Description

[0001] Glasses frame with resilient element

[0002] The present invention relates to a spectacle frame with a resilient hinge.

[0003] Eyeglass frames are known from the prior art, wherein a frame accommodates one or more lenses to improve a wearer's vision through the one or more lenses. To secure the eyeglasses to the wearer's head, a pair of temples is typically arranged on the frame so that, in a worn position, the eyeglasses rest and are held in place substantially against the nose and both ears. The temples are typically each connected to the frame by means of a spring hinge, which typically comprises a coil spring.

[0004] Spring hinges typically consist of a multitude of precisely manufactured individual parts that must be precisely mounted on the frame and / or temples. In addition, assembly often requires a special tool for assembling the coil spring and / or the numerous individual parts associated with the coil spring.

[0005] The object of the present invention is therefore to provide a simpler and in particular easier to assemble resilient coupling for coupling a temple to a frame of a spectacle frame.

[0006] The above-described object is achieved by the subject matter of the independent claims, and preferred embodiments are the subject matter of the dependent claims. One aspect of the invention relates to a spectacle frame comprising:

[0007] - a frame for one or more lenses;

[0008] - at least one bracket which is deflectably coupled to the frame;

[0009] - wherein at least one of the frame and the at least one temple has a receptacle;

[0010] - a resilient element which is arranged at least in sections on the holder,

[0011] -- wherein the resilient element provides a restoring force upon deflection of the temple relative to the frame and wherein the resilient element can be formed in particular from an injection-molded material or from a 3D-printed material.

[0012] The resilient element can, in particular, be arranged in sections on and at least partially in the receptacle. Furthermore, the resilient element can, in particular, protrude from the receptacle in particular regions. For example, the resilient element can protrude from the receptacle at least partially toward the other side of the frame and the at least one temple. In particular, the resilient element can protrude or protrude from the receptacle at least partially toward the other side of the frame and the at least one temple.

[0013] By providing the present spectacle frame with a receptacle on which the resilient element is arranged at least in sections, simplified assembly of the resilient element on the spectacle frame can advantageously be ensured. By providing the receptacle integrally with the frame and / or the at least one temple, the number of parts of the spectacle frame, in particular for the resilient coupling of the at least one temple to the frame, can further advantageously be reduced. This further advantageously improves assembly for the resilient coupling between the frame and the at least one temple. The restoring force provided by the resilient element counteracts, in particular, the deflection of the temple and can therefore advantageously counteract or prevent damage to the frame, the temple and / or the coupling, such as a pivot joint.

[0014] The resilient element can, in particular, be configured to provide a restoring force only upon deflection of the temple beyond a normally open position of the temple. The normally open position of the temple is, in particular, a position of the temple relative to the frame, wherein the temple is deflected approximately 90° relative to the frame. In other words, the normally open position of the temple is, in particular, a use position of the temple, into which the temple is folded or deflected in order to subsequently put on a pair of spectacles comprising the at least one temple and the frame.

[0015] The resilient element thus advantageously counteracts any deflection or opening of the bracket beyond the normally open position, i.e., beyond the use position, and cushions and, in particular, inhibits any deflection or opening beyond the normally open position, and, if necessary, returns the bracket to the normally open position. In particular, the bracket can be returned to the normally open position, i.e., the use position, if the bracket has been deflected beyond the normally open position.

[0016] In exemplary embodiments, one of the frame and the at least one temple can have the receptacle, and the other of the frame and the at least one temple can have a receptacle. In other words, in exemplary embodiments, both the frame and the at least one temple can have a receptacle for arranging the resilient element thereon.

[0017] In further exemplary embodiments, the frame may have a receptacle, in particular for each bracket pivotably coupled to the frame, for arranging the resilient element thereon or therein.

[0018] The receptacle for at least one of the frame and the at least one temple and / or the receptacle for the other of the frame and the at least one temple can, for example, be a recess for accommodating the resilient element at least in sections, a pin for sliding the resilient element on at least in sections, in particular by pressing or shrinking it on, and a clip or a groove for arranging the resilient element thereon. The receptacle(s) can, with the resilient element, in particular, configure a detachable fastening for the resilient element. This can advantageously facilitate maintenance as well as any necessary repair or replacement of the resilient element.

[0019] The various designs for arranging the resilient element by means of one or more receptacles advantageously make it possible to arrange the resilient element securely on the at least one temple and / or on the frame, and to apply a restoring force in a safe and targeted manner.

[0020] In exemplary embodiments, the resilient element may be a one-piece element that is both disposed on the receptacle of the at least one of the socket and the at least one temple, and configured to contact the other of the socket and the at least one temple to provide a restoring force.

[0021] 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 temple, and can also be positioned on and in particular in the receptacle such that the resilient element contacts the other of the socket and the at least one temple, in particular when the temple is deflected beyond the normally open position of the temple, 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 socket and the at least one temple. If the other of the socket and the at least one temple 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 temple.In exemplary embodiments, a first recess can be formed as a receptacle in at least one of the frame and the at least one bracket. Optionally, a second recess can additionally be formed as a receptacle in the other of the frame and the at least one bracket.

[0022] Due to the integral design of the receptacle(s) on or with the frame and the at least one temple, and in particular due to the design of the receptacle(s) as recess(es), the resilient element can advantageously be securely arranged on the frame and / or the at least one temple. Furthermore, a resilient coupling between a frame and a temple of a spectacle frame can advantageously be provided using a small number of parts, ensuring, in particular, comparatively simple assembly.

[0023] In further exemplary embodiments, the receptacle may be provided by or formed on one of the socket and the at least one bracket such that the receptacle is aligned with a stop provided by the other of the socket and the at least one bracket for the resilient element.

[0024] In particular, the resilient element can be arranged on or in the receptacle of one of the sockets and the at least one bracket in such a way that the resilient element is aligned with a stop provided by the other of the sockets and the at least one bracket for the resilient element, in particular for applying the resilient force.

[0025] This advantageously allows the number of parts for configuring the resilient coupling of the at least one temple to the frame to be reduced, which in turn advantageously simplifies the manufacture and assembly of the spectacle frame.

[0026] 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.

[0027] This makes it advantageous to produce the resilient element in a simple, cost-effective manner and with repeatable accuracy or, in the case of a 3D-printed material, also in an application-specific manner.

[0028] The resilient element can, in particular, comprise or consist of a plastic, such as an elastomer, a thermoplastic elastomer, a thermoplastic, a resin, or another plastic, or a mixture or blend thereof. Furthermore, the resilient element can, in particular, comprise or consist of a metal, such as a ferrous metal or a non-ferrous metal. Even further, the resilient element can, in particular, comprise or consist of an organic material, such as wood, cork, or mushrooms.Even further, the resilient element may in particular comprise or consist of a composite material, for example a fiber-reinforced plastic, in particular a hemp fiber-reinforced plastic, a flax fiber-reinforced plastic, a glass fiber-reinforced plastic, a carbon fiber-reinforced plastic, or a composite material comprising a combination of two or more of the other aforementioned materials.

[0029] In exemplary embodiments, the resilient element can be filled at least in sections with a fluid, such as a liquid or a gel.

[0030] In the following, various terms are used repeatedly; the following definitions should make them easier to understand. Frame: The frame as used here 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 into which one or more spectacle lenses can be mounted. The spectacle lenses can comprise a transparent or semi-transparent material commonly used for spectacles. The frame as used here represents a frame without spectacle lenses, but which is suitable for accommodating one or more spectacle lenses. The frame can therefore in particular comprise 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 by means of the lenses.

[0031] Eyeglass frame: In accordance with the above definition of the frame, the eyeglass frame as used here comprises in particular a frame and one or more temples, but not necessarily the one or more lenses.

[0032] Temple: The temple, as used here, represents a substantially elongated element which is arranged on the frame, in particular is pivotably or foldably coupled to the frame. The temples can, in particular, assume a folded position and an unfolded, normally open position, which can essentially correspond to a wearing position of a user. In the folded position, the temple is arranged with its main direction of extension essentially parallel to the frame or laterally adjacent to the frame. The main direction of extension of the temple can, in particular, essentially correspond to an imaginary line between a connection of the temple to the frame and a support point which the temple provides for an ear. Despite its substantially elongated extension, the temple can have a curved contour and / or a contour adapted to a face shape or head shape of a user.

[0033] In exemplary embodiments, the at least one bracket can be coupled to the frame in particular by means of a joint, for example by means of a pivot joint, a hinge or a fold, so that the at least one bracket can preferably be deflected or pivoted about the joint.

[0034] If a direction or an angle is described in the present case with the addition “essentially” or “approximately” or “approximately”, this addition generally means or is to be understood as meaning, in particular, a deviation from the direction or angle in question in the range from 0° to 5°.

[0035] If a spatial measure, a spatial ratio or any other ratio is described with the addition "essentially" or "approximately", this addition means or is to be understood in particular as a deviation from the measure or ratio in question in the range of 0% to 10%.

[0036] In preferred embodiments of the spectacle frame, the resilient element can:

[0037] - be a winding-free element and / or

[0038] - be a solid body; and / or

[0039] - be a non-spring element, in particular neither a spiral spring nor a leaf spring; and / or

[0040] - be a non-metallic element; and / or

[0041] - contain or consist of a plastic.

[0042] Because the resilient element is a coil-free element and / or a solid body, i.e., in particular, not a coiled wire-like element, the resilient element can be easily manufactured using injection molding or 3D printing. This also allows the resilient element to be manufactured with repeatable accuracy and cost-effectively. Because the resilient element is a non-spring element, i.e., in particular, neither a coil spring nor a leaf spring, the resilient element can be easily assembled, since conventional spring elements are usually assembled with a multitude of individual parts and may require special tools for assembly and / or disassembly, i.e., for replacement or repair.

[0043] Because the resilient element is a non-metallic element, and in particular comprises or consists of a plastic, the resilient element can advantageously be manufactured inexpensively and, in particular, recyclably. For example, a supposedly defective resilient element can be melted down and manufactured into a new resilient element. Manufacturing or production is advantageously carried out by injection molding or 3D printing. Furthermore, the preferred non-metallic design of the resilient element advantageously results in corrosion resistance. In particular, the resilient element can be resistant to salt water.

[0044] In preferred embodiments of the spectacle frame, the receptacle can be a first recess, wherein the resilient element is arranged at least in sections in the first recess and preferably extends out of the recess, in particular towards the other of the frame and the temple.

[0045] As a result, the resilient element can advantageously be arranged in a form-fitting manner on the receptacle and can furthermore advantageously be easily assembled and disassembled, for example for changing or replacing the resilient element.

[0046] Further advantageously, the resilient element can be advantageously aligned by means of the first recess towards the other of the frame and the at least one bracket, whereby the restoring force or effect can be advantageously adjusted.

[0047] In preferred embodiments of the spectacle frame, the resilient element can extend at least partially in the recess and have a constant outer diameter along its extension.

[0048] The essentially constant outer diameter of the resilient element advantageously prevents tilting or jamming of the resilient element in the recess, which can occur particularly with coil springs, which have a discontinuous outer diameter due to the windings. This also advantageously ensures a predetermined restoring force or effect.

[0049] The continuous outer diameter can be characterized in particular by an outer circumferential side that is continuous in cross-section.

[0050] 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.

[0051] 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 secure fixation of the resilient element in the recess, even with a comparatively shallow recess depth, a transition fit and a clearance fit enable particularly simple assembly and disassembly and are particularly suitable for a comparatively deep recess. The comparatively shallow depth of the recess can, for example, be in a range of approximately 3 mm to approximately 4 cm, preferably in a range of approximately 5 mm to approximately 2 cm, but is not limited thereto.The comparatively 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 is not limited thereto. The depth of the recess can generally be in a range from about 2 mm to about 6 cm, preferably in a range from about 4 mm to about 4 cm. The resilient element can be arranged in sections of the recess or can be arranged in the recess over the entire depth of the recess.

[0052] 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.

[0053] In other words, in preferred embodiments, the resilient element can extend substantially parallel to the at least one bracket or substantially parallel to the main extension direction of the at least one bracket.

[0054] As a result, the resilient element is advantageously aligned with the bracket and toward the socket when the at least one bracket is deflected or unfolded into a normally open position. This further ensures a resilient contact with the socket, particularly upon reaching the normally open position and upon deflection or unfolding of the at least one bracket beyond this position.

[0055] 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 contact the other of the frame and the at least one temple in a normally open position of the temple.

[0056] As a result, the present spectacle frame has a particularly simple construction for providing 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 outward or away from the frame, which counteracts the deflection. The frame, the at least one temple, and the resilient element are sufficient for this purpose.

[0057] In other words, the resilient element is preferably arranged between the frame and the at least one temple, in particular between the receptacle of one of the frame and the at least one temple and the other of the frame and the at least one temple. This advantageously simplifies the manufacture of the spectacle frame and the assembly of the resilient element.

[0058] In preferred embodiments of the spectacle frame, the resilient element may have a substantially constant outer diameter.

[0059] The essentially constant outer diameter of the resilient element advantageously prevents tilting or jamming of the resilient element in the recess, which can occur particularly with coil springs, which have a discontinuous outer diameter due to the windings. This also advantageously ensures a predetermined restoring force or effect.

[0060] Furthermore, a constant outer diameter of the resilient element advantageously enables assembly 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.

[0061] 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.

[0062] While a press fit ensures secure fixation of the resilient element in the recess, even with a comparatively small recess depth, a transition fit and a clearance fit enable particularly simple assembly and disassembly and are particularly suitable for a comparatively large recess depth.

[0063] In preferred embodiments of the spectacle frame, the resilient element can have an outer diameter of at least about 1 mm along its extension, preferably in the range of about 1 mm to about 3 mm, particularly preferably in the range of about 1 mm to about 2 mm.

[0064] In exemplary embodiments, the resilient element may comprise a solid material having an outer diameter of at least about 1 mm, preferably in the range of about 1 mm to about 3 mm, particularly preferably in the range of about 1 mm to about 2 mm.

[0065] The aforementioned outer diameters advantageously make it possible to provide a sufficient restoring force, to ensure precise contact between the frame and the at least one temple, and furthermore ensure easy manufacturability, in particular by means of injection molding or 3D printing.

[0066] In preferred embodiments of the spectacle frame, the resilient element may comprise or consist of an elastically resilient material.

[0067] This advantageously ensures that the restoring force is provided elastically, thus preventing plastic deformation of the resilient element. This advantageously provides a durable, resilient spectacle frame.

[0068] In preferred embodiments of the spectacle frame, the resilient element can comprise or consist of at least two different, elastically resilient materials. This allows the resilient element to be advantageously provided with specific material properties.

[0069] Furthermore, the resilient element can, for example, comprise at least two mutually different colored, each elastically resilient materials. This can, for example, visually indicate a degree of deflection of the at least one temple relative to the frame by the resilient deflection representing a color change at a predetermined location relative to the joint, the at least one temple, or the frame. This can, for example, indicate a limit position up to which plastic deformation or damage to the frame, the at least one temple, and / or the joint due to the deflection of the at least one temple is or can be prevented. Furthermore, further optical indications and effects can advantageously be realized using the resilient element, in particular in a passive manner.

[0070] In preferred embodiments of the spectacle frame, the resilient element can comprise at least one elastically soft material and at least one elastically stiff material, wherein the elastically stiff material has a modulus of elasticity which is greater by a factor in the range from about 5.0 to about 100.0 than a modulus of elasticity of the elastically soft material, preferably by a factor of about 5.0 to about 50.0, in particular by a factor of about 8.0 to about 20.0.

[0071] In exemplary embodiments, the elastically soft material may have a hardness in the range of 10 Shore A to 95 Shore A, or in the range of 20 Shore D to 50 Shore D.

[0072] In preferred embodiments of the spectacle frame, the resilient element can comprise or consist of an elastomer, in particular a thermoplastic elastomer. This allows the resilient element to be advantageously and easily provided with elastic properties. The elastomer also enables simple and repeatable production of the resilient element.

[0073] A thermoplastic elastomer is advantageously simple, precise, and especially cost-effective to manufacture, making it easy to replace. This improves the repairability of the spectacle frame, particularly with regard to the elastically resilient properties between the temple and the frame. This advantageously increases the service life of the spectacle frame equipped with the resilient element.

[0074] In preferred embodiments of the spectacle frame, the resilient element can comprise or consist of an elastomer or a thermoplastic elastomer, wherein the resilient element preferably comprises TPE or consists at least partially or entirely thereof, and / or wherein the resilient element preferably comprises TPU or consists at least partially or entirely thereof.

[0075] Because the resilient element is made of a thermoplastic elastomer, it is advantageously simple, precise, and, above all, cost-effective to manufacture. This advantageously promotes the repairability of the spectacle frame, particularly with regard to the elastically resilient coupling between the temple and the frame.

[0076] If the resilient element comprises 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 manufacturing the resilient element integrally with the respective material or a predetermined material combination with predetermined manufacturing parameters.

[0077] 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 extension of the resilient element.

[0078] In other words, the receptacle can, in particular, enclose the resilient element at least in sections. For example, the receptacle can form a cavity that encloses the resilient element at least in sections.

[0079] 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, inserting or pressing in the resilient element.

[0080] In addition, the resilient element is advantageously held securely by the holder so that the restoring force can be provided safely and precisely.

[0081] In preferred embodiments of the spectacle frame, the resilient element may have a closed cross-section, or a U-, V-, C- or W-shaped cross-section.

[0082] The cross section of the resilient element is in particular a cross section in a plane transverse to the main extension of the resilient element, i.e. in particular a cross section transverse to an extension of the resilient element between the frame and the at least one temple.

[0083] Because the resilient element has a closed cross-section, it is advantageously stable, even under comparatively large elastic deflections. Furthermore, a closed cross-section of the resilient element advantageously reduces the likelihood of the resilient element jamming on the mount.

[0084] A U-, V-, C-, or W-shaped cross-section of the resilient element advantageously enables the resilient element to provide requirement-specific restoring, particularly elastically restoring, properties. Furthermore, 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, particularly transverse to the main extension of the resilient element, allows for the formation of an assembly coding with the receptacle, thus ensuring predetermined elastic properties after assembly.

[0085] 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 can be at least partially filled with the other of the elastically soft material and the elastically stiff material. This advantageously provides the elastically resilient element with an application-specific resilient property.

[0086] In preferred embodiments of the spectacle frame, the resilient element can be at least partially or completely along its extension, in a cross section transverse to the main extension of the resilient element:

[0087] - a substantially circular cross-section,

[0088] - a substantially oval cross-section,

[0089] - a substantially elliptical cross-section,

[0090] - a substantially triangular cross-section,

[0091] - a substantially quadrangular cross-section, in particular a substantially square cross-section,

[0092] - a substantially hexagonal cross-section, in particular a substantially hexagonal cross-section,

[0093] - a substantially hollow cylindrical cross-section, and / or

[0094] - have a substantially hollow-edged cross-section, for example, a hollow square-shaped cross-section. The respective cross-section can advantageously provide the resilient element with a predetermined resilient property. Furthermore, 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.

[0095] A hollow cross-section of the resilient element advantageously allows 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 return to its original shape after an initial assembly deformation or to adapt to an inner contour of the receptacle. This can advantageously facilitate assembly. 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.

[0096] 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 easily overcome 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, in particular, captively on and in particular in the receptacle.

[0097] 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 compression ring, a retaining ring, a pin, or the like can be provided to advantageously arrange the resilient element captively and, in particular, in a form-fitting manner on the receptacle.

[0098] In preferred embodiments of the spectacle frame, the resilient element may have a plurality of pores.

[0099] In preferred embodiments of the spectacle frame, the resilient element may comprise a porous material.

[0100] By having pores and / or a porous material in the resilient element, the resilient element can advantageously be infiltrated with a material in the pores that differs from its porous material, so that an application-specific resilient element can advantageously be provided, which is in particular reinforced by the different material in the pores, i.e. is elastically stiffened, or becomes elastically softer.

[0101] In preferred embodiments of the spectacle frame, the resilient element can have alternating peak and valley sections along its main extension.

[0102] In other words, the resilient element can have several alternating peak and valley sections along its main extension.

[0103] In particular, the mountain and valley sections have different extensions or widths transverse to the main extension of the resilient element.

[0104] The valley sections can be arranged or formed on one side of the resilient element, between the peak sections, or arranged or formed on opposite sides of the resilient element between the peak sections. In other words, in exemplary embodiments, each of the valley sections can be arranged on a side transverse to the main extension direction of the resilient element, i.e., for example, each of the valley sections can be arranged or formed on a top side, on a bottom 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, transversely to the main extension of the resilient element, and in particular can be arranged or formed alternately on opposite sides, transversely to the main extension direction of the resilient element, for example successively on an upper side, then on a lower side, then again on the upper side, and so on, or on an inner side in the width direction, then on an outer side in the width direction, then again on the inner side in the width direction, and so on.

[0105] By alternating the arrangement or formation of peak and valley sections on the resilient element, elastically softer and elastically stiffer sections can be defined on the resilient element for specific applications, for example in order to provide a deformation-dependent and / or deflection-dependent restoring force with the resilient element.

[0106] In exemplary embodiments, the mountain sections may comprise 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.

[0107] As a result, the resilient element can advantageously be provided with restoring properties in a targeted and application-specific manner, whereby, for example, a deformation-dependent or deflection-dependent restoring force can be provided by the resilient element.

[0108] 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 temple relative to the frame, 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 exhibit a phase-by-phase force-displacement behavior, wherein the resilient element exhibits a first characteristic phase during a deformation that occurs essentially in a valley section of the resilient element, and a second characteristic phase during a deformation that occurs essentially in a peak section of the resilient element, which has a force-displacement behavior that differs from the first characteristic phase.

[0109] In preferred embodiments, the resilient element can be manufactured integrally with the peak and valley sections, in particular by injection molding or using an additive process, for example, 3D printing. This advantageously eliminates a complex mechanical post-processing step, thus advantageously providing a simple and cost-effective production of the spectacle frame.

[0110] In preferred embodiments of the spectacle frame, the resilient element can have a plurality of pores and / or a groove or pocket in a region deformed due to the relative movement between the frame and the temple.

[0111] 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 at a distal end facing the socket and / or the at least one bracket.

[0112] As a result, the resilient element can advantageously be designed to be elastically soft and particularly resilient in an area which is primarily stressed due to a deflection of the at least one temple relative to the frame.

[0113] In preferred embodiments of the spectacle frame, the resilient element can comprise an elastically stiff 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.

[0114] As a result, the resilient element can advantageously be provided with a deformation-dependent or deflection-dependent restoring behavior.

[0115] 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, can provide a stop for the other of the frame and the at least one temple.

[0116] In particular, in preferred embodiments, the resilient element can be formed in one piece in order to be arranged 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.

[0117] This can advantageously facilitate assembly, as a small number of individual parts are required to assemble a resilient spectacle frame.

[0118] 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 a second resilient element which is arranged on the further receptacle of the other of the frame and the at least one temple.

[0119] In preferred embodiments of the spectacle frame, the first resilient element and the second resilient element can be arranged on the respective receptacle extending towards one another in a normally open position of the temple, in particular can be arranged substantially flush with one another on the respective receptacle.

[0120] 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.

[0121] By arranging a plurality of resilient elements, which can be aligned with one another in particular in a normally open position of the temple, and which can each be arranged in a recess, a particularly durable spectacle frame is advantageously provided, wherein a secure contact of the two elastic resilient elements is ensured when the at least one temple is deflected relative to the frame.

[0122] In alternative embodiments, the plurality of resilient elements can be arranged on the frame and the at least one temple in such a way that, upon deflection of the at least one temple relative to the frame, several resilient elements simultaneously provide a restoring force without touching one another. For example, the plurality of resilient elements can be arranged on the frame and the at least one temple in such a way that, upon deflection of the at least one temple relative to the frame, the plurality of resilient elements each begin to provide a restoring force sequentially, i.e. one after the other in time. As a result, the plurality of resilient elements can be configured, for example, to provide an increasing restoring force with increasing relative deflection.

[0123] In preferred embodiments of the spectacle frame, the frame and the at least one temple can be coupled in a deflectable manner by means of a pivot 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-resistant manner.

[0124] In preferred embodiments of the spectacle frame, the at least one temple can be pivotally coupled to the frame, in particular pivotally coupled to the frame about a vertical axis.

[0125] By means of the couplings described above, the deflection of the at least one bracket relative to the frame can advantageously be coupled in a targeted manner, within the scope of the degrees of freedom provided by the rotary joint, wherein in particular a torsion of the at least one bracket relative to the frame can be prevented.

[0126] 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.

[0127] As a result, the resilient element can have, in addition to elastic properties, particularly damping properties, which advantageously increases the longevity of the spectacle frame.

[0128] In preferred embodiments of the spectacle frame, a guide element can be arranged at least in sections on the receptacle, which guide element is preferably stiffer than the resilient element.

[0129] By providing a guide element, the restoring force can advantageously be provided in a targeted manner from the resilient element via the guide element.

[0130] 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 for contacting the part of the frame opposite the receptacle and the at least one temple.

[0131] By providing a guide element, the restoring force can be advantageously provided in a targeted manner due to the interaction of the guide element with the resilient element, for example by arranging both on and in particular in the receptacle, and an elastic deformation of the resilient element can be targeted.

[0132] In preferred embodiments of the spectacle frame, the guide element can accommodate the resilient element at least in sections.

[0133] In preferred embodiments of the spectacle frame, the resilient element may be designed not to provide any restoring force in a normally open position of the temple.

[0134] In preferred embodiments of the spectacle frame, the resilient element can be designed to provide a restoring force in a position deflected relative to a normally open position of the temple, in particular in a position of the temple deflected or pivoted outward relative to a normally open position.

[0135] The precise position between the at least one temple and the frame, i.e. the precise position of the at least one temple relative to the frame, from which the resilient element provides a restoring force that counteracts a deflection of the at least one temple relative to the frame, can advantageously be adjusted by arranging the resilient element on the receptacle. 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 such that it protrudes by a precise amount from the receptacle of one of the frame and the at least one temple to the other of the frame and the at least one temple.

[0136] It is understood that when reference is made here to a restoring force due to a deflection of the at least one temple relative to the frame, this means a deflection of the at least one temple outwards, in particular in a width direction outwards, in other words away from the frame, in further other words outwards from a normally open position of the at least one temple, and in still other words away from the face of a user in the wearing position.

[0137] In contrast, when at least one temple is deflected relative to the frame into the folded position, which is usually used for space-saving transport of the spectacle frame, for example in a case, no restoring force is provided to counteract the deflection.

[0138] 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 material-fitting and / or friction-fitting manner.

[0139] In exemplary embodiments, the resilient element and / or the guide element can be arranged on the receptacle in a form-fitting manner by means of a securing element, such as a securing ring, a pin, one or more projections.

[0140] Furthermore, in exemplary embodiments, the resilient element and / or the guide element can be adhesively arranged and in particular fastened to the receptacle.

[0141] 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 engagement advantageously ensures easy assembly and disassembly, the material-to-material engagement advantageously enables a durable assembly.

[0142] In preferred embodiments of the spectacle frame, the resilient element can be detachably arranged or fixed to the frame and / or the at least one temple.

[0143] This advantageously improves the repairability of the spectacle frame, and in particular of the resilient element.

[0144] 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 to the frame and / or the at least one temple in a non-destructively detachable manner.

[0145] In preferred embodiments of the spectacle frame, the resilient element can be detachable from the recess in a position pivoted inwards compared to a normally open position, in particular detachable in a non-destructive manner, preferably for the frame and the at least one temple.

[0146] In preferred embodiments of the spectacle frame, the resilient element can be arranged on the receptacle in a captive manner.

[0147] For example, the resilient element can be arranged captively on the holder by means of a positive-locking arrangement on the holder.

[0148] In preferred embodiments of the spectacle frame, the receptacle can comprise a projection, in particular a circumferential projection, preferably a projection which is circumferential in cross section to the main extent of the recess, in order to receive the resilient element in a captive manner at least in sections.

[0149] In preferred embodiments, the resilient element can be designed to occupy a compressed volume upon deflection of the at least one bracket relative to the frame, on the basis of which the restoring force is provided, in particular to counteract the deflection of the at least one bracket.

[0150] The resilient element thus advantageously makes it possible to reliably provide an elastically restoring force which, in particular, pushes the bracket back into the normally open position. In contrast, a spiral spring known from the prior art always has a substantially constant volume, as it only contracts axially, whereby only the distance between the coils 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, whereby a repeatable provision of an elastically restoring force cannot be ensured in the same way.

[0151] A further aspect of the present invention relates to spectacles comprising a spectacle frame according to the preceding aspect, wherein one or more spectacle lenses are arranged on the frame.

[0152] The lenses are standard spectacle lenses and are therefore not limited to any specific material, but can be made of glass or plastic.

[0153] By comprising the spectacle frame with the resilient element, which is arranged on the receptacle of at least one of the frame and the at least one temple, a simple assembly of resilient spectacles can advantageously be ensured.

[0154] The above-mentioned preferred, exemplary and alternative embodiments with regard to the spectacle frame and their effects relate equally to the spectacles and vice versa.

[0155] In preferred embodiments of the spectacles, a first temple can be arranged at a first end of the frame and a second temple can be arranged at a second end of the frame, wherein the first temple and / or the second temple is elastically resiliently coupled to the frame by means of one or more resilient elements.

[0156] Embodiments of the invention are described in more detail below with reference to the accompanying figures. It is understood that the present invention is not limited to these embodiments, and that individual features of the embodiments can be combined to form further embodiments within the scope of the appended claims.

[0169] Figures 15, 16 each show a partial sectional view of a portion of a spectacle frame according to an embodiment of the invention.

[0170] Figures 1a, 1b, 1c, 2a, and 2b show various exemplary geometries of the resilient element. As shown in the figures, the resilient element 3 can, in particular, be a substantially elongated element that has significantly larger dimensions along its main extension direction HE than transversely to the main extension direction HE.

[0171] As shown in Figures 1a, 1b, 1c, 2a, and 2b, the cross-section of the resilient element 3 transverse to the main direction of extension HE can have any shape, for example, round, square, prismatic, and in particular can be formed as a solid material, i.e., as a solid body, or as a hollow body, i.e., hollow-edged. Due to a substantially elongated shape, the resilient element 3 can be securely held by a receptacle 6 (not shown in Figures 1a, 1b, 1c, 2a, and 2b) and form a positive connection with the contour or shape of the resilient element 3, which, for example, prevents the resilient element 3 from twisting in the receptacle 6.

[0172] As shown by Figures 1a, 1b, 1c, 2a and 2b, the resilient element 3 can in particular have a continuous outer diameter, in particular a constant outer diameter.

[0173] Figures 3a, 3b, and 3c show an exemplary resilient element 3, which has a plurality of valley sections 15 or pockets 15 along its main extension direction HE. The valley sections 15 alternate, in particular, with peak sections, which are arranged between the valley sections 15 along the main extension direction HE and, in exemplary embodiments, can also be arranged at one or both distal ends of the resilient element.

[0174] As illustrated by Figures 3a and 3c, the pockets 15 or valley sections 15 can be arranged or formed on one side transversely to the main extension direction HE on the resilient element 3 (Fig. 3c) as well as on both sides opposite each other, in particular alternately opposite each other on both sides, transversely to the main extension direction HE on the resilient element 3 (Fig. 3a).

[0175] As illustrated by Fig. 3b, the pockets 15 or valley sections 15 of the resilient element 3 can be filled at least in sections with a material, in particular at least in sections with a material that differs from the material of the remaining resilient element 3. Fig. 3b shows an example wherein the resilient element 3 has pockets 15 or valley sections 15 and an elastically stiff material 11, wherein the pockets 15 or the valley sections 15 are 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 on the resilient element 3 in a ring shape and in particular spaced apart from one another along the main extension direction HE, and can be at least partially or completely filled, for example, with a material that differs from the material of the remaining resilient element 3.

[0176] Figures 4a, 4b, and 4c, as well as the other figures, depict an exemplary spectacle frame according to an embodiment of the present invention, or depict at least a portion of an exemplary spectacle frame according to an embodiment of the present invention. The frame 1 may comprise a rim for one or more spectacle lenses, or may be a rimless frame. It is therefore understood that the present invention is particularly generally suitable for the connection, in particular a resilient connection, of a temple 2 to a frame 1, without being limited to a specific type of spectacle frame or spectacles.

[0177] In exemplary embodiments, in particular two temples 2 can be arranged on the frame 1, in particular spaced apart in the width direction B, preferably opposite one another in the width direction B, on the frame 1.

[0178] As shown by way of example in Figures 4a, 4b and 4c, the joint by means of which the bracket 2 and the frame 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 substantially parallel to the height direction H, about which the bracket 2 can be deflected relative to the frame 1.

[0179] As shown in Figures 4a, 4b, and 4c, the hinge 4 can be arranged offset, in particular in the width direction B, from the alignment of 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 provided by at least one of the frame 1 or the at least one bracket 2. The restoring force by the resilient element 3 can therefore, in particular, apply a moment around the hinge, counteracting a deflection of the bracket 2 relative to the frame 1.

[0180] As shown by Figures 4a, 4b and 4c, the resilient element 3 can be supported in particular on one side on and in particular in the receptacle 6, in particular with a first distal end along its

[0181] Main extension direction HE on and in particular in the receptacle 6. At the same time, the resilient element 3 can be supported with its in the

[0182] The distal end opposite the main extension direction HE touches the element which is opposite the receptacle 6 on or in which the resilient element 3 is supported.

[0183] As shown in Figures 4a, 4b and 4c, the receptacle 6 and in particular the resilient element 3 arranged on or in the receptacle 6 can be aligned with a corresponding stop 7' opposite the receptacle 6, provided by the respective other of the frame 1 and the temple 2. Fig. 4c shows an alignment of the receptacle 6 and in particular the resilient element 3 arranged on or in it with a corresponding stop 7' provided by an opposite further receptacle 6, in particular with a further resilient element 3 arranged on or in it. The aligned arrangement relates, as shown in Figures 4a, 4b and 4c, in particular to the normally open position of the spectacle frame or the temple 2, for example by a user after unfolding and before putting on.

[0184] 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 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 contact the socket 1. As a result, when the bracket 2 is deflected about the hinge 4, counter to the width direction B, i.e. downwards in the image of Figure 4a, wherein the resilient element 3 is resiliently deformed or compressed at least in sections, the resilient element 3 can provide a restoring force which counteracts the deflection of the bracket 2.

[0185] Fig. 4b 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 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 about the hinge 4, counter to the width direction B, i.e. downwards in the image of Figure 4b, wherein the resilient element 3 is resiliently deformed or compressed at least in sections, the resilient element can provide a restoring force which counteracts the deflection of the bracket 2.

[0186] 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 provided by the socket 1, and is supported with a second distal end in the main extension direction HE, which is arranged or formed substantially opposite the first distal end, on one side and in particular in the receptacle 6 provided by the bracket 2. As a result, when the bracket 2 is deflected about the hinge 4, counter to the width direction B, i.e. downwards in the image of Figure 4c, wherein the resilient element 3 is at least partially resiliently deformed or compressed, the resilient element can provide a restoring force which counteracts the deflection of the bracket 2. As can be seen from Fig.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 frame 1 and the temple 2, and a second resilient element 3 can be arranged on a further receptacle 6, in particular on a second recess of the other of the frame 1 and the temple 2. The two resilient elements 3 can be arranged in alignment with one another on the frame 1 and the temple 2 or, for example, 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 the two resilient elements 3 that are aligned with one another. In other exemplary embodiments, the restoring force can be provided by a simultaneous or temporally staggered contact orby a simultaneous or staggered compression of the respective resilient elements 3 with the one or more of the socket 1 and bracket 2 opposite one another in the main extension direction HE.

[0187] As shown in Figs. 4a, 4b, and 4c, the respective resilient element 3 can be arranged, in particular at least in sections, on the receptacle 6 or in the recess that forms the receptacle 6. Furthermore, the resilient element 3 can protrude or be arranged in a projecting manner, in particular with a contact section or stop 7, relative to the receptacle 6 or relative to the recess that forms the receptacle 6.

[0188] 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 is arranged on an end face of the socket 1 and / or the bracket 2, which faces the other of the socket 1 and the bracket 2. The receptacle 6 thus represents an end face of the socket 1 and the bracket 2 facing the respective opposite element of the socket 1 and the bracket 2. Apart from that, for Fig. 5a reference is made to the corresponding explanations for Fig. 4a, for Fig. 5b reference is made to the corresponding explanations for Fig. 4b, and for Fig. 5c reference is made to the corresponding explanations for Fig. 4c.

[0189] 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 cooperates with a guide element 5.

[0190] As shown by way of example in Figures 6a and 6b, the resilient element 3 can in particular be arranged or attached to a guide element 5, such as a pin. Upon deflection of the bracket 2, the guide element 5 or the pin is pressed toward the resilient element 3 opposite to the width direction B, so that due to the deformation or compression of the resilient element 3, the resilient element 3 exerts a restoring force that pushes the guide element 5 away from the resilient element 3, thereby generating a restoring moment that counteracts the deflection of the bracket 2.

[0191] Fig. 7 shows exemplary embodiments similar to those of Figs. 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 thus advantageously supported by the surrounding guide element 5.

[0192] When the bracket 2 is deflected opposite to the width direction B, the guide element 5 or the guide sleeve is pressed further into the receptacle 6, in which the resilient element 3 is also arranged, wherein the resilient element 3 is deformed or compressed within 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.

[0193] 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 3 is deliberately weakened due to the pockets 15 or the valley sections 15 and therefore allows particularly easy deformation or compression in the region 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 opposite to the width direction B, the resilient element 3 is deformed in the elastic range, particularly slightly deformed in the area of ​​the pockets 15 or valley sections 15, and generates a restoring force due to the respective elastic material properties. Because the deformation occurs in the elastic range, the resilient element 3 can return to its original position, as shown in Fig. 8.

[0194] Fig. 9 shows an exemplary embodiment, wherein the resilient element 3 comprises or consists of a combination of different materials. Fig. 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 region of the pockets 15 or valley sections 15. By combining the different materials, in particular the elastically different materials, the restoring force provided by the resilient element 3 can be advantageously adjusted.

[0195] 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.

[0196] Fig. 11 shows an exemplary embodiment, which in particular represents a normally open position of the spectacle frame or the temple 2 relative to the frame 1. The temple 2 is shown in a non-deflected position relative to the frame 1, wherein the temple 2 is in particular substantially parallel to the illustrated longitudinal direction L. The resilient element 3, for example, exhibits no deformation here and therefore does not exert any restoring force.

[0197] Fig. 12 shows an exemplary embodiment, which in particular shows a deflected position of the bracket 2 relative to the frame 1, wherein the bracket

[0198] 2 is deflected relative to the frame 1, in particular opposite to the width direction B, in particular opposite to the normally open position, as shown in Fig. 11. Due to the deflection, the bracket 2 assumes a position inclined relative to the illustrated longitudinal direction L. The resilient element 3 is, as shown in Fig. 12, in a deformed or compressed state, wherein the resilient element 3 is elastically deformed due to the stop 7 of the resilient element touching or pressing against the corresponding stop 7' of the frame 1.

[0199] 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

[0200] 3. In other exemplary embodiments, the fastening section 8 can be designed as a separate element 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

[0201] 8 can, for example, be a mushroom-shaped section or a clip, which is, in particular, releasably and positively attached to the fastening device of the receptacle 6. The resilient element 3 can thus advantageously be arranged on the receptacle 6 in a captive manner, while ensuring interchangeability with another or, in particular, new resilient element 3.

[0202] Fig. 14 shows an exemplary embodiment, wherein the resilient element 3 is fastened, in particular detachably fastened, to the receptacle 6 by means of a fastening element 9, such as a pin or an inserted bolt.

[0203] 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 a retaining ring, at an opening through which the resilient element 3 can be arranged on and in particular in the receptacle 6, which fastening element is inserted, in particular pressed, into the receptacle 6 after the resilient element 3 has been inserted.

[0204] 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 captively, while an exchangeability of the resilient element 3, for example for repair, is still ensured.

[0205] 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 at least one of the frame 1 and the at least one temple 2, and forms a constriction or a collar at an opening through which the resilient element 3 can be arranged on and in particular in the receptacle 6. In further exemplary embodiments, the receptacle 6 can have an additional or integrally formed fastening element 9 at a location other than the opening, for example, to engage with an annular groove of the resilient element 3, which is formed at a predetermined location along the main extension direction HE, and to fix the resilient element 3 in a form-fitting manner, in particular to fix it in a releasably form-fitting manner.
