Description

[Technical Field]

[0001] The invention relates to a spectacle hinge according to the preamble of the respective main independent claim and to a spectacle frame comprising such a hinge.

[0002] The hinge and frame are advantageously intended to be used in the manufacture of eyeglasses, in particular in the fabrication of eyewear pieces, in particular for connecting temple arms to the front of an eyeglass frame.

[0003] The hinge and the corresponding frame therefore fall within the eyewear industry, i.e. the manufacture of eyeglass frames and accessories and parts for eyeglasses. [Background technology]

[0004] As is known, in the eyewear field, hinges are used to articulate temple arms to the front of the frame.

[0005] Each hinge is conventionally formed for this purpose by two hinge elements hinged to one another, the first of which is fixed to the temple arm of the frame and the second to the front outer part (also known in the technical jargon as the "term end piece") or, in some cases, directly to one of the lenses.

[0006] More specifically, in a structurally simple hinge, the first hinge element, which represents the female element of the hinge, has a shoulder with a through hole formed therein that extends along the hinge axis.

[0007] Additionally, the second hinge element, representing the male element of the hinge, has a proximal shoulder projecting from the so-called end piece that carries a hinge pin engaged within the through-hole of the first hinge element to pivotally connect the first and second hinge elements.

[0008] The hinge pin may be secured onto the shoulder by welding, snap-fitting, or bonding, or the pin may be externally threaded and the shoulder may have an internally threaded hole, allowing the pin to be joined by threading it.

[0009] Typically, the first and second hinge elements are made of a metallic material, such as nickel silver, steel, or titanium.

[0010] In function, the hinge allows the temple arms to rotate between a closed position in which they are folded against the front of the eyeglasses, and an open position in which the temple arms are positioned substantially perpendicular to the front, allowing the user to wear the eyeglasses.

[0011] These hinges are particularly suitable for minimalist eyeglass frames, typically made from precious metals, where the hinge is integrally formed with the rest of the eyeglass frame, particularly the temple arms, in which case the frame may generally only include temple arms and nose pads fixed directly to the lenses.

[0012] The drawback of the above-mentioned known type of eyeglass hinge is due to the fact that the hinge is relatively simple in structure, so that the relative rotation between the two hinge elements cannot be easily prevented, which causes excessive movement of the frame parts. As a result, in this embodiment, the two hinge elements are easily separated inadvertently, and the hinge itself is not very sturdy in structure.

[0013] A further drawback lies in the fact that the hinge parts are often completely visible to the user and are not aesthetically appealing enough.

[0014] Another drawback of the known eyeglass hinges mentioned above is that dust and dirt can easily get into the hinge mechanism, making it more difficult to rotate. Summary of the Invention

[0015] In this context, the fundamental problem addressed by the present invention is therefore to overcome the drawbacks presented by the known types of solutions mentioned above, by providing an eyeglass hinge and an eyeglass frame comprising said hinge, which are able to limit and control the rotation between the parts of the eyeglasses.

[0016] A further object of the present invention is to provide an eyeglass hinge and eyeglass frame that are structurally strong enough.

[0017] A further object of the present invention is to provide an eyeglass hinge that prevents dust from entering the rotation mechanism.

[0018] A further object of the present invention is to provide a temple arm with reduced thickness and / or an eyeglass hinge that can be fixed forward.

[0019] A further object of the present invention is to provide an eyeglass hinge and eyeglass frame that is aesthetically pleasing.

[0020] A further object of the present invention is to provide an eyeglass hinge and eyeglass frame that is strong and durable over time.

[0021] A further object of the present invention is to provide an eyeglass hinge and eyeglass frame that are structurally simple to manufacture. [Brief explanation of the drawings]

[0022] The technical features of the present invention as set forth in the above-mentioned objects will be clearly apparent from the contents of the utility model registration claims set forth below, and its advantages will become more apparent from the following detailed description made with reference to the accompanying drawings illustrating several embodiments, purely for illustrative purposes and non-limiting.

[0024] With reference to the accompanying drawings, a hinge for eyeglasses of the present invention is generally designated 1.

[0025] The hinge 1 according to the invention is intended to be used for the manufacture of any type of eyeglass frame 10, in particular both frames made of metal and frames made of polymeric materials, such as acetate or materials suitable for 3D printing (in particular nylon).

[0026] The hinge 1 is advantageously suitable for articulating the two parts 11, 12 of the spectacle frame 10 relative to one another in a manner that is entirely known and conventional per se.

[0027] According to a preferred embodiment of the invention illustrated in FIG. 1, the hinge 1 is particularly suited to be realized integrally with a temple arm 11 of a metal eyeglass frame 10, preferably made of a precious metal, of the type known in the art as "rimless."

[0028] 1, the frame 10 conventionally comprises a bridge 13 connecting and directly fixed to two spectacle lenses 100. Furthermore, the frame 10 advantageously comprises two attachment elements 12, each directly fixed to a corresponding spectacle lens 100, at positions opposite the bridge 13, i.e., on the outer side of the eyeglasses. In particular, each attachment element 12 is snap-fit ​​into a groove made in the respective lens 100.

[0029] In particular, Figures 1 to 8 show a preferred embodiment in which the mounting element 12 comprises a particularly curved fixing portion 120 intended to be fixed in a groove of the lens 100, in particular on the posterior side of the lens.

[0030] 9 to 11 show a further embodiment in which the mounting element 12 comprises a front plate 121 from which the fixing part 120 advantageously extends. In this latter case, the fixing part 120 is advantageously intended to be fixed in a groove of the lens 100 on its front side, so that the front plate 121 covers the groove itself, resulting in a more aesthetically evocative appearance. Advantageously, the front plate 121 is shaped with decorative features.

[0031] Furthermore, the frame 10 advantageously comprises two temple arms 11 each connected to a respective mounting element 12 via a hinge 1 .

[0032] According to an alternative embodiment not illustrated, the frame 10 may also include a front part conventionally provided with two annular parts (or "rings") supporting corresponding lenses and connected in the middle by a bridge. In this case, the temple arms are pivoted via hinges 1 to the sides of the front part, more precisely to the two outer parts facing the rear of the spectacles, known in technical terms as "endpieces." Advantageously, the endpieces thus substantially correspond to the mounting elements 12 of rimless frames.

[0033] In either of the above cases, functionally, the temple arms 11 can move between a closed position in which they are folded over the lenses 100 or the front portion of the frame 10, thanks to the aforementioned hinges 1, and an open position in which the temple arms 11 are positioned substantially perpendicular to the lenses 100 or the front portion.

[0034] According to the invention, the eyeglass hinge 1 comprises a first hinge element 2 intended to be mounted on a first part 11 of an eyeglass frame 10. The first hinge element 2 comprises an extension portion 21 configured to be fixed to the first part 11 of the eyeglass frame 10, and a hinge portion 22 connected to the extension portion 21 and defining at least one hole 23 extending along the hinge axis X.

[0035] In particular, the hinge portion 22 comprises an inner surface 25 which advantageously defines the aforementioned aperture 23 .

[0036] According to a preferred embodiment illustrated in FIG. 7, the hinge portion 22 of the first hinge element 2 is helical in shape and comprises at least one transition 24 defining the aforementioned hole 23 .

[0037] Advantageously, the hinge part 22 comprises one to four transition parts 24, preferably one to three transition parts 24. For example, in Figure 7 a hinge 1 is shown in which the hinge part 22 comprises two transition parts 24.

[0038] In particular, the rotational direction of the conversion portion 24 can be either clockwise or counterclockwise depending on the placement of the hinge 1 on the frame 10, i.e., the side on which the hinge 1 is mounted. Furthermore, the rotational direction of the conversion portion 24 can be varied for aesthetic purposes.

[0039] Similarly, the deployment direction of the conversion portion 24 can be either upward or downward.

[0040] More particularly, the terms "rotation direction" and "deployment direction" shall be understood to refer to paths defined by the extension of the transition portion 24 around and along the hinge axis X, respectively, starting from the end of the hinge portion 22 fixed to the extension portion 21 of the first hinge element 2.

[0041] Of course, the hinge portion 22 may have any other shape without departing from the scope of protection of the present invention.

[0042] The hinge 1 further comprises a second hinge element 3 which is intended to be mounted on the second part 12 of the eyeglass frame 10 and comprises a support part 31 configured to be fixed to the second part 12 of the eyeglass frame 10.

[0043] Furthermore, the hinge 1 comprises a hinge pin 4 mounted on the support portion 31 of the second hinge element 3 and inserted into a hole 23 of the first hinge element 2 to rotatably connect the first hinge element 2 and the second hinge element 3 around the hinge axis X.

[0044] In particular, the hinge pin 4 extends between a lower end 40 which is advantageously mechanically connected to the support portion 31 and an upper end 41 in a free state.

[0045] More particularly, the hinge pin 4 is made integral with the second hinge element 3, preferably integral with the support part 31 of the second hinge element 3. For example, the integral second hinge element 3 and hinge pin 4 can be obtained by investment casting or by plastic deformation by stamping.

[0046] According to an alternative embodiment, the hinge pin 4 is manufactured separately and fixed to the support part 31, for example by welding, adhesive bonding or snap-fitting.

[0047] More specifically, the lower end 40 of the hinge pin 4 is fixed to the support portion 31. For example, one end of the support portion 31 is snap-fitted into a recess provided in the lower end 40 of the hinge pin 4.

[0048] Naturally, the hinge pin 4 may be fixed to the second hinge element 3 in any other suitable manner without departing from the scope of protection of the present invention.

[0049] Advantageously, the hinge pin 4 comprises at least one guide groove 43, in particular an outer surface 42 that substantially defines a thread. Furthermore, the hinge part 22 advantageously engages with its inner surface 25 in the aforementioned guide groove 43. If the hinge part 22 is helical in shape, the transition part 24 itself engages in the guide groove 43.

[0050] In this way, the hinge part 22 is more resistant to disengagement from the hinge pin 4, as this engagement prevents simple sliding along the hinge axis X.

[0051] Of course, other methods may be used to prevent or impede disengagement of the hinge portion 22 without departing from the scope of protection of the present invention.

[0052] According to the idea underlying the invention, the hinge 1 further comprises a cover element 5 arranged at least partially on the hinge portion 22 of the first hinge element 2 .

[0053] In this way, the hinge 1 is reinforced by the cover element 5 and is more rigid and resistant.

[0054] Furthermore, this cover element 5 advantageously prevents dust from getting between the first hinge element 2 and the hinge pin 4 and / or second hinge element 3 and interfering with the rotation of the hinge 1 .

[0055] Advantageously, the cover element 5 has the additional benefit of being more aesthetically evocative of the hinge 1, since the mechanism is hidden. Furthermore, the exterior of the cover element 5 can be decorated with inlaid gemstones, enamel, or any other decorative surface treatment.

[0056] To this end, the cover element 5 is preferably made of a precious jewellery metal such as gold, silver, platinum or their respective alloys.

[0057] Preferably, the first and second hinge elements 2, 3 are also made of a metallic material, preferably a noble metal such as gold, silver, platinum or an alloy thereof. Naturally, without departing from the scope of protection of the present invention, the hinge 1 and / or any of its parts may also be made of a non-noble metal, for example nickel-silver, steel or titanium.

[0058] According to the invention, the cover element 5 is further provided with an opening 51 through which the extension portion 21 of the first hinge element 2 extends.

[0059] This feature advantageously prevents the cover element 5 from becoming disengaged from the first hinge element 2 of the hinge 1 .

[0060] The cover element 5 is advantageously mounted on the first hinge element 2 after the first hinge element 2 has been connected (in a manner known per se) to the second hinge element 3 via the hinge pin 4 .

[0061] In operation, assembly is performed by first inserting the extension portion 21 of the first hinge element 2 through the opening 51 in the cover element 5. The cover element 5 is then slid until it reaches the hinge portion 22, and then moved, e.g., rotated, until it is positioned over the hinge portion 22 itself.

[0062] Advantageously, the cover element 5 is mechanically connected to the hinge portion 22 of the first hinge element 2 by means of a snap fit.

[0063] Advantageously, the cover element 5 is rotationally integral with the hinge portion 22 of the first hinge element 2 .

[0064] According to a further embodiment illustrated in Figures 9 to 11, the cover element 5 is mechanically connected to the second hinge element 3 and / or the hinge pin 4, in particular to the latter, by means of a screw 6 and is therefore advantageously only indirectly connected to the hinge part 22 of the first hinge element, in particular in a rotatable manner.

[0065] In this case, the cover element 5 is advantageously rotationally integral with the hinge portion 22 of the second hinge element 3 .

[0066] According to all embodiments of the invention illustrated in the accompanying drawings, the cover element 5 is advantageously concave and in particular defines a housing seat 52 in which the hinge portion 22 of the first hinge element 2 is at least partially housed.

[0067] More particularly, the housing seat 52 is sized to substantially fit the hinge portion 22 of the first hinge element 2 .

[0068] Advantageously, the cover element 5 comprises at least one abutment portion 53 configured to abut against the support portion 31 of the second hinge element 3 in order to prevent rotation of the first hinge element 2 relative to the second hinge element 3 in use, particularly when the hinge 1 is in a fully open position.

[0069] In this way, the maximum rotation of the hinge 1 can be advantageously controlled.

[0070] More specifically, as can be seen in particular in Figures 2 and 5, the cover element 5 is provided with a peripheral edge 54 having at least a first edge portion 541 arranged at a first level L1 identified along the hinge axis X.

[0071] Furthermore, the peripheral edge 54 advantageously comprises at least a second edge portion 542 disposed at a second level L2, determined along the hinge axis X, different from the first level L1.

[0072] In particular, the term "level" is to be understood as the midpoint of the protrusion of the first edge portion 541 or the second edge portion 542 on the hinge rotation axis X of the hinge 1. Specifically, if the first edge portion 541 or the second edge portion 542 is on a plane perpendicular to the hinge rotation axis X, its protrusion on this rotation axis X is itself a point. Alternatively, if the first edge portion 541 or the second edge portion 542 is not on a plane perpendicular to the hinge rotation axis X, its protrusion on this rotation axis X is a segment, and its level is defined as the midpoint of this segment.

[0073] More specifically, first edge portion 541 and second edge portion 542 are staggered, i.e., offset from one another.

[0074] Advantageously, the peripheral edge portion 54 further comprises an intermediate edge portion 543 which extends to connect the first edge portion 541 and the second edge portion 542 and is in particular arranged at an angle relative to the first edge portion 541 and the second edge portion 542.

[0075] Preferably, the abutment portion 53 of the cover element 5 comprises an intermediate edge portion 543 by means of which it advantageously abuts against the support portion 31 of the second hinge element 3 .

[0076] According to a preferred embodiment of the invention, as shown for example in Figure 4, the cover element 5 comprises a cylindrical portion 55 arranged around the hinge portion 22 of the first hinge element 2. In particular, the cylindrical portion 55 extends with an axis substantially coinciding with the hinge axis X.

[0077] Advantageously, the opening 51 in the cover element 5 is formed at least partially on the cylindrical portion 55 .

[0078] According to a preferred embodiment illustrated in the accompanying drawings, the opening 51 is substantially circular in shape.

[0079] Obviously, without departing from the scope of protection of the present invention, the opening 51 may have an elongated shape and may for example extend from (or up to) the peripheral edge 54 of the cover element 5. In this latter case, the opening 51 may also be formed as a groove or notch on the cover element 5.

[0080] According to a further embodiment of the invention, for example illustrated in FIGS. 9-11, the opening 51 has an elongated shape and extends from the periphery 54 of the cover element 5, and is in particular formed as a groove on the cover element 5.

[0081] 9 and 11, the opening 51 advantageously comprises an insertion portion 510 configured to insert the extension portion 21 of the first hinge element 2 into the opening 51 itself by sliding. In particular, the insertion portion 510 extends at least partially parallel to the hinge axis X.

[0082] Advantageously, the opening 51 further comprises a rotating portion 511 extending from the insertion portion 510, along which the extension portion 21 can slide when opening and closing the hinge 1. In particular, the rotating portion 511 extends circumferentially around the hinge axis X.

[0083] In this case, the abutment portion 53 of the cover element 5 is preferably configured to abut against the extension portion 21 of the first hinge element 2 in use, in particular when the hinge 1 is in a fully open position, to prevent rotation of the second hinge element 3 relative to the first hinge element 2.

[0084] The abutment portion 53 of the cover element 5 therefore advantageously comprises the terminal surface of the rotating portion 511 .

[0085] 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 pin 4 .

[0086] According to a further embodiment of the invention illustrated in Figures 9 to 11, a through hole (not shown) is formed in the dome portion 56, through which at least the shank of the screw 6 is inserted for attaching the cover element 5, in particular to the hinge pin 4.

[0087] Obviously, without departing from the scope of protection of the invention, the cover element may have any shape or size, also depending on its secondary decorative purpose.

[0088] Also forming the object of the invention is a spectacle frame 10 advantageously equipped with a hinge 1 as described above.

[0089] Frame 10 is preferably a rimless frame of the type previously described and illustrated, for example but not limited to, FIG.

[0090] According to the present invention, the eyeglass frame 10 comprises a first part 11 and a second part 12. Preferably, according to the example shown in Fig. 1, the first part 11 of the eyeglass frame 10 corresponds to a temple arm, and the second part 12 of the eyeglass frame 10 corresponds to a lens mounting element 100.

[0091] In particular, the attachment element 12 to the lens 100 may engage directly in a snap-fit ​​manner within a lateral groove in the lens 100 itself, or may correspond to the so-called end piece or front portion of conventional eyeglasses.

[0092] The frame 10 further comprises a hinge 1 for eyeglasses having any of the features described above and therefore will not be described in further detail. The hinge 1 is positioned to connect the first and second parts 11, 12.

[0093] In the following, reference will be made to an example in which the first part 11 of the spectacle frame 10 is actually constituted by a temple arm and the second part 12 by a mounting element of the frame. However, without departing from the scope of protection of the invention, one can envisage embodiments in which the two parts are reversed, in particular in which the first hinge element 2 of the hinge is mounted on the mounting element and the second hinge element 3 is mounted on the temple arm.

[0094] According to the basic concept of the invention, the extension 21 of the first hinge element 2 is made integral with the first part 11 .

[0095] Furthermore, the support portion 31 of the second hinge element 3 is made integral with the second part 12 .

[0096] In this way, the parts of the hinge 1 are already made integrally, preferably in the same process as the other parts of the frame 10, so that the entire frame 10 can be manufactured in fewer steps.

[0097] In operation, the cover element 5 of the hinge 1 is then mounted to the first hinge element 2 by first passing the entire temple arm 11 through the opening 51 in the cover element 5 and sliding the cover element 5 until it reaches the hinge part 22. The subsequent steps are advantageously those already described above.

[0098] Preferably, the first and second hinge elements 2, 3, and advantageously also the temple arms 11 and the attachment element 12, are made of metal, preferably a precious metal such as gold, silver, platinum or alloys thereof. Obviously, without departing from the scope of protection of the present invention, the frame 10 and / or any of its parts may also be made of a non-precious metal such as nickel-silver, steel or titanium.

[0099] Obviously, without departing from the scope of protection of the present invention, at least a part of the first and second hinge elements 2, 3, the temple arms 11, the attachment element 12 and / or the cover element 5 may also be made of a polymer material such as acetate.

[0100] Thus, the device thus conceived achieves its intended purpose.
