  • Patent number: 8522894
    Abstract: The invention is based on a power tool with at least one handle (10, 26, 50, 62, 104) that comprises at least one grip part (12, 72, 106) that is firmly connected to a mounting part (16, 70, 110) via at least one elastic, vibration-damping element (14, 24, 52, 108), via which the grip part (12, 72, 106) is affixable to a housing (60). It is proposed that the connection between the grip part (12, 72, 106) and the mounting part (16, 70, 110) is secured by means of the elastic element (14, 24, 52, 108) via at least one movable retaining element (20, 22, 28, 64, 112).

  • Patent number: 6641634
    Abstract: A manual machine tool (10) includes a vacuum device for dust removal (19) situated in its housing (12) and a blow-out connection (20) installed after this. A dust collection box (21), particulaily self-contained, can be attached in detachable fashion to the blow-out connection (20) via its blow-in connection (22). The dust collection box (21) is airtight on all but two sides and has air-exit holes (40) on the top side (36) and a dustproof filter element (48)—especially a fluted filter—on the inside. The dust collection box is particularly secure against the unintentional escape of dust after the dust collection box is detached from the associated manual machine tool because a pair of sealing lips (500) arranged as a separate part is provided inside the blow-in connection (22), which pair of sealing lips (500) is connected as a single part with closing flaps (520, 520) projecting into the interior of the dust collection box (210).
