Description

Loose-leaf binders with at least two flexible ones across the binding edge of the Documents that can be folded back in rows The invention relates to a loose-leaf binder for punched documents, with at least one line-up device of two across Elastic, flexible opening tabs that can be folded over to the binding edge of the written material Plastic formed on at least one of folding legs or folding strips that Inside fold connecting the cover lid. This well-known flat file still has for each line-up device - one to the side of the growing pile of documents extending device for Aufnalltne the foldable ends of the respectively associated Pair of lined up tongues, on the side of which the corresponding cover lid in the area of the inner fold is provided with longitudinally running fold grooves so that its back is located can adapt to a growing pile of documents.

The two openings made of metal, whalebone, celluloid or the like such a folder are formed by a piece of tape, the middle part corresponding to the spacing of the rows between the fold legs of the inner fold runs and is fixed in this. However, the middle section is predominantly interspersed some slots punched in both fold legs or fold strips of the inner fold. The fastening or threading through the slots is made by means of special Machines designed for the production of loose-leaf binders in the usual format are built. Such machines are expensive and only economical if their full capacity can be used. Also come for the flat file production Machines are used, by means of which the loose-leaf binders with the usual format of the roll can be manufactured ready for sale.

The device for receiving documents from a lined up stack of documents protruding and freely terminating ends of a pair of lined up tongues is supported by a made of cardboard parallel to the inner fold, which is placed on the inside of the The envelope cover is attached, e.g. by gluing, to the side of which the stack of documents is attached grows. Channel-like guides are pressed out of this strip, which in The direction of the lines that can be folded over to the binding edge of the documents run. Narrow bridge-like eyelets can also be arranged at the point of the strip, in which the ends of the rows in the same way as in the guides of the Be inserted into the strip. Both- in the guides of the strip and in the bridge-like eyelets, the rows are guided with great play, see above that they are freely displaceable in their longitudinal direction.

Such a loose-leaf binder has the advantage that when the cover is open, the documents can be turned over in a book-like manner on the tabs running across the back of the loose-leaf binder. When the envelope lid provided with the device is closed or opened, the strings adapt to the movement of the envelope lid, i. That is, the part of the lined-up tongues running between the lined-up stack of documents and the strip or the bridge-like eyelets is shortened or lengthened automatically depending on the movement of the envelope cover, with the ends of the lined-up tongues either pushed further into the guides or eyelets or partially again be pulled out. Their elasticity prevents the strings from kinking or bending.

However, it has been found that when handling a more or less filled loose-leaf binder, the lined up stack of documents hangs out or emerges between the closed envelope covers, so that the edges of the documents can be bent over, torn or soiled. The cause of this undesirable phenomenon is the relatively large play of the lined-up lines in the guides and an unguided part of the lined-up lines remaining between the stack of documents and the guides. Apart from this must furthermore be provided another special Umheftgabel to a desired document: by switching off lift the overlying partial stack expose and be able to remove. Such a Umheftgabel is also necessary in order to be able to re-staple the completed stack of documents of a loose-leaf binder for the old file in an intermediate stapler, on a flap provided with a liner or the like, especially when the loose-leaf binder z. B. consists of plastic and should be re-used due to its long service life. However, a filing fork is a loose piece that can be easily misplaced.

The previously known loose-leaf binders therefore do not guarantee sufficient information Protection for the lined up documents, which is expensive to manufacture, only requires itself Machines that are worthwhile for large editions as well as one that is not effective Coming material expenditure for the middle part holding the lined up and makes awkward handling is necessary for the old filing of documents. Despite The known loose-leaf binders are therefore proportionate to the advantages described above uneconomical. This inefficiency becomes even greater when the fast stapler Used in smaller quantities with a format deviating from the usual size that cannot be produced on the existing machines, so that some Operations must be carried out by hand.

It is therefore the object of the invention to provide the loose-leaf binders according to the genre explained at the beginning so that the lined up documents in any position that can be produced economically, even with a different format size Do not change the position of the loose-leaf binder in relation to the inner fold and if necessary can also be removed as a closed stack of documents.

This object is achieved according to the invention in that the free end of each line-up tongue with the loose-leaf binder closed is held displaceably by the device under friction from its fastening point on the inner fold at a distance of the respective thickness of the stack of documents in a row, and each line-up tongue on the other , the end serving for fastening has at least two opposing notches and the possibly interchangeable folding strip receiving the lined-up tongues each has two spaced-apart slots with a width roughly corresponding to the lined-up tongues, one of which is at a distance of the width of the binding margin of the document from the adjacent inner folded edge of the folding strip and the other slot is arranged perpendicular to the folded edge and symmetrically to the first slot, in such a way that each rowing tongue inserted into two mutually associated slots at least through two i shoulders formed by the notches are held in the vertical slot and led out of the folding strip through the other slot at a distance of the width of the binding margin from the inner folding edge.

In general, the training is carried out in such a way that each device for slidably holding the ends of a pair of aligning tongues is formed by a strip of cardboard, plastic film or the like parallel to the inner fold, with two rows of slots extending at a distance and in the direction of the aligning tongues, the slots of which have one have stood mutual, the folding grooves corresponding ider envelope cover waste and are parallel to the folding grooves, the strip is arranged on the associated cover cap or on a corresponding flap of the Innenfalzes that is closed and with a written material stack with the thickness of a Falzrillenabstandes filled loose-leaf binders, the first slot facing the inner fold of each row of slots lies approximately above the associated alignment hole of the stack of documents and is penetrated by the alignment tongue that can be moved under friction between the strip and the cover or the flap. These measures make the snow The folder with the features mentioned in the first section has been improved so that the advantages already explained are retained, so that the difficulties that have already been described are eliminated and the problem that has been raised is solved in a favorable manner.

Further features of the invention and the advantages resulting from these features are explained on the basis of exemplary embodiments. Several exemplary embodiments of the subject matter of the invention are shown in the drawing. Fig. 1 and 2 show views of two lined-up tongues each with differently designed fastening ends, Fig. 3 the top view of a folding strip with the two lined-up tongues according to Figs. 1 and 2 and with two differently shaped pairs of slots for receiving the fastening end of one of these two tapered sections .

In all of the exemplary embodiments, each stringing device is formed in front of a pair of stringing tongues. Each stringing tongue 1 consists of an elastically flexible plastic band, namely predominantly of the plastic known under the trademark "nylon", which is characterized in particular by toughness and a certain hardness. According to FIGS. 1 and 2, each stringing tongue 1 is provided at one end with a one-sided or symmetrical point 2 in order to facilitate the stringing of the prepunched writing material. At least two opposing edge-open notches 3 are arranged in the longitudinal sides at the opposite end, so that this transverse boundary edges of the notches form shoulders, which was an approximately the thickness of the respective carrier relevant parts have. depending on the type of attachment of the strings 1 in the carrier, e.g. B. in a folding strip 4, a second pair of notches 3 can also be provided, which has a predetermined distance from the first pair and is formed in the same way. Except for the short fastening, the total length of a lacing tongue 1 practically corresponds to its usable lacing length. each sequencing tongue 1 is s in the Falzstreif 4, the od example of the lock seam of a Schnellhefterinnenfalzes, by a bent edge of a Envelope-lid, a tab. like. is formed, characterized mounted so that as shown in Fig. 3 in the folding strips 4, two slots 5 and 6 or 7 and 8 was at the waste punched from each other, each forming a running transversely to the longitudinal direction of the slot 4 Falzstreifens row. From the inner folded edge 9, which z. B. od with a cover, a flap. The like. At the same time forms a folding joint, averted slot 6 or 8 has a distance from this folding edge which corresponds approximately to the margin width 10 of the perforated documents. This slot 6 or 8 is parallel (see. Fig. 3 a) or perpendicular (see. Fig. 3 b), are punched to the folded edge 9 while the slot 5 and 7 always extends in both embodiments perpendicular to the folded edge.

In the Schlitzanordnunga jedeAufreihzungel is with its attachment end in the first folded edge 9 of the adjacent S chlitz 5 so far put into it, until the shoulders of the notches 3 in the same level with the Falzstreifenflächen are. Then the row tongue 1 is rotated 90 ' about its longitudinal center line and then pushed through the slot 6 . As a result of the twisting, the aligning tongue is firmly locked in the folding strip 4 by the shoulders reaching over the longitudinal edges of the slot 5 and secured against unintentional unlocking by the second slot 6. The second slot, located at a distance of the binding margin width 10 from the inner folding edge 9 , also takes on the guiding and erecting of the aligning tongue 1. A pair of aligning tongues fastened in this way has an inclined position facing away from the binding edge of the stack of documents, which favors the lining up. Already by taking out the sequencing tongues from the folding strips 4 in the spacing of the binding margin width 10 of the inner folded edge 9, a tilt of the written material stack in the flat file is already largely prevented because the transferred on the printed matter stack Unischlagdeckel, the tab od. Like. With the most The back of the stack of documents adjacent part or edge forms a stop. In the slot arrangement b according to Fig. 3 , the fastening end is simultaneously inserted into the two Schl-itze7 and 8 of the folding strip 4 and then the rowing tongue 1 is rotated again by 90 ' so that the Alignment tongue is locked in both slots 7 and 8 by the shoulders of the notches 3 reaching over the longitudinal edges of both slots and is held immovably. The folding strip with a line-up device designed in the above manner can be, for example, the inner folder of a loose-leaf binder consisting of two cover covers 12 and 13 , both of which are connected to one another by the inner fold (see Fig. 4). The cover 12 reaching over a lined up stack of documents when closing the folder is provided in a known manner parallel to the inner folding edge 9 with mutually spaced folding grooves 14 and with the device for slidably holding the lined up tongue ends. This device is of a strip 15 z. B. formed from paperboard having a greater length than the spacing of the lining-up tongues and 1 corresponds to the means of transverse glue applications 16, for example. B. in the area of its transverse edges and its transverse center, with the cover 12 is connected. The strip 15 is also provided with folding grooves 14 and has two - in the Umlegerichtung the sequencing tongues 1 extending slot rows. The slots 17 of each row of slots each have a width approximately corresponding to the lacing tongues 1 and are arranged at a mutual distance from the folding grooves 14 and parallel to them. Furthermore, the strip 15 is attached to the cover 12 that when the loose-leaf binders are closed and a stack of documents lined up, e.g. B. with a thickness corresponding to the rebate groove spacing, the first, d. H. the slot 17 adjacent to the inner folded edge 9 of each row of slots lies on the associated alignment hole of the stack of documents. In this first slot of the two rows of slots, the rows tongues are inserted beforehand. The latter then extend between the treifen they hold-S 15 and the envelope cover 12 and are guided between these parts under friction. In a double thickness of the printed matter stack the lining-up tongues 1 in the second slot 17, each slot number is inserted, etc. This is closed flat file between the roots at the inner fold 11 and the associated slots 17 of strip 15 not unguided part of the lining-up tongues 1 exists, so that the Lined up stacks of documents in the functional context with the folded back of the cover 12 resting against the back of the stack of documents cannot sag and is lined up immovably in the loose-leaf binder. This is particularly important if the loose-leaf file is used as a hanging file. Such a line-up device with the device used to hold down the line-up tabs in a friction-locked manner is distinguished by inexpensive manufacture, and the line-up can also be drawn in by the consumer.

In the further embodiment of the subject matter of the invention according to FIGS. 5 to 7 , the device for frictionally holding down the lined-up tongues 1 is replaceable and designed as a binding fork. The loose-leaf binder according to this exemplary embodiment also consists of two cover covers 12 and 13 connected to one another by the inner fold 11 , in which, however, a flap 18 is additionally arranged on the cover 12 by means of glue applications 16. The tab 18 is about the size of the strip in Fig. 4 and is also provided with folding grooves 14, in this tab two symmetrical to the lining-up tongues 1 and in which Umlegerichtung running insertion slots 19 are arranged, which have a mutual distance which is greater than the mutual spacing of the lacing tongues is 1 . These insertion slots 19 serve to interchangeably accommodate a strip 20 serving as a device for holding down the rows of tongues, which, in the same way as the strip 15 of the previous embodiments, has two rows of slots spaced apart from the rows of tongues 1 , the slots 17 of which are parallel to the folding grooves 14. The insertion slots 19 for the strip 20 are of course arranged in such a way that when the loose-leaf binders are closed, the slots 17 assigned to the respective thickness of the stack of documents 21 lie on the perforations 22 thereof.

The strip 20 is formed by a thin and flexible plastic film and is advantageously provided with two lifting tongues 23 , which are needle-shaped, on one longitudinal side at a mutual distance between the lacing tongues 1. To lift off a partial stack over a desired document, the lifting tongues 23 next to the lined-up tongues 1 and at an angle to the sheet surfaces of the stack of documents 21 are inserted through the lined-up holes 22 of the previously slightly raised partial stack so that their ends protrude beyond the binding edge in the direction of the folding grooves 14. This is how the training is done. that the needle-shaped lifting tongues 23 with the strip 20 have common bearing surfaces.

To further the economical production of fast stapler, in particular with abnormal format size, the cover lid according to the embodiment according to Figs. 8 to 10 separately prepared 24 and 25, the envelope cover 24 has a deflectable edge adjacent to the folding grooves 14 26 on which the lining-up tongues 1 in the manner shown in Fig. 3 so that their free. Ends protrude over the cover 24. The second cover 25 is provided with the known inner fold 27 , the free fold wedge 28 of which, however, has a pivotable flap 29 provided with fold grooves 14. On this flap, the ESTABLISHMENT formed of a thin plastic film is g and the strips 17, 20, 23 arranged in the same manner as in the embodiment according to Fig. 5 to 7 in two insertion slots 19 replaceable. Furthermore, the folding leg 28 of the inner fold also has two breakthroughs 30 , which are arranged from the inner fold edge 9 at the same distance 10 as the corresponding slots 6 in the edge 26 of the cover 24. The bendable edge 26 is inserted between the fold legs of the inner fold 27 after the lacing tongues 1 have previously been pulled through the openings 30 . The folding legs of the inner fold 27 are then firmly connected to one another with the edge 26 by means of staples 31. This creates a loose-leaf binder which can be produced cheaply even with an abnormal format size and at the same time still has the advantages of the loose-leaf binders according to the previous exemplary embodiments.

The line-up device with the device for holding down the folded-over line-up tabs for book-like leafing through a stack of documents in a row is particularly suitable for combining a stack of documents intended for the old file due to its low manufacturing cost, especially if, according to the invention, the training is still carried out in such a way that the stack of documents lined up without Folding process can already be removed from the loose-leaf binder in a way that is suitable for the old filing system. Advantageously, for this purpose the flat file as in the embodiment according to Figure is. Produced 8 to 10 of two separate but mutually equal jacket covers 32, both of folding grooves 14 and in addition to these each have a bent over edge 33 (cf., Fig. 11). The two upturned and mutually facing edges 33 are placed on top of or against each other and firmly connected to one another by means of a holding strip 34 shown in FIG. 12 and having two folding legs by staples 31 to form an inner fold. These staples 31 have a predetermined distance from one another (see. Fig. 13), so that between the staples to de n envelope covers 32 open pockets are formed. In the same way as in the embodiment according to Figs. 8 to 10 , the device formed by a strip 20 with lifting tongues 23 made of plastic film for holding down the lining tongues 1 is arranged on a flap 35 provided with folding grooves 14, which, however, is hinged to a folding strip 36 ( fully.

t 'Fig. 14). The two rows 1 are attached to this folding strip 36 in the manner shown in FIG. 3 and have the above-described distance 10 from the folding edge. In addition, the folding strip 36 is provided on the free longitudinal side with open-edged and undercut recesses 37 , which are spaced from one another such that the tongues delimiting the undercut reach under the staples 31 of the inner fold formed by the edges 33 and the retaining strip 34, if the folding strip 36 is pushed back into the pockets of the inner fold after the associated cover 32 has been bent back. To allow the lined-up tongues 1 to pass through, the folding legs of the retaining strip 34 are provided with open-edged recesses 34a in the area of the lined-up tongues emerging from the lined-up strips. Since the Innenfalzes pockets are provided on both longitudinal sides, can thus in each flat file two tabs 35 (see. Fig. 15) with j e a fold strip 36 are housed for two different types of stitching. each flap 35 with a folding strip 36 thus represents an easily replaceable stapling strip which can move into the old filing when the stack of documents is closed, while the two pass through the inner fold. The cover lid32 is connected to one another and can be reused. Of course, the pockets formed according to the invention by means of the retaining strip 34 and the filing strip formed according to the invention can also be provided for the usual quick-release binders. A strip 41 according to the embodiment according to Fig. 4 can also be fixedly arranged by means of glue 16 on each pivotable tab 35 at the location of an exchangeable device with lifting tongues in the two embodiments according to Figs. 5 to 7 and 8 to 10 , as shown in Figs 14 and 15 is shown.

The fifth exemplary embodiment according to FIGS. 1 & to 19 differs from the previous exemplary embodiment 11 to 15 only in that each cover cover 38 has a fixedly arranged binding strip. For this purpose, each cover cover 38 is widened from the start by the width of the filing strip and is folded over at one longitudinal edge in accordance with the widening. This creates a reinforced double-layer folding strip 32, which in turn is provided with open-edged and undercut recesses 37 and with two rows 1 according to Fig. 3 . In the flap 40, which is pivotably articulated on the folding strip 39, folding grooves 14 are arranged in the same way as in the cover cover 38. . As the means serving for holding down the lining-up tongues 1 strip 42 with the - arranged # Lbhebezungeii 23 in accordance with the embodiment of Figures 5 to 7 interchangeable in an additional cover sheet 43, the pivotable on: When the cover lid 38 according to Fig 16 is. Tab 4U is attached by transverse glue applications 16. The insertion slots for the strip 42 are punched in the strip-shaped cover sheet 43, whereas in the case of the envelope cover 38 according to Fig. 18 a strip 41 according to the embodiment according to Fig. 4 or 14, 15 is provided as a device on the pivoting flap 40 and is provided by means of glue applications 16 is attached. The exchangeable strip 42 with the lifting tongues 23 differs from the one according to FIG. 6 only in that it has a constant width, so that the lifting tongues 23 form stops and a longitudinal displacement in the egg plug slots. impede. Through the strip-shaped cover sheet 43 on the flap 40 in Fig. 16 is intended to prevent that the lining-up tongues 1 insteckschlitze when flipping through the through E can emerge on the other side of Lasche40. The strip-shaped cover sheet 43 therefore fulfills the same task as the tab 18 in the exemplary embodiment according to FIG. 23, FIG. 7.

For removably connecting each pair of cover lid 38 according to Fig. 16 and 18 of the holding strip 34 is in turn connected to the open-edged recesses 34 a to Fig. 12, the Falzschenkel j edoch from the outset in a predetermined distance by the staples 31 be connected, in such a way that the two folding strips 39 of the envelope cover 38 can be inserted between the folding legs with a slight clamping, the tongues delimiting the undercuts in turn reaching under the staples 31 arranged at a corresponding distance (see Fig. 17).

Major 'ch this design, it is possible to merge different colored cover lid for two Stapling to a flat file, each Heftungsart is already visible from the outside through the color of the cover lid and are each at the same time the advantages of the quick binder according to Fig. 1 to 4 or according to Figs. 5 to 7 . Fig. 19 shows the loose-leaf binder assembled in this way in the finished state.
