Description

L'invention concerne un dévidoir de bandes continues à couper, appelé à permettre la distribution de longueurs désirées de bande selon le préambule de la revendication 1 (connu du brevet US-A-3 040 943). Elle s'applique en particulier pour la distribution de bandes de papier, tel que papier hygiénique, papier essuie-main etc.The invention relates to a reel of continuous strips to be cut, intended to allow the distribution of desired lengths of strip according to the preamble of claim 1 (known from US-A-3,040,943). It applies in particular for the distribution of paper strips, such as toilet paper, paper towels etc.

On connaît des dévidoirs de bande comprenant un boîtier dans lequel est logée la bande, une ouverture pour la sortie de celle-ci et un organe tranchant qui permet de couper la bande après traction de la longueur désirée ; la coupure de la bande s'effectue en appliquant celle-ci contre l'organe tranchant et en exerçant sur ladite bande une brusque traction appropriée.Tape dispensers are known comprising a housing in which the tape is housed, an opening for the outlet thereof and a cutting member which makes it possible to cut the tape after traction of the desired length; the strip is cut by applying it against the cutting member and by exerting on said strip a sudden suitable pull.

Pour que la coupure soit nette, il est essentiel que la brusque traction exercée sur la bande n'engendre pas de glissement de celle-ci le long de l'organe tranchant. Ainsi, le brevet GB-A-1 516 097 et le brevet US-A-3 040 943 prévoient une aile de coupe mobile qui provoque le blocage de la bande lorsqu'on opère la brusque traction de rupture sur celle-ci. Toutefois, l'aile de coupe mobile possède des moyens tranchants situés en saillie par rapport au dévidoir, qui s'avèrent en pratique dangereux pour les utilisateurs, notamment pour les enfants (lesquels peuvent être blessés au visage ou aux yeux compte-tenu de la hauteur habituelle à laquelle se trouve l'ouverture des dévidoirs).For the cut to be clear, it is essential that the sudden traction exerted on the strip does not cause it to slide along the cutting member. Thus, the patent GB-A-1,516,097 and the patent US-A-3,040,943 provide for a movable cutting wing which causes the blocking of the strip when the abrupt pull of rupture is effected thereon. However, the movable cutting wing has sharp means protruding from the reel, which prove in practice dangerous for users, especially for children (who may be injured in the face or in the eyes taking into account the usual height at which the reel opening is located).

En outre, il est utile que la bande soit freinée, de façon douce, au cours de la distribution lorsque l'utilisateur exerce une traction modérée sur celle-ci ; ce freinage doux a pour but d'éviter que des longueurs de bande plus importantes que nécessaire soient distribuées par inertie. C'est ainsi que le brevet US-A-3 040 943 déjà évoqué décrit un dispositif indépendant qui assure cette action de freinage. Ce dispositif est totalement indépendant de celui qui assure le blocage de la bande lors de la coupe, car les deux effets à obtenir sont totalement distincts et même opposés, l'un tendant à provoquer un blocage net de la bande en cours de coupure sans risque de glissement de celle-ci, de façon à autoriser une coupure nette et franche, l'autre tendant à opérer une action douce de freinage sur la bande en cours de traction sans risque de blocage, de façon à permettre une distribution correcte de celle-ci sans gaspillage ni déchirement.In addition, it is useful for the strip to be braked gently during distribution when the user exerts moderate traction on it; the purpose of this soft braking is to prevent lengths of strip greater than necessary from being distributed by inertia. Thus, the patent US-A-3,040,943 already mentioned describes an independent device which provides this braking action. This device is completely independent of the one which ensures the blocking of the strip during cutting, since the two effects to be obtained are completely distinct and even opposite, one tending to cause a net blocking of the strip during cutting without risk. of sliding thereof, so as to allow a clean and frank cut, the other tending to operate a gentle braking action on the strip being pulled without risk of blockage, so as to allow correct distribution thereof this without waste or tearing.

Par ailleurs, dans les dispositifs connus visant la distribution de bandes continues à couper, les bandes sont stockées dans les dévidoirs sous forme de rouleaux ; ce type de conditionnement limite considérablement la capacité qu'il est possible d'emmagasiner dans un dévidoir : en effet, dans un rouleau cylindrique, deux des trois dimensions sont obligatoirement égales et l'utilisation de très gros rouleaux imposerait des dévidoirs dont l'encombrement (important le long de deux dimensions) serait incompatible avec une mise en place dans les pièces sanitaires habituelles.Furthermore, in known devices for distributing continuous strips to be cut, the strips are stored in the reels in the form of rolls; this type of packaging considerably limits the capacity that it is possible to store in a reel: in fact, in a cylindrical roll, two of the three dimensions are necessarily equal and the use of very large rollers would require reels whose size (important along two dimensions) would be incompatible with installation in the usual sanitary rooms.

La présente invention se propose de fournir une solution perfectionnée au problème de la distribution de bandes continues à couper.The present invention proposes to provide an improved solution to the problem of distributing continuous strips to be cut.

Un objectif essentiel de l'invention est en particulier de fournir un dévidoir de structure simple, et donc peu coûteux, qui soit apte à engendrer une distribution régulière, sans gaspillage ni déchirement accidentel, permette une coupe nette et franche de la bande aux longueurs désirées, et ne suscite aucun danger pour l'utilisateur.An essential objective of the invention is in particular to provide a reel of simple structure, and therefore inexpensive, which is capable of generating a regular distribution, without waste or accidental tearing, allows a clean and frank cut of the strip at the desired lengths , and poses no danger to the user.

-A cet effet, l'invention vise notamment, dans un but de simplification, à assurer avec un même organe l'effet de freinage doux sans blocage lors de la distribution, et l'effet de blocage net sans glissement lors de la coupe.-To this end, the invention aims in particular, for the sake of simplification, to ensure with the same member the soft braking effect without blocking during distribution, and the net blocking effect without slipping during cutting.

Un autre objectif de l'invention est de fournir un dévidoir bénéficiant, à la fois, d'un encombrement compatible avec une mise en place dans des pièces sanitaires, notamment de lieux publics, et d'une capacité considérablement accrue par rapport aux dévidoirs connus.Another objective of the invention is to provide a reel benefiting both from a space requirement compatible with installation in sanitary rooms, in particular public places, and of a considerably increased capacity compared to known reels .

Un autre objectif est d'obtenir, après chaque coupure de la bande, une longueur de dépassement constante, facilitant ensuite la saisie de la bande lors de l'opération suivante de distribution et évitant les désamorçages de celle-ci.Another objective is to obtain, after each cut of the strip, a constant length of protrusion, then facilitating the gripping of the strip during the next dispensing operation and avoiding defusing the latter.

Un autre objectif est d'assurer une meilleure protection hygiénique de la bande à l'intérieur du dévidoir, en réduisant les risques de souillures de celle-ci par contact externe.Another objective is to ensure better hygienic protection of the strip inside the reel, by reducing the risks of soiling thereof by external contact.

Un autre objectif est de fournir un dévidoir se prêtant à des chargements faciles, tout en possédant un caractère inviolable à l'égard des personnes non habilitées.Another objective is to provide a dispenser suitable for easy loading, while having an inviolable nature with regard to unauthorized persons.

Le dévidoir de bandes continues à couper visé par l'invention est du type comprenant :

  • un boîtier adapté pour contenir une bande,
  • une ouverture de passage de l'extrémité de ladite bande,
  • une paroi de guidage, située au voisinage de l'ouverture et présentant une zone interne s'étendant vers l'intérieur du boîtier et un seuil à la sortie de celui-ci en bordure de l'ouverture,
  • une aile de coupe, portant des moyens tranchants et articulée au voisinage de l'ouverture autour d'un axe agencé pour lui permettre de pivoter entre une position naturelle de repos où elle se trouve située au voisinage du plan de ladite ouverture, et une position de coupe où ses moyens tranchants viennent se situer en saillie en regard dudit plan de l'ouverture.
The reel of continuous strips to be cut targeted by the invention is of the type comprising:
  • a housing adapted to contain a strip,
  • a passage opening at the end of said strip,
  • a guide wall, located in the vicinity of the opening and having an internal zone extending towards the inside of the housing and a threshold at the exit of the latter at the edge of the opening,
  • a cutting wing, carrying cutting means and articulated in the vicinity of the opening around an axis arranged to allow it to pivot between a natural position of rest where it is located in the vicinity of the plane of said opening, and a position cutting where its cutting means are located projecting opposite said plane of the opening.

Conformément à la présente invention, le dévidoir est caractérisé par la combinaison des caractéristiques suivantes :

  • une première aile auxiliaire est articulée autour d'un axe,
  • cette première aile auxiliaire comprend une portion de recouvrement s'étendant vers l'intérieur du boîtier au contact de la zone interne de la paroi de guidage, en vue de délimiter un chemin de passage pour la bande,
  • cette première aile auxiliaire comprend une portion de butée, agencée de sorte que, en position de coupe, l'aile de coupe vienne en butée et en pression contre ladite portion de butée,
  • ladite première aile auxiliaire est adaptée de sorte que, dans la position naturelle de repos de l'aile de coupe, sa portion de recouvrement vienne en appui contre la paroi de guidage pour assurer un effet de freinage de la bande dans le chemin de passage, et que, dans la position de coupe de ladite aile de coupe, ladite aile auxiliaire soit soumise, par l'effet de la pression exercée sur sa portion de butée, à un moment assurant un pincement et un blocage de la bande par sa portion de recouvrement à l'intérieur du chemin de passage,
  • une seconde aile auxiliaire est articulée autour d'un axe,
  • cette seconde aile auxiliaire est articulée autour d'un axe décalé par rapport à celui de l'aile de coupe, de façon à pouvoir pivoter entre deux positions : une position naturelle de repos correspondant à la position naturelle de repos de l'aile de coupe, dans laquelle cette aile auxiliaire passe à proximité du seuil de la paroi de guidage et sert d'appui à l'aile de coupe, et une position escamotée correspondant à la position de coupe de l'aile de coupe, dans laquelle ladite aile auxiliaire se trouve située en retrait par rapport à ladite aile de coupe et à ses moyens tranchants.
According to the present invention, the reel is characterized by the combination of the following characteristics:
  • a first auxiliary wing is articulated around an axis,
  • this first auxiliary wing comprises a covering portion extending towards the inside of the housing in contact with the internal zone of the guide wall, with a view to delimiting a passage path for the strip,
  • this first auxiliary wing includes a abutment portion, arranged so that, in the cutting position, the cutting wing comes into abutment and in pressure against said abutment portion,
  • said first auxiliary wing is adapted so that, in the natural rest position of the cutting wing, its covering portion comes to bear against the guide wall to ensure a braking effect of the strip in the passageway, and that, in the cutting position of said cutting wing, said auxiliary wing is subjected, by the effect of the pressure exerted on its abutment portion, to a moment ensuring pinching and blocking of the strip by its portion of covering inside the passage way,
  • a second auxiliary wing is articulated around an axis,
  • this second auxiliary wing is articulated around an axis offset from that of the cutting wing, so as to be able to pivot between two positions: a natural rest position corresponding to the natural rest position of the cutting wing , in which this auxiliary wing passes close to the threshold of the guide wall and serves as a support for the cutting wing, and a retracted position corresponding to the cutting position of the cutting wing, in which said auxiliary wing is located set back from said cutting wing and its cutting means.

Ainsi, le dispositif de l'invention possède trois ailes mobiles agencées pour remplir les fonctions respectives suivantes :

  • L'aile de coupe possède une double fonction :
    • en premier lieu, la fonction traditionnelle d'assurer la coupe en fin de course de son pivotement,
    • ensuite, une fonction nouvelle consistant à , transmettre à la première aile auxiliaire l'effort de rupture qui lui est communiqué par la bande.
Thus, the device of the invention has three movable wings arranged to fulfill the following respective functions:
  • The cutting wing has a double function:
    • firstly, the traditional function of ensuring the cut at the end of its pivoting stroke,
    • then, a new function consisting in transmitting to the first auxiliary wing the breaking force communicated to it by the strip.

La première aile auxiliaire possède la triple fonction :

  • d'assurer un freinage doux de la bande en cours de distribution,
  • de servir de butée à l'aile de coupe à la fin de son pivotement vers la position de coupe,
  • d'assurer un blocage de la bande lorsque l'effort de rupture lui est transmis.
The first auxiliary wing has the triple function:
  • ensure gentle braking of the strip during distribution,
  • to serve as a stop for the cutting wing at the end of its pivoting towards the cutting position,
  • block the strip when the breaking force is transmitted to it.

Enfin, la seconde aile auxiliaire possède la double fonction :

  • de servir d'appui et de protection à l'aile de coupe en position de repos,
  • de permettre aux moyens tranchants de prendre une position active saillante au cours du mouvement de l'aile de coupe vers la position de coupe.
Finally, the second auxiliary wing has the dual function:
  • to serve as support and protection for the cutting wing in the rest position,
  • to allow the cutting means to take an active projecting position during the movement of the cutting wing towards the cutting position.

Le montage de ces ailes avec leurs agencements confère au dispositif une structure mécanique très simple, il est à noter que les effets opposés de freinage doux et de blocage net sont produits par le même organe (première aile auxiliaire dont le blocage est asservi à la position de l'aile de coupe).The mounting of these wings with their arrangements gives the device a very simple mechanical structure, it should be noted that the opposite effects of soft braking and net blocking are produced by the same member (first auxiliary wing whose blocking is controlled by the position of the cutting wing).

De façon connue en soi, l'aile de coupe peut être sensiblement plane, ses moyens tranchants étant constitués par une découpe en dents de scie ménagée sur son bord extrême (opposé à son articulation) ; la seconde aile auxiliaire possède alors un retour agencé pour se disposer dans un plan coïncidant sensiblement avec le plan de l'aile de coupe dans la position naturelle de repos desdites ailes.In a manner known per se, the cutting wing can be substantially planar, its cutting means being constituted by a sawtooth cut formed on its extreme edge (opposite to its articulation); the second auxiliary wing then has a return arranged to be arranged in a plane substantially coinciding with the plane of the cutting wing in the natural rest position of said wings.

Dans cette position de repos, le bord tranchant de l'aile de coupe est ainsi accolé contre ce retour, sans débordement par rapport à celui-ci, et se trouve dans un état totalement inoffensif.In this rest position, the cutting edge of the cutting wing is thus joined against this return, without overflowing with respect thereto, and is in a completely harmless state.

En outre, dans un mode de réalisation préféré, l'ouverture de passage du boîtier est située dans un plan sensiblement vertical pour la position d'utilisation normale du dévidoir. (Par convention, tous les qualificatifs de position ou d'orientation indiqués dans la présente demande se réfèrent _à la position d'utilisation normale du dévidoir). Les divers organes du dévidoir présentent dans ce mode de réalisation les agencements suivants :

  • la paroi de guidage est sensiblement horizontale, son seuil étant proche du bord inférieur de l'ouverture,
  • la seconde aile auxiliaire est articulée au-dessus et au voisinage de la paroi de guidage, à l'arrière du seuil et est agencée pour venir, en position naturelle de repos, en appui sur le seuil par l'effet de son poids,
  • l'aile de coupe est articulée au voisinage et au-dessous du bord supérieur de l'ouverture et est agencée pour venir en position naturelle de repos, en appui contre la seconde aile auxiliaire par l'effet de son poids,
  • la première aile auxiliaire est articulée autour d'un axe commun avec celui de la seconde aile auxiliaire et possède une portion ascendante de jonction entre sa portion de recouvrement et sa portion de butée, ladite portion ascendante étant située à l'arrière de l'aile de coupe et reliée à la portion de butée au-dessus et à l'arrière de l'axe d'articulation de l'aile de coupe, ladite portion de butée formant en direction de l'ouverture une avancée située au-dessus de l'aile de coupe.
In addition, in a preferred embodiment, the passage opening of the housing is located in a substantially vertical plane for the normal use position of the reel. (By convention, all the position or orientation qualifiers indicated in this request refer to the normal use position of the reel). In this embodiment, the various components of the reel have the following arrangements:
  • the guide wall is substantially horizontal, its threshold being close to the lower edge of the opening,
  • the second auxiliary wing is articulated above and in the vicinity of the guide wall, at the rear of the threshold and is arranged to come, in a natural position of rest, bearing on the threshold by the effect of its weight,
  • the cutting wing is articulated in the vicinity and below the upper edge of the opening and is arranged to come into a natural rest position, pressing against the second auxiliary wing by the effect of its weight,
  • the first auxiliary wing is articulated around an axis common with that of the second auxiliary wing and has an ascending portion of junction between its covering portion and its abutment portion, said ascending portion being located at the rear of the wing of cutting and connected to the abutment portion above and behind the hinge axis of the cutting wing, said abutment portion forming in the direction of the opening a projection situated above the cutting wing.

De plus, la portion de recouvrement de la première aile auxiliaire peut avantageusement posséder, à l'opposé de l'ouverture, un prolongement lesté s'écartant de ladite paroi de guidage ; le lest est ajusté pour obtenir une pression adaptée de la portion de recouvrement contre la paroi de guidage afin d'assurer sur la-bande un freinage doux d'intensité appropriée.In addition, the covering portion of the first auxiliary wing may advantageously have, opposite the opening, a weighted extension deviating from said guide wall; the ballast is adjusted to obtain a suitable pressure of the covering portion against the guide wall in order to ensure soft braking of the appropriate intensity on the strip.

Ce mode de réalisation est avantageux par sa simplicité, du fait que les positions de repos ou de freinage doux des ailes sont obtenues par l'effet naturel de leur poids sans moyen de rappel surajouté.This embodiment is advantageous by its simplicity, because the rest or soft braking positions of the wings are obtained by the natural effect of their weight without additional return means.

Par ailleurs, selon une autre caractéristique de l'invention, le boîtier est adapté pour former, au-dessous de la paroi de guidage, un magasin apte à contenir une bande à l'état replié en accordéon.Furthermore, according to another characteristic of the invention, the housing is adapted to form, below the guide wall, a magazine capable of containing a strip in the folded-out accordion state.

Il peut ainsi avantageusement présenter la forme générale d'un parallélépipède rectangle allongé s'étendant verticalement, l'ouverture de passage ayant la forme d'une fente rectangulaire s'étendant au voisinage de l'extrémité supérieure du boîtier sur toute la largeur d'une face de celui-ci.It can thus advantageously have the general shape of an elongated rectangular parallelepiped extending vertically, the passage opening having the shape of a rectangular slot extending in the vicinity of the upper end of the housing over the entire width of one face thereof.

La section transversale d'un tel dévidoir peut ainsi posséder des dimensions relativement faibles : sa largeur est légèrement supérieure à celle de la bande continue (en particulier approximativement comprise entre 8 et 30 cm selon l'application) et sa profondeur qui correspond à la distance séparant les plis de la bande, peut être ajustée, de façon souple, en fonction de l'application de sorte que le boîtier forme une saillie acceptable par rapport au support contre lequel il est adossé (en particulier la profondeur peut être approximativement comprise entre 6 et 20 cm) ; la capacité du dévidoir peut aisément présenter des valeurs très importantes, simplement en prévoyant une hauteur appropriée de celui-ci. Cette hauteur peut facilement aller jusqu'à 1,5 mètre sans soulever de difficultés pratiques de mise en place, en raison de la forme allongée, étroite et peu profonde du dévidoir, qui permet en pratique de loger très commodément celui-ci dans les sanitaires de lieux accessibles au public (cinémas, restaurants, gares, aéroports, établissements hospitaliers, collectivités publiques ou privées).The cross section of such a reel can thus have relatively small dimensions: its width is slightly greater than that of the continuous strip (in particular approximately between 8 and 30 cm depending on the application) and its depth which corresponds to the distance separating the pleats from the strip, can be flexibly adjusted according to the application so that the housing forms an acceptable projection relative to the support against which it is leaning (in particular the depth can be approximately between 6 and 20 cm); the capacity of the reel can easily present very important values, simply by providing an appropriate height thereof. This height can easily go up to 1.5 meters without raising practical difficulties of installation, due to the elongated, narrow and shallow shape of the reel, which in practice allows it to be very conveniently housed in the sanitary places accessible to the public (cinemas, restaurants, stations, airports, hospitals, public or private communities).

Il est ainsi possible de stocker dans le dévidoir des longueurs de bandes considérables (aisément jusqu'à 800 à 1 000 m), ceci étant totalement inenvisageable avec les dévidoirs à rouleaux classiques (qui présenteraient des diamètres totalement redhibitoires). A titre indicatif, les plus grands dévidoirs à rouleaux pour sanitaire peuvent stocker entre 130 et 140 m de bandes de papier pour essuie-main.It is thus possible to store considerable lengths of tape in the reel (easily up to 800 to 1000 m), this being totally unthinkable with conventional reels with rollers (which would have totally prohibitive diameters). As an indication, the largest rollers for sanitary rollers can store between 130 and 140 m of strips of paper for towels.

Cette considérable augmentation des capacités possibles est un avantage essentiel en pratique, car elle entraîne une réduction de la fréquence des chargements et une réduction du coût de l'unité de longueur de bande (en raison d'un conditionnement par quantités plus importantes). De plus, les bandes qui se présentent sous la forme de parallélépipèdes rectangles sont plus faciles à stocker que des rouleaux cylindriques qui entraînent des pertes de place.This considerable increase in possible capacities is an essential advantage in practice, since it results in a reduction in the frequency of loading and a reduction in the cost of the unit of tape length (due to packaging in larger quantities). In addition, the strips which are in the form of rectangular parallelepipeds are easier to store than cylindrical rollers which cause space losses.

finally, FIGS. 6a, 6b, 6c and 6d are diagrams illustrating the operation of the reel.

Le dévidoir représenté à titre d'exemple aux figures 1, 2 et 3 est un dévidoir de grande capacité destiné à la distribution de longueurs de papier servant d'essuie-main ; il peut être utilisé dans tout local sanitaire (public ou privé) appelé à être fréquenté par un certain nombre de personnes.The dispenser shown by way of example in FIGS. 1, 2 and 3 is a large capacity dispenser intended for the distribution of lengths of paper used as a hand towel; it can be used in any sanitary area (public or private) which is expected to be frequented by a certain number of people.

Ce dévidoir comprend un boîtier 1 ayant la forme générale d'un parallélépipède rectangle allongé, s'étendant verticalement et de hauteur totale - H - d'environ 85 cm, de largeur - 1 - d'environ 25 cm et de profondeur - p - d'environ 11 cm.This reel comprises a housing 1 having the general shape of an elongated rectangular parallelepiped, extending vertically and of total height - H - of approximately 85 cm, of width - 1 - of approximately 25 cm and of depth - p - about 11 cm.

Ce boîtier comprend en partie haute des moyens 2 de distribution de bande qui seront décrits plus loin ; au-dessous de ces moyens 2, le boîtier forme un magasin 3 adapté pour contenir une bande de papier 4 dont la largeur - l' - est légèrement inférieure à celle du dévidoir (de l'ordre de 24 cm) et qui est repliée en accordéon avec des plis distants d'une distance - e - légèrement inférieure à la profondeur - p - du dévidoir (de l'ordre de 10 cm).This housing comprises in the upper part means 2 for strip distribution which will be described later; below these means 2, the box forms a magazine 3 adapted to contain a strip of paper 4 whose width - l '- is slightly less than that of the reel (of the order of 24 cm) and which is folded in accordion with folds distant by a distance - e - slightly less than the depth - p - from the reel (of the order of 10 cm).

Le magasin du dévidoir présente en exemple une hauteur d'environ 70 cm, ce qui permet d'y loger une bande repliée en accordéon, d'une longueur totale d'environ 600 m.The reel store has, for example, a height of around 70 cm, which allows it to accommodate an accordion-folded strip, with a total length of around 600 m.

Le boîtier 1 est formé de deux parties qui sont articulées l'une sur l'autre en partie basse : un caisson 5 de section transversale en forme de U et une plaque arrière 6 adaptée pour être fixée contre un support, par exemple une paroi murale. (Pour simplifier la description, on adoptera par la suite comme sens avant arrière le sens allant du caisson 5 vers la plaque 6).The housing 1 is formed of two parts which are articulated one on the other in the lower part: a box 5 of U-shaped cross section and a back plate 6 adapted to be fixed against a support, for example a wall wall . (To simplify the description, the direction going from the box 5 towards the plate 6 will be adopted as the front-rear direction).

La plaque arrière 6 comporte le long de ses arêtes longitudinales verticales des rebords tels que 6a, que vient chevaucher le caisson 5 en position de fermeture.The rear plate 6 has along its vertical longitudinal edges edges such as 6a, which overlaps the box 5 in the closed position.

En outre, en partie haute, cette plaque arrière est dotée, de part et d'autre, de flasques latéraux tels que 6b qui sont fixés par rivetage sur les retours 6a. Ces flasques qui viennent se loger au voisinage des parois latérales du caisson lorsque celui-ci est fermé, maintiennent les organes essentiels des moyens de distribution 2, comme on le verra plus loin.In addition, in the upper part, this rear plate is provided, on both sides, with lateral flanges such as 6b which are fixed by riveting to the returns 6a. These flanges which are housed in the vicinity of the side walls of the box when the latter is closed, maintain the essential organs of the distribution means 2, as will be seen below.

De plus, en partie basse, la plaque arrière 6 est dotée d'un retour 6c qui soutient la bande 4 disposée dans le magasin, et de deux flasques latéraux inférieurs 6d, fixés de part et d'autre sur ledit retour 6c et sur les rebords 6a.In addition, in the lower part, the rear plate 6 is provided with a return 6c which supports the strip 4 arranged in the magazine, and with two lower lateral flanges 6d, fixed on either side on said return 6c and on the ledges 6a.

Le caisson 5 est constitué par une paroi frontale 5a, deux parois latérales 5b, 5c et une paroi supérieure 5d qui le ferme en partie haute. La paroi frontale comporte en partie basse une fenêtre 14 en matériau transparent, qui permet au préposé de savoir immédiatement si le dévidoir doit être rechargé ou non.The box 5 is constituted by a front wall 5a, two side walls 5b, 5c and an upper wall 5d which closes it in the upper part. The front wall has in the lower part a window 14 made of transparent material, which allows the attendant to know immediately whether the reel should be recharged or not.

Le caisson est articulé en partie basse par un axe 7 sur les flasques 6d de façon à pouvoir pivoter vers l'avant, comme l'illustre la figure 1. Une tige 8 relie ses parois latérales 5b et 5c et traverse des lumières (9) en forme de boutonnières circulaires ménagées dans les flasques. Ces lumières 9 et la tige 8 font fonction de moyens d'arrêt angulaire limitant le pivotement du caisson 5 par rapport à la plaque arrière. Les lumières 9 ont une longueur adaptée pour permettre un pivotement du caisson d'un angle de l'ordre de 20°, ce qui permet de charger aisément le magasin 3 dans la position ouverte.The box is articulated in the lower part by an axis 7 on the flanges 6d so as to be able to pivot forwards, as illustrated in FIG. 1. A rod 8 connects its side walls 5b and 5c and passes through slots (9) in the form of circular buttonholes formed in the flanges. These lights 9 and the rod 8 act as angular stop means limiting the pivoting of the box 5 relative to the rear plate. The lights 9 have a length adapted to allow pivoting of the box by an angle of the order of 20 °, which makes it possible to easily load the magazine 3 in the open position.

Par ailleurs, à sa partie haute, la paroi frontale 5a du caisson comporte une ouverture de passage S ayant la forme d'une fente rectangulaire s'étendant immédiatement au-dessous de la paroi supérieure 5d du boîtier, sur toute la largeur de la paroi frontale 5a. Cette fente est située dans un plan ascendant, c'est-à-dire dans un plan vertical ou incliné jusqu'à 30° environ par rapport à la verticale.Furthermore, at its upper part, the front wall 5a of the box has a passage opening S having the shape of a rectangular slot extending immediately below the upper wall 5d of the housing, over the entire width of the wall frontal 5a. This slot is located in an ascending plane, that is to say in a vertical plane or inclined up to approximately 30 ° relative to the vertical.

Les moyens de distribution de la bande sont décrits ci-après en supposant le boîtier fermé, de façon à permettre de préciser la position des organes par rapport à l'ouverture de passage S.The means of distributing the strip are described below, assuming the housing is closed, so as to make it possible to specify the position of the members with respect to the passage opening S.

Une paroi de guidage 10 est assujettie entre les flasques 6b solidaires de la paroi arrière 6 et est associée, à l'arrière, à des moyens de guidage de la bande, constitués en l'exemple par un tube 11 fixé entre les flasques ; ce tube de guidage est agencé en regard de la plaque arrière 6 pour délimiter un espace P de cheminement de la bande entre le magasin 3 et les moyens de distribution 2.A guide wall 10 is secured between the flanges 6b secured to the rear wall 6 and is associated, at the rear, with means for guiding the strip, constituted in the example by a tube 11 fixed between the flanges; this guide tube is arranged opposite the rear plate 6 to delimit a space P for routing the strip between the magazine 3 and the distribution means 2.

La paroi de guidage 10 comporte une zone interne 10a sensiblement horizontale, un seuil 10b situé au voisinage de l'ouverture S à proximité du bord inférieur de celle-ci et, à l'avant, une lèvre 10c s'étendant vers le bas au-delà de ce seuil. La lèvre 10c porte une douille taraudée 22 appelée à recevoir un organe inviolable 12 de fixation de la paroi frontale 5a sur la lèvre 10c. En l'exemple, la paroi 5a comporte un trou 13 à bord fraisé, qui débouche en regard de la douille 22 ; l'organe de fixation 12 est constitué par une vis qui possède une tête tronconique, logée dans la fraisure du trou 13 ; un évidement pratiqué dans la tête de vis permet de manoeuvrer cette dernière avec une clé spéciale 15.The guide wall 10 has a substantially horizontal internal zone 10a, a threshold 10b located in the vicinity of the opening S near the lower edge thereof and, at the front, a lip 10c extending downwards. beyond this threshold. The lip 10c carries a threaded socket 22 called to receive a tamper-evident member 12 for fixing the front wall 5a to the lip 10c. In the example, the wall 5a has a hole 13 with a milled edge, which opens facing the socket 22; the fixing member 12 is constituted by a screw which has a frustoconical head, housed in the countersink of the hole 13; a recess made in the screw head makes it possible to maneuver the latter with a special key 15.

Entre les flasques 6b, sont articulées trois ailes ; une aile de coupe 16, une première aile auxiliaire 17 et une seconde aile auxiliaire 18 ; ces ailes s'étendent d'un flasque à l'autre, sensiblement (au jeu près) sur toute la largeur du caisson 5 et de son ouverture S, de façon à obturer cette dernière.Between the flanges 6b, three wings are articulated; a cutting wing 16, a first auxiliary wing 17 and a second auxiliary wing 18; these wings extend from one flange to the other, substantially (apart from play) over the entire width of the box 5 and its opening S, so as to close the latter.

L'aile de coupe 16 est articulée autour d'un axe transversal X au moyen de deux tétons cylindriques qu'elle comporte de part et d'autre de son arête supérieure. (Par le terme « transversal •, on entend dans la présente demande une direction s'étendant dans le sens de la largeur - I - du caisson).The cutting wing 16 is articulated around a transverse axis X by means of two cylindrical pins which it comprises on either side of its upper edge. (By the term "transverse" in the present application is meant a direction extending in the direction of the width - I - of the box).

L'axe X d'articulation de l'aile de coupe 16 est situé au voisinage et au-dessous du bord supérieur de l'ouverture S, à l'opposé du seuil 10b de la paroi de guidage 10.The axis X of articulation of the cutting wing 16 is located in the vicinity and below the upper edge of the opening S, opposite the threshold 10b of the guide wall 10.

L'aile de coupe 16 est sensiblement plane et porte le long de son arête inférieure une découpe 16a en forme de dents de scie, destinée à jouer le rôle de moyens tranchants.The cutting wing 16 is substantially planar and carries along its lower edge a cutout 16a in the shape of a sawtooth, intended to play the role of cutting means.

L'aile de coupe peut pivoter autour de l'axe X depuis une position naturelle de repos dans laquelle elle vient reposer contre la seconde aile auxiliaire 18 par l'effet de son poids et une position de coupe dans laquelle elle vient en appui contre la première aile auxiliaire 17. Dans la position de repos, l'aile de coupe 16 se trouve située au voisinage du plan de l'ouverture S, tandis que, dans la position de coupe, elle vient en saillie en regard et à l'extérieur de ladite ouverture.The cutting wing can pivot around the X axis from a natural rest position in which it comes to rest against the second auxiliary wing 18 by the effect of its weight and a cutting position in which it comes to bear against the first auxiliary wing 17. In the rest position, the cutting wing 16 is located in the vicinity of the plane of the opening S, while, in the cutting position, it projects opposite and outside of said opening.

La première aile auxiliaire 17 est articulée autour d'un axe Y qui en l'exemple est commun avec l'axe d'articulation autour duquel pivote la seconde aile auxiliaire 18. Cet axe est formé par une tige cylindrique transversale portée de part et d'autre par les flasques 6b. La première aile 17 est fixée sur cette tige au moyen de deux pattes 19, cependant que la seconde aile 18 est articulée autour de ladite tige au moyen de petites chapes latérales 20 dotées de trous appropriés.The first auxiliary wing 17 is articulated around an axis Y which in the example is common with the articulation axis around which the second auxiliary wing 18 pivots. This axis is formed by a transverse cylindrical rod carried on either side other by the flanges 6b. The first wing 17 is fixed to this rod by means of two lugs 19, while the second wing 18 is articulated around said rod by means of small lateral yokes 20 provided with suitable holes.

L'axe Y d'articulation de ces ailes 17 et 18 est décalé par rapport à l'axe X et est situé au-dessus et au voisinage de la paroi de guidage 10, à l'arrière et à proximité du seuil 10b.The axis Y of articulation of these wings 17 and 18 is offset from the axis X and is located above and in the vicinity of the guide wall 10, at the rear and near the threshold 10b.

La première aile auxiliaire possède essentiellement trois portions : une portion de recouvrement 17a qui s'étend d'un côté de son articulation Y vers l'intérieur du boîtier au contact de la zone interne 10a, une portion de butée 17b, située de l'autre côté de l'articulation Y et qui s'étend, à l'opposé du seuil 10b, au voisinage du bord supérieur de l'ouverture S entre ce bord et l'axe X, enfin une portion ascendante 17c de jonction entre la portion 17b et la portion 17a.The first auxiliary wing has essentially three portions: a covering portion 17a which extends from one side of its articulation Y towards the interior of the housing in contact with the internal zone 10a, a stop portion 17b, located from the other side of the joint Y and which extends, opposite the threshold 10b, in the vicinity of the upper edge of the opening S between this edge and the axis X, finally an ascending portion 17c of junction between the portion 17b and portion 17a.

La portion de butée 17b forme, en direction de l'ouverture S, une avancée située au-dessus de l'aile de coupe 16 de sorte que cette dernière vienne en appui contre celle-ci lorsqu'elle parvient en position de coupe. En l'exemple, la portion de butée 17b se prolonge par un retour 17d orienté vers le haut afin d'obturer entièrement l'ouverture S.The abutment portion 17b forms, in the direction of the opening S, a projection situated above the cutting wing 16 so that the latter comes to bear against the latter when it reaches the cutting position. In the example, the abutment portion 17b is extended by a return 17d oriented upwards in order to completely close the opening S.

La portion de jonction 17c (portion ascendente) est située à l'arrière de l'aile de coupe 16 et est reliée à la portion de butée 17b par un coude situé au-dessus et à l'arrière de l'axe X.The junction portion 17c (ascending portion) is located at the rear of the cutting wing 16 and is connected to the abutment portion 17b by an elbow located above and behind the X axis.

La portion de recouvrement 17a épouse la forme de la zone interne 10a de façon à délimiter un chemin C de passage pour la bande, au niveau duquel celle-ci est freinée par la friction exercée par cette portion 17a ; cette portion 17a possède un prolongement lesté 17e qui s'écarte de la paroi 10a en vue, d'une part, de donner une forme évasée à l'entrée du chemin de passage C, d'autre part, de permettre un ajustement des forces de friction provoquées par l'appui de la portion 17a sous l'influence des forces de gravité.The covering portion 17a follows the shape of the internal zone 10a so as to delimit a path C of passage for the strip, at which the latter is braked by the friction exerted by this portion 17a; this portion 17a has a weighted extension 17e which departs from the wall 10a in order, on the one hand, to give a flared shape at the entrance to the passageway C, on the other hand, to allow an adjustment of the forces friction caused by the support of the portion 17a under the influence of gravity forces.

Enfin, la seconde aile auxiliaire 18 présente, en section transversale, une hauteur appropriée pour venir reposer sur le seuil 10b sous l'effet de son poids (la hauteur d'une aile étant définie par la distance séparant son axe d'articulation et son bord extrême le plus éloigné) ; de plus, la hauteur de cette aile 18 est très inférieure à celle de l'aile de coupe 16.Finally, the second auxiliary wing 18 has, in cross section, a height suitable for coming to rest on the threshold 10b under the effect of its weight (the height of a wing being defined by the distance separating its axis of articulation and its most distant end edge); moreover, the height of this wing 18 is much less than that of the cutting wing 16.

En outre, cette aile 18 possède une portion de protection (18a) en forme d'un retour qui la prolonge vers le haut et vers l'arrière par l'entremise d'un bord coudé 18b. Ce retour présente une direction angulaire telle qu'il vienne s'accoler avec l'aile de coupe dans la position naturelle de repos, le plan dudit retour et celui de l'aile 16 coïncidant sensiblement au repos (aux épaisseurs de matière près).In addition, this wing 18 has a protective portion (18a) in the form of a return which extends it upwards and backwards via a bent edge 18b. This return has an angular direction such that it comes to join with the cutting wing in the natural position of rest, the plane of said return and that of the wing 16 coinciding substantially at rest (except for thicknesses of material).

De plus, l'aile de coupe 16 présente, en section transversale, une hauteur inférieure à la distance séparant, en position naturelle de repos, le bord 18b de l'aile 18 et l'axe d'articulation X de l'aile de coupe.In addition, the cutting wing 16 has, in cross section, a height less than the distance separating, in the natural position of rest, the edge 18b of the wing 18 and the axis of articulation X of the wing of chopped off.

Ainsi, en position de repos, l'aile de coupe 16 repose contre le retour 18a de l'aile 18 sans déborder de ladite aile, ses moyens tranchants 16a étant accolés contre le retour et s'effaçant, dans un état inoffensif, contre la face supérieure de ce retour.Thus, in the rest position, the cutting wing 16 rests against the return 18a of the wing 18 without protruding from said wing, its cutting means 16a being contiguous against the return and disappearing, in a harmless state, against the upper side of this return.

Par ailleurs, la figure 4 montre une bande 4 conforme à l'invention ; cette bande est formée par une longueur continue de papier (ou autre matériau à couper), qui est conditionné à l'état replié en accordéon ; comme le montre la figure 5, les différents plis sont sensiblement superposés dans deux plans parallèles, de façon à conférer à la bande la forme d'un parallélépipède rectangle. Une fois la bande chargée dans le dévidoir, ces plans viennent se situer à proximité respectivement de la plaque arrière 6 et de la paroi frontale 5a.Furthermore, Figure 4 shows a strip 4 according to the invention; this strip is formed by a continuous length of paper (or other material to be cut), which is packaged in an accordion folded state; as shown in Figure 5, the different folds are substantially superimposed in two parallel planes, so as to give the strip the shape of a rectangular parallelepiped. Once the strip is loaded in the reel, these planes are located in the vicinity of the rear plate 6 and of the front wall 5a respectively.

Un conditionnement périphérique 21, constitué en l'exemple par une enveloppe en matière synthétique souple transparente, maintient la bande en forme pendant les transports et stockages et évite son dépliage.A peripheral packaging 21, constituted in the example by a transparent flexible plastic envelope, keeps the strip in shape during transport and storage and prevents its unfolding.

Lors du chargement, cette enveloppe est déchirée en partie haute, la bande est installée dans le magasin du dévidoir et son extrémité est repoussée dans le chemin de passage C (grâce à un léger pivotement de l'aile 17) jusqu'à sortir entre l'aile auxiliaire 18 et le seuil 10b. Le caisson 5 peut alors être refermé et verrouillé : le dévidoir est prêt à l'emploi.During loading, this envelope is torn in the upper part, the strip is installed in the reel magazine and its end is pushed back into the passageway C (thanks to a slight pivoting of the wing 17) until it exits between the auxiliary wing 18 and the threshold 10b. The box 5 can then be closed and locked: the reel is ready for use.

Les figures 6a, 6b, 6c et 6d illustrent le fonctionnement de celui-ci.Figures 6a, 6b, 6c and 6d illustrate the operation thereof.

La figure 6a montre les moyens de distribution au repos. La bande passe entre la seconde aile auxiliaire 18 et le seuil 10b et dépasse à l'extérieur du dévidoir. L'aile de coupe 16a repose contre le retour 18a sans risque pour les utilisateurs.Figure 6a shows the distribution means at rest. The strip passes between the second auxiliary wing 18 and the threshold 10b and protrudes outside the reel. The cutting wing 16a rests against the return 18a without risk for the users.

La figure 6b schématise la phase de distribution de bande : l'utilisateur exerce une traction continue modérée T sur l'extrémité de la bande ; celle-ci est freinée par la première aile auxiliaire 17 et est distribuée de façon régulière sans risque de déchirement ni de gaspillage. Selon la direction de la traction T, l'aile 18 demeure en place ou se soulève légèrement.FIG. 6b shows diagrammatically the strip distribution phase: the user exerts a moderate continuous traction T on the end of the strip; it is braked by the first auxiliary wing 17 and is distributed regularly without the risk of tearing or waste. Depending on the direction of traction T, the wing 18 remains in place or lifts slightly.

La figure 6c illustre une position intermédiaire des moyens de distribution lorsque l'opérateur commence à exercer une traction vers le haut sur la bande avant d'atteindre la position de coupe. L'aile 18 s'efface progressivement derrière l'aile de coupe jusqu'à ce que la bande vienne au contact des moyens tranchants 16a, lesquels viennent alors se disposer en saillie à l'avant de l'ouverture S.FIG. 6c illustrates an intermediate position of the dispensing means when the operator begins to exert an upward pull on the strip before reaching the cutting position. The wing 18 gradually disappears behind the cutting wing until the strip comes into contact with the cutting means 16a, which then come to protrude at the front of the opening S.

Enfin, la figure 6d illustre la position de coupe : l'utilisateur exerce une brusque traction de rupture vers le haut R ; l'aile de coupe 16, en butée contre la première aile auxiliaire 17, transmet à celle-ci un moment M qui se traduit par l'apparition d'un effort de blocage B au niveau de la portion de recouvrement 17a. La bande est bloquée à ce niveau et la traction R provoque la coupure nette et franche de la bande au contact des moyens tranchants.Finally, FIG. 6d illustrates the cutting position: the user exerts an abrupt upward tensile strength R; the cutting wing 16, in abutment against the first auxiliary wing 17, transmits a moment M to the latter, which results in the appearance of a locking force B at the level of the covering portion 17a. The strip is blocked at this level and the traction R causes the clean and frank cut of the strip in contact with the cutting means.

Il est à noter qu'une longueur de dépassement - b - est préservée à l'extrémité de la bande, cette longueur permettant une préhension facile lors de la distribution suivante. En outre, la présence des trois ailes et leur agencement écartent les risques de désamorçage de la bande, en empêchant que le papier puisse être repoussé vers l'intérieur, volontairement ou involontairement.It should be noted that an overhang length - b - is preserved at the end of the strip, this length allowing easy gripping during the next distribution. In addition, the presence of the three wings and their arrangement eliminate the risks of defusing the strip, by preventing the paper from being able to be pushed back inwards, voluntarily or involuntarily.

Le dévidoir décrit ci-dessus à titre d'exemple comporte son propre boîtier ; il est possible, en variante dans certaines applications, que le boîtier du dévidoir soit constitué par un logement ménagé dans une structure déjà existante (notamment sur les véhicules ou aéronefs).The reel described above by way of example has its own housing; it is possible, as a variant in certain applications, that the housing of the reel is constituted by a housing formed in an already existing structure (in particular on vehicles or aircraft).
