Abstract

Eine Abdeckvorrichtung eines Werkzeuggerätes, das zumindest ein scheibenförmiges Werkzeug (6) aufweist, weist ein erstes Haubenteil (12) zum bereichsweisen Umgreifen des scheibenförmigen Werkzeuges (6), ein zweites Haubenteil (22), das gegenüber dem ersten Haubenteil (12) an einem Drehpunkt (15) schwenkbar gelagert ist, und einen Arretiermechanismus (41) zum lösbaren Positionieren des zweiten Haubenteils (22) gegenüber dem ersten Haubenteil (12) auf. Der Arretiermechanismus (41) umfasst weist Rastmittel (46) an einem der Haubenteile (12) und mit dem Rastmittel (46) verrastbare Gegenrastmittel (23) an dem anderen Haubenteil (22) auf. Der Arretiermechanismus (41) weist weiter ein an einem Lagerpunkt (45) schwenkbar an einem der Haubenteile (12) gelagertes Betätigungselement (42) mit einem Betätigungsabschnitt (43) und mit einem in einem Winkel davon abragenden Arretierabschnitt (44) auf, wobei das Rastmittel (46) an einem freien Ende des Arretierabschnitts (44) vorgesehen ist.
