Patent ID: 7614460

Claim:
A portable impact power tool comprising: a housing having at least one handle for manual support of the tool, an impact mechanism movably supported in the housing and having a forward end with an opening for receiving a working implement and a rear end located inside the housing, wherein the impact mechanism is arranged to deliver hammer blows to the working implement, a pivot joint arranged to support the impact mechanism relative to the housing at a point located between the forward end and the rear end of the impact mechanism, said pivot joint allowing longitudinal and pivotal movements but preventing in the support point radial and rotational movements of the impact mechanism relative to the housing, whereby the impact mechanism is supported in the housing such that both longitudinal and pivotal movements of the impact mechanism are absorbed and prevented from being transferred to the housing, and at least one resilient element mounted between the housing and the impact mechanism at a distance from said pivot joint for biasing the impact mechanism towards a neutral position relative to the housing while absorbing vibration movements of the impact mechanism.
