Definitions
- the invention relates to the technical sector of tooling portable and more specifically tools for grinding or sanding intended for surfacing materials such as concrete and plaster.
- the diamond plates are shown for example in Figure 1 and are considered accessories to different surfacing devices such as giraffe sanders including a suction with synchronized vacuum cleaner at start or stop automatic, or concrete grinders.
- a tray diamond of the aforementioned type is shown in the drawings, Figure 1, and is referenced by (1). It is in the form of a disc, with a bottom wall (1a) support and positioning of a clamping means. Said bottom wall includes a circular central opening (1b) to allow passage to this effect of said clamping means, said wall then being extended by a partially spherical configuration intermediate wall (1c) provided openings (1d) for the flow of dust then by a crown peripheral (1e) parallel to the bottom wall. This crown receives a plurality of abrasive teeth (1f) arranged regularly on the periphery of the crown and internally to it in circles concentric.
- the aim sought after according to the invention was therefore to remedy the aforementioned drawbacks.
- the diamond plate abrasive is remarkable in that it is arranged in its bottom wall with a circular opening extended by a profiled cut communicating, creating a global non-circular shape, thus authorizing the intermediate insertion on the motor axis of a coupling disc complementary and drive arranged on the opposite face of the wall exterior of the tray with a complementary projecting shape capable of to engage and focus in the cutting and opening established on said wall of the diamond plate, in order to allow a coupling in order to the rotary drive of said diamond plate.
- the intermediate coupling disc eliminates the aforementioned slip effects and the abrasive plate turns at the same speed as the motor axis, and there is no more deterioration of the chainrings resulting from the forces linked to its mounting.
- the diamond plate is referenced by (1), arranged in the manner described above with the exception of its bottom wall (1a) which is arranged differently.
- Said wall (1a) thus has, as an extension of its opening circular (1b), a complementary cut out shape (1g) opening into the opening (1b) above and so as to create a global shape (F) not circular.
- This non-circular overall shape is likely to allow adjusting an intermediate disc (2) which has a central bearing threaded (2a) to allow connection and adjustment on the motor axis of the tool chuck.
- the intermediate disc thus has, on its face (2b) opposite the wall of the diamond plate, an overhanging circular surface (2c) of which the depth (p) corresponds to the thickness (c) of the bottom wall of the plate diamond. Said span is extended in the same plane and thickness by a complementary shape (2d) which is shaped so as to engage and mate directly in the corresponding cut shape (1g) of said wall, and the opening (1b).
- a protruding shape (2d) may have a complementary circular configuration, but any another form can be considered, the main thing being to ensure mating with the diamond plate.
- the intermediate disc has, on its other side in extension, another litter (2e) which is likely to come opposite and associate with the motor axis.
- the abrasive plate which is arranged in combination with the intermediate disc offers big advantages.
- the speed of rotation of the abrasive plate remains constant and there is no longer a speed difference.
- the interchangeability of diamond plate is made easy since the clamping elements come resting on the span of the intermediate disc. Assembly or disassembly of the whole is made easy.
- the intermediate disc absorbs the forces due to the work of the plate abrasive without any transmission then on the motor axis of the tool.

Claims (1)
- Plateau diamant abrasif du type en forme de disque avec une paroi de fond (la) d'appui et de positionnement d'un moyen de serrage, et comprenant une ouverture circulaire (1b), la paroi se prolongeant par une paroi (1c) intermédiaire puis par une couronne périphérique (le) parallèle à la paroi de fond et recevant une pluralité de dents (1f) abrasives,
caractérisé en ce qu'il est agencé dans sa paroi de fond avec une ouverture circulaire (1b) prolongée par une découpe profilée (1g) communiquante, créant une forme globale (f) non circulaire autorisant ainsi l'insertion intermédiaire sur l'axe moteur d'un disque d'accouplement (2) complémentaire et d'entraínement agencé sur la face (2b) en regard de la paroi extérieure du plateau avec une forme en saillie (2c - 2d) complémentaire comprenant une portée circulaire (2c) en débordement prolongée par une forme complémentaire (2d) et ayant une profondeur (p) correspondant à l'épaisseur (e) de la paroi de fond du plateau, et susceptible de s'engager et se centrer dans la découpe et l'ouverture établies sur ladite paroi du plateau diamant, afin de permettre un accouplement en vue de l'entraínement en rotation dudit plateau diamant.
