Definitions
- the invention relates to a protective cover for a hand tool, in particular for an electric hand tool, which has a support surface for engagement with a flange of the hand tool, and with a tensioning device for fastening the protective cover to the flange and with an anti-rotation device for fixing the angular position of the protective cover relative to the hand tool ,
- Hand tools especially electric hand tools, with rapidly rotating discs, such as angle grinders, are equipped with a protective cover to protect the user from sparks, fragments, abrasive particles and so on.
- the known protective covers are composed of a hood body and a clamping element.
- the clamping element is used for enclosing a flange of the hand tool, in particular electric hand tool, wherein the flange surrounds an axis which forms the axis of rotation of the rapidly rotating disk or the like.
- screw connections or clamping levers are used to tighten the clamping element. Clamping creates a frictional connection between the flange and the protective cover, which secures the protective cover in position and protects it from twisting.
- the support surface has at least one anti-rotation element cooperable with at least one anti-rotation counterpart element of the flange. Accordingly, the contact surface between the hood and flange, so the aforementioned support surface, at least one anti-rotation, which with a
- Anti-rotation counter element of the flange can cooperate.
- the support surface is formed on the protective hood and provided with the anti-rotation element, whereby a very simple and effective construction is present.

- the protective hood has a hood body and that the anti-rotation element is formed / arranged on the hood body.
- the protective hood lies with its hood body directly on the flange of the hand tool.
- the anti-rotation element is formed on a part of the clamping device associated with the hood body. Consequently, the anti-rotation element is not at any part of the clamping device, but just in the zone which is associated with the hood body, in particular is overlapped by the hood body.
- the anti-rotation element is designed as an embossing element and / or thermoforming element.
- the embossing requires no additional material costs. By embossing a profiling is generated, which can cooperate with a counter-profiling of Verwood Anlagenelements.
- the anti-rotation element is integrally formed on the component having it or realized as a separate component and fixed to the hood body or the clamping device.
- the support surface is preferably arcuate, in particular part-circular, formed, wherein along the arc more anti-rotation elements can be arranged.
- In the center of the mentioned pitch circle is the axis of rotation of the tool holder of the hand tool, in particular electric hand tool.
- the anti-rotation elements have a ratchet distance to each other or the multiple of a Rastrichabstandes each other. Consequently, a profiling with a uniform "pattern" over the circumference or over a partial circumference of the support surface results, so that in this peripheral zone an attachment of the protective hood is possible in corresponding, mutually offset form-fitting positions.
- Part ... indicates that the support surface is assigned to the protective cover and therefore not a full-scale size - A -
- an axial securing between protective hood and flange can be formed, wherein, as a further possibility, the support surface-seen in the axial direction-can be convex and / or concave. This can preferably also serve to form the aforementioned axial securing.
- the flange is preferably designed as an annular flange.
- Anti-rotation counter element is preferably integrally formed on the flange, wherein the flange may be preferably arcuate, in particular part-circular or circular. It is advantageous if a plurality of anti-rotation counter-elements are arranged along the mentioned arc or partial circle or the circular configuration of the flange.
- the anti-rotation counter-elements may have a Rastrichabstand or multiple of a Rastrichabstandes each other.
- the flange is cylindrical or conical, as has already been mentioned to the support surface.
- the support surface and flange are always matched to one another in a shape adapted to one another. Furthermore, it is advantageous if the anti-rotation element and the anti-rotation counterpart element interlock with each other.
- At least one guide projection is formed on the support surface or on the flange, which engages in a circumferential recess or partial circumferential recess of the flange or support surface.
- the circumferential recess or partial circumferential recess may be formed as a circumferential groove or Operathesnut.
- a tension band is preferably provided.
- the tensioning strap can be a tensioning strap which is separate from the protective cover and engages over a section of the protective cover, namely a region of the hood body, or it is a tensioning strap fastened to the hood body.
- the anti-rotation element can be arranged at the zone of the clamping band which engages over the region of the hood body.
- the tension band in one piece on the guard is trained. This is done, for example, in that the protective hood has at least one, preferably two clamping strips integrally formed with the hood body.
- the tension band can preferably be tensioned with a tension lock, which can be designed in particular as a screw connection.

- the support surface 9 forms a partial annular surface 11, wherein the circumferential angle preferably just like the other mentioned surfaces has a 180 ° extension.
- the support surface 9, that is, the entire sheet metal region which forms the support surface 9, is formed profiled, that is provided with a profiling 12.
- the cross-sectional contour of the support surface 9 does not extend semicircularly in a mathematical manner but with superimposed zig-zag structure 13, whereby tooth-like elevations 14 with intermediate recesses 15 are formed over the partial circumference.
- the elevations 14 -according to FIG. 9- have top lines 16 which extend axially; the recesses 15 have baselines 17, which likewise extend axially, ie extend in the direction of the axis of rotation 10.
- the individual elevations 14 form Verfommes demente 18, which cooperate with corresponding shape-adapted anti-rotation counter-elements of said flange of the hand tool, as will be shown in more detail below.
- the outer side 19 of the support surface 9 is overlapped by a clamping device 20 which is designed as a clamping band 21.
- the tension band 21 forms a separate part to the hood body 2, but it is fastened by suitable means to the hood body 2, in particular to the outside 19 of the support surface 9.
- the attachment is preferably by welding.
- the clamping band 21 is circular in cross-section and has a clamping closure 22 in the form of angled clamping band ends 23 and 24, wherein the clamping band end 23 has a threaded receptacle 25 and the clamping band end 24 has a through hole 26, so inserted by means of a in the through hole 26 and in the Thread receiving 25 screwed, threaded screw, not shown, the diameter of the clamping band 21 can be reduced and thereby a tension on the aforementioned flange of the hand tool, in particular the electric hand tool takes place.
- the inner side 27 of the tension band 21 is provided with a guide projection 28, which can be produced in particular by carrying out two parallel cutting cuts of the clamping band 21 consisting of sheet metal and by stretching the sheet metal area lying between the cutting cuts radially inwards.
- the embodiment of Figures 3 and 4 differs from the embodiment of Figures 1 and 2 only in that the clamping band 21 is not formed as an external clamping band, but as an inner clamping band 21, that is, the outside 29 of the clamping band 21 is located on the inside 30 of the corresponding part of the hood body 2, so that the support surface 9 is formed from the inside of the clamping band 21 in the zone which overlaps said part of the hood body 2.
- a partial circle section (FIG. 4) of the tension band 21, namely the support surface 9, is formed with a profiling 12 in a zig-zag structure 13.
- the hood body 2 is welded to the outside 29 of the tension band 21.
- the hood body 2 may also be provided with profiling, so that the two profiles of hood body 2 and clamping strap 21 engage in a form-fitting manner.
- the profiling of the support surface 9 forms at least one anti-rotation element 18th
- the embodiment of FIGS. 1 and 2 merely has the difference that the tensioning strap 21 is not formed as a separate part but as a one-piece construction with the hood body 2, that is to say with zigzagging.
- Structure 13 provided support surface 9 of the hood body 2 is integrally into two clamping strips 32 and 33, so that a total of a clamping band 21 is formed with clamping lock 22.
- the profiling 12, that is, the thus formed anti-rotation elements 18, is uniform, that is, the anti-rotation elements 18 have each other a fixed Rastrichabstand or the multiple of Rastrichabstandes.
- FIG. 8 shows the aforementioned flange 34 of the hand tool, in particular the electric hand tool, which is designed as a ring body 35 with a fastening web 36.
- a ball bearing is used to support a about the rotation axis 10 ( Figure 9) rotating shaft for receiving a tool.
- the outer side 38 of the annular body 35 of the flange 34 is provided with a counter profiling 39 for cooperation with the profiling 12 of the protective hood 1.
- the counter profiling 39 has tooth-like elevations 40 and intermediate depressions 41, wherein the elevations 40 have top lines 42 and the depressions 41 have baselines 43. Tip lines 42 and base lines 43 thus extend axially parallel to the direction of the axis of rotation 10.
- the outer side 38 of the annular body 35 is provided in the region of the counter profiling 39 with a circumferential recess 44 in the form of a circumferential groove 45. Furthermore, according to FIG. 9, the annular body 35 has on its outer side 38 a threading recess 46 for the guide projection 28 of the tensioning band 21.
- anti-rotation counter-elements 47 are formed on the flange 34, which can cooperate with the anti-rotation locking elements 18 of the protective cover 1 form-fitting and shape-matched, whereby a rotation of the protective cover 1 on the flange 34 is formed.
- the counter-profiling 39 is-just like the profiling 12- uniformly designed so that the individual anti-rotation counter-elements 47 to each other have a Rastrichabstand or the multiple of a Rastrichabstandes.
- the Rastrichabstand the Anti-rotation elements 18 corresponds to the Rastrichabstand the anti-rotation counter-elements 47 so that the guard 1 can be fixed according to the Rastrichabstand in desired angles of rotation on the flange 34 by axial plugging and subsequent tightening of the clamping device 20, as can be seen from Figures 7 and 9.
- a rotational angle position of the two parts is selected such that the guide projection 28 can enter the threading depression 46.
- the protective cover 1 is pushed completely onto the annular body 35 of the flange 34, then the guide projection 28 lies within the circumferential groove 45, so that an axial securing device is formed and a relative rotation of the protective cover 1 to the flange 34 is possible when the tensioning strap 21 is not yet tensioned. If the desired rotational position of these parts is reached, then the clamping band 21 is tensioned by appropriate closing of the clamping closure 22, so that it reduces its diameter and therefore between the guard 1 and the flange 34 both a frictional connection and a positive connection is made, the positive connection due the interlocking anti-rotation elements 18 and anti-rotation counter 47 is generated.
- the profiling 12, which is associated with the hood body 2 preferably extends only over a partial circumference; the counter-profiling 39 of the flange 34 preferably extends around the entire circumference.
- the tension band can be designed as a ring-shaped circumferential band, in particular as a smooth ring.
- the strap is not encircling, but integrally continues the guard neck (support surface 9).
- the aforementioned flange 34 of the electric hand tool forms an interface to the protective hood 1, wherein due to the profiling 12 and counter-profiling 39 in a variety of rotational position angles, the protective cover 1 on the flange 34 is non-positively and positively fastened.
- the profiling 12 and counter-profiling 39 each-as already mentioned-parallel to the axis of rotation 10 is formed.
- profile gradients for example, with a slope, similar to a thread pitch of a screw, an arrow profile, similar to an arrow toothing in transmissions, or a profile profile with variable pitch.
- the profiling and / or counter profiling can be formed over 360 ° or over only a partial circle or partial arc.
- truncated cone shapes and / or concave and / or convex contact surfaces are conceivable, for example, truncated cone shapes and / or concave and / or convex contact surfaces.
- the contact surface, in particular support surface, between protective hood 1 and flange 34 may, as already mentioned, be cylindrical or partially cylindrical and / or conical or partially conical and / or convex and / or concave.
- the anti-rotation which is formed by the at least one anti-rotation element 18 in conjunction with the at least one anti-rotation counter 47, may also be provided with profile shape, ie in terms of axial extent straight or oblique to the axis of rotation 10, arcuate or mixed forms of the mentioned profile forms, wherein at an oblique course and angular sections can be specified.
- FIG. 10 shows various support surface configurations
- FIG. 11 shows hybrid forms of support surface formations
- FIG. 12 shows profile shapes of the anti-rotation device
- FIG. 13 shows hybrid forms of profile shapes.
- the profile assigned to the guard must be able to move "ratchet-like" over the profile of the flange if the jig is not tightly clamped, but this possibility of rotation is only given if the profile of the guard 1 is only extends over an angular range which is smaller than 180 ° and therefore does not require widening of the protective hood neck or the like during rotation, rather, the protective cover moves in the direction of the arrow emerging from FIG. 14 during rotation, without resulting in elastic deformation of the protective cover 1. If the profiling assigned to the protective hood were 180 ° or about 180 °, then corresponding undercuts would occur, ie a movement in the direction of the arrow emerging from FIG.
- the protective cover 14 would not be possible without widening the protective hood 1 or its neck the protective cover 1, however, vo Preferably consists of a relatively rigid sheet material, such expansion should be avoided.
- the protective cover it is of course also possible to manufacture the protective cover from a suitably compliant material, so that an expansion can take place. Then the profiling of the guard could well have an angular range of 180 °.
- the undercuts mentioned are allowed in inflexible hoods. The consequence, however, is that when adjusting the handling is less comfortable, since then always the protective cover 1 must be deducted from the flange axially, then the new rotation angle adjustment takes place and in the new position again an axial sliding on the flange is performed. A comfortable ratchet-like adjustment can not be done.
