- the distance between two supporting cheeks is likely to vary depending on the constraints encountered at the time even the installation of the roller shutter.
- the axis section, on which the winding shaft is rotatably mounted, its end opposite to the drive means is of the type telescopic. More specifically, the protruding length of this section of axis relative to the end of the winding shaft is adjustable, thus making it possible to make up for dimensional differences encountered.
- This telescopic mounting of such a section of axis on which is mounted in rotation of the roller shutter winding shaft also has a another advantage, namely that it considerably facilitates the installation of said roller shutter. Indeed, we can, therefore, consider a nesting axial of the entire mechanism on the supporting cheeks beforehand fixed on masonry or other.

- the present invention relates, more particularly, to the field of roller shutters.
- a rolling shutter comprises, as shown in FIG. 1, a shaft 1 on which is wound and from which a apron (not shown) consisting of a juxtaposition of blades articulated with respect to each other.

- Such supporting cheeks 4, 5 can still be attached to the upper end of side rails having for the purpose of guiding the roller shutter deck during its movements.
- the present invention relates, more particularly, to the case shown in Figure 1, i.e. in a situation where the tree winding 1 comprises motorized drive means 6 located at one of its ends 3 and whose opposite end 2 is rotatably mounted on a section of axis 7, the end portion 8 is fixed on the cheek support 4.
- the motorized drive means 6 can present themselves, as shown schematically in this figure 1, under form of a tubular motor 9 introduced, in a known manner, into the end 3 of the winding shaft 1. In addition, this is maintained in rotation, at this end 3 by means of a bearing 10 made secured to the support cheek 5.
- this tree winding 1 is rotatably mounted on a section of axis 7, this by through two internal bearings 11, 12, also known as tandem in the profession. In fact, they allow mounting telescopic of said axis section 7 relative to the winding shaft 1.
- the first 11 of these bearings, located at the very end of the winding shaft 1 is immobilized in translation relative to this last while it is sliding on the axis section 7.
- the second internal bearing 12 slides inside this shaft winding 1.
- This telescopic quality of the axis section 7 is particularly appreciable since not only does it compensate for possible variations in distance between the supporting cheeks 4, 5, but, in in addition, it facilitates the mounting and installation of the roller shutter.
- the present invention relates to a fixing device 14 of the winding shaft 1 on said support cheeks 4, 5, which responds to advantageously to the constraints which have been presented above.
- this fixing device 14 is intended to be able to resolve the problem of fixing the end part 8 of the axis section 7 on the cheek support 4 authorizing this cooperation of the control means emergency 13 with said winding shaft 1.
- this fastening device 14 uses retractable connecting means 15, more particularly illustrated in FIG. 2, and which comprise, in particular, an attached tubular endpiece 16, by welding or by via an appropriate base, on the support cheek 4.
- This tubular endpiece 16 has a bore 17 adjusted to the diameter 18 of the axis section 7 allowing it to receive the end portion 8 of this latest.

- said retaining means 19 are presented under form of at least one tongue 21 extending radially around the periphery of this end portion 8 of the axis section 7.
- axial cutouts 22 are made in the end 23 of the axis section 7 so as to define a tongue 21 which is then folded radially outwards from the tube corresponding to this section of axis 7. It appears, obviously, that such a design is simple and inexpensive to produce.

More precisely, the assembly of the circlip 28 carried out, it comes position at the front of the tongue or tongues 21, engaged in the one or more grooves 24 and oppose, in this way, the release of these tongues 21 with respect to said grooves 24.
- the grooves 24 are, in fact, machined cutouts in the thickness of the wall 25 of the tubular endpiece 16 allowing the tabs 21, the length of which is provided accordingly, to have projecting peripheries 30 of said tubular end piece 16.
- the circlip 28 comes immobilize perfectly, the axis section 7 axially in the end piece tubular 16.
- the groove or grooves 24 in the wall 25 of the tubular endpiece 16 do not open out periphery 30 of the latter, while the tongues 21 are themselves shorter length adjusted to the depth of the grooves 24.
- the circlips 28 then comes to be housed in a groove at the periphery of the tubular endpiece 16, groove which opens into the axial grooves 24 so that once the circlip 28 is in position, it can, effectively, oppose the withdrawal of said tabs 21 corresponding to the sections of axis 7 of these axial grooves 24 of the tubular endpiece 16.

Description
L'invention a trait à un dispositif de fixation d'un arbre de volet roulant dont au moins une extrémité est montée en rotation sur un tronçon d'axe télescopique rendu solidaire d'une joue support à l'aide de moyens de liaison escamotables, tel que décrit par exemple dans EP-A-0 320 423.The invention relates to a device for fixing a roller shutter shaft. at least one end of which is rotatably mounted on a section of telescopic axis made integral with a support cheek using means retractable link, as described for example in EP-A-0 320 423.
La présente invention trouvera son application dans le domaine des volets roulants.The present invention will find its application in the field of roller shutters.
D'une manière habituelle, un volet roulant pour porte, fenêtre ou analogue, comporte un arbre sur lequel et duquel s'enroule et se déroule un tablier constitué par une juxtaposition de lames reliées les unes aux autres à l'aide de moyens d'articulation appropriés. Cet arbre d'enroulement dudit tablier est monté en rotation sur des tronçons d'axe qui se présentent saillants à ses extrémités et sont fixés sur des joues supports. Celles-ci peuvent être rapportées sur la maçonnerie ou encore sur l'extrémité supérieure de coulisses contribuant au guidage du tablier lors de ses déplacements.Usually, a rolling shutter for door, window or analogous, has a tree on which and which is wound and unwound an apron constituted by a juxtaposition of blades connected to each other others using appropriate means of articulation. This tree of winding of said deck is rotatably mounted on sections of axis which protrude at its ends and are fixed on cheeks supports. These can be added to the masonry or on the upper end of slides contributing to guiding the deck while traveling.
Sur l'une des extrémités d'un tel arbre d'enroulement sont montés, en outre, les moyens d'entraínement en rotation qui peuvent être du type manuel, tels qu'une poulie, un treuil ou analogue, ou encore du type à commande électrique. Tout particulièrement, il est connu, pour l'entraínement de tels volets roulants, des moteurs tubulaires qui sont engagés dans cette extrémité de l'arbre d'enroulement en vue d'en assurer la rotation par l'intermédiaire de moyens de transmission appropriés. En fait, la présence même de tels moyens d'entraínement, quelles que soient leurs caractéristiques, fait en sorte que la cote, entre la joue support et l'extrémité, proprement dite, de l'arbre d'enroulement, est figée. Toutefois, la distance séparant deux joues supports est, elle, susceptible de varier en fonction des contraintes rencontrées au moment même de la pose du volet roulant. C'est pour cela que, très souvent, le tronçon d'axe, sur lequel est monté en rotation l'arbre d'enroulement, à son extrémité opposée aux moyens d'entraínement, est du type télescopique. Plus précisément, la longueur saillante de ce tronçon d'axe par rapport à l'extrémité de l'arbre d'enroulement est ajustable, permettant, ainsi, de rattraper les différences dimensionnelles rencontrées.On one end of such a winding shaft are mounted, in in addition, the rotary drive means which can be of the type manual, such as a pulley, winch or the like, or of the type with online order. In particular, it is known, for the drive of such roller shutters, tubular motors which are engaged in this end of the winding shaft in order to rotate through transmission means appropriate. In fact, the very presence of such training means, whatever their characteristics, makes the rating between the supporting cheek and the end, proper, of the winding shaft, is frozen. However, the distance between two supporting cheeks is likely to vary depending on the constraints encountered at the time even the installation of the roller shutter. This is why, very often, the axis section, on which the winding shaft is rotatably mounted, its end opposite to the drive means, is of the type telescopic. More specifically, the protruding length of this section of axis relative to the end of the winding shaft is adjustable, thus making it possible to make up for dimensional differences encountered.
Ce montage télescopique d'un tel tronçon d'axe sur lequel est monté en rotation l'arbre d'enroulement du volet roulant, présente, également, un autre intérêt, à savoir qu'il facilite, considérablement, la pose dudit volet roulant. En effet, l'on peut, de ce fait, envisager un emboítement axial de l'ensemble du mécanisme sur les joues supports préalablement fixées sur la maçonnerie ou autre.This telescopic mounting of such a section of axis on which is mounted in rotation of the roller shutter winding shaft, also has a another advantage, namely that it considerably facilitates the installation of said roller shutter. Indeed, we can, therefore, consider a nesting axial of the entire mechanism on the supporting cheeks beforehand fixed on masonry or other.
A ce propos, la fixation de l'extrémité libre d'un tel tronçon d'axe sur une joue support s'effectue, essentiellement, de la manière suivante : cette extrémité libre du tronçon d'axe constitué, substantiellement, par un tube, est, soit positionnée dans un berceau, soit engagée dans une douille équipant la joue support. L'extrémité du tube définissant ce tronçon d'axe comporte, de manière diamétralement opposée, des ouvertures que l'on vient positionner au droit d'ouvertures ménagées au niveau du berceau ou de ladite douille en vue d'engager une goupille de blocage. Celle-ci est ensuite déformée de manière à ce qu'elle ne s'échappe involontairement. Il est également usuel d'aménager dans le fond d'un berceau venant équiper la joue support, une dent, analogue à une goupille que l'on vient insérer dans les ouvertures traversant, de manière diamétralement opposée, l'extrémité du tronçon d'axe.In this regard, the fixing of the free end of such a section of axis on a support cheek is carried out, essentially, in the following way: this free end of the section of axis formed, substantially, by a tube, is either positioned in a cradle, or engaged in a socket fitted to the support cheek. The end of the tube defining this axis section comprises, diametrically opposite, openings that are just positioned to the right of openings made at level of the cradle or of said socket in order to engage a locking pin blocking. This is then deformed so that it does not escapes involuntarily. It is also customary to arrange in the bottom of a cradle from the supporting cheek, a tooth, similar to a pin which is inserted into the through openings, diametrically opposite, the end of the axis section.
Le problème que pose, précisément, un tel montage, s'observe, plus particulièrement, dans le cas d'un entraínement motorisé du volet roulant. En effet, l'obstruction procurée par la goupille, immobilisant en translation et en rotation par rapport à la joue support, le tronçon d'axe situé à l'extrémité de l'arbre d'enroulement, opposée par rapport aux moyens moteurs, empêche l'aménagement de toute commande de secours. Aussi, il est très fréquent de ne pas équiper, pour ces raisons, un volet roulant motorisé de moyens d'entraínement de secours.The problem posed, precisely, by such an arrangement is observed, more particularly in the case of a motorized shutter drive rolling. Indeed, the obstruction provided by the pin, immobilizing in translation and rotation relative to the support cheek, the axis section located at the end of the winding shaft, opposite to the motor means, prevents the development of any control relief. Also, it is very common not to equip, for these reasons, a motorized roller shutter with emergency drive means.
A ce propos, il faut toutefois observer que l'on a déjà imaginé, par le passé, d'équiper la joue support d'un palier tubulaire, sous forme d'une pièce en matière plastique, sur lequel est directement montée l'extrémité de l'arbre d'enroulement. Par ailleurs, au travers de ce palier tubulaire, l'on vient insérer, dans ledit arbre d'enroulement, un arbre de transmission qui peut être entraíné en rotation par des moyens manuels du type treuil, poulie ou analogue. Cet arbre de transmission retransmet son mouvement audit arbre d'enroulement, soit d'une manière directe, soit au travers d'un différentiel de configuration appropriée.In this regard, however, it should be noted that we have already imagined, by passed, to equip the support cheek with a tubular bearing, in the form of a plastic part, on which is directly mounted the end of the winding shaft. In addition, through this level tubular, we just insert, in said winding shaft, a shaft transmission which can be rotated by manual means of the winch, pulley or similar type. This transmission shaft retransmits its movement to said winding shaft, either directly, either through an appropriate configuration differential.
L'on voit, immédiatement, l'inconvénient majeur d'une telle construction, à savoir qu'il y a absence totale, dans ces conditions, de moyens d'ajustement axial de l'arbre d'enroulement par rapport à la position des joues supports. En effet, la présence du palier tubulaire sur lequel est monté l'arbre d'enroulement impose, bien évidemment, la suppression du tronçon d'axe télescopique. En outre, du côté opposé, c'est-à-dire du côté motorisation, tout moyen d'ajustement axial n'est guère envisageable.We immediately see the major disadvantage of such a construction, namely that there is a total absence, under these conditions, of means of axial adjustment of the winding shaft relative to the position of the supporting cheeks. Indeed, the presence of the tubular bearing on which is mounted the winding shaft imposes, of course, the elimination of the telescopic axis section. Also, on the opposite side, that is to say on the motorization side, any means of axial adjustment is not hardly possible.
Finalement, la présente invention a pour but d'apporter une solution au problème précité, c'est-à-dire une solution qui permette d'envisager l'équipement d'un volet roulant motorisé d'une commande de secours, sans que cela ne remette en cause la présence d'un tronçon d'axe télescopique à l'extrémité opposée de l'arbre d'enroulement, ceci par rapport à ladite motorisation.Finally, the present invention aims to provide a solution to the aforementioned problem, that is to say a solution which makes it possible to envisage equipping a motorized roller shutter with an emergency control, without jeopardizing the presence of an axis section telescopic to the opposite end of the winding shaft, this by compared to said engine.
L'invention, telle qu'elle est caractérisée dans les revendications, résout le problème et consiste en un dispositif de fixation d'un arbre de volet roulant dont au moins une extrémité est montée en rotation sur un tronçon d'axe télescopique rendu solidaire d'une joue support à l'aide de moyens de liaison escamotables, ces moyens de liaison escamotables étant constitués, en combinaison, par :
- un embout tubulaire comportant un alésage ajusté au diamètre du tronçon d'axe pour recevoir la partie d'extrémité de ce dernier ;
- des moyens de retenue aménagés en périphérie de cette partie d'extrémité dudit tronçon d'axe qui en assurent le blocage en rotation lorsqu'ils sont amenés à coopérer avec des moyens de retenue complémentaires équipant la paroi de l'embout tubulaire.
- et des moyens de blocage axial, de nature escamotable, de ladite partie d'extrémité du tronçon d'axe dans l'embout tubulaire, sous forme de moyens de verrouillage s'opposant au dégagement des moyens de retenue correspondant au tronçon d'axe par rapport aux moyens de retenue complémentaires associés à l'embout tubulaire.
- a tubular end piece having a bore adjusted to the diameter of the axis section to receive the end portion of the latter;
- retaining means arranged at the periphery of this end part of said section of axis which ensure its rotation lock when they are brought to cooperate with complementary retaining means equipping the wall of the tubular endpiece.
- and axial locking means, of retractable nature, of said end portion of the axis section in the tubular end piece, in the form of locking means opposing the release of the retaining means corresponding to the axis section by compared to the additional retaining means associated with the tubular end piece.
Selon un mode de réalisation préférentiel, les moyens de retenue aménagés en périphérie de la partie d'extrémité du tronçon d'axe se présentent sous forme d'au moins une languette s'étendant, radialement, en périphérie de ce tronçon d'axe, tandis que les moyens de retenue complémentaires sont constitués par au moins une rainure usinée axialement dans la paroi de l'embout tubulaire et débouchant à l'extrémité libre de ce dernier.According to a preferred embodiment, the retaining means arranged at the periphery of the end part of the axis section is have in the form of at least one tongue extending radially, at the periphery of this section of axis, while the retaining means complementary are constituted by at least one machined groove axially in the wall of the tubular end piece and opening out the free end of the latter.
Quant aux moyens de blocage axial, ils sont conçus, préférentiellement, sous forme d'un circlips à même d'être engagé au-dessus de l'embout tubulaire associé à la joue support en vue de verrouiller l'ergot ou la languette s'étendant, radialement, par rapport au tronçon d'axe, dans ladite rainure axiale aménagée dans la paroi de cet embout tubulaire. As for the axial locking means, they are preferably designed, in the form of a circlip capable of being engaged above the end piece tubular associated with the support cheek in order to lock the lug or the tongue extending radially with respect to the axis section in said axial groove arranged in the wall of this tubular end piece.
Les avantages découlant de la présente invention consistent, essentiellement, en ce qu'aucun organe des moyens de liaison escamotables, conforme à l'invention, ne vient entraver le passage d'un arbre de transmission correspondant à une manoeuvre de secours à l'intérieur du tronçon d'axe sur lequel est monté en rotation l'arbre d'enroulement du tablier. Par ailleurs, ce tronçon d'axe est à même de conserver sa propriété télescopique par rapport à l'extrémité de l'arbre d'enroulement, tel que cela apparaítra plus en avant dans la description qui va suivre.The advantages arising from the present invention consist, basically, in that no organ connecting means retractable, according to the invention, does not hinder the passage of a drive shaft corresponding to an emergency operation at inside the axis section on which the shaft is rotatably mounted curtain winding. Furthermore, this section of axis is able to keep its telescopic property relative to the end of the tree winding, as will appear further in the description who will follow.
Ainsi, cette invention est exposée plus en détail dans cette description se rapportant au dessin joint en annexe représentant seulement un mode d'exécution.

La présente invention concerne, plus particulièrement, le domaine des
volets roulants. Ainsi, un tel volet roulant comporte, tel que représenté
dans la figure 1, un arbre 1 sur lequel s'enroule et duquel se déroule un
tablier (non représenté) constitué par une juxtaposition de lames
articulées les unes par rapport aux autres. The present invention relates, more particularly, to the field of
roller shutters. Thus, such a rolling shutter comprises, as shown
in FIG. 1, a
Cet arbre 1, dénommé dans la suite de la description arbre
d'enroulement, est maintenu en rotation, à ses extrémités 2, 3, par des
joues supports 4, 5 lesquelles peuvent être rendues solidaires de la
maçonnerie, au niveau d'une embrasure aménagée dans une habitation
et correspondant à une porte, fenêtre ou analogue destinée à accueillir,
précisément, le volet roulant. De telles joues supports 4, 5 peuvent
encore être fixées sur l'extrémité supérieure de coulisses latérales ayant
pour but de guider le tablier du volet roulant lors de ses déplacements.
Ces coulisses latérales n'ont pas été représentées sur le dessin ci-joint
s'agissant d'éléments parfaitement connus par l'Homme du Métier.This
La présente invention s'attache, plus particulièrement, au cas de figure
représenté dans la figure 1, c'est-à-dire dans une situation où l'arbre
d'enroulement 1 comporte des moyens d'entraínement motorisés 6 se
situant à l'une de ses extrémités 3 et dont l'extrémité opposée 2 est
montée en rotation sur un tronçon d'axe 7 dont la partie d'extrémité 8
vient se fixer sur la joue support 4.The present invention relates, more particularly, to the case
shown in Figure 1, i.e. in a situation where the tree
winding 1 comprises motorized drive means 6
located at one of its
Tout particulièrement, les moyens d'entraínement motorisés 6 peuvent
se présenter, tels que représentés schématisés dans cette figure 1, sous
forme d'un moteur tubulaire 9 introduit, de manière connue, dans
l'extrémité 3 de l'arbre d'enroulement 1. De plus, celui-ci est maintenu
en rotation, à cette extrémité 3 par l'intermédiaire d'un palier 10 rendu
solidaire de la joue support 5.In particular, the motorized drive means 6 can
present themselves, as shown schematically in this figure 1, under
form of a tubular motor 9 introduced, in a known manner, into
the
A son extrémité opposée 2, comme déjà indiqué ci-dessus, cet arbre
d'enroulement 1 est monté en rotation sur un tronçon d'axe 7, ceci par
l'intermédiaire de deux paliers internes 11, 12, encore dénommés
tandem dans la profession. En fait, ils permettent un montage
télescopique dudit tronçon d'axe 7 par rapport à l'arbre d'enroulement 1.
Ainsi, le premier 11 de ces paliers, se situant à l'extrémité même de
l'arbre d'enroulement 1, est immobilisé en translation par rapport à ce
dernier tandis qu'il est coulissant sur le tronçon d'axe 7. Contrairement,
le second palier interne 12 coulisse à l'intérieur de cet arbre
d'enroulement 1.At its
Cette qualité télescopique du tronçon d'axe 7 est particulièrement appréciable puisque non seulement elle permet de compenser les variations de distance possibles entre les joues supports 4, 5, mais, en outre, elle facilite le montage et la pose du volet roulant.This telescopic quality of the axis section 7 is particularly appreciable since not only does it compensate for possible variations in distance between the supporting cheeks 4, 5, but, in in addition, it facilitates the mounting and installation of the roller shutter.
Dans une telle configuration correspondant à un volet roulant motorisé,
il est souhaitable de disposer de moyens de manoeuvre de secours 13
qui, en raison de l'encombrement procuré par les moyens
d'entraínement motorisés 6 à l'extrémité 3 de l'arbre d'enroulement 1,
ne peuvent intervenir qu'au niveau de l'extrémité opposée 2 de ce
dernier.In such a configuration corresponding to a motorized roller shutter,
it is desirable to have emergency maneuvering means 13
which, due to the space provided by the means

En fait, la présente invention concerne un dispositif de fixation 14 de
l'arbre d'enroulement 1 sur lesdites joues supports 4, 5, qui répond de
manière avantageuse aux contraintes qui ont été présentées plus haut.
Ainsi, ce dispositif de fixation 14 se veut à même de résoudre le
problème de la fixation de la partie d'extrémité 8 du tronçon d'axe 7 sur
la joue support 4 autorisant cette coopération des moyens de commande
de secours 13 avec ledit arbre d'enroulement 1. Dans ce but, ce
dispositif de fixation 14 fait appel à des moyens de liaison escamotables
15, plus particulièrement illustrés dans la figure 2, et qui comportent,
notamment, un embout tubulaire 16 rapporté, par soudure ou par
l'intermédiaire d'une embase appropriée, sur la joue support 4. Cet
embout tubulaire 16 comporte un alésage 17 ajusté au diamètre 18 du
tronçon d'axe 7 lui permettant de recevoir la partie d'extrémité 8 de ce
dernier.In fact, the present invention relates to a
Ces moyens de liaison escamotables 15 se distinguent, en outre, par des
moyens de retenue 19 aménagés en périphérie de cette partie
d'extrémité 8 du tronçon d'axe 7 et ayant pour fonction d'assurer le
blocage en rotation de ce dernier lorsqu'ils sont amenés à coopérer avec
des moyens de retenue complémentaires 20 équipant l'embout tubulaire
16.These retractable connecting means 15 are further distinguished by
retaining
Préférentiellement, lesdits moyens de retenue 19 se présentent sous
forme d'au moins une languette 21 s'étendant radialement en périphérie
de cette partie d'extrémité 8 du tronçon d'axe 7. Tout particulièrement,
celui-ci étant du type tubulaire, des découpes axiales 22 sont réalisées
dans l'extrémité 23 du tronçon d'axe 7 de manière à délimiter une
languette 21 qui est alors repliée radialement vers l'extérieur du tube
correspondant à ce tronçon d'axe 7. Il apparaít, de manière évidente,
qu'une telle conception est de réalisation simple et peu coûteuse.Preferably, said retaining means 19 are presented under
form of at least one
Préférentiellement, deux languettes 21 s'étendant radialement et de
manière diamétralement opposée par rapport à la partie d'extrémité 8 du
tronçon d'axe 7, définissent lesdits moyens de retenue 19.Preferably, two
Quant aux moyens de retenue complémentaires 20, ils se présentent
sous forme d'au moins une rainure 24 aménagée, axialement, dans la
paroi 25 de l'embout tubulaire 16 tout en débouchant à l'extrémité libre
26 de ce dernier. Cette ou ces rainures 24 sont disposées, au niveau de
cet embout tubulaire 16, en concordance avec la ou les languettes 21 du
tronçon d'axe 7, permettant l'emboítement.As for the additional retaining means 20, they arise
in the form of at least one
Conformément à l'invention, les moyens de liaison escamotables 15 sont
complétés par des moyens de blocage axial 27, de nature escamotable,
dudit tronçon d'axe 7 dans l'embout tubulaire 16. Avantageusement, ces
moyens de blocage axial 27 ce présentent sous forme de moyens de
verrouillage empêchant le retrait de la ou des languettes 21, définissant
les moyens de retenue 19, de la ou des rainures 24 correspondant aux
moyens de retenue complémentaires 20. According to the invention, the retractable connecting
Ainsi, selon un mode de réalisation préférentiel, ces moyens de blocage
axial 27 sont constitués par un circlips 28 à même d'être engagé sur
l'embout tubulaire 16, à l'arrière d'organes de retenue 29 empêchant le
dégagement axial de ce circlips 28 à l'extrémité libre 26 de cet embout
tubulaire 16. Dans ces conditions, ce circlips 28 vient, simultanément,
empêcher le dégagement des moyens de retenue 19 par rapport aux
moyens de retenue complémentaires 20 lorsque la partie de l'extrémité
8 du tronçon d'axe 7 est engagée dans l'embout tubulaire 16. Plus
précisément, le montage du circlips 28 effectué, celui-ci vient se
positionner à l'avant de la ou des languettes 21, engagées dans la ou les
rainures 24 et s'opposer, de cette manière, au dégagement de ces
languettes 21 par rapport auxdites rainures 24.Thus, according to a preferred embodiment, these blocking means
axial 27 are constituted by a
Selon un premier mode d'exécution, plus particulièrement illustré dans
le dessin ci-joint, les rainures 24 sont, en fait, des découpes usinées
dans l'épaisseur de la paroi 25 de l'embout tubulaire 16 permettant aux
languettes 21, dont la longueur est prévue en conséquence, de se
présenter saillantes en périphérie 30 dudit embout tubulaire 16. Ainsi,
en venant se positionner entre les organes de retenue 29 et ces
languettes saillantes 21 insérées dans les rainures 24, le circlips 28 vient
immobiliser parfaitement, le tronçon d'axe 7 axialement dans l'embout
tubulaire 16. Selon un second mode d'exécution, la ou les rainures 24
dans la paroi 25 de l'embout tubulaire 16, ne débouchent pas en
périphérie 30 de ce dernier, tandis que les languettes 21 sont, elles, de
longueur plus réduite ajustées à la profondeur des rainures 24. Le
circlips 28 vient, alors, se loger dans une rainure en périphérie de
l'embout tubulaire 16, rainure qui débouche dans les rainures axiales 24
de sorte qu'une fois le circlips 28 en position, il puisse, effectivement,
s'opposer au retrait desdites languettes 21 correspondant aux tronçons
d'axe 7 de ces rainures axiales 24 de l'embout tubulaire 16.According to a first embodiment, more particularly illustrated in
the attached drawing, the
Les avantages qui découlent de cette invention consistent, bien entendu,
en ce que, tel que représenté dans les figures 1 et 3, rien ne s'oppose,
intérieurement au tronçon d'axe 7, de forme tubulaire, au passage d'un
arbre de transmission 31 correspondant à des moyens de manoeuvre de
secours 13 permettant d'entraíner manuellement l'arbre d'enroulement 1
en cas de défaillance du moteur électrique. A noter, à ce propos, que
l'arbre de transmission 31 peut retransmettre son mouvement de
rotation à l'arbre d'enroulement 1, soit directement, soit par
l'intermédiaire d'un différentiel ou encore de moyens analogues.The advantages which flow from this invention consist, of course,
in that, as shown in FIGS. 1 and 3, nothing stands in the way,
internally to the section of axis 7, of tubular shape, when a
