Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a spectacle frame having a structure in which a lens is held by a flexible wire (eg, a nylon thread) fitted into a groove formed on an edge surface of the lens.
[0002]
[Prior art]
Conventionally, as this kind of eyeglass frame, one having a structure as shown in FIG. 6 is known. The spectacle frame 1 includes a pair of left and right nose rims 3, 3 that hold the nose side edge surfaces of the left and right lenses 2, 2, a bridge 4 that connects the two nose rims 3, 3 to each other, A flexible wire (eg, nylon thread) 6 that fits into the groove 5 formed on the edge surface and holds the edge surface of the lens 2 is provided. At both ends of the nose side rim 2, two locking holes 7, 8 for locking the ends of the wire 6 are provided in parallel in the longitudinal direction. These locking holes 7, 8 penetrate from the inner surface contacting the edge surface of the lens 2 to the outer surface, and bend after inserting the end 6 a of the wire 6 from the inside to the outside of the locking hole 7. The free end 6b is inserted from the outside to the inside of the locking hole 8 and is housed in the groove 5 of the lens 2 to be locked and fixed. A ridge 9 that fits into the groove 5 of the lens 2 is integrally formed on an inner surface of the nose rim 3 except for both ends where the locking holes 7 and 8 are provided.
[0003]
[Problems to be solved by the invention]
The conventional lens holding structure of the spectacle frame 1 is not preferable in design because the end 6a of the wire 6 bends and protrudes outside the nose rim 3. In addition, when a component such as a blow is attached adjacent to the upper surface of the nose side rim 3, the locking holes 7, 8 are hidden by the component, and the end 6a of the wire 6 is inserted through the locking holes 7, 8. There is a problem that it cannot be locked.
[0004]
An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide an eyeglass frame excellent in design, in which an operation of locking and fixing an end of a wire can be easily performed from the inside of a nose rim. I do.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pair of left and right nose rims that are connected to each other by a bridge and hold the nose side edge surfaces of the left and right lenses, and are fitted into grooves formed in the edge surfaces of the lenses. A flexible wire that holds the lens edge surface, wherein the two ends of the wire are locked and fixed to both ends of the nose rim to hold the lens. Two notches that open inward are provided at the end on the temple side, and the ends of the wire are inserted into the notches from the inside of the nose rim through the openings and locked and fixed. Is configured.
[0006]
Further, a gap larger than the diameter of the wire is provided between a component attached adjacent to the upper side of the nose side rim and an upper surface of a portion provided with the cutout portion of the nose side rim, and When the end of the wire rod locked and fixed to the notch portion is covered and hidden by a part, the end of the wire rod can be easily locked and fixed to the notch portion from the lateral direction, and the design is improved. An excellent spectacle frame can be obtained.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an eyeglass frame 10 according to the present invention, and the same components as those of the conventional eyeglass frame 1 shown in FIG.
[0008]
At the temple-side end 3a of the nose-side rim 3, two notches 11, 12 are provided in the longitudinal direction instead of the conventional locking holes 7, 8, as shown in FIGS. They are provided at appropriate intervals. Both notches 11 and 12 have openings 13 and 14 on the inner side of the nose side rim 3 (the inner side facing the face when wearing glasses).
[0009]
A blow 15 extending along the upper surface of the nose side rim 3 is fixed to the upper surface of the nose side rim 3 by brazing or the like. As shown in FIGS. 2 and 3, the blow 15 has a notch 16 at a position facing the temple-side end 3 a of the nasal rim 3 provided with the notches 11 and 12. Due to the notch 16, a gap C larger than the diameter of the wire 6 is formed between the wire 6 and the nose 15, and the end 6 a of the wire 6 is cut out from the inside of the nose 3 through the openings 13 and 14. The work of locking and fixing by inserting through 11 and 12 can be easily performed. In addition, the end 6a of the wire 6 locked and fixed to the cutouts 11 and 12 is covered with the blow 15 and does not protrude, so that the design is excellent and the commercial value can be enhanced.
[0010]
【The invention's effect】
As described above, the eyeglass frame of the present invention has a simple structure in which two notches that open inward are provided at the temple-side end of the nose-side rim. It can be inserted from the inside of the rim and locked and fixed, and there is no hindrance to the locking and fixing work by parts such as blows attached to the upper surface of the nose side rim.
[0011]
In addition, since the locking end of the wire can be covered and hidden by the component, the design is excellent and the commercial value can be increased.
