Method of securing the hinge element of an eyeglass hinge to a frame component

Abstract

The invention relates to a method for fixing a hinging element of an eyeglasses hinge to a component of a frame made of a polymeric material. The hinging element comprises an anchoring portion with a stem and an enlarged head with a housing seat in which a TAG electronic component is housed at an insertion distance from the outer end of the anchoring portion. The method comprises a phase of realising a pre-seat in the component, a phase of heating the anchoring portion of the hinging element, and an immersion phase in which the heated anchoring portion is inserted in the pre-seat, causing the softening of the polymeric material adjacent to the pre-seat, so that part of the polymeric material enters the undercut region of the anchoring portion. The depth of the pre-seat of the frame component is greater than or substantially equal to the insertion distance of the TAG electronic component, so that, after the immersion phase, the electronic component does not press against the bottom wall of the pre-seat, preventing the softening of the polymeric material from exerting stresses on the TAG electronic component, thus avoiding its damage.

Description

TECHNICAL FIELD

[0001] The present invention relates to a method for fixing the hinging elements of an eyeglasses hinge to the components of the frame according to the preamble of the main independent claim.

[0002] The method in question has advantages in the production of frames of various types, both sporty and elegant, made both of metal and of plastic material, such as acetate.

[0003] The method in question therefore relates to the eyewear sector or to the field of eyewear production, more specifically to the field of production of eyewear components. BACKGROUND

[0004] As is known, the frame has a pair of hinges for connecting the two temples to the front portion of the frame.

[0005] More in detail, each hinge is made up of two hinging elements hinged together, wherein the first hinging element is fixed to the temple of the eyeglasses and the second hinging element is fixed to the front portion of the frame, or more precisely to the portion known in the sector as "nose".

[0006] Functionally, the hinges in question allow the temples to rotate between a closed position, in which they are folded to the front portion, and an open position, in which they are substantially at right angles to the front portion.

[0007] Eyeglasses in which the frame, i.e. the front portion and the temples, are made of a polymeric material, such as acetate, are particularly popular on the market. In eyeglasses of this type, the hinging elements, usually made of metal, are fixed to the components of the frame by at least partially immersing the hinging elements in the polymeric material that constitutes the temples or the front portion.

[0008] For example, the first hinging element of the hinge is fixed to a metal core, for example by welding, which is immersed in the polymeric material that constitutes the temple.

[0009] The second hinging element is provided with an anchoring portion, known in the sector as small anchor or small mushroom, having a plurality of appendage protrusions on it for immersion in the plastic matrix of the front portion. More in detail, this hinging element comprises an enlarged base provided with two opposite faces, at least one hole for the engagement of the hinge pin being developed from one of the faces, the anchoring portion being protruding from the other face. The anchoring portion is provided with a shank which develops perpendicularly to the enlarged base, from a base end fixed to the enlarged base to a free end having the plurality of appendage protrusions, which together with the base define an undercut.

[0010] The anchoring portion of the hinged element is fixed to the front by means of an immersion process which heats (for example by induction) the anchoring portion to a temperature higher than the melting temperature of the acetate, thus inserting it into the acetate material. This insertion operation is usually performed in an automatic or semi-automatic manner by means of actuators which exert on the hinged element, and therefore on the front, a force which is rather high and able to penetrate the anchoring portion. During this operation, the hot anchoring portion melts the area of the front with which it comes into contact, thus penetrating into the front, in such a way that the melted polymeric material penetrates into the undercut defined by the appendage of the anchoring portion and, by solidification, retains the anchoring portion, and therefore the hinged element, in the front. In particular, before inserting the anchoring portion into the polymeric material of the front, a pre-seat is provided on the front which facilitates the necessary penetration of the anchoring portion into the polymeric material. The depth of this pre-seat must be significantly less than the length of the anchoring portion, in order to allow the anchoring portion to move part of the polymeric material (by melting) when it is inserted into the pre-seat, so that it penetrates into the undercut between the appendage and the base.

[0011] There is a particular need in the eyewear sector to associate the frame with an identification device capable of transmitting specific information (for example, in particular, information relating to the authenticity of the frame) by means of a reading device. More precisely, in the eyewear sector, there is a particular need to make eyewear equipped with an identification device in order to be able to distinguish the authenticity.

[0012] For example, according to Korean patent KR100893185, an eyewear is known with a frame having a base closed with a lid, inside which an identification device is housed, for example of the RFID type, capable of being read by an external reading device. Japanese patent JP2007011013, Japanese patent JP2006227936, US patent US2013 / 0169924 and US patent US2009 / 0303429 also disclose similar eyewear solutions with frames provided with an identification device.

[0013] All these eyewear solutions have the drawback of affecting the aesthetics of the frame by providing a special base for the identification device in a very visible place.

[0014] To eliminate this drawback, a solution has been developed in which the identification device is inserted in a hinged element of the hinge, described in Italian patent application IT20201700014126. In particular, this known solution uses a TAG assembly comprising a support body in plastic material (for example, polycarbonate) which houses a pre-seat for containing the electronic identification device, in order to protect it during the production of the frame.

[0015] In particular, the TAG assembly is housed in a housing seat located in the anchoring portion of the hinge articulation element (for fixing to the front of the eyeglasses). The housing seat is formed axially on a stem of the anchoring portion and is provided with an access between respective appendage protrusions at the free end of the stem. The articulation element with the TAG assembly is fixed to the front by means of the above-mentioned immersion procedure.

[0016] In particular, during this immersion process, when the heated anchoring portion is inserted into the preformed seat by melting the adjacent polymer material region, as the anchoring portion penetrates, the polymer material enters the housing seat by exerting a strong pressure on the TAG assembly. The combined effect of the high temperature (due to the heating of the anchoring portion) and the pressure exerted by the molten plastic material causes the polycarbonate support of the TAG assembly to soften and deform, thus causing the electronic devices inside it to be subjected to a thrust that can damage them, in particular by pressing them against the inner wall of the anchoring portion housing seat.

[0017] Therefore, there is a need to optimize the production phase of the frame in order to prevent damage to the electronic identification devices during the fixing of the articulation element of the hinge to the plastic components of the frame. SUMMARY

[0018] In this context, the fundamental problem of the present application is to eliminate the drawbacks of the prior art described above by providing a method for fixing the articulation element of the hinge of the eyeglasses to a component of the frame, which is able to fix the articulation element to the component of the frame without damaging the TAG electronic components placed in the articulation element.

[0019] Another object of the present application is to provide a method for fixing the articulation element of the hinge of the eyeglasses to a component of the frame, which is both simple and inexpensive to implement.

[0020] Another object of the present application is to provide a method for fixing the articulation element of the hinge of the eyeglasses to a component of the frame, which is completely reliable in operation. BRIEF DESCRIPTION OF DRAWINGS

[0087] According to a third embodiment of the hinging element 3, for example as shown in Figure 15a and 15b , the housing seat 18 is devoid of the above-mentioned side slits.

[0088] In particular, according to Figure 8a - a variant of the second embodiment of -b, the housing seat 18 is devoid of the through slit 23 at the second end 10 of the anchoring portion 6.

[0089] Advantageously, the TAG electronic component 19 is designed to store information and transmit it to a reading device ("reader") in a conventional manner. Typically, these information concern the characteristics of the hinge and / or of the eyewear associated with the TAG electronic component 19, and in particular can contain an identification code for authenticating the eyewear, for example relating to its source of production.

In particular, with reference to the embodiments shown in Figures 5-7b and 15a-b, the second side 19B of the TAG electronic component 19 faces the inlet opening 20 of the housing seat 18, while in the embodiments shown with reference to the figures in Figure 8a - b, the second side 19B faces the through slit 23.

[0091] Advantageously, the TAG electronic component 19 develops according to a development axis H of its own, between a first end 19' and an opposite second end 19".

[0093] Advantageously, with reference for example to Figures 5-9bThe TAG electronic component 19 includes at least one electronic identification device 25, and more preferably also includes at least one support layer (e.g., made of an electronic card), an antenna, and a chip (mounted on the support layer and connected to the antenna).

[0094] Conveniently, the electronic identification device 25 is of a passive type, such as RFID or NFC, i.e., a unified transmission standard; obviously, the electronic identification device 25 may also be of a standard other than RFID or NFC or an active type, without falling outside the scope of protection of this patent.

[0095] Advantageously, the TAG electronic component 19 also includes a support 26 having a base 27 for receiving the TAG electronic identification device 25. Conveniently, the support 26 has an outer surface 28 extending about the development axis H and forming an access opening 29 thereon to introduce the electronic identification device 25 into the base 27.

[0096] Ideally, the support 26 is made of a polymer material, such as polycarbonate.

[0097] Advantageously, the support 26 extends along the development axis H between a first head and a second head, which respectively define the first end portion 19' and the second end portion 19 of the TAG electronic component 19.

[0098] According to the embodiment shown in the accompanying drawings, the first head of the support 26 has a substantially tapered shape and the second end of the support is substantially flat (and perpendicular to the development axis H). Clearly, the head of the support 26 (and therefore the end portions 19', 19" of the TAG electronic component 19) may also have a different shape and / or angle than the example shown.

[0099] Advantageously, refer to Figures 5-7b In embodiments 15a-b, the TAG electronic component is positioned within the receiving seat 18 of the anchoring portion 6, and the development axis H is substantially parallel to the first development direction Y1 of the anchoring portion 6.

[0100] Specifically, in this embodiment, the first end portion 19” of the TAG electronic component 19 defines the aforementioned first side 19A of the electronic component and faces the connecting portion 5, while the second end portion 19” of the TAG electronic component 19 defines the aforementioned second side 19B, and in particular, when the hinge element 3 is applied to the component 2, it faces the inside of the component (and more particularly faces the bottom wall 42 of the preset seat 40 on the component 2, as described in detail below).

[0101] Advantageously, the second end portion 19" of the TAG electronic component 19 is arranged at the second end 10 of the anchoring portion 6. In particular, the second end portion 19' of the TAG electronic component 19 can be arranged in a recess with respect to the second end 10 (as shown in the example of the figures), or substantially flush, or even (slightly) protruding.

[0102] Conveniently, the second end portion 19' of the TAG electronic component 19 faces the access opening 20 of the housing seat 18 and is intercepted by the first development direction Y1 of the anchoring portion 6 of the hinged element 3.

[0103] According to Figure 8a - the second embodiment, indicated with -b, the TAG electronic component 19 is arranged inside the housing seat 18 of the anchoring portion 6 and develops with an axis of development H substantially perpendicular to the first development direction Y1 of the anchoring portion 6.

[0104] In this second embodiment, in particular, the first side 19A of the TAG electronic component 19 is determined by a first region of the outer lateral surface 28 of the support body 27, which faces the coupling portion 5 of the hinged element 3, while the second side 19B of the TAG electronic component 19 is determined by a second region of the outer lateral surface 28 of the support body 27, which is diametrically opposite to the first region with respect to the axis of development H and is oriented on the second end 10 of the anchoring portion 6.

[0105] The second side 19B of the TAG electronic component 19 is located at a determined insertion distance D1 from the first end 9 of the anchoring portion 6. In particular, the insertion distance D1 is measured along a direction parallel to the first development direction Y1 of the anchoring portion 6.

[0106] If the second side 19B of the TAG electronic component 19 does not have a flat shape and / or is not perpendicular to the first development direction Y1, the insertion distance D1 is given by the maximum distance between the first end 9 of the anchoring portion 6 of the hinged element 3 and the second side 19B of the TAG electronic component 19.

[0107] Conveniently, in the case of the embodiments indicated with Figures 5-7b and 15a-b, the insertion distance D1 is given by the maximum distance between the first end 9 of the anchoring portion 6 of the hinged element 3 and the second end portion 19" of the TAG electronic component 19, in particular the second head of the support body 26.

[0108] In the case of the embodiments indicated with Figure 8a -b, the insertion distance D1 is given by the maximum distance between the first end 9 of the anchoring portion 6 of the hinged element 3 and the second region of the outer lateral surface 27 of the support body 26.

[0109] The operating phases of the method involved will be described below, in order to fix the hinged element 3 to the component 2 of the above-mentioned frame 1, mainly in terms of their structural features.

[0110] According to the present application, the method involved provides a phase of realization of a preformed seat 40 in the component 2 of the frame 1. Optimally, this realization phase is carried out by moving a cutting blade, for example by means of a tool operated by an operator or by means of a computer numerical control.

[0111] With reference to Figures 1-4 , the preformed seat 40 develops inside the polymeric material of the component 2 from an outer opening 41, which is formed on the coupling surface 4 of the component 2, to a bottom wall 42 along a second development direction Y2.

[0112] The distance between the outer opening 41 and the bottom wall 42 of the preformed seat 40 defines a first depth PI of the preformed seat 40.

[0113] Furthermore, the preformed seat 40 is provided with a first lateral wall 43, which extends around the second development direction Y2 and defines the preformed seat 40 transversely to the second development direction Y2, i.e. in width. This second lateral wall 43, transversely to the second development direction Y2, defines a first amplitude Al of the preformed seat 40.

[0114] Advantageously, with reference to Figure 9a and 9b , the method involved comprises a phase of insertion of the TAG electronic component 19 into the containment seat 18 of the anchoring portion 6 through the access opening 20 of the anchoring portion 6.

[0115] Optimally, after this insertion phase, the TAG electronic component 19 is retained in the containment seat 18 by the friction between the lateral wall 22 of the containment seat 18 and the outer lateral surface 28 of the support body 26 of the TAG electronic component 19.

[0116] With reference to the embodiment of Figure 9a , the TAG electronic component 19 is inserted into the containment seat 18 by moving it along the first development direction Yl of the anchoring portion 6, in particular with its development axis H parallel to this first development direction Yl, optimally until it touches the inner wall 21 of the containment seat 18.

[0117] With reference to the embodiment of Figure 9b , the TAG electronic component 19 is inserted into the containment seat 18 by moving it perpendicularly to the first development direction Yl of the anchoring portion 6, optimally until it is positioned between the two access openings 20 of the containment seat 18.

[0118] Said method, optimally after the above insertion phase, comprises a heating phase in which at least the anchoring portion 6 of the hinged element 3 is heated to a temperature higher than or substantially equal to the temperature of the polymer material of the component 2 in the softened (or melted) state. In particular, the anchoring portion 6 is heated with the TAG element 19 already inserted in the housing seat 18 thereof.

[0119] Advantageously, the heating phase can be implemented in a conventional manner by induction. For example, the anchoring portion 6 of the hinged element 3 is heated by means of an operating instrument having a metallic gripping head (for example in the form of a pincer) for gripping the hinged element 3, while heating by induction, also causing the hinged element 3 to be heated.

[0120] The temperature of the anchoring portion 6 of the hinged element 3 is for example comprised between 200°C and 400°C, depending on the specific application case.

[0121] After the heating phase, there is a phase of immersion of the anchoring portion 6 of the hinged element 3 in the polymer material of the component 2. With reference to Figure 10a - during this immersion phase, the heated anchoring portion 6 is inserted in the pre-arranged seat 40 until the first end 9 of the anchoring portion 6 is substantially flush with the coupling surface 4 of the component 2. Moreover, the heated anchoring portion 6 causes at least a portion of the polymer material adjacent to the pre-arranged seat 40 to soften (or melt), so that at least a portion of the melted polymer material enters the undercut region 13 of the anchoring portion 6.

[0122] For example, this operation comprises placing the component 2 in an operating station below an operating instrument for holding and simultaneously heating the hinged element 3, and controlling the descent of the gripping head of the operating instrument (for example by activating a suitable actuator), applying a suitable pushing pressure, until the anchoring portion 6 is made to enter the pre-arranged seat 40 of the component 2.

[0123] In particular, during the immersion phase, the hinged element 3 is arranged so that its first development direction Y1 is substantially aligned with the second development direction Y2 of the pre-arranged seat 40 and is moved in a motion parallel to the pre-arranged seat until the anchoring portion 6 is made to enter the pre-arranged seat 4.

[0124] Conveniently, the heating temperature of the anchoring portion 6 can also be regulated during the immersion phase, in order to optimize the process of insertion of the anchoring portion 6 in the component 2.

[0125] According to the concept of the present application, the first depth PI of the pre-arranged seat 40 is greater than or substantially equal to the insertion distance DI of the second side 19B of the TAG electronic component 19 with respect to the first end 9 of the anchoring portion 6 of the hinged element 3.

[0126] In this form, during the immersion phase, when the first end 9 of the anchoring portion 6 is flush with the coupling surface 4 of the component 2, the second side 19B of the TAG electronic component 19 does not press against the bottom wall 42 of the pre- seating 40. Basically, in this case, the second side 19B of the TAG electronic component 19 is at a distance from the outer opening 41 of the pre-seating 40 which is less than or substantially equal to the distance from the bottom wall 42 of the pre-seating 40, so that the pre-seating, and in particular the softened (or melted) polymeric material adjacent thereto, does not exert a counter-pressure on the TAG electronic component 19 (combined with the heating temperature) which could cause damage.

[0127] Advantageously, the first depth PI of the pre-seating 40 is greater than or substantially equal to the first length LI of the anchoring portion 6 of the articulation element 3.

[0128] In this form, during the immersion phase, when the first end 9 of the anchoring portion 6 is flush with the coupling surface 4 of the component 2, the second end 10 of the anchoring portion 6 does not press against the bottom wall 42 of the pre-seating 40. In this case, the second end 10 of the anchoring portion 6 is at a distance from the outer opening 41 of the pre-seating 40 which is less than or substantially equal to the distance from the bottom wall 42 of the pre-seating 40, so that this second end 10 does not exert a force on the bottom wall 42 which deforms it, so that the partially softened (or melted) polymeric material can enter the containment seat 18 (through the inlet opening 20 or the through slit 23 located at the second end 10 of the anchoring portion 6) and, under pressure, come into contact with the TAG electronic component 19, further guaranteeing its integrity during the immersion phase.

[0129] Advantageously, after the immersion phase, the bottom wall 42 of the pre-seating 40 is arranged substantially flush or spaced apart from the openings 20, 23 of the anchoring portion containment seat 18 located at the second end 10 of the anchoring portion 6, in particular Figures 5-7b the example inlet opening 20, or Figure 8a the example through slit 23, in such a way that the softened plastic material does not substantially enter the containment seat 18 and therefore does not affect the TAG electronic component 19.

[0130] Therefore, after the anchoring portion 6 has been inserted into the polymeric material of the component 2, the TAG electronic component 19, and optimally also the second end 10 of the anchoring portion 6, is not subjected to the pressure of the polymeric material of the component 2 which could damage it. In particular, the support body 26 of the electronic component, even if partially softened due to the heating phase, does not deform or subject the electronic identification device 25 inside it to stresses which could damage it, since it is substantially not subjected to the pressure of the polymeric material of the component 2.

[0131] Furthermore, according to the present application, the first amplitude Al of the pre-seating 40 is less than the first width Wl of the enlarged head 12 of the anchoring portion 6.

[0132] In this way, asFigure 10b - as illustrated by the example, during the immersion phase, the enlarged head 12 intercepts the first lateral wall 43 of the preformed seat 40, softens (or melts) the polymeric material adjacent to the first lateral wall 43 and penetrates into the first lateral wall 43, so that at least part of the polymeric material thus softened (or melted) enters the undercut region 13 of the anchoring portion 6. Thus, during the immersion phase, the enlarged head 12 of the anchoring portion 6 softens (or melts) the polymeric material of the first lateral wall 43 of the preformed seat 40 it affects, causing the softened polymeric material to collapse towards the inside of the preformed seat 40 after the passage of the enlarged head 12 along the first lateral wall 43, thus entering the undercut region 13 of the anchoring portion 6.

[0133] After cooling of the polymeric material, the anchoring portion solidifies, so that the anchoring portion 6 of the hinged element 3 is rigidly held on the component 2 of the frame 1.

[0134] Thus, according to what has been discussed above, according to the method involved, the dimensional relationship between the anchoring portion 6 of the hinged element 3 and the preformed seat 40 and the pre-configuration of the TAG electronic component 19, it is possible to avoid damaging the TAG electronic component 19 during the immersion of the anchoring portion 6, while ensuring that the anchoring portion firmly grips the component 2 of the frame 1.

[0135] Advantageously, during the immersion phase, the first protruding portion 15 of the enlarged head 12 of the anchoring portion 6 intercepts the first lateral wall 43 of the preformed seat 40 on opposite sides with respect to the second development direction Y2, so that the softened polymeric material can enter both undercut regions 13 of the anchoring portion 6.

[0136] Advantageously, the first width W1 of the enlarged head 12 of the anchoring portion 6 is greater than the first amplitude Al of the preformed seat 40 by approximately 0.5 to 3 tenths of a millimeter, or even 1 to 2 tenths of a millimeter.

[0137] Advantageously, according to the embodiment illustrated in the attached figures, after the immersion phase, the first face 31 of the enlarged base 30 of the anchoring portion 6 is positioned substantially flush with the coupling surface 4 of the component 2. With reference to these particular examples of the attached figures, this first end 9 of the anchoring portion 6 is determined by the first face 31 of the enlarged base 30.

[0138] In general, the first end 9 of the anchoring portion 6 is to be understood as the portion of the anchoring portion which, after the immersion phase, is positioned substantially flush with the coupling surface 4 of the component 2. "Substantially flush" can involve a tolerance range, the first end being protruding or recessed with respect to the coupling surface 4, for example by 1 to 5 tenths of a millimeter.

[0139] Advantageously, for example with reference to Figure 3 and Figure 4The pre-arrangement seat 40 of the component 2 is provided with an outer cavity 44 for housing the enlarged base 30 of the anchoring portion 6 of the articulated element 3, and with an inner cavity 45 for housing the enlarged head 12 and the stem 11 of the anchoring portion 6.

[0140] As discussed in detail below, the inner cavity 45 extends in width over the above-mentioned first amplitude Al (defined by the first lateral wall 43), and advantageously the outer cavity 44 extends in width over a second amplitude A2 greater than the first amplitude, and optimally substantially equal to the second width W2 of the enlarged base 30 of the anchoring portion 6.

[0141] With reference to the example of Figure 4 , the outer cavity 44 of the pre-arrangement seat 40 extends into the polymeric material of the component 2 along the second development direction Y2 between the outer opening 41 of the pre-arrangement seat 40 and a connecting base 46 (suitably located on an intermediate section between the outer opening 41 and the rear wall 42).

[0142] As shown in the example of Figure 2a and 2b , the above-mentioned connecting base 46 is provided with a base opening 47, which faces the bottom wall 42, and which communicates the inner cavity 45 with the outer cavity 44.

[0143] Advantageously, the outer cavity 44 is provided with a second lateral wall 48, which extends around the second development direction Y2 and defines the outer cavity 44 transversely to the second development direction Y2 (i.e. in width). This second lateral wall 48 defines the second amplitude A2 of the outer cavity 44 transversely to the second development direction Y2.

[0144] The inner cavity 45 of the pre-arrangement seat 40 extends between the bottom wall 42 and the base opening 47, and is defined by the first lateral wall 43 of the pre-arrangement seat 40 transversely to the second development direction Y2, which develops along the second development direction Y2 from the bottom wall 42 to the connecting base 46. The inner cavity 45 thus extends in width over the above-mentioned first amplitude Al of the pre-arrangement seat 40.

[0145] As can be seen in the example of Figure 4 , the distance between the base opening 47 and the bottom wall 42 defines a second depth P2 of the inner cavity 45;

[0146] Furthermore, the distance between the connecting base 46 and the outer opening 41 defines a third depth P3 of the outer cavity 44.

[0147] The sum of the above-mentioned second depth P2 and third depth P3 is equal to the first depth PI of the pre-arrangement seat 40; optimally, the third depth P3 of the outer cavity 44 is substantially equal to the third length L3 of the enlarged base 30 of the anchoring portion 6, in such a way that, after the immersion phase, the second face 32 of the enlarged base 30 substantially touches the connecting wall 46.

[0148] Advantageously, the second depth P2 of the inner cavity 45 is greater than or substantially equal to the above-mentioned second length L2 of the anchoring portion 6, so that, during the immersion phase, when the first end 9 of the anchoring portion 6 is flush with the coupling surface 4 of the component 2 (and the second face 32 of the enlarged base 30 touches the connecting wall 46) the second end 10 of the anchoring portion 6 does not press against the bottom wall 42 of the prepositioning seat 40 (as described above).

[0149] Advantageously, the bottom wall 42 of the prepositioning seat 40 is provided with a first perimetric edge 50 from which the first side wall 43 develops up to a first upper edge 51, defining the above-mentioned seat opening 47 of the connecting base 46.

[0150] Optimally, the connecting base 46 is provided with a second perimetric edge 52 from which the second side wall 48 develops up to a second upper edge 53, defining the outer opening 41 of the prepositioning seat 40.

[0151] According to Figure 3 and Figure 4 the embodiments illustrated, the first side wall 43 (and advantageously also the second side wall 48) has a substantially polygonal (for example substantially rectangular) cross section (transversal to the second development direction Y2). In particular, in the present embodiments, the first side wall 43 has two opposite first sides (the distance of which defines the first amplitude Al) which intercept the first protruding portion 15 of the enlarged head 12 during the immersion phase and are connected to two second sides.

[0152] Obviously, the first side wall 43 (and optimally also the second side wall 48) can also have a shape different from the polygonal, for example circular or elliptical, as illustrated in Figure 12a - the embodiments illustrated in -b and 13a-b (in which case, in particular, the first amplitude Al is defined by the radius or smaller radius of the cross section of the first side wall 43, respectively).

[0153] Advantageously, in addition to the above-mentioned inner cavity 45 and outer cavity 44, further cavities or compartments can be defined in the prepositioning seat 40.

[0154] According to another embodiment variant, not illustrated, the prepositioning seat 40 can also comprise a single cavity, in which the first side wall 43 develops up to the outer opening 41.

[0155] In particular, the bottom wall 42 defining the first depth PI of the prepositioning seat 40 should be understood as the wall from which the first side wall 43 develops, which defines the first amplitude Al of the prepositioning seat 40 and intercepts the enlarged head 12 of the anchoring portion 6 during the immersion phase.

[0156] According to the embodiment shown in the drawings, the first side wall 43 (and advantageously also the second side wall 48) is substantially parallel to the second development direction Y2, in such a way that, in particular during the immersion phase, the front face 17 of the enlargement head 12 intersects the first upper edge 51 of the first side wall 43 at the beginning. Obviously, the first side wall 43 (and advantageously also the second side wall 48) can also have different shapes and inclinations; for example, the first side wall 43 can have a conical shape towards the bottom wall 42, in such a way that, in particular during the immersion phase, the enlargement head 12 can intercept the first side wall 43 in an intermediate region between the first upper edge 51 and the bottom wall 42.

[0157] According to the embodiment shown in the drawings, the first side wall 43 (and advantageously also the second side wall 48) is substantially parallel to the second development direction Y2, in such a way that, in particular during the immersion phase, the front face 17 of the enlargement head 12 intersects the first upper edge 51 of the first side wall 43 at the beginning. Obviously, the first side wall 43 (and advantageously also the second side wall 48) can also have different shapes and inclinations; for example, the first side wall 43 can have a conical shape towards the bottom wall 42, in such a way that, in particular during the immersion phase, the enlargement head 12 can intercept the first side wall 43 in an intermediate region between the first upper edge 51 and the bottom wall 42. Figures 1-4 and 12a-b and 13a-b, the bottom wall 42 of the preseat 40 has a substantially flat shape and is suitably perpendicular to the second development direction Y2. Obviously, the bottom wall can also have different shapes and inclinations, depending for example on the shape of the second end 10 and of the enlargement head 12 of the anchoring portion 6. For example, as in the variant embodiment shown in Figure 14a -b, the bottom wall 42 is provided with a recess 60 suitable for receiving, for example, a portion of the second end 10 of the anchoring portion 6 which extends beyond the enlargement head 12.

[0158] In particular, in the case where the bottom wall 42 is not flat (or not completely flat), the first depth PI of the preseat 40 is given by the minimum distance between the bottom wall 42 and the outer opening 41 of the preseat.

[0159] Conveniently, in a conventional manner, the preseat 40, and in particular its cavities 44 and 45, also has an extension in depth (i.e. along a direction perpendicular to the first amplitude direction Al and to the second development direction Y2) which shape is not described in detail.

[0160] Advantageously, the dimensions of the preseat 40 are in line with the typical applications in the eyewear sector, for example of the order of 2-5 millimetres.

[0161] Advantageously, according to specific embodiments such as for example Figure 10c and 11 According to specific embodiments such as for example shown in

[0162] Advantageously, the first depth P1 of the pre-seating 40 is greater than the first length L1 of the anchoring portion 6 (and, optimally, the third depth P3 of the inner cavity 45 is greater than the second length L2 of the engagement segment 35 of the anchoring portion 6). In this form, at the immersion stage, when the first end 9 of the anchoring portion 6 is flush with the coupling surface 4 of the component 2, the second end 10 of the anchoring portion 6 is spaced from the bottom wall 42 of the pre-seating 40. In this way, the polymeric material of the component 2 does not enter the containment seat 18 in any form, and therefore it does not squeeze the TAG electronic component 19 substantially at all, further ensuring that the electronic component is not damaged during the immersion stage.

[0163] According to different embodiments, the first depth P1 of the pre-seating 40 is substantially equal to the first length L1 of the anchoring portion 6, which is just equal to the first depth P1 (unless there are tolerances in the production process) or greater than the first depth P1 by about one tenth to two tenths of a millimeter. Optimally, the second depth P2 of the inner cavity 45 is equal to the second length L2 of the anchoring portion 6, which has the same meaning as discussed above. In these latter embodiments, even if the polymeric material can come into contact or action on the TAG electronic element 19, the pressure exerted on the electronic element can be negligible, or in any case so low as not to cause damage to the TAG electronic element 19 itself.

[0164] Therefore, the fixing method thus conceived achieves the intended purposes.
