Die Erfindung geht aus von einer Handwerkzeugmaschine, insbesondere von einem Winkelschleifer, mit einem Getriebegehäuse, einem Flanschhals, mit einer auf dem Flanschhals aufnehmbaren, einen Aufnahmebereich für ein Werkzeug bildenden Schutzvorrichtung, die in Umfangsrichtung drehbar ist, und mit mindestens einer Rastvorrichtung zur Arretierung einer Drehposition der Schutzvorrichtung, wobei die Rastvorrichtung mindestens teilweise in den Flanschhals integriert ist, wobei die Rastvorrichtung mindestens eine Federeinrichtung aufweist, wobei die Rastvorrichtung mindestens ein Rastelement und mindestens eine mit dem Rastelement zusammenwirkende Rastelementaufnahme umfasst, wobei die Rastelementaufnahme an der Schutzvorrichtung ausgebildet ist, wobei das Rastelement an einem Rasthebel angeordnet ist.The invention relates to a hand tool, in particular an angle grinder, with a gear housing, a flange neck, with a recordable on the neck flange, a receiving area for a tool forming protective device which is rotatable in the circumferential direction, and at least one locking device for locking a rotational position the locking device, wherein the latching device is at least partially integrated into the flange neck, wherein the latching device comprises at least one spring device, wherein the latching device comprises at least one latching element and at least one latching element cooperating with the latching element receptacle, wherein the latching element receptacle is formed on the protective device, wherein the latching element is arranged on a latching lever.
Es wird vorgeschlagen, dass das Rastelement im unverrasteten Zustand im Flanschhals angeordnet ist und die Arretierung ausgehend vom Flanschhals zur Schutzvorrichtung hin radial erfolgt, wobei der Rasthebel um eine im Flanschhals angeordnete Achse drehbar ist. Unter "in den Flanschhals integriert" soll hierbei insbesondere innerhalb des Flanschhalses angeordnet, im Flanschhals aufgenommen, in den Flanschhals eingepasst und/oder einstückig mit dem Flanschhals ausgebildet verstanden werden. Hierdurch ist die Nutzung des bereits vorhandenen Bauraums im Getriebegehäuse bzw. im Flanschhals möglich. Zusätzlich ist ein Großteil der Bauteile der Rastvorrichtung im Getriebegehäuse bzw. im Flanschhals vor Schmutz und Beschädigung geschützt, da diese größtenteils von dem Aufnahmebund der Schutzvorrichtung umgeben werden. Ferner wird eine Arretierung gewährleistet, die ein Verdrehen der Schutzvorrichtung aus einer definierten Position von über 90° sicher verhindert. Vorteilhafterweise ist eine sehr einfache Bedienung der Rastvorrichtung ohne Werkzeug möglich. Die Arretierung ausgehend vom Flanschhals zur Schutzvorrichtung hin erfolgt radial. Hierunter soll insbesondere verstanden werden, dass die Arretierungsbewegung bzw. die Bewegung der Rastvorrichtung radial erfolgt bzw. dass die Bewegung in radialer Richtung ausgeführt wird. Vorteilhafterweise ist dadurch der Großteil der Rastvorrichtung im Flanschhals integrierbar.It is proposed that the latching element is arranged in the unlatched state in the flange neck and the locking takes place radially starting from the flange neck towards the protective device, wherein the latching lever is rotatable about an axis arranged in the flange neck. In this case, "integrated into the flange neck" is to be arranged in particular within the flange neck, received in the flange neck, fitted into the flange neck and / or understood to be formed integrally with the flange neck. As a result, the use of the existing space in the transmission housing or flange neck is possible. In addition, a large part of the components of the locking device in the gear housing or flange neck is protected from dirt and damage, since these are largely surrounded by the receiving collar of the protective device. Furthermore, a lock is ensured, which reliably prevents a rotation of the protective device from a defined position of over 90 °. Advantageously, a very simple operation of the locking device without tools is possible. The locking, starting from the flange neck towards the protective device, takes place radially. By this is to be understood in particular that the locking movement or the movement of the latching device takes place radially or that the movement is carried out in the radial direction. Advantageously, this means that the majority of the latching device can be integrated in the flange neck.
Vorteilhafterweise wirkt die Arretierung der Schutzvorrichtung zusätzlich axial. Die Schutzvorrichtung ist somit nicht nur radial, sondern auch axial gegen Verdrehen bzw. Verschieben gesichert. Hierunter soll insbesondere verstanden werden, dass die Arretierung auch in einer anderen als der axialen Richtung erfolgen kann, aber dennoch in axialer Richtung wirkt.Advantageously, the locking of the protective device additionally acts axially. The protective device is thus not only secured radially, but also axially against rotation or displacement. This is to be understood in particular that the locking can also take place in a direction other than the axial direction, but nevertheless acts in the axial direction.
Des Weiteren wird vorgeschlagen, dass die Arretierung über einen Formschluss zwischen Rastvorrichtung und Schutzvorrichtung erfolgt. Hierdurch ist eine besonders sichere Arretierung der Schutzvorrichtung auf dem Flanschhals gewährleistet. Eine sehr einfach herstellbare Realisierungsmöglichkeit des Formschlusses wird dadurch erreicht, dass die Rastvorrichtung mindestens ein Rastelement und mindestens eine mit dem Rastelement zusammenwirkende Rastelementaufnahme umfasst.Furthermore, it is proposed that the locking takes place via a positive connection between locking device and protective device. As a result, a particularly secure locking of the protective device is ensured on the flange neck. A very easy to produce feasible realization of the positive connection is achieved in that the latching device comprises at least one locking element and at least one cooperating with the locking element locking element receptacle.
Die Rastelementaufnahme ist an der Schutzvorrichtung ausgebildet, wodurch eine einfache Herstellung der Schutzvorrichtung realisierbar ist. Das Rastelement ist im unverrasteten Zustand im Flanschhals angeordnet, wodurch die Schutzvorrichtung auf dem Flanschhals gedreht und neu positioniert werden kann. Unter "angeordnet" soll insbesondere untergebracht oder aufgenommen verstanden werden.The locking element receptacle is formed on the protective device, whereby a simple production of the protective device can be realized. The locking element is arranged in the unlocked state in the flange neck, whereby the protective device can be rotated on the flange neck and repositioned. By "arranged" should be understood in particular housed or recorded.
Alternativ hierzu wird vorgeschlagen, dass mehrere Rastelemente an der Schutzvorrichtung ausgebildet sind. Hierdurch wird die Axialsicherung der Schutzvorrichtung verbessert, da diese Rastelemente umlaufend in einer Nut des Flanschhalses geführt werden und dadurch ein axiales Abrutschen der Schutzvorrichtung verhindert.Alternatively, it is proposed that a plurality of latching elements are formed on the protective device. As a result, the axial securing the protective device is improved because these locking elements are circumferentially guided in a groove of the flange neck and thereby prevents axial slipping of the protective device.
Eine sehr einfach herstellbare und platzsparende Realisierungsmöglichkeit der Rastelementaufnahme sieht vor, dass es sich hierbei um eine Ausnehmung oder eine Vertiefung handelt.A very easy to produce and space-saving realization of the locking element recording provides that this is a recess or a depression.
Dadurch, dass die Rastvorrichtung mindestens eine Federeinrichtung aufweist, wird vorteilhafterweise automatisch ein dauerhafter Formschluss zwischen Schutzvorrichtung und Rastvorrichtung erzeugt, welcher jederzeit vorzugsweise manuell und mit geringem Kraftaufwand gelöst werden kann. Dadurch, dass die Federeinrichtung die Rastvorrichtung ausgehend vom Flanschhals zur Schutzvorrichtung hin beaufschlagt, ist die Nutzung des bereits vorhandenen Bauraums im Getriebegehäuse bzw. im Flanschhals möglich. Zusätzlich ist die Federeinrichtung im Getriebegehäuse bzw. im Flanschhals vor Schmutz und Beschädigung geschützt, da diese von dem Aufnahmebund der Schutzvorrichtung umgeben wird.Characterized in that the latching device has at least one spring device, advantageously a permanent positive connection between the protective device and locking device is automatically generated, which can be solved at any time, preferably manually and with little effort. Due to the fact that the spring device acts on the latching device starting from the flange neck towards the protective device, it is possible to use the already existing installation space in the gearbox housing or in the flange neck. In addition, the spring device is protected in the gear housing or flange neck from dirt and damage, since it is surrounded by the receiving collar of the protection device.
Eine platzsparende, montage- und bedienerfreundliche Rastvorrichtung wird dadurch ermöglicht, dass das Rastelement und/oder die Rastelementaufnahme an einem Rasthebel angeordnet sind/ist. Alternativ ist es auch denkbar, dass das Rastelement und/oder die Rastelementaufnahme an einem Rastschieber angeordnet sind/ist. Hierdurch ist das Lösen des Formschlusses zwischen Schutzvorrichtung und Flanschhals aufgrund der Hebelwirkung mit sehr geringem Kraftaufwand möglich.A space-saving, easy-to-install and user-friendly locking device is made possible by the latching element and / or the latching element receptacle being / are arranged on a latching lever. Alternatively, it is also conceivable that the locking element and / or the locking element receptacle on a Locking slide are arranged / is. As a result, the release of the positive connection between the protective device and flange neck is possible due to the leverage effect with very little effort.
Des Weiteren wird vorgeschlagen, dass der Rasthebel derart ausgestaltet ist, dass die Schutzvorrichtung bündig auf dem Getriebegehäuse aufliegt, wodurch ein problemloses Verdrehen und neues Positionieren der Schutzvorrichtung auf dem Flanschhals möglich ist.Furthermore, it is proposed that the locking lever is designed such that the protective device rests flush on the transmission housing, whereby a trouble-free rotation and repositioning of the protection device on the flange neck is possible.
Dadurch, dass der Rasthebel um eine im Flanschhals angeordnete Achse drehbar ist, ist vorteilhaft die Nutzung des bereits vorhandenen Bauraums im Getriebegehäuse bzw. im Flanschhals für die Rastvorrichtung möglich.The fact that the locking lever is rotatable about an axis arranged in the flange neck, the use of the existing space in the transmission housing or in the flange neck for the locking device is advantageously possible.
Als besonders zweckmäßig hat sich erwiesen, dass das Lösen der Arretierung über ein Drücken des Rasthebels erfolgt.It has proven to be particularly expedient that the release of the locking takes place by pressing the locking lever.
Alternativ hierzu kann das Lösen der Arretierung aber auch über ein Ziehen des Rasthebels erfolgen.Alternatively, the release of the lock can also be done by pulling the locking lever.
Um eine höhere Stabilität des Winkelschleifers und insbesondere der Schutzvorrichtung zu erreichen, ist ein Stabilisierungshals vorgesehen, welcher einen Aufnahmebund der Schutzvorrichtung mindestens teilweise umgibt.In order to achieve a higher stability of the angle grinder and in particular of the protective device, a stabilizing neck is provided which at least partially surrounds a receiving collar of the protective device.
Vorteilhafterweise weist der Stabilisierungshals mindestens ein Rastelement und/oder mindestens eine Rastelementaufnahme auf. Hierdurch ist es möglich, dass das Rastelement nicht nur in die Schutzvorrichtung bzw. in den Aufnahmebund der Schutzvorrichtung, sondern auch in den Stabilisierungshals eingreift, so dass ein noch höherer Kraftfluss von der Schutzvorrichtung auf den Flanschhals bzw. das Getriebegehäuse ermöglicht ist.Advantageously, the stabilizing neck has at least one latching element and / or at least one latching element receptacle. This makes it possible that the locking element engages not only in the protection device or in the receiving collar of the protection device, but also in the stabilizing neck, so that an even higher power flow from the protection device on the flange neck or the gear housing is made possible.
Als besonders zweckmäßig hat es sich erwiesen, wenn der Stabilisierungshals eine Spannvorrichtung aufweist, da hierdurch ein eventuelles Spiel zwischen Stabilisierungshals und Schutzvorrichtung ausgleichbar ist.It has proved to be particularly expedient if the stabilizing neck has a tensioning device, as this makes it possible to compensate for any play between the stabilizing neck and the protective device.
Weitere Vorteile ergeben sich aus der folgenden Zeichnungsbeschreibung. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Die Zeichnung, die Beschreibung und die Ansprüche enthalten zahlreiche Merkmale in Kombination. Der Fachmann wird die Merkmale zweckmäßigerweise auch einzeln betrachten und zu sinnvollen weiteren Kombinationen zusammenfassen.Further advantages emerge from the following description of the drawing. In the drawing, an embodiment of the invention is shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.

Der Flanschhals 14 nimmt auf seinem Außenumfang eine Schutzvorrichtung, in Form einer Schutzhaube 20, auf. Die Schutzhaube 20 umfasst einen Grundkörper 50 und einen mit dem Grundkörper 50 verbundenen Aufnahmebund 42, welcher eine zentrale Öffnung zum freien Durchtritt der Abtriebswelle 16 bildet. Der Aufnahmebund 42 ist als zylindrischer Körper, welcher parallel zum Flanschhals 14 verläuft, ausgeführt. Der Grundkörper 50 ist zu einem Schutz eines Bedieners der Handwerkzeugmaschine vor Funken und/oder Materialpartikeln, die im Betrieb der Handwerkzeugmaschine entstehen, vorgesehen. Hierzu ist der Grundkörper 50 von einem tellerförmigen Element 52 gebildet, das eine halbkreisförmige Ausbildung aufweist, wobei das tellerförmige Element 52 einen Winkelbereich von ca. 180° des Werkzeugs 18 abdeckt. Hierdurch werden Funken und/oder etwaige Materialpartikel nach vorne, weg vom Bediener geleitet. An das tellerförmige Element 52 ist ein Schutzrand 70 angeordnet, der zunächst senkrecht zum tellerförmigen Element 52 und anschließend parallel zum tellerförmigen Element 52 ausgerichtet ist.The flange neck 14 receives on its outer periphery a protective device, in the form of a protective cover 20, on. The protective hood 20 comprises a main body 50 and a receiving collar 42 connected to the main body 50, which forms a central opening for the free passage of the output shaft 16. The receiving collar 42 is designed as a cylindrical body which runs parallel to the flange neck 14. The main body 50 is provided for protection of an operator of the power tool from sparks and / or material particles that arise during operation of the power tool. For this purpose, the base body 50 is formed by a plate-shaped element 52 which has a semicircular design, wherein the plate-shaped element 52 covers an angular range of approximately 180 ° of the tool 18. This will send sparks and / or any particles of material forward, away from the operator. To the plate-shaped element 52, a protective edge 70 is arranged, which is initially aligned perpendicular to the plate-shaped element 52 and then parallel to the plate-shaped element 52.
Die Schutzhaube 20 wird mit dem Aufnahmebund 42 auf den Flanschhals 14 aufgestülpt und soll auf dem Flanschhals 14 nur wenig Spiel aufweisen. Eventuell kann über ein hier nicht dargestelltes Ausgleichselement, wie beispielsweise ein Gummiring, das Spiel zwischen der Schutzhaube 20 und dem Flanschhals 14 wenigstens teilweise eliminiert werden. Zum Nachstellen des Durchmessers des Aufnahmebundes 42, um beispielsweise Verschleiß zu kompensieren, kann ferner der Aufnahmebund 42 der Schutzhaube 20 auch als eine Art Spannschelle ausgeführt sein, wobei das Nachstellen über das Anziehen einer Schraube erfolgt.The protective cover 20 is placed with the receiving collar 42 on the flange neck 14 and should have only little play on the flange neck 14. Possibly can be at least partially eliminated by a compensating element, not shown here, such as a rubber ring, the game between the guard 20 and the flange neck 14. To adjust the diameter of the receiving collar 42, for example, to compensate for wear, the receiving collar 42 of the protective cover 20 may also be designed as a kind of clamp, the adjustment is done by tightening a screw.
Die Schutzhaube 20 ist in Umfangsrichtung 22 auf dem Flanschhals 14 drehbar. Zur Arretierung einer Drehposition der Schutzhaube 20, d.h. zur radialen Arretierung der Schutzhaube 20 auf dem Flanschhals 14, ist gemäß
In den vorliegenden Ausführungsbeispielen gemäß
Um eine Schutzhaube axial auf einer Handwerkzeugmaschine zu sichern, ist üblicherweise eine zusätzliche Axialsicherung vorgesehen. In der Regel handelt es sich dabei um im Aufnahmebund der Schutzhaube vorgesehene Pins, die in eine umlaufende Nut 72 im Flanschhals eingreifen. Diese zusätzliche Arretierung kann aufgrund der erfindungsgemäßen Rastvorrichtung 24 entfallen. Im vorliegenden Fall wirkt die erfindungsgemäße Arretierung zusätzlich zu einer radialen Richtung 36 auch in axialer Richtung 54. Ein Fachmann kann jedoch trotzdem eine zusätzliche Axialsicherung vorsehen, wenn sie ihm sinnvoll erscheint.In order to secure a protective hood axially on a hand tool, usually an additional axial lock is provided. As a rule, these are pins provided in the receiving collar of the protective hood, which engage in a circumferential groove 72 in the flange neck. This additional lock can be omitted due to the locking device 24 according to the invention. In the present case, the locking device according to the invention acts in addition to a radial direction 36 in the axial direction 54. However, a person skilled in the art can still provide an additional axial securing, if it makes sense to him.

Um den Formschluss zu lösen und den unverrasteten Zustand zu erreichen, muss lediglich der Rasthebel 34d bis 34f gegen die Kraft der Federeinrichtung 30d bis 30f in Richtung Flanschhals 14d bis 14f gedrückt werden, damit der Bolzen 26d bis 26f außer Eingriff kommt, d.h. damit das als Bolzen ausgebildete Rastelement 26d bis 26f im Flanschhals 14d bis 14f angeordnet ist. Im unverrasteten Zustand der Rastvorrichtung 24d bis 24f kann nun die Schutzhaube 20d bis 20f auf dem Flanschhals 14d bis 14f gedreht und neu positioniert werden.In order to release the positive connection and to reach the unlocked state, only the locking

Neben der beschriebenen Position der Drehachse 38 für die Rasthebelvariante sind noch weitere, einem Fachmann als sinnvoll erscheinende Positionen der Drehachse 38 vorstellbar, welche es ermöglichen, den Bolzen außer Eingriff zu bringen. In
Es ist auch möglich, mehrere Rastschieber 32 und/oder Rasthebel 34 bei einer Handwerkzeugmaschine 10 vorzusehen, so dass beispielsweise ein Rastschieber 32 rechts und ein Rastschieber 32 links an der Handwerkzeugmaschine 10 vorgesehen sind. Beim Umgreifen der Maschine 10 von oben und dem Betätigen beider Rastschieber 32 wird die Schutzhaube 20 zum Verdrehen freigegeben. Sowohl beim Rastschieber 32 als auch beim Rasthebel 34 ist vorgesehen, dass über das Verschieben des Rastschiebers 32 oder das Drücken bzw. Ziehen des Rasthebels 34 der Formschluss zwischen Schutzhaube 20 und Rastvorrichtung 24 gelöst wird, so dass kein zusätzliches Werkzeug zum Verstellen der Schutzhaube 20 erforderlich ist. Es ist jedoch auch vorstellbar, dass beispielsweise über eine hier nicht dargestellte Schraube ein Vorschub erzeugt wird, der auf den Rastschieber 32 oder den Rasthebel 34 aufgebracht wird, wodurch dann der Bolzen 26 außer Eingriff gebracht wird.It is also possible to provide a plurality of latching slides 32 and / or latching levers 34 in a handheld power tool 10, so that, for example, a latching slide 32 on the right and a latching slide 32 on the left of the handheld power tool 10 are provided. When embracing the machine 10 from above and pressing both locking slide 32, the protective cover 20 is released for rotation. Both the locking slide 32 and the locking lever 34 is provided that on the displacement of the locking slide 32 or pressing or pulling the locking lever 34, the positive connection between the guard 20 and locking device 24 is released so that no additional tool for adjusting the guard 20 required is. However, it is also conceivable that, for example, via a screw, not shown, a feed is generated, which is applied to the locking slide 32 or the locking lever 34, whereby then the bolt 26 is disengaged.
