Abstract

A filing device produced as a continuous one-piece body from a sheet or foil by a punching - stamping process has sequencing tongues supported as bending-elastic compression members moving easily with the folding movements of the file covers in insert strips and which are provided with locking members for easily detachable locking in their fastening position. This avoids bending of the sequencing tongues when closing the file covers and the sheets of the fastened sheet layers can be easily turned over and back along the sequencing tongues without the latter accidentally sliding out of the insert strips.

Description

The invention relates to a filing device for sheet layers provided with perforations, consisting of a one-piece from a flat, flexible blank, of substantially constant thickness, such as a plastic film or the like., As a development blank, a folding body separated out by a folding zone between a folded one Development and access position and a foldable and closed position with their inner sides folded against each other forms stapling cheeks, one of which has at least two line-up tongues for receiving the sheet layers in their perforation and of which the other as counter-cheek for each line-up tongue in an adjustable plug-in tab has a plug-in opening into which the associated line-up tongue can be inserted from its line-up position into its stitched position.

A filing device of this type is known (DE-OS 26 12 625), which is formed by a one-piece stamped part in such a way that the stapler cheeks, the row tongues and the pockets are made of one piece. With this filing device, as in general with such filing devices, it has so far not been possible to achieve as good a function as with multi-part filing devices, in particular with those filing devices in which the tabs are separated by separate subsequently attached components are formed. The behavior of the row tongues when opening and closing the filing device has so far been able to be influenced essentially only by the choice of the material and the cross sections of the row tongues, namely by the row tongues having been made relatively hard resilient from a different material than the stapling cheeks. In the case of the known one-piece solution, the row tongues are made of the same, flexible, that is less flexible than bendable or 'limp' material, which is why the risk that these row tongues are folded in on themselves when the filing device is closed and thus permanently kinked is. This could not be prevented in that the row tongues are designed in cooperation with the pockets so that the row tongues are not to be pushed through the plug-in openings of the plug-in tabs, but rather to be pulled through them, that is to say into the plug-in openings with a much larger and stronger than their buckling strength only engage smaller frictional resistance with respect to their tensile strength. If kinking of the line-up tongues is to be avoided when the filing device is closed, then practically until the end of the folding process, one hand on the inside of the counter cheek must be pulled on the ends of the line-up tongues projecting over the plug-in tabs in order to shorten the distance between the plug-in tabs and Tongue root. Since this is extremely cumbersome and a single handling error leads to permanent kink damage to at least one filing tongue, this filing device could not prevail, although the need for a one-piece, but functional filing device because of the particular advantages in terms of indestructibility, the low weight and the small spatial Expansion as well as the aesthetic clarity is definitely present.

These advantages have also become known, multi-part filing devices (US-PS 27 73 504). They are also much more complicated to manufacture, rivets or clamps for fastening individual folded layers to one another and, above all, separate rows of tongues which are adapted to the requirements in terms of their material properties. Although these row tongues are flexible, they are not flexible, which is why they have a certain amount of stability with regard to their resistance to buckling in the respective bending state. The aim of this is to ensure that when the stapler cheeks are folded up, the line-up tongues automatically slide into the plug-in openings under the loads that occur and thereby adapt their position to the respective position of the plug-in flap. However, it has been shown that the use of a flexible line-up tongue with a certain stamina in the curved shape in each case cannot prevent such a large degree of inhibition between the counter-cheek and the line-up tongue that the line-up tongue no longer slides but in itself when the staple cheeks are closed itself folded and becomes practically unusable due to the creation of a kink.

The invention has for its object to provide a filing device of the type mentioned, which on the one hand the advantages of manufacturing from a one-piece processing blank and on the other hand ensures that the Aufreihzungen can not be damaged when the filing device is used as intended.

To achieve this object, it is provided according to the invention in a filing device of the type described at the outset that the plug-in opening is so much wider than the cross-sections of at least one section which engages in it with play in the stapling position of the line-up tongue formed in one piece with the plug-in tab to form a slide opening, that this section in each position of the stapling cheeks is easily and longitudinally displaceably mounted in the plug-in tab and that the stringing tongue is supported against the sliding resistances as a flexurally elastic compression rod relative to the stringing cheek. In spite of the one-piece design, in contrast to the known solutions, by means of suitable support and formation of the stringing tongue, a flexurally elastic pressure rod, i.e. spring-back from every bending deformation, is created, the compressive strength of which, both in itself and in the support relative to the stringing cheek, is supported on the bearing in Area of the slide opening or the counter cheek is coordinated so that there is no fear of a kink when the filing device is closed due to the sliding resistances occurring in this case and introduced as pressure forces into the stringing tongue.

To support the aligning tongue with respect to the aligning cheek in such a way that the aligning tongue in the area of its articulated connection to the aligning cheek does not evade the pressure loads due to articulated movements, even if only a very small number of sheet layers are stapled, can be achieved in particular if the resilient aligning tongue has a tongue joint formed in one piece with it and the aligning cheek, with a single tongue joint lying essentially parallel to the central axis of the folding articulation zone and at least approximately in the plane of the inside of the aligning cheek, as well as a fixed tongue joint axis in relation to both the aligning tongue and the aligning cheek the line cheek merges. In contrast to this, a tongue joint which is formed by a section of the tongue root which is rounded in the form of a part circle does not have a precisely defined tongue joint axis, because a more or less large longitudinal section of the tongue root is involved in the curvature of the joint.

Such a joint very quickly tends to give way under rolling loads and thus to buckling of the stringing tongue. Even a tongue root bent to the bearing sleeve and having a clear width compared to the engaging bearing member does not have a tongue joint axis, the position of which relative to the associated end of the row tongue is precisely defined, since the bearing sleeve can rest against the bearing member due to its radial play with different sections of its inner circumference and only the tongue joint axis is determined. In the case of the subject matter of the invention, it may be sufficient if the tongue joint is not provided from the outset, but is merely designed, for example, in the sense that by a single folding or kinking of the line-up tongue in the region of its connection to the inside of the line-up cheek as a result of the changes in material in the kink cross-section that occur as a result the line-up tongue the joint can be created before the filing device is put into use. The tongue joint can also be marked from the outset, for example by a predetermined kink with less kink resistance than the other sections of the stringing tongue.

The support of the aligning tongue, which is secured against undesired articulated movements in the tongue joint, can also be improved by a stiffness of the tongue joint which is adapted to the requirements and which is expediently designed to be resilient in such a way that it resets the aligning tongue to an initial position at least in one swiveling direction. The tongue joint can be designed in such a way that when the aligning tongue is swiveled beyond this swivel angle, it swings back only over the predetermined restoring angle, that is to say then assumes an offset starting position; the tongue joint is expediently designed so that this adjustment of the starting position can be made repeatedly without the spring-back properties of the tongue joint decreasing significantly.

A particularly advantageous development of the subject matter of the invention consists in that the free end of the stringing tongue has a locking member of an easily releasable lock adjacent to an end section slidingly guided in the tack position on the inside of the stringing cheek, which prevents resistance or accidental pulling out of the stringing tongue from the tongue, however, can be unlocked by a simple transverse movement of the associated section of the stringing tongue. The locking member is designed so that in the locking position it causes resistance only to movements through or out of the plug-in tab, while in the opposite direction, i.e. in the pushing direction of the stringing tongue associated with the folding of the stapling cheeks, the easy movement thereof also directly from the locking position in no way impaired; from the locking position, the locking member can thus be lifted from its associated counter member again without any increased resistance.

Unlocking the Aufreihzungen is relatively difficult in known filing devices, since the locking members tend to jam or snag in the region of the plug openings and usually only with two hands to be passed through the plug opening. The design according to the invention makes it possible in a particularly advantageous manner to design the locking members of the row tongues in such a way that both row tongues can be unlocked simultaneously with only one hand and in the shortest possible time. For this purpose, the handle is a resiliently curved one, which is in the tack position and the access position between the slide opening and the tearing portion intended for engagement in the perforation Section of the line-up tongue, in particular the shifting section, is provided which, depending on the design of the locking members, either only has to be depressed or twisted by pressure against its side edge in order to move the locking member relative to the plug-in tab into a position in which it is no longer effective .

In order to keep the sliding resistances acting on the aligning tongue as low as possible, a separate, preferably bow-shaped insertion tab is provided for each alignment tongue, so that the sliding opening is not completely limited only by the insertion tab, but extends relatively far to the inner surface of the counter cheek and from this is limited on the associated side opposite the temple yoke. This also contributes to the fact that the plug-in tab has to be pivoted away from the unfolded zone of the fold-joint zone into its erected position from its development position, since the one-piece design with the counter cheek means that higher restoring forces act against this pivoting direction than in this pivoting direction. The plug-in tab is expediently designed to spring back in the same way as described with reference to the stringing tongue due to the properties of its tab joint. The smoothness of the line-up tongue in the slide opening is further determined by the position of the tongue opposite the center of the width of the folding-joint zone, the distance of the tongue link axis from this center expediently being at most slightly smaller, preferably at least as large as the corresponding distance of the tongue axis from this center of Folding zone is. The tab joint can be designed or applied in the same way as described with reference to the tongue joint.

When inserting the row tongues into the plug-in tabs, there is a risk in the case of one-piece stamped filing devices that the row tab is inserted through the cutout opening in the counter cheek, which is caused by the plug tab being separated out the counter cheek arises and is exposed in its area when the clip is set up; the stringing tongue is inadvertently guided through the cutout opening to the outside of the counter cheek instead of into the plug opening, which makes it difficult to thread the stringing tongue into the plugging opening. This risk can be substantially reduced in the design according to the invention by creating a guide tongue remaining in the plane of the remaining counter cheek through the shape of the clip, the width of which is expediently greater than the width of the clip legs or the associated leg sections of the tab cut-out opening is and which extends to close to the transverse boundary, so that the free end of the tongue can be placed on this guide tongue when threading the line-up tongue and then inserted in guided support through the slide opening.

So that the row tongues do not have to be deformed in order to form the locking member, but can only be produced by a simple punch cut, the locking member is essentially formed by a widened end section of the row tongue, which has a locking shoulder projecting over a side edge of the row tongue and in the area thereof forms the zone of greatest width of the stringing tongue, the width of which is expediently adapted to the width or the diameter of the associated perforation in such a way that it can just be inserted through this perforation with little movement. The section of the line-up tongue adjoining the locking shoulder to the tongue root has a width which is adapted to the width of the sliding opening in such a way that it fits between the lateral boundary edges of the sliding opening with little lateral movement play of at most 10th millimeters. For easier insertion of the line-up tongue both into the perforation and into the slide opening, one, namely the side edge adjoining the locking member, is inclined up to the free tongue end, this inclined side edge merging into the bolt shoulder at an obtuse angle.

A particularly advantageous development, in particular a filing device of the type described, consists in that the line-up tongue, which is narrower than the width of the holes in the perforation, is offset with respect to its longitudinal median plane in relation to the perforation grid so that it has a side edge on the inner boundaries of the Perforation is present, while its other side edge is at a distance from the inner surface of the perforation. If two row tongues are offset in this way, they align the sheet layers very precisely with each other through the abovementioned contact on the inner surfaces of the perforation, as a result of which the loads acting on the row tongues from the sheet layers are distributed very evenly and remain low. If the aligning edges are the side edges of the row tongues facing away from the locking members, the row tongues can carry out the unlocking movements for the latching particularly freely and can easily release the perforation when de-stitching.

The accuracy of manufacture can also have a significant influence on the safe functioning of the filing device. When the entire filing device is manufactured and completed by a single punching process, for example using a band knife, inaccuracies and manufacturing errors can arise in particular from the fact that waste particles of the plastic film or the like, which arise during punching, remain in the area of the punching knife and the following Die cuts are in the way. According to the invention, both the filing tongues and the plug-in tabs are each separated from the rest of the associated stapling cheek by cut-free separating cuts, in such a way that a cut-out opening which is congruent with the shape of the filing tab or the plug-in tab is formed and no waste particles are produced. For this production it is also advantageous if all joint grooves are produced by stamping processes from the same side of the blank, whereby this side is expediently the same side from which the punching knives are also moved against the blank during the punching cut, SD that both the separating cuts and the joint groove embossing are produced simultaneously with a single tool.

At least one stapler cheek of the stapling device according to the invention can be smaller than the sheet layers to be stapled, for example stripes. For the production of a filing device in the form of a folder, from which at least one stapler cover completely covers the stapled sheet layers, the respective stapler or folder cover forms the associated stapler cheek that is in one piece with the other stapling device. In order to achieve the described effects, it has proven particularly advantageous if the filing device consists of a polypropylene film, although it is also conceivable to use films with zones of different material properties or different materials lying transversely to the fold-joint zone, which are produced as one-piece composite films are. Furthermore, the film can have zones of different thickness, for example in a grid-like manner, in that it is provided with embossed profiles, in particular on the outside.

The filing device according to the invention is suitable for all types of perforations, that is to say for 2-fold, 3-fold, 4-fold and multiple-perforations, the expediently arranged row tongues for the alignment of the sheet layers being expediently formed by the outermost tongues. In the case of more than two aligning tongues, only two aligning tongues, preferably symmetrical on both sides of a central perforation plane, can have locking members, or all aligning tongues can be provided with locking members, with an odd number of aligning tongues expediently providing locking members only in pairs on aligning tongues.

The filing device according to FIGS. 1 to 9 is designed as a folder, which is produced as a continuous one-piece component from a film with a thickness between approximately 0 to 1.6, but in particular less than 1 mm thick, by means of a single stamped _- embossing cut that at least all parts of the actual stringing or stitching system connect to one another via one-piece connections. Two stapler cheeks, namely a line-up cheek 2 and a counter cheek 3 are connected to one another via a folding joint zone 4 and can be folded together and each form a folder cover 5 or 6, wherein the sheet layers 7 to be stapled can be completely covered between the folded folder covers.

The folding joint zone 4, which is formed in the manner of a limb joint from a plurality of joints lying next to one another in parallel and which forms the flexible back of a predetermined width of the filing device, has a plurality of parallel joint axes, an imaginary one lying in the middle of the width of the folding joint zone 4 parallel to the joint axes The central axis 8 is referred to below as the central axis of the folding-joint zone 4, regardless of whether there is a joint in the region of this central axis 8 or a central strip of the folding-joint zone 4 which is delimited by joints on both sides and is free of joints. On the inner sides 8, 9 of the two stapler cheeks, a line-up or filing system is provided adjacent to the folding joint zone 4, which essentially consists of two or more elongated strip-shaped line-up tongues 12 projecting from the inner side 8 of the line-up cheek 2 and two from the inner side 9 of the counter cheek 3 protruding, bow-shaped plug-in tabs 13 for receiving these row tongues 12 is formed. The line-up tongues 12 are used to pass through, for example, circular holes in a filing perforation 14, which is usually provided in accordance with the norm at a predetermined distance from an edge of the sheet layers 7 and with a fixed distance between their holes in all sheets. The line-up system or its line-up elements are arranged mirror-symmetrically to a central plane 15 which is perpendicular to the central axis 8 and which is expediently located in the middle between the continuous outer boundaries of the stapling cheeks parallel to it.

The aligning tongues 12, which each connect to the aligning cheek 2 via a tongue joint 16 with a tongue joint axis 17 parallel to the central axis 8 and are punched out of the aligning cheek by a non-cutting, interrupted separating cut in the tongue joint, protrude over a part of the width of the aligning cheek in the development position according to FIG. 2 2 from the folding joint zone 4 and at right angles to it freely.

Their tongue joints 16 or their common tongue joint axis 17 lie at a distance from the adjacent boundary of the folding joint zone 4 which is approximately half the distance 1 of the perforation 14 from the associated edge of the sheet layers. The plug-in tabs 13, which are considerably shorter than the aligning tongues 12, protrude in the developed position in the same direction as the aligning tongues 12, free of tab joints 18 which lie in a common tab joint axis 19 parallel to the tab joint axis 14 or the central axis 8. The plug-in tabs 13 are also cut free from the associated stapling cheek by a blank cut, which is only interrupted in the area of the tongue joint 18, which is designed as a double joint, but the distance of the link joint axis 19 from the associated outer boundary of the folding joint zone 4 is smaller than the corresponding distance of the tongue joint axis 17 , but is greater than the average distance of the perforation 14 from the associated sheet edges of the sheet layers 7.

For the use of the filing device 1, the row tongues 12 and the tabs 13 are folded over by the user by approximately 180 ° to the inside of the stapling cheeks 8, 9, whereby due to the selected material and the articulations they remain in a right-angled position after a return spring swing. All joints are formed by joint grooves 20 to 24, which are stamped from the outside 10, 11 in the manner of film hinge grooves parallel to one another into the surface of the blank, the material behavior of the blank, in contrast to the arrangement shown, usually leading to the fact that in the Area of each embossment on the inside 8, 9 of the stapler forms a groove in the same direction, although as a counter tool for the profiled embossing tool effective on the outside, no profiled die is used, but a continuously smooth, flat counter surface, which is both the counter tool for all punching knives and also for everyone with this structurally combined embossing tool.

Due to the position of the cross-section remaining after the embossing, which is reduced in comparison with the thickness of the starting film, in the region of the bottom surface of each joint groove, it follows that the joint axes lie between the outer surfaces of the film, but much closer to the inner sides 8, 9 of the stapling cheeks. The joint grooves 22 to 24 of the folding joint zone 4 are provided in pairs on both sides of the center of the width of the folding joint zone 4, the outermost joint grooves 24 forming the outer boundaries of the folding joint zone 4.

Each of the two line-up tongues 12, which are of mirror-symmetrical design with respect to the central plane 15, forms a line-up section 25 directly adjoining the tongue joint 16 for engaging in the associated holes in the hole 14, the sheet layers 7 lying flat over the entire surface on the inside 8 of the line-up cheek 2, one by a continuous continuation formed with the same cross-sections, longer displacement section 26 and an adjoining this, the free tongue end 28 forming end section 27. The width of the widening section 25 is, for example, almost a quarter smaller than the diameter of the perforations 14 of the sheet layers 7, but the the two side edges 29 of the reaming sections 25 of the two row tongues 12, which face away from one another and are continuous to the rounded tongue end 28 in a straight line and parallel to the central plane 15, are at a distance from one another which is substantially equal to the mean distance 30 of the holes in the perforation 14 from each other ch the diameter of this perforation or, in contrast, is only smaller by a small amount of movement. As a result, these side edges 29 form alignment edges for the sheet layers 7, so that parallel to the central axis 8 of the folding-joint zone 4 they can practically perform no relative movements with respect to the row tongues 12 and thus with respect to the row cheek 2. The length of those sections of the line-up tongues 12 which form the line-up section 25 is dependent on the thickness or height of the sheet layers 7 respectively on the row cheek 2, so that the section of the respective row tab 12 projecting above the top of these sheet layers then prevents Section 26 forms.

The width of the shifting section 26, which along its length, in one plane with the side edges of the line-up section 25, has side edges 31, 32 which are parallel to one another, is equal to the width of the line-up section 25. This allows sheets of the sheet layers 7 to be unhindered by Raised layers of sheets are lifted off and moved with their perforations back and forth under sliding along the shifting section 26, and so they are opened and then opened again with complete separation from the stack of sheets. At the same time, the sliding section 26 serves as a guide when rows of sheets are lined up on the row tongues 12 or when sheets are removed from these row tongues.

Each plug-in bracket 13 forms a sliding opening 33, which is limited in view, which, when the plug-in bracket 13 is set up, is provided in a plane which is transverse to the inner side 9 of the counter cheek 3 and parallel to the central axis 8, and whose central plane 34, which is perpendicular to the central axis 8, with the associated central plane of the sliding Section 26 or Aufreiufschnittes 25 coincides.

Each of the two bracket legs 35 of the plug-in bracket 13 articulated via a separate bracket joint 18 on the counter cheek 3 forms a lateral boundary 37, 38 of the slide opening 33 with its inner edge, these lateral boundaries being continuously parallel to one another and in via the clear height of the bracket 13 to the inside 9 of the counter cheek 3 perpendicular levels. The yoke yoke 36 of the plug-in tab 13 forms an outer boundary 39, which is parallel to the plane of the inner side 9 of the counter cheek 3, is approximately straight through to the lateral boundaries 37, 38. The inner transverse boundary of the slide opening 33, which is adjacent to the counter cheek 3, is directly through the inner surface of the counter cheek 3 is formed. The clear width of the sliding opening 33, which is slightly wider than the width of the bracket leg 35, is only a small amount of movement greater than the width of the sliding portion 26 of the stringing tongue 12, such that the boundaries 37 to 39 sliding surfaces for the form smooth-running guidance of the side edges, as well as the outside of the sliding section facing away from the counter cheek 3. The opposite the width greater, clear height of the slide opening 33, which is smaller than twice its width, is greater than the greatest width of the stringing tongue 12 in the region of the end portion 27 or at least so large that the corner diagonal dimension of the slide opening 33 is at least so large how this greatest width of the end section 27 is. The width of the strap J _Q chs 36 is approximately equal to that of the mutually equally wide strap leg 35th

The greatest width of the line-up tongue 12, which lies in the area of the upper aisle of the shifting section 26 into the end section 27, results from a locking member 41 provided at the end section 27 of an easily releasable locking device 40, by means of which the breathing tongue 12 counteracts when in the tacked position accidental pulling out of the clip 13 is secured. The locking member 41 formed by widening the line-up tongue 12 forms a locking shoulder 42 projecting beyond the side edge 32 of the shifting section 26 facing the other line-up tongues 12, the inner end 44 of which connects directly to the associated end of the side edge 32 and is approximately at right angles starts from this side edge 32, specifically, for example in the form of a part circle, in a convex arc. From the protruding end 45 of the locking shoulder 42 there is a straight insertion edge 46 converging at an acute angle to the free tongue end with the side edge 31, which introduces the associated side edge of the end section 27 which extends in a straight line up to the rounded tongue end 28. The counter-member 43 for the locking member 41 is the edge of the lateral boundary 38 of the slide opening 33 which, when the plug-in tab 13 is set up, lies on its side facing away from the folding-joint zone 4. The slope angle of the locking shoulder 42, which decreases outwards due to the arch shape, is selected such that when the locking member 41 is pulled a little way into the sliding opening 33 under tensile loading of the line-up tongue 12, no clamping or, respectively, between the line-up tongue 12 and the plug-in tab 13 Self-locking occurs, but that the line-up tongue 12 under shear load in the direction of the free tongue end 28 without greater resistance than the sliding resistance between the sliding section 26 and the plug \ tab 13 can be longitudinally pushed again relative to the insertion tab 13 in such a way that the locking shoulder 42 is released from the insertion tab 13 without resistance. The greatest width of the aligning tongue 12 in the area of the locking member 41 is smaller than the width of the plug-in tab 13, preferably approximately half as large, so that the locking member 41 projects beyond the side edge 32 by less than the width of a bracket leg 35.

Since the length of the line-up tongue 12 between the tongue joint 16 and the locking member 41 decreases its compression rod effect, this length is slightly smaller than the arch-shaped articulated connection of the line-up tongue 12 to the line-up cheek 2 to maintain this effect even in the locking position. As a result, the line-up tongue 12, which resiliently resiliently bends resiliently when the locking member 41 engages in the locking tab in the locking position 13 under its own tension and, if appropriate, in the perforation 14, supported by the sheet layers 7, an arch which is curved upward in side view and which extends from the alignment cheek 2 to the locking tab 13 has decreasing radius of curvature and in the region of the plug-in tab 13 by resilient abutment on the boundary 39 and by resilient support in the region of the free tongue end 28 on the inside 9 of the counter cheek 3 merges into an oppositely curved flat arc. As a result, top sheets of the sheet layers 7 can be easily opened up to the stop on the plug-in tab 13. When these pages are turned back, the line-up tongue 12 is subjected to a tensile load, whereby by engaging the locking shoulder 42 on the counter-member 43 despite play movements of the locking member 41 relative to the plug-in tab 43, the line-up tongue 12 can be detached from the plug-in tab 13. 5 and 6, the line-up tongue 12 slides in the region of its tongue end 28 along a slideway 48 formed by the inside 9 of the counter cheek 3 and with its associated surface on the boundary 39 of the slideway 33, the slidable system is secured in each case by the slight resilient bias of the string tongue 12. In the closed state, the slide opening 33 is essentially congruent over the perforation 14 of the sheet layers 7 or over the tongue joint 16.

To unlock the easily releasable locks 40, each row tongue 12 has a handle 49 which is formed only by a section of at least one side edge 31 or 32 of the row tongue 12. 3 and 4 are pressed against a side edge 31 and 32 of the shifting section 26 of the stringing tongue 12, the shifting section 26 yields to this force in the associated direction, the section of the line-up tongue 12 adjoining the tongue end 28 resiliently rotates about its longitudinal central axis 50 under the occurring forces, so that the locking member 41 in the direction of a diagonal position with respect to the slide opening 33 with continued engagement of the tongue end 28 on the inside 9 inclined and is thus free of the counter member 43. The displacement of the displacement portion 26 caused by the pressing force applied at the same time a reduction in the distance between the tongue ₆ and bolt member joint 1 41st so that when the locking member 41 is released, it is pulled out of the plug-in tab 13 and the line-up tongue 12 is released from the plug-in tab 13. In Fig. 3 a dot-dash line indicates a position of the line-up tongue 12 which it assumes when it is pressurized for unlocking on the longitudinal side remote from the locking member 41; Here, the Aufreihzung 12 rotates in such a way that the locking member 41 pivots towards the inside 9 of the Aufreihwange 3, so that the continuous straight side edge 31 to the tongue end 28 on the boundary 39 of the slide opening 33 slides. This handling also complies with the fact that the perforation 14 is so eccentric in the manner described that the widening section 25 has a certain amount of play in this direction relative to the sheet layers 7. Also, since the side edges 31 are the side edges of the two facing away from one another, they can be used together locked row tongues 12, the unlocking can be carried out very easily at the same time with the fingers of a single hand, for example with the thumb and forefinger by opposing pressure loading. If the line-up tongue 12 is pressurized for unlocking in the area of the other side edge 32, the locking member 41 swivels in the opposite direction away from the inside 9 of the counter cheek 3 and then jumps over the boundary 39 of the slide opening 33, which is relatively sharply angled into the lateral boundaries 37, 38 passes.

The slideway 48 for the line-up tongue 12 has an extension in the form of a slideway 51 which extends through the slide opening 33 and extends a little way beyond the plug-in tab 13 to the folding-joint zone 4, the width of which is flush with the slide opening 33 and the width of the slide opening 33 and which is formed by a freely projecting guide tongue 52. This guide tongue 52 results from the waste-free separating cut with which the plug-in tab 13 is punched out and is the part of the separating cut which is separated out to form the slide opening 33. The tabs neck opening formed by the cutting out of the insertion flap 13, bow-shaped 53 in the counter-jaw 3 is bounded on the inside of its Bügeischenkel 54 by the guide tongue 52, which at its free end with a relatively small distance from the transverse boundary of the cutout opening ₅ 3 in the plane the opposite cheek 3 lies and connects with its tongue root to the rest of the opposite cheek 3 without joints. When inserting the free end of the line-up tongue 12 into the plug-in tab 13, the line-up tongue 12 can be conveniently placed on the slideway 51 of the guide tongue 52 and then inserted into the slide opening 33 under shear load. In the area of the free tongue end 28, the line-up tongue is narrower than in the area of the shifting section 26. The separating cut forming the respective line-up tongue 12 results in a tongue cutout opening 55 in the line-up cheek 2. The line-up tongue 12 is connected to the line-up cheek a tongue root 56, which the associated end portion of the Line-up section 25 forms or is formed by this.

The dimensions between and within the line-up tongue 12, on the one hand, and the plug-in tab 13, on the other hand, can significantly influence the extent to which the line-up tongue 12 is loaded in each position only as a non-buckling pressure rod, given the buckling rigidity of the line-up tongue 12. In most cases, the highest possible plug-in tab 13 or slide opening 33 will be sought, which leads to the fact that - since a too close approach to the associated outermost joint groove 24 is undesirable in most cases - the plug-in tab 13 or the outer transverse boundary 39 of the slide opening 33 is relatively far away from the folding joint zone 4 when the tongue 13 is completely folded over. This position of the outer transverse delimitation is also important for the closed state of the filing device 1, since the transverse delimitation 39 should be at a distance from the folding-joint zone 4 which is - for example by slightly more than half the perforation diameter - larger than the same distance of the Tongue hinge 16 is so that the line-up tongue 12, when the stapler cheeks 2, 3 are closed, passes from the tongue hinge 16 or from the tearing section 25 over a sheet that is as large as possible and therefore uncritical for permanent deformations into the shifting section 26 or passes through the slide opening 33. On the other hand, the distance of the tongue joint 16 from the folding joint zone 4 is to be kept so small that no unnecessary space is lost between the associated edges of the sheet layers 7 and the folding joint zone 4. In some cases, the design according to FIG. 21 is particularly favorable for this.

Since the behavior of the sequencing tongue 12 as a non-buckling forming, but also curved push rod directly from pter at aufgekla ^p access location of the filing apparatus 1 and with the simultaneous tack position of the line-up tongue 12 given the maximum kink length, i.e. the length between the sliding support on the plug-in tab 13 and the support in the area of the perforation 14 of the sheet layers 7 or the tongue joint, the lock 40 forms the limitation of the length of the displacement Section 26, if necessary, plus the length of the reaming section 25, which prevents pulling out of the ratchet tongue 12 from the plug-in tab 13 and thus preventing the section acting as a compression rod from being extended to the extent critical for kinking.

As can be seen in particular in FIG. 4, it is also important for the load on the line-up tongue 12 as a pressure rod which frictional resistances act on it in the area of the tongue end 28 on the side facing away from the abutment on the transverse boundary 39 of the slide opening 33 when the end section 27 slides on or near the tongue end 28 on the inside 9 or the slideway 48; these frictional resistances in turn increase with the angle 60 at which the end section 27 connects to the counter cheek 3, which is the largest in the locking position and which is also dependent on the length of the end section 27. This acute angle 60 should be substantially less than 45 ° or less than 30 ° or 20 °, in particular approximately in the order of 15 °, and receives a favorable value, for example, if the length of the end section 27 is approximately two and a half to three times that Height of the transverse boundary 39 of the plug opening 33 above the slideway 48 is. These values apply in particular to the stapler cheeks 2, 3 just spread out according to FIG. 4, since here the angle 60 is greatest. As a result of its self-straightening, resilient properties, the counter cheek 3 also runs in the access position in an S-shaped arc from the folding-joint zone 4 first upwards and then again in the region or beyond the tongue end 28 downwards.

10 to 23, the same reference numerals as in FIGS. 1 to 9 are used for corresponding parts, but with different letter indices.

In the embodiment according to FIG. 10, on the side of the one-piece transition or connection of the tongue root 56a of the stringing tongue 12a facing the folding joint zone into the stringing cheek 2a, a push-through opening 57 which is aligned with the longitudinal direction of the stringing section 25a is provided, the width of which is equal to the width of the Aufreiafschnittes 25a and which is formed by a non-waste, U-shaped separating cut with cut legs facing the tongue cutout opening 55. The length of this cut piece is the same or only slightly greater than the material thickness of the stringing tongue 12a, the through-opening 57 being provided at a distance from the folding-joint zone. For use, the line-up tongue 12a is raised from its development position not to the inside, but to the outside 10a of the line-up cheek 2a, then with its free end from the outside 10a inserted through the push-through opening 57 and pulled to the inside 8a of the line-up cheek 2a so that it between the tongue root 65a and the push-through opening 57 on the outside 10a of the stringing cheek 2a, the section lies closely against this outside. The U-shaped separating cut forms a tab tongue 58, which is pulled up when pulling the row tongue 12a toward the inside 8a of the row cheek 2a and rests with a prestress on the surface of the row tab 12a facing away from the folding hinge zone in the area of the inside 8a of the row cheek 2a. As a result, the tab tongue 58 forms a support member for the aligning tongue 12a in the region of its articulated connection to the aligning cheek 2a located on the inside of the push-through opening 27, the tab tongue 58 tensioning the aligning tongue 12a in this area against the opposite boundary of the push-through opening 57. In this area, the line-up tongue 12a can be provided with a film hinge-like tongue joint, or the tongue joint 16a results without one A change in the tongue cross section would be necessary in that the line-up tongue is supported on the edges of the push-through opening 57 and the tab tongue 58 in the manner of a knife-edge bearing.

11 has a side edge 32b which is associated with the locking member 41b and which, from the tongue joint 16b to the locking member 41b, converges in a straight line at an angle of a few degrees in the direction of the tongue end 28b with the other side edge 31b, so that the tongue root converges 56b results in a gradual reduction in the width of the widening section and the displacing section 26b.

In the embodiment according to FIG. 12, the widening section 25c has a constant width, while the side edge 32c lies obliquely between the widening section 25c and the locking member 41c, as described with reference to FIG. 11. The oblique side edge 32d according to FIG. 13 extends from the locking member 41d only over part of the length of the displacement section 26d. As shown in FIG. 13, the locking shoulder 42d can also lie approximately at right angles to the longitudinal central axis 50d.

The line-up tongue 12e according to FIG. 14 has two locking members 41e protruding mirror-symmetrically over both side edges 31e, 32e, each with a locking shoulder 42e, in such a way that the line-up tongue 12e is formed symmetrically with respect to its longitudinal central axis 50e.

For this line-up tongue 12e, a sliding opening is expediently provided, which increases in width from its outer transverse delimitation in the direction of the delimitation by the counter cheek to the width of the line-up tongue 12e in the region of the locking members 41e. As a result, the line-up tongue 12e, which is locked under its own pretension at the transverse boundary, only needs to be pressed down in the region of the sliding section until the locking members 41e have reached the wider area of the sliding opening, after which the line-up tongue 12e is pulled by pulling on the sliding section is released from the clip.

15 shows a plug-in tab 13f with a widened slide opening 33f which is also suitable for the row tongues according to FIGS. 1 to 13. The broadening results from the fact that one of the two side boundaries of the slide opening 33f is arranged correspondingly obliquely.

In the embodiment according to FIG. 16, which is particularly suitable for the row tongue 12e according to FIG. 14, the widening of the slide opening 33g results from a semicircular transverse boundary 39g with parallel lateral boundaries 37g, 38g.

The line-up tongue 12h according to FIG. 17, which is particularly suitable for a plug-in tab 13h according to FIG. 18, has a constant width over its entire length and, as the locking member 41h, has a side lying between its side edges 31h, 32h in the middle of its width on all sides enclosed bolt opening 42h, which is associated with a bolt cam 43h in the transverse boundary 39h of the slide opening 33h of the plug-in tab 13h. The bolt opening 42h tapering at an acute angle in the direction of the tongue root 56h is at least partially penetrated in the locking position by the locking cam 43h, the locking cam 43h resting against the transverse limit of the locking opening 42h when the sliding section 26h is under tensile load and due to the triangular design of the bolt opening when the thrust is applied 42h can easily release from this. To unlock the sliding section 26h only needs to be pressed down.

In the embodiment according to FIGS. 19 and 20, the line-up tongue 12i, as a locking member 41i, has a locking tongue 42i which is punched out without being cut and which projects freely in relation to the tongue root 56i and is raised up relative to the line-up tongue 12i in such a way that it engages with the bracket in the latched position -Yes the plug tab comes. In this case too, depressing the shifting section of the stringing tongue 12i is sufficient to unlock.

21 is arranged so that it is directed away from the folding joint zone 4j in the developed position. 22, the plug-in tab 13k can also lie in the development position in the region of the folding-joint zone 4k, that is to say it can be punched out of it, the plug-in tab 13k protruding freely in this development position in the direction of the tongue root of the associated stringing tongue, and preferably on its side facing away from this tongue root has only tab link 18k. The plug-in tab 13k is not bow-shaped, but rather elongated or elongated rectangular ring-shaped, so that it itself delimits the slide opening 33k continuously on all sides.

The locking shoulder can also be straight following the side edge 32, for example over part of its length. In any case, the tip of the locking member is expediently rounded such that the rounding passes tangentially into the insertion edge 46. Due to the oblique or rounded locking shoulder 42, the Aufreihzun ^g e can be unlocked particularly easily and pulled out of the perforation 14 of the sheet layers 7.

As shown in FIG. 23, holding eyes 59 which are formed in one piece from the filing device and are preferably also bow-shaped, so that they can be produced without waste. These retaining eyes 59 can be provided, for example, in the perforation grid and adapted to the filing dimensions associated with this perforation, so that the entire filing device in a further filing device or the like. can be included. The holding eyelets 59 to be set up from the development position to the outside of the filing device are arranged in alignment with the row tongues 12m, a holding eyelet 59 being provided in each case between a tongue root 56m and the folding-joint zone 4m. In the developed position, the retaining eyelet 59 protrudes toward Tongue root 56m freely, while the ends of your stirrup legs can lie in the area of the folding joint zone 4m, in particular the associated outermost joint groove 24m, so that the retaining eye 59 also passes over a joint into the filing device without a separate joint groove being required for this.

The filing device according to the invention is particularly suitable where sheet layers are not only held together in the manner of a permanent bond, but where it is necessary to remove or file sheets again and again, where a more frequent sheet change and easy leafing of the filed sheet layers is required. At least one of the stapler cheeks or at least one of the folder covers can be provided with a, for example rectangular, window cutout which is expediently arranged in the upper folder cover 6 according to FIG. 1; when using a sheet stapled in the topmost position in the filing device with correspondingly easy-to-produce lettering, a separate identification lettering of the respective filing device can be dispensed with. The corners of the folder covers are appropriately rounded in a quarter circle to protect them.
