Abstract

Es ist eine Handwerkzeugmaschine (1) mit einer Aufnah­ meöffnung (2) für einen Zusatzhandgriff (3) vorgeschlagen. Der Zusatzhandgriff (3) ist in sich starr und ohne Vibrations­ dämpfungsglied zur Schonung des Bedienenden ausgeführt. In die Aufnahmeöffnung (2) ist ein Rohrstück (4) mit einem Innengewinde (5) mit einem dieses Rohrstück (4) umgeben­ den Dämpfungsglied (6) einvulkanisiert. Die Dämp­ fungswirkung dieses Dämpfungsgliedes (6) kann genau auf die Vibrationscharakteristik der Handwerkzeugmaschine abgestimmt sein. Jeder übliche Zusatzhandgriff ohne Dämp­ fung ist brauchbar. It is a handheld power tool (1) with a holder opening (2) proposed for an additional handle (3). The additional handle (3) is rigid in itself and without vibrations attenuator designed to protect the operator. In the receiving opening (2) is a pipe section (4) with a Surround the internal thread (5) with a pipe section (4) vulcanized the attenuator (6). The damper The effect of this attenuator (6) can be precise the vibration characteristics of the hand machine tool be coordinated. Any usual additional handle without damper fung is useful.
