The invention concerns the method of folding of the binding device from paper and a paperclip of a common type, which slides to one end of the semi-rigid folding paper, which is composed of individual planes mutually separated by parallel folds that enable the movement and folding of the band of paper.

Background Art Paperclips are known, in the most frequently used form composed of wire formed into a long and a short loop overlapping each other. Paperclips or staples may cause damage to papers bound by them.

A certain improvement is represented by a solution described in the Czech patent application PV 2013-96 with a French priority 1994 from a corresponding publication of international patent application WO 95/00018, where a folded label on a paperclip is described. The label is manufactured from flexible material, e. g. from sticky tape, PVC and similar material and is composed of four planes, joined together by three seams. The parallel seams are arranged between the first, second and third planes and there is a fourth seam arranged perpendicular to them, situated between the third and fourth planes. The fourth plane is situated perpendicular to the mutually connected first, second and third planes.

The procedure for folding this label is that the first plane is first folded towards the second, the third is then folded towards the first plane lying on the second, so that the fourth and last plane, after it is folded perpendicularly to the third plane, ensures the joining of the label with a paperclip.

An advantage of this label is the joining of several sheets. A disadvantage is that a great deal of waste can be expected in manufacture, because each plane of the label has a different length, breadth and rounding and the fourth plane is situated perpendicular to the other three.

A further improvement is represented by the US patent 5,870,802, a priority from 1997, in which is described a binding paper clip, consisting of a band of semi-rigid folding material and a paperclip. The band is composed of four planes, arranged in a row and creating a continuous band, and is divided by parallel seams or folds.

An advantage is the limitation of damage to bound papers. A disadvantage is the complexity of folding, especially in the final phase, in which the second end tucks with relative difficulty into the groove created between the paperclip and the first folding of the band, which can result in the disturbance of the last plane at the second end. In the event of an attempt at further use of the paperclip, upon its removal from the paper band, in all likelihood a deformation or breaking of the last plane, or the deformation of the paperclip ill occur.

Summary of the Invention The above stated disadvantages of the existing technology are rectified or limited by the binding device from paper and a paperclip according to this invention, the basis of which depends on the fact that the band of semi-rigid paper consists of at least five planes, arranged in a row along the length of the band of paper and mutually separated by at least four folds arranged in parallel.

The main advantage of this invention is that a cheap and easily manufactured binding device is acquired, of an overall simple appearance. It is a paperclip completely covered by paper with clasping abilities that exceed those of a standard paperclip even in its extreme size. The possible uses of common paperclips are thus expanded. The binding device according to the present invention prevents the damage of joined loose leaves by nicks and scratching and allows for repeated use. This type of binding device simplifies the folding of the paper band in the final phase in sliding the fifth and fourth planes towards the groove and simplifies its unfolding and separation from the paperclip. The fifth and last plane is not damaged by folding.

The five planes constitute the optimal number for folding, whereby the rectangular shape of the paper band allows for the waste-free usage of paper material. It is advantageous for standard paperclips of all sizes and for the corresponding optimal folding of the rectangular band of paper that the first plane has a length, in the sense of the length of the paper band, corresponding to the length of the shorter loop of the paperclip, whereby the shorter loop of the paperclip in the binding device ends at the first fold between the first and second planes. The third plane then has a length, in the sense of the length of the paper band, corresponding with the length of the longer loop of the paperclip, whereby the longer loop of the paperclip ends at the third fold between the third and fourth folds.

So that it is possible to slide the standard paperclips easily and to simplify the folding of the paper band, it is advantageous that the first plane be of a length lesser than that of the second, whereby the length of the first plane and the length of the second plane is lesser than that of the third plane, whereby all lengths are considered in the sense of the length of the paper band. Advantageously, the sum of the lengths of the fourth and fifth planes is less than that of the third plane, whereby all lengths are considered in the sense of the length of the paper band, which allows for the paperclip to slide completely inside and be covered by the folded paper.

It is also advantageous that between the first and fifth planes a V-shaped groove is formed for the easy gripping of the bound sheets of paper.

It is also advantageous when the surfaces of the planes on the outer surface of the binding device are printed, allowing for the expanded use of the binding device, which thus becomes a cheap medium for advertising, marketing, promotion, classifieds, decoration, messages and information for users, such as company logos, company addresses, telephone and fax numbers, e-mail addresses and websites.

This binding device is easily created by means of folding of a paper band with a paperclip according to this invention, the basis of which rests on the this, that the paperclip is first slid onto the first plane by means of its shorter loop in a direction perpendicular to the first fold, following which the first plane with the paperclip is folded across the second first fold to the second plane, which is folded across the next second fold to the third plane, by which the folding of the paper band is completed from one side up to the third fold and the paperclip is situated with its longer loop inside this folded paper between the first and third planes. Subsequently, the paper band is folded from the second opposite end, whereby the outer fifth plane is then folded across the fourth fold to the fourth plane and then the free end of the positioned fifth plane slides inside between the longer loop of the paperclip and the first plane as far as the third fold, which completes the last folding, upon which a V-shaped groove is formed between the first plane on one side and the fourth and fifth planes on the other. The paperclip is hidden inside the folded binding device.

By this means the paper band is easily folded and unfolded. In the course of its clasping, clamping or disconnection, no damage, tearing, scratching or nicking of the bound papers occurs, nor deformation of the paperclip. This procedure allows for the manual or mechanical folding of the binding device, which means a cheap means of manufacture and easy launching thereof.

If the paper band is printed prior to its actual folding, advantageously on the surfaces of the planes situated on the outer surface of the binding device following its folding, a printed binding device is gained, which further expands its flexibility of use and application for the cheap and attractive depiction of indicia in various sizes, shapes and colors.

Brief Description of the Drawings The invention is described in detail in the following example of execution, which is illuminated in the attached schematic drawings, in which are represented fig. 1 composition of the paper band, fig. 2 the paper band with the positioned paperclip, fig. 3 the first folding of the band, fig. 4 the second folding of the band, fig. 5 moving the last plane towards the opposite end of the band, fig. 6 the binding device and fig. 7 the application of the binding device.

Description of Embodiment Examples In fig. 1 is depicted a cut section of semi-rigid, foldable paper, of thickness, weight and folding properties corresponding to that of a standard calling card. The paper has the form of a continuous, rectangular band of one specific length and one specific width, whereby these dimensions are dependent on the paperclip used. The paper band is divided along the length into five planes 1, 2, 3, 4, 5 separated in section by four parallel folds 6, 7, 8, 9 in the form of so-called bigs, formed for example by means of the impact of a blunt instrument on the surface of the paper.

The individual planes 1, 2,3, 4,5 are rectangular, their width 13 corresponding to the width of the paper band, their length corresponding to the distance between the folds 6 7, 8, 9.

In fig. 2 is depicted the beginning of folding of the paper band, on the first, partially <BR> <BR> folded, plane 1 of which is positioned a common wire paperclip 10, consisting of a<BR> longer loop 11 and a shorter loop 12. The length 14 of the first plane 1 corresponds<BR> approximately to the length of the shorter loop 12 of the paperclip 10, or is slightly<BR> shorter, in order that the first plane 1 can move and the shorter loop 12 can reach<BR> directly to or close to the first fold 6, which is important for the actual folding of the paper band. The length of loop 11 of the paperclip 10 extends across the first plane 1 and its length corresponds approximately to the length of the second plane 2.

In fig. 3 is indicated the completed first folding of the first plane 1, where the first<BR> plane 1 together with the paperclip 10 is folded down onto the second plane 2 along the<BR> first fold 6, whereby the longer loop 11 on the folded first plane 1 comes to the top and<BR> extends beyond this first plane 1. The shorter loop 12 is situated inside the band.<BR> <P>In fig. 4 is depicted the second folding of the paper band, whereby the second plane 2<BR> is folded across the second fold 7 to the third plane 3, the length of which should<BR> correspond approximately to the length of the longer loop 11 of the paperclip 10, or should be slightly greater, in order that the paper band may be further conveniently folded, and in order that the longer loop 11 of the paperclip 10 reaches directly or closely to the fold 8 between the third plane 3 and the fourth plane 4. Following this <BR> <BR> folding, the shorter loop 12 and also the longer loop 13 of the paperclip is situated<BR> within the planes 1, 2, 3 folded from the right end of the paper band. For reasons of easy folding, it is advantageous that the length of the first plane 1 be less than that of the second plane 2.

In fig. 5 is indicated the continuation of folding, executed from the opposite end of the paper band. The outer, fifth plane 5 is first folded across the fourth fold 9 to the fourth plane 4.

In fig. 6 is depicted the execution of the final folding task, in which the free end of the fifth plane 5 very easily slides above the longer loop 11 of the paperclip 10 and under the first plane 1. With the continuation of this sliding, the entire fifth plane 5 and part <BR> <BR> of the fourth plane 4 gradually move underneath the first plane 1. It is evident that the<BR> sum of the lengths of the fourth plane 4 and the fifth plane 5 will be approximately<BR> equal or corresponding to the length of the third plane 3, on which the fourth plane 4 and the fifth plane 5 lie upon completion of folding.

Following completion of folding, the final binding device 15 is created, the upper <BR> <BR> surface of which consists of the second plane 2 and partly from the fourth plane 4, the<BR> right edge of which consists of the second fold 7 and the left edge of the third fold 8,<BR> whereby the bottom surface of the binding device 15 consists of the third plane 3.<BR> <P>Inside the binding device is created the V-shaped groove 16. The paperclip 10 is situated inside the thus acquired binding device 15 and is not visible from any external side.

In fig. 7 is then depicted the use of this binding device 15 for the binding of the upper edges of loose sheets of paper 17. The binding device 15 binds these loose sheets 17 in such a manner that the upper edges of these sheets 17 slide into the V-shaped groove 16, i. e. between the internal positioned surfaces of the folded binding device 15, specifically between the first plane 1 the fifth plane 5 and partially the fourth plane 4.

The outer surfaces of the binding device 15, i. e. the second plane 2 and the third plane 3 may thus be used for advertising, promotion, classifieds etc.

The removal and re-using of the binding device 15 does not cause damage to the originally bound sheets of paper 17 nor to the paper band itself or the paperclip 10. The binding device 15 may be repeatedly used. <BR> <BR> <P>Manufacture of the paper band for the binding device 15 may effectively proceed thus,<BR> that a sheet of paper is first printed with the required design and the decoration of the surfaces of the second plane 2 and the third plane 3, which will be the outer surfaces of the binding device 15 following folding. Subsequently, the pressing of the folds 6, 7, 8 t the so-called bigs, for the creation of the planes 1, 2, 3, 4, 5 is executed, and the sheet is then cut into individual paper bands for individual binding devices 15.

The indicated example of execution does not exclude other possible means of execution and combination of the binding device 15 in the context of the extent of intellectual patent claims.

Industrial Applicability The binding device 15 represents a closing, clamping or clasping device for the simultaneous binding of loose papers, or as registers or glides separating individual sheets, e. g. in filing systems, or as labels, hanging shields, name plates, removable positional price tags, page fixing bookmarks, fixing display cards, etc. The pre-printing of the binding device is intended for advertising, classifieds etc.
