Abstract: A hand-held treatment system includes: a hand-held treatment device and at least one attachment, wherein the treatment device has a movable treatment part and an electric drive motor system for moving the treatment part. The electric drive motor system has at least one electrical path with at least one interruption. The at least one attachment has a contact bridge. The treatment device and the at least one attachment are configured for the spatial arrangement of the at least one attachment from a hazard position into a safety position, which is different from the hazard position, on the treatment device such that by the at least one attachment being in the hazard position, the at least one contact bridge does not electrically bridge the at least one interruption, and by the arrangement of the at least one attachment in the safety position, the at least one contact bridge electrically bridges the at least one interruption.

Abstract: A hand-held suction system includes: a hand-held suction device, a tube unit and a bag unit, wherein the tube unit has a suction tube and a tube connecting part, and wherein the bag unit has a collecting bag and a bag connecting part. The tube connecting part and the bag connecting part are designed to form a mechanical connection to one another in order to hold the bag unit by way of the tube unit. The tube connecting part is arranged in such a way on a circumference of the suction tube, in an upper half of the circumference in a circumferential direction, in a correct operating position of the suction system, and the suction system is designed in such a way that the bag unit held by the tube unit extends downwards in the circumferential direction along the suction tube, on the upper half of the circumference.

Abstract: A housing for a work implement has a first housing shell with first outer wall and a second housing shell with second outer wall. The first and second outer walls contact each other along a separation plane. The first housing shell has a first rib extending transversely to the separation plane and projecting past the separation plane into the second housing shell. First measuring points are located in the separation plane. The first rib has a first rib height measured in transverse direction from a first measuring point to a first end of the first rib facing the second housing shell. The second housing shell has a second shell height measured in transverse direction from the same first measuring point to an inner side of the second housing shell. The first measuring points include measuring points where the first rib height is at least 15% of the second shell height.

Abstract: The disclosure relates to a handheld work apparatus, wherein the work apparatus includes a housing, a drive motor for driving a tool, and a handle disposed on the housing. A contour is provided on the handle and a counter contour is provided on the housing. In the inoperative position of the handle, a minimum friction torque (M1) which acts about the pivot axis is provided between the handle and the housing. In the operative position of the handle, the contour and the counter contour are operatively connected in such a manner that a further friction torque (M2) which acts about the pivot axis is present between the handle and the housing. The further friction torque (M2) in the operative position is greater than the minimum friction torque (M1) in the inoperative position.

Abstract: A guard for an intake channel or blow channel of a power tool has a first rib with a longitudinal direction, wherein the first rib has a first rib section that extends along the longitudinal direction of the first rib from a first end to a second end of the first rib section. The first rib section has an inherent frequency. One or more first disruptive bodies are arranged on the first rib section between the first end and the second end of the first rib section. The first disruptive bodies are configured to translatorily vibrate together with the first rib section. The first rib section and the one or more first disruptive bodies form a vibration system with a system inherent frequency, wherein the inherent frequency of the first rib section is different from the system inherent frequency.
