Abstract

L'invention concerne un appareil à brosses commandées par un moteur, comprenant un arbre d'entraînement (8) sur lequel peut s'emboîter un porte-brosses interchangeable en forme générale de cylindre creux, dans lequel l'arbre d'entraînement (8) présente un entraîneur (19) agissant essentiellement dans le sens périphérique, et coopérant avec une saillie d'entraînement dirigée radialement vers l'intérieur, sur le porte-brosses, l'entraîneur (19) est élargi vers la saillie d'entraînement en direction de l'arbre, en vue d'obtenir un effet de coin lors de la coopération avec ladite saillie, l'entraîneur (19) étant formé dans la direction de l'arbre opposée à une surface d'appui (29), en vue de coopérer avec une bague-support intérieure du porte-brosses. L'invention a pour but d'améliorer la manipulation de l'appareil à brosses du type précité, tout en maintenant sa sécurité de fonctionnement. Ce but est atteint grâce au fait que l'entraîneur n'est pas inseré, ou seulement partiellement intégré, dans la surface d'appui (29), mais forme toutefois, sensiblement à partir d'un plan de la surface d'appui (29), une surface-guide (23) qui, vue en direction de l'arbre, est en retrait sensiblement à partir de la surface d'appui (29).
