A construction of an anti-vibration handle for electric machine tools has been described in DE 10055395 A1. Their nature consists in two rubber gas-filled rubber rings which lie between the machine body and the handlebar in specially shaped channels for this purpose.
Ein Nachteil der bekannten Konstruktion besteht darin, dass wegen des nachlassenden Gasdrucks infolge des Alterns des Gummimaterials das elektrische Werkzeug unstabil und damit gefährlich während der Arbeit wird. Die Vibrationen können außerdem nicht gelöscht werden. A disadvantage of the known construction is that because of the decreasing gas pressure due to the aging of the rubber material, the electric tool becomes unstable and thus dangerous during work. The vibrations can not be deleted.

In Einvernehmen mit dem Gebrauchsmuster kommen zwischen jeder Hälfte des Handgriffs einerseits und der teilbaren Trägerplatte andererseits elastische Profilelemente zu liegen. Die Teilbare Trägergrundplatte hat fixierende Flächen. Die elastischen Profilelemente haben fixierende Profile, die in den fixierenden Flächen zu liegen kommen. Jede Handgriffshälfte besitzt zentrierende Säulen, die die Verbindungsschrauben aufnehmen. Die zentrierenden Säulen liegen in Zentrierbohrungen, welche auf den elastischen Profilelementen stehen. Jeder Bestandteil der teilbaren Trägergrundplatte ist mit dem entsprechenden elastischen Profilelement unlößbar verbunden. In agreement with the utility model come between each half of the handle on the one hand and the divisible support plate on the other hand to rest elastic profile elements. The divisible Carrier base plate has fixing surfaces. The elastic profile elements have fixing profiles that come to lie in the fixing surfaces. Each handle half has centering pillars which receive the connecting screws. The centering columns are in center holes, which are on the elastic profile elements. Each component of the divisible carrier base plate is nonloslosbar connected to the corresponding elastic profile element.
Ein Vorteil des Antivibrationshandgriffs für elektrische Werkzeugmaschinen besteht darin, dass er eine sehr gute Löschung der Vibrationen während der Arbeit gewährleistet. Er garantiert außerdem hohe Sicherheit und hohe Langlebigkeit des elektrischen Werkzeugs.  An advantage of the anti-vibration handle for electric machine tools is that it ensures a very good cancellation of the vibrations during work. It also guarantees high safety and long life of the electric tool.

Embodiment for the anti-vibration handle for
elektrische Handgeräte  electric handsets
Der Antivibrationshandgriff für elektrische Werkzeugmashinen besteht aus zwei symmetrisch gegeneinander angeordneten und aus an den Körper des Handgeräts 3 durch Befestigungsschrauben 4 befestigten Handgriffhälften 1 , in welchen Vorderteilen eine in zwei teilbare Trägergrundplatte liegt. Zwischen jeder Handgriffhälfte 1 und der teilbaren Trägergrundplatte 2 liegen elastische Profilelemente 5. Die teilbare Trägergrundplatte 2 hat Fixierungsflächen 6. Die elastischen Profilelemente 5 haben fixierende Vorsprünge 7, welche auf die Fixierungsflächen 6 zu liegen kommen. Jede Handgriffhälfte 1 hat Zentrierungssäulen 8, durch welche die Verbindungsschrauben 9 hindurchgehen. Die Zentrierungssäulen 8 kommen in Zentrierungsbohrungen 10 zu liegen, welche sich auf den elastischen Profilelementen 5 befinden. Jeder Teil der Teilbaren Trägergrundplatte 2 ist fest mit dem entsprechenden elastischen Profilelement 5 verbunden. The anti-vibration handle for electric Werkzeugmashinen consists of two symmetrically arranged against each other and attached to the body of the handset 3 by mounting screws 4 handle halves 1, in which front parts is a divisible into two carrier base plate. Between each handle half 1 and the divisible support base plate 2 are elastic profile elements 5. The divisible support base plate 2 has fixing surfaces 6. The elastic profile elements 5 have fixing projections 7, which come to rest on the fixing surfaces 6. Each handle half 1 has centering columns 8 through which the connecting screws 9 pass. The centering columns 8 come to lie in centering holes 10 which are located on the elastic profile elements 5. Each part of the divisible support base plate 2 is fixedly connected to the corresponding elastic profile element 5.
Benutzung des Gebrauchsmusters Use of the utility model
Mit dem Antivibrationshandgriff für elektrische Werkzeugmaschinen arbeitet man folgendermaßen. Der Antivibrationshandgriff wird im Prinzip fabrikmäßig vormontiert und braucht keine weitere Nachstellungen. Da die zwei Handgriffhälften 1 in zusammengebautem Zustand isoliert vom Körper des Gerätes 3 sind, wird auf den Handgriff ein Minimum an Schwingungen übertragen. Die elastischen Profilelemente 5 sind völlig eingeschlossen, was ihre Zuverlässigkeit und Widerstandsfähigkeit auf eine sehr lange Zeitspanne garantiert. The anti-vibration handle for electric machine tools works as follows. The anti-vibration handle is in principle factory pre-assembled and needs no further adjustments. Since the two handle halves 1 in the assembled state are isolated from the body of the device 3, a minimum of vibrations is transmitted to the handle. The elastic profile elements 5 are completely enclosed, which guarantees their reliability and resistance over a very long period of time.
