Abstract

L'invention concerne un dispositif qui peut être relié à la poignée d'un dispositif de coupe à brosse à la place de son élément de coupe de manière à convertir le dispositif de coupe à brosse en une pelle portative, par exemple pour retirer une couche de neige. Ledit dispositif, qui peut être défini comme un « élément en saillie », comprend une paire de lames opposées l'une à l'autre et solidaires d'un arbre pouvant être relié, par l'intermédiaire d'un ensemble de pignons, à l'arbre logé dans la poignée du dispositif de coupe à brosse. À travers l'arbre logé dans la poignée et l'ensemble pignon, le moteur de dispositif de coupe à brosse, lorsqu'il est activé, fait tourner les lames du dispositif. Un carter enveloppe partiellement les lames de manière à permettre à ces dernières, lors d'un mouvement de rotation de celui-ci, de ramasser la neige sur le sol et de la projeter loin du dispositif. Au lieu d'une paire de lames, l'objet de dispositif de l'invention peut comprendre une pluralité de poils, de manière à faire office de brosse rotative. L'invention concerne également une pelle portative constituée d'un dispositif de coupe à brosse comprenant l'objet d'élément en saillie de l'invention à la place de l'élément de coupe de celle-ci.
