Description

Akku-HandwerkzeugmaschineCordless hand tool
Stand der TechnikState of the art
Die vorliegende Erfindung geht aus von einer Akku-Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1.The present invention is based on a cordless handheld power tool according to the preamble of claim 1.
Es sind schon Akku-Handwerkze g aschinen bekannt, bei denen zwischen dem Gehäuse und dem lösbaren Akku-Pack ein längli- ches Hilfswerkzeug von außen unsichtbar untergebracht ist, das nur nach Entnahme des Akku-Packs herausnehmbar ist.Cordless hand tools are already known in which an elongated auxiliary tool is invisibly accommodated from the outside between the housing and the detachable battery pack and can only be removed after the battery pack has been removed.
Das Hilfswerkzeug dient dabei zum Lösen bzw. Befestigen des Werkzeugs der Akku-Handwerkzeugmaschine, z.B. des Sägeblatts einer Handsäge . Durch die besagte Unterbringung des Hilfswerkzeugs zwischen dem Akku-Pack und dem Gehäuse ist gesichert, dass ein Sägeblattwechsel nur bei gelöstem Akku-Pack möglich ist. Dadurch ist auszuschließen, dass bei versehentlichem Berühren der Schalttaste das Sägeblatt während des Sägeblattwechsels bewegt wird und den Benutzer verletzt.The auxiliary tool is used to loosen or attach the tool of the cordless handheld power tool, e.g. of the saw blade of a hand saw. The said placement of the auxiliary tool between the battery pack and the housing ensures that a saw blade change is only possible when the battery pack is detached. This means that if the switch button is accidentally touched, the saw blade will be moved during the saw blade change and injure the user.
Da das Hilfswerkzeug zwischen Akku-Pack und Gehäuse unsichtbar versteckt ist, ist es schwerer aufzufinden. Schlimmstenfalls vergißt der Benutzer, wo das Hilfswerkzeug unterge- bracht ist und benützt ohne Abnehmen des Akkus ein anderes passendes Hilfswerkzeug mit der bereits geschilderten Verletzungsgefahr .Since the auxiliary tool is hidden between the battery pack and the housing, it is more difficult to find. In the worst case, the user forgets where the auxiliary tool is located and uses another suitable auxiliary tool with the risk of injury already described without removing the battery.
Vorteile der ErfindungAdvantages of the invention
Die Erfindung mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass das Hilfswerkzeug an exponierter Lage der Akku- Handwerkzeugmaschine gegen Verlieren gesichert aber deutlich sichtbar untergebracht ist und besonders schnell, sozusagen blind, verfügbar ist. Dadurch, dass das Hilfswerkzeug winklig ausgestaltet ist, wobei beide Enden im Gehäuse gelagert sind und ein mittlerer Bereich, insbesondere der winklige Bereich, aus dem Gehäuse herausragt, bildet das Hilfswerkzeug einen Vorsprung, der besonders gut tastbar bzw. greifbar ist.The invention with the features of claim 1 has the advantage that the auxiliary tool is secured against exposure to the exposed position of the cordless hand-held power tool, but is clearly visible and is available particularly quickly, so to speak blindly. Characterized in that the auxiliary tool is angular, both ends are mounted in the housing and a central area, in particular the angular area, protrudes from the housing, the auxiliary tool forms a projection that is particularly easy to feel or grasp.
Dadurch; dass der winklige Bereich des Hilfswerkzeugs soweit über die Außenkontur des Gehäuses heraustritt, daß er durchgreifbar ist, kann er bei hakenartigem Durchgriff des Fin- gers nach Abnahme des Akku-Packs besonders einfach entnommen werden. Außerdem bildet das Hilfswerkzeug durch diese Anordnung eine Öse, an der es aufhängbar, lagerbar bzw. transportierbar ist.Thereby; that the angled area of the auxiliary tool protrudes beyond the outer contour of the housing to such an extent that it can be gripped through, it can be removed particularly easily if the finger is passed through like a hook after the battery pack has been removed. In addition, the auxiliary tool forms an eyelet through this arrangement, on which it can be suspended, stored or transported.
Dadurch, dass die Außenkontur des Gehäuses im Bereich der heraustretenden Hilfswerkzeugs einen Einzug bildet, ist das Hilfswerkzeug zumindest von einem Finger bequem durchgreifbar und besonders einfach entnehmbar.Because the outer contour of the housing forms a draw-in in the area of the emerging auxiliary tool, the auxiliary tool can be easily gripped by at least one finger and can be removed particularly easily.
Dadurch, dass das Hilfswerkzeug zwei, insbesondere einen längeren und kürzeren Schenkel aufweist, wobei der eine Schenkel in ein durch den Akku-Pack verdecktes Loch im Gehäuse parallel zur Akku-Einschubrichtung einsteckbar ist und der andere Schenkel in eine Nut im Gehäuse benachbart zum Akku-Pack einlegbar ist, ist das Hilfswerkzeug vibrationsgeschützt aufbewahrt und die Gefahr von Klappergeräuschen beim Arbeiten mit der Akku-Handwerkzeugmaschine ausgeschlossen.Characterized in that the auxiliary tool has two, in particular a longer and shorter leg, one leg can be inserted into a hole in the housing hidden by the battery pack parallel to the battery insertion direction and the other leg into a groove in the housing adjacent to the battery Pack can be inserted, the auxiliary tool is stored in a vibration-protected manner and the risk of rattling noises when working with the cordless hand-held power tool is excluded.
Dadurch, dass das Hilfswerkzeug nur bei gelöstem Akku-Pack entnehmbar ist und durch den eingesteckten Akku-Pack unverlierbar an der Handwerkzeugmaschine verriegelt ist, kann das Hilfswerkzeug nicht bei aktivierbarem Akku-Pack entnommen werden, so dass die Sicherheit des Benutzers beim Werkzeugwechsel gewährleistet und die Verletzungsgefahr minimiert ist. ZeichnungBecause the auxiliary tool can only be removed when the battery pack is detached and is locked captively on the handheld power tool by the inserted battery pack, the auxiliary tool cannot be removed when the battery pack can be activated, so that the safety of the user when changing the tool is guaranteed and Risk of injury is minimized. drawing

Ausführungsbeispieleembodiments
Figur 1 zeigt eine Seitenansicht einer als Kreissäge ausgestalteten Handwerkzeugmaschine 10, deren Gehäuse 12 mit einem Handgriff 14 für die haltende Hand und einen Führungshandgriff 15 für die führende Hand des Benutzers.FIG. 1 shows a side view of a handheld power tool 10 designed as a circular saw, the housing 12 of which has a handle 14 for the holding hand and a guide handle 15 for the guiding hand of the user.
Der Haupthandgriff 14 trägt eine Schalttaste 16 zum Ein- undThe main handle 14 carries a switch button 16 for on and
Ausschalten des nicht dargestellten Antriebsmotors . Oberhalb der Schalttaste 16 ist ein seitlich eindrückbarer Arretierknopf 17 zum Feststellen der Schalttaste 16 im Einschaltmodus angeordnet .Switching off the drive motor, not shown. Above the switch button 16 there is a locking button 17 which can be pushed in at the side to lock the switch button 16 in the switch-on mode.
Seitlich an das Gehäuse 12 angeflanscht ist ein Sägeblattgehäuse 19, das ein Motorgehäuse 18 trägt, das sich in Betrachtungsrichtung aus der Zeichenebene heraus erstreckt.Flanged to the side of the housing 12 is a saw blade housing 19 which carries a motor housing 18 which extends out of the plane of the drawing in the viewing direction.
Unten trägt das Sägeblattgehäuse 19 eine Pendelschutzhaube 20, die schützend das nicht dargestellte Kreissägeblatt umgreift.At the bottom, the saw blade housing 19 carries a pendulum guard 20, which surrounds the circular saw blade (not shown) in a protective manner.
Das Gehäuse 12 und das Sägeblattgehäuse 19 sind mit einer Fußplatte gekoppelt und mittels eines Gelenks 24 daran höhenverstellbar und schwenkbar gelagert. Mittels einer Feststellschraube 26 ist das Gelenk 24 arretierbar, so dass beliebige Schwenkpositionen des Gehäuses 12, 18 gegenüber der Fußplatte 22 feststellbar sind.The housing 12 and the saw blade housing 19 are coupled to a base plate and are mounted thereon in a height-adjustable and pivotable manner by means of a joint 24. The joint 24 can be locked by means of a locking screw 26, so that any pivot positions of the housing 12, 18 relative to the base plate 22 can be locked.
Aus dem Gehäuse 12 tritt in Betrachtungsrichtung rechts nach unten parallel zur Erstreckung des Haupthahdgriffs 14 ein Akku-Pack 28 aus. Dieses hat seitliche Lösetasten 30, durch deren Eindrücken der Akku-Pack 28 vom Gehäuse 12 parallel zum Haupthandgriff 14 lösbar bzw. entsprechend dem Bewegungspfeil 46 abnehmbar ist. In Verlängerung des Unterrandes 32 des Gehäuses 12 erstreckt sich ein als Sechskantwinkel- Schlüssel ausgestaltetes Hilfswerkzeug 38, das winklig nach außen aus der Kontur des Gehäuses 12 herausragt und eine Durchgriffsöffnung 50 definiert.A battery pack 28 emerges from the housing 12 in the viewing direction on the right downward parallel to the extension of the main handle 14. This has side release buttons 30, by pressing the battery pack 28 from the housing 12 parallel to the main handle 14 detachable or removable according to the movement arrow 46. In the extension of the lower edge 32 of the housing 12 extends an auxiliary tool 38 designed as a hexagon wrench, which protrudes at an angle outwards from the contour of the housing 12 and defines a passage opening 50.
Das Hilfswerkzeug 38 tritt mit einem langen Schenkel 35 parallel zur Einsteckrichtung des Akku-Packs 28 in eine engge- passte, federnde Einstecköffnung 40 ins Innere des Gehäuses 12 und ist dabei mit ihrem kurzen Schenkel 37 in einer Einlegenut 42 parallel zum Unterrand des Gehäuses 12 bündig bis zum Nutgrund 44 einlegbar.The auxiliary tool 38 enters with a long leg 35 parallel to the insertion direction of the battery pack 28 into a tight, resilient insertion opening 40 into the interior of the housing 12 and is flush with its short leg 37 in an insertion groove 42 parallel to the lower edge of the housing 12 can be inserted up to groove base 44.
Figur 2 zeigt das Gehäuse 12 der Handwerkzeugmaschine 10 oh- ne Motorgehäuse 18 und ohne Sägeblattgehäuse 19 in auseinandergezogener Darstellung mit dem Akku-Pack 28 und dem Hilfswerkzeug 38.FIG. 2 shows the housing 12 of the hand power tool 10 without the motor housing 18 and without the saw blade housing 19 in an exploded view with the battery pack 28 and the auxiliary tool 38.
Dabei ist ein Kontaktzylinder 29 des Akku-Packs 28 deutlich erkennbar, mit dem der Akku-Pack 28 - entsprechend dem Bewegungspfeil 46 - tief ins Innere des Handgriffs 14 bzw. des Gehäuses 12 eingeschoben wird.Here, a contact cylinder 29 of the battery pack 28 can be clearly seen, with which the battery pack 28 is pushed deeply into the interior of the handle 14 or the housing 12, in accordance with the movement arrow 46.
Das Hilfswerkzeug 38, auch als ImbusSchlüssel bezeichnet, ist mit seinem langen Schenkel in die Einstecköffnung 40 geschoben und bis zum Anschlag des kürzeren Schenkels 37 am Nutgrund 44 einschiebbar. Erst dann kann der Akku-Pack 28 einrastbar am Gehäuse 12 befestigt werden.The auxiliary tool 38, also referred to as an Allen key, is pushed with its long leg into the insertion opening 40 and until the shorter leg 37 stops Groove base 44 can be inserted. Only then can the battery pack 28 be snapped onto the housing 12.
Das Abnehmen des Akku-Packs 28 geschieht in umgekehrter Richtung wie das Einfügen. Erst nach Abnehmen des Akku-Packs 28 vom Gehäuse 12 ist auch ein Entnehmen des Hilfswerkzeugs 38 überhaupt bzw. bequem möglich. Durch Eingreifen in die Durchgriffsöffnung 50, die von dem durch eine konkav gewölbte Gehäusekontur gebildeten Einzug 43 des Gehäuses 12 und dem winkligen Bereich des Hilfswerkzeugs 38 gebildet wird.The battery pack 28 is removed in the opposite direction to the insertion. Only after removing the battery pack 28 from the housing 12 can the auxiliary tool 38 be removed at all or conveniently. By engaging in the through opening 50, which is formed by the indentation 43 of the housing 12 formed by a concavely curved housing contour and the angular region of the auxiliary tool 38.
Das Gehäuse 12 weist seitliche Schrauböffnungen 74, 76 auf, durch das Schrauben 34, 36 steckbar sind, mit denen das Sä- geblattgehäuse 19 flanschartig seitlich an das Gehäuse 12 schraubbar ist.The housing 12 has lateral screw openings 74, 76 through which screws 34, 36 can be inserted, with which the saw blade housing 19 can be screwed laterally to the housing 12 in a flange-like manner.
Das Hilfswerkzeug 38 kann demnach nur bei entnommenem Akku- Pack 28 aus dem Gehäuse 12 genommen werden. Mit dem Hilfswerkzeug 38 kann dann eine nicht dargestellte Innensechs- kantschraube zur Befestigung des nicht mit dargestellten Sägeblatts auf der Motorwelle schraubend in Löserichtung bzw. Befestigungsrichtung gedreht werden. Damit ist gewährleistet, dass bei versehentlichem Berühren der Schalttaste 16 der Elektromotor der Akkuhandwerkzeugmaschine nicht in Bewe- gung gesetzt wird und der Benutzer dann beim Sägeblattwechsel durch dessen Rotation verletzt wird. The auxiliary tool 38 can therefore only be removed from the housing 12 when the battery pack 28 is removed. With the auxiliary tool 38, a hexagon socket screw, not shown, for fastening the saw blade, not shown, on the motor shaft can then be screwed in the loosening direction or fastening direction. This ensures that if the switch button 16 is touched inadvertently, the electric motor of the cordless handheld machine tool is not moved and the user is injured by its rotation when changing the saw blade.
