L'invention se rattache au secteur technique du matériel d'équipement roulant mis à la disposition de l'utilisateur pour effectuer des opérations de ponçage, surfaçage, meulage, sur parois de murs, plafonds et similaires.The invention relates to the technical field of rolling stock equipment made available to the user for sanding, surfacing, grinding, wall walls, ceilings and the like.

Le Demandeur s'est intéressé depuis de nombreuses années à mettre à disposition du matériel et des équipements autonomes qui facilitent le travail des opérateurs lors des opérations d'entretien et de rénovation de murs et plafonds de construction et aussi lors des opérations de finitions de ceux-ci. Ainsi, le Demandeur a conçu et développé des chariots-desserte en vue des applications précitées. Ces chariots-dessertes incluent une ou plusieurs ponceuses à bras, un bloc aspirateur et offrent l'autonomie nécessaire d'utilisation pour l'opérateur. Ces chariots-dessertes sont agencés pour permettre le rangement et le maintien en position verticale de la ou des ponceuses à bras mais aussi leur enlèvement pour permettre ensuite d'effectuer les travaux auxquels elles sont destinées. Dans le cadre des solutions proposées, le Demandeur a aussi prévu de pouvoir orienter en position grâce à des supports appropriés le positionnement, l'articulation et l'orientation de la ou les ponceuses à bras précitées. Ainsi le Demandeur a développé ces matériels roulants décrits notamment dans les brevets français publiés 2 882 913, 2 893 875, 2 896 715, 2 928 571, et non publié 0 858 038.For many years, the Applicant has been interested in providing independent equipment and equipment that facilitates the work of operators during the maintenance and renovation of building walls and ceilings and also in the finishing operations of those -this. Thus, the Applicant has designed and developed trolleys for the aforementioned applications. These trolleys include one or more hand sanders, a vacuum block and offer the autonomy of use for the operator. These trolleys are arranged to allow storage and maintenance in the vertical position of the sanders or arms but also their removal to then allow to perform the work for which they are intended. In the context of the proposed solutions, the Applicant has also provided to be able to orient in position with appropriate supports the positioning, articulation and orientation of the above-mentioned arm sanders. Thus the Applicant has developed these rolling stock described in particular in French patents published 2,882,913, 2,893,875, 2,896,715, 2,928,571 and not published 0 858 038.

Il est donc ainsi connu de proposer un matériel roulant formant desserte présentant une plate-forme inférieure munie de moyens de roulement et incluant dans sa partie arrière un cadre vertical formant guidon de préemption et de manoeuvre. Le bloc aspirateur est disposé sur une plate-forme du chariot-desserte tandis qu'un carter entourant permet le positionnement et la fixation temporaire et démontable d'une ou de plusieurs ponceuses à bras.It is therefore well known to propose a rolling stock forming a service having a lower platform provided with means of bearing and including in its rear part a vertical frame forming pre-emption handlebar and maneuvering. The vacuum unit is disposed on a platform of the carriage-serving while a surrounding housing allows the positioning and temporary and removable attachment of one or more hand sanders.

La démarche du Demandeur a été encore d'optimiser la conception de ce matériel roulant incluant une ou plusieurs ponceuses à bras pour faciliter la manipulation par l'opérateur. Plus particulièrement le Demandeur s'est attaché à améliorer l'intégration du bloc aspirateur, et aussi des moyens permettant la manipulation de ces matériels roulants. Par rapport à l'Art Antérieur rappelé dans les brevets précités du Demandeur, la démarche de ce dernier a aussi été de concevoir un matériel roulant beaucoup moins encombrant et stockable dans des lieux plus exigus de rangement.The Applicant's approach was to further optimize the design of this rolling stock including one or more hand sanders to facilitate handling by the operator. More particularly, the Applicant has endeavored to improve the integration of the vacuum block, and also the means for handling these rolling stock. Compared to the prior Art recalled in the aforementioned patents of the Applicant, the approach of the latter has also been to design a rolling stock much less bulky and storable in smaller places of storage.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

La structure roulante sous forme de chariot-desserte est référencée dans son ensemble par (M) et est susceptible de permettre le positionnement, le rangement, et le stockage à la verticale d'une ou de plusieurs ponceuses à bras (1) connues en soi et telles que décrites par exemple dans les brevets du Demandeur précités.The rolling structure in the form of trolley-service is referenced as a whole by (M) and is likely to allow the positioning, the storage, and the vertical storage of one or more portable sanders (1) known per se and as described, for example, in the aforementioned Applicant's patents.

L'originalité de l'invention réside dans le fait que le chariot-desserte est susceptible d'être utilisé et positionné selon les besoins de l'opérateur dans deux positions différentes sans aucune modification de la structure. Ces deux positions qui sont notamment illustrées aux figures 6 et 7 sont relatives respectivement à l'utilisation et au déplacement du chariot-desserte dans une configuration connue pour les aspirateurs dits aspirateurs-traineaux couramment utilisés pour les ménages domestiques, à la différence que le chariot-desserte selon l'invention est déplaçable dans les deux positions. L'autre position est celle plus classique où le chariot-desserte se présente en position verticale selon l'Art Antérieur rappelé précédemment en permettant l'utilisation du plateau supérieur pouvant servir d'établi et le rangement à la position verticale des ponceuses à bras en situation de stockage.The originality of the invention lies in the fact that the trolley-service is likely to be used and positioned according to the needs of the operator in two different positions without any modification of the structure. These two positions, which are illustrated in particular in Figures 6 and 7 relate respectively to the use and the displacement of the trolley in a known configuration for vacuum cleaners called vacuum cleaners-sleds commonly used for domestic households, with the difference that the trolley-serving according to the invention is movable in both positions . The other position is the more conventional one where the carriage-service is in a vertical position according to the prior art previously recalled by allowing the use of the upper plate which can to serve as a workbench and the storage in the vertical position of arm-held sanders.

Ainsi le chariot-desserte comprend un carter cylindrique (2) central recevant intérieurement le système d'aspiration et de chaque côté en extrémité du dit carter deux blocs (3) et (4) opposés qui sont aménagés chacun avec des moyens de roulement (5) et (6) et qui définissent avec le dit cylindre un ensemble de volume parallépipédique pouvant être mis en déplacement sur deux roues ou quatre roues selon les conditions d'utilisation. On définit ainsi un bloc inférieur (3) et un bloc supérieur (4) dont les fonctions vont être précisées.Thus the trolley-service comprises a central cylindrical casing (2) receiving internally the suction system and on each end side of said casing two opposing blocks (3) and (4) which are each arranged with rolling means (5). ) and (6) and which define with said cylinder a set of parallelepipedal volume that can be moved on two wheels or four wheels depending on the conditions of use. This defines a lower block (3) and an upper block (4) whose functions will be specified.

Le bloc inférieur(3) est susceptible d'être en regard du sol lorsque le chariot-desserte est en position verticale. Ce bloc (3) est aménagé intérieurement et extérieurement pour la réception de différents composants. Intérieurement, le bloc est ajusté avec des moyens et des conduits qui sont reliés à la source aspirante située à l'intérieur du carter cylindrique (2), et aussi le positionnement et le développement d'un flexible (14) de raccordement entre la ponceuse à bras et le système aspirant. Extérieurement, le bloc inférieur (3) est aménagé avec une configuration volumétrique carrée et présente sur sa face supérieure (3.1) des aménagements (3.2) formant logement pour autoriser le positionnement d'accessoires (1.1) de l'une ou des ponceuses à bras, et aussi permettre le positionnement des parties manuelles de préhension en extrémité des dites ponceuses à bras. Ce bloc inférieur (3) présente sur l'avant une ouverture ou découpe (3.3) permettant le passage du flexible (14) de raccordement entre la ponceuse à bras et le système aspirant. Le bloc inférieur (3) intègre dans sa partie arrière des logements pour le positionnement des roues (5) de manutention de manière que l'ensemble soit parfaitement intégré sans dépassement extérieur par rapport au volume du bloc. Dans sa partie arrière, le bloc inférieur (3) peut présenter des aménagements complémentaires pour la tenue d'éléments accessoires et composants (1.1) nécessaires aux ponceuses à bras du type tête de ponceuse, conduits de raccordement et d'exension En pratique, le bloc inférieur (3) présente dans sa partie centrale une découpe circulaire (3.6) correspondant à la section du carter cylindrique du système aspirant pour son centrage.The lower block (3) is likely to be facing the ground when the carriage is in vertical position. This block (3) is arranged internally and externally for receiving different components. Internally, the block is adjusted with means and conduits that are connected to the suction source located inside the cylindrical housing (2), and also the positioning and development of a hose (14) connection between the sander with arms and the suction system. Externally, the lower block (3) is arranged with a square volumetric configuration and has on its upper face (3.1) arrangements (3.2) forming a housing to allow the positioning of accessories (1.1) of one or the sander and also allow the positioning of the manual gripping portions at the end of said arm sanders. This lower block (3) has on the front an opening or cut (3.3) for the passage of the hose (14) connection between the sander arm and the suction system. The lower block (3) incorporates in its rear housing for the positioning of the wheels (5) handling so that the assembly is perfectly integrated without exceeding the outer volume of the block. In its rear part, the lower block (3) may have additional arrangements for the holding of accessory elements and components (1.1) required for sander-type sanding machines, connection and extension ducts In practice, the lower block (3) has in its central part a corresponding circular cutout (3.6) to the section of the cylindrical housing of the suction system for its centering.

En outre, le carter cylindrique (2) est aménagé pour la réception d'un conduit (9) d'aspiration. Figures 1 et 4, ce conduit se trouve à l'extérieur du carter en débouchant intérieurement. Figures 9-10, ce conduit est à l'intérieur du carter cylindrique.In addition, the cylindrical casing (2) is arranged for receiving a duct (9) suction. Figures 1 and 4 this duct is located outside the casing opening inside. Figures 9-10 this duct is inside the cylindrical housing.

Il est prévu alors dans le bloc inférieur (3) un conduit de raccordement (10) coudé en L avec une première extrémité (10-1) destinée à recevoir l'extrémité du flexible (14). L'autre extrémité (10-2) de ce conduit de raccordement déborde dans le conduit d'aspiration (9) disposé à l'intérieur du carter (1).It is then provided in the lower block (3) a connecting duct (10) angled L with a first end (10-1) for receiving the end of the hose (14). The other end (10-2) of this connecting pipe overflows into the suction duct (9) disposed inside the casing (1).

Le conduit d'aspiration (9) est équipé d'une attache (11) pour la réception d'un sac d'aspirateur (12) disposé dans le volume intérieur du carter en tout ou partie de celui-ci.The suction duct (9) is equipped with a fastener (11) for receiving a vacuum bag (12) disposed in the interior volume of the housing in whole or part thereof.

Le flexible (14) est ensuite enroulé en spirale à l'intérieur du bloc inférieur autour du conduit de raccordement (10) qui est ainsi profilé pour faciliter ce type de rangement.The hose (14) is then spirally wound inside the lower block around the connecting pipe (10) which is thus shaped to facilitate this type of storage.

Le bloc inférieur est agencé intérieurement avec des moyens permettant l'enroulement automatique du flexible et le verrouillage en position. A cet effet, le bloc inférieur est équipé d'un bouton de commande (13) d'enroulement du flexible.The lower block is arranged internally with means for the automatic winding of the hose and locking in position. For this purpose, the lower block is equipped with a control knob (13) for winding the hose.

Par ailleurs, une ou des sangles (non représentées) peuvent être utilisées pour maintenir le plus à l'horizontal les spires du flexible enroulé. Les sangles sont fixées de toute manière appropriée aux parois intérieures du bloc inférieur (3) et du conduit (10) de raccordement.In addition, one or more straps (not shown) can be used to keep the turns of the coiled hose as horizontal as possible. The straps are attached in any appropriate manner to the inner walls of the lower block (3) and the connecting duct (10).

Le bloc supérieur (4) présente un volume similaire à celui du bloc inférieur (3). Le bloc supérieur comprend aussi une découpe circulaire (4.1) susceptible de s'encastrer autour du cylindre (2), la fixation s'effectuant de toute manière appropriée dans une configuration démontable ou non. Ce bloc supérieur constitue sur sa face apparente une partie desserte (4.2) permettant le rangement d'outils ou autres accessoires. Dans son volume intérieur, le bloc supérieur reçoit l'équipement électrique permettant le fonctionnement du bloc aspirateur et aussi les prises de raccordement électrique pour le fonctionnement des ponceuses à bras. A cet effet, le bloc supérieur peut être aménagé sur l'un de ses côtés et de préférence avant pour constituer un tableau (4.3) pour les commandes électriques de raccordement, de voyants de sécurité, connecteurs de branchement et autres. Le bloc supérieur est aussi agencé avec des zones ou logements (4.4) pour le maintien et la fixation à la verticale de la ou les ponceuses à bras par leur partie la plus appropriée.The upper block (4) has a volume similar to that of the lower block (3). The upper block also comprises a circular cutout (4.1) capable of fitting around the cylinder (2), the fixing taking place in any suitable manner in a removable configuration or not. This upper block is on its visible side a serving part (4.2) for storing tools or other accessories. In its interior volume, the upper block receives the electrical equipment for the operation of the vacuum block and also the electrical connection sockets for the operation of the sander. For this purpose, the upper block can be arranged on one of its sides and preferably before to form a table (4.3) for electrical connection controls, safety lights, branch connectors and others. The upper block is also arranged with zones or housings (4.4) for holding and fixing the vertical or arm sanders by their most appropriate part.

Selon une autre disposition, le bloc supérieur (4) peut-être aménagé intérieurement en variante comme représenté figures 13-14 avec la réception d'un dispositif d'enroulement (15) du câble d'enroulement électrique permettant un enroulement de 4 à 5 mètres de câble sans frein.According to another arrangement, the upper block (4) can be fitted internally alternatively as shown Figures 13-14 with the receipt of a winding device (15) of the electric winding cable allowing a winding of 4 to 5 meters of cable without brake.

Selon une autre disposition de l'invention, les deux blocs (3) et (4) sont aménagés sur leurs faces arrières en regard pour autoriser le positionnement d'une poignée (7) escamotable, à la manière des poignées utilisées sur les valises, sacs et similaires, permettant leur traction grâce aux moyens de roulement incorporés. Ainsi comme représenté aux dessins, le bloc inférieur présente deux conduits fixes (8) à partir desquels la poignée (7) peut se développer comme représenté à la figure 5. Le chariot-desserte peut donc être facilement déplacé à l'aide de cette poignée qui est escamotée ensuite lors de l'utilisation du chariot-desserte ou lors de son stockage. Comme représenté figures 6 et 7, le chariot-desserte peut être translaté dans les deux positions représentées ce qui offre un gros avantage pour l'opérateur.According to another embodiment of the invention, the two blocks (3) and (4) are arranged on their rear faces opposite to allow the positioning of a retractable handle (7), in the manner of the handles used on the bags, bags and the like, allowing their traction thanks to the incorporated rolling means. Thus, as shown in the drawings, the lower block has two fixed ducts (8) from which the handle (7) can develop as shown in FIG. figure 5 . The trolley can be easily moved with the help of this handle which is then retracted when using the trolley or during storage. As shown Figures 6 and 7 , the cart-serving can be translated in the two positions represented which offers a big advantage for the operator.

Les avantages ressortent bien de l'invention et on souligne en particulier la réduction du volume d'encombrement du chariot-desserte, celui des accessoires dû au rangement du flexible d'aspiration et du rangement du câble électrique, son adaptabilité en deux positions d'utilisation et du roulement.The advantages are clear from the invention and in particular emphasizes the reduction of the volume of space of the trolley-service, that of the accessories due to the storage of the suction hose and the storage of the electric cable, its adaptability in two positions of use and bearing.
