A fastening device for a suction hose includes a main body having a first fastening interface configured to fasten the main body to a handheld power tool and/or to an additional handle, in particular in a manner detachable without the use of tools. The main body further includes a second fastening interface configured to fasten the suction hose to the main body, in particular in a manner detachable without the use of tools. The fastening device also includes a joint unit configured to movably connect the suction hose to the handheld power tool and/or to the additional handle.

Suction-extraction attachment

A hand-held power tool device comprises an impact tool unit configured to generate a pulse on an insertion tool, and a sensor unit configured to detect at least one of at least one operating parameter, and at least one ambient parameter. The sensor unit includes at least one sensor element configured to detect a spatial position of the impact tool unit.

Hand-held power tool device

The disclosure relates to a hand-held power tool comprising a percussion mechanism, especially a rotary hammer and/or percussion hammer. According to the disclosure, at least one sensor unit comprising at least sensor for at least one mechanical measurement variable is provided for detecting at least one percussion parameter.

Hand-held power tool

Percussion unit, especially for a rotary hammer and/or percussion hammer, comprising a control unit which is designed for controlling a pneumatic percussion mechanism. According to the disclosure, the control unit comprises at least one load estimation device.

Percussion unit

A drill hammer and/or a chipper hammer device includes a hammer mechanism having a drive unit and a transmission unit. The transmission unit transmits a drive torque from a motor to the hammer mechanism. The transmission unit includes at least one planetary drive. A drive element of the drive unit is disposed on a transmission element of the planetary drive.

Drill hammer and/or chipping hammer device

Percussion unit, especially for a rotary hammer and/or percussion hammer, comprising a control unit which is designed for open-loop and/or closed loop control of a pneumatic percussion mechanism, and at least one operating condition sensor unit. According to the disclosure, the control unit is designed to detect at least one percussion mechanism parameter depending on measurement values of the operating condition sensor unit.

A percussion unit for a rotary hammer and/or percussion hammer includes a control unit that is configured for open-loop and/or closed loop control of a pneumatic percussion mechanism. In at least one operating state in which the control unit changes from an idle mode to a percussion mode, the control unit is configured to adjust at least one operating parameter temporarily to a starting value.

The disclosure relates to an electric tool, particularly a hand-held power tool, comprising a control unit which has control software with control parameters, and is provided for the purpose of controlling a drive unit. According to the disclosure, said electric tool comprises an interface unit that is provided to fundamentally update and/or modify the control software and/or the control parameters.

Electric tool

A hand-held power tool is equipped with a dust extraction device which includes a dust box for holding dust. A closing flap is arranged in a tube section which lies in the flow path to the dust box, and this closing flap can be adjusted between the closed position and the open position. The closing flap is pivotably held in the region of the inner wall of the tube section and can be opened in the direction of the dust box. In the closed position, the closing flap bears against a stop which protrudes into the tube section, extends at an angle with respect to the direction of flow through the tube connection piece, and forms a stop line or stop area against which the closing flap correspondingly bears.

Handheld power tool having a dust extractor

A drill hammer for the three operation modes of drilling, chiseling, and hammer-drilling has a motor with a motor shaft; a gear with an intermediate shaft, a driving gear wheel, a toothed slaving shaft , a shifting hub, and a driven gear wheel; a percussion mechanism with a wobble disk and a wobble gear wheel; and a driven shaft with a driving gear wheel and a drill chuck. The gear is configured to be changed over easily without axial displacement of running gears that mesh with one another so that the drill hammer is more robust, shorter or more compact, and lighter in weight. The drill hammer is thus simply and economically constructed and whose efficiency is not impaired by the gear shifting mechanism.

Drill hammer with three modes of operation

A portable power tool has a housing, a rotating sleeve provided for rotatably driving a tool and a rotatably supported in the housing by at least one bearing, a driving gear-wheel installed on the rotating sleeve in a freely rotating manner and drivable by a motor, a safety clutch that couples the driving gear-wheel with the rotating sleeve in a rotation-proof manner, the safety clutch having two clutch members that are slippable, with one of the clutch members being assigned to the driving gear-wheel and the other clutch member being assigned to the rotating sleeve in both cases in a rotation-proof manner, and with a coupling sleeve providing a force against which the clutch members are slippable when a limit torque is exceeded, the bearing being seated on the rotating sleeve in an axially displaceable manner and loaded by the coupling sleeve of the safety clutch against an axial stop of the rotating sleeve.

Portable power tool, in particular a drilling hammer and/or impact hammer

A device for locking a power tool to a battery pack has at least one movable locking bar mountable on the power tool and upon locking engaging a detent recess of the battery pack, and at least one unlocking device for manually disengaging the locking bar from the detent recess, wherein the unlocking device is mountable on the battery pack.

Device for locking a power tool to a battery pack, and battery pack

A portable power drill or hammer drill having a housing () which consists in particular of half shells () and accommodates a manual gearbox (), wherein a shift element () that can be rotated by hand converts its rotary movement into a shift movement, can be produced cost-effectively and can be easily operated, without lubricant escaping from the housing (), by the shift element () consisting of a shell-like handle part () which can be joined together with a further, shell-like shift part () in a sealing manner from outside and inside relative to a housing shell ().

Portable power drill with gearbox

A device for locking an electric tool with a rechargeable battery pack has at least one locking bar mounted on one element selected from the group consisting of the electric tool and rechargeable battery pack in a manner that allows it to move against a spring force, whereby when the electric tool and rechargeable battery pack are joined, the locking bar is engaged in succession in a first and a second recess of the other element selected from the group consisting of the electric tool and rechargeable battery pack, and is retained tightly in the second recess by a force of a spring and, to release a lock, is manually disengaged from the second recess, wherein the locking bar is engaged in the first recess while being disengaged from the second recess.

Device for locking an electric tool with a rechargeable battery pack

The present invention is directed to a switching device with a rotatably mounted operating element () and an eccentric element () for translating a rotational displacement () of the operating element () into a translatory displacement () of a switching element (), in particular a selector shaft of a hand-held power tool. It is provided that a shape of the eccentric element () differs significantly from that of a rod.
