Definitions

  • the present invention relates to a zip fastener with closure with couplable profiles.
  • the zip fastener according to the invention is produced using front-interlocking coupling profiles obtained mainly, though not exclusively, by extruding plastic and/or metal material or derivatives thereof.
  • Said profiles have a front-interlocking configuration which enables their reciprocal linear coupling for the purpose of joining, with reciprocal fastening, of two opposite strips of fabric or another material to be joined, being typically used as a closure system for items of clothing.
  • the present invention is advantageously applied in the field of metalworking and mechanical engineering, small parts manufacture, stamping and moulding, fashion, textiles and leather goods, footwear, clothing and furnishings, and in general in the field of systems for closure, sliding and fastening of elements made of various materials to be joined.
  • the zip fastener according to the invention may also be used in the fashion and textile industries and in all applications regarding fastenings or zippers.
  • zip fastener also called zipper
  • zipper normally composed of two series of teeth, each fixed to a corresponding tape or strip or another surface, which engage with each other during closing in order to join the two parts
  • a wedge element of a shape such as to enable the engagement or disengagement of the teeth during the sliding of the slider in one direction or the other.
  • the slider has the function of sliding between the two parallel rows of teeth in such a way as to engage them or disengage them to obtain the closing or opening of two strips of material.
  • a zip fastener can further be provided, at the opposite ends of the series of teeth, with stop elements, which prevent the slider from slipping off at the beginning and end of its travel.
  • the actuator tab is generally permanently attached to the slider, for example by closed ring portions, provided at one end of the tab and on the back of the slider.
  • zip fasteners may be grouped together: ones with polymeric plastic teeth that are moulded, ones with polymeric plastic teeth that are sewn with thread, and ones with metal teeth, which provide for the anchorage of each single metal or metal alloy tooth using a die-casting technique or blanking technique.
  • Every technique for producing a zip fastener is associated with a strip of fabric called "tape", wherein at the end thereof there is a thicker zone, usually cylindrical, along the longer side, which contains additional yarn.
  • the tape generally consists of a polyethylene PE yarn or cotton yarn or a mix of elastomer and cotton depending on the type of zip fastener, its use and the expected aesthetic and sensory result.
  • the prior art envisages that a previously heated nylon thread is sewn with a spiral trajectory into a fabric tape with a respective beaded edge. While the sewing machine winds the pre-heated thread, sewing it, in the point farthest from the fabric tape, the sewing carriage has an abrupt movement towards the part yet to be sewn, that is, upwards, and then returns into an elliptical trajectory.
  • the instantaneous deformation of the trajectory enables a projection to be created on the thread, the same projection that is present in the lower part of the "metal" tooth; this projection is the part that is inserted in the correspondingly created recess, thus enabling the union of two sequential elements, identified as the main point of closure.
  • the first effective zip fastener system based on the application of a plurality of teeth, in this case metal ones, which face one another in a staggered fashion on two opposite sides of a tape, wherein said teeth determine a line of closure, being provided with a recess at the top and a projection at the bottom.
  • the closing of said teeth is due to the sliding of a slider which is shaped so that, during passage, it will enable the divarication of the space between one tooth and another and the subsequent reciprocal interlocking interpenetration of the alternatively joined teeth.
  • This solution provides for the creation of a front sheath obtained by folding on itself the final part of the strip of fabric using thick fabrics or leather that replace the beaded edge, given the similarity in the folding on itself.
  • the coupling of the tooth itself on the tape is shifted, and the strip of fabric, rather than entering from the rear part of the tooth, is coupled onto the front part of the tooth and, as the excess strip of fabric is folded on itself, comes out of the upper part.
  • There are recesses on the excess part which comes out at the front to permit the tooth to be anchored with the respective front tooth, the front strip thus taking on the form of a sheath filling the free and open spaces, which limits and in some cases prevents the passage of liquids and air.
  • a tooth which, in a commercial context, will be called symmetrical is proposed. It is a tooth that is axial-symmetrical on both axes and no longer has a line of closure with an upper recess and lower projection; rather, the coupling projection is now present both at the top and bottom and the anchorage recess thereof is consequently present on both the upper and lower surfaces, with an increase in tensile strength and a nearing of the teeth no longer arranged in a "Z" configuration, but rather with an arrangement that increasingly resembles uniform rectangles, a continuous band of parallelepipeds.
  • a zipper comprises a magnet on the initial interlocking element, and in this case the stop where the first two strips of fabric are joined, or the point in which the sliding of the fabric begins (or ends in the case of separation), becomes an "automatic" connection, i.e. without the person having to insert the strip of fabric anchored to the pin inside the reader/slider, thus beginning the joining of the two strips of fabrics.
  • the problem has been partially solved by creating, using a rather laborious method, a housing that almost totally disengages the slider, thus closing the zip fastener without causing the slider to come off the two tracks.
  • the known zip fasteners can provide little resistance if subjected to stresses of varying nature and in different orientations simultaneously; - zero resistance in the event of breakage of a single tooth or lack of anchorage between a pair of teeth;
  • the present invention aims to provide a zip fastener with sliding zips which avails itself of a plurality of coupling teeth making it possible to exploit the bending of the material in favour of a type of closure with front abutting of the teeth, thus obtaining a product capable of eliminating or at least reducing the drawbacks highlighted above.
  • the invention aims in particular to provide a zip fastener with a closure with front abutting and fastening couplable profiles which enables the traditional method of a sliding closure to be modified.
  • the invention aims to modify the traditional closure by means of a layer-on-layer system with alternating insertion into a front closure, for opening by bending or by translation and rotation of the closing elements.
  • This conception makes it possible to obtain a sliding of the closure elements of the zip fastener with a variable angle or a fixed angle of entry so as to permit an interlocking of the two elements, and vice-versa, in an analogous manner, the same constraint releases the elements in order to pass from a closed condition to an open one.
  • the closure system according to the invention makes it possible to reduce, minimise and in some cases even eliminate the passage of fluids, water and air, both between one tooth and another, understood as a progressive sequence of attachment to the tape, and between the teeth to be coupled, set facing each other.
  • the zip fastener according to the invention offers the possibility of defining fixed maximum or minimum rotation angles between the rest surface of a tooth and the perpendicular axis of the subsequent tooth, and to increase the tensile strength and decrease the weight of the individual component tooth, thanks to the introduction of the possibility of using a double beaded edge.
  • the zip fastener according to the invention further enables the mechanics of the slider to be simplified by eliminating the need for parts that stop the sliding of the slider when the pull tab is not raised, so as to prevent the zip fastener from opening by itself.
  • the zip fastener makes it possible to decrease the manufacturing steps necessary in traditional processes using a technique of drawing deformation and subsequent blanking for the individual tooth, as it maintains only the blanking step, without drawing, with a clear advantage from a production standpoint.
  • the zip fastener according to the invention enables the closing - sliding - sensations of the slider to be changed by adding magnetic material inside the tooth and slider.
  • the magnets arranged with all poles identical between the tooth and slider repel each other, creating a better sensation of slidability.
  • the zip fastener according to the invention makes it possible to increase the possibility of customising the elements making up the zip fastener, both through an addition of further components, e.g. by embedding, and through the possibility of introducing processes, e.g. laser engraving or screen printing.
  • the zip fastener according to the invention further avoids the need to produce additional elements, besides the slider and tooth, necessary for the functioning of a zip fastener; for example, it enables stop elements or stopping points to be eliminated.
  • zip fastener consists in a reduction of the machinery necessary for the assembly and production of a zip fastener, as it decreases the number of steps necessary to form an individual tooth, thus decreasing the number of machines used and simplifying the remaining ones. In this manner, one indirectly increases the rate of production of the object, understood both as the process of moulding or stamping an individual tooth and the time of a complete cycle for the production of a zip fastener, including assembly.
  • the zip fastener according to the invention makes it possible to exploit a single element - a tooth of the zip fastener system - as a closure element usable individually independently of the zip fastener context; for example, a single tooth could be used with the function of a button for fabrics.
  • the zip fastener according to the invention makes it possible to carry out two-component or multi-material stamping or moulding for the formation of a tooth.
  • a new advantage offered by the zip fastener according to the invention lies in the possibility of choosing alternative polymeric or metal materials which were not used up to now because of their unsuitability for the type of features required.
  • a further object of the invention is the possibility of unifying the design of the zip fastener, specifically of unifying the design and the exterior appearance of the inside, using a single design both for metal/alloy models and moulded polymer products.
  • a further accessory that may be obtained is a slider which permits the 360° rotation of the pull tab.
  • the rotation of the pull tab is not given by a particular geometry of the pull tab, but rather by the possibility of having an intermediate plane inside the slider which enables the pull tab to rotate by any angle.
  • a further advantage obtainable by the invention is the impossibility of autonomously opening the zipper if the slider has no stop. If only one of the two strips of material (fabric) making up the zipper is pulled, the zipper will not open.
  • the zip fastener according to the invention makes it possible to eliminate the passage of light in the middle of the zipper, the point where the teeth of the right chain are joined with the left chain.
  • the zip fastener according to the invention avoids the need for a structural change, and thus for a new production process, as well as the respective machinery and costs for producing the new structure of the coupling tooth should it be necessary to introduce an accessory (sheath) designed to further decrease the passage of air/fluids.
