Description

Roue à nez monomatière avec bandage recyclable, destinée notamment aux poubelles collectives. Single-component nose wheel with recyclable tire, especially intended for collective trash cans.
La présente invention concerne une roue à nez, monomatière, munie d'un bandage, destinée notamment pour les poubelles collectives de type à deux roues.The present invention relates to a nose wheel, single-material, provided with a tire, intended in particular for collective bins of the two-wheel type.
La plupart des communes et des villes imposent de plus en plus l'usage de collecteurs d'ordures sur roues, munies de moyens d'accrochage venant coopérer conjointement avec le dispositif de levage et de basculement des véhicules de ramassage équipés à cet effet.Most municipalities and cities are increasingly imposing the use of garbage collectors on wheels, fitted with hooking means which cooperate jointly with the lifting and tilting device of the collection vehicles equipped for this purpose.
Les roues utilisées actuellement pour ces poubelles sont, en principe, des roues de type à nez fixées de part et d'autre de ladite poubelle, sur un axe de support comportant, à chaque extrémité, une gorge. La fixation de ces roues sur ledit axe se fait respectivement au moyen d'un loqueteau métallique et d'un ressort à travers un trou prévu à cet effet dans le moyeu de ladite roue et venant s'adapter dans ladite gorge. L'ensemble, loqueteau et ressort métalliques sont maintenus en place dans ladite gorge au moyen d'un bandage pneumatique adapté dans la jante et venant alors s'appuyer sur ledit ressort.The wheels currently used for these bins are, in principle, nose type wheels fixed on either side of said bin, on a support pin having, at each end, a groove. The fixing of these wheels on said axle is done respectively by means of a metal catch and a spring through a hole provided for this purpose in the hub of said wheel and coming to fit in said groove. The assembly, latch and metal spring are held in place in said groove by means of a pneumatic tire adapted in the rim and then coming to bear on said spring.
Ces roues sont généralement équipées de pneumatiques pleins. Par ailleurs, les jantes de ces roues comportent le plus souvent, sur leurs faces intérieure et/ou extérieure, des rayons et moulures apparents qui retiennent les boues et les salissures. Devant les problèmes actuels concernant la pollution d'une part, et l'encombrement des objets usagés et des déchets d'autre part, ainsi que les problèmes économiques pour traiter ces déchets, il est nécessaire de concevoir les objets, conteneurs ou autres en matériaux recyclables et peu coûteux. Des roues comme ci-dessus désignées qui comportent des parties caoutchouteuses d'une part, et des parties métalliques d'autre part, ne peuvent pas être recyclées en l'état.These wheels are generally fitted with solid tires. Furthermore, the rims of these wheels most often have, on their inner and / or outer faces, spokes and visible moldings which retain the sludge and dirt. Faced with the current problems concerning pollution on the one hand, and the size of used objects and waste on the other hand, as well as the economic problems to treat this waste, it is necessary to design objects, containers or other materials recyclable and inexpensive. Wheels as above designated which have rubber parts on the one hand, and metal parts on the other hand, cannot be recycled as is.
Le recyclage de telles roues est très coûteux, puisqu'il nécessite au préalable, le démontage du pneumatique fixe par destination, d'une part, pour libérer le ressort et le loqueteau métalliques, et, d'autre part, permettre enfin, la dépose de l'axe métallique. EP-A-0 508 902 représente l'état de la technique le plus proche de la présente invention, car il concerne une roue de type à nez qui comporte un moyeu se prolongeant axialement, d'un côté de la roue, par un fourreau tubulaire rigide destiné à recevoir l'axe de support d'un récipient servant notamment à la collecte de déchets, une jante périphérique destinée à recevoir un bandage de roulement, un voile de liaison s'étendant radialement et reliant le moyeu à la jante, et un dispositif de blocage muni d'un loqueteau de verrouillage susceptible de s'engager radialement dans une gorge annulaire d'une partie extrême de l'axe de support, lorsque celle-ci est introduite dans ledit moyeu.The recycling of such wheels is very expensive, since it requires beforehand, the dismantling of the fixed tire by destination, on the one hand, to release the metal spring and latch, and, on the other hand, finally allow the removal of the metal axis. EP-A-0 508 902 represents the state of the art closest to the present invention, since it relates to a nose type wheel which has a hub extending axially, on one side of the wheel, by a sheath rigid tubular intended to receive the support axis of a container used in particular for collecting waste, a peripheral rim intended to receive a tread, a connecting web extending radially and connecting the hub to the rim, and a locking device provided with a locking latch capable of engaging radially in an annular groove of an end part of the support axis, when the latter is introduced into said hub.
Partant de cet état de la technique, la présente invention propose une roulette à nez qui soit facile à recycler.Based on this state of the art, the present invention provides a nose wheel which is easy to recycle.
L'invention atteint son but par le fait que tous les éléments constitutifs de la roue, y compris le bandage et le dispositif de blocage, sont réalisés par moulage sous pression d'une matière plastique recyclable et, à l'exception du bandage, sont moulés d'une seule pièce prête à l'usage.The invention achieves its object by the fact that all the constituent elements of the wheel, including the tire and the locking device, are produced by die-casting of a recyclable plastic material and, with the exception of the tire, are molded in one piece ready for use.
La roue sans le bandage peut être réalisée par exemple par moulage sous pression de polyéthylène haute densité, et le bandage en polyéthylène basse densité linéaire.The wheel without the bandage can be produced for example by die-casting of high density polyethylene, and the bandage in linear low density polyethylene.
Avantageusement, le loqueteau de verrouillage est constitué par au moins une languette qui s'étend parallèlement à l'axe de la roue à l'intérieur du moyeu et qui est munie à son extrémité libre d'un téton de verrouillage pénétrant dans la gorge annulaire de l'axe de support, ladite languette se raccordant par son autre extrémité au moyeu ou au fourreau de prolongement de celui-ci et formant, par sa face intérieure, un appui périphérique pour l'axe de support.Advantageously, the locking latch is constituted by at least one tongue which extends parallel to the axis of the wheel inside the hub and which is provided at its free end with a locking pin penetrating into the annular groove of the support axis, said tab being connected by its other end to the hub or to the extension sleeve thereof and forming, by its inner face, a peripheral support for the support axis.
De préférence, le voile de liaison comprend deux flasques radiaux en forme de coupelles à fond plat, dont au moins celui situé du côté du fourreau de prolongement est solidaire de celui-ci, lesdits flasques étant reliés l'un à l'autre par des entretoises qui s'étendent soit dans un plan radial, soit dans des plans parallèles à un plan radial de ladite roue, les faces extrêmes internes desdites entretoises étant solidaires du moyeu ou formant des faces d'appui pour l'axe de support, tandis que leurs faces extrêmes externes forment des faces d'appui pour le bandage en même temps que les faces externes des parties périphériques de chaque flasque, lesdites parties périphériques étant évasées vers l'extérieur.Preferably, the connecting veil comprises two radial flanges in the form of flat-bottomed cups, at least one of which located on the side of the extension sleeve is integral with the latter, said flanges being connected to one another by spacers which extend either in a radial plane or in planes parallel to a radial plane of said wheel, the internal end faces of said spacers being integral with the hub or forming bearing faces for the support axis, while their outer end faces form bearing faces for the bandage at the same time as the outer faces of the parts peripherals of each flange, said peripheral parts being flared outwards.
Selon un mode de réalisation particulier, la languette est disposée entre deux entretoises voisines à un plan radial de la roue. La roue comporte quatre languettes espacées angulairement de 90* autour de l'axe de rotation, ainsi que quatre entretoises supplémentaires situées dans des plans radiaux, bissecteurs des plan radiaux médians des languettes. Ces entretoises supplémentaires présentent une épaisseur circonférentielle qui s'agrandit au voisinage des faces extrêmes externes, afin d'augmenter la surface d'appui du bandage sur la jante. Le flasque situé du côté opposé au fourreau de prolongement est plein et ce flasque présente dans sa partie centrale un bulbe susceptible de coopérer avec l'extrémité libre du fourreau de prolongement d'une deuxième roue pour faciliter la palettisation desdites roues. La partie extrême de l'axe de support loge à l'intérieur du bulbe, et le téton de verrouillage est disposé du côté du flasque plein par rapport au plan médian de la roue.According to a particular embodiment, the tongue is disposed between two spacers adjacent to a radial plane of the wheel. The wheel comprises four tongues spaced angularly by 90 * around the axis of rotation, as well as four additional spacers located in radial planes, bisectors of the median radial plane of the tongues. These additional spacers have a circumferential thickness which increases in the vicinity of the outer end faces, in order to increase the bearing surface of the tire on the rim. The flange located on the side opposite the extension sheath is full and this flange has in its central part a bulb capable of cooperating with the free end of the extension sheath of a second wheel to facilitate the palletization of said wheels. The extreme part of the support axis is housed inside the bulb, and the locking pin is arranged on the side of the full flange relative to the median plane of the wheel.
Dans une première forme d'application, la roue monomatière selon l'invention pourra s'adapter sur un axe métallique au moyen des tétons des languettes directement adaptables dans la gorge dudit axe par clipsage.In a first form of application, the single-material wheel according to the invention can be adapted on a metal axis by means of the pins of the tongues directly adaptable in the groove of said axis by clipping.
Dans une deuxième forme d'application, l'axe de support sera partie intégrante du conteneur et réalisé en même temps que lui, dans un moule approprié par coulée d'une matière recyclable telle que du polyéthylène haute densité. Pour éviter la retenue des salissures la jante de la roue selon l'invention est formée de part et d'autre, de flasques plats, facilitant ainsi le nettoyage, la structure en forme de rayons des entretoises se trouvant enfermée à l'intérieur de la jante, entre ces deux flasques et le bandage.In a second form of application, the support axis will be an integral part of the container and produced at the same time as it, in a suitable mold by casting a recyclable material such as high density polyethylene. To prevent dirt from being retained, the rim of the wheel according to the invention is formed on either side of flat flanges, thereby facilitating cleaning, the spoke-like structure of the spacers being enclosed inside the rim, between these two flanges and the bandage.

La roue à nez telle que représentée en coupe sur les figures 1 et 11 comporte une jante périphérique 1, au centre un moyeu 4 et des flasques plats 2 et 3 radiaux reliant la jante 1 au moyeu 4. A l'intérieur du moyeu 4 se trouvent des clips 5 venant s'adapter dans la gorge 6 d'un axe 7. Lesdits clips 5 sont rendus élastiques à travers une lumière 8, des jambes de force 9 de forme et dimensions appropriées permettent de durcir le ressort desdits clips 5 en fonction de la résistance désirée.The nose wheel as shown in section in FIGS. 1 and 11 has a peripheral rim 1, in the center a hub 4 and flat flanges 2 and 3 connecting the rim 1 to the hub 4. Inside the hub 4 is find clips 5 coming to fit in the groove 6 of an axis 7. Said clips 5 are made elastic through a hole 8, struts 9 of suitable shape and dimensions allow the spring of said clips 5 to harden in function of the desired resistance.
Le moyeu 4 est prolongé axialement d'un côté de la roue par un fourreau 20 tubulaire rigide.The hub 4 is extended axially on one side of the wheel by a rigid tubular sheath 20.
Les deux flasques radiaux 2 et 3 se présentent sous la forme de coupelles à fond plat dont les rebords périphériques 21, 22 sont évasés vers l'extérieur et constituent les bords de la jante 1.The two radial flanges 2 and 3 are in the form of flat-bottomed cups, the peripheral edges 21, 22 of which are flared outwards and constitute the edges of the rim 1.
Le flasque 3 situé du côté du fourreau de prolongement 20 est solidaire de ce dernier. L'autre flasque 2 est également solidaire du moyeu 4 dans sa partie centrale, mais il bouche l'extrémité du moyeu 4, afin d'éviter l'introduction des saletés à l'intérieur du moyeu 4.The flange 3 located on the side of the extension sheath 20 is integral with the latter. The other flange 2 is also secured to the hub 4 in its central part, but it plugs the end of the hub 4, in order to avoid the introduction of dirt inside the hub 4.
La figure 2 représente une extrémité d'un axe métallique 7 munie d'une gorge 6 destinée à recevoir les clips 5 à l'intérieur du moyeu 4 de la roue et une partie conique 10 permettant l'introduction dudit axe 7 entre les clips 5.FIG. 2 represents an end of a metal axis 7 provided with a groove 6 intended to receive the clips 5 inside the hub 4 of the wheel and a conical part 10 allowing the introduction of said axis 7 between the clips 5 .
La figure 3 représente en détail un clip 5 à l'intérieur du moyeu 4, ledit clip 5 est entouré d'une lumière 8 en forme de U permettant l'élasticité pour son positionnement à l'intérieur de la gorge 6 de l'axe 7. Le clip 5 est formé par une languette qui s'étend parallèlement à l'axe 23 de rotation de la roue à l'intérieur du moyeu 4, et qui est munie à son extrémité libre d'un téton de verrouillage 24 qui pénètre dans la gorge annulaire 6 de l'axe de support 7. La languette se raccorde par son autre extrémité 25 au moyeu 4 ou au fourreau 20 de prolongement du moyeu 4 et forme par sa face intérieure un appui périphérique pour l'axe de support 7.Figure 3 shows in detail a clip 5 inside the hub 4, said clip 5 is surrounded by a light 8 in a U shape allowing the elasticity for its positioning inside the groove 6 of the axis 7. The clip 5 is formed by a tongue which extends parallel to the axis 23 of rotation of the wheel inside the hub 4, and which is provided at its free end with a locking pin 24 which penetrates in the annular groove 6 of the support axis 7. The tongue is connected by its other end 25 to the hub 4 or to the sleeve 20 for extension of the hub 4 and forms by its inner face a peripheral support for the support axis 7 .
La vue de la roue présentée sur la figure 4 montre la structure intérieure de la jante 1 faisant apparaître les différents couloirs 11 pour le démoulage de ladite roue. La coupe transversale de la jante 1 de la roue représentée sur les figures 5 et 12 montre en détail la structure intérieure de ladite roue.The view of the wheel presented in FIG. 4 shows the internal structure of the rim 1 showing the various lanes 11 for demolding said wheel. The cross section of the rim 1 of the wheel shown in Figures 5 and 12 shows in detail the interior structure of said wheel.
Cette structure comporte essentiellement une pluralité d'entretoises 26 qui relient les deux flasques 2 et 3 depuis le moyeu 4 jusqu'au bandage 12. Les entretoises 26 s'étendent dans des plans radiaux passant par l'axe de rotation 23 de la roue ou dans des plans parallèles à un plan radial de la roue. Les faces extrêmes intérieures 27 des entretoises 26 sont soit solidaires du moyeu 4, comme on le voit sur la figure 5, soit forment les faces d'appui pour l'axe de support 7 comme on le voit sur la figure 12. Leurs faces extrêmes 28 forment des faces d'appui pour le bandage 12 en même temps que les rebords périphériques 21, 22 des flasques 2 et 3. Comme on le voit sur les figures 5 et 12, les languettes constituant les clips 5 sont disposées dans le moyeu 4 entre deux entretoises parallèles 26a, 26b voisines, et le moyeu 4 est muni de quatre languettes espacées angulairement de 90* autour de l'axe de rotation 23. Dans les plans bissecteurs des plans radiaux passant par les languettes 5 sont disposées quatre entretoises 26c. Ces entretoises 26c présentent une surépaisseur 29 au voisinage de leurs faces externes 28, afin d'augmenter la surface d'appui du bandage 12. Comme on le voit clairement sur les figures 1 et 11, les faces extrêmes extérieures 28 et les faces extérieures des rebords périphériques 21, 22 des flasques 2 et 3 se raccordent entre elles, afin de constituer une gouttière pour loger le bandage 12, cette partie extérieure constituant la jante proprement dite de la roue. La vue de la roue représentée sur la figure 6 montre en détail le moyeu 4 de la roue faisant apparaître les tétons de verrouillage 24 et leur emplacement à l'intérieur dudit moyeu 4.This structure essentially comprises a plurality of spacers 26 which connect the two flanges 2 and 3 from the hub 4 to the tire 12. The spacers 26 extend in radial planes passing through the axis of rotation 23 of the wheel or in planes parallel to a radial plane of the wheel. The inner end faces 27 of the spacers 26 are either integral with the hub 4, as seen in Figure 5, or form the bearing faces for the support axis 7 as seen in Figure 12. Their end faces 28 form bearing faces for the tire 12 at the same time as the peripheral edges 21, 22 of the flanges 2 and 3. As can be seen in FIGS. 5 and 12, the tongues constituting the clips 5 are arranged in the hub 4 between two adjacent parallel struts 26a, 26b, and the hub 4 is provided with four tongues spaced angularly by 90 * around the axis of rotation 23. In the bisector planes of the radial planes passing through the tongues 5 are arranged four spacers 26c. These spacers 26c have an extra thickness 29 in the vicinity of their external faces 28, in order to increase the bearing surface of the tire 12. As can clearly be seen in FIGS. 1 and 11, the external extreme faces 28 and the external faces of the peripheral edges 21, 22 of the flanges 2 and 3 are connected together, in order to constitute a gutter for housing the tire 12, this external part constituting the actual rim of the wheel. The view of the wheel shown in FIG. 6 shows in detail the hub 4 of the wheel showing the locking pins 24 and their location inside said hub 4.
Le figure 7 représente un bandage 12 comportant des parties pleines 13 exécutés en polyéthylène basse densité linéaire et des parties creuses 14 contenant du gaz sous pression obtenu par le procédé "AIR- MOLD".FIG. 7 represents a tire 12 comprising solid parts 13 made of linear low density polyethylene and hollow parts 14 containing gas under pressure obtained by the "AIR-MOLD" process.
La figure 8 représente une coupe du bandage 12 selon la figure 7 montrant la cavité creuse 14 dudit bandage 12 contenant le gaz sous pression. La figure 9 représente la partie basse d'une poubelle du type à deux roues, équipée d'une paire de roues selon une première forme d'application de l'invention, ladite figure présentant un schéma d'adaptation desdites roues sur un axe métallique 7.FIG. 8 represents a section of the bandage 12 according to FIG. 7 showing the hollow cavity 14 of said bandage 12 containing the gas under pressure. FIG. 9 represents the lower part of a bin of the two-wheel type, equipped with a pair of wheels according to a first form of application of the invention, said figure presenting a diagram of adaptation of said wheels on a metal axis 7.
La figure 10 représente, selon une deuxième forme d'application, une roue selon l'invention adaptée sur un axe 15 en polyéthylène haute densité, monobloc avec le récipient collecteur, ladite figure montrant en schéma, l'adaptation d'une telle roue sur un tel axe, notamment les clipsFIG. 10 represents, according to a second form of application, a wheel according to the invention adapted on an axis 15 made of high density polyethylene, in one piece with the collecting container, said figure showing in diagram, the adaptation of such a wheel on such an axis, including clips
5 du moyeu 4 de la roue, venant s'adapter dans la gorge 16 de l'axe 15.5 of the hub 4 of the wheel, fitting into the groove 16 of the axle 15.
Dans une forme préférentielle d'application, la roue à nez selon l'invention comporte une jante 1 monomatière recyclable telle que du polyéthylène haute densité comprenant de part et d'autre des flasques plats 2 et 3, et au centre un moyeu 4 destiné à être adapté sur un axe de support 7, la fixation sur ledit axe 7 se faisant au moyen de pattes de clipsage 5 prévues à cet effet à l'intérieur dudit moyeu 4 et venant s'adapter dans la gorge 6 dudit axe 7, ladite roue étant munie d'un bandage 12 en matière recyclable telle que du polyéthylène basse densité linéaire, de forme et de dimensions appropriées pour pouvoir être adaptée sur la jante 1.In a preferred form of application, the nose wheel according to the invention comprises a rim 1 recyclable single material such as high density polyethylene comprising on both sides of the flat flanges 2 and 3, and in the center a hub 4 intended to be adapted on a support axis 7, the fixing on said axis 7 being done by means of clipping lugs 5 provided for this purpose inside said hub 4 and coming to fit in the groove 6 of said axis 7, said wheel being provided with a bandage 12 of recyclable material such as low polyethylene linear density, of suitable shape and dimensions to be able to be adapted on rim 1.
Les deux flasques 2 et 3 ont la propriété d'éviter la retenue des salissures de la jante 1, et de faciliter le nettoyage, la structure en forme de rayons des entretoises 26 se trouvant enfermée à l'intérieur de ladite jante 1, entre lesdits flasques 2 et 3 et le bandage 12. Le flasque 2, côté extérieur de la jante 1, est plein et lisse, le flasque 3, côté intérieur, est également lisse, et est traversé en son centre par le moyeu 4 de la roue de façon à recevoir l'axe 7. Les pattes de clipsage 5 sont rendues élastiques, du fait qu'elles s'étendent axialement dans la lumière 8 en forme de U. Des jambes de force 9, de forme et de dimensions appropriées en fonction de la résistance désirée, peuvent être prévues solidaires de la face extérieure du moyeu 4 et de la face intérieure du flasque intérieur 3. Les flasques 2 et 3 sont renforcés au moyen de la structure intérieure en étoile constituée par les entretoises 26. Ces entretoises 26 ont donc deux fonctions : d'une part, elles renforcent la roue 1 et, d'autre part, elles servent de surface d'appui, par leurs faces extrêmes extérieures 28, au bandage 12. Les espaces vides ou couloirs 11 en forme de coins disposés entre deux entretoises 26 voisines sont conformés de manière à permettre le démoulage de la roue par retrait de tiroirs appropriés.The two flanges 2 and 3 have the property of preventing the retention of dirt from the rim 1, and of facilitating cleaning, the spoke-like structure of the spacers 26 being enclosed inside said rim 1, between said rims flanges 2 and 3 and the tire 12. The flange 2, on the outside of the rim 1, is full and smooth, the flange 3, on the inside, is also smooth, and is crossed in its center by the hub 4 of the wheel. so as to receive the axis 7. The clipping tabs 5 are made elastic, because they extend axially in the lumen 8 in the form of a U. Struts 9, of suitable shape and dimensions depending on the desired resistance can be provided integral with the outer face of the hub 4 and the inner face of the inner flange 3. The flanges 2 and 3 are reinforced by means of the inner star structure constituted by the spacers 26. These spacers 26 have so two functions : on the one hand, they reinforce the wheel 1 and, on the other hand, they serve as a bearing surface, by their outer outer faces 28, for the tire 12. The empty spaces or corridors 11 in the form of corners arranged between two neighboring spacers 26 are shaped so as to allow the wheel to be removed from the mold by removing appropriate drawers.
La jante 1 de la roue est conçue de forme appropriée de manière à retenir en place un bandage 12, ledit bandage 12 comportant des parties pleines 13 réalisées en polyéthylène basse densité linéaire et des parties creuses 14 contenant du gaz sous pression obtenu par le procédé "AIR- MOLD".The rim 1 of the wheel is designed in an appropriate shape so as to retain a bandage 12 in place, said bandage 12 comprising solid parts 13 made of linear low density polyethylene and hollow parts 14 containing gas under pressure obtained by the process " AIR- MOLD ".
Afin de rendre le collecteur d'ordures entièrement recyclable sans aucune intervention de démontage, dans une autre forme d'application de l'invention, l'axe métallique 7 pourra être avantageusement remplacé par un axe 15 de part et d'autre dudit collecteur, réalisé en polyéthylène haute densité, monobloc avec ledit récipient collecteur, les clips 5 du moyeu 4 de la roue, venant s'adapter dans la gorge 16 dudit axe 15 prévue à cet effet. La roue à nez monomatière recyclable selon la présente invention est réalisée en matière plastique telle que du polyéthylène haute densité injecté sous pression dans un moule, les clips 5 destinés à la maintenir sur un axe faisant partie intégrante de la jante 1 étant prévus dans le moule à l'intérieur du moyeu 4.In order to make the garbage collector fully recyclable without any dismantling intervention, in another form of application of the invention, the metal axis 7 could advantageously be replaced by an axis 15 on either side of said collector, made of high density polyethylene, in one piece with said collecting container, the clips 5 of the hub 4 of the wheel, fitting into the groove 16 of said axis 15 provided for this purpose. The recyclable single-material nose wheel according to the present invention is made of plastic material such as high density polyethylene injected under pressure into a mold, the clips 5 intended to hold it on an axis forming an integral part of the rim 1 being provided in the mold inside the hub 4.
Après démoulage de la roue par retrait des tiroirs prévus à cet effet dans la structure intérieure de la jante 1, le bandage 12 est mis en place sur ladite jante 1 de forme appropriée, destinée à le recevoir.After demolding the wheel by removing the drawers provided for this purpose in the inner structure of the rim 1, the tire 12 is placed on said rim 1 of suitable shape, intended to receive it.
Les roues selon l'invention, munies de leur bandage 12 sont alors positionnées sur l'axe métallique 7 de part et d'autre de la poubelle collective de type à deux roues. Chaque extrémité en forme conique 10 de l'axe 7 est introduite à l'intérieur du moyeu 4, la roue étant maintenue en place au moyen des clips 5 venant s'adapter dans la gorge 6 dudit axe 7.The wheels according to the invention, provided with their tire 12 are then positioned on the metal axis 7 on either side of the collective bin of the two-wheel type. Each conical end 10 of the axis 7 is introduced inside the hub 4, the wheel being held in place by means of the clips 5 coming to fit in the groove 6 of the said axis 7.
Lors du recyclage, seule l'opération de dépose de la roue de l'axe métallique 7 est nécessaire, la roue elle-même et son bandage y compris les clips 5 indissociables de ladite roue étant entièrement recyclables.During recycling, only the operation of removing the wheel from the metal axle 7 is necessary, the wheel itself and its tire including the clips 5 inseparable from said wheel being entirely recyclable.
Dans la deuxième application de l'invention, la roue et son bandage 12 est fixée au moyen des clips 5 adaptées dans la gorge 16 d'un axe 15, ledit axe 15 faisait partie intégrante du récipient collecteur et réalisé en matière plastique telle que du polyéthylène haute densité, injecté sous pression dans le moule.In the second application of the invention, the wheel and its tire 12 is fixed by means of clips 5 adapted in the groove 16 of an axis 15, said axis 15 was an integral part of the collecting container and made of plastic such as high density polyethylene, injected under pressure into the mold.
Cette forme d'application de l'invention a l'avantage de permettre, de façon économique, le recyclage complet du récipient collecteur d'ordures et des roues munies de leur bandage 12, ledit recyclage ne nécessitant aucune opération de démontage.This form of application of the invention has the advantage of allowing, in an economical manner, the complete recycling of the refuse collection container and of the wheels provided with their tire 12, said recycling requiring no dismantling operation.
La roue à nez monomatière avec bandage recyclable est destinée aux poubelles collectives de type à deux roues, munies soit d'un axe métallique, soit d'un axe en matière plastique faisant corps avec ledit récipient collecteur. Les figures 11 et 12 montrent un mode préféré de réalisation de la roue selon l'invention, sans le bandage 12. La partie centrale du flasque extérieur 2 présente un bulbe 30 qui est dimensionné en fonction du diamètre intérieur du fourreau 20 de prolongement, afin de faciliter la palettisation des roues semblables. Deux roues peuvent être empilées l'une sur l'autre en plaçant le bulbe 30 d'une roue supérieure dans le fourreau 20 de prolongement d'une roue inférieure. De plus, grâce à cette disposition, la tête 31 de l'axe de support 7 peut loger à l'intérieur du bulbe 30. La gorge 6 de l'axe de support 7 et les tétons de verrouillage 24 sont ainsi rapprochés du flasque extérieur 2. Ceci améliore la tenue de la roue sur l'axe de support 7, du fait que les forces exercées sur la roue sont disposées dans le plan médian 32 de celle-ci, c'est-à-dire en dehors de la gorge 6.The single-material nose wheel with recyclable tire is intended for collective trash cans of the two-wheel type, provided either with a metal axle or with a plastic axle integral with said collecting container. Figures 11 and 12 show a preferred embodiment of the wheel according to the invention, without the tire 12. The central part of the outer flange 2 has a bulb 30 which is dimensioned as a function of the internal diameter of the sleeve 20 for extension, so to facilitate the palletizing of similar wheels. Two wheels can be stacked one on the other by placing the bulb 30 of an upper wheel in the sheath 20 for extending a lower wheel. Moreover, thanks to this arrangement, the head 31 of the support pin 7 can be housed inside the bulb 30. The groove 6 of the support pin 7 and the locking pins 24 are thus brought closer to the outer flange 2. This improves the resistance of the wheel on the support axis 7, because the forces exerted on the wheel are arranged in the median plane 32 thereof, that is to say outside the groove 6.
Dans les modes de réalisation décrits ci-dessus, le bandage 12 est réalisé en un matériau recyclable de même nature que le matériau constitutif du reste de la roue. La jante selon l'invention peut également être équipée d'un bandage en poudrette ou en caoutchouc en lieu et place du bandage en polyéthylène. Dans ce cas, il faudra préalablement déjanter la roue lors du recyclage. In the embodiments described above, the tire 12 is made of a recyclable material of the same kind as the material constituting the rest of the wheel. The rim according to the invention can also be equipped with a powder or rubber bandage in place of the polyethylene bandage. In this case, the wheel must first be disjointed during recycling.
