Description

Ring binder with ring clasps and

Insert sheets

The invention relates to a ring binder with a plurality of

of ring clasps and insert sheets, which are with along 20

arranged on the binding edge, for the passage of the

Ring staples are provided with openings for receiving them, which, like the ring staples, are arranged symmetrically with respect to an axis of symmetry running perpendicular to the binding edge across the middle of the sheet. 25

Ring binders of the type mentioned are known in a variety of forms, e.g. as calendars, workbooks and especially as so-called schedule books.

The ring binders on the market, especially

other timetable books, differ from each other in the same format mainly in the spatial distribution of the ring clips and openings in the insert sheets. A particular problem with the ring binders of the type mentioned, which are known from the state of the art, is that the arrangement of each ring binder

ing of the ring clips on the one hand and the receiving openings in the insert sheets on the other hand in
are in such a relationship that the insert sheets only fit into one ring binder, which has the corresponding arrangement of the ring clips. As a result, it is not possible to insert insert sheets from one system into the ring binders of the other systems. But this is precisely what is possible in many

t
This is desirable in some cases, for example when certain insert sheets with a special print are to be filed in ring binders with differently arranged ring clasps.

It is therefore the object of the invention to further develop the ring binder of the type mentioned at the outset in such a way that its insert sheets can also be inserted into ring binders with
differently arranged ring binder clips without affecting the proper fixation of the insert sheets in the ring binder.

To solve this problem, the invention proposes, starting from a ring binder of the type mentioned at the beginning, that the receiving openings in the insert sheets have the form of elongated holes widened in the longitudinal direction of the binding edge, with at least one ring clip above the axis of symmetry being in contact with the upper or lower hole bearing of at least one elongated hole and, below the axis of symmetry, the ring clip arranged symmetrically to the first-mentioned ring clip being in contact with the opposite hole bearing of the elongated hole symmetrical to the first-mentioned elongated hole.

The invention makes it possible to provide the receiving openings in the insert sheets in such a way that they can be used for several different ring clamp arrangements.

are reversible. In each individual case, the fixing is carried out on at least two opposing hole reveals of two symmetrically arranged elongated holes.

In order to further increase the number of possible adaptations to different ring staple systems, a particularly advantageous development of the invention provides that the elongated holes arranged above and below the axis of symmetry are of different lengths and have different distances from one another in the longitudinal direction of the stapling edge.

An embodiment of the invention is explained in more detail below with reference to the drawing.

In Fig. 1, the dust jacket of the ring binder is designated in its entirety with the reference number 1. This dust jacket is in the area of the spine

^ou provided with a plurality of ring clips 2, which in a known manner each consist of two clip halves that are spring-loaded against each other. A plurality of insert sheets 3 are inserted into the protective cover 1, which are provided with

Receiving openings 4 are provided for the passage of the ring clamps 2.

In Fig. 2, such an insert sheet 3 is shown in plan view. The insert sheet 3 has an axis of symmetry 5 in the middle of the sheet. The receiving openings 4 are each designed as elongated holes extending in the direction of the binding edge and are arranged symmetrically with respect to the axis of symmetry 5. In the exemplary embodiment, the receiving openings designed as elongated holes are of different lengths and also have different distances from one another.

Fig. 3, 4 and 5 illustrate how the arrangement and design of the receiving openings shown in Fig. 2 enables adaptation to different ring clamp arrangements. In all cases, the ring clamps 2 are also arranged symmetrically with respect to the axis of symmetry 5.

In order to ensure a perfect fixation of the appendix 3 despite the possibility of adaptation to the different
In order to ensure the safety of ring clamp systems, at least one ring clamp 3 is always located above the axis of symmetry 5 on the upper or lower hole bearing of at least one elongated hole and below the axis of symmetry 5 the symmetrical to the first-mentioned

set hole bearing of the long hole symmetrical to the first mentioned long hole.

In the embodiment according to Fig. 3, above the axis of symmetry, all three ring clamps 2 rest on the upper hole bearing of the receiving openings 4. Below the axis of symmetry 5, on the other hand, all ring clamps 2 rest on the lower hole bearing of the receiving openings 4. In the embodiment according to

Fig. 4 only the two of the symmetry axis 5 are at 35

next lying ring clamps 2 to the respective

inner hole bearings of the symmetry axis 5 at
The insert sheet is then clamped onto the ring clamps 2 and secured against vertical displacement relative to the ring clamps 2.

In the embodiment of Fig. 5, the two outer ring clamps rest above the axis of symmetry 5 on the inner hole bearings of the two upper receiving openings 4. Below the axis of symmetry
the two outer ring clamps 2 rest on the opposite hole reveals of the receiving openings 4 of the insert sheet 3 located there.

In all three embodiments, the sheet fixation of the insert sheet 3 to the ring clamps 2 is indicated by arrows 6.

As is readily apparent, theoretically, with the arrangement and design of the receiving openings 4 shown in Fig. 2, further

Constellations of the ring clips are possible without affecting the perfect fixation of the insert sheet.
