Description

Spectacles consisting of two annular frame elements connected by a nose bridge

The present invention relates to spectacles comprising two annular frame elements connected by a nose bridge, each annular frame element containing a lens, wherein each of the two annular frame elements is configured to be connected to an eyeglass side piece, preferably via a hinge unit , wherein the bridge of the nose is replaceable and includes a first coupling element at each end, the first coupling element cooperates with a corresponding second coupling element provided on each of the two frame elements, and wherein the first coupling element is The first and second coupling elements are configured for manual activation without the use of tools.

In general, when making spectacle lenses, it is important to be able to position the lenses optically and design correctly with respect to the user.

Therefore, when making eyeglasses, the correct positioning of the eyeglass lens with respect to the user's eye is important. When positioning the spectacle lens relative to the user's eye, even the slightest distortion or displacement risks visual disturbance. This is especially true for spectacle lenses with complexity.

The present invention relates to spectacles in which each spectacle lens is mounted in a frame element, so-called rimmed spectacles. Frame elements are also known in the industry as eyeglass frames.

The two frame elements are connected by a nose bridge. If the nose bridge is made to be securely connected to the frame element, the lenses will be spaced apart by a defined distance. This means that the glasses have a fixed interpupillary distance PD. Therefore, such glasses are only suitable for users with a certain interpupillary distance. Therefore, the optician must wear a large selection of spectacle frames, or alternatively must cut the spectacle lenses to be designed to fit a particular spectacle frame. This places high demands on professional measurements, where the precision depends on the care and skill of the individual optician.

The nose bridge is used to support the eyeglasses on the nose of the user, either directly by a nose bridge resting on the bridge of the nose in a manner almost comparable to a saddle on horseback, or by being mounted on the bridge and typically involving abutment with the bridge of the nose Or the bridge of the nose with spacers on both sides of the bridge of the nose. These gaskets are typically made of silicone.

Alternatively, the spectacles can also be supported on the nose of the user via a contact surface which forms part of the frame element. This contact surface may rest on the bridge of the nose or on both sides of the bridge of the nose.

If the nose bridge of the spectacles is supported directly on the user's nose, the lenses of the spectacles will be placed at a fixed distance from the user's eyes, and therefore at a fixed distance from the user's pupil. Thus, not only will the glasses have a fixed interpupillary distance, but the distance between the lens and the user's pupil will also be fixed. Therefore, the optician must wear a large selection of spectacle frames that take into account not only the pupillary distance, but also the anatomy of the user, where different nose shapes place these glasses at different heights with respect to the pupil.

Alternatively, the spectacle lenses must be cut to adjust to a particular spectacle frame. As mentioned above, this will place high demands on professional measurements, where accuracy depends on the care and skill of the individual optician. Furthermore, for better design reasons, it is desirable that the pupil center of the lens should preferably lie on the inner half of the spectacle lens with respect to an upright centerline running through the lens.

If the glasses rest on the user's nose via the nose bridge, there will be a certain possibility to adjust the distance between the lens and the pupil. Thus, the optician can place the lens at the correct distance from the pupil by selecting and/or adjusting the bridge of the nose. However, the optician still has to wear a spectacle frame adjusted to the interpupillary distance for each user.

By adjusting the bridge of the nose, it is therefore possible to adjust the glasses, eg with respect to the height or curvature of the nose, and to place the glasses in a position away from the face above the nose.

Such glasses are also known, where a nose bridge can be installed and removed to replace the bridge, for example in the case of damage or because the user wants to change the appearance of his glasses. These bridges are screwed to the frame elements and require tools for assembly and disassembly. This makes replacement cumbersome and involves the risk of breaking the threads when assembling the nose bridge and frame element.

Therefore, flexibility is required when adjusting the spectacles so that the optician can use the frame elements in the spectacles in a simple manner, by using noses with different designs (eg shape, colour, material or length connecting the two frame elements) Bridge, frame elements are individually adjusted depending on the user's anatomy. When replacing nose bridges, it is desired that the same frame elements can be adjusted to different anatomical structures.

GB 2410805 A describes glasses with a nose bridge that can be replaced without the use of tools, and is as defined in the introduction to claim 1. However, a rigid and torsionally stable structure is not described.

The basic purpose of the present invention is to make assembly, disassembly, replacement and maintenance of the nose bridge easy, flexible and simple, to allow adjustment of the spectacles without the use of tools depending on the anatomy of the user, and to establish a rigid and torsional stability connect.

Another object is to provide spectacles where it is possible to establish a connection between the individual parts of the spectacles with a clamping connection, ensuring that the coupling element of the nose bridge is stably positioned in the frame element after the lens has been mounted in the frame element.

Another object is to provide eyeglasses in which the eyeglass side pieces are mounted on the frame element using coupling elements similar to those of the nose bridge.

In other words, its purpose is to provide spectacles in which only manual labor is required to insert and remove the lenses, and in which the spectacle lenses constitute a locking function after being pressed into the frame element. Description of the invention

This aim is achieved by spectacles of the type initially mentioned, characterized in that the coupling element of each frame element comprises at least one first recess connected to a circumferential groove, through which the first recess penetrates, and in which the nose The coupling element of the bridge includes an adapter portion that is receivable in the recess and includes a slot connecting those ends of the slot formed by the circumferential slot through which the recess penetrates, and The circumferential slot in the frame element is restored when the coupling element of the nose bridge is installed in the recess, so that the nose bridge is retained in the recess when the lens is installed in the frame element.

The first coupling element can be retained by a press fit with other coupling elements, or by placing the first coupling element in a slot before the nose bridge is mounted to the lens, which slot makes a portion of its extension Below the slot in the frame element into which the lens is mounted, so that the nose bridge is held in the slot once the lens has been mounted.

Alternatively, the second coupling element may be formed by a slot in the side surface of the frame element, and the first coupling element may be formed by the U-shaped curved end of the nose bridge, the curved end is pressed into the slot and this curved end is held in the slot due to the elasticity of the U-shaped end. Alternatively, the retention can also be established using two locking elements, which cooperate by means of a snap effect or a hook function.

The cooperation between the two coupling elements ensures that the nose bridge rests stably on the frame element. It can be said that the glasses will self-lock without the use of tools.

Self-locking means that the elements of the glasses can be held without the use of screws, nails, rivets, cords or other loose parts commonly known for locking purposes.

The shape and size of the nose has a major impact on how the glasses rest on the face with respect to the eyes, and how the bridge of the nose passes through the nose. The large differences in nose appearance have implications for the design of the nose bridge. The replaceable nose bridge allows for the manufacture of spectacle variants, accommodating both tall, slender bridges, wide bridges and very flat bridges.

Therefore, it is simple for the optician to adjust the glasses to the anatomy of the individual user. Spectacle lenses are mounted in the two frame elements in the usual way by pressing into the lenses, and through the fact that the two parts have mutual flexibility, it allows the lenses to be pressed into and out of the frame elements.

The optician can select an appropriate bridge, whose length and shape are adjusted to the user's anatomy. The nose bridge can be attached to the two frame elements before or after the lens is mounted.

The nose bridge may be made of different materials, which may be the same as the material of the frame element or different from the material used for the frame element. A non-exhaustive list of materials includes plastic, metal, keratin, wood and fiber reinforced materials.

The easily replaceable nose bridge offers the optician several advantages: - Simple possibility to change the interpupillary distance by replacing the larger/smaller nose bridge; - Can be replaced without tools; - Possibility to choose nose bridges with different shapes adjusted to the anatomy; - Possibility to choose different coloured bridges; and - Possibility to choose a nose bridge of a different material than the frame element.

When customers need to try on glasses, they can decide in advance what bridge length and shape will be used. The customer can then choose the color and design.

As a result, opticians are able to provide a very high level of service with a small inventory.

In the frame element, it is relatively simple to form the recesses connected to the circumferential grooves that hold the lenses. By providing a recess connected to the slot, typically with a portion of the recess below the slot, the part of the adapter received in the recess can be designed with a slot corresponding to the slot in the frame element. By properly sizing the dimensions of the slot and the adapter portion, the slot will create an uninterrupted circumferential slot in the frame member after the coupling element of the nose bridge is installed in the frame member.

After this, placing the lens in the slot of the frame element and the slot of the coupling element of the nose bridge will ensure that the nose bridge remains in this slot.

Thus, this design will enable a rigid connection to occur in a simple manner by receiving the adapter element in a torsionally stable manner in the recess of the frame element. Thus, when the adapter part is located in the recess, the nose bridge and the frame element will establish a mutually rigid connection.

The slot formed in the frame element may be a slot having a bottom surface and two side surfaces, making it possible to receive a portion of the side surface area of the lens in the slot. This holds the lens in the slot.

The slot can be substantially U-shaped or V-shaped. The bottom surface can be of any shape and the transitions to the side surfaces can be sharp or curved partitions, however the side surfaces are necessary in the slot to prevent the lens from falling off the frame element.

In another aspect, the invention also relates to spectacles, wherein the spectacles are further characterized in that each of the two frame elements includes a ring, wherein the lenses are mounted and retained in circumferential grooves on the inside of the frame elements such that they can be manually Install and remove lenses by pressing them into and out of the frame element.

It is thus possible to assemble and lock the nose bridge to the frame element, wherein the locking takes place by pressing the lens into the frame element. Once the lens has been pressed into the circumferential slot, the lens will remain in the slot.

If the nose bridge is mounted in front of the lens and the first coupling element is located in the slot and has a portion of its extension below the circumferential slot in the frame element and the lens is mounted in the frame element, then once the lens has been mounted , the nose bridge will therefore remain in the slot.

The loops on the frame elements can be broken or unbroken. An unbroken loop means that the frame element is tied in one piece and there are no joints that can be opened/closed to insert a lens or nose bridge into the frame element. A broken loop means that the frame element may be made from more than one joint. The joints may be held together by fastening means including glue, screws or the like.

As mentioned, the frame element can be made of different materials, but is preferably made of metal or plastic or a combination of plastic and metal. This frame element has a certain flexibility in a known manner, which allows the lens to be pressed into or out of a circumferential slot in the annular frame element.

Circumferential grooves can be made in different shapes. It can take the form of a recess (groove) or protrusion (tongue) adapted to fit and receive the edge region of the lens, which has been adjusted to the shape of the slot.

In another aspect, the present invention also relates to spectacles, wherein the spectacles are further characterized in that the nose bridge is made of metal and establishes a rigid connection between the two frame elements.

Spectacles with frame elements made of plastic can be reinforced by making a nose bridge out of metal, which establishes a rigid connection of the two frame elements. Thereby, the spectacles can be made with a rigid structure, ensuring the correct positioning of the spectacle lenses with respect to the pupil of the user.

Rigid connection means the connection of two frame elements such that in normal use they will have a fixed mutual position.

In another aspect, the present invention also relates to eyeglasses, wherein the eyeglasses are further characterized in that a nose bridge is connected to two bridge bridges.

Preferably, the bridge of the nose is placed on the bridge of the nose. This allows the bridges and bridges to be replaced and adjusted to different anatomies. Alternatively, it is possible to place the nose bridge directly or indirectly on the frame element.

These bridges are preferably made integrally with the bridge, for example by 3D printing, but can alternatively be mounted on the bridge by welding or gluing.

Using a nose bridge equipped with a nose bridge, it is possible to adjust the distance between the eyes and the shape of the nose.

As mentioned earlier, the distance between the eyes is changed by a longer or shorter bridge of the nose.

As mentioned, the shape and size of the nose has a major impact on how the glasses rest on the face with respect to the eyes, and how the bridge of the nose passes through the nose. When using a nose bridge, it will be possible to take into account the huge differences in nose appearance in a simpler way. Therefore, it is advantageous to mount the nose bridges on replaceable nose bridges so that they can be replaced together with the nose bridges. The interchangeable nose bridge allows making variants of spectacles that rest on the bridge or sides of the nose to accommodate tall, thin bridges, wide bridges and very flat bridges, while at the same time ensuring the correct placement of the spectacle lenses with respect to the pupil.

Therefore, a nose bridge with a bridge will make it even more likely for the optician to provide a high level of service with a small inventory.

In another aspect, the present invention also relates to spectacles, wherein the spectacles are further characterized in that the nose bridge includes a nose bridge support arm, wherein the nose bridge support arm is preferably formed by a metal wire having a fold at its free end part, wherein the elastically flexible nose bridge spacer is held by clamping. The fold can be shaped like a loop or a fork.

In order to obtain the best possible adjustment of bridges for different nose shapes, it is preferred that the bridges comprise bridge arms on which the bridge spacers are mounted. By making the nose bridge arms out of metal wires, the nose bridge is adjustable, and the optician can make adjustments in a simple way by bending the nose bridge arms, so that the nose bridge spacers are used to ensure that glasses with lenses are relevant for use. The user's pupil rests on the user's nose in such a way that the user's pupil is correctly positioned in the correct position.

In another aspect, the invention also relates to eyeglasses, wherein the eyeglasses are further characterized in that the nose bridge includes a curved intermediate portion and a flat end portion at the two coupling elements.

A nose bridge with a curved middle portion makes it possible to allow the glasses to conform to tall, thin noses, while at the same time being able to position the glasses close to the user's pupils. By having the flat end of the nose bridge, a simpler design of the coupling element of the frame element will be achieved.

In another aspect, the present invention also relates to glasses, wherein the glasses are further characterized in that the coupling element of each frame element includes at least one second recess connected to the first recess, the second recess extending toward the outside of the frame element and is configured to receive the end of the nose bridge when it is installed in the frame member, so that the nose bridge remains torsionally stable in the slot when the lens is installed in the frame member.

By creating a second recess in the frame element, it is possible that not only the adapter element is located in the recess, but also a part of the nose bridge, preferably the above-mentioned planar end, is also accommodated in the second recess. With this configuration, a particularly torsionally stable retention of the nose bridge is obtained after the lens has been mounted.

In another aspect, the invention also relates to spectacles wherein the spectacles are further characterized by a recess in the frame member and the size of the portion of the bridge for receiving in the recess so that the bridge is installed in the slot. A press fit is established in the middle.

When the nose bridge is installed in the recess of the frame element, by applying a press fit, positioning the slot is possible so that no lens is required to hold the coupling element of the nose bridge in the coupling element of the frame. The aforementioned recess is made in the position of the first recess connected to the circumferential groove, so that it is also possible to create a press fit between the nose bridge and the frame element. This helps to keep the nose bridge in the frame element during installation/removal without having to install the lens in the frame element.

In another aspect, the invention also relates to eyeglasses, wherein the eyeglasses are further characterized in that the frame elements are made of a material with elastic properties.

This makes it possible to insert a lens into a frame element with an unbroken circumference. The elastic and flexible nature of the frame member will facilitate manual pressing of the lens into the frame member so that the lens engages the slot in the frame member.

In the description of the drawings, identical or similar elements will have the same reference numerals in different drawings. All details related to each drawing/embodiment will not be fully explained.

The drawings show specific embodiments. It is possible to have further embodiments, just as it would be possible to combine details from the shown embodiment with other details of other embodiments.

FIG. 1 illustrates two images A and B illustrating eyeglasses 1 comprising two annular frame elements 2 connected to a nose bridge 3 . Each annular frame element 2 has, on the side opposite the nose bridge, an extension 4 (not shown here) containing a coupling element for coupling with each of its eyeglass side pieces (not shown here). This coupling preferably takes place via a hinged joint, making it possible to pivot the two spectacle side pieces with respect to the front bridge formed by the two frame elements 2 and the nose bridge 3 .

Each frame element 2 contains a lens 5 . The figures illustrate the centerline 6 for each of the two lenses. In normal use, the centerline will have a horizontal orientation. Again, the vertical line 7 indicates the point for the pupil, so that the distance 8 between the two vertical lines 7 indicates the interpupillary distance.

Image B illustrates a view similar to image A. However, the nose bridge 3 here is made shorter, so that the interpupillary distance 8 is shorter than that shown in image A.

By changing the length of the nose bridge, it is therefore possible to adjust the interpupillary distance of the glasses.

The vertical line 9 indicates the line of symmetry for the glasses 1 .

Figure 2 shows four different embodiments of the nose bridge 3 in images A-D. In each image, the nose bridge is shown from the front, from the side, and from above.

The nose bridge 3 comprises a curved middle portion 10 having flat ends 11 on each side of the curved middle portion 10 . The planar end 11 is connected to a first coupling element 12 designed and configured as a corresponding second coupling element provided on each of the two frame elements 2 . This will be explained in more detail below.

It can be seen that the first coupling element 12 is banana-shaped. The coupling elements are designed to suit the corresponding shape of the frame elements to which the nose bridge 3 is to be fastened. Therefore, the coupling element may have a different shape than that shown in image A.

The coupling element 12 has a slot 14 on its side facing the outer side 13 , that is to say facing the lens 5 . This slot is used to receive the side edge area of the lens. This will be explained in more detail below.

In this regard, the term facing outwards means a direction away from the line of symmetry 9 of the eyeglasses.

The embodiments shown in images B, C and D differ from that shown in image A in that the shape and size of the middle portion 10 of the nose bridge is different.

Therefore, it is possible to give the nose bridges different lengths, but it is also possible to give the nose bridges different shapes/curvatures. Therefore, the nose bridge is not only used to adapt the glasses to different interpupillary distances, but also serves as a design element on the glasses.

FIG. 2 illustrates an embodiment in which the first coupling element 12 is placed on this flat end 11 on the side facing away from the outwardly directed curvature of the intermediate portion 10 .

The nose bridge can be mounted on the front of the frame element 2 of the spectacles, ie facing the side facing away from the user, or it can be mounted on the back of the frame element 2, ie the side facing the user. Therefore, the nose bridge may provide more or less visibility to the observer, and thus produce different design effects.

FIG. 3 illustrates another embodiment different from the embodiment shown in FIG. 2 , in which the first coupling element 12 is placed on the flat end 11 on the side facing the outer guide curvature of the face facing the middle part 10 . Here again, leading outwards means facing away from the user.

In this embodiment, the first coupling element 12 is shown with a shorter extension and a different shape/curvature, the first coupling element is intended to cooperate with frame elements having the same characteristics as shown in FIG. 1 . Illustrated shapes are different shapes.

FIG. 4 illustrates a nose bridge 3 corresponding to the nose bridge shown in FIG. 3 . However, the embodiment shown in Figure 4 differs in that each end is fitted with a nose bridge 15. The bridge 15 has linear bridge arms and is attached to the bridge 3 at point 16 . The linear nose bridge 15 is folded at the outer end of the nose bridge to form a loop 17 . This ring is intended to hold the nose bridge spacer sandwiched in the ring. The bridge pad is configured to abut the bridge of the user's nose.

Alternatively, the nose bridge 15 may be mounted on a frame member. However, they are advantageously located on the nose bridge 3 so that the combined unit consisting of the nose bridge 3 and the nose bridge 15 can not only adjust the interpupillary distance by selecting the length of the middle part 10 of the nose bridge, but also with respect to the user's Anatomy and nose shape to adjust the position of the glasses. This is done by applying a different nose bridge or by adjusting the wire material for abutment with the user's nose. Thus, an adjustment of the positioning of the spectacle lens with respect to the pupil of the user can be established.

FIG. 5A shows a cross-sectional view of a different embodiment of the coupling between the lens 5 and the frame element 2 using the nose bridge 3 .

Image A-A in FIG. 5A corresponds to the section according to arrow A-A in FIG. 5B. Thus, it can be seen that this section passes through where the nose bridge 3 is installed. Section B-B shows the position on the frame element 2, where only the first coupling element 12 on the nose bridge is visible.

In FIG. 5B , the images C-C show that the frame element 2 has a first coupling element in the form of a first recess 18 . The recess 18 is placed in connection with a circumferential slot 19 provided in the inner side of the frame element (see also Fig. 5A).

The circumferential slot 19 serves to receive the lens 5 by receiving the edge region therein.

When the nose bridge 3 is installed with the first coupling element 12 in the recess 18, the recess constitutes a corresponding second coupling element provided on the frame element 2, and the slot 14 provided in the first coupling element 12 will be Extends in the continuation of the circumferential slot 19 .

The first coupling element 2 of the nose bridge received in the recess 18 can thus be considered as the adapter part. In the area where the recess 18 is provided, the adapter part means the part that adjusts between the frame part and the lens.

When the lens 5 is mounted in the frame element 2 , the nose bridge 3 will thus be held to the frame element 2 .

FIG. 5B also shows the second recess 20 . This second recess 20 is connected to the first recess 18 and thus the recess extends towards the outside of the frame element 2 . This second recess 20 serves to receive the flat end 11 of the nose bridge, as can be seen most clearly in the image on the left side in Figure 5B. An even greater certainty of torsional stability in this connection is achieved when the flat end 11 is mounted in the second recess 20 .

The nose bridge will thus have an adapter portion located in the recess 18 , and the flat end 11 will be received in the recess 20 , which is oriented generally perpendicular to the extension of the recess 20 .

In FIG. 5B, the frame element 2 is shown in an approximately circular embodiment. However, the frame element can also be designed to have other shapes, such as those shown in the previous figures.

Figure 5A shows that the circumferential slot 19 in the frame element can have different shapes. The circumferential slot 19 is not shown, but in images B-B in FIG. 5A , the cross-sectional shape of the first coupling element 12 is illustrated, wherein the slot 14 has been formed with a shape corresponding to the shape of the circumferential slot 19 . The slots 19 (and 14) can thus be provided as depressions (slots) or protrusions (tongues) suitable for coupling.

In B-B of Fig. 5A, another embodiment is seen in which elastic elements 21 or 22, respectively, have been provided, which have a circular or rectangular cross-section.

The elastic elements 21, 22 will preferably be made of rubber. The use of elastic elements 21 , 22 between the bottom 23 of the recess 18 and the first coupling element 12 makes it possible to take into account tolerance uncertainties.

The frame element 2 is made of plastic or another elastic material, allowing the lens to be pressed into the circumferential slot 19 of the frame element 2 using only manual force.

FIG. 6 shows a schematic view from above the user 24 wearing the glasses 1 . A user 24 is shown with a nose 25 of different shapes.

At the top of Figure 6, a rather elongated nose is shown. The middle image shows a tall and wide nose 25, and the bottom image shows a nose 25 with a flat bridge.

For illustrative reasons, the bridge of the nose is shown to coincide with the middle portion 10 of the bridge of the nose. However, in practice there will be some distance so that the bridge of the nose does not rest directly on the bridge of the nose.

On the other hand, the nose bridge 15 will rest on the user's nose. The nose bridge mounted on the nose bridge 3 is fitted with a nose bridge spacer 26 which rests on the user's nose.

Therefore, taking into account the different shapes of the user's nose, FIG. 6 illustrates how the alternative nose bridge 3 can be assembled with different types of nose bridges 15 .

As mentioned above, the combined product of the bridge and bridge will be able to adjust in the size form of the nose according to the user's anatomy so that the glasses are positioned correctly with respect to the user's eyes.

Figure 7 shows the two frame elements 2 and the nose bridge 3 in a separated state. As can be seen in image A, the recess 20 is located on the front of the glasses and is connected to the recess 18, and the first coupling element will be received in this recess. It can be seen that when the glasses are used, the observer will be able to see the flat end 11 received in the second recess 20 . This is illustrated in image C.

Image B shows the nose bridge 3 connected to the frame element 2 on the left.

Image C shows the nose bridge 3 connected to the two frame elements 2, with the lens 5 inserted, so that the fixation of the nose bridge is established.

FIG. 8 shows an image corresponding to FIG. 7 . The difference here is that the second recess 20 resides on the back side of the frame element 2, ie the side facing the user. This means that after installation, the flat end 11 of the nose bridge 3 will not be visible to the observer. This is clear in image C, where the nose bridge is mounted in the two frame elements and the lens 5 is inserted.

In FIG. 8 , the glasses are viewed from the front, and therefore the first recess 18 is not visible in FIG. 8 .

In FIG. 9, image A shows the unassembled glasses viewed from the back, ie, the side facing the user. Image B shows an image corresponding to image A viewed from the front without the glasses assembled.

In these spectacles, the frame element 2 is fitted with mounting openings 27 in which the bridge of the nose can be fixed, for example by gluing. As an alternative to the embodiment shown, it is also possible to mount the nose bridge on the nose bridge 3 as described above.

FIG. 9 illustrates that on the outside of the frame element 2 , a first recess 18 and a second recess 20 corresponding to the recesses 18 and 20 have been formed for connecting the nose bridge 3 .

Figure 9 shows connecting elements 28 for each frame element 2 and intended for the attachment of eyeglass side pieces.

The connecting element 28 has a first coupling element 29 corresponding to the first coupling element 12 on the nose bridge. Furthermore, the flat end 30 has been provided on a part of the connecting element 28 that connects the first coupling element 29 to the remaining angled folds of the connecting element 28 . The connecting element 28 will therefore be able to be placed in the recesses 18 , 20 on the outside of the spectacles in a similar manner to the installation of the nose bridge 3 . Since the first coupling element 29 also has a slot (not shown) connecting the circumferential slot on the inside of the frame element 2, after the lens has been pressed into the frame element 2, the lens will hold not only the nose bridge 3 but also the connecting element 28.

FIG. 10 illustrates another embodiment in which the various steps for installing the nose bridge 3 in the two frame elements 2 are illustrated. In this embodiment, the frame element 2 is shown with mounting openings 27 for the nose bridge.

Figure 11 shows another embodiment of eyeglasses in which the nose bridge 3 is mounted from the back of the frame element 2 so that the flat end 11 is not visible to the observer. Figure 11 shows views from the front and from above, respectively.

FIG. 12 shows an image corresponding to FIG. 11 . Here, it can be seen that the nose bridge 3 is mounted in front of the frame element 2 . Thereby, the observer can see the flat end 11 of the nose bridge 3 .

Figures 11 and 12 show that the nose bridge can be positioned with its middle portion 10 substantially flush with the front face of the frame element 2, as shown in Figure 11, or the middle portion 10 can be positioned in a plane lying in the front face of the frame member 2 , as shown in Figure 12.

By designing the curvature of the nose bridge 3 it is therefore possible to take into account different anatomical structures of the nose. The middle portion 10 of the nose bridge 3 can be given a larger or smaller curvature, which is suitable for larger or smaller noses.

FIG. 13 illustrates the details of the frame element 2 . The frame element includes a first concave portion 18 and a second concave portion 20 located on the back of the frame element 2 . In this embodiment, both recesses 18, 20 have been provided with connecting elements 28 for the nose bridge and for attaching the eyeglass side pieces.

The sectional view A-A is a cross-section through the frame element 2 and shows the slot 19 according to the arrow A-A. Sectional view B-B is a cross-section through the frame element according to arrows B-B and illustrates the cross-section of the frame element in which the nose bridge 3 is installed. In addition to the slot 19, it can also be seen that the frame element is fitted with a second recess 20 which allows to receive the flat end 11 of the nose bridge (not shown in Figure 13).

The position of the recesses 18 and 20 , both in the position for receiving the nose bridge and in the position for receiving the connecting element 28 , is illustrated according to the cross-section C-C of the arrows C-C.

The present invention is not limited to the embodiments shown above, which are illustrative of specific embodiments of the invention.
