Definitions

  • the invention relates to a hand tool according to the preamble of claim 1.
  • angle grinder with approximately at right angles to the housing axis angled arranged, rotating tool known, which may also be a einspannbares brush tool.
  • the hand tool of the invention with the characterizing features of claim 1 is compared to known hand tool significantly easier to handle, especially when ambidextrous guiding with high operating force with inserted brush tool, because by the doubly bent arrangement of the housing ends they are so securely clamped in the hands of the operator that this ensures a very effective guiding and working in various holding positions.
  • the tool receiving portion of the housing at the bend has a sidecut, the fingers of the operating hands are given a particularly secure, defined hold.
  • the operating hands have a large-scale fitting, comfortable grip.
  • the grip on the housing is further improved, wherein the annular bead on the tool receiving, bent portion of the housing near the tool holder unwanted touching the brush tool by prevents the operator's hand and improves work safety.
  • the power tool has a snap-on clamping device for replaceable brushes of different sizes and shapes, a universal use with rapid brush replacement is secured.
  • the clamping device is releasable by means of a button, the tool change is quick and easy.
  • the key is formed from a region of the annular bead, it is particularly easy to reach by the hand of the operator.
  • the housing is made in shell construction, the both ends kinked housing torsion and bending resistance and easier to install than in pot construction.
  • the illustrated in Figure 1 in longitudinal section as electric brush 10 hand tool has a housing 12 which extends centrally approximately cylindrical elongated as the housing main body 12a and the two ends longitudinally down at an angle of approximately 45 ° as the front and rear bend 28, 30 is configured ,
  • the housing main part (12a) includes an electric motor 14 which is rotatably connected via a gear 16 to an output shaft 18.
  • the output shaft 18 receives a replaceable plug-brush tool 20 for rotational drive on a rotationally clamped.
  • the brush tool 20 carries a shaft-like insertion end which is rotatably locked in a non-descript clamping device of the output shaft 18, captive plugged.
  • the gear housing 12 In its straight central region, the housing main part 12a, the gear housing 12 carries on its upper side a switching slide 22 for actuating an electric switch for switching on and off the electric motor 14.
  • a bottom emerging from the rear end 30 electric cable is the power supply of the electric motor fourteenth
  • a setting wheel 25 of an electronic speed control is arranged at the end of the rear bend 30 of the housing 12.
  • the housing main part 12a passes into the front, downwardly directed bend 28, wherein in the region of the bend 28, the upper side of the housing 12 is configured as a knee-like ball region 26.
  • the front bend 28 is at the bottom, at its free end adjacent to the coupling region of the brush tool 20 in an annular bead 34 via.
  • the annular bead 34 serves to support the guide hand of the operator and should prevent slippage of the hand to the brush tool 20 out.
  • a segment region of the annular bead 34 is configured as a pushbutton 32 with which the clamping device, which is not described in more detail, can be released by pressing down, so that the brush tool 20 can then easily be removed.
  • a waist 36 is formed, which gives the power tool 10 a particularly good grip.
  • the housing 12 On the underside opposite the ball area 26, the housing 12 has a concave-shaped indentation 38, which continues laterally in each of the housing shells 11 and 13 (FIG. 2) in waist-like indentations 38 ', 39.
  • FIG. 2 shows a plan view of the embodiment of Figure 1, wherein particularly clearly the switching slide 22 at the top of the housing main body 12a, the housing shells 11, 13 of the housing 12, the ball area 26, the waist 36, the waist-like indentations 38 ' , 39, the front bend 28, the annular bead 34, the push button 32 and the rear bend 30 can be seen.
  • FIG. 3 The further exemplary embodiment of an electric brush 50 shown in FIG. 3 corresponds in principle to that according to FIG. 1, with only the waist-like indentations 78, 79 adjoining its ball region 66 differing from the previous exemplary embodiment.
  • FIG. 4 differs from the preceding embodiments by a slightly longer portion of the front bend 108 without waist-like indentations and by a pistol grip-like shaped rear bend 110th
  • FIG. 5 shows the electric brush 10 according to FIGS. 1 and 2 in two-hand operation, the right-hand hand R grasping the region of the rear bend 30 like a pistol grip and the left-hand operating hand L engaging the ball region 26 of the front bend 28 from above engages, the fingers find particularly good grip in the feeder 38. In this way, a considerable working pressure can be exerted on the not shown brush tool with the left operating hand L.
  • FIG. 6 shows the same machine as FIG. 5, wherein the left operating hand L holds the region of the rear bend 30 like a pistol grip, and the right operating hand R holds the housing 12 in the region of the front bend 28 from above or laterally overlaps. In this position, a considerable working pressure on the brush tool, not shown, can be exercised ergonomically with the right-hand operating hand R.
  • FIG. 7 shows the electric brush 10 during overhead work, with the right-hand hand R grasping around the rear bend 30 like a pistol grip and the left-hand hand L embracing the front bend 28 laterally from below.
  • the left operating hand L fatigue-free high operating forces on the not shown brush tool apply.
  • FIG. 8 shows the hand tool machine in principle as handled in FIG. 7, but the thumb of the left operating hand L does not engage under the housing 12 in the region of the feeder 38, but is supported laterally on the housing shell 11 and thus has a high lateral working pressure the housing 12 and thus can apply to the brush tool not shown.
  • FIG 9 shows the handling of the power tool 10, wherein the left operating hand L engages under the housing 12 at the front bend 28 in the region of the feeder 38 and wherein the right-hand hand R, the rear bend 30 engages from above, so that the Hand tool 10 between the left and right operating hand L, R securely clamped and can be performed.
  • Figure 10 shows the hand tool 10 held in one-handed operation only in the right hand R hand, the index finger and subsequent fingers engages the housing 12 in the area of the feeder 38 at the front bend 28 and the thumb engages over the housing 12 at the top.
  • the machine 10 is also to be held securely with a single hand and suitable for compensating corresponding reaction forces of the power tool when working with the not shown brush tool.
