Description

Spectacle frame comprising a hybrid main frame

The present invention relates to the field of eyeglasses and eyeglass frames and, more particularly, so-called “rimless” frames which surround the peripheral edge of the lenses.

Classically, a pair of glasses consists of a spectacle frame in which sunglasses, sight or fancy lenses are fitted. The spectacle frame comprises a main frame adapted to receive said lenses, and two branches mounted at the lateral ends of said main frame. Each branch is connected to the main frame via a hinge which mainly allows the branch to be folded/unfolded. In addition, the main frame has a nose bridge on which adapted nose pads are mounted to improve the comfort of the user when wearing the frame. In practice, the nose bridge is formed in the same material as the main frame, in particular in acetate, while the nose pads are in another material and fixed by gluing according to various more or less long and restrictive processes.

A spectacle frame being a fashion accessory, it is necessary to design a large number of frame models in order to satisfy all the desires of users, which has a drawback. One of the disadvantages of a traditional frame is that it is generally made of a single material (acetate, metal, etc.). In order to provide an improved aesthetic effect, it is desired to be able to produce a main frame comprising several different materials. An obvious solution to achieve this result will be to use a main frame in a single material, comprising two circular openings in which the glasses are mounted, and to provide ornaments made in other materials which would be attached to the main frame by gluing. or clipping. This is known in particular from the patent application FR3059791. Such a solution overloads the aesthetic appearance of a frame and allows only a slight modification of the aesthetic appearance.

The object of the invention is therefore to remedy at least some of these drawbacks by proposing a new frame whose assembly is easy and whose appearance can be adapted in a practical manner while having a reduced manufacturing cost.

PRESENTATION OF THE INVENTION

The invention relates to a spectacle frame comprising a main frame comprising two openings capable of receiving two lenses respectively, each opening comprising an inner peripheral edge capable of cooperating with an outer peripheral edge of a lens.

The frame is remarkable in that the main frame comprises at least a first portion and a second portion which are connected together in a removable manner, each portion forming a distinct angular part of the inner peripheral edge so as to form a hybrid inner peripheral edge.

Advantageously, the strapping of the lens is made in a modular way in order to be able to modify the aesthetic aspect of the frame in depth and in a refined way. It is not necessary to add add-ons to the main frame. It is the main frame as such that is advantageously modified, which goes against a common prejudice that it is only made of a single material. Due to its removable nature, the main frame can be modified in a practical way in order to make it evolve with the fashions of the moment. By hybrid, it is meant that the inner peripheral edge is formed of several portions which are independent and mounted in an attached manner.

Preferably, the first portion and the second portion are adjacent so as to extend consecutively to the periphery of the peripheral inner edge. In other words, one portion is not entirely positioned internally to another. The first portion and the second portion are angularly offset on the inner peripheral edge.

Preferably, the first portion is in a first material and the second portion is in a second material which is different from the first material.

More preferably, the first portion and the second portion are in different colors.

Preferably, the second portion extends partially internally to the first portion. Thus, the assembly advantageously allows continuity between the portions, which reinforces the mechanical assembly.

Preferably, the second portion comprises at least one projecting member which is mounted in a blocking cavity formed in the first portion. The use of a projecting member makes it possible to produce a mechanical assembly that can be easily removed. In addition, such mechanical cooperation makes it possible to take into account the manufacturing tolerances of the different portions and thus improves the assembly of heterogeneous materials.

Preferably, the protruding member is mounted in a blocking cavity by a fitting connection configured to be released when the second portion is moved closer to the first portion. In other words, in the event of traction induced by a glass mounted in the inner edge, the protruding member cannot be released. It is necessary to make an antagonistic effort, that is to say a compression, to allow a release. Such release is advantageously impossible in the presence of the glass.

Preferably, the blocking cavity is inclined at an angle relative to the normal to the inner peripheral edge near which it is located, the blocking cavity being inclined in the direction of the outside towards the end of the first portion so as to form a strong point of attachment. Such a blocking cavity makes it possible to form an attachment point so that the protruding member cooperates in the manner of a hook.

Preferably, at least the second portion is made of flexible material. Preferably, the first portion and the second portion are made of flexible materials. A soft portion is technically very advantageous as it can conform to different lens shapes. It is thus possible to assemble original frames for glasses of different shapes from flexible portions which are identical. Thanks to the invention, flexible and rigid portions can be associated together, which offers significant flexibility for opticians.

Preferably, a portion comprises a nose bridge, this portion being made of a rigid material so as to ensure the stability of the frame when it is worn, in particular, it provides geometric support for the pair of glasses.

According to one aspect of the invention, the first portion and the second portion are angularly separated from each other so as to form an angular discontinuity of the inner peripheral edge. Such a spacing makes it possible to form a continuous banding in pieces which makes it possible to retain the glass optimally with portions made of different materials.

Preferably, the main frame comprises a connecting element, removably mounted, mechanically connecting the first portion and the second portion, the connecting element extending at a distance from the inner peripheral edge. Such a connecting element makes it possible to connect portions by stapling in order to connect portions made of different materials.

Preferably, each portion comprising an inner wall facing the opening of the glass and an outer wall opposite the inner wall, the connecting element is mounted between the outer wall of the first portion and the outer wall of the second portion . Such a connecting element is simple to mount for an optician.

Preferably, the connecting element extends in the extension of the outer wall of the first portion and of the outer wall of the second portion.

Preferably, the connecting element comprises at least a first projecting member which is mounted in a blocking cavity formed in the first portion and at least a second projecting member which is mounted in a blocking cavity formed in the second portion.

Preferably, the protruding members are mounted in the blocking cavities by interlocking connections configured to be released when the second portion is brought closer to the first portion, that is to say, for a compression force.

The invention also relates to a pair of spectacles comprising a frame as presented above and at least one lens mounted in said opening, the outer peripheral edge of the lens being in contact simultaneously with the first portion and the second portion forming the hybrid inner peripheral edge .

The invention also relates to a method for mounting a main frame of a spectacle frame as presented previously, the main frame comprising at least a first portion and a second portion which are connected together in a removable manner, the method comprising a mechanical assembly of the first portion with the second portion so as to form a hybrid peripheral inner peripheral edge, each portion forming a distinct angular part of the inner peripheral edge.

• un assemblage mécanique de la première portion avec la deuxième portion de manière à former un bord périphérique intérieur périphérique hybride, chaque portion formant une partie angulaire distincte du bord périphérique intérieur et
• une étape de montage du verre dans le bord périphérique intérieur de manière à tendre la deuxième portion en matériau souple sur le verre.

The invention also relates to a method for mounting a pair of spectacles as presented above, the main frame comprising at least a first portion and a second portion which are connected together in a removable manner, the second portion being in a flexible material, the method comprising:

• a mechanical assembly of the first portion with the second portion so as to form a hybrid peripheral inner peripheral edge, each portion forming a distinct angular part of the inner peripheral edge and
• a step of mounting the lens in the inner peripheral edge so as to stretch the second portion of flexible material over the lens.

Thanks to the invention, the frame is stiffened during the assembly of the lens which makes it possible to stretch the flexible portion or portions in order to form a pair of glasses. The use of a flexible portion makes it possible to adapt to any shape of lens, which is advantageous and limits the cost of manufacturing a frame.

DETAILED DESCRIPTION OF THE INVENTION

Referring to Figure 1, there is shown a full-rimmed frame 1 comprising a main frame 2 comprising two openings 3 capable of receiving lenses respectively (not shown). Such a rimmed frame 1 is opposed by nature to a frame of the Nylor type or to a pair of rimless glasses. In this example, each opening 3 comprises an inner peripheral edge 30 capable of cooperating with an outer peripheral edge of a lens. Such an opening is also known to those skilled in the art under the designation of strapping. The frame 1 has two arms 5 and a nose bridge 8 supporting two nose pads or the like to ensure the support on the nose. The main frame 2 has a rear face intended to be turned towards the user and a front face opposite the rear face.

Subsequently, for the sake of clarity and conciseness, a main frame 2 will be described which has vertical axis symmetry Z as illustrated in FIG. 1. In other words, the inner peripheral edges 30 of the openings 3 are symmetrical. Also, it will only be described below the inner peripheral edge 30 of a single opening 3, also called strapping. Nevertheless, it goes without saying that the invention also applies to a main frame 2 which is not symmetrical and whose inner peripheral edges 30 of the openings 3 are different.

According to the invention, the main frame 2 comprises at least a first portion 21 and a second portion 22 which are connected together in a removable manner. The portions 21, 22 are rigid or flexible. Each portion 21, 22 forms a distinct angular part of the inner peripheral edge 30 so as to form a hybrid inner peripheral edge 30, that is to say, formed from different materials. Each portion 21, 22 has a groove, known as a bezel for those skilled in the art, in order to cooperate with the glass. A groove is inherently concave to receive a convex edge of the lens.

Preferably, at least a first portion 21 is in a first material and a second portion 22 is in a second material, different from the first material. According to one aspect, the two portions 21, 22 are in the same material, in particular acetate, but in different colors. The material can be chosen from acetate, metal, wood, glass, acrylic, nylon, polymers, elastomers, silicone, minerals, etc.

A portion 21, 22 made of flexible material, for example soft plastic, elastomer or nylon, is advantageous given that it can match the shape of different glasses and thus finds a more universal application than a rigid portion. As will be presented below, when using portions in a flexible material, the frame remains rigid due to the mounting of the lens which is, by nature, rigid. After assembly, the frame 1 and the lenses together form the pair of glasses.

The main frame 2, flexible in part or in whole, hugs the outer peripheral edge of the glass, which stretches the main frame 2 which becomes rigid. Preferably, the main frame 2 comprises a central portion which comprises a nose bridge and which is made of a rigid material. This ensures a transition between the side parts of the main frame 2 which are stiffened by the mounting of the glasses.

By way of example, with reference to FIG. 1, there is shown a main frame 2 comprising a first portion 21 which is central and comprises the nose bridge 8. The first portion 21 is in a first material, for example, of acetate, wood, metal, etc. The main frame 2 further comprises second portions 22 which are lateral to support the branches 5. Each second portion 22 is in a second material which is different from the first material. Preferably, the first portion 21 is in a rigid material given that it comprises the nose bridge 8. Similarly, the second portion 22 is in a flexible material in order to be able to adapt to glasses of different shapes.

Still with reference to FIG. 1, the inner peripheral edge 30 is formed by the mechanical assembly of the first portion 21 with the second portion 22 according to two interface points I1, I2: a top interface point I1 and a point low interface I2. Figure 2A is a close-up representation of the assembly at interface points I1, I2.

In this exemplary embodiment, the interface points I1, I2 are analogous. Also, for the sake of clarity and conciseness, only the high interface point I1 will be presented in detail.

As illustrated in FIGS. 2A and 2B, the first portion 21 forms an upper and inner central part of the peripheral edge 30 of the opening 3. The first portion 21 comprises a first groove 219 to form an angular part of the inner peripheral edge 30 of the opening 3. opening 3. The first groove 219 makes it possible to retain the glass in a stable manner. To this end, the first groove 219 preferably has a V-section. Preferably, the first groove 219 has a depth of between 0.5 mm and 3 mm.

At the level of the high interface point I1, one end of the first portion 21 comprises a housing 210. The housing 210 is formed at the end of the first groove 219, in particular, substantially in its extension.

As will be presented later, the housing 210 of the first portion 21 is deeper than the first groove 219 so as to be able to accommodate part of the second portion 22. Preferably, the housing 210 has a depth of between 1 mm and 6mm. Preferably, the housing 210 has a length greater than 1 mm in order to allow a robust and compact assembly.

As illustrated in Figures 2A and 2B, the housing 210 includes a blocking cavity 211 adapted to receive a projecting member 220 belonging to the second portion 22. In this example, the blocking cavity 211 is of frustoconical shape but it goes without saying that it could be of different shape.

Referring to Figure 2C, the blocking cavity 211 extends along an axis U which is inclined at an angle α relative to the normal N towards the outside towards the end of the first portion 21 so to form a robust point of attachment in the event of traction between the first portion 21 and the second portion 22, in particular, when fitting a lens. Preferably, the angle α is between 5 degrees and 90 degrees.

Still with reference to FIG. 2C, at the level of the high interface point I1, the second portion 22 comprises an end part 22A which comprises a projecting member 220 which, in this example, is in the form of a finger inclined. The end part 22A is configured to be mounted in the housing 210 while the projecting member 220 is configured to be mounted in the blocking cavity 211. In this example, the end part 22A has on its inner face a second groove 229, preferably of a shape similar to the first groove 219, in order to cooperate with the outer edge of a lens.

The projecting member 220 extends substantially along an axis normal N to the inner peripheral edge 30 near which it is located. Preferably, as illustrated in FIG. 2C, the projecting member 220 is inclined at an angle α, identical to that of the blocking cavity 211, with respect to the normal N in the direction of the second portion 22 so as to form a hook-like concavity to improve tensile strength.

As illustrated in FIG. 2A, at the level of the high interface point I1, the first portion 21 cooperates with the second portion 22 so that the blocking cavity 211 and the projecting member 220 fit together by complementarity. of shapes. The first groove 219 and the second groove 229 form a continuous groove defining the inner peripheral edge 30.

Alternatively, as illustrated in Figures 9A to 9C, the first portion 21 and the second portion 22 may comprise a projecting tongue 218, 228 which is mounted in a peripheral groove 48 formed in a lens 4 as illustrated in the cross-sectional views. U-U and V-V.

It goes without saying that the positions of the blocking cavity 211 and of the protruding member 220 could be reversed to meet manufacturing or material constraints.

Advantageously, such a mechanical assembly makes it possible to combine in a practical manner different portions 21, 22 in different materials and of different rigidities in order to create various aesthetic effects. Advantageously, an inner peripheral edge 30 is formed which is hybrid because it is formed from several materials. A mechanical assembly of the inner peripheral edge 30 overcomes manufacturing tolerances depending on the materials.

When mounting a lens in the inner peripheral edge 30, traction is exerted by the lens at the interface points I1, I2. Thanks to the assembly according to the invention, the connection is robust despite the fact that the materials are heterogeneous. The protruding member 220 is mounted in the locking cavity 211 of the housing 210 by a fitting connection configured to be released when the second portion 22 is brought closer to the first portion 21. In other words, a compressive force between the first portion 21 and the second portion 22 makes it possible to disassemble the main frame 2. When a glass is mounted, involuntary disassembly is prohibited. Thus, if a user wishes to change the appearance of his spectacle frame 1, one or more portions 21, 22 can advantageously be replaced.

Such tensile strength is also advantageous when one of the portions is made of a flexible material which is stretched when mounting the glass.

In this embodiment of Figure 2A, the first portion 21 and the second portion 22 extend in the extension of one another in a continuous manner to form the inner peripheral edge 30.

Preferably, the second portion 22 has a smaller section than the first portion 21 so as to avoid any assembly defect linked to heterogeneous materials. In particular, as illustrated in FIG. 2A, the outer surface of the main frame 2 has a relief forming a discontinuity at the level of each interface point I1, I2 between the first portion 21 and the second portion 22. Such characteristics make it possible to take into account the manufacturing tolerances between the portions 21, 22 during assembly.

Referring to Figure 3A, there is partially shown a main frame 2 consecutively comprising three portions 21, 22, 23 made of different materials. The second portion 22 comprises two protruding members 220 to hold together the first portion 21 and the third portion 23 respectively. The second portion 22 acts in this example as a connecting clip function.

According to one aspect of the invention, with reference to FIG. 3B, the second portion 22 is positioned under the first portion 21 and the third portion 23 so as to ensure the connection without being visible. In this embodiment, a compressible seal 24 is mounted between the first portion 21 and the third portion 23. The compressible seal 24 is mounted externally to the second portion 22 so as to conceal it. The use of a compressible joint 24, for example made of silicone, is advantageous given that it makes it possible to provide a compression clearance for assembling/disassembling the portions 21-23 between them, allowing the release of the second portion 22 following to the application of a compressive force. Such a second portion 22, of reduced length and concealed, makes it possible to put portions 21, 23 of different materials end to end. Only a thin compressible seal 24 is present between said portions 21, 23. In addition, the compressible seal 24 can advantageously fulfill an aesthetic function.

Analogously to previously, the second portion 22 has a smaller section than the first portion 21 and the third portion 23 as well as reliefs forming discontinuities at each interface point. It goes without saying that the sections and shapes could be diverse. The technical solution proposed by the present invention thus makes it possible to assemble a large number of portions to form an inner peripheral edge 30 which is aesthetic, scalable and robust. Preferably, the second portion 22 is in this example made of a flexible material so as to allow assembly play between two portions 21, 23 made of rigid material.

Alternatively, the first portion 21 and the second portion 22 are angularly separated from each other so as to form an angular discontinuity of the inner peripheral edge 30. In other words, the inner peripheral edge 30 is not continuous and the outer edge of the glass is not maintained at each point of its periphery.

Referring to Figures 4 and 5, the main frame 2 comprises at least one connecting element 6, removably mounted, mechanically connecting a first portion 21 and a second portion 22, the connecting element 6 extending away from the inner peripheral edge 30 and is not in contact with the glass when mounted in the opening 3.

As illustrated in Figures 4 and 5, each portion 21, 22 comprises an inner wall facing the opening 3 of the glass and an outer wall opposite the inner wall, the connecting element 6 is mounted between the outer wall of the first portion 21 and the outer wall of the second portion 22.

In this example, the connecting element 6 comprises a main body 60 which can be of various shapes, in particular flat (Figure 4) or tubular (Figure 5). Preferably, with reference to Figure 4, the main body 60 of the connecting element 6 extends in the extension of the outer wall of the first portion 21 and the outer wall of the second portion 22 in order to ensure discrete continuity between the portions 21, 22 in the manner of a staple.

Preferably, the connecting element 6 comprises at least a first projecting member 61 which is mounted in a blocking cavity 211 formed in the first portion 21 and at least a second projecting member 62 which is mounted in a blocking cavity 223 formed in the second portion 22. Similarly to above, the projecting members 61, 62 are mounted by interlocking connections configured to be released when the second portion 22 is brought closer to the first portion 21. Conversely , the assembly is very robust in the event of traction between the first portion 21 and the second portion 22, which is advantageous when mounting a lens and when tensioning a portion made of flexible material. The projecting members 61, 62 are preferably angled so as to form hooks improving the resistance to traction.

Alternatively, the first portion 21 and the second portion 22 may comprise a projecting tongue which is mounted in a peripheral groove formed in a lens. In this case, the connecting element 6 does not include a projecting tongue and does not extend into the peripheral groove.

A method for mounting a main frame 2 of a spectacle frame 1 will now be presented. As illustrated in FIG. 2B, the main frame 2 comprises at least a first portion 21 in a first material and a second portion 22 in a second material.

The method comprises a mechanical assembly of the first portion 21 with the second portion 22 so as to form a hybrid inner peripheral edge 30, each portion forming a distinct angular part of the inner peripheral edge 30.

Referring to Figures 2A and 2B, the projecting members of the second portions 22 cooperate with the locking cavities 211 of the first portions 21 so as to allow a direct assembly of the portions 21, 22 between them. Such a mechanical assembly is advantageous given that it makes it possible to tension a flexible portion of the main frame 2, that is to say, to apply a tensile force to a flexible portion of the main frame 2.

Referring to Figures 4 and 5, the projecting members 61, 62 of the connecting element 6 cooperate respectively with the locking cavities 211, 223 of the first portion 21 and the second portion 22 so as to allow indirect assembly portions 21, 23 between them.

After assembly, a main frame 2 is obtained comprising openings 3 whose inner peripheral edge 30 is continuous or continuous in pieces, according to a plurality of distinct portions. The inner peripheral edge 30 comprises an overall groove, generally continuous, which is formed in pieces between the different grooves 219, 229 of the portions 21, 22 made of different materials from the main frame 2.

The optician then performs a step of mounting a lens in the opening 3 by cooperating the outer edge of the lens with the inner peripheral edge 30. The mounting of the lens is performed in a manner similar to the prior art, which is convenient. The second lens is mounted in the frame in a similar manner.

As indicated previously, the main frame 2 can comprise one or more flexible portions 21, 22 and as a result the frame is not rigid as such. When fitting the lenses in the frame, the flexible portions of the main frame 2 are stretched over the lenses, which gives the pair of glasses its overall and usual rigidity. Wearing the pair of glasses is thus pleasant for the user as in the prior art.

Thanks to the invention, a personalized pair of glasses can be fitted quickly and conveniently by an optician. The cost price of a frame is limited while multiplying the customization possibilities. The use of flexible portions makes it possible to produce the same frame that can adapt to glasses of different shapes.

It was previously presented a main frame 2 comprising only two different portions 21, 22 positioned respectively centrally and laterally. Nevertheless, it goes without saying that the portions could be arranged differently or have different shapes as illustrated in FIGS. 6A to 6D. In these examples, materials and colors can be freely modified.

Preferably, a portion 21 is common to two peripheral edges. Preferably, two portions 21, 22 are common to two peripheral edges.

In FIG. 6A, the first portion 21 comprises the nose bridge 8 and the upper part of each inner peripheral edge 30, the second portions 22 each forming the lower part of each inner peripheral edge 30.

In FIG. 6B, the second portion 22 comprises the nose bridge 8 and the lower part of each inner peripheral edge 30, the first portions 21 each forming the upper part of each inner peripheral edge 30.

In FIG. 6C, the second portion 22 comprises the nose bridge 8 and an inner central part of each inner peripheral edge 30, the first portions 21 each forming the upper part and the lower part of each inner peripheral edge 30. Each first portion 21 has an angular opening greater than 200 degrees, preferably greater than 300 degrees. Preferably, the second portion 22 is rigid while the first portion 21 is flexible.

In FIG. 6D, the first portion 21 comprises the nose bridge 8 and the inner peripheral edge 30 with the exception of the outer central part of each inner peripheral edge 30, the second portions 22 each forming the outer central part of each edge inner peripheral 30. Each first portion 21 has an angular opening greater than 200 degrees, preferably greater than 300 degrees.

Moreover, as illustrated in FIGS. 7A and 7B, the main frame 2 may comprise more than two different portions 21, 22, in particular 3, 4 or 5. This advantageously makes it possible to define a peripheral edge 30 which is multi-hybrid and formed of a plurality of different portions. This makes it possible to vary the materials freely and modularly.

In FIG. 7A, the first portion 21 comprises the nose bridge 8 and an inner upper part of the inner peripheral edges 30, of the order of 90 degrees. Second portions 22 each form an upper part of the inner peripheral edges 30, third portions 23 each form an outer upper part of the inner peripheral edges 30 and fourth portions 24 each form a lower part of the inner peripheral edges 30. Alternatively, as illustrated in Figure 7B, the second portions 22 can be joined by an arch 7 so as to facilitate assembly and provide an additional aesthetic effect.

Referring to Figure 8, there is shown a main frame 2 with significant modularity. Each inner peripheral edge 30 is formed of 8 different portions 21-28. It goes without saying that the different portions can be grouped in different ways in order to achieve the desired aesthetic properties. In addition, the portions 21-28 can comprise between two and eight different materials. Advantageously, the use of several flexible portions makes it possible to adapt to several shapes of glasses.

Thanks to the invention, an optician can assemble by himself, without special tools, a large number of main frames 2 of different aesthetic aspects in order to meet the needs of users. The shapes and materials can be adapted as desired to obtain a main frame 2 which is robust, in particular, following the assembly of the glasses.
