Abstract: A portable power tool, in particular an angle grinder (10), with a longitudinal housing (12) for accommodating a motor for driving a driven shaft (16) that is U-bent relative to the housing (12), the driven shaft being rotatably supported in a gearbox casing (14) and extending out of it with a free end that is provided to accommodate a sanding body, whereby a protective cover (43) encompassing the sanding body is capable of being fastened on the gearbox casing (14) such that its rotation can be adjusted, and the rotational position of which is lockable using a notch lever (30), is made safer to operate and more cost effective to manufacture by the fact that the notch lever (30) is positioned transversely to the longitudinal axis of the angle grinder (10) and is pivotable around an axis (34) positioned substantially parallel to the housing (12).

Abstract: An electric hand power tool has an on/off switch, an elongated switching key having a front end and a rear end and actuating the switch, a blocking lever carried by and projecting from the switching key to prevent or to allow turning on of the latter, the switching key being supported turnably, the switching key having a convex curvature starting substantially centrally and extending toward the rear end, the switching key carrying the blocking lever near the rear end, the blocking lever having an upper edge located under a tangent between the convex curvature and the rear end of the switching key.

Abstract: An angle grinder with a housing 2 can be produced more economically by providing that it has a mounting shell 3, a cap shell 4, and an insert part 1 between these two shells. The insert part 1 is equipped with a first fixation device 10 and a second fixation device 11 for fixation between the mounting shell 3 and the cap shell 4, and it has a spindle locking receptacle 12 and spindle bearing receptacle 13. The mounting shell 3 has a first fixation means 30, which is engaged by the first fixation device 10 of the insert part 1. The cap shell 4 has a second fixation means 40, which engages the fixation device 10 of the insert part 1. The insert part 1 also has a second fixation device 11, which can be brought into engagement with suitable means on the mounting shell 3 and the cap shell 4.

Abstract: A protective hood (1) for a right-angle grinder having a tightening device, which has a tightening band (4) firmly connected to the protective hood (1) for a right-angle grinder, the two ends (5, 6) of the tightening band being embodied as a first and second eyelet (7, 8), so that they form a first and second abutment (9, 10) and can be connected to one another under tension by means of at least two tightening elements, the first tightening element being a tightening lever (2), which with its first end (15) can be supported in the first eyelet (7) pivotably about a first axis (9a) and which can be brought into a first position in which the tightening device is not tightened, and into a second position in which the tightening device is tightened, becomes capable of being produced at less expense with still high quality by providing that the second tightening element is a spring (3), which can be connected movably to the tightening lever (2), the spring (3) being pivotably supported about a second axis (11) in

Abstract: A power tool (10), in particular an angle grinder, having a housing (12) that receives an electric motor (21) and a gear (26), the motor (21) having a rotor (210) which is guided in rotor bearings (2100) and on one hand carries a collector (2102), which collector can be put into contact with a voltage source via carbon brushes (23) supported in brush plates, is made sturdier and easier to install in that the housing (12) comprises two longitudinally split housing shells (120, 121), and that the brush plates are part of a bearing bridge (24) that carries both the rotor bearing (2100) and the carbon brushes (23), and the bearing bridge (24), in the guide region of the carbon brushes (23), comprises plastic.

Abstract: An electric hand power tool has an on/off switch, an elongated switching key having a front end and a rear end and actuating the switch, a projecting blocking lever which manually sets a turning on lock out of operation, the switching key being supported turnably, the switching key having a concave curvature starting substantially centrally and extending toward the rear end, the switching key carrying the blocking lever near the rear end.

Abstract: A hand belt sander has a housing, a drive roller and a deflecting roller both rotatably supported in the housing, the deflecting roller being arranged at a distance from the drive roller movable between a substantially axes-parallel arrangement and out of the axes-parallel arrangement with the drive roller, an endless sanding belt guided along the rollers, a guide plate located in the housing and carrying a control plate with an end for receiving the deflecting roller and being displaceable together with the control plate, a lever arm sensing a position of the sanding belt by a stop part and acting on the position of the sanding belt, a swivel arm around which the lever arm is swivelable and which extends perpendicular relative to the guide plate. The swivel arm sits in the guide plate. The control plate is swivelable around the swivel axle together with the ends and extends toward the guide roller so as to form the swivel arm in a one-piece element, and also carries the stop part.

Abstract: The power driven, hand operated plane of the type having a fixed front guiding plate adjoining the circular path of movement of the planing knife, and a vertically adjustable rear guiding plate controlled by an adjustment device assembled of a control disk mounted at one end of a screw spindle and projecting partially from the housing; the other end of the spindle engages a nut which is secured to the shoe by a preadjustment mechanism; a biasing spring presses the shoe against the nut; a dial provided on top of the control disk is visible to the user through a window in the housing.
