Description

Territory of invention

The The present invention relates to a document shredder, in particular a shredder construction with a vertically separated Drive.

background the invention

• 1. Die beim Betrieb des Motors entstehende Wärme und die bei der Messergruppe durch Reibung entstehende Warme addieren sich. Deshalb erhöht sich nach kurzer Zeit die Temperatur, und das Gerät kann nicht rasch gekühlt werden. Dies führt zu einem vergleichsweise instabilen und unsicheren Betrieb. Und weil das Gehäuse des Aktenvernichters deshalb aus besonders schwerentzündlichem Material bestehen muss, darf eine solche Aktenvernichtungskonstruktion mit parallelem Antrieb nicht über einen längeren Zeitraum betrieben werden.
• 2. Da bei einer solchen Aktenvernichtungskonstruktion mit parallelem Antrieb der Motor und die Messergruppe nahe beieinander und horizontal nebeneinander angeordnet sind, sind derzeit auf dem Markt erhältliche Aktenvernichter vergleichsweise groß. Folglich wird viel Material verbraucht; außerdem ist das Design eintönig. Außerdem gibt es noch folgendes Problem: der Schwerpunkt des Gerätes liegt vergleichsweise weit oben, was zu einem instabilen Standverhalten führt, insbesondere wenn der Aktenvernichter eine vergleichsweise große Kapazität aufweisen soll. Ein großer bzw. hoher Aktenvernichter kann nur auf dem Boden aufgestellt werden. Es ist somit nicht möglich, jeden Arbeitsplatz mit einem Aktenvernichter auszurüsten, insbesondere mit einem Aktenvernichter von großer Kapazität. Wenn mehrere Mitarbeiter denselben Aktenvernichter nutzen müssen, mindert dies ohne Zweifel die Arbeitsleistung.

Currently, the known shredders use a construction with parallel drive. The parallel drive construction means: the motor and the blade group are supported close to each other on a common support extending horizontally. Such a construction has the following disadvantages in particular:

• 1. The heat generated during operation of the engine and the heat generated by friction in the blade group add up. Therefore, the temperature increases after a short time, and the device can not be cooled quickly. This leads to a comparatively unstable and unsafe operation. And because the shredder's housing therefore has to be made of a material that is particularly difficult to ignite, such a shredding construction with a parallel drive must not be operated for a long period of time.
• 2. Since in such a shredding construction with parallel drive, the motor and the blade group are arranged close to each other and horizontally next to each other, document shredders currently available on the market are comparatively large. Consequently, much material is consumed; In addition, the design is monotonous. There is also the following problem: the center of gravity of the device is comparatively high up, which leads to an unstable stand-still, especially if the shredder should have a comparatively large capacity. A large or high shredder can only be placed on the floor. It is therefore not possible to equip each workstation with a shredder, especially with a large capacity shredder. If several employees have to use the same document shredder, this undoubtedly reduces the workload.

Summary of the invention

task It is thus the object of the present invention to overcome the aforementioned disadvantages a shredder with parallel drive at least partly to remedy. In particular, overheating should be avoided and the size of the device should be reduced become.

These and further objects are achieved according to the invention in that a shredding device with a vertically separated drive provided.

A Shredding device according to the present invention The invention with vertically separated drive comprises a motor, a Knife group and a carrier. According to the invention Motor and knife group, viewed in the vertical direction, on two ends of a vertically extending support provided. That The motor is attached to the lower end of the vertically extending support and the knife group is at the upper end of the vertically extending carrier appropriate. There is room between the engine and the blade group, the for a collection container is available for catching paper shreds. A transmission device connects the blade group to the engine.

The Transmission device may be a gear transmission device or a Tape roller mechanism or a chain transmission device be.

The Design principle according to the present invention is thus based in particular on an increase in the distance between the engine and the blade group, reducing the speed the temperature increase shredder, improving the operational stability of the shredder, an extension the life and an increase the work performance. Because of the engine and the blade group vertically spaced from each other and are arranged separately the weight centers are divided more evenly. Furthermore can the width of the device be reduced without the installation of the collection container for shredded paper impaired becomes.

The Shredding construction according to the invention with separate and vertical transmission has an economic Construction. It solves in particular the following problems of the Previous document shredding facilities: conventional is the focus too high up, conventional are size, material consumption, instability the operating behavior due to heat generation and the design options inadequate in design.

• 1. Der Motor und die Messergruppe sind thermisch im Wesentlichen nicht gekoppelt und kühlen deshalb separat, so dass die Unsicherheit reduziert wird und die Betriebszeit der Maschine verlängert wird.
• 2. Der Schwerpunkt des Aktenvernichters ist weiter nach unten verlagert. Das Gerät steht somit besser und sicherer.
• 3. Die Größe kann enorm reduziert werden, wodurch Material eingespart werden kann. Der beanspruchte Raum ist erfindungsgemäß kleiner.
• 4. Die Aktenvernichtungseinrichtung mit getrenntem und vertikalem Antrieb ist vergleichsweise schmal. Somit können Aktenvernichter nur von der Größe eines Aktenordners hergestellt werden. Es bestehen mehr Designmöglichkeiten.
• 5. Der erfindungsgemäß verkleinerte Aktenvernichter eignet sich gut für die Ausstattung von Schreibtische. Dadurch wird die Effektivität bei der Arbeit erhöht, insbesondere weil Dokumente rechtzeitig vernichtet werden können. Dadurch wird auch die Datensicherheit erhöht.

The claimed subject matter in particular has the following advantages:

• 1. The engine and blade assembly are essentially thermally uncoupled and therefore cool separately so that uncertainty is reduced and engine uptime is increased.
• 2. The center of gravity of the shredder is moved further down. The device is thus better and safer.
• 3. The size can be greatly reduced where can be saved by material. The claimed space is smaller according to the invention.
• 4. The shredder with separate and vertical drive is relatively narrow. Thus, document shredders can only be made the size of a file folder. There are more design options.
• 5. The inventively shrunk shredder is well suited for the equipment of desks. This increases the effectiveness of the work, especially because documents can be destroyed in time. This also increases data security.
