The present invention relates to a spectacle frame having a main structure and two rims supported by the main structure and each receiving one lens, and more particularly, their rims on at least a portion of the outer periphery of the lens. An eyeglass frame having a relatively rigid upper rim extending over and a relatively flexible lower rim for supporting a lens.

Such spectacle frames are described, in particular, in British Patent 533,161 and French Patent No. 1,094,381 and various additional patents thereof. The advantage of these frames is that they are lighter because they are used as part of a flexible lower rim that can reduce cross-sectional area.

According to the configuration described in British Patent No. 533,161, since the flexible lower rim is permanently connected to the main structure at both ends, it becomes difficult to replace when broken.

In the spectacle frame according to French Patent No. 1,094,381 and its various additional patents, each flexible lower rim is wedge detachably connected to the main structure at both ends by passing through two apertures associated with the main structure. In practice, two through holes are often formed at the corresponding ends of the upper rim, and the main structure is a simple center plate for attaching the upper rim thereof.

However, according to French Patent No. 1,094,381, further patents 73,203, the main structure extends from one of its side pieces to the other over the entire width of the spectacle frame, and the flexible lower rim fixing apertures are formed directly in the main structure and The upper rim, which is merely an ornament with respect to the rim, extends over all or part of the circumference of the rim, is wedged between the lens and the main structure, and other special connections other than simple fixation between the upper rim and the main structure. This is not used. Either way, the use of a flexible lower rim to hold the lens, and the structure of the main structure and the rim supported by the main structure when permanently connected to the main structure, actually requires the selection of a relatively solid material, Otherwise, the lens may easily fall out of the rim unintentionally by a simple deformation of the entire frame.

For this reason, the main frame and the upper rim supported by it have been made of metal in the spectacle frame for using a flexible lower rim that has been commercially available. This structure was satisfactory, but had a solid sense as a whole, and no conformance to the needs of the mode was obtained.

In particular, in the spectacle frame for using the flexible lower rim of the above type, the decorative and manufacturing advantages of the synthetic material with respect to the other type of the spectacle frame cannot be economically realized.

The decorative upper rim described in French Patent No. 1,094,381 to the additional patent No. 73,293 is an attempt to realize a spectacle frame by a combination of a flexible lower rim, ie a combination of a synthetic material and a metal material. The upper rim to be formed can be easily manufactured from the synthetic material.

However, in this structure, the use of synthetic materials is limited, and the main part of the spectacle frame is made of metal. The configuration of the main structure of the spectacle frame having a flexible lower rim as a synthetic material is also limited.

However, according to this configuration, in addition to the expensive structure of connecting the tip of the flexible lower rim to the capsta to ensure the tensile force, the interior of the main structure of the synthetic material is synthesized to obtain the required rigidity. Because of the need for reinforcement with the material, the manufacturing costs are higher and the inherent advantages of the synthetic material are not realized without being simply remanufactured by molding.

Also, in this configuration, no specific upper rim is used, and since the lens is directly engaged in the groove of the main structure by its soft surface, the spectacle frame cannot be used as a single support of two constant lenses, that is, sunglass. .

An object of the present invention is to enable the economical use of synthetic materials in the normal form in the main structure of the spectacle frame with the flexible lower rim of the above type which can be used for any lens.

Thus, according to the present invention, it has a main structure and two rims supported by the main structure so as to receive a single lens, each of which has an upper rim for clamping the lens and two apertures related to the main structure. Eyeglasses consisting of a flexible lower rim adapted to connect to the main structure at each tip by passing therethrough, and four through holes are formed to receive at least one tip of the flexible lower rim, and the other two through holes are formed in the upper rim. They are provided with a spectacle frame, which is spaced from the main structure to the upper rim, the lower rim corresponding to each other so as to connect the upper rim to the main structure.

According to a preferred embodiment of the present invention, each tip of the flexible lower rim has the above configuration.

According to another preferred embodiment of the present invention, it is possible to have only the one end of the flexible lower rim as the above structure, and this configuration also realizes the required connection. In this case, preferably, the upper rim and the other locking plate are disposed at the other end of the flexible lower rim, and the locking plate through which the lower rim passes acts together with the main structure to fix the other end of the lower rim. As a modification, three through holes may be formed in the main structure such that the flexible lower rim passes in an S shape. In all cases, each upper rim is firmly connected to the main structure supporting it, and connecting this upper rim to the main structure is economically done by the lower rim coupled thereto. This lower rim has two functions: connecting the upper rim to the main structure, and surrounding the lens, i.e. as a lens frame for holding the lens when mounted.

Such connection of the upper rim to the main structure by means of the flexible lower rim is done at the manufacturing plant, and the operation of the entire spectacle frame when attaching the lens is simply performed at the sales office.

The upper rim used in the present invention can be made of metal irrespective of the main structure, and after the main structure is manufactured, it can be used to reinforce the outer surface of the main structure. The main structure can be produced from a synthetic material integrally with a wide range of compliance, for example by this molding, according to known techniques. In summary, according to the spectacle frame of the present invention, by manufacturing the main structure from the synthetic material without reinforcement, both flexibility and robustness necessary for holding the spectacle lens can be obtained relatively inexpensively. The upper rim made of metal is attached to the constituent parts of the synthetic material, the spectacle frame is lightened as a whole, and the mounting of the lens is very simple.

In addition, by using the upper rim, the spectacle frame according to the present invention can be advantageously used not only for the lens for correction but also for the lens for sunglass.

The features and advantages of the present invention will become more apparent from the following description of the preferred embodiments shown in the accompanying drawings.

The illustrated frame according to the present invention generally has a main structure 10 and two rims supported by the main structure 10 to accommodate the lenses 11, respectively, and the figure shows one lens 11. A flexible lower rim adapted to be connected to the main structure 10 by passing at both ends through the upper rim 12 cooperating with the lens to be pinched and fixed, and two through holes 14 of the main structure 10. It consists of (13).

In the example shown, the main structure 10 has two arc-shaped curved portions 15 as a whole for each lens 11, and these curved portions 15 have openings as an example as shown. It is connected to each other by a central bridge 16. At the distal end of each curved portion 15, a through hole 14 is formed in the illustrated embodiment by means of the groove 17 for passing and fixing the corresponding flexible lower rim 13. In the transverse side end of the curved part 15 on the temple side, the main structure 10 is integrally provided so that it may protrude rearward in the Example which shows the projection 18 for extracting the side support body 19. As shown in FIG.

If desired, the main structure 10 may be manufactured integrally from synthetic material, for example by molding. In this case, as shown in FIG. 1, the main structure 10 may be integrally provided with the nose contact plate 20 which protrudes rearward, and the nose adhesion plate 20 has the nose side of the curved part 15. As shown in FIG. To form part of.

In the embodiment shown in FIGS. 1-8, each upper rim 12 has a substantially semi-circular shape depending on the contour of the curved portion 15 of the main structure 10.

The upper rim 12 has a flange 22 protruding on the inner circumference over at least a portion of the inner circumference, and at least the tip portion of the cross-sectional shape of the flange 22 has the same shape as the half cross-sectional shape of the flexible lower rim 13. Have In addition, the lens 11 is provided with a groove 21 along its outer circumferential surface, and the groove 21 has a lower lower portion 13 that is flexible to the lower portion thereof and a flange 22 to the upper portion thereof.

As shown in FIGS. 1-5, each upper rim is formed of two members, that is, a metal channel member 23, and a molded body 24 made of a synthetic material inserted into the groove of the channel member 23. You may be. The protruding portion of the molded body 24 forms the flange 22.

In the variant shown in FIG. 6, the flange 22 is cast by metal integrally with the rest of the upper rim 12. In any case, at least one tip of the upper rim 12 is formed with two through holes 26 corresponding to the through holes 14 of the main structure 10, and the flange 22 is stopped at a position adjacent to the tip. It is.

In the embodiment shown in FIG. 1-13, these through holes 26 are formed at each tip of the upper rim 12. As shown in FIG. In addition, a fitting fixing means is formed between each upper rim 12 and the main structure 10. In the illustrated embodiment, the fitting means consist of a flaw 27 formed in the main structure 10 at least partially engaging the upper rim 12 in each upper rim 12.

The upper rim 12 and the groove 27 of the main structure 10 have a compensating cross-sectional shape, for example a rectangular cross-sectional shape. In addition, in the embodiment shown in each figure, the depth of the groove 27 of the main structure 10 is at least equal to the height of the upper rim 12 when viewed in cross section, so that each upper rim 12 is in the transverse direction. It is covered by the main structure as a whole. Further, in the embodiment of FIGS. 1-8 in which each upper rim 12 has a limited extension range, the extension range of the curved portion 15 of the main structure 10 is at least an extension range of the upper rim 12. Since the same as, each upper rim 12 is covered by the main structure 10 also in the longitudinal direction. Therefore, once each upper rim 12 is mounted at a predetermined position on the main structure 10, it is not visible from the outside at all except for the case where the main structure 10 is transparent.

Mounting the upper rim 12 on the main structure 10 in such a predetermined position is done by simply inserting the upper rim 12 into the groove 27 of the curved portion 15 of the main structure 10, The through hole 26 of the upper rim 12 coincides with the through hole 14 of the curved portion 15 in this case. In practice, this mounting is done at the factory.

According to the present invention, four through holes are formed to accommodate at least one tip (both ends in the embodiment of Fig. 1-13 in FIG. 1-1) of the flexible lower rim 13, and two of them are formed in the main structure 10 The two through holes 26 are formed in the upper rim 12, and these through holes 14 and 26 correspond to each other from the main structure 10 to the upper rim 12 two by one.

In the embodiment shown in FIGS. 1-13, each flexible lower rim 13 has a first through hole 26 of the upper rim 12 followed by a first through hole 14 of the main structure 10. After passing through, the second through hole 14 of the main structure 10 finally passes through the second through hole 26 of the upper rim 12 in the reverse direction and finally overlaps.

Such engagement of the flexible lower rim 13 into the apertures 14, 26 is done according to conventional forms and will not be described in detail here. It is only here that this engagement is carried out at the factory prior to mounting the lens 11, and each flexible lower rim 13 is sufficient to have a length suitable for the particular shape of the lens 11 at the point of sale at its installation. As a modification, this engagement may be performed by the seller at the time of attachment of the lens 11. In any case, according to the present invention, each of the flexible lower rims 13 has a main structure (not shown) in at least one end of the upper rim 12 (in both ends in the embodiment of Fig. 1-13). 10).

In the embodiment shown in FIG. 7, each upper rim 12 has a cutout groove 22 'on its inner circumferential surface instead of a protruding flange 22. In the embodiment shown in FIG. In this case, the outer circumferential portion of the lens 11 should have a protruding surface to fit in the upper rim 12 at the top and a groove 21 for accommodating the flexible lower rim 13 at the bottom.

According to a variant embodiment shown in FIG. 8, the nasal contact plate 20 is supported at least by the upper rim 12 in the main structure 10. In this case, the nose contact plate 20 is squeezed to the tip of the arm 28 which is mounted by a corresponding upper rim 12, for example by welding.

Similarly, in this variant embodiment, each upper rim 12 is provided with projections 18, for example by welding, and the main structure 10 is provided with grooves for fixing through the projections 18 ( 27 has a side notch (not shown) in communication with the protrusion 18.

In the embodiment thus far, each upper rim 12 has a limited extension.

In the embodiment of FIGS. 9-11, the upper rim 12 extends almost circularly and surrounds the lens 11 over the entire circumference.

As in the embodiment thus far, the upper rim 12 can only be fitted and fixed in the grooves 27 of the main structure 10. The upper rim 12 is adapted to cooperate with the flexible lower rim 13 in a fixed shape on the outer circumference. (See also 9 and 10).

In the embodiment shown in Figs. 9 and 10, notch grooves 22 'are formed in the inner circumference of each upper rim 12. Figs. However, as a modification, the flanges 22 protruding from the upper rims 12 may be formed in the same manner as in the previous embodiment, and the flanges 22 may be formed as separate bodies 24 (the twelfth). Fig. 13) or integrally (Fig. 13).

In any case, each of the upper rims 12 according to the present embodiment has two deformed portions 30 which are almost half-waveform at almost opposite positions, and each deformed portion 30 includes Two through holes 26 are formed for passing the corresponding ends of the flexible lower rim 13, and a third through hole 31 is provided at the connection point between the deformable portion 30 and the normal portion of the upper rim 12. Formed.

In this case, the wide part 33 (FIG. 11) for accommodating each deformation | transformation part 30 is formed in the corresponding location of the groove | channel 27 of the main structure 10. As shown in FIG.

Mounting the flexible lower rim 13 in a predetermined position is performed according to the above-described process. However, the front end of the flexible lower rim 13 is connected to the through holes 14 and 26 of the main structure 10 and the upper rim 12 before the openings of those through holes 14 and 26 and the corresponding upper rim 12. The third through hole 31 is engaged from the outside.

In the alternative embodiment shown in FIGS. 14-23, the corresponding through holes between the main structure 10 and each of the upper rims 12 are formed only for one end of the corresponding flexible lower rim 13.

Even with this configuration, it has been empirically found that a rigid assembly can be obtained by connecting the upper rim 12 and the main structure 10 as required. As an example, as shown, each flexible lower rim 13 has two nose holes 14 of the main structure 10 and two holes 26 of the corresponding upper rim 12 at the nose side. Passed.

In the embodiment shown in Figs. 14-22, the stop plate 35 is provided on the other side of the flexible lower rim 13, and the flexible lower rim 13 is passed through the stop plate 35.

The gage plate 35 cooperates with the main structure 10 to fix the other end of the flexible lower rim 13, apart from the lower rim 13. In practice, the locking plate 35 is provided with two through holes 37 for passing the flexible lower rim 13. The retaining plates 14 and 15 are, for example, in the notches 17 in the grooves 27 of the main structure 10 on the inner surface of the main structure 10, that is, on the lens 11 side, in FIGS. It is located. Therefore, the locking plate 35 is on the extension line of the upper rim 12, and the extension range of the upper rim 12 is limited for this reason.

In the illustrated embodiment, the locking plate 35 has a curved shape, the recessed surface side of which is directed to the lens 11 and the bottom surface thereof is supported on the bottom surface of the groove 27 of the main structure 10. . The through hole 37 of the locking plate 35 substantially coincides with the through hole 14 of the main structure 10. Therefore, assuming that the portion of the locking plate 35 away from the upper rim 12 is not formed, the configuration is the same as that of the previous embodiment. However, the difference is that the locking plate 35 is movable relative to each main structure 10. Therefore, since the through hole 37 of the locking plate 35 can be aligned with the through hole 14 of the main structure 10 without having to change the position of the upper rim 12, the assembling becomes very simple.

As in the above-described embodiment, the flexible lower rim 13 passes through the first through hole 37 of the stop plate 35, passes through two through holes 14 of the main structure 10 in turn, and then the stop plate. Passes through the second through hole 37 in (35).

In the modified embodiment shown in Figs. 16-28, for example, the locking plate 35 formed as shown as a flat plate is a locking plate on the outer side of the main structure 10, i.e., opposite to the lens 11; It is arrange | positioned at the slot 38 of the main structure 10 narrower than (35). The stop plate 35 is disposed in the groove 17 of the main structure 10 in this embodiment, and the slot 38 is formed in the bottom face 39 of the groove 17, which is more than the stop plate 35. Because of its length, the locking plate 35 is movable relative to the main structure 10 in parallel with the slot 38 as in the case of the embodiment described above.

The upper rim 12 has two through holes 26 for passing the corresponding ends of the flexible lower rim 13 opposite the slots 38, and the lower rim 13 has a It passes through the slot 38 of the main structure 10 between the through hole 37 and the through hole 26 of the upper rim 12.

Therefore, the configuration of this embodiment is the same as the above-described embodiment, provided that the locking plate 35 does not form a separate portion from the main structure 10, and the earthwork 37 of the locking plate 35 has a main structure. Replaced by the through-holes in (10). It is the same as in the above-described embodiment that assembly is easy because the stop plate 35 is movable.

In addition, since the locking plate 35 is located outside the main structure 10, a special aesthetic appearance is given to the main structure 10.

In the embodiment shown in FIGS. 19-22, the main structure 10 is made of a plastic material which is a preferred material, and the stop plate 35 is at least partially disposed inside the thickness of the main structure.

As an example, in the case of 19 and 20 degrees in which the main structure 10 is manufactured by molding, the locking plate 35 is integrally embedded in the inside of the main structure 10 at the time of molding. The locking plate 35 is disposed in the corresponding cutout groove 17 of the main structure 10 so that the through hole 37 corresponds to the through hole 14 of the main structure 10 as in the above-described embodiment. The locking plate 35 has side notches 40 so as to be securely locked to the raw material portion of the main structure 10.

In the variant shown in FIGS. 21 and 22, the locking plate 35 is on the surface of the main structure 10 and the bottom plate of the insert 43 which integrally supports the corresponding knuckle 18. 42). The through hole 37 is formed at right angles to the groove (not shown) of the main structure 10 which opens to the inner surface for the flexible lower rim 13 to pass through.

In the embodiment shown in FIG. 23, the main structure 10 has three through holes 14 substantially parallel to each other for receiving corresponding ends of the flexible lower rim 13, the flexible lower rim 13 being It passes through the through hole 14 to form a nearly S-shaped double loop, and especially when the main structure 10 is made of plastic, so that the lower rim 13 is securely held as compared to the case of a single loop. It is.

As shown, two of these apertures 14 open to the common groove 17 on the outer side, ie opposite the lens 11, and the flexible lower rim 13 has these two apertures 14. The third through hole 14 is directly opened to the outer surface of the main structure 10 so as to cut off the tip of the lower rim 13 so as to be flush with the outer surface of the main structure 10. To be able.

The present invention is not limited to the above-described embodiments and includes various possible modifications. In particular, the two upper rims may be connected by one or more bridges as required, and in this case, the main structure may be composed of two parts each constituted by one retainer.

In addition, each upper rim 12 or each component thereof may be made of an extruded part which is cut as necessary and bent into a desired shape, and for this reason, the upper rim 12 according to the embodiment of FIGS. The groove 21 is formed not only in the lower portion of the upper rim 12 that cooperates with the lower rim 13, but also formed in the upper portion which does not actually play any role.

As a variant, each upper rim 12 may cooperate with a flange formed in the main structure 10 for fitting at the top thereof, in which case the groove 27 is not necessary. In any case, each upper rim 12 or at least the channel member 23 thereof is preferably made of metal. However, a plastic material selected to have the required strength may be used.

It is preferable that the main structure 10 is made of a synthetic material as described above with respect to the embodiments shown in Figs. 21-23, and this synthetic material is preferably selected to exhibit some flexibility. However, as a modification, the main holder 10 may be made of a light metal or a light alloy.
