Abstract
Description
L'invention a trait sous son aspect le plus général à une brosse destinée à être entraînée par des moyens de mise en rotation.The invention relates in its most general aspect to a brush intended to be driven by means of rotation.
Les brosses rotatives classiques donnent en général toute satisfaction, mais elles introduisent des difficultés dans certains cas, par exemple quand on désire brosser transversalement sur une grande largeur, situation dans laquelle on doit utiliser une brosse particulièrement encombrante puisque la largeur de brossage correspond au diamètre de la brosse.Conventional rotary brushes are generally satisfactory, but they introduce difficulties in certain cases, for example when it is desired to brush transversely over a large width, a situation in which a particularly bulky brush must be used since the brushing width corresponds to the diameter of the brush.
On a déjà proposé (voir DE-A-2.825.090) une brosse comportant une courroie dont le profil extérieur est muni de poils grâce à des corps rigides collés sur la courroie, et dont le profil intérieur présente des dents pour coopérer avec des poulies rotatives.A brush has already been proposed (see DE-A-2,825,090) comprising a belt whose external profile is provided with bristles by means of rigid bodies glued to the belt, and whose internal profile has teeth to cooperate with pulleys rotary.
L'invention vise à augmenter les possibilités des brosses entraînées par des moyens de mise en rotation.The invention aims to increase the possibilities of brushes driven by means of rotation.
Elle propose à cet effet une brosse comportant une courroie munie de poils sur son profil extérieur tandis que son profil intérieur est adapté a coopérer avec des poulies rotatives, caractérisée en ce que les poils sont implantés de manière oblique sur la courroie.To this end, it offers a brush comprising a belt provided with bristles on its external profile while its internal profile is adapted to cooperate with rotary pulleys, characterized in that the bristles are installed obliquely on the belt.
Celle-ci peut ainsi être disposée suivant un plan ayant une orientation similaire à la surface à brosser, ce qui offre l'avantage de limiter l'encombrement en hauteur de la brosse au-dessus de cette surface.The latter can thus be arranged in a plane having an orientation similar to the surface to be brushed, which offers the advantage of limiting the overall height of the brush above this surface.
Dans la brosse selon l'invention, la monture portant les poils n'est pas un plateau circulaire ou un cylindre rigides, mais une courroie à qui on peut faire prendre les contours les plus divers en agissant sur le nombre, la taille et la disposition des poulies avec lesquelles elle coopère.In the brush according to the invention, the frame carrying the bristles is not a circular plate or a rigid cylinder, but a belt which can be made to take the most diverse contours by acting on the number, size and arrangement. pulleys with which it cooperates.
Elle peut ainsi prendre dans un cas particulièrement simple, en coopérant avec deux poulies relativement éloignées l'une de l'autre comparativement à leur diamètre, une forme oblongue qui offre l'avantage de permettre un brossage transversal sur une grande largeur avec un encombrement longitudinal très réduit.It can thus take in a particularly simple case, by cooperating with two relatively pulleys distant from each other compared to their diameter, an oblong shape which offers the advantage of allowing a transverse brushing over a large width with a very reduced longitudinal bulk.
Elle peut aussi prendre un contour polygonal avec davantage de poulies, par exemple un contour triangulaire qui permet de brosser longitudinalement un creux en V, y compris la pointe.It can also take a polygonal contour with more pulleys, for example a triangular contour which makes it possible to brush longitudinally a V-shaped hollow, including the tip.
De plus, si l'une des poulies a un diamètre relativement petit, elle permet à la brosse d'atteindre le fond des recoins situés devant cette petite poulie.In addition, if one of the pulleys has a relatively small diameter, it allows the brush to reach the bottom of the recesses located in front of this small pulley.
En outre de l'augmentation des possibilités des brosses entraînées par des moyens rotatifs qu'elle procure, la brosse selon l'invention offre également l'avantage de présenter un poids réduit par rapport aux brosses rotatives classiques, étant donné qu'elle est formée par volume de matière plus réduit.In addition to the increase in the possibilities of brushes driven by rotary means which it provides, the brush according to the invention also offers the advantage of having a reduced weight compared to conventional rotary brushes, since it is formed by reduced volume of material.
L'invention concerne aussi, sous un deuxième aspect, un ensemble de brossage comportant des poulies rotatives et une brosse telle que précédemment exposée ; et notamment un ensemble de brossage présentant une forme oblongue.The invention also relates, in a second aspect, to a brushing assembly comprising rotary pulleys and a brush as previously exposed; and in particular a brushing assembly having an oblong shape.
L'ensemble de brossage présente avantageusement cette forme, pour des raisons de simplicité, grâce à un support oblong sur lequel sont montées les poulies, et il comporte de préférence sur ledit support un moteur pour entraîner une des poulies, il est en effet particulièrement commode que le moteur qui met en mouvement la brosse soit sur le même support que les poulies, l'ensemble de brossage pouvant ainsi être mobile par simple déplacement du support.The brushing assembly advantageously has this shape, for reasons of simplicity, thanks to an oblong support on which the pulleys are mounted, and it preferably comprises on said support a motor to drive one of the pulleys, it is indeed particularly convenient that the motor which sets the brush in motion is on the same support as the pulleys, the brushing assembly can thus be movable by simple movement of the support.
L'invention concerne également, sous un troisième aspect, un engin de nettoyage comportant au moins un ensemble de brossage tel que précédemment exposé.The invention also relates, in a third aspect, to a cleaning machine comprising at least one brushing assembly as described above.
Sous ce même aspect, elle concerne en particulier les engins de nettoyage du genre comportant un corps mobile, un outil ventral pour amener dans un bac des déchets se trouvant sous le corps, et de chaque côté du corps en avant de l'outil ventral, un outil latéral pour ramener vers l'outil ventral les déchets se trouvant sur les côtés du corps ; les engins conformes à l'invention se caractérisant en ce que les outils latéraux comportent un ensemble de brossage oblong tel que précédemment exposé.In this same aspect, it relates in particular to cleaning machines of the kind comprising a movable body, a ventral tool for bringing into a bin waste located under the body, and on each side of the body in front of the ventral tool, a lateral tool for bringing back to the ventral tool the waste located on the sides of the body; the machines according to the invention characterized in that the lateral tools include an oblong brushing assembly as previously exposed.
Ils offrent ainsi l'avantage de présenter de chaque côté une largeur de nettoyage latérale importante sous un encombrement longitudinal réduit ; et permettent en outre, grâce à l'extrémité de leur outil latéral, que soient nettoyés les recoins des parois qu'ils longent.They thus offer the advantage of having on each side a large lateral cleaning width under a reduced longitudinal bulk; and also allow, thanks to the end of their lateral tool, to be cleaned the recesses of the walls they run along.
Selon des caractéristiques préférées, les outils latéraux sont mobiles en translation selon une direction transversale audit corps, afin de faire varier la largeur de nettoyage de l'engin. En effet, grâce à leur caractère oblong, les outils latéraux sont aisément rectractables dans le corps suivant un mouvement transversal qui permet aux outils latéraux de rester correctement positionnés par rapport à l'outil ventral.According to preferred characteristics, the lateral tools are movable in translation in a direction transverse to said body, in order to vary the cleaning width of the machine. Indeed, thanks to their oblong nature, the lateral tools are easily rectractable in the body in a transverse movement which allows the lateral tools to remain correctly positioned relative to the ventral tool.
L'exposé de l'invention sera maintenant poursuivi par la description d'exemples de réalisation de l'invention sous ses divers aspects, faite ci-après à titre illustratif et non limitatif en regard des dessins annexés sur lesquels :
- la figure 1 est une vue schématique en plan d'un ensemble de brossage comportant une brosse conforme à l'invention coopérant avec deux poulies dont la taille et la disposition lui donnent un contour oblong ;
- la figure 2 est la vue en coupe indiquée en II-II sur la figure 1 ;
- la figure 3 est une vue schématique en élévation d'un engin de nettoyage conforme à l'invention ;
- la figure 4 est une vue de dessus de cet engin ;
- la figure 5 illustre de façon plus détaillée l'un des outils de brossage latéral de cet engin, suivant une coupe prise selon la ligne V-V de la figure 4 ;
- la figure 6 est la coupe indiquée en VI-VI sur la figure 5 ; et
- la figure 7 est une vue de dessous de cet outil latéral.
- Figure 1 is a schematic plan view of a brushing assembly comprising a brush according to the invention cooperating with two pulleys whose size and arrangement give it an oblong outline;
- Figure 2 is the sectional view indicated in II-II in Figure 1;
- Figure 3 is a schematic elevational view of a cleaning machine according to the invention;
- Figure 4 is a top view of this machine;
- FIG. 5 illustrates in more detail one of the lateral brushing tools of this machine, according to a section taken along line VV of FIG. 4;
- Figure 6 is the section indicated in VI-VI in Figure 5; and
- Figure 7 is a bottom view of this side tool.
Comme on le voit sur les figures 1 et 2, la brosse de l'ensemble de brossage 1 représenté comporte une courroie 2 muni de poils 3 sur toute sa longueur, mais que l'on n'a ici illustré que partiellement pour simplifier le dessin. Les poils 3 sont implantés par touffes sur le profil extérieur de la courroie 2 tandis que son profil intérieur est adapté à coopérer avec des poulies rotatives 4 et 5 que comporte également l'ensemble de brossage 1.As seen in Figures 1 and 2, the brush of the
Les poulies 4 et 5, dont l'une est menante et l'autre menée, sont relativement éloignées l'une de l'autre comparativement à leur diamètre, de telle sorte que l'ensemble de brossage 1 présente une forme oblongue. Ainsi qu'on le voit sur la figure 2, les poils 3 sont implantés de manière oblique sur la courroie, ce qui permet à la brosse 2,3 d'être disposée au-dessus de la surface 6 suivant un plan ayant une orientation similaire, la brosse étant en contact avec la surface 6 par le bout des poils 3 sans que la courroie 2 ni les poulies 4 et 5 ne la touchent.The
On observera que si les poils avaient été implantés droit, il aurait fallu disposer la courroie suivant un plan transversal à celui de la surface 6 pour pouvoir réaliser un brossage transversal similaire, ce qui aurait nécessité un encombrement en hauteur beaucoup plus important.It will be observed that if the bristles had been implanted straight, it would have been necessary to have the belt in a plane transverse to that of the
On observera aussi que pour obtenir la même largeur de brossage transversal avec une brosse rotative classique, cette dernière devrait avoir un diamètre égal à la plus grande dimension de l'ensemble de brossage 1, elle aurait donc un encombrement longitudinal beaucoup plus important, et de plus on ne pourrait pas brosser le fond des recoins que l'on peut atteindre ici.It will also be observed that in order to obtain the same transverse brushing width with a conventional rotary brush, the latter should have a diameter equal to the largest dimension of the
L'engin de nettoyage 7 illustré sur les figures 3 et 4 comporte un corps mobile 8, un outil ventral 9 pour amener dans un bac 10 des déchets se trouvant sous le corps, et de chaque côté du corps 8, en avant de l'outil ventral 9, un outil latéral 11A et 11B comportant un ensemble de brossage 1, pour ramener vers l'outil ventral les déchets se trouvant sur les côtés du corps, les poulies 4 tournant dans le sens indiqué par une flèche, l'engin 7 se déplaçant de la droite vers la gauche des figures 3 et 4.The
Les outils latéraux 11A et 11B sont mobiles en translation suivant une direction transversale au corps 8, illustrée par les flèches doubles 12, entre la position sortie extreme représentée et la position rétractée extreme montrée en trait mixte sur la figure 4.The
Ainsi, dans chaque position, ils gardent leur orientation en biais suivant les directions qui forment un V dont la pointe se situe dans le corps 8, de telle sorte qu'ils continuent à ramener les déchets vers l'outil ventral 9 quelle que soit la position qu'on leur a donné pour faire varier la largeur de nettoyage de l'engin 7.Thus, in each position, they keep their orientation at an angle along the directions which form a V, the point of which is located in the
On notera que celui-ci est particulièrement compact par rapport à sa largeur de nettoyage et à l'amplitude des variations de cette largeur. A titre d'exemple, l'engin illustré a un corps dont la longueur est de 40 cm tandis que la largeur maximale de nettoyage est de 82,5 cm.Note that it is particularly compact with respect to its cleaning width and the amplitude of the variations of this width. As an example, the machine illustrated has a body whose length is 40 cm while the maximum cleaning width is 82.5 cm.
On va maintenant décrire plus en détail l'ensemble de nettoyage 1, en référence aux figures 5 à 7.We will now describe in more detail the
Les poulies 4 et 5 sont montées sur un support oblong 13, sur lequel est disposé un moteur 14 pour entraîner la poulie 4, à laquelle il est relié par un joint de Oldham 15 et un réducteur 16, une poulie supplémentaire 17 de plus petit diamètre étant prévue pour tendre la courroie 2, c'est-à-dire que l'ensemble 1 comporte finalement trois poulies disposées en triangle sur le support 13, la poulie menante 4 à l'une des extrémités du support, la poulie menée 5 à l'autre extrémité et la poulie 17 qui forme le troisième sommet du triangle.The
Ainsi que l'illustre la figure 5, l'ensemble 1 est incliné de telle sorte que ce soit uniquement les poils situés en avant de l'engin qui sont en contact avec la surface 6, c'est-à-dire uniquement la partie utile de la brosse, ce qui offre l'avantage de minimiser les frottements auxquels est soumise la brosse, et par conséquent l'usure de celle-ci et l'énergie consommée.As illustrated in Figure 5, the
Les poulies et la courroie sont toutes disposées en dessous du support 13, la courroie 2 est une courroie du type bien connu dit "dentée", un capot 18 est prévu pour le moteur 14 et un capot 19 pour le joint 15 et le réducteur 16, tandis que des tiges 20A et 20B sont montées sur la plaque-support 13 pour permettre de relier l'ensemble l au reste de l'engin 7.The pulleys and the belt are all arranged below the
Dans ce dernier, l'outil ventral 9 est formé par des brosses cylindriques 21 et 22 disposées transversalement, la brosse 22 réalisant un brossage longitudinal de la surface à nettoyer ; le corps 8 est mobile grâce à deux groupes motopropulseurs 23A et 23B disposés sur les côtés respectifs du corps, comportant chacun un moteur 24 et une roue 25 ; un ensemble d'aspiration est prévu dans le compartiment 26, un ensemble électronique est disposé dans le compartiment 27 et des batteries dans le compartiment 28, en dessous duquel se trouve une roue folle 29, tandis qu'une poignée 30 est prévue à l'avant de l'engin.In the latter, the
On notera que cet engin est muni des moyens lui permettant d'agir de façon autonome pour nettoyer un local, et qu'il est l'un des objets d'une demande de brevet déposée conjointement à la présente demande.It will be noted that this machine is provided with means enabling it to act independently to clean a room, and that it is one of the objects of a patent application filed jointly with the present application.
