Abstract

A clip report cover for unpunched documents (16) comprises a U-shaped clip element that is formed by a retaining piece (7), a connecting rib (8), and a clip piece (9) and extends across the clip report cover in the swiveled-in or inserted state. The clip edge (12) of the clip piece (9) is lowered beyond the clip plane (19) of the retaining piece (7), preferably into a clip slot (14) configured in the retaining piece (7) or a retaining piece groove such that the documents remain securely clamped even after reducing the stack height.

Description

The invention relates to a clamping folder for unperforated documents, consisting of a folder bottom and a folder cover and the folder bottom and lid pivotally or slidably cross, substantially U-shaped, elastic clamping element, which acts on the folder bottom holding leg and one on this via a connecting web having elastically held, to the front edge of the retaining leg towards lowered clamping leg having a clamping edge.

Clamping folders or binders for loosely inserted, unperforated documents usually consist of a folder bottom and a folder cover, which are connected to one another on a longitudinal side via a fold. An inserted into the clamp or binder paper stack is clamped with a in the middle of the binder and near the fold movably mounted, substantially U-shaped clamping element made of elastic material that engages over the outer surfaces of the binder, between the bottom and lid, and Although without the inserted paper is damaged in an undesirable manner.

The document FR 1 456 927 A discloses a clamping element with a clamping leg and a holding leg, where the terminal card of the clamping leg protrudes to improve the clamping action in a starting position in a groove of the retaining shank.

At one of the EP 0 609 568 known clamping flap comprising the elastic material, such as plastic or sheet metal, existing clamping element has a substantially flat retaining leg which is pivotally held at its upper end about a vertical axis on the folder bottom, and integrally formed on the longitudinal side via a connecting web to the retaining legs, resiliently formed clamping leg. The holding leg is formed longer than the clamping leg, wherein at an upper extended end of the retaining leg a Opening is formed to the pivotal attachment to the folder bottom. In the swung-in state of the clamping element, the folder bottom and the folder cover and the documents located therebetween are jammed between the holding and the clamping legs. After swinging out, the clamping element is no longer in engagement with the bottom and the lid of the clamping flap, so that the paper stack or parts can be removed from this or new documents can be added or the withdrawn paper stack can be replaced by a larger or smaller ,

However, the known clamping flaps with pivotable or slidable clamping element are disadvantageous in that an already used for a stronger paper stack clamping flap for fixing a less strong paper stack can not be satisfactorily used again, since the clamping force of the clamping element or the elastic clamping action of the material has since subsided and the clamping opening between holding and clamping legs has widened in the meantime and thus can slip out the documents. A reduction of the nip width is a difficult in this case handling of the clamping element.

The invention has for its object to further develop a clamping folder with pivoting clamping element so that even with repeated use with reduced paper stack thickness secure jamming of the document is guaranteed and beyond easy handling of the clamping member is guaranteed.

According to the invention the object is achieved with a trained according to the features of claim 1 clamping flap.

In a generic clamping flap, the basic idea of the invention is that the clamping edge of the clamping leg is lowered below the clamping plane of the holding leg, that is, the nip width has a negative value, so that ensures a sufficient clamping force even with respect to the previously clamped stack of documents stack height reduced is. The negative nip width is advantageously achieved in that the elastic clamping leg dips with its clamping edge in a holding leg formed in the clamping slot or in a rounded Halteschenkelnut, so that the paper stack not only frictionally, but due to a paper stack in the clamping slot or in the retaining leg groove formed small Deepening or denting is also held positively. A pivotally formed clamping element is preferably articulated at its lower end to the clamping flap or the folder bottom, so that the clamping element is arranged ergonomically advantageous and easily movable even with the invention improved clamping action with one hand. However, the clamping element can also be held pushed onto the clamping flap.

Advantageous developments and expedient embodiments of the invention will become apparent from the following example described embodiment of a clamping binder and the dependent claims.

The clamping flap 1 comprises a folder bottom 15 and a folder lid 3 connected to its left edge in the drawing plane via a fold 2. From the folder cover 3, a window 4 emerging from the fold 2 is cut out. In the region of the window 4, a clamping element 5 is pivotally mounted about a pivot point 6. The substantially U-shaped clamping element 5 consists of a holding leg 7 and an integrally connected thereto via a connecting web 8, to the holding leg 7 towards arched clamping leg 9. The clamping element 5 is made of elastically deformable hard plastic. The holding leg 7, whose inner surface is opposite to the outer surface of the folder bottom and which is formed longer than the clamping leg 9, has in its beyond the clamping leg lower portion 10, a bore 11, via which the clamping element 5 by a rivet (not shown) with the folder bottom 15 is pivotally connected. In the in Fig. 1a illustrated pivoted position documents can be inserted or removed. In the in Fig. 1b reproduced unfolded representation of the clamping flap 1, the clamping element 5 engages over the folder bottom and one after cutting the window 4 in this remaining, connected to the fold 2 tab 21. An inserted into the clamping folder 1 stack of documents 16, in the window 4 also from the Tab 21 is covered is thus clamped by the resiliently formed clamping element 5 in the eingeschwenktem state with the free clamping edge 12. When the clamping element 5 is pivoted away in the direction of the arrow 13 from the fold 2, the records are free in the clamping flap 1 and can be removed in whole or in part.

Even with a significant reduction in the height of the stack of documents, the clamping action of the pivoted-back, the folder bottom and the stack of documents (in addition to remaining in the window 4 tab 21) cross-clamping element 5 due to its - explained below - special training still obtained. In the holding leg 7 is how the FIGS. 2 to 4 show a parallel to the front edge extending, the clamping edge 12 opposite clamping slot 14, in which the clamping edge 12 according to Fig. 2 can dip in pivoted state of the clamping element 5, so that the clamping gap width can assume a negative value "a" and thus the clamping effect can be increased. Because the folder bottom 15 and the stack of documents 16, such Fig. 3 shows, lie above the clamping slot 14 and cover this, presses the clamping edge 12 the stack of documents 16 together with tab 21 slightly into the clamping slot 14, that is, under the clamping plane 19 of the retaining leg 7, so that on the one hand increases the clamping action and the records are also not only frictionally held, but is anchored in a slight recess 17 and a positive fit. Due to the combination of frictional and positive fixing a reduced in further use in the amount of documents stack 16 is still securely held in the clamping flap 1.

For easy handling of the clamping flap while the easy operation of the clamping element 5 due to the underlying pivot point 6 is important. The clamping element 5 is arranged ergonomically advantageous due to the provided at the lower end of the retaining leg 7 fulcrum 6 and therefore can be easily operated with a hand movement. In addition, the clamping edge 12 of the clamping leg 9 and the front edge 18 of the holding leg 7 are rounded like a bead to facilitate the mobility of the clamping element 5 and to create a paper-preserving, well-rounded recess 17 in the stack of documents 16. In addition, a part of the pivot point 6 facing end side of the clamping leg 9 mouth-like (insertion jaw 22) is opened, so that the clamping element 5 can be easily pushed during pivoting.

The FIGS. 5 and 6 show yet another embodiment of a pivotally designed clamping element 5, in which in the holding leg 7 - instead of the clamping slot 14 - a retaining leg groove 20 is formed, so that the clamping edge 12 of the clamping leg 9 can be lowered below the clamping plane 19 of the retaining leg 7. In the sectional view according to Fig. 6 is the well-rounded design of the clamping edge 12 and the retaining leg groove 20 and the front edge 18 of the retaining leg 7 recognizable.
