The invention relates to a hand machine tool comprising a first housing shell (), a second housing shell () different from the first housing shell () and being connected to the first housing shell () via a damping element (), and a handle section () arranged on one of the housing shells (). The invention is characterized in that the first housing shell () at least partially encloses the second housing shell ().

Hand-held power tool

The invention is based on a hand-guided sander having a housing () whose size is essentially limited to that of a base () of a sanding plate (). According to the invention, the housing () is equipped to accommodate a rechargeable battery unit (). The invention also relates to a sander cradle and a sander housing.

Hand-guided sander, sander cradle, and sander housing

A housing device for a hand-held power tool has at least one see-through region composed of a transparent plastic, and having an interior side configured as a carrier for an element selected from the group consisting of an information element, a signal element, and both; and also a hand-held power tool is provided with such a housing device.

In a rolled product dispenser, when the rolled product is unrolled, a simple, quick punching of required holes in the rolled product and a simultaneous cutting to length are achieved by virtue of the fact that the rolled product dispenser has a hole punching and cutting device.

Rolled goods dispenser

A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (), an inlet fitting (), an exhaust opening (), and a dust filter () situated between the dust-collecting chamber () and the exhaust opening (). To achieve a compact design of the dust-collecting receptacle () that on the one hand, does not impair operation of the electric hand grinder or only does so to an insignificant degree and on the other hand, has a high dust-collecting efficiency, the inlet fitting (), the dust-collecting chamber (), the dust filter (), and the exhaust opening () are situated one above another and preferably, the form of the dust-collecting receptacle () is adapted to the outer contour of the electric hand machine tool (FIG.).

Dust-collecting container for a hand electric machine tool

A power tool () with a housing () that includes a dust box () and a motor () with air cooling, and a cooling exhaust-air duct () and a chip suctioning duct () which guides a chip-suctioning flow can be used with improved performance and in an environmentally friendlier manner due to the fact that the cooling air flows across the dust box () under favorable flow conditions, whereby the evacuation of dust into the dust box () is improved and whirls of dust caused by cooling air in the tool region are prevented from forming.

A grinding plate for an electric hand grinder has a plate member having an upper plate surface with an upper plate edge, a lower plate surface with a lower plate edge for placement of a grinding means and extending at least partially beyond the upper plate edge, and a side surface extending from the upper plate edge to the lower plate edge, and having a pagoda-shaped contour in a projecting region of the lower plate edge and the grinding plate is produced by a method including punching out the plate body with the upper surface, the lower surface and the side surface from an elastic material in a desired shape; placing a round bar on the upper plate surface along the upper plate edge of the plate body with a parallel distance from it; pressing the round bar into the plate body so that an elastic material of the plate body is squeezed outwardly under the round bar; separating the squeezed out material along an outer edge of the round bar with a separating cut extending perpendicular to the plate surfaces; and removing the round bar from the upper plate surface.

Dust collector

An abrasive pad for a manual grinding machine, in particular for an eccentric grinder, has a flat contact surface () on which an abrasive sheet is placed, and attachment means located on the contact surface () for creating an adhesive connection with the abrasive sheet. To reduce the production costs of the abrasive pad, it is made entirely&#x2014;including the attachment means&#x2014;of plastic using a single-component injection molding procedure, whereby the attachment means are designed preferably as hook-type fasteners () which extend out of the contact surface () (FIG.).

Abrasive pad for a manual grinding machine

The invention is based on a hand power tool that comprises a motor ()&#x2014;with a motor shaft&#x2014;located in a housing (), which said motor shaft is supported via a shaft bearing () located on a side closest to a backing pad () and that is interconnected in torsion-resistant fashion with an eccentric sleeve () in a seat (). It is proposed that the eccentric sleeve () projects in the axial direction () at least partially into the shaft bearing (), and at least part of the axial space of the shaft bearing () is used to form a drive connection with the eccentric sleeve ().

Hand-held machine tool

A hand power tool (), in particular with integrated dust removal, that comprises a housing () on which a dust tube () is mounted that is capable of being interconnected with a dust box () by means of its dust inlet connection piece (), whereby a side wall () of the dust box () has through holes () that are reached over by a filter in dust-tight fashion, becomes less expensive and more environmentally friendly by the fact that the filter () is formed by a flat sheet composed of a fine-pored material, the surface area of which is increased by means of certain structures.

Handheld sander

An electrical power grinder, in particular an eccentric grinder, is disclosed that has a grinding wheel () and a grinding-medium holder (), held on the underside thereof, of soft material. For the sake of reducing wear of the grinding-medium holder () at its outer edge and lengthening the service life of the grinding-medium holder, the grinding wheel () is provided with an edge guard, which has a guard member () encompassing the grinding wheel () that protrudes, in the plane of the grinding wheel, past the outer contour of the grinding-medium holder () (FIG.).

A tool fastening mechanism has a housing , in which a clamping opening is embodied for receiving a tapering tool shaft clamping end of a tool part . The clamping opening tapers inward in the introduction direction of the clamping end of a tool part , and furthermore the tapering sides are inclined toward one another in a plane extending perpendicular to the introduction direction, as a result of which the opening has a trapezoidal cross section, and the length of this cross section decreases away from the orifice of the clamping opening . The housing furthermore has a transverse opening , which intersects the clamping opening and in which a locking pin is received. Upon introduction of a tool into the fastening mechanism, a tapering edge of the pin comes into engagement with a front edge of an oblong hole , embodied in the clamping edge of the tool part , and the resultant engagement action draws the clamping end deeper into the clamping opening , while the pin is driven farther into the transverse opening . The combination of the double tapering of the clamping opening and the longitudinal locking accomplished by the locking pin makes it possible to effectively restrict all six degrees of freedom of the tool part, within the production tolerances attainable by conventional mass-production methods.
