Description

Die Erfindung betrifft eine Hand-Werkzeugmaschine, insbesondere eine Schraub- und/oder Bohrmaschine, mit einem Gehäuse, einem Antriebsmotor und einer durch den Antriebsmotor antreibbaren Werkzeugaufnahme zur Aufnahme eines insbesondere als Bohr- oder Schraubwerkzeug ausgestalteten Werkzeugs, und mit einem an dem Gehäuse lösbar anordenbaren Haken gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a hand-held machine tool, in particular a screwdriver and / or drill, with a housing, a drive motor and a drivable by the drive motor tool holder for receiving a particular designed as a drilling or screwing tool, and with a detachably arranged on the housing Hook according to the preamble of claim 1.

Eine derartige Hand-Werkzeugmaschine geht beispielsweise aus JP 2004 255503 A hervor.Such a hand-held machine tool goes out, for example JP 2004 255503 A out.

Eine weitere Hand-Werkzeugmaschine mit einem Haken ist beispielsweise in der deutschen Patentanmeldung DE 10 2009 024 112 abgebildet. Mit Hilfe des Hakenarms, den man auch als ein Halteclip bezeichnen kann, kann ein Bediener die Hand-Werkzeugmaschine aufhängen, beispielsweise an einem Kleidungsstück, insbesondere einem Gürtel, einer Tasche oder dergleichen. Mithin ist also die Hand-Werkzeugmaschine aufgrund des Halteclips bzw. Hakens bequem handhabbar, insbesondere transportierbar.Another hand machine tool with a hook is for example in the German patent application DE 10 2009 024 112 displayed. With the help of the hook arm, which may also be referred to as a retaining clip, an operator can hang the hand-held machine tool, for example on a piece of clothing, in particular a belt, a bag or the like. Thus, therefore, the hand-held machine tool is easy to handle due to the holding clips or hook, in particular transportable.

Der Haken wird bei der bekannten Hand-Werkzeugmaschine außenseitig am Gehäuse befestigt, wofür eine spezielle Halterung notwendig ist. Wird der Haken nicht benötigt, stört die Halterung. Der Haken steht insgesamt weit vor das Gehäuse der Hand-Werkzeugmaschine, was die Gefahr erhöht, dass sich der Haken unabsichtlich beim Gebrauch der Hand-Werkzeugmaschine verhakt, diese beispielsweise auch in beengten Platzverhältnissen nicht im gewünschten Maße einsetzbar ist oder dergleichen andere, durch voluminöse Bauweisen verursachte Probleme auftreten.The hook is attached to the outside of the housing in the known hand-held machine tool, for which a special holder is necessary. If the hook is not needed, the bracket interferes. Overall, the hook is far ahead of the case of the Hand machine tool, which increases the risk that the hook inadvertently entangled when using the hand-held machine tool, this example, even in confined spaces is not used to the desired extent or the like other problems caused by voluminous designs occur.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Hand-Werkzeugmaschine bereitzustellen, die einen Haken aufweist und bequem handhabbar ist.It is therefore the object of the present invention to provide a hand-held machine tool which has a hook and is easy to handle.

Zur Lösung der Aufgabe ist eine Hand-Werkzeugmaschine gemäß der technischen Lehre des Anspruchs 1 vorgesehen.To solve the problem, a hand-held machine tool according to the technical teaching of claim 1 is provided.

Ein Grundgedanke der Erfindung ist es, dass der Hakenarm vor das Gehäuse vorsteht, ansonsten aber der Halteschenkel in eine Halteaufnahme am oder im Gehäuse der Hand-Werkzeugmaschine eingreift, was eine platzsparende Anordnung schafft. Zudem kann sich der Halteschenkel direkt am Gehäuse oder einer mit dieser fest verbundenen, die Halteaufnahme bereitstellenden Komponente abstützen, so dass der Haken einen optimalen Halt am Gehäuse der Hand-Werkzeugmaschine findet. Die mindestens eine Halteaufnahme ist vorteilhaft als eine Steckaufnahme ausgestaltet. Der Halteschenkel bildet vorteilhaft einen Steckarm oder Steckschenkel.A basic idea of the invention is that the hook arm protrudes in front of the housing, but otherwise the holding leg engages in a holding receptacle on or in the housing of the hand-held machine tool, which creates a space-saving arrangement. In addition, the holding leg can be supported directly on the housing or a fixedly connected to this, the holding support providing component, so that the hook finds an optimal grip on the housing of the hand-held machine tool. The at least one holding receptacle is advantageously configured as a plug-in receptacle. The holding leg advantageously forms a plug arm or plug leg.

Das Gehäuse der erfindungsgemäßen Hand-Werkzeugmaschine ist mehrteilig und umfasst ein erstes und zweites Gehäuseteil, die aneinander mit Befestigungsmitteln lösbar befestigbar sind. Die Befestigungsmittel umfassen beispielsweise Rastmittel, Klemmmittel, Schrauben und dergleichen. Beispielsweise ist das erste Gehäuseteil ein den Antriebsmotor aufweisendes Maschinengehäuse, während das zweite Gehäuseteil ein Energiespeichergehäuse eines Energiespeichers ist, beispielsweise eine Art Akkupack, oder umgekehrt. Eines der Gehäuseteile kann z.B. auch ein Deckel sein. Die Halteaufnahme ist im ersten Gehäuseteil angeordnet und das zweite Gehäuseteil sichert den Haken in der Halteaufnahme, fixiert ihn vorzugsweise sogar, wenn das zweite Gehäuseteil am ersten Gehäuseteil montiert ist. Somit hat also das zweite Gehäuseteil eine Sicherungs- oder Fixierfunktion. Beispielsweise bildet das zweite Gehäuseteil eine später noch erläuterte Sicherungseinrichtung.The housing of the hand-held power tool according to the invention is in several parts and comprises a first and second housing part which are releasably fastened to each other with fastening means. The fastening means include, for example, latching means, clamping means, screws and the like. For example, the first housing part is a machine housing having the drive motor, while the second housing part is an energy storage housing of an energy storage device, for example a kind of battery pack, or vice versa. One of the housing parts may for example also be a cover. The holding receptacle is arranged in the first housing part and the second housing part secures the hook in the holding receptacle, preferably even fixes it when the second housing part is mounted on the first housing part. Thus, therefore, the second housing part has a securing or fixing function. For example, the second housing part forms a later-explained safety device.

Die Halteaufnahme kann vorzugsweise im Innenraum des Gehäuses vorgesehen sein oder auch außen, gegenüber einer äußeren Gehäusefläche zurückversetzt oder völlig, z.B. in der Art einer Tasche, in die Gehäusewand integriert. Der Halteschenkel des Hakens steht gegenüber der Außenseite der Gehäusewand zweckmäßigerweise nicht oder nur unwesentlich vor. Der Halteschenkel ist vorzugsweise zumindest teilweise in der Gehäusewand aufgenommen oder auf deren Rückseite, d.h. im Innenraum des Gehäuses, untergebracht.The holding receptacle may preferably be provided in the interior of the housing or outside, recessed against an outer housing surface or completely, e.g. in the manner of a bag, integrated into the housing wall. The holding leg of the hook is expediently not or only insignificantly in front of the outside of the housing wall. The retaining leg is preferably at least partially received in the housing wall or on the rear side, i. housed in the interior of the housing.

Zwischen dem Halteschenkel und dem Hakenarm ist zweckmäßigerweise mindestens ein Zwischenabschnitt angeordnet. Der Halteschenkel, der Hakenarm und der Zwischenarmabschnitt sind zueinander winkelig. Dies ist so zu verstehen, dass beispielsweise ein gekrümmter, U-förmiger Zwischenabschnitt zwischen dem Halteschenkel und dem Hakenarm angeordnet ist. Die Winkellage kann so getroffen sein, dass beispielsweise der Halteschenkel und der Hakenarm im Wesentlichen zueinander parallel verlaufen. Durch den Zwischenabschnitt sind die beiden anderen Abschnitte, nämlich der Halteschenkel und der Hakenarm, miteinander verbunden.Between the holding leg and the hook arm expediently at least one intermediate portion is arranged. The retaining leg, the hook arm and the Zwischenarmabschnitt are at an angle to each other. This is to be understood that, for example, a curved, U-shaped intermediate portion between the holding leg and the hook arm is arranged. The angular position may be such that, for example, the holding leg and the hook arm are substantially parallel to each other. Through the intermediate portion, the two other sections, namely the holding leg and the hook arm, connected to each other.

Die einzelnen Abschnitte oder Bestandteile des Hakens sind zweckmäßigerweise einstückig. Bevorzugt wird ein Kunststoffmaterial verwendet, z.B. faserverstärkter Kunststoff, oder wie beim Ausführungsbeispiel ein Haken, der aus Metall ist.The individual sections or components of the hook are expediently in one piece. Preference is given to a plastic material used, for example, fiber-reinforced plastic, or as in the embodiment, a hook that is made of metal.

Der Hakenarm und der Halteschenkel sind zweckmäßigerweise etwa gleich lang. Damit sind optimale Hebelverhältnisse erzielbar. Es versteht sich, dass der Hakenarm auch etwas länger als der Halteschenkel sein kann, beispielsweise wenn ein Einführabschnitt, der ein Einführen des Hakens am Gegenhalt erleichtert, vor den eigentlichen klemmenden oder hakenenden Abschnitt des Hakenarmes vorsteht.The hook arm and the holding leg are suitably about the same length. This optimum leverage ratios can be achieved. It is understood that the hook arm can also be slightly longer than the holding leg, for example, when an insertion, which facilitates insertion of the hook on the counter support, protruding in front of the actual clamping or hooking portion of the hook arm.

Eine Schrägneigung eines Einführabschnitts oder des Hakenarms als Ganzes kann beispielsweise so getroffen sein, dass der Hakenarm im Sinne eines größeren Abstandes seines freien Endes als seines gehäuseseitigen Endes schräg geneigt ist - was ein Einhaken erleichtert - oder umgekehrt, was einen besseren Halt am Gegenhalt zur Folge hat.An oblique inclination of an insertion section or the hook arm as a whole may, for example, be such that the hook arm obliquely inclined in the sense of a greater distance of its free end than its housing-side end - which facilitates hooking - or vice versa, resulting in a better grip on the counter-result Has.

Bevorzugt ist es, wenn der Hakenarm relativ zu der ihm zugeordneten Gehäusewand federnd ist. Der Hakenarm weist beispielsweise eine Federspannung hin zur Gehäusewand auf.It is preferred if the hook arm is resilient relative to the associated housing wall. The hook arm has, for example, a spring tension towards the housing wall.

Ferner ist es prinzipiell möglich, einen schwenkbaren oder verschiebbaren Hakenarm vorzusehen, beispielsweise um den Hakenarm zwischen einer Gebrauchsstellung und einer Nichtgebrauchsstellung zu verstellen. Die Halteaufnahme kann z.B. Schiebelager umfassen.Furthermore, it is possible in principle to provide a pivotable or displaceable hook arm, for example, to adjust the hook arm between a position of use and a non-use position. The holding receptacle may e.g. Include sliding bearing.

Der Haken kann beispielsweise S-förmig sein, wobei freie Enden des Hakens am Halteschenkel und am Hakenarm vorgesehen sind. Zwischen dem Halteschenkel und dem Hakenarm kann also ein quer verlaufender Zwischenabschnitt vorhanden sein.The hook may for example be S-shaped, wherein free ends of the hook are provided on the holding leg and on the hook arm. Thus, a transverse intermediate section may be present between the retaining leg and the hook arm.

Bevorzugt ist es, wenn der Hakenarm und der Halteschenkel etwa parallel zueinander verlaufen. Dies kann beispielsweise bei der vorgenannten S-förmigen Ausgestaltung sein, aber auch beispielsweise bei einer im Ausführungsbeispiel noch näher beschriebenen U-förmigen Ausgestaltung des Hakens.It is preferred if the hook arm and the holding leg are approximately parallel to each other. This may be, for example, in the aforementioned S-shaped configuration, but also, for example, in a U-shaped configuration of the hook, which is described in greater detail in the exemplary embodiment.

Selbstverständlich kann der Haken auch V-förmig sein, wobei der Halteschenkel und der Hakenarm jeweils Seitenschenkel des Hakens bilden. Vorzugsweise ist der Haken in der Art einer Spange ausgestaltet, wobei der Hakenarm und der Halteschenkel jeweils Seitenschenkel der Spange bilden.Of course, the hook can also be V-shaped, with the retaining leg and the hook arm each forming side legs of the hook. Preferably, the hook is designed in the manner of a clasp, wherein the hook arm and the holding leg respectively form side legs of the clasp.

Im am Gehäuse montierten Zustand des Hakens ist eine Seitenwand des Gehäuses zwischen den Seitenschenkeln angeordnet.In the housing-mounted state of the hook, a side wall of the housing between the side legs is arranged.

Zum Halten des Hakens können beispielsweise Klemmmittel, z.B. eine Klemmschraube, eine Klemmschräge, ein Keil oder dergleichen vorgesehen sein. Auch ein Riegel kann zur Befestigung des Hakens vorteilhaft sein.For holding the hook, clamping means, e.g. a clamping screw, a clamping bevel, a wedge or the like may be provided. Also, a bolt may be advantageous for attaching the hook.

Es ist auch möglich, dass ein Riegel, der die Verriegelungsfunktion ausübt, Bestandteil eines Klemmmittels oder von Klemmmitteln bildet und in der Verriegelungsstellung den Haken, insbesondere den Halteschenkel, in seiner jeweiligen Stellung klemmt. Der Haken weist zweckmäßigerweise eine Durchstecköffnung für den Riegel auf, durch der Riegel in seiner Freigabestellung zum Entfernen der Hakenanordnung von dem Gehäuse oder zum Anbringen am Gehäuse durchsteckbar ist.It is also possible that a bolt which performs the locking function forms part of a clamping means or clamping means and in the locking position, the hook, in particular the holding leg, clamped in its respective position. The hook expediently has an insertion opening for the bolt, can be pushed through the bolt in its release position for removing the hook assembly of the housing or for attachment to the housing.

Es kann auch ausreichen, den Haken mit einer Auszugssicherung vor einem Ausziehen aus der Halteaufnahme zu sichern. Dazu wird weiter unten noch näher ausgeführt.It may also be sufficient to secure the hook with a pull-out protection before pulling out of the holding receptacle. This will be explained in more detail below.

Die Halteaufnahme hält den Halteschenkel zweckmäßigerweise formschlüssig. Die Halteaufnahme hat dazu vorzugsweise Formschlusskonturen.The holding receptacle expediently holds the holding leg in a form-fitting manner. The holding receptacle preferably has form-fitting contours.

Bevorzugt ist eine Rastanordnung zum Verrasten des Hakens mit dem Gehäuse, die einen Rastvorsprung und eine Rastaufnahme umfasst. Dabei können der Rastvorsprung an der Halteaufnahme und die Rastaufnahme am Haken, vorzugsweise dem Halteschenkel, angeordnet sein. Eine bevorzugte Ausführungsform sieht dabei vor, dass der Rastvorsprung den Haken bzw. den Halteschenkel durchdringt und in seiner Raststellung in eine Rastausnehmung an der Halteaufnahme eingreift. Somit bildet der Rastvorsprung quasi einen Riegel, der verhindert, dass der Haken aus der Halteaufnahme ausgezogen werden kann.Preference is given to a latching arrangement for latching the hook with the housing, which comprises a latching projection and a latching receptacle. In this case, the latching projection on the holding receptacle and the latching receptacle on the hook, preferably the holding leg, can be arranged. A preferred embodiment provides in this case that the latching projection penetrates the hook or the holding leg and engages in its locking position in a latching recess on the holding receptacle. Thus, the locking projection virtually forms a bolt, which prevents the hook can be pulled out of the holding receptacle.

Bevorzugt sind an dem Gehäuse mehrere Halteaufnahmen, beispielsweise an zwei aneinander entgegengesetzten Seiten vorgesehene, Halteaufnahmen vorhanden, so dass einer oder mehrere Haken an dem Gehäuse in erfindungsgemäßer weise angeordnet werden können. Diese Ausgestaltung ermöglicht es beispielsweise, den Haken wahlweise an der einen oder der anderen, entgegensetzten Seite zu verwenden. So können beispielsweise Linkshänder und Rechtshänder die Hand-Werkzeugmaschine ergonomisch an ihre Bedürfnisse anpassen.Preferably, a plurality of holding receptacles, for example, provided on two mutually opposite sides, holding receptacles are provided on the housing, so that one or more hooks can be arranged on the housing in accordance with the invention. This configuration makes it possible, for example, to use the hook optionally on one or the other, opposite side. For example, left-handed and right-handed people can ergonomically adapt the hand-held machine tool to their needs.

Der Haken kann beispielsweise durch die vorgenannte Rastanordnung, durch eine Klemmhalterung oder dergleichen am Gehäuse gesichert werden. Auch ein Gegenhalt ist möglich.The hook can be secured, for example, by the aforementioned locking arrangement, by a clamp or the like on the housing. Also a counterhold is possible.

Jedenfalls ist es bevorzugt, wenn eine Sicherungseinrichtung zur Sicherung oder Fixierung des Hakens in der Halteaufnahme vorhanden ist, die einem Ausziehen des Hakens aus der Halteaufnahme entgegen wirkt.In any case, it is preferred if a securing device for securing or fixing the hook in the holding receptacle is present, which counteracts an extraction of the hook from the holding receptacle.

Die Sicherungseinrichtung liegt beispielsweise einer Einstecköffnung der Halteaufnahme gegenüber und bildet ein einem Ausziehen des Hakens aus der Halteaufnahme entgegenwirkendes Widerlager für den Haken. Es ist auch möglich, dass mindestens ein Element der Rastanordnung in seiner den Haken in der Halteaufnahme verrastenden Rasteinstellung durch die Sicherungseinrichtung gehalten wird. Die Sicherungseinrichtung verhindert somit beispielsweise ein Lösen der Rastanordnung.The safety device, for example, faces an insertion opening of the holding receptacle and forms an abutment counteracting the hook from the holding receptacle for the hook. It is also possible for at least one element of the latching arrangement to be held by the securing device in its latching setting latching the hook in the holding receptacle. The securing device thus prevents, for example, a release of the locking arrangement.

Bevorzugt hat das Gehäuse eine Durchtrittsöffnung für den Haken. Somit kann also der Halteschenkel im Gehäuse, der Hakenarm außerhalb des Gehäuses angeordnet sein.Preferably, the housing has a passage opening for the hook. Thus, therefore, the retaining leg in the housing, the hook arm can be arranged outside of the housing.

Zwar wird die Erfindung beim nachfolgenden Ausführungsbeispiel anhand einer Schraub- und Bohrmaschine dargestellt. Sie kann aber selbstverständlich auch im Zusammenhang mit anderen mobilen Hand-Werkzeugmaschinen zur Anwendung kommen, beispielsweise bei Stichsägen, Säbelsägen, Oberfräsen und dergleichen anderen Geräten.Although the invention is illustrated in the following embodiment with reference to a screwdriver and drill. However, it can of course also be used in connection with other mobile hand-held machine tools, for example in jigsaws, saber saws, routers and the like other devices.

Die Hand-Werkzeugmaschine kann netzbetrieben oder in einer bevorzugten Variante der Erfindung akkubetrieben sein.The hand machine tool may be mains powered or battery operated in a preferred embodiment of the invention.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels erläutert. Es zeigen:

Eine Hand-Werkzeugmaschine 10 ist eine kabellose, elektrische Hand-Werkzeugmaschine. Im konkreten Ausführungsfall ist die Hand-Werkzeugmaschine eine kombinierte Schraub- und Bohrmaschine, d.h. es kann mit ihr geschraubt und gebohrt werden. Zur elektrischen Energieversorgung der Hand-Werkzeugmaschine 10 dient ein Energiespeicher 50, beispielsweise ein Akkupack, der einen kabellosen, freien Betrieb der Hand-Werkzeugmaschine 10 ermöglicht.A handheld power tool 10 is a cordless, handheld power tool. In the concrete embodiment, the hand-held power tool is a combined screwdriver and drill, i. it can be screwed and drilled with it. For the electrical power supply of the hand-held power tool 10 is an energy storage 50, for example, a battery pack that allows wireless, free operation of the hand-held power tool 10.

Die Hand-Werkzeugmaschine 10 ist quasi zweiteilig, d.h. sie besteht aus einer "Grundmaschine", sowie einem an der Grundmaschine anordenbaren zweiten Bauteil, nämlich dem Energiespeicher 50.The hand-held power tool 10 is quasi two-part, i. It consists of a "basic machine" and a second component which can be arranged on the basic machine, namely the energy store 50.

Die Grundmaschine umfasst ein Maschinengehäuse 12, in dem ein Antriebsmotor 13, beim Ausführungsbeispiel ein elektrischer Antriebsmotor, untergebracht ist. Der Antriebsmotor 13 treibt über beispielsweise ein Getriebe oder direkt eine Werkzeugaufnahme 14 an einer Vorderseite 15 des Maschinengehäuses 12 an. Der Antriebsmotor 13 wird von einer Steuerung 16 angesteuert, die über eine vorliegend in an sich bekannter Weise ausgestalteten Druck-Schalter 17 Schaltbefehle, beispielsweise eine Drehzahlvorgabe sowie Ein- und Ausschaltbefehle, erhält.The basic machine comprises a machine housing 12, in which a drive motor 13, in the embodiment, an electric drive motor, housed. The drive motor 13 drives via, for example, a gear or directly to a tool holder 14 on a front side 15 of the machine housing 12. The drive motor 13 is driven by a controller 16, the 17 receives switching commands, such as a speed specification and on and off commands via a present in a known manner pressure switch.

Der Antriebsmotor 13 ist in einem Motorabschnitt 18 des Maschinengehäuses 12 untergebracht, von dem ein Handgriffabschnitt 19 sowie ein Schutzabschnitt 20 abstehen. Der Handgriffabschnitt 19 und der Schutzabschnitt 20 wiederum sind durch einen Verbindungsabschnitt 21 an einer dem Motorabschnitt 18 gegenüberliegenden Seite miteinander verbunden. Der Verbindungsabschnitt 21 bildet sozusagen die Basis oder eine Unterseite 22 des Maschinengehäuses 12. Der Motorabschnitt 18 und der Handgriffabschnitt 19 sind zueinander winkelig, so dass insgesamt eine pistolenartige Anordnung getroffen ist. Der Schutzabschnitt 20 verläuft mit Abstand zum Handgriffabschnitt 19, vorzugsweise etwa parallel. Zwischen dem Handgriffabschnitt 19 und dem Schutzabschnitt 20 ist eine Durchgrifföffnung 23 vorgesehen. Somit kann ein Bediener den Handgriffabschnitt 19 mit einer Hand umgreifen, wobei er die Durchgrifföffnung 23 durchgreift. Zur Vorderseite 15 bildet der Schutzabschnitt 20 dabei einen Schutz für die Hand des Bedieners. Der Schalter 17 ist am Handgriffabschnitt 19 angeordnet und kann von der den Handgriffabschnitt 19 umgreifenden Hand bequem betätigt werden.The drive motor 13 is accommodated in a motor section 18 of the machine housing 12, from which a handle section 19 and a protective section 20 protrude. The handle portion 19 and the protective portion 20, in turn, are interconnected by a connecting portion 21 on a side opposite to the motor portion 18 side. The connecting portion 21 forms, so to speak, the base or a lower side 22 of the machine housing 12. The motor portion 18 and the handle portion 19 are angled relative to each other, so that a total of a gun-like arrangement is made. The protective portion 20 extends at a distance from the handle portion 19, preferably approximately parallel. Between the handle portion 19 and the protective portion 20 a passage opening 23 is provided. Thus, an operator can grasp the handle portion 19 with one hand, wherein he passes through the passage opening 23. To the front 15 of the protective portion 20 forms a protection for the hand of the operator. The switch 17 is disposed on the handle portion 19 and can be conveniently operated by the hand grip portion 19 embracing hand.

Die Werkzeugaufnahme 14 ist vorliegend zum direkten einstecken eines Schrauberbits geeignet. Jedenfalls hat sie an ihrer Vorderseite eine Mehrkant-Aufnahme 24. An der Werkzeugaufnahme 14 können aber auch andere Vorsatzgeräte angebracht werden, beispielsweise ein Bohrfutter 25.The tool holder 14 is in this case suitable for direct insertion of a screwdriver bit. In any case, it has at its front a polygonal receptacle 24. On the tool holder 14 but also other attachments can be attached, such as a drill chuck 25th

An der Unterseite 22 des Maschinengehäuses 12 ist ein Montagebereich 26 für den Energiespeicher 50 vorgesehen. Das Maschinengehäuse 12 ist an seiner Unterseite 22 offen, d.h. dass der Energiespeicher 50 sozusagen einen Deckel für das Maschinengehäuse 12 bilden kann. Jedenfalls greifen nachfolgend im Detail beschriebene Komponenten in einen Innenraum 27 des Maschinengehäuses 12 zumindest teilweise ein, was in mancherlei Hinsicht, was nachfolgend noch deutlich wird, vorteilhaft ist.At the bottom 22 of the machine housing 12, a mounting portion 26 is provided for the energy storage 50. The machine housing 12 is open on its underside 22, that is to say that the energy store 50 can, as it were, form a cover for the machine housing 12. In any case, components described below in detail engage in an interior space 27 of the machine housing 12 at least partially, which results in many Regard, which is still clear below, is advantageous.

In einem Energiespeichergehäuse 51 des Energiespeichers 50 sind mehrere Speicherelemente 52 vor Umwelteinflüssen geschützt untergebracht, beispielsweise Akku-Zellen. Das Energiespeichergehäuse 51 umfasst eine Energiespeichergehäuse-Basis 53, von der ein Steckarm 54 absteht. An dem Maschinengehäuse 12 ist eine Steckarmaufnahme 28 vorgesehen, in die der Steckarm 54 eingreifen kann, wenn der Energiespeicher 50 am Maschinengehäuse 12 montiert ist. Vorteilhaft ist dabei vorgesehen, dass die Steckarmaufnahme 28 im Schutzabschnitt 20 vorgesehen ist, so dass dieser in optimaler Weise genutzt wird. Der Energiespeicher 50, d.h. dessen Energiespeichergehäuse 51, sind so ausgestaltet, dass der Energiespeicher 50 zum Maschinengehäuse 12 passt, d.h. dass der Steckarm 54 an derjenigen Seite des Energiespeichergehäuses 51 vorgesehen ist, die dem Handgriffabschnitt 19 gegenüberliegt.In an energy storage housing 51 of the energy storage 50, a plurality of storage elements 52 are housed protected from environmental influences, such as battery cells. The energy storage housing 51 comprises an energy storage housing base 53, from which an insertion arm 54 protrudes. On the machine housing 12, a plug-in arm receptacle 28 is provided, into which the plug-in arm 54 can engage when the energy store 50 is mounted on the machine housing 12. It is advantageously provided that the plug-in arm receptacle 28 is provided in the protective section 20, so that it is used in an optimal manner. The energy storage 50, i. its energy storage housing 51, are designed so that the energy storage 50 fits the machine housing 12, i. that the plug-in arm 54 is provided on the side of the energy storage housing 51, which is opposite to the handle portion 19.

Der Steckarm 54 hat eine rohrartige Gestalt und weist eine Umfangswand 55 sowie an seiner freien Seite eine Stirnwand 56 auf. Die Umfangswand 55 und die Stirnwand 56 sind zweckmäßigerweise so gestaltet, dass sie den Bauraum, den die Steckarmaufnahme 28 bietet, optimal nutzt. Beispielsweise kann der Steckarm 54 wie beim Ausführungsbeispiel eine im Wesentlichen quadratische, abgerundete Eckbereiche aufweisende Umfangskontur haben, wobei auch andere, beispielsweise flachere und/oder runde Geometrien ohne weiteres denkbar sind.The plug-in arm 54 has a tubular shape and has a circumferential wall 55 and an end wall 56 on its free side. The peripheral wall 55 and the end wall 56 are suitably designed so that they optimally uses the space that the Steckarmaufnahme 28 offers. For example, the plug-in arm 54 as in the embodiment have a substantially square, rounded corner regions having peripheral contour, with other, for example, flatter and / or round geometries are readily conceivable.

Der Steckarm 54 steht von einer Oberseite 57 des Energiespeichergehäuses 51 ab. Die Neigung des Steckarms 54 orientiert sich zweckmäßigerweise an einem Schrägverlauf des Schutzabschnitts 20 relativ zum Verbindungsabschnitt 21, so dass beispielsweise ein Winkel 69 zwischen einerseits einer Oberwand 58 des Energiespeichergehäuses 51 und andererseits dem Steckarm 54 größer 90 Grad, mithin also stumpfwinkelig ist.The plug-in arm 54 projects from an upper side 57 of the energy storage housing 51. The inclination of the plug-in arm 54 is expediently oriented on a skewed course of the protective section 20 relative to the connecting section 21, so that, for example, an angle 69 between on the one hand a top wall 58 of the energy storage housing 51 and on the other hand, the plug-in arm 54 is greater than 90 degrees, that is, therefore obtuse.

Im Steckarm 54 befinden sich beispielsweise zwei der Speicherelemente 52. Die anderen Speicherelemente 52 sind in der Basis 53 untergebracht. Die Basis 53 umfasst neben der Oberwand 58 einen Bodenwand 59 sowie zwischen diesen Wänden verlaufende Seitenwände 60, eine Rückwand 61 und eine Vorderwand 62. Die Wände 60-62 bilden insgesamt eine Umfangswand.For example, two of the memory elements 52 are located in the plug-in arm 54. The other memory elements 52 are accommodated in the base 53. The base 53 comprises, in addition to the top wall 58, a bottom wall 59 and sidewalls 60 extending between these walls, a back wall 61 and a front wall 62. The walls 60-62 form a peripheral wall as a whole.

Ferner kann in dem Steckarm 54 auch eine elektrische Schaltung 83, z.B. eine Überwachungsschaltung und/oder eine Ladesteuerung für die Speicherelemente 52, angeordnet sein.Further, in the plug-in arm 54, an electrical circuit 83, e.g. a monitoring circuit and / or a charging control for the memory elements 52 may be arranged.

Die Speicherelemente 52 sind vollständig durch das Energiespeichergehäuse 51 gekapselt. Die vorgenannten Wände oder Wandabschnitte werden beispielsweise von zwei zueinander komplementären Gehäuseteilen 63a, 63b bereitgestellt, die einstückig und integral jeweils einen Teilbereich bzw. ein Seitenteil des Steckarms 54 und der Basis 53 bilden. Die Gehäuseteile 63a, 63b sind beispielsweise miteinander verschraubt und/oder verrastet und/oder verklebt.The storage elements 52 are completely encapsulated by the energy storage housing 51. The aforementioned walls or wall sections are provided, for example, by two mutually complementary housing parts 63a, 63b, which in one piece and integrally form in each case a partial area or a side part of the plug-in arm 54 and the base 53. The housing parts 63a, 63b are, for example screwed together and / or locked and / or glued.

Im Bereich des Handgriffabschnittes 19 sind Maschinen-Anschlusskontakte 29 zum elektrischen Anschluss des Energiespeichers 50 vorgesehen. Die Maschinen-Anschlusskontakte 29 sind vorteilhaft Steckkontakte, ebenso wie mit diesen zusammenwirkende, am Energiespeicher 50 vorhandene Energiespeicher-Anschlusskontakte 64. Die Energiespeicher-Anschlusskontakte 64 und der Steckarm 54 sind aneinander entgegengesetzten Längsenden, nämliche nahe bei der Rückwand 61 bzw. der Vorderwand 63, des Energiespeichergehäuses 51 angeordnet. Somit können also die Anschlusskontakte 64 ebenso wie der Steckarm 54 eine Befestigungsfunktion erfüllen, sind also Bestandteile von Befestigungsmitteln 11, mit denen der Energiespeicher 50 am Maschinengehäuse 12, mithin also dem Grundgerät der Hand-Werkzeugmaschine 10, befestigbar ist.In the area of the handle section 19, machine connection contacts 29 are provided for the electrical connection of the energy store 50. The machine connection contacts 29 are advantageously plug contacts, as well as interacting with these, on the energy storage 50 energy storage connection contacts 64. The energy storage terminal contacts 64 and the plug 54 are mutually opposite longitudinal ends, nämliche close to the rear wall 61 and the front wall 63, the energy storage housing 51 is arranged. Thus, therefore, the terminal contacts 64 as well as the plug-in arm 54 fulfill a fastening function, so are Components of fastening means 11, with which the energy storage 50 on the machine housing 12, thus the basic unit of the hand-held power tool 10, can be fastened.

Die Montage bzw. Demontage geht dabei sehr einfach und bequem von statten, da die Befestigungsmittel 11 insgesamt einfach handhabbar sind, dennoch aber, auch unter vorteilhafter Mitwirkung des Steckarms 54 sowie der Steckarmaufnahme 28, einen sicheren Halt des Energiespeichers 50 am Maschinengehäuse 12 ermöglichen.The assembly and disassembly is very simple and comfortable of equip, since the fasteners 11 are easy to handle overall, but still, even with the beneficial participation of the plug arm 54 and the Steckarmaufnahme 28, a secure hold of the energy storage 50 on the machine housing 12 allow.

Das Energiespeichergehäuse 51 ist am Maschinengehäuse 12 formschlüssig aufgenommen. Somit sind Belastungen von Rastmitteln gering, die zweckmäßigerweise eine erste Raste 65 und eine zweite Raste 66, die mit Rastkonturen 30 und 31 zusammenwirken, umfassen.The energy storage housing 51 is received positively on the machine housing 12. Thus, loads of locking means are low, which expediently include a first catch 65 and a second catch 66, which cooperate with latching contours 30 and 31.

Beispielsweise greift der Steckarm 54 formschlüssig in die Steckarmaufnahme 28 ein. Vor einer Umfangswand 32 des Schutzabschnitts 20, der insgesamt rohrartig ist, stehen Stützvorsprünge 33 nach innen ab, an denen sich die Umfangswand 55 des Steckarms 54 abstützen kann.For example, the plug-in arm 54 engages positively in the plug-in arm receptacle 28. In front of a peripheral wall 32 of the protective portion 20, which is a total tube-like support projections 33 are inwardly from where the peripheral wall 55 of the plug-in arm 54 can be supported.

An dieser Stelle sei allerdings bemerkt, dass es durchaus im Rahmen der Erfindung liegt, wenn ein Steckarm und eine Steckarmaufnahme mit Spiel ineinander passen, d.h. ein Formschluss zwischen Steckarm und Steckarmaufnahme ist zwar vorteilhaft, jedoch nicht zwingend notwendig.It should be noted, however, that it is well within the scope of the invention, when a plug arm and a Steckarmaufnahme match with each other game, i. a form fit between the plug and Steckarmaufnahme is advantageous, but not essential.

Das Einstecken des Steckarms 54 in die Steckarmaufnahme 28 wird durch eine Steckführung oder Linearführung erleichtert. Diese umfasst z.B. eine oder zwei Führungsaufnahmen 67 an der Umfangswand 55 des Steckarms 54 sowie in die Führungsaufnahme(n) 67 eingreifende Führungsvorsprünge 34 an der Steckarmaufnahme 28. Die Führungsaufnahmen 67 sind beispielsweise als Längsnuten ausgestaltet, die in Längserstreckungsrichtung des Steckarms 54 verlaufen. Es versteht sich, dass anders als beim Ausführungsbeispiel auch eine oder mehr als zwei Führungsaufnahmen 67 vorgesehen sein können.The insertion of the plug-in arm 54 in the plug-in arm receptacle 28 is facilitated by a plug-in guide or linear guide. This includes, for example, one or two guide receptacles 67 on the peripheral wall 55 of the plug-in arm 54 and in the guide receptacle (s) 67 engaging guide projections 34 on the Steckarmaufnahme 28. The guide receptacles 67 are configured for example as longitudinal grooves which extend in the longitudinal direction of extension of the plug-in arm 54. It is understood that unlike the embodiment, one or more than two guide seats 67 may be provided.

Neben dem Steckarm 54 sind auch weitere formschlüssige Verbindungen zwischen dem Energiespeicher 50 und dem Maschinengehäuse 12 vorgesehen, beispielsweise durch ein Kontaktgehäuse 68 der Energiespeicher-Anschlusskontakte 64. Das Kontaktgehäuse 68 weist eine dem Steckarm 54 entsprechende Schrägneigung auf, also im selben Winkel 69 zur Oberwand 58 oder Oberseite 57 geneigt wie der Steckarm 54.In addition to the plug-in arm 54, other form-fitting connections between the energy store 50 and the machine housing 12 are provided, for example, by a contact housing 68 of the energy storage connection contacts 64. The contact housing 68 has an oblique inclination corresponding to the plug-in arm 54, ie at the same angle 69 to the top wall 58 or top 57 inclined as the plug 54.

Somit wird also das Energiespeichergehäuse 51 entlang einer zur Bodenwand 59 bzw. Unterseite 22 schräg verlaufenden Achse 70 an das Maschinengehäuse 12 angesteckt, wobei der Steckarm 54 in die Steckarmaufnahme 28 eingreift und zugleich auch das Kontaktgehäuse 68 in eine dieses formschlüssig aufnehmende Kontaktgehäuseaufnahme 35. Das Energiespeichergehäuse 51 ist bereits durch diese Maßnahmen quer zur Achse 70 formschlüssig im Maschinengehäuse 12 aufgenommen.Thus, therefore, the energy storage housing 51 is infected along an inclined to the bottom wall 59 and bottom 22 axis 70 to the machine housing 12, wherein the plug arm 54 engages in the Steckarmaufnahme 28 and at the same time the contact housing 68 in a form-fitting receiving contact housing receptacle 35th Das Energiespeichergehäuse 51 is already received by these measures transverse to the axis 70 positively in the machine housing 12.

Weiterhin ist die Oberseite 57 des Energiespeichergehäuses 51 als ein Steckvorsprung 71 ausgestaltet, insbesondere die Oberwand 58 als Steckvorsprung 71 ausgebildet, der in eine Steckaufnahme 36 des Maschinengehäuses 12 passt. Beispielsweise ist zwischen der Oberwand 58 und der Seitenwand 60, zweckmäßigerweise auch der Rückwand 61 der Basis 53 eine Nut 72 oder ein Rücksprung ausgebildet, in den ein freier Stirnbereich einer Umfangswand 37 des Maschinengehäuses 12, beispielsweise des Verbindungsabschnittes 21, passt. Damit greift sozusagen der Steckvorsprung 71 in einen Innenraum 27 des Maschinengehäuses 12 ein und befindet sich nach der Steckmontage innerhalb der Umfangswand 37.Furthermore, the upper side 57 of the energy storage housing 51 is configured as a plug-in projection 71, in particular the upper wall 58 is designed as a plug-in projection 71, which fits into a plug-in receptacle 36 of the machine housing 12. For example, a groove 72 or a recess is formed between the top wall 58 and the side wall 60, expediently also the rear wall 61 of the base 53, in which a free end region of a peripheral wall 37 of the machine housing 12, for example, the connecting portion 21, fits. Thus engages the plug projection 71 into an interior 27, so to speak of the machine housing 12 and is located after the plug-in mounting within the peripheral wall 37th

Zweckmäßigerweise sind die Geometrien so getroffen, dass die Umfangswand 37 und die Seitenwände 60 sowie die Rückwand 61 miteinander fluchten, wenn der Energiespeicher 50 an dem Maschinengehäuse 12 befestigt ist, so dass sich eine kontinuierliche, nahezu übergangslose Außenkontur eines (Gesamt-)Gehäuses 38 ergibt. Das Gehäuse 38 wird insgesamt durch das Maschinengehäuse 12 und das Energiespeichergehäuse 51 gebildet.Appropriately, the geometries are such that the peripheral wall 37 and the side walls 60 and the rear wall 61 are aligned when the energy storage 50 is fixed to the machine housing 12, so that there is a continuous, almost seamless outer contour of a (total) housing 38 , The housing 38 is formed entirely by the machine housing 12 and the energy storage housing 51.

Die erste Raste 65 ist in einem Übergangsbereich des Steckarmes 54 zur Basis 53 angeordnet, vorliegend an der vorderen, freien Seite des Energiespeichergehäuses 51. Mithin befindet sich die erste Raste 65 oberhalb der Vorderwand 62. Die zweite Raste 66 ist nahe bei dem Kontaktgehäuse 68 vorgesehen, also in einem deutlichen Abstand zur ersten Raste 65, so dass an weit voneinander beabstandeten Stellen eine Verrastung des Energiespeichers 50 mit dem Maschinengehäuse 12 möglich ist.The first catch 65 is arranged in a transition region of the plug arm 54 to the base 53, in this case on the front, free side of the energy storage housing 51. Thus, the first catch 65 is above the front wall 62. The second catch 66 is provided close to the contact housing 68 , So at a significant distance from the first catch 65, so that at widely spaced locations latching of the energy storage device 50 with the machine housing 12 is possible.

Vorzugsweise ist vorgesehen, dass die Raste 66 in einem Rastengehäuse 73 angeordnet ist, das ebenfalls zum formschlüssigen Halt des Energiespeichergehäuses 51 an dem Maschinengehäuse 12 beitragen kann. Beispielsweise ist eine Rückwand des Rastengehäuses 73 mit dem Winkel 69 schräg geneigt.It is preferably provided that the detent 66 is arranged in a detent housing 73, which can also contribute to the positive-locking retention of the energy storage housing 51 on the machine housing 12. For example, a rear wall of the catch housing 73 is inclined at an angle 69.

Die Rasten 65, 66 sind durch ein gemeinsames Betätigungselement 74 simultan betätigbar. Ein Bediener muss also lediglich auf das Betätigungselement 74 einwirken, um die Rasten 65, 66 außer Eingriff mit den Rastkonturen 30, 31 zu bringen. Zu diesen ist noch anzumerken, dass die Rastkontur 30 in der Nähe des Schutzabschnitts 20 durch eine von der Umfangswand des Maschinengehäuses 12 nach innen vorspringenden Abschnitt 39 gebildet ist. Die Rastkontur 31 ist an einem Querverbinder 40 angeordnet, der sich zwischen einander gegenüberliegenden Abschnitten der Umfangswand 37 erstreckt.The detents 65, 66 are actuated by a common actuator 74 simultaneously. An operator therefore only has to act on the actuating element 74 in order to bring the notches 65, 66 out of engagement with the latching contours 30, 31. It should also be noted that the locking contour 30 in the vicinity of the protective portion 20 by a projecting from the peripheral wall of the machine housing 12 inwardly portion 39th is formed. The latching contour 31 is disposed on a cross connector 40 which extends between opposed portions of the peripheral wall 37.

Jedenfalls sind die Rasten 65, 66 durch eine schematisch dargestellte Kopplungseinrichtung 76 miteinander mechanisch verbunden, die durch das Betätigungselement 74 betätigbar ist. Die Rasten 65, 66 sind in ihre Raststellung federbelastet, beispielsweise durch eine schematisch dargestellte, auf die Kopplungseinrichtung 76 einwirkende Feder 77.In any case, the detents 65, 66 are mechanically connected to each other by a schematically illustrated coupling device 76, which is actuated by the actuating element 74. The detents 65, 66 are spring loaded in their detent position, for example by a schematically illustrated, acting on the coupling device 76 spring 77th

Das Betätigungselement 74 trägt zu einem sicheren Stand der Hand-Werkzeugmaschine 10 bei, wenn sie auf einem Untergrund abgestellt wird. Das Betätigungselement 74 bildet einen Bestandteil eines Stützvorsprungs 78, der nach vorn vor die Vorderwand 62 vorsteht. Der Stützvorsprung 78 umfasst vor die Wand 62 vorstehende Wände 79, zwischen denen das Betätigungselement 74 angeordnet ist. Dessen vordere Wand 80 dient zur Druckbetätigung und ist relativ großflächig, so dass sie bequem von einem Bediener gedrückt werden kann. Die untere Wand 81 des Betätigungselements 74 hingegen vergrößert die Stützfläche, die an sich schon durch die Bodenwand 59 der Energiespeichergehäuse-Basis 53 bereit gestellt wird. Insbesondere dann, wenn an der Werkzeugaufnahme 14 ein schweres Werkzeug oder schwerer Vorsatz angeordnet ist, die Hand-Werkzeugmaschine 10 also kopflastig ist, wirkt der Stützvorsprung 78 einem Kippen der Hand-Werkzeugmaschine 10 nach vorn, d.h. zur Vorderseite 15 hin, entgegen.The actuator 74 contributes to a secure footing of the hand machine tool 10 when it is parked on a ground. The actuator 74 forms part of a support projection 78 which projects forwardly in front of the front wall 62. The support projection 78 comprises projecting walls 79 in front of the wall 62, between which the actuating element 74 is arranged. Its front wall 80 is used for printing operation and is relatively large, so that it can be easily pressed by an operator. The lower wall 81 of the actuating element 74, however, increases the support surface, which is already provided by the bottom wall 59 of the energy storage housing base 53 in itself. In particular, if a heavy tool or heavy attachment is arranged on the tool holder 14, the hand-held machine tool 10 is thus top-heavy, the support projection 78 acts to tilt the hand-held machine tool 10 forward, i. towards the front 15 towards, contrary.

Die Rasten 65, 66 sind in der Art von Rasthaken oder Rastnasen ausgebildet. Die Rasten 65, 66 verhaken sich also mit den Rastkonturen 30, 31, so dass das Energiespeichergehäuse 51 gegenüber einem Ausziehen aus dem Maschinengehäuse 12 in Richtung der Achse 70 gesichert ist. Die Rastkonturen 30, 31 sind vorteilhaft auch hakenförmig.The detents 65, 66 are formed in the manner of latching hooks or latching noses. The notches 65, 66 thus engage with the latching contours 30, 31, so that the energy storage housing 51 against being pulled out of the machine housing 12 in Direction of the axis 70 is secured. The latching contours 30, 31 are advantageously also hook-shaped.

An einem oberen, der Werkzeugaufnahme 14 zugewandten Bereich des Schutzabschnitts 20 ist noch eine Beleuchtung 41 vorgesehen, die in Richtung der Werkzeugaufnahme 14 Licht abstrahlt. Ferner ist vorteilhaft am Gehäuse 38 eine Werkzeughalterung 42 vorgesehen, beim Ausführungsbeispiel an der Vorderseite 15 des Maschinengehäuses 12. In der Werkzeughalterung 42 können beispielsweise Schrauberbits bei Nichtgebrauch gespeichert werden.At an upper, the tool holder 14 facing portion of the protective portion 20 is still a lighting 41 is provided which emits light in the direction of the tool holder 14. Further, a tool holder 42 is advantageously provided on the housing 38, in the embodiment on the front side 15 of the machine housing 12. In the tool holder 42, for example, screwdriver bits can be stored when not in use.

Die Hand-Werkzeugmaschine 10 mit dem Energiespeicher 50 ist nicht nur äußerst kompakt, sondern kann auch bequem mitgeführt werden. Hierzu ist ein Haken 100 vorgesehen, der am Gehäuse 38 lösbar befestigbar ist. Der Haken 100 weist einen Hakenarm 101 sowie einen Halteschenkel 102 auf, die zwar prinzipiell direkt miteinander verbunden sein könnten, vorliegend jedoch über einen Zwischenabschnitt 103.The hand-held power tool 10 with the energy storage 50 is not only extremely compact, but can also be easily carried. For this purpose, a hook 100 is provided, which is releasably attachable to the housing 38. The hook 100 has a hook arm 101 and a holding leg 102, which, although in principle could be connected directly to one another, but in the present case via an intermediate section 103.

Der Hakenarm 101 ist mit einem Abstand 104 zur Gehäusewand 43 beabstandet, während sich der Halteschenkel 102 an der Innenseite der Gehäusewand 43 an derselben abstützt.The hook arm 101 is spaced at a distance 104 to the housing wall 43, while the holding leg 102 is supported on the inside of the housing wall 43 at the same.

Der Haken 100 ist vorteilhaft als eine Art Spange bzw. spangenartig ausgestaltet.The hook 100 is advantageously designed as a kind of clasp or clasp-like.

Der Haken 100 hat eine in Seitenansicht U-förmige Gestalt. Zweckmäßigerweise sind der Hakenarm 101 und der Halteschenkel 102 im Wesentlichen gleich lang, so dass die Hebelverhältnisse optimal sind. Jedenfalls kann die Hand-Werkzeugmaschine 10 mittels des Hakens 100 an einem Gegenhalt, beispielsweise der Kleidung des Bedieners verhakt werden, beispielsweise um die Hand-Werkzeugmaschine 10 bequem mitzuführen oder bei insbesondere kurzfristigem Nichtgebrauch sozusagen aufhängen zu können, ohne dass der Bediener die Maschine auf einem Untergrund ablegen muss.The hook 100 has a U-shaped side view. Conveniently, the hook arm 101 and the retaining leg 102 are substantially the same length, so that the lever ratios are optimal. In any case, the hand-held power tool 10 can be hooked by means of the hook 100 on a counter-stop, for example, the clothing of the operator, for example, to carry the hand-held machine tool 10 comfortably or in particular to be able to hang it up, so to speak, without requiring the operator to place the machine on a surface.

Der Haken 100 kann an einander entgegengesetzten Seiten der Hand-Werkzeugmaschine bzw. deren Gehäuse 38 angeordnet werden, so dass beispielsweise ein bequemer Gebrauch für einen Linkshänder oder auch für einen Rechtshänder ohne weiteres realisierbar ist. Zu diesem Zweck sind im Bereich der Gehäusewand 43 vorzugsweise als Steckaufnahmen ausgestaltete Halteaufnahmen 105 vorgesehen, von denen der Haken 100 mit seinem Halteschenkel 102 wahlweise gehalten wird. Der Haken 100 ist mit seinem Halteschenkel 102 in die Halteaufnahmen 105 einsteckbar.The hook 100 can be arranged on opposite sides of the hand-held power tool or its housing 38, so that, for example, a convenient use for a left-hander or for a right-handed person is readily feasible. For this purpose, holding receptacles 105 are preferably provided in the region of the housing wall 43 as plug receptacles, of which the hook 100 is held with its holding leg 102 selectively. The hook 100 can be inserted with its holding leg 102 into the holding receptacles 105.

Vorzugsweise ist der Haken 100 im Bereich des Schutzabschnittes 20 angeordnet, so dass er den Bediener beim Ergreifen der Hand-Werkzeugmaschine am Handgriffabschnitt 19 nicht stört.Preferably, the hook 100 is arranged in the region of the protective portion 20, so that it does not disturb the operator when grasping the hand-held machine tool on the handle portion 19.

Die Halteaufnahmen 105 sind zweckmäßigerweise so getroffen, dass zumindest der Hakenarm 101, vorteilhaft auch der Halteschenkel 102, etwa parallel zu einer Mittelachse des Schutzabschnittes 20 verlaufen, die vorliegend auch der Achse 70 entspricht. Somit bildet also die Gehäusewand 43 zweckmäßigerweise auf der jeweils gesamten Länge des Halteschenkels 102 und des Hakenarms 101 ein mit dem Halteschenkel 102 bzw. Hakenarm 101 zusammenwirkendes Widerlager.The retaining seats 105 are expediently made such that at least the hook arm 101, advantageously also the retaining leg 102, run approximately parallel to a central axis of the protective section 20, which in the present case also corresponds to the axis 70. Thus, the housing wall 43 thus expediently forms an abutment cooperating with the holding leg 102 or hook arm 101 on the respective entire length of the holding leg 102 and the hook arm 101.

Der Halteschenkel 102 stützt sich zweckmäßigerweise unmittelbar an der Gehäusewand 43, d.h. an deren Innenseite, ab.The holding leg 102 is expediently supported directly on the housing wall 43, i. on the inside, off.

Die Halteaufnahmen 105 weisen zweckmäßigerweise Führungen 106 auf, die beispielsweise in der Art von Führungsnuten ausgestaltet sind. Der Halteschenkel 102 liegt an der Bodenfläche der Führung 106 im Wesentlichen flächig an, so dass er sich über seine gesamte Länge an der Gehäusewand 43 innenseitig abstützen kann.The holding receptacles 105 expediently have guides 106, which are designed, for example, in the manner of guide grooves. The retaining leg 102 is located on the bottom surface the guide 106 substantially flat, so that it can be supported on the inside of the housing wall 43 over its entire length.

Zweckmäßigerweise ist vorgesehen, dass die Halteaufnahme 105 den Haken 100, insbesondere dessen Halteschenkel 102, im Wesentlichen formschlüssig aufnimmt. Der Halteschenkel 102 wird in der Führung 106 zweckmäßigerweise durch einen oder mehrere, dem Boden 107 der Führung 106 gegenüberliegende Niederhalter, z.B. Querverbinder 108, gehalten. Ein Abstand zwischen dem Niederhalter oder Querverbinder 108 und dem Boden 107 entspricht dabei zweckmäßigerweise etwa einer Dicke des Halteschenkels 102, so dass dieser formschlüssig in den Zwischenraum zwischen Querverbinder 108 und Boden 107 einsteckbar ist.Appropriately, it is provided that the holding receptacle 105 receives the hook 100, in particular its holding leg 102, substantially form-fitting manner. The holding leg 102 is expediently held in the guide 106 by one or more hold-downs, for example, opposite the bottom 107 of the guide 106, e.g. Cross connector 108, held. A distance between the hold-down or cross-connector 108 and the bottom 107 expediently corresponds approximately to a thickness of the retaining leg 102 so that it can be inserted in a form-fitting manner into the space between the transverse connector 108 and the bottom 107.

An dieser Stelle sei bemerkt, dass der Begriff "Halteaufnahme" nicht implizieren soll, dass der erfindungsgemäß am Gehäuse einer Hand-Werkzeugmaschine 10 zu montierende Haken 100 spielfrei am Gehäuse gehalten werden muss, sondern durchaus auch ein gewisses Spiel haben kann, was in manchen Anwendungsfällen auch beispielsweise das Öffnen des jeweiligen Hakens 100 erleichtern kann.It should be noted at this point that the term "holding receptacle" should not imply that the invention according to the invention on the housing of a hand-held power tool 10 to be mounted hook 100 must be kept free of play on the housing, but may well have a certain play, resulting in some applications Also, for example, can facilitate the opening of the respective hook 100.

Der Haken 100 ist am Gehäuse 38 mittels einer Rastanordnung 109 verrastbar. Die Rastanordnung 109 umfasst Rastvorsprünge 110, die in ihre Raststellung federbelastet sind und in Rastaufnahmen 111 an dem Haken 100, konkret am Halteschenkel 102, einrasten.The hook 100 can be latched to the housing 38 by means of a latching arrangement 109. The latching arrangement 109 comprises latching projections 110, which are spring-loaded in their latching position and engage in latching receptacles 111 on the hook 100, specifically on the holding leg 102.

Die Rastvorsprünge 110 sind zweckmäßigerweise domartig. Ein Durchmesser eines jeweiligen Rastvorsprungs ist erfindungsgemäß zweckmäßigerweise so bemessen, dass ein Rastvorsprung mit seinem Außenumfang formschlüssig in die zugeordnete Rastaufnahme eingreift.The latching projections 110 are expediently dome-like. A diameter of a respective latching projection is suitably dimensioned according to the invention so that a latching projection with its outer circumference positively engages in the associated locking receptacle.

Die Rastaufnahme 111 ist als ein Durchgangsloch am Halteschenkel 102 ausgestaltet, so dass der zugeordnete Rastvorsprung 110 die Rastaufnahme 111 durchdringen kann. Der jeweilige Rastvorsprung 110 kann dann in eine der Rastaufnahme 111 gegenüberliegende Rastausnehmung 48 eingreifen, die an der Innenseite der Gehäusewand 43 vorgesehen ist. Der jeweilige Rastvorsprung 110 bildet also eine Art Riegel, der die Rastaufnahme 111 entsprechen, die somit also einer Riegelausnehmung entspricht.The latching receptacle 111 is designed as a through hole on the retaining leg 102, so that the associated latching projection 110 can penetrate the latching receptacle 111. The respective latching projection 110 can then engage in a latching recess 111 opposite the latching recess 48, which is provided on the inside of the housing wall 43. The respective latching projection 110 thus forms a kind of latch, which correspond to the latching receptacle 111, which thus corresponds to a latching recess.

Die den beiden Halteaufnahmen 105 jeweils zugeordneten Rastvorsprünge 110 sind bezüglich des Maschinengehäuses 12 ortsfest. Die Rastvorsprünge 110 sind an einem Einleger 44 angeordnet, der sich im Innenraum 27 des Maschinengehäuses 12 befindet. Der Einleger 44 umfasst eine Wand 45, die im Wesentlichen formschlüssig an der Umfangswand des Schutzabschnittes 20 innenseitig anliegt. Es versteht sich, dass anstelle eines Einlegers, der die Rastausnehmungen ausbildet, auch eine einstückige Bauweise möglich ist, d.h. dass beispielsweise federnde Rastvorsprünge im Gussverfahren an das jeweilige Maschinengehäuse direkt anspritzbar sind. Ferner ist auch die kinematische Umkehr möglich, d.h. dass beispielsweise am Haken 100 Rastvorsprünge 110 angeordnet sind, die in zugehörige Ausnehmungen am den Haken 100 aufnehmenden Gehäuse (Maschinengehäuse oder beispielsweise auch Energiespeichergehäuse) rastend eingreifen.The two holding receptacles 105 respectively associated latching projections 110 are fixed relative to the machine housing 12. The latching projections 110 are arranged on an insert 44, which is located in the interior 27 of the machine housing 12. The insert 44 comprises a wall 45, which rests substantially in a form-fitting manner on the peripheral wall of the protective section 20 on the inside. It is understood that instead of an insert, which forms the recesses, a one-piece construction is possible, i. that, for example, resilient latching projections in the casting process to the respective machine housing are directly injectable. Furthermore, the kinematic reversal is possible, i. that, for example, 100 latching projections 110 are arranged on the hook, which engage in corresponding recesses on the housing 100 receiving the hook 100 (machine housing or, for example, energy storage housing) latching.

Beim Ausführungsbeispiel sind jedoch die Rastvorsprünge 110 an der der Gehäusewand 43 zugewandten Seite der Federschenkel 46 angeordnet, wobei sie der Rastausnehmung 48 gegenüberliegen. Der Einleger 44 ist beispielsweise in das Maschinengehäuse 12 eingerastet, eingeklebt oder dergleichen. Zweckmäßigerweise sind zu einem optimalen Halt des Einlegers 44 Klemmschenkel 47 vorgesehen, die sich an der Gehäusewand 43 oder an einer sonstigen Stelle des Maschinengehäuses 12 abstützen, so dass der Einleger 44 im Klemmsitz im Maschinengehäuse 12 aufgenommen ist. An dieser Stelle ist noch nachzutragen, dass die Wand 45 an ihrer Innenseite, d.h. an der dem der Steckarmaufnahme 28 zugewandten Seite, vorteilhaft eine Führungsfunktion und/oder eine Stützfunktion für den Steckarm 54 des Energiespeichers 50 erfüllt.In the embodiment, however, the latching projections 110 are arranged on the housing wall 43 facing side of the spring legs 46, wherein they are opposite to the latching recess 48. The insert 44 is for example in the machine housing 12 engaged, glued or the like. Conveniently, 44 clamping legs 47 are provided for optimum support of the insert, which are supported on the housing wall 43 or at another point of the machine housing 12, so that the insert 44 is received in the press fit in the machine housing 12. At this point, it should also be added that the wall 45 on its inside, that is to say on the side facing the plug arm receptacle 28, advantageously fulfills a guide function and / or a support function for the plug arm 54 of the energy store 50.

Durch den formschlüssigen Halt des Hakens 100 in der jeweiligen Halteaufnahme 105 sowie zudem noch die Rastanordnung 109 ist bereits ein optimaler Halt des Hakens 100 am Gehäuse 38 möglich. Zudem kann die Position des Hakens 100 leicht geändert werden, indem er aus der einen Halteaufnahme 105 herausgezogen wird und in die andere Halteaufnahme 105 eingesteckt wird, so dass er beispielsweise die in Fig. 3 gestrichelt eingezeichnete Position einnimmt.Due to the positive locking of the hook 100 in the respective holding receptacle 105 and, in addition, the latching arrangement 109, an optimal hold of the hook 100 on the housing 38 is already possible. In addition, the position of the hook 100 can be easily changed by being pulled out of the one holding receptacle 105 and plugged into the other holding receptacle 105, so that it can, for example, the in Fig. 3 dashed line occupies position.

Auch beim Gebrauch ist der Haken 100 sehr komfortabel, da von dem Hakenarm 101 eine Einführschräge 112 nach schräg außen absteht bzw. das freie Ende des Hakenarms 101 als Einführschräge ausgestaltet ist, dergestalt, dass der jeweilige Gegenhalt in den Abstand 104 zwischen dem Hakenarm 101 und dem Gehäuse 38 hinein geführt wird. Mithin ist also die Einführschräge 112 im Sinne eines Öffnens von der Gehäusewand 43 schräg weg geneigt.Also, in use, the hook 100 is very comfortable because of the hook arm 101 an insertion bevel 112 projects obliquely outward or the free end of the hook arm 101 is designed as an insertion, such that the respective counter-stop in the distance 104 between the hook 101 and the housing 38 is guided into it. Thus, therefore, the insertion bevel 112 inclined obliquely away in the sense of opening of the housing wall 43.

Das Energiespeichergehäuse 51 bildet eine Sicherungseinrichtung 113 zur Sicherung, vorliegend sogar zur Fixierung, des Hakens 100 in der Halteaufnahme 105. Wenn das Energiespeichergehäuse 51 am Maschinengehäuse 12 befestigt ist, kann der Haken 100 nicht von dem so gebildeten Gesamt-Gehäuse 38 entfernt werden.The energy storage housing 51 forms a securing device 113 for securing, in this case even for fixing, the hook 100 in the holding receptacle 105. If the energy storage housing 51 is fixed to the machine housing 12, the Hooks 100 are not removed from the overall housing 38 thus formed.

Am Maschinengehäuse 12, an der Einsteckseite der jeweiligen Halteaufnahme 105, ist jeweils eine Durchtrittsöffnung 114 für den Haken 100 vorgesehen. Wenn der Haken 100 am Gehäuse 38 montiert ist, durchdringt er die Durchtrittsöffnung 114 mit seinen Zwischenabschnitt 103. Direkt unterhalb der Halteaufnahme 105 befindet sich - wenn das Energiespeichergehäuse 51 am Maschinengehäuse 12 befestigt ist - ein Stützabschnitt 82 des Energiespeichergehäuses 51, der somit ein Widerlager für den Haken 100 bildet. Der Haken 100 stützt sich mit seinem Zwischenabschnitt 103 am Stützabschnitt 82 ab, wobei der Stützabschnitt 82 quer zur Achse des Hakens 100 an der jeweiligen Halteaufnahme 105 verläuft. Somit kann also der Haken 100 nicht mehr aus der Halteaufnahme 105 herausgezogen werden, wenn der Energiespeicher 50 am Maschinengehäuse 12 montiert ist. Der Stützabschnitt 82 stützt den Haken 100 formschlüssig, wobei die Anordnung zweckmäßigerweise so getroffen ist, dass der Haken 100 mit sehr geringem Spiel in der Halteaufnahme 105 gehalten wird.On the machine housing 12, on the insertion side of the respective holding receptacle 105, a passage opening 114 for the hook 100 is provided in each case. When the hook 100 is mounted on the housing 38, it penetrates the passage opening 114 with its intermediate portion 103. Directly below the holding receptacle 105 is - when the energy storage housing 51 is fixed to the machine housing 12 - a support portion 82 of the energy storage housing 51, thus providing an abutment for forms the hook 100. The hook 100 is supported with its intermediate portion 103 on the support portion 82, wherein the support portion 82 extends transversely to the axis of the hook 100 on the respective holding receptacle 105. Thus, therefore, the hook 100 can not be pulled out of the holding receptacle 105 when the energy storage device 50 is mounted on the machine housing 12. The support portion 82 supports the hook 100 positively, the arrangement is suitably made so that the hook 100 is held with very little play in the holding receptacle 105.

Eine zusätzliche Sicherungsmaßnahme kann vorsehen, dass der Steckarm 54 des Energiespeichers 50 die Rastvorsprünge 110 in Richtung ihrer Raststellung belastet, beispielsweise dass die Federschenkel 46 an der Umfangswand 55 des Steckarms 54 anliegen oder anschlagen, so dass die Rastanordnung 109 nicht aus ihrem Rasteingriff gelangen kann, wenn der Energiespeicher 50 am Maschinengehäuse 12 befestigt ist.An additional safety measure may provide that the plug-in arm 54 of the energy store 50 loads the latching projections 110 in the direction of their latching position, for example, that the spring legs 46 abut or abut the peripheral wall 55 of the plug-in arm 54, so that the latching arrangement 109 can not come out of its latching engagement, when the energy storage 50 is fixed to the machine housing 12.

In Abwandlung des realisierten Ausführungsbeispiels ist es auch möglich, dass ein erfindungsgemäßer Haken 100 oder auch ein Haken 100b beispielsweise am Energiespeichergehäuse 51 befestigbar ist, d.h. dass dieses eine Halteaufnahme aufweist, beispielsweise eine schematisch in Fig. 3 eingezeichnete Halteaufnahme 105b, in die der Haken 100b mit einem Halteschenkel 102b eingreift. Der Haken 100b hat beispielsweise in Seitenansicht eine S-förmige Gestalt. Auch beim Haken 100b ist es zweckmäßigerweise so, dass er nur dann vom Gehäuse 38 entfernt werden kann, wenn das Energiespeichergehäuse 51 vom Maschinengehäuse 12 entfernt ist.In a modification of the realized embodiment, it is also possible that a hook 100 according to the invention or a hook 100b can be fastened, for example, to the energy storage housing 51, ie that it has a holding receptacle, for example, a schematic in Fig. 3 drawn holding receptacle 105b, in which the hook 100b engages with a retaining leg 102b. For example, the hook 100b has an S-shape in side view. Even with the hook 100 b, it is expedient that it can only be removed from the housing 38 when the energy storage housing 51 is removed from the machine housing 12.
