Definitions

• Temporal binding system and method, and ring-element implemented in this system DESCRIPTION
• the present invention relates to a temporary binding system. It also relates to the temporary binding process implemented in this system, as well as a ring-element at the base of this system.
• a widely used temporary binding system implements a central binding strip provided over its entire length with a set of claws shaped so as to be normally overlapped.
• the implementation of this temporary binding system requires the use of a specific device and it is relatively delicate and time consuming to modify the binding obtained. Furthermore, this binding system does not allow complete folding of the connected elements.
• This object is achieved with a system for temporarily connecting elements provided with perforations, comprising a set of element rings each having an opening over their entire width to allow their introduction into perforations of each of said elements to be connected.
• each element ring has a permanent opening corresponding to an absence of material on a determined angular portion of said element ring, and a profile adapted to provide several points of contact with the perforation in which said element ring is introduced.
• the two first and second flat elements are provided with perforations to receive the element rings and the back piece is fixed to said first and second flat elements, so that in the closed position the piece of back completely covers the element rings while in the folded position the back piece is completely inserted between the two dish elements.
• a method for temporarily connecting elements provided with perforations, implemented in the temporary binding system according to the invention characterized in that, in order to add an element to be connected or to remove a connected element, the respective openings of the element rings are aligned beforehand by rotation of these element rings, and to close (lock) the binding, the openings are misaligned.
• the temporary binding system offers the possibility of folding the elements indefinitely at the back of the book (hence a minimal bulk), and of linking thick and rigid elements. Furthermore, it allows a perforation spacing which is not necessarily regular, as well as a wide variety of authorized forms of perforation. Furthermore, with this temporary binding system, the edges of the connected elements can be aligned along a convex curve which facilitates their handling.
• the element-ring structure of the temporary binding system according to the invention also provides a high level of robustness and lightness and makes it possible to personalize the format of the elements to be linked.
• FIG. 1 is a view of a ring-element used in a temporary binding system according to the invention
• - Figure 2 illustrates a particular step in the temporary binding process according to the invention, during which the respective openings of the element rings are aligned
• 3 shows, along a section plane AA in Figure 1, different possible profiles of a ring-element according to the invention
• FIGS. 4A, 4B and 4C illustrate three situations characteristic of a first embodiment of a temporary binding system according to the invention
• FIGS. 5A, 5B, 5C and 5D illustrate four situations characteristic of a second embodiment of a temporary binding system according to the invention.
• a ring-element 10 has, with reference to Figure 1, an opening 1 over its entire width to allow its introduction into one of the perforations of each of the elements to be connected.
• the width of this opening represents only a small proportion of the circumference of the ring.
• the thickness of the ends 2, 3 progressively thinner from its inner circumference 4 to its outer circumference 5.
• the edges of the ends 2, 3 are rounded on both sides of the element ring.
• the material of realization of the ring-element must combine robustness and lightness. The surfaces must be smooth in order to limit friction against the interior edges of the perforations.
• a temporary binding system S comprises a set of element rings 10-1, ..., 10-N, as illustrated in FIG. 2. These element rings can be introduced through their respective openings in perforations Pl, ..., PN of an element to be linked, for example a document in the form of a sheet of paper.
• the assembly of the elements to be connected within the temporary binding system S can be carried out as follows: a) introduction of all the necessary element rings in the perforations of the most rigid of the elements to be connected, if this choice exists; b) maintenance of the first plated element on any support (table ...) and alignment of opening all the element rings to add, one after the other, all the elements to be connected; c) end of the assembly: the misalignment of the opening of the rings locks the binding.
• the elements can then rotate freely around the binding rings and be folded down indefinitely on the back of the book.
• the aligned openings form a slide.
• the element to be connected is presented by one of its ends to one of the ends of this slide. It is introduced into it and slid in until its positioning in the binding is adequate and its perforations are at the level of the corresponding rings. The element is then gently hoisted partially out of the slide in a movement which places the perforations opposite the ends of the rings, to then effect the introduction of these ends into the perforations of the element. The element is then gently shaken to complete its installation.
• the system according to the invention does not involve severe constraints of format or number of the elements to be connected. It should however be noted that at least two element rings are necessary for the system to function and that too many rings can cause significant friction. Furthermore, the system according to the invention does not impose any particular constraint on the spacing of the perforations between them. According to particular embodiments, the temporary binding system according to the invention can be available in different diameters (for example 1 cm, 1.5 cm, 2 cm, etc.) allowing the production of assemblies of various thicknesses depending on the number and thickness of the elements to be connected. The profile of the ring can have different shapes in order to best adapt to the perforations for which the ring is intended, as illustrated in Figure 3.
• the profile of the ring-element must indeed be adapted to the type of perforation used, to achieve sufficient contact between the element ring and the internal edge of the perforation, with several points of contact between the element ring and the perforation.
• a back D made of a flexible material, for example based on canvas or a sheet of plastic material according to conventional binding techniques, is fixed both to the front PR1 'of the first flat PLI' and to the - S -
• the two plates PLI ′, PL2 can be articulated around the rings-elements 10-1, -,., 10-N whose misalignment ensures the locking of the binding.
• the first flat PLI ' can be completely folded under / against the second flat PL2 ( Figure 4C).
• the back D is then inserted between the front of the first flat PLI 'and the back of the second flat PL2.
• the back D is fixed on the one hand to an edge Bl of the front of the first flat PLI '' no perforated and on the other hand on the back PV2 of the second flat PL2 which is provided with perforations arranged to receive the element rings 10-1, ..., 10-N.
• the back D is fixed on the back of the second plate PL2 is carried out behind the edge of this second plate beyond the perforations.
• first folding position illustrated in FIG. 5C the first flat PLI '' and the second flat PL2 are substantially opposite and the back D is folded against the element rings 10-1, ..., 10 -NOT .
• the connected structure occupies a minimum overall width.
• a second folding position illustrated in FIG. 5D the back D is stretched and the first flat PLI 1 'is offset relative to the second flat PL2. This position allows easy access to all of the element rings, in particular for aligning or misaligning them in order to add or remove an element.
• FIGS. 4A to 4C and 5A to 5D do not represent elements inside the bindings. It goes without saying that the temporary binding system according to the invention is all the more effective and easy to handle when a sufficient number of elements are connected by this system in particular in order to ensure correct maintenance of the element rings. . This depends in particular on the nature and the dimensional characteristics of the elements to be connected, as well as on the number of element rings constituting the binding.
• the invention is not limited to the examples which have just been described and numerous modifications can be made to these examples without departing from the scope of the invention.
• the temporary binding system according to the invention can be implemented in fields other than that of binding of publishing documents, for example in urban furniture, signage, information panels or commercial presentation materials, especially for tiling.
