Description

MANUFACTURING METHOD FOR GLASSES AND GLASSES OBTAINED WITH SUCH METHOD DESCRIPTION OF THE INVENTION The invention relates to a manufacturing method for glasses that is capable of producing the component parts of a frame for glasses of a particular construction, the application of the support bars by means of a system for snapping and the assembly of the lenses in the frame while using the nose piece as a closing key for the assembly of frames and lenses, without using welding points and possibly screws as well. The manufacture of glasses is a process that is currently carried out to preliminarily prepare the relative frame, usually made from any suitable plastic material such as injection molding or cutting from a chaper, or metal from any sheet material. or wire, and subsequently subsequently assemble such a frame with the lenses as well as the support bars and the nose piece. Such a type of manufacturing process involves a number of intensive tasks, that is, phases of manual work both for preparing the frame mentioned above, and for adapting and mounting the support bars, the nasal piece and the lenses in the same frame. as well as the need to have their own arrangement: 1) expensive tools and machinery; 2) Exerted and trained work force to carry out each kind of particular work in the process; 3) prolonged work time; 4) considerable use of materials. Such a type of manufacturing method therefore becomes very complicated and expensive, while also involving the use of considerable amounts of materials to make the various parts of components required for the particular construction. Therefore, it is a purpose of the present invention to eliminate the disadvantages cited in the foregoing in the eyeglass manufacturing processes by providing a method of manufacturing eye glasses of a self-styled type that is capable of producing glasses of different types, shapes and sizes with a) few and simple phases of work, b) a reduced use of labor force, c) considerably shorter work times, d) decrease the use of raw materials, materials and auxiliary and secondary products , e) minimization of any possible type of wear and tear. This method of manufacture is obtained with the operational phases that are described substantially, with particular reference to the rei indications annexed to the present patent. The invention will be better understood from the following description, given only by way of non-limiting example, and with reference to the accompanying drawings in which: Figure 1 shows schematically a front view of a first operational phase of the present manufacturing method and a relative tool used, - Figure 2 shows schematically a front view of an intermediate product obtained from the present method, on a constructive version thereof, during the second phase 'operative of the present manufacturing method; Figure 3 schematically shows a plan view of a tool used during the second operative phase of the present manufacturing method. - Figure 4 schematically shows a front view of an intermediate product obtained in the third subsequent operative phase of the method > Referring, in a different constructive version of the same, - Figure 5 shows a plan view of the intermediate product of Figure 4, - Figures 6 and 7 show a front sectional view of the article of one of the component parts used for the intermediate product of Figure 4, in two different versions thereof, - Figures 8 and 9 show a sectional plan view of the article of the same component part used, in two additional constructive versions thereof, - the Figures 10 and 11 show a side view in respective section and front view of the same component element of Figures 8 and 9, in a different construction version thereof, - Figure 12 shows a side sectional view of the same component element in an additional constructive version thereof, Figure 13 shows a front view of another component part used to manufacture the glasses, - the Figures 14 and 15 show a sectional side view of the component part of Figure 10, before and after having been fitted to the product. The Figures listed in the foregoing illustrate schematically the various operative phases of the methods of manufacturing glasses according to the invention, which is capable of producing in a very simple manner eyeglass lenses of both innovative and traditional types, these they are usually formed by a frame, a pair of lenses to see (in the case of eyeglasses for sight) or darkened lenses (in the case of sunglasses) a pair of lenses to see particular or treated (in the case of protective or sportive eyeglasses) as well as a pair of support bar or other glasses that support elements provided on the sides or on the upper part of the frame, as well as to be able to rest on the ears or head of each person, along with a simple element or a pair of elements or more that act as the nasal piece and intended to allow the glasses to rest on the nose of each person. In view of producing the above mentioned component eyewear parts of different type, shape and size, according to the use of the present invention, they can be made of at least one thin section bar of preferably metallic material, and particularly, but not exclusively aluminum, either natural or anodized on its surface, or also light alloys of other materials having low weight and cost, and further advantageously it is either notched or chamfered in a conventional manner along one side thereof in a rectilinear direction for the complete length of the section bar, the section bar that is commonly available as parts or rolls of different length and that is cut in increment over portions of the same length, in such a way as to obtain the relative framework as will be described later. In addition, the method is also required for the bars (arms) and the elements that rest on the nose to be produced separately, each time according to the particular models, that is, special or standard, to be manufactured in accordance with the marked requirements, in view of being then able to apply it subsequently on each front part of the spectacle frame manufactured with the method considered in the manner that will be described in the following. The manufacturing method according to the present invention is carried out by performing a sequence of operational phases in which at least two portions of wire, marked with the reference numbers 15 and 16 are employed, which have either the length identical or different from each other depending on the size of the frame to be obtained, and the end portions of which are inserted and suitably fixed removably within suitable pairs of centered and closing elements 17 and 18, in a shape extending over a horizontal direction and arranged aligned with each other on the same vertical plane, in a position that is reciprocally superimposed and spaced. In addition, two patterns or templates 19 and 20 which are spaced apart and horizontally aligned with each other, are interposed in the space comprised between the wire portions 15 and 16 so as to configure the wire portions with the same shape and size which it is slightly longer than the lenses, screens, filters and the like that will be respectively used for each type of glasses, in a way that the portions thus configured can be subsequently adapted thereto. Such templates are supported by an associated support (not shown), in a way that is able to adjust from time to time the required extension in the axial space between them, and an adjustment in the aforementioned example, is performed by alternately sliding the support of each template in a corresponding rectilinear slot with the horizontal extension (not shown) that can obviously also be effected in different ways in such a way that it always achieves the same function referred to. These templates are respectively profiled with a top-bending half portion 21 and 22 extending on one side with a rectilinear horizontal portion 23 and 24, and with a lower half-fold portion 25 and 26 extending on one side with a portion thereof. 27 and 28 horizontal short line identical and coincident Xon the corresponding horizontal portion of the associated upper fold portion 21 and 22, and on the other side is attached to the latter by means of a respective vertical rectilinear short portion 29 and 30. In addition , these insoles are symmetrical with each other in a way that each pair of coincidental horizontal portions is rotated in an opposite direction with respect to the remaining pair of the horizontal portions, and that the vertical portions 29 and 30 are rotated together and arranged approximately with each other . In order to allow each wire portion to be adapted on these templates it is centered on the latter in a form that they insert themselves into the notch or chamfer of the wire portions during the first operational phase of the present manufacturing method. Finally, whenever referring to Figure 1, it is observed that the wire portions 15 and 16 and the pattern 19 and 20 cooperate with a shaped tool visibly constituted by at least one die formed by a first die half 31 and a second half of lower die 32, which are respectively located above the first wire portion 15 and below the second wire portion 16, in a position in contact with the corresponding wires and aligned with respect thereto in the patterns , the first and second die halves that are configured with the same contour of the corresponding upper bending portions 21 and 22 and the lower bending portions 25 and 26 as well as also horizontally 27, 28 rectilinear of the relative pattern 19, 20 and with a horizontal flat contour at the level of the respective vertical portions 29, 30 of the upper and lower bending portions, in the latter case provided by the part of a frame ion as will be described later. In the first operative phase of the method according to the invention, still referring to Figure 1, it was observed that the first and the second die half 31 and 32 are operated contemporaneously in a known manner, from their initial high position of the Figure 1 firstly in an approximate relation to each other, with an adjustable segment with conventional means, in order to closely enclose the assembly of wire wire portions, thereby arranged for configuration of two half frame portions 33 and 34, which are respectively the upper and lower half portions that assume the contour of the corresponding upper die 31 and the given lower half 32, and subsequently in a relationship that moves away from each other to return back to the position illustrated in FIG. Figure 1 in such a way that the frame portions 33 and 34 remain in the patterns can be extracted from this position and subjected s to the subsequent operative phase. In particular, such extraction was carried out using any of the different manual systems or a possible automatic mechanical means of the type known per se, which after the half frame portions have been extracted therefrom are provided to dispose it for the operational phase Subsequent to be described. The next second operative phase of the present method is performed with at least one apparatus shown in Figure 3, in order to couple the rectilinear contour of the frame to the convex contour of the lenses toward which it will subsequently be fixed, and it was called the configuration phase of menus.

These apparatuses are composed of a die formed by first and second die halves 37 and 38, which are located in an opposite position to each other and coincident with each other at the level of the two longitudinal sides that are opposite to the frame and configured with contours which are completely and perfectly coupled to each other, and identical to the outline of the lenses, screens, filters and the like, as well as those of the central joint pieces. In addition, such die halves 37 and 38 are formed by mobile component parts, capable of changing the distance between the lenses, screens, filters and the like, and being adaptable in lenses, screens, filters and the like with different and varying size and shape. This die is operated from an open starting position, evidently from Figure 3 in which the two given means 37 and 38 are open and arranged to accommodate the half frame portions between them, to a closed position (not obvious ), in which such half frame portions are attached by the given means with consistent configuration in the required contours thereof, and vice versa.

Figure 2 shows an intermediate product made in a constructional version thereof and configured of the trapezoidal shape. Of course, according to the invention it is also possible to use apparatuses of a different type than that described only by way of example, with the condition that it always implies carrying out the operative phase identical or similar to that described in, and claimed in the present patent. Turning now to Figures 4 and 5, an intermediate product obtained in the subsequent third operative phase of the present method is shown, whose product in the example shown is made in a constructive version with a different form with respect to that of Figure 2, particularly an elliptical rather than a trapezoidal shape, like that shown in Figure 2. In this third operative phase, in particular, the corresponding pairs of the rectilinear horizontal portions of the half frame portions 33 and 34 are joined together without the need for welding , by a respective hinge block 39 and 40, shown in different versions thereof in Figures 6-11 that are provided for the bar hinge. In particular, such arms or bars are configured with an extended rectilinear portion 41 that at its extreme articulation portion at any bend in the form of a curvature 42, or is shaped rectilinear in a conventional manner, and these arms or bars are Manufactured with different shapes, types and sizes when using traditional type appliances or are also specifically designated. In turn, the hinge blocks that are formed as will be described also when using apparatuses either of traditional type or designated specifically for the use, and they will be in any way in all cases in such a way that they are capable of receiving and accommodating the corresponding spigot of the bar. These hinge blocks are joined in position by means of adhesion material of the traditional type such as cements, adhesives, resins or also fastening means of the traditional type (screws, etc.). In the example illustrated in Figure 6, it was observed that each hinge block is constituted by a sheave 43 with a rectangular configuration that can be adjusted to each pair of rectilinear horizontal portions and therefore is provided with an internal cavity 44 opened in a side thereof, so as to facilitate these horizontal portions to be inserted therein, and closed on the other side thereof by means of a button 45 in which a through hole 46 for the passage of a screw 47 or the like is provided. , so as to lock the sheave to the corresponding rectilinear portions. In addition, such sheave is integral with either a hinge, fixed joints or similar of the traditional type, or some articulation members or levers of the type known per se (not shown) for articulation of the corresponding bar. In Figure 7 it is observed that each hinged block is always constituted by a sheave 43, adaptable to the corresponding rectilinear horizontal portions, however in this case it is not provided with a through hole and a screw and fixed by means of glue thereto. portions. In Figure 8 it is noted that each hinge block is always constituted by a sheave 43 with a through hole 46 and a clamping screw 47, whose sheave in this case is configured with a supporting structure 48 orthogonal thereto, provided with a transverse bolt 49 by the articulation of a corresponding rod 50, whose bolt is inserted in a corresponding through hole 51 of the same rod. In Figure 9 it is seen that each hinge block is constituted similar to that of Figure 8 and differs from it in that the sheave 43 is not provided with a through hole and a clamping screw and is stuck in a position similar to the Figure 7 and that the bar 50 instead of having a through hole 51 is configured with a curvature 42 in the portion thereof that is hinged to the frame, whose curvature is consequently hooked directly to the transverse pin 49 (spigot engagement system). . In Figures 10 and 11 it is noted that each hinge block is provided with a recess 52, which can be inserted in each pair of rectilinear horizontal portions of the portion halves 33 and 34, and extending towards the configured user's face as a U-shaped configuration, the button 53 of the U being turned outward and bent slightly inward at its free end portion 54, for the rod retention splice in the fully open position thereof. A pin-like pin indicated at 55 is fixed by riveting at its ends on the two wings of the U-shaped configuration. The curvature 42 of the bar is then pivotally engaged about the pin with the maneuver indicated in Figure 10, which facilitates that the bar moves from the position 10b, as indicated by the dotted lines in the cited figure, and as is made possible by the frame 56 before the lenses, glasses, etc., are mounted therein, through the position 10a, through the front part of the spectacle frame again indicated with dotted lines, to the direction 10c indicated with solid lines, by means of a rotation according to the arrow B. ün pin 56 fills the U-shaped cavity 58 of the hinge block, so that it reconstitutes the convex surface of the curvature 42 and adheres thereto, in such a way that it is facilitated that the bar continuously maintains the position which is each time impa rtida to this, in particular, the position in which it is convenient to adhere to the templates of the user, so it ensures that the glasses by themselves remain tight in the head and do not slide down the nose, and also, to prevent the same bar from possibly breaking down or breaking, even after a prolonged period of use, as this on the contrary tends to happen very frequently with spectacles of the traditional type. This is effective in enabling the well-known disadvantages encountered with glasses bars of usual design, in which the articulated joint thereof can be repaired to gradually work by itself, loose and loose so that the bars, left in a loosely condition, They are no longer able to maintain any stable position and start freely to oscillate to be effectively avoided. For the purpose of the present invention, the material of which the pin is substantially made will be a rigid one. In Figure 11 another mode is illustrated, wherein the pin 57 instead of being made of substantially material is made of an elastic material., such as rubber, artificial rubber, synthetic resins, so that the bar, when the glasses are applied to the face of the user, is able to move elastically from position 12a (full lines) to position 12b (dotted lines), while there is the elastic pressure of the new pin visibly deformed, which acts as a shock absorber, which keeps the bar adhered against the head and, therefore, improves the adaptability thereof to the head of the only users, so So much is added to the well-being of wearing glasses without having to use expensive elastic hinges to achieve this purpose. Obviously, the hinge blocks described by way of example may also be made in different forms, with the proviso that they can join both of the half frame portions without the need for welding, in this way without departing from the scope of the invention. Therefore, to the product thus obtained the bars are applied to the hinge blocks provided for the bar hinge. These bars 50 are joined in position by means of fixing joints and bolts or similar articulation means, in the case in which the frame is provided with either conventional hinges or articulation members or levers of the type known per se. The operations of application of the bar can be carried out either manually or by means of suitable automatic devices. In the four subsequent operational phases of the present manufacturing method, the mutually reinforcing and assembled bars are thus caused to appropriately undergo the chemical treatment process of a type known per se for protection, cleaning and surface finishing purposes, adapted to confer the necessary properties of arti - cros ons and resistance to the materials used, in such a way that all the above make it possible to comply with the sanitary requirements and the health rules, as well as to produce the color, the decoration, the finish and the general aesthetic effects desired. In this case it is also possible for the protection and finishing treatments to be removed from the current glasses manufacturing processes, preferably by using during this operative phase of the process, the materials that have been subjected to these treatment directly, by means of the supplies of the same materials, and therefore, supplied in a pre-finished condition to the eyewear manufacturers. In the fifth subsequent operative phase of the present method, the respectively used lenses are then inserted into each frame either manually or automatically by means of appropriate automated equipment. On the lenses that have also been inserted, the complete set is hermetically pressed together with an appropriate shape, in such a way that it completes the assembly of each type of glasses. In this case the use can be made according to the current needs and scope of use, of lenses of various types, shades and colors, for either lenses to see or sunglasses, lenses for presentation or advertising, etc., as well as well as protective lenses and / or screens of various types, filters, etc., for use in the most varied areas of application, such as, for example, workshops in factories, offices, sports and leisure, etc. In addition, the bars are equipped with the related finished parts that are available separately and are for this purpose slidable on the same bars, again manually or by means of the appropriate automated equipment. Keeping in their position together each of such frames, under the resulting lock in position of the lenses, screens, filters, etc. , used in this way to complete the spectacles, is carried out by using preferably a suitable separate clamping piece 59 made of plastic material (see Figures 13-15), in the form of a central body 60 provided with a rectilinear recess 61 capable of being snapped onto the connecting piece 62 of the related frame and clamped on the same piece by means of a counter-clamp 63, the clamping piece being furthermore so formed that represents two lateral handles 64 and 65 that extend downwards from the central body and are configured that are able to fit in the nose of each person. It will be appreciated that, instead of using the clamping piece 59 to act as a single piece resting on the nose, the possibility also exists for two or more pieces resting on the nose of various types, readily available in the market for this purpose, which are in any way capable of maintaining the frames in position together with a similar operation or also with possible fixing means or of the type known per se, in this way without departing from the field of protection of the present invention. At this point, the advantages of the method of manufacturing glasses according to the present invention are completely clear and can be summarized as follows: 1. minimization of the points of damage; 2. the construction of the glasses does not require welding and possibly without the use of screws; 3. use of raw materials that have never been or at least almost never been used before in the manufacture of glasses (such as aluminum, copper and various alloys, etc.), 4. use of an articulation joint (spigot) that it is totally different from the joints used so far; 5. the simplified assemblies of the various component parts of the glasses; 6. The modular construction of the glasses allowing for all of the elements of the same will be easily interchangeable, that is, replaced in a simple, elementary way (due to either breakage, adjustments, or even for adaptation to change models or personal requirements ); 7. the drastic reduction in manufacturing costs of each component part of the glasses; 8. elimination of dependence on individuals for repairs, services or similar, thanks to the ease of ways in which the various elements can be replaced (assembled directly by the client); 9. variation of the models when exchanging different parts or component parts of the glasses; 10. reduction of time in requirements work as well as in the need of operational phases; 11. improved structural strength of the glasses, thanks to the complete elimination of welding - and the possibility of also eliminating the screws or the equivalent means to them; 12. the diminished use and, therefore, great savings of the materials used, due to the use of chamfered wire which is used integrally in each frame thus produced in such a way as to eliminate the wear; 13. the use of pre-treated materials in such a way, removing the need for corresponding surface protection and finishing treatments of any kind to be carried out in the industry; 14. greater security assured in • the various conditions of use.
