【Example】

 FIG. 1 shows an apron frame constituting the apron frame type eyeglass frame of the present invention. Both rims 1 and 1 are connected by a connecting member 2, and a rim lock 3 is provided on the outer side of the rim so that the sunglasses lens 4 can be attached to and detached from the rim 1. A locking spring 5 is attached so as to cover the rim lock 3, and the locking spring 5 is curved into an appropriate shape to form a locking portion 6. This front hanging frame is attached by locking the locking springs 5, 5 attached to both sides to the front frame of the glasses. A fitting groove 7 is formed in the connecting member 2.

FIG. 2 shows an eyeglass frame to which the aforesaid frame is attached. The basic shape of this spectacle frame is the same as the conventional one, and both rims 8 and 8 are connected by a connecting member 9. The rim 8 has a cutout 10 on the outside, and brazes the end pieces 11a and 11b on both sides of the end piece 10 so that the end piece 12 is formed by the end pieces 11a and 11b. The crane 13 is connected to the.

As is clear from the figure, the cut end 10 does not have a rim lock, but the end piece 12 has a function as a rim lock. That is, the connecting portions 14a and 14b of the two end pieces 11a and 11b are parallel to each other and extend toward the temple, and a screw pin 15 is provided between the connecting portions 14a and 14b to fasten the connecting portions 14a and 14b. That is, by tightening the screw pin 15, the end pieces 11a and 11b come closer to each other, and the width of the cut end 10 of the rim 8 becomes smaller, so that the lens fitted to the rim 8 can be prevented from coming off.

A joint shaft 16 is provided at the tip of the connecting portion 14 so that the temple 13 can be folded. As a matter of course, as the connecting means of the temple 13, it is free to use a hinge joint which has been frequently used conventionally. On the other hand, a convex piece 17 is formed on the upper surface of the connecting member 9 that connects the two rims 8, 8 and a nose pad 18 is attached to the inside of the rim 8.

FIG. 3 shows a case where a front hanging frame is attached to the front part of the spectacle frame. The locking spring 5, which is appropriately curved, is located between the end pieces 11a and 11b and is attached by the locking portion 6 being locked to the screw pin 15. The locking spring 5 applies a spring force to the screw pin 15, and the front frame is stably attached by the spring force without rattling. In this case, the connecting member 2 of the apron frame is placed on the upper surface of the connecting member 9 of the spectacle frame, and the convex piece 17 is fitted into the fitting groove 7 for positioning.

If the front spring frame is superposed on the front portion of the eyeglasses and the insertion spring 5 is inserted between both the end pieces 11a and 11b and pushed in, the leaf spring 5 is deformed and the engagement portion 6 is released. It will be locked to the screw pin 15. Then, the connecting member 2 is placed on the connecting member 9 of the front part and the convex piece 17 is fitted into the fitting groove 7. On the contrary, when the front frame is removed, if the connecting member 2 is removed from the convex piece 17 and pulled, the locking spring 5 is deformed and comes off from the screw pin 15.

Here, the locking spring 5 is formed by appropriately bending and deforming a leaf spring, but the locking structure with the screw pin 15 is arbitrary and is not limited to the case shown in FIG. In the example, the rim lock 12 is provided with the rim lock function without using the rim lock, but the roy lock may be a conventional roy lock. However, the rail has a locking groove with which the locking portion 6 of the locking spring 5 can be locked.

Further, the positions of the locking springs for mounting the front hanging frame are not limited to both sides, but may be provided inside. Therefore, the position of the locking member that the locking spring locks is not in the end position but in another suitable place. FIG. 4 shows an embodiment in this case, in which locking springs 19 and 19 are provided inside the rims 1 and 1 of the front frame, and one of the megaframes has locking members 20 inside the rims 8 and 8. 20 is brazed. Accordingly, the locking springs 19 and 19 are locked to the locking members 20 and 20, so that the front frame is attached. As described above, the apron-type eyeglass frame of the present invention is equipped with locking springs on both sides of the apron frame, which are then locked to the front end of the glasses and the locking members provided at other appropriate places. This is possible, and the following effects can be obtained.
