Abstract

The winder for the strap (2) of a shutter includes a strap winding and tensioning part (3) located inside a casing formed from two shells (4, 8). Each shell comprises an edge frame (44, 84) extending in a direction perpendicular to a principal shell web (41, 81). These edge frames are mutually engaged by a relative translation in a direction parallel to the respective webs so that the edge of the first shell is surrounded by that of the second shell. The external surface (44 a) of the first edge has reliefs (44 b) which engage corresponding reliefs (84 b) in the internal surface of the second edge.

Description

L'invention a trait à un enrouleur de sangle, à un mécanisme de manoeuvre d'un volet, store roulant ou analogue comprenant un tel enrouleur et à un procédé de fabrication d'un tel enrouleur.The invention relates to a strap winder, operating mechanism for a shutter, roller blind or the like comprising such a reel and a method of manufacturing a such reel.

Il est connu d'utiliser une courroie, une sangle ou tout autre lien flexible pour la manoeuvre d'un volet ou store roulant et, plus généralement, pour tout dispositif comprenant un tablier apte à être sélectivement enroulé sur un arbre pour obturer ou non une ouverture, telle qu'une fenêtre ou une porte de bâtiment.It is known to use a strap, a strap or any another flexible link for operating a shutter or blind rolling and, more generally, for any device comprising an apron capable of being selectively wound on a tree for whether or not to block an opening, such as a window or door of building.

Afin d'éviter qu'une telle courroie ou sangle ne pende en direction du sol, notamment en configuration enroulée du tablier, il est prévu de disposer un enrouleur de sangle à proximité d'une telle ouverture, cet enrouleur comprenant un organe de tension de cette sangle par enroulement automatique à l'intérieur de l'enrouleur. Ainsi, EP-A-0 812 795 divulgue un enrouleur de sangle comprenant un boítier à ressorts disposé à l'intérieur d'un corps formé de deux coques articulées autour d'une charnière et prévues pour s'encliqueter l'une avec l'autre par rotation autour de l'axe de cette charnière. En position montée de cet enrouleur, il demeure une fente de raccord entre ces deux coques, la largeur de cette fente ne pouvant être contrôlée avec précision du fait des tolérances de fabrication habituelles pour ce genre de dispositif. Des salissures ont tendance à s'accumuler dans cette fente, ce qui est à la fois inesthétique et potentiellement pathogène. En outre, un tel enrouleur, qui est disposé à proximité d'une ouverture, est soumis à des variations de température d'amplitude importante, notamment en fonction de son exposition au soleil. Il n'est pas rare que les coques qui sont soumises à des contraintes thermiques différentes selon leur exposition se déforment à un point tel que la fente précitée baille, ce qui augmente les inconvénients précités. Enfin, la réalisation d'une charnière nécessite un outillage complexe et majore sensiblement le prix de revient du boítier de l'enrouleur connu.To prevent such a strap or strap from hanging down ground direction, especially in the rolled configuration of the apron, it is planned to have a strap winder proximity of such an opening, this reel comprising a tensioning member of this strap by automatic winding inside the reel. Thus, EP-A-0 812 795 discloses a strap winder comprising a spring box arranged at the interior of a body formed by two shells hinged around of a hinge and provided to snap one with the other by rotation around the axis of this hinge. In mounted position of this reel, there remains a slot connection between these two shells, the width of this slot does not can be precisely controlled due to tolerances usual manufacturing for this kind of device. of the dirt tends to accumulate in this slot, which is both unsightly and potentially pathogenic. In in addition, such a reel, which is arranged near a opening, is subject to amplitude temperature variations important, in particular according to its exposure to Sun. It is not uncommon for hulls that are subjected to different thermal stresses depending on their exposure distort to such an extent that the aforementioned slot yawns, which increases the aforementioned drawbacks. Finally, the realization a hinge requires complex and larger tools substantially the cost price of the reel housing known.

C'est à ces inconvénients qu'entend plus particulièrement remédier l'invention en proposant un enrouleur de sangle dont le boítier est formé de façon simple, donc fiable, et sans création d'une fente disgracieuse dans laquelle peuvent s'accumuler des salissures.It is to these disadvantages that we hear more particularly remedy the invention by proposing a strap winder, the housing is formed in a simple way, therefore reliable, and without creating an unsightly slit in which can accumulate dirt.

Dans cet esprit, l'invention concerne un enrouleur de sangle ou analogue pour la manoeuvre d'un volet, store roulant ou équivalent, cet enrouleur comprenant un organe d'enroulement et de tension de la sangle disposé à l'intérieur d'un boítier formé de deux coques comprenant chacune au moins une bordure s'étendant selon une direction globalement perpendiculaire à un voile principal de chaque coque, caractérisé en ce que ces bordures sont aptes à être amenées en engagement mutuel par une translation relative selon une direction globalement parallèle aux voiles principaux respectifs des coques, dans une configuration où une première bordure d'une première coque est entourée par une seconde bordure de la seconde coque.In this spirit, the invention relates to a winder strap or the like for operating a shutter, roller blind or equivalent, this reel comprising a winding member and tension of the strap arranged inside a case formed of two shells each comprising at least one border extending in a direction generally perpendicular to a main sail of each hull, characterized in that these curbs are capable of being brought into mutual engagement by a relative translation in a generally parallel direction to the respective main sails of the hulls, in a configuration where a first border of a first shell is surrounded by a second border of the second shell.

Grâce à l'invention, il n'est pas nécessaire d'utiliser une charnière pour l'assemblage du boítier de l'enrouleur. D'autre part, comme une bordure entoure l'autre bordure en configuration assemblée, la surface extérieure de la bordure externe forme une surface apparente uniforme du boítier, sans fente ou ouverture.Thanks to the invention, it is not necessary to use a hinge for assembling the housing of the reel. On the other hand, as a border surrounds the other border in assembled configuration, the outer surface of the border external form a uniform apparent surface of the case, without slot or opening.

Selon des caractéristiques avantageuses de l'invention, l'enrouleur incorpore une ou plusieurs des caractéristiques suivantes :

  • Les bordures s'étendent chacune selon au moins deux directions globalement perpendiculaires. Ceci permet d'obtenir une immobilisation relative des deux coques par coopération de formes des bordures, parallèlement à ces deux directions.
  • La surface externe de la première bordure est pourvue de reliefs aptes à coopérer avec des reliefs correspondants formés sur la surface interne de la seconde bordure pour l'assemblage des coques. Ces reliefs, qui peuvent comprendre des rainures et collerettes de profils correspondants, permettent une mise en prise des bordures suffisante pour éviter un déboítement des coques.
  • Les coques ont un bord sensiblement rectiligne et un bord concave dont la concavité est tournée, en configuration assemblée du boítier, vers l'organe de tension, les bordures s'étendant, au niveau de ce bord concave, sur un secteur angulaire d'angle au sommet supérieur ou égal à 180°.
  • L'une des coques comprend une seconde bordure s'étendant selon la direction globalement perpendiculaire à la direction de translation relative des coques et pourvue d'au moins un logement de réception d'un pion porté par l'autre coque. Ceci permet d'obtenir une immobilisation relative supplémentaire des deux coques formant le boítier.
  • L'une des coques porte un verrou élastique apte à coopérer avec une partie correspondante de l'autre coque pour verrouiller les coques en configuration assemblées du boítier. Dans ce cas, ce verrou est avantageusement formé sur un bord de la coque prévu pour être orienté vers une cloison au voisinage de laquelle est apte à être monté l'enrouleur, ce verrou étant masqué par l'enrouleur en position normale d'utilisation. Grâce à cet aspect de l'invention, le verrou n'est pas directement accessible pour un utilisateur qui n'en connaít pas l'existence, par exemple un enfant, alors qu'un professionnel peut y accéder en faisant pivoter l'enrouleur ou en glissant ses doigts entre l'enrouleur et la cloison. On peut en outre prévoir que le verrou est formé par une languette élastiquement déformable s'étendant selon une direction globalement perpendiculaire à la direction de translation relative des coques.
According to advantageous characteristics of the invention, the reel incorporates one or more of the following characteristics:
  • The borders each extend in at least two generally perpendicular directions. This makes it possible to obtain a relative immobilization of the two shells by cooperation of the shapes of the edges, parallel to these two directions.
  • The external surface of the first border is provided with reliefs able to cooperate with corresponding reliefs formed on the internal surface of the second border for the assembly of the shells. These reliefs, which may include grooves and flanges of corresponding profiles, allow engagement of the edges sufficient to avoid dislocation of the shells.
  • The shells have a substantially straight edge and a concave edge, the concavity of which is turned, in the assembled configuration of the housing, towards the tension member, the edges extending, at this concave edge, over an angular sector of angle at the top greater than or equal to 180 °.
  • One of the shells comprises a second edge extending in the direction generally perpendicular to the direction of relative translation of the shells and provided with at least one housing for receiving a pin carried by the other shell. This allows to obtain an additional relative immobilization of the two shells forming the housing.
  • One of the shells carries an elastic lock capable of cooperating with a corresponding part of the other shell to lock the shells in the assembled configuration of the housing. In this case, this lock is advantageously formed on an edge of the shell intended to be oriented towards a partition in the vicinity of which is adapted to be mounted the reel, this lock being masked by the reel in the normal position of use. Thanks to this aspect of the invention, the lock is not directly accessible for a user who does not know its existence, for example a child, while a professional can access it by rotating the reel or by sliding his fingers between the reel and the partition. It can also be provided that the lock is formed by an elastically deformable tongue extending in a direction generally perpendicular to the direction of relative translation of the shells.

L'invention concerne également un mécanisme de manoeuvre d'un volet, store roulant ou équivalent qui comprend un enrouleur de sangle tel que précédemment décrit. Un tel mécanisme de manoeuvre est plus économique et plus facile à installer que les dispositifs connus.The invention also relates to an operating mechanism a shutter, roller blind or equivalent which includes a strap winder as previously described. Such operating mechanism is more economical and easier to install only known devices.

L'invention concerne enfin un procédé de fabrication d'un enrouleur tel que précédemment décrit et, plus spécifiquement, un procédé qui consiste à:

  • mouler deux coques pourvues chacune d'un voile principal et d'une bordure s'étendant selon une direction globalement perpendiculaire à ce voile ;
  • équiper l'une de ces coques d'éléments de fixation et/ou d'un frein pour la sangle, notamment par rivetage ;
  • assembler les coques en leur faisant subir un mouvement de translation relative selon une direction globalement parallèle à leurs voiles principaux respectifs et
  • verrouiller les coques ensemble par coopération de formes des bordures.
Finally, the invention relates to a method for manufacturing a reel as described above and, more specifically, to a method which consists in:
  • molding two shells each provided with a main veil and a border extending in a direction generally perpendicular to this veil;
  • equip one of these shells with fastening elements and / or a brake for the strap, in particular by riveting;
  • assemble the hulls by subjecting them to a relative translational movement in a direction generally parallel to their respective main sails and
  • lock the hulls together by cooperation of border shapes.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaítront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un enrouleur de sangle conforme à son principe, donnée uniquement à titre d'exemple et faite en référence aux dessins annexés dans lesquels :

L'enrouleur 1 1 représenté sur les figures est destiné à maintenir tendue une sangle 2 de manoeuvre de l'arbre d'enroulement d'un volet ou store roulant non représenté. Une boíte à ressorts 3 est prévue pour exercer sur la courroie 2 un effort élastique tendant à enrouler la sangle 2 autour de la boíte 3 dans le sens de la flèche R à la figure 1.The reel 1 1 shown in the figures is intended for keep a tensioning strap 2 for handling the winding shaft a shutter or roller blind not shown. A box springs 3 is provided to exert on the belt 2 a force elastic tending to wrap the strap 2 around the box 3 in the direction of arrow R in Figure 1.

La boíte 3 est montée sur une coque en matière plastique 4 comportant un voile principal 41 dans la partie centrale de laquelle est formé, de façon monobloc, un axe 42 de centrage de la boíte 3. Le voile 41 comprend un bord sensiblement rectiligne 41a et un bord concave 41b dont la concavité est tournée vers l'axe 42 et la boíte 3.The box 3 is mounted on a plastic shell 4 comprising a main veil 41 in the central part of which is formed, in a single piece, an axis 42 for centering the box 3. The veil 41 comprises a substantially rectilinear edge 41 a and a concave edge 41 b whose concavity is turned towards the axis 42 and the box 3.

Au niveau du bord 41a, le voile 41 se prolonge par une bordure 43 globalement rectiligne et perpendiculaire au voile 41. De la même manière, une bordure 44 s'étend au niveau du bord 41b du voile 41 en étant perpendiculaire à ce voile, les bordures 43 et 44 s'étendant du même côté par rapport au voile 41.At the edge 41a, the sail 41 is extended by a generally straight and perpendicular 43 to the web edge 41. Similarly, an edge 44 extends at the edge 41b of the web 41 being perpendicular to the veil , the edges 43 and 44 extending on the same side relative to the web 41.

La bordure 43 est pourvue de deux orifices allongés 43a globalement parallèles au bord 41a. Une languette 43b est également formée dans la bordure 43 grâce à deux fentes 43c globalement perpendiculaires au bord 41a. La surface externe de la languette 43b, c'est-à-dire sa surface tournée à l'opposé de la boíte 3, est pourvue de cannelures ou stries 43d.The edge 43 is provided with two elongated orifices 43 a generally parallel to the edge 41 a . A tongue 43 b is also formed in the border 43 by virtue of two slots 43 c generally perpendicular to the edge 41 a . The outer surface of the tongue 43 b , that is to say its surface facing away from the box 3, is provided with grooves or ridges 43 d .

La surface externe 44a de la bordure 44 est pourvue d'une rainure 44b globalement parallèle au bord 41b du voile principal 41.The external surface 44 a of the edge 44 is provided with a groove 44 b generally parallel to the edge 41 b of the main web 41.

A proximité de la bordure 43, la bordure 44 s'élargit et forme deux pattes 44c sur lesquelles sont rivetées des équerres 5 permettant le montage de l'enrouleur 1 sur une cloison verticale grâce à des vis représentées par leurs traits d'axes respectifs 6. Un frein 7 est également monté en partie supérieure de la bordure 43 et contre la patte supérieure 44c de la bordure 44 en étant riveté sur la patte 44c avec l'équerre 5 correspondante. Le frein 7 comprend une came 7a articulée autour d'un axe 7b et apte à coopérer avec ce second axe 7c pour coincer la sangle 2 lorsque celle-ci s'étend selon une direction globalement verticale, comme représenté à la figure 1.Near the edge 43, the edge 44 widens and forms two tabs 44 c on which are fastened brackets 5 allowing the mounting of the reel 1 on a vertical partition by means of screws represented by their respective axes lines 6. A brake 7 is also mounted in the upper part of the edge 43 and against the upper tab 44 c of the edge 44 while being riveted on the tab 44 c with the corresponding bracket 5. The brake 7 comprises a cam 7a articulated around an axis 7b and able to cooperate with this second axis 7c to wedge the strap 2 when the latter extends in a generally vertical direction, as shown in FIG. 1.

L'ensemble des éléments 3 à 7, qui sont portés par la coque 4, permet le fonctionnement de l'enrouleur, ces éléments 3 et 7 devant être protégés de l'atmosphère environnante.All of elements 3 to 7, which are carried by the shell 4, allows the operation of the reel, these elements 3 and 7 to be protected from the surrounding atmosphere.

Pour ce faire, une autre coque 8 est réalisée en matière plastique et comprend un voile principal 81 de forme analogue au voile 41 et comprenant également un bord rectiligne 81a et un bord concave 81b. Le bord 81a du voile 81 est pourvu de deux pions 83a de forme allongée correspondant à celle des orifices 43a. Un retour 83b de faible dimension s'étend transversalement par rapport au bord 81a dans la partie centrale de celui-ci. Le bord concave 81b du voile 81 porte une bordure 84 s'étendant selon une direction globalement perpendiculaire au voile 81 sur la plus grande partie du bord 81b.To do this, another shell 8 is made of plastic and comprises a main veil 81 similar in shape to the veil 41 and also comprising a straight edge 81 a and a concave edge 81 b . The edge 81 a of the web 81 is provided with two pins 83 a of elongated shape corresponding to that of the orifices 43 a . A return 83 b of small dimension extends transversely with respect to the edge 81 a in the central part thereof. The concave edge 81 b of the web 81 carries a rim 84 extending in a direction generally perpendicular to the web 81 over the greater part of the edge 81b.

La surface interne 84a de la surface 84, c'est-à-dire la surface tournée vers le voile 81, est pourvue d'une nervure 84b dont le profil correspond à celui de la rainure 44b de la bordure 44. En fait, et comme il ressort de la figure 5, les profils des surfaces 44a et 84a sont complémentaires.The internal surface 84 a of the surface 84, that is to say the surface facing the web 81, is provided with a rib 84 b whose profile corresponds to that of the groove 44 b of the edge 44. In fact, and as is apparent from Figure 5, the profiles of the surfaces 44 a and 84 a are complementary.

Conformément à l'invention, la coque 8 est prévue pour être montée sur la coque 4 par un mouvement de translation parallèle aux voiles 41 et 81, et représenté par la flèche F1 à la figure 1. Ce mouvement a pour effet de rapprocher les bords 41a et 81a d'une part, 41b et 81b d'autre part, la bordure 84 venant entourer la bordure 44 au point qu'elle masque pratiquement complètement cette bordure, comme représenté à la figure 2.According to the invention, the shell 8 is designed to be mounted on the shell 4 by a translational movement parallel to the sails 41 and 81, and represented by the arrow F 1 in FIG. 1. This movement has the effect of bringing the edges 41 a and 81 a on the one hand, 41 b and 81 b on the other hand, the border 84 coming to surround the border 44 to the point that it practically completely hides this border, as shown in FIG. 2.

Dans la position montée de la figure 2, l'enrouleur constitue un ensemble fermé et les pions 83a ont pénétré dans les orifices 43a alors que la languette 43b a été dépassée par le retour 83b, de telle sorte qu'elle est coincée à l'intérieur de ce retour.In the assembled position of FIG. 2, the reel constitutes a closed assembly and the pins 83 a have penetrated into the orifices 43 a while the tongue 43 b has been passed by the return 83 b , so that it is stuck inside this return.

Comme il ressort plus particulièrement de la comparaison des figures 3 et 4, la rainure 44b et la nervure 84b coopèrent pour guider le mouvement de translation selon la flèche F1, comme représenté à la figure 4 et verrouiller efficacement ensemble les bordures 44 et 84, comme représenté dans la position de la figure 3.As appears more particularly from the comparison of FIGS. 3 and 4, the groove 44 b and the rib 84 b cooperate to guide the translational movement according to arrow F 1 , as shown in FIG. 4 and effectively lock the edges 44 and 84, as shown in the position of Figure 3.

La coopération des profils des surfaces 44a et 84a est plus particulièrement visible à la figure 5.The cooperation of the profiles of the surfaces 44 a and 84 a is more particularly visible in FIG. 5.

Les bords 41b et 81b des voiles principaux s'étendent selon une direction X globalement parallèle à la flèche F1 et selon une direction Y globalement perpendiculaire à cette flèche. Ainsi, les bordures 44 et 84 s'étendent selon deux directions, de telle sorte que lorsque l'une d'entre elles est en appui contre l'autre, on obtient une immobilisation relative des coques 4 et 8, à la fois selon les directions X et Y. En d'autres termes, le caractère non rectiligne des bordures 44 et 84 assure une bonne immobilisation des coques 4 et 8 l'une par rapport à l'autre.The edges 41 b and 81 b of the main webs extend in a direction X generally parallel to the arrow F 1 and in a direction Y generally perpendicular to this arrow. Thus, the edges 44 and 84 extend in two directions, so that when one of them is in abutment against the other, a relative immobilization of the shells 4 and 8 is obtained, both according to the directions X and Y. In other words, the non-rectilinear nature of the edges 44 and 84 ensures good immobilization of the shells 4 and 8 relative to each other.

Les bordures 44 et 84 s'étendent autour de l'axe 42 sur un secteur angulaire d'angle au sommet α de l'ordre de 220°, ce qui signifie que la coopération de formes de ces bordures a lieu sur plus de la moitié de la circonférence du boítier ainsi formé, vu de l'axe 42.The edges 44 and 84 extend around the axis 42 on a angular sector of angle at the top α of the order of 220 °, this which means that the cooperation of shapes of these borders has place over more than half the circumference of the case as well formed, seen from axis 42.

Comme il ressort plus clairement de la figure 6, les pions 83a du bord 81a s'engagent dans les orifices 43a de la bordure 43, ce qui permet d'éviter une ouverture intempestive du boítier formé des coques 4 et 8 entre le bord libre 43e de la bordure 43 et le bord 81a. Les pions 83a empêchent ainsi une déformation vers l'intérieur du bord 81a en configuration montée de l'enrouleur.As can be seen more clearly from FIG. 6, the pins 83 a from the edge 81 a engage in the orifices 43 a from the edge 43, which makes it possible to avoid inadvertent opening of the housing formed by the shells 4 and 8 between the free edge 43 e from edge 43 and edge 81 a . The pins 83 a thus prevent deformation towards the inside of the edge 81 a in the mounted configuration of the reel.

Comme il ressort de la figure 7, un bec 43f de la languette 43 est prévu pour dépasser le retour 83b grâce à une face chanfreinée tournée vers l'intérieur de la coque 4. Dans cette position, la languette 43 joue le rôle d'un verrou élastique, car elle s'oppose à un mouvement de la coque 8 dans le sens opposé à la flèche F1.As can be seen in FIG. 7, a spout 43 f of the tongue 43 is provided to exceed the return 83 b thanks to a chamfered face facing the inside of the shell 4. In this position, the tongue 43 plays the role of 'an elastic lock, because it opposes a movement of the shell 8 in the opposite direction to the arrow F 1 .

Lorsqu'il est nécessaire d'ouvrir le boítier formé des coques 4 et 8, il suffit d'exercer sur la languette 43b un effort, représenté par la flèche F2 à la figure 7, tel que la languette 43b atteint la position représentée en traits mixtes dans laquelle le bec 43f ne s'oppose plus au mouvement de translation F3 de la coque 8.When it is necessary to open the housing formed by the shells 4 and 8, it suffices to exert on the tongue 43 b a force, represented by the arrow F 2 in FIG. 7, such that the tongue 43 b reaches the position represented in phantom in which the spout 43 f no longer opposes the translational movement F 3 of the shell 8.

L'assemblage de l'enrouleur 1 peut être réalisé de façon automatique dans la mesure où le rivetage des équerres 5 et du frein 7 sur les pattes 44c peut être réalisé par un premier manipulateur, alors que l'armement et la mise en place de la boíte 3 sur l'axe 42 peut également être automatisé. La seconde coque 8 est alors mise en place sur la coque 4 et l'enrouleur peut être conditionné et expédié.The assembly of the reel 1 can be carried out automatically insofar as the riveting of the brackets 5 and of the brake 7 on the lugs 44 c can be carried out by a first manipulator, while the arming and the positioning of the box 3 on the axis 42 can also be automated. The second shell 8 is then placed on the shell 4 and the reel can be packaged and shipped.

Sur le site de pose, l'utilisateur fixe l'enrouleur sur le dormant d'une ouverture grâce aux équerres 5 et dégage la coque 8 pour accéder à la boíte à ressorts 3. Il suffit alors de solidariser l'extrémité inférieure de la sangle 2 avec la boíte 3 et de retirer une agrafe 9 d'immobilisation de cette boíte avant de faire glisser la coque 8 selon la direction de la flèche F1 pour fermer le boítier formé des coques 4 et 8, la fin du mouvement de la coque 8 résultant dans un verrouillage du boítier en configuration fermée par coopération de formes des éléments 43a, 43b, 83a et 83b.On the installation site, the user fixes the reel on the frame with an opening using the brackets 5 and releases the shell 8 to access the spring box 3. It then suffices to secure the lower end of the strap 2 with the box 3 and remove a clip 9 immobilizing this box before sliding the shell 8 in the direction of the arrow F 1 to close the housing formed of the shells 4 and 8, the end of the movement of the hull 8 resulting in a locking of the housing in the closed configuration by cooperation of shapes of the elements 43 a , 43 b , 83 a and 83 b .

Compte tenu de l'orientation habituelle des équerres 5, la bordure 43 de la coque 4 est destinée à être tournée vers la cloison contre laquelle est monté l'enrouleur 1. Ceci a pour conséquence que la languette 43b et les orifices 43a ne sont pas immédiatement accessibles, notamment pour un enfant, ce qui évite les risques d'une ouverture non autorisée. Lorsqu'un professionnel souhaite ouvrir le boítier formé des coques 4 et 8, il lui suffit de faire pivoter la coque 4 autour de l'articulation formée par les rivets de fixation des équerres 5 pour accéder à la languette 43b sur laquelle il peut exercer un effort d'effacement du bec 43f, tel que représenté par la flèche F2 à la figure 7.Given the usual orientation of the brackets 5, the edge 43 of the shell 4 is intended to be turned towards the partition against which the reel 1 is mounted. This has the consequence that the tongue 43 b and the orifices 43 a do not are not immediately accessible, especially for a child, which avoids the risks of unauthorized opening. When a professional wishes to open the case formed by the shells 4 and 8, it suffices to rotate the shell 4 around the articulation formed by the fixing rivets of the brackets 5 to access the tongue 43 b on which he can exercise an effort to erase the spout 43 f , as represented by the arrow F 2 in FIG. 7.

L'invention a été représentée avec la coque 4 portant le verrou élastique 43b. Cependant, un tel verrou pourrait être prévu sur la coque 8 sans sortir du cadre de la présente invention.The invention has been shown with the shell 4 carrying the elastic lock 43 b . However, such a lock could be provided on the shell 8 without departing from the scope of the present invention.

Dans tous les cas, l'enrouleur de l'invention a une esthétique harmonieuse sans fente susceptible de s'ouvrir au niveau de sa tranche et avec une bonne tenue de l'assemblage dans le temps, alors que les deux coques utilisées s'obtiennent aisément par moulage sans utilisation de moules complexes, tels que des moules à tiroir. Enfin, l'enrouleur de l'invention peut être assemblé de façon automatique, ce qui permet de diminuer sensiblement son prix de revient.In all cases, the reel of the invention has a harmonious aesthetic without slit likely to open at level of its edge and with good strength of the assembly in time, while the two shells used are obtained easily by molding without the use of complex molds, such as drawer molds. Finally, the reel of the invention can be assembled automatically, which reduces substantially its cost price.
