Description

Glasses structure for attaching an auxiliary lens {The glasses achitecture to keep the sub lens}

The present invention relates to a fastening assembly capable of attaching to an eyeglass an auxiliary lens that acts as a filter or protective shield or magnifying glass in a limited accessory area of the lens. This fastening assembly includes a mechanical retainer that can position and align the auxiliary lens and maintain this alignment. For example, the dentist must wear a protective shield to prevent radiation from the ultraviolet treatment device from being applied directly to the eye. UV protection shields secured by dental aids are inconvenient to use. In addition to such ultraviolet radiation, protection must be provided against ophthalmologically harmful radiation. Moreover, this separate auxiliary lens can also serve as a filter that can detect any object more clearly.

On the other hand, it is desirable to provide the eyeglasses with an enlarged accessory area so that they can be used for precision work requiring frequent magnification. Special bifocal lenses manufactured for this purpose are expensive.

The fastening assembly of the present invention can be used to fasten binocular loupes to spectacles, the fastening assembly comprising an attachment frame and two small magnifying glasses, each of which has at least two lenses. Provided, the eyepiece arranged closer to the eye of the two lenses is smaller than the outer objective lens. This small binocular magnifier attached to the glasses is intended to facilitate precise work, such as the work of a dentist or precision mechanic. A drawback of the prior art binocular magnifiers is that they contain complex shapes and excess weight, as well as limited field of vision.

U. S. Patent No. 5,182, 588 contemplates attaching a protective coating to the surface of such lenses in a limited subregion of the spectacle lens. Such thin surface coatings are not only difficult to manufacture, but also permanently change the spectacles, so this dissolution action is not suitable for the various spectacles that are controlled for each human eye. Moreover, the coating formed by the thin layer is difficult to provide a sufficient protective effect when clear transparency is required at the same time. These coatings are for protection only and do not offer the possibility of simultaneous or selective use of magnifiers or binoculars.

On the other hand, for example, U. S. Patent Nos. 4,647, 165 and 3,446, 548 disclose a configuration in which various auxiliary lenses are installed in an accessory region of the lens by mechanically adjustable arms. These prior art methods do not provide a reliable attachment to the auxiliary lens, and this arrangement of attachments is not suitable for all types of glasses. Typically the attachment is fixed by making specially designed eyeglasses, which incurs significant costs. The most common drawback of prior art attachment mechanisms based on mechanical attachment arms is that such attachment assemblies obstruct the field of view.

Referring to FIG. 1, the auxiliary lenses 4 are provided on the inner surfaces of both lenses 1 of the glasses, respectively, at positions close to the lower edges of the lenses 1, which are protected from harmful radiation. Acts as a protective means, magnifying glass or filter. The auxiliary lens 4 is attached by an elastic flexible arm 5 made of steel wire, for example. Both lower ends of this arm 5 are fixed by an adhesive provided into a slot-shaped groove formed at the lower edge of the auxiliary lens 4. Both upper ends of the arm 5 are fixed to a metal clip 6 which can be tightened by screws 7. This metal clip 6 is coupled with a connecting portion 3 which crosses the nose and connects the edges of the lenses 1 or the spectacle frame 2 to each other. The metal clip 6 comprises two body members 8, 9, which fasten the ends of both arms 5 between the bodies by tightening the screws 7. It is for. A locking ring 10 made of a flexible, soft metal, for example silver, provides a gripping yoke around the connection 3. Both ends of the fixing ring portion 10 are accommodated in the holes 11a and 11b penetrating through the body members 9 and 8, and the size of these holes 11a and 11b is that the helix of the screw 7 is the fixing ring portion. In proportion to the screw (7) to be able to engage with the material of (10). The fixed ring portion 10 may be provided with a spiral in a conventional manner, or the screw 7 may be cut to provide such a spiral. In the clip assembly thus configured, a single screw 7 can be used to securely clip the clip 6 to the connecting portion 3 and to engage the arm 5 with the clip 6. The surface facing the other body member 9 of one body member 8 is provided with a groove 12 of a depth smaller than the diameter of the arm 5 to receive the arm 5. Thus, the alignment of the arms 5 can be maintained, and the length of the arms 5 is adjusted by adjusting the arms 5 longitudinally between the body members 8, 9 before the screws 7 are tightened. Therefore, the auxiliary lens 4 can be installed at an appropriate position. Finally, a portion corresponding to the remaining length can be cut from both upper ends of the arm 5. If the arm 5 cannot be fixed from below, the fixing of this arm can be performed from above by bending the arm extending from the upper edge of the clip 6 downward.

In addition, the body member 8 of the clip 6 is configured to engage with a yoke shaped retaining portion 14 mounted on a base of an arm 15 that supports a separate magnifying glass or protective lens 16. . This yoke-shaped retaining portion 14 is engaged with the groove 13 while being pressed from the top onto the upper portion of the body member 8 by a rib included in the inner surface of the retaining portion 14. do. Magnifying glasses 16 of this type combined with spectacles are known in the prior art, but according to the present invention, these magnifiers or protective lenses 16 are provided in a new way by the retaining portion 14 in the form of a yoke. Is attached to the clip 6.

FIG. 2 shows this in more detail, with a protective lens 4b at the bottom of the auxiliary lens 4 and a magnifier 4a at the top. In this case, a separate magnifying glass 16 is not necessary. Alternatively, it is a matter of course that any one of the magnifying glass 4a, 16 may be composed of a filter or a combination of the filter and the magnifying glass.

Next, another preferred embodiment of the present invention will be described with reference to FIGS. 7 to 10. Referring to FIG. 7, the binocular type magnifier 18 is fixed to the connecting portion 3 of the glasses, which extends across the nose by the bracket 17. Each small magnifying glass 18 is fitted with at least two lenses, each of which has a smaller eyepiece closer to the eye than the outer alternative lens. On the outer surface of the miniature magnifying glass 18, a jacket 19 is provided which connects these two lenses to each other, which jacket 19 extends obliquely at a dividing angle which matches the angle from the eye to the edge of the eyepiece. have. Thus, the limitation of the field of view due to this small magnifying glass 18 is minimized. The user can observe the object through the small magnifying glass according to the present invention by turning the clock and the head slightly. The jacket 19 of the small magnifying glass may be configured in the form of a tube having a conical shape that matches the thin wall thickness and the angle of division. The jacket 19 may be made of metal, fiber reinforced plastic, or the like. Further, the cross section of the jacket 19 may be of circular, oval or polygonal shape. The miniature magnifying glass 18 is mounted on a flat transverse arm 20 which can be bent at the hinge point 21, This lateral arm 20 is made of metal and has a shape that changes due to bending. The hinge point 21 may be made of a different material than the lateral arm 20, for example a wire thread (20) to be inserted into the lateral arm 20 made of light metal or fiber reinforced plastic. wire threads). The axial direction of the hinge point 21 is selected to control the bending of the lateral arm 20, ie the axes of these hinge points 20 at different positions of the miniature magnifier 18 are essentially the same from the miniature magnifier 18. It is configured to intersect each other in distance. Thus, the small magnifying glass 18 can always be kept in focus under the condition that the distance between both small magnifying glasses 18 is set according to the distance between both eyes. At the intermediate point between the two hinge points 21, the two transverse arms 20 are connected to each other by longitudinal arms 24, which are likewise made of elastic metal at the attachment points of the longitudinal arms 24. The hinge portion 22 is provided. The longitudinal arm 24 is provided with a longitudinal slot 28 and also with a longitudinal arm 26 with a transverse slot 27, these longitudinal arms 26, 24 being provided with a screw ( By attaching to each other by 25), both longitudinal and lateral adjustments are possible. The longitudinal arm 26 is connected to the yoke-shaped clip member 6a by a hinge portion 23, which clip member 6a can be mounted from above on the metal clip body 6b, and the clip Groove-shaped grooves 6c are provided on the side of the body 6b, while the inner surface of the clip member 6a is formed in a corresponding shape. In this case, therefore, the clip member 6a and the clip body 6b together form the attaching clip 6. By this snap fitting engagement, the binocular small magnifying glass can be easily removed and replaced. The small and inconspicuous clip body 6b can be permanently fixed to the connection 3 of the glasses. The clip body 6b can be fixed to almost any type of glasses using a fixing ring portion 10 made of soft metal to form a ring surrounding the connecting portion 3, and such fixing ring portion 10 Both ends of the s) are holes penetrating through the clip body 6b and are accommodated in holes of the same size as those formed in the clip body 8 shown in FIG. It is determined to be able to engage with the spiral of the ring portion (10). Such clips are small in size, inconspicuous, durable and suitable for almost all types of glasses.

Another feature of the present invention is that the fixing assembly and the miniature magnifying glass are not only light but also block only a small part of the field of view. This feature can be advantageously achieved by designing a thin walled small magnifying glass jacket for the dividing angle of the field of view covered by a small eyepiece. In addition, the flat shape and position of the arms are selected to minimize disturbance of the field of view. At the same time, this arm can be installed to be adjusted to the distance between both eyes by its hinge point, which ensures that the small magnifying glass always has a constant fixed focus. The small magnifying glass can be configured to have a length of about 20 to 30 mm and a diameter of about 10 mm. When the eyepiece is positioned very close to the lens of the spectacles, the distance from the eye to the eyepiece constitutes about 20 mm. Alternative lenses have a diameter determined by the angle of division and the length of the miniature magnifying glass.

According to the present invention, there is provided a fixing assembly for an attachment that can be mounted on a user's glasses, which is inconspicuous, convenient to use and inexpensive as possible, and has various uses for fixing various attachments. do. If the attachment is a binocular miniature magnifier, the fixing assembly and miniature magnifier are configured so that they do not shield the field of vision as much as possible so that the field of view is easily passed through the miniature magnifier and directed directly at the same target being examined and magnified by such a miniature magnifier.
