Definitions
- the present invention relates to eyewear and, more specifically, to a fastener for glasses of eyewear.
- the fitting of glasses for eyewear is done, in a traditional way, according to two different techniques.
- each lens is encased in a ring, called a circle, which belongs to a frame comprising, moreover, a bridge connecting the two circles, two nose pads and two branches each associated with a circle.
- the fixing by drilling of the glasses has the disadvantage that in the drilling area, the glass is mechanically weakened and may break. This risk is all the more present and increased since, with use and over time, the screws gradually loosen themselves and the glass can therefore be broken, either when a screw is tightened or makes relative movements of the glass and the fastener when there is a certain freedom between them.
- the invention relates to this second mounting technique, and it aims to eliminate the drawbacks mentioned above.
- the glass fastener according to the invention for eyewear, intended to be mounted on a glass having two faces and a peripheral edge, is characterized in that it is constituted by a piece U-shaped elastic forming a clamp, the central core of which is intended to overlap the edge of the glass and the branches of which are intended to come to bear respectively on the faces of the glass in order to tighten them elastically.
- connection of the glass with at least one other element of the eyewear is done by simple elastic mechanical pinching of the glass, in the vicinity of its peripheral edge. This allows in particular an easy installation and removal of the fastener relative to the glass, in particular without weakening the mechanical strength of the latter.
- the fastener can be of any suitable material, for example metal, in particular spring steel, or plastic.
- the central core of the U can be in contact or without contact with this edge.
- At least one of the branches of the U is planar.
- at least one of the branches of the U has, in cross section, a convex shape whose concavity is turned towards the face of the glass with which it cooperates.
- at least one of the branches of the U has, at its free end, a ramp to facilitate mounting of the fastener on the glass.
- the flat branch of the U is then intended to cooperate with a concave face of the glass, while the convex branch of the U is intended to cooperate with a convex face of this glass.
- the fastener comprises a protuberance which extends from its bottom over approximately one third of its length and which partially joins the faces facing the branches.
- the width of this protuberance may be less than or equal to the width of the fastener.
- the fastener according to the invention is integral with at least one other element of the eyewear, either by being in one piece with this element, or by being attached to it, in a fixed or adjustable manner.
- This element is for example a branch of glasses, a bridge connecting two glasses, a nose pad or even a bent tab for the removable mounting of a solar adapter on glasses.
- the present invention therefore also relates to an eyewear article of the pair of glasses type without a circle, characterized in that it consists of two glasses and four fasteners, two exterior and two interior, each exterior attachment being associated with the one of the branches of the pair of glasses and each interior clip being associated either with one of the two ends of the bridge connecting the two glasses, or with a nose pad.
- a third object of the present invention is an eyewear article of the removable solar adapter type, characterized in that it consists of two glasses and four fasteners, two upper and two lower, in that each fastener comprises a tab which s extends perpendicularly to the branches of the fastener, from the back of the core thereof, and in that the two upper fasteners are connected by a connecting bar, thin and flexible, one of said fasteners being secured to the bar while the other fastener is adjustable in position on the bar, for example by means of a screw, in order to define the useful length of the bar.
- the present invention has for its fourth object an eyewear article of the removable solar adapter type, characterized in that it consists of two glasses and four fasteners, two upper lateral and two lower lateral, in that each fastener comprises a tab which extends perpendicular to the branches of the fastener, from the back of the web of the latter, and in that the two upper lateral fasteners are connected by a flexible nasal bridge.
- the present invention has as its fifth object an eyewear article of the individual and removable solar glass type, characterized in that said glass comprises three fasteners, each of such fasteners having a tab which extends perpendicularly to the branches of the fastener from the back of its soul.
- each of the lenses of each of the aforesaid eyewear then has a notch which extends from the periphery of said lens.
- FIG. 1 is a cross section of part of a glass of an eyewear article carrying a fastener according to a preferred embodiment of the invention
- FIG. 2 is a perspective view showing glasses with fasteners according to the invention.
- FIG. 3 is a perspective view showing a solar adapter fitted with fasteners according to the invention
- - Figure 4 is a cross section of an alternative attachment allowing the mounting of a solar adapter on an existing mount.
- FIGS. 5 and 6 are views, respectively from the front with partial cutaway and according to section VI-VI, of another variant of attachment according to the invention, the bottom of which is provided with a protuberance capable of cooperating with a congruent notch formed at the periphery of the glass;
- FIG. 7 is a front view with partial cutaway of another variant of the fastener according to the invention, the bottom is provided with a wider protrusion, the same width as that of the fastener;
- FIG. 8 is a front view of a variant of a simplified solar adapter fitted with fasteners according to the invention.
- FIG. 9 is a front view of two sunglasses both fitted with fasteners according to the invention, which allow their individual mounting on each of the lenses of an existing frame.
- FIG. 1 a glass 1, for example belonging to glasses 2 ( Figure 2), a removable solar adapter 3 (Figure 3), another form of removable solar adapter 19 ( Figure 8) or constituting by itself a removable solar glass 1 or 1 "(FIG. 9).
- the glass 1 has two faces 4 and 5 and a peripheral edge 6. In general, the glass 1 is curved, its rear face 4 being concave, while its front face 5 is convex.
- the glass 1 is equipped with at least one fastener 7 which is constituted by an elastic U-shaped piece forming a clamp, whose central core 8 is intended to overlap the edge 6 of the glass 1 and whose two lateral branches 9 and 10, bordering the central core 8, are intended to come to bear respectively on the faces 4 and 5 of the glass to tighten them elastically and thus ensure the firm elastic mounting of the fastener 7 on the glass.
- at least one fastener 7 which is constituted by an elastic U-shaped piece forming a clamp, whose central core 8 is intended to overlap the edge 6 of the glass 1 and whose two lateral branches 9 and 10, bordering the central core 8, are intended to come to bear respectively on the faces 4 and 5 of the glass to tighten them elastically and thus ensure the firm elastic mounting of the fastener 7 on the glass.
- the shortest distance between the branches 9 and 10 of the U is less than the thickness of the glass so that, during mounting of the clip on the glass, the branches 9 and 10 are spaced apart elastically to ensure their function as a clamp.
- the fastener 7 is made of any suitable material, for example metal, and in particular spring steel, but it is not excluded to use another suitable material, for example a plastic material having satisfactory mechanical properties as to its resistance and its elasticity. According in particular to the shape which is given to the central core 8 of the U, the bottom 22 of the latter is in contact with the edge 6 of the glass, or without contact with it.
- the fastener 7 can be given any suitable shape in cross section, in particular for aesthetic reasons, provided that it can perform its clamp function without mechanically degrading the glass 1.
- a basic shape can consist of a U whose core and lateral branches are planar.
- the inner or rear branch 9 that is to say the one which presses on the rear face 4 of the glass
- the outer or front branch 10 cooperating with the face front 5 of the glass
- the free end 10a of the branch 10 advantageously has an inverted concavity defining a sliding ramp on the face 5, during the mounting of the fastener on the glass 1, this ramp facilitating the separation of the branches 9 and 10 during assembly and avoiding scratching the glass.
- the fastener 7 according to the invention is intended to be integral with at least one other element of the eyewear item, by being, as the case may be, in one piece with it or attached fixed or adjustable on it.
- each lens 1 of the glasses 2 carries two fasteners 7 which are mounted at the ends of the upper part of the edge 6.
- Each external fastener 7 carries a branch of glasses 11, by means of a hinge 12, while the internal fasteners 7 fixedly carry a bridge 13 for connecting the two glasses.
- the internal fasteners 7 can also carry nose pads or, alternatively, platelets can be carried by two other fasteners according to the invention.
- each glass 1 of the removable solar adapter 3 carries two fasteners 7.
- Each glass 1 has been previously cut, or chosen to be identical, to the shape of the glass 1 which corresponds to it on the pair of glasses 2, when the lenses are not encircled, or in the shape of the circle which corresponds to it on the pair of glasses in the particular case where the lenses thereof are encased in a frame with circles.
- each of the four fasteners 7 integrally carries a lug 14 for the removable mounting of the adapter 3 on a pair of glasses such as that which is for example shown in FIG. 2, or another classic pair of glasses, with encircled or non-encircled lenses.
- each tab 14 From the back of the core 8 of the clip 7, each tab 14 first extends perpendicularly to the branches 9 and 10 of the clip, then it is bent at about 90 degrees so as to be parallel to the branches 9 and 10 and to be oriented in the same direction as said branches so as to be able to overlap the edge 6 of the corresponding glass 1 of the pair of glasses 2 by hanging on this glass, in the example shown in FIG. 2, or in order to be able to overlap the corresponding circle with a pair of rimmed glasses, in the other case where the lenses of the glasses are set in circles.
- each tab 14 receives a tubular sheath 25 of plastic material (shown in dotted lines in FIG. 4) intended to protect the lenses and / or the circles of the frame which will receive the adapter 3.
- each lens 1 of the adapter has a clip 7 at the outer end of the lower edge of the lens and a clip 7 at the outer end of the edge glass top.
- the upper fasteners 7 are connected by a connecting bar 15, thin and flexible, for example metallic, the length of which allows, by bending this bar, to separate the two glasses sufficiently from one another, and therefore the two lower tabs 14 from one another, to allow the adapter to be fitted and removed on the pair of glasses 2.
- one of the ends of the bar 15, for example the left end in the drawing, can be secured, for example by welding, to one of the upper fasteners 7, while its other end (that of right in the drawing) can slide in an adjustable manner, relative to the other upper fastener 7, for adjusting the useful length of this bar.
- the right fastener is then provided with a boss 16 of generally cylindrical shape which is welded to the core 8 of the fastener 7. This boss is pierced with an orifice 17 for passage with a very slight play of the bar 15.
- the bar 15 is immobilized relative to this second fastener 7, for example by tightening d 'a screw 18 whose threaded rod 23 cooperates with a tarand hole 24 drilled perpendicular to the core 8 of the fastener 7 and to the direction in which the bar 15 crosses the orifice 17 of the boss 16. After this immobilization, the bar 15 is cut slightly beyond the right fastener.
- each glass 1 of the removable solar adapter 19 carries two fasteners 7, an upper side and a lower side.
- Each of these fasteners is of the type described above, that is to say of the fastener provided with a lug 14 which allows the removable mounting of the adapter 19 on a pair of glasses such as that shown in FIG. 2, or even on a classic pair of glasses.
- Each of the two aforementioned upper lateral attachments is fixedly disposed at one of the two ends of a nasal bridge 13 made of a very elastic material, for example spring steel, and the length of which is chosen so that, because of the great flexibility of the bridge 13, the adapter 19 can be mounted and held resiliently on the pair of glasses to be fitted, overlapping either the two glasses 1, in the case where these are not surrounded, or the circles in the case where the spectacle lenses are set.
- the two lower lateral attachments substantially diametrically opposite the upper attachments, ensure perfect attachment of the adapter 19 on the pair of glasses to be fitted.
- the solar glasses 1 'and 1 are individual and are each provided with three fasteners 7 also each provided with a lug 14 which allows independent hanging of each solar glass 1' and 1 "on the pair of glasses to be fitted, whether the glasses are encircled or not encircled.
- This variant eliminates the flexible connecting bar 15 of the adapter 3 or the flexible nasal bridge 13 of the adapter 19.
- the protrusion 20 therefore partially joins the two faces with respect to the branches 9 and 10 of the fastener 7.
- the protrusion 20 may be of a width less than the width of the fastener 7 ( Figures 5 and 6) or equal to that of the fastener 7 ( Figure 7).
- the notch 21 is also appreciably less wide than the fastener 7 and, in this case, said notch is invisible under the fastener 7 after its installation on glass 1, l or 1 ". If the protuberance 20 is of a width equal to that of the fastener 7 ( Figure 7), it is barely visible on either side of said fastener when the latter is placed on the glass 1, l 'or 1 ".
- This notch arrangement 21 - protuberance 20 has the advantage of preventing the fastener 7 from being able to pivot on the glass 1 after it has been mounted on the said glass and, consequently, that it tends to detach from it, whatever the width of the protrusion relative to the width of the fastener
