Description

L'invention est relative à un enrouleur notamment destiné à recevoir une sangle de manoeuvre d'un volet roulant.The invention relates to a reel in particular intended to receive an operating strap for a roller shutter.

Un volet roulant est constitué par un tablier qui vient s'enrouler autour d'un tambour, entraîné en rotation au moyen d'une manivelle ou d'une sangle. Dans le cas particulier d'un volet roulant manoeuvré par une sangle, celle-ci est animée d'un mouvement de va-et-vient entre deux positions extrêmes qui correspondent l'une à la position haute, l'autre à la position basse du tablier. L'extrémité libre de la sangle est fixée de préférence sur un enrouleur, qui présente des moyens de tension, permettant d'enrouler la sangle sur elle-même. Ces moyens de tension sont habituellement constitués par un ressort.A roller shutter is constituted by an apron which comes to wrap around a drum, driven in rotation by means of a crank or a strap. In the particular case of a roller shutter operated by a strap, the latter is moved back and forth between two extreme positions which correspond one to the high position, the other to the low position of the apron. The free end of the strap is preferably fixed on a reel, which has tensioning means, allowing the strap to be wound on itself. These tensioning means are usually constituted by a spring.

Le problème posé par la mise sous tension du ressort a été résolu de différentes manières. Il existe un premier type d'enrouleur de volet roulant livré avec le ressort de tension non tendu et la mise sous tension de celui-ci s'effectue sur le lieu même du montage. A cet effet, le tablier du volet roulant étant placé en position basse, le poseur met l'enrouleur sous tension en faisant effectuer au tambour de celui-ci plusieurs rotations et, ensuite, il vient fixer la sangle sur le tambour de l'enrouleur en évitant de lâcher celui-ci. Cette opération présente des dangers réels pour les mains du poseur. Ce type d'enrouleur est proposé avec ou sans boîtier de protection. Toutefois, le modèle avec boîtier de protection, bien qu'il améliore sensiblement l'esthétique de l'enrouleur, présente certains inconvénients. En particulier, en cas de rupture accidentelle de la sangle ultérieurement à la pose, le démontage et le remontage de l'enrouleur sont délicats et il est souvent préférable de changer l'enrouleur.The problem of tensioning the spring has been solved in different ways. There is a first type of roller shutter reel delivered with the tension spring not tensioned and the tensioning of this takes place at the same place of assembly. To this end, the roller shutter deck being placed in the low position, the installer puts the reel under tension by making the latter's drum perform several rotations and, then, he comes to fix the strap on the reel drum avoiding dropping it. This operation presents real dangers for the hands of the installer. This type of reel is available with or without a protective box. However, the model with protective casing, although it appreciably improves the aesthetics of the reel, has certain drawbacks. In particular, in the event of an accidental rupture of the strap after installation, disassembly and reassembly of the reel are delicate and it is often preferable to change the reel.

Il existe un autre type d'enrouleur livré avec le ressort tendu et protégé par un boîtier de protection. Cet enrouleur présente une languette solidaire du tambour mis sous tension, et .maintenue en dehors du boîtier au moyen d'un rivet de retenue. Après avoir fixé la sangle sur la languette, on peut retirer le rivet de retenue, ce qui provoque la détente du ressort et l'enroulement de la sangle sur elle-même. Mais ensuite, il faut procéder à la mise en place et à la fixation du pince-sangle dans l'ouverture du boîtier en utilisant par exemple un marteau ou des pinces. Cette opération peut se révéler dangereuse pour les mains du poseur. De plus, vu le grand nombre de pièces, ce type d'enrouleur présente l'inconvénient de ne pas être facilement démontable et oblige à le remplacer en cas de rupture accidentelle de la sangle.There is another type of reel delivered with the spring tensioned and protected by a protective case. This reel has a tongue secured to the drum energized, and. Maintained outside the housing by means of a retaining rivet. After fixing the strap on the tongue, you can remove the retaining rivet, which causes the spring to relax and the strap to wind up on itself. But then, it is necessary to proceed to the installation and the fixing of the strap clamp in the opening of the case by using for example a hammer or pliers. This operation can be dangerous for the hands of the installer. In addition, given the large number of parts, this type of reel has the disadvantage of not being easily removable and requires replacement in the event of accidental breakage of the strap.

Un autre inconvénient des enrouleurs existants vient de la nature de la fixation de la sangle sur le tambour de l'enrouleur. Celle-ci étant généralement réalisée au moyen d'une vis ou d'un rivet, il faut préalablement au montage, poinçonner la sangle pour réaliser le trou nécessaire au passage de la vis ou du rivet.Another disadvantage of existing reels comes from the nature of the fixing of the strap on the drum of the reel. This is generally carried out by means of a screw or a rivet, before mounting, punch the strap to make the hole necessary for the passage of the screw or rivet.

Le but principal de la présente invention est de proposer un enrouleur livré avec un boîtier de protection qui permet la mise sous tension des moyens élastiques pouvant entraîner le tambour, depuis l'extérieur du boîtier, la sangle étant déjà montée sur l'enrouleur, et le boîtier étant fermé.The main object of the present invention is to provide a reel delivered with a protective box which allows the tensioning of the elastic means which can drive the drum, from the outside of the box, the strap being already mounted on the reel, and the housing being closed.

Un autre but de la présente invention est de proposer un enrouleur tel que la mise sous tension des moyens élastiques pouvant entraîner le tambour, ne présente pas de danger pour les mains du poseur.Another object of the present invention is to provide a reel such that the tensioning of the elastic means which can drive the drum, does not present a danger to the hands of the installer.

Un autre but de la présente invention est de proposer un enrouleur réutilisable en cas de rupture accidentelle de la sangle.Another object of the present invention is to provide a reusable reel in the event of accidental rupture of the strap.

Un autre but de la présente invention est de proposer un enrouleur dont la pose est simple, le nombre de pièces réduit, et qui permet l'intervention d'un poseur non-expérimenté en cas d'incident.Another object of the present invention is to provide a reel whose installation is simple, the number of parts reduced, and which allows the intervention of a non-experienced installer in the event of an incident.

Un autre but de la présente invention est de proposer un enrouleur dont la fixation de la sangle sur le tambour est réalisée par des moyens qui pincent l'extrémité de la sangle.Another object of the present invention is to provide a reel, the fixing of the strap on the drum is carried out by means which pinch the end of the strap.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre, qui n'est donné qu'à titre indicatif et qui n'a pas pour but de la limiter.Other objects and advantages of the present invention will emerge during the description which follows, which is given for information only and which is not intended to limit it.

L'enrouleur notamment destiné à recevoir une sangle de manoeuvre d'un volet roulant, comprenant en particulier un boîtier constituant un carter fermé, une ouverture pour la sortie de l'a sangle, un tambour d'enroulement de la sangle sur elle-même, des moyens élastiques susceptibles d'être mis sous tension pour entraîner le tambour et autoriser le va-et-vient de la sangle de l'intérieur du boîtier, est caractérisé par le fait qu'il présente des moyens accessibles de l'extérieur du carter fermé pour réaliser ladite mise sous tension.The retractor in particular intended to receive an operating strap for a roller shutter, comprising in particular a housing constituting a closed casing, an opening for the exit of the strap, a drum for winding the strap on itself , elastic means capable of being tensioned to drive the drum and allow the belt to move back and forth from the inside of the housing, is characterized in that it has means accessible from outside the casing closed to carry out said tensioning.

L'invention sera mieux comprise si l'on se réfère à la description ci-dessous ainsi qu'aux dessins en annexe qui en font partie intégrante.

The invention will be better understood if reference is made to the description below and to the accompanying drawings which form an integral part thereof.
  • Figure 1 shows a preferred embodiment of a reel according to the invention.
  • Figure 2 shows the drum and the cover of the roller according to the embodiment of Figure 1.
  • FIG. 3 illustrates, in cross section at the axis, the embodiment of FIG. 1.
  • FIG. 4 illustrates the section 40-40 of the axis according to the embodiment of FIG. 3.

Les figures 1 et 2 représentent un mode préférentiel de réalisation d'un enrouleur selon l'invention. Cet enrouleur, notamment destiné à recevoir une sangle de manoeuvre d'un volet roulant, comprend un bottier 1 constituant un carter fermé, qui présente une ouverture 2 pour la sortie de la sangle 3 et un tambour d'enroulement 4 de la sangle sur elle-même. Cet enrouleur comprend également des moyens élastiques susceptibles d'être mis sous tension pour entraîner le tambour 4 et autoriser le va-et-vient de la sangle 3 à l'intérieur du boîtier 1.Figures 1 and 2 show a preferred embodiment of a reel according to the invention. This reel, in particular intended to receive a maneuvering strap for a roller shutter, comprises a case 1 constituting a closed casing, which has an opening 2 for the exit of the strap 3 and a winding drum 4 of the strap on it -even. This reel also includes elastic means capable of being tensioned to drive the drum 4 and allow the back and forth of the strap 3 to go inside the housing 1.

Le tambour 4 étant placé à l'intérieur du boîtier 1, l'enrouleur selon l'invention, présente des moyens accessibles de l'extérieur du boîtier fermé 1 pour réaliser la mise sous tension des moyens élastiques entraînant le tambour 4. La mise sous tension des moyens élastiques est effectuée alors que la sangle 3 est déjà montée sur le tambour 4 et que le boîtier 1 est fermé.The drum 4 being placed inside the housing 1, the reel according to the invention has means accessible from the outside of the closed housing 1 for carrying out the tensioning of the elastic means driving the drum 4. The placing under tension of the elastic means is carried out while the strap 3 is already mounted on the drum 4 and the housing 1 is closed.

Pour la mise en place du tambour 4 dans le boîtier 1, celui-ci présente une ouverture 5 masquée par un couvercle amovible 6 et, les moyens accessibles de l'extérieur du boîtier 1 pour la mise sous tension des moyens élastiques seront avantageusement constitués par le couvercle 6.For the establishment of the drum 4 in the housing 1, the latter has an opening 5 masked by a removable cover 6 and, the means accessible from outside the housing 1 for tensioning the elastic means will advantageously consist of cover 6.

Dans le mode de réalisation illustré à la figure 2, le tambour d'enroulement 4 possède un axe de rotation 7, et les moyens élastiques susceptibles d'être mis sous tension sont entraînés par cet axe 7 du tambour d'enroulement 4. Dans l'enrouleur selon l'invention, le couvercle 6 est solidaire de cet axe 7. Par conséquent, la rotation du couvercle 6 s'accompagne de la rotation de l'axe 7 du tambour qui provoque la mise sous tension des moyens élastiques.In the embodiment illustrated in Figure 2, the winding drum 4 has an axis of rotation 7, and the elastic means capable of being tensioned are driven by this axis 7 of the winding drum 4. In the 'reel according to the invention, the cover 6 is integral with this axis 7. Consequently, the rotation of the cover 6 is accompanied by the rotation of the axis 7 of the drum which causes the elastic means to be tensioned.

Plus précisément, le tambour 4 est constitué par deux flasques 8 et 9 parallèles, perpendiculaires à l'axe de rotation 7, et reliés par la surface cylindrique d'enroulement 10 de la sangle, dont les génératrices sont parallèles à l'axe de rotation 7.More specifically, the drum 4 is constituted by two parallel flanges 8 and 9, perpendicular to the axis of rotation 7, and connected by the cylindrical winding surface 10 of the strap, whose generatrices are parallel to the axis of rotation 7.

En ce qui concerne le boîtier 1, sa forme est définie à partir de l'encombrement du tambour 4. Ce boîtier est essentiellement constitué par deux parois 11 et 12 perpendiculaires à l'axe de rotation 7 du tambour et, reliées par une paroi latérale 13 dont les génératrices sont de préférence parallèles à l'axe 7. Le couvercle 6 est situé de préférence sur l'une des parois perpendiculaire à l'axe 7, par exemple sur la paroi 11. Il sera avantageusement constitué par un panneau. Par ailleurs, l'ouverture 2 pour la sortie de la sangle 3 est réalisée dans la surface latérale 13 du bottier 1.Regarding the housing 1, its shape is defined from the size of the drum 4. This housing is essentially constituted by two walls 11 and 12 perpendicular to the axis of rotation 7 of the drum and, connected by a side wall 13 including generators are preferably parallel to the axis 7. The cover 6 is preferably located on one of the walls perpendicular to the axis 7, for example on the wall 11. It will advantageously consist of a panel. Furthermore, the opening 2 for the exit of the strap 3 is made in the lateral surface 13 of the boot 1.

En ce qui concerne les moyens élastiques susceptibles d'être ' mis sous tension, ils sont avantageusement constitués par un ressort en spirale 14 dont l'une des extrémités 15 est solidaire du tambour 4, et dont l'autre extrémité 16 peut être entraînée par l'axe de rotation 7 du tambour. Par conséquent, si le tambour 4 est maintenu dans une position déterminée, la rotation du couvercle 6 engendre une tension dans le ressort 14 qui tend à s'opposer au sens de rotation du couvercle 6. Le ressort 14 sera de préférence placé dans le tambour 4 autour de l'axe de rotation 7.As regards the elastic means capable of being 'tensioned, they are advantageously constituted by a spiral spring 14, one of the ends 15 of which is integral with the drum 4, and the other end of which 16 can be driven by the axis of rotation 7 of the drum. Consequently, if the drum 4 is kept in a determined position, the rotation of the cover 6 generates a tension in the spring 14 which tends to oppose the direction of rotation of the cover 6. The spring 14 will preferably be placed in the drum 4 around the axis of rotation 7.

Le couvercle 6 possède sur sa face extérieure 17 une ou plusieurs encoches ou aspérités qui permettent de l'entraîner en rotation autour de l'axe 7. Sur la figure 1, est illustrée une encoche 18 réalisée au centre du couvercle 6. Etant donné que l'ouverture 5 est de préférence circulaire et de dimensions suffisantes pour autoriser l'engagement du tambour 4 dans le boîtier 1, le couvercle 6 a une forme circulaire dont le diamètre est supérieur au diamètre extérieur du tambour 4.The cover 6 has on its outer face 17 one or more notches or asperities which make it possible to drive it in rotation about the axis 7. In FIG. 1, a notch 18 illustrated in the center of the cover 6 is illustrated. the opening 5 is preferably circular and of sufficient size to allow the engagement of the drum 4 in the housing 1, the cover 6 has a circular shape whose diameter is greater than the outside diameter of the drum 4.

Pour la mise sous tension d'un enrouleur selon l'invention, on commence par fixer la sangle 3 sur le tambour 4, ensuite, on met en place le couvercle 6 sur l'ouverture 5. Pour procéder à l'opération de mise sous tension du ressort 14, l'opérateur fait effectuer au couvercle 6 le nombre de tours souhaité en maintenant le tambour 4 fixe au moyen de la sangle 3. Quand l'opération est terminée, il faut immobiliser en rotation le couvercle 6 par rapport au boîtier 1. A cet effet, le couvercle 6 présente des moyens qui permettent de l'immobiliser par rapport au boîtier 1; par exemple, la face interne 19 du couvercle présente au moins un ergot 20 qui vient s'engager dans une encoche 21 pratiquée dans le boîtier 1.For the tensioning of a reel according to the invention, one starts by fixing the strap 3 on the drum 4, then, one places the cover 6 on the opening 5. To proceed with the setting operation tension of the spring 14, the operator causes the cover 6 to perform the desired number of turns while keeping the drum 4 fixed by means of the strap 3. When the operation is complete, the cover 6 must be immobilized in rotation relative to the housing 1. To this end, the cover 6 has means which make it possible to immobilize it relative to the housing 1; for example, the internal face 19 of the cover has at least one lug 20 which engages in a notch 21 formed in the housing 1.

Selon le mode préférentiel de réalisation illustré aus figures 1 et 2, le couvercle 6 présente sur sa face intérieure 19 deux ergots 20, diamétralement opposés, et situés à sa périphérie. De son côté, le boîtier 1 présente à la périphérie de l'ouverture circulaire 5 un épaulement également de forme circulaire 22 sur lequel est appliqué le couvercle 6 lorsque celui-ci est mis en place sur le boîtier.According to the preferred embodiment illustrated in Figures 1 and 2, the cover 6 has on its inner face 19 two lugs 20, diametrically opposite, and located at its periphery. For its part, the housing 1 has at the periphery of the circular opening 5 a shoulder also of circular shape 22 on which the cover 6 is applied when the latter is placed on the housing.

Le boîtier 1 présente sur le bord de l'ouverture 5, au niveau de l'épaulement 22, deux échancrures 21, diamétralement opposées, dans lesquelles viennent s'immobiliser les ergots 20 du couvercle. Par la présence de ces deux échancrures 21, le couvercle 6 peut s'immobiliser sur le boîtier en deux positions opposées.The housing 1 has on the edge of the opening 5, at the shoulder 22, two notches 21, diametrically opposite, in which come to rest the pins 20 of the cover. By the presence of these two notches 21, the cover 6 can be immobilized on the housing in two opposite positions.

L'immobilisation axiale du couvercle 6 et du tambour 4 sur le boîtier 1, sera avantageusement réalisée au niveau de l'axe 7 comme il est illustré sur la figure 3. A cet effet, la longueur de l'axe 7 du tambour est telle que son extrémité 23, opposée au couvercle 6, est située sensiblement dans le plan de la paroi 12 et débouche à l'extérieur du boîtier par un trou 24 pratiqué dans la paroi 12. L'extrémité 23 de l'axe présente un troù taraudé 25 dans lequel vient s'engager une vis 26 qui immobilise axialement le couvercle 6 sur le boîtier 1.The axial immobilization of the cover 6 and the drum 4 on the housing 1 will advantageously be carried out at the level of the axis 7 as illustrated in FIG. 3. For this purpose, the length of the axis 7 of the drum is such that its end 23, opposite the cover 6, is located substantially in the plane of the wall 12 and opens out of the housing through a hole 24 made in the wall 12. The end 23 of the axis has a threaded hole 25 in which a screw 26 is engaged which axially immobilizes the cover 6 on the housing 1.

La figure 1 illustre en section suivant 40-40 la liaison de l'extrémité 16 du ressort avec l'axe 7 du tambour. L'axe de rotation 7 est constitué par un axe de section carrée 27, sur lequel est placée une bague 28, de section extérieure circulaire, mais qui présente dans sa zone centrale une dent 29 qui peut s'engager dans l'ouverture 30 pratiquée dans l'extrémité 16 du ressort 14. La dent 29 est telle que seule la rotation dans un seul sens de l'axe entraîne l'extrémité 16 du ressort. Le sens de rotation qui provoque la mise sous tension du ressort est illustré à la figure 1 par la flèche 31 dirigée dans le sens opposé aux aiguilles d'une horloge.Figure 1 illustrates in section 40-40 the connection of the end 16 of the spring with the axis 7 of the drum. The axis of rotation 7 is constituted by an axis of square section 27, on which is placed a ring 28, of circular outer section, but which has in its central zone a tooth 29 which can engage in the opening 30 made in the end 16 of the spring 14. The tooth 29 is such that only rotation in one direction of the axis drives the end 16 of the spring. The direction of rotation which causes the spring to be tensioned is illustrated in FIG. 1 by the arrow 31 directed in the opposite direction to the hands of a clock.

La fixation de l'extrémité 15 du ressort sur le tambour est d'un type connu. Par exemple, une languette 32, située à partir de la surface d'enroulement 10, intérieurement au tambour 4, vient s'engager dans une ouverture 33 pratiquée dans l'extrémité 15 du ressort. Cette languette 32 sera orientée convenablement pour obtenir la mise sous tension du ressort 14 lorsque le couvercle 6 est déplacé dans le sens de la flèche 31.The attachment of the end 15 of the spring to the drum is of a known type. For example, a tongue 32, located from the winding surface 10, inside the drum 4, engages in an opening 33 made in the end 15 of the spring. This tongue 32 will be properly oriented to obtain tension on the spring 14 when the cover 6 is moved in the direction of the arrow 31.

La surface d'enroulement 10 du tambour présente une zone en dépression 34 dans laquelle est placé un plat basculant 35 qui pince l'extrémité de la sangle 3. Le plat 35 disposé parallèlement à l'axe 7 possède deux ergots 36 qui sont introduits dans deux trous 37 pratiqués dans les flasques 8 et 9 du tambour. L'extrémité de la sangle 3 est introduite dans la zone en dépression 34 sous le plat basculant 35 et ensuite elle est repliée autour du plat basculant 35 du côté de son extrémité. Le plat 35 agit ainsi comme une pince auto-serrante qui maintient l'extrémité de la sangle sur la surface d'enroulement 10.The winding surface 10 of the drum has a depression area 34 in which is placed a tilting plate 35 which clamps the end of the strap 3. The plate 35 disposed parallel to the axis 7 has two lugs 36 which are introduced into two holes 37 made in the flanges 8 and 9 of the drum. The end of the strap 3 is introduced into the vacuum zone 34 under the tilting plate 35 and then it is folded around the tilting plate 35 on the side of its end. The plate 35 thus acts as a self-clamping clamp which holds the end of the strap on the winding surface 10.

Le boîtier de l'enrouleur selon l'invention, présentera avantageusement dans l'ouverture 2 un pince-sangle 38 connu de l'Homme de Métier qui sert à immobiliser la sangle 3 par rapport au bottier. En outre, le boîtier 1 possède à sa partie supérieure et à sa partie inférieure deux pattes de fixation 39 qui sont utilisées pour fixer l'enrouleur sur son support.The housing of the retractor according to the invention will advantageously have in the opening 2 a strap clamp 38 known to those skilled in the art which serves to immobilize the strap 3 relative to the shoemaker. In addition, the housing 1 has at its upper part and at its lower part two fixing lugs 39 which are used to fix the reel on its support.

Pour effectuer la pose d'un enrouleur selon l'invention, on procède de la manière suivante : on vient fixer le boîtier 1 sur le support à l'aide des pattes 39, on place le volet en position basse, on retire le tambour 4 du boîtier, on introduit la sangle 3 dans l'ouverture 2 et ensuite on fixe l'extrémité de la sangle 3 sur le tambour 4 au moyen de la pince 35. Ensuite, on met en place le couvercle 6 sur le boîtier, on vient immobiliser axialement le couvercle 6 à l'aide de la vis 26 en laissant un jeu axial suffisant pour permettre la rotation du couvercle 6, ensuite, on entraîne en rotation le couvercle 6 au moyen de l'encoche 18 en maintenant fixe la sangle 3. La tension maximale du ressort est obtenue pour une dizaine de tours mais on peut régler cette tension à une valeur différente suivant les dimensions du volet roulant. Ensuite, on immobilise le couvercle 6 en rotation en introduisant les ergots 20 dans les encoches 21, et on vient serrer la vis 26 sur l'axe 7 pour immobiliser le couvercle et le tambour dans le boîtier.To install a reel according to the invention, the procedure is as follows: the housing 1 is fixed to the support using the lugs 39, the flap is placed in the low position, the drum 4 is removed of the housing, we introduce the strap 3 into the opening 2 and then we fix the end of the strap 3 on the drum 4 by means of the clamp 35. Then, we put the cover 6 on the housing, we come axially immobilize the cover 6 using the screw 26, leaving sufficient axial clearance to allow the cover 6 to rotate, then the cover 6 is rotated by means of the notch 18 while keeping the strap 3 fixed. The maximum spring tension is obtained for about ten turns, but this tension can be adjusted to a different value depending on the dimensions of the roller shutter. Then, the cover 6 is immobilized in rotation by introducing the lugs 20 into the notches 21, and the screw 26 is tightened on the axis 7 to immobilize the cover and the drum in the housing.

Le mode de réalisation qui vient d'être décrit n'est donné qu'à titre indicatif, et d'autres mises en oeuvre de la présente invention, à la portée de l'Homme de l'Art, pourraient être adoptées sans pour autant sortir du cadre de celle-ci.The embodiment which has just been described is given for information only, and other implementations of the present invention, within the reach of ordinary skill in the art, could be adopted without however get out of it.
