Abstract

The tool, comprising an active part (A) with a disc (5) and a hollow body (1) containing a power transmission system, includes a suction turbine (6) that is rotated by a vacuum source (B) connected to it by a flexible hose (F). As the turbine rotates it drives the disc through the gear transmission system and at the same time draws in outside air together with any debris produced by the disc.

Description

EQUIPEMENT TRANSPORTABLE DESTINE A MEULER, PONCER, SURFACER, INCORPORANTTRANSPORTABLE EQUIPMENT FOR GRINDING, SANDING, SURFACING, INCORPORATING

UN DISPOSITIF A FONCTIONNEMENT PAR DEPRESSION L'invention se rattache au secteur technique des appareils et instruments électroportatifs de ponçage, meulage et surfaçage.  The invention relates to the technical field of electrical and portable devices for sanding, grinding and surfacing.

Selon l'art antérieur, il est bien connu d'utiliser des appareils électroportatifs du type ponceuses, meuleuses et similaires pour surfacer des parois, cloisons, permettant leur fonctionnement. En pratique, les différentes ponceuses et similaires de ce type sur le marché restent peu faciles à manipuler sur des périodes de temps importantes, car le poids du bloc moteur reste conséquent. Aussi, la manipulation de la ponceuse dans tous les sens et orientations est à la longue fastidieuse et pénible. En outre, l'évacuation des poussières, détritus, requiert d'incorporer à la ponceuse et similaires des moyens complémentaires d'aspiration qui viennent se brancher sur la ponceuse avec des flexibles ou similaires associés à une source d'aspiration ou sont incorporés dans la machine. C'est le cas par exemple des ponceuses girafes ou des ponceuses rotatives orbitales. Les manipulations restent cependant peu pratiques. En outre, lorsqu'ils sont incorporés, cela alourdit de manière importante lesdites ponceuses et similaires.  According to the prior art, it is well known to use power tools such as sanders, grinders and the like to surface walls, partitions, allowing their operation. In practice, the various sanders and the like of this type on the market remain difficult to handle over long periods of time, because the weight of the engine block remains substantial. Also, handling the sander in all directions and orientations is in the long run tedious and painful. In addition, the evacuation of dust, detritus, requires to incorporate in the sander and the like additional suction means which are connected to the sander with hoses or the like associated with a source of suction or are incorporated in the machine. This is the case for example giraffe sanders or rotary orbital sanders. The manipulations remain however impractical. In addition, when incorporated, this significantly increases said sanders and the like.

La démarche du demandeur a donc été de rechercher une nouvelle conception de ponceuse qui soit de manipulation aisée par l'opérateur et de grande efficacité, ainsi que l'évacuation des poussières et des détritus.  The applicant's approach was therefore to seek a new design sander that is easy to handle by the operator and high efficiency, as well as the evacuation of dust and debris.

La solution apportée par le demandeur va à l'encontre de la conception actuelle de ces appareils électroportatifs en s'affranchissant du bloc moteur.  The solution provided by the applicant goes against the current design of these devices by dispensing with the engine block.

Ainsi et selon l'invention, l'équipement transportable destiné à meuler, poncer, surfacer et opérations similaires., est remarquable en ce qu'il comprend une partie active réceptrice de l'outil agencée avec un corps creux intérieurement recevant un dispositif de transmission de puissance, ledit dispositif recevant à une extrémité la partie outil destinée à poncer, meuler, surfacer, et étant accouplé à son autre extrémité à une turbine, ladite turbine étant aménagée pour autoriser une ventilation et passage d'air en provenance de l'extérieur et étant connectée par un flexible à une source aspirante en créant une dépression, la turbine devenant aspirante, l'appareil fonctionnant sans moyen moteur électrique intégré.  Thus and according to the invention, the transportable equipment intended for grinding, sanding, surfacing and similar operations is remarkable in that it comprises a receiving active part of the tool arranged with an internally hollow body receiving a transmission device. of power, said device receiving at one end the tool portion intended to sand, grind, face, and being coupled at its other end to a turbine, said turbine being arranged to allow ventilation and passage of air from outside and being connected by a hose to a suction source creating a depression, the turbine becoming suction, the apparatus operating without integrated electric motor 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.

Pour fixer l'objet de l'invention illustrée d'une manière non limitative aux figures des dessins où : - la figure 1 est une vue de l'équipement intégrant une partie active selon l'invention connecté à la source aspirante. - la figure 2 est une vue de la partie active avant branchement de la source aspirante. - la figure 3 est une vue en coupe partielle de la partie active selon l'invention. - la figure 4 est une vue de la turbine intégrée à l'appareil.  For fixing the object of the invention illustrated in a non-limiting manner to the drawing figures in which: - Figure 1 is a view of the equipment incorporating an active part according to the invention connected to the suction source. - Figure 2 is a view of the active part before connection of the suction source. - Figure 3 is a partial sectional view of the active part according to the invention. - Figure 4 is a view of the turbine built into the device.

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.

L'équipement mettant en oeuvre l'invention est référencé dans son ensemble par (E) et comprend une partie active (A) utile réceptrice de l'outil à poncer, meuler, à surfacer ou autres, destinée à être manipulée par l'opérateur contre une paroi (P) ou cloison ou similaire, afin d'exécuter des travaux de ponçage, meulage, surfaçage ou similaire, ladite partie active étant reliée par un flexible (F) à un bloc aspirant (B) intégré par exemple dans une desserte roulante telle qu'illustrée par exemple figure 3. Cette desserte roulante est, par exemple, celle du type décrite dans la demande de brevet FR 0502612 appartenant au demandeur. Cette desserte est ainsi agencée intérieurement, protégé par un carter de protection, avec un bloc aspirateur.  The equipment embodying the invention is referenced as a whole by (E) and comprises a useful active part (A) receiving the tool to be sanded, ground, grinded or other, intended to be handled by the operator. against a wall (P) or partition or the like, in order to carry out sanding, grinding, surfacing or similar work, said active part being connected by a hose (F) to a suction block (B) integrated for example in a service area rolling wheel as illustrated for example in Figure 3. This rolling service is, for example, that of the type described in the patent application FR 0502612 belonging to the applicant. This service is thus arranged internally, protected by a protective casing, with a vacuum block.

La partie active comprend ainsi un corps creux (1) intérieurement recevant un dispositif de transmission (2) par engrenages, à angle droit, par exemple, avec deux pignons (2a-2b) de dentures différentes pour assurer une démultiplication appropriée, et montés sur deux axes (2c-2d) perpendiculaires montés sur des moyens de roulement (3-4) appropriés.  The active part thus comprises a hollow body (1) internally receiving a transmission device (2) by gears, at right angles, for example, with two pinions (2a-2b) of different teeth to ensure appropriate gearing, and mounted on two perpendicular axes (2c-2d) mounted on appropriate rolling means (3-4).

L'un (2c) des axes reçoit à fixation l'outil de ponçage (5) ou meulage ou similaire de tout type connu. L'autre axe (2d) est agencé pour recevoir une turbine (6) montée solidarisée par tous moyens de liaison (7) appropriés. Cette turbine (6) présente des ouvertures (6a) radiales permettant le passage et l'entrée d'air et des conduits (6b) avec ailettes (6c) qui constituent les moyens de rotation de la turbine qui travaille par aspiration. En outre, le flexible (F) est monté sur une coiffe (8) présentant un embout épaulé (8a) de réception. Cet emmanchement est effectué serré ou à l'aide de moyens de bridage rapportés. Ainsi, selon l'invention, la mise en fonctionnement du bloc aspirant (B) après branchement électrique va provoquer une dépression d'air à travers la turbine (6) et sa mise en rotation. Par le moyen de transmission (2), l'outil de ponçage ou équivalent sera à son tour sollicité en rotation pour effectuer les opérations de ponçage ou équivalentes désirées. Le bloc aspirant est choisi pour permettre la rotation de l'outil à la vitesse qui convient pour effectuer les travaux. L'opérateur saisit la partie active par un emplacement de préhension formé en saillie sur le corps et peut effectuer toutes les manoeuvres qu'il convient pour effectuer les travaux sur les parois, cloisons et similaires. La manipulation est facile, la charge à soulever est légère, en l'absence du bloc moteur. La desserte réceptrice du bloc aspirant est montée sur des moyens de roulement de sorte qu'elle peut se déplacer aisément en fonction des besoins de l'opérateur.  The one (2c) of the axes receives fixing the sanding tool (5) or grinding or similar of any known type. The other axis (2d) is arranged to receive a turbine (6) mounted secured by any connecting means (7) suitable. This turbine (6) has radial openings (6a) for the passage and entry of air and ducts (6b) with fins (6c) which constitute the means of rotation of the turbine which works by suction. In addition, the hose (F) is mounted on a cap (8) having a receiving shoulder (8a). This fitting is performed tight or using clamping means reported. Thus, according to the invention, the operation of the suction unit (B) after electrical connection will cause a vacuum of air through the turbine (6) and its rotation. By the transmission means (2), the sanding tool or equivalent will in turn be rotated to perform the desired sanding or equivalent operations. The suction block is chosen to allow the rotation of the tool at the appropriate speed to perform the work. The operator grasps the active part by a gripping position formed protruding from the body and can perform all the maneuvers that are suitable for performing work on walls, partitions and the like. The handling is easy, the load to lift is light, in the absence of the engine block. The receiving unit of the suction unit is mounted on rolling means so that it can move easily depending on the needs of the operator.

Selon le concept de l'invention, l'équipement fonctionne par la dépression, créée en aval par le bloc aspirant en supprimant tout moyen moteur dans l'outil de ponçage, meulage et similaire.  According to the concept of the invention, the equipment operates by the depression, created downstream by the suction unit by removing any motor means in the sanding tool, grinding and the like.

Sans sortir du cadre de l'invention, la partie active de l'équipement peut être changée selon les besoins à la condition bien sûr que les parties actives de remplacement soient agencées de manière similaire. En outre, le corps de la partie active peut intégrer ou non un système d'aspiration des poussières et autres détritus.25  Without departing from the scope of the invention, the active part of the equipment can be changed as needed provided, of course, that the active replacement parts are arranged in a similar manner. In addition, the body of the active part may or may not include a suction system for dust and other detritus.
