  • Patent number: 8256528
    Abstract: A damper for mounting between a power tool, having an axis of vibration, and a handle. The damper includes a damping arrangement for damping impacts and a spacer. The spacer is dimensioned so that, when the damper is mounted to the power tool, a ratio of a first distance between the axis of vibration and the handle to a second distance between the axis of vibration and the damping arrangement is at least 2:1. Further, a handle having such a damper for a power tool, as well as the corresponding power tool having such a handle, are described.

  • Patent number: 8172003
    Abstract: A portable device having an overload protection device for motor-operated tools has a drive motor, a drive shaft connected to the drive motor and driven in rotation by the drive motor, and an output shaft for driving a cutting tool, wherein the output shaft is arranged substantially perpendicularly to the drive shaft. A drive pinion is connected to the drive shaft. A drum is supported on the output shaft and driven in rotation by the drive pinion. A coupling is arranged between the drum and the output shaft and engages the drum. The coupling is connected to the output shaft. When the output shaft is blocked, the coupling effects an automatic decoupling between the drum and the output shaft in order to prevent overloading of the drive motor.

  • Patent number: 7946353
    Abstract: A power tool, such as a hammer drill and/or a chiseling hammer, includes a lubricated transmission arranged in a sealed transmission box. The transmission box is in fluid connection with the atmosphere via a venting channel. A sealing element is arranged in the venting channel. The sealing element cooperates with the venting channel to create a meandering pathway for air to pass through the venting channel so that leakage of lubricant between the sealing element and the venting channel is at least substantially prevented.

  • Patent number: 7591325
    Abstract: A portable hand-guided power tool has a housing and a handle having a first leg and a second leg, wherein the handle is secured by the first and second legs to the housing such that the handle is pivotably connected by the first leg to the housing and the second leg is connected to the housing such that a pivoting movement between the handle and the housing is possible. A pressure spring is disposed between the second leg and the housing. A first pressure member is disposed at the handle and a second pressure member is disposed at the housing. The pressure spring is held with pretension between the first and second pressure members. The first pressure member has at least one hook element and, without the handle being mounted on the housing, the first pressure member is positive-lockingly hooked to the housing by engaging a receptacle of the housing so as to form a hook connection.

  • Publication number: 20070289761
    Abstract: An auxiliary handle for a hand-held power tool has a handle part gripped by a hand of an operator and defining an axial direction. An attachment part with which the auxiliary handle is to be attached to a power tool is provided. An elastic damping element connects the handle part and the attachment part, wherein the handle part is secured to the attachment part by positive fit. A unitary holding section is connected to the handle part or the attachment part and a unitary securing section is connected to the attachment part or the handle part. The holding section surrounds with lateral play in all directions the securing section on all sides so that a damping space is generated between the securing section and the holding section. The damping element fills out the damping space at least partially.
