Description

The invention relates to a Bindeclip for stack-like holder punched leaves.

On the market a variety of books, folders, folders and the like are known, which allow an individual compilation of individual pages. In the so-called spiral wire binding or hot melt adhesive method, however, the subsequent insertion of new pages is no longer possible. For such purposes, for example, ring binder or ring binder are used. In addition, there are a variety of Bindeclips that interact with pre-cut holes in the leaves. Furthermore, clamping strips and so-called clamping folder binders are known, which pinch the binding without it must be perforated, but this leads to a margin loss of up to 20 mm and more and usually does not represent a real secure bond. Also aesthetically, here are often compromises to be accepted. An overview of the various binding systems can be taken from the publications identified in a search, which are listed below:

From the CA 2 700 954 A1 Furthermore, a Bindeclip with two hingedly interconnected parts is known, being provided on a part of a flexible pin for inserting and removing the perforated sheets. The pin cooperates in the closed position with a bore in the other part, wherein the pin projects with its hook-like end through the hole and hooked there. However, this known Bindeclip has the disadvantage that only a few leaves can be supported and also no sufficient grip is ensured to prevent twisting of individual sheets around the pin.

In the DE 100 10 186 A1 Therefore, a device for stack-like mounting of perforated sheets is disclosed which has two hingedly coupled parts which release in its open position connected to one of the two parts pin, which serves for inserting and removing the perforated sheets and wherein the inserted sheets in the closed position the two parts are secured by the pin comes with the other part in releasable closing contact. One of the two parts further comprises a trained parallel to the hinge axis stop bar for an edge region of the inserted leaves, wherein the length of the stop bar is greater than their distance from the pin. The stack-like mounting of sheets is carried out in this embodiment in that initially the sheets are provided with a distance to an edge region of the sheets with a hole, wherein the distance to the edge region corresponds to the distance of the pin to the stop bar of the device used or slightly larger. Then, the blades are placed with the edge portion on the stop bar of the device, and the pin of the device is passed through the perforation of the leaves. Finally, the device is closed. By an exact dimensioning of the distances, the sheets can be held against rotation. However, the insertion of the leaves in this device is somewhat cumbersome when the hole distance from the edge does not exactly match the distance of the pin to the stop bar.

The invention is therefore based on the object, the Bindeclip for stack-like support perforated sheets to further develop that on the one hand a twist-proof mounting of the perforated sheets is possible and on the other hand to facilitate handling when inserting the leaves.

According to the invention, this object is solved by the features of claim 1.

The binding clip according to the invention for punch-like holding of perforated sheets has two parts coupled to one another via a hinge joint, which in its open position release a pin connected to one of the two parts, which serves for inserting and removing the perforated sheets, and wherein the inserted sheets are in the closed position are secured by the pin comes into contact with the other part and at least one perpendicular to the hinge axis of the hinge joint aligned stop bar is provided on at least one of the two parts for an edge region of the inserted sheets.

In the experiments on which the invention is based, it has been shown that a torsion-resistant holder can also be ensured with a vertically formed stop bar. Thereby results in the advantage that the contact area between the stop bar and edge region of the sheets to be inserted is significantly reduced and a possibly slightly too large trained hole spacing significantly simplifies the insertion of the leaves against a parallel to the edge region aligned stop bar.

Further embodiments of the invention are the subject of the dependent claims.

The rotation and the handling can be further improved especially if the aligned perpendicular to the hinge axis stop bar is sharp-edged in the contact area with the edge portions of the leaves. In this way, the stop bar cuts slightly into the edge region of the leaves, which on the one hand supports the rotation and on the other hand, the leaves in the stop bar are not bent upwards when the hole spacing is slightly too large.

According to a preferred embodiment, at least two spaced-apart stop strips are provided for the edge region of the inserted sheets. Furthermore, the part which carries the at least one stop bar, two L-shaped interconnected legs, wherein the at least one stop bar is formed on one of the two legs. It is possible that the two legs are different lengths and the stop bar and the hinge joint are arranged on the shorter leg.

For the closed position, a suitable closing mechanism is provided, which is preferably designed so that the pin connected to one of the two parts comes into contact with at least one closing hook arranged on the other part. The locking hook and the pin can each have negatively shaped contact surfaces which come into contact with each other and thereby ensure a particularly secure cohesion. For most applications, it is advantageous if the Bindeclip is designed for multiple closing and opening, it is provided according to an embodiment of the invention that the pin or the locking hook is flexibly supported on the corresponding part and so a relative movement of the two, the closing contact ensuring elements is possible. Preferably, the pin is formed of at least two relatively movable pin elements. The opening of the closing contact can be designed so that an opening by hand or a simple tool, such as a pen is possible.

Tying clips are usually designed for a certain number of perforated sheets. Of course, then less leaves can be inserted. However, this often means that the Bindeclips is relatively loose and some uncertainty could arise over whether a sufficient grip is still guaranteed. Due to the sharp-edged, vertical stop bar the range of motion of the inserted leaves is already relatively limited. In order to provide a further improvement in this regard, in addition to the vertical stop bar also a perpendicular to the stop bar aligned pressure bar can be provided, which comes into contact with one side of an inserted sheet. In this case, in particular two perpendicular to the stop bar aligned Andrückleisten be provided which limit the two aligned perpendicular to the hinge axis sides of the two parts and thereby come into contact with the lowermost sheet. Again, a rather sharp-edged design of Andrückleiste is appropriate.

Furthermore, it can be provided that the part carrying the pin is provided with an integrated eyelet eyelet. In this way, held together with two Bindeclips sheets can be stored by means of Abheftösen for example in a conventional ring or file folder. In addition to the use of individual binding clips, it is, of course, also possible within the scope of the invention to design a device for stacking perforated sheets with two binding clips in accordance with the above features, wherein the two binding clips are connected to one another via at least one connecting element.

While the tie clips described above are a quick and easy way to bond multiple apertured sheets together, there will be many applications where the tie clips are used in conjunction with a folder in which punched sheets are then deposited. The folder or the outer envelope can be configured in various forms. The binding clips are then held, for example, in corresponding recesses of the folder in such a way that the binding clips are, on the one hand, connected to the folder and, on the other hand, make it possible to insert and remove perforated sheets and to close or open the binding clips.

When closing the Bindeclips is usually the part that does not carry the pin, folded around the hinge joint and then covers the pin in the closed position. The edge of this part farthest from the hinge joint also defines the edge area of the inserted leaves, which is no longer visible when turning over the individual leaves. To this area To keep as narrow as possible, is provided according to a particular embodiment of the invention that the coming into contact with the pin part of the binding clip in its distal end of the hinge joint is adapted to the outer contour of the pin and thus an extension and a conclusion of the pin 4 forms. The inserted leaves can at least partially slip over the pin when turning over and are then held only in the much narrower area between the pin and hinge joint between the two parts of the Bindeclips. The area remaining hidden by the turning is thereby significantly narrower.

Further embodiments of the invention will be explained in more detail with reference to the following description of some embodiments.

That in the 1 and 2 dargstellte first embodiment shows a Bindeclip 100 sheets punched in a stack with two with a hinge joint 1 coupled parts, namely a lower hinge part 2 and an upper hinge part 3 , which in its open position one with the lower hinge part 2 connected pins 4 release, which serves for inserting and removing the perforated sheets. The pin 4 here consists of a rigid pin part 4a and a flexible, at its end hook-shaped pin part 4b ,

In the closed position of the binding clip 100 comes the pin 4 with its hook-like, flexible pin part 4b with one on the upper hinge part 3 trained closing hook 3a in close contact ( 2 ). The flexible pin part 4b is in the in 2 shown biased closed position, but can at its hook-like end of the closing hook 3a pushed away to the upper hinge part 3 release. The upper hinge part 3 is therefore in the area of the flexible pin 4b with a recess 3b provided, in which the flexible pin part 4b protrudes. To open the binding clip 100 becomes the flexible pin part 4b with a finger or a suitable tool, such as a ballpoint pen, from the locking hook 3a in the direction of the arrow 20 pushed away. The locking hook 3a and the hook-like end of the flexible pin member 4b expediently interact with each other via negatively shaped contact surfaces. In this way, unintentional opening of the binding clip can be largely avoided.

In the 3 to 5 is a binding clip 101 represented according to a second embodiment, which only by an additional Abheftöse 5 different from the previous embodiment. Therefore, the same reference numerals have been used for the otherwise same components. The pickup loop 5 is sized so that one with two tie clips 101 held together stack of leaves in a conventional ring binder or a folder with a ring mechanism can be stored.

From the 2 and 4 are also two perpendicular to the hinge axis 1a of the hinge joint 1 aligned stop strips 6 . 7 recognizable, which come into contact with an edge region of the leaves to be inserted. The distance a between the front end of the stopper power 6 . 7 and the facing end of the pin 4 or the fixed pin part 4a is to be adapted to the hole spacing of conventional holes such that the distance a corresponds to the hole spacing or is slightly smaller. In this case, the stop bars 6 . 7 , which are preferably sharp-edged in the contact area, cut something in the leaves to be inserted, whereby an additional rotation is ensured. From the 2 and 4 It can also be seen that the lower hinge part 2 L-shaped, wherein the shorter leg 2a the stop strips 6 . 7 and the hinge joint 1 wears while on the longer thigh 2 B the pin 4 is trained.

The longer thigh 2 B of the lower hinge part 2 also comes with two side pressure strips 8th . 9 limited. The first in the binding clip 100 . 101 to be inserted sheet comes with its underside on these Andrückleisten 8th . 9 to lie. The Andrückleisten are therefore formed in contact area also comparatively narrow or sharp. Through this training, the Andrückleisten press 8th . 9 with a maximally filled binding clip, insert something in the stack of perforated leaves. When some leaves are removed, the pressure strips become 8th . 9 pressed accordingly less in the stack, but still there is still a firm hold of Bindeclips on the inserted stack available. Only when significantly fewer leaves are inserted, the support of the leaves in the direction of the pin is slightly lower. Due to the sharp-edged stop strips, but also in this case, a firm hold of Bindeclips on the stack of inserted leaves is present.

6 and 7 show a binding clip 102 with a locking hook 3.1a and a cooperating, flexible pin part 4.1b which are arranged rotated by 90%. Since the Bindeclip can naturally be made relatively small and the recess 3.1b in the upper hinge part 3.1 is still smaller, an actuation of the flexible pin member according to the embodiments of the 1 to 5 may cause some problems with your hand. Therefore, it will be expedient to use an aid, for example in the form of a ballpoint pen. When Bindeclip 102 according to the 6 and 7 It is also conceivable that the upper hinge part 3.1 relative to the lower hinge part 2.1 in the direction of the arrow 10 is pressed, thereby releasing the make contact. Since the binding clip is preferably made of plastic, a sufficient elasticity is present, which allows such a twist for releasing the closing contact.

8th shows a side view of one with a Bindeclip 100 held together pile of perforated leaves 11 , wherein a part of the leaves is opened. You can see that from the hinge joint 1 opposite end of the upper hinge part 3 an edge 3c forms around which the perforated leaves 11 be bent over. The non-visible edge area b of the perforated sheets 11 is therefore slightly larger than the length of the upper hinge part 3 ,

The in the 9 to 11 illustrated binding clip 103 allows for a reduction of this non-visible edge area of the perforated sheets 11 by a special embodiment of the upper hinge part 3.2 , The peculiarity is that of the pin 4 covering part 3.2d of the upper hinge part 3.2 to the outer contour of the pin 4 is adjusted and thus an extension and a conclusion of the pin 4 forms. When turning over individual leaves they can then out of the pin 4 be pulled out and then bend only in the area of a shoulder 3.2e , The resulting difference is by comparing the 8th and 11 immediately visible. Of the hidden edge area of the inserted leaves is in the variant of 11 much narrower.

• A: Abstand zwischen Loch- und Papierrand der eingelegten Blätter 11
• B: Lochdurchmesser
• C: Ausdehnung des Zapfens 4
• D: Radius, den das unterste Blatt beim Aufschlagen ausführen würde
• E: Radius, den die oberste Seite beim Aufschlagen ausführen würde
• H: Höhe des Stapels der eingelegten Blätter 11

In 12 Below, some information on the dimensioning of the in 10 shown Bindeclip 103 specified. Mean

• A: Distance between hole and paper edge of the inserted sheets 11
• B: hole diameter
• C: extension of the pin 4
• D: radius that the lowermost sheet would execute on impact
• E: Radius that the top side would perform when hit
• H: height of the pile of the inlaid leaves 11

In this embodiment, it is useful if the height of the stack is about as large or smaller than half the diameter of the hole in the leaves. Furthermore, it has proved to be useful when the pin 4 is moved inwards slightly out of the center and, if necessary, additionally executed in an oval shape. To allow the smaller radius D, the pin can also be flattened at the top. The curve D also gives the shape of the part 3.2d of the upper hinge part 3.2 before, so that the lowest sheet can still be fully opened.

Although a perforated stack of sheets can only be held together with two of the binding clips described above, the product thus formed can be made aesthetically pleasing in a simple manner by forming an envelope with an envelope or simply by inserting a back cover or front cover. Various embodiments will be explained below.

Such is the pile of punched leaves 11 according to 13 with a back cover 12 Mistake. So that made of possibly stronger material back cover 12 can be handled, for example, in the bending area grooves 13 intended.

In the embodiment according to the 14 and 15 is an envelope 14 provided from a front book cover 14a , a rear hutch lid 14b and a spine 14c consists. For the two Bindeclipse are on the back cover 14b near the spine recesses 15 intended.

16 shows a variant with an envelope 14.1 which is inlaid like the punched leaves.

In 17 and 18 becomes a variant with an envelope 14.2 shown for a tie clip 101 with eyelet 5 suitable is. When the envelope is closed, the front cover will cover 14.2a the Bindeclip up to the Abheftöse 5 completely off from above. For the binding clips 101 are in the back cover 14.2b and in the spine 14.2c corresponding recesses 15.2 intended. Furthermore, in the front buckle 14.2a a viewing window 21.2 incorporated.

Also in the embodiment according to in 19 and 20 The binding clips are made from below through recesses in the back cover 14.3 stuck through it. Furthermore, in the area of the front lid 14.3a recesses 16.3 intended. In the closed state of the folder according to 19 occur the upper hinge parts 3 the binding ellipse through the recesses 16.3 therethrough. This results in a very flat folder. An optional viewing window 21.3 , completes the portfolio.

21 . 22 show a 3-ply envelope 14.4 wherein the clip is hung at one end of the three layers like a sheet to be inserted in the binding clip.

Although the binding ellipse can be formed individually, it is of course also possible to have several, in particular two binding ellipses via at least one connecting element 19 to connect with each other ( 23 ).

In the 24 and 25 Finally, there is a folder with an envelope 14.5 shown in which the recesses 15.5 not centered, but arranged offset upwards. This results in the possibility of turning the leaves so that the leaves are visible at least in the lower area to the left edge.
