Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frame for eyeglasses, and particularly to a frame in which lenses can be easily attached and detached.

Eyeglass frames have diversified in recent years, and on the one hand, there are those that emphasize functionality such as weight reduction through the development of new materials, and on the other hand, there are a large number of frames that are designed to follow the trends that change year by year and sweeten design elements. types are in circulation.

However, no matter which one of these many eyeglass frames (hereinafter referred to as "frame") is taken up, lenses cannot be attached to the frame. There is no change in the method of fixing,
It is uniform regardless of the type of frame. In other words, one method is to incorporate the lens into the annular frame that makes up the front frame.In this method, after the lens is incorporated, the frame is fixed with screws.There is also a method called the Nyroll method. However, this does not use a circular frame, but uses a cutout frame,
The cutout part is used to secure the lens to the frame using nylon thread. Generally, the former fixed method is the majority. In any of these systems, it is impossible for the glasses user to change the lenses by himself or to change the frames to sunglasses. However, in reality, it would be very convenient for people who wear glasses all the time to be able to freely change their glasses according to changes in the seasons or depending on the purpose, and tastes regarding glasses also change significantly.

Incidentally, there have been developed and commercially available eyeglasses with interchangeable lenses that meet the above requirements. It attaches to the lenses of conventional glasses. This is a partial frame with the upper half of the frame to be fixed (Fig. 1).However, if the upper half of the frame is simply cut out, lenses can be exchanged freely, but it is difficult to hang the glasses. When removing, etc.
If an extra external force is applied to the frame, the lens will come off.

Frames that have become extremely lightweight in recent years have low rigidity against torsion and bending, and the cutout frame is similar to a curved beam in the field of material mechanics, and it is easy to resist small external forces acting on the tip of the frame. It transforms into

By the way, the present invention aims to eliminate the above-mentioned drawbacks and provide a frame with interchangeable lenses. Using a holding notch frame, two of the notch frames are fixed symmetrically to a connecting rod, and a guard is attached to the connecting rod to provide a temple.

In other words, the frame is constructed so that deformation of the frame due to all external forces is absorbed by the deformation of the connecting rod, and no distortion is applied to the notch frame that holds the lens.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

The most typical form of the frame according to the present invention is as shown in FIG. 2, and the frame is composed of a front frame 1 and a crane 2, and the front frame 1 is a cutout frame with a cutout at the bottom. 3,
It consists of a connecting rod 4 and a nose pad 6, and the nose pad 6 is attached to the notch frame 3 and brazed to the connecting rod 4 symmetrically. On the other hand, front frame 1
The connection with the crane 2 is not done by directly brazing the endpiece 5 to the frame as in the past, but by brazing the endpiece 5 using both ends of the connecting rod 4, and connecting the crane 2 through the hinge 7. It is connected to 2.

Therefore, the upper part of the cutout frame 3 is connected to the connecting rod 4.
Although they are connected by brazing,
Deformation of the connecting rod 4 does not destroy the shape of the cutout frame 3. That is, when the connecting rod 4 is twisted or bent due to the action of an unreasonable external force such as when the temple 2 is opened or closed, the central portion 9 is deformed due to the bending deformation, and the notch frame 3 that holds the lens 8 becomes a kind of deformation. It works as an independent rigid body, and the notch frame 3 itself is not distorted. By the way, Fig. 2 shows only one form of the frame according to the present invention, and the form of the frame is influenced by fashion and has no choice but to change its design.On the other hand, with the advent of new materials, its functional beauty also changes. However, the frame according to the present invention is not dependent on the design of the cutout frame 3, the connecting rod 4, or the crane 2, etc. Therefore, the connecting rod 4 is not limited to a straight one as shown in FIG. 2, but also includes cases in which the central portion 9 is curved or the cross-sectional area is changed.

In other words, the eyeglass frame of the present invention is constructed by attaching end pieces 5 to both ends of a connecting rod 4 to provide temples 2, and two cutout frames 3 symmetrically attached to each other by brazing or the like around a central portion 9. Since the frame that holds the lens 8 is cut out, it is possible to easily convert the lens 8 by yourself.

For example, even with one frame, you can use colored lenses 8 or change to sunglasses in the summer when the sun's rays are strong or on sunny days, or as you get older, you can change lenses 8 to lenses 8 with a power that suits your eyes. Iku etc.
Its uses will be greatly expanded, and the taste for glasses will also be greatly expanded.

Furthermore, it becomes possible to freely consider the shape of the lens 8 and use the portion that does not fit into the notch frame 3. Moreover, even though the frame uses the notch frame 3 for replacing the lens 8, it has a special structure with the connecting rod 4, and all the effects of external force are absorbed by the deformation of the connecting rod 4. Even if the temple 2 is twisted, bent, or expanded to an extreme extent, the lens 8 will not come off the notch frame 3, and the frame as a whole is incomparably larger than conventional frames in terms of elasticity. It is.

In addition, the frame as a whole has excellent elasticity,
In addition, the lens 8 can be replaced freely using the notch frame 3, so that when a large force (impact force) is applied to the lens, which would cause damage to the lens 8 in a conventional frame, the deformation of the frame can cause damage to the lens 8. This is an extremely excellent frame for eyeglasses, as it has the great effect of preventing damage to the lens 8 and protecting the user's eyes by removing the lens 8 from time to time.
