FR2872925A1 - Safety and optical spectacles for e.g. correction of amblyopia, has frame horizontally cleaved at level of nose, where two parts of frame are connected by elastic line that assures fixation of glasses - Google Patents

Abstract

The spectacles have a frame (1) horizontally cleaved at a nose. The frame has housing at the nose to insert an elastic line (3) for assuring fixation of glasses (2). Two parts of the frame are connected by the elastic line that is located perpendicular to a slot of the spectacles. A part of the frame in contact with the line has a particular shape.

Description

Eyeglass frames with elastic nose.

  The present invention relates to spectacle frames with elastic nose.

  It concerns the industrial and commercial field of the manufacture and the diffusion of articles intended for the correction of the visual deficiencies or the protection of the eyes.

  Today, opticians are increasingly finding optical or sunglasses of all shapes and colors whose lenses are mounted and fixed in the workshop without any possibility of change by the user.

  Their usefulness makes these articles meet a significant commercial success. However, they have a number of disadvantages, and in particular The wearer is forced to always have the same frame with the assembled glasses, he can adapt his glasses to his activity (sport, work _), unless you have several pairs.

  - In case of breakage, it often takes several days to get parts, with a risk of losing the clamping screw for metal mounts.

  editing is often long and tedious and requires very careful intervention.

  The device according to the present invention eliminates all these disadvantages. Indeed, the nose of the frame is split horizontally and is connected by an elastic link which thanks to a small spacing by pulling on the edges of the frame allows the assembly and disassembly of the glass and its maintenance under tension when wearing glasses . The assembly is much simpler, the set is reliable because it can not disassemble itself.

  The mount (fl has a housing at the nose for inserting the elastic link (3) The wearer of these frames will have light glasses, comfortable, gene-free and with great reliability.

  Similarly, the frames can advantageously be proposed with different lengths of branches to allow to adapt the glasses to the majority of cases that may arise.

  There are several systems of frames exposed in the patents El '0361 547 A2, WO 92/08158, they always resort to devices to assemble the glasses relative to the mount.

  Other systems, such as that described in patent PCT / US95 / 03679, can only concern afocal systems and in no case correcting systems because they use cut or molded screens always having the same thickness.

  In addition, the glasses can be replaced independently very easily, in case of scratching, breakage or modification of visual impairment over time.

  Similarly, the frame can be changed at any time by its user, who can thus have several frames for a single set of glasses.

  The device consists of corrective or protective lenses (21 provided with a bevel of different shapes possible on their edge for mounting them quickly and easily on their support.

  The mount (1) is split horizontally and comprises a housing or is inserted the elastic link (3) so as to ensure the fixing of the glass, while allowing its removal without tools.

  In the accompanying drawings, given by way of nonlimiting examples of embodiment of the object of the invention. FIG. 1 represents in axonometric perspective a pair of glasses (2) assembled on the frame (1) and the elastic link. (3).

  Figure 2 is an enlargement of detail D of the previous figure in closed and open position.

  75. Figure 3 shows enlarged and exploded a glass (2) and the mount (1).

  The glasses (2) made of synthetic material, preferably of polycarbonate, trivex, organic or any other optical material on the market, are bevelled with different bevel shapes or slits (4). 65

  The frame (1) can be made by machining, cutting, welding, molding, or any other processes and dobbies used in the field of optics can be used (acetate, propionate, steel, monel, titanium, synthetic materials) The elastic link (3) can be made in various shapes or can be one or more wires having a suitable diameter of elastomer or other elastic material (rubber, synthetic products) or metal.

  The part of the frame (1) in contact with the elastic link (3) may have a particular shape to avoid the pivoting of the lenses (2). The elastic link may be positioned either at the nose or at the temples.

  The elastic link (3) can be fixed by an indeformable ring or can be an elastic O-ring.

  The elastic link (3) can be a single or double wire or two holes in the frame for mounting lenses and their positioning rigidly.

  The elastic yarn (3) is perpendicular to the face of the glasses W. The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not been, to date, obtained by similar devices.

  The eyeglass frame (1) is split horizontally at the level of the nose, the two parts of which are connected by an elastic link allowing easy mounting and dismantling of the corrective and / or protective lenses (2). The elastic link (3) can be either a machined, molded, cut piece or one or more elastic threads.

  The mount can be split at the nose or temple or any other place.

  The elastic link (3) is perpendicular to the slot of the glasses (1).

  The spectacle frame (i) is split at the level of the nose and / or tenons, the two parts of which are connected by one or more elastic threads allowing easy mounting and dismantling of corrective and / or protective glasses M whose corrective power from the view can be identical or not.

  The eyeglass frame (1) can be split at the nose or temple or anywhere in the bezel.

  The elastic link t3) may be a deformable ring or may be an elastic O-ring.

  The elastic link (3) can be doubled, either by a double wire or by two holes in the frame for mounting the glasses and their positioning rigidly.

  The elastic thread 3) can be perpendicular to the face of the glasses (1).
