Glasses with locking pin and mounting method for it

Description

[0001] The invention relates to a pair of glasses comprising a lens element associated with a locking pin. The invention also relates to a method for mounting a lens element onto such a pair of glasses. BACKGROUND OF THE INVENTION

[0002] A pair of glasses typically has tenons to which the temples are attached. The tenons have a first end portion fixed to a front part of the frame and a second end portion opposite, in the extension of which the temple extends.

[0003] The two end sections of the tenon can be hinged together, allowing the temple to pivot between a storage position, where the temple extends parallel to the lens, and a wearing position, where the temple extends perpendicular to the lens. Some frames have the temple as a single piece with the second end section, the connection between the temple and the tenon occurring at the hinge, while others have the temple attached to the second end section.

[0004] Typically, the first end portion of the tenon is press-fitted into a recess in the front part of the frame, with the insertion perpendicular to the lens. In this way, the tenon is secured to the frame at one of its main faces.

[0005] The drawback is that it then becomes very difficult or even impossible to remove the tenon from the mount.

[0006] Over time, eyeglasses have gradually shed their image as merely optical aids and have also become a fashion accessory in their own right, expected to enhance the wearer's appearance. This has led to a significant increase in the variety of eyeglass shapes and colors available.

[0007] Thus, the tenon-force assembly 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.

[0008] A prior art document showing a frameless spectacle mechanism in which the lenses can be held firmly in place without fluctuation through a simple structure is document US5847800A. SUBJECT OF THE INVENTION

[0009] One aim of the invention is to provide a more easily disassembled eyeglass frame and a corresponding method. SUMMARY OF THE INVENTION

[0010] For this purpose, according to the invention, a pair of glasses is provided comprising a lens element mounted on a frame of said pair of glasses or on a lens of said pair of glasses, the lens or frame having at least one orifice provided with an introduction portion for the introduction of the element through the orifice, the introduction portion being extended by a narrowed portion for positioning the element in the lens or frame, the pair of glasses further comprising a locking pin arranged in the orifice so as to extend at least through the introduction portion between the element on one side and the lens or frame on the other side to lock the element in the pair of glasses.

[0011] Thus, to mount the eyeglass element, simply insert it through the opening at the insertion point, then move the element relative to the lens or frame so that it advances into the narrower portion of the opening, namely the positioning portion. Then, return the locking pin to the insertion point to secure the eyeglass element in the positioning portion.

[0012] To remove the lens element, simply remove the locking pin and then move the lens element relative to the lens or frame so that it advances into the insertion portion. The lens element can then be removed from the frame or lens.

[0013] The invention thus makes it easy to temporarily mount the eyeglass element onto the frame or onto the lens.

[0014] It is therefore easy to separate the eyeglass element from the rest of the pair of glasses, in particular because the eyeglass element is not forced into the said pair of glasses.

[0015] This makes it easier to change a component of glasses if it was not suitable for a user, in order to fit another one onto the frame or lens of the pair of glasses in question.

[0016] Optionally, the eyepiece element is a tenon or a bridge.

[0017] Optionally, the opening is shaped into a keyhole.

[0018] Optionally, the positioning portion is arranged further out on the lens or frame than the introduction portion.

[0019] Optionally, the locking pin covers at least part of a portion of the element protruding from one front face of the pair of glasses.

[0020] Optionally, the locking pin includes at least one recess into which the portion of the element is received. Optionally, the locking pin includes at least one surface that is complementary to at least one surface of the eyeglass element.

[0021] Optionally, the locking pin and the eyepiece element fit at least partially into each other. Optionally, the eyepiece element has a finger shaped to fit at least partially the shape of a lateral edge of the positioning portion.

[0022] Optionally the element includes a finger shaped to at least partially fit the shape of a lateral edge of the positioning portion.

[0023] Optionally the locking pin includes an attachment part whose free end is at least partially beveled.

[0024] The opening is designed so that it opens onto a front face of the lens or frame and onto a back face of the lens or frame.

[0025] Optionally, the opening is only accessible at the front and back surfaces. In this case, the opening is not accessible at either of the outer edges of the lens or frame.

[0026] The locking pin secures the glasses element in the positioning portion.

[0027] The lens element rests against at least one edge of the opening and optionally against at least one edge of the positioning portion. The invention also relates to a method for mounting a lens element onto a pair of glasses as described above, the method comprising the steps of: Arrange the eyeglass element through the infeed portion, move the eyeglass element along the orifice so that it extends through the positioning portion, place the locking pin at the infeed portion.

[0028] Other features and advantages of the invention will become apparent from the description that follows. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0030] With reference to the figure 1 , a pair of glasses 1 is visible, comprising two lenses 2. The pair of glasses 1 is here frameless, the two lenses 2 being connected to each other by at least one element of glasses which will be described below.

[0031] We can thus define a back face and a front face to 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.

[0032] The lenses 2 have an identical structure except that one is the symmetrical image of the other with respect to a median plane of the pair of glasses 1. In the following description, only one lens will be mentioned, referring indifferently to either of the lenses.

[0033] Furthermore, the pair of glasses 1 comprises two lateral assemblies 3 connected respectively to the right and left lenses of the glasses. The terms "right" and "left" are to be understood in the frame of reference of the wearer of the glasses when wearing said pair of glasses.

[0034] The three lateral assemblies have an identical structure except that one is the mirror image of the other with respect to a median plane of the glasses. In the following description, only one of the three lateral assemblies will be referred to, meaning it can refer to either of them.

[0035] Each lateral assembly 3 comprises a first piece and a second piece connected to each other. In the described embodiment, the first piece is a tenon 4 and the second piece is a branch (not visible here).

[0036] The tenon 4 comprises a first part 5 and a second part (not visible here) connected by a hinge having an articulation axis fixed to the first part 5 and thus allowing the branch to pivot between a storage position in which the branch extends parallel to the lens 2 and a use position in which the branch extends perpendicular to the lens 2.

[0037] An opening 6 is provided in the lens 2 associated with the lateral assembly 3 under consideration. The opening 6 is designed to be a through hole: the opening 6 thus opens onto the front and rear faces of the lens 2 (corresponding respectively to the front and rear faces of the pair of glasses 1). Consequently, the opening 6 passes through the thickness of the lens 2 (the thickness considered along a first axis Z). The openings 6 of the left and right lenses 2 are identical here except that one is the reflection of the other with respect to a median plane of the pair of glasses 1. In the remainder of the description, only one opening 6 will be mentioned, referring interchangeably to either opening 6.

[0038] The orifice 6 has 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 continuation of the introduction portion 7 along said second axis X.

[0039] Typically, the orifice 6 is shaped so that the introduction portion 7 is to the right of the positioning portion 8 for the left lens 2 and / or so that the introduction portion is to the left of the positioning portion for the right lens 2.

[0040] The opening 6 is, for example, shaped like a keyhole. The opening 6 is, for example, shaped so as to extend longitudinally along the second axis X, narrowing towards an outer edge of lens 2 (left for left lens 2 and right for right lens 2), i.e., the edge of lens 2. The terms "outer" and "inner" should be understood in the user's frame of reference when the pair of glasses 1 is worn by the user: "outer" referring to the left and right sides of the pair of glasses 1 and "inner" referring to the side facing the other lens 2.

[0041] The infeed portion 7 is at least partially circular in cross-section (along a cross-sectional plane normal to the first Z-axis) and / or the positioning portion is at least partially oblong in cross-section (along a cross-sectional plane normal to the first Z-axis), with the first lateral end of the positioning portion 8 opening into the infeed portion 7. Optionally, the positioning portion 8 does not flare out towards its second lateral end and / or does not narrow towards its second lateral end. Preferably, the positioning portion 8 has two longitudinal edges that are parallel to each other and to the second X-axis.

[0042] The opening 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.

[0043] The orifice 6 is for example provided at the outer edge of the glass 2. Optionally the orifice 6 is provided so that the positioning portion 8 is closer to the outer edge than the introduction portion 7.

[0044] The opening 6 is therefore provided on the outer edge side of the glass 2 at the upper end of said outer edge.

[0045] Optionally, when the pair of glasses 1 is worn, the opening 6 extends substantially horizontally.

[0046] Note that the opening 6 does not open onto any surface other than the front and rear faces of the glasses 1. In particular, the opening 6 does not open onto an outer edge of the lens 2. The cross-section of the opening 6 (perpendicular to the first Z-axis) is thus closed. Specifically, neither the positioning portion 8 nor the insertion portion 7 opens onto an outer edge of the lens 2.

[0047] The first part 5 of the tenon 4 of the lateral assembly 3 also includes means for its attachment to the rest of the pair of glasses 1, attachment means which thus form here the free end of the first part 5. For this purpose, said attachment means are shaped to be received in the orifice 6.

[0048] 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 face the rear face of the lens 2. Preferably, the attachment zone 10 is shaped to conform to the shape of the rear face of the lens 2. Preferably, the attachment zone 10 is shaped to rest at least partially against the rear face of the lens 2. Typically, the attachment zone 10 has at least one face with a curvature similar to that of the area of ​​the rear face of the lens 2 against which the attachment zone 10 is pressed. In this case, the attachment zone 10 is a single continuous flat or curved face.

[0049] The said attachment zone 10 is extended by a finger 11 for fixing to the glass 2, the finger being part of the aforementioned fixing means.

[0050] The said finger 11 thus extends from the attachment zone 10 in the opposite direction to the tenon 5. For example, the finger 11 extends straight from the 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).

[0051] Finger 11 is here shaped so as to present a section (along a section plane normal to axis D) that is at least partly rounded.

[0052] Finger 11 is shaped to fit into positioning portion 8. As a result, the cross-section of finger 11 has a shape that at least partially matches that of positioning portion 8. In this case, the cross-section of finger 11 is oblong in shape.

[0053] Finger 11 has a length (along axis D) that is approximately equal to the thickness of glass 2 (along the first axis Z).

[0054] The finger 11 is extended by a plate 12. Said plate 12 extends in a plane normal to the axis D. Along a cross-sectional plane normal to the axis D, the plate 12 has a cross-section similar in shape to that of the finger 11. Along a cross-sectional plane normal to the axis D, the plate 12 has a cross-sectional area greater than that of the finger 11. The plate 12 extends parallel to the attachment area 10.

[0055] In particular, the plate 12 is designed to face 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 conform to the shape of the front face of the glass 2. Preferably, this face is shaped to rest at least partially against the front face of the glass 2. Typically, this 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 this case, the plate 12 has a single continuous rear face, either flat or curved.

[0056] The plate 12, the finger 11, and the first part 5 of the tenon 4 of the lateral assembly 3 form a single unit. The plate 12, the finger 11, and the first part 5 of the tenon 4 of the lateral assembly 3 are here in one piece.

[0057] Preferably, both the finger 11 and the plate 12 have a flat surface. Typically, the finger 11 and the plate 12 share the same flat surface 13, which extends straight along the finger 11 and the plate 12 along axis D. For example, the flat surface 13 extends from the attachment area 10 to a free principal face of the plate 12 (opposite to the face connected to the finger 11, i.e., the rear principal face). The finger 11 and the plate 12 thus share the same flat face. This flat face extends parallel to axis D.

[0058] As more visible to the figure 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 area 10 is in contact with the rear face of the lens 2 and the main rear face of the tray 12 is in contact with the front face of the lens 2. As for the finger 11, it extends into the orifice 6. Preferably, the finger 11 extends into the orifice 6 so that the axis D is parallel to the first axis Z.

[0059] More specifically, the finger 11 extends through the positioning portion 8 of the orifice 6. More specifically still, the finger 11 extends through the positioning portion 8 of the orifice 6 so as to be abutted against the second lateral end of the positioning portion 8.

[0060] In this position, the flat 13 is turned towards the introduction portion 7. The rest of the finger 11 then conforms to the shape of the second lateral end of the positioning portion 8.

[0061] In order to lock the free end 9 in the glass 2, the pair of glasses 1 is equipped with a locking pin 14.

[0062] This includes a cover 15 with an attachment part 16. As visible at the figure 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 lens 2.

[0063] The cover 15 is here shaped as 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 portion 16 extending from the second main face 18. In this case, the cover 15 is intended to be positioned opposite the front face of the lens 2. Preferably, the second main face 18 is at least partially shaped to conform to the shape of the front face of the lens 2. Preferably, said second main face 18 is shaped to rest at least partially against the front face of the lens 2. Typically, said second main face 18 has at least one area of ​​curvature similar to that of the area of ​​the front face of the lens 2 against which it is attached. In this case, the cover 15 comprises a single, continuous, flat or curved second main face 18.

[0064] The first main face 17 is thus visible to a person looking at the wearer of the pair of glasses 1.

[0065] At least the first principal face 17 is shaped into a polygon. For example, the first principal face 17 is shaped into a hexagon (regular or irregular), a pentagon (regular or irregular), or a quadrilateral (regular or irregular). Alternatively, the first principal face 17 is shaped into a square or a rectangle. Optionally, the corners of the first principal face 17 are rounded.

[0066] The first main face 17 is here flat or curved.

[0067] The first main face 17 extends here parallel to the second main face 18.

[0068] 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 the two main faces 17, 18): the flat 19 is open at the level of the second main face 18 so as to shorten it but is not open at the level of the first main face 17.

[0069] Thus, the flat surface 19 is invisible to a person looking directly at the wearer of the glasses 1. The flat surface 19 extends straight along the cover 15 along an axis M (orthogonal to axis C). The flat surface 19 therefore also opens onto one of the lateral edges of the cover (the left edge for the pin associated with the left lens 2 and the right edge for the pin associated with the right lens 2).

[0070] The attachment part 16 extends straight out 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 coincides with the axis C.

[0071] The attachment part 16 is of a length (considered along the T axis) greater than that of the depth (along the first Z axis) 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.

[0072] The attachment portion 16 here includes at least one tab. For example, the attachment portion includes at least two tabs 23. Each tab 23 is shaped like 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 each other, the tube is therefore discontinuous. Preferably, the tube formed by the tabs 23 has a curvature identical to that of the inlet portion 7. Preferably, the tube formed by the tabs 23 is shaped to fit a first lateral end of the inlet portion 7 (opposite to the end opening into the positioning portion 8).

[0073] The attachment part 16 also includes a shim 24. The shim 24 is here of shorter length (considered along the T axis) than 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 shorter length than the depth (considered along the first Z axis) of the orifice 6.

[0074] Optionally, a nipple 25 extends straight along the axis T from the center of the tube drawn by the tabs 23 to the outside of the pin 14. The nipple 25 extends coaxially to the tube drawn by the tabs 23. The nipple 25 extends over a length (considered along the axis T) less than that of the tabs 23 but greater than that of the wedge 24.

[0075] The wedge 24 extends longitudinally along the nipple 25, being integral with said nipple 25. The wedge 24 is thus a single unit with the nipple 25. In contrast, the tabs 23 extend at a distance from the nipple 25.

[0076] In the present case, only the tabs 23 and the nipple 25 of the attachment part 16 protrude from the opening 6 through the rear face of the lens 2 when the pin 14 is in place in the pair of glasses.

[0077] Optionally the wedge 24 has a flat part 26 forming part of the flat 19 of the cover 15. The flat part 26 extends straight beyond the cover 15. The height of the flat 19 of the cover 15 (considered along axis C) is substantially equal to the thickness of the plate 12 (considered along axis D).

[0078] Preferably, the free end of the attachment part 16 is at least partially beveled. The free end of the attachment part 16 thus has at least one area forming a plane inclined with respect to the axis T.

[0079] The beveling facilitates the insertion of the pin 14 into the hole 6 once the free end is inserted into the hole 6.

[0080] Typically the free end of at least one of the tabs 23 is beveled in the direction of the nipple 25 and in the opposite direction of the cover 15 and / or the wedge 24 has a curved part 27 extending the flat part 24 to the nipple 25 (curved part therefore extending in the direction of the nipple 25 and in the opposite direction of the cover).

[0081] The attachment part 16 is integral with the cover 15 and is, for example, one piece with the cover 15.

[0082] As more visible to the figure 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, that the second main face 18 of the cover 14 is in contact with the front face of the lens 2 and that the attachment part 16 extends through the introduction portion 7 from the front face of the lens 2 until it partially protrudes from the rear face of the lens 2.

[0083] The tabs 23 are arranged opposite the first lateral end of the inlet portion 7. More precisely, the attachment part 16 extends through the inlet portion 7 so that the tabs 23 are abutted against the first lateral end of the inlet portion 7.

[0084] In this position, the flat 19 is turned towards the positioning portion 8 (and towards the flat 13 of finger 11) and is optionally attached to the flat 13 of finger 11.

[0085] The remainder of the attachment portion 16 then conforms to the shape of the introduction portion 7.

[0086] 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.

[0087] Furthermore, the cover 15 covers the plate 12. Therefore, a person looking directly at the wearer of the glasses 1 cannot see the plate 12 because the cover 15 covers it. More precisely, the plate 12 is housed in the flat surface 19 of the cover 15 so that it is covered at least by the first main face 17 for a person looking directly at the wearer of glasses 1.

[0088] Preferably, the flat surfaces 19 of the cover 15 and the plate 12 are opposite each other or even adjacent.

[0089] This makes it easier to set up pawn 16.

[0090] Preferably, pin 14 extends into hole 6 such that axis M is parallel to the second X-axis. Preferably, pin 14 extends into hole 6 such that axis C and / or axis T is parallel to the first Z-axis. Preferably, pin 14 extends into hole 6 such that axis C and / or axis T is parallel to axis D.

[0091] The assembly process for the free end 9 of the first part 5 of the tenon 4 will now be described.

[0092] With reference to the figure 2a , in a first step, the free end 9 is inserted into the introduction portion 7 of the orifice 6 with 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.

[0093] The free end 9 is then arranged so as to extend through the orifice 6 along the first axis Z, the attachment area 10 resting against the rear face of the glass 2.

[0094] Note that this facilitates positioning for the user who pushes the free end 9 into the orifice 6 until the attachment area 10 comes to rest against the back face of the glass 2.

[0095] In this position, the plate 12 protrudes from the orifice 6 at the level of the front face of the glass 2.

[0096] 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.

[0097] With reference to the figure 2b , we slide the free end 9 into the orifice 6 until the finger 11 comes to rest against the second lateral end of the positioning portion 8.

[0098] 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.

[0099] In this position the plate 12 is resting against the front face of the glass 2 and / or the attachment area 10 is resting against the rear face of the glass 2.

[0100] 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.

[0101] As previously stated, the section of finger 11 has a shape that at least partially matches that of the positioning portion 8. In the present case, as more visible at the figure 10 , the section of finger 11 is oblong in shape so that it has two flats (A and B) opposite respectively flat parts of the orifice 6.

[0102] This limits the rotation of tenon 4 in orifice 6 along the first Z axis.

[0103] In addition, finger 11 is supported against the longitudinal ends and the second lateral end of the positioning portion 8.

[0104] This limits a relative displacement of the free end 9 (and therefore of the branch) with respect to the lens 2 in particular along the second axis X and a third axis Y (orthogonal to the first axis Z and the second axis X).

[0105] With reference to the figure 2c , we then position the pin 14 in the introduction portion 7 according to a movement substantially perpendicular to the glass 2 from the front face of the glass 2 towards the back face of the glass 2.

[0106] 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.

[0107] Note 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 to rest against the front face of the glass 2.

[0108] 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.

[0109] 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.

[0110] In this position, the pin 14 and the free end 9 are both in direct contact with at least a portion of the orifice 6. In particular, the pin 14 is in direct contact (i.e. without an intermediate piece) with at least a portion of the introduction portion 7 and the free end 9 is in direct contact (i.e. without an intermediate piece) with at least a portion of the positioning portion 8. The pin 14 allows in particular the free end 9 to be pressed against at least one edge defining the orifice 6 and in the present case to be pressed the free end 9 against the glass.

[0111] Preferably, at least a portion of the pin 14 is shaped to match the shape of a portion opposite the insertion portion 7, and at least a portion of the free end 9 is shaped to match the shape of a portion opposite the positioning portion 8. It is therefore understood that the pin 14 locks the free end 9 in the positioning portion 8. The function of the pin 14 is thus to lock the free end 9 in the orifice 6, but not to position the pin 14 in the orifice 6. Indeed, as can be seen in the figure 2b The free end 9 positions itself in the positioning portion 8 without needing the pawn 14 to support it. Similarly, the pawn 14 positions itself in the positioning portion 8 without the free end 9 needing to support it.

[0112] It is therefore understood that the free end 9 and the pin 14 remain independently of each other in the orifice 6. The cooperation of these two parts only allows them to be locked in position in the orifice 6.

[0113] The assembly of the free end 9 is therefore simple and quick.

[0114] In addition, this assembly is reversible since it is enough 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.

[0115] With further reference to the figure 1 It is understood that what was said above regarding the tenon (and therefore the temple) is equally applicable to another eyeglass component such as the bridge 20, that is, the part resting on the user's nose. It should be noted that in this case, the bridge 20 is the eyeglass component 1 that also serves to secure the two lenses together.

[0116] Thus, as illustrated in the figure 3a , in a first step, the end of the bridge 20 is inserted into the insertion portion of an orifice 21 (identical in this case to that provided for the tenon and oriented in the same way) 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.

[0117] With reference to the figure 3b , the end of the bridge 20 is slid into the orifice 21 until the end of the bridge comes to rest against the lateral end of the positioning portion of the orifice.

[0118] With reference to the figure 3c , we then position the pin 22 in the introduction portion of the orifice 21 with a movement substantially perpendicular to the glass 2 from the front face of the glass 2 towards the rear face of the glass 2.

[0119] 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.

[0120] 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 claims.

[0121] In particular, the shape of the pin and / or the hole and / or the eyeglass element may differ from that shown.

[0122] For example, with reference to figures 14a et 14b The free end does indeed have a finger extended by a plate, as in the described embodiment. However, the finger is then formed into a first tab, and the plate into another tab of smaller dimensions. At least one of the tabs can be formed or manufactured from sheet metal, such as a metallic sheet. Similarly, if the orifice still comprises the insertion portion and the positioning portion, the cross-section of the orifice (along a cross-sectional plane normal to the first Z-axis) is such that the insertion portion has a cross-section that is at least partially rectangular, and the positioning portion has a cross-section that is at least partially rectangular, with a first lateral end of the positioning portion opening into the insertion portion, the positioning portion being smaller than the insertion portion.Similarly, the attachment pin has a more linear shape than previously described. For example, the attachment pin is generally shaped like a plate whose main faces are designed to extend through the opening. The plate is, for example, formed or manufactured from sheet metal, such as a metal sheet. The cover of the attachment pin forms the front of the plate, and the attachment part forms the back and sides of the plate. The attachment part includes, for example, at least one snap-on tab designed to extend through the opening to lock against the back of the glasses, and preferably at least two such tabs forming a snap-on clamp. The orientation of the opening is vertical to the... figures 14a et 14b but this is obviously not limiting and the orientation of the opening can be horizontal.

[0123] For example, with reference to figures 15a et 15b The free end does indeed have a finger extended by a plate, as in the described embodiment. However, the finger is then formed into a first tab, and the plate into another, smaller tab. At least one of the tabs can be formed or manufactured from sheet metal, such as a metallic sheet. Similarly, while the opening still includes the insertion portion and the positioning portion, the cross-section of the opening (along a cross-sectional plane normal to the first Z-axis) is such that the insertion portion has a cross-section that is at least partially circular, and the positioning portion has a cross-section that is at least partially rectangular, with a first lateral end of the positioning portion opening into the insertion portion. The positioning portion is smaller than the insertion portion. The attachment pin has a cover with a circular cross-section.The attachment pin is made of plastic. The orientation of the opening is horizontal to the . figures 15a et 15b but this is obviously not limiting and the orientation of the opening can be vertical.

[0124] THE figures 16a et 16b illustrate a variant close to that associated with figures 17a et 17b with the following differences: the orientation of the orifice is horizontal but not vertical, the positioning portion being arranged in the extension of the introduction portion along the X axis, at least one snap-on tab of the attachment pin is straight and not zig-zag.

[0125] For example, with reference to figures 17a à 17c The free end is shaped into a hook. Similarly, if the orifice still comprises the insertion portion and the positioning portion, the cross-section of the orifice (along a cross-sectional plane normal to the first Z-axis) is such that the insertion portion has a cross-section that is at least partially rectangular, and the positioning portion has a cross-section that is at least partially rectangular, with a first lateral end of the positioning portion opening into the insertion portion. The positioning portion is smaller than the insertion portion. Furthermore, the orifice is provided with a base extending at least into a portion of the positioning portion, the free end surrounding the base to maintain its position. Likewise, the attachment pin has a more linear shape than previously described.For example, the attachment pin is generally shaped into a plate whose main faces are designed to extend through the opening. The plate is, for example, formed or manufactured from sheet metal, such as a metal sheet. The cover of the attachment pin forms the front of the plate, and the attachment part forms the back and sides of the plate. The attachment part includes, for example, at least one snap-on tab designed to extend through the opening to lock against the back of the glasses, and preferably at least two such tabs forming a snap-on clip. The tab may be straight or zigzag. The cover may completely cover the attachment end at the front of the glasses (as illustrated in Figure 1). figure 17b ) or only partially, or may not cover the attachment end at the front of the glasses (as illustrated in the figure 17c The orientation of the orifice is horizontal to figures 17aà 17c However, this is obviously not limiting, and the orientation of the opening can be vertical. Although the glasses shown here are frameless, they can also be framed. The lens component can then be supported either by the lens or by the frame. If the lens component is supported by the frame, the opening associated with the lens component will be formed directly in the frame so as to pass through it. Everything previously stated regarding mounting the component directly onto the lens is therefore applicable to the embodiment where the component is mounted directly onto the frame. figure 7 This illustrates such a pair of glasses in which the temple is mounted on the frame by means of a locking pin.

[0126] Whether the glasses have a frame or not, they may have two lenses or just one. In both cases, the lens component may be supported by the lens or by the frame (if the glasses have one). If the frame supports the component, the opening will be in the frame itself, rather than directly in the lens. figure 7 illustrates such a pair of glasses.

[0127] The opening may take a different shape than the one indicated. For example, the entry portion may be shaped into an oval or rectangular section (as in the figures 14a et 14b , to figures 16a et 16b , to figures 17a et 17b et 17c ), oblong ... and / or the positioning portion can be shaped into an oval or rectangular section (as in figures 14a et 14b and to figures 15a et 15b , to figures 16a et 16b , to figures 17a et 17b et 17c ), oblong ...

[0128] The orientation of the hole may also differ from what has been indicated. For example, the hole 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. figure 8 This illustrates two possible orientations of the aperture. For example, the aperture could extend substantially vertically (when the glasses are worn by the user) instead of extending substantially horizontally as described previously. Again, the insertion portion could extend above or below the positioning portion. The aperture could also extend substantially obliquely (when the glasses are worn by the user), with the insertion portion potentially closer to or further from an outer edge of the glasses than the positioning portion.

[0129] Although the cover here presents a polygonal cross-section, the cross-section could be of another shape, for example oblong or circular. If the cross-section is polygonal, it can still have a shape other than a quadrilateral and be, for example, a triangle, a hexagon, etc. Regardless of the shape of the cross-section, it must have at least one rounded corner.

[0130] Although here the pawl has a cover that completely covers the free end of the eyeglass element on the front side of the lens, the cover can be shaped to only partially cover said free end (front side of the lens) as illustrated in the figure 15b for example, it can be shaped so as not to cover said free end (front face of the glass) as illustrated in the figure 14b or to the figure 17c For example.

[0131] The attachment part may be shaped differently from what has been indicated. For example, the attachment part may include a snap-on tab, a rod extended by a foldable return so as to extend either in line with the rod or obliquely or perpendicularly to the rod..., the tab and / or the rod being intended to remain in the opening to lock the free end of the eyeglass element in position by pressing against the back face of the lens to secure the assembly (in the case of the rod, it is its return that presses against the back face of the lens to secure the assembly).

[0132] Although here the lens element is mounted from the back of the lens (and the associated pin from the front), the mounting can be reversed. The lens element will then be inserted into the opening from the front of the lens towards the back of the lens, and the pin will be inserted into the opening from the back of the lens towards the front of the lens. figure 9 This illustrates the two possible assembly methods that have just been described.

[0133] The tenon and / or the limb and / or the bridge can be made of different materials such as synthetic material, plastic, metal...

[0134] Similarly, the frame, if it exists, can be made of different materials such as synthetic material, plastic, metal...

[0135] Similarly, the game piece can be made of different materials such as synthetic material, plastic, metal...

[0136] The pawn can be made of the same material as the associated eyewear element or be made of a different material.

[0137] The frame, if it exists, may surround the lens(es) externally or only partially surround the lens(es).

[0138] The eyeglass frame may consist of only one lens.

[0139] The eyeglass component could be a bridge, a temple, a tenon, a side assembly...

[0140] The pin will be held in place in the opening without any additional fastening means, for example, by being snapped into place or by simple adjustment. Alternatively, the pin may be held in place in the opening using additional fastening means, such as a screw and nut assembly. Alternatively, a free end of the pin may be shaped to cooperate with a component that prevents the pin from being removed from the opening. For example, the free end of the pin may be threaded to cooperate with a nut (for example, inserted through the back of the lens) mounted on the pin once it is in place in the opening – the nut then preventing the pin from being removed. It is understood that in all cases, both the eyeglass component and the pin are mounted on the eyeglasses in a removable manner.

[0141] Although here the pin and the spectacle element have opposing flat surfaces, the pin and the spectacle element may have other opposing surfaces. The pin and the spectacle element may thus have complementary surfaces so that the pin and the spectacle element fit together at least partially when the pin and the spectacle element are in place in the opening. figure 12 This proposes an arrangement in which the pin has a cross-section (with cross-section plane along axis T) that is externally circular, and the portion opposite the eyepiece element has a groove to house said pin. figure 13 This design proposes an arrangement in which the pin has a cross-section (with its cross-section plane along axis T) featuring a groove in which a rounded portion is housed opposite the lens element. The lens element can thus have a cross-section at the opening that is entirely oblong.

[0142] The pin and the spectacle element may not have complementary surfaces. The pin may thus be shaped to rotate freely around its axis T. For example, the pin may have a cross-section (with its cross-section plane along axis T) that is externally circular. The pin may therefore be without a wedge, and / or the wedge may lack a flat section, and / or the pin may lack a flat surface.

[0143] Although here the aperture and the lens element present one or more complementary surfaces, the aperture and the lens element may have other opposing surfaces. For example, as visible in the figure 11 The element can be shaped so that its cross-section at the opening (with its cross-section plane along the Z-axis) presents a single area that matches the shape of the opening. For example, this area could be a flat surface A that matches the corresponding flat part of the opening. The area opposite the flat surface could, for example, be an arc. It is understood that for the comfort of the person wearing the glasses, care must be taken to ensure that the eyeglass element cannot rotate freely within the opening around the Z-axis once the pin is in place.

[0144] If the eyeglass component is a temple, said temple may be a single piece with the second part of the tenon, the temple being joined to the tenon at the hinge. Such a pair of glasses is illustrated in the figure 5Alternatively, the temple will be attached to the second part. Alternatively, the temple and the tenon will be a single piece. In this case, there will be no hinge allowing the temple to fold down. Alternatively, the piece forming the temple and tenon together will be sufficiently flexible to inherently perform the hinge function. If a hinge function is present in the glasses, the temple will be able to fold down by rotating around an axis or by another movement, such as a movement combining at least two rotations or a rotation and a translation. The glasses may thus have a hinge such as the one described by the present applicant in application FR 2 844 062.
