Description

Title of the invention: Eyeglass hinge and eyeglass frame comprising said hinge Scope

[0001] The present invention relates to a hinge for spectacles and a spectacle frame comprising said hinge.

[0002] The hinge and the frame concerned are advantageously intended to be used in the manufacture of glasses and, in particular, in the manufacture of eyewear components, in particular to connect a temple to a front part of the glasses frame.

[0003] Consequently, the hinge in question, and its frame, falls within the industrial sector of eyewear, that is to say the manufacture of eyeglass frames and accessories and components for eyeglasses. State of the art

[0004] As is known, in the eyewear industry, hinges are used to articulate the temples relative to the front piece of a frame.

[0005] For this purpose, each hinge traditionally consists of two articulation elements, pivoting relative to each other, of which a first element is fixed to a branch of the frame and a second element is fixed to a lateral part of the front piece (also known as the "tenon" in the technical jargon of the sector) or, in some cases, directly to one of the lenses.

[0006] In more detail, in hinges simpler from the point of view of their architecture, the first articulation element, which represents the female element of the hinge, is provided with a shoulder on which a through hole is made extending along a hinge axis.

[0007] Furthermore, the second articulation element, which represents the male element of the hinge, is provided with a base shoulder projecting beyond the tenon. Such a base shoulder carries a mounted hinge pin, which is engaged inside the through hole of the first articulation element, to couple the first and second articulation elements to each other in a rotational manner.

[0008] The hinge stem can be fixed to the shoulder by welding, fitting or gluing, or the stem can be externally threaded and the shoulder can include an internally threaded hole, so the stem can be coupled by screwing.

[0009] Generally, the first and second articulation elements are made of metallic material, for example nickel silver, steel or titanium.

[0010] Functionally, the hinges allow the temples to pivot between a closed position, in which they are gathered on the front piece of the glasses, and an open position, in which they take a position substantially at a right angle to the front piece suitable for allowing the user to wear the glasses.

[0011] These hinges are particularly suitable for eyeglass frames with a minimalist design, generally made of precious metal, in which the hinge is formed as a single piece with the rest of the eyeglass frame, especially with the temple. In this case, the frame generally comprises only the temples and the nose pad, which are directly attached to the lenses.

[0012] A drawback of the known type of spectacle hinges described above is that their simple construction does not allow for easy blocking of the relative rotation between two hinge elements, resulting in excessive movement of the frame components. Consequently, this feature facilitates accidental decoupling of the two hinge elements and makes the hinge less structurally robust.

[0013] Another disadvantage is that the hinge components are often completely visible to the user and are not sufficiently aesthetically pleasing.

[0014] Another disadvantage of the known spectacle hinges described above is that dust or dirt can easily get into the hinge mechanism, making rotation more difficult. Description of the invention

[0015] In this situation, the problem underlying the present invention is therefore to overcome the disadvantages arising from the aforementioned known type solutions by providing a hinge for glasses and a glasses frame including said hinge, which make it possible to limit and control the rotation between the components of the glasses.

[0016] Another objective of the present invention is to provide a glasses hinge and a glasses frame that are structurally sufficiently strong.

[0017] Another objective of the present invention is to provide a hinge for glasses that prevents dust and dirt from entering the rotation mechanism.

[0018] Another objective of the present invention is to provide a hinge for glasses that can be fixed to thin temples and / or front pieces.

[0019] Another objective of the present invention is to provide a spectacle hinge and spectacle frame that can be appreciated from an aesthetic point of view.

[0020] Another objective of the present invention is to provide a glasses hinge and a glasses frame that are strong and durable over time.

[0021] Another objective of the present invention is to provide a hinge for spectacles and a spectacle frame that are structurally simple to manufacture.

[0022] The present invention therefore relates to a hinge for eyeglasses, comprising: • a first articulation element, intended to be mounted on a first component of a spectacle frame, comprising:

[0023] - an elongated part, configured to be fixed to the first component of said eyeglass frames;

[0024] - a hinged part, which is connected to the elongated part and defines at least one opening, extending along a hinge axis; • a second articulation element, intended to be mounted on a second component of said spectacle frame, and comprising a support part, configured to be fixed to the second component of said frame; • a hinge rod, which is mounted on the support part of said second articulation element and is inserted into the orifice of said first articulation element to rotationally connect said first articulation element and said second articulation element around said hinge axis;

[0025] said eyeglass hinge further comprising a cover element, which is positioned to at least partially cover the hinge part of said first articulation element;

[0026] said cover element being provided with an opening through which extends the elongated part of said first articulation element.

[0027] According to a particular feature of the invention, said cover element is concave in shape and defines a housing seat in which the hinge part of said first articulation element is at least partially disposed.

[0028] According to a particular feature of the invention, said cover element comprises a cylindrical part arranged around the hinge part of said first articulation element.

[0029] According to a particular feature of the invention, the opening of said cover element is made at least partially on said cylindrical part.

[0030] According to a particular feature of the invention, said opening has an elongated shape and extends from the peripheral edge of said cover element.

[0031] According to a particular feature of the invention, said opening includes an insertion section, configured to insert by sliding the elongated part of said first articulation element into said opening in question.

[0032] According to a particular feature of the invention, said opening further comprises a rotation section extending from said insertion section and in which the elongated part of said first articulation element is capable of sliding during the opening and closing of said hinge.

[0033] According to a particular feature of the invention, the cover element is rotationally fixed to the hinge part of the second articulation element and said cover element includes at least a stop part configured to butt against the elongated part of said first articulation element in order to block, during use, the rotation of the second articulation element relative to the first articulation element.

[0034] According to a particular feature of the invention, the stop part of said cover element includes an end face of the rotation section of said opening.

[0035] The present invention also relates to a spectacle frame comprising: • a first component, preferably corresponding to a branch; • a second component, preferably corresponding to an attachment element for a glass; • a hinge for eyeglasses as described above, placed in connection between said first component and said second component, in which: • the elongated part of said first articulation element is made in one piece with said first component, and • the support part of said second articulation element is made in one piece with said second component.

[0037] Detailed description of some favorite realization examples

[0038] With reference to the attached drawings, the eyeglass hinge 1 which is the subject of the present invention has been referred to globally as 1.

[0039] The hinge 1, according to the present invention, is intended to be used for the manufacture of frames 10 for glasses of all types, in particular frames made of metal and frames made of polymer material, for example acetate or materials suitable for processing by 3D printing (in particular nylon).

[0040] The hinge 1 is advantageously suited to articulate, in a manner known in itself and traditional, mutually with respect to each other two components 11,12 of a frame 10 of spectacles.

[0041] According to the preferred embodiment of the invention, illustrated in [Fig. 1], the hinge 1 is particularly suitable for being made in one piece with a branch 11 of a metal eyeglass frame 10, preferably made of precious metal, of the type referred to in the jargon as "frameless", i.e. without a frame.

[0042] In more detail, with reference to the example in [Fig. 1], the frame 10 comprises, in a conventional manner, a bridge 13 positioned to connect two spectacle lenses 100 and fixed directly to them. Furthermore, the frame 10 advantageously comprises two attachment elements 12, each directly fixed to a corresponding spectacle lens 100, in a position opposite to the bridge 13, i.e., external to the spectacles. In particular, each attachment element 12 is fitted into a slot formed on the lens 100 itself.

[0043] In particular, an embodiment is shown in figures 1 to 8 in which the attachment element 12 includes a fixing part 120, in particular curved, intended to be fixed in the slot of the glass 100, in particular at the rear of the latter.

[0044] Furthermore, another embodiment is shown in Figures 9 to 11, in which the attachment element 12 comprises a front plate 121 from which the fixing portion 120 advantageously extends. In this latter case, the fixing portion 120 is advantageously designed to be fixed in the slot of the glass 100 at the front thereof, so that the front plate 121 covers the slot, thus providing a more aesthetically pleasing appearance. Advantageously, the front plate 121 is shaped with a decorative form.

[0045] In addition, the frame 10 advantageously comprises two arms 11, each connected, via the hinge 1, to the respective attachment element 12.

[0046] According to another alternative embodiment not illustrated, the mount 10 may also comprise, in a manner that is itself traditional, a front piece provided with two annular parts (or "circles") adapted to support the corresponding lenses and connected at the central part by the bridge. In this case, the temples pivot by means of hinges 1 on the sides of the front piece and, more precisely, on two of its lateral parts oriented towards the rear of the glasses and known in the technical jargon of the sector as the tendon. Advantageously, the tendon thus corresponds substantially to the attachment element 12 of a frameless frame.

[0047] In both cases above, from a functional point of view, the arms 11 can move, thanks to said hinges 1, between a closed position, in which they are gathered at the level of the lenses 100 or on the front piece of the frame 10, and an open position, in which the arms 11 take a position substantially at a right angle to the lenses 100 or to the front piece.

[0048] According to the invention, the eyeglass hinge comprises a first articulation element 2, intended to be mounted on a first component 11 of an eyeglass frame 10. The first articulation element 2 comprises an elongated portion 21, configured to be fixed to the first component 11 of the eyeglass frame 10, and a hinge portion 22, which is connected to the elongated portion 21 and defines at least one orifice 23, extending along a hinge axis X.

[0049] In particular, the hinge part 22 includes an inner surface 25, which advantageously delimits said orifice 23.

[0050] According to the preferred embodiment illustrated in [Fig.7], the hinge part 22 of the first articulation element 2 is spiral and includes at least one loop 24, which defines said orifice 23.

[0051] Advantageously, the hinge part 22 comprises one to four loops 24, preferably one to three loops 24. For example, [Fig.7] shows a hinge 1 in which the hinge part 22 comprises two loops 24.

[0052] In particular, the direction of rotation of the loops 24 can be either clockwise or counterclockwise, depending on the arrangement of the hinge 1 in the frame 10, i.e., the side on which it is mounted. Furthermore, the direction of rotation of the loops 24 can vary according to aesthetic requirements.

[0053] Similarly, the direction of development of the loops 24 can be ascending or descending.

[0054] In more detail, the expressions "direction of rotation" and "direction of development" will be understood as referring to the path defined by the extension of the loops 24, around the hinge axis X and along the hinge axis X, respectively, from the end of the hinge part 22 fixed to the elongated part 21 of the first articulation element 2.

[0055] Of course, without departing from the scope of the invention, the hinge part 22 can be of any other shape.

[0056] The hinge 1 further includes a second articulation element 3, intended to be mounted on a second component 12 of the frame 10 of glasses, and comprising a support part 31, configured to be fixed to the second component 12 of the frame 10.

[0057] In addition, the hinge 1 includes a hinge rod 4, which is mounted on the support part 31 of the second articulation element 3 and inserted into the orifice 23 of the first articulation element 2 to rotationally connect the first articulation element 2 and the second articulation element 3 around the hinge axis X.

[0058] In particular, the hinge rod 4 extends between a lower end 40, advantageously mechanically connected to the support part 31, and a free upper end 41.

[0059] In more detail, the hinge stem 4 is made in one piece with the second articulation element 3, preferably with the support portion 31 of the latter. For example, the second articulation element 3 and the hinge stem 4 in one piece are obtained by microcasting or by plastic deformation through hammering.

[0060] According to one embodiment, the hinge rod 4 is made separately and fixed to the support part 31, for example by welding, gluing or fitting.

[0061] In more detail, the lower end 40 of the hinge rod 4 is fixed to the support part 31. For example, an end piece of the support part 31 is inserted by fitting into a cavity obtained on the lower end 40 of the hinge rod 4.

[0062] Of course, without departing from the scope of the present invention, the hinge rod 4 can be fixed to the second articulation element 3 in any other suitable way.

[0063] Advantageously, the hinge stem 4 comprises a lateral surface 42, which defines at least one guide groove 43, i.e., in particular, substantially a thread. Furthermore, the hinge portion 22 advantageously engages with its own inner surface 25 in said guide groove 43. If the hinge portion 22 is spirally shaped, the loops 24 themselves engage in the guide groove 43.

[0064] Thus, the hinge part 22 is more difficult to decouple from the hinge rod 4, because simple sliding only along the hinge axis X is prevented by such an engagement.

[0065] Of course, without departing from the scope of the invention, the decoupling of the hinge part 22 can be blocked or further hindered in other ways.

[0066] According to the idea underlying the present invention, the hinge 1 further comprises a cover element 5, which is positioned to at least partially cover the hinge part 22 of the first articulation element 2.

[0067] Thus, the hinge 1 is stronger and more resistant because it is reinforced by the cover element 5.

[0068] In addition, such a cover element 5 advantageously prevents dust and dirt from infiltrating between the first articulation element 2 and the hinge rod 4 and / or the second articulation element 3 and from hindering the rotation of the hinge 1.

[0069] Advantageously, the cover element 5 has the additional advantage of making the hinge 1 more aesthetically pleasing, since the mechanism is concealed. Furthermore, the exterior of the cover element 5 can be decorated with set gemstones, enamel, or any other decorative surface finish or machining.

[0070] For this purpose, the cover element 5 is preferably made of precious metal for jewelry, for example gold, silver, platinum or their alloys.

[0071] Preferably, the first and second articulation elements 2, 3 are also made of a metallic material, preferably precious, for example gold, silver, platinum, or their alloys. Of course, without departing from the scope of the invention, the hinge 1 and / or any of its parts may also be made of a non-precious metallic material, for example nickel silver, steel, or titanium.

[0072] According to the invention, the cover element 5 is further provided with an opening 51 through which extends the elongated part 21 of said first articulation element 2.

[0073] Such an aspect advantageously prevents the cover element 5 from decoupling from the first articulation element 2 of the hinge 1.

[0074] The cover element 5 is advantageously mounted on the first articulation element 2 after the coupling (in a manner known in itself) of the latter to the second articulation element 3 via the hinge rod 4.

[0075] From an operational point of view, the assembly is first made by inserting the elongated part 21 of the first articulation element 2 through the opening 51 of the cover element 5. The latter is then slid to the hinge part 22, and then moved, for example by rotation, until it is positioned to cover the hinge part 22 itself.

[0076] Advantageously, the cover element 5 is mechanically connected by interlocking to the hinge part 22 of the first articulation element 2.

[0077] Advantageously, the cover element 5 is rotationally fixed to the hinge part 22 of the first articulation element 2.

[0078] According to another embodiment, illustrated in figures 9 to 11, the cover element 5 is mechanically connected by means of a screw 6 to the second articulation element 3 and / or to the hinge rod 4, in particular to the latter, and is therefore advantageously connected only indirectly to the hinge part 22 of the first articulation element, in particular in a rotational manner.

[0079] In this case, the cover element 5 is advantageously rotationally fixed to the hinge part 22 of the second articulation element 3.

[0080] According to all embodiments of the invention illustrated in the attached figures, the cover element 5 is advantageously concave in shape and defines in particular a housing seat 52 in which the hinge part 22 of the first articulation element 2 is at least partially disposed.

[0081] In more detail, the housing seat 52 fits substantially into the hinge part 22 of the first articulation element 2.

[0082] Advantageously, the cover element 5 includes at least a stop portion 53 configured to butt against the support portion 31 of the second articulation element 3 to block, during use, the rotation of the first articulation element 2 relative to the second articulation element 3, in particular when the hinge 1 is in the maximum open position.

[0083] Thus, it is advantageously possible to control the maximum rotation of the hinge 1.

[0084] In more detail, as can be seen in particular in figures 2 and 5, the cover element 5 is provided with a peripheral edge 54 which includes at least a first edge section 541, arranged on a first level L1 identified along the hinge axis X.

[0085] In addition, the peripheral edge 54 advantageously comprises at least one second edge section 542, arranged on a second level L2 identified along the hinge axis X, different from the first level L1.

[0086] In particular, the term "level" shall be understood as the midpoint of the projection of the first edge section 541 or the second edge section 542 onto the axis of rotation X of the hinge 1. More precisely, if the first edge section 541 or the second edge section 542 lies on a plane perpendicular to the axis of rotation X, their projection onto this axis of rotation X is itself a point. If, on the other hand, the first edge section 541 or the second edge section 542 does not lie on a plane perpendicular to the axis of rotation X, their projection onto this axis of rotation X is a segment, and their level is defined as the midpoint of this segment.

[0087] More clearly, the first edge section 541 and the second edge section 542 are offset, that is to say misaligned with respect to each other.

[0088] Advantageously, the peripheral edge 54 further comprises an intermediate edge section 543, which extends in connection between the first edge section 541 and the second edge section 542 and which is in particular arranged in an inclined manner with respect to the first edge section 541 and the second edge section 542.

[0089] Preferably, the stop part 53 of the cover element 5 includes the intermediate edge section 543, with which it advantageously acts as a stop against the support part 31 of the second hinge element 3.

[0090] According to the preferred embodiment of the invention, shown for example in [Fig.4], the cover element 5 comprises a cylindrical part 55 arranged around the hinge part 22 of the first articulation element 2. In particular, the cylindrical part 55 extends along an axis coinciding substantially with the hinge axis X.

[0091] Advantageously, the opening 51 of the cover element 5 is made at least partially on the cylindrical part 55.

[0092] According to the preferred embodiment, illustrated in the attached figures, the opening 51 is substantially circular in shape.

[0093] Of course, without departing from the scope of the present invention, the opening 51 can also have an elongated shape and, for example, extend from (or to) the peripheral edge 54 of the cover element 5. In this latter case, the opening 51 can therefore also be made in the form of a slot or a notch on the cover element 5.

[0094] For example, according to the other embodiment of the invention illustrated in figures 9 to 11, the opening 51 has precisely an elongated shape and extends from the peripheral edge 54 of the cover element 5, in particular by being made in the form of a slot on the cover element 5.

[0095] Furthermore, as can be seen in Figures 9 and 11, the opening 51 advantageously includes an insertion section 510, configured to insert the elongated portion 21 of the first hinge element 2 into the opening 51 itself by sliding. In particular, the insertion section 510 extends at least partially parallel to the hinge axis X.

[0096] Advantageously, the opening 51 further includes a rotation section 511 extending from the insertion section 510 and in which the elongated part 21 is capable of sliding during the opening and closing of the hinge 1. In particular, the rotation section 511 extends circumferentially around the hinge axis X.

[0097] In this case, the stop part 53 of the cover element 5 is preferably configured to come against the elongated part 21 of the first articulation element 2 to block, during use, the rotation of the second articulation element 3 relative to the first articulation element 2, in particular when the hinge 1 is in the maximum open position.

[0098] Consequently, the stop portion 53 of the cover element 5 advantageously comprises an end face of the rotation section 511.

[0099] Advantageously, the cover element 5 further comprises a dome portion 56 extending from the cylindrical portion 55 to cover the upper end 41 of the hinge stem 4.

[0100] According to the other embodiment of the invention illustrated in figures 9 to 11, a through orifice (not illustrated) is made in the domed part 56, through which at least the screw shank 6 is inserted for fixing the cover element 5, in particular to the hinge shank 4.

[0101] Of course, without departing from the scope of the present invention, the cover element can be of any shape or size, depending also on its secondary decorative purpose.

[0102] A spectacle frame 10, which advantageously includes the hinge 1 described above, is also the subject of the present invention.

[0103] Mount 10 is preferably, but not exclusively, a frameless mount of the type described above and illustrated as an example in [Fig.1].

[0104] According to the invention, the eyeglass frame 10 comprises a first component 11 and a second component 12. Preferably, according to the example shown in [Fig.1], the first component 11 of the eyeglass frame 10 corresponds to a temple and the second component 12 of the eyeglass frame 10 corresponds to an attachment element for a lens 100.

[0105] In particular, the attachment element 12 to a lens 100 can be inserted directly by fitting into a lateral slot in the lens 100 itself, or correspond to the tenon or the front piece of traditional glasses.

[0106] The frame 10 further comprises a hinge 1 for spectacles having one of the characteristics described above and which is therefore not described in further detail. The hinge 1 is placed in connection between the first and second elements 11, 12.

[0107] In what follows, reference will be made to the example in which the first component 11 of the frame 10 of glasses consists of a temple and the second component 12 consists of the attachment element of the frame 10. However, embodiments in which the two components are reversed, and in particular embodiments in which the first articulation element 2 of the hinge is mounted on the attachment element and the second articulation element 3 is mounted on the temple, may be envisaged, without departing from the scope of the invention.

[0108] According to the idea underlying the invention, the elongated part 21 of the first articulation element 2 is made in one piece with the first component 11.

[0109] In addition, the support part 31 of the second articulation element 3 is made in one piece with the second component 12.

[0110] Thus, it is possible to produce the entire mount 10 in fewer steps, since the parts of the hinge 1 are already made in one piece and, preferably, with the same machining as the other parts of the mount 10.

[0111] In this case, from an operational point of view, the cover element 5 of the hinge 1 is mounted on the first hinge element 2 by first passing the entire arm 11 through the opening 51 of the cover element 5 and sliding the latter until it reaches the hinge part 22. The following steps are advantageously those already described above.

[0112] Preferably, the first and second hinge elements 2, 3, and even advantageously the temples 11 and the attachment elements 12, are made of a metallic material, preferably precious, for example gold, silver, platinum, or their alloys. Of course, without departing from the scope of the invention, the frame 10 and / or any of its parts may also be made of a non-precious metallic material, for example nickel silver, steel, or titanium.

[0113] Of course, without departing from the scope of the present invention, at least part of the first and second articulation elements 2, 3, the arms 11, the attachment elements 12 and / or the cover element 5 can also be made of polymer material, such as acetate, for example.

[0114] The invention thus conceived therefore achieves the predetermined objectives.
