- the glasses 2 and 3 are also associated with lateral branches 5 and 6, making it possible to support the glasses by coming to rest by their extension on the top of the ears.
- Each of the glasses 2 or 3 is connected to the lateral branch 5 or 6 by a stud 7 according to the invention, which is immobilized relative to the glass corresponding to the right of a through hole 8 formed in the thickness of this glass, the assembly carried out avoiding in particular any offset towards the outside of the glass of the associated branch 5 or 6, which is on the contrary situated inside the apparent contour of the glass carrying the tenon on which it is articulated.
- a hubcap 9 the profile and decoration of which do not directly matter to the invention, is mounted on the external surface of each of the glasses, opposite the interior surface facing the eyes of the user, this cover being disposed on the glass in line with the through hole 8 in the manner described below.
- FIGS. 2 to 4 which relate more particularly to one of the two glasses of the pair of glasses of FIG. 1, for example the glass 2 and to the support branch 5 hinged thereon, it being understood that exactly identical arrangements are used to bring the glass 3 and the branch 6 together, we see on a larger scale how the fixing of the tenon 7 is carried out with respect to the glass and the articulation of the branch on this post, in a first embodiment of the invention.
- the tenon 7 comprises in particular a tubular body 10 disposed opposite the through hole 8 previously formed in the glass, the outside diameter of this body preferably being slightly smaller than that of the hole in order to allow it to engage there without efforts on its walls.
- the body 10 comprises a cylindrical ring 11, the lower extension 12 of which is produced in two parts 12a and 12b, as shown more particularly in the sectional view of FIG. 3, these two parts resulting from the presence therein.
- the two parts 12a and 12b have a hooking collar 13 whose role will be explained below, in particular when it forms a circular re-entrant border, once the two parts of the ring tightened and brought into contact with each other.
- the body 10 is provided to cooperate with a locking nut 14, which is adapted to the body from the outside thereof to bring the two parts 12a and 12b closer together, as shown in FIG. 4 , the assembly process used being more particularly described below.
- the body 10 has for this purpose an external thread 15, adapted to come to cooperate with a threaded bore 16 provided in the nut 14, which preferably has at its upper end through which engages the lower part of the body
- the nut 14 also comprises a flat shoulder 18 intended to come to bear against the interior surface 19 of the glass 2, with the interposition of a flexible washer 20, made of a material having a sufficient crushing capacity, this washer avoiding any direct contact between the nut and the glass.
- the tubular body 10 of the post By its end opposite the nut 14, the tubular body 10 of the post also receives a support member 21 carrying the hub cap 9 and making it possible, in this example, to immobilize the post relative to the glass.
- the support member consists of a cylindrical rod 22, the diameter of which is such that it can easily engage in the internal bore 23 of the ring 11 , this rod comprising at its upper end a projecting head 24, which is disposed slightly in front of the outer surface 25 of the glass.
- the head 24 of the rod 22 has approximately a generally spherical shape, so as to allow mounting on it, by simple pressure, the hubcap 9, which thus hides from the outside the assembly assembly and in particular conceals the end of the post 7 and in particular the tubular body 10 and the fixing nut 14.
- the hubcap 9, seen in section in a plane in Figure 2 and in a plane perpendicular to the previous one in Figure 4, can have any suitable shape, with any profile and in particular include any type of decoration on its surface external, the nature and arrangement of this possible decoration not relating to the present invention.
- the hubcap 9 comprises an external shell 26, with two re-entrant edges, respectively 27 and 28, making it possible to fix the hubcap under the head 24 of the rod 22, in the manner of a clip, in further facilitating its replacement by another, with a different decor, at the option of the user.
- a flexible washer 29 is also advantageously disposed between the outer surface 25 of the glass 2, the end of the ring 11 of the body 10 and the re-entrant edges 27 and 28 of the hubcap 9, in order to avoid, as previously, direct contact metal or hard parts with the surface of the glass, while providing a suitable bearing surface for the head 24, so as to allow the glass to be pinched between the tenon 7 and the immobilizing member 21.
- the rod 22 has at the end, at its end opposite the 'head 24, a projecting rib 30, which is arranged to come to be disposed behind the flange 13 of the tubular body 10 when its two parts 12a and 12b are tightened towards each other, thus making it possible to immobilize the rod relative to the stud 7 when the body is blocked by the nut 14 screwed onto its external surface.
- the tenon 7 is moreover arranged to allow mounting in its extension, opposite to the glass 2, the first 31 of the two hinges of a hinge 33, these two hinges being joined together by a pivot axis 34, the second 32 thereof being integral with the side branch 5 associated with the glass considered.
- the nut 14 of the tenon 7 is arranged to receive, before mounting on the tubular body 10 and installation in the latter of the rod 22 of the immobilizing member 1, the first hinge 31 which has a shoulder stop 35 with respect to a bearing 36 provided in the nut beyond its thread 16 (see Figure 4).
- the hinge 31 comprises, preferably at two diametrically opposite points, a longitudinal key 37, capable of coming to engage in a housing 38 for receiving the nut, so as to avoid any relative movement of this hinge relative to the post, the housing 38 being determined so that the branch 5, once articulated on the post around the hinge 33, is exactly positioned with respect to the glass 2 and in particular can no longer be shifted relative to the plane of the latter.
- the hinge 31 comprises, according to an arrangement which is known per se, a blind housing 39 for mounting a spring 40, bearing on the one hand against a plate 41 in the bottom of this housing, on the other hand on an inclined surface 42 of the second hinge 32, in order to allow the branch 5 to be preferably held in one or other of two positions, depending on whether it is in line with the tenon when the pair of glasses is used , or on the contrary folded towards the glasses, when it is closed.
- Figure 5 illustrates a variant which in fact differs from the previous one only in the particular structure of the immobilizing member 21 and the hubcap 9, all the other parts of the assembly remaining identical to those described in relation to the mode from previous realization.
- the hubcap 9 is directly secured to the rod 22 of the immobilizing member and ensures with this last blocking the post once the nut 14 screwed on the tubular body 10 as already indicated.
- the flexible washers 20 and 29 applied on either side of the glass 2 against the inner 19 and outer 25 surfaces make it possible to accommodate the curvature of the glass without hampering the implementation of the tenon fixing means.
- the rod 22 of the immobilizing member extends substantially in the axis of the tenon, while in the other, it is slightly offset and inclined in the direction of this axis, without modifying the principle put in play.
- the post 7 is cylindrical, the body 10 of this post no longer comprising the lateral slots of the previous variant making it play a role of pliers.
- the body 10 of the post 7 engages freely in the through hole 8 and has a transverse shoulder 50, projecting outwards from the hole and whose diameter is slightly greater than that of the latter to allow it to s 'Apply to the surface of the glass around this hole, preferably by means of a flexible washer 51 as before.
- the body 10 has an external thread 52, suitable for cooperating with an external nut 53 which, as in the embodiment seen above, has a transverse shoulder 54 which comes to rest against the glass on the side of the branch 5 opposite to the 'shoulder 50, the glass 2 being pinched between these two shoulders 50 and 54.
- a flexible washer 55 is housed between the surface of the glass and the shoulder 54 so as not to risk damaging it by direct contact with the nut 53.
- the body 10 extends beyond the glass 2, in the direction of the branch 5, so as to allow the mounting of the articulation hinge thereof, this mounting possibly being identical to that described for the first variant or else use any other equivalent solution, with a screwed connection socket, a bayonet system or the like.
- the body 10 of the post 7 may directly comprise, after manufacturing, the first hinge of the hinge, which in this case only requires precise positioning in azimuth of the post in the through hole.
- the body 10 also comprises an axial bore 56, which, as before, receives the rod 22 of the support member 21, which in this case no longer participates in the immobilization of the post 7, since the latter is directly secured to the glass between the shoulders 50 and 54, respectively of the body 10 and the nut 53.
- the post finally has, in projecting projection, in its axial bore 56, a flexible tongue 57, capable of bending towards the inside of the bore under the effect of the thrust of the rod.
- the rod 22 has a circular groove 58 where the tongue 56 can then engage with relaxation of the latter in the manner of a clip, by locking in position the rod vis-à-vis the post.
- the rod 22 which supports the hubcap 9 is independent of the body 10 of the post 7, its length 'being able in particular to be adjusted and in particular limited by appropriate cutting, depending on the type of glasses considered, depending on the depth of the bore 56 and the thickness of the glass 2.
- FIG. 7 illustrates a simplified alternative embodiment of the invention in horizontal section, in which the hinge 31 is in one piece, and fixed to the internal face 19 of the glass 2, the curvature of which it follows by means of a screw 66 with a head spherical 67, passing through the through hole 8 formed in the glass 5, the threaded end 68 of which engages in the thread 69 of a tenon 70 having the shape of a dovetail.
- the diameter of the screw 66 is slightly less than the diameter of the hole 8 so as not to cause stress on its walls;
- the assembly is carried out without the interposition of a flexible washer, but nothing prevents us from having it on either side of the glass.
- the dovetail tenon 70 comprises, on the side in contact with the external face 25 of the glass 2, a cavity 71 in which is held a spring 72 constituted by a bent metal wire: on this tenon 70 can be fixed a hubcap 9 comprising a mortise 73 in dovetail identical to that of the tenon, by simple sliding the spring 72 ensuring the locking of the fixing by snap-fastening in a groove 74 provided on the mortise 73.
- the hubcap 9 slides vertically, but it goes without saying that the sliding can be done horizontally by simple 90 ° rotation of the dovetail tenon 70.
- FIG. 8 represents, in vertical section, a last embodiment of the invention in which the hinge 31 with its articulation hinge 33 is fixed to the glass 2 by means of two tenons 7 freely engaging, each in two through holes 8, said studs comprising a transverse shoulder 50 projecting towards the outside of the hole and the diameter of which is greater than that of the latter to be applied to the external surface 25 of the glass with the interposition of a washer 51 made of flexible material .
- Each tenon 7 has an external thread 32 at its end opposite to the shoulder 50.
- each transverse branch 61 of which is provided with a tapping 62 intended to cooperate with the external thread 32 of the studs 7.
- the assembly is carried out by means of nuts 63 which are screwed onto the threaded body 32 of each post.
- the shoulder 50 of the studs can be grooved, or polygonal; in this embodiment, the pins 7 have a cylindrical axial bore 64 intended to receive the device for fixing a hubcap 9, formed of two rods 65 of diameter almost equal to that of the bores 64 of the tenons 7 but having a slight taper towards their end allowing them to be pressed "by force" into said bores 64. This arrangement ensures sufficient retention of the hubcap 9 while allowing its replacement.
- a spectacle frame of new design is thus produced, in which each lens only has a through hole, allowing the mounting of the tenon carrying each of the lateral branches, without the need for any additional piece projecting or resting on the outer edge of this lens.
- the more specially adopted method of attachment allows in all cases the implementation of an external hubcap to the right of the post and coming to be placed in front of the glass, this hubcap can be easily changed by the user without directly intervening on the post itself.
- fastening elements can be made of plastic, of the "TEFLON” type; similarly you can replace the hubcaps and clip in their place colored solar glasses, in front of colorless glasses.

Description
« MONTURE DE VERRES DE LUNETTES » "GLASSES GLASS FRAME"
La présente invention est relative à une nouvelle monture pour verres de lunettes de correction de la vue ou de protection des yeux, notamment contre le rayonnement solaire.The present invention relates to a new frame for glasses for correcting vision or protecting the eyes, in particular against solar radiation.
Dans les réalisations classiques actuelles, chacun des deux verres des lunettes est notamment serti ou emprisonné dans une monture périphérique qui l'entoure totalement ou partiellement et qui se prolonge au centre de la partie avant de ces lunettes par un arceau propre à s'appliquer sur l'arête du nez de l'utilisateur. Ces montures qui cerclent ainsi les deux verres peuvent être réalisées en tout matériau approprié, plastique, métallique ou autre, qui présente une rigidité mécanique et une tenue suffisante pour permettre d'y fixer, latéralement de chaque côté de l'ensemble, une des deux parties d'une charnière d'articulation dont l'autre est solidaire d'une branche allongée qui, à partir de la monture, se prolonge vers l'oreille de l'usager pour maintenir les lunettes en place, tout en permettant aux deux branches d'être repliées contre les verres autour de ces charnières lorsque les lunettes ne sont pas utilisées.In current conventional embodiments, each of the two lenses of the glasses is in particular crimped or trapped in a peripheral frame which surrounds it totally or partially and which is extended at the center of the front part of these glasses by a suitable arch to be applied to the bridge of the user's nose. These frames which thus encircle the two lenses can be made of any suitable material, plastic, metallic or other, which has mechanical rigidity and sufficient strength to allow one of the two to be fixed laterally on each side of the assembly. parts of an articulation hinge, the other of which is integral with an elongated branch which, starting from the frame, extends towards the user's ear to hold the glasses in place, while allowing the two branches to be folded against the glasses around these hinges when the glasses are not in use.
En variante et dans certaines réalisations plus dépouillées où la monture est aménagée pour laisser les verres presque totalement libres, notamment sans entourage, on prévoit de fixer sur chaque verre un tenon latéral, en particulier
métallique, sur lequel est directement fixée la charnière d'articulation de la branche correspondante, ce tenon étant bloqué sur le côté du verre et immobilisé par une vis ou analogue qui traverse un trou pratiqué dans le bord de ce verre et qui reçoit un écrou de blocage d'une patte radiale s'étendant jusqu'au trou à partir du bord du tenon, sur le côté extérieur du verre.As a variant and in certain more stripped embodiments where the frame is arranged to leave the lenses almost completely free, in particular without surrounds, provision is made to fix a lateral tenon on each lens, in particular metallic, on which the articulation hinge of the corresponding branch is directly fixed, this tenon being locked on the side of the glass and immobilized by a screw or the like which passes through a hole made in the edge of this glass and which receives a nut blocking of a radial tab extending to the hole from the edge of the post, on the outside of the glass.
Mais ces solutions, en particulier la seconde, exigent que les branches des lunettes débordent vers l'extérieur des verres, du fait du montage latéral du tenon sur lequel est fixée la charnière d'articulation de la branche correspondante, ce qui n'est pas esthétique si l'on souhaite au contraire disposer d'une partie avant des lunettes quasi totalement libre, où notamment les verres cachent les branches, seul étant apparent, en dehors de ces verres, l'arceau nasal de liaison entre ceux-ci et les petites barrettes ou plaquettes qui s'appuient de façon ordinaire de chaque côté du nez.However, these solutions, in particular the second, require that the arms of the glasses project outwards from the lenses, due to the lateral mounting of the post on which the articulation hinge of the corresponding arm is fixed, which is not aesthetic if on the contrary one wishes to have a front part of the glasses almost completely free, where in particular the glasses hide the branches, only being apparent, apart from these glasses, the nasal arch of connection between these and the small bars or platelets that usually rest on either side of the nose.
L'invention concerne une monture de verres de lunettes, qui évite ces inconvénients.The invention relates to a frame for spectacle lenses, which avoids these drawbacks.
A cet effet, la monture considérée, comportant une partie avant constituée de deux verres dépourvus d'encadrement extérieur, réunis seulement en partie centrale par un arceau de liaison nasal et deux branches latérales de support sur le
dessus des oreilles de l'usager, articulées, soit pour se débattre vers l'extérieur, soit pour se rabattre l'une et l'autre contre les verres, se caractérise en ce que chaque verre comporte, au voisinage de son bord extérieur, un trou entièrement traversant, dans lequel, du côté des branches est disposée l'extrémité d'un tenon s'étendant sensiblement perpendiculairement à la surface du verre et rendu solidaire de celui-ci, ce tenon se prolongeant, à partir de cette surface, pour permettre le montage, à son extrémité opposée, d'une charnière d'articulation d'une de ces branches latérales, le tenon étant percé d'un alésage pour l'engagement dans l'axe du trou traversant d'un organe de support constitué par une tige munie d'une tête débordante, de forme générale sphérique, sur laquelle peut être monté un enjoliveur, appliqué contre la surface extérieure du verre pour cacher la tige et le tenon.To this end, the frame in question, comprising a front part made up of two lenses without external frame, joined only in the central part by a nasal link arch and two lateral support arms on the above the ears of the user, articulated, either for struggling towards the outside, or for folding one and the other against the glasses, is characterized in that each glass comprises, in the vicinity of its outer edge, a completely through hole, in which, on the side of the branches, is disposed the end of a tenon extending substantially perpendicularly to the surface of the glass and made integral with the latter, this tenon extending from this surface, to allow the mounting, at its opposite end, of a hinge for articulation of one of these lateral branches, the post being pierced with a bore for engagement in the axis of the through hole of a support member consisting of a rod provided with an overhanging head, of generally spherical shape, on which a cover can be mounted, applied against the external surface of the glass to hide the rod and the tenon.
Dans un mode de réalisation particulier, le tenon comporte un corps tubulaire, l'organe de support assurant l'immobilisation du tenon et comprenant en bout, à son extrémité opposée qui s'engage dans l'alésage du tenon, une nervure circulaire en saillie apte à venir se verrouiller sur une collerette d'accrochage prévue sur le corps.In a particular embodiment, the post comprises a tubular body, the support member ensuring the immobilization of the post and comprising at the end, at its opposite end which engages in the bore of the post, a projecting circular rib able to lock onto a fastening flange provided on the body.
Avantageusement et dans ce mode de réalisation, le corps tubulaire du tenon est cylindrique et comporte au moins deux
fentes longitudinales, diamétralement opposées afin de conférer à la collerette d'accrochage une relative élasticité en extension pour le passage de la nervure circulaire de la tige de l'organe de support.Advantageously and in this embodiment, the tubular body of the post is cylindrical and comprises at least two longitudinal, diametrically opposite slots in order to give the hooking collar relative elasticity in extension for the passage of the circular rib of the rod of the support member.
Dans ce cas également, le corps tubulaire du tenon comprend un filetage externe, propre à coopérer avec une bague formant écrou de blocage comportant un pas de vis interne correspondant au filetage du corps, de telle sorte que le montage de l'écrou sur ce corps provoque le resserrement progressif de la collerette d'accrochage derrière la nervure circulaire de la tige.In this case also, the tubular body of the post comprises an external thread, suitable for cooperating with a ring forming a locking nut comprising an internal screw pitch corresponding to the thread of the body, so that the mounting of the nut on this body causes the progressive tightening of the coupling flange behind the circular rib of the rod.
Dans cette première variante, la tête de la tige de l'organe de support est en appui sur la surface extérieure du verre, de préférence par l'intermédiaire d'une rondelle souple partiellement écrasée par la tête lorsqu'elle est appliquée contre cette surface.In this first variant, the head of the rod of the support member is in abutment on the external surface of the glass, preferably by means of a flexible washer partially crushed by the head when it is applied against this surface .
Dans un autre mode de réalisation plus simple, le tenon comporte, à son extrémité opposée à la branche latérale, vers l'extérieur du trou traversant, un epaulement transversal en appui sur la surface du verre, cet epaulement débordant circonférentiellement dans l'alésage axial du tenon par une languette souple en saillie transversale, propre à fléchir légèrement en direction de la branche latérale lors de
l'introduction de la tige de l'organe de support et à se détendre à la manière d'un clip dans une rainure circulaire de cette tige lorsque celle-ci est enfoncée dans l'alésage, en la bloquant en position.In another simpler embodiment, the tenon comprises, at its end opposite the lateral branch, towards the outside of the through hole, a transverse shoulder bearing on the surface of the glass, this shoulder projecting circumferentially into the axial bore of the post by a flexible tongue projecting transversely, adapted to bend slightly in the direction of the lateral branch when the introduction of the rod of the support member and to relax in the manner of a clip in a circular groove of this rod when the latter is pressed into the bore, locking it in position.
De préférence et de façon similaire aux dispositions mises en oeuvre dans la première variante, l'épaulement du tenon s'appuie sur le verre par l'intermédiaire d'une rondelle souple.Preferably and similarly to the arrangements implemented in the first variant, the shoulder of the post is supported on the glass by means of a flexible washer.
Par ailleurs et également dans cette seconde variante, le tenon comporte un corps tubulaire cylindrique, muni d'un filetage externe coopérant avec un écrou de blocage, le verre étant serré entre l'épaulement transversal du tenon et cet écrou.Furthermore and also in this second variant, the post comprises a cylindrical tubular body, provided with an external thread cooperating with a locking nut, the glass being clamped between the transverse shoulder of the post and this nut.
A nouveau, l'épaulement de l'écrou s'applique sur la surface intérieure du verre avec interposition d'une rondelle souple analogue, le verre étant ainsi pincé entre deux rondelles, en évitant tout contact direct avec une partie métallique ou rigide du tenon, de l'organe de support ou de l'écrou de blocage.Again, the shoulder of the nut is applied to the interior surface of the glass with the interposition of a similar flexible washer, the glass thus being pinched between two washers, avoiding any direct contact with a metallic or rigid part of the tenon. , the support member or the locking nut.
Selon l'une ou l'autre de ces deux variantes, l'écrou de blocage comporte à une de ses extrémités un epaulement apte à venir en appui sur la surface du verre pour immobiliser le tenon dans le trou traversant.According to either of these two variants, the locking nut comprises at one of its ends a shoulder capable of coming to bear on the surface of the glass to immobilize the post in the through hole.
Dans tous les cas et selon encore une autre caractéristique complémentaire, le corps du tenon comporte, à l'opposé du
verre, un prolongement tubulaire recevant la première des deux paumelles d'une charnière d'articulation, dont la seconde porte la branche latérale correspondante. Avantageusement, la paumelle qui pénètre dans le prolongement tubulaire du tenon comprend une clavette longitudinale, propre à s'engager dans un logement de réception du tenon, de manière à éviter toute rotation relative de cette paumelle par rapport au tenon, l'articulation de la charnière étant orientée en fonction de la convexité du verre correspondant.In all cases and according to yet another additional characteristic, the body of the post comprises, opposite the glass, a tubular extension receiving the first of the two hinges of a hinge, the second of which carries the corresponding lateral branch. Advantageously, the hinge which penetrates into the tubular extension of the post comprises a longitudinal key, suitable for engaging in a housing for receiving the post, so as to avoid any relative rotation of this hinge relative to the post, the articulation of the hinge being oriented as a function of the convexity of the corresponding glass.
De préférence également mais de façon non exclusive, la seconde des paumelles de la charnière comporte, selon une disposition en elle-même connue, une surface inclinée formant came et coopérant avec un ressort logé dans un évidement borgne prévu en bout de la première paumelle, afin de maintenir la branche dans l'une ou l'autre de deux positions, selon le cas, ouverte ou rabattue sur les verres des lunettes.Preferably also, but not exclusively, the second of the hinges of the hinge comprises, according to an arrangement known per se, an inclined surface forming a cam and cooperating with a spring housed in a blind recess provided at the end of the first hinge, in order to keep the branch in one or other of two positions, as the case may be, open or folded over the lenses of the glasses.

Sur la vue en perspective de la Figure 1 , la référence 1 désigne dans son ensemble une paire de lunettes, comportant de façon entièrement banale pour ce type de produit, deux verres respectivement 2 et 3, pour corriger la vue ou de protection solaire, ces verres étant réunis en partie centrale des lunettes par un arceau de liaison 4 destiné à venir s'appuyer sur l'arête du nez de l'utilisateur, par l'intermédiaire de plaquettes latérales telles que 4a notamment. Les verres 2 et 3 sont par ailleurs associés à des branches latérales 5 et 6, permettant de supporter les lunettes en venant reposer par leur prolongement sur le dessus des oreilles.In the perspective view of FIG. 1, the reference 1 designates as a whole a pair of glasses, comprising completely banal for this type of product, two glasses respectively 2 and 3, to correct the view or sun protection, these glasses being joined in the central part of the glasses by a connecting hoop 4 intended to come to bear on the edge of the nose of the user, by means of lateral plates such as 4a in particular. The glasses 2 and 3 are also associated with lateral branches 5 and 6, making it possible to support the glasses by coming to rest by their extension on the top of the ears.
Chacun des verres 2 ou 3 est relié à la branche latérale 5 ou 6 par un tenon 7 conforme à l'invention, lequel est immobilisé par rapport au verre correspondant au droit d'un trou traversant 8 ménagé dans l'épaisseur de ce verre, le montage réalisé évitant en particulier tout décalage vers l'extérieur du verre de la branche 5 ou 6 associée, qui se situe au contraire à l'intérieur du contour apparent du verre portant le tenon sur lequel elle est articulée.Each of the glasses 2 or 3 is connected to the lateral branch 5 or 6 by a stud 7 according to the invention, which is immobilized relative to the glass corresponding to the right of a through hole 8 formed in the thickness of this glass, the assembly carried out avoiding in particular any offset towards the outside of the glass of the associated branch 5 or 6, which is on the contrary situated inside the apparent contour of the glass carrying the tenon on which it is articulated.
Un enjoliveur 9, dont le profil et le décor n'importent pas directement à l'invention, est monté sur la surface extérieure de
chacun des verres, opposée à la surface intérieure en regard des yeux de l'utilisateur, cet enjoliveur étant disposé sur le verre au droit du trou traversant 8 de la manière décrite ci- après.A hubcap 9, the profile and decoration of which do not directly matter to the invention, is mounted on the external surface of each of the glasses, opposite the interior surface facing the eyes of the user, this cover being disposed on the glass in line with the through hole 8 in the manner described below.
En se référant ainsi aux Figures 2 à 4, qui se rapportent plus particulièrement à l'un des deux verres de la paire de lunettes de la Figure 1 , par exemple le verre 2 et à la branche de support 5 articulée sur celui-ci, étant entendu que des dispositions exactement identiques sont mises en oeuvre pour réunir le verre 3 et la branche 6, on voit à plus grande échelle comment est réalisée la fixation du tenon 7 vis-à-vis du verre et l'articulation de la branche sur ce tenon, dans un premier mode de réalisation de l'invention.Referring thus to FIGS. 2 to 4, which relate more particularly to one of the two glasses of the pair of glasses of FIG. 1, for example the glass 2 and to the support branch 5 hinged thereon, it being understood that exactly identical arrangements are used to bring the glass 3 and the branch 6 together, we see on a larger scale how the fixing of the tenon 7 is carried out with respect to the glass and the articulation of the branch on this post, in a first embodiment of the invention.
Le tenon 7 comporte notamment un corps tubulaire 10 disposé en regard du trou traversant 8 préalablement ménagé dans le verre, le diamètre extérieur de ce corps étant de préférence légèrement inférieur à celui du trou afin de lui permettre de s'y engager sans efforts sur ses parois.The tenon 7 comprises in particular a tubular body 10 disposed opposite the through hole 8 previously formed in the glass, the outside diameter of this body preferably being slightly smaller than that of the hole in order to allow it to engage there without efforts on its walls.
De préférence, le corps 10 comporte une bague cylindrique 11 , dont le prolongement inférieur 12 est réalisé en deux parties 12a et 12b, comme le montre plus particulièrement la vue en coupe de la Figure 3, ces deux parties résultant de la présence dans celui-ci de deux fentes latérales et
longitudinales, diamétralement opposées et aptes à conférer au corps 10 une relative élasticité, à la manière des deux mâchoires d'une pince normalement légèrement écartées l'une de l'autre mais susceptibles de se rapprocher mutuellement sous un effort de serrage radial approprié.Preferably, the body 10 comprises a cylindrical ring 11, the lower extension 12 of which is produced in two parts 12a and 12b, as shown more particularly in the sectional view of FIG. 3, these two parts resulting from the presence therein. ci of two side slits and longitudinal, diametrically opposite and capable of giving the body 10 relative elasticity, in the manner of the two jaws of a clamp normally slightly spaced from each other but capable of approaching each other under an appropriate radial clamping force.
A leur extrémité inférieur, opposée à la bague cylindrique 11 , les deux parties 12a et 12b comportent une collerette d'accrochage 13 dont le rôle sera précisé ci-après, notamment lorsqu'elle forme une bordure rentrante circulaire, une fois les deux parties de la bague serrées et mises en contact l'une avec l'autre.At their lower end, opposite the cylindrical ring 11, the two parts 12a and 12b have a hooking collar 13 whose role will be explained below, in particular when it forms a circular re-entrant border, once the two parts of the ring tightened and brought into contact with each other.
A cet effet, le corps 10 est prévu pour coopérer avec un écrou de blocage 14, venant s'adapter sur le corps par l'extérieur de celui-ci pour réaliser le rapprochement des deux parties 12a et 12b, comme schématisé sur la Figure 4, le processus de montage mis en oeuvre étant en outre plus particulièrement décrit ci-après.To this end, the body 10 is provided to cooperate with a locking nut 14, which is adapted to the body from the outside thereof to bring the two parts 12a and 12b closer together, as shown in FIG. 4 , the assembly process used being more particularly described below.
Le corps 10 comporte à cet effet un filetage externe 15, adapté à venir coopérer avec un alésage taraudé 16 prévu dans l'écrou 14, lequel présente de préférence à son extrémité supérieure par laquelle s'engage la partie inférieure du corpsThe body 10 has for this purpose an external thread 15, adapted to come to cooperate with a threaded bore 16 provided in the nut 14, which preferably has at its upper end through which engages the lower part of the body
10 un chanfrein conique 17, facilitant l'engagement du corps
dans l'écrou et la venue en prise du premier filet de ce dernier sur le filetage du corps.10 a conical chamfer 17, facilitating the engagement of the body in the nut and the engagement of the first thread of the latter on the thread of the body.
L'écrou 14 comporte par ailleurs un epaulement plat 18 destiné à venir s'appliquer contre la surface intérieure 19 du verre 2, avec interposition d'une rondelle souple 20, en un matériau présentant une faculté d'écrasement suffisante, cette rondelle évitant tout contact direct entre l'écrou et le verre.The nut 14 also comprises a flat shoulder 18 intended to come to bear against the interior surface 19 of the glass 2, with the interposition of a flexible washer 20, made of a material having a sufficient crushing capacity, this washer avoiding any direct contact between the nut and the glass.
Par son extrémité opposée à l'écrou 14, le corps tubulaire 10 du tenon reçoit par ailleurs un organe de support 21 portant l'enjoliveur 9 et permettant dans cet exemple de réaliser l'immobilisation du tenon par rapport au verre.By its end opposite the nut 14, the tubular body 10 of the post also receives a support member 21 carrying the hub cap 9 and making it possible, in this example, to immobilize the post relative to the glass.
Dans cet exemple, représenté sur les Figures 2 à 4, l'organe de support se compose d'une tige cylindrique 22, dont le diamètre est tel qu'elle puisse s'engager sans difficultés dans l'alésage interne 23 de la bague 11 , cette tige comportant à son extrémité supérieure une tête débordante 24, laquelle est disposée légèrement en avant de la surface extérieure 25 du verre.In this example, shown in Figures 2 to 4, the support member consists of a cylindrical rod 22, the diameter of which is such that it can easily engage in the internal bore 23 of the ring 11 , this rod comprising at its upper end a projecting head 24, which is disposed slightly in front of the outer surface 25 of the glass.
La tête 24 de la tige 22 présente approximativement une forme générale spherique, de manière à permettre le montage sur elle, par simple pression, de l'enjoliveur 9, qui vient ainsi cacher de l'extérieur l'ensemble du montage et en particulier
dissimule I' extrémité du tenon 7 et notamment le corps tubulaire 10 et l'écrou de fixation 14.The head 24 of the rod 22 has approximately a generally spherical shape, so as to allow mounting on it, by simple pressure, the hubcap 9, which thus hides from the outside the assembly assembly and in particular conceals the end of the post 7 and in particular the tubular body 10 and the fixing nut 14.
L'enjoliveur 9, vu en coupe dans un plan sur la Figure 2 et dans un plan perpendiculaire au précédent sur la Figure 4, peut avoir toute forme appropriée, avec un profil quelconque et notamment comporter n'importe quel type de décoration sur sa surface externe, la nature et la disposition de cette décoration éventuelle ne concernant pas la présente invention.The hubcap 9, seen in section in a plane in Figure 2 and in a plane perpendicular to the previous one in Figure 4, can have any suitable shape, with any profile and in particular include any type of decoration on its surface external, the nature and arrangement of this possible decoration not relating to the present invention.
Dans l'exemple représenté, l'enjoliveur 9 comporte une coque externe 26, avec deux bords rentrants, respectivement 27 et 28, permettant de fixer l'enjoliveur sous la tête 24 de la tige 22, à la manière d'un clip, en facilitant en outre son remplacement par un autre, comportant un décor différent, au gré de l'utilisateur.In the example shown, the hubcap 9 comprises an external shell 26, with two re-entrant edges, respectively 27 and 28, making it possible to fix the hubcap under the head 24 of the rod 22, in the manner of a clip, in further facilitating its replacement by another, with a different decor, at the option of the user.
Une rondelle souple 29 est par ailleurs avantageusement disposée entre la surface extérieure 25 du verre 2, l'extrémité de la bague 11 du corps 10 et les bords rentrants 27 et 28 de l'enjoliveur 9, afin d'éviter comme précédemment un contact direct de parties métalliques ou dures avec la surface du verre, tout en procurant une portée d'appui convenable pour la tête 24, de manière à permettre le pincement du verre entre le tenon 7 et l'organe d'immobilisation 21.
Dans ce but, la tige 22 comporte en bout, à son extrémité opposée à la' tête 24, une nervure en saillie 30, laquelle est agencée pour venir se disposer derrière la collerette 13 du corps tubulaire 10 lorsque ses deux parties 12a et 12b sont serrées l'une vers l'autre, en permettant ainsi d'immobiliser la tige par rapport au tenon 7 lorsque le corps est bloqué par l'écrou 14 vissé sur sa surface externe.A flexible washer 29 is also advantageously disposed between the outer surface 25 of the glass 2, the end of the ring 11 of the body 10 and the re-entrant edges 27 and 28 of the hubcap 9, in order to avoid, as previously, direct contact metal or hard parts with the surface of the glass, while providing a suitable bearing surface for the head 24, so as to allow the glass to be pinched between the tenon 7 and the immobilizing member 21. For this purpose, the rod 22 has at the end, at its end opposite the 'head 24, a projecting rib 30, which is arranged to come to be disposed behind the flange 13 of the tubular body 10 when its two parts 12a and 12b are tightened towards each other, thus making it possible to immobilize the rod relative to the stud 7 when the body is blocked by the nut 14 screwed onto its external surface.
Dans l'exemple considéré, le tenon 7 est par ailleurs aménagé pour permettre de monter dans son prolongement, à l'opposé du verre 2, la première 31 des deux paumelles d'une charnière d'articulation 33, ces deux paumelles étant réunies ensemble par un axe de pivotement 34, la seconde 32 de celles-ci étant solidaire de la branche latérale 5 associée au verre considéré.In the example considered, the tenon 7 is moreover arranged to allow mounting in its extension, opposite to the glass 2, the first 31 of the two hinges of a hinge 33, these two hinges being joined together by a pivot axis 34, the second 32 thereof being integral with the side branch 5 associated with the glass considered.
Notamment, l'écrou 14 du tenon 7 est aménagé pour recevoir, avant montage sur le corps tubulaire 10 et mise en place dans celui-ci de la tige 22 de l'organe d'immobilisation 1 , la première paumelle 31 qui comporte un epaulement d'arrêt 35 vis-à-vis d'une portée 36 prévue dans l'écrou au-delà de son filetage 16 (voir Figure 4).In particular, the nut 14 of the tenon 7 is arranged to receive, before mounting on the tubular body 10 and installation in the latter of the rod 22 of the immobilizing member 1, the first hinge 31 which has a shoulder stop 35 with respect to a bearing 36 provided in the nut beyond its thread 16 (see Figure 4).
La paumelle 31 comporte, de préférence en deux points diamétralement opposés, une clavette longitudinale 37, apte à venir s'engager dans un logement de réception 38 de l'écrou,
de manière à éviter tout mouvement relatif de cette paumelle par rapport au tenon, le logement 38 étant déterminé pour que la branche 5, une fois articulée sur le tenon autour de la charnière 33, soit exactement positionnée vis-à-vis du verre 2 et notamment ne puisse plus ensuite se décaler par rapport au plan de ce dernier.The hinge 31 comprises, preferably at two diametrically opposite points, a longitudinal key 37, capable of coming to engage in a housing 38 for receiving the nut, so as to avoid any relative movement of this hinge relative to the post, the housing 38 being determined so that the branch 5, once articulated on the post around the hinge 33, is exactly positioned with respect to the glass 2 and in particular can no longer be shifted relative to the plane of the latter.
Avantageusement, la paumelle 31 comporte, selon une disposition en elle-même connue, un logement borgne 39 pour le montage d'un ressort 40, en appui d'une part contre une plaquette 41 dans le fond de ce logement, d'autre part sur une surface inclinée 42 de la seconde paumelle 32, afin de permettre de maintenir préférentiel lement la branche 5 dans l'une ou l'autre de deux positions, selon qu'elle est dans le prolongement du tenon lorsque la paire de lunettes est utilisée, ou au contraire rabattue en direction des verres, lorsqu'elle est refermée.Advantageously, the hinge 31 comprises, according to an arrangement which is known per se, a blind housing 39 for mounting a spring 40, bearing on the one hand against a plate 41 in the bottom of this housing, on the other hand on an inclined surface 42 of the second hinge 32, in order to allow the branch 5 to be preferably held in one or other of two positions, depending on whether it is in line with the tenon when the pair of glasses is used , or on the contrary folded towards the glasses, when it is closed.
La Figure 5 illustre une variante qui ne diffère en fait de la précédente que par la structure particulière de l'organe d'immobilisation 21 et de l'enjoliveur 9, toutes les autres parties du montage restant identiques à celles décrites en relation avec le mode de réalisation précédent.Figure 5 illustrates a variant which in fact differs from the previous one only in the particular structure of the immobilizing member 21 and the hubcap 9, all the other parts of the assembly remaining identical to those described in relation to the mode from previous realization.
Dans ce cas, l'enjoliveur 9 est directement solidarisé de la tige 22 de l'organe d'immobilisation et assure avec cette
dernière le blocage du tenon une fois l'écrou 14 vissé sur le corps tubulaire 10 comme déjà indiqué.In this case, the hubcap 9 is directly secured to the rod 22 of the immobilizing member and ensures with this last blocking the post once the nut 14 screwed on the tubular body 10 as already indicated.
A noter que, dans l'un comme dans l'autre des deux modes de réalisation envisagés, les rondelles souples 20 et 29 appliquées de part et d'autre du verre 2 contre les surfaces intérieure 19 et extérieure 25, permettent d'accommoder la courbure du verre sans gêner la mise en oeuvre des moyens de fixation du tenon. Dans la première variante, la tige 22 de l'organe d'immobilisation s'étend sensiblement dans l'axe du tenon, alors que dans l'autre, elle est légèrement décalée et inclinée sur la direction de cet axe, sans modifier le principe mis en jeu.Note that, in both of the two embodiments envisaged, the flexible washers 20 and 29 applied on either side of the glass 2 against the inner 19 and outer 25 surfaces, make it possible to accommodate the curvature of the glass without hampering the implementation of the tenon fixing means. In the first variant, the rod 22 of the immobilizing member extends substantially in the axis of the tenon, while in the other, it is slightly offset and inclined in the direction of this axis, without modifying the principle put in play.
Dans le cas d'un autre exemple de réalisation plus simplifié, tel qu'illustré sur la Figure 6, le tenon 7 est cylindrique, le corps 10 de ce tenon ne comportant plus les fentes latérales de la variante précédente lui faisant jouer un rôle de pince.In the case of another more simplified exemplary embodiment, as illustrated in FIG. 6, the post 7 is cylindrical, the body 10 of this post no longer comprising the lateral slots of the previous variant making it play a role of pliers.
Dans ce cas, le corps 10 du tenon 7 s'engage librement dans le trou traversant 8 et comporte un epaulement transversal 50, débordant vers l'extérieur du trou et dont le diamètre est légèrement supérieur à celui de ce dernier pour lui permettre de s'appliquer sur la surface du verre autour de ce trou, de préférence par l'intermédiaire d'une rondelle souple 51 comme précédemment.
Le corps 10 présente un filetage externe 52, propre à coopérer avec un écrou extérieur 53 qui, comme dans le mode de réalisation vu plus haut, comporte un epaulement transversal 54 venant s'appliquer contre le verre du côté de la branche 5 opposé à l'épaulement 50, le verre 2 étant pincé entre ces deux épaulements 50 et 54. A nouveau, une rondelle souple 55 est logée entre la surface du verre et l'épaulement 54 pour ne pas risquer de le détériorer par contact direct avec l'écrou 53.In this case, the body 10 of the post 7 engages freely in the through hole 8 and has a transverse shoulder 50, projecting outwards from the hole and whose diameter is slightly greater than that of the latter to allow it to s 'Apply to the surface of the glass around this hole, preferably by means of a flexible washer 51 as before. The body 10 has an external thread 52, suitable for cooperating with an external nut 53 which, as in the embodiment seen above, has a transverse shoulder 54 which comes to rest against the glass on the side of the branch 5 opposite to the 'shoulder 50, the glass 2 being pinched between these two shoulders 50 and 54. Again, a flexible washer 55 is housed between the surface of the glass and the shoulder 54 so as not to risk damaging it by direct contact with the nut 53.
Le corps 10 se prolonge au-delà du verre 2, en direction de la branche 5, de manière à permettre le montage de la charnière d'articulation de celle-ci, ce montage pouvant être identique à celui décrit pour la première variante ou bien utiliser toute autre solution équivalente, avec une douille de liaison vissée, un système à baïonnette ou analogue.The body 10 extends beyond the glass 2, in the direction of the branch 5, so as to allow the mounting of the articulation hinge thereof, this mounting possibly being identical to that described for the first variant or else use any other equivalent solution, with a screwed connection socket, a bayonet system or the like.
Notamment, le corps 10 du tenon 7 peut directement comporter, venue de fabrication, la première paumelle de la charnière, ce qui dans ce cas exige seulement un positionnement précis en azimut du tenon dans le trou traversant.In particular, the body 10 of the post 7 may directly comprise, after manufacturing, the first hinge of the hinge, which in this case only requires precise positioning in azimuth of the post in the through hole.
Le corps 10 comporte par ailleurs un alésage axial 56, qui, comme précédemment, reçoit la tige 22 de l'organe de support 21 , laquelle dans ce cas ne participe plus à l'immobilisation du
tenon 7, puisque celui-ci est directement solidarisé du verre entre les épaulements 50 et 54, respectivement du corps 10 et de l'écrou 53.The body 10 also comprises an axial bore 56, which, as before, receives the rod 22 of the support member 21, which in this case no longer participates in the immobilization of the post 7, since the latter is directly secured to the glass between the shoulders 50 and 54, respectively of the body 10 and the nut 53.
Le tenon présente enfin, en saillie débordante, dans son alésage axial 56, une languette souple 57, capable de fléchir vers l'intérieur de l'alésage sous l'effet de la poussée de la tigeThe post finally has, in projecting projection, in its axial bore 56, a flexible tongue 57, capable of bending towards the inside of the bore under the effect of the thrust of the rod.
22 lorsque celle-ci est introduite par l'extérieur du verre dans cet alésage.22 when the latter is introduced from the outside of the glass into this bore.
La tige 22 comporte une rainure circulaire 58 où la languette 56 peut alors s'engager avec détente de celle-ci à la manière d'un clip, en bloquant en position la tige vis-à-vis du tenon.The rod 22 has a circular groove 58 where the tongue 56 can then engage with relaxation of the latter in the manner of a clip, by locking in position the rod vis-à-vis the post.
Dans cette position, la tête 24 de la tige 22 émerge légèrement au-dessus de l'épaulement 50, cette tête recevant un enjoliveur 9 qui peut être changé à volonté par l'utilisateur, par simple montage sur cette tête, la tige 22 pouvant être substituée sans aucune difficulté, chaque fois que l'usager souhaite modifier l'enjoliveur et le remplacer par un autre, différent dans son coloris, sa forme ou son aspect extérieur.In this position, the head 24 of the rod 22 emerges slightly above the shoulder 50, this head receiving a cover 9 which can be changed at will by the user, by simple mounting on this head, the rod 22 being able to be replaced without any difficulty, each time the user wishes to modify the hubcap and replace it with another one, different in its color, shape or external appearance.
A noter que dans cette variante, la tige 22 qui supporte l'enjoliveur 9 est indépendante du corps 10 du tenon 7, sa longueur 'pouvant notamment être ajustée et en particulier limitée par sectionnement approprié, en fonction du type de
lunettes considéré, selon la profondeur de l'alésage 56 et l'épaisseur du verre 2.Note that in this variant, the rod 22 which supports the hubcap 9 is independent of the body 10 of the post 7, its length 'being able in particular to be adjusted and in particular limited by appropriate cutting, depending on the type of glasses considered, depending on the depth of the bore 56 and the thickness of the glass 2.
La figure 7 illustre une variante de réalisation simplifiée de l'invention en coupe horizontale, dans laquelle la paumelle 31 est monobloc, et fixée sur la face interne 19 du verre 2, dont elle épouse la courbure au moyen d'une vis 66 à tête spherique 67, passant par le trou 8 traversant ménagé dans le verre 5 dont l'extrémité filetée 68 s'engage dans le taraudage 69 d'un tenon 70 ayant la forme d'une queue d'aronde. Dans l'exemple représenté, le diamètre de la vis 66 est légèrement inférieur au diamètre du trou 8 afin de ne pas provoquer d'effort sur ses parois; de même le montage est effectué sans interposition de rondelle souple mais rien n'empêche à ce que l'on en dispose de part et d'autre du verre.FIG. 7 illustrates a simplified alternative embodiment of the invention in horizontal section, in which the hinge 31 is in one piece, and fixed to the internal face 19 of the glass 2, the curvature of which it follows by means of a screw 66 with a head spherical 67, passing through the through hole 8 formed in the glass 5, the threaded end 68 of which engages in the thread 69 of a tenon 70 having the shape of a dovetail. In the example shown, the diameter of the screw 66 is slightly less than the diameter of the hole 8 so as not to cause stress on its walls; Similarly, the assembly is carried out without the interposition of a flexible washer, but nothing prevents us from having it on either side of the glass.
Le tenon en queue d'aronde 70 comporte du côté en contact avec la face externe 25 du verre 2, une cavité 71 dans laquelle est maintenu un ressort 72 constitué par un fil métallique recourbé : sur ce tenon 70 peut être fixé un enjoliveur 9 comportant une mortaise 73 en queue d'aronde identique à celle du tenon, par simple coulissement le ressort 72 assurant le verrouillage de la fixation par encliquetage dans une rainure 74 prévue sur la mortaise 73.
Dans l'exemple représenté, l'enjoliveur 9 coulisse verticalement, mais il va de soi que le coulissement peut se faire horizontalement par simple rotation de 90° du tenon en queue d'aronde 70.The dovetail tenon 70 comprises, on the side in contact with the external face 25 of the glass 2, a cavity 71 in which is held a spring 72 constituted by a bent metal wire: on this tenon 70 can be fixed a hubcap 9 comprising a mortise 73 in dovetail identical to that of the tenon, by simple sliding the spring 72 ensuring the locking of the fixing by snap-fastening in a groove 74 provided on the mortise 73. In the example shown, the hubcap 9 slides vertically, but it goes without saying that the sliding can be done horizontally by simple 90 ° rotation of the dovetail tenon 70.
La figure 8 représente, en coupe verticale, un dernier mode de réalisation de l'invention dans lequel la paumelle 31 avec sa charnière d'articulation 33 est fixée au verre 2 au moyen de deux tenons 7 s'engageant librement, chacun, dans deux trous traversant 8, lesdits tenons comportant un epaulement transversal 50 débordant vers l'extérieur du trou et dont le diamètre est supérieur à celui de ce dernier pour s'appliquer sur la surface externe 25 du verre avec interposition d'une rondelle 51 en matière souple. Chaque tenon 7 comporte un filetage externe 32 à son extrémité opposé à l'épaulement 50. Sur ces tenons 7 est monté avec interposition d'une rondelle élastique 55, sur la face interne 19 du verre 2 la paumelle 31 qui comporte une extrémité en « T » 60 dont chaque branche transversale 61 est munie d'un taraudage 62 destiné à coopérer avec le filetage externe 32 des tenons 7. La fixation de l'ensemble s'effectue au moyen d'écrous 63 se vissant sur le corps fileté 32 de chaque tenon. Pour faciliter le serrage avec un tournevis ou une clé l'épaulement 50 des tenons peut être rainure, ou polygonal; dans cette réalisation, les tenons 7 comportent un alésage axial cylindrique 64 destiné à recevoir
le dispositif de fixation d'un enjoliveur 9, formé de deux tiges 65 de diamètre presqu'égal à celui des alésages 64 des tenons 7 mais ayant une faible conicité vers leur extrémité permettant leur enfoncement « à force » dans lesdits alésages 64. Cette disposition assure un maintien suffisant de l'enjoliveur 9 tout en permettant son remplacement.FIG. 8 represents, in vertical section, a last embodiment of the invention in which the hinge 31 with its articulation hinge 33 is fixed to the glass 2 by means of two tenons 7 freely engaging, each in two through holes 8, said studs comprising a transverse shoulder 50 projecting towards the outside of the hole and the diameter of which is greater than that of the latter to be applied to the external surface 25 of the glass with the interposition of a washer 51 made of flexible material . Each tenon 7 has an external thread 32 at its end opposite to the shoulder 50. On these tenons 7 is mounted with the interposition of an elastic washer 55, on the internal face 19 of the glass 2 the hinge 31 which has one end in " T ”60, each transverse branch 61 of which is provided with a tapping 62 intended to cooperate with the external thread 32 of the studs 7. The assembly is carried out by means of nuts 63 which are screwed onto the threaded body 32 of each post. To facilitate tightening with a screwdriver or a key, the shoulder 50 of the studs can be grooved, or polygonal; in this embodiment, the pins 7 have a cylindrical axial bore 64 intended to receive the device for fixing a hubcap 9, formed of two rods 65 of diameter almost equal to that of the bores 64 of the tenons 7 but having a slight taper towards their end allowing them to be pressed "by force" into said bores 64. This arrangement ensures sufficient retention of the hubcap 9 while allowing its replacement.
On réalise ainsi une monture de lunettes de conception nouvelle, dans laquelle chaque verre comporte seulement un trou traversant, permettant le montage du tenon portant chacune des branches latérales, sans nécessité aucune pièce complémentaire débordant ou en appui du bord extérieur de ce verre. En outre, le mode de fixation plus spécialement adopté permet dans tous les cas la mise en oeuvre d'un enjoliveur extérieur au droit du tenon et venant se placer devant le verre, cet enjoliveur pouvant être facilement changé par l'utilisateur sans intervenir directement sur le tenon lui- même.A spectacle frame of new design is thus produced, in which each lens only has a through hole, allowing the mounting of the tenon carrying each of the lateral branches, without the need for any additional piece projecting or resting on the outer edge of this lens. In addition, the more specially adopted method of attachment allows in all cases the implementation of an external hubcap to the right of the post and coming to be placed in front of the glass, this hubcap can be easily changed by the user without directly intervening on the post itself.
Par ailleurs, l'ensemble des éléments de fixation décrit peut être réalisé en matière plastique, du genre « TEFLON »; de même on peut remplacer les enjoliveurs et clipser à leur place des verres colorés solaires, devant des verres incolores.Furthermore, all of the described fastening elements can be made of plastic, of the "TEFLON" type; similarly you can replace the hubcaps and clip in their place colored solar glasses, in front of colorless glasses.
Bien entendu, il va de soi que l'invention ne se limite pas aux exemples de réalisation plus spécialement décrits en
référence aux dessins annexés; elle en embrasse au contraire toutes les variantes.
Of course, it goes without saying that the invention is not limited to the embodiments more specifically described in reference to the accompanying drawings; on the contrary, it embraces all its variants.
