Description

La présente invention concerne un balai pour engin de nettoyage de la voirie, comprenant un plateau pouvant tourner autour d'un axe sensiblement vertical et perpendiculaire au plateau, plusieurs supports en forme de secteurs qui sont montés de manière détachable sous le plateau et qui portent des brins de nettoyage, chaque support comportant un bord extérieur, un bord intérieur et deux bords latéraux qui s'étendent sensiblement radialement par rapport à l'axe de rotation du plateau, et étant monté glissant horizontalement et supporté verticalement dans une paire de glissières radiales, qui sont fixées sous le plateau et qui coopèrent avec les bords latéraux du support correspondant.The present invention relates to a broom for a road cleaning machine, comprising a plate which can rotate about a substantially vertical axis and perpendicular to the plate, several supports in the form of sectors which are detachably mounted under the plate and which carry cleaning strands, each support having an outer edge, an inner edge and two lateral edges which extend substantially radially with respect to the axis of rotation of the plate, and being mounted sliding horizontally and supported vertically in a pair of radial slides, which are fixed under the plate and which cooperate with the lateral edges of the corresponding support.

Dans les engins de nettoyage de la voirie, il est connu d'utiliser des balais latéraux, à axe de rotation vertical, composé d'un plateau ou flasque en forme de disque rigide ou souple, qui est entraîné par un moteur, généralement un moteur hydraulique, et sous lequel sont fixés des supports en forme de secteur, qui portent des fils ou brins destinés au balayage.In road cleaning machines, it is known to use lateral brushes, with vertical axis of rotation, composed of a plate or flange in the form of a rigid or flexible disc, which is driven by a motor, generally a motor. hydraulic, and under which sector-shaped supports are fixed, which carry wires or strands intended for sweeping.

Il est connu de réaliser ces supports en tôle perforée, en aluminium coulé ou en plastique moulé, ces trois réalisations comportant des trous ou des encoches dans lesquels passent les fils ou brins de balayage. Il est également connu de fixer ces supports sous le plateau en les boulonnant ou en les maintenant par des rivets. Cette solution est efficace, mais longue à mettre en oeuvre. En particulier, l'opération de dépose des supports pour la rénovation des balais est longue, car elle nécessite d'abord le démontage du balai lui-même par rapport à son arbre d'entraînement, et ensuite le démontage de chacun des supports portant les brins de balayage. Or, lorsque lesdits supports sont fixés au plateau par des vis et des écrous, ceux-ci sont souvent rouillés et difficiles à dévisser, ou lorsqu'ils sont fixés par des rivets, ces derniers doivent être meulés ou coupés.It is known to produce these supports in perforated sheet metal, in cast aluminum or in molded plastic, these three embodiments comprising holes or notches in which the scanning wires or strands pass. It is also known to fix these supports under the plate by bolting them or holding them by rivets. This solution is effective, but time-consuming to implement. In particular, the operation of removing the supports for the renovation of the brushes is long, because it first requires the disassembly of the brush itself relative to its drive shaft, and then the disassembly of each of the supports carrying the sweep strands. However, when said supports are fixed to the plate by screws and nuts, these are often rusty and difficult to unscrew, or when they are fixed by rivets, the latter must be ground or cut.

Pour éviter ces inconvénients, il a déjà été proposé d'utiliser des glissières dans lesquelles viennent s'engager les supports. Dans ce cas, une ou deux vis suffisent à assurer le maintien de chaque support. Bien que cette solution représente une amélioration par rapport à la précédente, l'opération de démontage des supports reste quand même longue, car elle nécessite encore la dépose du balai lui-même et le dévissage de plusieurs vis.To avoid these drawbacks, it has already been proposed to use slides in which the supports engage. In this case, one or two screws are sufficient to maintain each support. Although this solution represents an improvement compared to the previous one, the operation of dismantling the supports still remains long, because it still requires the removal of the brush itself and the unscrewing of several screws.

Pour remédier à cet inconvénient, il a été proposé (brevet F R.2.550.428) d'utiliser des supports en matière plastique possédant une pince élastique qui vient s'encliqueter sur une cheville solidaire du plateau. Toutefois, cette solution simple ne donne pas toute satisfaction parce qu'il ne s'agit pas d'un verrouillage positif, mais d'un simple encliquetage. De ce fait, sous l'action de la force centrifuge due à la rotation du balai, et/ou sous l'action d'obstacles présents sur le sol, les fixations par encliquetage élastique peuvent se désemboîter et, par suite, les supports peuvent être désolidarisés du plateau.To remedy this drawback, it has been proposed (patent F R.2.550.428) to use plastic supports having an elastic clamp which snaps onto a dowel secured to the plate. However, this simple solution is not entirely satisfactory because it is not a positive locking, but a simple snap. Therefore, under the action of centrifugal force due to the rotation of the brush, and / or under the action of obstacles present on the ground, the elastic snap fasteners can disengage and, as a result, the supports can be separated from the tray.

La présente invention a donc pour but de fournir une solution simple à mettre en oeuvre, permettant une dépose et une repose rapides des supports, sans démontage du balai lui-même, tout en garantissant un maintien parfait des supports sous le plateau grâce à un verrouillage positif.The present invention therefore aims to provide a simple solution to implement, allowing rapid removal and installation of the supports, without disassembly of the brush itself, while ensuring perfect support of the supports under the plate thanks to a locking positive.

A cet effet, le balai de la présente invention est caractérisé en ce que chaque suppport comporte un trou dans l'un de ses bords latéraux, en ce qu'une cheville d'arrêt est engagée dans chaque trou des supports, à l'exception du trou d'un seul support, et coopère avec l'une des deux glissières associées au support correspondant pour empêcher tout mouvement radial dudit support vers l'extérieur du plateau quand ledit support est complètement engagé dans la paire de glissières correspondantes, et en ce que ledit seul support est installé en dernier dans la paire de glissières correspondantes et est retenu dans celles-ci par une vis traversant un trou du plateau et vissée dans un trou taraudé du support installé en dernier.To this end, the brush of the present invention is characterized in that each support has a hole in one of its lateral edges, in that a stop pin is engaged in each hole of the supports, with the exception of the hole of a single support, and cooperates with one of the two slides associated with the corresponding support to prevent any radial movement of said support towards the outside of the plate when said support is fully engaged in the pair of corresponding slides, and in that said only support is installed last in the pair of corresponding slides and is retained in these by a screw passing through a hole in the plate and screwed into a tapped hole in the support installed last.

De préférence, le trou de chaque support est un trou borgne, et chaque cheville a une longueur plus grande que la profondeur du trou, mais plus petite que la somme de ladite profondeur et de la largeur de l'espace entre les bords latéraux adjacents de deux supports adjacents.Preferably, the hole of each support is a blind hole, and each dowel has a length greater than the depth of the hole, but less than the sum of said depth and the width of the space between the adjacent side edges of two adjacent supports.

Avec un tel arrangement, le balai ne comporte qu'une seule vis de fixation, celle qui est prévue pour la fixation du dernier support installé sous le plateau, et tous les autres supports sont néanmoins maintenus positivement en place par les chevilles qui leur sont respectivement associées. En outre, comme on le verra en détail plus loin, les supports peuvent être montés sous le plateau et démontés de celui-ci de manière simple et rapide.With such an arrangement, the brush has only one fixing screw, that which is provided for fixing the last support installed under the plate, and all the other supports are nevertheless positively held in place by the pins which are respectively associated. In addition, as will be seen in detail below, the supports can be mounted under the tray and disassembled therefrom quickly and easily.

Le balai représenté dans les figures 1 et 2 comporte un plateau 1 en forme de disque, qui peut être fixé à l'extrémité inférieure d'un arbre vertical ou sensiblement vertical (non montré). Sous le plateau 1 sont montés un certain nombre de supports, par exemple douze supports 2a, 2b, ... 2l, en forme de secteur, qui portent chacun plusieurs fils ou brins 3 destinés au balayage. La manière dont les brins 3 sont attachés au support 2 est bien connue, de sorte qu'il n'est pas nécessaire de le décrire en détail.The brush shown in Figures 1 and 2 comprises a plate 1 in the form of a disc, which can be fixed to the lower end of a vertical or substantially vertical shaft (not shown). Under the plate 1 are mounted a number of supports, for example twelve supports 2 a , 2 b , ... 2 l , in the form of a sector, which each carry several wires or strands 3 intended for scanning. The way in which the strands 3 are attached to the support 2 is well known, so that it is not necessary to describe it in detail.

Comme cela est indiqué sur la figure 1 propos à du support 2a, et comme cela est également montré dans la figure 3, chacun des supports 2 comporte un bord extérieur 4, un bord intérieur 5 et deux bords latéraux 6 et 7, qui s'étendent radialement vers le centre du plateau 1. Chaque support 2 est supporté verticalement et peut glisser horizontalement dans une paire de glissières radiales 8 et 9, qui coopèrent respectivement avec les bords latéraux 6 et 7 de chaque support 2.As indicated in Figure 1 about to the carrier 2a, and as is also shown in Figure 3, each of the supports 2 comprises an outer edge 4, an inner edge 5 and two side edges 6 and 7 which s extend radially towards the center of the plate 1. Each support 2 is supported vertically and can slide horizontally in a pair of radial slides 8 and 9, which cooperate respectively with the lateral edges 6 and 7 of each support 2.

Conformément à la présente invention, chaque support 2 comporte un trou borgne 11 (figures 2 et 5) dans l'un de ses bords latéraux, par exemple dans son bord 6. Comme montré dans la figure 1, dans le trou 11 de chacun des supports 2a, 2b, ... 2k est engagée une cheville d'arrêt 12, mais aucune cheville d'arrêt n'est engagée dans le trou borgne du support 2l. Comme montré dans les figures 1 et 2, le trou 11 de chaque support 2 est situé à une distance d du bord extérieur 4 du support telle que, lorsque ledit support est complètement engagé dans la paire de glissières correspondantes 8 et 9 et que la cheville 12 est engagée dans le trou 11, ladite cheville se trouve à proximité immédiate de l'extrémité 8a de la glissière 8, qui est la plus proche du centre du plateau 1. De cette manière, la cheville 12 empêche le support 2 correspondant de se déplacer radialement vers l'extérieur après qu'il a été mis en place dans les glissières 8 et 9 et que la cheville 12 a été engagée dans le trou 11. En outre, comme montré dans la figure 5, chaque cheville a une longueur l plus grande que la profondeur p du trou 11, mais plus petite que la somme de ladite profondeur p et de la largeur e de l'espace entre les bords latéraux adjacents de deux supports adjacents, tels que par exemple les supports 2b et 2c de la figure 5. Ainsi, après que la cheville 12 a été engagée dans le trou 11 de l'un quelconque des supports, par exemple le support 2b, et après que le support adjacent,par exemple le support 2c, a été engagé dans la paire de glissières correspondantes, la cheville 12 du support 2b ne peut plus sortir du trou 11, de sorte que le support 2b est positivement verrouillé dans la paire de glissières correspondantes 8 et 9.According to the present invention, each support 2 has a blind hole 11 (FIGS. 2 and 5) in one of its lateral edges, for example in its edge 6. As shown in FIG. 1, in the hole 11 of each of supports 2 a , 2 b , ... 2 k is engaged a stop pin 12, but no stop pin is engaged in the blind hole of the support 2 l . As shown in Figures 1 and 2, the hole 11 of each support 2 is located at a distance d from the outer edge 4 of the support such that, when said support is fully engaged in the pair of corresponding slides 8 and 9 and that the pin 12 is engaged in the hole 11, the said pin is in the immediate vicinity of the end 8 a of the slide 8, which is closest to the center of the plate 1. In this way, the pin 12 prevents the corresponding support 2 from move radially outwards after it has been placed in the slides 8 and 9 and the pin 12 has been engaged in the hole 11. Furthermore, as shown in FIG. 5, each dowel has a length l greater than the depth p of the hole 11, but less than the sum of the said depth p and the width e of the space between the adjacent lateral edges of two adjacent supports, such as for example the supports 2 b and 2 c of FIG. 5. Thus, after the pin 12 has been engaged in the hole 11 of any of the supports, for example the support 2 b , and after the adjacent support, for example the support 2 c , has been engaged in the pair of corresponding slides, the pin 12 of the support 2 b can no longer come out of the hole 11, so that the support 2 b is positively locked in the pair of corresponding slides 8 and 9.

Comme montré dans les figures 3 et 4, chaque paire de glissières 8 et 9 peut être formée à partir d'une tôle métallique 13 convenablement découpée et pliée. La tôle 13 comporte une partie supérieure 14, qui est horizontale et plane et qui est destinée à être fixée par soudage ou par tout autre moyen approprié au plateau 1, et deux parties latérales 15 et 16, profilées en L, qui forment respectivement les glissières 8 et 9. Les branches verticales 15a et 16a des deux parties 15 et 16 sont respectivement attenantes aux bords latéraux 17 et 18 de la partie supérieure 14 de la tôle 13, qui font entre eux un angle égal à celui des bords latéraux 6 et 7 du support 2 et qui sont respectivement adjacents à ceux-ci. Les branches horizontales 15b et 16b des deux parties 15 et 16 sont orientées l'une vers l'autre et supportent latéralement le support 2. Bien que cela ne soit pas indispensable, mais seulement préférable pour mieux supporter le support 2, la tôle métallique 13 peut en outre comporter une autre partie 19 profilée en L, dont la branche verticale 19a est attenante au bord intérieur 21 de la partie supérieure 14 de la tôle 13, et dont la branche horizontale 19b s'étend au-dessous du bord intérieur 5 du support 2 pour le supporter comme montré dans les figures 2 et 3.As shown in Figures 3 and 4, each pair of slides 8 and 9 can be formed from a metal sheet 13 suitably cut and folded. The sheet 13 has an upper part 14, which is horizontal and planar and which is intended to be fixed by welding or by any other suitable means to the plate 1, and two lateral parts 15 and 16, profiled in L, which respectively form the slides 8 and 9. The vertical branches 15 a and 16 a of the two parts 15 and 16 are respectively adjacent to the lateral edges 17 and 18 of the upper part 14 of the sheet 13, which form an angle between them equal to that of the lateral edges 6 and 7 of the support 2 and which are respectively adjacent thereto. The horizontal branches 15 b and 16 b of the two parts 15 and 16 are oriented towards one another and support the support 2 laterally. Although this is not essential, but only preferable for better supporting the support 2, the sheet metal 13 may also include another part 19 L-shaped, the vertical branch 19 a of which adjoins the inner edge 21 of the upper part 14 of the sheet 13, and the horizontal branch 19 b of which extends below the inner edge 5 of the support 2 to support it as shown in Figures 2 and 3.

Les supports 2a, 2b, ... 2l peuvent être mis en place et fixés au plateau 1 de la manière suivante. Le support 2a est tout d'abord engagé dans les glissières 8 et 9 correspondantes par un mouvement radial dirigé vers le centre du plateau 1 et, lorsqu'il a été complètement engagé, une cheville 12 est introduite dans le trou 11 du support 2a. On effectue ensuite les mêmes opérations successivement avec les supports 2b, 2c... 2k. Après que la cheville 12 a été introduite dans le trou 11 du support 2k, le support 2l est engagé dans les glissières 8 et 9 correspondantes. Ensuite, une vis 22 (figures 1 et 2), est engagée à travers deux trous alignés, prévus respectivement dans le plateau 1 et dans la tôle 13 formant les deux glissières 8 et 9 du support 2l (l'un de ces deux trous est visible en 23 dans la figure 3), et la vis 22 est vissée dans un trou taraudé 24, aligné avec les deux trous précédents, du support 2l.The supports 2 a , 2 b , ... 2 l can be put in place and fixed to the tray 1 in the following manner. The support 2a is first of all engaged in the corresponding slides 8 and 9 by a radial movement directed towards the center of the plate 1 and, when it has been fully engaged, a pin 12 is introduced into the hole 11 of the support 2a. The same operations are then carried out successively with the supports 2 b , 2 c ... 2 k . After the pin 12 has been introduced into the hole 11 of the support 2 k , the support 2 l is engaged in the corresponding slides 8 and 9. Then, a screw 22 (Figures 1 and 2) is engaged through two aligned holes, provided respectively in the plate 1 and in the sheet 13 forming the two slides 8 and 9 of the support 2 l (one of these two holes is visible at 23 in FIG. 3), and the screw 22 is screwed into a tapped hole 24, aligned with the two preceding holes, of the support 2 l .

Une fois que le support 2l a été engagé dans la paire de glissières correspondantes 8 et 9 et que la vis 22 a été vissée dans le trou taraudé, on notera qu'aucune des chevilles 12 ne peut s'échapper du trou 11 du support correspondant, de sorte que tous les supports 2a, 2b... 2k sont positivement empêchés de s'échapper des paires de glissières correspondantes par les chevilles 12, le support 2l étant positivement empêché de s'échapper de sa propre paire de glissières par la vis 22. Le support 2l constitue donc en quelque sorte la clé de voute du système.Once the support 2 l has been engaged in the pair of corresponding slides 8 and 9 and the screw 22 has been screwed into the tapped hole, it will be noted that none of the pins 12 can escape from the hole 11 of the support corresponding, so that all the supports 2 a , 2 b ... 2 k are positively prevented from escaping from the pairs of corresponding slides by the pins 12, the support 2 l being positively prevented from escaping from its own pair of slides by the screw 22. The support 2 l therefore constitutes in a way the keystone of the system.

Pour enlever les supports 2a à 2l du plateau 1, il suffit de dévisser l'unique vis 22 pour retirer tout d'abord le support 2l en le faisant glisser radialement vers l'extérieur dans ses glissières 8 et 9. Ensuite, on extrait la cheville 12 du trou 11 du support 2k et on retire ce dernier en le faisant glisser radialement vers l'extérieur. On enlève ensuite successivement les supports 2g, 2i,... 2a en procédant de la même manière que pour le support 2k.To remove the supports 2 a to 2 l from the tray 1, simply unscrew the single screw 22 to first remove the support 2 l by sliding it radially outwards in its slides 8 and 9. Then, the pin 12 is extracted from the hole 11 in the support 2 k and the latter is removed by sliding it radially outwards. The supports 2 g , 2 i , ... 2 a are then successively removed in the same way as for the support 2 k .

D'après ce qui précède, il est clair que, en service, les supports 2a, 2b,...,2l sont maintenus positivement par rapport au plateau 1 par les chevilles 12 et par l'unique vis 22, et que leur montage et leur démontage peut être effectué très simplement et rapidement sans avoir à démonter le plateau 1 par rapport à son arbre d'entraînement.From the above, it is clear that, in service, the supports 2 a , 2 b , ..., 2 l are held positively relative to the plate 1 by the pins 12 and by the single screw 22, and that their assembly and disassembly can be done very simply and quickly without having to disassemble the plate 1 in relation to its drive shaft.

Dans le mode de réalisation représenté sur les figures 6 à 10, les éléments qui sont identiques ou qui jouent le même rôle que ceux des figures 1 à 5 sont désignés par les mêmes numéros de référence et ne seront pas décrits à nouveau en détail. Le mode de réalisation des figures 6 à 10 diffère de celui des figures 1 à 5 en ce que chacune des deux glissières 8 et 9 de chaque paire de glissières comporte un trou 25 ou 26 respectivement, qui est aligné avec le trou du support correspondant 2 lorsque celui-ci est complètement engagé dans la paire de glissières. Le montage et le démontage des supports 2a, 2b...2l du mode de réalisation des figures 6 à 10 s'effectuent dans le même ordre et de la même manière que ceux déjà décrits à propos des figures 1 à 5, excepté que, dans ce cas, chaque cheville d'arrêt 12 est introduite dans le trou 11 du support 2 correspondant, par exemple le support 2b de la figure 10, en faisant passer la cheville successivement à travers le trou 26 de la glissière 9 du support 2c non encore installé et à travers le trou 25 de la glissière 8 du support 2b.In the embodiment shown in Figures 6 to 10, the elements which are identical or which play the same role as those of Figures 1 to 5 are designated by the same reference numbers and will not be described again in detail. The embodiment of Figures 6 to 10 differs from that of Figures 1 to 5 in that each of the two slides 8 and 9 of each pair of slides has a hole 25 or 26 respectively, which is aligned with the hole of the corresponding support 2 when it is fully engaged in the pair of slides. The mounting and dismounting of the supports 2 a , 2 b ... 2 l of the embodiment of FIGS. 6 to 10 is carried out in the same order and in the same manner as those already described in connection with FIGS. 1 to 5, except that, in this case, each stop pin 12 is introduced into the hole 11 of the corresponding support 2, for example the support 2 b in FIG. 10, by passing the dowel successively through the hole 26 of the slide 9 of the support 2 c not yet installed and through the hole 25 of the slide 8 of the support 2b.

Comme montré dans la figure 10, un ressort de compression 27 peut être prévu dans le fond du trou 11 de chaque support 2 pour faciliter l'extraction de la cheville d'arrêt 12 hors du trou 11 lors du démontage des supports. Dans ce cas, après avoir introduit la cheville d'arrêt 12 dans le trou 11 du support correspondant, par exemple le support 2b de la figure 10, la cheville d'arrêt 12 est repoussée plus profondément à l'intérieur du trou 11, contre la force de rappel du ressort 27, par le support suivant, par exemple le support 2c, lorsque celui-ci est engagé dans la paire de glissières 8 et 9 correspondantes. Dans ce cas, l'angle entre le bord arrière 5 et le bord latéral 7 de chaque support 2 est de préférence arrondi ou biseauté comme montré en 28 dans la figure 8.As shown in FIG. 10, a compression spring 27 can be provided in the bottom of the hole 11 of each support 2 to facilitate the extraction of the stop pin 12 from the hole 11 during the disassembly of the supports. In this case, after having introduced the stop pin 12 into the hole 11 of the corresponding support, for example the support 2 b in FIG. 10, the stop pin 12 is pushed back deeper inside the hole 11, against the restoring force of the spring 27, by the following support, for example the support 2 c , when the latter is engaged in the pair of corresponding slides 8 and 9. In this case, the angle between the rear edge 5 and the lateral edge 7 of each support 2 is preferably rounded or bevelled as shown at 28 in FIG. 8.

Il va de soi que les formes d'exécution de la présente invention qui ont été décrites ci-dessus ont été données à titre d'exemple purement indicatif et nullement limitatif, et que de nombreuses modifications peuvent être facilement apportées par l'homme de l'art, sans pour autant sortir du cadre de la présente invention.It goes without saying that the embodiments of the present invention which have been described above have been given to purely by way of example and in no way limitative, and that numerous modifications can be easily made by those skilled in the art, without going beyond the ambit of the present invention.
