Description

La présente invention concerne un dis tributeur antivol pour bande de matériau en rouleau et plus particulièrement un distributeur pour papier hygiénique ou papier d'essuyage en rouleau sans mandrin.The present invention relates to an anti-theft dispenser for a strip of material in a roll and more particularly a dispenser for toilet paper or wiping paper in a roll without a mandrel.

La présente invention concerne également un dispositif adaptateur antivol pour distributeur de bande de matériau en rouleau, en particulier pour distributeur antivol de bande de papier hygiénique ou de papier d'essuyage en rouleau avec mandrin.The present invention also relates to an anti-theft adapter device for a strip dispenser of rolled material, in particular for an anti-theft dispenser of a strip of toilet paper or of wiping paper roll with a mandrel.

Dans un but de simplification de terminologie l'invention sera décrite en référence plus particulièrement à un distributeur pour papier hygiénique en rouleau sans pour autant y constituer une quelconque limitation.In order to simplify terminology, the invention will be described with reference more particularly to a dispenser for toilet paper roll without however constituting any limitation.

On a souvent constaté, notamment au sein des collectivités, des vols de rouleaux de papier hygiénique et la plupart des solutions proposées jusqu'à présent pour pallier ce problème - dont les conséquences sont désagréables aussi bien pour les usagers que pour les fournisseurs - se sont avérées être peu efficaces ou d'une utilisation incommode due notamment à l'utilisation de systèmes de verrouillage qui pouvaient être forcés, et de ce fait détériorés et dont les clefs pouvaient être égarées.Theft of toilet paper rolls has often been observed, particularly in communities, and most of the solutions proposed so far to overcome this problem - the consequences of which are unpleasant for both users and suppliers - have proven to be ineffective or inconvenient to use due in particular to the use of locking systems which could be forced, and thereby deteriorated and whose keys could be lost.

L'US-A-3792822 décrit un support antivol pour rouleaux de papier avec mandrin comprenant un arbre cylindrique en acier sur lequel es t monté un mandrin muni de plusieurs dents à pointe acérée faisant saillie puis pénétrant dans le mandrin du rouleau de papier. La longueur totale de l'arbre cylindrique en acier est au moins égale à la longueur du mandrin du rouleau de papier.US-A-3792822 describes an anti-theft support for paper rolls with mandrel comprising a cylindrical steel shaft on which is mounted a mandrel provided with several teeth with sharp point protruding then penetrating into the mandrel of the paper roll. The total length of the cylindrical steel shaft is at least equal to the length of the paper roll core.

Ce système de l'US-A-379822 présente certains inconvénients, notamment celui de ne pouvoir être valablement utilisé avec des rouleaux de papier sans mandrin. En effet la mise en place du rouleau provoquerait un déchirement d'une partie importante du rouleau, sinon le dispositif ne pourrait remplir sa fonction antivol car il y aurait trop de jeu entre l'arbre cylindrique et la partie creuse du rouleau.This system of US-A-379822 has certain drawbacks, in particular that of being unable to be validly used with paper rolls without a mandrel. Indeed the establishment of the roller would cause a tearing of a large part of the roller, otherwise the device could not fulfill its anti-theft function because there would be too much play between the cylindrical shaft and the hollow part of the roller.

Or, les rouleaux sans mandrin deviennent de plus en plus largement utilisés notamment pour le papier hygiénique. De tels rouleaux sans mandrin pour bande de papier hygiénique sont avantageusement obtenus selon le procédé décrit dans le FR-A-2554799.However, rolls without a mandrel are becoming more and more widely used, in particular for toilet paper. Such rolls without mandrel for toilet paper strip are advantageously obtained according to the process described in FR-A-2554799.

De plus, on a également noté un fréquent déroulement intempestif des rouleaux, entraînant un gaspillage et nécessitant une recharge fréquente.In addition, there was also a frequent untimely unwinding of the rollers, resulting in waste and requiring frequent recharging.

Le dispositif décrit dans l'US-A-3792822 ne permet pas non plus de pallier ce dernier inconvénient.The device described in US-A-3792822 also does not overcome this latter drawback.

Un objet de la présente invention est de fournir un distributeur antivol pour bande de matériau en rouleau sans mandrin efficace et simple à utiliser.An object of the present invention is to provide an effective and simple to use anti-theft dispenser for strip of roll material without mandrel.

Un autre objet de l'invention est de fournir un distributeur antivol pour bande de matériau en rouleau permettant d'éviter des déroulements intempestifs du matériau du rouleau, à la fois pour des rouleaux avec mandrin et pour des rouleaux sans mandrin.Another object of the invention is to provide an anti-theft distributor for a strip of roll material making it possible to avoid unwanted unwinding of the roll material, both for rolls with mandrel and for rolls without mandrel.

Un objet de l'invention est de fournir un adaptateur antivol pour dis tributeur de bande de papier en rouleau permettant d'utiliser un distributeur pour rouleaux de papier sans mandrin avec des rouleaux de papier avec mandrin.It is an object of the invention to provide an anti-theft adapter for a dispenser for a rolled paper strip, making it possible to use a dispenser for paper rolls without a core with paper rolls with a core.

Le distributeur pour bande de matériau en rouleau sans mandrin représenté dans les Figures 1, 2 et 3 comprend une partie support sensiblement plane (1), un axe (2), destiné à assurer le support du rouleau, fixe, solidaire et perpendiculaire par rapport à ladite partie support (1), et un moyen anti-retrait compressible (3) monté en rotation axiale sur ledit axe (2) perpendiculairement à ladite partie support (1) empêchant le retrait du rouleau dans un sens opposé à ladite partie support (1), caractérisé par le fait que ledit moyen anti-retrait compressible (3) comprend une pluralité de bagues anti-retrait compressibles souples (4). Le diamètre intérieur des bagues anti-retrait (4) est ajustable. Le choix approprié du diamètre intérieur ⌀₂ de chacune desdites bagues anti-retrait (4) permet d'assurer, le cas échéant en combinaison avec la forme éventuellement tronconique dudit arbre (2), une fonction de freinage modulable du distributeur pour empêcher un déroulement intempestif du rouleau.The dispenser for strip of roll material without mandrel shown in Figures 1, 2 and 3 includes a support part substantially flat (1), an axis (2), intended to support the roller, fixed, integral and perpendicular with respect to said support part (1), and a compressible anti-shrinkage means (3) mounted in axial rotation on said axis (2) perpendicular to said support part (1) preventing the withdrawal of the roller in a direction opposite to said support part (1), characterized in that said compressible anti-shrinkage means (3) comprises a plurality of anti rings - flexible compressible withdrawal (4). The inside diameter of the anti-shrink rings (4) is adjustable. The appropriate choice of the internal diameter ⌀₂ of each of said anti-shrink rings (4) makes it possible to ensure, if necessary in combination with the possibly frustoconical shape of said shaft (2), a modular braking function of the distributor to prevent unwinding untimely roll.

Le distributeur représenté dans la Figure 1 comprend également une coupelle (5) montée en rotation axiale autour dudit axe (2) positionnée contre ladite partie support (1). La coupelle (5), qui ne comprend pas de moyens anti-retrait, a notamment pour fonction d'éviter le frottement du rouleau (non représenté), engagé sur le distributeur, contre la partie support (1) et peut elle aussi assurer une fonction de freinage pour empêcher un déroulement intempestif du rouleau. Le distributeur représenté dans la Figure 1 comprend à son extrémité libre, une butée (6) ayant sensiblement la forme d'une ogive. Ladite butée en forme d'ogive (6) est fixe par rapport audit arbre (2) et assure le maintien de la coupelle (5) des bagues anti-retrait (4) sur l'arbre (2). La butée en forme d'ogive (6) a une forme éfilée pour faciliter l'engagement du rouleau (non représenté) sur le distributeur.The dispenser shown in Figure 1 also includes a cup (5) mounted in axial rotation around said axis (2) positioned against said support part (1). The cup (5), which does not include anti-shrinkage means, has in particular the function of preventing the friction of the roller (not shown), engaged on the dispenser, against the support part (1) and can also ensure a braking function to prevent unwanted unwinding of the roller. The distributor shown in Figure 1 comprises at its free end, a stop (6) having substantially the shape of a warhead. Said ogive-shaped stop (6) is fixed relative to said shaft (2) and maintains the cup (5) of the anti-shrink rings (4) on the shaft (2). The warp-shaped stop (6) has a tapered shape to facilitate the engagement of the roller (not shown) on the dispenser.

Lesdites bagues anti-retrait (4) sont par exemple des "rondelles" coniques (41) souples, dont les extrémités sont orientées vers ladite partie support, (1) comportant un nombre variable d'encoches définissant ainsi des languettes d'harponnage (42).Said anti-shrink rings (4) are, for example, flexible conical "washers" (41), the ends of which are oriented towards said support part, (1) comprising a variable number of notches, thus defining harpooning tongues (42 ).

A titre d'exemple, une bague anti-retrait compressible (4) peut comporter 6 encoches à 60° ayant chacune une largeur (e) égale à environ 1 mm.By way of example, a compressible anti-shrink ring (4) may include 6 notches at 60 ° each having a width (e) equal to approximately 1 mm.

Le nombre des bagues anti-retrait (4) n'est pas critique. Le distributeur de la Figure 1 donné à titre d'exemple comporte 3 bagues (4).The number of anti-shrink rings (4) is not critical. The distributor of Figure 1 given by way of example has 3 rings (4).

La compressibilité des différentes bagues anti-retrait (4) peut être variable ainsi que leur conicité définie par l'angle (a).The compressibility of the different anti-shrink rings (4) can be variable as well as their taper defined by the angle (a).

Le moyen anti-retrait (3) comprenant une pluralité de bagues compressibles (4) peut avoir une "enveloppe", c'est-à-dire une forme hors-tout, sensiblement cylindrique ou sensiblement tronconique.The anti-shrinkage means (3) comprising a plurality of compressible rings (4) may have an "envelope", that is to say an overall shape, substantially cylindrical or substantially frustoconical.

Selon un mode de réalisation avantageux le dispositif antivol selon l'invention du type de celui représenté sur la Figure 1 a une longueur totale inférieure à celle du rouleau qu'il est destiné à recevoir. La longueur du dispositif antivol peut être, de façon appropriée, égale à environ la moitié de celle du rouleau.According to an advantageous embodiment, the anti-theft device according to the invention of the type shown in FIG. 1 has a total length less than that of the roll that it is intended to receive. The length of the anti-theft device may suitably be approximately half that of the roll.

Le diamètre ⌀₁ de l'axe (2) est par exemple égal à environ 8 à 11 mm.The diameter ⌀₁ of the axis (2) is for example equal to approximately 8 to 11 mm.

Les distributeurs antivol pour bande de matériau du type de celui représenté sur la Figure 1 sont particulièrement bien adaptés pour des rouleaux de papiers sans mandrin. En effet le rouleau emmanché sur l'arbre (2) pénètre dans la butée en forme d'ogive (6) sans se déchirer et s'engage ensuite sur les bagues anti-retrait souples (4) qui se compriment dans le sens de l'introduction du rouleau et se déploient ensuite pour bloquer le rouleau sans détériorer le matériau enroulé.Anti-theft distributors for strip of material of the type shown in FIG. 1 are particularly well suited for paper rolls without a mandrel. Indeed the roller fitted on the shaft (2) penetrates into the warp-shaped stop (6) without tearing and then engages on the flexible anti-shrink rings (4) which compress in the direction of the introduction of the roll and then deploy to block the roll without damaging the wound material.

Selon une variante (non représentée), la coupelle (5) peut être remplacée par une bague anti-retrait (4).According to a variant (not shown), the cup (5) can be replaced by an anti-shrink ring (4).

Le distributeur antivol représenté dans la Figure 4 comprend une partie support (1), pouvant être un support mural ou un socle de carter, sensiblement plane, un axe (2) destiné à assurer le support du rouleau, fixe, solidaire et perpendiculaire par rapport à ladite partie support (1) et muni à son extrémité libre d'une butée (6), un moyen anti-retrait compressible (3) monté sur ledit axe (2) en rotation axiale perpendiculairement à ladite partie support (1) et muni de moyens anti-retrait compressibles (31), empêchant le retrait du rouleau dans un sens opposé à lad te partie support (1), caractérisé en ce que ledit moyen anti-retrait (3) comprend une butée (7) à son extrémité en regard de ladite partie support (1), en ce que ledit axe (2) est muni d'un ressort (8) entre la partie support (1) et son extrémité en regard de ladite partie support (1) et en ce qu'un ergot (9) est fixé perpendiculairement à ladite partie support (1) en regard de ladite butée (7).The anti-theft distributor shown in Figure 4 comprises a support part (1), which can be a wall support or a casing base, substantially planar, an axis (2) intended to support the roller, fixed, integral and perpendicular to to said support part (1) and provided at its free end with a stop (6), a compressible anti-shrinkage means (3) mounted on said axis (2) in axial rotation perpendicular to said support part (1) and provided compressible anti-shrinkage means (31), preventing withdrawal of the roller in a direction opposite to the support part (1), characterized in that said anti-shrinkage means (3) comprises a stop (7) at its end look of said support part (1), in that said axis (2) is provided with a spring (8) between the support part (1) and its end opposite said support part (1) and in that a lug (9) is fixed perpendicular to said support part (1) opposite said stop (7).

Pour mettre le rouleau en place, on l'enfile sur le moyen anti-retrait (3) par la butée (6), on visse dans le sens des aiguilles d'une montre en appuyant sur le moyen anti-retrait (3) dans le sens axial. Le moyen anti-retrait (3) ne peut alors tourner sur lui-même car le ressort (8) se comprime et la butée (7) vient en appui sur l'ergot (9).To put the roller in place, it is threaded onto the anti-shrinkage means (3) by the stop (6), it is screwed clockwise by pressing on the anti-shrinkage means (3) in the axial direction. The anti-shrinkage means (3) cannot then turn on itself because the spring (8) is compressed and the stop (7) comes to bear on the lug (9).

Une fois en place le rouleau ne peut plus être dévissé car le ressort (8) n'étant plus comprimé l'ergot (9) ne bloque plus la butée (7) et le moyen anti-retrait (3) tourne sur lui-même.Once in place the roller can no longer be unscrewed because the spring (8) is no longer compressed the lug (9) no longer blocks the stop (7) and the anti-shrinkage means (3) turns on itself .

Dans le mode de réalisation spécifiquement représenté dans la Figure 4 le moyen anti-retrait compressible (3) a la forme d'une vis mais ce dispositif peut être réalisé avec un dispositif antivol du type de celui représenté sur la Figure 1. Dans un tel cas l'ergot (9) est positionné sur la coupelle (5) ou bien, si le dispositif ne comporte pas une telle coupelle, sur la bague anti-retrait (4) se trouvant contre la partie support (1).In the embodiment specifically shown in Figure 4 the compressible anti-shrinkage means (3) has the shape of a screw but this device can be made with an anti-theft device of the type of that shown in Figure 1. In such a case the lug (9) is positioned on the cup (5) or, if the device does not include such a cup, on the non-shrink ring (4) located against the support part (1).

La Figure 5 représente un distributeur antivol selon un autre mode de réalisation de l'invention comprenant une partie support (1) pouvant être un support mural ou un socle de carter, sensiblement plane, un axe (2) perpendiculaire à ladite partie support (1), destiné à assurer le support du rouleau et un manchon (10), monté sur ledit axe (2) en rotation axiale perpendiculairement à ladite partie support (1) et, muni de moyens anti-retrait compressibles (11) empêchant le retrait du rouleau dans un sens opposé à ladite partie support (1) et comportant à son extrémité libre une butée (6), caractérisé par le fait qu'il comprend en outre un deuxième manchon souple (12), ayant sensiblement la forme d'une bague cylindrique, fixé en compression entre la butée (6) et l'extrémité du premier manchon (10) opposé à ladite partie support (1).Figure 5 shows an anti-theft dispenser according to another embodiment of the invention comprising a support part (1) which can be a wall support or a casing base, substantially planar, an axis (2) perpendicular to said support part (1 ), intended to ensure the support of the roller and a sleeve (10), mounted on said axis (2) in axial rotation perpendicular to said support part (1) and, provided with compressible anti-shrinkage means (11) preventing the withdrawal of the roller in a direction opposite to said support part (1) and comprising at its free end a stop (6), characterized in that it further comprises a second flexible sleeve (12), having substantially the shape of a ring cylindrical, fixed in compression between the stop (6) and the end of the first sleeve (10) opposite to said support part (1).

Les moyens anti-retrait (11) compressibles ont par exemple la forme de crochets d'harponnage dont les extrémités sont orientées vers ladite partie support (1).The compressible anti-shrinkage means (11) have, for example, the form of harpoon hooks the ends of which are oriented towards said support part (1).

Selon un autre mode de réalisation de l'invention (non représenté), il est fourni un distributeur antivol de bande de matériau en rouleau, en particulier de papier hygiénique, comprenant un axe destiné à recevoir le rouleau, muni d'éléments d'accrochage et comprenant une butée à son extrémité libre, fixé en rotation axiale perpendiculairement à une partie support sensiblement plane, caractérisé par le fait que ledit axe comprend en outre un manchon souple ayant sensiblement la forme d'une bague cylindrique fixé en compression contre ladite butée.According to another embodiment of the invention (not shown), there is provided an anti-theft distributor of a strip of roll material, in particular of toilet paper, comprising an axis intended to receive the roll, provided with hooking elements and comprising a stop at its free end, fixed in axial rotation perpendicular to a substantially planar support part, characterized in that said axis further comprises a flexible sleeve having substantially the shape of a cylindrical ring fixed in compression against said stop.

Dans la Figure 5, le rouleau (non représenté) est engagé sur la broche composée de l'axe (2), du manchon (10) muni des moyens anti-retrait compressibles (11) par la butée arrondie (6). Les moyens anti-retrait (11) interdisent le dégagement du rouleau jusqu'à consommation totale de la bande. Le manchon souple (12) coopère avec les moyens anti-retrait (11) et assure en outre une fonction de freinage, garantissant de plus le blocage en place du rouleau.In Figure 5, the roller (not shown) is engaged on the spindle composed of the axis (2), the sleeve (10) provided with compressible anti-shrinkage means (11) by the rounded stop (6). The anti-shrinkage means (11) prohibit the disengagement of the roller until total consumption of the strip. The flexible sleeve (12) cooperates with the anti-shrinkage means (11) and also provides a braking function, further guaranteeing the locking in place of the roller.

Selon un mode de réalisation avantageux de l'invention, la longueur totale du distributeur antivol pour bande de matériau en rouleau est inférieure à celle du rouleau.According to an advantageous embodiment of the invention, the total length of the anti-theft distributor for a strip of material in a roll is less than that of the roll.

La Figure 6 représente un dispositif adaptateur antivol (13) pour distributeur (14) de bande de matériau en rouleau (15) à manchon (10) en forme de harpon muni de moyens anti-retraits (11), comprenant des machoires (16) reliées à une tête arrêtoir (17) et caractérisé en ce que lesdites machoires (16) sont flexibles et en ce que la forme de la partie interne desdites machoires (16) est telle qu'elles puissent épouser la forme de la partie externe dudit manchon (10).Figure 6 shows an anti-theft adapter device (13) for a distributor (14) of a strip of rolled material (15) with a harpoon-shaped sleeve (10) provided with anti-shrinkage means (11), comprising jaws (16) connected to a stop head (17) and characterized in that said jaws (16) are flexible and in that the shape of the internal part of said jaws (16) is such that they can match the shape of the external part of said sleeve (10).

Au moment de l'utilisation on insère d'abord l'adaptateur dans le mandrin (18) du rouleau (15). Le diamètre (L) de la tête arrêtoir (17) doit être supérieur au diamètre ⌀₃ du mandrin utilisé. Les machoires flexibles (16) - qui ont été comprimées dans le sens des flèches (F1) - se détendent à l'intérieur du mandrin (18). Le rouleau (15) comprenant l'adaptateur (13) à l'intérieur de son mandrin (18) est alors emmanché sur le manchon (10) du distributeur (14) fixé sur la partie support (1). L'adaptateur (13) se trouve alors bloqué sur le manchon (10) à l'intérieur du mandrin (18).At the time of use, the adapter is first inserted into the mandrel (18) of the roller (15). The diameter (L) of the stop head (17) must be greater than the diameter ⌀₃ of the mandrel used. The flexible jaws (16) - which have been compressed in the direction of the arrows (F1) - relax inside the mandrel (18). The roller (15) comprising the adapter (13) inside its mandrel (18) is then fitted onto the sleeve (10) of the distributor (14) fixed on the support part (1). The adapter (13) is then blocked on the sleeve (10) inside the mandrel (18).

Les espaces entre les crochets (19) situés dans la partie interne des machoires (16) sont prévus de façon à épouser la forme des moyens anti-retrait (11) en forme de crochets du manchon (10).The spaces between the hooks (19) located in the internal part of the jaws (16) are provided so as to match the shape of the anti-shrinkage means (11) in the form of hooks of the sleeve (10).

Le rouleau (15) ne peut alors être enlevé de l'adaptateur avant que la bande de papier (20) ne soit épuisée car il est bloqué par la tête arrêtoir (17).The roller (15) cannot then be removed from the adapter before the paper strip (20) is exhausted because it is blocked by the stop head (17).

Quand la bande de papier (20) du rouleau (15) est épuisée, on peut enlever l'adaptateur (13) du mandrin (18) en découpant ce dernier. Il est également possible d'utiliser un rouleau à mandrin prédécoupé.When the paper strip (20) of the roll (15) is exhausted, the adapter (13) can be removed from the mandrel (18) by cutting the latter. It is also possible to use a pre-cut mandrel roller.

L'adaptateur antivol selon l'invention peut bien évidemment être utilisé avec un distributeur du type de celui représenté dans la Figure 1.The anti-theft adapter according to the invention can obviously be used with a dispenser of the type shown in FIG. 1.

La présente invention permet de disposer de distributeurs antivol de bande de matériau en rouleau utilisables, en liaison éventuellement avec un dispositif adaptateur antivol selon l'invention, à la fois avec des rouleaux sans mandrin et des rouleaux avec mandrin et assurant, si on le désire, une fonction de freinage évitant des déroulements intempestifs des rouleaux.The present invention makes it possible to have anti-theft distributors of strip of rollable material which can be used, optionally in connection with an anti-theft adapter device according to the invention, both with rolls without mandrel and rollers with mandrel and ensuring, if desired , a braking function preventing unwanted unwinding of the rollers.

Les modes de réalisation décrits ci-dessus ne sont donnés qu'à titre d'exemple et de nombreuses variantes peuvent être envisagées dans le cadre de la présente invention.The embodiments described above are given by way of example only and numerous variants can be envisaged within the framework of the present invention.
