Description

Die Erfindung bezieht sich nach dem Oberbegriff des Patentanspruches 1 auf die Ausgestaltung eines Untergestells für Papierzerkleinerer, vor allem bei sog. Aktenvernichtern o.ä.The invention relates to the preamble of Claim 1 on the design of a base for paper shredders, especially for so-called Shredders or similar

Bislang bekannte offene Untergestelle besitzen entweder keine, die Seitenteile verbindende Grundplatte, was zu Verschmutzungen des Bürobodens durch Schneidpartikel führen kann, oder aber sie sind starre, kastenartige Gebilde unterschiedlichster Bauart, die nicht nur viel Lager- und Transportraum benötigen, sondern zudem zumeist noch kompliziert und damit kostenaufwendig herzustellen und/oder zu montieren sind.Previously known open bases either have no base plate connecting the side parts, resulting in contamination of the office floor by cutting particles can lead, or they are rigid, box-like structures Different designs, which not only have a lot of storage and transport space need, but also mostly complicated and thus costly to manufacture and / or assemble are.

Die DE-OS-22 35 010 beschreibt einen zerlegbaren Behälter mit rechteckigem Bodenrahmen und oberem Profilrahmen, wobei die Seitenwände des Behälters mit den Profilrahmen lösbar verbindbar sind, und daher der Behälter leicht zerlegbar ist. Auf den Behälter wird ein Reißwolf aufgesetzt. Der Behälter benötigt zwar beim Transport in zerlegtem Zustand wenig Platz, als nachteilig hierbei ist jedoch anzusehen, dass die Seitenwände an den verschiedenen Profilrahmen über Verschraubungen befestigt werden müssen. Die Rahmen verleihen dem zusammengesetzten Behälter seine Formstabilität.DE-OS-22 35 010 describes a collapsible container rectangular floor frame and upper profile frame, the Side walls of the container releasably connectable to the profile frame are, and therefore the container is easy to disassemble. On the A shredder is placed on the container. The container needed little space when transported in disassembled state, as disadvantageous however, it can be seen that the side walls on the various profile frames attached via screw connections Need to become. The frames give the composite Container its dimensional stability.

Die Aufgabe der vorliegenden Erfindung besteht deshalb auch darin, ein einfach zu fertigendes und zusammenzubauendes Untergestell der hier zur Rede stehenden Art zu schaffen, das die zuvor aufgeführten Nachteile bekannter Ausführungen beseitigt. The object of the present invention therefore also exists in being an easy to manufacture and assemble To create underframe of the type in question here, the the disadvantages of known designs listed above eliminated.

Gelöst wird diese Aufgabe in überwiegender Weise durch die im Kennzeichen des Patentanspruches 1 angegebenen baulichen Mittel und Ausgestaltungsmaßnahmen. Die Unteransprüche zeigen vorteilhafte Weiterbildungen und notwendige Ausgestaltungsmerkmale des erfinderischen Grundgedankens auf, die zudem anhand eines Ausführungsbeispieles in den Zeichnungen dargestellt und anhand dieser im Detail nachfolgend noch näher erläutert sind. Es zeigen im einzelnen:

Fig. 1
eine perspektivische "Explosionsdarstellung" des neuen Untergestells,
Fig. 2
das wesentlichste Einzelteil des neuen Gestells in seiner Ausgangsform und
Fig. 3
einen ersten Montageschnitt des Bauteils nach Fig. 2.
This object is largely achieved by the structural means and design measures specified in the characterizing part of claim 1. The subclaims show advantageous further developments and necessary design features of the inventive concept, which are also shown in the drawings using an exemplary embodiment and are explained in more detail below with reference to this. The individual shows:
Fig. 1
a perspective "exploded view" of the new base,
Fig. 2
the most essential single part of the new frame in its original form and
Fig. 3
a first assembly section of the component of FIG. 2nd

Das in Fig. 1 dargestellte neue Untergestell besteht in seinem Grundaufbau aus zwei parallel zueinander liegenden, formstabilen Seitenteilen 1 und 2 mitsamt diese verbindendem Boden 3 und Rückwand 4 sowie dem auf letztere und die Seitenteile 1, 2 zur Komplettierung lösbar aufgesetztem Schneidwerksgehäuse.The new base shown in Fig. 1 exists in its basic structure of two parallel to each other horizontal, dimensionally stable side parts 1 and 2 together this connecting floor 3 and rear wall 4 and the on the latter and the side parts 1, 2 to complete detachably mounted cutting unit housing.

Das Neue und die Lösung der eingangs gestellten Aufgabe Ermöglichende besteht nun darin, daß

  • zum einen Rückwand 4 und Bodenfläche 3 aus einer in ihrer Ausgangsform (Fig. 2) einstückigen, ebenflächigen Platte PL mit querverlaufender Biegenut BN zwischen Boden- und Rückwandbereich 3 und 4 besteht,
  • wobei diese Platte PL beim Zusammenbau des Untergestells (Fig. 1) über aufsteckbare-Pfeile P1 und P2,-entsprechend profilierte Seitenteile 1 und 2 in einer um 90° abgewinkelten Lage (Fig. 3) gehalten ist und
  • letztlich die Seitenteile 1 und 2 Über ebenfalls steckbare, in mindestens zwei mit gegenseitigem Vertikalabstand VA zueinander liegenden Ebenen VE1 und VE2 angeordnete Anschlußstellen 6 und 7 für das Schneidwerksgehäuse 5 mit letzterem ein starres, kastenartiges Bauteil bilden.
The novelty and the solution of the task made possible at the beginning consists in the fact that
  • on the one hand, rear wall 4 and base surface 3 consist of a flat plate PL in its initial shape (FIG. 2) with a transverse bending groove BN between base and rear wall regions 3 and 4,
  • wherein this plate PL is held in the assembly of the base (Fig. 1) via attachable arrows P 1 and P 2 , correspondingly profiled side parts 1 and 2 in a 90 ° angled position (Fig. 3) and
  • ultimately the side parts 1 and 2 via likewise pluggable, in at least two mutually vertical spacing VA arranged VE 1 and VE 2 arranged connection points 6 and 7 for the cutting unit housing 5 with the latter form a rigid, box-like component.

Eine besonders vorteilhafte und einfache Fertigung, vornehmlich als Kunststoffspritzteil, ist nun dadurch möglich, daß die in die Seitenteile 1 und 2 eingreifenden Steckelemente 3a, 3b und 4a, 4b von Boden- und Rückwandbereich 3 und 4 der Platte PL als ebenflächige Stecklaschen 3a und 4a und/oder hakenförmige Schnappverschlüsse 3b und 4b ohne Hinterschneidungen ausgebildet sind; die wechselweise fortlaufende Anordnung von Steck- und Schnappverbindern 3a, 3b und 4a, 4b an den den formstabilen Seitenteilen 1 und 2 zugewandeten Außenkanten AK von Boden- und Rückwandplatte 3 und 4 ergibt eine feste und jederzeit betriebssichere Verbindung der drei losen, ebenflächigen Ausgangsbauteile 1, 2 und PL.A particularly advantageous and simple production, primarily as a plastic injection molded part, is now due to this possible that the engaging in the side parts 1 and 2 Plug-in elements 3a, 3b and 4a, 4b from floor and Back wall area 3 and 4 of the plate PL as a flat surface Push-in tabs 3a and 4a and / or hook-shaped snap closures 3b and 4b formed without undercuts are; the alternately continuous arrangement of plug and snap connectors 3a, 3b and 4a, 4b on the dimensionally stable side parts 1 and 2 Outer edges AK of the bottom and rear wall panels 3 and 4 results in a fixed and reliable at all times Connection of the three loose, flat Output components 1, 2 and PL.

Die absolute statische Stabilität im Fertigzustand wird für das neue Untergestell zusätzlich noch dadurch erreicht, daß die Anschlußstellen 6, 7 sowie 8,9 für das Schneidwerksgehäuse 5 neben den vertikalen voneinander beabstandeten Bereichen VE1 und VE2 auch in horizontalter Ebene HE1 und HE2 je Seitenteil 1 und 2 versetzt HA zueinander liegen, wobei in spezieller Ausgestaltung diese Anschlußstellen 6 bis 9 für das Schneidwerksgehäuse 5 als von oben steckbare Aussparungen 6 und 7 an entsprechenden Rippen 1a, 1b und 2a, 2b der Seitenteile 1 und 2 und dazu formschlüssig korrespondierende Zapfen 8 und 9 beliebiger Querschnittsform an der Schneidwerksunterseite 5b ausgebildet sind.The absolute static stability in the finished state is additionally achieved for the new underframe in that the connection points 6, 7 and 8.9 for the cutting unit housing 5 in addition to the vertically spaced apart areas VE 1 and VE 2 also in the horizontal plane HE 1 and HE 2 HA for each side part 1 and 2 are offset from one another, in a special embodiment these connection points 6 to 9 for the cutting unit housing 5 as recesses 6 and 7 which can be plugged in from above on corresponding ribs 1a, 1b and 2a, 2b of the side parts 1 and 2 and correspondingly form-fitting Pins 8 and 9 of any cross-sectional shape are formed on the underside 5b of the cutting unit.

Sinnvoll ist letztlich noch ein zusätzliches kraftschlüssiges Sicherungselement 10 gegen Abheben zwischen Schneidwerksgehäuse 5 und jedem der Seitenteile 1 und 2, vorteilhafterweise ebenfalls im Bereich der Rippen 1b und 2b angreifend.In the end, it makes sense to have an additional force-fit Securing element 10 against lifting between Cutting unit housing 5 and each of the side parts 1 and 2, advantageously also in the area of Attacking ribs 1b and 2b.
