Description

L'invention se rattache au secteur technique des structures roulantes du type chariot-desserte utilisées dans l'industrie et le bâtiment, aménagées pour permettre au moins des opérations d'aspiration des détritus, matières usées de travaux d'entretien, réparation, façonnage.The invention relates to the technical sector of rolling structures of the trolley-serving type used in industry and building, arranged to allow at least suction operations of detritus, waste materials maintenance work, repair, shaping.

Le concept du chariot-desserte est déjà bien connu en soi en étant aménagé pour recevoir des outils ou autres accessoires nécessaires à des travaux en atelier pour les applications les plus diverses.The concept of the trolley-serving is already well known in itself being arranged to receive tools or other accessories necessary for workshop work for the most diverse applications.

Dans le domaine de la construction et du bâtiment, on utilise aussi des chariots-dessertes aux mêmes fins, mais qui en plus, sont susceptibles de recevoir de l'outillage électroportatif et aussi du matériel plus lourd et encombrant, telles les ponceuses à bras.In the field of construction and building, we also use trolleys for the same purpose, but in addition, are likely to receive power tools and also heavier and cumbersome equipment, such as hand sanders.

Le Demandeur a ainsi depuis plusieurs années conçu du matériel et des équipements autonomes qui facilitent le travail des opérateurs lors des opérations d'entretien, de rénovation de murs, de plafonds, de construction et lors d'opération de finition.As a result, the Applicant has for many years designed autonomous equipment and equipment that facilitates the work of operators during maintenance, renovation of walls, ceilings, construction and during finishing operations.

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 .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 especially in published French patents 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 thus known to provide a rolling stock forming a serving having a lower platform provided with rolling means 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 ces structures roulantes à des fins d'utilisation variées, de rangement et de stockage, de réduction d'encombrement, et en laissant à l'opérateur la liberté d'utilisation à partir d'une structure roulante standard optimisée pour effectuer des tâches variées de simples aspirations, et de travaux à l'aide d'outils variés.The Applicant's approach has been to further optimize the design of these rolling structures for various purposes of use, storage and storage, reduction of space, and leaving the operator freedom of use from a standard rolling structure optimized to perform varied tasks of simple aspirations, and works using various tools.

Egalement, le Demandeur s'est attaché à améliorer l'intégration d'un système aspirant, et également faciliter en toute circonstance la manipulation de ces matériels roulants.Also, the Applicant has endeavored to improve the integration of an aspiring system, and also facilitate in any circumstance the handling of these rolling stock.

Selon une première caractéristique de l'invention, la structure roulante du type comprenant un chariot-desserte recevant un bloc aspirateur et un carter présentant en partie supérieure une desserte pour la réception d'accessoires est remarquable en ce que le chariot-desserte comprend un carter cylindrique central recevant intérieurement un système d'aspiration et de chaque côté en extrémité du dit carter deux blocs inférieur et supérieur opposés qui sont aménagés chacun avec des moyens de roulement et qui définissent avec le dit cylindre un ensemble de volume parallépipédique pouvant être mis en déplacement sur deux roues ou quatre roues dans une configuration verticale sur deux roues ou dans une configuration horizontale sur quatre roues, et en ce que les dits blocs inférieur et supérieur sont aménagés pour recevoir notamment une poignée de préhension et de traction, et en ce que le bloc inférieur est aménagé pour permettre la réception d'un flexible de raccordement au système d'aspiration et à un moyen destiné à fonctionner pour l'exécution de travaux, et en ce que le bloc supérieur est aménagé pour recevoir les moyens de commande électrique de fonctionnement.According to a first characteristic of the invention, the rolling structure of the type comprising a trolley receiving a vacuum unit and a casing having in the upper part a service for receiving accessories is remarkable in that the trolley-service comprises a housing central cylinder receiving internally a suction system and on each side at the end of said housing two opposite lower and upper blocks which are each arranged with rolling means and which define with said cylinder a set of parallelepiped volume can be moved on two wheels or four wheels in a vertical configuration on two wheels or in a horizontal configuration on four wheels, and in that said lower and upper blocks are arranged to receive in particular a grip handle and traction, and in that the lower block is arranged to allow the reception of a connection hose to the suction system and a means intended to function for the execution of work, and in that the upper block is arranged to receive the electric operating control means.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These and other characteristics will be apparent from the rest of the description.

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 (1)The rolling structure in the form of trolley-service is referenced as a whole by (1)

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 1 et 3 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.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 1 and 3 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 where the carriage-service is in a vertical position according to the prior art previously recalled by allowing the use of the upper plate that can serve as a workbench.

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 le cas échéant extérieurement pour la réception de différents composants. Intérieurement, le bloc est agencé 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 un moyen (M) d'exécution de travaux telle qu'une ponceuse à bras et le système aspirant. Extérieurement, le bloc inférieur (3) présente une configuration volumétrique carrée. Ce bloc inférieur (3) présente sur l'avant une ouverture ou découpe (3.3) permettant le passage du flexible (14) de raccordement entre le moyen (M) d'exécution de travaux pour l'aspiration 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. 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 optionally externally for receiving different components. Internally, the block is arranged 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 connecting hose (14) between a means (M) performing work such as a sander and the suction system. Externally, the lower block (3) has a square volumetric configuration. This lower block (3) has on the front an opening or cutout (3.3) for the passage of the hose (14) connection between the means (M) for performing work for the suction 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 practice, the lower block (3) has in its central part a circular cutout (3.6) corresponding to the section of the cylindrical housing of the suction system for its centering.

Le moyen (M) d'exécution de travaux est choisi par l'opérateur en fonction de son besoin. Ce peut être un outil de ponçage, une ponceuse à bras, une brosse d'aspiration ou autres en étant relié au flexible (14).The job execution means (M) is chosen by the operator according to his need. It can be a sanding tool, a sander, a suction brush or others being connected to the hose (14).

En outre, le carter cylindrique (2) est aménagé pour la réception d'un conduit (9) d'aspiration. Figure 3, ce conduit se trouve à l'extérieur du carter en débouchant intérieurement. Figures 4 et 5, ce conduit (9) est à l'intérieur du carter cylindrique.In addition, the cylindrical casing (2) is arranged for receiving a duct (9) suction. Figure 3 this duct is located outside the casing opening inside. Figures 4 and 5 this duct (9) is inside the cylindrical casing.

Il est prévu 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).There is provided in the lower block (3) an L-shaped connection duct (10) 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 ajusté 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 adjusted internally with means allowing 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) may be used to keep the turns of the coiled hose as horizontal as possible. The straps are attached in any appropriate manner to the interior walls of the lower block (3) and the conduit (10). connection.

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 du moyen (M) telle que ponceuse 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.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 means (M) such as arm 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.

Selon une autre disposition, le bloc supérieur (4) peut-être aménagé intérieurement en variante comme représenté figures 8-9 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 8-9 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 3. 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 3 . 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 trolley-service can be translated in the two represented positions 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, son adaptabilité en deux positions d'utilisation et du roulement. On souligne aussi la réduction du volume d'encombrement des accessoires dû au rangement du flexible d'aspiration et du rangement du câble électrique.The advantages are apparent from the invention and in particular emphasizes the reduction of the volume of space of the trolley-service, its adaptability in two positions of use and the bearing. It also emphasizes the reduction of the volume of space of the accessories due to the storage of the suction hose and the storage of the electric cable.
