Title
(DE) HANDWERKZEUGMASCHINE
(EN) HAND-HELD POWER TOOL
(FR) OUTIL ELECTRIQUE A MAIN
Abstract
(DE)
Eine Handwerkzeugmaschine, insbesondere Winkelschleifmaschine, weist ein Maschinengehäuse (10) auf, das in ein Motorgehäuse (11) und einen an dessen einer Stirnseite angeordneten Handgriff (15) unterteilt ist, wobei der Handgriff (15) relativ zum Motorgehäuse (11) um dessen Längsachse drehbar ausgebildet ist. Eine Fixiervorrichtung (20) sorgt für eine Festlegung des Handgriffs (15) in mindestens zwei vorgegebenen Drehstellungen am Motorgehäuse (11). Zwecks einer einfachen konstruktiven Ausführung der Fixiervorrichtung (20) bei guter Drehführung des Handgriffs (15) am Motorgehäuse (11) ist am letzteren ein Lagerstutzen (22) angeformt, auf dem ein Drehkreuz (24) axial unverschieblich und drehbar aufgenommen ist. Das Drehkreuz (24) ist mit dem Handgriff (15) fest verbunden, und die Fixiervorrichtung (20) bewirkt eine formschlüssige Verriegelung zwischen Motorgehäuse (11) und Drehkreuz (24).
(EN)
Described is a hand-held power tool, in particular an angle grinder, with a casing (10) divided into a motor housing (11) and a handle (15) located at one end of the motor housing. The handle (15) is designed so that it can rotate relative to the motor housing (11) about the longitudinal axis of the motor housing (11). A fixing (20) enables the handle to be fixed in two predetermined rotational positions on the motor housing (11). In order to provide a simple fixation design ensuring optimum handle-rotation characteristics, the motor housing has a support stud (22) moulded on it, the support stud holding a spider (24) so that it can rotate but cannot move longitudinally. The spider (24) is rigidly joined to the handle (15), and the fixing (20) rigidly locks the motor housing (11) to the spider (24).
(FR)
Un outil à main, en particulier une meuleuse d'angle, présente un carter (10) subdivisé en un carter de moteur (11) et une poignée (15) disposée sur une surface frontale de ce carter de moteur. La poignée (15) tourne par rapport au carter de moteur (11) autour de l'axe longitudinal de celui-ci. Un dispositif de blocage (20) assure une fixation de la poignée (15) dans au moins deux positions de rotation déterminées sur le carter de moteur (11). Pour simplifier la conception du dispositif de blocage (20) tout en permettant un pivotement correct de la poignée (15) sur le carter de moteur (11), un support (22) est moulé sur ledit carter de moteur et reçoit un croisillon (24) tournant, qui est fixe dans le sens axial. Le croisillon (24) est solidaire de la poignée (15), et le dispositif de blocage (20) provoque un verrouillage par liaison de forme entre le carter de moteur (11) et le croisillon (24).
