;

   cette butée étant prévue pour être utilisée dans un état préassemblé où ladite portion de la douille est partiellement insérée entre le tube extérieur et le tube intérieur de ladite portion de la cage en une position initiale à partir de laquelle elle peut s'y enfoncer en coulissant axialement : on met en place la butée sur ledit premier élément sur lequel elle se trouve alors fixée grâce auxdits moyens de maintien de la cage, on amène contre ladite surface d'arrêt de la douille un deuxième élément destiné à venir y porter et on pousse l'un contre l'autre le premier et le deuxième éléments, pour ajuster leur positionnement relatif, ce qui enfonce la douille dans la cage, puis on verrouille la douille dans la cage en amenant la tige de blocage à la position de verrouillage.The invention aims to provide a stop which can be adjusted more quickly. To this end, it offers an adjustable stop which comprises:
  • a tubular bushing, an annular transverse end surface of which forms a stop surface;
  • a cage provided with holding means on a first element to which the stop must be fixed, comprising an outer tube and an inner coaxial tube whose cross section, for at least a portion respectively of the sleeve and of the cage, the tube inner has an outer contour similar to the contour of the bushing bore and the outer tube a bore contour similar to the outer contour of the sleeve, said portion of the cage being designed to accommodate, between the outer tube and the inner tube, said portion of the sleeve;
  • a locking rod intended to be disposed in the bore of the inner tube of the cage, comprising with this inner tube means so that it admits a locking position there where it produces a radial force intended to be applied to the sleeve to block it relative to the cage, and means so that it remains in this locking position;

this stop being intended to be used in a pre-assembled state where said portion of the sleeve is partially inserted between the outer tube and the inner tube of said portion of the cage in an initial position from which it can be inserted therein by sliding axially: the stop is put in place on said first element on which it is then fixed thanks to said means for holding the cage, a second element intended to come to bear thereon is brought against said sleeve stop surface and it is pushed one against the other the first and second elements, to adjust their relative positioning, which pushes the socket into the cage, then the socket is locked in the cage by bringing the locking rod to the locking position.

Ainsi qu'on le voit sur les figures 1 et 2, la butée illustrée comporte conformément à l'invention, une douille tubulaire 1 dont une surface transversale annulaire d'extrémité 2 réalise une surface d'arrêt ; une cage 3 munie de moyens de maintien sur un premier élément 4 - par exemple une caisse de véhicule - sur lequel doit être fixée la butée, comportant un tube extérieur 5 et un tube intérieur 6 coaxiaux dont, en section transversale, pour au moins une portion respectivement de la douille et de la cage, le tube intérieur a un contour extérieur similaire au contour de l'alésage de la douille et le tube extérieur un contour d'alésage similaire au contour extérieur de la douille, ladite portion de la cage étant prévue pour loger, entre le tube extérieur et le tube intérieur, ladite portion de la douille ; et une tige de blocage 7 destinée à être disposée dans l'alésage du tube intérieur 6 de la cage, comportant avec ce tube intérieur des moyens pour qu'elle y admette une position de verrouillage où elle produit un effort radial destiné à s'appliquer sur la douille pour la bloquer par rapport à la cage, et des moyens pour qu'elle se maintienne dans cette position de verrouillage.As seen in Figures 1 and 2, the illustrated stop comprises according to the invention, a tubular sleeve 1, an annular transverse end surface 2 provides a stop surface; a cage 3 provided with holding means on a first element 4 - for example a vehicle body - on which the stop must be fixed, comprising an outer tube 5 and an inner tube 6 coaxial of which, in cross section, for at least one portion respectively of the sleeve and the cage, the inner tube has an outer contour similar to the contour of the bore of the sleeve and the outer tube a bore contour similar to the contour outside of the sleeve, said portion of the cage being designed to accommodate, between the outer tube and the inner tube, said portion of the sleeve; and a locking rod 7 intended to be disposed in the bore of the inner tube 6 of the cage, comprising with this inner tube means so that it admits a locking position where it produces a radial force intended to apply on the sleeve to block it relative to the cage, and means so that it remains in this locked position.

Cette butée est prévue pour être utilisée dans un état préassemblé montré sur la demi-coupe de droite des figure 1 et 2, où ladite portion de la douille 1 est partiellement insérée entre le tube extérieur 5 et le tube intérieur 6 de ladite portion de la cage en une position initiale à partie de laquelle elle peut s'y enfoncer en coulissant axialement : on met en place la butée sur ledit premier élément 4 sur lequel elle se trouve alors fixée grâce auxdits moyens de maintien de la cage, on amène contre la surface d'arrêt 2 de la douille un deuxième élément 8 - par exemple un capot ou une porte de coffre - destiné à venir y porter et on pousse l'un contre l'autre le premier et le deuxième éléments pour ajuster leur positionnement relatif, ce qui enfonce la douille 1 dans la cage 3, puis on verrouille la douille dans la cage en amenant la tige de blocage 7 à la position de verrouillage. La butée se trouve alors dans la position représentée sur la demi-coupe de gauche des figures 1 et 2, si l'on a été jusqu'en position d'enfoncement maximum.This stop is intended to be used in a pre-assembled state shown in the right half-section of FIGS. 1 and 2, where said portion of the sleeve 1 is partially inserted between the outer tube 5 and the inner tube 6 of said portion of the cage in an initial position from which it can be inserted by sliding axially: the stop is put in place on said first element 4 on which it is then fixed thanks to said means for holding the cage, it is brought against the stop surface 2 of the socket a second element 8 - for example a cover or a trunk door - intended to come to carry therein and the first and the second elements are pushed against each other to adjust their relative positioning, which pushes the sleeve 1 into the cage 3, then the sleeve is locked in the cage by bringing the locking rod 7 to the locking position. The stop is then in the position shown in the left half-section of Figures 1 and 2, if one has been up to the maximum driving position.

Dans cet exemple de réalisation, la butée est destinée à être montée par simple insertion dans un orifice de montage 9 du premier élément 4 (voir figure 3). La cage 3 comporte comme moyens de maintien une collerette 10 bordant le tube extérieur à l'opposé du fond 11 de la cage, destinée à venir porter sur le pourtour de l'orifice 9 ; deux lames élastiques de maintien 12A et 12B diamétralement opposées, chacune mobile au travers de la paroi latérale du tube extérieur, adoptant spontanément une position en saillie par rapport à cette paroi latérale, chaque lame étant destinée à venir porter sur ladite paroi du premier élément 4, à l'opposé de la face sur laquelle porte la collerette 10, ainsi qu'on le voit sur la figure 1 ; et un ergot anti-rotation 13 (voir figures 2 et 4) disposé sur la paroi latérale du tube extérieur, destiné à s'engager dans une rainure correspondante 14 de l'orifice 9. L'ergot empêche la rotation de la cage quand on fait tourner la tige de verrouillage pour bloquer la douille dans la cage.In this exemplary embodiment, the stop is intended to be mounted by simple insertion into a mounting orifice 9 of the first element 4 (see FIG. 3). The cage 3 comprises as holding means a flange 10 bordering the outer tube opposite the bottom 11 of the cage, intended to come to bear on the around the orifice 9; two diametrically opposite elastic retaining blades 12A and 12B, each movable through the side wall of the outer tube, spontaneously adopting a projecting position relative to this side wall, each blade being intended to come to bear on said wall of the first element 4 , opposite the face on which the flange 10 bears, as seen in FIG. 1; and an anti-rotation lug 13 (see Figures 2 and 4) disposed on the side wall of the outer tube, intended to engage in a corresponding groove 14 of the orifice 9. The lug prevents the rotation of the cage when rotates the locking rod to lock the socket in the cage.

D'autres types d'immobilisation en rotation sont possibles en variantes à la place de l'ergot, par exemple un orifice 9 prismatique au lieu d'être rond, avec une forme correspondante pour la zone concernée de la cage.Other types of immobilization in rotation are possible in variants in place of the lug, for example a prismatic orifice 9 instead of being round, with a shape corresponding to the concerned zone of the cage.

Les moyens pour que la tige de blocage 7 admette une position de verrouillage comportent :

  • pour le tube intérieur 6 de la cage, deux lames élastiques de verrouillage 15A et 15B diamétralement opposées, chacune mobile au travers de la paroi latérale du tube intérieur, présentant spontanément une saillie intérieure dans l'alésage du tube intérieur (voir la figure 5 et la demi-coupe de droite des figures 1 et 2) ;
  • pour la tige de blocage 7, une came 16 adaptée à coopérer avec ladite saillie intérieure de chacune des lames élastiques 15A et 15B pour, lorsqu'on amène la tige à la position de verrouillage, déplacer la lame élastique vers l'extérieur de façon à ce qu'elle présente une saillie extérieure au tube intérieur, destinée à exercer ledit effort radial sur la douille (voir figures 8, 9 et la demi-coupe de gauche des figures 1 et 2).
The means for the locking rod 7 to admit a locking position comprise:
  • for the inner tube 6 of the cage, two diametrically opposite elastic locking blades 15A and 15B, each movable through the side wall of the inner tube, spontaneously having an internal projection in the bore of the inner tube (see FIG. 5 and the right half-section of Figures 1 and 2);
  • for the locking rod 7, a cam 16 adapted to cooperate with said internal projection of each of the elastic blades 15A and 15B for, when bringing the rod to the locking position, move the elastic blade outward so as to that it has a projection external to the internal tube, intended to exert said radial force on the sleeve (see FIGS. 8, 9 and the left half-cut of FIGS. 1 and 2).

Le tube extérieur 5 présente deux fenêtres diamétralement opposées 18A et 18B en regard chacune d'une des lames de verrouillage 15A et 15B, dans chacune desquelles est destinée à s'engager une portion de la douille déformée par ladite saillie extérieure de chaque lame élastique, ainsi qu'on le voit sur la demi-coupe de gauche des figures 1 et 2.The outer tube 5 has two diametrically opposite windows 18A and 18B opposite each of one of the locking blades 15A and 15B, in each of which is intended to engage a portion of the sleeve deformed by said outer projection of each elastic blade, as seen in the left half-section of Figures 1 and 2.

On a ainsi un verrouillage de la douille dans la cage par engagement de surfaces, plus sûr que par simple appui et adhérence.There is thus a locking of the socket in the cage by engagement of surfaces, safer than by simple support and adhesion.

On a également prévu dans cet exemple des dents transversales acérées 17 sur la partie de chaque lame de verrouillage venant en saillie extérieure, destinées à pénétrer dans la douille, pour améliorer aussi le verrouillage de la douille dans la cage.In this example, sharp transverse teeth 17 have also been provided on the part of each locking blade projecting from the outside, intended to penetrate into the socket, to also improve the locking of the socket in the cage.

Le tube extérieur 5 est cylindrique, mais comporte deux méplats 19A et 19B dans lesquels sont respectivement ménagées la fenêtre 18A et la fenêtre 18B; et sur la douille 1 sont prévus des méplats diamétralement opposés correspondants 20A et 20B.The outer tube 5 is cylindrical, but has two flats 19A and 19B in which the window 18A and the window 18B are respectively provided; and on the socket 1 are provided corresponding diametrically opposite flats 20A and 20B.

Ces méplats présentent l'avantage de réaliser un amincissement de la paroi latérale de la douille qui la rend déformable plus facilement, et sont en outre favorables à l'efficacité du verrouillage de la douille dans la cage, puisque le centre des bords horizontaux de chaque fenêtre (comme on les voit sur les figures) est ainsi rapproché de l'axe de la butée.These flats have the advantage of achieving a thinning of the lateral wall of the sleeve which makes it more easily deformable, and are also favorable to the effectiveness of the locking of the sleeve in the cage, since the center of the horizontal edges of each window (as seen in the figures) is thus brought closer to the axis of the stop.

En fait, afin de faciliter son introduction dans la cage autant que possible, la douille 1 présente également deux autres méplats diamétralement opposés 20C et 20D équivalents aux méplats 20A et 20B, ce qui fait que même dans le positionnement angulaire initial le plus défavorable de la douille par rapport à la cage, il suffit d'une très faible correction pour parvenir à une position angulaire où on peut engager la douille dans la cage.In fact, in order to facilitate its introduction into the cage as much as possible, the socket 1 also has two other diametrically opposite flats 20C and 20D equivalent to the flats 20A and 20B, which means that even in the most unfavorable initial angular positioning of the socket relative to the cage, it only takes a very small correction to reach an angular position where the socket can be engaged in the cage.

Chaque méplat de la douille 1 présente deux bossages transversaux 21A et 21B destinés à venir chacun contre l'un des bords transversaux de la fenêtre correspondante (bords horizontaux sur les figures), à l'état préassemblé de la butée, ainsi qu'on le voit sur la demi-coupe de droite de la figure 1.Each flat part of the socket 1 has two transverse bosses 21A and 21B each intended to come against one of the transverse edges of the corresponding window (horizontal edges in the figures), in the preassembled state of the stop, as can be seen. seen on the right half-section of figure 1.

Cela facilite le repérage de la position initiale de la douille dans la cage lors du préassemblage de la butée, ainsi que le maintien de la douille dans la position initiale.This facilitates the identification of the initial position of the sleeve in the cage during the pre-assembly of the stop, as well as the maintenance of the sleeve in the initial position.

On notera que les méplats 20A et 20C de la douille s'étendent à partir de son extrémité 22 par laquelle elle est enfoncée dans la cage jusqu'à une zone de raccordement 23 dont l'emplacement est prévu pour correspondre à la limite d'insertion de la douille dans la cage, dans la position initiale correspondant à l'état préassemblée de la butée (voir la demi-coupe de droite de la figure 1). La douille s'enfonce donc très facilement dans la cage tant qu'on reste en-deçà de la zone de raccordement 23, tandis qu'au-delà de celle-ci se manifeste une certaine résistance due au frottement supplémentaire qui apparaît alors entre la douille et la cage.It will be noted that the flats 20A and 20C of the sleeve extend from its end 22 by which it is pressed into the cage to a connection zone 23 whose location is provided to correspond to the insertion limit of the sleeve in the cage, in the initial position corresponding to the pre-assembled state of the stop (see the right half-section in Figure 1). The sleeve therefore sinks very easily into the cage as long as one remains below the connection zone 23, while beyond this there is a certain resistance due to the additional friction which then appears between the socket and cage.

Cette mesure favorise donc aussi la commodité du repérage de la position initiale de la douille dans la cage lors de l'assemblage de la butée : il suffit d'enfoncer la douille jusqu'à ressentir un blocage pour arriver à cette position initiale. Elle permet en outre de faire cet assemblage sans trop forcer, tout en imposant de forcer lors du réglage de la butée.This measure therefore also promotes the convenience of locating the initial position of the sleeve in the cage during assembly of the stop: it suffices to push the sleeve until a blockage is felt to arrive at this initial position. It also makes it possible to do this assembly without forcing too much, while imposing to force when adjusting the stop.

La came 16 de la tige de blocage 7 est effilée et s'étend radialement de part et d'autre de l'axe de la tige (c'est-à-dire diamétralement), cette tige étant prévue pour être amenée par rotation à la position de verrouillage de la douille dans la cage : à l'état préassemblé de la butée, la came 16 se loge entre les saillies intérieures des lames 15A et 15B sans agir sur celles-ci (voir les demi-coupes de droite des figures 1 et 2), mais lorsqu'on la tourne elle pousse les lames vers l'extérieur (voir les demi-coupes de gauche des figures 1 et 2).The cam 16 of the locking rod 7 is tapered and extends radially on either side of the axis of the rod (that is to say diametrically), this rod being designed to be brought by rotation to the locking position of the sleeve in the cage: in the pre-assembled state of the stop, the cam 16 is housed between the internal projections of the blades 15A and 15B without acting on these (see the right half-cuts of Figures 1 and 2), but when it is turned it pushes the blades outwards (see the left half-cuts of Figures 1 and 2).

Dans cet exemple de réalisation, les moyens pour que la tige de blocage 7 se maintienne dans la position de verrouillage comportent un cran de verrouillage 29 ménagé dans chaque lame de verrouillage 15A et 15B (voir figures 2 et 5) suivant une direction axiale, destiné à loger l'extrémité de la came effilée 16 pour immobiliser en rotation la tige de verrouillage.In this exemplary embodiment, the means for the locking rod 7 to remain in the locking position comprise a locking notch 29 formed in each locking blade 15A and 15B (see FIGS. 2 and 5) in an axial direction, intended housing the end of the tapered cam 16 to immobilize the locking rod in rotation.

Le tube intérieur 6 est moins long que le tube extérieur 5 et comporte un alésage cylindrique, et la tige de blocage comporte :

  • un corps 30 destiné à être logé dans l'alésage du tube intérieur 6, comportant la came effilée 16 et au moins une surface de guidage en rotation de la tige par rapport au tube intérieur, ici les extrémités des nervures 31 et les surfaces cylindriques étroites 32 et 33 situées de part et d'autre de la came 16 ;
  • une tête transversale 34 située à une première extrémité du corps 30 ;
  • à une seconde extrémité de celui-ci, distante de la première extrémité d'une distance similaire à la longueur du tube intérieur, deux lames élastiques de blocage 35 et 36 mobiles chacune radialement et adoptant spontanément une position en saillie par rapport au corps 30 ;
  • une zone de préhension 37 prolongeant la tige 7 au-delà de cette seconde extrémité, présentant en bout une empreinte 38 pour un outil destiné à faire tourner la tige de blocage, ici pour un tournevis à lame plate.
The inner tube 6 is shorter than the outer tube 5 and has a cylindrical bore, and the locking rod comprises:
  • a body 30 intended to be housed in the bore of the inner tube 6, comprising the tapered cam 16 and at least one surface for guiding the rod in rotation relative to the inner tube, here the ends of the ribs 31 and the narrow cylindrical surfaces 32 and 33 located on either side of the cam 16;
  • a transverse head 34 located at a first end of the body 30;
  • at a second end thereof, distant from the first end by a distance similar to the length of the inner tube, two elastic locking blades 35 and 36 each movable radially and spontaneously adopting a projecting position relative to the body 30;
  • a gripping zone 37 extending the rod 7 beyond this second end, having at the end an imprint 38 for a tool intended to rotate the locking rod, here for a flat blade screwdriver.

Cette tige est montée à rotation dans le tube intérieur 6 en étant introduite zone de préhension la première dans l'alésage du tube intérieur par l'orifice 39 que présente la surface intérieure 40 du fond de la cage, puis en étant enfoncé dans cet alésage jusqu'à ce que la tête 34 vienne porter contre la surface extérieure 40 et que chaque lame de blocage 35 et 36 porte contre la surface transversale d'extrémité 25 du tube intérieur.This rod is rotatably mounted in the inner tube 6 by being introduced the gripping zone the first in the bore of the inner tube through the orifice 39 which has the inner surface 40 of the bottom of the cage, then by being pressed into this bore until the head 34 comes to bear against the outer surface 40 and that each locking blade 35 and 36 bears against the transverse end surface 25 of the inner tube.

On notera que la douille, du fait des bossages 21A et 21B, ainsi que la tige de blocage, grace à la tête 34 et aux lames 35 et 36, sont imperdables à l'état préassemblé.Note that the sleeve, due to the bosses 21A and 21B, as well as the locking rod, thanks to the head 34 and to the blades 35 and 36, are captive in the pre-assembled state.

L'opérateur, lorsqu'il a ajusté le positionnement des éléments 4 et 8, insère simplement l'outil (ici le tournevis) dans l'alésage de la douille 1 par le dessus (tel qu'on la voit sur la figure) pour glisser le bout de son outil dans l'empreinte 38 et manoeuvrer la tige de blocage, c'est-à-dire en lui faisant effectuer un quart de tour. La douille est alors verrouillée à la position à laquelle elle a été ajustée.The operator, when he has adjusted the positioning of elements 4 and 8, simply inserts the tool (here the screwdriver) into the bore of the sleeve 1 from above (as seen in the figure) to slide the tip of its tool into the cavity 38 and maneuver the locking rod, that is to say by making it perform a quarter turn. The socket is then locked in the position to which it was adjusted.

La surface extérieure 40 du fond de la cage présente un ergot 41, et la tête 34 deux surfaces de butée 42 et 43 destinées à limiter le débattement de la tige de blocage par venue en butée contre l'ergot 41, respectivement lorsque la tige de blocage est dans la position angulaire d'attente et lorsqu'elle est en position de verrouillage. On est ainsi sûr que l'opérateur, lorsqu'il verrouille la butée, ne reste pas en deça ou ne va pas au delà de la position dans laquelle l'extrémité de la came est engagée dans le cran de blocage 29, et l'on est de la même façon sûr de la position initiale de l'état préassemblé.The outer surface 40 of the bottom of the cage has a lug 41, and the head 34 two abutment surfaces 42 and 43 intended to limit the movement of the locking rod by coming into abutment against the lug 41, respectively when the rod blocking is in the angular waiting position and when it is in the locking position. It is thus certain that the operator, when he locks the stop, does not remain below or does not go beyond the position in which the end of the cam is engaged in the locking notch 29, and the we are in the same way sure of the initial position of the preassembled state.

La figure 11 montre une variante 3A de la cage de la butée, où les lames 15A et 15B sont remplacées par des lames comparables 44A et 44B diamétralement opposées qui sont articulées en partie haute au lieu de l'être en partie basse, et qui ne comportent pas de dents 17.Figure 11 shows a variant 3A of the stop cage, where the blades 15A and 15B are replaced by comparable blades 44A and 44B diametrically opposed which are articulated in the upper part instead of being in the lower part, and which do not have no teeth 17.

La figure 12 illustre une variante 1A de la douille tubulaire de la butée, qui n'est plus monobloc, mais comporte un corps de douille 50 et un écrou de douille 51 coopérant coaxialement l'un avec l'autre par un filetage dont la section est visible sur le demi-coupe de gauche, et dont on a représenté l'hélice primitive 52 pour l'ensemble de la figure. C'est la surface 2A de l'écrou 51 qui porte dans cette variante la surface annulaire d'extrémité qui réalise une surface d'arrêt.FIG. 12 illustrates a variant 1A of the tubular sleeve of the stop, which is no longer in one piece, but comprises a sleeve body 50 and a nut sleeve 51 cooperating coaxially with each other by a thread whose section is visible on the left half-section, and of which the primitive propeller 52 has been shown for the whole of the figure. It is the surface 2A of the nut 51 which in this variant carries the annular end surface which produces a stop surface.

Le corps 50 et l'écrou 51 sont dans la configuration de vissage maximum de l'écrou représentée sur la figure à l'état préassemblé de la butée. Lorsque la douille 1A a été verrouillée dans la cage de la même façon que la douille 1, un réglage fin supplémentaire de la position de la surface d'arrêt est possible, en faisant tourner l'écrou 51 par rapport au corps 50 grace à l'empreinte de manoeuvre 53.The body 50 and the nut 51 are in the maximum screwing configuration of the nut shown in the figure in the pre-assembled state of the stop. When the socket 1A has been locked in the cage in the same way as the socket 1, an additional fine adjustment of the position of the stop surface is possible, by turning the nut 51 relative to the body 50 thanks to the maneuver footprint 53.

Le corps 50 et l'écrou 51 sont tous deux réalisés en matière souple, et le blocage de l'un par rapport à l'autre se fait par déformation de leur filetage.The body 50 and the nut 51 are both made of flexible material, and the blocking of one with respect to the other is done by deformation of their thread.

Les cages 3 et 3 A sont en matière relativement dure alors que les douilles 1 et 1A sont en matière souple. La douille 1 comporte sur sa paroi latérale, à proximité de la surface d'arrêt 2, des rainures annulaires d'assouplissement 27 et 28 (voir figure 6), ce qui lui confère une fonction d'amortisseur entre lesdits premier et deuxième éléments 4 et 8 pour les chocs dus à leur rencontre, mais aussi pour les vibrations. De telles rainures sont envisageables si nécessaire sur l'écrou 51 de la douille 1A.The cages 3 and 3 A are made of relatively hard material while the sockets 1 and 1A are made of flexible material. The socket 1 has on its side wall, near the stop surface 2, annular softening grooves 27 and 28 (see FIG. 6), which gives it a damper function between said first and second elements 4 and 8 for the shocks due to their meeting, but also for the vibrations. Such grooves can be envisaged if necessary on the nut 51 of the socket 1A.

On notera que si l'on a prévu dans l'exemple illustré, diamétralement opposés, pour des raisons d'équilibre, deux lames 15A et 15B, deux méplats 19A et 19B et deux lames de maintien 35 et 36, un ou une seule d'entre-eux ou d'entre-elles pourrait être suffisant dans d'autres modes de réalisation de l'invention ; et que la came 16 pourrait alors simplement s'étendre radialement au lieu de diamétralement.It will be noted that if provision has been made in the illustrated example, diametrically opposite, for reasons of balance, two blades 15A and 15B, two flats 19A and 19B and two holding blades 35 and 36, one or only one d 'between them or between them could be sufficient in other embodiments of the invention; and that the cam 16 could then simply extend radially instead of diametrically.
