Description

FOLDER FOR STORING PAPER SHEETS

The invention relates to a device for storing sheets of paper, files or filing pockets, such as file folders, document pockets or block folders, according to the preamble of claim 1.

In conventional, generic folders, the line-up device, such as a bracket mechanism, is firmly connected to a wall part. Such folders also take up a lot of space when empty. The fact that the entire, in itself organized file content cannot simply be transferred independently of the part carrying the line-up device - which would be desirable, for example, in the case of unsightly or possibly too small folders - is to be regarded as just as disadvantageous as the inconvenience of not being able to remove "dead" or out-of-date file bursts as such from the folder, storing them and, if necessary, integrating them into the same or a different folder when reactivated.

Various proposals have been made to design file folders in such a way that they meet these requirements.

For example, EP-A1 482 354 shows a folder which consists of three parts, namely the actual folder with its wall, back and lid parts, the line-up device for receiving the paper or documents to be stored with a base plate, and from a mounting plate. The mounting plate and base plate are arranged on different sides of the file folder in the assembled state, the mounting plate reaching through corresponding recesses in the wall part of the file folder. In the system disclosed in EP-A2-185 634, the line-up mechanism is attached to the file via two Velcro strips, which are provided on the one hand on the inside of the file and on the other hand on the line-up mechanism, can be lifted off and, if necessary, another file can be inserted.

In the file folder according to DE-A1 30 13 310, the line-up device is held on the file cover by means of catches and holders provided on the latter. To release the line-up device, the catches must be released, only then can the line-up device be rotated and pulled out of the holders.

These systems are certainly functional in themselves, but each has certain disadvantages. For example, in the mechanism described in EP-A1 482 354 it is necessary that three parts which are separate per se have to be manufactured in a precisely fitting manner, the recesses in the file folder, through which the elements provided for fastening the base plate extend, having an identical shape and must be manufactured essentially without play. These exceptions, on which a not inconsiderable weight is drawn in the case of filled file folders standing on a shelf, must also be made as strong as possible.

The system described in EP-A2-185 634 is essentially only suitable for depositing and depositing relatively thin paper stacks, since Velcro tapes have a reduced adhesive force after being loosened and reassembled several times.

In the case of the file folder described in DE-A1 30 13 310, in turn, several parts of different modes of action play together, neither the insertion nor the releasing of the line-up device is possible with one hand; Rotary-sliding movement can be carried out. Behind it is the idea to prevent the unwanted removal of a stack of files from the folder.

However, none of these systems corresponds to a concept that takes ecological aspects into consideration, in particular that of disposal and recycling.

An alternative system that takes this aspect into account has become known from WO 93/24335. The plate carrying the ring mechanism or the file spine here have elastic snap-in projections which come into engagement with corresponding recesses in the file spine or in the plate. If these latching projections are provided on the plate, they will be made of the same material as the plate, i.e. generally made of metal. These snap-in projections engage in recesses on the back of the folder and, because they protrude from the surface of the folder, can be perceived as annoying when the folder is used, or scratch surfaces on which the folder is placed or even lead to injuries if handled carelessly. Elastic snap-in projections, which are provided on the inside of the folder and are formed, for example, from plastic, tend to break after repeated use, which is exacerbated by the possibly high load when the folder is full.

In contrast, the invention has set itself the task of providing a device for storing paper sheets and the like, which can be disposed of simply and in an ecologically sensible manner, which, compared to the known systems, allows simple and safe handling when inserting and releasing the aligning device, at the same time being stable, Fatigue-free fastening of thick and heavy stacks of files is also possible and is also interesting in terms of production technology. This is achieved surprisingly by the

Realization of the characteristic features of claim 1. In view of the known attempts to solve the problem, the training according to the invention is astounding and surprisingly simple.

In the following, "one-piece" is to be understood to mean the same material free of, for example, reinforcing foreign material, in order to be able to dispose of unused files without problems.

If an opposing part is provided, a line-up device introduced is securely fixed, as a result of which heavy and thick file collisions in particular are securely held. Such a counterpart could be designed in a manner known per se as a profile which overlaps, possibly slightly resiliently, over the holding strips provided on the holder of the line-up device, but both the insertion and the loosening of the line-up device are simplified if this counterpart is wedge-shaped, with in Insertion direction of the slope is formed.

Advantageous further developments are described in the features of the dependent claims.

The rails formed in one piece with the wall part can be designed both as grooves milled into the wall part. However, since file folders with relatively thick walls are of interest to very few users for reasons of handling alone, such grooves that weaken the folder will seldom be considered. For this reason, rails in the form of guides that cross the retaining strips will be preferred.

So that the holder of the aligning device can be held on its holding strips within the guides on the one hand in a clamped position and on the other hand the insertion or detachment of the holder into or from the guides can be done without great effort, they are perpendicular to the In the direction of insertion arranged inner surfaces of the guides are preferably uneven, for example wavy or provided with knobs. On the one hand, this makes the desired clamping fit possible and, on the other hand, the holder can move more easily due to the reduced friction.

As in known folders, the line-up device, which can be, for example, a bracket or clamp mechanism, will consist of metal or largely of metal. That for wall part, ceiling and back part or the associated

Parts, such as rails, stop and counterpart, provided material, however, is preferably plastic, in particular a polymerization product of short alkenes. This includes, for example, polyethylene, which in itself is not uninteresting from an economic point of view, but which can only be used as a folder material to a limited extent, since it is somewhat too soft. In the case of a folder made of polyethylene filled with a thicker stack of files, the edges would bend or wave over time, the holder of the aligning device would not be seated sufficiently firmly in the rails.

An alkene which is particularly suitable for a folder according to the invention, on the other hand, is isotactic polypropylene, which is distinguished by great strength and at the same time good elastic properties. The use of this material results in the possibility of one-piece training, particularly for a file order, the wall, back and lid parts of which are connected to one another via articulated grooves which are exposed to not inconsiderable stress. Known file blankets, on the other hand, essentially consist of cardboard, which can be laminated with plastic, and which is reinforced with metal edges to increase the lifespan at corners, engagement recesses and slots with ratchet cams for engaging the bracket. Such a conventional folder therefore consists of two to three different, interconnected materials and cannot be disposed of in an ecologically sensible manner. Bending tests in which a file folder according to the invention, the wall, back and lid parts of which is made of isotactic polypropylene, were opened and closed up to 100,000 times, did not result in any fatigue cracks in the articulated grooves. Normal polypropylene as such would also be conceivable as a material; however, it has the disadvantage that at lower temperatures - below 0 ° C - it tends to break, particularly at the joint grooves.

Alternatively, isotactically linked, other short alkenes could also be used.

It is precisely the use of such an advantageous material as the isotactic polypropylene that opens up further possibilities for the advantageous design of a file folder according to the invention. Thus, the wall, back and / or cover part can be provided with openings, which - regardless of an aesthetic effect that may be achieved - give the possibility of saving material on the one hand, thus keeping the folder easier at the same time, and on the other hand providing insight allow the contents of the folder.

The total area of the openings must be dimensioned so that the corresponding parts are not weakened. For example, for file folder wall or cover parts, it should be a maximum of 25% of the wall or cover areas.

It goes without saying that copolymers with corresponding proportions of polyethylene, polypropylene or polybutylene can also be used as materials.

The invention is described below by way of example with reference to drawings. Show it 1 shows a diagrammatic partial view of a file folder according to the invention with inserted filing device;

2 shows a plan view of the part of the file folder which has the parts provided for receiving a line-up device in accordance with FIG

3a and 3b two sections along A-A and B-B of Fig.2

1 shows part of an open file folder, with a wall part 1, a back part 2 and a cover part 3, which are formed in one piece and connected to one another via articulated grooves 13.

A tearing device 4 designed as a bracket mechanism is fixed on the wall part 1. Bracket 6 and tilt mechanism 14 are arranged on a base plate serving as a holder 5. Holding strips 5a, which are parallel to each other on this holder 5, are overlapped by guide rails 7. These rails 7 are integrally connected to the wall part 1. Crosspieces 15 support against the wall part 1 and serve in particular to increase the stability of the guide rails 7. A stop 8 designed in accordance with the edge shape of the holder limits the insertion path when inserting the reaming device 4 into the rails 7. The insertion direction is represented by arrow 10. The stop 8 is also formed in one piece with the wall part 1 and also overlaps with an angled upper edge section the limitation of the holder 5 serving as a holding strip 5b.

Openings 12 in wall and cover parts 1 and 3 can be provided as a search aid and at the same time can be designed according to a current sense of shape. 2 and the two associated sections AA and BB, which are shown in FIGS. 3a and 3b, show the design of the parts of the folder provided for accommodating an opening device.

The rails 7 with their upper, angled edge part 7a have a curved web at one end, which serves as an insertion aid 16 for the reaming device. The stop 8 adjacent to the other end of the rails 7, due to its angled edge with which the retaining strip 5b is overlapped and fixed, acts not only as a stop in this embodiment, but also, like the rails 7, also as a restraint. This design is particularly advantageous for accommodating ironing mechanisms, which may contain heavy and / or voluminous stacks, and which therefore cannot fall out even when the folder is handled more carelessly.

However, it is also possible to provide a stop at the end of the rails 7, for example by forming them closed at one end.

As an additional precaution against unintentional loosening of the line-up device, a counterpart 9 will advantageously be provided, which is also formed in one piece with the wall part 1 and which, when the line-up device 4 (FIG. 1) is fully inserted, the holder 5 (in 3b indicated by dashed lines) with its end face 17. To release the reaming device 4, it only has to be raised slightly above this end face 17 so that it can then be pulled out of the rails 7.

As can be seen from Figure 2a, the inner surface 11 of the rail 7 is not designed as a flat surface. As indicated by the dashed line, it protrudes to different extents, in particular is wave-shaped, as a result of which the insertion and removal of the reaming device from the guide rails NEN 7 is facilitated. Nevertheless, a sufficiently good clamping fit of the holder 5 of the reaming device 4 (FIG. 1) is ensured.
