Description

【考案の詳細な説明】 〔産業上の利用分野〕 この考案は眼鏡枠に関するものである。[Detailed explanation of the idea] [Industrial application field] This invention relates to eyeglass frames.

〔従来の技術及びその問題点〕[Conventional technology and its problems]

眼鏡枠における左右の両レンズ枠は、テンプル
を耳にかけることによつて顔面にフイツトさせ
る。 Both the left and right lens frames in the eyeglass frame are fitted to the face by placing the temples over the ears.

しかしながら、テンプルをこめかみに圧接状に
修正しても、両レンズ枠が眼球から離れる方向に
次第に変形することがあつて、眼鏡を常時顔面に
フイツトさせることは困難である。 However, even if the temples are pressed against the temples, both lens frames gradually deform in the direction away from the eyeballs, making it difficult to keep the glasses always fitted to the face.

この考案は上記の問題点を解決しようとするも
ので、その目的とするところはテンプルが常に顔
側に寄る復元性ある眼鏡枠とするにある。 This invention is an attempt to solve the above-mentioned problems, and its purpose is to create a resilient eyeglass frame in which the temples are always closer to the face.

〔問題点を解決するための手段〕[Means for solving problems]

上記の問題点を解決するために、この考案は左
右の両レンズ枠を連結するブリツジを両レンズ枠
に対し前後に屈曲自在に連結し且つ前記ブリツジ
の裏面側に中央部を固定した板ばねの両端を、レ
ンズ枠の前記ブリツジへの連結部に形成した背面
側且つ外周部への突出角部に背面側から圧接して
両レンズ枠に常時背面側に屈曲する復元性を付与
した眼鏡枠としたものである。 In order to solve the above problems, this invention uses a plate spring that connects the bridge that connects both the left and right lens frames so that it can be bent back and forth with respect to both lens frames, and that the center part is fixed to the back side of the bridge. An eyeglass frame whose both ends are pressed from the back side to a protruding corner portion formed at the connecting portion of the lens frame to the bridge and projecting from the back side to the outer circumferential portion, thereby giving both lens frames a restorability of constantly bending toward the back side. This is what I did.

〔実施例〕〔Example〕

第１図は本考案に係る眼鏡枠の一例の背面図で
あり、１は左右の両レンズ枠、２は両レンズ枠を
連結するブリツジ、３はテンプルである。 FIG. 1 is a rear view of an example of a spectacle frame according to the present invention, where 1 is both left and right lens frames, 2 is a bridge connecting both lens frames, and 3 is a temple.

ブリツジ２は拡大第２図、第４図に示すよう
に、両レンズ枠１に対し上下方向のねじ軸４によ
り前後方向に屈曲自在の連結にしてある。 As shown in enlarged views in FIGS. 2 and 4, the bridge 2 is connected to both lens frames 1 by a screw shaft 4 extending in the vertical direction so that it can be bent in the front and rear directions.

又ブリツジの背面側には板ばね５が添えられ、
その中央部をブリツジ２の中央部にリベツト６で
固定してその両端を、レンズ枠１に対しブリツジ
２を連結した位置でレンズ枠に形成した、背面側
且つ外周側への突出角部７に背面側から圧接して
いて、この状態では第５図に矢印で示すように、
レンズ枠１がねじ軸４を支点として背面側に屈曲
する復元性がある。 Also, a leaf spring 5 is attached to the back side of the bridge,
Its center part is fixed to the center part of the bridge 2 with a rivet 6, and both ends thereof are attached to the corner parts 7 that protrude toward the rear side and the outer circumferential side, which are formed on the lens frame at the position where the bridge 2 is connected to the lens frame 1. It is pressed from the back side, and in this state, as shown by the arrow in Figure 5,
The lens frame 1 has a restorability in that it is bent toward the back side using the screw shaft 4 as a fulcrum.

第６図は両レンズ枠１ａがねじ軸４（図示省
略）を支点として背面側に屈曲する復元性を更に
大とする補助機構をそなえたものを示す。即ち両
レンズ枠１ａには上枠部に短尺のパイプ８が溶接
により固定してあつて対向方向に向いており、両
パイプの対向外側端は閉塞してある。 FIG. 6 shows an arrangement in which both lens frames 1a are provided with an auxiliary mechanism for further increasing the restorability of bending the lens frames 1a toward the back side using a screw shaft 4 (not shown) as a fulcrum. That is, short pipes 8 are fixed to the upper frame portions of both lens frames 1a by welding, facing in opposite directions, and the opposing outer ends of both pipes are closed.

そして、この両パイプ８，８には、同図鎖線で
示すように、緩やかな弧状に湾曲した線状ばねか
らなる副ブリツジ９の両端を、その湾曲の向きを
主ブリツジ２と同じ向き（表側に脹らむ向き）に
して嵌合支持してあつて、副ブリツジ９も両レン
ズ枠１ａを背面側に且つ両レンズ枠の対面方向へ
の復元性が付与され、主ブリツジ２の機能を更に
増大している。 As shown by the chain lines in the same figure, both ends of the sub-bridge 9 made of a linear spring curved into a gentle arc are attached to both the pipes 8, 8, with the direction of curvature in the same direction as the main bridge 2 (front side). The secondary bridge 9 is also provided with the ability to restore both lens frames 1a to the back side and in the facing direction of both lens frames, further increasing the function of the main bridge 2. ing.

〔効果〕〔effect〕

この考案の眼鏡枠としたことにより、以下に述
べるような効果がある。 The glasses frame of this invention has the following effects.

左右の両レンズ枠を連結するブリツジは両レン
ズ枠に対し前後に屈曲自在とし、又ブリツジの裏
面側には中央部をブリツジに固定した板ばねがあ
り、この板ばねの両端はレンズ枠の、ブリツジ連
結部に形成した背面側且つ外周部への突出角部に
背面側から圧接してあるので両レンズ枠に常時背
面側に屈曲しようとする復元性があつて、両レン
ズ枠を常に一定方向に寄せ、同時にテンプルも顔
の側面に寄つて顔面へのフイツテイングを常に正
常に保たせることができる。 The bridge that connects both the left and right lens frames can be bent forward and backward relative to both lens frames, and on the back side of the bridge there is a leaf spring whose center part is fixed to the bridge, and both ends of this leaf spring Since it is pressed from the back side to the protruding corner part formed on the bridge connecting part on the back side and the outer periphery, both lens frames have the resilience to always bend toward the back side, and both lens frames are always kept in the same direction. At the same time, the temples are also moved closer to the sides of the face to maintain a normal fit to the face.
