Description

La présente invention est relative à un dispositif d'entraînement en rotation d'un arbre d'enroulement et de déroulement d'un tablier de volet roulant.The present invention relates to a device for driving in rotation a winding shaft and unwinding a rolling shutter apron.

Le document DE 198 27 126 A1 décrit un dispositif conforme au préambule de la revendication 1.The document DE 198 27 126 A1 describes a device according to the preamble of claim 1.

Plus particulièrement, le dispositif d'entraînement comprend une poulie comprenant elle-même :

  • une jante et deux flasques qui encadrent ladite jante, la poulie étant destinée à entraîner l'arbre du volet roulant, et
  • un lien de manoeuvre souple qui est enroulé autour de la jante de la poulie et fixé à ladite poulie par un dispositif d'accrochage.
More particularly, the driving device comprises a pulley comprising itself:
  • a rim and two flanges which frame said rim, the pulley being intended to drive the shaft of the shutter, and
  • a flexible operating link which is wrapped around the rim of the pulley and fixed to said pulley by an attachment device.

Ce type de dispositif d'entraînement permet à l'arbre d'être entraîné en rotation dans le sens de la montée du tablier, par traction manuelle sur le lien de manoeuvre qui a été au préalable enroulé sur la poulie. Dans le sens de la descente du tablier, l'arbre est entraîné dans le sens contraire de rotation en raison du propre poids du tablier.This type of drive device allows the shaft to be rotated in the direction of the rise of the apron, by manual traction on the operating link which has been previously wound on the pulley. In the direction of the descent of the deck, the shaft is driven in the opposite direction of rotation due to the own weight of the deck.

L'inconvénient majeur de ce dispositif d'entraînement réside particulièrement dans le fait que l'accrochage du lien de manoeuvre à la poulie est généralement réalisé par un ergot. Or, en cas de manoeuvre brutale et de l'inertie du dispositif, il peut se produire des décrochements intempestifs du lien de manoeuvre par rapport à la poulie, impliquant donc un démontage complet de l'installation pour effectuer un ré-accrochage dudit lien de manoeuvre, telle qu'une sangle.The major disadvantage of this drive device lies particularly in the fact that the attachment of the operating link to the pulley is generally achieved by a lug. However, in the event of a sudden maneuver and the inertia of the device, it may occur inadvertent detachment of the operating link with respect to the pulley, thus implying a complete disassembly of the installation to effect a re-latching of said link. maneuver, such as a strap.

Pour pallier ce risque, on a sécurisé l'accrochage du lien de manoeuvre au niveau de l'ergot à l'aide d'un collage ou d'un vissage du lien de manoeuvre sur la poulie. Néanmoins, ces techniques de sécurisation ne sont pas infaillibles et elles nécessitent des opérations supplémentaires, qui compliquent l'installation du dispositif.To mitigate this risk, it has secured the attachment of the operating link at the pin by means of a gluing or screwing of the operating link on the pulley. Nevertheless, these security techniques are not infallible and they require additional operations, which complicate the installation of the device.

La présente invention a notamment pour but de pallier ces inconvénients.The present invention is intended to overcome these disadvantages.

A cet effet, selon l'invention, un dispositif d'entraînement du genre en question est caractérisé en ce qu'il comporte, en outre, un organe de maintien, qui est solidaire de la poulie, ledit organe de maintien délimitant un passage dans lequel passe le lien de manoeuvre en retenant ledit lien de manoeuvre au voisinage de la jante, le lien de manoeuvre étant en permanence enroulé autour de la jante entre le dispositif d'accrochage et l'organe de maintien sur au moins un arc de cercle de longueur non nulle.For this purpose, according to the invention, a drive device of the kind in question is characterized in that it further comprises a holding member, which is integral with the pulley, said holding member delimiting a passage in which passes the link maneuver retaining said link of maneuvering in the vicinity of the rim, the operating link being permanently wound around the rim between the attachment device and the holding member on at least one non-zero length arc.

Grâce à ces dispositions et notamment à la présence de l'organe de maintien en amont (dans le sens du déroulement du lien par rapport à la poulie) du dispositif d'accrochage, l'accrochage du lien de manoeuvre sur la poulie est complètement sécurisé, cet organe de maintien faisant office de butée préalable lors du mouvement de déroulement dudit lien et évitant toute sollicitation mécanique du dispositif d'accrochage qui tendrait à en décrocher le lien de manoeuvre.Thanks to these provisions and in particular to the presence of the retaining member upstream (in the direction of unwinding of the link relative to the pulley) of the attachment device, the attachment of the operating link on the pulley is completely secure , this holding member acting as a prior stop during the unwinding movement of said link and avoiding any mechanical stress of the attachment device that tends to unhook the link maneuver.

Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :

  • l'organe de maintien est disposé de manière diamétralement opposée par rapport au dispositif d'accrochage autour de la jante,
  • l'organe de maintien est venu de fabrication avec la poulie,
  • l'organe de maintien constitue une pièce rapportée sur la poulie,
  • la poulie est une pièce symétrique par rapport à un plan passant à la fois par l'axe de rotation de la poulie et par le dispositif d'accrochage et l'organe de maintien,
  • l'organe de maintien est constitué d'une barrette transversale sensiblement parallèle à l'axe de rotation de la poulie.
In preferred embodiments of the invention, one or more of the following may also be used:
  • the holding member is disposed diametrically opposite to the hooking device around the rim,
  • the holding member came from manufacturing with the pulley,
  • the holding member constitutes an insert on the pulley,
  • the pulley is a symmetrical part with respect to a plane passing through both the axis of rotation of the pulley and by the attachment device and the holding member,
  • the holding member consists of a transverse bar substantially parallel to the axis of rotation of the pulley.

Selon un autre aspect de l'invention, celle-ci vise également un volet roulant comportant un caisson destiné à être encastré ou être monté en applique au sein d'une ouverture pratiquée dans un mur, ce caisson abritant, d'une part, un arbre d'enroulement et de déroulement d'un tablier du volet roulant, et, d'autre part, un dispositif d'entraînement tel que visé précédemment, la poulie de ce dispositif d'entraînement étant reliée à l'arbre d'entraînement pour commander l'enroulement et le déroulement du tablier autour de l'arbre d'entraînement.According to another aspect of the invention, it also relates to a shutter comprising a box intended to be recessed or to be mounted as a wall within an opening made in a wall, this box housing, on the one hand, a winding and unwinding shaft of a rolling shutter apron, and, on the other hand, a driving device as referred to above, the pulley of this driving device being connected to the drive shaft for control the winding and unwinding of the apron around the drive shaft.

D'autres caractéristiques et avantages de l'invention apparaîtront au cours de la description suivante d'une de ses formes de réalisation, donnée à titre d'exemple non limitatif, en regard des dessins joints.Other features and advantages of the invention will become apparent from the following description of one of its embodiments, given by way of non-limiting example, with reference to the accompanying drawings.

Sur les dessins :

  • la figure 1 est une vue en perspective schématique d'un volet roulant dont la manoeuvre d'enroulement et de déroulement du tablier est assurée par le dispositif d'entraînement objet de l'invention,
  • la figure 2 est une vue de côté du dispositif d'entraînement, et
  • la figure 3 est une vue en perspective de l'arbre d'enroulement et de déroulement du tablier du volet roulant, solidaire de la poulie représentée en figure 2.
On the drawings:
  • the figure 1 is a schematic perspective view of a roller shutter whose winding operation and unfolding of the deck is provided by the drive device object of the invention,
  • the figure 2 is a side view of the training device, and
  • the figure 3 is a perspective view of the winding and unwinding shaft of the shutter apron, integral with the pulley shown in FIG. figure 2 .

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

Sur la figure 1, on a représenté un volet roulant 1 qui comporte un caisson 2 destiné à être encastré ou être monté en applique au sein d'une ouverture pratiquée dans un mur, en vue de réaliser une baie pour fenêtre. Ce montage est connu en soi, il ne sera pas décrit plus en détail.On the figure 1 , there is shown a shutter 1 which comprises a box 2 intended to be recessed or to be mounted as a wall within an opening in a wall, to achieve a window bay. This assembly is known per se, it will not be described in more detail.

Ce caisson 2 est susceptible d'abriter, d'une part, un arbre 3 d'enroulement et de déroulement d'un tablier 4 du volet roulant, et, d'autre part, un dispositif d'entraînement 5 permettant d'assurer l'enroulement et le déroulement du tablier 4 autour de l'arbre 3.This box 2 is able to house, on the one hand, a shaft 3 for winding and unwinding an apron 4 of the roller shutter, and, on the other hand, a drive device 5 to ensure the winding and unfolding of the apron 4 around the shaft 3.

Ainsi, dans la partie interne du caisson 2 et à hauteur de ses extrémités latérales supérieures 6, 7 sont prévues des joues supports 8, 9. Chacune de ces joues intègre un palier 10, 11 dans lequel est monté libre en rotation, d'un côté sur la joue 8, l'extrémité libre 13 dudit arbre d'enroulement 3 et de l'autre côté, sur la joue 9, le dispositif d'entraînement 5 solidaire mécaniquement de l'autre extrémité 12 de l'arbre d'enroulement 3.Thus, in the inner part of the box 2 and at its upper lateral ends 6, 7 are provided support cheeks 8, 9. Each of these cheeks incorporates a bearing 10, 11 in which is mounted freely in rotation, a side on the cheek 8, the free end 13 of said winding shaft 3 and on the other side, on the cheek 9, the driving device 5 mechanically secured to the other end 12 of the winding shaft 3.

Les figures 2 et 3 illustrent en détail la constitution du dispositif d'entraînement 5. Ce dispositif d'entraînement 5 comprend une poulie 14 formée de deux flasques coaxiaux 15, 16 et encadrant une jante 17 (un seul 16 de ces flasques 15, 16 est visible sur la figure 2), un lien de manoeuvre 18 adapté à s'enrouler ou se dérouler en fonction du sens de rotation de la poulie 14 autour de l'axe de l'arbre 3 et de la jante 17, la poulie 14 étant montée solidaire en rotation de l'arbre d'enroulement 3 lié à une extrémité du tablier 4, le lien de manoeuvre 18 étant rendu solidaire de la poulie 14 par un dispositif d'accrochage 19.The Figures 2 and 3 illustrate in detail the constitution of the drive device 5. This drive device 5 comprises a pulley 14 formed of two coaxial flanges 15, 16 and surrounding a rim 17 (only one 16 of these flanges 15, 16 is visible on the figure 2 ), an operating link 18 adapted to wind or unwind according to the direction of rotation of the pulley 14 about the axis of the shaft 3 and the rim 17, the pulley 14 being mounted integral in rotation with the winding shaft 3 connected to one end of the deck 4, the operating link 18 being secured to the pulley 14 by an attachment device 19.

Dans l'exemple représenté en figure 2, le lien de manoeuvre 18 est constitué par une sangle, l'une des extrémités de cette sangle étant accrochée à la poulie 14 par un ergot formant le dispositif d'accrochage 19, et l'autre extrémité à un enrouleur de sangle 20, placé en position basse du volet roulant, ce dernier étant visible en figure 1.In the example shown in figure 2 , the operating link 18 is constituted by a strap, one end of this strap being attached to the pulley 14 by a lug forming the hooking device 19, and the other end to a strap winder 20, placed in the lower position of the roller shutter, the latter being visible in figure 1 .

Le dispositif d'entraînement comporte en outre un organe de maintien 21 positionné transversalement par rapport au sens d'enroulement et de déroulement du lien de manoeuvre 18 autour de la jante 17.The drive device further comprises a holding member 21 positioned transversely with respect to the direction of winding and unwinding of the operating link 18 around the rim 17.

Cet organe de maintien 21 délimite un passage 22 dans lequel passe le lien de manoeuvre 18 en retenant ledit lien de manoeuvre au voisinage de la jante 17, le lien de manoeuvre 18 étant en permanence enroulé autour de la jante 17 entre le dispositif d'accrochage 19 et l'organe de maintien 21 sur au moins un arc-de-cercle de longueur non nulle.This holding member 21 delimits a passage 22 in which the operating link 18 passes by retaining said operating link in the vicinity of the rim 17, the operating link 18 being permanently wound around the rim 17 between the shackle 19 and the holding member 21 on at least one arc-of-circle of non-zero length.

Cet organe de maintien 21 est, de manière simple, constitué d'une barrette transversale, parallèle à l'axe de rotation de la poulie 14 et s'étendant entre les deux flasques 15 et 16, à une faible distance radialement à l'extérieur de la jante 17, comme clairement représenté sur la figure 3.This holding member 21 is, in a simple manner, consisting of a transverse bar, parallel to the axis of rotation of the pulley 14 and extending between the two flanges 15 and 16, at a short distance radially outwardly. of the rim 17, as clearly depicted on the figure 3 .

Classiquement, la poulie est obtenue par moulage ou par injection d'une matière plastique et l'organe de maintien est alors venu de fabrication en même temps que la poulie (l'organe de maintien et la poulie sont alors d'une seule pièce).Conventionally, the pulley is obtained by molding or by injection of a plastic material and the holding member is then manufactured at the same time as the pulley (the holding member and the pulley are then in one piece) .

Selon une variante de réalisation non représentée sur les figures, l'organe de maintien 21 est constitué par une pièce qui est rapportée sur la poulie 14, et cette pièce est maintenue en position par exemple, par emboîtage, clipsage, ou analogue.According to an alternative embodiment not shown in the figures, the holding member 21 is constituted by a piece which is attached to the pulley 14, and this piece is held in position for example, by fitting, clipping, or the like.

On remarque également que l'organe de maintien 21 est positionné sur la poulie 14 selon une position sensiblement diamétralement opposée par rapport à la position du dispositif d'accrochage 19.Note also that the holding member 21 is positioned on the pulley 14 in a substantially diametrically opposite position relative to the position of the attachment device 19.

De cette manière, la poulie 14 ainsi obtenue est une pièce totalement symétrique, et elle peut être montée indifféremment d'un côté ou de l'autre du tube d'enroulement 3, grâce à une opération de retournement de la poulie sur elle-même par rapport à un plan passant à la fois par son axe de rotation et par le dispositif d'accrochage et l'organe de maintien.In this way, the pulley 14 thus obtained is a totally symmetrical part, and it can be mounted indifferently on one side or the other of the winding tube 3, thanks to a turning operation of the pulley on itself relative to a plane passing through both its axis of rotation and by the attachment device and the holding member.
