Fastening device for a binder

A device for fastening labels to binders which exhibit slots arranged in pairs at a mutual distance from each other for receiving end sections of label holders, and for firmly locking the end sections in the slots. The label holder is pocket-shaped, is flexible, and exhibits rows of recesses along lateral edge sections opposing each other. Hook-shaped locking elements distributed in rows are received inside the slots. The row of recesses and locking forms formed are adapted to each other in terms of shape for lockable receiving, interacting in pairs, of the respective locking elements in a suitable recess after insertion of the respective label end sections in a suitable slot.

The present invention relates to a device for fastening a label to a binder which exhibits slots arranged in pairs at a mutual distance from each other for receiving end sections of label holders, and locking the same firmly therein.

BACKGROUND

This application claims priority from Sweden Application No. 0702754-3 filed on Dec. 12, 2007, which is incorporated here by reference.

There are many different devices for carrying labels on binder spines. Normal such devices are riveted pocket-shaped plastic pockets in which loose labels containing different information can be inserted. It sometimes happens that such label pockets loosen from the binder and the binder is then destroyed and must be scrapped, since no further on information is available on the content of the binder. Metal rivets suffer from the drawback that that they are able to soil adjacent binders, desks or any other object against which the binder is in contact. This applies particularly if the metal consists of aluminium, which blackens adjacent objects.

Other solutions are rigid, transparent plastic discs arranged so that can be inserted, with the respective angled edges, in suitable slotted recesses on the side of the binder, thereby retaining it in position with a receivable information label inside the same. These label holders risk being damaged or loosening easily from the binder by catching, or when the binder is opened. The action of sunlight may also impair its durability and fastening capacity.

SUMMARY

The principal object of the present invention is therefore primarily to solve the above-mentioned problems, among other things, by means of simple means that operate satisfactorily.

The object is achieved by means of a device according to the present invention, which is characterised mainly in that the pocket-shaped label holder is flexible and exhibits recesses in rows along opposing lateral edge sections, in that hook-shaped locking elements distributed in rows are received inside the slots, the row of recesses and row of locking elements being adapted to each other in terms of shape for the lockable receiving, interacting in pairs, of the individual locking elements in a suitable recess after insertion of the respective label lateral edge sections in suitable slots.

DETAILED DESCRIPTION

A device1constructed according to the present invention, which is designed for fastening labels2to binders3which are provided with slots4arranged in pairs at a mutual distance A from each other for receiving end sections5,6of label holder7, and locking the label holder7firmly therein, incorporates a pocket-shaped label holder7, which is flexible and which exhibits recesses11, arranged in rows10, along lateral edge sections8,9opposing each other. Hook-shaped locking elements12,14distributed in rows13,15are received inside the slots4. In this case row10, with recesses11and the row formed,13,15, with locking elements12,14, are adapted to each other in pairs, in terms of shape, for receiving respective locking elements12,14in a suitable recess11, lockably interacting in pairs, after insertion of the respective lateral label edge sections8,9in a suitable slot4.

The hook-shaped locking elements12,14exhibit a shape that inclines from one side12A,14A of the same, and from the other side12B,14B a transverse shape or shape inclined in the opposite direction, when label holder7provided with a recess is inserted, pass in one direction50, but continue to retain label holder7in the opposite direction60.

According to the invention hook-shaped locking elements12,14are alternately located on the laterally located walls17,18of the slots, wherein one wall18is essentially parallel to the rear angled side section19of the folding side20of the binder, whose weakened central section21forms folding elements for the side20. The other wall17is formed by a laterally displaced parallel angled part.

In each locking row13,15are located at least three locking elements12and14respectively on either side of the slot4.

The locking elements12,14preferably exhibit straight locking edges22so that the locking is rendered distinct and equal along its entire height and width.

Label holders7are in turn formed by transparent plastic material, which can be produced in long lines by welding plastic films and punching to the desired shape. They can be provided with square-shaped recesses11in rows10along sealed lateral edges23and with transverse bottom sealing24, and with opening25located at the top for insertion of a written or printed cardboard label26, etc. for the binder3in question.

Along the rows10, with recesses11, the label holders7exhibit connections27, e.g. welds in the form of rows28. These are designed to form guides for inserting label26in label holder7. For simple changing of label26on binder3, label holder7exhibits bottom recess29, which opposes insertion opening25of the respective label holders and is located in the centre of label holder7.

When pile3is folded fully up, as shown inFIG. 7, for example, label holder7is foldable either with or against folding element21of the binder spine provided with central elements.

The design and operation of the invention should be clearly evident from the above description and from what is shown in the drawings.

The method for fastening label holder7can be clearly understood on the basis of drawingFIGS. 2-3and5-7. The insertion of label holder7and its respective lateral sections7A,7B is kept in the fully folded-up position with binder spine side20in the position such as that shown inFIGS. 5-7. Locking elements12,14, distributed alternately in the vertical direction, are received by suitable recess11in the label holder, so that locking elements12,14in fastening position I cross each other, viewed in the vertical direction, i.e. locking elements12,14in a row are distributed12,14,12,14, etc. in the example shown, where seven rectangular recesses11are arranged. If a label is required to be replaced, the old one is poked through recess29in the bottom of label holder11, but if label holder11is required to be changed, the old one must first be pulled off.

The invention is not of course limited to the embodiments described above and shown in the attached drawings. Modifications are possible, particularly in terms of the design of the different parts, or by using an equivalent method, without departing from the protective scope of the invention, as defined in the patent claims.
