Description

La présente invention concerne une machine pour la mise en état et/ou l'entretien de surfaces, et plus particulièrement de sols.The present invention relates to a machine for preparing and / or maintaining surfaces, and more particularly floors.

On connaît déjà, notamment par les brevets GB-A-1 083 775 et US-A-3 464 075, une telle machine, comportant un moteur susceptible d'entraîner en rotation au moins un outil rotatif par l'intermédiaire d'un arbre d'entraînement au moins sensiblement orthogonal audit outil, ledit outil étant relié audit arbre d'entraînement par un disque d'entraînement relié, au voisinage de sa périphérie externe, à l'outil et, au voisinage de son centre, à l'arbre d'entraînement, et permettant une inclinaison relative d'amplitude limitée de l'axe de rotation de l'outil par rapport audit arbre d'entraînement. Cependant, dans ces machines connues, ledit disque est réalisé en une matière élastique (métal ou caoutchouc) , de sorte que le degré de liberté de l'outil parallèlement à l'axe de l'outil est limité par l'élasticité du disque et qu'il en résulte des défauts de coplanarité de l'outil par rapport au sol. Par suite, la surface traitée est attaquée irrégulièrement par ledit outil, de sorte qu'elle ne peut être parfaitement uniforme.Already known, in particular from patents GB-A-1 083 775 and US-A-3 464 075, such a machine, comprising a motor capable of driving in rotation at least one rotary tool by means of a shaft at least substantially orthogonal to said tool, said tool being connected to said drive shaft by a drive disc connected, near its external periphery, to the tool and, near its center, to the shaft drive, and allowing a relative inclination of limited amplitude of the axis of rotation of the tool relative to said drive shaft. However, in these known machines, said disc is made of an elastic material (metal or rubber), so that the degree of freedom of the tool parallel to the axis of the tool is limited by the elasticity of the disc and that this results in defects in the coplanarity of the tool with respect to the ground. As a result, the treated surface is irregularly attacked by said tool, so that it cannot be perfectly uniform.

La présente invention a pour but de perfectionner une machine du type défini ci-dessus.The present invention aims to improve a machine of the type defined above.

A cet effet, la machine pour la mise en état et/ou l'entretien des sols, du type indiqué précédemment, est remarquable, selon l'invention, en ce que ledit disque d'entraînement est réalisé en une matière qui est souple perpendiculairement à son plan, mais qui est rigide dans son plan et en ce que ledit disque d'entraînement est monté, entre ledit outil et ledit arbre d'entraînement, de façon à former radialement au moins une ondulation autour dudit axe de l'outil lorsque la machine repose sur ledit outil et que l'axe dudit outil est coaxial à celui dudit arbre d'entraînement.To this end, the machine for preparing and / or maintaining floors, of the type indicated above, is remarkable, according to the invention, in that said drive disc is made of a material which is flexible perpendicularly to its plane, but which is rigid in its plane and in that said drive disc is mounted, between said tool and said drive shaft, so as to form at least one ripple radially around said axis of the tool when the machine rests on said tool and the axis of said tool is coaxial with that of said drive shaft.

Puisque la matière dudit disque d'entraînement est rigide dans son plan, le disque peut transmettre le couple de l'arbre d'entraînement audit outil, de sorte que celui-ci est entraîné en rotation. Par ailleurs, puisque la matière du disque d'entraînement est souple perpendiculairement à son plan, la ou les ondulations constituent un excédent de matière parallèlement à l'axe de l'outil.Since the material of said drive disc is rigid in its plane, the disc can transmit the torque from the drive shaft to said tool, so that the latter is rotated. Furthermore, since the material of the drive disc is flexible perpendicular to its plane, the undulation or undulations constitute an excess of material parallel to the axis of the tool.

Ainsi, un tel organe de liaison permet, notamment au démarrage, un "découplage" de l'outil du restant de la machine, facilitant la mise en route de l'outil, et le maintien de ce dernier de façon parfaitement parallèle au sol à traiter, pendant le traitement. De plus, comme on le verra ci-après, l'organe de liaison, tel que défini ci-dessus, autorise une répartition d'efforts ou de forces sur l'outil, qui permet un déplacement latéral de la machine.Thus, such a connecting member allows, in particular at startup, a "decoupling" of the tool from the rest of the machine, facilitating the start-up of the tool, and the maintenance of the latter in a manner perfectly parallel to the ground at treat, during treatment. In addition, as will be seen below, the connecting member, as defined above, allows a distribution of forces or forces on the tool, which allows lateral movement of the machine.

Avantageusement, ledit disque d'entraînement est constitué d'une toile de matière synthétique rigide en cisaillement de rotation. Une telle toile peut par exemple être du type de celles utilisées pour la réalisation de bandes transporteuses. Elle peut être constituée de tissus croisés en fibres polyester enrobés de chlorure de polyvinyle.Advantageously, said drive disc consists of a canvas of rigid synthetic material in rotational shear. Such a fabric can for example be of the type used for the production of conveyor belts. It can be made of crossover fabrics made of polyester fibers coated with polyvinyl chloride.

Dans le cas où ledit disque est solidaire, au voisinage de son centre, d'une collerette solidaire dudit axe d'entraînement, il est avantageux que, par inclinaison relative de l'axe dudit arbre d'entraînement par rapport à l'axe de rotation dudit outil, la périphérie externe de ladite collerette puisse presser localement ledit outil contre le sol. Ainsi, à l'aplomb de cette pression locale, le frottement de l'outil sur le sol est plus élevé qu'ailleurs, de sorte que, du fait de la rotation de l'outil, il en résulte un déplacement spontané de la machine par rapport au sol traité. En choisissant l'emplacement de cette pression locale, on détermine la direction du déplacement spontané.In the case where said disc is integral, near its center, with a collar integral with said drive axis, it is advantageous that, by relative inclination of the axis of said drive shaft relative to the axis of rotation of said tool, the outer periphery of said collar can locally press said tool against the ground. Thus, below this local pressure, the friction of the tool on the ground is higher than elsewhere, so that, due to the rotation of the tool, this results in a spontaneous movement of the machine. compared to the treated soil. By choosing the location of this local pressure, the direction of the spontaneous movement is determined.

Pour faciliter une telle inclinaison susceptible d'engendrer un tel déplacement spontané, il est préférable que l'arbre d'entraînement de la machine soit monté sur un joint à la Cardan et qu'une tringlerie agissant sur le joint à la Cardan soit prévue pour commander l'inclinaison relative entre l'arbre d'entraînement et l'axe de rotation de l'outil.To facilitate such an inclination likely to generate such spontaneous displacement, it is preferable that the machine drive shaft is mounted on a universal joint and that a linkage acting on the universal joint is provided for control the relative inclination between the drive shaft and the axis of rotation of the tool.

Selon une autre caractéristique de l'invention, la machine comprend des moyens spécifiques pour exercer une pression locale sur ledit outil en direction du sol.According to another characteristic of the invention, the machine comprises specific means for exerting local pressure on said tool in the direction of the ground.

De préférence, lesdits moyens de pression spécifiques comportent une pièce en forme de disque présentant un rebord à sa périphérie externe, tourné vers ledit disque d'entraînement et susceptible de s'appliquer localement sur ce dernier par une portion de son périmètre. Lesdits moyens de pression spécifiques peuvent, en variante, comporter une pièce en forme de disque, dont la face tournée vers le disque présente, en section transversale, un profil convexe. Ce profil convexe permet de faire varier radialement le point d'application desdits moyens de pression sur le disque d'entraînement, de façon à augmenter ou diminuer la vitesse de déplacement latéral de la machine.Preferably, said specific pressure means comprise a disc-shaped part having a rim at its external periphery, facing towards said drive disc and capable of being applied locally to the latter by a portion of its perimeter. Said specific pressure means may, as a variant, comprise a disc-shaped part, the face of which facing the disc has, in cross section, a convex profile. This convex profile makes it possible to radially vary the point of application of said pressure means on the drive disc, so as to increase or decrease the speed of lateral movement of the machine.

De plus, en son centre, ledit disque de pression peut présenter un arbre creux traversé par l'arbre d'entraînement.In addition, at its center, said pressure disc may have a hollow shaft through which the drive shaft passes.

Par ailleurs, ledit arbre creux peut être monté, par l'intermédiaire d'un roulement, dans une bague solidaire d'une tringlerie de commande.Furthermore, said hollow shaft can be mounted, by means of a bearing, in a ring integral with a control linkage.

Avantageusement, ladite tringlerie comporte une première bielle s'étendant le long d'un mancheron, articulée à une seconde bielle en forme générale de fourche.Advantageously, said linkage comprises a first connecting rod extending along a handlebar, articulated to a second connecting rod in the general shape of a fork.

De préférence, ladite seconde bielle présente deux branches dont les extrémités libres respectives sont articulées de part et d'autre des moyens de pression.Preferably, said second connecting rod has two branches, the respective free ends of which are articulated on either side of the pressure means.

En plus, l'invention concerne un disque d'entraînement selon la revendication 12.In addition, the invention relates to a drive disc according to claim 12.

La figure 12 est une vue en coupe longitudinale partielle d'une variante du troisième exemple de réalisation de la machine selon l'invention, illustré par les figures 8 à 11.FIG. 12 is a view in partial longitudinal section of a variant of the third embodiment of the machine according to the invention, illustrated by FIGS. 8 to 11.

La figure 13 est une vue semblable à la figure 12, montrant l'application des moyens spécifiques de pression sur l'organe de liaison.Figure 13 is a view similar to Figure 12, showing the application of specific pressure means on the connecting member.

La machine 1 de l'invention, selon l'exemple de réalisation montré sur les figures 1 et 2, dans lequel la machine est dépourvue de moyens de roulement, comporte un châssis 2 sur lequel est monté un moteur 3, relié à un mancheron 4 permettant à l'opérateur de manoeuvrer la machine. En particulier, le mancheron 4 peut être équipé de poignées et d'organes de commande (non représentés).The machine 1 of the invention, according to the exemplary embodiment shown in FIGS. 1 and 2, in which the machine is devoid of rolling means, comprises a frame 2 on which is mounted a motor 3, connected to a handle 4 allowing the operator to maneuver the machine. In particular, the handle 4 can be equipped with handles and control members (not shown).

Le moteur 3 est susceptible d'entraîner en rotation un outil rotatif 5 pouvant être, par exemple, équipé d'une brosse 6, ou de tout autre moyen approprié tel que meule, tampon en matière fibreuse ou abrasive pour la mise en état, le nettoyage et/ou l'entretien d'un sol G, et cela par l'intermédiaire d'un arbre d'entraînement 7, tournant autour de l'axe 8, au moins sensiblement orthogonal à l'outil 5.The motor 3 is capable of driving in rotation a rotary tool 5 which can be, for example, equipped with a brush 6, or any other suitable means such as a grinding wheel, a pad made of fibrous or abrasive material for conditioning, cleaning and / or maintenance of a floor G, and this by means of a drive shaft 7, rotating around the axis 8, at least substantially orthogonal to the tool 5.

Par ailleurs, l'outil 5 est relié à l'arbre d'entraînement 7 par un disque d'entraînement 9 réalisé en une matière qui est souple perpendiculairement à son plan, mais qui est rigide dans son plan. Le disque d'entraînement 9 est relié, au voisinage de sa périphérie externe, à l'outil 5, par des moyens de fixation appropriés 10, tels que rivets, boulons ou analogues, et, au voisinage de son centre, à une collerette 7A solidaire de l'arbre d'entraînement 7, également par des moyens de fixation appropriés 11, tels que rivets, boulons ou analogues.Furthermore, the tool 5 is connected to the drive shaft 7 by a drive disc 9 made of a material which is flexible perpendicular to its plane, but which is rigid in its plane. The drive disc 9 is connected, in the vicinity of its external periphery, to the tool 5, by suitable fixing means 10, such as rivets, bolts or the like, and, in the vicinity of its center, to a flange 7A integral with the drive shaft 7, also by suitable fixing means 11, such as rivets, bolts or the like.

Comme montré sur la figure 1, le disque d'entraînement 9, qui peut être constitué d'une toile de matière synthétique rigide en cisaillement de rotation, est monté de façon à former radialement au moins une ondulation 9A autour de l'axe 12 de l'outil 5, lorsque ladite machine repose sur ledit outil et que l'axe 12 de celui-ci est coaxial à l'axe 8 de l'arbre d'entraînement 7. Ainsi, une telle ondulation permet une liaison lâche limitée entre la collerette 7A et l'outil 5, parallèlement aux axes 8 et 12.As shown in FIG. 1, the drive disc 9, which may consist of a canvas of rigid synthetic material in rotational shear, is mounted so as to form radially at least one corrugation 9A around the axis 12 of the tool 5, when the said machine rests on the said tool and the axis 12 thereof is coaxial with the axis 8 of the drive shaft 7. Thus, such an undulation allows a loose connection limited between the flange 7A and the tool 5, parallel to the axes 8 and 12.

Ainsi, un tel disque ondulé 9 permet, au démarrage, un "découplage" de l'outil du restant de la machine par soulèvement de celle-ci, facilitant la mise en rotation de l'outil, et le maintien de l'outil de façon parfaitement parallèle au sol à traiter.Thus, such a corrugated disc 9 allows, at startup, a "decoupling" of the tool from the rest of the machine by lifting it, facilitating the rotation of the tool, and the maintenance of the tool. perfectly parallel to the soil to be treated.

Comme montré sur la figure 2, le disque d'entrainement 9, ainsi monté, permet de plus une inclinaison relative entre l'axe de rotation 12 de l'outil 5 et l'arbre d'entraînement 7, ce qui, associé aux caractéristiques structurelles indiquées ci-dessus du disque 9, autorise, lorsque la collerette 7A presse localement en 7B l'outil 5 contre le sol G, une répartition d'efforts ou de forces F sur l'outil 5, telle que montrée sur la figure 3, permettant en combinaison avec la rotation dudit outil un déplacement latéral spontané de la machine (sur la figure 3, la longueur des flèches F est proportionnelle à l'intensité des forces appliquées). Bien entendu, la direction de ce déplacement latéral spontané dépend de la position du point 7B autour de l'axe 12. On peut donc déplacer la machine 1, sans effort, dans toute direction désirée, en choisissant le point d'application 7B de la pression locale.As shown in Figure 2, the drive disc 9, thus mounted, further allows a relative inclination between the axis of rotation 12 of the tool 5 and the drive shaft 7, which, associated with the characteristics above indicated of the disc 9, when the collar 7A locally presses the tool 5 against the ground G, a distribution of forces or forces F on the tool 5, as shown in FIG. 3 , allowing in combination with the rotation of said tool a spontaneous lateral movement of the machine (in FIG. 3, the length of the arrows F is proportional to the intensity of the forces applied). Of course, the direction of this spontaneous lateral movement depends on the position of the point 7B around the axis 12. It is therefore possible to move the machine 1, without effort, in any desired direction, by choosing the point of application 7B of the local pressure.

L'exemple de réalisation de la machine de l'invention, illustré par les figures 6 à 7, comprend généralement les mêmes éléments, ou des éléments analogues, que la machine des figures 1 et 2, en particulier le disque d'entraînement 9 reliant l'outil 5 à l'arbre d'entraînement 7, et, de plus, des moyens de roulement non représentés.The embodiment of the machine of the invention, illustrated by FIGS. 6 to 7, generally comprises the same elements, or similar elements, as the machine in FIGS. 1 and 2, in particular the drive disc 9 connecting the tool 5 to the drive shaft 7, and, in addition, rolling means not shown.

Par ailleurs, dans ce cas, l'arbre d'entraînement 7 est monté sur un joint à la Cardan 14, relié au châssis 2, dont le rôle est d'assurer un encore meilleur parallélisme de l'outil par rapport au sol. L'inclinaison du joint à la Cardan 14 et, ainsi, de l'arbre d'entraînement 7, par rapport à l'axe de rotation 12 de l'outil 5, est commandée par une tringlerie 15. Une couronne souple 16 garantit l'étanchéité entre l'arbre d'entraînement 7 et l'outil 5.Furthermore, in this case, the drive shaft 7 is mounted on a universal joint 14, connected to the chassis 2, the role of which is to ensure an even better parallelism of the tool with respect to the ground. The inclination of the joint to the gimbal 14 and, thus, of the drive shaft 7, relative to the axis of rotation 12 of the tool 5, is controlled by a linkage 15. A flexible crown 16 guarantees the sealing between the drive shaft 7 and the tool 5.

Dans l'exemple de réalisation des figures 8 à 11, la machine 1 comporte, à nouveau, un châssis 2, sur lequel est monté un moteur 3, relié à un mancheron 4 équipé de poignées 4a et d'organes de commande 4b. La machine 1 est munie de moyens de roulement portant la référence 40, comportant deux roues agencées à l'arrière de la machine.In the embodiment of Figures 8 to 11, the machine 1 again comprises a frame 2, on which is mounted a motor 3, connected to a handle 4 equipped with handles 4a and control members 4b. The machine 1 is provided with rolling means bearing the reference 40, comprising two wheels arranged at the rear of the machine.

Comme précédemment, le moteur 3 est susceptible d'entraîner en rotation un outil rotatif 5, muni d'une brosse 6 ou analogue, par l'intermédiaire d'un arbre d'entraînement 7, tournant autour de l'axe 8 orthogonal à l'outil 5.As before, the motor 3 is capable of driving in rotation a rotary tool 5, provided with a brush 6 or the like, by means of a drive shaft 7, rotating around the axis 8 orthogonal to the tool 5.

Plus précisément, l'arbre du moteur 3 d'axe de rotation 20 porte, à son extrémité libre, une poulie 21 reliée à une poulie 22, portée par l'arbre d'entraînement 7, par une courroie 23.More precisely, the shaft of the motor 3 with an axis of rotation 20 carries, at its free end, a pulley 21 connected to a pulley 22, carried by the drive shaft 7, by a belt 23.

Egalement dans ce cas, l'outil 5 est relié à l'arbre d'entrainement 7 par un disque d'entraînement 9 possédant les caractéristiques déjà décrites. En particulier, le disque 9 peut être réalisé sous forme de toile (comme représenté).Also in this case, the tool 5 is connected to the drive shaft 7 by a drive disc 9 having the characteristics already described. In particular, the disc 9 can be produced in the form of a canvas (as shown).

Le disque d'entraînement 9 est relié, au voisinage de sa périphérie externe, à l'outil 5, et, au voisinage de son centre, à l'arbre d'entraînement 7, par des moyens de fixation appropriés 10 et 11, respectivement.The drive disc 9 is connected, in the vicinity of its external periphery, to the tool 5, and, in the vicinity of its center, to the drive shaft 7, by suitable fixing means 10 and 11, respectively .

Par ailleurs, dans ce cas, on prévoit des moyens spécifiques 24 pour exercer une pression locale sur le disque d'entraînement 9, permettant de renforcer l'effet de déplacement latéral, moyens 24 qui sont actionnés par une tringlerie 25 dont l'extrémité libre 25a est fixée au mancheron 4 au voisinage des poignées 4a, pour sa commande par l'opérateur. Comme on peut mieux le voir sur la figure 11, ces moyens 24 comprennent une pièce 26 en forme de disque présentant un rebord 27 à sa périphérie externe, tourné vers le disque d'entraînement 9 et destiné à s'appliquer sur ce dernier par une portion de son périmètre, en n'importe quel point du disque d'entraînement 9 autour de l'arbre d'entraînement 7, l'application ayant lieu au voisinage dudit arbre d'entraînement 7.Furthermore, in this case, specific means 24 are provided for exerting local pressure on the drive disc 9, making it possible to reinforce the effect of lateral displacement, means 24 which are actuated by a linkage 25 whose free end 25a is fixed to the handle 4 in the vicinity of the handles 4a, for its control by the operator. As can best be seen in FIG. 11, these means 24 comprise a disc-shaped part 26 having a flange 27 at its outer periphery, facing the drive disc 9 and intended to be applied to the latter by a portion of its perimeter, at any point of the drive disc 9 around the drive shaft 7, the application taking place in the vicinity of said drive shaft 7.

En son centre, le disque 26 présente un arbre creux 28 traversé par l'arbre 7 reliée à la poulie 22. L'arbre creux 28 est monté, par l'intermédiaire d'un roulement 29, dans une bague 30 solidaire de la tringlerie 25.In its center, the disc 26 has a hollow shaft 28 crossed by the shaft 7 connected to the pulley 22. The hollow shaft 28 is mounted, by means of a bearing 29, in a ring 30 integral with the linkage 25.

La tringlerie 25 comporte une première bielle 31 s'étendant le long du mancheron 4, articulée en 32 à une seconde bielle en forme générale de fourche 33 présentant deux branches 33a, 33b dont les extrémités libres respectives sont articulées de part et d'autre des moyens de pression 24, pour commander l'inclinaison de ces derniers.The linkage 25 comprises a first connecting rod 31 extending along the handle 4, articulated at 32 to a second connecting rod in the general shape of a fork 33 having two branches 33a, 33b whose respective free ends are articulated on either side of the pressure means 24 for controlling the inclination of the latter.

La variante de réalisation de la machine des figures 12 et 13 comporte généralement les mêmes éléments constitutifs que la machine montrée sur les figures 8 à 11. Cependant, les moyens spécifiques 24 pour exercer une pression locale sur le disque d'entraînement 9 présentent une structure quelque peu différente. En effet, dans ce cas, ces moyens 24 comprennent également une pièce 26 en forme de disque mais dont la face 50 tournée vers le disque d'entraînement 9 présente, en section transversale, un profil convexe, de façon à faire varier radialement le point d'application desdits moyens de pression 24 sur le disque d'entraînement 9, en permettant, ainsi, d'augmenter ou de diminuer la vitesse latérale de la machine. Cette variation du point d'application s'obtient en faisant pivoter le mancheron 4 autour de l'articulation 51, comme l'illustre la double flèche 52.The variant embodiment of the machine in FIGS. 12 and 13 generally comprises the same elements constitutive as the machine shown in Figures 8 to 11. However, the specific means 24 for exerting local pressure on the drive disc 9 have a somewhat different structure. Indeed, in this case, these means 24 also comprise a part 26 in the form of a disc but whose face 50 facing the drive disc 9 has, in cross section, a convex profile, so as to vary the point radially. applying said pressure means 24 to the drive disc 9, thereby making it possible to increase or decrease the lateral speed of the machine. This variation of the point of application is obtained by rotating the handle 4 around the joint 51, as illustrated by the double arrow 52.

Comme dans la réalisation des figures 8 à 11, le disque de pression 26 présente, en son centre, un arbre creux 28 traversé par l'arbre 7 relié à la poulie 22. L'arbre creux 28 est monté, par l'intermédiaire d'un roulement 29, dans une bague 30 solidaire de la tringlerie 25.As in the embodiment of FIGS. 8 to 11, the pressure disc 26 has, at its center, a hollow shaft 28 crossed by the shaft 7 connected to the pulley 22. The hollow shaft 28 is mounted, by means of 'A bearing 29, in a ring 30 integral with the linkage 25.

En comparant les figures 1, 2 et 5 à 8, d'une part, et les figures 11 à 13, d'autre part, on peut remarquer que, suivant que l'outil 5 comporte ou non un évidement central 5A et que la collerette 7A pénètre ou non à l'intérieur dudit évidement central 5A, la ou les ondulations 9A formées par l'excédent de matière du disque d'entraînement 9 se forment à des endroits radialement différents.By comparing FIGS. 1, 2 and 5 to 8, on the one hand, and FIGS. 11 to 13, on the other hand, it can be noted that, depending on whether the tool 5 includes or not a central recess 5A and that the flange 7A penetrates or not inside said central recess 5A, the corrugation (s) 9A formed by the excess material of the drive disc 9 are formed at radially different places.
