Description

Glasses frame with resilient element

The present invention relates to a spectacle frame with a resilient hinge.

Spectacle frames are known from the prior art, with a frame holding one or more lenses in order to improve a user's vision through the one or more lenses. In order to attach glasses to the wearer's head, a pair of brackets is usually arranged on the frame, so that in a wearing position the glasses essentially rest against the nose and the two ears and are held there. The brackets are usually each connected to the socket by means of a spring hinge, which usually includes a spiral spring.

The spring hinges usually consist of a large number of precisely manufactured individual parts, which must be precisely mounted on the frame and/or the temples. In addition, a special tool for assembling the spiral spring and/or the large number of individual parts associated with the spiral spring is often necessary for assembly.

The object of the present invention is therefore to provide a simpler and in particular easier to assemble resilient coupling for coupling a bracket to a frame of a spectacle frame.

The above-described task is solved by the subject matter of the independent claims; preferred embodiments are the subject matter of the dependent claims. One aspect of the invention relates to a spectacle frame comprising:

- a frame for one or more lenses;

- at least one bracket which is deflectably coupled to the socket;

- wherein at least one of the socket and the at least one bracket has a receptacle;

- a resilient element which is arranged at least in sections on the receptacle,

-- wherein the resilient element provides a restoring force when the bracket is deflected relative to the socket and wherein the resilient element can in particular be formed from an injection-molded material or from a 3D printed material.

The resilient element can in particular be arranged in sections on and at least partially in the receptacle. Furthermore, the resilient element can protrude from the receptacle in particular in certain areas. For example, the resilient element can protrude from the receptacle at least in some areas towards the other of the socket and the at least one bracket. In particular, the resilient element can protrude or protrude from the receptacle at least in some areas, projecting from the socket and the at least one bracket.

By the present spectacle frame providing a receptacle on which the resilient element is arranged at least in sections, a simplified assembly of the resilient element on the spectacle frame can advantageously be ensured. By providing the receptacle integrally by the frame and/or by the at least one bracket, the number of parts of the spectacle frame can be further advantageously reduced, in particular for the resilient coupling of the at least one bracket to the frame. This further advantageously improves the assembly for the resilient coupling between the socket and the at least one bracket. The restoring force provided by the resilient element particularly counteracts the deflection of the bracket and can therefore advantageously counteract or prevent damage to the socket, the bracket and/or the coupling, such as a swivel joint.

The resilient element can in particular be designed to provide a restoring force only when the bracket is deflected beyond a normally open position of the bracket. The normally open position of the bracket is, in particular, a position of the bracket relative to the socket, with the bracket being deflected approximately 90° relative to the socket. In other words, the normally open position of the bracket is, in particular, a position of use of the bracket into which the bracket is folded or deflected in order to then put on glasses, which include the at least one bracket and the frame.

As a result, the resilient element advantageously makes it possible to counteract a deflection or unfolding of the bracket beyond the normally open position, i.e. beyond the position of use, and to cushion and in particular to inhibit a deflection or unfolding beyond the normally open position and, if necessary, to put the bracket back in which returns the normally open position. In particular, the bracket can be returned to the normally open position, i.e. the position of use, when the bracket has been deflected beyond the normally open position.

In exemplary embodiments, both one of the socket and the at least one bracket can have the receptacle, and the other of the socket and the at least one bracket can have a receptacle. In other words, in exemplary embodiments, both the frame and the at least one bracket can have a receptacle for arranging the resilient element thereon.

In further exemplary embodiments, the socket can in particular have a receptacle for each bracket that is pivotally coupled to the socket Arrangement of the resilient element on or in it.

The reception of the at least one of the socket and the at least one bracket and/or the reception of the other of the socket and the at least one bracket can, for example, be a recess in order to accommodate the resilient element at least in sections, or a pin in order to do so to push on the resilient element at least in sections, in particular to press it on or shrink it on, and to be a clip or a groove in order to arrange the resilient element thereon. The receptacle or receptacles can, in particular, configure a releasable attachment for the resilient element with the resilient element. This can advantageously facilitate maintenance and any necessary repair or replacement of the resilient element.

The various designs for arranging the resilient element by means of one or more receptacles advantageously enable the resilient element to be arranged securely on the at least one bracket and/or on the socket, and to apply a restoring force in a safe and targeted manner.

In exemplary embodiments, the resilient element may be a unitary element that is disposed both to receive the at least one of the socket and the at least one bracket and is configured to contact the other of the socket and the at least one bracket to to provide a restoring force.

For example, the resilient element can be a one-piece element, which is arranged both on the receptacle of the at least one of the socket and the at least one bracket, and can also be positioned on and in particular in the receptacle in such a way that the resilient element is the other of the socket and the at least one bracket, in particular when the bracket is deflected beyond the normally open position of the bracket, in order to provide a restoring force. In further exemplary embodiments, the receptacle can be formed integrally on or with the at least one of the sockets and the at least one bracket. If the other of the socket and the at least one bracket also has a receptacle, this receptacle can optionally also be formed integrally on or with the other of the socket and the at least one bracket. In exemplary embodiments, a first recess can be designed as a receptacle in the at least one of the sockets and the at least one bracket. Optionally, a second recess can also be designed as a receptacle in the other of the socket and the at least one bracket.

Due to the integral design of the receptacle(s) on or with the socket and the at least one bracket, and in particular due to the design of the receptacle(s) as recess(s), the resilient element can advantageously be securely attached to the socket and/or the at least one Bracket can be arranged. Furthermore, a resilient coupling between a frame and a temple of a spectacle frame can advantageously be provided by means of a small number of parts, in particular ensuring comparatively simple assembly.

In further exemplary embodiments, the receptacle can be provided by one of the socket and the at least one bracket or can be designed in such a way that the receptacle has a stop, which the other of the socket and the at least one bracket provides for the resilient element, flees.

In particular, the resilient element can be arranged on or in the receptacle of one of the socket and the at least one bracket, such that the resilient element has a stop, which the other of the socket and the at least one bracket for the resilient element, in particular for applying the resilient force, provides, is aligned.

This can advantageously reduce the number of parts for configuring the resilient Coupling of the at least one bracket with the frame can be reduced, which in turn advantageously simplifies the production and assembly of the glasses frame.

The resilient element can be formed from an injection-molded material, in particular an injection-molded plastic, or from a 3D printed material, in particular a 3D printed plastic.

As a result, the resilient element can advantageously be produced in a simple, cost-effective manner and with repeatable accuracy or, in relation to a 3D printed material, can also be produced in an application-specific manner.

The resilient element can in particular have or consist of a plastic, such as an elastomer, a thermoplastic elastomer, a thermoplastic, a resin, or another plastic, or a mixture or mixture thereof. Furthermore, the resilient element can in particular have or consist of a metal, such as an iron-containing metal or a non-ferrous metal. Even further, the resilient element can in particular have or consist of an organic material, such as wood, cork, mushrooms. Even further, the resilient element can in particular have or consist of a composite material, for example a fiber-reinforced plastic, in particular a plastic reinforced with hemp fiber, a plastic reinforced with flax fiber, a plastic reinforced with glass fiber, a plastic reinforced with carbon fiber, or a composite material from a combination two or more of the other aforementioned materials and materials.

In exemplary embodiments, the resilient element can be filled at least partially with a fluid, such as a liquid or a gel.

In the following, various terms are used repeatedly, the understanding of which is intended to be made easier by the following definitions. Frame: The frame as used herein describes a spectacle frame or in other words a spectacle lens frame. It is therefore designed so that one or more spectacle lenses can be arranged on it or can be accommodated by it. For this purpose, the frame can have one or more corresponding cutouts or openings to which one or more lenses can be mounted. The lenses can include a transparent or semi-transparent material that is common for glasses. The frame as used here represents a frame without lenses, but which is suitable for holding one or more lenses. The frame can therefore in particular include an edge for the one or more spectacle lenses into which the one or more spectacle lenses can be inserted. Alternatively, the frame can be a partially rimless or rimless frame, so that the frame can consist of several parts, which are first connected using the lenses.

Spectacle frame: Based on the above definition of the frame, the spectacle frame as used here includes in particular a frame and one or more temples, but not necessarily the one or more lenses.

Bracket: The bracket as used here represents a substantially elongated element which is arranged on the socket, in particular is coupled to the socket in a pivotable or foldable manner. The brackets can in particular assume a folded position and an unfolded, normally open position, which can essentially correspond to a user's carrying position. In the folded position, the bracket is arranged with its main extension direction essentially parallel to the socket or laterally adjacent to the socket. The main extension direction of the bracket can in particular essentially correspond to an imaginary line between a connection of the bracket to the socket and a support point that the bracket provides for an ear. Despite its essentially elongated extension, the bracket can have a curved contour and/or one that is adapted to the shape of a user's face or head.

In exemplary embodiments, the at least one bracket can be coupled to the socket, in particular by means of a joint, for example by means of a swivel joint, a hinge or a fold, so that the at least one bracket can preferably be deflected or pivoted about the joint.

If a direction or an angle is represented here with the addition “essentially” or “approximately” or “approximately,” this addition generally means, in particular, a deviation from the relevant direction or angle in the range of 0° to 5° meant or understood.

If a spatial measure, a spatial ratio or another relationship is reproduced with the addition “essentially” or “approximately”, this addition is intended to mean in particular a deviation from the relevant measure or the relevant ratio in the range of 0% to 10%. meant or understood.

In preferred embodiments of the spectacle frame, the resilient element can:

- be a winding-free element and/or

- be a solid body; and or

- be a non-spring element, in particular neither a spiral spring nor a leaf spring; and or

- be a non-metallic element; and or

- have or consist of a plastic.

Since the resilient element is a coil-free element and/or a solid body, i.e. in particular not a wound wire-shaped element, the resilient element can be produced in a simple manner by means of injection molding or by means of 3D printing. This means that the resilient element can also be produced with repeatability and in a cost-effective manner. Since the resilient element is a non-spring element, i.e. in particular neither a spiral spring nor a leaf spring, the resilient element can advantageously be assembled in a simple manner, since usual spring elements are usually assembled with a large number of individual parts and may require a special tool for assembly and/or or for dismantling, i.e. for replacement or repair.

Because the resilient element is a non-metallic element and in particular has or consists of a plastic, the resilient element can advantageously be produced in a cost-effective manner and in particular in a recyclable manner. For example, a supposedly defective resilient element can be remelted and manufactured into a new resilient element. The production or production is advantageously carried out using injection molding or 3D printing. Further advantageously, the preferred non-metallic design of the resilient element results in resistance to corrosion. In particular, the resilient element can be resistant to salt water.

In preferred embodiments of the spectacle frame, the receptacle can be a first recess, with the resilient element being arranged at least in sections in the first recess, and preferably extending out of the recess, in particular extending towards the other of the frame and the temple.

As a result, the resilient element can advantageously be arranged in a form-fitting manner on the receptacle, and can also advantageously be mounted and dismantled in a simple manner, for example for changing or replacing the resilient element.

Further advantageously, the resilient element can be advantageously aligned by means of the first recess, towards the other of the socket and the at least one bracket, whereby the restoring force or effect can be advantageously adjusted.

In preferred embodiments of the spectacle frame, the resilient element can extend at least in sections in the recess and have a constant outer diameter along its extension.

Due to the essentially constant outer diameter of the resilient element, tilting or jamming of the resilient element in the recess can advantageously be prevented, as can occur in particular with spiral springs which have a discontinuous outer diameter due to the turns. As a result, a predetermined restoring force or effect can be advantageously ensured.

The continuous outer diameter can in particular be characterized by an outer circumferential side which has a continuous cross-section.

In exemplary embodiments, the resilient element can form a press fit, a transition fit, or a clearance fit with the recess at least in sections.

The recess can have a depth, in particular parallel to the longitudinal extent of the bracket, of approximately 3 mm to approximately 6 cm, preferably of approximately 5 mm to approximately 4 cm. The depth can be selected depending on the fit used. While a press fit ensures a secure fixation of the resilient element in the recess, even with a comparatively small depth of the recess, a transition fit and a clearance fit enable particularly easy assembly and disassembly, and are particularly suitable for a comparatively large depth of the recess. The comparatively small depth of the recess can, for example, be in a range from approximately 3 mm to approximately 4 cm, preferably in a range from approximately 5 mm to approximately 2 cm, but without being limited to this. The comparative A large depth of the recess can, for example, be in a range from about 6 mm to about 6 cm, preferably in a range from about 8 mm to about 4 cm, but without being limited to this. The depth of the recess can generally be in a range of about 2 mm to about 6 cm, preferably in a range of about 4 mm to about 4 cm. The resilient element can be arranged in sections in the recess or can be arranged in the recess over the entire depth of the recess.

In preferred embodiments of the spectacle frame, the resilient element can extend at least in sections along the at least one temple or along a main extension direction of the at least one temple.

In other words, in preferred embodiments, the resilient element can extend essentially parallel to the at least one bracket or essentially parallel to the main extension direction of the at least one bracket.

As a result, when the at least one bracket is deflected or folded out into a normally open position, the resilient element is advantageously aligned with the bracket and towards the socket. As a result, restoring contact with the frame can be ensured, in particular when the normally open position is reached and when the at least one bracket is deflected or folded out beyond this.

In preferred embodiments of the spectacle frame, the resilient element can be arranged on the receptacle of at least one of the frame and the at least one temple, and can touch the other of the frame and the at least one temple in a normally open position of the temple.

As a result, the present spectacle frame has a particularly simple construction in order to provide a restoring force when the at least one temple is deflected relative to the frame, in particular when the at least one temple is deflected outside or away from the socket, which counteracts the deflection. The frame, at least one bracket and the resilient element are sufficient for this.

In other words, the resilient element is preferably arranged between the socket and the at least one bracket, in particular between the receptacle of one of the socket and the at least one bracket and the other of the socket and the at least one bracket. This advantageously simplifies the production of the glasses frame and the assembly of the resilient element.

In preferred embodiments of the spectacle frame, the resilient element can have a substantially constant outer diameter.

Further advantageously, a constant outer diameter of the resilient element enables installation of the resilient element to be independent of direction, and is thereby advantageously simplified in that the resilient element can be arranged both forwards and backwards on and in particular in the receptacle.

While a press fit ensures a secure fixation of the resilient element in of the recess, even with a comparatively small depth of the recess, a transition fit and a clearance fit enable particularly easy assembly and disassembly and are particularly suitable for a comparatively large depth of the recess.

In preferred embodiments of the spectacle frame, the resilient element can have an outer diameter of at least approximately 1 mm along its extension, preferably in the range from approximately 1 mm to approximately 3 mm, particularly preferably in the range from approximately 1 mm to approximately 2 mm.

In exemplary embodiments, the resilient element can have a solid material with an outer diameter of at least about 1 mm, preferably in the range from about 1 mm to about 3 mm, particularly preferably in the range from about 1 mm to about 2 mm.

The above-mentioned outer diameters advantageously make it possible to provide a sufficient restoring force, to ensure precise contact between the other part of the socket and the at least one bracket, and also ensure easy manufacturability, in particular by means of injection molding or by means of 3D printing.

In preferred embodiments of the spectacle frame, the resilient element can have or consist of an elastically resilient material.

This advantageously ensures that the restoring force is provided in an elastic manner, i.e. plastic deformation of the resilient element is prevented. As a result, a long-lasting, resilient spectacle frame can advantageously be provided.

In preferred embodiments of the spectacle frame, the resilient element can have or consist of at least two different elastically resilient materials. As a result, the resilient element can advantageously be provided with targeted material properties.

In addition, the resilient element can, for example, comprise at least two materials that are different in color and are each elastically resilient. This allows, for example, a degree of deflection of the at least one bracket relative to the frame to be visually displayed in that the resilient deflection reflects a color change at a predetermined point, relative to the joint, to the at least one bracket or to the frame. This can, for example, indicate a limit position up to which plastic deformation or damage to the frame, the at least one bracket, and/or the joint due to the deflection of the at least one bracket is or can be prevented. In addition, further optical indications and effects can advantageously be achieved using the resilient element, particularly in a passive manner.

In preferred embodiments of the spectacle frame, the resilient element can have at least one elastically soft material and at least one elastically rigid material, the elastically rigid material having a modulus of elasticity which is greater by a factor in the range from approximately 5.0 to approximately 100.0 as a modulus of elasticity of the elastically soft material, preferably larger by a factor of about 5.0 to about 50.0, in particular by a factor of about 8.0 to about 20.0.

In exemplary embodiments, the elastically soft material can have a hardness in the range from 10 Shore A to 95 Shore A, or in the range from 20 Shore D to 50 Shore D.

In preferred embodiments of the spectacle frame, the resilient element can have or consist of an elastomer, in particular have or consist of a thermoplastic elastomer. As a result, the resilient element can advantageously be provided with elastic properties in a simple manner. The elastomer also enables simple and repeatable production of the resilient element.

A thermoplastic elastomer is advantageously simple, precise and, in particular, inexpensive to produce, and can therefore be easily replaced, and therefore improves the repairability of the spectacle frame, in particular with regard to the elastically resilient properties between the temple and the frame. This advantageously increases the service life of the spectacle frame provided with the resilient element.

In preferred embodiments of the spectacle frame, the resilient element can have or consist of an elastomer or a thermoplastic elastomer, wherein the resilient element preferably has TPE or at least partially or completely consists of it, and / or wherein the resilient element preferably has TPU or at least partially or completely consists of it.

Because the resilient element has a thermoplastic elastomer, it is initially advantageous to produce it simply, precisely and, in particular, cost-effectively. This advantageously promotes the repairability of the glasses frame, especially with regard to the elastically resilient coupling between the temple and the frame.

If the resilient element has TPE and/or TPU, it can advantageously be manufactured in a simple, cost-effective manner and can also be provided with requirement-specific material properties by producing the resilient element integrally with the respective material or a predetermined combination of materials with predetermined manufacturing parameters.

In preferred embodiments of the spectacle frame, the receptacle can provide a cavity in the frame and/or in the temple, wherein the cavity in particular has a closed cross section, in particular transverse to the extent of the resilient element.

In other words, the receptacle can enclose the resilient element, in particular at least in sections. For example, the receptacle can form a cavity which at least partially encloses the resilient element.

Since the receptacle encloses the resilient element at least in sections, the resilient element can advantageously be mounted on the receptacle in a simple manner, for example by pushing in, plugging in or pressing in the resilient element.

In addition, the resilient element is advantageously held securely by the receptacle, so that the restoring force can be provided safely and accurately.

In preferred embodiments of the spectacle frame, the resilient element can have a closed cross-section or a U-, V-, C- or W-shaped cross-section.

The cross section of the resilient element is in particular a cross section in a plane transverse to the main extent of the resilient element, i.e. in particular a cross section transverse to an extent of the resilient element between the socket and the at least one bracket.

Because the resilient element has a closed cross section, it is advantageously stable, even with comparatively large elastic deflections. In addition, a closed cross section of the resilient element advantageously reduces the likelihood that the resilient element will jam on the receptacle.

A U-, V-, C- or W-shaped cross section of the resilient element allows It is advantageous to provide requirement-specific restoring, in particular elastically restoring, properties through the resilient element. In addition, a contoured cross-section, such as a U-, V-, C- or W-shaped cross-section, or even a triangular, square or other polygonal cross-section, in particular transverse to the main extent of the resilient element, makes it possible to form an assembly code with the receptacle , so that predetermined elastic properties can be ensured after assembly.

In further exemplary embodiments, an open cross-section, such as a U-, V-, C- or W-shaped cross-section can be formed in particular by one of the elastically soft material and the elastically stiff material, so that the open section of the cross-section with the others can be filled at least in sections by the elastically soft material and the elastically stiff material. As a result, the elastically resilient element can advantageously be provided with an application-specific resilient property.

In preferred embodiments of the spectacle frame, the resilient element can be at least partially or completely along its extent, in a cross section transverse to the main extent of the resilient element:

- a substantially circular cross section,

- a substantially oval cross section,

- a substantially elliptical cross section,

- a substantially triangular cross section,

- a substantially square cross-section, in particular a substantially square cross-section,

- a substantially hexagonal cross section, in particular substantially hexagonal cross section,

- a substantially hollow cylindrical cross section, and/or

- Have a substantially hollow-edge cross-section, for example a hollow square cross-section. Due to the respective cross section, the resilient element can advantageously be provided with a predetermined resilient property. In addition, due to its cross section, the resilient element can advantageously form a positive connection with the receptacle, in particular transversely to the resilient element. In exemplary embodiments, the receptacle can have an inner contour corresponding to the cross section of the resilient element.

A hollow cross section of the resilient element advantageously enables the resilient element to be compressed during assembly. Due to its resilient properties, in particular elastically resilient properties, the resilient element is preferably configured to resume its original shape after an initial assembly deformation or to adapt to an inner contour of the receptacle. This can advantageously make assembly easier. At the same time, a positive connection in the main extension direction of the elastically resilient element can be easily provided between the elastically resilient element and the receptacle.

In exemplary embodiments, the receptacle may have one or more projections on the inner contour of the receptacle. This one or more projections can be overcome in a simple manner by compressing a hollow cross section of the elastically resilient element during assembly, while after assembly a positive fit is provided which secures the elastically resilient element in particular against falling out. The resilient element can therefore be arranged captively on and in particular in the receptacle.

In preferred embodiments of the spectacle frame, the resilient element can have at least one groove or pocket. In alternative embodiments, instead of individual or multiple projections, a pressing ring, a locking ring, a pin or the like can be provided in order to advantageously secure the resilient element captively and in particular in a form-fitting manner on the receptacle to arrange.

In preferred embodiments of the spectacle frame, the resilient element can have a large number of pores.

In preferred embodiments of the spectacle frame, the resilient element can comprise a porous material.

Because the resilient element has pores and/or a porous material, the resilient element can advantageously be infiltrated in the pores with a material that deviates from its porous material, so that an application-specific resilient element can advantageously be provided, which is in particular due to the different material in is strengthened in the pores, i.e. becomes elastically stiffened, or becomes elastically softer.

In preferred embodiments of the spectacle frame, the resilient element can alternately have a mountain and a valley section along its main extension.

In other words, the resilient element can have several alternating mountain and valley sections along its main extension.

The mountain and valley sections in particular have different extents or widths transverse to the main extent of the resilient element.

The valley sections can be arranged or formed on one side of the resilient element, each between the mountain sections, or can be arranged or formed on opposite sides of the resilient element between the mountain sections. In other words, in exemplary embodiments, each of the valley sections can be on one side, transverse to the Main extension direction of the resilient element can be arranged, for example each of the valley sections can be arranged or formed on an upper side, on a lower side, on an inner side in the width direction or on an outer side in the width direction of the resilient element. In other exemplary embodiments, the valley sections can be arranged or formed on different sides, transverse to the main extension of the resilient element, and in particular arranged or formed alternately on opposite sides, transverse to the main extension direction of the resilient element, for example successively on an upper side , then on a bottom side, then again on the top side, and so on, or on a widthwise inner side, then on a widthwise outer side, then again on the widthwise inner side, and so on.

Through the alternating arrangement or formation of mountain and valley sections on the resilient element, application-specific elastically softer and elastically stiffer sections can be defined on the resilient element, for example in order to provide a deformation-dependent and / or deflection-dependent restoring force with the resilient element.

In exemplary embodiments, the mountain sections may have one of an elastically soft material and an elastically stiff material and the valley sections may be filled at least in sections with the other of the elastically soft material and the elastically stiff material.

As a result, the resilient element can advantageously be provided with restoring properties in a targeted and application-specific manner, with, for example, a deformation-dependent or deflection-dependent restoring force being able to be provided by the resilient element.

The deformation-dependent or deflection-dependent restoring force occurs depending on the degree of deformation of the resilient element, in particular depending on the deflection of the at least one bracket relative to the socket, and In contrast to conventional spring elements, describes in particular a non-linear behavior between restoring force and deformation. For example, the resilient element can have a phased force-distance behavior, wherein the resilient element has a first characteristic phase for a deformation that takes place essentially in a valley section of the resilient element, and for a deformation that occurs essentially in a mountain section of the Resilient element takes place, has a second characteristic phase, which has a force-path behavior that deviates from the first characteristic phase.

In preferred embodiments, the resilient element can be manufactured integrally with mountain and valley sections, in particular injection molded or printed using an additive process, for example 3D. As a result, a complex mechanical post-processing step can advantageously be omitted, so that a simple and cost-effective production of the spectacle frame is advantageously provided.

In preferred embodiments of the spectacle frame, the resilient element can have a plurality of pores and/or a groove or pocket in an area deformed due to the relative movement between the frame and the temple.

In other words, in preferred embodiments, the resilient element can have a plurality of pores and/or a groove or pocket in a contact area with the socket and/or with the at least one bracket. In other words, in preferred embodiments, the resilient element can have a plurality of pores and/or a groove or pocket on a distal end facing the socket and/or the at least one bracket.

As a result, the resilient element can advantageously be designed to be elastically soft and particularly resilient in an area that is primarily stressed due to a deflection of the at least one bracket relative to the socket.

In preferred embodiments of the glasses frame, the resilient Element have an elastically rigid material with a plurality of pores and / or with at least one groove or pocket, wherein preferably an elastically soft material is arranged in the pores of the plurality of pores and / or in the at least one groove or pocket.

As a result, the resilient element can advantageously be provided with a deformation-dependent or deflection-dependent restoring behavior.

In preferred embodiments of the spectacle frame, the resilient element can be arranged with a first end on the receptacle and with a second end, which is formed on the resilient element substantially opposite the first end, a stop for the other of the frame and the at least one Provide hangers.

In particular, in preferred embodiments, the resilient element can be formed in one piece in order to be arranged between the reception of one of the socket and the at least one bracket and the other of the socket and the at least one bracket.

This can advantageously make assembly easier, since an advantageously small number of individual parts are required to assemble a resilient spectacle frame.

In preferred embodiments of the spectacle frame, the other of the frame and the at least one temple can have a further receptacle, wherein the resilient element comprises a first resilient element which is arranged on the receptacle of the at least one of the frame and the at least one temple, and include a second resilient element, which is arranged on the further receiving of the other of the socket and the at least one bracket.

In preferred embodiments of the glasses frame, the first Resilient element and the second resilient element can be arranged in a normally open position of the bracket extending towards one another on the respective receptacle, in particular be arranged essentially aligned with one another on the respective receptacle.

In preferred embodiments of the spectacle frame, the receptacle can be a first recess in which the first resilient element is arranged at least in sections, and the further receptacle can be a second recess in which the second resilient element is arranged.

By arranging a plurality of resilient elements, which can be aligned with one another in particular in a normally open position of the bracket, and which can in particular each be arranged in a recess, a particularly long-lasting spectacle frame is advantageously provided, with secure contact between the two elastic resilient elements a deflection of the at least one bracket relative to the socket is ensured.

In alternative embodiments, the plurality of resilient elements can be arranged on the socket and the at least one bracket in such a way that when the at least one bracket is deflected relative to the socket, several resilient elements simultaneously provide a restoring force without touching each other. For example, the plurality of resilient elements can be arranged on the socket and the at least one bracket in such a way that the plurality of resilient elements each begin to provide a restoring force when the at least one bracket is deflected relative to the socket sequentially, i.e. one after the other. As a result, the plurality of resilient elements can, for example, be configured to provide an increasing restoring force with increasing relative deflection.

In preferred embodiments of the spectacle frame, the frame and the at least one bracket can be deflectably coupled by means of a swivel joint, in particular by means of a hinge. In preferred embodiments of the spectacle frame, the frame and the at least one temple can be coupled to one another in a torsion-proof manner.

In preferred embodiments of the spectacle frame, the at least one bracket can be pivotally coupled to the frame, in particular pivotally coupled to the frame about a vertical axis.

Through the above-described couplings, the deflection of the at least one bracket relative to the socket can advantageously be coupled in a targeted manner, within the scope of the degrees of freedom provided by the swivel joint, whereby in particular a torsion of the at least one bracket relative to the socket can be prevented.

In preferred embodiments of the spectacle frame, the resilient element can have a chamber which is at least partially filled with a fluid, in particular with a gel.

As a result, the resilient element can have, in addition to elastic properties, in particular damping properties, which advantageously increases the longevity of the spectacle frame.

In preferred embodiments of the glasses frame, a guide element can be arranged at least in sections on the receptacle, which is preferably stiffer than the resilient element.

By providing a guide element, the restoring force can advantageously be provided in a targeted manner by the resilient element via the guide element.

In preferred embodiments of the spectacle frame, the resilient element can cooperate with the guide element to provide a restoring force. In preferred embodiments of the spectacle frame, the guide element can have a stop in order to touch the frame opposite the holder and the at least one temple.

By providing a guide element, the restoring force can advantageously be provided in a targeted manner due to the interaction of the guide element with the resilient element, for example by both being arranged on and in particular in the receptacle, and an elastic deformation of the resilient element can be targeted.

In preferred embodiments of the spectacle frame, the guide element can accommodate the resilient element at least in sections.

In preferred embodiments of the spectacle frame, the resilient element can be designed in a normally open position of the temple so as not to provide any restoring force.

In preferred embodiments of the spectacle frame, the resilient element can be designed to provide a restoring force in a position that is deflected relative to a normally open position of the bracket, in particular in a position of the bracket that is deflected or pivoted outwards relative to a normally open position.

The exact position between the at least one bracket and the socket, i.e. the exact position of the at least one bracket relative to the socket, from which the resilient element provides a restoring force which counteracts a deflection of the at least one bracket relative to the socket, is advantageous due to the Arrangement of the resilient element on the holder can be adjusted. For example, the point in time from which the resilient element provides a restoring force can be adjusted by arranging the resilient element in a recess formed by the receptacle so that it to provide an exact value from the reception of one protruding from the socket and the at least one bracket to the other from the socket and the at least one bracket.

It is understood that if we are talking about a restoring force due to a deflection of the at least one bracket relative to the socket, this is a deflection of the at least one bracket outwards, in particular outwards in a width direction, in other words away from the socket , in other words from a normally open position of the at least one bracket to the outside, and in still other words away from the face of a user in the wearing position.

In contrast, when the at least one bracket is deflected relative to the frame into the folded position, which is usually used for space-saving transport of the glasses frame, for example in a case, no restoring force counteracting the deflection is provided.

In preferred embodiments of the spectacle frame, the resilient element and/or the guide element can be arranged on the receptacle in a form-fitting and/or cohesive and/or friction-locking manner.

In exemplary embodiments, the resilient element and/or the guide element can be arranged, in particular in a form-fitting manner, on the receptacle by means of a securing element, such as a securing ring, a pin, one or more projections.

Furthermore, in exemplary embodiments, the resilient element and/or the guide element can be arranged adhesively on the receptacle and in particular fastened.

In further exemplary embodiments, the resilient element and/or the guide element can form a press fit with the receptacle. While the positive and frictional arrangement advantageously ensures easy assembly and disassembly, the cohesive arrangement advantageously enables a long-lasting arrangement.

In preferred embodiments of the spectacle frame, the resilient element can be detachably arranged or fixed on the frame and/or the at least one temple.

This advantageously improves the repairability of the spectacle frame, and in particular of the resilient element.

In preferred embodiments of the spectacle frame, the resilient element for the frame and/or for the at least one temple can be arranged or fixed on the frame and/or the at least one temple in a non-destructively detachable manner.

In preferred embodiments of the spectacle frame, the resilient element can be detachable from the recess in a position pivoted inwards relative to a normally open position, in particular non-destructively detachable, preferably non-destructively detachable for the frame and the at least one temple.

In preferred embodiments of the glasses frame, the resilient element can be arranged captively on the receptacle.

For example, the resilient element can be arranged captively on the receptacle by a positive arrangement on the receptacle.

In preferred embodiments of the spectacle frame, the receptacle can comprise a projection, in particular a circumferential projection, preferably in cross section with a circumferential projection relative to the main extent of the recess, in order to at least captively protect the resilient element recorded in sections.

In preferred embodiments, when the at least one bracket is deflected relative to the socket, the resilient element can be designed to occupy a compressed volume, on the basis of which the restoring force is provided, in particular to counteract the deflection of the at least one bracket.

The resilient element thereby advantageously makes it possible to provide an elastically restoring force in a safe manner, which presses the at least bracket in particular back into the normally open position. In contrast, a spiral spring known from the prior art always has a substantially constant volume, since it only contracts axially, but only the distance between the turns decreases, but the volume does not change. While the resilient element according to the preferred embodiment thereby provides an elastically restoring force with particular repeatability, the spiral spring is particularly subject to the risk of tilting during its service life, as a result of which repeatable provision of an elastically restoring force is not ensured in the same way.

A further aspect of the present invention relates to glasses which comprise a spectacle frame according to the preceding aspect, wherein one or more spectacle lenses are arranged on the frame.

The spectacle lenses represent common spectacle lenses and are therefore not limited to any specific material, but can in particular be made of glass or plastic.

By the glasses comprising the glasses frame with the resilient element, which is arranged on the receptacle of the at least one of the frames and the at least one temple, easy assembly of resilient glasses can advantageously be ensured.

The above preferred, exemplary and alternatives Embodiments regarding the glasses frame and their effects relate equally to the glasses and vice versa.

In preferred embodiments of the glasses, a first bracket can be arranged at a first end of the frame and a second bracket can be arranged at a second end of the frame, the first bracket and/or the second bracket being elastically connected to the frame by means of one or more resilient elements is resiliently coupled.

Figures 1a, 1b, 1c, 2a and 2b show examples of different geometries of the resilient element. As shown in the figures, the resilient element 3 can in particular be a substantially elongated element which has significantly larger dimensions along its main extension direction HE than transversely to the main extension direction HE.

As shown by Figures 1a, 1b, 1c, 2a and 2b, the cross section of the resilient element 3 transverse to the main extension direction HE can have any shape and, for example, round, square, prismatic, and in particular as a solid material, i.e. as a solid body, or as a hollow body , i.e. hollow-edged, designed. Due to a substantially elongated shape, the resilient element 3 can be securely removed from a receptacle 6 (not in Figures 1a, 1b, 1c, 2a and 2b) are held and form a positive connection with the contour or shape of the resilient element 3, which, for example, prevents the resilient element 3 from rotating in the receptacle 6.

As shown by Figures 1a, 1b, 1c, 2a and 2b, the resilient element 3 can in particular have a continuous outside diameter, in particular a constant outside diameter.

Figures 3a, 3b and 3c show an exemplary resilient element 3, which has several valley sections 15 or pockets 15 along its main extension direction HE. The valley sections 15 alternate, in particular, with mountain sections, which are arranged along the main extension direction HE between the valley sections 15, and in exemplary embodiments can also be arranged at one or both distal ends of the resilient element.

Fig. 3b shows an example, wherein the resilient element 3 has pockets 15 or valley sections 15, and has an elastically stiff material 11, the pockets 15 or the valley sections 15 being at least partially or completely filled with an elastically soft material 10. In further exemplary embodiments, the pockets 15 or valley sections 15 can be arranged or formed annularly and in particular spaced apart from one another along the main extension direction HE on the resilient element 3, and, for example, be at least partially or completely filled with a material that differs from the material of the remaining resilient element 3.

Figures 4a, 4b and 4c as well as the other figures show an exemplary spectacle frame according to an embodiment of the present invention, or represent at least a section of an exemplary spectacle frame according to an embodiment of the present invention. The frame 1 can include an edge for one or more lenses, or can be a rimless frame. It is therefore understood that the present invention is therefore particularly generally suitable for the connection, in particular resilient connection, of a bracket 2 to a frame 1, without being limited to a specific type of spectacle frame or glasses.

In exemplary embodiments, in particular two brackets 2 can be arranged on the socket 1, in particular spaced apart in the width direction B, preferably opposite one another in the width direction B, on the socket 1.

As shown by way of example in Figures 4a, 4b and 4c, the joint by means of which the bracket 2 and the socket 1 are deflectably coupled to one another can be a hinge 4, which in particular allows a rotational movement about the height direction H. The hinge 4 can in particular provide or define a vertical axis that is essentially parallel to the height direction H, about which the bracket 2 can be deflected relative to the socket 1.

As shown in Figures 4a, 4b and 4c, the hinge 4 can be arranged offset, in particular in the width direction B, to align the bracket 2 and the resilient element 3. Figures 4a, 4b and 4c show possible arrangements of the resilient element 3 on a receptacle 6, which is provided by at least one of the socket 1 or the at least one bracket 2. The restoring force through the restorable element 3 can therefore in particular apply a moment around the hinge, counteracting a deflection of the bracket 2 relative to the socket 1.

As shown by Figures 4a, 4b and 4c, the resilient element 3 can be supported on one side in particular on and in particular in the receptacle 6, in particular with a first distal end along it

Support the main extension direction HE and in particular in the receptacle 6. At the same time, the resilient element 3 can be in the

Main extension direction HE touch the distal end opposite the element, which is opposite the receptacle 6, on or in which the resilient element 3 is supported.

As shown by Figures 4a, 4b and 4c, the receptacle 6 and in particular the resilient element 3 arranged on or in the receptacle 6 can have a corresponding stop 7 'opposite the receptacle 6, provided by the respective other of the holder 1 and the Bracket 2, aligned. 4c shows an alignment of the receptacle 6 and in particular of the resilient element 3 arranged thereon or therein with a corresponding stop 7 ', which is provided by an opposite further receptacle 6, in particular with a further resilient element 3 arranged thereon or therein. The aligned arrangement refers, as shown by Figures 4a, 4b and 4c, in particular to the normally open position of the glasses frame or the bracket 2, for example by a user after opening and before putting it on.

Fig. 4a shows an example of an embodiment, wherein the resilient element 3 is supported with a first distal end in the main extension direction HE on one side and in particular in the receptacle 6, which is provided by the bracket 2, and with a second distal end in the main extension direction HE, which is arranged or formed substantially opposite the first distal end, is configured to touch the socket 1. As a result, when the bracket 2 is deflected around the hinge 4, against the width direction B, i.e. downwards in the image of Figure 4a, the resilient element 3 being resiliently deformed or compressed at least in sections, the resilient element 3 can provide a restoring force, which Deflection of the bracket 2 counteracts.

4b shows an example of an embodiment, wherein the resilient element 3 is supported on one side with a first distal end in the main extension direction HE on and in particular in the receptacle 6, which is provided by the socket 1, and with a second distal end in the main extension direction HE, which is arranged or formed substantially opposite the first distal end, is configured to contact the bracket 2. As a result, when the bracket 2 is deflected around the hinge 4, against the width direction B, i.e. downwards in the image of Figure 4b, the resilient element 3 being resiliently deformed or compressed at least in sections, the resilient element can provide a restoring force which corresponds to the deflection of the bracket 2 counteracts.

Fig. 4c shows an example of an embodiment, wherein the resilient element 3 is supported with a first distal end in the main extension direction HE on one side and in particular in the receptacle 6, which is provided by the socket 1, and with a second distal end in the main extension direction HE , which is arranged or formed essentially opposite the first distal end, is supported on one side and in particular in the receptacle 6, which is provided by the bracket 2. As a result, when the bracket 2 is deflected around the hinge 4, against the width direction B, i.e. downwards in the image of Figure 4c, the resilient element 3 being resiliently deformed or compressed at least in sections, the resilient element can provide a restoring force which corresponds to the deflection of the bracket 2 counteracts. 4c, in exemplary embodiments a first resilient element 3 can be arranged on a receptacle 6, in particular on a first recess of one of the socket 1 and the bracket 2, and a second resilient element 3 on a further receptacle 6 , in particular be arranged at a second recess of the other of the socket 1 and the bracket 2. The two resilient elements 3 can be arranged in alignment with one another on the socket 1 and bracket 2 or, for example, can also be arranged offset from one another, in particular offset parallel to one another. The restoring force can therefore be provided, for example, by the contact and compression of both resilient elements 3 that are aligned with one another. In other exemplary embodiments, the restoring force can be provided by a simultaneous or time-staggered contact or by a simultaneous or time-staggered compression of the respective resilient elements 3 with the socket 1 and bracket 2 opposite in the main extension direction HE.

As shown by FIGS. 4a, 4b and 4c, the respective resilient element 3 can in particular be arranged at least in sections on the receptacle 6 or in the recess which forms the receptacle 6. Furthermore, the resilient element 3 can protrude or be arranged to project in particular with a contact section or stop 7 relative to the receptacle 6 or relative to the recess which forms the receptacle 6.

Figures 5a, 5b and 5c show exemplary embodiments, similar to the respective embodiment from Figures 4a, 4b and 4c, wherein the resilient element 3 is not arranged in a recess formed by the receptacle 6, but rather on an end face of the socket 1 and/or the bracket 2 is arranged, which faces the other of the socket 1 and the bracket 2. The receptacle 6 therefore represents an end face of the socket 1 and the bracket 2 facing the opposite element of the socket 1 and the bracket 2. Apart from that, for Fig. 5a, reference is made to the corresponding statements for Fig. 4a, for Fig. 5b, reference is made to the corresponding statements for Fig. 4b, and for Fig. 5c, reference is made to the corresponding statements for Fig. 4c.

Figures 6a and 6b show exemplary embodiments, similar to the embodiments of Figures 4a, 4b and 4c, wherein the resilient element 3 is arranged in a recess as a receptacle 6, wherein according to the embodiments in Figures 6a and 6b the resilient element 3 with a Guide element 5 interacts.

As shown by way of example in Figures 6a and 6b, the resilient element 3 can be arranged or attached in particular to a guide element 5, such as a pin. When the bracket 2 is deflected, the guide element 5 or the pin is pressed in the opposite direction to the width direction B towards the resilient element 3, so that through the deformation or compression of the resilient element 3, the resilient element 3 applies a restoring force, which moves the guide element s away from it Resilient element 3 pushes away, thereby generating a restoring moment which counteracts the deflection of the bracket 2.

Fig. 7 shows exemplary embodiments similar to those from Figures 4a, 4b and 4c, wherein the resilient element 3 is arranged in a recess as a receptacle 6. In the illustration in FIG. 7, the guide element 5 accommodates the resilient element 3 at least in sections. At the same time, the guide element 5 is arranged at least in sections on and in particular in the receptacle 6 designed as a recess. The resilient element 3 is thereby advantageously supported by the surrounding guide element 5.

When the bracket 2 is deflected, the guide element 5 or the guide sleeve is pressed further into the receptacle 6, in which the resilient element 3 is also arranged, in the opposite direction to the width direction B, with the resilient element 3 being disposed Element 3 is deformed or compressed within the framework of the inner contour of the guide element 5 or the guide sleeve and thereby applies a restoring force which presses the guide element 5 out of the receptacle 6 and thereby generates a restoring moment which counteracts the deflection of the bracket 2.

Fig. 8 shows an exemplary embodiment, wherein a resilient element 3 is provided with a plurality of pockets 15 or valley sections 15, which are arranged or formed on the resilient element 3 at a distance from one another in the main extension direction HE. The resilient element 3 is arranged on and in particular in the receptacle 6, which is designed as a recess. The resilient element s is specifically weakened due to the pockets 15 or the valley sections 15 and therefore enables particularly slight deformation or compression in the area of the pockets 15 or valley sections 15. The resilient element 3 can in particular have or consist of an elastically soft material 10 or an elastically stiff material 11. When the bracket 2 is deflected in the opposite direction to the width direction B, the resilient element 3 is deformed in the elastic region, in particular slightly deformed in the region of the pockets 15 or valley sections 15, and generates a restoring force due to the respective elastic material properties. Because the deformation takes place in the elastic range, the resilient element 3 can return to its starting position, as shown in FIG. 8.

9 shows an exemplary embodiment, wherein the resilient element 3 has or consists of a combination of different materials. 9 shows, by way of example, an elastically resilient element 3, which has an elastically stiff material 11 outside the pockets 15 or valley sections 15, and an elastically soft material 10 in the area of the pockets 15 or valley sections 15. By combining the different materials, in particular the materials that are elastically different from one another, the restoring force provided by the resilient element 3 can be advantageously adjusted.

Fig. 10 shows a further exemplary embodiment, wherein the resilient Element 3 is arranged on and in particular in the receptacle 6, which is designed as a recess, and wherein the resilient element 3 is at least partially filled with a fluid 12, such as a liquid or a gel.

Fig. 11 shows an exemplary embodiment, which in particular shows a normally open position of the spectacle frame or the temple 2 relative to the frame 1. The bracket 2 is shown in an undeflected position relative to the socket 1, the bracket 2 being in particular essentially parallel to the longitudinal direction L shown. Here, for example, the resilient element 3 shows no deformation and therefore does not cause any restoring force.

Fig. 12 shows an exemplary embodiment, which in particular shows a deflected position of the bracket 2 relative to the socket 1, the bracket

2 is deflected in particular in the opposite direction to the width direction B relative to the holder 1, in particular in relation to the normally open position, as shown in FIG. 11, in the opposite direction to the width direction B. Due to the deflection, the bracket 2 in particular assumes a position that is inclined relative to the longitudinal direction L shown. The resilient element 3 is, as shown in FIG is deformed.

Fig. 13 shows an exemplary embodiment, which shows the possibility of mounting the resilient element 3 by means of a fastening section 8. The fastening section 8 can in particular be integral with the resilient element

3 be made. In other exemplary embodiments, the fastening section 8 can be designed as an element separate from the resilient element 3 and can be attached to the receptacle 6 during assembly of the resilient element 3. The fastening section 8 shown in Fig. 13 forms a positive connection at a distal end of the resilient element 3 with a fastening device of the receptacle 6 that is complementary to the fastening section 8. The fastening section

8 can, for example, be a mushroom-shaped section or a clip, which is particularly detachably attached to the fastening device of the receptacle 6 in a form-fitting manner. The resilient element 3 can thereby advantageously be arranged captively on the receptacle 6, while interchangeability is ensured by another or in particular new resilient element 3.

14 shows an exemplary embodiment, wherein the resilient element 3 is fastened to the receptacle 6, in particular releasably fastened, by means of a fastening element 9, such as a pin or an inserted bolt.

Fig. 15 shows an enlarged section of a spectacle frame according to an embodiment of the present invention, wherein the receptacle 6 has a fastening element 9, such as a ring or, at an opening through which the resilient element 3 can be arranged on and in particular in the receptacle 6 a locking ring, which is inserted, in particular pressed, into the receptacle 6 after the resilient element 3 has been inserted. The fastener

9 therefore forms in particular a frictional connection and/or a positive connection with the receptacle 6 and therefore enables the resilient element 6 to be held securely, in particular to be held securely, while the interchangeability of the resilient element 3, for example for repairs, is still ensured.

Fig. 16 shows an enlarged section of a spectacle frame according to an embodiment of the present invention, wherein the fastening element 9 is formed integrally with the receptacle 6, i.e. integrally with the at least one of the frame 1 and the at least one bracket 2, and a narrowing or a collar, at an opening through which the resilient element 3 can be arranged on and in particular in the receptacle 6.
