• Patent No. WO 99/05561 / PCT FR98 / 01613 describes a system for mounting the arms based on the molding of a relief (protuberance), 0 at the respective left and right ends of the corresponding glasses.
• Patent US4723844 recommends for the arms a system of two flexible wires, terminated however at the ears by semi-rigid plastic elements, shaped to hang on the front and rear of the 0 ears, following the curve and similar to the elements in "D" above.
• the essential problem posed by this configuration is not to immediately adapt to any face, because of the length of the wires which must be adjusted beforehand for each.
• the main aim of the invention is precisely to solve these problems. However, it aims much more, as mentioned above, and this is how it offers a whole new way of seeing and protecting oneself, with lightened, ventilated glasses, without obstruction of the visual field, and of a sought-after aesthetic, easily adaptable.
• the invention consists of the joining of two spectacle lenses, by means of at least one intermediate central bridge, the lenses being left free elsewhere, so that by a point fixing at their left and right ends, fixing which can be direct or indirect, by means of an intermediate piece, a cord is called to play on each side the role of a mounting arm by being provided at its free end a stop or stop in the form of a compact object in volume, the function of which is to insert itself above and behind the ear, between the latter and the head, so as to constitute there a point d 'anchor for the cord; the two cords thus formed have the function of exerting traction on the ends of the glasses, to press them towards the face; this function is achieved by an elastic arrangement of these two cords, achievable in special ways, supplemented by a possible pivoting of the plane of the lenses worn, around two supports formed on the vertical middle part of the frame bridge as follows: on the other side of the straight segment connecting the attachment points of the two cords on the lenses (line of traction): in the
• the essential characteristics of the invention thus consist in the abandonment of the usual system of arms and cords weighted with weights or pulled behind the ears by sliding rings, and their replacement by two flexible cords, with very light wearing and in contact pleasant, self-traction, requiring for their fixing on the glasses of simple points, so that the following results result from this design:
• a new process for dressing prescription glasses is constituted, and the products thus obtained, according to the invention, or according to certain of its methods of application and execution, to which it seems that there is reason to give the preferably, as follows: f or carrying out the invention, the procedure for example as follows, one in the component elements according to the following provisions:
• Figure 1 Plate I shows an overview of the pair of glasses with its cords and their stops
• Figure 2 Plate I shows the detail of a protuberance, also called upper bridge or abutment on the face
• Figure 3 Plate I shows a detail of the cord system with the stop and a possibility of adjustment of the latter by thread
• Figure 4 Plate I represents a detail of the cord system with the stopper and a possibility of elastic adjustment of the latter by spring
• Plate II represents a device for fixing the end of the cord to a glass by means of a screw flat head and a cap nut
• Figure 6 represents a different device for fixing the end of the bead to a glass, by means of a hook with welding
• Figure 7 Plate II represents a different device for fixing the end of the bead on a glass, by hollow crimped rivet
• Figure 8 Plate II represents a different device for fixing the end of the bead to a glass, with masking of the fixing from the outside.
• a pair of glasses is formed, according to this example, by first preparing the various components, and first of all the glasses (1), by making the fixing holes necessary for their meeting around the central bridge (2), which is a piece preferably monobloc, and which itself comprises either pads on the nose, relatively independent and adjustable, as a preferential arrangement, or extensions acting as office, made in the mass and therefore fixed.
• Other holes are made at the ends of the glasses, which will be used to fix the cords, and which, in a simplified version which is that of the example, consist of small rivets passing through the glasses from the outside (convex face) inwards, where they are stopped either by a washer or a circular spring (rod), or by a small nut, which complete immobilizing them.
• a shape such as a ring for example (11), in which the end of the cord is fixed, by simple bending and knot on itself or by sewing, gluing, crimping or other.
• This device is usefully supplemented according to the invention, by the constitution of the stops (stops) in a flexible material, such as synthetic rubber, or the like, which will have the double advantage of giving more security to the wearer in the event of a side impact ( in a vehicle for example), and to provide greater grip of this stop between the ear and the head (earhook).
• a flexible material such as synthetic rubber, or the like
• VARIANTS the invention, as well as the specific arrangement illustrated, are naturally capable of being designed in several variants, according to the needs, or according to the necessities of the practical realizations.
• a simple variant is that of replacing the cord with a chain which provides traction on the glasses.
• Another interesting variant consists of a combination of flexible parts and (semi) rigid parts for the cord.
• the latter will advantageously correspond to the specific parts going from the fixing on the glasses, to the rest on the ears: in fact, this part is called to be always taut and, moreover, it is most visible laterally, so that the he user may wish to highlight it, as well as the manufacturer, if it is made of valuable materials, or if it includes the mark of the latter: in this case we would simply keep the point fixation at the glasses, as before.
• Variants may concern the shape of the stops, and we essentially recommend for this element, two shapes: the first, a small sphere, and the second a cone (or truncated cone), whose common advantage is to adapt the better at their location behind the ear.
• the cone the preferred shape illustrated in Figure 4, is capable of an apex angle better suited to different physiologies, such as plated ears, or on the contrary detached.
• An important variant consists of the constitution of glasses with variable geometry, around the bridge which. to do this, will be made up of articulated central parts, which will be small nested friction parts, drawn in their center by a powerful spring, or elements nested by force, so that the natural friction of the materials maintain their relative immobilization .
• a simpler variant would consist in constituting the bridge in a deformable material.
• this variant is made possible particularly by the invention, since the use of current articulated arms does not allow an effective adjustment of the planes of the lenses around the eyes without significant alteration of the geometry of the frames. and without risk of embrittlement either of the glasses or of the other elements.
• the invention allows this central bending to provide better coverage of the eyes, the cord adjusting by nature. Thus, much greater comfort can be obtained.
• Ultra-compact variant The arrangement of the glasses according to the invention, without frame uniting the glasses, also allows, in the option of glasses with fixed or variable geometry, the possibility of having separable glasses, which is achievable simply by making fit and disengage at will two parts of the bridge connecting them.
• the glasses can be superimposed for storage needs in a case reduced in size by half, both for the length and for the thickness: thus, an additional compactness of the assembly can easily be obtained by making this case even a pendant, keychain element or other, within easy reach.
• a hollow rivet (12) mounted adjusted, by the face convex of the glass in a very small hole (of the order of a millimeter) and into which is inserted the simple end of a wire - notably metal - corresponding to the end of the cord to be connected; the wire is crimped into the rivet by pressure, or even welded with a very penetrating metal such as silver.
• the operation ends either by forcing the rivet thus connected to the cord, in the hole of the glass, or by the addition of a strong adhesive, which will result in sealing off the micro-cracks which have arisen in the latter.
• Another process suitable for the invention is that of surface chemical bonding, or hot bonding, which both, analogous although profoundly different, are made possible by the general concept, and result in a refined aesthetic of the together: they are practiced by relating the relatively wide base of a small part, directly on the optical glass, to its concave part, either by the interface of an adhesive, or by heat, a process used in plastics processing.
• the invention is not limited to the embodiments shown and illustrated. It covers the whole concept, explained herein, of new glasses, as well as the bridge with articulated curvature correction, as well as the hollow crimp rivet, as new products; the invention also covers the processes represented by the system for attaching and adhering the glasses, the system for point fixing directly by welding on the organic glass; it covers in particular the applications of adaptation to portable electronics; Finally, it covers, as new combinations, side cords associated with a lighting lamp, scientific or medical devices, detectors (types of gas, Geiger, luxmeter, etc.), without limitation.
• the invention covers all the systems which can use it essentially for their constitution or their adequate functioning, the tools necessary for its production, as well as all the combinations likely to employ its special characteristics to contribute to their own ends.
