Description
METHOD FOR PROVIDING COMPONENTS OF FRAMES OF EYEGLASSES AND COMPONENTS OBTAINED WITH SUCH METHOD
The present invention relates to a method for providing components of frames of eyeglasses and the components obtained with such method.
Nowadays frames of eyeglasses are known which are made of metallic material or of plastic material, transparent or colored.
The components of the plastic frame are typically produced by milling or by injection molding.
In the method involving milling a computer-controlled machine forms the shape of the component from sheets of colored plastic, of greater or lesser thickness. Usually the blanks thus obtained are then sent to subsequent refinishing work.
With this method various parts of the eyeglasses are formed, i.e. the front, the temples and sometimes even the nose pads, which are thus assembled and finished.
In the production method involving injection molding the liquefied plastic material is injected into the mold bearing the final impression of the component to be produced.
Both methods are very widespread and make it possible to produce eyeglasses frames made of transparent or colored plastic, either single- colored or with a limited variety of possible patterns. Neither of the two methods in fact make it possible to obtain patterns like those of, for example, colored fabrics or papers, or a tactile or visual effect similar to that of fabric.
The aim of the present invention is to provide a method for providing components of frames of eyeglasses with particular effects of pattern and materials, which cannot be achieved with conventional methods.
Within this aim, an object of the invention is to provide a method with which to provide components of frames of eyeglasses which are structurally
strong.
This aim and this and other objects which will become more evident hereinafter are achieved by a method for providing components of frames of eyeglasses, characterized in that it comprises the following steps:
- superimposing on the impression of a die, in the following sequence, at least one first fabric, at least one first layer of glass or carbon fibers, at least one fabric made of glass or carbon fibers, at least one second layer of glass or carbon fibers and at least one second fabric, at least one of said at least one first fabric and at least one second fabric being impregnated with resin,
- closing and heating of the mold with application and holding of the temperature and of the forming pressure, until complete polymerization of said resin occurs, said mold bearing said substantially flat impression,
- opening said mold and extracting the manufactured article from said mold,
- cutting said manufactured article so as to form said component or a semifinished blank thereof.
Furthermore, the invention also relates to the components that are made according to such method, which are characterized in that they comprise a front or temples of such frames of eyeglasses.
Further characteristics and advantages of the invention will become more apparent from the description of a preferred, but not exclusive, embodiment of the method and the components according to the invention, which are illustrated by way of non-limiting example in the accompanying drawings wherein:
Figure 1 shows, in one step of the method according to the invention, the combination superimposed on the impression of the die;
Figure 2 shows the manufactured article extracted from the mold; Figure 3 is an enlarged view of a portion of the manufactured article in Figure 2, with its superimposed parts sectioned and exposed;
Figure 4 shows the manufactured article during the cutting step of the method according to the invention;
Figure 5 shows the manufactured article at the end of the cutting step of the method according to the invention;
Figure 6 shows the component obtained by way of the method according to the invention;
Figure 7 shows a second embodiment of the manufactured article.
With reference to the figures, the method according to the invention comprises a step of superimposing on the impression 11 of a die 12a, in the following sequence, at least one first fabric 13a, at least one first layer of glass or carbon fibers 14a, at least one fabric made of glass or carbon fibers 14c, at least one second layer of glass or carbon fibers 14b and at least one second fabric 13b.
A complementary die 12b, designed to close against the die 12a, completes the mold 12 shown in Figure 1.
In particular, as is evident from Figures 1 and 3, the superimposition step creates a sandwich-like structure 15, according to which a central layer 16, comprising the fabric made of glass or carbon fibers 14c between the first and the second layers of glass or carbon fibers 14a and 14b, is closed between a first multilayer of fabric 17a and a second multilayer of fabric 17b.
Each layer of glass or carbon fibers, first 14a and second 14b, has respective fibers oriented in a single direction.
In particular, in the present embodiment, which is described herein by way of non-limiting example of the invention, the first and second layers of glass or carbon fibers 14a and 14b are arranged with the respective fibers oriented in the same single direction.
It should be noted that in other embodiments, not shown for the sake of simplicity, the layers of glass or carbon fibers, first 14a and second 14b, are arranged with the respective unidirectional fibers oriented in different
directions from one layer to the next.
The first multilayer of fabric 17a comprises two layers of the first fabric 13a and the second multilayer of fabric 17b comprises two layers of the second fabric 13b.
Conveniently, the fabrics 13a and 13b are impregnated with resin, preferably synthetic, of the epoxy or acrylic type or biological natural or bioplastic or food-derived.
Again according to what is shown, this particular example shown also involves the use of a first and a second film of plastic material, respectively 18a and 18b, of the polyamide or polyethylene or bioplastic type.
In particular, the superimposition step initially involves the application of the first film of plastic material 18a on the impression 11 , which is followed by the other layers listed above, over all of which the second film of plastic material 18b is finally superimposed.
In this manner the sandwich-like structure 15 is covered, at the first and second multilayers of fabric 17a and 17b, respectively by the first and second films of plastic material 18a and 18b.
In the second step of the method according to the invention, the mold 12, which bears a substantially flat impression 11 , is closed and heated, applying and holding a specific temperature and a specific forming pressure for the entire time that it remains closed, i.e. the time necessary for the resin to migrate to the other layers and completely polymerize, in this manner gluing them to each other.
Subsequently the mold 12 is opened and the manufactured article, designated with 19 in a first embodiment thereof, is extracted from the mold 12.
Finally the manufactured article 19 is cut so as to form the component
10.
Figure 2 shows the manufactured article 19, on which a portion A is cut; the enlargement of this portion in Figure 3 highlights the parts
described above.
The example is a manufactured article 19 from which a series of eyeglass frame fronts will be obtained, which will therefore not lack the seats for the lenses.
In fact, as shown in Figures 4 and 5, the cutting step substantially involves cutting and extracting the parts from the manufactured article 19 which will be occupied by the lenses of the eyeglasses and subsequently complete the shape of the component.
The impression 11 of the mold 12 is substantially flat and has a substantially U-shaped cross-section, which has a central hump 20 which extends along the entire length of of the impression 11 and creates a central shape 21 of the profile of the manufactured article 19, corresponding to the bridge 22 of the component 10, i.e. the front of the frame, designed to rest on the nose.
More specifically, the manufactured article 19 advantageously comprises a central portion 23 from which the front of the frame is obtained and also comprises two lateral portions 24, which correspond to the parallel parts of the U-shaped profile of the impression 11 , from which the couplings 25 of the front for the hinges with which the temples are to be assembled to the frame are obtained.
By conveniently modifying the cross-section of the impression it is possible with the same method to obtain not only the fronts but also the temples of the eyeglasses frames.
As illustrated in Figure 6, the component 10, i.e. the front of the frame, comprises two seats 26, or rims, for the lenses and the bridge 22, which is contoured according to the central shape 21 of the profile of the manufactured article 19.
In a second embodiment of the component according to the invention the impression is without a central protuberance and thus produces a manufactured article 119 with no central shape for the bridge of the front.
It should in fact be noted that on the basis of the requirements, by modifying the shape and size of the impression but following the same method it is possible to obtain components (and thus fronts) of different shapes and sizes, for example lacking the lower part of the rims for the lenses, or smaller or bigger according to the design measurements for the frame.
It should be noted that the component can be made with a central layer 16 made of glass fibers or carbon fibers, according to requirements, and this layer combines with the fabrics 13a and 13b to ensure the desired structural strength.
Moreover, as can be seen from Figures 1 and 3, the layers of glass or carbon fibers 14a and 14b are superimposed so that those fibers are arranged in the component 10 along the direction of the prevailing dimension, which in this case runs from one coupling 25 to the other of the front.
This contrivance ensures greater strength of the frame in resisting bending.
It should also be noted that the fabrics 13a and 13b can advantageously be linen, cotton or other natural materials, which give the product a more natural appearance than the models on the market.
Moreover such fabrics 13a and 13b can bear particular patterns which remain visible after production is finished, being covered with a substantially transparent film of plastic material 18a and 18b, or the latter can itself be colored according to the pattern desired by the manufacturer.
The application of the films of plastic material 18a and 18b gives the product a clear appearance, but these can also be omitted, or they can be applied on one side only of the manufactured article, so that the purchaser will also perceive the natural tactile effect of the fabric.
Moreover the color of the frame can also be obtained with the application of sublimatic or non-sublimatic films in the mold or, on the finished product, by way of pad printing, spray painting, thermal printing
and sublimation.
In practice it has been found that the invention fully achieves the intended aim and objects, by providing a method for providing components of frames of eyeglasses that have particular pattern effects and at the same time are structurally strong.
The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.
In practice the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
