[0027]
Next, a specific procedure for manufacturing the rim-lock glasses of this embodiment will be described below based on FIGS.
[0028]
First, as shown in FIG. 7, an annular rim 1 is produced. In this embodiment, the rim 1 is manufactured by punching a thin metal plate (for example, a titanium alloy). At this time, since it is cut together with the lock piece base material 2 in a later step, it is preferable to make the cut piece in consideration. The rim 1 can be formed by bending a long metal plate.
[0029]
Next, on the outer peripheral edge of the rim 1, a lock piece base material 2 (size is, for example, 2.5 mm in length, 1.3 mm in width, and about 3.0 mm in thickness) is fixed (brazed in this embodiment). (See FIG. 8). At this time, two through-holes 22 (diameter 0.8 mm) are formed in the lock piece base material 2 with a required interval (0.4 mm).
[0030]
And as shown in FIG. 9, in rim 1 and the lock piece base material 2, it cuts between XY. In the present embodiment, the interval of XY is slightly wider (0.5 mm) between the two through holes 22 and 22, and the opposing side surfaces of the through holes 22 and 22 are cut out by 0.05 mm. At this time, an odd-shaped long hole is formed by leaving the outer periphery of the through-holes 22 and 22 at a position where the side surfaces of the holes are left open.
[0031]
Thus, as shown in FIG. 10, the lock pieces 2A and 2B are formed at the side edges of the lock end portions 11A and 11B of the divided rim 1, while the wide ends are formed at the opposite side edges of the lock pieces 2A and 2B. The cutout portions 21A and 21B are formed in a cove shape. Thereafter, a concave groove 12 into which the lens L can be fitted is cut and formed on the inner peripheral surface of the rim 1 and bent according to the peripheral shape of the lens L to hold the rim 1.
[0032]
After that, as shown in FIG. 11, with the lens L filled on the inner edge of the rim 1, the lock end portions 11A and 11B and the lock pieces 2A and 2B are joined to connect the notches 21A and 21B. The rim 1 can also be connected by forming the deformed long hole 21 and fitting the joint member 3 having the same cross-sectional shape as the hole.
[0033]
The joint member 3 is made of an acrylic resin material, the thickness of the joint member 3 is about 5.0 mm, and the end of the joint member 3 fitted into the deformed long hole 21 is extra from the inside of the hole (each 1 .0mm) In a state where it protrudes and is fitted into the deformed long hole 21, a flange 31 is formed by thermocompression bonding the both ends, and this flange 31 locks and stops the edge of the deformed long hole 21. You can wear it (see Figure 12).
[0034]
The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of “Claims”. The shape of the through-hole 22 provided in the lock piece 2 is not limited to a circular shape, and any shape can be used as long as the shape can be changed as long as the joint member 3 can be locked by forming a deformed cross section. good. Alternatively, four through holes 22 may be formed in the lock piece 2 so that two deformed elongated holes 21 may be produced.
[0035]
In addition to the titanium alloy, the material used for the rim 1 can also be a metal used as a conventional spectacle component material, such as a nickel alloy, white or white, and the joint member 3 is not limited to an acrylic resin material. It may be made of other thermoplastic resin such as polyethylene resin, polystyrene resin, polycarbonate resin, or metal material, and any of them belongs to the technical scope of the present invention.
[0036]
【The invention's effect】
As described above with reference to the embodiment, the rim lock glasses obtained by applying the present invention form a deformed elongated hole by joining the notch portion of the medium wide to the butt, and a joint member is formed in the deformed elongated hole. Since the rim can be connected by a simple operation of simply inserting the lens, it is not necessary to perform a troublesome screwing operation for fixing the lens.
[0037]
Further, in the method invention, the lock piece can be formed at the end of the rim simply by cutting the rim and the lock piece base material fixed to the outer peripheral edge at the same time, so the operation is very simple. As a result, productivity can be greatly improved, and it can greatly contribute to rationalization of eyeglass frame manufacturing.
