The cover latch has at least one flexible strip (7) which is attached to the base latch, where the strip has two tongues (13,14) which pass through holes provided in the stack of paper. A slidable cover rail (8) is provided on top of the cover latch which consists of two sections (22,22') which can be slid together on the cover latch.

Description

The invention relates to a device for stapling a Stack of document sheets and, if necessary, for storing such Staple in a folder with filing mechanism, including one under the Base tab to be placed on the stack of documents, one on the stack of documents Cover flap to be arranged, at least one flexible flap, on the base flap fixable and / or fastened tab strips, the two tabs for the purpose of stapling the document sheets through pairs of perforations of the Document stack and the top flap are threaded through and above the Document stack are bent at the end of the cover flap, and at least one on the cover flap including the tongue ends slide-on cover profile rail with undercut longitudinal edges for Grasping the longitudinal edges of the cover flap.

A generic device is in European Patent 0 654 362 of the applicant. This has a first peculiarity in that that the bent tongue tabs are opposite the longitudinal axis of the The cover flap is slightly inclined and therefore runs side by side. The one-piece, deferred cover profile strip therefore finds a frictional hold at most, since in the closed position there is neither a latching nor snagging on the bent tongue ends is possible. The cover profile strip can therefore slide down from the cover flap when the relevant stack of documents comes out a folder is taken so that all the layers of the stack as well as the Perforations no longer penetrate the folder mechanism be penetrated. In this case there is a risk that the cover profile strip go unnoticed to an exposed position and, for example, kinked there can be. It is also necessary to open the stapling mechanism Push the cover strip completely off the cover flap as it otherwise could also buckle. This has the consequence that after each Then remove a sheet from the cover flap must be threaded.

This results from the disadvantages of the prior art described Problem initiating the invention, a generic stapling device of this type to further develop that the cover profile rail, if possible, also for removal one or more sheets can remain connected to the cover flap so that the handling of the stapling device is further simplified. Furthermore, the Stapling device to be designed so that the risk of accidental Damage due to improper handling is as low as possible.

According to the invention, this problem is solved in that the Cover rail is divided in two in its longitudinal direction, such that the two Parts from opposite end faces can be pushed onto the cover flap.

By dividing the cover profile the effective length of a Part of the same is significantly reduced, the unfavorable is reduced Leverage between the top flap and that of the middle one Tack area of the same cover strip pushed down so that none There is a risk of damage to the stapling mechanism, even if the two Cover profile rail parts not completely pushed down from the cover flap become. Therefore, handling is easier since after removal or the sorting of one or more sheets, the cover profile rail time-consuming first has to be pushed back onto the cover flap, rather, the cover rail parts remaining in it only have to again be pushed together.

It has proven to be favorable that the cover profile rail is divided in the middle, so that the cover profile rail parts have an identical shape. Through this Measure can be achieved that both cover profile rail parts with the same injection mold are made, so that the effort for Manufacture of injection molds despite the increase in the number of moving parts the stapling device according to the invention is minimal.

It is within the scope of the invention that the cover rail parts on it Butt edge each an extension extending approximately over half its length have, with a recess in the other portion of the abutting edge corresponds. In this case there is an opaque connection between the two cover profile rail parts so that the cover flap is not visible, too if the cover profile rail parts move slightly.

Further advantages result if the cover profile rail parts are preferred in the area of their abutting edge a profile that increases the grip, for example in Form of a corrugation. When opening and closing the Cover profile rail parts experience their area adjacent to the abutting edge permanently a guide along the common cover tab so that this area is particularly suitable for actuating the cover profile rail parts. There the cover profile rail parts especially because of their small cross-section touched superficially, but can not be grasped properly, the Profiling according to the invention for a sufficient frictional engagement during Opening or closing.

It has also proven useful that the profiled grip areas on the top and are provided on both longitudinal edges of the cover rail parts. Thus, a person has the option of actuating only one finger on the to lay the relevant cover profile rail part, or with two fingers thereof to grasp both longitudinal edges.

The user friendliness can be further increased by the fact that profiled grip areas are raised. In such a case, the frictional effect of the profiling by a form fit on the by the raised area gradation are supplemented so that the Reliability in operation is further improved.

The invention allows further development in that the profiled and / or raised grip areas an arrow-like pointing in the direction of insertion To have shape. These areas therefore clearly indicate the closing direction of the cover profile rail parts according to the invention, and these arrows can complement each other to an "X" when fully pushed together, which shows at a glance that the cover profile rail closed is.

The invention further provides that the undercut of the Cover profile rail parts continuously on their peripheral face is led around. This makes the closing movement one Cover profile rail part · limited, even if the other Cover profile rail part is still open, so that the same no undefined Can take positions. Furthermore, this increases all-round Undercut the stability of the cover rail part in question Transverse direction, so that an undesirable transverse arching is avoided.

The invention also offers the possibility that the cover rail parts each have a perforation, each with a perforation of the base tab and the Cover tab is aligned. On the one hand, these perforations serve the purpose of a additional storage of the stapled stack in a folder od. Like. To allow, on the other hand, the cover profile rail parts in such a case a positive connection with the brackets of the relevant folder and are thereby also fixed in their direction of displacement along the cover flap, so that accidental postponement is completely impossible.

The invention can be further developed in that the Cover profile rail parts in the areas adjacent to the abutting edge in the Have undercuts protruding projections that engage with lateral projections and / or gradations on the longitudinal edges of the Cover tab can get to thereby an opening movement of the counteract the relevant cover profile rail part. This Design feature serves the purpose of accidentally loosening the Avoid cover rail parts from the cover tab, even if the Shifting movement not penetrating through corresponding perforations Hole punch is prevented. In such a case, one can Brief transport or the like. No parts of the filing mechanism according to the invention are lost so that their functionality is permanently ensured.

This design specification can be concretized in such a way that the Longitudinal edges of the cover flap near the end faces thereof widening gradations are provided, which in the open position of the Cover profile rail parts on those protruding into the undercut area Extensions come to the system and thereby limit the opening movement. By loosening the cover profile rail parts from the cover flap opposing design elements of the cover flap as gradation trained, it maintains maximum stability, so that a almost undesirable deformation of the cover flap in this area is excluded, so that the cover profile rail parts do not go unnoticed the gradations in question can slide away. On the other hand, this Gradations preferably laterally outside inner perforations for the Binding together individual sheets of the relevant stack of documents are arranged, the two cover profile rail parts can still so far be pulled apart so that the tabs are comfortably erected and then the cover flap with the cover profile rail parts attached to it can be lifted to individual sheets of the stack of documents remove or add more sheets.

In a further improved embodiment, the Cover tab near the center of which lateral projections are provided, behind which the projections of the Cover rail parts can engage in their closed position for locking. These projections allow one or both cover rail parts in the To fix the closed position so that the during a storage period on the Cover profile parts acting opening forces are absorbed, even if the storage is not in a folder, the bracket peripheral Perforations in the various layers of the filing mechanism according to the invention succeed.

In particular, in this latter embodiment, additional Sealing eyelets on the longitudinal edges or the top of the Cover profile rail parts are provided close to the butt joint, by which can be threaded through a wire provided with a seal, for example so that an opening of the cover profile rails inevitably destroys the Sealing brings with it and is therefore immediately recognizable.

Preferably, the cover profile rail parts are on both longitudinal edges such sealing eyelets provided so that when using identical Cover profile rail parts each have two eyelets on the same longitudinal edge of the Cover rails are available. Something similar could also be achieved through this achieved that an eyelet on the top of the cover rail parts is provided, but this would increase the overall height condition the stapling mechanism according to the invention, so that the storage capacity of a folder would be reduced. This disadvantage can be solved by arranging the Sealing eyelets on the longitudinal edges of the cover rail parts largely be avoided.

The invention allows a further embodiment in that the Cover flap a widening approximately midway between the two end faces has, such that the adjacent in the closed position in the The undercut protruding extensions of the Cover profile rail parts the longitudinal edges of the cover flap to form a compress the slight transverse curvature of the same. Since the Cover profile rail parts under the cover flap could the same of the Stack of documents are lifted off, so that there is an unattractive bulging of the could adjust the middle split cover. Due to the transverse curvature of the in the area of its longitudinal edges, the top flap is given one internal tension, which is a straight shape of the cover plate and thus also favoring the cover profile rail pushed on, so that too despite their central subdivision, the individual cover profile rail parts one take exactly aligned position, which is the compactness of the promotes stapled stack of documents.

An arrangement is preferred by the invention, wherein the cover flap in the Area between their inner perforations a groove-like depression for Inserting the bent tongue ends. By doing this deepening is preferably continuous between the inner perforations, the tongue ends can fit in it, no matter how thick it is stapled stack of documents. It is particularly important that the Cross section of the groove-like recess approximately the cross section of the tongue ends corresponds to or is slightly larger. In that case, they can Cover profile rail parts conveniently over the bent tongue ends gliding away, thereby preventing them from getting caught anyway is that the two cover profile rail parts only to the middle of the Cover plate are pushed and the tab ends automatically press down.

Finally, it corresponds to the teaching of the invention that the cover flap and / or the cover profile rail parts are extended beyond the outer perforations, and preferably about 1.5 to 2.5 times the width of the cover flap or about 3 to 4 times the hole diameter. This ensures that the opened cover profile rail parts are always sufficient remain on the cover flap, even if they are up to the Opening movement limiting gradation are pulled out, so that on the cover tab acting as a guide from the inside of the Undercuts of the cover profile rail parts exerted little force remain and thereby damage the stitching mechanism even at one improper handling are largely excluded.

Other features, details, advantages and effects of the invention will be apparent derive from the following description of a preferred Embodiment of the invention and with reference to the drawing.

As is clear from Fig. 1, the stapling device 1 is used for stapling together a stack of documents 2, e.g. from a variety of A4 sheets 3 consists. The stapling device 1 sits in the middle on the left edge according to DIN So-called booklet margin 4 - the stack of documents 2.

The structure of the stapling device 1 is clear from FIGS. she consists made of an essentially rectangular, flexible, flat material manufactured base plate 5 with rounded corners (Fig. 2), a strip-shaped, profiled cover plate 6 (Fig. 3a or 3b) made of rigid plastic material or preferably sheet metal, a tab strip 7 (Fig. 10) made of a metal sheet, possibly plastic-coated, or made of rigid Plastic material is made, and a relatively rigid, plastic manufactured, two-part cover rail 8 (Fig. 5, 6 and 7).

The base plate 5 (FIG. 2) has a perforation 10 in the center of its longitudinal center line 9 on, which consist of two holes 11 consists. The base plate 6 is also with two transverse to its longitudinal center line 9 extending mounting slots 12 provided on the connecting straight line sit within the same between the two holes 11.

As is clear from Fig. 9, the two mounting slots 12 are used Attach the tab strip 7 to the base tab 5. For this purpose, the Tab strips 7 from below with its two tabs 13, 14 through the mounting slots 12 inserted until the central section 15 in contact the bottom of the base tab 5 reaches. In the area of the fastening slots 12 the tab strip 7 is in each case at an angle of 90 ° upwards bent so that the tabs 13, 14 vertically to the base plate 5 upwards protrude. The sheets 3 of the stack of documents are on these tabs 13, 14 2 pushed on (Fig. 10)

Furthermore, the cover tab 6 is pushed onto the tongue 13, 14 as follows (Fig. 9). The strip-shaped cover flap 6 (FIGS. 3a and 3b) has one on the one hand Perforation 16, which consists of the two holes 17. The latter swore in Use position (Fig. 9) in the vertical direction with the holes 11 of the Base tab 5. On the other hand, another perforation 18 with holes 19 in the Cover tab 6 provided on the straight line between the Holes 17 lie within the same. The holes 19 are aligned vertically Direction with the mounting slots 12 in the base tab 5 and serve for Reaching through the tongues 13, 14 of the tongue strip 7 (Fig. 9 and 10).

The cover flap 6 has a parallel to the longitudinal line 9 within the perforation 18 Indentation 40 into which the tongue ends 13 ', 14' in assembled state are inserted (Fig. 4). Through this deepening 40 the total height of the stapling mechanism is reduced.

The profile rail parts or profile rail shafts 22, 22 'are pushed onto the cover plate 6 and then form a cover completely surrounding this. The cover tab 6 has two notches on both sides of their longitudinal edges 38 or to the End flaps 20, 20 'that widen in stages towards the cover flap. The Profile rail parts 22, 22 'each have two on the inside thereof Gradations 20, 20 'complementary steps and therefore snap when pushed from the two opposite ends of the cover plate 6 to the Notches or gradations 20, 20 '.

In addition, the cover flap 6 has one on each side parallel to the longitudinal center Bulge 21, which when pushing the Cover profile loop halves 22, 22 'by slightly arching the cover flap 6 gives more rigidity.

Furthermore, below the abutting edge 30, between the cover profile rail parts 22, 22 'an insertion stop 31 is formed on the long sides 23, which in the Insert channel 25 protrudes and with side locking elements of the cover tab 6 can also latch with the gradations 20, 20 '.

As can be seen from Fig. 9, the cover rail parts 22, 22 'in Provide the stitching mechanism in the assembled state with a perforation 33, whose holes 34 with the holes 11 of the perforation 10 in the base tab 5 and with the holes 17 of the perforation 16 in the cover plate 6 in the vertical direction aligned.

As is clear from FIGS. 8 to 10, the roughly two-part center Cover rail 8 a bracket-like cross section with two in Use position cover parts on top. With each cover part of the Profile rail 8 close on the long sides 23 bent inwards Gripping bars 24. These gripping bars each form one with the cover part Insert channel 25 for the cover plate 6 and on the top of the cover plate 6 bent tongue ends 13 ', 14'. The insertion channel 25 has longitudinal and 29 semicircular at the ends Undercut areas 26 (Fig. 10). The longitudinal end edges 27 of the Gripping bars 24 are at a distance from one another in the transverse direction, which is sufficiently large that the tabs 13, 14 and the bracket of a not shown stitching mechanism of a filing folder can step through.

On the top of each cover rail part 22, 22 'is in the range Butt edge 30 a corrugation 32 is provided (Fig. 6 and 7), the collapsed state of the cover profile rail 8 the shape of an "X" can form. This corrugation 32 facilitates the opening and handling Sliding in the cover profile rail halves. The two triangular areas 35 between the upper and lower branches of the corrugated "X" are each in one piece formed with one of the two profile rail halves 22, 22 '.

These triangular projections 35 make a seamless transition between reached the profile rail halves 22, 22 'in the closed state.

Fig. 6 shows the stapling device in the ready-to-use state. Here are the two cover profile rail halves 22, 22 'only moved so far apart that the perforation 18 with the holes 19 of the cover plate 6 and through this pulled tongue ends 13 ', 14' is visible.

To use the stapling device 1, the document stack is by means of commercially available punch with two pairs of perforations, one with the perforations 10, 16 and 33 in the base plate 5, cover plate 6 and Cover profile rail 8 match in the hole spacing. The remaining two Punch holes in the document stack 2 are in their arrangement with the inner perforations 18 in the cover plate 6 match.

For filing the stack of documents 2, the tabs 13, 14 through the slots 12 of the base tab 5 protrude from below through the perforation 18 (FIG. 9) the cover flap inserted until the base flap 5 on the underside 36 of the Document stack 2 is present (Fig. 10).

Finally, the cover flap 6 is pushed on with the two Cover profile rail parts 22, 22 'with their inner perforations 18 to the above tabs 13, 14 attached until the cover tab 6 on the Top 37 (Fig. 10) of the stack of documents 2 comes to rest. After that the tongue ends 13 ', 14' are bent inwards into the depression 40.

9 shows, the two-part cover profile rail 8 is then on the Cover flap 6 including the bent tongue ends 13 ', 14' postponed. The circumferential longitudinal edges 38 of the cover plate 6 come to lie in the undercut areas 26 of the profile rail 8. By the insertion stop 31 on the two parts of the cover profile rail parts 22, 22 'snap in both cover profile rail parts 22, 22', so that both parts on are prevented from automatically declining movement. Only with a light weight Both parts 22, 22 'can be pushed outward again from the position loosen on the cover flap 6. The insertion stop 31 and the Holes 33 in the two-part cover rail 8 aligned so that in the stop position with the holes 34 of the two-part cover rail 8 the holes 11 and 17 of the base plate 5 and the cover plate 6 in vertical Align direction. Sliding on the two cover profile rail parts 22, 22 ' otherwise facilitated by the corrugation 32, which is also clearly the Direction of insertion marked. '

The two-part cover profile rail 8 also offers the advantage that the Sides of the cover profile rail halves 22, 22 'two each other opposite sealing eyelets 42 and 43 may be formed. Fig. 11 shows the stapling device with the two-part cover profile rail and molded sealing eyelets 42 and 43 in the open state of the Cover profile rail, where the further opening movement by hitting the in protruding the undercut area 26 of the cover profile rail parts 22, 22 ' Extensions 31 on the gradations 20, 20 'of the cover plate 6 is limited.

Fig. 12 demonstrates how the closed cover rail parts 22, 22 'with their lateral eyelets 42 through which a seal 44 is provided Sealing wire are pulled together at the opposite Long side are connected. Alternatively, this is also for the sealing eyelets 43 possible.

By the outer in the vertical direction through all layers Perforations 10, 16, 33 can be the stack of documents 2 with the described Stapling device in a standardized filing mechanism of a folder or the like. be hooked in, the bracket 11, 17 and 34 of the base plate 5, grasp cover plate 6 and cover profile rail 8.
