The handle for a handheld power tool includes a grip portion which can be gripped by a user, a fastening portion by which the handle can be fastened to the handheld power tool, and an oscillation decoupling device which is designed to decouple oscillations acting on the fastening portion from the grip portion, wherein the oscillation decoupling device has a spring element with a settable spring stiffness.

Handle and handheld power tool

A hand-held power tool includes a tool holder for holding a chiseling tool, a machine housing (), and a striking mechanism () including a striking body () moved on a longitudinal axis () for exerting strikes on the tool in an impacting direction. A damper () is used for stopping the striking body (). The damper () includes a ring made up of multiple elastic beads situated along a circumferential direction around the longitudinal axis ().

Hand-held power tool

An electric hand-held power tool (), in particular a hammer drill or chipping hammer, having a percussion mechanism assembly (), which vibrates along a vibration axis (A), and a handle assembly (), which is vibrationally decoupled via an anti-vibration unit (), wherein the anti-vibration unit () has a coil spring (), oriented along the vibration axis (A), having a plurality of turns, wherein the coil spring () is in the form of a cylindrically progressive compression spring () having two stiffness regions (S, S) with different levels of stiffness.

Vibration-damped hand-held power tool

A side handle for a hand-operated power tool includes a handle rod disposed along a handle axis and a fastening mechanism, where the side handle is releasably fastenable to the hand-operated power tool by the fastening mechanism. The fastening mechanism includes a tensioning band that engages around a fastening axis and a tensioning mechanism. The tensioning mechanism has a pull rod that is anchored to the tensioning band and is displaceable along the handle axis and a tensioning wheel that is rotatable about the handle axis and engages in an external thread of the pull rod. A damper connects the handle rod to the fastening mechanism and includes a leaf spring with a longitudinal side oriented in an inclined manner to the fastening axis where the leaf spring has a slot. A splint is fastened to the pull rod and engages in the slot.

Side handle

A motor-driven saber saw includes a guide device releasably connectable with the saw housing () in a region of the neck () and including a guide element () for guiding the saber saw () over a workpiece, a connection device () for connecting the guide element () to the housing () and having at least one connection part extending along an axis (A) and connectable with the neck (), with the guide element () being supported on the at least one connection part () for displacement along the axis (A), and with the guide device () further including at least one spring element () located between the at least one connection part () and the guide element ().

Motor-driven saber saw with guide device

A hollow profile () formed of a flat material () having a width (d) has at least one groove () provided on an outer side of at least one of the plurality of walls () of the profile () and having a bottom () spaced form the outer side by depth (t) and two opposite, substantially flat side walls () extending substantially perpendicular to the bottom (), with the groove depth (t) of the at least one groove () amounting to from 0.5 to 2 times of the material thickness (d) of the flat material ().
