(考案の目的)
本案は眼鏡のブリツジに折曲部を設け眼鏡を折
畳んだとき該折曲部をテンプル側へ「へ」字状に
折曲げて眼鏡折畳時の厚さを縮小させようとする
ものである。[Detailed explanation of the invention] (Purpose of the invention) This invention provides a bending part on the bridge of the glasses, and when the glasses are folded, the bending part is bent toward the temple side in a "H" shape. The aim is to reduce the thickness of the
近年玉形が大きく、フロントも大きくカーブす
る眼鏡枠が愛用されているが、この種の眼鏡枠は
構造上これを折畳んだとき特に眼鏡枠の中央部が
上方へ大きく張出してかさ張る。これを無理に普
通サイズの眼鏡ケースに収納すると枠を変形させ

ても厚さが増すのでポケツト等に入れたとき不体
裁を招く等の欠点があつた。 In recent years, eyeglass frames with large lenses and a greatly curved front have become popular, but due to the structure of this type of eyeglass frame, when folded, the center part of the eyeglass frame in particular protrudes significantly upwards, making it bulky. Forcibly storing them in a regular-sized eyeglass case may cause the frames to deform, and even if they are stored in a special large case, the thickness will increase, resulting in an unsightly appearance when placed in a pocket, etc. It was hot.
本案はフロント中間のブリツジに特定の折曲部
を設けることにより、折畳時のスペースを縮減さ
せるとともに、着用時には自動的に正規の形状に
復元させることを目的として考案されたものであ
る。 This design was devised with the aim of reducing the space required when folded by providing a specific bend on the bridge in the middle of the front, while also automatically restoring it to its normal shape when worn.
(考案の構成)
第1図は本案を実施した眼鏡ブリツジの要部横
断面図で第2図は使用状態を示す図である。(Structure of the invention) Fig. 1 is a cross-sectional view of the main part of a spectacle bridge in which the invention is implemented, and Fig. 2 is a view showing the state of use.

す。 In the drawing, 1 is the bridge of the glasses, 2 and 2 are the dividing parts provided near the middle part of the bridge, and the left and right dividing parts are aligned with the vertical axis 3.
A leaf spring 4 is stretched and fixed on the outer surface of both divided parts 2, 2, and the end face of the divided part on one side is a straight plane A perpendicular to the vertical axis 3, and the end face of the divided part on the other side is A linear surface a that is in contact with the linear surface A, a circular arc surface b that is centered on the vertical axis 3, and a linear surface c that extends in a tangential direction from the circular arc surface are formed adjacent to each other in this order. Note that 1 = length between the axis center and the circular arc surface b,
1' = indicates the length between the axis and the straight line c outside the circular arc surface.

The bridge is held in a straight line by the elasticity of the leaf spring 4 while Aa is in contact with each other, but when the glasses are removed and stored in the glasses case, the split part is bent.
Since it is bent in the shape of a letter, it can be accommodated in an eyeglass case 11 of normal thickness as shown in FIG.
分割部がない場合は特製の厚いケース12を必
要とし、無理に普通のケースに押込むと眼鏡枠の
フロントが変形、破損するおそれがある。 If there is no split part, a specially made thick case 12 is required, and if it is forced into an ordinary case, the front of the eyeglass frame may be deformed or damaged.

本案ブリツジを有する眼鏡は、前記のように屈
伸自在での折曲時のかさが低くなるのでケースは
薄手のものでもよく、ポケツトに収容した場合に
も不体裁を招かない等の効果がある。 In addition, since the end faces of the bridge divided portions are formed as shown in Fig. 1, when the divided portions are bent, the circular arc surface b rotates without loosening along the straight line plane A, and the straight line c
When it comes into contact with the straight plane A, the bending is stopped because 1'>1. (Acts as a stopper.) As mentioned above, glasses with the bridge of the present invention are flexible and have a low bulk when folded, so the case may be thin and the case will not be unsightly even when stored in a pocket. It has the effect of not inviting people.
