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.

Figure imgaf001
A covering device of a tool device, which has at least one disk-shaped tool (6), has a first hood part (12) for grasping the disk-shaped tool (6) in regions, a second hood part (22) opposite the first hood part (12) at a pivot point (15) is pivotally mounted, and a locking mechanism (41) for releasably positioning the second hood part (22) relative to the first hood part (12). The locking mechanism (41) comprises locking means (46) on one of the hood parts (12) and latching means (23) latchable with the latching means (46) on the other hood part (22). The locking mechanism (41) further comprises a pivoting on a bearing point (45) on one of the hood parts (12) mounted actuating element (42) with an actuating portion (43) and with a projecting at an angle thereof locking portion (44), wherein the locking means (46) is provided at a free end of the locking portion (44).
