Abstract: The invention relates to a protective hood anti-rotation lock for a portable power tool (12a-f), especially for an angle grinder, for providing anti-rotational locking between the portable power tool and a protective hood unit (14a-f). According to the invention, the protective hood anti-rotation lock has a non-positive unit (16a-f) which is provided for anti-rotational locking of the portable power tool (12a-f) and the protective hood unit (14a-f) in the event of a tool (18a-f) breakage.

Abstract: The invention relates to a protective hood securing device for a portable power tool (12), especially an angle grinder. Said protective hood securing device comprises a protective hood unit (14), having a protective hood (16), and a securing unit (18) having at least one securing element (20) which is provided together with the protective hood unit (14) for protection in the event of a tool (22) breakage. For this purpose, the securing element (20) is at least partially configured by a protective cover (24) that is provided in addition to the protective hood (16).

Abstract: The invention relates to a portable power tool for a rotating, preferably disk-shaped tool (12). Said portable power tool comprises a machine housing (14), having a flange (16, 160) or a machine neck, and a protective hood (18) that can be detachably tensioned on the machine neck to cover the tool (12) or that has a protective hood neck (20) or protective hood collar that annularly carries a tightening strap (22). Said strap can be tightened by tensioning means (24). An anti-rotation lock effective between the machine neck and the protective hood (18) is interposed between the protective hood (18) and the machine neck in the form of a profiled structure (26). The invention is characterized in that the tensioning means (24), in its tensioned position, can be connected several times in a form fit to the machine neck and in its detached positioned is no longer connected in a form fit to the machine neck.

Abstract: The invention relates to a protective hood anti-rotation lock for a portable power tool (12a-e), especially an angle grinder. Said protective hood anti-rotation lock is characterized in that it comprises an anti-rotation unit (14a-e) that is adapted to take into consideration at least one operating parameter of the portable power tool (12a-e) during anti-rotational locking.

Abstract: The invention relates to a protective hood for a portable tool with a rotary tool, having an axial wall for covering regions of the rotary tool. It is proposed that the axial wall (3) have wall regions (4) which are axially offset from one another and are connected to one another, in particular in one piece. Furthermore, a portable tool is proposed which has such a protective hood (1).

Abstract: The invention relates to a protective hood for a portable tool with a rotary tool, having a clamping device designed as a clamping ring for fastening to a machine neck of the portable tool, and having an anti-rotation locking means for fixing the angular position of the protective hood relative to the portable tool. It is proposed that at least one rotation-locking element (19) which can interact with a rotation-locking element (19) of the machine neck be arranged in a fixed position on the clamping ring (7) for forming the anti-rotation locking means. A portable tool having such a protective hood (1) is also proposed.

Abstract: A band sander has a motor housing (2) and a band running case (17) located below the latter, the abrasive band revolving therein. The abrasive band is driven via a belt (17) and belt wheels (14, 16). Because of manufacturing tolerances, it is necessary to be able to adjust the belt tension in a simple manner after the device has already been assembled. This is effected by an insert plate (19) which is inserted into a slot (18) between the motor housing (2) and band running case (7) so as to be displaceable. The insert plate (19) has steps (31 to 33) of varying height which determine the distance between the motor housing (2) and band running case (7) and accordingly determine the belt tension.

Abstract: A manual milling machine comprises a motor housing, a foot plate adapted to be placed on a workpiece and having a central opening, a milling tool extending through the central opening, a tool receptacle provided on the lower side of the motor housing, a guiding sleeve which surrounds the milling tool and extends in the mounted condition beyond the foot plate, and an assembly for connecting the guiding sleeve with the foot plate. The connecting assembly includes a plug connection provided on the guiding sleeve and a bayonet lock connecting the plug connection with the foot plate.

Abstract: A routing machine has a motor housing with a lower side having a tool receptacle for a milling tool, a foot plate adapted to be placed on a workpiece, guiding columns extending perpendicularly relative to the foot plate, the motor housing being arranged displaceably on the guiding columns parallel to an axis of the milling tool, a clamping sleeve having a clamping screw and releasably fixing the motor housing on at least one of the guiding columns, at least one spring supporting the motor housing on the foot plate, an adjusting member axially displaceable relative to the clamping sleeve over a thread and supports a weight of the motor housing. The spring has an upper end abutting against the adjusting member. The motor housing is supported relative to the adjusting member on bearings and is fixed in an axial direction of the guiding column at both sides.
