Description

Bridge for auxiliary lens {Bridgc for support lens}

The present invention relates to mechanical means for attaching an auxiliary lens to glasses with its bridge.

Meeker, U. S. Patent No. 4,070, 103 discloses a spectacle frame having a unitary slideable rim. In the Meeker patent, the spectacle frame has a magnetic material fixed to the front face of the frame to facilitate attachment of the auxiliary frame. The lens rim cover also has a magnetic strip that engages with the magnetic material of the spectacle frame.

Other assistive eyewear attachments are US Pat. No. 5,416,537 to Sadler, US Pat. No. 5,737,054 to Chao, US Pat. Canadian Patent Application No. 2,236,025, Madison Canadian Application No. 2,223,088, Chao US Patent No. 5,568,207, Chao Canadian Patent No. 2,223,295, Karp German Patent Application DE 43 16 698, Zelman's PCT Application No. WO 026718, Canadian Patent Application No. 2,235,917 to Chao, US Patent No. 6,542,177 to Nishioka, and PCT Application WO 9009611 to Stemme. In all these cases, the auxiliary lens is attached to the frame by the magnetic material.

There are some drawbacks to using magnets to attach auxiliary lenses. The strength of the magnet weakens over time. Otherwise, the magnet attaching means is effective only for the selected metal frame unless the magnet is embedded in the spectacle frame.

This requires a cavity in the frame to engage the magnet member to compensate for the strength of the frame. There are also documents that suggest that magnets placed near an object can change the chemical or physiological properties of the object.

Ku's U. S. Patent No. 6,053, 611 discloses an auxiliary eyeglass having magnets located on upper and lower flanges extending rearward to the main bridge and also having upper and lower magnets corresponding to the magnets. It is difficult to insert four magnets into this limited space and therefore expensive. As also mentioned above, there are several other drawbacks associated with the use of magnets in glasses. As the strength of the magnet weakens, Ku's design will become ineffective.

One way to attach an auxiliary lens without a magnet, which attempts to solve this problem, is the ColorClip ^™ system. The system provides perforated holes at various locations around the outer circumference of the auxiliary lens. Then insert the soft plastic clip into this hole. A similar system, ECLIPS, requires the lens to be etched, coated with primer and adhesive, and relied on an auxiliary clip on the eyeglasses. In both systems the clips are combined with the goggles. Using these clip systems, it is easy to damage the field of view by damaging the various positions of the secondary lens, such as the upper, lower and side parts of the lens during drilling, scoring, gluing or attaching the clip. Each auxiliary lens must also be attached or removed from the mainframe separately. In use, the presence of a clip on the lens may obstruct the field of view. Many wearers also find the clips unsightly or unattractive.

It is therefore an object of the present invention to provide a means for attaching an auxiliary lens to a goggle without relying on a magnet and without having to replace a clip on the lens.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which like elements are denoted by like reference numerals.

As shown in FIG. 1, the spectacle device of the present invention has an auxiliary bridge 60 for detachably attaching to the main frame 32. 1 shows an exploded form of the device with the auxiliary lens removed to better show the details of the secondary bridge 60.

The mainframe 32 is configured to be worn on the wearer's head by a leg 44 fitted to the wearer's ear to support the glasses. The mainframe 32 has a bridge 34 with a ridge 36. Ridge 36 has a ridge front face 38 and recesses 40. There must be at least one recess 40 for the effective operation of the device. In the illustrated embodiment there are two recesses 40, one of which is above the ridge and one at the bottom. Ridge portion 36 and concave portion 40 is configured to be detachably coupled to the secondary bridge (60).

The auxiliary bridge 60 has an upper protrusion 62 and a lower protrusion 64. At least one of the protrusions 62, 64 has a protrusion 66 configured to be detachably coupled to the recess 40. In the illustrated embodiment there are two projections 66, one on top of the ridge and one on the bottom.

In FIG. 2, the main frame 32 includes a main bridge 34 extending between the main lenses 18 in the middle between the frames and connecting the main lenses. The main frame 32 provides a structure for holding the main lens 18. The main lens 18 may be transparent or slightly colored glass or plastic. One or two of the main lenses 18 can be tailored to the visual defect of the wearer.

The auxiliary glasses 20 are united when assembled. The auxiliary lens 50 is configured to cover both main lenses 18. The external shape of the auxiliary lens 50 generally coincides with the external shape of the main lens 18. One use of the auxiliary lens 50 is to protect the wearer from sunlight and other visual impairment elements. Therefore, the auxiliary lens 50 may be colored and may have or be coated with a material for filtering ultraviolet light or other specific wavelengths of light.

The auxiliary glasses 20 consist of an auxiliary bridge 60 which provides a means for holding the auxiliary lens 50. As shown in FIG. 1, the secondary bridge 60 has a rivet 72 ending with a spherical portion 74. When assembled, the lens rivet 72 extends horizontally through the aperture of the lens 50. The lens rivet 72 ends with a spherical portion 74. The spherical portion 74 allows the lens 50 to be securely attached to the secondary bridge 60. The spherical portion 74 may be provided during the assembling of the lens 50 to the auxiliary bridge 60, or may be formed or partially deformed at the time of assembly to increase attachment safety.

The secondary bridge 60 may be made of any flexible material having plastic memory characteristics. In one embodiment of the present invention, the auxiliary bridge 60 may be made of Polyflex ^™ (Hyundai, Incheon, Korea) or memory plastic. Memory plastic and Polyflex ^™ are lightweight plastics that can be bent or stretched without losing their original shape. Polyflex ^™ is particularly elastic in this respect. Using such a material, it is possible to repeatedly use the clip device between the secondary bridge 60 and the main bridge 34 without deforming the shape or deteriorating the attachment safety. This material is also particularly suitable for mechanically assembling the auxiliary bridge 60 and the auxiliary lens 50.

As shown in FIG. 4, the lens rivet 72 is inserted through the hole 52 of each lens at the time of assembling the auxiliary bridge 60 and the auxiliary lens 50. Polyflex or memory plastics can be inserted without damaging the lens. The spherical portion 74 is configured to have a larger diameter than the hole 52 when not deformed. With this material, the spherical portion 74 can be inserted through the hole 52 by the temporary deformation of the spherical portion 74. When inserted through the hole 52, the spherical portion 74 can restore the original diameter by the plastic memory characteristics to secure the lens 50 to the secondary bridge 60 by interference coupling. After assembly, the spherical portion 74 is treated with an adhesive or other fixing agent, or the spherical portion 74 is treated with a compressive force sufficient to permanently deform the spherical portion 74, and the rear surface or the lens around the hole 52 is adjacent. By spreading on the surface, adhesion safety can be improved.

As shown in FIG. 1, the main bridge 34 has a ridge front surface 38 that tightly engages with the auxiliary bridge surface 70 when the auxiliary bridge is assembled with the goggles. This tight engagement prevents the bridge from rotating when the wearer uses the assembled device of the present invention during intense activity, rotating about its vertical axis.

As shown in FIG. 2, the ridge front face 38 extends in parallel and forms a tight coupling with the auxiliary bridge surface 70, which also extends in parallel when the auxiliary bridge is assembled with the goggles. This tight coupling also prevents the bridge from rotating when the wearer uses the assembled device of the present invention during intense activity, rotating about its vertical axis.

1 and 2, the main bridge 34 has a ridge vertical surface 38 that tightly engages the protruding surface 68 when the secondary bridge is assembled with the goggles. This tight engagement prevents the bridge from rotating when the wearer uses the assembled device of the present invention during intense activity, rotating about its vertical axis. 3 and 5, the shape of the main bridge 34 has a curved portion, which coincides with the curved portion of the shape of the auxiliary bridge 60. When assembled, these corresponding curves are tightly coupled to prevent the bridge from rotating off the horizontal axis.

As best shown in FIG. 2, the projection 66 (shown in dashed lines as being on the underside of the projection 62) extends longitudinally along the recess 40. Therefore, when the auxiliary bridge is assembled with the goggles, the projection 66 is tightly coupled with the recess 40. This tight coupling prevents the bridge from rotating away from its vertical axis. Thus, the mechanical clamping of the protrusion / concave system of the present invention provides excellent mating safety for all axes which were not possible in the prior art.

1, 2 and 5, the main bridge 34 is configured to be physically obstructed by the shape of the main bridge 34 corresponding to the auxiliary bridge 60. This obstruction is not only made in the horizontal direction, that is, the interference between the main bridge 34 and the auxiliary bridge 60 not only prevents the auxiliary glasses from moving downward, but also in the vertical direction. Accordingly, the auxiliary glasses 20 and the main frame 32 are more firmly attached to each other.

Due to the multiple interference coupling between the secondary bridge and the main bridge described herein, the auxiliary glasses 20 may not easily collide with the main lens 18 during physical activity. This prevents annoying rattling noises between the secondary eyeglasses 20 and the primary eyeglasses 42 and reduces the contact between the main lens 18 and the secondary eyeglasses 20 to reduce the risk of scratches or other lens damage. Reduce In addition, the risk of accidentally peeling off the eyeglasses is greatly reduced. Other known devices would not be able to separate the secondary eyeglasses of the present invention from the main eyeglasses because of the multiple interference couplings of the invention described herein.

When the fixing device of the present invention is combined, since the auxiliary lens 50 is positioned adjacent to the main lens 18, a minimum amount of light enters between the lenses.

Since the protrusions 62 and 64 and the ridges 36 extend outward from each frame, no recesses to weaken the frame are required in the frame. Also, since no recesses are used in the fixture, they can be easily removed and replaced in the goggles without bending or bending the frame or bridge and without engaging the auxiliary glasses 20 at difficult angles with respect to the mainframe 32. Secondary glasses are provided.

In the illustrated embodiment, the projection 66 is inclined. Inclined projections make it easier to attach and remove the secondary glasses.

Accordingly, it will be appreciated that the present invention provides a method for firmly attaching secondary eyewear to the primary eyeglasses without degrading the ease of removing and replacing the secondary eyewear. Removal and replacement can be done with one hand without difficult handling and disengaging angles.

In contrast to magnetic means, the use of mechanical attachment means provides a significant advantage. First, in manufacturing the device, the auxiliary bridge and the main frame are cast with a desired material and then ready for assembly. No drilling or drilling is required to make holes for insertion of the magnet. There is no need for magnets or other additional parts, nor for the fixing of mounting means. Since the attachment device of the present invention is a "one-piece" design, the device will not loose or fall out over time and with the influence of climate due to temperature and humidity changes.

Another advantage of the means of the present invention for attaching the auxiliary bridge to the auxiliary lens is that no lens frame is required for the auxiliary lens, thus reducing the weight of the auxiliary glasses and reducing the manufacturing cost of the auxiliary glasses.

The above detailed description with reference to the drawings is to be regarded as illustrative and not restrictive. Modifications and variations of the embodiments described above can be made within the scope of the present invention. For example, the auxiliary lens 50 may also be used to improve vision. In this case, the auxiliary lens 50 may be made in the same manner as the magnifying glass and fitted to the main lens 18, which may or may not be a prescription lens. To reduce fatigue of the wearer's vision, the auxiliary lens 50 will magnify small or complex details for better viewing. The auxiliary lens 50 may also have a decoration that will be seen by a person viewing the wearer to improve the appearance of the lens or for entertainment purposes.

In another embodiment, the present invention also contemplates eye glasses that do not have a main lens 18. This embodiment would be useful if the user wishes to remove and replace the auxiliary lens 50 but does not need the main lens 18 to aid vision. For example, this embodiment would be useful in welding environments where a very dark lens is required during welding but no lens between welding operations is desired. As another example, a person with visual impairments that are difficult to read would preferably have no lens except when reading.

In the illustrated embodiment, the side shapes of the protrusions 62, 64 and the corresponding side shapes of the ridges 36 prevent the horizontal movement of the assembled device. However, in another embodiment (not shown), the horizontal movement can be prevented by providing two protrusions 62 and 64 spaced laterally and corresponding to the ridges 36.

As shown in FIGS. 1, 2 and 5, the main bridge 34 has at least one recess 40 in the ridge 36. In the illustrated embodiment, the recess 40 is observed at the top and bottom of the ridge 36. In other embodiments (not shown), only one recess 40 may be present. In another embodiment (not shown), the single recess 40 may be comprised of a hole extending vertically through the ridge 36.

It is to be understood that only preferred embodiments are shown herein and that modifications will be readily apparent to those skilled in the art. Therefore, the true scope and spirit of the present invention are intended to be included within the scope of the appended claims and their legal equivalents rather than the embodiments set forth above.
