Description

Field of invention

[0001] The present invention relates to a hinge for eyeglasses and an eyeglass frame comprising the aforementioned hinge according to the preamble of the corresponding independent main claims.

[0002] The hinge and frame in question are advantageously designed to be used in the manufacture of eyeglasses and, in particular, in the manufacture of components for eyeglasses, especially to connect a temple to a central part of the eyeglass frame.

[0003] Therefore, the hinge and frame in question fall under the spectacle industry sector, i.e., the manufacture of spectacle frames as well as spectacle accessories and components. State of the art

[0004] As is well known, hinges are used in the eyewear sector to flexibly attach the temples to the middle part of a frame.

[0005] For this purpose, each hinge traditionally consists of two joint elements rotatably mounted together, a first element being attached to a bracket of the frame and a second element being attached to a lateral section of the middle part (also known in the industry as the "end piece") or in some cases directly to one of the lenses.

[0006] Specifically, in the case of simpler hinge designs, the first joint element, which represents the receiving element of the hinge, is provided with a projection on which a through-opening extending along a pivot axis is attached.

[0007] Furthermore, the second joint element, which forms the plug-in element of the hinge, is provided with a base projection extending from the end piece. When assembled, this base projection carries a hinge pin that engages in the through-hole of the first joint element to rotatably connect the first and second joint elements.

[0008] The hinge pin can be attached to the socket by welding, mortising or gluing; alternatively, the pin can have an external thread and the socket can have an opening with an internal thread, allowing the pin to be connected by screwing.

[0009] Generally, the first and second joint elements are made of a metal material, e.g. nickel silver, steel or titanium.

[0010] Functionally, the hinges allow the temples to rotate between a closed position, in which they are folded together on the middle part of the glasses, and an open position, in which they assume a position essentially at right angles to the middle part, suitable for allowing the user to put on the glasses.

[0011] These hinges are particularly suitable for eyeglass frames with a minimalist aesthetic, usually made of precious metal, where the hinge is manufactured as a single piece with the rest of the frame, especially the temples. In this case, the frame generally only includes the temples and nose bridge, which are attached directly to the lenses.

[0012] One disadvantage of the hinges for eyeglasses described above, of the known type, is that the relative simplicity of their construction does not allow for a simple way to block the relative rotation between the two joint elements of the hinge, causing excessive stretching of the frame components. Consequently, this aspect not only makes the two joint elements more easily separated accidentally, but also makes the hinge itself less structurally stable.

[0013] Another disadvantage lies in the fact that the hinge components are often fully visible to the user and not sufficiently appealing from an aesthetic point of view.

[0014] Another disadvantage of the previously described known hinges for glasses lies in the fact that dust or dirt can easily penetrate the hinge mechanism, making it difficult to rotate. Presentation of the invention

[0015] In this situation, the problem underlying the present invention is therefore to overcome the disadvantages shown by the above-mentioned solutions of a known type by providing a hinge for eyeglasses and an eyeglass frame comprising the above-mentioned hinge, which make it possible to limit and control the rotation between the eyeglass components.

[0016] Another objective of this invention is to provide a hinge for eyeglasses and an eyeglass frame that are sufficiently stable in terms of construction.

[0017] Another aim of this invention is to provide a hinge for eyeglasses that prevents dust and dirt from entering the rotating mechanism.

[0018] Another objective of this invention is to provide a hinge for eyeglasses that can be attached to temples and / or midsections of low thickness.

[0019] Another aim of this invention is to provide a hinge for eyeglasses and an eyeglass frame that are aesthetically pleasing.

[0020] Another aim of this invention is to provide a hinge for eyeglasses and an eyeglass frame that are durable and long-lasting.

[0021] Another objective of this invention is to provide a hinge for eyeglasses and an eyeglass frame that are easy to manufacture in terms of design. Brief description of the drawings

Detailed description of some preferred examples of execution

[0023] With reference to the accompanying drawings, the hinge for eyeglasses, which is the subject of this invention, is designated in its entirety by 1.

[0024] The hinge 1 according to the invention is intended to be used for the manufacture of eyeglass frames 10 of any type, in particular for frames made of metal as well as for frames made of polymer material, for example of acetate or materials suitable for processing with 3D printing (in particular nylon).

[0025] The hinge 1 is advantageously suitable for connecting two components 11, 12 of a spectacle frame 10 in a jointly articulated manner that is generally known and traditional.

[0026] According to the in Fig. In the preferred embodiment of the invention shown in Figure 1, the hinge 1 is particularly suitable for being manufactured in one piece with a temple 11 of a metal eyeglass frame 10, preferably made of precious metal, of the type referred to in technical jargon as "rimless".

[0027] Specifically, the frame comprises 10, referring to the example from Fig. 1, in a traditional manner, a bridge 13, which is positioned as a connection between two spectacle lenses 100 and is attached directly to them. Furthermore, the frame 10 advantageously comprises two fastening elements 12, each of which is attached directly to a corresponding spectacle lens 100 in a position opposite the bridge 13, i.e., outside the spectacle. In particular, each fastening element 12 is inserted into the interior of a slot provided on the lens 100 itself.

[0028] In particular, in the Fig. Figures 1 to 8 illustrate an embodiment in which the fastening element 12 comprises a fastening section 120, in particular a curved section, which is designed to be fastened in the slot of the glass 100, in particular behind it.

[0029] This will be discussed in the Fig. Figures 9 to 11 show a further embodiment in which the fastening element 12 comprises a front plate 121 from which the fastening section 120 advantageously extends. In this latter case, the fastening section 120 is advantageously designed to be fastened in the slot of the glass 100 in front of the latter, so that the front plate 121 covers the slot, resulting in a more pleasing aesthetic. Advantageously, the front plate 121 is provided with a decorative shape.

[0030] Furthermore, the frame 10 advantageously comprises two brackets 11, each of which is connected to the corresponding fastening element 12 via the hinge 1.

[0031] According to an alternative embodiment not shown, the frame 10 can also, in a traditional manner, comprise a central section with two ring-shaped segments (or “circles”) suitable for supporting the corresponding lenses, which are connected in the central part by the bridge. In this case, the temples are rotatably mounted by means of the hinges 1 on the sides of the central section and, more precisely, on two of its lateral segments facing the rear of the glasses, which are known in the industry as end pieces. Advantageously, the end piece therefore essentially corresponds to the fastening element 12 of a rimless frame.

[0032] In both cases described above, the temples 11 can functionally move between a folded position, in which they rest against the lenses 100 or the middle part of the frame 10, and an unfolded position, in which the temples 11 assume a position that is essentially perpendicular to the lenses 100 or the middle part, thanks to the hinges 1 mentioned above.

[0033] According to the invention, the hinge for eyeglasses comprises a first joint element 2, which is designed to be attached to a first component 11 of an eyeglass frame 10. The first joint element 2 comprises an elongated section 21, which is designed to be attached to the first component 11 of the eyeglass frame 10, and a pivot section 22, which is connected to the elongated section 21 and defines at least one opening 23 that extends along a pivot axis X.

[0034] In particular, the linkage section 22 comprises an inner surface 25 which advantageously limits the opening 23 mentioned above.

[0035] According to the in Fig. In the preferred embodiment shown in Figure 7, the linkage section 22 of the first joint element 2 is spiral-shaped and comprises at least one turn 24 that defines the opening 23 mentioned above.

[0036] Advantageously, the linkage section 22 comprises one to four turns 24, preferably one to three turns 24. Fig. Figure 7 shows, for example, a hinge 1 in which the linkage section 22 comprises two turns 24.

[0037] In particular, the direction of rotation of the coils 24 can be either clockwise or counterclockwise, depending on the arrangement of the hinge 1 in the frame 10 or on the side on which it is mounted. Furthermore, the direction of rotation of the coils 24 can be varied depending on aesthetic requirements.

[0038] Likewise, the direction of the turns can also be ascending or descending.

[0039] Specifically, the terms “direction of rotation” and “direction of travel” are to be understood as referring to the path defined by the course of the turns 24 around the pivot axis X or along the pivot axis X starting from the end of the pivot section 22 attached to the elongated section 21 of the first joint element 2.

[0040] Of course, the linkage section 22 can also have any other shape without thereby leaving the scope of protection of the invention.

[0041] The hinge 1 also includes a second joint element 3, which is intended to be attached to a second component 12 of the spectacle frame 10 and which includes a support section 31 designed to be attached to the second component 12 of the spectacle frame 10.

[0042] Furthermore, the hinge 1 includes a hinge pin 4 which is mounted on the support section 31 of the second joint element 3 and inserted into the opening 23 of the first joint element 2 to connect the first joint element 2 and the second joint element 3 rotatably about the pivot axis X.

[0043] In particular, the hinge pin 4 extends between a lower end 40, which is advantageously mechanically connected to the support section 31, and a free upper end 41.

[0044] Specifically, the hinge pin 4 is manufactured as a single piece with the second joint element 3, preferably with the support section 31 of the latter. For example, the second joint element 3 and the hinge pin 4 are manufactured as a single piece by investment casting or by plastic deformation through forging.

[0045] According to one embodiment, the hinge pin 4 is manufactured separately and connected to the support section 31, e.g. by welding, gluing or mortising.

[0046] Specifically, the lower end 40 of the hinge pin 4 is attached to the support section 31. For example, one end of the support section 31 is mortised into a cavity provided at the lower end 40 of the hinge pin 4.

[0047] Of course, without thereby leaving the scope of protection of this invention, the hinge pin 4 can be attached to the second joint element 3 in any other suitable way.

[0048] Advantageously, the hinge pin 4 comprises a side surface 42 that defines at least one guide groove 43, i.e., essentially a thread. Furthermore, the linkage section 22 advantageously engages with its own inner surface 25 in the aforementioned guide groove 43. If the linkage section 22 is helical, the turns 24 themselves engage in the guide groove 43.

[0049] This makes it more difficult to detach the linkage section 22 from the hinge pin 4, as this intervention prevents simple movement only along the linkage axis X.

[0050] Of course, without thereby leaving the scope of protection of the invention, the decoupling of the linkage section 22 can also be blocked or further hindered in other ways.

[0051] According to the idea underlying this invention, the hinge 1 also comprises a cover element 5 which is positioned to at least partially cover the pivot section 22 of the first joint element 2.

[0052] In this way, hinge 1 is more stable and resistant, as it is reinforced by the cover element 5.

[0053] Furthermore, this cover element 5 advantageously prevents dust and dirt from getting between the first joint element 2 and the hinge pin 4 and / or the second joint element 3 and hindering the rotation of the hinge 1.

[0054] Advantageously, the cover element 5 has the further benefit of making the hinge 1 more aesthetically pleasing, as the mechanism is concealed. Furthermore, the outer surface of the cover element 5 can be decorated with set gemstones, enamel, or any other decoration or decorative surface treatment. For this purpose, the cover element 5 is preferably made of a precious metal suitable for goldsmithing, for example, gold, silver, platinum, or their respective alloys.

[0055] Preferably, the first and second joint elements 2, 3 are also made of a metallic material, preferably a precious metal, for example gold, silver, platinum or their respective alloys. Of course, the hinge and / or any parts thereof can also be made of a base metal, e.g. nickel silver, steel or titanium, without thereby departing from the scope of the invention.

[0056] According to the invention, the cover element 5 is also provided with an opening 51 through which the elongated section 21 of the first hinge element 2 passes.

[0057] This advantageously prevents the cover element 5 from detaching from the coupling with the first joint element 2 of the hinge 1.

[0058] The cover element 5 is advantageously mounted on the first joint element 2 after the latter has been coupled to the second joint element 3 via the hinge pin 4 (in a manner known per se).

[0059] Operationally, assembly is carried out first by inserting the elongated section 21 of the first joint element 2 through the opening 51 of the cover element 5. The latter is then moved until it reaches the pivot section 22 and subsequently moved, for example rotated, until it is positioned as a cover for the pivot section 22. Advantageously, the cover element 5 is mechanically connected to the pivot section 22 of the first joint element 2 by means of a tenon joint.

[0060] Advantageously, the cover element 5 is connected to the linkage section 22 of the first joint element 2 in a rotationally fixed manner.

[0061] According to another embodiment, which is described in the Fig. As shown in Figures 9 to 11, the cover element 5 is mechanically connected to the second joint element 3 and / or to the hinge pin 4, in particular to the latter, by means of a screw 6 and is thus advantageously only indirectly connected to the pivot section 22 of the first joint element, in particular rotatably.

[0062] In this case, the cover element 5 is advantageously connected to the pivot section 22 of the second joint element 3 in a rotationally fixed manner.

[0063] According to all embodiments of the invention shown in the figures in the annex, the cover element 5 is advantageously of a concave shape and in particular defines a receptacle 52 in which the pivot section 22 of the first joint element 2 is at least partially arranged.

[0064] In detail, the recording 52 essentially corresponds to the dimensions of the linkage section 22 of the first joint element 2.

[0065] Advantageously, the cover element 5 comprises at least one stop section 53 designed to abut against the support section 31 of the second hinge element 3 in order to block, when in use, the rotation of the first hinge element 2 relative to the second hinge element 3, particularly when the hinge 1 is in the maximum extended position.

[0066] In this way it is advantageously possible to control the maximum rotation of hinge 1.

[0067] In detail, as particularly in the Fig. 2 and Fig. As can be seen in Figure 5, the cover element 5 is provided with a circumferential edge 54 which includes at least a first edge section 541 which is arranged in a first plane L1 which runs along the pivot axis X.

[0068] Furthermore, the circumferential edge 54 advantageously comprises at least a second edge section 542, which is arranged in a second plane L2 extending along the pivot axis X, which differs from the first plane L1.

[0069] In particular, the term "plane" refers to the center point of the projection of the first edge segment 541 or the second edge segment 542 onto the axis of rotation X of the hinge 1. Specifically, if the first edge segment 541 or the second edge segment 542 lies in a plane perpendicular to the axis of rotation X, its projection onto this axis of rotation X is itself a point. If, on the other hand, the first edge segment 541 or the second edge segment 542 does not lie in a plane perpendicular to the axis of rotation X, its projection onto this axis of rotation X is a segment, and its plane is defined as the center point of this segment.

[0070] More precisely, the first edge section 541 and the second edge section 542 are offset, i.e., not aligned with each other.

[0071] Advantageously, the circumferential edge 54 also includes an intermediate edge section 543, which runs as a connection between the first edge section 541 and the second edge section 542 and is arranged inclined in relation to the first edge section 541 and the second edge section 542.

[0072] Preferably, the stop section 53 of the cover element 5 comprises the intermediate edge section 543, with which it advantageously acts against the support section 31 of the second hinge element 3.

[0073] According to the preferred embodiment of the invention, which is for example in Fig. As shown in Figure 4, the cover element 5 comprises a cylindrical section 55 arranged around the pivot section 22 of the first joint element 2. In particular, the cylindrical section 55 extends with an axis that substantially coincides with the pivot axis X.

[0074] Advantageously, the opening 51 of the cover element 5 is at least partially located on the cylindrical section 55.

[0075] According to the preferred embodiment shown in the figures in the appendix, the opening 51 is essentially circular.

[0076] Naturally, the opening 51 can also have an elongated shape without thereby leaving the scope of protection of the present invention and, for example, extend from (or to) the circumferential edge 54 of the cover element 5. In the latter case, the opening 51 can therefore also be realized in the form of a slot or a notch on the cover element 5.

[0077] For example, according to the in the Fig. In the further embodiment of the invention shown in Figures 9 to 11, the opening 51 actually has an elongated shape and extends from the circumferential edge 54 of the cover element 5, in particular since it is provided in the form of a slot on the cover element 5.

[0078] As in the Fig. 9 and Fig. As can be seen from Figure 11, the opening 51 also advantageously comprises an insertion section 510, which is designed to insert the elongated section 21 of the first joint element 2 into the opening 51 by means of sliding. In particular, the insertion section 510 runs at least partially parallel to the pivot axis X.

[0079] Advantageously, the opening 51 also includes a pivot section 511 extending from the insertion section 510, in which the elongated section 21 is capable of sliding during the opening and closing of the hinge 1. In particular, the pivot section 511 extends circumferentially around the pivot axis X.

[0080] In this case, the stop section 53 of the cover element 5 is preferably designed to abut against the elongated section 21 of the first hinge element 2 in order to block, when in use, the rotation of the second hinge element 3 relative to the first hinge element 2, particularly when the hinge 1 is in a fully opened position.

[0081] Therefore, the stop area 53 of the cover element 5 advantageously comprises an end face of the rotating section 511.

[0082] Advantageously, the cover element 5 also includes a dome-shaped section 56 extending from the cylindrical section 55 to cover the upper end 41 of the hinge pin 4.

[0083] According to a further embodiment of the invention, which is described in the Fig. As shown in Figures 9 to 11, a through-opening (not shown) is provided on the dome-shaped section 56, through which at least the shaft of the screw 6 is inserted for attaching the cover element 5, in particular to the hinge pin 4.

[0084] Naturally, without thereby leaving the scope of protection of this invention, the cover element can have any shape and size, also depending on its secondary decorative purpose.

[0085] The present invention further relates to a spectacle frame 10 which advantageously comprises the hinge 1 described above.

[0086] The frame 10 is preferably, but not limited to, a frameless frame of the type described above and, for example, in Fig. 1 of the type shown.

[0087] According to the invention, the eyeglass frame 10 comprises a first component 11 and a second component 12. Preferably, according to the invention, the first component 11 corresponds to the second component 12. Fig. In the example shown, the first component 11 of the spectacle frame 10 is a temple, and the second component 12 of the spectacle frame 10 corresponds to an element for attaching it to a lens 100. In particular, the fastening element 12 for a lens 100 can be fitted directly into a lateral slot of the lens 100, or it can correspond to the end piece or the middle part of a traditional pair of spectacles.

[0088] The frame 10 also includes a hinge 1 for eyeglasses, which has the features described above and will therefore not be described in detail. The hinge 1 is positioned as a connection between the first and the second components 11, 12.

[0089] The following refers to the example in which the first component 11 of the eyeglass frame 10 consists, as mentioned, of a temple and the second component 12 of the fastening element of the frame 10, although embodiments in which the two components are reversed are also conceivable, and in particular embodiments in which the first joint element 2 is attached to the fastening element and the second joint element 3 to the temple, without thereby leaving the scope of protection of the present claim.

[0090] According to the invention, the elongated section 21 of the first joint element 2 is made from a single piece with the first component 11.

[0091] Furthermore, the support section 31 of the second joint element 3 is made from a single piece with the second component 12.

[0092] In this way it is possible to manufacture the entire frame 10 in a smaller number of steps, since the parts of the hinge 1 have already been manufactured in one piece and preferably with the same machining as the other parts of the frame 10.

[0093] In this case, the cover element 5 of the hinge 1 is operatively mounted onto the first joint element 2 by first guiding the entire bracket 11 through the opening 51 of the cover element 5 and then moving the latter until it reaches the pivot section 22. The subsequent steps are advantageously those described above.

[0094] Preferably, the first and second joint elements 2, 3, and advantageously also the brackets 11 and the fastening elements 12, are made of a preferably noble metal material, for example gold, silver, platinum, or their alloys. Of course, the frame 10 and / or any of its parts can also be made of a base metal material, for example nickel silver, steel, or titanium, without thereby departing from the scope of protection of the invention.

[0095] Of course, without thereby leaving the scope of protection of the present invention, at least a part of the first and second joint element 2, 3, the bracket 11, the fastening elements 12 and / or the cover element 5 can also be made of polymer material such as acetate.

[0096] The invention, as designed, therefore achieves the set objectives.
