  • Patent number: 11543898
    Abstract: A hand-guided treatment device is configured for use in working positions tilted relative to each other by a tilt angle of at least 45° about a device longitudinal axis. The device has a device housing, a handle operating unit with a handle extending with a main direction component parallel to the device longitudinal axis and a finger-operable operating element within finger reach of the handle, and a display field arranged on an outside of the device housing with at least one optical display element. The display field is arranged offset relative to the operating element in a housing circumferential direction about the device longitudinal axis and extends in the housing circumferential direction over a housing edge and/or with a curved or kinked course.

  • Publication number: 20220297211
    Abstract: A handheld portable cutting apparatus has a cutter unit with a cutter unit longitudinal axis. In a central housing section of the cutting apparatus, a drive connection is arranged between an electric drive motor and the cutter unit, wherein a motor housing having a motor housing longitudinal axis extends from the central housing section. A handle extends from the central housing section in a handle longitudinal axis. The cutter unit includes a guide bar with a saw chain circulating thereon, wherein, in a side view onto the cutting apparatus, the point of intersection between the handle longitudinal axis and the motor housing longitudinal axis and also the point of intersection between the handle longitudinal axis and the cutter unit longitudinal axis lie in the central housing section.
