A handheld power tool includes a housing having a handle, a drive motor situated in the housing, and a first interface, the interface being designed to receive pieces of information from at least one second external interface and/or to transmit them to at least one second external interface. The housing has a receptacle opening, the first interface being situated so it is removable in the receptacle opening. Furthermore, the receptacle opening is detachably closable by a cover, the cover locking up the housing toward the outside.

Handheld power tool

In a hand-held power tool, a torque clutch associated with an output spindle, a transmission element axially displaceable in the direction of a longitudinal center axis of the output spindle, a locking element axially immovable in the direction of the longitudinal center axis and movable in a plane transverse to the longitudinal center axis, for activating and deactivating the torque clutch, the locking element enabling, in at least a first operating position, axial displaceability of the transmission element in the direction of the longitudinal center axis to activate the torque clutch, and in at least a second operating position, for at least limiting the axial displaceability of the transmission element to deactivate the torque clutch, in the second operating position of the locking element, the output spindle being at least essentially axially immovable relative to the gear housing in the direction of the longitudinal center axis.

Hand-held power tool which includes a torque clutch

A system includes at least one hand-held power tool and at least one electrotechnical product. The power tool includes a housing with a handle, a drive motor arranged in the housing, and a first interface configured to receive information from at least one second external interface and/or to transmit information to the at least one second external interface. The housing of the hand-held power tool and a housing of the electrotechnical product each have a receiving opening. The first interface is removably arranged in a selected one of the receiving openings. The receiving openings are releasably sealed by corresponding covers. The covers close the housings to the outside.

System formed by at least one hand-held power tool, at least one first interface, and at least one electrotechnical product

A hand-held power tool which includes a gear housing with a gear for transmitting a torque, generated by a drive motor, to a spindle. The gear housing is exchangeably connectable to a tool attachment via an interface in such a way that a torque is transmitted from the spindle to an input spindle of the tool attachment. The interface includes a housing-side interface element with a flange ring, which is connected to the gear housing in a torsionally stiff manner. The housing-side interface element corresponds to a tool attachment-side interface element which includes a fastening ring that is rotatably supported on the tool attachment. The fastening ring is brought into engagement with the flange ring by a coupled rotatory and axial relative movement of the fastening ring with respect to the flange ring so that the fastening ring and the flange ring together form a bayonet-type connector.

Housing for electric and electronic components

A hand-held power tool which includes a shiftable transmission that is shiftable at least between a first gear and a second gear via a shifting member, in which the shifting member is coupled to a spring element, which for the gear shifting is indirectly or directly actuatable at least via a first and a second shifting element. A coupling element which is coupleable to the spring element is associated with the first shifting element, and the coupling element is configured for allowing gear shifting by actuating the first shifting element only for the case that the second shifting element is in a predefined gear shift position.

Hand-held power tool which includes a shiftable transmission

A hand-held power tool includes: a shiftable transmission for driving a drive shaft, which transmission is situated in a gear housing and is shiftable at least between a first gear and a second gear via a shifting member; and a pivotably supported actuating element, which is configured as a bistable spring element and situated, at least in sections, in the area between the shifting member and the gear housing, is associated with the shifting member. The bistable spring element is actuatable for the gear shifting, and assumes a stable shift position in at least one shift position of the shifting member associated with the first or second gear, and assumes an unstable position in an intermediate position of the shifting member which is situated between shift positions of the shifting member associated with the first and second gears.

The invention relates to a machine tool having working field illumination disposed in a housing-having an illumination mechanism and a transparent element which allows the light from the illumination mechanism to be led out toward the working field. A light beam can be deflected between the illumination mechanism and the transparent element. According to the invention, the transparent element forms a region of the housing.

Power tool having a work field lighting system

A device for regulating an increase in the output torque over time of an electric drive motor, including a monitoring unit for monitoring an operating variable of the electric drive motor, a regulating unit for regulating the operating variable for regulating the increase in output torque over time, a control unit for activating the regulating unit as a function of a time derivation of the monitored operating variable, the regulating unit being designed to be deactivated after a predetermined period of time. A method for regulating an increase in the output torque over time of an electric drive motor is also described. A corresponding tool and a computer program having program code for carrying out the method are also described.

Device and method for regulating an increase in the output torque over time of an electric drive motor

The invention describes a hand-held power tool having a drive train, which includes a motor with a rotor, a drive shaft, and a transmission. According to the invention, at least one flywheel mass is provided that is positionable rotationally symmetrical to the drive shaft and connectable to the drive shaft for co-rotation therewith.

The invention relates to an apparatus for positioning and fastening a device, in particular of a handle on a power tool. The apparatus includes a receptacle for the device, which receptacle is adjustable between at least one positioning position and at least one fastening position. The at least two positions of the device are definable by a tension lever. A detent geometry, embodied with the receptacle, cooperates with a receptacle geometry, embodied on or associated with the power tool. Various radial positions of the apparatus relative to the power tool can be set by the detent geometry and the receptacle geometry. According to the invention, it is provided that in addition, an axial securing device associated with the apparatus or the power tool, is provided, which in the positioning position and the fastening position secures the apparatus in its axial position relative to the power tool.
