Description
【発明の詳細な説明】 本発明は、メタルフレーム眼鏡の改良に係り。[Detailed description of the invention] The present invention relates to improvements in metal frame eyeglasses.
その目的とするところは1部品数が極端に少なく、シか
もロウ付は作業を要せずして能率的に作製できる新式メ
タルフレーム眼鏡を提供するにある。The purpose is to provide a new type of metal frame eyeglasses that can be manufactured efficiently with an extremely small number of parts and no additional work required for soldering.
また1本発明の他の目的は、金属組織的に最も頑丈で、
しかも一体感があってデザイン的にもスッキリしたメタ
ルフレーム眼鏡を提供するにある。Another object of the present invention is to provide the strongest metallographic structure,
Moreover, we provide metal frame glasses that have a sense of unity and a clean design.
周知のとおり、従来のメタルフレーム眼鏡のフロント枠

タルフレーム眼鏡はロウ付は部分が不用意に外れたり。As is well known, the front frame portion of conventional metal frame eyeglasses is manufactured by separately manufacturing the bridge, rim, and hinge bracket, and then brazing these parts together in a predetermined arrangement. For this reason, parts of conventional metal frame glasses with solder may come off carelessly.
ロウ付は部分に見苦しいパリや隙間が出来たりすること
もあり3品質管理面において大変な不利益があったこと
に加え、ロウ付は作業によって組立工程が繁雑にならざ
るを得す頗る非能率的であった。Brazing may create unsightly cracks or gaps in parts, which is a major disadvantage in terms of quality control.In addition, brazing is extremely inefficient as the assembly process becomes complicated due to the work involved. It was a target.
本発明は、従来メタルフレーム眼鏡に上記の如き不便が
あったことに鑑みてなされたものであって、これを第1

レーム眼鏡を実現するものである。The present invention was made in view of the above-mentioned inconveniences in conventional metal frame glasses.
To explain based on the embodiment shown in FIG. 3 and FIG. 3, there is a bridge 1, upper rims 2, 2 with a lens-compatible shape extending from both ends of the bridge 1, and temples 3 at the ends of these upper rims 2, 2. Hinge brackets 4 and 4 that pivot 3
The present invention provides metal frame eyeglasses characterized by forming a metallurgically integrated structure.

とより、チタン合金。Further notes regarding the present invention are as follows: 2. Bridge of glasses according to the present invention 1. Upper rim 2. The metal material used to form the hinge bracket 1-4 includes not only the conventionally known nickel alloy material but also a titanium alloy material.
ベリリウム合金、ステンレス、アルミ合金なども採用さ
れる。Beryllium alloy, stainless steel, aluminum alloy, etc. are also used.

ればよいのである(第1図参照)。1. Bridge using such metal material. Press molding is the most suitable method for metallurgically molding the upper rim 2° and the hinge bracket 4, but when this press molding method is adopted, cavities are formed in both the upper mold and the lower mold. It is preferable to use a molding die that is suitable for molding, and by doing so, it is possible to create a beautiful shape that fits around the entire circumference of the molded product. In the thus obtained molded product, a pivot hole 41 is formed in the temple pivot portion of the hinge bracket 4 by drilling or other means, and a descending rim 5 is attached to the lower end surface of the upper rim 2 with a screw S. All you have to do is drill a screw hole for fastening (see Figure 1).

枢着されるべきテンプル3も、ヒンジ片31部分を冶金
的に一体成形しであるのが好ましい。しかして、その成
形にもプレス成形法を採用するものとする。It is also preferable that the temple 3, which is to be pivotally attached to the pivot hole 41 of the hinge bracket 4 by the shaft S, has the hinge piece 31 portion formed integrally with metallurgy. Therefore, the press molding method is also adopted for the molding.

きにフレーム軽量化という要請に沿い得るのであり、か
\る利点も特記せらるべきである。However, in this way, Bridge 1. The metal frame eyeglasses of the present invention, in which the upper rim 2° and the hinge bracket 4 are metallographically integrated, have a front design with smooth and natural lines, so they have a strikingly sleek appearance.
In addition, unlike conventional products, brazed products do not have the weak point of breaking at a certain point, have surprisingly high shear strength, and exhibit ideal springiness.In addition, brazed products do not require any work, so the manufacturing process can be simplified. The simplification greatly increases productivity, the number of parts is drastically reduced, which makes inventory management easier, and the frequency of defective products decreases, which is advantageous in terms of quality control. In addition, the present invention can meet the demand for reducing the weight of the frame when titanium alloy or aluminum alloy material is used as the material metal, and this advantage should also be noted.
以下2本発明を実施例をもって、さらに詳細に説明する

It is cut into 5 lengths, annealed in a vacuum furnace, and temporarily bent so that it can be inserted into the cavity shape of a press mold. Next, the temporarily bent metal wire is inserted into the cavity of a press mold (both the upper mold and the lower mold have cavities) and pressed, and then unnecessary parts are cut using a cutting die. leave
