W. LEN NARTZ ASSEMBLY FOLDER July 30, 196,3
Filed April 1, 1959 INVENTOR. BYNHL /V/VZ United States Patent C 3,099,463 ASSEMBLY FOLDER Walter Lennartz, Krautergarten, Dachau-ost, Germany Filed Apr. 1, 1959, Ser. No. 803,520 Claims priority, application Germany Apr. 3, 1958 3 Claims. (Cl. 28119) Assembly folders of synthetic material for storing cases made of synthetic material or for showing of so-called prospectus cases made of transparent soft foil are known; these folders have many different kinds of devices for filing, which devices are made entirely of metal in the form of screw springs, wire bows, etc. and which need fittings, again of metal and composed of several parts, for the connection to the fold-er.
Many and real disadvantages arise for the assembly folders through these metal holding devices.
First of all such filing devices demand a comparatively great amount of space, in height and in width, so that such folders have to have a wide, unhandy back which for the most part is not fuliy utilized and which absolutely is not necessary. The closed and only partly lled folder then forms a long wedge which makes it impossible to stack many folders. In addition, the folder takes up correspondingly more space on a shelf, etc. Moreover, the single assembly folders are already somewhat bulky due to the broader back necessary for the fittings, etc. so that there is not, or not sufficient, room left in a dispatch case for other articles or these must be pressed together in a disadvantageous manner. Furthermore these metal holding devices increase the weight of the folder and it is not only -the metal itself but also the thick-walled, stili folder cover, necessary for fastening the fittings, which contribute to the weight. If the folder consists of thin Walls and flexible parts as for example in `a paper folder, then only filing tongues can be used, not devices of the mentioned type.
Furthermore assembly folders of the letter file type are known which have a tiling device placed ion a track on the inside of the folder back and which track can be inserted and removed.
The invention relates to lan assembly folder of synthetic material especially for cases made of synthetic material which produces a new type of assembly folder, an intermediate type between the stiff folder and the paper folder and which avoids the drawbacks of these two types.
The invention consists therein that an inside strip arranged on the folder back has a bent-in fold on its free edge which, together with the turning fold of the inside strip, compose the guide for the track.
This design has a number of advantages.
First of all, the assembly folder remains at because there are no tiling members and thus the wide back also must be used since the flat inside strip is used as a guide and the stack of cases iiled on the track lies between said track and the rear folder cover. The reduced weight of the assembly folder is also important; this is accomplished through the light weight execution of the folder as well as by not using any metal parts. The dependable and permanent embedding of the case stack -by means of rthe track is especially to be noted; this is enclosed by the inside strip so that a loosening of this binding or an independent loosening or falling out of the track with its led stack of cases is impossible, whereby it makes no difference whether the assembly folder is kept in a standing or hanging position. Finally the simple method of use is important: the track, iilled with the stack of cases is inserted into the inside strip from one end of the same, either from the bottom for from the top, or conversely, removed, in order to be able to exchange the cases on the track in the usual manner.
The following embodiments show the object of the invention:
FIG. 1 is a perspective view,
FIG. 2 is a front elevation, enlarged,
FIG. 3 is a view lfrom above, and
FIG. 4 shows a detail.
The assembly folder consists of the rear cover 1 and the front cover 2 which are of hard foil and of conventional synthetic material.
The inside narrow and elongated strip 3 is arranged on the folder back and is made yadvantageously of one piece with the rear folder cover 1, which, according to the invention, is shaped to form the guide for the track 4, which serves to carry the stack of Ithe filed cases.
This guide is, compare FIG. 2, formed by an inwardly bent fold or lip 6 on the free edge of the inside strip 3 and by the turning fold 7 of the strip 3, so that a U-shaped setting is formed which holds the track 4 securely and in spite of this makes it possible to insert or remove the track easily.
It is possible to provide a second fold independent of this on the inside of the fold 7, which can be made in one piece with the inside strip 3; also the fold or lip 6 (or in some cases both folds) can run somewhat bent against the strip 3 whereby the fold receives a certain amount of spring which increases the clasping ability without any disadvantageous inuences lon the changeability.
The track 4 is provided with :a holding device for the cases 5 to be filed, which holding device can in general be shaped in different ways. In most cases the usual flexible filing tongues S are sufficient; they are shown as dotted lines in FIG. 3. These 'tongues have the advantage that they lie flat on the track 4 again so that the filed cases 5 and the bent over tongues can be inserted into or removed from the U-shaped inside strip S without any diiculty. The filed case stack 5 on the track 4 makes it easier to introduce and to remove the track 4 into, respectively, out of, the U-shaped inside strip 3, in that the stack 5 for example is held directly next to the track with the thumb and rst finger 'and then, while introducing the track is either pulled upward, or, when being removed, pulled downward, so that only one movement is necessary to lay the track 4 free so that the cases can be exchanged.
In order to insert the track 4 into the U-shaped inside strip 3 it is appropriate to cover the holding device, i.e. the ling tongues or prongs 8, or some other equipment arranged for this purpose, with an yauxiliary strip 9, see FIG. 4. This auxiliary strip can also be made of synthetic foil whose upper half is connected, either glued or welded, with the track 4 and whose lower half loosely covers the filing tongues 8 so that these can be laid free when they are to be used.
The attention is also drawn to the tfact that there is taken a special measure which serves to increase the holding capacity considerably. It is advantageous iwhen the cases `5 are executed with a simple foil appendage .10 arranged on the filing end and which is equipped with perforations. The appendage consists thus of a simple thin foil so that even when 30 or more cases are stacked there is still a comparatively thin package which can be easily put between the inner strip 3 and the rear cover 1 Without too much expansion of the folder taking place.
The rear cover 1 is connected advantageously with the front cover 2 by a back strip 11 composed of soft foil. lt must be said, however, that the execution of the assembly folder as such can be formed as wished, ie. so
that the rear cover 1 with the front cover 2, together with the back strip 11 and the inside strip 3 all consist of one piece of foil, whereby the inside strip 3` for exa ample is `formed by a rfold. In the salme manner the foil for the rear as yWell as for the front cover can be chosen as to the type of synthetic material, as to strength or as to transparency or opaqneness.
I claim:
