In den Figuren 6 und 7 ist das formschlüssige Ineinandergreifen des ersten Bauteils 34 und des zweiten Bauteils 36 des Zusatzhandgriffs 32 dargestellt. Hierzu ist ein vom Griffmittel 64 des ersten Bauteils 34 umfasster Teilbereich innen mit einem Hohlraum 82 versehen, der zur Aufnahme des zweiten Bauteils 36 vorgesehen ist (Figuren 4 und 6). Das zweite Bauteil 36 ist im Teilbereich 74 in einem dem Teilbereich 74 zugewandten Bereich des Aufnahmemittels 76 geschlitzt ausgeführt (Figur 3), so dass ein formschlüssiges Eingreifen in das erste Bauteil 34 möglich wird. Ein geschlitzter Bereich 84 (Figur 3) des zweiten Bauteils 36 ist dabei senkrecht zur Befestigungsachse ausgerichtet. Bei einer Montage des Zusatzhandgriffs 32 an den Spindelhals 44 der Bohr- und/oder Schlagbohrmaschine wird das zweite Bauteil 36 senkrecht zur Befestigungsachse mit dem Teilbereich 74 voran in den halbkreisförmigen Aufnahmebereich 70 und anschließend in den in Figur 6 gestrichelt dargestellten Hohlraum 82 des ersten Bauteils 34 eingeführt. Dabei wird das zweite Bauteil 36 so weit in das erste Bauteil 34 eingeführt, dass im Wesentlichen ein vollständiger Kreisdurchmesser K' des zweiten Bauteils 36 erhalten bleibt (Figur 6). Der Kreisdurchmesser K' des Aufnahmebereichs 78 ist auf einen Querschnitt des Spindelhalses 44 abgestimmt, so dass der Zusatzhandgriff 32 an den Spindelhals 44 nahezu spielfrei führbar ist. Um das zweite Bauteil 36 beim Einführen des Zusatzhandgriffs 32 in Position gegenüber dem ersten Bauteil 34 zu halten, werden das erste Bauteil 34 und das zweite Bauteil 36 miteinander über eine nicht näher dargestellte Schraubverbindung verschraubt. Der Zusatzhandgriff 32 mit dem ersten Bauteil 34 und dem zweiten Bauteil 36 wird mit der die Aussparungen 48 aufweisenden Seite voran über die Werkzeugaufnahme 52 auf den Spindelhals 44 geführt, bis die Aussparung 48 und die stegförmigen Erhebungen 46 formschlüssig ineinander greifen.

Der Zusatzhandgriff 32 kann dabei mittels der vier stegförmigen Erhebungen 46 am Spindelhals 44 und der Aussparungen 48 am Zusatzhandgriff 32 in unterschiedlichen radialen Ausrichtungen angebracht werden. Anschließend werden das erste Bauteil 34 und das zweite Bauteil 36 über die Schraubverbindung verklemmt, so dass das rippenförmige Befestigungselement 50 in die dafür vorgesehene nutförmige Aussparung 42 des Spindelhalses 44 formschlüssig eingreift und sich das erste Bauteil 34 und das zweite Bauteil 36 formschlüssig verbinden (Figur 7). Zum Lösen des Zusatzhandgriffs 32 wird die Schraubverbindung so weit gelockert, bis das rippenförmige Befestigungselement 50 von der nutförmigen Aussparung 42 freiliegt, so dass der Zusatzhandgriff 32 zunächst axial verschoben und anschließend bei Bedarf zusätzlich in Umfangsrichtung 20 verschoben werden kann.In the FIGS. 6 and 7 the positive engagement of the first component 34 and the second component 36 of the auxiliary handle 32 is shown. For this purpose, a partial region encompassed by the gripping means 64 of the first component 34 is internally provided with a cavity 82 which is provided for receiving the second component 36 ( FIGS. 4 and 6 ). The second component 36 is slotted in the subregion 74 in a region of the receiving means 76 facing the subregion 74 ( FIG. 3 ), allowing a positive intervention in the first Component 34 is possible. A slotted region 84 (FIG. 3) of the second component 36 is aligned perpendicular to the fastening axis. When mounting the auxiliary handle 32 to the spindle neck 44 of the drilling and / or percussion drill, the second component 36 is perpendicular to the mounting axis with the portion 74 ahead in the semicircular receiving area 70 and then in the FIG. 6 Dashed cavity 82 of the first component 34 introduced. In this case, the second component 36 is inserted so far into the first component 34 that substantially a complete circle diameter K 'of the second component 36 is maintained ( FIG. 6 ). The circle diameter K 'of the receiving area 78 is matched to a cross section of the spindle neck 44, so that the auxiliary handle 32 can be guided on the spindle neck 44 almost free of play. In order to hold the second component 36 in the insertion of the auxiliary handle 32 in position relative to the first component 34, the first component 34 and the second component 36 are screwed together via a screw, not shown. The additional handle 32 with the first component 34 and the second component 36 is guided with the recesses 48 having the side of the tool holder 52 on the spindle neck 44 until the recess 48 and the web-shaped projections 46 engage positively in one another. For this purpose, the second component 36 is shorter than the first component 34 by an extension length of the recesses 48 in the axial direction 28 (FIG. 3). The auxiliary handle 32 can be attached by means of four web-shaped elevations 46 on the spindle neck 44 and the recesses 48 on the auxiliary handle 32 in different radial orientations. Subsequently, the first component 34 and the second component 36 via the screw clamped so that the rib-shaped fastening element 50 positively engages in the groove-shaped recess 42 provided for this purpose of the spindle neck 44 and the first component 34 and the second component 36 connect in a form-fitting manner ( FIG. 7 ).

In den Figuren 8 und 9 ist eine alternative Ausgestaltung des Zusatzhandgriffs 32 dargestellt. Bezüglich gleich bleibender Merkmale und Funktionen kann auf die Beschreibung zum Ausführungsbeispiel in den Figuren 1 bis 7 verwiesen werden. Sich im Wesentlichen entsprechende Bauteile und Merkmale sind grundsätzlich mit den gleichen Bezugszeichen beziffert. Die in den Figuren 8 und 9 nachfolgende Beschreibung beschränkt sich im Wesentlichen auf die Unterschiede zum Ausführungsbeispiel in den Figuren 1 bis 7.In the FIGS. 8 and 9 an alternative embodiment of the auxiliary handle 32 is shown. With regard to features and functions that remain the same, reference may be made to the description of the exemplary embodiment in FIGS FIGS. 1 to 7 to get expelled. Basically corresponding components and features are numbered in principle with the same reference numerals. The in the FIGS. 8 and 9 The following description is essentially limited to the differences from the exemplary embodiment in FIGS FIGS. 1 to 7 ,

Das zweite Bauteil 36 weist das Befestigungsmittel 18 zur Erzielung einer Formschlussverbindung in Umfangsrichtung 20 auf. Die Aussparungen 48 erstrecken sich entlang eines Teilabschnitts 56 des Aufnahmemittels 76 des zweiten Bauteils 36 in Umfangsrichtung 20, wobei der Teilabschnitt 56 mit den Aussparungen 48 im montierten Zustand in die Aussparungen 48 des ersten Bauteils 34 übergeht. Zudem ist das rippenförmige Befestigungselement 50 des ersten Bauteils 34 von einem gestanzten Blechteil gebildet.The second component 36 has the fastening means 18 for achieving a positive connection in the circumferential direction 20. The recesses 48 extend along a portion 56 of the receiving means 76 of the second component 36 in the circumferential direction 20, the portion 56 merges with the recesses 48 in the mounted state in the recesses 48 of the first member 34. In addition, the rib-shaped fastening element 50 of the first component 34 is formed by a stamped sheet metal part.

Zum Verklemmen des ersten Bauteils 34 mit dem zweiten Bauteil 36 umfasst der Zusatzhandgriff 32 in den Figuren 8 und 9 ein drittes Bauteil 86. Das dritte Bauteil 86 umfasst hierzu ein Griffmittel 88, das drehbar im ersten Bauteil 34 eingeführt wird und über eine in Figur 9 dargestellte Gewindestange 90 mit dem zweiten Bauteil 36 verschraubt wird. Der Teilbereich 74 des zweiten Bauteils 36 umfasst hierzu eine Ausnehmung 92 mit einer in die Ausnehmung 92 eingelegten Mutter 94. Die Mutter 94 weist eine Verdrehsicherung auf und ist formschlüssig in eine Kunststoffwandung des Teilbereichs 74 des zweiten Bauteils 36 eingebunden. Zudem befindet sich im Hohlraum 82 des ersten Bauteils 34 eine Feder 96, die um die Gewindestange 90 des dritten Bauteils 86 angeordnet ist und die im montierten Zustand des Zusatzhandgriffs 32 vorgespannt ist. Wird durch Drehung des dritten Bauteils 86 die Schraubverbindung zum zweiten Bauteil 36 gelöst, bewirkt eine Federkraft der Feder 96, dass das zweite Bauteil 36 aus dem ersten Bauteil 34 herausgedrückt wird und sich das rippenförmige Befestigungselement 50 von der nutförmigen Aussparung 42 des Spindelhalses 44 löst, und der Zusatzhandgriff 32 kann vom Spindelhals 44 der Handwerkzeugmaschine 12 abgenommen werden.For clamping the first component 34 with the second component 36, the auxiliary handle 32 comprises in the FIGS. 8 and 9 a third component 86. For this purpose, the third component 86 comprises a gripping means 88, which is rotatably inserted in the first component 34 and via an in FIG. 9 shown threaded rod 90 is screwed to the second component 36. For this purpose, the partial region 74 of the second component 36 comprises a recess 92 with a nut 94 inserted into the recess 92. The nut 94 has an anti-rotation lock and is positively integrated in a plastic wall of the partial region 74 of the second component 36. In addition, located in the cavity 82 of the first member 34, a spring 96 which is disposed about the threaded rod 90 of the third member 86 and which is biased in the assembled state of the auxiliary handle 32. If the screw connection to the second component 36 is released by rotation of the third component 86, a spring force of the spring 96 causes the second component 36 to be pushed out of the first component 34 and the rib-shaped fastening element 50 to come away from the groove-shaped recess 42 of the spindle neck 44, and the auxiliary handle 32 can be removed from the spindle neck 44 of the power tool 12.

Grundsätzlich ist es auch denkbar, dass das rippenförmige Befestigungselement 50 federbelastet ist, so dass bei einem Einführen des Zusatzhandgriffs 32 das rippenförmige Befestigungselement 50 in die nutförmige Aussparung 42 des Spindelhalses 44 einrastet, sobald der Zusatzhandgriff 32 formschlüssig mit dem Spindelhals 44 in Umfangsrichtung 20 verbunden ist.In principle, it is also conceivable that the rib-shaped fastening element 50 is spring-loaded, so that upon insertion of the auxiliary handle 32, the rib-shaped fastening element 50 engages in the groove-shaped recess 42 of the spindle neck 44, as soon as the auxiliary handle 32 is positively connected to the spindle neck 44 in the circumferential direction 20 ,
