  • Patent number: 11310959
    Abstract: A tool head for a hand-guided implement possesses two rotatably mounted tools, wherein a first tool is drivable via a first linkage and a second tool is drivable via a second linkage. The tools are drivable so that they rotate back and forth in opposite directions about a common rotational axis. The first linkage possesses a first drive member coupled to a first coupling member pivotably about a first link axis. The first coupling member is coupled to the first tool pivotably about a second link axis. The second linkage possesses a second drive member coupled to a second coupling member pivotably about a third link axis. The second coupling member is coupled to the second tool pivotably about a fourth link axis. The rotational axis of the tools and the coupling drive axis span a center plane, which runs between the second link axis and the fourth link axis.

  • Patent number: 10434586
    Abstract: A handheld work apparatus has a motor unit, a tool unit and an outrigger having a carrier part. The outrigger connects the motor unit to the tool unit. The carrier part has a base plate having an inner side and an outer side. A drive shaft and a driven shaft are arranged transversely to the base plate. The carrier part has a first stiffening structure, which rises from the inner side of the base plate toward a space diagonal. On the outer side of the base plate, a second stiffening structure rises toward the same space diagonal, wherein the first stiffening structure and the second stiffening structure conjointly form a spatially diagonally running stiffening element.

  • Patent number: 8397389
    Abstract: A power tool has a drive motor and first and second tool members driven reciprocatingly by the drive motor in opposite directions, respectively. The first tool member is driven by a first connecting rod and the first connecting rod is connected to the first tool member by a first pivot joint arranged on the first connecting rod. The second tool member is driven by a second connecting rod and the second connecting rod is connected to the second tool member by a second pivot joint arranged on the second connecting rod. The first pivot joint is arranged on an end of the first connecting rod which end is facing the tool members. The second pivot joint is arranged on an end of the second connecting rod which end is facing away from the tool members.
