  • Patent number: 7553217
    Abstract: A dust-collecting receptacle for an electric hand machine tool, in particular an electric hand grinder, having a dust-collecting chamber (17), an inlet fitting (21), an exhaust opening (18), and a dust filter (20) situated between the dust-collecting chamber (17) and the exhaust opening (18). To achieve a compact design of the dust-collecting receptacle (14) 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 (21), the dust-collecting chamber (17), the dust filter (20), and the exhaust opening (18) are situated one above another and preferably, the form of the dust-collecting receptacle (14) is adapted to the outer contour of the electric hand machine tool (FIG. 1).

  • Patent number: 7475739
    Abstract: A power tool (10) with a housing (12) that includes a dust box (50, 150) and a motor (20) with air cooling, and a cooling exhaust-air duct (44, 46) and a chip suctioning duct (40) 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 (50, 150) under favorable flow conditions, whereby the evacuation of dust into the dust box (50, 150) is improved and whirls of dust caused by cooling air in the tool region are prevented from forming.

  • Publication number: 20080003505
    Abstract: An electrical hand-held power tool is provided, which includes at least one rechargeable battery (16). To attain a compact design of the hand-held power tool with small dimensions, the at least one rechargeable battery (16) is designed as a lithium-polymer rechargeable battery (16) made of metallized plastic foil and a gel-like polymer electrolyte, and is designed with a flat and/or bent and/or spherically curved shape as a single rechargeable element (17) and/or as a component (16?; 16?) composed of several rechargeable elements (17), and is adapted—in terms of dimensions and/or shape—to spaces—which accommodate the rechargeable elements (17)—in the machine housing (11) and/or handle (12) and/or a separate housing (27) which is attached or attachable to the machine housing (11) or handle (12) (FIG. 1).

  • Patent number: 7294300
    Abstract: 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 r

  • Patent number: 7223165
    Abstract: An abrasive pad for a manual grinding machine, in particular for an eccentric grinder, has a flat contact surface (13) on which an abrasive sheet is placed, and attachment means located on the contact surface (13) for creating an adhesive connection with the abrasive sheet. To reduce the production costs of the abrasive pad, it is made entirely—including the attachment means—of plastic using a single-component injection molding procedure, whereby the attachment means are designed preferably as hook-type fasteners (18) which extend out of the contact surface (13) (FIG. 1).

  • Publication number: 20060178087
    Abstract: An electric hand-held power tool is described that has a machine housing (11) with an integral dust-ejection connection (15) and a dust collection container (16) attached thereto. To ensure, when working with the electric hand-held power tool, that the dust collection container (16) is emptied in time when full, a fill level indicator is provided that indicates, at the least, the maximum amount of dust allowed in the dust collection container (16). The fill level indicator (20) is preferably integrated in the machine housing (11) and includes a pressure sensor (21) that measures the pressure in the dust-ejection connections (15), and a display unt (22) that is actuated as a function of the pressure measured (FIG. 1).
