[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eyeglass frame to which a front frame is attached.

[0002]

[Prior art]

 Conventionally, eyeglasses in which a front frame is further attached to the front frame of the eyeglasses are often used. As is well known, there are many cases where people with nearsightedness need sunglasses, or those who have presbyopia but also have nearsightedness.In such cases, the sunglasses apron frame is attached to the glasses for nearsightedness. For example, glasses for presbyopia may be used with a myopia lens in the apron frame.

By the way, there are some problems in the spectacle frame provided with the conventional apron frame. One of them is that the mounting structure is complicated and the cost is high, and the fitting state is unfavorable, which causes rattling, and the apron frame is not stable. Further, the spectacle frame to which the apron frame is attached requires a wading which is laid over the upper end of the rim for fixing the lens, and the aforesaid frame is attached to the wading.

In addition to the functionality of the spectacle frame, the weight of the design is large, and the wading for attaching the apron frame may be an obstacle in the design. You will be constrained. On the other hand, in the case of conventional glasses with a front frame attached, the front frame part becomes heavy, and if you wear it for a long time, you feel tired, and the nose pad that supports the front side presses the nose. I have a pain on both sides. Furthermore, by attaching the apron frame, the front portion becomes thicker in addition to the above weight increase, which is not desirable in terms of design.

【Example】

 FIG. 1 shows an embodiment of the apron frame and the spectacle frame of the present invention. In the figure, reference numeral 1 indicates a front hanging frame, 2 indicates a front frame, and this front hanging frame 1 is fixed to a front frame 2 of a steering wheel and is detachable. The above-mentioned mega is a resin frame, the front frame 2 is formed with rims 4 and 4 for holding the lenses 3 and 3 symmetrically, and tools 5, 5 are provided on both sides of the front frame 2. Is connected so that it can be folded.

Then, on both sides of the front frame 2 and at the connecting portions of the temples 5 and 5, there are embedded stoppers 6 and 6, and the stoppers 6 and 6 are fitted to the front frame. It has a structure in which the stoppers 7, 7 provided in 1 are fitted. The stopper receiver 6 forms a concave portion, and one stopper 7 has a convex portion, and the convex portion fits into the concave portion so that the apron frame 1 is attached to the front frame 2.

By the way, the aforesaid frame 1 is also the same resin frame as the front frame 2, but a thin lens resin plate of about 1 mm is used. Of course, the resin plate for the lens is not limited, but by using the resin plate for the lens, it is not necessary to insert the lens into the apron frame 1 again, and the lens and the frame are integrally formed. You can do it. Therefore, the lens resin plate is cut with an end mill or the like so that its outer shape is almost the same as that of the front frame 2, and a groove 21 having a sphere shape for making it look like the lens is fitted is formed. To process. Further, a flat resin plate is bent into the same shape as the front frame 2 by hot pressing, and the stoppers 7 are fixed to both sides.

FIG. 2 is a plan view in which the front frame 1 is attached to the front frame 2. FIG. 2 is an actual size, but the thickness of the front frame 1 is larger than that of the front frame 2 made of resin glasses. Is so thin and therefore light in weight that there is no sense of attaching the apron frame 1. As described above, the apron frame 1 is structured such that it can be detachably attached by fitting the stopper 7 of the apron frame 1 to the stopper receiver 6 provided on the front frame 2. FIG. 3 shows one specific example.

FIG. 3 a is a front view of the stopper bracket 6, and b is a sectional view of the stopper bracket 6 fitted with the stopper bracket 7. The stopper bracket 6 is attached to the front frame 2. It is embedded. The stopper 6 is integrated with one of the hinge pieces 9a of the hinge 8 connecting the vines 5, and the butterfly piece 9a protruding to the back side of the front frame 2 and the other one embedded in the vine 5 side. The butterfly piece 9b is flexibly connected via a screw. The stopper 6 projects outwardly from the brim 10a, 10b and is embedded so as not to come off from the front frame 2 and to prevent rattling. A recess 11 is formed in the center, and the entrance side of the recess 11 is formed. A spring 12 is fastened to this.

The spring is fitted into a groove formed on the inlet side of the recess 11 and fixed thereto, and has sandwiching portions 13 a and 13 b which are parallel to each other. The distance between the holding portions 13a and 13b can be expanded by the deformation of the spring. On the other hand, a stopper 7 is fixed to the front hanging frame 1, and the stopper 7 has a convex portion 14 protruding to the back side. The stopper 7 is composed of a plate 15 located on the front surface and a back plate 16 located on the back surface, and pins 17 extending from both sides of the plate 15 are inserted into the holes formed in the apron frame 1 to form a back plate. It is crimped in a state of being fitted into 16 holes. The convex portion 14 is formed on the back plate 16.

FIG. 3b shows a case where this convex portion 14 is fitted into the concave portion 11 of the stopper receiver 6 and is fixed by both the sandwiching portions 13a and 13b of the spring 12, but the tip portion of the convex portion 14 is Since it has a large diameter, the convex portion 14 that once pushes the holding portions 13a and 13b and fits into the concave portion 11 does not come off by itself, and the front frame 1 is stably attached. By the way, although the spectacle frame described in the above embodiment is made of resin for both the front frame 2 and the front frame 1, the present invention is not limited to the resin frame.

FIG. 4 shows an embodiment in the case of metal eyeglass frames. The basic structure is the same as that of the above-mentioned embodiment, but the stopper receiver 18 is brazed to the back side of the end piece 19, and the protrusion 14 of the end piece 7 of the front frame 1 is inserted into the end piece 19. The holes 20 are formed. On the other hand, when the front hanging frame 1 is made of metal, the front hanging frame 1 may have the same shape as the front frame 2, and the stoppers 7 may be brazed to the end portions on both sides.

Further, the form of the stopper 6 and the stopper 7 is arbitrary, and the present invention may be any one as long as the front hanging frame 1 is detachably attached by a button type. Therefore, the spring 12 is not always necessary. As described above, the apron-type spectacle frame of the present invention is one in which a stopper is provided on the apron frame, the front frame of the spectacles has a stopper, and the stopper is fitted to the stopper. , The following effects can be obtained.

[0016]

[Effect of device]

 The apron-type glasses of the present invention are easy to put on and take off because the apron frame is fixed to the front frame of the eyeglasses with a button type, and the stopper receivers are provided on both sides of the front frame. The apron frame that is attached due to the provision of a stopper is stable without rattling. If a resin plate for lenses is used as the apron frame, the thickness will be extremely thin and lightweight, and it will not look like eyeglasses with the apron frame attached. The pain in the area is reduced. Furthermore, since the front hanging frame is fixed on both sides with a button type and is stable, there is no possibility of being scratched by contact with the front frame.
