  • Publication number: 20240261921
    Abstract: A handheld work apparatus includes a work tool. The work apparatus defines a longitudinal plane and includes a handle having a longitudinal axis. The blocking lever is mounted so as to be pivotable about a rotational axis. The blocking lever blocks the actuating lever in a blocking or disable position and enables the actuating lever for actuation in at least one operating enable position. In the direction of view perpendicular to the longitudinal plane, the longitudinal axis of the handle and the rotational axis of the blocking lever conjointly define an angle (?). The angle (?) lies in a range of from 10° to 60°.

  • Publication number: 20240260798
    Abstract: A handheld blower apparatus includes a handle, a blower tube, a blower unit arranged in the tube, and has an intake opening and a discharge opening. The blower unit has a blower wheel rotationally driveable about a rotational axis aligned in the direction of an air flow flowing out from the wheel during operation. The wheel is driven by an electric motor supplied with energy by a battery. A handle opening extends between the handle and tube. A central plane intersects the handle and battery and contains the rotational axis. A compact, ergonomic arrangement is achieved when the battery and the handle are arranged on opposite sides of the tube and the top side of the tube, when viewed in the direction perpendicular to the central plane, has an indentation extending over at least 50% of the length, measured parallel to the rotational axis, of the handle opening.

  • Patent number: 9689126
    Abstract: An assembly includes a handheld work apparatus and a support. The support has a holder worn by an operator and a connector arrangement which is held at a first attachment on the holder and on a second attachment on the work apparatus. The connector arrangement is mounted on the second attachment so as to be pivotable about a pivot axis and supports the work apparatus in a rearward direction in relation to the operator and prevents a rearward movement of the work apparatus. The center of gravity of the work apparatus and the first attachment have a spacing (a) to one another measured in a horizontal and lateral direction in relation to the operator. The holder has, at the first attachment, a bracing device for supporting the tilting moment acting on the first attachment by the weight force (F) of the work apparatus because of the lateral spacing (a).
