Description

  The present invention relates to a front frame in which a front portion of spectacles is configured by combining an upper frame and a lower frame formed by bending a single wire.

  There are various forms of glasses frames. However, its basic form is composed of a front part into which a lens fits and two cranes. Both rims are provided on the front frame constituting the front part, lenses are fitted to the rim, and the vines are attached to both sides of the front part via a joint such as a hinge.

FIG. 8 is a specific example showing the most common eyeglass frame. The front frame constituting the front part (a) has both rims (b) and (b) connected by connecting members (c), and the outer side of the rim (b) and (b) ) Are connected.
That is, the rims (B) and (B) are brazed to both ends of the connecting member (C), and the armatures (D) and (D) are brazed to the rims (B) and (B).

  Thus, the front frame which comprises the front part of metal spectacles frames is assembled by brazing each component (part). By the way, when brazing, each part must be correctly positioned, and if the brazing is inadequate, there arises a problem that the parts are peeled off. Furthermore, brazing may not be possible depending on the metal.

On the other hand, a technique for constructing a front frame without brazing has been known in the past. For example, “front frame of spectacles” according to Japanese Patent Application Laid-Open No. 2010-102039 is a front frame of spectacles that does not require brazing and can use aluminum as a material.
That is, in a front frame of spectacles having two rims that surround and fix a lens, and a bridge provided between the two rims, an upper bridge that divides the bridge vertically and continues to the upper frame of the rim; A lower bridge continuous with the lower frame of the rim is provided, and the upper bridge and the lower bridge are fixed via screwing means.

This front frame is integrally formed and has a structure in which a central connecting portion (bridge) is divided. When a lens is fitted to a rim, a screw screwed into the central bridge is loosened. The production cost of the frame is high. Moreover, a slim front frame cannot be constructed, and the design is not good.

And it attaches to the front-end | tip of an armor part so that a vine can be folded via a coupling. Here, the joint structure is not particularly limited, and a simple shaft screw or a general hinge may be used.

  The front frame of the glasses according to the present invention has a structure in which an upper frame and a lower frame are combined, and is connected by engaging notches formed in the upper connecting portion and the lower connecting portion with each other, and provided at both ends. The fastening piece is screwed to the end piece. Therefore, since the front frame is not formed by brazing, the assembly process is simplified and the cost is reduced. That is, the upper frame and the lower frame can be manufactured by accurately molding them using a mold.

  When assembling by brazing, each piece must be correctly positioned. However, in the present invention, the upper frame including both the upper rim portion, the upper connecting portion, and the armored portion, and both the lower rim portion and the lower connecting portion. Since the lower frame provided with the fastening piece is press-molded, the shape and dimensions of these parts are accurate, the notches formed in the upper and lower connecting parts are engaged with each other, and the fastening piece is screwed onto the armature part. A predetermined front frame is completed by stopping. And a lens can be fitted to the rim composed of the upper rim portion and the lower rim portion by loosening the screw of the fastening piece fixed to the armor portion.
