Abstract

A housing for a paper shredder with a slit-like paper feed disposed on one side of the housing and a slit-like paper discharge disposed on the opposite side of the housing. The housing has an elongated shape, the dimension of length being a multiple of the dimension in width, where on each narrow side of the paper discharge support surfaces are disposed, with which the paper shredder can be placed on a waste receptacle. The width of the support surface is selected such, that one of the support surfaces is considerably larger than the width of the edge of the waste receptacle, while the other support surface has a width only negligibly greater than the width of the edge of the waste receptacle. It is additionally possible to provide a clamping device in the area of one support surface as security against sliding of the paper shredder placed on the waste receptacle.

Description

Gegenstand der Erfindung nach dem Oberbegriff des Anspruchs 1 ist ein Gehäuse für einen Aktenvernichter mit einem spaltförmigen Papiereinlaß auf der einen Seite des Gehäuses und einem spaltförmigen Papierauslaß auf der gegenüberliegenden Seite des Gehäuses.The invention according to the preamble of claim 1 is a housing for a paper shredder with a gap-shaped paper inlet on one side of the housing and a gap-shaped paper outlet on the opposite side of the housing.

Aus der US-A-3724766 ist bereits bekannt, einen derartigen Aktenvernichter länglich auszubilden, und mit seitlich angeordneten Auflageflächen zu versehen, wobei die eine Auflagefläche über ausziehbare Schienen am Gehäuse des Aktenvernichters befestigt ist, so daß eine Anpassung an die Breite des Abfallbehälters erfolgen kann.From US-A-3724766 it is already known to form such a paper shredder elongated, and to provide it with laterally arranged support surfaces, the one support surface being attached to the housing of the paper shredder via pull-out rails, so that it can be adapted to the width of the waste container .

Weiterhin ist es aus der DE-B-1294802 bekannt, einen handbetriebenen Papiervernichter mit einer Klemmanordnung auszustatten. Zweck dieser Klemmanordnung ist es, den Aktenvernichter, wegen der durch den Handbetrieb verursachten hohen Kräfte, an einem stabilen Gegenstand wie z.B. einer Tischplatte festzulegen, und so den Betrieb erst zu ermöglichen.Furthermore, it is known from DE-B-1294802 to equip a hand-operated paper shredder with a clamping arrangement. The purpose of this clamping arrangement is to fix the document shredder to a stable object, such as a table top, because of the high forces caused by manual operation, and thus to enable operation.

Aktenvernichter der vorstehend genannten Art sind auch häufig so ausgebildet, daß sie auf einen für den jeweiligen Aktenvernichter bestimmten und entsprechend geformten Abfallbehälter direkt aufsetzbar sind oder sie befinden sich auf einem Tragegestell unter das ein konventioneller Abfallbehälter gestellt werden kann, so daß die Papierabfälle direkt von diesem aufgenommen werden können.Document shredders of the type mentioned above are also often designed so that they can be placed directly on a waste container intended for the respective shredder and shaped accordingly, or they are located on a support frame under which a conventional waste container can be placed, so that the paper waste can be removed directly from it can be included.

Ungünstig bei derartigen Anordnungen ist, daß in dem einen Fall der Abfallbehälter direkt mit dem Aktenvernichter verbunden ist und deshalb nicht für andere Zwecke zur Verfügung steht und im anderen Fall der Abfallbehälter so unter dem Aktenvernichter angeordnet ist, daß er für die Aufnahme von anderem Abfall erst unter dem Aktenvernichter hervorgeholt werden muß.A disadvantage of such arrangements is that in the one case the waste container is connected directly to the shredder and is therefore not available for other purposes and in the other case the waste container is arranged under the shredder in such a way that it only takes up other waste must be brought out from under the shredder.

Ausgehend vom vorstehend aufgezeigten Stand der Technik ist es Aufgabe der Erfindung, ein Gehäuse für einen Aktenvernichter so auszubilden, daß der Aktenvernichter auf Abfallbehälter unterschiedlichster Art lagesicher auflegbar ist und die sonstige Benutzung des Abfallbehälters nur unwesentlich beeinflußt.Starting from the prior art shown above, it is an object of the invention to provide a housing for a document shredder in such a way that the document shredder can be placed securely on a wide variety of types of waste containers and has only an insignificant effect on the other use of the waste container.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Advantageous developments of the invention are characterized in the subclaims.

Eine noch weitergehende Sicherung gegen das Verrutschen des auf den Abfallbehälter aufgelegten Aktenvernichters wird durch eine Klemmvorrichtung gemäß dem Kennzeichen der Ansprüche 2, 3 und 4 erreicht.A still further protection against slipping of the document shredder placed on the waste container is achieved by a clamping device according to the characterizing part of claims 2, 3 and 4.

Ein Beispiel der Erfindung ist nachfolgend unter Zuhilfenahme der Zeichnung näher erläutert. Die Figur zeigt die Stirnfläche und die Seitenansicht eines im wesentlichen zylinderförmig ausgebildeten Aktenvernichters 1, der auf seiner einen Seite einen spaltförmigen Papiereinlaß 2 und auf der gegenüberliegenden Seite einen spaltförmigen Papierauslaß 3 aufweist. Auf beiden Seiten des Papierauslasses 3 sind Auflageflächen 4 und 5 vorgesehen, die durch eine Abflachung des zylinderförmigen Gehäuses gebildet werden. Ein die eine Stirnseite des Gehäuses des Aktenvernichters abschließender Gehäusedeckel 6 steht unter der Wirkung einer Feder (nicht dargestellt), wobei die Feder in Richtung auf eine Anlagefläche 7 wirkt, die die Auflagefläche 4 in Richtung auf den Papierauslaß 3 hin abgrenzt.An example of the invention is explained in more detail below with the aid of the drawing. The figure shows the end face and the side view of a substantially cylindrical document shredder 1, which has a slit-shaped paper inlet 2 on one side and a slit-shaped paper outlet 3 on the opposite side. Support surfaces 4 and 5 are provided on both sides of the paper outlet 3 and are formed by flattening the cylindrical housing. A housing cover 6 which closes one end face of the housing of the document shredder is under the action of a spring (not shown), the spring acting in the direction of a contact surface 7 which delimits the support surface 4 in the direction of the paper outlet 3.

Durch die relativ breite Ausbildung der Auflagefläche 5 wird die Möglichkeit geschaffen, den Aktenvernichter auf Abfallbehälter 8 unterschiedlichster Breite aufzulegen, die Klemmvorrichtung die durch den unter Federwirkung stehenden Gehäusedeckel 6 und die Anlagefläche 7 gebildet wird, sichert den auf den Abfallbehälter 8 aufgelegten Aktenvernichter 1 vor dem Verrutschen.The relatively wide design of the support surface 5 creates the possibility of placing the document shredder on waste container 8 of various widths, the clamping device formed by the spring-loaded housing cover 6 and the contact surface 7 secures the document shredder 1 placed on the waste container 8 from the Slipping.

Eine andere Möglichkeit in Verbindung mit der Auflagefläche 4 bzw. mit der Anlagefläche 7 eine Klemmvorrichtung zu realisieren besteht darin, am Gehäusedeckel 6 ein Gewinde anzuordnen (nicht dargestellt) das mit einem am Gehäuse des Aktenvernichters 1 angeordneten Gegenstück zusammenwirkt derart, daß durch das Verdrehen des Gehäusedeckels 6 in Richtung des Pfeiles A dieser eine Bewegung in Richtung des Pfeiles B ausführt. Auf diese Weise wird bei auf einen Abfallbehälter 8 aufgelegten Aktenvernichter 1 der Rand des Abfallbehälters 8 zwischen dem Gehäusedeckel 6 und der Anlagefläche 7 eingeklemmt und der Aktenvernichter 1 so gegen Verrutschen gesichert.Another possibility in connection with the support surface 4 or with the contact surface 7 to realize a clamping device is to arrange a thread on the housing cover 6 (not shown) which interacts with a counterpart arranged on the housing of the document shredder 1 in such a way that by rotating the Housing cover 6 in the direction of arrow A this performs a movement in the direction of arrow B. In this way, the edge of the waste container 8 is clamped between the housing cover 6 and the contact surface 7 when the document shredder 1 is placed on a waste container 8 and the document shredder 1 is thus secured against slipping.

In einer vereinfachten Ausführungsform ist es selbstverständlich möglich auf die Klemmwirkung, die in Verbindung mit der Auflagefläche 4 und der Anlagefläche 7 beschrieben ist zu verzichten. In diesem Falle ist die Auflagefläche 4 so schmal gehalten, daß die Anlagefläche 7 und der Gehäusedeckel 6 bei auf den Abfallbehälter 8 aufgelegtem Aktenvernichter 1 nur eine sehr begrenzte Bewegung in Horizontalrichtung zulassen.In a simplified embodiment, it is of course possible to dispense with the clamping action that is described in connection with the contact surface 4 and the contact surface 7. In this case, the contact surface 4 is kept so narrow that the contact surface 7 and the housing cover 6 permit only a very limited movement in the horizontal direction when the document shredder 1 is placed on the waste container 8.

Abschließend ist noch darauf hinzuweisen, daß der Gehäusedeckel 6 durch einen festen Gehäuseabschluß ersetzt sein kann. Die gewünschte Klemmwirkung läßt sich dann durch einen Ring erzielen, der im Bereich des der Auflagefläche 4 benachbarten Gehäuseabschlusses mittels eines Innengewindes auf das Gehäuse, das über ein entsprechendes Außengewinde verfügt, aufschraubbar ist.Finally, it should be pointed out that the housing cover 6 can be replaced by a fixed housing closure. The desired clamping effect can then be achieved by means of a ring which can be screwed onto the housing in the area of the housing closure adjacent to the bearing surface 4 by means of an internal thread, which has a corresponding external thread.
