Definitions

  • the invention relates to a hand tool according to the preamble of claim 1.
  • Hand tool machines for rotating, preferably disc-shaped tools are known. They are used, for example, as angle grinders variously.
  • Protective hoods are provided in such hand tool machines which have the task of keeping the sparks and material particles being thrown away from the operator or from areas of the environment when working with the portable power tool by the rotating tool, for example grinding or cutting disks.
  • the guard should also protect the user and the environment in the event of destruction of the tool. It may happen, for example, that a cutting disc breaks in the workpiece when it is tilted there in the rotation. It must be ensured by the protective hood that fragments of the crushed cutting disc, which are thrown away with high energy sometimes, not reach the area of the operator.
  • the protective covers cover the workpiece only in segments, for example in an angular range of about 180 °, to leave the operator sufficient freedom of work on the rotating tool and workpiece.
  • it is known in the prior art to detachably secure the protective hood for example by means of a tensioning band arranged on the protective hood.
  • solutions are known in which the clamping band is expanded and reduced by loosening and tightening a clamping screw in the circumference, so that the protective hood is held by a clamping action on the machine neck.
  • an electric hand tool in which a protective hood can be fastened to the electric hand tool by means of a tension clamp in the form of a spring ring which is provided with profilings which can be introduced into recesses of the protective hood neck.
  • the published patent application DE 101 24 439 A1 an electric hand tool, in which the protective hood can be fastened by means of a clamping band provided with a profiling on a provided with a profiling flange of the power tool.
  • a disadvantage of the known from the prior art electric hand tool machines is that when loosening the guard of the housing of the electric power tool always the clamp from the electric hand tool must be solved.
  • the object of the invention is to present a further development which avoids the disadvantages mentioned and allows a high level of protection for the operator of the electric hand tool with greater comfort.
  • an electric hand tool machine for a rotating, preferably disc-shaped tool with a machine housing having a machine neck to which a protective cover for at least partially covering the tool is releasably secured, wherein the guard has a guard neck and provided for releasably securing a clamp is in each case a profiling arranged or formed on the clamping collar and on the guard neck or on the guard neck and on the machine neck or on the guard neck and on the clamp and on the machine neck to form a force acting between machine neck and guard against rotation, wherein the electric hand tool machine characterized in that the clamp is formed as a separate component and fixed to the machine housing.
  • the clamp is not formed as part of the protective hood, for example, as part of the protective hood neck, which is formed in the prior art as a rule in its diameter larger and smaller, open and a clamping device of the clamp closable ring ( about a screw or a lever).
  • the clamp is designed as a separate component that is not connected to the protective hood, but only receives the protective cover when it is attached to the electric power tool.
  • the clamp is in this case attached to the machine housing, so that the protective hood without further parts of the machine housing of the electric power tool solved and hereby also reconnected can.
  • a profiling is provided, which may be formed or arranged on the clamp and, corresponding thereto, on the guard neck, or on the guard neck and on the machine neck or on the guard neck and on the tension clamp and on the machine neck.
  • profiling is here in particular, but not only, a sequence of substantially similar elevations and depressions in cross section, for example in the form of a wavy line meant. It is provided that the profiling is formed either on the clamp and on the guard neck, with the versions of clamp and guard neck correspond, so that rotation in the engagement of the profiling is no longer possible, or on the guard neck and on the clamp, or on the machine neck and the guard neck and on the clamp, so on all three elements, not just on two of three.
  • the profiles are each designed so that they correspond to the individual elements, so allow a positive and non-positive engagement.
  • any profiling is conceivable, which is configured beyond the actual level of the outer and / or inner surface of the respective part, so not just a wave profile, but for example, a design as a knob profile with corresponding recesses on the other part et cetera.
  • the machine neck is concentric with the protective hood neck. This allows an equally spaced rotation of the guard around the machine neck.
  • the guard neck is encompassed by the clamp. Between the clamp fixed to the machine housing and the machine neck, an annular clearance is thus provided into which the guard neck is inserted and engaged. If then the clamp is applied (ie brought into engagement and tensioned), a positive and a form fit on the profiling is formed on the friction already known in the prior art, so that an absolutely secure against rotation holding the guard on the power tool is effected.
  • this construction method is also a very simple and comfortable for the user loosening the entire protective cover of the power tool possible. This is especially true when the clamp can be opened and closed via an already known in the art tensioning lever for increasing the size of the clamping collar and -creasing.
  • the machine neck and / or the guard neck has a compensating element, in particular a ring consisting of elastic material, in particular rubber, in order to compensate for tolerances between the guard neck and the machine neck.
  • a compensating element in particular a ring consisting of elastic material, in particular rubber, in order to compensate for tolerances between the guard neck and the machine neck.
  • the protective neck surrounds or partially surrounds the machine neck.
  • the guard neck may be formed here as a completely annular or only in a very small area open ring shape, so that the machine neck is substantially completely encompassed by the guard neck. But he can also only partially embrace the machine neck. All that is required is that the neck of the protective hood comes into contact with the machine neck in such a contact contact that the profiling formed on the individual components engages.
  • the guard neck is formed as a ring member or ring segment member.
  • a ring element of the guard neck annularly surrounds the machine neck, in training as a ring segment element he surrounds him only partially annular.
  • the latter variant is particularly preferable when a complete design of an annular protective disc neck for design reasons not useful, not desired or not possible.
  • the formation of the protective hood neck can only take place in the angular range which is also covered by the protective pane.
  • the clamp forms a clamping device which reduces its diameter during clamping or has such a clamping device.
  • the tensioning and thus determining the protective neck through the clamp is thus carried out by a reduction in diameter of the clamping device, which may be formed, for example, as a clamping band, which is actuated by a lever (such as a known from the prior art clamping lever or toggle). This results in a frictional engagement as well as the engagement of the profiling a form and adhesion.
  • the anti-rotation device is formed via the profiling as adjustable twisting device of the protective hood relative to the machine neck.
  • the rotation, which is formed by said profiling in this case is designed so that it allows twisting and targeted setting of the protective hood relative to the machine neck within a certain range of rotation. The operator can therefore take the protective cover from the engagement of the profiling after opening the clamp and re-insert and set in a different position relative to the machine neck in the profiling.
  • the profiling is designed either as a full circle on all profiled elements or as a circular segment or section so that a circular section over a larger Area is profiled as another, for example, on the guard trained, so that a twisting and redetermining is possible. Details show the figures.
  • the tension clamp has a tension clamp reinforcing element, which is designed in particular as a partial ring.
  • the clamping collar is therefore at least partially, for example in the form of a part of a ring, the outer circumference surrounded by a reinforcing element, which may be riveted or welded, for example, to avoid too great a change in shape of the clamp, which could lead to instability and fatigue. This ensures that the form-fitting of profiling and counter profiling is done safely and a profiling formed on the clamp is not deformed by the continuous widening and reducing the circumference of the clamp for the purpose of clamping.
  • FIG. 1 shows a protective cover 1 for a hand tool, not shown here, namely an angle grinder.
  • the protective cover 1 is configured in the manner of a pot section 2, with a protective cover bottom 3 and a protective cover edge 4.
  • the protective cover edge 4 is designed substantially as a ring section 5.
  • the one-sided adjoining protective cover bottom 3 essentially describes a semicircle 6, wherein concentric with an imaginary center of the semicircle 6 a protective hood neck 7 is formed, which has a guard wall 8, which is substantially perpendicular to the protective cover bottom 3, and the guard neck 7 in turn semicircular is formed around the imaginary center of the semicircle 6, to this consequently concentric with the same section line 9.
  • the guard neck 7 is thus formed as a ring segment element.
  • the guard neck 7 which is designed in the form of a Schutzhalshalnoteringes 12, has on its outer peripheral side 13 and on its inner catching side 14 each have a profiling 15, such that it consists of counselserhöhungen 16 and 17 of circumferential recesses. As a result, in the broadest sense, a wave profile 18 is formed.
  • the profiling 15 may be formed correspondingly on the outer peripheral side 13 and the inner circumferential side 14, for example, in that the Schutzhalshalcertainring 12 is manufactured as a molded part or as a die-cast part; Inner peripheral side 14 and outer peripheral side 13 may have different profiles.
  • the guard neck 7 is formed as a guard neck full ring 19 or as a ring member 47.
  • the full guard neck ring 19 is thus subdivided into a profiled area 20 and a non-profiled area 21. This makes it possible to restrict the angular displacement of the protective hood 1 relative to the hand tool; Consequently, the operator can not pivot the guard in a full circle, but only in a circle segment, which is predetermined by the arrangement of the profiling 15 and the counter profiling not shown here on a machine neck of the power tool.
  • FIG. 3 shows a machine neck 22 in the form of a flanged on a Getriebeabdeckplatte 23 or with this integrally formed arrangement.
  • the machine neck 22 has an outer peripheral side to the in FIG. 1 represented profiling corresponding, so in particular shape-related counter-profiling 24.
  • the protective hood 1, not shown here is slipped over the machine neck 22 with the guard neck 7, not shown here, wherein the profiling 15 located on the protective hood 1 engages in the counter-profiling 24 and in this case causes a positive and non-positive connection, in particular if further means, about a strap, to enter.
  • the machine neck 22 further has a concentric recess 25 through which a drive shaft, not shown here, is guided for driving the illustrated rotary tool.
  • the machine neck 22 further has a circumferential securing groove 26 into which a groove engaging element, for example a cam, formed on the inner circumference of the protective hood neck 7 engages via a recess also formed on the protective hood neck 7 as a groove inlet 27.
  • a groove engaging element for example a cam
  • a captive 34 is formed in cooperation with the Nuteingriffselement the guard neck 7, which prevents the accidental sliding of the guard 1 of the machine neck 22.
  • FIG. 4 shows in cross-sectional plan the assembly of the protective hood neck 7 on a machine neck 22, which is integrally formed to a Getriebeabdeckplatte 23.
  • the machine neck 22 has the counter profiling 24, which engages positively in the profiling 15 of the protective hood neck 7.
  • an anti-rotation 48 is formed.
  • the continue Groove insertion 27 as a recess on the machine neck 22 for the introduction of Nuteingriffelements 28 in the here not visible due to the perspective of the representation circumferential Sich ceremoniessnut 26.
  • the protective hood neck 7 is formed as a protective hood half 12 on the circumferential counter-profile 24 of the machine neck 22 in a full circle adjustment of Guard 1 on the machine neck relative to the machine neck 22 and the Gereteabdeckplatte 23 permits.
  • the guard neck 22 is encompassed by a clamp 29, which is designed as an open clamping ring 30.
  • the open clamping ring 30 is in this case by clamping means 31 which are shown here only symbolically and may have any known from the prior art form of clamping means, enlarged in its scope to solve the guard neck 7 from the engagement of profiling 15 and counter-profiling 24 and the Protective cover from the machine neck 22 to be able to decrease, or reduced, to press the protective hood neck 7 with the profiling 15 positively into the counter-profile 24 and beyond between the clamp 29 and the guard neck 7 and the machine neck 22 to effect a frictional connection / frictional engagement.
  • the clamp 29 has two arranged on her mounting tabs 32 which are held on the Gereteabdeckplatte 23 by means of a screw 33, which may be the screw connection of the Gereteabdeckplatte 23 with the machine housing, not shown.
  • the attachment tabs 32 serve here also as Drehrerichtstoff the clamp 29 relative to the Getriebeabdeckplatte 23.
  • the representation of the Gereteabdeckplatte 23 was only exemplary; It is also possible to form the machine neck directly on a gear housing or on another part of the housing of the power tool, provided that the necessary position relative to the rotary tool or its drive spindle, which are not shown here, is secured.
  • FIG. 5 shows in cross-sectional plan view the assembly of the protective hood neck 7, which is designed as a protective guard neck ring 19, but only a Schutzhalshalnovprofiltechnik 35, mounted on the machine neck 22 having a smooth (not profiled) Maschinenhalsau modwandung 36.
  • the guard neck 7 has a non-profiled guard neck inner side 37, but at one Guard neck outside 38 a guard neck outer profile 39.
  • the guard neck 7 is encompassed by the clamp 29, which has a Schutzschaubenhalsau touchprofil réelle 39 corresponding clamping collar profiling 40.
  • the clamping means 31 opposite is applied to the clamp 29 for shape stabilization and reinforcement of the clamp 22, a tension clamp reinforcement member 41 which formed as a partial ring 42 and fixedly connected to the clamp 29, for example, is welded.
  • the clamp 29 is further held by fastening tabs 32 on the gear cover plate 23, wherein the mounting tabs 32 are held by screw 33, which is also the fixation of Gereteabdeckplatte 23 in a machine housing 43 a hand tool 44, namely an angle grinder 45, attached.
