Magazine device, in particular for microfilms

The invention relates generally to filing facilities and in particular those placed in compartments for storing thin sheet-like objects such as microfilm or by film negatives. In connection with the increased use of photomicrographs for information storage, Keeping records etc. is a necessity suitable magazine devices for such films emerged. Films are usually in pockets or compartments different designs depending on the type and size of the negatives kept. These pockets or compartments are often arranged on larger sheets in suitable containers or folders be stored.

A commonly "known problem associated with storage devices and archives is that the available space is filled very quickly due to the larger amounts of material. There is therefore always the need to develop new and small-space magazine devices to reduce the space required by the latter in relation to the stored material.

The invention is based on the object for a simple and practical solution to this problem by creating a novel combined storage bag with compartments that are suitable for insertion into a cover. The essential to the invention Features for solving this problem emerge from the attached patent claims.

Further details and advantages of the invention result from the description of the drawing, in which the principle of the invention is illustrated using an exemplary embodiment. In the Drawing are;

Figure 1 shows the principle of a sheet forming the basis for a combined magazine device,

Figure 2 shows the principle of a cover sheet over which the Base forming arch is arranged according to Figure 1 and attached according to predetermined principles, and

Figure 3 shows the connection of the two arches, with the joints are marked in between and show the principle of chaining.

Figure 1 shows the outlines of an arch forming the basis, which in the present case is made of a fairly stiff PVC material. The arch has two parallel rows

of slots made with the help of a suitable cutting tool. have been made, and their edges one-on-the-head Form a standing V. By moving the tool relative to rows of even slots are obtained in the arch. Within of these rows, the material is thus in closely interlinked strips, each forming an upside-down T, chained. These strips are connected at the lower ends to the arch that forms the basis and become the main parts the compartments form when the top part - the V-shaped strip bent out of the plane of the foundation.

As mentioned above, this way there are so many subjects generated from the material forming the basis, as there are intersections therein which are a considerable number of usable Fan with a fairly narrow cut density should be emphasized that this according to the invention by only one Layer of a base material is achieved at each point, thus ensuring a minimum of thickness. The punched V-shaped strip parts are identified in FIG. 1 with the reference symbol "1".

However, the basic material alone does not create any fully functioning unit, but rather must be completed by a cover layer according to FIG. Of the Cover sheet has the same dimensions as the base and is provided with linear, horizontal intersections, their Length and distance from one another are chosen such that a number Strips are generated which, when the sheets forming the base and the cover are joined, each cover a pair of strip tips in the base material. The stripes of the Cover sheets and the tips of the strips of the base Arches are then spot welded together, creating complete storage compartments, their upper limit marked by the horizontal stripes on the cover sheet. Vertical welds limit the width

the fan, and the cover strips are in Figure 2 with the Reference number "2".

The description is intended only to illustrate the principle of construction of the proposed Expose storage unit. In practice it is advantageous to use material of double width, whereby it is through double folding is possible, a storage unit with compartments both on the front and on the back. This unit can be with a stiffener and with an average be provided on the long side. The other long side can be provided with a hanger for grouping the sheets.

Figure 3 shows the connection of the base and the cover forming arc, with the reference number "5" denoting the welding points. Figure 3 shows the tip-shaped parts of the sheet forming the basis and the strips of the cover sheet in relation to each other.

The invention is in the description in its generality and a practical embodiment has been given. The details regarding the choice of dimensions, of the material and finishing for special purposes however, can be varied in the most varied of ways without departing from the scope of the invention. Regarding the choice of material It should be emphasized that in connection with the application of the invention to the storage of films it is important that the material does not adversely affect the film. For this reason, a stiff PVG material is used in this context a low percentage of plasticizers, which protects the film used against migration of plastic. However, this aspect is not relevant to the essence of the invention.
