  • 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: 6112632
    Abstract: The cutting member for a saw chain of a motor chainsaw has a base body with a rear portion and a leading portion in a cutting direction of the cutting member. The rear portion and the leading portion extend in the center plane. The base body has rivet openings. The cutting tooth is formed at the rear portion and the depth limiter is formed at the leading portion. The leading portion has a support stay formed by bending at a bending line an upper end portion of the leading portion in a direction out of the center plane. The free end of the upper end portion is bent in a second direction opposite the first direction back across the base body to form an overhang. The overhang has a forwardly and downwardly slanted surface facing away from the base body. The overhang has a length in the cutting direction that is smaller than the width of the support stay. The support stay has a stay edge facing the cutting tooth. The overhang edge has a greater spacing to the cutting tooth than the stay edge.
