Description

La présente invention concerne une machine pour la mise en état et/ou l'entretien des sols.The present invention relates to a machine for preparing and / or maintaining floors.

On connaît déjà une telle machine comportant un châssis, éventuellement monté sur roues et supportant un moteur entraînant en rotation au moins un outil rotatif, tel qu'une brosse, un disque abrasif, etc..., au moins un mancheron étant prévu pour déplacer et/ou contrôler le déplacement de ladite machine.Such a machine is already known comprising a chassis, possibly mounted on wheels and supporting a motor driving in rotation at least one rotary tool, such as a brush, an abrasive disc, etc., at least one handle being provided for moving and / or control the movement of said machine.

Dans une telle machine connue, il est fréquent de ne prévoir qu'un seul essieu transversal au châssis et pourvu d'une roue à chacune de ses extrémités, tandis que l'outil rotatif est assujetti à tourner autour d'un axe fixe orthogonal au châssis. Aussi du fait que ce châssis peut pivoter autour dudit essieu et que l'organe rotatif s'use en fonctionnement, il est fréquent que ledit outil, au lieu de bien s'appliquer à plat sur le sol à nettoyer ou à faire briller, attaque ledit sol soit de son extrémité avant, soit de son extrémité arrière, ce qui nuit à la qualité du travail effectué et peut même détériorer le sol.In such a known machine, it is common to provide only one axle transverse to the chassis and provided with a wheel at each of its ends, while the rotary tool is subject to rotate around a fixed axis orthogonal to the frame. Also the fact that this chassis can pivot around said axle and that the rotary member wears out in operation, it is frequent that said tool, instead of being applied flat on the ground to be cleaned or made to shine, attacks said floor either from its front end or from its rear end, which affects the quality of the work carried out and may even deteriorate the floor.

La présente invention a pour objet de remédier à ces inconvénients.The object of the present invention is to remedy these drawbacks.

A cette fin, selon l'invention, la machine pour la mise en état et/ou l'entretien des sols comportant un châssis éventuellement monté sur roues et supportant un moteur entraînant en rotation au moins un outil rotatif, tel qu'une brosse ou un disque, autour d'un axe orthogonal audit châssis, au moins un mancheron étant prévu pour déplacer et/ou contrôler le déplacement de ladite machine, est remarquable en ce que le ou au moins certains des outils rotatifs sont montés sur leurs axes respectifs par l'intermédiaire d'un joint à la Cardan.To this end, according to the invention, the machine for preparing and / or maintaining floors comprising a chassis possibly mounted on wheels and supporting a motor driving in rotation at least one rotary tool, such as a brush or a disc, around an axis orthogonal to said chassis, at least one handle being provided for moving and / or controlling the movement of said machine, is remarkable in that the or at least some of the rotary tools are mounted on their respective axes by through a Cardan joint.

Ainsi, quelles que soient les variations d'inclinaison du bâti par rapport au sol, et les variations d'épaisseur des outils au cours de leur utilisation, ces outils peuvent continuellement rester appliqués à plat contre le sol.Thus, whatever the variations in inclination of the frame relative to the ground, and the variations in thickness of the tools during use, these tools can continually remain flat against the ground.

Dans le cas où ledit châssis est porté par deux roues alignées, selon un axe transversal et excentré par rapport à l'axe de rotation dudit outil, il est avantageux que lesdites roues soient montées réglables de sorte que leur axe commun puisse être rapproché ou éloigné dudit axe de rotation de l'outil. Ainsi, on obtient une possibilité de réglage supplémentaire en fonction de l'épaisseur dudit outil, ainsi qu'un moyen de réglage de la pression exercée par l'outil sur le sol.In the case where said chassis is carried by two aligned wheels, along a transverse axis and eccentric relative to the axis of rotation of said tool, it is advantageous that said wheels are mounted adjustable so that their common axis can be brought closer or further apart of said axis of rotation of the tool. Thus, there is obtained a possibility of additional adjustment as a function of the thickness of said tool, as well as a means of adjusting the pressure exerted by the tool on the ground.

Les roues supportant le bâti peuvent être rigidement montées autour d'un axe orthogonal à l'axe de rotation de l'outil. Cependant, afin de pouvoir faciliter des déplacements latéraux de la machine, ces roues peuvent en variante être montées librement rotatives autour d'un axe parallèle à l'axe de rotation de l'outil, pour pouvoir s'orienter spontanément. Enfin, le nombre de ces roues n'est pas limité à deux. De plus, la machine selon l'invention peut ne pas comporter de roues, son poids reposant sur le sol par l'intermédiaire des outils .The wheels supporting the frame can be rigidly mounted around an axis orthogonal to the axis of rotation of the tool. However, in order to be able to facilitate lateral movements of the machine, these wheels can alternatively be mounted freely rotating around an axis parallel to the axis of rotation of the tool, in order to be able to orient themselves spontaneously. Finally, the number of these wheels is not limited to two. In addition, the machine according to the invention may not have wheels, its weight resting on the ground by means of the tools.

Les outils connus (disques, abrasifs, brosses etc...) utilisés sur les machines connues sont montés sur une armature rigide, généralement en bois. Selon une autre particularité de l'invention, afin d'améliorer encore la faculté d'application de l'outil sur le sol, l'outil peut comporter une armature élastique souple, par exemple un disque de tôle à ressort précontraint, pressant ledit outil en direction du sol à l'encontre de la réaction du sol sur ledit outil.Known tools (discs, abrasives, brushes, etc.) used on known machines are mounted on a rigid frame, generally made of wood. According to another feature of the invention, in order to further improve the ability of the tool to be applied to the ground, the tool may include a flexible elastic frame, for example a disc of pre-stressed spring sheet metal, pressing said tool towards the ground against the reaction of the ground on said tool.

La machine du type selon l'invention, montrée par la figure 1, comporte un châssis 1 sur lequel est monté un moteur électrique 2 dont l'axe est orthogonal audit châssis. Deux roues 3 sont disposées de part et d'autre du châssis 1, à une extrémité de celui-ci. Par ailleurs, un mancheron 4 équipé d'une poignée 5 et d'organes de manoeuvre 6 est relié au châssis 1, du côté de celui-ci où sont disposées les roues 3.The machine of the type according to the invention, shown in Figure 1, comprises a chassis 1 on which is mounted an electric motor 2 whose axis is orthogonal to said chassis. Two wheels 3 are arranged on either side of the chassis 1, at one end of the latter. In addition, a handlebar 4 equipped with a handle 5 and operating members 6 is connected to the chassis 1, on the side thereof where the wheels 3 are arranged.

A l'extrémité du châssis 1, opposée aux roues 3 et au mancheron 4, la machine comporte un outil rotatif 7 tel qu'une brosse ou un disque abrasif, éventuellement partiellement ou totalement enveloppé par un capot de protection.At the end of the chassis 1, opposite the wheels 3 and the handle 4, the machine comprises a rotary tool 7 such as a brush or an abrasive disc, possibly partially or totally enveloped by a protective cover.

Le moteur 2 entraîne en rotation une poulie 8, qui elle-même par l'intermédiaire d'une ou plusieurs courroies plates ou trapézoïdales 9 entraîne en rotation une poulie 10 montée sur un arbre 11 d'axe orthogonal au bâti 1 et donc parallèle à l'axe du moteur 2.The motor 2 rotates a pulley 8, which itself by means of one or more flat or trapezoidal belts 9 rotates a pulley 10 mounted on a shaft 11 of axis orthogonal to the frame 1 and therefore parallel to motor axis 2.

Selon l'invention, l'outil 7 est monté sur l'arbre 11 par l'intermédiaire d'un joint à la Cardan 12. Ainsi, que le bâti 1 soit parallèle au sol (voir les figures 2 et 3) ou incliné par rapport au sol (voir la figure 4), l'outil 7 reste toujours appliqué à plat sur le sol, ce qui permet de plus de compenser les variations d'épaisseur de l'outil 7 (usure, changement d'outils, etc...).According to the invention, the tool 7 is mounted on the shaft 11 by means of a universal joint 12. Thus, that the frame 1 is parallel to the ground (see Figures 2 and 3) or inclined by relative to the ground (see FIG. 4), the tool 7 always remains applied flat on the ground, which also makes it possible to compensate for variations in thickness of the tool 7 (wear, change of tools, etc. ..).

Comme le montre la figure 5, les roues 3 peuvent être montées réglables par rapport au bâti 1 de façon à ce que leur distance à l'arbre 11 soit réglable. Sur la figure 5, on a représenté un système à lumières oblongues 13 et à vis 14, mais il va de soi que la présente invention n'est pas limitée à ce mode de réalisation.De même, sur les figures on n'a représenté que deux roues 3 montées rigidement sur leur moyeu, mais il va de soi que la présente invention n'est pas limitée à ce nombre de roues et que lesdites roues peuvent de plus être montées spontanément orientables autour d'un axe parallèle à l'axe 11.As shown in Figure 5, the wheels 3 can be mounted adjustable relative to the frame 1 so that their distance to the shaft 11 is adjustable. In FIG. 5, an oblong lumen system 13 and a screw 14 are shown, but it goes without saying that the present invention is not limited to this embodiment. Likewise, in the figures, only FIG. that two wheels 3 rigidly mounted on their hub, but it goes without saying that the present invention is not limited to this number of wheels and that said wheels can moreover be mounted spontaneously orientable around an axis parallel to the axis 11.

Eventuellement, notamment dans le cas où l'outil 7 est un outil de ponçage, on peut prévoir un capot enveloppant relié par une tubulure 16 à un sac 17 porté par le mancheron 4. Ainsi, la poussière engendrée par l'outil 7 peut être aspirée et stockée dans le sac 17.Optionally, in particular in the case where the tool 7 is a sanding tool, one can provide an enveloping cover connected by a tube 16 to a bag 17 carried by the handle 4. Thus, the dust generated by the tool 7 can be sucked up and stored in the bag 17.

Sur la figure 4, on a représenté un mode de réalisation particulièrement adapté à la machine de la présente invention. A cette fin, le bâti 1 est entouré par une jupe souple 18 prenant appui sur le sol au moyen de picots espacés 19. Ainsi, la jupe 18 peut s'adapter aux différentes inclinaisons du châssis 1, tout en enveloppant correctement l'outil de ponçage 7 afin que l'aspiration à travers la tubulure 16 soit efficace.In Figure 4, there is shown an embodiment particularly suitable for the machine of the present invention. To this end, the frame 1 is surrounded by a flexible skirt 18 bearing on the ground by means of spaced pins 19. Thus, the skirt 18 can adapt to the different inclinations of the chassis 1, while correctly wrapping the tool sanding 7 so that the suction through the tubing 16 is effective.

Dans les modes de réalisation des figures 2 et 3, on a représenté des outils 7 de type connu, comportant une armature rigide de bois 7a. En revanche, dans le mode de réalisation de la figure 4, l'outil 7 est monté sur une armature 7b, souple et élastique, éventuellement précontrainte en direction du sol, pour permettre une meilleure application de l'outil sur celui-ci.In the embodiments of Figures 2 and 3, there is shown tools 7 of known type, comprising a rigid wooden frame 7a. On the other hand, in the mode of realization tion of Figure 4, the tool 7 is mounted on a frame 7b, flexible and elastic, possibly prestressed in the direction of the ground, to allow better application of the tool thereon.

Dans le cas où la machine est pourvue de roues pivotantes, ou bien encore lorsqu'elle est dépourvue de roues et repose sur le sol par l'intermédiaire de ses outils, il peut être avantageux de prévoir des moyens pour exercer une pression variable commandée sur au moins l'un de ses outils. Ainsi, on contrôle facilement les déplacements latéraux de la machine.In the case where the machine is provided with swivel wheels, or even when it is devoid of wheels and rests on the ground by means of its tools, it may be advantageous to provide means for exerting a controlled variable pressure on at least one of its tools. Thus, the lateral movements of the machine are easily controlled.

De tels moyens peuvent être constitués par une roulette de pression 20 roulant sur l'un desdits outils et commandée à partir du mancheron, par l'intermédiaire d'un câble ou analogue 21, ou bien encore par un électro-aimant, etc...Such means can be constituted by a pressure roller 20 rolling on one of said tools and controlled from the handle, by means of a cable or the like 21, or even by an electromagnet, etc. .
