Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eyeglass frame having a plastic portion at the temple.

Conventionally, as a structure in which a plastic part is provided in the temple part, a structure has been used in which a plastic plate is attached to a metal rod, or a structure in which the entire periphery of a metal core extending from the hinge part is made of plastic. . The former structure uses plate materials, while the latter structure requires the metal core to be located in the center and cover the entire circumference, making it difficult to make the temple parts thinner and lighter. Furthermore, in the latter structure, since injection molding is used, the plastic material is limited, the variety of colors is small, and it is impossible to form patterns, so there is little freedom in design. In addition, multiple plastic annular bodies are fitted around the outer periphery of the metal rod,
There is also a known structure that allows them to slide on each other to create flexibility (Japanese Patent Publication No. 54-30302).
However, in this structure, the plastic annular body only serves a decorative function and does not function as a strength member, resulting in an increase in the overall size.

The present invention was devised for the purpose of improving these points and obtaining a structure of the temple part that is thin and light, and which can realize a variety of designs.

That is, in the present invention, a plastic annular body is fitted onto the outer periphery of only the front part of a metal rod body, and is bonded to form a strength member that mainly bears bending elasticity, and the front end of this plastic annular body is made of metal. This is an eyeglass frame that has a temple part that is brought into contact with the hinge part and a metal annular body is brought into contact with the rear end.

An example of this eyeglass frame will be explained with reference to the drawings. The temple part 12 of the eyeglass frame 10 is provided with a metal hinge part 16 at the front end of a metal rod that connects with the lens part, an ear hook part 18 at the rear end, and a plastic ring around the front outer periphery of the rod. The body 20 and the metal annular body 22 are fitted and bonded together. This plastic annular body 20 consists of two parts 20a and 20b with a decorative metal annular body 22' sandwiched between them.The front end abuts the hinge part 16, and the rear end abuts the metal annular body 22. are in contact with each other.

Since this eyeglass frame 10 has the above-described configuration, the rod body 14 and the annular bodies 20, 22, 22' can be made thin and lightweight. In particular, the plastic annular body 20 is fitted and adhered to the outer periphery of the front portion of the rod 14, which is subjected to a large bending stress, so that it acts as a strength member that bears the bending elasticity and contributes greatly to weight reduction. Furthermore, this plastic annular body 20
Since the front and rear ends are protected by the metal hinge portion 16 and the annular body 22, damage such as cracking is less likely to occur despite bearing stress. Further, the plastic annular body 20 has a simple shape as a whole and is easy to mold, so that colors and patterns can be freely applied. Furthermore, this plastic ring body 2
0 consists of two parts 20a and 20b in this example, sandwiching one decorative metal annular body 22', but it can also be formed from one or more parts.
It goes without saying that the decorative metal ring may be omitted or two or more may be used. If the metal bar 14 and the metal annular bodies 22, 22' are plated before assembly, they will not rust even if sweat gets in between them and the plastic annular body while wearing glasses. Therefore, it is convenient.

As mentioned above, the eyeglass frame of the present invention has a plastic annular body fitted into a metal rod, so that
It is easy to construct a thin and lightweight structure, and it is also possible to freely select colors and patterns to realize a wide range of designs. Moreover, the plastic annular body is integrated with the metal rod by adhesive and is located at the front of the rod, where bending stress is large, so it functions primarily as a strength member that bears bending elasticity. It is also possible to reduce the weight. In addition, the plastic annular body has a structure in which the front and rear ends are protected by metal, so that even if stress is applied, it is unlikely to cause damage such as cracking, and can withstand long-term use.
