The invention relates to a device for cleaning vehicle wheels that contains a rotary body driven rotationally by a drive motor about a central axis, with cleaning elements arranged on its front end face. An improved cleaning can be achieved by virtue of the fact that the rotary body contains at least one rotary plate equipped with additional cleaning elements that is rotated by the rotation of the rotary body, not only about the central axis but also, via a gear assembly, about its own longitudinal axis.

The invention describes a handle for a hand-held machine tool comprising a grip element () and a fastening element () for fastening the handle to a housing of a hand-held machine tool, wherein the fastening element () partially protrudes into the grip element () and a damping element () is provided between the grip element () and the fastening element (), and wherein the fastening element () forms an undercut () in the grip element ().

Handle for a hand-held power tool

A quick-action chuck, in particular for a power tool, has an actuating element () and a control device which includes at least one mechanism () for controlling at least one locking device () that serves to absorb a chucking reinforcement force via the locking device () that is controllable by the control device, a positive-engagement connection can be brought about for absorbing the chucking reinforcement force.

Quick-action chuck

A handheld power tool, in particular a handheld right-angle grinder (), has an electric motor drive for a motor housing () that accommodates a tool and also has a handle (), which is retained on the motor housing () by means of a handle mounting device () located between them, which handle mounting device has a mount (), fastened to the motor housing (), and at least one vibration-damping element () that is in communication with the mount () and the handle (). The handle mounting device () has a mounting plate (), on which the handle () is fastened by means of a fixation device. The at least one vibration-damping element () is located between the mount () and the mounting plate () and is solidly joined to them to form a unitary component. Fastening members () engaging the mount () are provided, which fix the mount () to the motor housing () and are provided with securing elements () that are free-standing relative to the mounting plate () and that, if the vibration-damping element () is torn, firmly retain the mounting plate () along with the handle () mounted on it (FIG.).

A power scroll saw with a housing and a saw blade capable of being driven in a reciprocating manner, and with tongs-like guides that guide the saw blade in a laterally-supported manner is capable of being used in a variety of work applications due to the fact that the guide means are capable of being switched by hand selectively into a position having lateral clearance from the saw blade and into a position in which they laterally support the saw blade.

Hand-operated jig-saw with saw blade guidance system

A hand-guided saber saw, has a drive unit by way of which a tool, in particular a saw blade, can be driven, and with a tool guide mechanism, by way of which the tool can be guided laterally by guide elements, and the tool guide mechanism has a control motor, by way of which a spacing between the guide elements can be adjusted to a tool thickness, and the tool guide mechanism has pivot arms, connected via a joint, on which arms the guide elements are disposed.

The chain tension of a motorized chainsaw ( ) with a housing ( ), a sprocket ( ) mounted thereon, and a blade ( ) that is aligned with this sprocket, which blade protrudes beyond the housing ( ) and guides a saw chain ( ) engaged with the sprocket ( ) in a revolving manner, where the blade ( ) is mounted such that it can be adjusted by means of longitudinal displacement in relation to the housing ( ) and/or the sprocket ( ) by means of a chain tensioning device ( ) and where the chain tensioning device ( ) has a stop ( ) that can be fixed to the blade ( ) and a cam ( ) that can be rotated by means of a rotational member ( ) can be adjusted in a more comfortable and reliable fashion by virtue of the fact that the cam ( ) can be locked in a form-fitting and rotationally secure manner in relation to the housing ( ) by way of the rotational member ( ).

Chain saw

A hand-guided power jigsaw ( ) having a jigsaw blade ( ) which can be detachably clamped between the free ends ( ) of two essentially parallel-arms ( ) that are preferably comprised of a U-shaped frame ( ), in particular comprised of a tube, and which can be driven, in particular in a reciprocating manner, by a motor built into the jigsaw ( ), wherein a laterally protruding handle ( ) with a switch button ( ) is disposed on the front of the free end of one of the arms ( ), is particularly maneuverable and easy to produce since the lower arm ( ) has a, base housing ( ) attached to it, which is embodied in the form of a pistol and protruding obliquely back and down from underneath the housing ( ), has a handle ( ) whose rear contour toward the base housing ( ) forms a curved, angled throat ( ), which rests in the hand of the user in a horizontally and vertically supported fashion.

A drilling or chiseling tool includes a suction apparatus (8) releasably mounted on a housing (1) of the tool. The suction apparatus (8) contains a replaceable separating device (11) formed of a housing (13) subdivided into two separate chambers (K1, K2) by a filter element (14) replaceably fitted in the housing. Each chamber (K1, K2) has an aperture (12, 15) and the cross-sections of the apertures extend at right angles to one another.
