Door for a shredder

The invention relates to a door for a shredder, for closing an interior thereof, which is provided within a housing and below a cutting mechanism of the shredder for receiving a collecting container for the shredded material.

Document shredders for the comminution of data carrier material in the form of sheet-shaped documents, CDs, microfilms, floppy disks and the like materials are known in a wide variety of designs and performance classes.

Paper shredders of the lower performance class usually have a collection container, often called trash or drip tray, which closes in the inserted state at the same time the receiving opening in the shredder's housing such that no reaching in to the cutting unit or parts of the cutting unit can be done. These collectors also interact with safety switches, the Prevent starting up of the cutting unit when the collecting container is removed.

The two narrow end faces of the side walls of the shredder housing and the front surface of the catch tray form the front face of the shredder.

In shredders of the middle and upper power class, the housing according to the forces occurring as well as due to the size of the cutting units designed to be much more stable than at

Shredding the lower performance class. These housings are usually made of wood.

The removal opening for inserting and removing the collecting container, this may be a collecting container or a mounted on a frame collecting bag or collecting bag is closed with a door. To remove the collection container or a collection bag, the door is opened, whereby a reaching in to the cutting would be possible. When opening the door, a safety switch is simultaneously activated, which prevents operation of the shredder.

These doors are usually also made of wood, mainly from pressboard and the like material. So that the work result as well as the level of the collecting container can be observed during operation of the shredder, a viewing window is provided in the doors.

In addition to the impact and shock susceptibility of such wooden or

Wood composites existing doors in addition to the cost of non-harmful adhesives and adhesives, the mass of such doors is disadvantageous, especially for handling in the manufacture and assembly and for the transport weight, so the transport costs.

Therefore, the object of the invention is to develop a door for a document shredder, which is inexpensive both in terms of material and manufacturing costs and the transport costs and also has a high stability.

For the purposes of the present invention, document shredder means a device for comminuting data carrier material, which may be sheet-form documents, compact discs, microfilms, floppy disks and similar materials.

The object is achieved by a door for a shredder with the features of claim 1. The subordinate claims 2 to 13 show developments and advantageous embodiments of the invention. The inventive door for a shredder, closing at least one open on one side, provided below a cutting unit in the housing of the shredder or the like device interior, preferably has a window and hinges for attachment to the housing and is in a new design of two

Profile parts assembled, preferably from an outer door leaf and an inner door leaf. Both parts of the door are non-positively and / or positively connected with each other.

Profile parts in the sense of the invention are parts in which, starting from the plane of their main surface, one or more partial surfaces, surface sections or surface strips of the main surface are arranged at an angle to the latter, wherein these regions which are fleeing from the main plane are angled one or more times or arcuately guided , in one or in succession in several spatial directions, which may also be in opposite directions.

These profile parts are preferably manufactured as injection-molded parts and preferably made of plastic.

The interior serves to receive a collecting container, in which the crushed material emerging from the cutting mechanism is collected.

By correspondingly arranged to each other arranged portions of the two door leaves results in the assembled state of Advantage that the body of the door is a very stable in itself unit, especially at the top, at the point of force attack when opening and closing the door.

The connection between the two door parts is made by screwing, gluing or welding, preferably the frictional connection between the two parts of the door is punctual. The advantage of a screw connection is that in addition to a positive connection still one, the rigidity of the door increasing, non-positive, but releasable connection can be achieved.

The two door leaves are preferably made of plastic, so that the door has a low weight.

In a special new design, the outer door leaf has a profiled, substantially 90 ° from a front surface of the same angled edge, said profiled edge is encircling on three sides of the door leaf, preferably at its left, top and right section. In the outer door leaf is directed from the lower portion of the body inward, preferably symmetrical to the imaginary vertical plane of symmetry, a conical, preferably arched or trapezoidal recess provided, which preferably extends up into the upper region of the outer door leaf and passes through the front surface and the opposite surface. This recess has laterally rising longitudinal limbs that end up in an upper transverse leg. The longitudinal legs of the conical, preferably arched recess preferably have a U-shaped profiled edge. The inner door leaf has a profiled edge substantially angled 90 ° from an outer surface thereof, this profiled edge being encircling on three sides of the inner door leaf, preferably also on its left, upper and right sections. Corresponding to the conical, preferably arched or trapezoidal recess in the outer door leaf is arranged in the inner door leaf, starting from the outer surface, a door inwardly directed indentation. The front edges on the indentation have profiled webs which are formed corresponding to the U-shaped profiled edges of the longitudinal limbs, resulting in a further stiffening / stability of the door.

In addition, further recesses or bulges are provided in the outer surface of the inner door leaf, in which preferably accessories for the shredder, such as maintenance oil, collection bag u. Ä., Can be accommodated.

At least one of the profile parts, preferably the inner door leaf, in particular its recess, consists of at least translucent, preferably made of transparent material, whereby always have a look inside the document shredder and at the shredded material.

The above-described redesigned door results in significant advantages for the logistics as well as in terms of costs for production (production, assembly, surface treatment), warehousing and transport, together with the required transport volume, to the wholesaler, retailer or end user.

The invention will be explained below with reference to an embodiment schematically shown in the drawings and in detail. Showing:

Shredder to which the new door is malleable.

An embodiment of the new, composed of two moldings door 1 is shown in Figure 3 with a front view of the inner outer surface 12 and in Figure 3d in a perspective view of this. In Figure 3a, the door 1 is shown in side view and in Figure 3b in plan view. The two mold parts, the outer door leaf 2 and the inner door leaf 10, have various projections, bends, recesses, grooves or slots and webs. These are arranged on both parts 2, 10 corresponding to each other so that in the assembled state, the aforementioned portions of the two door leaves 2 and 10 give a support structure, so that the body of the door 1 is a very stable in itself unit, especially in the upper area, at the force attack point when opening and closing the door.

The outer 2 and the inner 10 door leaf are preferably made of plastic, so that the door is very light. Preferably, the inner door leaf 10, in particular in its central region, made of a translucent, preferably made of transparent material.

In addition, the design of the outer door leaf 2 of this embodiment will be explained in more detail first with reference to Figures 1 a and 1 b. The outer Door leaf 2 is a substantially rectangular shaped body. The outer edge is angled in the region of the left portion 3c, the upper portion 3a and the right portion 3b directed from a body base by 90 ° inwards. This edge runs circumferentially from the lower edge of the left portion 3c over the upper portion down to the lower edge of the right portion 3b. The above-mentioned directions left, right and above arise by looking at the front surface of a document shredder, on which such a door is arranged.

The lower portion 3d of the outer edge 3 has no angulation. This lower section 3d is, symmetrically, provided from below with an arch-shaped recess 5, which preferably extends up into the upper region of the outer door leaf 2. This arched recess 5 is respectively formed on the left and right by a longitudinal leg 5a, which is directed upwardly sideways, and is bounded by an upper transverse leg 5b in the vertical extension. The longitudinal legs 5a extend, in this embodiment, slightly arcuate. The front edge 5 c of the longitudinal leg 5 a has a U-shaped shape, wherein the open side of the "U" respectively in the direction of the outer edge of the outer door leaf 2 shows. In this provided in each longitudinal leg 5a groove engages a corresponding opposite of the inner door leaf 10, as will be described later. With a little distance from the longitudinal legs 5a and the upper transverse leg 5b and the edges 5c extends slightly in the body slightly recessed an inner peripheral edge 6, which protrudes from the inner side 8 of the outer front surface 4 approximately at right angles. Between the inner circumferential edge 6 and the outer circumferential edge 3 a plurality of substantially transversely and / or obliquely arranged webs 7 are provided for further stiffening of the door first

In Figures 2a and 2b, the inner door leaf 10 is shown in frontal view and perspective view. The base of this inner door leaf 10 is a substantially rectangular thin plate with an outer surface 12. This outer surface 12 shows in its position of use to the interior 20 of the shredder 18 and abuts the end faces 24 of the housing 19 of the shredder 18, see also in FIG. 4.

The inner door leaf 10 has a likewise in the upper, right and left sections 1 1 a, 1 1 b and 1 1 c circumferential edge 1 1, which is directed from the outer surface 12 with a bend, preferably by 90 °, towards the body. The lower portion 1 1 d of the rim 1 1 does not have such a bend. At the upper portion 1 1 a of the edge 1 1 also in the plane of the outer surface 12 upwardly projecting web 12a is provided; which rests in the assembled state of the door at the upper portion 3 a of the edge 3 of the outer door leaf 2. Likewise, in the assembled state of the door, respectively upper portions 3a, 1 1 a, the right sections 3b, 1 1 b, and the left sections 3c, 1 1 c to form fit. These edge portions are at least partially positively connected to each other, by latching, gluing or welding. Corresponding to the arch-shaped recess 5 in the outer door leaf 2, a correspondingly extending indentation 14 is provided on the inner door leaf 10 symmetrically to its plane of symmetry. In the assembled state of the door, this indentation 14 forms a niche 14a in the body of the door 1.

Corresponding to the course of the longitudinal limbs 5a of the arched recess 5, front edges 16 are provided on the indentation 14. These edges 16 have corresponding to the U-shaped profile edges 5c of the outer door leaf 2 a hook-shaped edge profile. When mounting the door, the outer door leaf 2 and the inner door leaf 10 are inserted into one another by relative movement to each other, wherein the profiled edge 16 hooks in the profiled edge 5c and runs along this until the final assembly position is reached. To further increase the stability of the indentation 14 is formed so that a three-sided circumferential support surface 15 is formed. This support surface 15 is in the assembled state of the door on the inner circumferential edge 6 of the arched recess 5 a form-fitting manner. As mentioned above, the completely assembled door 1 is shown in a frontal view from the inside in FIG. In the outer surface 12 of the inner door leaf 10 also more recesses or bulges are provided in which accessories for the shredder, such as maintenance oil, collection bag, etc., can be accommodated.

At least the front surface of the indentation 14, but preferably the entire inner door leaf 10 are made of an at least translucent, preferably transparent material, in particular plastic, so that always a look in the interior 20 and on the crushed material can be addressed. In FIG. 3a, the fully assembled door is shown in a side view from the right. In the figure 3b in plan view with respect to the illustration in Figure 3 in section D-D. Here, the position of the outer surface 12 and the front surface 4 and the position of the niche formed by the recess 14 14a in the door 1 can be seen.

The positioning of the edge regions 3a, 11a and 12a of the outer door leaf 2 and of the inner door leaf 10 relative to one another are shown in sectional view in FIG. 3, the detail "B" according to FIG. 3a.

In the figure 3g is the detail "F" from the illustration of Figure 3b, the special profiled design of the edge 5c of the longitudinal leg 5a of the arched recess 5 and the special profiled design of the front edge 16 of the inner Door leaf 10 shown in detail. In addition, the positive engagement of the inner circumferential edge 6 of the outer door leaf 2 and the three-sided circumferential support surface 15 of the inner door leaf 10 can be seen in this illustration.

Further details of the positive engagement of the profiled sections of the outer door leaf 2 and the inner door leaf 10 are also shown in the details "E" of Figure 3b and detail "C" of Figure 3a in Figures 3f and 3e. In FIG. 3f, the positive connection of the lateral edges 3b of the outer door leaf with the right angled section 11b of the inner door leaf 10, which forms a bend on its outer surface 12, can be seen. In the figure 3e is shown in sectional view and detailed view of the lower portion of the door according to detail "C" of Figure 3a. The lower portion 3d of the outer door leaf 2 forms the conclusion of

Front surface 4 of the outer door leaf 2, without bending. In addition, the position of webs 7 with respect to the inside 13 of the outer surface 12 of the inner door leaf 10 can still be seen in this illustration.

In order to achieve, in addition to a form-fitting connection, a non-positive but releasable connection which increases the rigidity of the door, screw connections are provided on the points marked on the outer surface 12 in FIGS. 3 and 3d (without reference symbols). A higher rigidity of the assembled door can also be achieved that at certain points or over larger surface portions, the form-fitting abutting surfaces of the outer door leaf 2 and the inner door leaf 10 are glued together or welded together.

FIG. 4 schematically shows a document shredder to which the new door described above has been applied. A document shredder 18 with a housing 19 has an interior space 20, in which a collection bag 21 for receiving shredded material is arranged on a holder 23 mounted in guides 23. A door 1 according to the invention is fixed with hinges 25 on the housing 19 and shown here in the open position. In the closed position, the door 1 with its outer surface 12 of the inner door leaf 10 together with the outer edge 3 of the outer

Door leaf 2 rest against one or more end faces 24 of the housing 19 and close the interior 20, so that the shredder without danger to the operator can be in operation. Not shown is a self-evident safety switch that will shut down the drive of the shredder when opening the door 1, so when sharing the interior 20 together with access to the cutting unit. The material / paper task has the reference number 26. The invention is not limited to the embodiment shown, but in the context of the invention often variable. In particular, in the choice of material for the production of the outer door leaf 2 and the inner door leaf 10 and in the design of contour and design, there are no limits. The choice of suitable material will be able to be oriented and adapted to the task of the shredder concerned or to the development of new materials in the relevant field.

Thus, in the figure 3b with the reference numerals 9a and 9b shown that, for example, in the upper region of the outer door leaf 2, the edge portion of the outer upper edge 3a has a horizontally directed convex curvature 9a and a body-facing concave curvature 9b. This ensures that the distance between the door and operator with respect to the upper door area in

Is larger footing so that the operator can get closer to the insertion slot or the material support without the operator with his feet damaged the lower door area or leaning against the paper feed, resulting in a worn by the operator / operator tie, chain or z.
