EP0616851B1 - Document shredder with collection bag for the shredded material - Google Patents

Description

The invention relates to a document or document shredder according to the Preamble of claim 1.

Such a shredder is known from DE-PS 39 22 313. Of the Document shredder of this document has a holding frame with on the side guide webs arranged outside the area of the bag. The Guide bars protrude beyond the inner part of the holding frame and are in the guides arranged on the housing of the document shredder kept slidable. The holding frame is for changing the bag completely removable from the guides.

This known construction is not only structurally very complex, it also has no security that the front housing is secure closed and the device remains dustproof when the Suspended clippings bag expands on all sides with increasing filling while pushing against the front door.

The invention has for its object in a generic Document shredders on the one hand make changing bags easier, and through a handy simple and reliable design of the Holding frame and the guides, as well as other measures to provide the press-on the front housing door through which is in operation prevent expanding clippings bag.

This task is solved in a general way the structural means specified in claim 1 and measures. The subclaims contain advantageous ones Further training of the new system.

A preferred embodiment of the invention is also shown in the drawings and based on this is explained in more detail below.

The perspective in Fig. 1 in its basic structure Document shredder shown consists of the containing the cutting unit, not shown Housing head part 1 and the housing base, formed through the housing side walls 1b with their front Bends 1c, the housing base 1e and the front located here in the open position Housing door 2, 2a. It can also be seen the front cross connection 5a of the holding frame 5 for the waste bag or clippings bag 6 the with its frame side parts 5 on telescopic or similar via roller guides 8 on the inside of the Housing side walls 1b mounted, angular Guide rails 4 from the housing interior 1 'horizontally is completely withdrawable for emptying.

a. Der Halterahmen 5, 5a für den Schnittgutbeutel 6 ist zusammen mit letzterem lose auf die ausfahrbaren seitlichen Führungsschienen 4 aufgelegt.

b. Die Führungsschienen 4 besitzen frontseitige Anschlagelemente 7, 7a, einerseits für die Arretierung der vorderen Querverbindung 5a des Halterahmens 5 auf den Führungsschienen 4 gegen horizontales Herausgleiten und andererseits zur Verhinderung einer öffnenden Druckkraft durch den sich füllenden Schnittgutbeutel 6 auf die frontseitige Gehäusetür 2.

c. Der Halterahmen 5 für den Schnittgutbeutel 6 besitzt etwa mittig an seiner frontseitigen Querverbindung 5a einen zum Gehäuseboden 1e hin gerichteten, bügelförmigen Anschlag 5b.

The novelty of such a document shredder can now be seen in the combinatorial interaction of the following features:

a. The holding frame 5, 5a for the clippings bag 6, together with the latter, is loosely placed on the extendable side guide rails 4.

b. The guide rails 4 have stop elements 7, 7a on the front, on the one hand for locking the front cross-connection 5a of the holding frame 5 on the guide rails 4 against horizontal sliding out and on the other hand to prevent an opening pressure force by the filling clippings bag 6 on the front housing door 2.

c. The holding frame 5 for the clippings bag 6 has a bow-shaped stop 5b directed towards the housing base 1e approximately in the center of its cross connection 5a at the front.

It is also provided that that there is at least one stop element 7 on the head side running transversely on the door hinge side 3, 3a lying guide rail 4, 4a and be protruding free end 7a when the front door of the housing is closed 2 behind the pivot axis 3a of the door hinges 3 rests on the inside of the door 2a. One for the function from point c. is extremely advantageous embodiment can still be seen in the fact that the bow-shaped stop 5b designed as a closed U-shaped frame on the bottom is slightly inward to the interior 1 'of the housing 1 runs and in the area of the front cross connection 5a of the holding frame 5 one at a distance additional crossbar below the latter 5c.

So if the clippings collection bag or waste collection bag expands with increasing filling, prevented first of all the slightly inward-looking Stop bracket 5b by its bias that the Large sack extension in the area of the door center presses on the front door 2 and this opens. Small bulges of the sack in the Edge zones of the door also do not lead to any undesirable Opening the latter because these forces with the lever arm "a" the behind the door hinge or its pivot axis 3a holding force of the projecting free end 7a of the transverse, strip-shaped stop element 7 from the angular Guide rail 4, counteracts. It makes sense here is still when the angular guide rails 4, 4a together with the stop element 7, 7a above of the upper door hinge 3, 3a are arranged, that is are on two different levels.

Ultimately, the invention described above the damage-free removal of the full Garbage bag made much easier by both sides the housing front 1a on the inner walls of the housing side parts 1b arranged sliding plates 1d, starting from the bevels 1c and running inwards towards the inner walls of the housing.
