Abstract

PURPOSE:To reduce the number of manufacturing stages and the manufacturing cost by bending a grooved wire so as to form lens frames together with a bridge. CONSTITUTION:A grooved wire is circularly bent so as to form a bridge 1 at the center and circular lens frames 2, 2 at the right and left sides of the bridge 1, and the ends of the bent wire are fixed on the bridge 1 with screws 3, 3. The ends of a grooved wire are bent at about 90 deg., the wire is bent so that the ends of the bent parts 4, 4 are joined together at the center of a bridge 1 while forming lens frames 2', 2' of suitable shape at the right and left sides of the bridge 1, and the ends of the bent parts 4, 4 are joined together and fixed on the bridge 1 with screws 3, 3.

Description

DETAILED DESCRIPTION OF THE INVENTION A conventional eyeglass frame is formed by separately manufacturing left and right lens frames by brazing a seal to each end of the groove line, and then brazing the lens frame to the bridge. Therefore, a step is required to braze a joint to each end of the groove line of the lens frame and to braze each lens frame to the bridge. Also, since the temples are connected to joints or connection pieces brazed to the joints, the temple mounting position is limited by the joints.

The present invention eliminates the brazing process, reduces the manufacturing process, reduces manufacturing costs, and eliminates changes in material properties due to heat received during brazing, and allows the temple to be attached to any position. It was made in a similar manner.

Next, the present invention will be explained with reference to the illustrated embodiments.

In a spectacle frame using a circular lens as shown in Fig. 1, a bridge (1) is formed in the center with one groove line, and circular lens frames (2) (2) are formed on the left and right sides. and attach each end of this circularly bent miso wire to the bridge (1) with screws (
It is fixed and formed with 8 pins (3).

The one shown in Figure 2 has each end of the groove birch bent at about 90 degrees.
The ends of this bent fA (4) (4) meet at the center of the bridge (1), and a suitably shaped lens frame (2') (
2'), the bent portions (4) and (4) are brought together at their respective ends and fixed to the bridge (1) with screws (8) and (3).

The one shown in Fig. 3 is a belt-shaped plate that is bent to form a rectangular tube shape, and a groove (7) is provided at the tip of the lower side (5) so that the lower end of the vertical side (6) fits in. Bend the frame (8) along the groove lines to form a lens frame (2) on the left and right, similar to the one in Fig.
4) so that their tips meet at the center of the bridge (1),
This bridge CI) and the bent part (4) at the tip of the groove line (
4) with a tightening frame (8), and the lower side of this tightening frame (5)
The lower end of the inner vertical side (6) is fitted into the groove (7) at the tip of the bridge (1) and the bent portions (4) (4) are tightened and fixed.

Note that (9) is a hinge connecting piece, and the mounting of this bridge and the tip of the groove line is not limited to the screws or clamping frame shown in 1.2.8, but may be mounted by any other suitable means. do.

According to the present invention, there is no full-heat brazing process for forming eyeglass frames, so there is no material change due to heat during brazing, and the frame has uniform hardness throughout and has no weak points against bending. Furthermore, since both the lens frame and the bridge can be formed by bending a single line, the number of manufacturing steps is reduced and the manufacturing cost is accordingly reduced. Furthermore, since there is no joint in the lens frame, there are many advantages such as the ability to attach the temples to areas where they will not be overlooked.
