Patent Description:
Eyeglass systems are known, that comprise at least one lens and at least one frame element, where the at least one frame element comprises a front side, a back side, an outer side with an external circumference and an inner side with an internal circumference, where the at least one frame element further comprises a connection element which is intended to connect with an eyeglass lens.

Eyeglass systems with an eyeglass lens and a frame element are used, among other things, as sunglasses, where several interchangeable eyeglass lenses follow a frame and thus can be exchanged according to the sun situation.

An eyeglass system is also known from <CIT>, where a frame element which preferably is made of metal or plastic is heated, after which the eyeglass lens is placed in the frame element and is connected when cooled.

From <CIT> an eyeglass system is also known, where eyeglass lenses are placed in a casing of the frame element, after which the edge of the frame element is curved/bent down towards the eyeglass lenses - preferably without use of heat - and thus are connected.

From <CIT> yet another eyeglass system is known, comprising a frame element and also two eyeglass lenses, where the eyeglass lenses can be put in the frame element and be exchange with just manual force and without the use of heat.

From <CIT> an eyeglass system is known, of the type named in the introduction. Here, there is no description of any form of adapter element which can establish a stable mounting of the hinge element on the frame element.

From <CIT> an eyeglass system is known, of the type named in the introduction. Here, there is no description of any form of adapter element which can establish a stable mounting of the hinge element on the frame element by having a first recess and a second recess extending to the outer side of the frame in such way that a nose bridge or a hinge element is rotationally secured to the frame element.

The fundamental purpose of the invention is to make it convenient. , flexible and uncomplicated to assemble, separate, replace and service a self-locking eyeglass system without the use of tools, where the eyeglass system in addition to the frame element and the eyeglass lenses forming locking elements, additionally also comprises hinge elements, and where such hinge elements can be stably mounted on the frame element.

In other words, it is a purpose to show an eyeglass system where only the manual human force is necessary to place or remove an eyeglass lens, and where it is the eyeglass lenses which as locking elements are manually pressed into the frame element, which constitutes the most important locking function in the self-locking eyeglass system. In the eyeglass system, the hinge elements are locked fixed by the eyeglass lens. Here, additional elements as for example temple bars, be locked onto the frame element.

As used in the present application the terms "first recess" and "second recess" refers to recesses for receiving the adapter element used in connection with the hinge element, the nose bridge and a secondary eyeglass element in form of a rod connecting two frame elements.

Moreover, in the present application the term "locking element" is understood to be an "eyeglass lens".

According to one aspect of the invention, the above purposes are achieved with a self-locking eyeglass system as has been described in the introduction, and as described in the preamble of claim <NUM>, where each hinge element comprises an adapter element, which is complementary to at least one first hinge recess in the at least one frame element, where the at least one first hinge recess is provided from the inner side in the direction towards the outer side and that the hinge elements are mounted in the at least one frame element's first hinge recess and that the at least one frame element additionally comprises at least one second recess extending on at least one of the frame element's front side and back side, wherein the second recess extends between the frame element's at least one first hinge recess and the frame element's outer side, wherein the second recess is intended to accommodate the hinge element.

This makes it possible to receive the at least one hinge element. It rotationally secures the hinge elements and thus the temple bars, as the connection elements prevent that the hinge elements and thus also the temple bars from moving along the frame element's inner side or outer side, and interacting with the first hinge recess in the frame element, the temple bars also cannot move in direction transversal to the frame element's front side and back side.

For eyeglasses with one frame element and only one eyeglass lens, for example sport glasses or sunglasses, it is made possible to collect and lock in place the hinge elements onto the frame element, also called the casing, where the locking takes place when the eyeglass lens is put in place, the lens is the locking element in the frame element, where the hinge elements are not able to fall out from the at least one frame element's first hinge recess. The adapter elements ensure that the hinge elements sit stably on the frame.

Self-locking thus means that the eyeglass system's elements together can be locked and hold the relatively few elements of the eyeglasses, and thus without use of screws, nails, rivets, strings or other loose parts that are generally known as holding implements.

With an unbroken frame element is meant that the frame element is in one piece and does not have joints that can be opened or closed, to set the eyeglass lens in place in the frame element.

The connection element will, in a preferred embodiment, be placed along the whole frame element's inner side, but can in an alternative embodiment be placed along a part of the inner side of the frame element, and in yet another alternative embodiment, there can be connection elements arranged in several places around the inner side of the frame element, separate from each other by a space without connection elements.

The frame element can be made of metal or plastic. For example, metal in the form of steel or titanium or a plastic material of a type that is commonly used at the manufacture of eyeglasses.

The present invention concerns in an additional aspect also a self-locking eyeglass system, where the eyeglass system comprises an additional eyeglass lens.

That is to say that the eyeglass system comprises at least two eyeglass lenses.

For an eyeglass with one frame element and two eyeglass lenses, it is here made possible to collect and lock the hinge elements to the frame element, also called the casing, where the locking takes place by putting the eyeglass lenses into the frame element, where the hinge elements are not able to fall out of the first hinge recess in the at least one frame element.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system, where the eyeglass system comprises an additional frame element and a nose bridge. The nose bridge connects the frame elements, and the nose bridge comprises adapter elements, which are complementary to at least one first nose bridge recess in each of the frame elements.

Each adapter element, whether it is for the hinge element or the nose bridge has a connection element, which coincides with the frame element's connection element, when the adapter element of the nose bridge is mounted in a frame element's first nose bridge recess. The nose bridge's adapter elements are secured to each its own frame element by the eyeglass lens.

For eyeglasses with two frame elements and two eyeglass lenses, it is here made possible to connect, collect and lock in place both the nose bridge and the two hinge elements to the two frame elements, where the locking takes place when the eyeglass lenses are put in place.

The present invention concerns in an additional aspect, a self-locking eyeglass system, where frame element, hinge element and a nose bridge have connection elements, which are suitable for connection to the eyeglass lenses.

This makes it possible, if frame element, hinge element and the nose bridge have connection elements in the form of depressions (groove or recess), to receive the eyeglass lenses therein. The depression may thus be provided in an embodiment without a nose bridge.

In a preferred embodiment, a frame element has a connection element with two side surfaces, where one side surface thus can be everted out over the eyeglass lens, after which the connection element has a side surface on each side of the eyeglass lens, to hold in place the eyeglass lens. A connection element which comprises a depression with a bottom surface and two side surfaces, thus makes it possible to receive a part of the eyeglass lens's side surface area, whereby the eyeglass lens is held fast.

With a connection element, which consists of a depression and comprises a bottom surface and two side surfaces, is meant a groove which essentially has a U-shape or a V-shape, where the bottom surface can have an arbitrary shape, and where the transition to the side surfaces can be either a sharp separation or a curve shaped separation, but where there shall be side surfaces to prevent that the eyeglass lens falls out of the frame element.

In another embodiment, the frame element, the hinge element and also the nose bridge have connection elements in the form of a protrusion (tongue) to receive the eyeglass lens. If this embodiment is used, it requires that the eyeglass lens has a depression which is complementary to the protrusion, as a connection otherwise will not be a possibility.

The present invention concerns, in a further aspect, also a self-locking eyeglass system, where each frame element further comprises at least one further second nose bridge recess extending on at least one of the frame element's front side and back side, where the further second nose bridge recess extends between the frame element's at least one first nose bridge recess and the frame elements outer side, where the further second nose bridge recess is intended to accommodate the nose bridge.

This makes it possible to receive the nose bridge in such way that the connection element rotationally secures also the nose bridge.

It is possible to receive eyeglass elements such as the at least one hinge element and/or the nose bridge.

One thing does not exclude the other, so both hinge elements and the nose bridge can thus have connection elements in the frame elements, which prevent rotation.

The present invention concerns in an additional aspect also a self-locking eyeglass system, where each frame element additionally comprises at least one further second rod recess extending on at least one of the frame element's front side and back side, where the further second rod recess extends between the frame element's at least one first rod recess and the frame element's outer side, where the further second rod recess is intended to accommodate a secondary eyeglass element.

This makes it possible to receive secondary eyeglass elements, such as additional stiffening elements besides the nose bridge, or to receive elements without any actual functional properties, but elements of more of an architectural/design character.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system, where at least one of the adapter elements on the hinge elements and the adapter elements on the nose bridge, provided it is comprised, comprises a longitudinal connection element, which when the adapter element is mounted in the frame element, is essentially lying in the same plane as the edge of an inserted locking element, and where the connection element is precisely intended to interact with the eyeglass lens. The longitudinal connection element may thus be provided in an embodiment without a nose bridge.

Thereby, the adapter elements will also function as an adapter element to retention of the eyeglass lens. In a preferred embodiment the connection elements are alike, regardless of whether it is a connection element in a frame element, a hinge element or a nose bridge, whereby the connection elements in the circumference of the frame element are substantially alike.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system where at least one of the adapter elements on the hinge elements and the adapter elements on the nose bridge, provided it is comprised, comprise a different material on the side of the adapter elements, which is intended to face the eyeglass lens.

This makes it possible to coat the adapter elements' connection elements or to put a packing element between the connection elements and the eyeglass glass, thus to ensure that there is no direct contact between the eyeglass glass and the materiel of which the connection elements are made, as for example a metal in the form of steel or titanium. Alternatively, the connection elements can be a plastic material of a type that is commonly used when manufacturing eyeglasses.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system, where the adapter elements on the hinge elements and the adapter elements on the nose bridge, provided it is comprised, are adapted to the first recesses in the frame elements, such that both the adapter elements on the hinge elements and the adapter elements on the nose bridge have opposite pulling and pushing forces, relatively to the frame elements.

This makes it possible that the nose bridge and the hinge elements can be moved in parallel in the direction away from the frame elements and thus in the direction of the outer side of the frame elements, after which they are locked in place in the frame elements by the eyeglass lenses, when the eyeglass lenses are inserted into the frame elements. In a preferred embodiment, the parallel move can be done along a line, where the forces are directly opposed, but in alternative embodiments the adapter elements on the nose bridge and the adapter elements on the hinge elements be moved only in the direction of the frame elements' outer side to the for this purpose desired and for this purpose constructed place on the frame elements.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system where the eyeglass system additionally comprises at least one clasp with a respective clasp arm and clasp cushion, where the clasp is placed on one of the at least one frame element and the nose bridge, respectively.

Thus, it is possible to manufacture the clasp or at least the clasp arm at the same time as the manufacture of the bridge, alternatively the clasps shall be mounted later, on the bridge or directly on a frame element.

The present invention concerns, in an additional aspect, also a self-locking eyeglass system, where the frame elements are manufactured of material with elastic properties.

Where, by the frame element having elastic properties, is meant that the frame element is capable of yielding so much that the eyeglass lens via a snap function can be pressed in engagement with the frame element's connection element, where the eyeglass lens can be held fast and constitute the locking element for the adapter elements.

Thus, it is made possible to insert the eyeglass lens into a frame element which is unbroken in its circumference, in that the elastic and flexible properties causes that the eyeglass lens can manually be pressed into a frame element, where the eyeglass lens engages with the connection element of a frame element and at the same time the adapter elements are locked in their position in the recesses in the frame element.

The invention will in the following be explained in more detail by description of nonlimiting embodiments, with reference to the figures, where:.

In the description of the figures, identical or corresponding elements will be given the same reference number in the different figures. Thus, an explanation of all details in each figure/embodiment will not be given.
