Description

L'invention concerne le domaine technique des volets roulants destinés à équiper tout type d'ouverture susceptible de recevoir une fenêtre ou autre.The invention relates to the technical field of roller shutters intended to equip any type of opening capable of receiving a window or other.

D'une manière parfaitement connue par un homme de métier, un volet roulant comprend, pour l'essentiel, un caisson dans lequel est enroulé le tablier généralement exécuté à partir de lames articulées entre elles. Le caisson est positionné en combinaison avec des coulisses pour le guidage des lames, au fur et à mesure de leur enroulement ou déroulement, d'une manière manuelle ou d'une manière automatique.In a manner that is well known to a person skilled in the art, a roller shutter essentially comprises a box in which the apron is generally wound from blades articulated between them. The box is positioned in combination with slides for guiding the blades, as and when winding or unwinding, in a manual manner or automatically.

Le mécanisme d'enroulement est monté à l'intérieur du caisson de forme générale parallélépipédique. Ce mécanisme comprend un axe sur lequel sont accrochées les lames. L'axe est monté à chacune de ses extrémités avec capacité de rotation sur des joues latérales conformées pour être fixées sur les faces transversales ouvertes du caisson. L'axe peut présenter tout agencement pour être entraîné manuellement au moyen d'un treuil ou d'une sangle par exemple, ou automatiquement, par un moteur électrique par exemple.The winding mechanism is mounted inside the casing of generally parallelepipedal shape. This mechanism comprises an axis on which the blades are hung. The axis is mounted at each of its ends with rotational capacity on side cheeks shaped to be fixed on the open transverse faces of the box. The axis may have any arrangement to be driven manually by means of a winch or a strap for example, or automatically by an electric motor for example.

Compte tenu de ces dispositions, il apparaît que l'axe d'enroulement est totalement indépendant des joues latérales lesquelles nécessitent d'être supportées par le caisson pour justement permettre le montage de l'axe. Ce caisson est donc nécessaire pour porter l'ensemble du mécanisme. On observe également que le montage tournant de l'axe s'effectue généralement au moyen de roulements rapportés.Given these provisions, it appears that the winding axis is completely independent of the side cheeks which need to be supported by the box to precisely allow the mounting of the axis. This box is necessary to carry the entire mechanism. It is also observed that the rotating assembly of the axis is generally effected by means of reported bearings.

Il en résulte des difficultés de montage et de réglage avec le risque de perdre des pièces. On peut noter également que l'ensemble du caisson et des joues est nécessaire pour soutenir l'ensemble du volet étant donné que l'axe normalement a seulement pour fonction de permettre l'accrochage des lames.This results in difficulties of assembly and adjustment with the risk of losing parts. It can also be noted that the entire box and cheeks is necessary to support the entire shutter since the axis normally only serves to allow the attachment of the blades.

L'invention s'est fixée pour but de remédier à ces inconvénients d'une manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these disadvantages in a simple, safe, effective and rational manner.

Le problème que se propose de résoudre l'invention est de pouvoir standardiser la fabrication du volet et de faciliter sa mise en place avec un fonctionnement parfait.The problem to be solved by the invention is to standardize the manufacture of the shutter and facilitate its implementation with perfect operation.

Pour résoudre un tel problème, il a été conçu et mis au point un tambour d'enroulement pour volet roulant à lames articulées. Ce tambour est constitué d'un ensemble unitaire comprenant un axe principal rendu solidaire, à chaque extrémité, avec capacité de rotation, de deux joues latérales de fixation, ledit axe présentant des agencements pour l'accrochage des lames et des moyens d'accouplement à un organe d'entraînement en rotation.To solve such a problem, it has been designed and developed a winding drum for rolling shutters with articulated blades. This drum consists of a unitary assembly comprising a main axis made integral, at each end, with rotational capacity, with two lateral attachment cheeks, said axis having arrangements for fastening the blades and coupling means to a rotating drive member.

Ces dispositions permettent avantageusement de supprimer le caisson.These provisions advantageously make it possible to remove the box.

Pour résoudre le problème posé d'assurer le montage tournant de l'axe principal, les extrémités de l'axe sont fixées dans des roulements creux rendus solidaires des joues.To solve the problem of ensuring the rotational mounting of the main axis, the ends of the axis are fixed in hollow bearings made integral with the cheeks.

Pour résoudre le problème posé de permettre à l'axe principal, non seulement d'accrocher les lames, mais d'assurer également leur soutien en faisant office d'axe porteur, ce dernier est constitué par un arbre creux présentant intérieurement des nervures de rigidité.To solve the problem posed to allow the main axis, not only to hang the blades, but also to ensure their support as a carrier axis, the latter is constituted by a hollow shaft internally having stiffness ribs .

Les nervures sont disposées, d'une manière radiale et convergente à partir de la périphérie interne de l'arbre.The ribs are radially and convergently disposed from the inner periphery of the shaft.

Pour résoudre le problème posé de permettre l'accrochage des lames, notamment de la lame située à l'extrémité du tablier constituant le volet ou autre, les agencements d'accrochage des lames sont constitués par au moins une forme en crochet formée en débordement des génératrices de l'arbre, en combinaison avec des éléments de blocage fixés sur ledit arbre.To solve the problem posed to allow the attachment of the blades, in particular the blade located at the end of the deck constituting the flap or the like, the fastening arrangements of the blades are constituted by at least one hook shape formed in overflow of generators of the shaft, in combination with locking elements fixed on said shaft.

Les éléments de blocage sont constitués par différents tronçons répartis sur la totalité de la longueur de l'arbre.The locking elements are constituted by different sections distributed over the entire length of the shaft.

Pour résoudre le problème posé de constituer un ensemble monobloc et unitaire, le corps des roulements est fixé sur un épaulement formé à chaque extrémité de l'arbre afin de ne pas déborder du diamètre de ce dernier et être en alignement avec ses génératrices.To solve the problem of forming a unitary and unitary assembly, the body of the bearings is fixed on a shoulder formed at each end of the shaft so as not to exceed the diameter of the latter and be in alignment with its generators.

Pour résoudre le problème posé de l'entraînement en rotation de l'axe principal, les moyens d'accouplement à un organe d'entraînement sont constitués par un moteur tubulaire engagé dans l'alésage de l'arbre.To solve the problem posed by the rotational drive of the main axis, the means for coupling to a drive member consist of a tubular motor engaged in the bore of the shaft.

Selon une autre caractéristique, les joues solidaires de l'axe d'enroulement présentent des tenons aptes à être engagés dans des coulisses pour le guidage des lames au fur et à mesure de l'enroulement ou du déroulement du volet.According to another characteristic, the integral cheeks of the winding axis have tenons adapted to be engaged in the slides for guiding the blades as the winding or unwinding of the flap.

L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels :

  • la figure 1 est une vue en perspective du tambour d'enroulement pour volet roulant selon l'invention ;
  • la figure 2 est une vue partielle en perspective du tambour montrant sa mise en place par rapport aux coulisses au niveau de l'ouverture à équiper ;
  • la figure 3 est une vue partielle en coupe longitudinale du tambour ;
  • la figure 4 est une vue en coupe transversale de l'axe principal montrant l'accrochage des lames.
The invention is described below in more detail with reference to the figures of the accompanying drawings, in which:
  • Figure 1 is a perspective view of the winding drum for roller shutter according to the invention;
  • Figure 2 is a partial perspective view of the drum showing its implementation relative to the slides at the opening to be equipped;
  • Figure 3 is a partial view in longitudinal section of the drum;
  • Figure 4 is a cross-sectional view of the main axis showing the attachment of the blades.

Le tablier du volet roulant est constitué, d'une manière parfaitement connue, d'une pluralité de lames articulées entre elles (L). Le profil transversal des lames pour permettre leur accouplement d'une manière articulée, peut être conforme à l'un des modes d'exécution parfaitement connus par l'homme du métier. De même, chaque lame peut être en tout matériau (aluminium, PVC, ...).The apron of the roller shutter is constituted, in a perfectly known manner, a plurality of blades articulated together (L). The transverse profile of the blades to allow their coupling in an articulated manner, may be in accordance with one of the embodiments well known to those skilled in the art. Similarly, each blade can be of any material (aluminum, PVC, ...).

Selon une caractéristique à la base de l'invention, l'enroulement des lames (L), généralement par rapport à des coulisses (C) fixées de part et d'autre de l'ouverture à équiper, s'effectue au moyen d'un ensemble compact unitaire désigné par (E).According to a characteristic underlying the invention, the winding of the blades (L), generally with respect to slides (C) fixed on either side of the opening to be equipped, is effected by means of a unitary compact unit designated by (E).

Cet ensemble comprend un axe principal (1) rendu solidaire à chaque extrémité, avec capacité de rotation de deux joues latérales (2) et (3). Les extrémités de l'axe (1) sont rendues solidaires d'organes de roulement (4) fixés au niveau de chacune des joues latérales (2) et (3). Les roulements (4) sont du type de ceux couramment utilisés dans le commerce. Par exemple, ces organes de roulement (4) sont du type de ceux dont le principe est illustré figure 3.This assembly comprises a main axis (1) secured to each end, with rotational capacity of two side cheeks (2) and (3). The ends of the shaft (1) are made integral with rolling members (4) fixed at each of the side flanges (2) and (3). Bearings (4) are of the type commonly used in commerce. For example, these rolling members (4) are of the type of those whose principle is illustrated in FIG.

Le corps (4a) des roulements est fixé sur un épaulement (1a) formé à chaque extrémité de l'arbre. Après emmanchement du corps (4a) de l'organe de roulement (4) sur l'épaulement (1a), le diamètre externe dudit corps (4a) ne déborde pas du diamètre externe de l'axe (1) qui se trouve en alignement avec les génératrices de ce dernier.The body (4a) of the bearings is fixed on a shoulder (1a) formed at each end of the shaft. After fitting the body (4a) of the rolling member (4) on the shoulder (1a), the outer diameter of said body (4a) does not exceed the outside diameter of the axis (1) which is in alignment with the generators of the latter.

Selon une autre caractéristique, l'axe principal présente des agencements pour l'accrochage des lames (L) et est conformé en section pour supporter lesdites lames. Avantageusement, cet axe est constitué par un arbre creux présentant intérieurement des nervures de rigidité (1b). Comme le montre la figure 4, les nervures (1b) sont disposées d'une manière radiale et convergente à partir de la périphérie interne de l'arbre (1).According to another feature, the main axis has arrangements for the attachment of the blades (L) and is shaped in section to support said blades. Advantageously, this axis is constituted by a hollow shaft internally having stiffness ribs (1b). As shown in Figure 4, the ribs (1b) are arranged radially and convergent from the inner periphery of the shaft (1).

Sans pour cela sortir du cadre de l'invention, d'autres agencements, sous forme de nervures ou autres, peuvent être formés à l'intérieur de l'alésage de l'arbre (1) pour augmenter sa rigidité afin d'éviter tout phénomène de flexion. Par exemple, la section transversale peut être du type alvéolaire.Without departing from the scope of the invention, other arrangements, in the form of ribs or the like, can be formed inside the bore of the shaft (1) to increase its rigidity to avoid any bending phenomenon. For example, the cross section may be of the alveolar type.

Pour assurer l'accouplement de la lame d'extrémité du tablier du volet, l'arbre (1) présente au moins une forme en crochet (1c) formée en débordement des génératrices dudit arbre et d'une manière parallèle à ces dernières. Cette forme en crochet (1c) s'étend sur la quasi-totalité de la longueur de l'arbre correspondant à la longueur de la lame d'extrémité considérée du volet. Bien évidemment, cette forme en crochet (1c) coopère avec une forme en crochet complémentaire que présente la lame d'extrémité correspondante.To ensure the coupling of the end plate of the flap of the flap, the shaft (1) has at least one hook shape (1c) formed in overflow of the generatrices of said shaft and in a manner parallel thereto. This hook shape (1c) extends over almost all of the length of the shaft corresponding to the length of the end blade considered shutter. Of course, this hook shape (1c) cooperates with a complementary hook shape that has the corresponding end plate.

Pour assurer le maintien des différentes lames, des éléments de blocage (5) sont fixés au niveau de la forme en crochet (1c). Par exemple, ces éléments de blocage (5) présentent une partie d'appui et de fixation (5a) avec l'arbre (1) et une partie (5b) de recouvrement de l'extrémité d'accrochage de la lame coopérant avec la forme en crochet (1c). Avantageusement, différents éléments de blocage sont répartis sur la totalité de la longueur de l'arbre. Par exemple, ces éléments de blocage (5) sont fixés par des vis (6) engagées entre deux nervures consécutives (1b).To ensure the maintenance of the different blades, locking elements (5) are fixed at the hook shape (1c). For example, these locking elements (5) have a bearing and fixing part (5a) with the shaft (1) and a portion (5b) for covering the fastening end of the blade cooperating with the hook shape (1c). Advantageously, different locking elements are distributed over the entire length of the shaft. For example, these locking elements (5) are fixed by screws (6) engaged between two consecutive ribs (1b).

La structure interne de l'arbre (1) permet l'engagement d'un moteur tubulaire pour l'entraînement en rotation dudit arbre. Bien évidemment, l'arbre (1) peut présenter des agencements pour son entraînement manuel soit au moyen d'un système de treuil, soit au moyen d'un système de sangles.The internal structure of the shaft (1) allows the engagement of a tubular motor for the rotational drive of said shaft. Of course, the shaft (1) may have arrangements for its manual drive either by means of a winch system or by means of a system of straps.

A noter que les joues (2) et (3), solidaires de l'arbre (1), présentent des tenons (7) aptes à être engagés dans les coulisses (C). De même, les joues peuvent être équipées d'organes de guidage pour les lames (L) pour faciliter leur enroulement et déroulement.Note that the cheeks (2) and (3), integral with the shaft (1), have tenons (7) capable of being engaged in the wings (C). Similarly, the cheeks may be equipped with guide members for the blades (L) to facilitate their winding and unwinding.

La fixation de l'ensemble compact d'enroulement selon l'invention, peut être effectuée soit en fixant les joues (2) et (3) par vissage, par clipage,

  • ... dans l'ouverture à équiper, soit en fixant ledit ensemble dans des caissons préformés au niveau de ladite ouverture.
The fixing of the compact winding assembly according to the invention can be carried out either by fixing the cheeks (2) and (3) by screwing, by clipping,
  • ... in the opening to be equipped, or by fixing said assembly in preformed boxes at said opening.

Les avantages ressortent bien de la description, en particulier on souligne et on rappelle :

  • la possibilité de supprimer le caisson ou toute autre liaison mécanique pour la fixation des joues ;
  • la rigidité de l'axe d'enroulement qui permet l'accrochage et le support des lames en faisant office de poutre ;
  • la rigidité de l'axe évitant tout phénomène de flexion ;
  • la possibilité d'intégrer dans l'alésage de l'axe, un moteur d'entraînement ;
  • la rationalisation et la standardisation de la fabrication de l'ensemble compact ;
  • la facilité et la rapidité de l'installation ;
  • la facilité d'enroulement des lames sur l'axe-poutre compte tenu de son diamètre supérieur à celui des axes seuls utilisés selon l'état de la technique.
The advantages stand out well from the description, in particular one underlines and recalls:
  • the possibility of removing the box or any other mechanical connection for fixing the cheeks;
  • the rigidity of the winding axis which allows the attachment and support of the blades as a beam;
  • the rigidity of the axis avoiding any bending phenomenon;
  • the possibility of integrating into the bore of the axis, a drive motor;
  • rationalization and standardization of the manufacturing of the compact assembly;
  • the ease and speed of installation;
  • the ease of winding of the blades on the axis-beam given its diameter greater than that of the only axes used according to the state of the art.
