Description

Title of the invention: Pair of glasses with locking pin and corresponding mounting method

[0001] The invention relates to a pair of glasses comprising a glasses element associated with a locking pin.

[0002] The invention also relates to a method of mounting an eyeglass element on such a pair of eyeglasses.

[0003] BACKGROUND OF THE INVENTION

[0004] An eyeglass frame generally comprises tenons to which temples are secured. The tenons comprise a first end portion fixed to a front part of the frame and a second opposite end portion, in the extension of which the temple extends.

[0005] The two end portions of the tenon can be articulated to each other by a hinge allowing the pivoting of the branch between a storage position in which the branch extends parallel to the glass and a use position in which the branch extends perpendicular to the glass. There are frames in which the branch is in one piece with the second end portion, the connection of the branch to the tenon being made at the hinge, and frames in which the branch is attached to the second portion.

[0006] Conventionally, the first end portion of the tenon is force-fitted into a housing in the front part of the frame in a direction of insertion perpendicular to the glass. In this way, the tenon is secured to the frame at one of the main faces of the frame.

[0007] The disadvantage is that it is then very difficult or even impossible to remove the tenon from the mount.

[0008] However, over time, glasses have gradually been stripped of their image as an optical prosthesis and have also taken on that of a fashion accessory in its own right, which is expected to adorn the wearer's face. At the same time, a very wide range of shapes and colors of glasses has developed.

[0009] Thus, the force-fitting of the tenon is no longer suitable for the need to quickly change the different elements of a pair of glasses if one of them is not suitable.

[0010] SUBJECT OF THE INVENTION

[0011] An aim of the invention is to propose a spectacle frame that is more easily removable and a corresponding method. Summary of the invention

[0012] To this end, according to the invention, there is provided a pair of glasses comprising a glasses element mounted on a frame of said pair of glasses or on a lens of said pair of glasses, the lens or the frame comprising at least one orifice provided with an insertion portion for the insertion of the element through the orifice, insertion portion extended by a narrowed portion for positioning the element in the lens or the frame, the pair of glasses further comprising a locking pin arranged in the orifice so as to extend at least through the insertion portion between the element on the one hand and the lens or the frame on the other hand to block the element in the pair of glasses.

[0013] Thus, to mount the eyeglass element, it is sufficient to introduce the element through the orifice at the level of the insertion portion and then to move the eyeglass element relative to the glass or the frame so that the eyeglass element advances into the narrowed portion of the orifice, namely the positioning portion. The locking pin is then brought back into the insertion portion so as to block the eyeglass element in the positioning portion.

[0014] To remove the eyeglass element, it is therefore sufficient to remove the locking pin and then move the eyeglass element relative to the lens or the frame so that the eyeglass element advances into the insertion portion. It is then possible to remove the eyeglass element from the frame or the lens.

[0015] The invention thus makes it possible to simply temporarily mount the eyeglass element on the frame or on the glass.

[0016] It therefore proves easy to separate the eyeglass element from the rest of the pair of eyeglasses, in particular because the eyeglass element is not force-fitted into said pair of eyeglasses.

[0017] This makes it easier to change an eyeglass element if it does not suit a user in order to fit another one to the frame or lens of the pair of eyeglasses in question.

[0018] Optionally, the eyeglass element is a tenon or a bridge.

[0019] Optionally, the orifice is shaped into a keyhole.

[0020] Optionally, the positioning portion is arranged further towards the outside of the lens or frame than the insertion portion.

[0021] Optionally, the locking pin at least partially covers a portion of the element protruding from a front face of the pair of glasses.

[0022] Optionally, the locking pin comprises at least one housing in which the portion of the element is received.

[0023] Optionally, the locking pin comprises at least one surface complementary to at least one surface of the eyeglass element.

[0024] Optionally the locking pin and the glasses element fit together less partly in each other.

[0025] Optionally, the eyeglass element comprises a finger shaped to at least partially match the shape of a lateral edge of the positioning portion.

[0026] Optionally, the element comprises a finger shaped to at least partially match the shape of a lateral edge of the positioning portion.

[0027] Optionally, the locking pin comprises an attachment part whose free end is at least partly beveled.

[0028] The invention also relates to a method of mounting an eyeglass element on a pair of eyeglasses as previously described, the method comprising the steps of: - arrange the glasses element through the introduction portion, - moving the eyeglass element along the hole so that it extends through the positioning portion, - place the locking pin at the level of the introduction portion.

[0048] With reference to [Fig.l], a pair of glasses 1 is visible comprising two lenses 2. The pair of glasses 1 is here without a frame, the two lenses 2 being connected to each other by at least one eyeglass element which will be described below.

[0049] It is thus possible to define a rear face and a front face for the pair of glasses 1 corresponding respectively to the face turned towards the face of the wearer of the pair of glasses and the opposite face.

[0050] The lenses 2 have an identical structure except that one is symmetrical to the other with respect to a median plane of the pair of glasses 1. In the remainder of the description, only one lens will be mentioned, referring indifferently to one or the other of the lenses.

[0051] Furthermore, the pair of glasses 1 comprises two lateral assemblies 3 connected respectively to the right lens and to the left lens of the pair of glasses. The terms “right” and “left” are to be understood in the frame of reference of the wearer of the pair of glasses when he wears said pair of glasses.

[0052] The lateral assemblies 3 have an identical structure except that one is symmetrical to the other with respect to a median plane of the pair of glasses. In the remainder of the description, only one assembly 3 will be mentioned, referring indifferently to one or the other lateral assembly.

[0053] Each side assembly 3 comprises a first part and a second part connected to each other. In the described embodiment, the first part is a tenon 4 and the second piece is a branch (not visible here).

[0054] The tenon 4 comprises a first part 5 and a second part (not visible here) connected by a hinge comprising an articulation axis integral with the first part 5 and thus allowing the pivoting of the branch between a storage position in which the branch extends parallel to the glass 2 and a use position in which the branch extends perpendicular to the glass 2.

[0055] An orifice 6 is provided in the glass 2 associated with the lateral assembly 3 considered. The orifice 6 is provided so as to be a through hole: the orifice 6 thus opens onto the front face and the rear face of the glass 2 (corresponding respectively to the front face of the pair of glasses 1 and to the rear face of the pair of glasses 1). Consequently, the orifice 6 is a through hole in the thickness of the glass 2 (thickness considered along a first axis Z).

[0056] The orifices 6 of the left and right lenses 2 are identical here except that one is symmetrical to the other with respect to a median plane of the pair of glasses 1. In the remainder of the description, only one orifice 6 will be mentioned, referring indifferently to one or the other orifice 6.

[0057] The orifice 6 comprises an introduction portion 7 which is extended by a narrowed portion forming a positioning portion 8. The orifice 6 thus extends longitudinally in the glass 2 along a second axis X (which is orthogonal to the first axis Z), the positioning portion 8 extending in the extension of the introduction portion 7 along said second axis X.

[0058] Typically, the orifice 6 is shaped so that the insertion portion 7 is located to the right of the positioning portion 8 for the left glass 2 and / or so that the insertion portion is located to the left of the positioning portion for the right glass 2.

[0059] The orifice 6 is for example shaped like a keyhole.

[0060] The orifice 6 is for example shaped so as to extend longitudinally along the second X axis narrowing towards an external edge of the lens 2 (left for the left lens 2 and right for the right lens 2) i.e. the edge of the lens 2. The terms “external” and “internal” must be understood in the user’s frame of reference when the pair of glasses 1 is worn by the user: “external” referring to the left and right sides of the pair of glasses 1 and “internal” referring to the side facing the other lens 2.

[0061] The introduction portion 7 is here of at least partially circular section (along a section plane of normal to the first axis Z) and / or the positioning portion is of at least partially oblong section (along a section plane of normal to the first axis Z) with a first lateral end of the positioning portion 8 opening into the introduction portion 7. Optionally the posi portion positioning portion 8 does not flare towards its second lateral end and / or does not narrow towards its second lateral end. Thus, preferably the positioning portion 8 has two longitudinal edges parallel to each other and to the second axis X.

[0062] The orifice 6 is for example provided in the upper part of the lens 2, the terms “upper” and “lower” being understood in the user's frame of reference when the pair of glasses 1 is worn by the user.

[0063] The orifice 6 is for example provided at the level of the external edge of the glass 2. Optionally, the orifice 6 is provided so that the positioning portion 8 is closer to the external edge than the introduction portion 7.

[0064] The orifice 6 is therefore provided on the external edge side of the glass 2 at the upper end of said external edge.

[0065] Optionally, when the pair of glasses 1 is worn, the orifice 6 extends substantially horizontally.

[0066] The first part 5 of the tenon 4 of the lateral assembly 3 also comprises means for fixing it to the rest of the pair of glasses 1, fixing means which thus form here the free end of the first part 5. For this purpose, said fixing means are shaped to be received in the orifice 6.

[0067] In particular, the free end 9 of the first part 5 of the tenon 4 of the lateral assembly 3 has an attachment zone 10 intended to come opposite the rear face of the glass 2. Preferably, the attachment zone 10 is shaped to match the shape of the rear face of the glass 2. Preferably, the attachment zone 10 is shaped to come to rest at least partly against the rear face of the glass 2. Typically, the attachment zone 10 comprises at least one face of curvature similar to that of the area of ​​the rear face of the glass 2 against which the attachment zone 10 is attached. In the present case, the attachment zone 10 is a single continuous flat or curved face.

[0068] Said attachment zone 10 is extended by a finger 11 for fixing to the glass 2, finger forming part of the aforementioned fixing means.

[0069] Said finger 11 thus extends from the attachment zone 10 in the opposite direction to the tenon 5. For example, the finger 11 extends rectilinearly from said attachment zone 10 along an axis D. The attachment zone has a larger surface area than a cross-section of the fixing finger (along a section plane normal to the axis D).

[0070] The finger 11 is here shaped so as to have a section (along a section plane normal to the axis D) which is at least partly rounded.

[0071] The finger 11 is shaped so that it can be housed in the positioning portion 8. Consequently, the section of the finger 11 has a shape which at least matches part that of the positioning portion 8. In the present case, the section of the finger 11 is oblong in shape.

[0072] The finger 11 has a length (along the axis D) substantially equal to that of the thickness of the glass 2 (along the first axis Z).

[0073] The finger 11 is extended by a plate 12. Said plate 12 extends in a plane with a normal axis D. According to a section plane with a normal axis D, the plate 12 has a section of a shape similar to that of the section of the finger 11. According to a section plane with a normal axis D, the plate 12 has a surface section greater than that of the finger 11. The plate 12 extends here parallel to the attachment zone 10.

[0074] In particular, the plate 12 is intended to come opposite the front face of the glass 2. Preferably, at least one main rear face of the plate 12 (the one connected to the finger 11) is shaped to match the shape of the front face of the glass 2. Preferably, said face is shaped to come to rest at least partly against the front face of the glass 2. Typically, said face has a curvature similar to that of the area of ​​the front face of the glass 2 against which the plate 12 is attached. In the present case, the plate 12 has a single continuous rear face, flat or curved.

[0075] The plate 12, the finger 11 and the first part 5 of the tenon 4 of the lateral assembly 3 form a unitary whole. The plate 12, the finger 11 and the first part 5 of the tenon 4 of the lateral assembly 3 are here made of a single piece.

[0076] Preferably, the finger 11 and the plate 12 both have a flat surface. Typically, the finger 11 and the plate 12 have the same flat surface 13 which thus extends rectilinearly along the finger 11 and the plate 12 along the axis D. For example, the flat surface 13 extends from the attachment zone 10 to a free main face of the plate 12 (opposite to that connected to the finger 11, i.e. the rear main face). The finger 11 and the plate 12 thus have the same flat face. Said flat face extends parallel to the axis D.

[0077] As more visible in [Fig.2b], when the free end 9 is in place in the pair of glasses 1, it extends through the orifice 6 so that the attachment zone 10 is in abutment against the rear face of the glass 2 and the rear main face of the plate 12 is in abutment against the front face of the glass 2. As for the finger 11, it extends into the orifice 6. Preferably, the finger 11 extends 6 into the orifice so that the axis D is parallel to the first axis Z.

[0078] More precisely, the finger 11 extends through the positioning portion 8 of the orifice 6. Even more precisely, the finger 11 extends through the positioning portion 8 of the orifice 6 so as to abut against the second lateral end of the positioning portion 8.

[0079] In this position, the flat 13 is turned towards the introduction portion 7. The rest of the finger 11 then matches the shape of the second lateral end of the positioning portion 8.

[0080] In order to hold the free end 9 in the glass 2, the pair of glasses 1 is equipped with a locking pin 14.

[0081] This comprises a cover 15 provided with an attachment part 16. As visible in [Fig.2c], when the pin 14 is in place in the pair of glasses 1, the attachment part 16 extends through the orifice 6 and the cover 15 extends to the front of the front face of the glass 2.

[0082] The cover 15 is here shaped into a plate. The cover 15 thus has a first main face 17 and a second main face 18 opposite the first main face 17, the attachment part 16 extending from the second main face 18. In the present case, the cover 15 is intended to come opposite the front face of the glass 2. Preferably, the second main face 18 is at least partially shaped to match the shape of the front face of the glass 2. Preferably, said second main face 18 is shaped to come to rest at least partly against the front face of the glass 2. Typically, said second main face 18 has at least one zone of curvature similar to that of the zone of the front face of the glass 2 against which it is attached. In the present case, the cover 15 comprises a single second main face 18 that is continuous, flat or curved.

[0083] The first main face 17 is thus visible to a person looking at the wearer of the pair of glasses 1.

[0084] At least the first main face 17 is shaped into a polygon. For example, the first main face 17 is shaped into a hexagon (regular or not) or a pentagon (regular or not) or a quadrilateral (regular or not). For example, the first main face 17 is shaped into a square or a rectangle. Optionally, the corners of the first main face 17 are rounded.

[0085] The first main face 17 is here flat or curved.

[0086] The first main face 17 here extends parallel to the second main face 18.

[0087] Preferably, the cover 15 has a flat 19. Typically, the flat 19 is formed in the thickness of the cover 15 (thickness considered along an axis C extending between the two main faces 17, 18 - optionally the axis C is a normal to said two main faces 17, 18): the flat 19 opens out at the second main face 18 so as to shorten it but does not open out at the first main face 17. Thus the flat 19 is invisible to a person looking straight at the wearer of the pair of glasses 1. The flat 19 extends rectilinearly along the cover 15 along an axis M (orthogonal to the axis C). The flat 19 therefore also opens out onto one of the lateral edges of the cover (the left edge for the pawn associated with glass 2 left and the right edge for the pawn associated with glass 2 right).

[0088] The attachment portion 16 extends rectilinearly from the second main face 18 along an axis T. Optionally, the axis T is a normal to the second main face 18 and / or is coincident with the axis C.

[0089] The attachment part 16 has a length (considered along the axis T) greater than that of the depth (along the first axis Z) of the orifice 6 so as to protrude from the rear face of the glass 2 when the pin 14 is in place in the orifice 6.

[0090] The attachment portion 16 here comprises at least one tab. For example, the attachment portion comprises at least two tabs 23. Each tab 23 is shaped in the form of an arc of a circle. Preferably, the tabs 23 are arranged concentrically so as to jointly form a tube extending along the axis T. Since the tabs 23 are radially spaced from one another, the tube is therefore discontinuous. Preferably, the tube formed by the tabs 23 has a curvature identical to that of the introduction portion 7. Preferably, the tube formed by the tabs 23 is shaped to fit a first lateral end of the introduction portion 7 (opposite that opening into the positioning portion 8).

[0091] The attachment part 16 also comprises a shim 24. The shim 24 is here of a length (considered along the axis T) smaller than that of the tabs 23. Preferably, the shim 24 is closer to the flat 19 of the cover 15 than the tabs 23. Preferably, the shim 24 is of a length less than the depth (considered along the first axis Z) of the orifice 6.

[0092] Optionally, a stud 25 extends rectilinearly along the axis T from the center of the tube drawn by the tabs 23 towards the outside of the pin 14. The stud 25 extends coaxially to the tube drawn by the tabs 23. The stud 25 extends over a length (considered along the axis T) less than that of the tabs 23 but greater than that of the shim 24.

[0093] The wedge 24 extends longitudinally along the stud 25 while being integral with said stud 25. The wedge 24 is thus in one piece with the stud 25. On the other hand, the tabs 23 extend at a distance from the stud 25.

[0094] In the present case, only the tabs 23 and the stud 25 of the attachment part 16 emerge from the orifice 6 through the rear face of the lens 2 when the pin 14 is in place in the pair of glasses.

[0095] Optionally, the shim 24 comprises a flat part 26 forming part of the flat 19 of the cover 15. The flat part 26 here extends rectilinearly beyond the cover 15. The height of the flat 19 of the cover 15 (considered along the axis C) is substantially equal to the thickness of the plate 12 (considered along the axis D).

[0096] Preferably, the free end of the attachment portion 16 is at least partially beveled. The free end of the attachment part 16 thus has at least one zone forming a plane inclined with respect to the axis T.

[0097] The beveling facilitates the insertion of the pin 14 into the orifice 6 once the free end is inserted into the orifice 6.

[0098] Typically the free end of at least one of the tabs 23 is beveled in the direction of the stud 25 and in the opposite direction of the cover 15 and / or the wedge 24 comprises a curved part 27 extending the flat part 24 to the stud 25 (curved part therefore extending in the direction of the stud 25 and in the opposite direction of the cover).

[0099] The attachment part 16 is integral with the cover 15 and is for example in one piece with the cover 15.

[0100] As more visible in [Fig.2c], when the pin 14 is in place in the pair of glasses 1, it extends through the orifice 6 so that the first main face 17 of the cover 14 is visible to a person looking at the wearer of the pair of glasses 1, the second main face 18 of the cover 14 is in abutment against the front face of the lens 2 and the attachment part 16 extends through the insertion portion 7 from the front face of the lens 2 until it partially protrudes from the rear face of the lens 2.

[0101] The tabs 23 are arranged opposite the first lateral end of the insertion portion 7. More precisely, the attachment part 16 extends through the insertion portion 7 so that the tabs 23 are in abutment against the first lateral end of the insertion portion 7.

[0102] In this position, the flat 19 is turned towards the positioning portion 8 (and towards the flat 13 of the finger 11) and is optionally attached to the flat 13 of the finger 11.

[0103] The remainder of the attachment portion 16 then takes the shape of the introduction portion 7.

[0104] The nipple 25 extends along the junction between the introduction portion 7 and the positioning portion 8. The nipple thus extends along the flat 13 of the finger 11.

[0105] Furthermore, the cover 15 covers the plate 12. A person looking straight at the wearer of the pair of glasses 1 therefore does not see the plate 12 since the cover 15 covers it. More precisely here, the plate 12 is housed in the flat 19 of the cover 15 so as to be covered at least by the first main face 17 for a person looking straight at the wearer of glasses 1.

[0106] Preferably, the flats 19 of the cover 15 and of the plate 12 are opposite each other or even are joined.

[0107] This makes it easier to place the pin 16.

[0108] Preferably, the pin 14 extends into the orifice 6 so that the axis M is parallel to the second axis X. Preferably, the pin 14 extends into the orifice 6 so that the C axis and / or the T axis is parallel to the first Z axis. Preferably, the pin 14 extends into the orifice 6 so that the C axis and / or the T axis is parallel to the D axis.

[0109] The method of mounting the free end 9 of the first part 5 of the tenon 4 will now be described.

[0110] With reference to [Fig.2a], during a first step, the free end 9 is inserted into the insertion portion 7 of the orifice 6 in a movement substantially perpendicular to the glass 2 from the rear face of the glass 2 towards the front face of the glass 2. The finger 11 extends here parallel to the first axis Z.

[0111] The free end 9 is then arranged so as to extend through the orifice 6 along the first axis Z, the attachment zone 10 resting against the rear face of the glass 2.

[0112] It is noted that this facilitates positioning for the user who pushes the free end 9 into the orifice 6 until the attachment zone 10 comes into abutment against the rear face of the glass 2.

[0113] In this position, the plate 12 emerges from the orifice 6 at the level of the front face of the glass 2.

[0114] It is also noted that the flat 13 is arranged in the orifice 6 so as to be turned towards the first lateral end of the introduction portion 7.

[0115] With reference to [Fig.2b], the free end 9 is slid into the orifice 6 until the finger 11 comes into abutment against the second lateral end of the positioning portion 8.

[0116] It is therefore understood that the orifice 6 acts as a groove for the free end 9 and thus facilitates its movement from the introduction portion 7 to the positioning portion 8.

[0117] In this position the plate 12 is in contact with the front face of the glass 2 and / or the attachment zone 10 is in contact with the rear face of the glass 2.

[0118] This limits a relative displacement of the free end 9 of the tenon (and therefore of the branch) with respect to the glass 2 in particular along the first axis Z.

[0119] As indicated previously, the section of the finger 11 has a shape matching at least in part that of the positioning portion 8. In the present case, as more visible in [Fig. 10], the section of the finger 11 is oblong in shape so that it has two flats (A and B) facing respectively flat parts of the orifice 6.

[0120] This limits a rotation of the tenon 4 in the orifice 6 along the first axis Z.

[0121] Furthermore, the finger 11 bears against the longitudinal ends and the second lateral end of the positioning portion 8.

[0122] This limits a relative displacement of the free end 9 (and therefore of the branch) with respect to the glass 2 in particular along the second axis X and a third axis Y (orthogonal to the first axis Z and to the second axis X). With reference to [Fig.2c], we then come to position the pin 14 in the introduction portion 7 in a movement substantially perpendicular to the glass 2 from the front face of the glass 2 towards the rear face of the glass 2.

[0123] The pin 14 is then arranged so as to extend through the orifice 6 along the first axis Z, the second main face 18 of the cover 15 resting against the front face of the glass 2.

[0124] It is noted that this facilitates positioning for the user who pushes the pin 14 into the orifice 6 until the second main face 18 of its cover 15 comes into abutment against the front face of the glass 2.

[0125] This cooperation of the pin 14 with the orifice 6 on the one hand and the free end 9 (and therefore of the branch) on the other hand makes it possible to limit a displacement of said free end 9 in particular along the second axis X.

[0126] In particular, the cooperation between the flat 13 and the flat part 26 limits a rotation of the pin 14 around its axis T in the orifice 6.

[0127] The assembly of the free end 9 is thus simple and rapid.

[0128] Furthermore, this assembly is reversible since it is sufficient to remove the pin 14 and move the free end 9 from the positioning portion 8 to the insertion portion 7 to remove it from the pair of glasses 1.

[0129] Referring again to [Fig.l], it is understood that what has been said above for the tenon (and therefore the branch), is just as applicable to another element of glasses such as the bridge 20, that is to say the part resting on the user's nose. It is noted that in the present case, the bridge 20 is the element of glasses 1 which also makes it possible to secure the two lenses together.

[0130] In this way, as illustrated in [Fig.3a], during a first step, the end of the bridge 20 is inserted into the introduction portion of an orifice 21 (identical in the present case to that provided for the tenon and oriented in the same way) according to a movement substantially perpendicular to the glass 2 from the rear face of the glass 2 towards the front face of the glass 2.

[0131] With reference to [Fig.3b], the end of the bridge 20 is slid into the orifice 21 until the end of the bridge comes into abutment against the lateral end of the positioning portion of the orifice.

[0132] With reference to [Fig.3c], the pin 22 is then positioned in the insertion portion of the orifice 21 in a movement substantially perpendicular to the glass 2 from the front face of the glass 2 towards the rear face of the glass 2.

[0133] The cooperation of the end of the bridge 20 with the pin 14 and the orifice 21 thus makes it possible to lock the bridge 20 in position in the pair of glasses.

[0134] Of course, the invention is not limited to the embodiment described but encompasses any variant falling within the scope of the invention as defined by the re- sales.

[0135] In particular, although here the pair of glasses is without a frame, the pair of glasses may include a frame. The eyeglass element may then be worn either by the lens or by the frame. If the eyeglass element is worn by the frame, the orifice associated with the eyeglass element will then be provided in the frame directly so as to pass through said frame. Everything that has been said previously for mounting the element directly on the lens is thus applicable to the embodiment where the element is mounted directly on the frame. [Fig.7] thus illustrates such a pair of glasses for which the branch is mounted on the frame by means of a locking pin.

[0136] Whether the pair of glasses has a frame or does not have a frame, the pair of glasses may have two lenses or a single lens. In both cases, the eyeglass element may be worn by the lens or by the frame (if the pair of glasses has one).

[0137] If it is the frame that carries the element, the hole will then be made in the latter and no longer in the glass directly. [Fig.7] illustrates such a pair of glasses.

[0138] The orifice may take a shape other than that indicated. For example, the introduction portion may be shaped into an oval, rectangular, oblong section, etc., and / or the positioning portion may be shaped into an oval, rectangular, oblong section, etc.

[0139] The orientation of the orifice may also be different from what has been indicated. For example, the orifice may extend (whether considering the mounting of a tenon or a bridge) so that the insertion portion is to the right of the positioning portion or it may extend so that the insertion portion is to the left of the positioning portion. [Fig. 8] thus illustrates two possibilities of orientation of the orifice. For example, the orifice may extend substantially vertically (when the pair of glasses is worn by the user) instead of extending substantially horizontally as has been described. Here again, the insertion portion may extend above the positioning portion or below.The orifice may extend substantially obliquely (when the pair of glasses is worn by the user), the insertion portion being able to be closer to an external edge of the pair of glasses than the positioning portion or further away.

[0140] Although here the cache has a cross-section in a polygon, the section may be of another shape and for example oblong or circular. If the section is in a polygon, it may still have a shape other than a quadrilateral and be for example shaped into a triangle, a hexagon, etc. Regardless of the shape of the cross-section, it may have at least one rounded angle.

[0141] Although here the pin comprises a cover completely covering the free end of the eyeglass element on the front face side of the glass, the cover may be shaped to only partially cover said free end (front face side of the glass) or may be shaped to not cover said free end (front face side of the glass).

[0142] The attachment part may be shaped differently from what has been indicated. For example, the attachment part may comprise a rod extended by a foldable return so as to extend either in the extension of the rod or obliquely or perpendicularly to the rod, the rod being intended to remain in the orifice to block the free end of the eyeglass element in position and the return coming to bear against the rear face of the glass to secure the assembly.

[0143] Although here the eyeglass element is mounted by the rear face of the glass (and the associated pin by the front face of the glass), the assembly can be reversed. The eyeglass element will thus be introduced into the orifice from the front face of the glass towards the rear face of the glass and the pin will be introduced into the orifice from the rear face of the glass towards the front face of the glass. [Fig.9] thus illustrates the two assembly possibilities which have just been described.

[0144] The tenon and / or the branch and / or the bridge may be made of different materials such as synthetic material, plastic material, metal material, etc.

[0145] In the same way the frame, if it exists, could be in different materials such as synthetic material, plastic material, metallic material, etc.

[0146] The frame, if it exists, may externally surround the lens(es) or only partially surround the lens(es).

[0147] The eyeglass frame may have only one lens.

[0148] The eyeglass element may be a bridge, a branch, a tenon, a lateral assembly, etc.

[0149] The pin will be held in place in the orifice without additional fixing means and for example either by being snapped into it or by simple adjustment. Alternatively or additionally, the pin may be held in place in the orifice via additional fixing means such as for example a screw-nut assembly. Alternatively or additionally, a free end of the pin may be shaped to cooperate with an element preventing the pin from being removed from the orifice. For example, the free end of the pin may be threaded so as to cooperate with a nut (for example introduced through the rear face of the glass) mounted on the pin once it is in place in the orifice - the nut then preventing the pin from being removed from the orifice. It is understood that in all cases, the eyeglass element and the pin are mounted on the pair of eyeglasses in a removable manner.

[0150] Although here the pin and the eyeglass element have facing flats, the pin and the eyeglass element may have other facing surfaces. The pin and the eyeglass element may thus comprise complementary surfaces so that the pin and the eyeglass element fit together at least partially when the pin and the eyeglass element are in place in the orifice. [Fig. 12] thus proposes an arrangement in which the pin has a section (of section plane the axis T) which is externally circular and the portion facing the eyeglass element comprises a chute for housing said pin. [Fig. 13] thus proposes an arrangement in which the pin has a section (of section plane the axis T) having a chute in which is housed a rounded portion facing the eyeglass element. The eyeglass element may thus have a section at the orifice which is entirely oblong.

[0151] The pin and the eyeglass element may not have complementary surfaces. The pin may thus be shaped so as to be free to rotate around its axis T. For example, the pin may have a section (of section plane the axis T) which is externally circular. The pin may thus be without a shim and / or the shim may be without a flat part and / or the pin may be without the flat part.

[0152] Although here the orifice and the eyeglass element have one or more complementary surfaces, the orifice and the eyeglass element may have other facing surfaces. For example, as seen in [Fig. 11], the element may be shaped so that its section at the orifice (section plane the Z axis) has a single zone matching that of the orifice. For example, said zone may be a flat A matching the corresponding flat part of the orifice. The zone opposite the flat may for example be in an arc of a circle. It will be understood that for the comfort of the person wearing the pair of glasses, care will be taken to ensure that the eyeglass element cannot rotate freely in the orifice around the Z axis once the pin is in place.

[0153] If the eyeglass element is a branch, said branch may be in one piece with the second part of the tenon, the connection of the branch to the tenon being made at the hinge. Such a pair of glasses is illustrated in [Fig.5]. Alternatively, the branch will be attached to the second part. Alternatively, the branch and the tenon will be in one piece. There will then be no hinge allowing the branch to be folded down. Alternatively, said part jointly forming the branch and the tenon will be sufficiently flexible to intrinsically ensure the hinge function. If a hinge function is present in the pair of glasses, the branch will then be able to fold down in a rotational movement about an axis or will be able to fold down in another movement such as, for example, a movement combining at least two rotations or a rotation and a translation.The pair of glasses may thus have a hinge such as, for example, that described by the present applicant in application FR 2 844 062.
