Abstract

A paper shredder comprises a cupboard-like substructure (3), Fig. 2, supporting a shredder device (1) and tiltable-out paper deposit flaps (4) Fig. 3, at its front side. The flaps are carried by a frame (5) which is constructed as a door (7) pivotably mounted by way of hinges (8) at a lateral edge of the substructure. Even when the flaps (4) are filled with paper, the door can be fully opened for access to a waste paper collection receptacle within the substructure. <IMAGE>

Description

SPECIFICATION Paper shredder The present invention relates to a paper shredder.

Paper shredders have been on the market from Japanese manufacturers for some time,forexample the model S420 ofthefirm MEIKOSHOKAI COMPANY LIMITED, Tokyo. Compared with earlier models, in which the tiltable-out paper deposit flaps were integrated in a fixed front of a cupboard-like substructure so that an internal paper-collecting sack or other container could be replaced only from the rear side after moving the entire equipment away from a wall, the model S420 with its forward front withdrawable as a whole represents a relative improvement which, however, is lost when a change of waste sack is required while the deposit flaps are still full of paper.Asingle operatorcannotcarrythe entire load and theflap cannot besupported in its use position, because the centre of gravity ofthe paper is too farforward and the support surface of the frame is too small.

Itwould thus be desirable to provide equipment in which removal of a fu 11 waste sack or other receptacle may be possible at the front even in the case offilled paper deposit surfaces.

According to the present invention there is provided a paper shredder comprising a housing substructure supporting a shredding device and defining a space accommodating a receptacle for shredded paperfalling from the device and a door which is mounted by hinge means to the substructure at a lateral boundary edge thereof to be pivotable about a substantially vertical axis for opening and closing of an access opening provided at the front of the substructure for insertion and removal of such receptacle and which comprises a frame and a plurality offlaps which are arranged one above the other and pivotably mounted to the frame to be movable between a first setting in which they lie in the general plane of afrontface oftheframe and a second setting in which they extend substantially horizontally out from the frame to serve as deposit surfaces for paper, the hinge means being arranged to perriiil movement of the doorto fully open the ,ccess ,cess opening when the flaps are in either of said settings.

An embodimentofthe presentinventionwill now be more particularlydescribed bywayofexample with reference to the accompanying drawings, in which: Figure lisa front elevation of a paper shredder embodying the invention; Figure2 is a plan view of the shredder of Figure 1; and Figure 3 is a side elevation, in section and to an enlarged scale, of part of a door ofthe shredder.

Referring now to the drawings, there is shown a papershreddercomprising a shredder device 1 with shredder mechanism 2 and a cupboard-like housing substructure 3 which supports the device 1.

Arranged at the front of the substructure arethree paper deposit trays or flaps 4, which are disposed one above the other and recessed into the front side in coplanar arrangement. The flaps are at least partially tiltable out of the front side into an approximately horizontal position for reception of, for example, computer paper or similar stationery.

Theflaps4are held in aframe 5, which in its turn is movable away from the front side of the substructure 3 to provide access to a waste-collecting sack or container 6, which is hooked in therebehind, for finelycomminuted material falling outofthe shredding mechanism 2.

The frame 5 is constructed as a door 7, which is mounted by door hinges 8 and pivotable open laterally about a substantially vertical axis x. The hinges 8 are arranged in such a manner at the lateral boundaryofthesubstructure3thattheyallowthe door 7 to be pivoted outto completely free the door opening 9 even when the paper deposit surfaces 4 are tilted up. The door is thus pivotable out at least as far as the position denoted by the chain-dotted arrow line Sin Figure 2, sothatthe sackorcontainer6can be conveniently pulled out forwardly, thus out through the opening 9.

The door7 includes a rearward recess or pocket 7a, which corresponds to the width b of the paper deposit flaps 4 and which projects into the interior of the substructure 3 when the door 7 is closed. The recess corresponds to about 1/3 of the depth ofthe flaps 4 and projects into these by about the same amount in the tilted-out state of the flaps (denoted by 4'). Figure 3 illustrates this to an enlarged scale compared with Figures 1 and 2 and in addition shows the mounting of the flaps 4 in the metal side members of the rearward recess 7a by means of an elongate hole 11 and a pin 12. The recess 7a can be bounded towards the interior space ofthe substructure 3 by a rearwall 5a with abutments 4a for holding the tilted-out flaps 4.The width B ofthe opening 9 of the substructure 3 is greater at both sides by a small amount a than the width b' ofthe recess 7a, which receives the flaps 4, of the door 7.
