Description

Die Erfindung betrifft ein Elektrohandwerkzeuggerät mit einem Gerätegehäuse und einem gegenüber dem Gerätegehäuse darin begrenzt beweglich gehaltenen und ein Kabel aus dem Gerätegehäuse herausführenden Kabelknickschutz, wobei der Kabelknickschutz ein Gelenkteil aus einer ersten Kunststoffkomponente und ein Tüllenteil aus einer zweiten Kunststoffkomponente aufweist.The invention relates to an electric hand tool device having a device housing and a limited relative to the device housing movably held therein and a cable out of the device housing Kabelknickschutz, the Kabelknickschutz has a hinge part of a first plastic component and a Tüllenteil of a second plastic component.

Ein derartiger Kabelknickschutz ist aus der DE 43 44 635 A1 bekannt. Das Kabel wird mittels des Kabelknickschutzes vor zu starker Biegung im Einmündungsbereich in das Gerätegehäuse geschützt, sodass das Kabel nicht durch einen Knick beschädigt werden kann. Gelenkteil und Tüllenteil sind dabei separate Einzelteile, die mittels einer Clipsverbindung miteinander verrastet werden.Such a Kabelknickschutz is from the DE 43 44 635 A1 known. The cable is made by means of the cable bend protection Too strong a bend in the junction area protected in the device housing, so that the cable can not be damaged by a kink. Joint part and Tüllenteil are separate items that are locked together by means of a clip connection.

Bei bekannten Elektrohandwerkzeuggeräten hat es sich als nachteilig herausgestellt, dass ein Lösen der Clipsverbindung zwischen Gelenkteil und Tüllenteil nicht mit Sicherheit zu vermeiden ist. Dadurch kann das Tüllenteil verrutschen, und das Kabel ist nicht mehr gegen Knicken geschützt.In known electric hand tool devices, it has proved to be disadvantageous that a release of the clip connection between the hinge part and the sleeve part can not be avoided with certainty. As a result, the tulle part can slip, and the cable is no longer protected against kinking.

Aufgabe der Erfindung ist es, ein Elektrohandwerkzeuggerät vorzuschlagen, bei dem der Kabelknickschutz verbessert ist.The object of the invention is to propose an electric hand tool device in which the Kabelknickschutz is improved.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass die zweite Kunststoffkomponente des Tüllenteils an die erste Kunststoffkomponente des Gelenkteils angespritzt ist.According to the invention this object is achieved in that the second plastic component of the Tüllenteils is molded onto the first plastic component of the joint part.

Durch das Anspritzen des Tüllenteils an das Gelenkteil sind beide so miteinander verbunden, dass sie nicht zerstörungsfrei voneinander zu trennen sind. Bei der ersten Kunststoffkomponente des Gelenkteils und bei der zweiten Kunststoffkomponente des Tüllenteils kann es sich um den gleichen Kunststoff handeln. Bevorzugt wird jedoch ein Elektrohandwerkzeuggerät, bei dem die erste Kunststoffkomponente des Gelenkteils und die zweite Kunststoffkomponente des Tüllenteils unterschiedliche Kunststoffe aufweisen. Besonders vorteilhaft ist, wenn die erste Kunststoffkomponente des Gelenkteils eine Kunststoffhartkomponente aufweist und das Tüllenteil eine Kunststoffweichkomponente. Dadurch kann ein flexibles Tüllenteil realisiert werden, so dass das Kabel im Wesentlichen ungehindert geführt ist.By injecting the Tüllenteils to the hinge part both are connected to each other so that they are not separated from each other destructively. The first plastic component of the joint part and the second plastic component of the tulle part may be the same plastic. However, preference is given to an electric hand tool device in which the first plastic component of the joint part and the second plastic component of the tulle part have different plastics. It is particularly advantageous if the first plastic component of the joint part comprises a plastic hard component and the tulle part is a plastic soft component. As a result, a flexible sleeve part can be realized, so that the cable is guided substantially unhindered.

Eine vorteilhafte Weiterbildung des erfindungsgemäßen Elektrohandwerkzeuggeräts sieht vor, dass das angespritzte Tüllenteil und das Gelenkteil einen Hinterschnitt bilden. Von besonderem Vorteil dabei ist, dass zusätzlich ein Formschluss in einer Längsrichtung (Richtung des Kabels) realisiert ist.An advantageous development of the electric hand tool device according to the invention provides that the molded-on tulle part and the joint part form an undercut. Of particular advantage is that in addition a positive connection in a longitudinal direction (direction of the cable) is realized.

Weiterhin erweist es sich als vorteilhaft, dass durch den Hinterschnitt größere Kräfte durch den Kabelknickschutz aufgenommen werden können als bei einer Anspritzung ohne Hinterschnitt.Furthermore, it proves to be advantageous that greater forces can be absorbed by the undercut through the cable bend protection than in a gating without undercut.

Bei einem bevorzugten Ausführungsbeispiel des Elektrohandwerkzeuggeräts weist das Gelenkteil eine außen verrundete Schale auf. Das Gelenkteil kann dabei in Gänze oder nur in einem Teilbereich verrundet sein.
Von besonderem Vorteil ist dabei, dass das Gelenkteil mittels der außen verrundeten Schale im Gerätegehäuse begrenzt beweglich ist, ohne dort zu verkanten.In a preferred embodiment of the electric hand tool device, the joint part has an externally rounded shell. The joint part can be rounded in whole or only in a partial area.
It is particularly advantageous that the hinge part by means of the outside rounded shell in the device housing is limited mobility without tilting there.

In Weiterbildung des vorgenannten Erfindungsgedankens ist die Innenseite der außen verrundeten Schale des Gelenkteils ebenfalls zumindest bereichsweise verrundet ausgebildet. Es folgt insbesondere einer Kugel- oder Kalottenform. Von besonderem Vorteil ist dabei, dass durch die verrundete Innenseite der Schale des Gelenkteils keine scharfen Kanten ausgebildet sind, so dass bei Belastung des Kabelknickschutzes einem Einschneiden des Gelenkteils in das Tüllenteil vorgebeugt ist. Der so gebildete Hohlraum des Gelenkteils kann dann vorteilhafterweise mittels der zweiten Kunststoffkomponente ausgespritzt werden. Hierdurch kann eine elastisch nachgiebige das Kabel schützende Einfassung von Gelenkteil und Tüllenteil aneinander erreicht werden.In a further development of the aforementioned concept of the invention, the inside of the outer rounded shell of the joint part is also rounded at least in some areas. It follows in particular a ball or dome shape. It is particularly advantageous that no sharp edges are formed by the rounded inner side of the shell of the joint part, so that when loading the Kabelknickschutzes a cutting of the joint part is prevented in the Tüllenteil. The thus formed cavity of the joint part can then be injected advantageously by means of the second plastic component. As a result, an elastically flexible cable protective enclosure of hinge part and Tüllenteil be reached together.

Bei einem weiteren Ausführungsbeispiel des Elektrohandwerkzeuggeräts ist vorgesehen, dass das Gelenkteil und das Tüllenteil in einem Zweikomponenten-Spritzgussverfahren hergestellt sind. Gelenkteil und Tüllenteil werden also mittels eines Werkzeugs hergestellt.In a further embodiment of the electric hand tool device, it is provided that the joint part and the sleeve part are produced in a two-component injection molding process. Joint part and tulle part are thus produced by means of a tool.

Besonders bevorzugt wird ein Ausführungsbeispiel des Elektrohandwerkzeuggeräts, bei dem zwischen dem Kabelknickschutz und dem Gerätegehäuse Führungsmittel angeordnet sind, so dass der Kabelknickschutz begrenzt beweglich, insbesondere begrenzt schwenkbar, im Gerätegehäuse gehalten ist. Von Vorteil ist dabei, dass das Kabel sich bezüglich seiner Längsrichtung nur wenig verwindet. Dadurch ist das Kabel weitgehend gegen Beschädigung geschützt.Particularly preferred is an embodiment of the electric hand tool device, in which guide means are arranged between the Kabelknickschutz and the device housing, so that the Kabelknickschutz limited movable, in particular limited pivoting, is held in the device housing. The advantage here is that the cable only slightly twisted with respect to its longitudinal direction. As a result, the cable is largely protected against damage.

In erfindungsgemäßer Weiterbildung zu vorgenanntem Erfindungsgedanken, sind die Führungsmittel nut- und federartig oder kulissenartig ausgebildet. Vorzugsweise ist ein erstes Führungsmittel durch einen Vorsprung, insbesondere durch einen Pin, im Gerätegehäuse und ein zweites Führungsmittel durch eine Ausnehmung, insbesondere durch eine Nut, im Gelenkteil gebildet. Die Nut kann dabei zu einer Seite hin randoffen ausgebildet sein oder in Umfangsrichtung in Gänze umschlossen in das Gelenkteil eingelassen seinIn accordance with the invention according to the aforementioned idea of the invention, the guide means are nut- and spring-like or formed like a backdrop. Preferably, a first guide means is formed by a projection, in particular by a pin, in the device housing and a second guide means by a recess, in particular by a groove in the hinge part. The groove can be designed to be open-edged towards one side or enclosed in the circumferential direction in the circumferential direction in the joint part

Ferner wird ein Ausführungsbeispiel des Elektrohandwerkzeuggeräts vorgeschlagen, bei dem die erste Kunststoffkomponente des Gelenkteils eine Hartkomponente aufweist, insbesondere PA6.Furthermore, an embodiment of the electric hand tool device is proposed in which the first plastic component of the joint part has a hard component, in particular PA6.

Darüber hinaus wird ein Ausführungsbeispiel des Elektrohandwerkzeuggeräts vorgeschlagen, bei dem die zweite Kunststoffkomponente des Tüllenteils eine Weichkomponente aufweist, insbesondere PVC oder TPM.In addition, an embodiment of the electric hand tool device is proposed, in which the second Plastic component of Tüllenteils has a soft component, in particular PVC or TPM.

Bei einer erfindungsgemäßen Weiterentwicklung des Elektrohandwerkzeuggeräts weist das Tüllenteil eine radial abstehende Zunge auf, in der eine Halterung für ein Werkzeug gebildet ist. Zur Stabilisierung kann die Zunge dabei von einem verstärkten Materialrand umgeben sein. Bevorzugt wird ein Ausführungsbeispiel der Zunge, bei dem die Halterung mittels eines vorzugsweise randbegrenzten Kreuzschlitzes gebildet ist.In a further development of the electric hand tool device according to the invention, the tulle part has a radially projecting tongue in which a holder for a tool is formed. For stabilization, the tongue may be surrounded by a reinforced edge of material. Preferred is an embodiment of the tongue, wherein the holder is formed by means of a preferably edge-limited cross slot.

Die Figuren zeigen einen Kabelknickschutz 2 mit einem Gelenkteil 4 und einem Tüllenteil 6. Das Tüllenteil 6 ist an das Gelenkteil 4 angespritzt.The figures show a Kabelknickschutz 2 with a hinge part 4 and a Tüllenteil 6. The Tüllenteil 6 is molded onto the hinge part 4.

Aus Figur 1 ist ersichtlich, dass das Gelenkteil 4 eine verrundete Kontur aufweist. Es umfasst zwei auf eine Längsrichtung projizierte Nuten 10. Die Nuten 10 sind beispielhaft in Erstreckungsrichtung auf das Tüllenteil 6 hin geschlossen und in entgegengesetzter Richtung randoffen. Das Tüllenteil 6 weist eine Zunge 12 auf, die quer zur Achse 8 radial nach außen vorsteht. Die Zunge 12 weist eine randseitige Verstärkung 14 auf. Darüber hinaus weist die Zunge 12 eine durch einen Kreuzschlitz 16 gebildete Halterung 18 auf. Die Halterung 18 ist so ausgebildet, dass ein Werkzeug einsteckbar ist und von der Halterung 18 gehalten wird.Out FIG. 1 it can be seen that the hinge part 4 has a rounded contour. It comprises two grooves 10 projected on a longitudinal direction. The grooves 10 are closed by way of example in the direction of extent on the sleeve part 6 and are open in the opposite direction. The sleeve part 6 has a tongue 12, which projects transversely to the axis 8 radially outward. The tongue 12 has a peripheral reinforcement 14. In addition, the tongue 12 has a bracket 18 formed by a cross slot 16. The holder 18 is designed such that a tool can be inserted and held by the holder 18.

Aus Figur 3 ist ersichtlich, dass die zwei Nuten 10 Führungsmittel bilden können, die diametral gegenüberliegend an dem Gelenkteil 4 ausgebildet sind. In diese Nuten können korrespondierende Führungsmittel des Gehäusekörpers eingreifen, sodass das Gelenkteil quer zur Achse der Nuten 10 schwenkbar gelagert und gegen eine Drehbewegung um die Achse 8 gehalten ist.Out FIG. 3 It can be seen that the two grooves 10 can form guide means, which are formed diametrically opposite to the joint part 4. In these grooves corresponding guide means of the housing body can engage, so that the hinge part is mounted transversely to the axis of the grooves 10 pivotally and held against rotation about the axis 8.

Die Schnittdarstellung in Figur 4 zeigt, wie das Tüllenteil 6 an das Gelenkteil 4 angespritzt ist. Das Gelenkteil 4 weist dabei im Verbindungsbereich eine sowohl außen als auch innen bereichsweise verrundete Schale 20 auf. Das Tüllenteil 6 ist so an das Gelenkteil 4 angespritzt, dass das Tüllenteil 6 und das Gelenkteil 4 in Längsrichtung 8 einen Hinterschnitt bilden und somit Tüllenteil 6 und Gelenkteil 4 nicht zerstörungsfrei voneinander lösbar sind.The sectional view in FIG. 4 shows how the tulle part 6 is molded onto the joint part 4. The joint part 4 in this case has a shell 20, which is rounded both externally and in some areas in the connection region. The tulle part 6 is molded onto the joint part 4 in such a way that the tulle part 6 and the joint part 4 form an undercut in the longitudinal direction 8 and thus the tulle part 6 and the joint part 4 can not be detached from one another without destroying each other.
