Description

Die Erfindung betrifft einen Zangendosenöffner entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a plier can opener according to the preamble of claim 1.

Bei bekannten Dosenöffnern dieser Art ist der Drehgriff in dem einen Arm gelagert und er trägt entweder das Vorschubrad und ein Zahnrad, das beim Schließen der Zange mit einem in dem anderen Arm gelagerten, mit dem als Schneidrad ausgebildeten Messer verbundenen Zahnrad in Eingriff kommt, oder er trägt das Schneidrad und ein Zahnrad, das beim Schließen der Zange mit einem in dem anderen Arm gelagerten, mit dem Vorschubrad verbundenen Zahnrad in Eingriff kommt. Derartige Zangendosenöffner sind in der Herstellung relativ teuer, da die Anbringung und Lagerung der Einzelteile an bzw. in den Armen einen verhältnismäßig großen Aufwand erfordert. Auch ist eine Beschädigung der meist aus Blech bestehenden, verchromten Arme beim Zusammenbau nicht auszuschließen.In known can openers of this type, the rotary handle is mounted in one arm and it either carries the feed wheel and a gear which, when the pliers are closed, comes into engagement with a gear mounted in the other arm and connected to the knife designed as a cutting wheel, or it carries the cutting wheel and a gearwheel which, when the pliers are closed, comes into engagement with a gearwheel mounted in the other arm and connected to the feed wheel. Plier can openers of this type are relatively expensive to produce, since the attachment and storage of the individual parts on or in the arms requires a relatively large outlay. Damage to the chrome-plated arms, which are usually made of sheet metal, cannot be ruled out during assembly.

Aufgabe der Erfindung ist es, einen Zangendosenöffner der gattungsgemäßen Art zu schaffen, der sich durch einen einfachen Aufbau und insbesondere durch einen wesentlich vereinfachten Zusammenbau seiner Bestandteile auszeichnet.The object of the invention is to provide a plier can opener of the generic type which is distinguished by a simple structure and in particular by a considerably simplified assembly of its components.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die drehbaren Bestandteile des Dosenöffners zu Einheiten zusammengefaßt sind, die auf die Arme des Dosenöffners aufgesteckt sind. Dabei ist je nach der Bauart des Dosenöffners zumindest der Drehgriff mit den mit ihm verbundenen Teilen, nämlich dem Schneidrad und einem Zahnrad oder dem Vorschubrad und einem Zahnrad in bzw. auf einem Elementeträger angeordnet ist, der auf einen der Arme aufgesteckt ist, während das Gegenelement, also im ersten Fall das Vorschubrad mit einem Zahnrad und im zweiten Fall das Schneidrad mit einem Zahnrad, auf den anderen Arm aufgesteckt ist. Vorzugsweise ist auch dieses Gegenelement an einem Elementeträger angebracht, der auf den anderen Arm aufgesteckt ist. Diese Elementeträger werden komplett vormontiert und auf die Arme aufgesteckt, so daß sich die bisher erforderliche Anbringung einer Lagerstelle für die Welle den Drehgriffes am einen Arm und einer Lagerstelle für die Welle der auf dem anderen Arm angeordneten Bauteile sowie die Halterung dieser Teile in den Lagerstellen erübrigt.This object is achieved in that the rotatable components of the can opener are combined into units which are attached to the arms of the can opener. Depending on the design of the can opener, at least the twist grip with the parts connected to it, namely the cutting wheel and a gear wheel or the feed wheel and a gear wheel is arranged in or on an element carrier which is attached to one of the arms, while the counter element, that is to say in the first case the feed wheel with a gear wheel and in the second case the cutting wheel with a gear wheel the other arm is attached. This counter element is preferably also attached to an element carrier which is attached to the other arm. These element carriers are completely pre-assembled and attached to the arms, so that the previously required attachment of a bearing point for the shaft, the rotary handle on one arm and a bearing point for the shaft of the components arranged on the other arm and the mounting of these parts in the bearing points are unnecessary .

An dem das Vorschubrad tragenden Arm ist in aller Regel ein Abstandshalter angebracht, der beim Gebrauch des Dosenöffners an der Umfangswand der Dose anliegt und für die richtige Schrägstellung der Dose zum Schneidrad sorgt. Dieser Abstandshalter kann dann ebenfalls Bestandteil des betreffenden, das Vorschubrad tragenden Elementeträgers sein.A spacer is generally attached to the arm carrying the feed wheel, which, when the can opener is in use, lies against the peripheral wall of the can and ensures the correct inclination of the can to the cutting wheel. This spacer can then also be part of the relevant element carrier carrying the feed wheel.

Es besteht auch die Möglichkeit, den Drehgriff zusammen mit dem Vorschubrad und dem vorzugsweise als Schneidrad ausgebildeten Messer auf einem Elementeträger anzuordnen, der auf einen der Arme aufgesteckt ist. In diesem Fall trägt der andere Arm nur ein Stützelement für den Dosenrand, das dem Vorschubrad gegenüberliegt. Ist dieser andere Arm wie üblich ein Blechteil, so können das Stützelement und der Abstandshalter von aus der Ebene des Blechteils hochgebogenen Lappen gebildet werden.It is also possible to arrange the rotary handle together with the feed wheel and the knife, which is preferably in the form of a cutting wheel, on an element carrier which is attached to one of the arms. In this case, the other arm carries only one support element for the edge of the can, which is opposite the feed wheel. If this other arm is a sheet metal part as usual, you can the support element and the spacer are formed by tabs bent up from the plane of the sheet metal part.

Vorzugsweise ist jeder einen Elementeträger aufnehmende Arm von einem Blechteil gebildet, das einen Ausschnitt aufweist, während der Elementeträger mit einem Einschnitt versehen ist, dessen Breite der Dicke des Blechteils und dessen Kern der Breite des Auschnittes entspricht. Der Elementeträger wird also einfach in den Ausschnitt eingesteckt und dort kraftschlüssig gehalten. Vorzugsweise sind die Ausschnitte an den einander zugekehrten Innenkanten der Arme vorgesehen, so daß die Elementeträger beim Schließen der Zange nicht aus den Ausschnitten herausgedrückt werden können.Each arm receiving an element carrier is preferably formed by a sheet metal part which has a cutout, while the element carrier is provided with an incision, the width of which corresponds to the thickness of the sheet metal part and the core of which corresponds to the width of the cutout. The element carrier is simply inserted into the cutout and held there non-positively. The cutouts are preferably provided on the mutually facing inner edges of the arms, so that the element carriers cannot be pressed out of the cutouts when the pliers are closed.

Um den Dosendeckel möglichst nahe entlang der Randwulst abtrennen zu können, ist das Schneidrad in der Regel schräg zur Ebene des Dosendeckels angeordnet. Bei dem erfindungsgemäßen Vorschlag kann dies auf einfache Weise dadurch erreicht werden, daß der Einschnitt in dem Elementeträger, der das Schneidrad aufnimmt, entsprechend schräg zu dessen Drehachse verläuft. Beim Einstecken dieses Elementeträgers in den Ausschnitt des Armes ergibt sich so die gewünschte Schrägstellung des Schneidmessers.In order to be able to separate the can lid as close as possible along the edge bead, the cutting wheel is generally arranged obliquely to the level of the can lid. In the proposal according to the invention, this can be achieved in a simple manner in that the incision in the element carrier, which receives the cutting wheel, runs correspondingly obliquely to its axis of rotation. When this element carrier is inserted into the cutout of the arm, the desired inclined position of the cutting knife is obtained.

In Fig. 1 ist ein Zangendosenöffner dargestellt, der zwei mit Griffen versehene Arme 1 und 2 aufweist, die durch einen Drehzapfen 3 schwenkbar miteinander verbunden sind. Der erste Arm 1 trägt einen Drehgriff 4 mit einem Schneidrad 5 und einem Zahnrad 6. Der zweite Arm 2 trägt ein Vorschubrad 7 und ein mit diesem verbundenes Zahnrad 8 sowie einen Abstandshalter 9.In Fig. 1, a pliers can opener is shown, which has two arms 1 and 2 provided with handles, which are pivotally connected to each other by a pivot 3. The first arm 1 carries a rotary handle 4 with a cutting wheel 5 and a gear wheel 6. The second arm 2 carries a feed wheel 7 and a gear wheel 8 connected to it, as well as a spacer 9.

Der Dosenöffner arbeitet in üblicher Weise wie folgt:
Beim Zusammendrücken der Arme gelangt das Schneidrad 5 hinter die Umfangswulst am Deckel der zu öffnenden Dose und dringt in den Deckel ein, während das Vorschubrad 7 von unten an die Umfangswulst angedrückt wird und die Zahnräder 6 und 8 miteinander in Eingriff kommen. Durch Drehen des Drehgriffes 4 wird das Vorschubrad 7 über die Zahnräder 6,8 angetrieben und und es dreht seinerseits die Dose. Der Abstandshalter 9 dient dazu, ein Schleifen des Vorschubrades 7 am Außenumfang der Dose zu vermeiden und die richtige Lage des Scheidrades zu der Umfangswulst sicherzustellen.The can opener works in the usual way as follows:
When the arms are pressed together, the cutting wheel 5 passes behind the circumferential bead on the lid of the can to be opened and penetrates into the lid, while the feed wheel 7 is pressed against the circumferential bead from below and the gears 6 and 8 come into engagement with one another. By turning the rotary handle 4, the feed wheel 7 is driven via the gears 6, 8 and, in turn, it rotates the can. The spacer 9 serves to avoid grinding of the feed wheel 7 on the outer circumference of the can and to ensure the correct position of the cutting wheel in relation to the peripheral bead.

Der Drehgriff 4 weist eine Welle 10 auf, die sich durch einen Elementeträger 11 erstreckt und an ihrem freien Ende das Schneidrad 5 und das Zahnrad 6 trägt. Zur Befestigung des Elementeträgers 11 am Arm 1 ist der Arm 1 mit einem Ausschnitt 12 (Fig. 4) und der Elementeträger 11 an seiner Umfangsfläche mit einem Einschnitt 13 (Fig. 5) versehen. Die Breite des Einschnittes 13 entspricht der Dicke des von einem Blechteil gebildeten Armes 1 und sein Kern der Breite des Ausschnittes 12. Der Elementeträger 11 wird mit seinem Einschnitt 13 in den Ausschnitt 12 eingesteckt und kraftschlüssig gehalten. Der Einschnitt 12 verläuft, wie ersichtlich, schräg zur Drehachse der Welle 10, wodurch das Schneidrad 5 nach dem Einstecken des Elementeträgers 11 in die gewünschte Schräglage gelangt.The rotary handle 4 has a shaft 10 which extends through an element carrier 11 and carries the cutting wheel 5 and the gear 6 at its free end. To fasten the element carrier 11 to the arm 1, the arm 1 is provided with a cutout 12 (FIG. 4) and the element carrier 11 on its peripheral surface with an incision 13 (FIG. 5). The width of the incision 13 corresponds to the thickness of the arm 1 formed by a sheet metal part and its core to the width of the cutout 12. The element carrier 11 is inserted with its incision 13 into the cutout 12 and held non-positively. The cut 12 runs, as can be seen, at an angle to the axis of rotation of the shaft 10, as a result of which the cutting wheel 5, after the element carrier 11 has been inserted, comes into the desired inclined position.

Das Zahnrad 8 sitzt fest auf der Welle 14 des Vorschubsrades 7. Die Achse 14 hat an ihrem vom Vorschubrad 7 abgewandten Ende einen Abschnitt 15 größeren Durchmessers. Zur Aufnahme dieser Einheit ist der zweite Arm 2 mit einem Schlitz 16 (Fig. 3) versehen, in den die Welle 14 kraftschlüsig eingeschoben ist.The gear wheel 8 is firmly seated on the shaft 14 of the feed wheel 7. The axis 14 has a section 15 of larger diameter at its end facing away from the feed wheel 7. To accommodate this unit the second arm 2 is provided with a slot 16 (FIG. 3) into which the shaft 14 is inserted in a force-locking manner.

Da der Ausschnitt 12 und der Schlitz 16 an den einander zugewandten Innenkanten der Arme 1,2 vorgesehen sind, wird vermieden, daß der Elementeträger 11 und die Einheit 7,8 beim Zusammendrücken der Arme aus dem Auschnitt 12 bzw. aus dem Schlitz 16 herausgedrückt werden.Since the cutout 12 and the slot 16 are provided on the mutually facing inner edges of the arms 1, 2, it is avoided that the element carrier 11 and the unit 7, 8 are pressed out of the cutout 12 or out of the slot 16 when the arms are pressed together .

In den Fig. 6 und 7 ist ein zweites Ausführungsbeispiel für den zweiten Arm 2 und die auf diesen aufgesteckte Einheit aus Vorschubrad 7 und Zahnrad 8 dargestellt. Hierbei ist die Welle 14 dieser Einheit in einem Kunststoff-Teil 17 gelagert, das einen Schlitz 18 aufweist, der sich in einer Nut 19 zu beiden Seiten der Lagerstelle für die Welle 14 fortsetzt. Der Arm 2 hat einen Ausschnitt 20, in den das Kunststoff-Teil 17 eingeschoben wird und in dem es formschlüssig gehalten ist. An das Kunststoff-Teil 17 ist der Abstandshalter 9 angeformt, der bei dem vorhergehenden Beispiel von einem aus der Ebene des Armes 2 herausgebogenen Lappen gebildet ist.6 and 7, a second exemplary embodiment of the second arm 2 and the unit comprising the feed wheel 7 and the gear wheel 8 are shown. Here, the shaft 14 of this unit is mounted in a plastic part 17, which has a slot 18, which continues in a groove 19 on both sides of the bearing point for the shaft 14. The arm 2 has a cutout 20 into which the plastic part 17 is inserted and in which it is held in a form-fitting manner. The spacer 9 is formed on the plastic part 17 and, in the previous example, is formed by a tab bent out of the plane of the arm 2.

Abweichend von den vorstehend beschriebenen Ausführungsbeispielen kann das Schneidrad 5 auch auf der Welle 14 und das Vorschubrad 7 auf der Welle 10 angeordnet werden.In a departure from the exemplary embodiments described above, the cutting wheel 5 can also be arranged on the shaft 14 and the feed wheel 7 on the shaft 10.

In den Fig. 8 bis 10 sind die Einzelteile eines weiteren Ausführungsbesipieles dargestellt. In dem in Fig. 8 dargestellten Elementeträger 11 ist wie in Fig. 5 die Welle 10 des Drehgriffes 4 gelagert. Unterschiedlich gegenüber der Ausführung von Fig. 5 ist, daß auf der Welle 10 neben dem Schneidrad 5 auch das Vorschubrad 7' angebracht ist. Der Elementeträger 11 wird, wie in Zusammenhang mit Fig. 4 und 5 beschrieben, in den Ausschnitt 12 des ersten Armes 1 eingesteckt. Der zweite Arm 2' ist an seiner dem ersten Arm zugewandten Kante mit einem Stützelement 21 versehen, das, wie schematisch in Fig. 10 gezeigt, die Randwulst einer zu öffnenden Dose untergreift und gegenüber dem Schneidrad 5 abstützt. Das Stützelement 21 kann zur Verringerung der Reibung von einer Rolle gebildet sein. Der Arm 2' ist außerdem ähnlich wie in Fig. 1 mit einem Abstandshalter 9 versehen. Das Stützelement 21 und der Abstandshalter 9 sind von Lappen gebildet, die aus der Ebene des aus einem Blechteil bestehenden Armes 2' herausgebogen sind.8 to 10 show the individual parts of a further exemplary embodiment. In that shown in Fig. 8 5, the shaft 10 of the rotary handle 4 is mounted as in FIG. Different from the embodiment of FIG. 5 is that in addition to the cutting wheel 5, the feed wheel 7 'is also mounted on the shaft 10. The element carrier 11 is, as described in connection with FIGS. 4 and 5, inserted into the cutout 12 of the first arm 1. The second arm 2 'is provided on its edge facing the first arm with a support element 21 which, as shown schematically in FIG. 10, engages under the rim of a can to be opened and supports it with respect to the cutting wheel 5. The support element 21 can be formed by a roller in order to reduce the friction. The arm 2 'is also provided with a spacer 9 similar to that in FIG. 1. The support element 21 and the spacer 9 are formed by tabs which are bent out of the plane of the arm 2 'consisting of a sheet metal part.

Abweichend von den dargestellen Ausführungsbeispielen kann, wie bekannt, anstelle des Scheidrades auch ein feststehende Messer vorgesehen werden.In a departure from the exemplary embodiments shown, as is known, a fixed knife can also be provided instead of the cutting wheel.

Wie ersichtlich, werden bei allen Ausführungsbeispielen die für das öffnen der Dose erforderlichen drehbaren Elemente, also insbesondere das Scheidrad und das Vorschubrad sowie gegebenenfalls zur übertragung der Drehbewegung des Drehgriffes vorgesehene Zahnräder zu Einheiten zusammengefaßt, die einfach auf die Arme des Dosenöffners aufgesteckt werden. Dadurch wird die Herstellung und der Zusammenbau des Dosenöffners wesentlich vereinfacht.As can be seen, in all of the exemplary embodiments, the rotatable elements required for opening the can, in particular the cutting wheel and the feed wheel and, if appropriate, gears provided for transmitting the rotary movement of the rotary handle are combined into units which are simply plugged onto the arms of the can opener. This significantly simplifies the manufacture and assembly of the can opener.
