FR2845490A1 - System for supporting glasses comprises four arms of single metal structure placed on nose, arm ends having flexible parts exerting pressure on each side of face - Google Patents

Abstract

The system for supporting one or more glass lenses is assured by four arms (2,2',3,3') of a single metal structure (1) placed on the nose. The arm ends are provided with flexible parts (5a,5a',5b,5b') which exert a pressure on each side of the face.

Description

The present invention relates generally to the field of

  eyewear and more particularly a system for maintaining glasses. S The holding of a frame of glasses on the face is usually obtained with the help of two branches coming to lodge on and behind the ears as well as two plates supporting the mount -on the nose. The branches are generally hinged to the respective outer ends of the glasses. This traditional system offers comfort and maintenance sufficient for normal activity (reading, driving ...), but it remains ill suited to 15 assumptions where the wearer is required to execute fast movements or to adopt reversed positions. . Indeed the mount is placed on the nose and ears and the ends of the branches located behind 'The ears have the function of holding the mount in place. When the traditional mount is in a position where the force of gravity is no longer parallel to the vertical axis of the face or in circumstances where this gravitational force is coupled with one or more other forces (race).

  on foot, jump ... the mount can lift and come off the face. The traditional mount therefore prevents the horizontal movement of the mount on the face, but not its vertical movement from bottom to top.

  The object of the present invention is to overcome this disadvantage by preventing the vertical movement of the frame in addition to the horizontal movement. It thus makes it possible to prevent both the horizontal movement and the vertical movement of

Frame.

  The system achieves this objective with the aid of a unique metal structure placed on the nose, -2 which is held by pressure on each side of the face on the areas of the temporomaxillary joint and fronto-parietal. More precisely, the system distributes this pressure using four legs. The distribution of this pressure is realized

  between two lower legs and two upper legs that adhere respectively to the temporomaxillaries and fronto10 parietal areas on each side of the face.

  The zone of the temporomaxillary joint is painless and forms a slight boss on the face, which allows the lower legs to be housed behind this boss with sufficient pressure to maintain the frame without

  cause embarrassment to the wearer of the mount.

  The fronto-parietal zone is more sensitive,

  it is just above the temporal bone.

  The pressure exerted by the upper legs is less than that exerted by the lower legs. The function of these legs, the stability of the frame on the face, also requires less pressure force than maintenance. Indeed, the stability is ensured by the adhesion of the ends of the upper legs on the face by preventing the mount from tilting vertically on

the top of the face.

  The lower tabs keep the system on the face by preventing horizontal movement of the mount, and the upper tabs provide stability of the entire system on the face by preventing vertical movement of the mount. The pressure necessary to maintain the frame is obtained thanks to the flexibility of the structure. The flexibility of the structure is inherent to the quality of the material that composes it. It may be made of stainless steel or any other material having similar flexibility characteristics. It thus makes it possible to adapt the frame to the morphology of the face. The said system can therefore adapt to different facial morphologies. This pressure is manually adjustable

  folding the legs inward or outward.

  It is also possible to use a pliers or a tool to perform this operation In addition to the central structure and its four legs, the system is composed of two tray doors and their respective plate. The glasses are fixed on the central part. Pieces of flexible material are located at the ends of each leg to provide greater comfort to

  its carrier and better grip.

  It is possible to envisage a collapsible version of the product with a hinge located in the center of the frame or in another version a hinge on each of the four legs. One can also consider a version of the product with

retractable legs.

  The invention will be better understood when reading

  of the description of two nonlimiting examples of embodiment, with reference to the attached drawings o:

  Figure 1 shows a perspective view

  of a version of the present invention.

  Figure 2 shows a perspective view

  of this version of the present invention when worn on a face.

  FIG. 3 represents a detail view, seen from above of a leg end and of the device for attaching the flexible parts to the

metallic structure.

  FIG. 4 represents a detail view, seen from above of the lens fixing device

on the mount.

  Figure 5 shows a perspective view

  of another version of the present invention.

  With reference to these drawings, the device comprises a single metal structure (1). This structure is composed of four tabs (2, 2 ', 3, 3') whose ends are provided with flexible ends (5a, 5b, Sa ', 5b') inserted in openings provided for this purpose on these four said ends of legs, two platelet carriers (6, 6 ') provided with platelets (7, 7') inserted in openings 10 provided for this purpose on said so-called platelet carriers, and two glasses (4, 4 '). ) fixed on the said structure

  unique metal by screws (8a, Sa ', 8b, 8b').

  This metal structure follows the shape of the face. The lower legs (2 and 2 ') exert pressure on the area of the temporomaxillary joint (16) on each side of the face. The effects of discomfort that may be caused by this pressure are mitigated by flexible plastic tips (Sa, Sa ', 5b, Sb') whose inner part (18> is in contact with the face. ') are fixed on the central part of the metal structure (1) - The curvature of the metal structure (1) having a radius less than the camber of the glasses (4,4'), the outer end 25 of the glasses (4) , 4 ') is then at a sufficient distance from the metal structure (1) so that, when the assembly is worn on the face, the metal structure (1) adapts to the shape of the face without exerting pressure on the outer end of the glasses (4,4 ') The glasses (4,4')

  do not experience tension. In addition, they are fixed on the central part of the metal structure which is designed not to deform.

  The glasses thus maintain a stable position when the tabs are apart.

  The flexible plastic tips (Sa, Sa ', b, 5bf) are attached to said single metal structure (1) by fitting into an opening provided for this purpose. The said end pieces (5a, 5a ', 5b, 5b') comprise an inner part (18), an outer part (17) and a central part (19). To thread the flexible plastic tips (5a, 5a ', 5b, 5b') into the metal structure (1), the outer part (17) is forcefully inserted into the opening of the metal structure (1) until it comes out on the other side of the said metal structure (1). When the inner part 10 of the piece (18) is in contact with the metal structure (1) and the outer part (17) is out of the opposite side of the metal structure (1), the end pieces (Sa, Sa ', 5b, 5b') are

  then attached to the metal structure (1).

  The glasses (4, 4 ') are fixed to the metal structure (1) by means of a screw (8) and a nut (14). A plastic chimney (9) is placed in an opening on the glass and provided for this purpose. The screw (8) is introduced into this chimney (9). A first washer (11) is threaded

  on the threaded part of the screw to the glass.

  The assembly is introduced into the opening on the metal structure (1) provided for this purpose.

  A second washer (13) is threaded onto the threaded portion of the screw to the metal structure

  (1). A nut (14) is tightened on the end of the threaded portion of the screw. The two washers (11 and 13) and the chimney (9) serve to limit the fragility of the glass (4) when it is fixed on the metal structure (1).

  A second version of the present invention is shown in FIG. 5. Each of the stated principles that apply to the version of FIG. 1 also applies to this second version of FIG. 5. Its particularity is that each of the two pairs of lateral legs is

from the same branch.
