Claims

[Scope of utility model registration request]

The inner sides of the pair of left and right lens frames 1, 1 into which the multifocal lenses are respectively fitted are connected by a central connecting piece 2, and the inner sides of both lens frames 1, 1 are connected to each other by a central connecting piece 2 at a position extending downward from the central connecting piece 2. , a main body in which grooves 6, 6 are formed from the inside, respectively, so that the two face each other almost in a V-shape, left and right nose pieces 13, 13, and a V-shape on the front sides of the nose pieces 13, 13. Left and right leg pieces 11,1 arranged in
1 is connected to a nosepiece member 14 which is integrally connected at the upper position, and the left and right leg pieces 11
, 11 move up and down in the grooves 6, 6 of the main body, and are made of an elastic material, and their V-shaped shape is slightly wider at the lower part than the V-shaped shape of the grooves 6, 6. When the leg pieces 11, 11 are fitted into the grooves 6, 6, a slight elasticity is generated in the leg pieces 11, 11 outward. This multifocal eyeglass frame is provided with locking means for locking the leg pieces 11, 11 at two upper and lower positions between the 11, 11 side and the groove 6, 6 side.
