A work apparatus has a tool, which can be driven in a rotating manner around a rotational axis. The work apparatus has a protective hood extending over at least a part of the periphery of the tool. The protective hood is attached to a housing part of the work apparatus. At least two rotation locks for the protective hood are arranged in different angular positions around the rotational axis. Each rotation lock is formed by virtue of the fact that one of the components of the protective hood and the housing part has a protruding section cooperating with a section of the other component of the protective hood and the housing part and securing the protective hood on the housing part in a positive-locking manner against rotation around the rotational axis, so that the protective hood is prevented from moving with respect to the housing part around the rotational axis.

Work apparatus

A handheld work apparatus includes a housing and a work tool arranged on the front end. The housing has a back end to which an operator region is assigned. The housing has a first and a second shell separable in a separation direction. The operator region, in the region of the back end, is bounded by a tubular section of an outer housing wall. The outer wall of the first shell is reinforced in the region of the tubular section by a rib structure inside the housing. In a view in the separation direction of the inner side of the first shell, in the region of the tubular section, the first shell has an interconnected rigid rib region and an interconnected elastic expansion region. The expansion region is directly adjacent to the rib region and is at a greater distance from the back end than the rib region.

Handheld work apparatus

A handheld apparatus includes a handle at least partially engaging around a housing. The housing extends along a longitudinal axis from the back to the front end. The apparatus possesses a longitudinal plane which in a storage position runs perpendicular to the horizontal plane and contains the longitudinal axis. An operator-control region has a handle opening penetrating fully through the housing in the direction transverse to the longitudinal plane. The handle opening has in the direction of the longitudinal axis a distance point with the largest distance to the back end. The operator-control region extends in the direction of the longitudinal axis from the back end up to the distance point. The housing possesses an imaginary tangential plane which is only tangent to the housing, runs perpendicular to the longitudinal plane and is tangent to the handle. The imaginary plane is tangent to the housing in the operator-control region.

Handheld, battery-operated work apparatus

A cell holder structure for holding a plurality of battery cells includes a holder base part and a holder cover part forming an array of cell-receiving spaces and cell intermediate spaces lying inbetween. The holder base part has one or more base side cell supporting pillars extending axially from a base plane of the holder base part into cell intermediate spaces and has a circumferential side securing wall region abutting in an axially and radially position securing manner against a circumferential surface of battery cells to be accommodated in the cell receiving spaces, and/or the holder cover part has one or more cover side cell-supporting pillars which extend axially from a cover plane of the holder cover part into the cell intermediate spaces and have a circumferential side securing wall region abutting in an axially and radially position securing manner against a circumferential surface of the rechargeable battery cells.
