A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, in particular having a first housing part, which is designed as a transmission housing, and a second housing part, which surrounds the drive unit, and a bearing unit, in particular a bearing housing, for supporting the drive unit. The bearing unit protrudes into the first housing part.

Hand-held power tool

A cooling device for a hand-held power tool, in particular an angle grinder, includes a first air guide channel configured to guide a first airflow and a first air inlet opening configured to guide the first airflow into a housing of the hand-held power tool. The first airflow is guided such that the first airflow extends/flows from the first air inlet opening to a side of the housing that faces away from the first air inlet opening.

Cooling device for a hand-held power tool

A handheld power tool includes an output shaft, a drive unit, a securing ring, and a securing element. The output shaft is configured to be releasably connected to an insert tool of the handheld power tool. The drive unit is configured to transmit a movement to the output shaft. The securing element is configured to secure the securing ring. The securing element has a recess which is provided to surround the securing ring in the radial direction in at least one operating state.

Handheld power tool

A portable power tool, in particular an angle grinder, includes a housing that accommodates a drive and an electronic device with an interface configured to electrically connect the electronic device. The power tool further includes a housing inner part that is configured as a drive housing and supports the electronic device. The interface has at least one first electrical interface contact region and at least one second interface contact region spaced apart from the first interface contact region. At least one insulating element spaced apart from the interface contact regions is arranged between the housing inner part and the electronic device. The insulating element is configured to avoid an electrical short-circuiting connection between the first interface contact region and the second interface contact region.

Portable power tool

A hand-held power tool includes a housing, a filter support, a plurality of securing element, and an actuating unit. The filter support has receiving openings, at least one first fixing element, and at least one second fixing element. The receiving openings are configured to receive filter elements configured to seal the hand-held power tool against a penetration of dust into the housing of the hand-held power tool. First and second fixing elements are fixable to corresponding securing elements arranged on the hand-held power tool, and are configured to releasably fix the filter support to the housing. The actuation unit is actuatable to release the filter support from the hand-held power tool.

Hand-held power tool comprising a filter support

A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, and a user interface unit. The machine housing surrounds the drive unit. The drive unit is configured to transmit a motion to an output unit. The user interface unit is configured to operate the hand-held power tool, and is either (i) positioned on an inner element of the hand-held power tool, in particular a flat outer surface of the inner element, or (ii) connected to the inner element, in particular the flat outer surface of the inner element.

A work shoe, in particular a safety shoe, includes at least one passive protection unit which is intended to passively protect a shoe wearer at least against mechanical and/or electrical loads, and includes at least one active protection unit which has at least one sensor unit which is intended to detect at least one characteristic variable at least in order to enable a protection function and/or a comfort function. The sensor unit is configured at least for detecting at least one person-related characteristic variable and/or at least one environmental characteristic variable.

Work shoe

A machine-tool operating device includes at least one operating unit and at least one electronics unit. The at least one operating unit has at least one operating element that is configured to be actuated by an operator and at least one further operating element that is configured to be actuated by an operator. The at least one electronics unit is configured at least for switching at least one energy supply of a drive unit in accordance with actuation of the operating element and of the further operating element. One or more of the operating element and the further operating element are configured as a touch-sensitive electronic operating element.

Machine-tool operating device

A filter support for a handheld power tool includes at least one filter support element, a first fastening element, and a second fastening element. The filter support element includes at least one receiving opening configured to receive a filter element. The filter elements of the filter support are preferably associated with air inlet openings of the handheld power tool and are configured to filter dust particles and/or material particles from a cooling air flow. The filter support can be fastened to a handheld power tool via the first and second fastening elements. The first and the second fastening elements of the filter support can be connected to each other. Advantageously, no fastening elements are provided on the handheld power tool.

Filter support for a handheld power tool

A hand-held power tool, in particular an angle grinder, includes a tool receiver, a tool housing, and a drive motor arranged in the tool housing. The drive motor is configured to be switched on and off via an electric On/Off switch for driving the tool receiver. The hand-held power tool also includes an actuating device configured to actuate the On/Off switch. The actuating device has a pivotably mounted actuating element and a pivotably mounted pawl that is configured to be coupled to the actuating element. The pawl is further configured, in a free-running state, to move pivotably relative to the actuating element and, in an actuation state, to exert upon the actuating element an actuating force that actuates the actuating device.

A fastening unit for a radio and/or a sensor module includes at least one of a radio and a sensor module that is configured to connect with an external application unit. The fastening unit is detachably connectable to the at least one of the radio and sensor module.

Fastening unit for a radio and/or sensor module

An electric power tool has a tool receptacle and a tool housing in which a drive motor for driving the tool receptacle is arranged. The drive motor is switchable on and off via an electric switch. An operating part for indirectly actuating the switch is arranged on the tool housing and extends approximately parallel to a longitudinal axis of the tool housing. The operating part is lever-like and is pivotably arranged on the tool housing. An actuating member of the switch is displaceable approximately parallel to the longitudinal axis by an actuating force that acts on the operating part approximately perpendicularly to the longitudinal axis. The drive motor is switched on by the actuating force acting on the operating part against a restoring force of the switch, and the drive motor is switched off automatically, via the restoring force, when the operating part is released by a user.

Electric power tool

A handheld power tool includes at least one housing unit, at least one tool receptacle, at least one operating unit that has at least one operating element, and at least one electrical and/or electronic indication unit. The indication unit has at least one at least partially circumferentially arranged indication element that is configured to indicate at least one handheld power tool characteristic variable. The indication element in one embodiment is arranged on the housing unit in a region between the operating element the tool receptacle The indication element in another embodiment is arranged at least substantially adjacent to the operating element.

A hand-held power tool includes an electric motor, a housing, and a housing cover. The housing includes an opening located in the vicinity of carbon brushes of the electric motor, such that the carbon brushes can be removed through the opening in the housing. The housing cover includes air inlets through which cooling air can flow into the interior of the housing. The opening in the housing is detachably closed by the housing cover.
