Housing for electric and electronic components

A hand-held power tool which includes a shiftable transmission that is shiftable at least between a first gear and a second gear via a shifting member, in which the shifting member is coupled to a spring element, which for the gear shifting is indirectly or directly actuatable at least via a first and a second shifting element. A coupling element which is coupleable to the spring element is associated with the first shifting element, and the coupling element is configured for allowing gear shifting by actuating the first shifting element only for the case that the second shifting element is in a predefined gear shift position.

Hand-held power tool which includes a shiftable transmission

A hand-held power tool includes: a shiftable transmission for driving a drive shaft, which transmission is situated in a gear housing and is shiftable at least between a first gear and a second gear via a shifting member; and a pivotably supported actuating element, which is configured as a bistable spring element and situated, at least in sections, in the area between the shifting member and the gear housing, is associated with the shifting member. The bistable spring element is actuatable for the gear shifting, and assumes a stable shift position in at least one shift position of the shifting member associated with the first or second gear, and assumes an unstable position in an intermediate position of the shifting member which is situated between shift positions of the shifting member associated with the first and second gears.

The invention relates to a grinding disk for an eccentric grinding machine. In order to operate the grinding disk () having different disks diameters on one and the same eccentric grinding machine for achieving grinding results at optimum quality, without any loss of smoothness and handling quality, the disk mass of the grinding disk has a fixed predetermined value that is independent of the disk diameter selected.

Tool set for an eccentric grinder

An eccentric grinder has a drive which is arranged in a housing and the drive shaft of which drives a supporting shaft of a back-up pad by way of an eccentric mounting. Also provided is a friction braking device, which comprises a friction braking element on the housing and a friction surface on the back-up pad. The friction surface slopes down in the radial direction from the inside to the outside with respect to a horizontal plane that is perpendicular to the axis of rotation of the back-up pad.

Eccentric grinder

Portable sander, in particular an orbital sander, having an abrasive sheet carrier () and having clamping means () for firmly clamping opposite abrasive sheet ends of an abrasive sheet () which can be supported on the abrasive sheet carrier (), wherein first clamping means () together with an abrasive sheet end clamped thereon can be moved away from the other abrasive sheet end, clamped by means of second clamping means (), for tensioning the abrasive sheet (), and the first clamping means () have spring elasticity. Provision is made for the first clamping means () to come against a rigid stop element () with prestress in an end clamping position.

Power sander with novel sanding sheet tension clamping

A hand-held machine tool has an electric drive motor (), arranged in a housing (), for driving a tool (), wherein a dust collecting container () is connected to the housing and has in its wall a container connector (), which can be pushed axially onto a blow-out connector () in the housing. When the connection is disconnected, the wall () of the dust collecting container and an assigned wall () on the housing are in contact by way of at least one common supporting point, wherein the supporting point is displaced in the axial direction when the dust collecting container rotates about a longitudinal axis () of the container connector.

Hand-guided machine tool

The present invention is based on a hand-held power tool with a housing (), an oscillating body () provided for oscillation relative to the housing (), and connecting means () which fasten the oscillating body () to the housing (). It is provided that the connecting means () include a receiving part () which can be installed in the housing () and an oscillating element () which is separate from the receiving part () and is provided for deformation.
