[Prior art]

 As is well known, there are a plastic frame, a metal frame, a combination frame made of a combination of plastic and metal, and the like as the front frame of the spectacles. Of these front frames, front frames that use plastic as the material often use embedded hinges to hinge the front frames to the temples.

As such an embedded hinge, an embedded type butterfly piece 4 as shown in FIG. 5 is generally used, and an arrow-shaped anchor portion 41 and a substantially rectangular parallelepiped plate are provided with pivot holes. The anchor portion 41 and the piece portion 42 are linearly and integrally formed. The anchor portion 41 is embedded in the outer end portion 11 of the front frame 1, while the piece portion 42 is hinged to the piece portion 31 protruding from the base end portion of the temple 3 by means of a pivot P. It is connected.

However, in the embedded hinge using the linear butterfly piece 4 as described above, the temple 3 is opened at a right angle to the front frame 1 in a direction in which the temple 3 further expands outward (outward expansion). When a pressing force (in the opening direction) is applied, a force in the direction of pulling out the embedded anchor part 41 directly acts on the anchor part 41 via the pivotal pivot P, and acts like nail pulling. Damages the embedded part. In this way, the pressing force in the outward expansion direction is directly transmitted to the anchor part 41, so if the pulling force directly due to this pressing force is repeatedly applied, the wobble of the anchor part 41 will gradually increase, and There was a risk that the butterfly 4 would slip out from the root of the anchor 41 and the worst situation would occur.

[Embodiment of device]

 Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings. 1 is a perspective view of the eyeglasses of the first embodiment of the present invention, FIG. 2 is an enlarged exploded perspective view showing the vicinity of the bracket in the first embodiment, and FIG. 3 is a view of an embedded portion in the first embodiment. FIG. 4 is an enlarged plan view showing the vicinity of the bracket together with the cross section, FIG. 4 is a side view of the eyeglasses of the first embodiment, and FIG. 5 shows the vicinity of the butterfly piece together with the cross section of the embedded portion in the conventional embodiment. FIG. 6 is an enlarged plan view, FIG. 6 is an enlarged disassembled perspective view showing the vicinity of the bracket in the second embodiment, and FIG. 7 is an enlarged disassembled perspective view showing the vicinity of the bracket in the third embodiment.

First, the first embodiment glasses of the present invention will be described with reference to FIGS. 1 to 5. In the figure, what is designated by reference numeral 1 is a front frame for holding a pair of left and right lenses L, which is made of a thermoplastic (acetate, celluloid resin, etc.). The outer end 11 located on the ear side of the front frame 1 is thicker and wider than other frame parts, and has a size sufficient to embed one end of a bracket tip 2 described later. . A lateral groove 12 is formed on the outer surface of the outer end portion 11. In the front frame 1 of the present embodiment, the entire frame is made of thermoplastic, but a blow bar made of thermoplastic may be attached to the upper edge of the lens L.

Reference numeral 2 indicates a bracket that is brought out from both ends of the front frame 1 to the rear, and is made of a highly elastic metal (nickel alloy, nickel silver, etc.). The bracket 2 is a substantially self-shaped connecting member as shown in FIG. 2, and connects the front frame 1 and the temple 3. The bracket tip 2 has a plate-shaped abutting portion 23 that abuts against the outer end portion 11 of the front frame 1, and an arrowhead-shaped anchor portion 21 is protrudingly provided on the back surface of the abutting portion 23. The anchor portion 21 is hardened by heating the front frame 1 made of a thermoplastic to press the tip of the anchor portion 21 into the outer end portion 11 in a state where the front frame 1 is heated and softened and left to cool appropriately. , Is stably embedded in the outer end portion 11. A linear elastic take-out portion 24 is convexly formed in a U shape on the outer edge of the hitting portion 23, and the side edge portion 24a of the elastic take-out portion 24 on the hitting portion 23 side is formed. By fitting in the lateral groove 12 of the outer end portion 11, it is possible to prevent the linear elastic carry-out portion 24 from swinging vertically on the outer surface of the outer end portion 11. Further, the temple-side end of the elastic carry-out portion 24 is formed with carry-out ends 22 and 22 of two pieces, and the carry-out ends 22 and 22 are provided with vertically piercing pivot holes. There is. A pivot P is inserted through the pivot hole and a pivot hole formed in the piece 31 at the base end of the temple 3, and the bracket tip 2 and the temple 3 are hinged.

The greatest feature of the present invention is that the bracket tip 2 having such a curved convex shape is used instead of the conventional linear butterfly piece 4 as shown in FIG. In other words, in the conventional embedding structure using the butterfly piece 4, the anchor embedded in the outer end portion 11 of the front frame 1 when an excessive pressing force is applied in the outward expansion direction of the temple 3. The force of pulling out the portion 41 directly acts on the anchor portion 41. On the other hand, in the embedded structure using the bracket tip 2 of the present invention, the contact portion 23 is in contact with the outer end portion 11 of the front frame 1 and the U-shaped elastic carry-out portion 24 is contacted. Since the side edge portion 24a on the side of the portion 23 is pressed against the outer surface of the front frame 1, even if an unreasonable pressing force in the outward spreading direction is applied, the pressing force is dispersed and relaxed, Moreover, the cushioning effect of the highly elastic material further reduces the stress. Therefore, the pulling force acting on the anchor portion 21 of the bracket tip 2 can be greatly reduced, and as a result, the embedded state of the anchor portion 21 of the bracket tip 2 can be stably maintained for a long period of time. The durability of eyeglasses can be greatly improved.

Further, as shown in FIG. 4, the spectacles manufactured by using the bracket tip 2 of the present invention have a smart appearance near the outer end portion 11 of the front frame 1 and use the conventional embedded hinge. It is different from the solid appearance of plastic eyeglasses. As described above, by adopting the curved bracket-shaped bracket 2 as in the present invention, instead of the conventional eyeglass parts corresponding to the embedded hinge, not only the effect of reducing the pulling force of the anchor portion 21 but also the variation is obtained. It is also possible to obtain glasses with a rich appearance.

Next, a bracket structure according to a second embodiment of the present invention will be described with reference to FIG. The second embodiment differs from the bracket tip 2 of the first embodiment in that a bracket tip 2 having a band-shaped elastic carry-out portion 24 is adopted. Since the side edge portion 24a of the strip-shaped elastic carrying-out portion 24 on the contact portion 23 side is pressed flatly on the outer surface of the outer end portion 11 of the front frame 1, the bracket edge of the first embodiment. The contact area is significantly larger than that of the line contact of No. 2, and as a result, the effect of dispersing the pressing force in the outward expansion direction by the contact surface is large.

Finally, a bracket structure according to a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, the separation type bracket tip 2 including the hook-shaped anchor piece 2a and the rail portion 2b that should clamp the anchor piece 2a on the outer end portion 11 of the front frame 1 is adopted. It differs from the bracket tip 2 of the first and second embodiments. The hook-shaped anchor piece 2a is formed by protruding an anchor portion 21 on a substantially rectangular plate, and the rail portion 2b is formed by bending one wire in parallel. In the vicinity of the folded-back portion at the substantially center of this wire, there is a contact portion 23 that abuts the outer end portion 11 of the front frame 1, and the outer edge of this contact portion 23 has two elastic carry-out portions 24, 24. It has a U-shaped convex curve. When the hook-shaped anchor piece 2a and the rail portion 2b thus formed are fixed to the outer end portion 11 of the front frame 1, the rail portion 2b is attached to the outer end portion 11 of the front frame 1 which is heat-softened. When the contact portion 23 is abutted and the tip of the anchor portion 21 of the anchor piece 2a is press-fitted into the outer end portion 11 from the opposite side of the contact portion 23, the front frame 1 in a heat-heated and flexible state is cooled and cured, The anchor portion 21 is embedded in the outer end portion 11 with the contact portion 23 being sandwiched between the outer end portion 11 and the anchor piece 2a. In this case, the side edges 24a, 24a of the elastic carry-out portions 24, 24 on the contact portion 23 side are pressed against each other at two locations on the outer surface of the front frame 1, so that the temple 3 is expanded outside. It becomes possible to more effectively reduce the pulling force of the anchor portion 21 that is sometimes applied, as compared with the bracket tip 2 of the first embodiment.

The embodiment of the present invention is generally as described above, but the present invention is not limited to the above-described embodiment, and various modifications are made within the scope of the “claim for utility model registration”. For example, in the bracket tip 2 of the present embodiment, the U-shaped elastic take-out portion 24 is formed into a linear shape, a band-like shape, or a rail-like curved shape, but this elastic take-out portion is not necessary. It is needless to say that the portion 24 can be formed in other shapes, and such changes are also within the technical scope of the present invention.
