[Industrial applications]

 The present invention relates to an eyeglass frame which is devised to prevent the eyeglass from sliding down during wearing.

[0002] In fitting of spectacles, the frame hits the correct position of the head and is fixed or retained (sometimes referred to by those skilled in the art. This fixation or retention is hereinafter referred to as retention). Moreover, it is said that the blood vessels and nerve lines should not be pressed, and that the hit or retention should be obtained such that the blood vessels and nerve lines wrap all over rather than partially hitting.

Regarding the retention of the temple bending portion required for that purpose, the following matters are important, which will be described next with reference to FIG. 5 (plan view).

The shape of the back of the ear, which plays an important role in wearing spectacles, is rough as shown in FIG. 5 by many people. In order to fit the temple curved portion to this unevenness, the temple curved portion is to be entirely in surface contact with the portion of the temple facing the temporal region. It is said that it is effective to firmly press the concave and convex portions in the first half side area (a), and it is enough to make contact with the second half side area (b). Even if it is pressed down strongly in area b, the effect of temple retention is poor for the concave part consisting of areas a and b, and it does not contribute to the prevention of eyeglass slide.

This fitting around the ear is a very important point. The success or failure of the fitting can be judged without a magnet feeling. Here, the sense of magnet is the feeling that the temple bend fits snugly in the back of the ear such that when a spectacle frame is put on the face from the front, the magnetic material is attracted to the magnet. It is well known to those skilled in the art to adjust the shape of the unevenness so that the temple curved portion corresponding to the area (a) is entirely contacted with the area (a) by the surface contact. It is extremely difficult as it is almost impossible.

[0006]

[Prior art]

 Heretofore, it has not been achieved yet to simply and accurately fit the temple bent portion in the concave portion of the concavo-convex portion of the back of the ear.

By the way, conventionally, the fitting of the temple bending portion of the spectacle frame is adjusted by adjusting the tilt angle of the portion, the flap (bending the modern end from the inner side to the outer side so as to match the unevenness of the back of the ear and the head), etc. In addition to doing this, the specifications are such that the quality of the adjustment is judged by the feeling of wearing glasses, but the fit due to the initial adjustment is rarely successful even when wearing for a long time. In fact, spectacle wearers often complain of poor fit within a short time after adjustment, and in many cases, poor fit results in the glasses slipping down during wear.

Further, conventionally, in order to prevent the spectacle frame from slipping down, the bending of the modern is strengthened, or the modern is formed into a shape or structure that is hooked on the rear part of the auricle, or has a configuration substantially similar to this. A measure was taken to attach the hold to the temple. According to these, the spectacles wearer does not provide the feeling of wrapping around the eyewear, and the spectacles are too fixed to the face, and the modern and hold, the nose pads are pinna, blood vessels of the nose, and nerve lines. There was a problem that it caused inconvenience even for general duration of wear due to the pressure on the body and the resulting pain and discomfort. Further, since the eyeglasses can be worn and taken off, there is a problem in that the ease is considerably inferior to that of a general eyeglass frame that does not have such a shape because of the modern shape, structure or hold.

[0009]

[Problems to be solved by the device]

 An object of the present invention is to develop an eyeglass frame that can achieve fitting of a temple bending portion to the back of the ear temporally easily and accurately.

[0010]

Means for Solving the Problems A feature of an eyeglass frame of the present invention is that a temple bend portion retained on the back of the ear is slightly shorter than a standard length of a general temple bend portion, and Concave / concave shape of the temporal region In addition to being shaped so as to conform to the shape of the temporal region, the temple end is contacted only with a flexible line or leaf spring to the lateral region of the concave / convex portion of the temporal region in the latter half of the concave region It is located at a point and attached.

[0011]

【Example】

 The present invention will now be described with reference to the drawings showing the embodiments of the present invention.

The curved portion 11 of the temple 1 retained in the back of the ear behind the head (the portion from the modern half-hanging O point to the modern end) is slightly shorter than the standard length of the curved portion of a general-purpose temple. In other words, it is shaped so that it ends almost at the boundary between the recessed areas I and B in the concavo-convex portion of the back of the ear and substantially conforms to the concavo-convex shape of the temporal portion. The temple 1 may be a plastic temple as long as it is a metal temple, that is, the main part is made of metal and the part contacting the back of the ear and the head is modern.

A chisel 3 is attached to the temple end of the temple bending portion 11 by a wire or a leaf spring 2. The spring 2 is filled with a flexible spring force, and the chisel 3 is located in the second half region B of the concave portion of the concave-convex portion of the ear back temporal region, at a position where it contacts the temporal region. The above-mentioned attachment is performed.

The spectacle frame may be a super slim and lightweight type as shown in FIGS. 1 and 3, or a standard type as shown in FIG.

The position of the concavo-convex portion on the back of the ear that should hold the temple curved portion 11 is not necessarily limited because it varies from person to person, but generally, the inclination angle θ of the temple curved portion 11 is 120 °. It is good to rank. The inclination angle of this degree is the latter half region B of the concave portion of the concave convex portion of the ear back temporal region, and in order to position the chisel 3 at a position where it contacts the temporal region, a general temple bending portion is used. This positioning can be achieved by adapting to a larger number of people with a certain length of temple bend, which is slightly shorter than the standard length.

In general, the distance between the chimney 3 and the tip of the temple end of the temple bending portion 11 is preferably about 2 to 3 mm.

The indicated flexibility of the spring force of the wire or leaf spring 2 can be varied over a wide range in correlation with the spring stiffness of the temple 1, and generally, for example, the temple's spring stiffness is the most rigid. In some cases, the diameter of the stainless steel wire of 0.8 mm is used for a member (a kind of decorative member that is attached to the left and right lens edges above the bridge) that is referred to by those skilled in the art as "crossover" in the technical field of the eyeglass industry. The flexibility of the spring force may be about a certain degree, and if the spring stiffness of the temple is the softest, the flexibility of the spring force of the stainless steel wire shown above may be about 0.54 mm.

In the temple whose spring stiffness is between the stiffness and the softness, the flexibility of the spring force of the spring 2 is based on the flexibility of “the most rigid” or “the softest” as a standard. It may be determined by design.

Although the uneven shape of the back of the ear to hold the temple curved portion is different due to individual differences, in the present invention, the temple curved portion is roughly shaped into the temporal uneven portion. It is in a general form that follows.

Therefore, in order to obtain a good fitting of the temple curved portion with respect to the temporal region of the back of the ear by such a configuration, it is necessary to compensate for the lack of conformity of the shape of the temple curved portion with respect to the concavo-convex shape of the temporal portion. I have to.

In the present invention, the temple bent portion is set to the above-mentioned predetermined length, only the temple end of the temple bent portion is positioned at a predetermined position, and the temple bent portion is attached by the flexible wire or the leaf spring 2.

This structure compensates for the lack of the above-mentioned consistency. That is, the predetermined length of the temple bend makes it possible to hold the front half region a of the concave portion in the temporal concavo-convex portion substantially firmly, and only the flexible spring force of the wire or leaf spring allows the latter half region of the concave portion to be held. While pressing lightly on the b, the press fits nicely into the recess of the area b, thereby compensating for the lack of retention due to the curved part of the temple, and a good feeling that it sticks snugly to the ear (magnetic feeling). It is possible to obtain a good fitting.

Thus, the present invention makes it possible to perform the required fittings for the temple bend portion simply and accurately by using the temple bend portion that is shaped approximately along the shape of the back of the ear.

In the present invention, when a modern or plastic temple is formed by injection molding, only the shim may be simultaneously molded together with the necessary members.
