Patents by Inventor Felix Oberhofer

Felix Oberhofer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11958155
    Abstract: The invention is directed to a handheld work apparatus having 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°.
    Type: Grant

  • 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).
