Description

La présente invention a essentiellement pour objet un dispositif permettant un nettoyage particulièrement rapide et efficace des vitres, des meubles et de tous objets analogues comportant des surfaces à nettoyer de temps à autre.The present invention essentially relates to a device allowing a particularly fast and efficient cleaning of windows, furniture and all like objects having surfaces to be cleaned from time to time.

Elle trouve une application particulièrement avantageuse dans le nettoyage des vitres de bâtiments ou de véhicules.It finds a particularly advantageous application in cleaning windows of buildings or vehicles.

Les utilisateurs de véhicules automobiles connaissent bien la gêne qu'occasionne la pellicule grasse qui se forme sur l'intérieur des vitres au bout d'un certain temps. Cette pellicule est d'ailleurs connue dans la technique sous la dénomination de "fogging".Motor vehicle users are well aware of the discomfort caused by the oily film that forms on the inside of the windows at the end of a certain time. This film is moreover known in the art as the name "fogging".

Le "fogging" est dû à des dépôt chimiques provenant des garnitures en matière plastique de l'intérieur du véhicule, et aussi des gaz polluants notamment des gaz d'échappement diffusés par les ouïes d'aération. Cette pellicule de "fogging" est encore accentuée dans les véhicules dont les occupants sont des fumeurs.The "fogging" is due to chemical deposits coming from the material linings plastic inside the vehicle, and also polluting gases including exhaust gases diffused by the air vents. This film of "fogging" is further accentuated in vehicles whose occupants are smokers.

Actuellement, le nettoyage se fait le plus souvent à l'aide d'un pulvérisateur de produit liquide qui est étendu et essuyé avec un chiffon. La pulvérisation des liquides nettoyants déborde souvent des surfaces à nettoyer et retombe notamment sur le tableau de bord du véhicule de sorte qu'il est nécessaire de nettoyer non seulement le pare-brise mais encore le tableau de bord.Currently, cleaning is most often done using a sprayer liquid product which is spread out and wiped with a cloth. Spraying cleaning fluids often overflows from surfaces to be cleaned and falls back especially on the dashboard of the vehicle so it is necessary to not only clean the windshield but also the dashboard.

Au surplus, même après un nettoyage appliqué et souvent pénible, il reste encore sur la vitre des traces de "fogging", notamment dans les endroits difficilement accessibles de la vitre, tels que par exemple dans les coins de cette vitre.In addition, even after an applied and often painful cleaning, it remains still traces of "fogging" on the glass, especially in places difficult to access from the glass, such as for example in the corners of that window.

Pour remédier aux inconvénients du nettoyage après pulvérisation préalable d'un produit liquide sur la surface à nettoyer, il a été proposé d'utiliser des tampons de nettoyage comprenant essentiellement une plaque rigide munie sur une face d'une ou plusieurs couches de matériau absorbant susceptibles de retenir un produit liquide de nettoyage, tandis que l'autre face de la plaque comporte un moyen de préhension permettant la manoeuvre du tampon de nettoyage.To overcome the disadvantages of cleaning after prior spraying of a liquid product on the surface to be cleaned, it has been proposed to use cleaning pads essentially comprising a rigid plate provided on one side of one or more layers of absorbent material susceptible to retain a liquid cleaning product, while the other side of the plate includes a gripping means allowing the operation of the cleaning.

Mais un tel système est loin d'être satisfaisant, car, bien souvent, il ne permet toujours pas un nettoyage efficace de l'objet ou de la vitre dans les endroits difficilement accessibles, et, même après un nettoyage soigneux, le produit liquide et souillé s'étale plus ou moins, et il reste toujours des traces ou des irisations qui sont dangereuses notamment sur les vitres des véhicules automobiles, en conduite nocturne, car elles peuvent provoquer un éblouissement du conducteur.But such a system is far from satisfactory, because very often it does not allow still not an effective cleaning of the object or the glass in places difficult to access, and even after careful cleaning, the product liquid and soiled spreads more or less, and there are always traces or iridescence which is dangerous, in particular on vehicle windows cars, when driving at night, because they can cause driver glare.

Aussi, la présente invention a notamment pour but de remédier aux inconvénients ci-dessus en proposant un dispositif perfectionné qui permet le nettoyage d'une vitre ou d'un objet quelconque comportant une ou des surfaces à nettoyer, ce nettoyage pouvant s'exercer facilement et sans effort, avec un minimum de passes, sur la totalité de la surface à nettoyer, et évitant avantageusement, après le nettoyage, de laisser sur ces surfaces des traces de salissure étalées par le dispositif.Also, the present invention aims in particular to remedy the disadvantages above by proposing an improved device which allows the cleaning a window or any object containing one or more surfaces to be cleaned, this cleaning being able to be carried out easily and without effort, with a minimum of passes, over the entire surface to be cleaned, and avoiding advantageously, after cleaning, leave traces on these surfaces of dirt spread by the device.

A cet effet, l'invention a pour objet un dispositif de nettoyage pour vitres, meubles et objets analogues du type comprenant une plaque rigide ou semi-rigide munie, sur une face, d'au moins une couche de matériau absorbant et, sur l'autre face d'un moyen préhension, caractérisé en ce que ladite couche de matériau absorbant est une couche de mousse de polyuréthane feutré, et à cette couche est associée au moins une couche sous-jacente en matière hydrophile constamment et régulièrement imprégnée de liquide de nettoyage retenu dans ladite couche de mousse de polyuréthane feutré.To this end, the invention relates to a cleaning device for windows, furniture and the like of the type comprising a rigid or semi-rigid plate provided, on one side, with at least one layer of absorbent material and, on the other side of a gripping means, characterized in that said layer of absorbent material is a layer of felted polyurethane foam, and this layer is associated with at least one underlying layer of material hydrophilic constantly and regularly impregnated with cleaning fluid retained in said layer of felted polyurethane foam.

Suivant un mode de réalisation préféré, la couche sous-jacente en matière hydrophile est un voile de viscose perforé. According to a preferred embodiment, the underlying layer of material hydrophilic is a veil of perforated viscose.

Suivant un mode de réalisation préféré, le voile de viscose est un non-tissé de poids égal à environ 75 g/m2.According to a preferred embodiment, the viscose veil is a nonwoven of weight equal to approximately 75 g / m 2 .

A ce voile de viscose est associé un voile de polyester sous-jacent.This viscose veil is associated with an underlying polyester veil.

Ce voile de polyester est de préférence un non-tissé de poids égal à environ 25 g/m2.This polyester veil is preferably a nonwoven of weight equal to approximately 25 g / m 2 .

Le dispositif de cette invention est encore caractérisé en ce que la plaque précitée présente sensiblement la forme d'un triangle à angles arrondis ou non.The device of this invention is further characterized in that the plate above has substantially the shape of a triangle with rounded angles or not.

Les côtés du triangle peuvent être légèrement convexes.The sides of the triangle may be slightly convex.

Suivant une autre caractéristique de l'invention, le moyen précité de préhension de la plaque est un pommeau situé de préférence au voisinage de l'un des angles du triangle que forme la plaque.According to another characteristic of the invention, the aforementioned means of gripping the plate is a knob preferably located in the vicinity of one of the angles of the triangle formed by the plate.

Suivant encore une autre caractéristique du dispositif de l'invention, la couche de matériau absorbant en mousse de polyuréthane feutré est collée ou soudée sur la plaque précitée, tandis que le voile en viscose et le voile en polyester forment un ensemble monté coiffant sur la plaque.According to yet another characteristic of the device of the invention, the layer absorbent material of felted polyurethane foam is glued or welded on the aforementioned plate, while the viscose veil and the polyester veil form a mounted assembly capping on the plate.

Cet ensemble peut donc être avantageusement jetable et remplaçable.This assembly can therefore be advantageously disposable and replaceable.

Suivant une autre caractéristique de l'invention, le pommeau et la plaque proprement dite sont réalisés en un matériau synthétique différent et sont fixés l'un à l'autre par tout moyen approprié tel que par exemple soudage ou collage.According to another characteristic of the invention, the knob and the plate proper are made of a different synthetic material and are fixed to each other by any suitable means such as for example welding or gluing.

On précisera encore ici que sur la face de la plaque portant le pommeau est prévue une creusure allongée prenant naissance au niveau du raccordement du pommeau à la plaque. It will also be specified here that on the face of the plate carrying the knob is provided an elongated recess starting at the connection from the knob to the plate.

Ainsi, le dispositif pourra être mieux tenu en main et contrôlé lors du nettoyage par le fait que l'utilisateur pourra appliquer un doigt de sa main dans la creusure précitée.Thus, the device can be better held in hand and controlled during cleaning by the fact that the user can apply a finger of his hand in the aforementioned recess.

Mais d'autres avantages et caractéristiques de l'invention apparaítront mieux dans la description détaillée qui suit et se réfère aux dessins annexés, donnés uniquement à titre d'exemple dans lesquels :

  • la figure 1 est une vue en plan de dessus du dispositif de nettoyage de cette invention ;
  • la figure 2 est une vue en coupe de ce dispositif suivant la ligne II-II de la figure 1; et
  • la figure 3 est une vue en perspective de ce dispositif avec arrachements partiels de la plaque et des couches successives qui le constituent.
However, other advantages and characteristics of the invention will appear better in the detailed description which follows and refers to the appended drawings, given solely by way of example in which:
  • Figure 1 is a top plan view of the cleaning device of this invention;
  • Figure 2 is a sectional view of this device along the line II-II of Figure 1; and
  • Figure 3 is a perspective view of this device with partial cutaway of the plate and the successive layers which constitute it.

Suivant un exemple de réalisation, et comme on le voit sur les dessins, un dispositif de nettoyage conforme à cette invention comprend essentiellement une plaque 1 en matière rigide ou semi-rigide sur une face 2 de laquelle sont fixées de façon superposée et successivement une couche 3 de matériau absorbant, une couche 4 sous-jacente de matériau hydrophile, et un voile 5 de polyester.According to an exemplary embodiment, and as seen in the drawings, a cleaning device according to this invention essentially comprises a plate 1 of rigid or semi-rigid material on one face 2 of which are superimposed successively a layer 3 of material absorbent, an underlying layer 4 of hydrophilic material, and a veil 5 of polyester.

Ces éléments superposés seront décrits ci-après en détail avec leurs avantages respectifs et en combinaison avec les autres éléments.These superimposed elements will be described below in detail with their respective advantages and in combination with the other elements.

La plaque proprement dite 1 est en une matière rigide ou semi-rigide légèrement flexible, par exemple en une matière plastique du genre polystyrène ou analogue.The actual plate 1 is made of a rigid or semi-rigid material slightly flexible, for example a plastic like polystyrene or the like.

Elle comporte sur sa face 6, opposée à la face 2 portant les couches successives 3, 4 et 5, un pommeau 7 formant en quelque sorte une poignée de préhension et de manoeuvre du dispositif de nettoyage selon cette invention constitué par l'ensemble plaque 1 et couches 3, 4 et 5.It has on its face 6, opposite to the face 2 carrying the layers successive 3, 4 and 5, a knob 7 forming a sort of handle of gripping and operating the cleaning device according to this invention consisting of the plate 1 and layers 3, 4 and 5 assembly.

Suivant l'exemple de réalisation représenté, et comme on le voit bien sur la figure 2, le pommeau 7 et la plaque proprement dite 1 forment deux pièces réalisées en une matière synthétique différente. Ainsi, la plaque 1 peut être, comme indiqué précédemment, en polystyrène, tandis que le pommeau 7 peut être en une autre matière synthétique et comporter sur sa surface des aspérités ou des reliefs en creux pour ainsi former une surface d'accrochage meilleure assurant une bonne préhension par la main de l'utilisateur. Comme on le voit encore sur la figure 2, le pommeau 7 et la plaque 1 sont fixés l'un à l'autre par l'intermédiaire d'un épaulement 11 entre ledit pommeau et une partie 12 en forme de cheminée faisant saillie de la face 6 de la plaque 1. La fixation au niveau de l'épaulement peut être effectuée par tout moyen approprié tel que par exemple collage, soudage ou autre technique.According to the embodiment shown, and as we can see on the Figure 2, the knob 7 and the plate itself 1 form two parts made of a different synthetic material. So plate 1 can be, as indicated above, in polystyrene, while the knob 7 can be of another synthetic material and have on its surface roughness or recessed reliefs to thereby form a gripping surface better ensuring good grip by the user's hand. As we still see in Figure 2, the knob 7 and the plate 1 are fixed one to the other by means of a shoulder 11 between said pommel and a part 12 in the form of a chimney projecting from the face 6 of the plate 1. The fixing at the level of the shoulder can be carried out by any appropriate means such as for example gluing, welding or other technique.

Bien entendu, le pommeau 7 et la plaque 1 pourraient parfaitement, sans sortir du cadre de l'invention, former une pièce unique réalisée, par exemple, par moulage par injection.Of course, the knob 7 and the plate 1 could perfectly, without going out within the scope of the invention, form a single piece produced, for example, by injection molding.

On a montré en 10 une empreinte ou creusure allongée pratiquée dans la face 6 de la plaque 1. Cette creusure prend naissance au niveau du raccordement du pommeau 7 à la plaque 1, comme on le voit bien sur les figures. Elle peut avantageusement recevoir l'index de la main de l'utilisateur qui tient le pommeau 7, et facilite par conséquent l'application du dispositif et sa manoeuvre sur la surface à nettoyer. On observera encore que l'empreinte ou creusure 10 comporte des aspérités évitant le glissement de l'index de la main dans ladite empreinte ou creusure.We have shown in 10 an elongated impression or recess made in the face 6 of plate 1. This recess begins at the connection from the knob 7 to the plate 1, as can be seen in the figures. She can advantageously receive the index finger of the user who holds the knob 7, and therefore facilitates the application of the device and its operation on the surface to be cleaned. We will also observe that the imprint or indentation 10 has roughness preventing the index finger from sliding off in said footprint or recess.

Par ailleurs, la plaque 1, comme il apparaít clairement sur les figures, présente sensiblement la forme d'un triangle dont les angles 8 peuvent être plus ou moins arrondis ou non. Egalement, certains angles du triangle que constitue la plaque 1 peuvent être plus arrondis que les autres, comme on le voit bien sur la figure 1, le pommeau précité 7 étant situé, suivant l'exemple de réalisation représenté, au voisinage de l'un des angles du triangle que forme la plaque.Furthermore, the plate 1, as it appears clearly in the figures, has substantially the shape of a triangle whose angles 8 can be more or less rounded or not. Also, certain angles of the triangle that constitutes the plate 1 can be more rounded than the others, as we can see on Figure 1, the aforementioned knob 7 being located, according to the embodiment shown, in the vicinity of one of the angles of the triangle formed by the plate.

On observera encore que les côté 9 du triangle formant la plaque 1 sont légèrement convexes.It will also be observed that the sides 9 of the triangle forming the plate 1 are slightly convex.

La plaque 1 permet, d'une manière générale, d'assurer une pression uniforme sur les surfaces à nettoyer (vitres de véhicule ou vitrines de boutiques par exemple), ce qui conditionne, entre autres, une bonne efficacité de nettoyage. En outre, si la platine est semi-rigide, elle peut épouser étroitement les courbures de la vitre à nettoyer ce qui est particulièrement valable pour la face interne des pare-brises de voiture notamment, étant entendu que l'un des angles 8 de la platine peut être moins arrondi que les autres, comme on le voit sur la partie gauche des figures 1 et 3, de façon à permettre un nettoyage efficace dans les recoins. Bien entendu, des modifications de la forme et des dimensions de la plaque 1 peuvent parfaitement être envisagées en fonction de l'application, sans sortir du cadre de l'invention.The plate 1 generally makes it possible to ensure uniform pressure on the surfaces to be cleaned (vehicle windows or shop windows by example), which conditions, among other things, good cleaning efficiency. In addition, if the plate is semi-rigid, it can closely fit the curvatures of the glass to be cleaned which is particularly valid for the face internal of car windshields in particular, it being understood that one of the 8 angles of the plate can be less rounded than the others, as we see on the left side of Figures 1 and 3, so as to allow cleaning effective in the nooks and crannies. Of course, changes in the form and dimensions of plate 1 can perfectly be envisaged depending on of the application, without departing from the scope of the invention.

La couche 3 de matériau absorbant est fixée par collage ou soudage sur la face 2 de la plaque 1.The layer 3 of absorbent material is fixed by gluing or welding to the side 2 of plate 1.

Cette couche 3 est de préférence une couche de mousse de polyuréthane feutré qui joue le rôle d'un réservoir et qui présente l'avantage d'absorber une certaine quantité de liquide de nettoyage, lequel ne peut pas être restitué en totalité lorsqu'on exerce une pression sur cette couche. La couche 3 de mousse de polyuréthane feutré pourra être pré-imprégnée de liquide de nettoyage, ou bien elle pourra être imprégnée de ce liquide seulement lors de l'utilisation du dispositif.This layer 3 is preferably a layer of polyurethane foam felted which plays the role of a reservoir and which has the advantage of absorbing a a certain amount of cleaning fluid, which cannot be returned in all when pressure is applied to this layer. Layer 3 of felted polyurethane foam can be pre-impregnated with liquid cleaning, or it may be impregnated with this liquid only when use of the device.

La couche 3 est de préférence une couche de mousse réticulée de polyuréthanne à réseau cellulaire complètement ouvert, du type connu sous la marque de fabrique BULPREN. La couche 3 formée d'un tel matériau peut avoir une épaisseur comprise entre environ 2 et 10 mm. Layer 3 is preferably a layer of cross-linked foam of polyurethane with a completely open cellular network, of the type known as BULPREN trademark. Layer 3 formed of such a material can be between 2 and 10 mm thick.

La couche sous-jacente 4 en matière hydrophile sera constituée par un voile de viscose perforé. On a montré schématiquement en 4a les perforations de ce voile de viscose 4.The underlying layer 4 of hydrophilic material will consist of a veil of perforated viscose. We have shown schematically in 4a the perforations of this viscose veil 4.

Le voile de viscose perforé 4 est de préférence un non-tissé de poids égal à environ 75 g/m2, du type connu sous la marque enregistrée NORAFIN. Un tel voile perforé 4 présente l'avantage d'être absorbant, diffuseur et capteur de salissures en raison de la présence des perforations dans ledit voile.The perforated viscose veil 4 is preferably a nonwoven with a weight equal to approximately 75 g / m 2 , of the type known under the registered trademark NORAFIN. Such a perforated veil 4 has the advantage of being absorbent, diffuser and dirt sensor due to the presence of the perforations in said veil.

Plus précisément, ce voile 4 coopère avantageusement avec la couche absorbante 3 de mousse de polyuréthanne feutré, en ce sens qu'il travaille à la manière d'une mèche d'absorption du liquide de nettoyage dans ladite couche, de sorte que le voile 4 demeure constamment et régulièrement imprégné de liquide de nettoyage retenu dans la couche 3. En d'autres termes, le voile de viscose 4 possède un rôle de régulateur car, en recherchant en permanence une saturation maximum, il rééquilibre son imprégnation en venant pomper dans la couche 3 formant réservoir le liquide qui a été prélevé sous.l'effet du nettoyage.More specifically, this veil 4 advantageously cooperates with the layer absorbent 3 of felted polyurethane foam, in the sense that it works at way of a wicking absorption of the cleaning liquid in said layer, so that the web 4 remains constantly and regularly impregnated with cleaning liquid retained in layer 3. In other words, the haze of viscose 4 has a regulatory role because, by constantly seeking maximum saturation, it rebalances its impregnation by coming to pump in the layer 3 forming a reservoir, the liquid which has been withdrawn under the effect of the cleaning.

Le voile de polyester 5, qui est plus mince que la couche de matériau absorbant 3 ou même que le voile de viscose 4, se compose, d'une manière générale, de longues fibres agglomérées d'une manière lâche et est donc susceptible d'être traversé par le liquide de nettoyage.Polyester fleece 5, which is thinner than the material layer absorbent 3 or even that the viscose veil 4, is composed, in a way general, long fibers loosely agglomerated and therefore is likely to be crossed by the cleaning liquid.

Ce voile de polyester 5 peut être du type connu sous la marque déposée LUTRAVIL, et est un non-tissé possédant de préférence un poids égal à environ 25 g/m2. Il présente l'avantage d'être relativement rigide et de posséder des propriétés abrasives, tout en étant relativement perméable au liquide de nettoyage.This polyester veil 5 may be of the type known under the registered trademark LUTRAVIL, and is a nonwoven preferably having a weight equal to approximately 25 g / m 2 . It has the advantage of being relatively rigid and having abrasive properties, while being relatively permeable to cleaning liquid.

Du fait de sa texture, le voile de polyester 5, outre le fait qu'il confère au dispositif un bon effet de glissement sur la surface à nettoyer, présente aussi l'avantage de gratter légèrement les salissures sur ladite surface et surtout de retenir, dans les trous du voile, ces salissures dissoutes dans le liquide de nettoyage non évaporé.Because of its texture, the polyester veil 5, in addition to the fact that it gives the device a good sliding effect on the surface to be cleaned, also presents the advantage of slightly scratching the dirt on said surface and especially of retain, in the holes of the veil, these soils dissolved in the cleaning not evaporated.

Il faut encore préciser ici que, conformément à l'invention, le voile en viscose 4 et le voile en polyester 5 peuvent former un ensemble pré-assemblé qui peut être monté sur la couche 3 en mousse de polyuréthanne feutré, et cela en coiffant la plaque 1. Plus précisément, comme on le voit bien sur la figure 2, le bord 10 de l'ensemble des deux voiles 4 et 5 est replié pour venir coiffer les côtés 9 du triangle constituant la plaque rigide ou semi-rigide 1.It should also be specified here that, in accordance with the invention, the viscose veil 4 and polyester fleece 5 can form a pre-assembled assembly which can be mounted on layer 3 of felted polyurethane foam, and covering the plate 1. More precisely, as can be seen in FIG. 2, the edge 10 of the assembly of the two sails 4 and 5 is folded to come over the sides 9 of the triangle constituting the rigid or semi-rigid plate 1.

Ainsi, l'ensemble des deux voiles 4, 5, lorsqu'il sera plus ou moins saturé de salissures, pourra être avantageusement jeté et facilement remplacé par un ensemble propre.Thus, the assembly of the two sails 4, 5, when it is more or less saturated with dirt, can be advantageously discarded and easily replaced by a clean set.

On pourrait parfaitement, sans sortir du cadre de l'invention, faire en sorte que les voiles 4 et 5 ne soient pas séparables du dispositif, mais au contraire, qu'ils soient initialement solidaires du dispositif et non démontables.We could perfectly, without departing from the scope of the invention, ensure that the sails 4 and 5 are not separable from the device, but on the contrary, that they are initially secured to the device and not removable.

On a donc réalisé suivant l'invention un dispositif de nettoyage particulièrement efficace pour les vitres notamment, et cela avec un effort de pression minime sur la surface à nettoyer, et avec un nombre également minime de passes de frottement, étant bien entendu que, du fait de la géométrie particulière du dispositif, l'atteinte des recoins à nettoyer est facile et aucune trace de buée, et/ou de salissures résiduelles ou analogues ne sera présente après le nettoyage en raison de la combinaison spécifique des diverses couches constituant le dispositif et qui demeurent humectées de manière régulière, homogène et constante en liquide de nettoyage.We therefore produced according to the invention a particularly cleaning device effective for windows in particular, and this with minimal pressure effort on the surface to be cleaned, and with an equally minimal number of passes of friction, it being understood that, due to the particular geometry of the device, reaching the nooks to clean is easy and no trace of fogging, and / or residual soiling or the like will not be present after cleaning due to the specific combination of the various layers constituting the device and which remain regularly moistened, homogeneous and constant in cleaning liquid.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Of course, the invention is in no way limited to the embodiment described and illustrated which has been given only as an example.

C'est ainsi que le pommeau de préhension peut éventuellement être creux et former avantageusement un réservoir à liquide de nettoyage en contact avec la couche de matériau absorbant.This is how the grip knob can possibly be hollow and advantageously form a tank for cleaning liquid in contact with the layer of absorbent material.

C'est dire que l'invention comprend tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit.This means that the invention includes all the technical equivalents of means described as well as their combinations if these are carried out following his spirit.
