Problems solved by technology

[0004] However, in the above-mentioned spectacle frame, since the frame locking part and the pile head are firmly fixed together by the frame locking part screw, the lens is fixed in the frame, so it is possible to prevent the lens from falling out due to external impact. The lens falls off inside the frame, but the lens is subjected to strong pressure from the outer edge to the inner side, especially in the case of using a plastic lens, the lens will be deformed near the outer edge and warp
When the lens is warped and deformed, the power of the lens before it is fixed in the frame will change, so the follo

Embodiment Construction

[0042] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. figure 1 It is a perspective view partially showing the appearance of the spectacle frame in the first embodiment of the present invention.

[0043] The spectacle frame 1 is a left-right symmetrical metal frame made of metal materials, and mainly includes: a pair of frames 3, 3 into which the lens 2 is placed; a nose bridge 4 connecting the pair of frames 3, 3; used to fix the lens 2 on the The variable picture frame locking device 5 in the picture frame 3; the overlapping pile head 6 connected on the variable picture frame locking device 5; linked on the covering pile head 6, and hanging under the state of wearing the spectacle frame 1 The mirror legs 7 on the user's ears; the mirror legs 7 are rotatably mounted on the hinge 8 on the pile head 6; The foot member 11 connected to the nose pad 9 connected to the user's nose. Although in figure 1 In the fi...

Abstract

This invention provides a variable rim lock of a spectacle frame that makes it easy to attach and detach a lens in and from a rim and can fix the lens in the rim while preventing the lens from being strained, and the spectacle frame equipped with the variable rim lock. The variable rim lock of the spectacle frame fixes the lens in the rim (Fig. (a)) by urging a 2nd rim lock member 5b toward a ceiling wall 20 of a 1st rim lock member 5a with the urging force of an elastic member 30, so strain deformation of the lens due to pressure applied inward from the outer edge of the lens is reducible. The lens in the rim can be attached and detached (Fig. (b)) by moving the 2nd rim lock member 5b while pushing and contracting the elastic member 30 toward the umbrella part 42 of a screw member 40, so the lens can easily be attached and detached without the need to clamp nor unclmap the screw member 40.

Description

technical field [0001] The present invention relates to a variable frame locking device for spectacle frames and a spectacle frame equipped with the variable spectacle frame locking device, in particular to a lens that can be easily attached and detached from the spectacle frame and that can prevent the lens from warping. A variable spectacle frame locking device for a spectacle frame in a spectacle frame and a spectacle frame equipped with the variable spectacle frame locking device. Background technique [0002] As disclosed in Japanese Unexamined Patent Publication No. 62-95513, a spectacle frame is known in which lenses are fixed in the frame. This spectacle frame is integrally formed with: a nose bridge connecting a pair of spectacle frames, a nose pad connected to the nose bridge of the spectacle frame and abutting against the user's nose, piles connected to the outside of both sides of the spectacle frame, and The mirror legs abutted against the user's head are mount...
