Description
Die Erfindung geht aus von einer Handwerkzeugmaschine nach der Gattung des Hauptanspruchs. Es ist schon eine solche Handwerkzeugmaschine mit einem solchen, ihr zugeordneten Zusatzhandgriff bekannt geworden durch die DE-PS 28 04 223. Der dort beschriebene konstruktive Aufwand ist jedoch ver hältnismäßig groß und erfordert speziell für diesen Zweck gefertigte Dämpfungselemente. Zudem besteht der Nachteil, daß der Zusatzhandgriff für jede Handwerkzeugmaschine speziell abgestimmte Dämpfungselemente besitzen muß wenn die Dämpfung optimal sein soll.The invention is based on a hand machine tool the genus of the main claim. It is already one Hand machine tool with one assigned to it Additional handle made known by DE-PS 28 04 223. However, the design effort described there is ver relatively large and requires specifically for this purpose manufactured damping elements. There is also the disadvantage that the additional handle for every hand machine tool must have specially matched damping elements if the damping should be optimal.
Die erfindungsgemäße Handwerkzeugmaschine mit den kenn zeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß das Dämpfungsglied mittels marktgängiger Einzelteile aufgebaut, in sie eingebracht und ganz speziell auf diese Handwerkzeugmaschine abgestimmt werden kann. The hand tool according to the invention with the kenn drawing features of the main claim has in contrast the advantage that the attenuator by means of marketable Individual parts assembled, inserted into them and very special can be matched to this hand tool.
Besonders vorteilhaft kann dabei die Nutzung der Dämpfungs eigenschaften des Dämpfungsgliedes gestaltet werden, indem das Dämpfungsglied symmetrisch zur Mittelsenkrechten des Gehäusequerschnitts die Gehäuselängsachse kreuzend in das Handwerkzeugmaschinengehäuse eingebracht ist.The use of damping can be particularly advantageous characteristics of the attenuator can be designed by the attenuator symmetrical to the perpendicular to the Cross section of the housing longitudinal axis in the Hand machine tool housing is introduced.
Zwei Ausführungsbeispiele des Erfindungsgegenstandes sind in der Zeichnung dargestellt und in der nachfolgenden Be schreibung näher erläutert. Es zeigen Fig. 1 eine erste Ausführungsform des Erfindungsgegenstandes mit einer An sicht des Gehäuses und des Zusatzhandgriffs teilweise ge schnitten und Fig. 2 eine zweite Ausführungsform des Er findungsgegenstandes mit einer Ansicht des Gehäuses und des Zusatzhandgriffs, teilweise geschnitten.Two embodiments of the subject matter of the invention are shown in the drawing and described in more detail in the following description. In the drawings Fig. 1 shows a first embodiment of the subject invention with a to view of the housing and of the auxiliary handle partially ge cut and Fig. 2 shows a second embodiment of he invention article partially cut with a view of the housing and the auxiliary handle.
Im ersten Ausführungsbeispiel ist in ein Gehäuse 1 einer Handwerkzeugmaschine eine Aufnahmeöffnung 2 für einen Zusatzhandgriff eingebracht. In diese Aufnahmeöffnung 2 ist ein Rohstück 4 mit einem Innengewinde 5 eingesetzt. Dabei ist dieses Rohstück 4 mittels eines gummielastischen Mantels 6 in die Aufnahmeöffnung 2 des Gehäuses einvulkani siert. Die Elastizität des Mantels 6 kann entsprechend der Vibrationscharakteristik der Handwerkzeugmaschine gewählt werden, um einen optimalen Dämpfungseffekt zu erzielen. Als Zusatzhandgriff 3 kann jeder bisher bekannte Hand griff ohne Dämpfungsmittel verwendet werden. In the first exemplary embodiment, a receiving opening 2 for an additional handle is introduced into a housing 1 of a handheld power tool. A raw piece 4 with an internal thread 5 is inserted into this receiving opening 2 . In this case, this blank piece 4 is Siert by means of a rubber-elastic jacket 6 in the receiving opening 2 of the housing einvulkani. The elasticity of the jacket 6 can be selected according to the vibration characteristics of the hand machine tool in order to achieve an optimal damping effect. As an additional handle 3 , any previously known hand grip can be used without damping means.
In einem zweiten Ausführungsbeispiel nach Fig. 2 ist in einem Gehäuse 7 eine Aufnahmeöffnung 8 für eine Befestigungs vorrichtung für einen Zusatzhandgriff 9 angeordnet. In die Aufnahmeöffnung 8 ist ein Bolzen 10 mit einem Innengewinde 11 und einem Schaft 12 mittels eines gummielastischen Man tels 13 einvulkanisiert. Dabei sind der Schaft 12 und der Mantel 13 einer Mittelsenkrechten 14 des Gehäusequerschnitts symmetrisch zugeordnet und so gelegt, daß sie die durch einen Punkt 15 angedeutete Gehäuselängsachse rechtwinklig kreuzen. Der Außendurchmesser des Bolzens 10 ist dabei so gehalten, daß er reichlich Spiel in der Aufnahmeöffnung 8 hat. Zum Vibrationsausgleich zwischen dem Gehäuse 7 und dem Zusatzhandgriff 9 ist also genügend Freiraum vorhanden. Der Gewindezapfen des Zusatzhandgriffs 9 ist selbstverständ lich eingeschraubt in das Innengewinde 11 des Bolzens 10.In a second embodiment according to FIG. 2, a receiving opening 8 for a fastening device for an additional handle 9 is arranged in a housing 7 . In the receiving opening 8 , a bolt 10 is vulcanized with an internal thread 11 and a shaft 12 by means of a rubber-elastic man 13 . The shaft 12 and the jacket 13 are symmetrically associated with a perpendicular 14 of the housing cross section and placed so that they cross the housing longitudinal axis indicated by a point 15 at right angles. The outer diameter of the bolt 10 is held so that it has plenty of play in the receiving opening 8 . Sufficient space is therefore available for vibration compensation between the housing 7 and the additional handle 9 . The threaded pin of the additional handle 9 is of course screwed into the internal thread 11 of the bolt 10 .
