Description

L'invention se rattache au secteur technique des appareils distributeurs de matériau d'essuyage du type papier ouaté pour des applications essuie-mains, papier toilette, essuyage et nettoyage en général.The invention relates to the technical sector of devices tissue paper wiping material dispensers for hand towel, toilet paper, wiping and cleaning applications in general.

Le demandeur a développé de nombreux appareils de ce type qui comprennent, de manière usuelle, un carter, un capot, un tambour avec lame de coupe intégrée, ladite lame étant susceptible de sortir du tambour en fonctionnement grâce à des moyens de lancement et de rappel du tambour incluant un excentrique et un ressort de lancement de rappel disposés à partir d'un côté latéral du tambour. Des flasques latéraux du carter sont agencés pour supporter la bobine de matériau qui vient soit en appui direct sur le tambour selon l'enseignement du brevet FR 2.332.215, soit dans un plan au-dessus du tambour sans contact avec celui-ci, comme par exemple dans la réalisation décrite dans le brevet FR 99.13691.The applicant has developed numerous devices of this type which usually include a housing, a cover, a drum with blade integrated cutting, said blade being capable of coming out of the drum in operation by means of launching and recalling the drum including an eccentric and a return launch spring arranged at from one side of the drum. Side flanges of the housing are arranged to support the reel of material which comes into direct contact on the drum according to the teaching of patent FR 2,332,215, either in a plane above the drum without contact with it, for example in the embodiment described in patent FR 99.13691.

Dans ce genre d'appareil, la découpe d'une bande de matériau s'effectue par traction manuelle de l'utilisateur. En conséquence, la force de traction peut varier dans son importance et dans son orientation. De ce fait, peut se produire l'apparition de boucle entre la bobine de matériau et le point de contact entre le tambour récepteur du dispositif de coupe avec un moyen presseur complémentaire permettant l'appui de la bande de matériau. Cette apparition de boucle est gênante et le demandeur a développé déjà plusieurs solutions de dispositifs anti-boucle pour remédier à ces inconvénients. On cite par exemple les enseignements des brevets français suivants : FR 8903416 et FR 9805866.In this type of device, cutting a strip of material is carried out by manual traction of the user. As a result, the strength of traction can vary in its importance and in its orientation. Thereby, Loop may occur between the material reel and the point of contact between the receiving drum of the cutting device with a additional pressing means allowing the support of the strip of material. This appearance of a loop is troublesome and the applicant has already developed several solutions of anti-loop devices to remedy these disadvantages. We cite for example the lessons of French patents following: FR 8903416 and FR 9805866.

La démarche du demandeur a été de s'orienter vers une nouvelle conception et simplification du dispositif anti-boucle pouvant s'adapter à tout type d'appareil distributeur de matériau essuie-mains, papier toilette et autres, du type où la bobine est montée en appui sur le tambour, ou en non appui sur ce dernier.The applicant's approach was to move towards a new design and simplification of the anti-loop device that can be adapted to any type of device for dispensing paper towels, toilet paper and others, of the type where the coil is mounted in abutment on the drum, or not support on the latter.

La solution imaginée par le demandeur répond d'une manière simplifiée au problème posé.The solution imagined by the applicant responds in a way simplified to the problem posed.

Selon une première caractéristique de l'invention, le flasque porte-bobine dans un appareil distributeur de matériau d'essuyage, du type comprenant un bâti support recevant un couvercle de protection, ledit bâti présentant deux flasques entre lesquels sont disposés la bobine de matériau, le tambour récepteur du dispositif de coupe, et d'éventuels autres composants, les flasques porte-bobine recevant chacun un embout récepteur du mandrin de la bobine, est remarquable en ce que l'un des flasques recevant dans sa zone supérieure un axe support d'embout, et en ce que l'embout reçoit un joint torique faisant saillie et coopérant avec le mandrin de la bobine, et en ce que un moyen de rappel élastique est disposé entre la base dudit flasque ou l'entretoise de liaison associée des flasques pour assurer une fonction anti-boucle, en coopérant avec des moyens autorisant la mise en tension du moyen de rappel. According to a first characteristic of the invention, the spool holder flange in a device for dispensing wiping material, of the type comprising a support frame receiving a protective cover, said frame having two flanges between which the coil of material is arranged, the receiving drum of the cutting device, and any other components, the spool holder flanges each receiving a receiving end of the coil core, is remarkable in that one of the flanges receiving in its upper zone a tip support axis, and in that the end piece receives an O-ring protruding and cooperating with the mandrel of the coil, and in that an elastic return means is disposed between the base of said flange or the associated connecting spacer of the flanges for ensure an anti-loop function, by cooperating with means authorizing the tensioning of the return means.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will become apparent from the following the description.

    • Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is described now in a nonlimiting manner illustrated in the figures of the drawings.

    L'appareil distributeur de matériau d'essuyage, pour essuie-mains, papier toilette et autres, est référencé dans son ensemble par (1). Il comprend un bâti support (2) comprenant successivement une face de fond (2a) et une face inférieure (2b) à partir de laquelle est articulé un couvercle (3) de protection. Le bâti support présente deux flasques (4 - 5) entre lesquels sont disposés la bobine de matériau (b), le tambour récepteur du dispositif de coupe de la bande de matériau. Le tambour n'est pas représenté aux dessins, ainsi que d'autres pièces et composants qui peuvent, le cas échéant, être intégrés dans l'appareil distributeur et qui, en l'espèce, ne font pas partie directement de l'invention et en particulier dans la fonctionnalité de celle-ci. C'est la raison pour laquelle les dessins établis illustrent essentiellement les éléments nécessaires à la compréhension de l'invention.The device for dispensing wiping material, for hand towels, toilet paper and others, is referenced as a whole by (1). he comprises a support frame (2) successively comprising a bottom face (2a) and a lower face (2b) from which is hinged a cover (3) protection. The support frame has two flanges (4 - 5) between which are arranged the material reel (b), the receiving drum of the device for cutting the strip of material. The drum is not shown to the drawings, as well as other parts and components which may, if if necessary, be integrated in the dispensing device and which, in this case, do not not part directly of the invention and in particular in functionality of it. This is the reason why the established drawings illustrate essentially the elements necessary for understanding the invention.

    Le flasque (4) est disposé fixement sur l'un des côtés de l'appareil. Il est rapporté et fixé au bâti de celui-ci par encliquetage ou autre moyen de liaison temporaire. La partie supérieure du flasque est agencée pour recevoir un axe horizontal (6) se prolongeant par un embout (7) susceptible de pénétrer dans le mandrin support (8) de la bobine (b).The flange (4) is fixedly arranged on one side of the device. he is attached and fixed to the frame thereof by snap-fastening or other means of temporary liaison. The upper part of the flange is arranged to receive a horizontal axis (6) extending by a tip (7) capable of penetrate into the support mandrel (8) of the coil (b).

    Selon l'invention, et dans une première mise en oeuvre, l'autre flasque (5) disposé dans le même plan que le flasque (4) comprend deux parties (5.1 - 5.2). Une première partie ou base à position fixe et susceptible d'autoriser la fixation d'un côté de composants connus, tels que un tambour, un rouleau presseur, un rouleau de sécurité ou autres. Cette partie fixe se prolonge vers le haut par une partie (5.2) qui est avantageusement articulée à la précédente pour être écartée vers l'extérieur selon une angulation suffisante α pour l'insertion de la bobine de matériau sur les embouts porteurs. Cette partie (5.2) est articulée à sa base par rapport à (5.1) à l'aide d'un axe d'articulation (8) du type tige, monté et guidé le long de la zone supérieure de la partie fixe (5.1) du flasque. La partie articulée (5.2) reçoit, dans sa zone supérieure, un axe (9) se prolongeant par un embout (10) disposé en alignement axial avec l'embout précédent pour permettre la tenue de la bobine de matériau précitée. L'axe (9) de l'embout reçoit sur sa partie extérieure une couronne crantée (11) qui est susceptible de coopérer avec une couronne sous-jacente crantée (12) montée sur un axe (13) solidaire de la partie articulée (5.2) du flasque (5). Cette couronne sous-jacente (12) présente un point de saillie (12.1) débordant de côté intérieur et autorisant la fixation de l'extrémité (13.1) d'un moyen élastique de rappel (13). L'autre extrémité (13.2) dudit moyen (13) est fixée sur un plan fixe, soit formé sur la partie fixe du flasque (5), soit sur une barre de liaison entretoise (15) entre les flasques (4 et 5). Ce moyen de rappel peut être un ressort à boudins ou une languette flexible. La position de ce moyen est telle qu'il participe au basculement d'ouverture de la partie (5.2) articulée du flasque (5). La couronne crantée (12) est établie selon un rapport dimensionnel de 2 à 3 fois le diamètre de la couronne (11).According to the invention, and in a first implementation, the other flange (5) arranged in the same plane as the flange (4) comprises two parts (5.1 - 5.2). A first part or base with fixed position and susceptible authorize the attachment of one side of known components, such as a drum, a pressure roller, a safety roller or others. This fixed part is extends upwards by a part (5.2) which is advantageously articulated to the previous one to be spread outwards at an angle sufficient α for insertion of the material reel on the end caps carriers. This part (5.2) is articulated at its base with respect to (5.1) using a rod-type hinge pin (8), mounted and guided along the area upper part of the fixed part (5.1) of the flange. The articulated part (5.2) receives, in its upper zone, an axis (9) extending by a nozzle (10) arranged in axial alignment with the previous nozzle to allow the holding of the above-mentioned reel of material. The axis (9) of the nozzle receives on its outer part a notched crown (11) which is capable of cooperating with an underlying notched crown (12) mounted on an axis (13) secured to the articulated part (5.2) of the flange (5). This underlying crown (12) has a point of projection (12.1) projecting from the inside and authorizing the fixing of the end (13.1) of an elastic return means (13). The other end (13.2) of said means (13) is fixed on a fixed plane, either formed on the fixed part of the flange (5), or on a connecting bar spacer (15) between the flanges (4 and 5). This reminder can be a coil spring or flexible tab. The position of this means is such that it participates in the opening tilting of the articulated part (5.2) of the flange (5). The notched crown (12) is established according to a ratio 2 to 3 times the diameter of the crown (11).

    Ainsi, une première fonction du moyen (13) est de ramener en position le flasque (5) et en particulier dans la position de la figure 2.Thus, a first function of the means (13) is to bring back to position the flange (5) and in particular in the position of FIG. 2.

    Ce moyen (13) établi sous forme de ressort, par exemple, est disposé pour être situé sensiblement en regard de la partie fixe du flasque (5), tandis que ses extrémités sont accrochées selon une longueur plus ou moins importante à la barre entretoise et à la couronne dentée (12).This means (13) established in the form of a spring, for example, is arranged to be located substantially opposite the fixed part of the flange (5), while that its ends are hung more or less important to the spacer bar and to the crown gear (12).

    Selon une autre mise en oeuvre du flasque (5), celui-ci est réalisé avec une certaine élasticité et flexibilité permettant son écartement par son extrémité supérieure pour l'introduction de la bobine de matériau. Dans ce cas, la base du flasque (5) peut permettre la fixation d'une extrémité du moyen de rappel, tandis que sa partie supérieure est agencée pour la réception des moyens autorisant la fonction anti-boucle rappelée précédemment.According to another implementation of the flange (5), it is produced with a certain elasticity and flexibility allowing its spacing by its upper end for the introduction of the material reel. In this case, the base of the flange (5) can allow the attachment of one end of the return means, while its upper part is arranged for the reception of the means authorizing the recalled anti-loop function previously.

    Selon une autre disposition avantageuse de l'invention, la bobine disposée sur le flasque articulé présente un joint torique (14) faisant légèrement saillie et contribuant à la liaison de la bobine de matériau sur l'embout en provoquant, lors de la rotation de la bobine, la rotation de l'embout. Ainsi, lorsqu'il y a une traction de la bande de matériau pour un format donné, hors de l'appareil, la distribution d'un format de matériau entraíne la rotation de la bobine sur elle-même, et donc en particulier de l'embout (10) porteur du joint torique. Cela entraíne une rotation du couple de couronnes dentées (11 - 12) disposés sur le flasque articulé. La couronne inférieure (12), de par sa rotation sur elle-même, provoque le déplacement correspondant du point de fixation supérieur du moyen de rappel et ainsi sa mise en tension. Lorsque l'effort, sur la bande de papier, est relâchée, par simple détente élastique du moyen de rappel, la bobine de matériau revient en arrière en absorbant et supprimant l'effet de boucle résultant d'une trop importante rotation de la bobine de matériau sur elle-même. Le rapport dimensionnel particulier de 2 à 3 des couronnes entre elles fait que le matériau est toujours en tension.According to another advantageous arrangement of the invention, the coil arranged on the articulated flange has an O-ring (14) making slightly protruding and contributing to the binding of the material reel on the nozzle by causing, during the rotation of the coil, the rotation of the mouthpiece. So when there is a pull of the strip of material for a given format, outside the device, the distribution of a material format causes the coil to rotate on itself, and therefore in particular the end piece (10) carrying the O-ring. This results in torque rotation toothed crowns (11 - 12) arranged on the articulated flange. The crown lower (12), by its rotation on itself, causes displacement corresponding to the upper fixing point of the return means and thus its tensioning. When the effort, on the strip of paper, is released, by simple elastic relaxation of the return means, the material reel returns backwards by absorbing and suppressing the looping effect resulting from too significant rotation of the material reel on itself. The report particular dimensional of 2 to 3 of the crowns between them makes that the material is still under tension.

    Le moyen élastique de rappel est avantageusement un ressort à boudins mais il peut être aussi réalisé sous forme de languette flexible ou équivalent. La solution apportée est donc simple à réaliser. Le moyen de rappel assure ainsi une double fonction, à la fois de rappel en position fermeture de la partie supérieure (5.2) du flasque (5), et surtout la fonction anti-boucles par un retour de la bobine sur elle-même en cas de suppression de l'effort de traction de l'utilisateur, et par simple détente du moyen de rappel. A titre complémentaire, une butée d'arrêt fixe (16) est rendue solidaire de la partie supérieure, articulée ou non (5.2) du flasque (5). Une autre butée (17) est disposée sur la couronne (12) et tourne donc avec celle-ci. Ces deux butées (16 - 17) ont pour fonction de limiter la rotation de la couronne (12) en venant en contact l'une l'autre en faisant ainsi office de limiteur de course. Ainsi, il ne peut y avoir de rotation sur un tour de la couronne (12) et le moyen de rappel reste contrôlé sans risque d'enroulement autour de l'embout en regard.The elastic return means is advantageously a spring with tubes but it can also be produced in the form of a flexible tongue or equivalent. The solution provided is therefore simple to carry out. Way to recall thus performs a dual function, both recalling the position closing the upper part (5.2) of the flange (5), and especially the function anti-loop by a return of the coil on itself in case of removal of the user's tensile force, and by simply relaxing the means of reminder. In addition, a fixed stop (16) is made integral with the upper part, articulated or not (5.2) of the flange (5). A another stop (17) is arranged on the crown (12) and therefore rotates with the latter. These two stops (16 - 17) have the function of limiting the rotation of the crown (12) coming into contact with each other thereby acting as stroke limiter. Thus, there can be no rotation on one revolution of the crown (12) and the return means remains safely controlled winding around the facing end piece.

    Les avantages de cette mise en oeuvre sont évidents : la simplicité, le coût de fabrication et de montage des composants. Le ressort de rappel peut être choisi dans sa mise en oeuvre pour réguler l'effort de traction et de ré-embobinage. Le ressort de rappel peut être réalisé sous forme d'une languette flexible réalisée en un matériau qui ne soit pas destructible lors des nombreuses manipulations de chargement et rechargement de la bobine de matériau dans l'appareil.The advantages of this implementation are obvious: the simplicity, the cost of manufacturing and mounting the components. The return spring can be chosen in its implementation to regulate the traction and rewinding effort. The return spring can be produced in the form of a flexible tongue made of a material which is not destructible during numerous handling procedures for loading and reloading the reel of material in the device.

    Selon un autre avantage de l'invention, les couronnes (11 - 12) peuvent tourner dans les deux sens puisqu'il n'y a aucun moyen de contrôle du sens de rotation. Cela permet le positionnement de la bobine de matériau dans les deux sens. Quel que soit le sens de montage de la bobine, les butées d'arrêt (16 - 17) limitent la rotation des couronnes entre elles.According to another advantage of the invention, the crowns (11 - 12) can rotate in both directions since there is no means of control of the direction of rotation. This allows positioning of the material reel in both ways. Whatever the direction of assembly of the coil, the stops stop (16 - 17) limit the rotation of the crowns between them.
