Definitions
- the invention relates to a hand tool according to the preamble of claim 1.
- Brushes designed as hand-held power tools with diverse, in particular rod-like, housing shapes are known which differ above all in terms of their drive and their working effect and in which handling was previously of secondary importance.
- angle grinders with a rotating tool which is arranged approximately at right angles to the housing axis and which can also be a clampable brush tool.
- Two-hand operation with high holding forces is required, such as when cleaning stubbornly soiled parts with an angle grinder or a hand drill with inserted brush tool.
- the hand-held power tool according to the invention with the characterizing features of claim 1 is much easier to handle than known hand-held power tools, in particular when operating with two hands with high operating force with a brush tool inserted, because the double-kinked arrangement of the housing ends means that they can be securely clamped in the hands of the operator. that this ensures particularly effective guiding and working in a variety of holding positions.
- the tool preferably at an angle of less than 90 °, in particular by 60 °
- a small area of the housing receiving the tool being inclined parallel or in alignment with the tool or bent relative to the elongated area and that a small area of the rear end of the housing facing away from the tool is also angled or kinked, preferably by less than 90 °, in particular by 60 °, with respect to the elongated area, is particularly easy to handle with a particularly large number of different holding positions the operator's hands are secured with both one-hand and two-hand operation.
- the bent, tool-receiving area of the housing has a waist at the kink. points, the fingers of the operating hands are given a particularly secure, defined hold.
- the housing has an at least partially spherical area in the area of the kink, the operating hands have a comfortable, large-area grip.
- a lateral indentation is arranged on the side of the spherical area, in particular on each housing shell, further improves the grip security on the housing, with the annular bead on the bent region of the housing receiving the tool near the tool holder, causing unwanted touching of the brush tool prevents the operator's hand and improves work safety.
- the hand-held power tool has a snap-on clamping device for interchangeable brush tools of different sizes and shapes ensures universal use in the case of quick brush changes.
- the clamping device can be released by means of a button, the tool change is possible quickly and easily.
- the button is formed from an area of the ring bead, it is particularly easy to reach by the operator's hand.
- the fact that the housing is made in shell construction, the bent housing at both ends is torsion and bending resistant and easier to assemble than in pot construction.
- FIG. 1 shows a side view of an electric brush with a housing angled obliquely in the longitudinal direction
- FIG. 2 shows a view from above of the electric brush according to FIG. 1
- FIGS. 3, 4 show two further exemplary embodiments of an electric brush
- FIGS. 5 to 9 show the exemplary embodiment of the electric brush according to FIG. 1 in different two-hand operating positions
- Figure 10 this electric brush in one-hand operating position.
- the handheld tool shown in longitudinal section in FIG. 1 is designed as an electric brush 10 and has a housing 12 which extends in the middle in an approximately cylindrical, elongated manner as the main housing part 12a and which is configured at both ends longitudinally at an angle of approximately 45 ° as a front and rear bend 28, 30 .
- the main housing part (12a) contains an electric motor 14 which is rotatably connected to an output shaft 18 via a gear 16.
- the output shaft 18 receives an interchangeably insertable brush tool 20 so that it can be rotatably clamped for rotational driving.
- the brush tool 20 has a shank-like insertion end, which can be locked in a rotationally fixed manner in a tensioning device of the output shaft 18, which cannot be lost.
- the transmission housing 12 In its straight middle region, the main housing part 12a, the transmission housing 12 carries on its upper side a switching slide 22 for actuating an electric switch for switching the electric motor 14 on and off.
- An electric cable emerging from the rear end 30 serves to supply power to the electric motor 14
- a setting wheel 25 of an electronic speed control is arranged at the end of the rear bend 30 of the housing 12.
- the main housing part 12a merges into the front, downward bend 28, the upper side of the housing 12 being designed as a knee-like spherical region 26 in the region of the bend 28.
- the front bend 28 merges at the bottom, at its free end close to the coupling area of the brush tool 20, into an annular bead 34.
- the annular bead 34 serves to support the operator's guiding hand and is intended to prevent the hand from slipping towards the brush tool 20.
- a segment area of the annular bead 34 is designed as a pushbutton 32 with which the clamping device (not described in more detail) can be released by pressing it down, so that the brush tool 20 can then be easily removed.
- a waist 36 is formed between the ball region 26 and the front bend 2E, which gives the handheld power tool 10 a particularly good grip.
- the housing 12 On the underside opposite the spherical region 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 top view of the exemplary embodiment according to FIG. 1, the switching slide 22 at the top of the main housing part 12a, the housing shells 11, 13 of the housing 12, the spherical region 26, the waist 36 and the waist-like indentations being particularly clear 38 ', 39, the front bend 28, the annular bead 34, the push button 32 and the rear bend 30 can be seen.
- the exemplary embodiment shown in FIG. 4 differs from the previous exemplary embodiments by a slightly longer region of the front bend 108 without a waist-like indentation and by a rear bend 110 shaped like a pistol grip.
- FIG. 5 shows the electric brush 10 according to FIGS. 1 and 2 in two-hand operation, the right control hand R encompassing the area of the rear bend 30 like a pistol grip and the left control hand L from above onto the ball area 26 of the front bend 28 engages, the fingers find particularly good hold in the feed 38.
- FIG. 6 shows the same machine as FIG. 5, the left control hand L holding the area of the rear bend 30 spanned like a pistol grip and the right control hand R holding the housing 12 in the area of the front bend 28 from above or respectively overlaps laterally. In this position, a considerable working pressure can be exerted on the brush tool (not shown) in an ergonomically favorable manner with the right operating hand R.
- FIG. 7 shows the electric brush 10 when working overhead, the right control hand R embracing the rear bend 30 like a pistol grip and the left control hand L embracing the front bend 28 laterally from below.
- the left operating hand L can apply high operating forces to the brush tool (not shown) without fatigue.
- FIG. 8 shows the hand-held power tool in principle as handled in FIG. 7, but the thumb of the left operating hand L does not reach under the housing 12 in the area of the feeder 38, but is supported laterally on the housing shell 11 and thereby has a high lateral Can apply working pressure on the housing 12 and thus on the brush tool, not shown.
- FIG 9 shows the handling of the hand tool 10, the left control hand L engages under the housing 12 at the front bend 28 in the area of the feed 38 and the right control hand R overlaps the rear bend 30 from above, so that the Hand machine tool 10 can be securely clamped and guided between the left and right operating hand L, R.
- FIG. 10 shows handheld power tool 10 held in one-hand operation only in the right operating hand R, with the pointing finger and subsequent fingers engages under housing 12 in the area of indentation 38 at front bend 28 and the thumb engages over housing 12 at the top.
- the machine 10 can also be held securely with a single hand and is suitable for compensating the corresponding reaction forces of the hand tool when working with the brush tool, not shown.
