[Object]

The object of the disclosure is to provide a structuring technique which contributes to the rationalization of dispositioning parts and operability with respect to a striking tool in which usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool.

[Embodiment to Achieve the Object]

A striking tool 100 in which striking operation is done in a state that the striking tool 100 is downwardly dropped by the own weight, having a motor 210 with an output shaft to drive the drive mechanism, a controller 260 to control the motor 210, a functional member 280 to assist the striking operation and a controller case 270 to hold the controller 260, wherein the controller case 270 further holds the functional member 280.

A structuring technique contributes to the rationalization of dispositioning parts and operability with respect to a striking tool wherein usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool. A striking tool is held by a pair of handles by both hands while striking operation takes place when the striking tool drops downwardly by the own weight, a drive mechanism drives an end tool in a first direction and motor, wherein the output shaft of the motor extends in a third direction defined as a thickness direction to cross the first direction and the second direction, and a battery mounting portion is disposed at the side region of the main housing in the second direction, wherein a battery to supply electricity to the motor is mounted to the battery mounting portion.

The disclosure relates to a method for sound adaptation, via a sound generator, of a handheld work apparatus driven by an electric drive motor and to a handheld work apparatus with a sound generator configured for this purpose. The work apparatus generates during operation an uncorrected operating sound. Via the sound generator, during operation a supplementary sound is generated in addition to the uncorrected operating sound and is overlaid on the operating sound to form an overall sound with an overall sound pressure level (LG.sub.p). In this case, the main component of the supplementary sound lies in an adaptation frequency spectrum (f.sub.A) below 1 kHz.

A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

A tool includes a tool head with a utilization surface. The tool also includes a counter device responding to an impact applied to the utilization surface. The counter device has a memory, a microcontroller controlling operation of the counter device, an indicator, and an energizer connected to the microcontroller, which in response to the impact applied to the utilization surface, produces an electric current energizing the counter device to make a modification in the memory and provide information about the cumulative count of impacts in the memory via the indicator to a user.

A work tool includes a motor, a driving mechanism, a body housing and a handle. The driving mechanism is configured to perform an operation of linearly reciprocating the tool accessory along a driving axis extending in a front-rear direction. The handle includes a grip part extending substantially in an up-down direction, and a battery-mounting part provided on a lower side of the grip part. An upper end portion of the handle is connected to a rear end portion of the body housing via an elastic member so as to be movable relative to the body housing. A lower end portion of the handle is connected to the rear end portion of the body housing so as to be rotatable relative to the body housing, around a rotation axis extending in a left-right direction. The rotation axis is located on a lower side of the battery-mounting part.

A percussion tool includes a housing having a top end, a bottom end, a front end, and a rear end. The housing defines a barrel portion, a handle portion opposite the barrel portion, and a motor housing portion between the barrel portion and the handle portion. The percussion tool also includes an electric motor positioned within the motor housing portion and a percussion mechanism driven by the motor and including a striker supported for reciprocation in the housing. The striker defines a striker axis in a reciprocating direction. The percussion tool further includes a battery receptacle supported by the housing and a battery pack removably coupled to the battery receptacle for providing power to the motor. The battery pack and the battery receptacle define a battery axis extending longitudinally through the battery pack and battery receptacle. The striker axis and the battery axis are parallel.
