Abstract

The system has a binder ring (1) that is brought from an opened condition, in which the ring forms a gap (10) for inserting paper goods into the ring, into a closed condition, in which the ring has no gap. The binder ring is designed as an individual ring without connecting to a binding ridge. The binder ring has a coupling unit within an area of the gap, where the coupling unit causes overlapping in the closed condition.

Description

The invention relates to a binding system for binding perforated sheet material, wherein the binding system has a binding ring, which can be brought from an open state in which it forms a gap for attachment of the sheet material to the binding ring in a closed state, in which the bindering ring does not fill a gap.

For binding a stack of sheet material, consisting for example of paper pages, it is known to punch them and then aufzustecken on a binding system. There are a variety of different binding systems. They have in common that are inserted through the perforation binding fingers, which are interconnected. The distance between the binding fingers then corresponds to the distance between the individual holes of the perforation.

From the DE 103 93 593 T5 and WO 99/14059 generic binding systems are known in which a binding ring is attached to a spine at certain intervals in each case, which consists of two ring segments. The ring segments are movable from an open state, in which they each form a gap for attaching the sheet material on the binding ring, in a closed state in which they form a closed ring. The mobility of the ring segments is ensured by hinges.

The known binding systems have the disadvantage that the number and the distance of the binding rings must match the number and the distance of the holes of the perforation in the sheet material, so that a binding of the sheet material is possible. In addition, hinges tend to fatigue and fractures.

The invention has for its object to make a binding system of the type mentioned so that sheet material can be involved regardless of how the hole is designed, in particular what number and what distance the holes have.

This object is achieved in that the binder ring is formed as a single ring without connection to a spine. The basic idea of the invention is thus to dispense with a binding spine and to provide only at least one binding ring, onto which the sheet material can be plugged, when the binding ring is in an open state. Instead of a single binding ring, the binding system can also have several such binding rings, which are then not connected to each other. Such a binding system is not only inexpensive, but also universally applicable. The Binder rings also allow it to strike the sheet material at each point so far that the exposed sides are parallel to each other and are not bent. In addition, the pages can be turned 360 °. The binding system is therefore also well suited for demonstration purposes.

It is understood that the size of the binder ring or the maximum number of sheets that can be integrated, can be determined, d. H. By correspondingly large training of the binder ring or the binder rings and very thick stacks of sheets can be involved. Accordingly, the cross section of the respective binding ring can be closely adapted to the cross section of the holes, so that the individual sheets of the sheet material can hardly move against each other when at least two binding rings are used.

The gap formation in the binder ring according to the invention can be done in various ways. For example, the binding ring can be designed as a whole flexible so that it can be bent for the attachment of sheet material from the closed state to the open state, with no hinge is present. Alternatively, it may be provided that the binding ring has a hinge, via which it is divided into ring segments, which is pivotable relative to each other via the hinge for opening and closing the binding ring. In both cases, it is advantageous if the binder ring (s) has in the region of the gap at least one coupling element which causes an overlap in the closed state. The overlap should then be such that the free ends of the binding ring can not move laterally relative to each other. In addition, fuses can still be provided, for example in the form of locking, which prevents at least one automatic opening of the binding ring or even allow opening only by destroying the binding ring.

Alternatively to the above-described embodiment can also be provided that the binding ring each having a gap forming part ring and a gap closable bridging element. In this embodiment, the binding ring receives a closed state in that the gap between the free ends of the partial ring is closed by a respective bridging element. Such a binding ring has the advantage that it does not require a hinge for producing the open state and also does not have to be so elastic that it can be bent. The partial ring and the bridging element can therefore be rigid, so that even larger amounts of sheet material can be safely integrated.

The above-described binder ring may be part of a binding system in which a plurality of such binding rings are connected to one another via a binding spine. Preferably, the binder ring should but as a single ring without connection be formed to a spine, with several such binding rings can be provided here, which are not connected to each other as individual rings.

The respective bridging element may be in the unassembled state as a loose part, i. it is then not connected to the associated sub-ring. This does not preclude connecting it to the sub-ring via a hinge which allows the bridging elements to pivot into or out of the gap.

In a further embodiment of the invention it is provided that the or the bridging element (s) each have or have a bridging piece, which is adapted to the contour of the partial ring so that it fills the Lükke flush and the contour of the partial ring to a closed binder ring continues. The aim of this measure is to obtain a binding ring after insertion of the bridging elements, which has no external discontinuities, such as protruding edges, cross-sectional changes, etc. In this way, a snagging of the binding ring in the perforation of the sheet material is avoided.

According to the invention it is further provided that the or the bridging element (s) each having at least one coupling tab and in the respective sub-ring each adjacent to the gap for each coupling tab a recess for receiving the coupling tab is formed. Preferably, the respective should Have bridging element on both sides of the bridging piece coupling tabs and be formed in the partial ring on both sides of the gap recesses for the overlapping receiving the coupling tabs. The formation of the coupling tabs in detail is possible in many ways.

The connection of the coupling tab (s) with the associated sub-ring can be done in various ways. A firm connection can be achieved in that the coupling tab is connected in each case via a latching connection with the associated sub-ring, wherein the latching connection can be designed depending on the purpose so that the bridging element is also removable again, for example, to attach more sheet material or sheet material to remove , Alternatively, it can be provided that the latching connection no longer allows a release of the bridging elements.

Also, the coupling tab (s) should - as the bridging piece - be designed so that it fills the associated recess in the sub-ring in the assembled state so that there continuation of the contour of the sub-ring, so the binding ring in the bridging element no has external discontinuities.

According to a further feature of the invention it is provided that the or the binding ring (s) on the outside and / or inside forming or forming circumferential surfaces, the extend perpendicular to the ring plane. If the binder ring is circular, these surfaces have cylindrical shape. The arrangement of such surfaces avoids that the binder ring tilts when lying the sheet material on a plane.

As the material for the binder ring (s) are mainly plastics in question, because binder rings are inexpensive to produce from this material, have a low weight and especially when the binder ring has no sharp edges, hardly cause scratches. Of course, other materials may be considered.

The binding rings are preferably formed identical to one another. There are no major restrictions on their design. First and foremost, there are circular binding rings. However, the binding rings can also be shaped differently, for example as an oval, a rectangle with rounded corners, etc.

As already mentioned above, the binding ring according to the invention can be designed so that it can not be opened again after a closing operation. This can be done by means of appropriately trained snap-in connections. However, if there is a need to remove sheets of the sheet or add more sheets to the sheet material, it is useful if the binder ring after a closing process is also apparent again.

In the drawing, the invention with reference to an embodiment is illustrated in more detail. Show it:

FIG. 1

a binding ring, consisting of part ring and bridging element, in the open state in a perspective view,

FIG. 2

the binding ring according to Figure 1 in the closed state, also in a perspective view, but rotated relative to the illustration in Figure 1 by approximately 180 °.

The binder ring 1 shown in the figures consists of two parts, namely a partial ring 2 and a bridging element 3. The partial ring 2 is circular and has a rectangular cross section with top and bottom side surfaces 4, 5, which extend parallel to the ring plane, and with inside and outside cylindrical surfaces 6, 7, which extend perpendicular to the ring plane. The side surfaces 4, 5 merge into the cylindrical surfaces 6, 7 and are connected to each other via folds 8, 9 which form chamfers.

As can be seen from Figure 1, the partial ring 2 is not closed, but has a gap 10 which is bounded by end faces 11, 12 of the partial ring 2. Adjacent to the gap 10, the partial ring 2 has stepped recesses 13, 14. In the region of the recesses 13, 14 the sub-ring 2 is penetrated in each case by a passage slot 15, 16 elongated in the circumferential direction. In each of the through slots 15, 16 extends a pair of oppositely formed at the same height latching steps 17, 18 and 19, 20, which protrude into the passage slots 15, 16.

The bridging element 3 has a T-shaped basic shape with a bridging piece 21 and coupling lugs 22, 23 integrally formed on the bridging piece 21 on both sides. On the side on which the bridging piece 21 protrudes, latching pins 24, 25 are formed on the coupling lugs 22, 23. which stand upright from the coupling tabs 22, 23 and form at their free ends locking cones 27, 28, which taper towards the free ends. Below the locking cones 27, 28, the locking pins 24, 25 of two mold blocks 29, 30 and 31, 32 flanked.

In the open state, as it results from Figure 1, 2 sheet material can be plugged onto the sub-ring by the sheet material is pushed through the gap 10 so far until the hole of a hole at the level of the end faces 11, 12 is located. Then, the part ring 2 can be rotated so that it passes through this hole. Subsequently, the bridging element 3 is moved from the position shown in Figure 1 upwards such that the bridging piece 21 in the gap 10 and the coupling tabs 22, 23 in the recesses 13, 14 border. The enforce the Latching pins 24, 25, the passage slots 15, 16, wherein the latching cones 27, 28 at the latching steps 17, 18 and 19, 20 pass under lateral compression by this. The end position of the bridging element 3 is reached when the locking cones 27, 28 are completely moved past the locking pins 17, 18 and 19, 20 and then get back their original shape. The diameter of the lower edges of the locking cones 27, 28 is then again greater than the free distance of the respective opposite latching steps 17, 18 and 19, 20, that is, the engaged state is reached.

This position is shown in FIG. From this figure it can be seen in particular that the bridging piece 21 and the coupling tabs 22, 23 are formed such that the bridging piece 21, the gap 10 and the coupling tabs 22, 23, the recesses 13, 14 completely and flush fill. The finished binder ring 1 has no discontinuity in the region of the bridging element 3, i. H. its contour corresponds in this area of the contour of the partial ring 2 in the rest, d. H. the binding ring 1 is rotationally symmetrical circular.

The passage slots 15, 16 make it possible to exert on the free ends of the locking cones 27, 28 compressive force in the direction of the coupling tabs 22, 23 to push them past the latching steps 17, 18 and 19, 20 down and thus the bridging element 3 to push down from the position shown in Figure 2.

In this way, the binding ring 1 can be opened again, for example, to remove it from the sheet material, to remove individual sheets of the sheet or to add sheets to the sheet material. Subsequently, the binding ring 1 can be closed again by the handling described above.
