In the spectacle frame according to the present invention, the modern bend held on the back side of the ear is formed at a substantially boundary between the part A and the part B on the uneven portion of the back side of the ear. Along with the end length, a portion corresponding to the portion a of the modern bent portion is formed into a shape that fits into the portion a and abuts against the portion a, and at the tip of the modern bent portion, the portion b It is characterized in that a modern end member made of a soft material to be abutted is combined.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

The bent portion 11 of the modern 1 fixed to the back of the ear (a portion from the vicinity of the half point O of the modern to the modern end) is the first half of the indentation in the uneven portion of the back of the ear. The length ends approximately at the boundary between the part a on the side and the part B on the second half. A portion of the bent portion 11 of the modern 1 corresponding to the portion a is formed so as to fit into the portion a and abut the portion a.

A portion of the uneven portion of the back side of the ear that comes into contact with the portion b, that is, a portion corresponding to the modern end portion is made of a flexible material. The portion made of this flexible material is the modern end member 1a, and the modern end member 1a is connected to and integrated with the tip of the bent portion 11 of the modern 1. In other words, the modern end member 1a is a portion corresponding to the range I in FIG.

The modern end member 1a is made of a soft material, for example, a soft plastic. Preferably, the material of the modern end member 1a is a kind of silicone resin. Modern end members made of silicone resin
A sufficiently good familiar contact with the part B in the irregularities on the back side of the ear is obtained, and it is hard to slip. The flexibility of the modern end member 1a can be varied in a wide range in correlation with the spring strength of the temple T. In general, for example, when the spring strength of the temple is the strongest, in the field of the eyeglass industry, The flexibility of a stainless steel wire with a spring force of about 0.8 mm, which is applied to a member referred to by those skilled in the art as "passing over" (a kind of decorative member attached over the left and right lens edges above the bridge). In this case, the spring strength of the temple is the softest, and the stainless steel wire described above may have a spring force of about 0.5 mm in diameter.

The flexible modern end member 1a is connected to the tip of the modern bent portion 11 and is integrated. This connection is performed by, for example, insert molding in which the modern bent member 11 other than the modern end member 1a is inserted into a molding die and the modern end member 1a is formed by injection molding using the molding die. Specifications. In the case of this specification, the connection between the modern end member 1a and the modern bent portion 11 can be formed as shown in FIGS. In FIG. 4, the modern end member 1a and the modern bent portion 11 are shown in a straight state before being formed as shown in FIG.

In the case of a connection having such specifications, a perforation 1c may be formed in the connection portion of the modern bent portion 11. The perforation 1c is composed of the modern end member 1a and the modern bend 11
To improve the bonding strength of the connecting portion.

In the drawing, reference numeral 12 indicates a core in the modern bent portion 11.

According to the present invention, (a) the modern bent portion has a length that ends substantially at the boundary between the portions (a) and (b) in the uneven portion of the back side of the ear, and the modern bent portion corresponds to the portion (a). Is formed so as to be fitted into the portion a and abutted against the portion a. (B) The portion of the uneven portion abutting against the portion b, that is, the modern end member is made of a flexible material, It is connected to the tip of the bend. This has the following effect.

Regarding the configuration (a), the modern bend is
It is shorter than the typical typical modern bend by almost the equivalent of a part. Therefore, it is easy to form a modern bent portion at a portion corresponding to the portion A in the uneven portion of the back side of the ear so as to fit into the portion A and abut the portion A. In this case, the flexibility of the modern end member connected to the distal end of the modern bent portion according to the present invention also contributes to facilitating the formation of the required shape of the portion corresponding to the portion a.

With respect to the configuration (b), the modern end member is lightly pressed against the part B under its flexibility, and is adapted to the shape of the part B so as to make the pressure contact. It corresponds to the shape of the different part B, and its familiarity makes it possible to obtain a good fitting of the modern bend even if the part corresponding to the part A is slightly inconsistent with the shape of the part A. If the attachment of the modern 1 to the temple T can be moved back and forth, the front and rear positions of the modern 1 can be adjusted by adjusting the front and rear positions of the modern 1 even if the position of the part corresponding to the part a of the modern bend is slightly inconsistent with the part a. A good fit and abutment of the portion corresponding to the portion (a) can be obtained, and a good alignment of the modern end member 1a with the portion (b) can also be obtained. Attaching the modern 1 to the temple T so as to be able to move back and forth may be performed by means known per se. In addition, the configuration (b) is designed so that when the glasses are worn and removed,
Eliminates excessive force on the modern end, and makes it easy to wear and remove glasses.

As described above, according to the present invention, the modern bend can be properly fitted to the back of the ear. And, unlike the above-described invention, the portion corresponding to the rear part of the ear of the modern bend has a spring that only contacts the required part of the rear part of the ear and presses this against the required part. It does not require installation, so it is difficult to manufacture, and when wearing or removing glasses, the temple bends without the problem that the hair is easily caught in the modern bend, the design is restricted, and there is no discomfort in appearance. Good fitting of the part and prevention of sliding of the glasses can be obtained.
