Description

[Detailed explanation of the idea] [Industrial application field] This invention relates to eyeglass frames.

[Conventional technology and its problems]

Both the left and right lens frames in the eyeglass frame are fitted to the face by placing the temples over the ears.

However, even if the temples are pressed against the temples, both lens frames gradually deform in the direction away from the eyeballs, making it difficult to keep the glasses always fitted to the face.

This invention is an attempt to solve the above-mentioned problems, and its purpose is to create a resilient eyeglass frame in which the temples are always closer to the face.

[Means for solving problems]

In order to solve the above problems, this invention uses a plate spring that connects the bridge that connects both the left and right lens frames so that it can be bent back and forth with respect to both lens frames, and that the center part is fixed to the back side of the bridge. An eyeglass frame whose both ends are pressed from the back side to a protruding corner portion formed at the connecting portion of the lens frame to the bridge and projecting from the back side to the outer circumferential portion, thereby giving both lens frames a restorability of constantly bending toward the back side. This is what I did.

〔Example〕

FIG. 1 is a rear view of an example of a spectacle frame according to the present invention, where 1 is both left and right lens frames, 2 is a bridge connecting both lens frames, and 3 is a temple.

As shown in enlarged views in FIGS. 2 and 4, the bridge 2 is connected to both lens frames 1 by a screw shaft 4 extending in the vertical direction so that it can be bent in the front and rear directions.

Also, a leaf spring 5 is attached to the back side of the bridge,
Its center part is fixed to the center part of the bridge 2 with a rivet 6, and both ends thereof are attached to the corner parts 7 that protrude toward the rear side and the outer circumferential side, which are formed on the lens frame at the position where the bridge 2 is connected to the lens frame 1. It is pressed from the back side, and in this state, as shown by the arrow in Figure 5,
The lens frame 1 has a restorability in that it is bent toward the back side using the screw shaft 4 as a fulcrum.

FIG. 6 shows an arrangement in which both lens frames 1a are provided with an auxiliary mechanism for further increasing the restorability of bending the lens frames 1a toward the back side using a screw shaft 4 (not shown) as a fulcrum. That is, short pipes 8 are fixed to the upper frame portions of both lens frames 1a by welding, facing in opposite directions, and the opposing outer ends of both pipes are closed.

As shown by the chain lines in the same figure, both ends of the sub-bridge 9 made of a linear spring curved into a gentle arc are attached to both the pipes 8, 8, with the direction of curvature in the same direction as the main bridge 2 (front side). The secondary bridge 9 is also provided with the ability to restore both lens frames 1a to the back side and in the facing direction of both lens frames, further increasing the function of the main bridge 2. ing.

〔effect〕

The glasses frame of this invention has the following effects.

The bridge that connects both the left and right lens frames can be bent forward and backward relative to both lens frames, and on the back side of the bridge there is a leaf spring whose center part is fixed to the bridge, and both ends of this leaf spring Since it is pressed from the back side to the protruding corner part formed on the bridge connecting part on the back side and the outer periphery, both lens frames have the resilience to always bend toward the back side, and both lens frames are always kept in the same direction. At the same time, the temples are also moved closer to the sides of the face to maintain a normal fit to the face.

Claims (1)

[Scope of utility model registration request] A bridge that connects both the left and right lens frames is connected to both lens frames so that it can be bent back and forth, and the center portion is fixed to the back side of the bridge.Both ends of the leaf spring are connected to the connecting portion of the lens frame to the bridge. An eyeglass frame characterized in that a protruding corner portion formed on the back side and an outer peripheral portion is pressed from the back side to give both lens frames the restorability of always bending to the back side.
