  • Patent number: 10953533
    Abstract: A manually guided implement possesses a guide tube, wherein a first mass body is disposed on a first end of the guide tube, and a second mass body is disposed on a second end of the guide tube. One of the mass bodies has a housing, and the other of the mass bodies has a tool driven by a drive motor. A power transmission mechanism for driving the tool between the first and second ends of the guide tube is guided in the interior of the guide tube. A first antivibration element is disposed between the first end of the guide tube and the first mass body. The guide tube in the direction of the longitudinal central axis thereof includes a first rigid sub-portion and a second rigid sub-portion that are connected to one another at an abutment location by at least one second antivibration element.

  • Publication number: 20180023680
    Abstract: A work apparatus has a gear unit which is arranged in a gear housing. The gear unit includes a drive part arranged in a first housing part of the gear housing and an output part arranged in a second housing part. The two housing parts are connected to each other via a pivot joint which permits pivoting of the second housing relative to the first housing part about a pivot axis. The pivot joint has a clamping device for bracing the two housing parts in the direction of the pivot axis. The force exerted with the clamping device on the two housing parts is adjustable via a clamping element. To avoid loosening or releasing of the clamping device even after frequent pivoting, the clamping element moves during clamping in the direction of a clamping axis which encloses an angle ? which is more than 10° with the pivot axis.
