A holding device for hand machine tools, in particular a drill and/or a chipping hammer holding device, includes a hammer tube and at least one blocking body, which, when installed, connects the hammer tube to at least one additional holding component. The blocking body is provided with at least one blocking surface that is curved around at least one load tipping axis.

Holding device for hand machine tools, in particular holding device for a drill and/or chipping hammer

The invention is based on a hammer drill and/or chisel hammer, having an impact mechanism unit, an impact mechanism housing and at least one damping unit. The invention proposes that the damping unit is arranged on the impact mechanism housing along a main extension direction of the impact mechanism unit.

Hammer drill and/or chisel hammer

The invention relates to a hand power tool, in particular a drill hammer and/or chipping hammer, comprising a hammer unit () for producing a pulse in the direction of a hammer axis (). Said tool has an axial drive unit () with a drive element () and a motor unit (), in addition to a motor shaft (), which forms an angle () not equal to zero with the hammer axis () and which co-operates with the axial drive unit () by means of a torque transmission wheel () of said unit, the axial drive unit () being mounted on the opposite side of the torque transmission wheel () from the motor unit (). The driven element () of the axial drive unit () is mounted directly on the torque transmission wheel ().

Hand-held power tool, in particular a rotary hammer and/or chisel hammer

A hand-held power tool is proposed, having a drive device for driving a tool, which is arranged in a housing of the power tool. A handle of the power tool, which is movably connected to the housing of the power tool, is vibration-damped by a movable compensating element. For this purpose, the movable compensating element is operatively connected to the handle and/or the housing of the power tool by a deflecting system.

A device has a torque-limiting unit of a power drill, wherein torque-limiting unit is intended to limit a screwdriving moment in a screwdriving function; and a power drill is provided with the new torque-limiting unit.

Device having a torque-limiting unit

The invention relates to a striking mechanism of a handheld electric power tool, in particular a percussion drill and/or percussion hammer, having a hammer cylinder, a piston mounted with a guide section inside the hammer cylinder in a longitudinally displaceable manner, and a piston outer guide on which a guide area of the piston is guided in a longitudinally displaceable manner. A piston end located outside the hammer cylinder comprises an overlap for overlapping an end area of the hammer cylinder, and the guide area at least partially belongs to the overlap or is affixed there.

Striking mechanism for a handheld electric power tool

The invention relates to a hand tool machine (), in particular a drilling and/or percussion hammer, with a housing () and a vibration-damped handle () elastically supported relative to the housing () with two essentially parallel legs () and a coupling element (or) between each leg (or) and the housing () that is pin-jointed to the leg (or) and the housing (). The coupling elements () are connected to each other by a connector () that synchronizes the movements of the coupling elements ().

Hand-held power tool with a vibration-damped handle

The invention is based on an electric power tool having at least one drive unit and a gear unit, where the gear unit is a drive element for applying force to a piston unit. It is proposed that the drive element and the piston unit be arranged in an axially parallel manner. At least a region of the drive element overlaps axially with a longitudinal portion of the piston unit. The drive unit is arranged approximately centrally in an axial extension of the piston unit and the longitudinal axis of the drive unit is arranged transversely to the piston longitudinal axis.

Electric power tool

The invention is a striking mechanism for a handheld power tools in particular electric hammer. A piston is arranged in an axially bidirectionally movable manner in a guide tube. A striker is provided which acts on a striking pin and which is held in a movable manner in the guide tube. A compression space is delimited by the piston and the striker such that an air cushion is enclosed therein. It is proposed that at least one spring element is provided between the striker and the striking pin.

Striking mechanism for a handheld power tool

A hand-held power tool, has a housing, at least one partially hollow U-shaped C-shaped handle with a yoke part and two parallel leg parts and supported in a resilient manner such that the handle is movable relative to the housing in order to dampen vibrations, at least one coupling element accommodated at least partially inside the C-shaped handle to synchronize motion between the two leg parts and having a recess, and a switch arranged in a vicinity of the coupling element and having a switch housing extending in an interior of the handle and accommodated in the recess of the coupling element.

The invention relates to a hand machine tool (), particularly a percussion drill and/or percussion hammer, comprising a housing () having two parallel appendages (), a hollow, U-shaped, rounded handle () with a yoke () and two parallel legs (), said handle being movably supported on springs in relation to the housing () for the purpose of damping vibration. The appendages () of the housing () extend into both hollow legs () of the rounded handle (). The invention also comprises two coupling elements () situated in the hollow yoke () of the rounded handle () which serve to synchronize the movements of both legs (). The external end faces of the coupling elements () are flexibly connected to the appendages (). The coupling elements () are connected on the other end faces thereof to the rounded handle (), and cross each other, and are flexibly connected to each other at the crossing point.

Hand-held power tool with a vibration-damped rounded handle

The invention is based on a portable power tool having a vibration-damped handle () which has two legs () running in the longitudinal direction () of the portable power tool and which is motionally coupled to its housing (), wherein at least one lever () oriented transversely to the longitudinal direction () is coupled to each of the two legs () at an articulation point (), and wherein the levers () are coupled to a joint region () lying between the two legs () of the handle (). It is proposed that each lever () have a bearing point () between the joint region () and the respective articulation point ().

Handheld power tool with vibration-damped handle

The hand-held power tool has a vibration-damped main handle. The hand-held power tool has a device for fastening the main handle to a main element configured so that when the main element moves out of a stationary position toward the main handle the main element swivels around at least one swivel axis so that it is guided along a trajectory that extends with a slant of at least 10&#xb0; relative to a flat surface, which extends through a longitudinal tool axis and which has a surface normal oriented in a normal direction perpendicular to the longitudinal tool axis. As a result vibrations with a movement component perpendicular to the longitudinal tool axis are damped as well as vibrations that induce motion of the main element in the direction of the longitudinal tool axis toward the main handle.

Hand-held power tool with improved vibration-damped handle

The invention is based on a power hand tool, in particular a hammer drill and/or hammer chisel, with a percussion unit (), which comprises a tumble bearing unit () with a tumble body () and also a piston (). It is proposed that the power hand tool comprises at least two bearing locations () arranged in parallel in the force of flux, by means of which the tumble body () is coupled to the piston ().

Hand-held power tool with a percussion unit

The invention relates to an additional hand grip () for a hand machine tool, comprising a clamp () for clamping the additional hand grip () to a part of the hand machine tool, a handlebar () for gripping and holding of the additional hand grip (), and a pivot joint () that can be blocked, arranged between the clamp () and the handlebar (). The pivot joint () can be blocked with an eccentric tension lever (), which is formed by a pivotable part () of the handlebar ().
