A CONNECTION TO ENGAGE A NOTEBOOK WITH RELATIVE METAL BINDER WITH A COVER

DESCRIPTION

It is conventional to provide a cover for notebooks, diaries or the like, with hooks applied in a relatively costly way in exact positions inside the spine of the cover; these hooks - facing one another - must engage the ends of the metal binder which is part of the notebook.

These solutions are rather costly, relative to the intrinsic value of the assembly, the production of which must be automated and mechanized as much as possible with minimum manual operations.

The invention has attained the object of being inexpensive to produce, and also aesthetically pleasing, not attained by current fastening systems of the hooks forming the constraining connections of the binder, said current systems being at times unsatisfactory from the aesthetic point of view. These and other objects and advantages will be apparent from the text hereunder.

The invention concerns a connection to engage a notebook with relative metal binder to a cover, said connection comprising a filiform element (mainly metal) which forms at the ends two hooks for engagement of said metal binder and which extends on the outside of the cover along the spine, while the hooks pass through holes punched in the spine to penetrate and engage the ends of said binder.

In a possible solution, the filiform element is also shaped in at least an intermediate position with a section defined by two bends; two further punched holes are formed in said spine at the level of the two bends, so that said section is positioned on the inside of the cover. Said internal section can extend parallel to the metal element. In the drawing:

Figure 1 shows an exploded perspective view; Figure 2 shows a section according to H-Il in Figure 1 ; and

Figure 3 shows a partial view of the spine of the cover. In the drawing the cover in indicated with 1, with two folding parts 1A and 1 B and a spine 1C, along the inside of which the metal binder 2 (ring, spiral or

the like) for the notebook to be held in the cover must be engaged.

For this purpose a filiform or thread-like element 3 (such as a metal thread-like element, e.g. a wirelike element) is provided, of a length less than the dimension of the spine 1C and which forms at the ends two hooks 3A facing each other and sufficiently distanced to engage - just as conventional connections - the ends of the binder 2, which can be slightly bent for this purpose.

The element 3 is engaged along the spine 1C of the cover 1, 1A, 1B, 1C by providing therein two holes 5, through which the two hooks 3A are made to pass, with two subsequent simple operations to pass first one and then the other hook through the respective hole 5. In this way the element 3 is positioned outside the spine 1C while the hooks 3A are inside in conditions to hook the ends of the metal binder 2.

For improved engagement of the element 3 to the spine 1C, and also for aesthetic requirements, the element 3 can be shaped with at least a pair of bends 3C which define therebetween a section 3E of the element 3; two further holes 9 are made in the spine 1C. In this way the element 3 can be inserted subsequently into the holes 9 so that the section 3E remains inside the spine and the two bends 3C are housed in said holes 9; the two sections 3F contiguous to the section 3E remain on the outside, to obtain greater adhesion of the element 3 to the spine 1C and improve the aesthetics.

In any case, the solution according to the invention offers the advantage of extremely simple application with an aesthetically pleasing effect. Production of the element 3 can be easily automated and application only entails making holes in the cover and a relatively simple manual operation to engage the element therein.
