Description

【考案の詳細な説明】 この考案は、眼鏡の耳がけ弦（以下耳がけ弦と
いう）の改良に関するものである。[Detailed description of the invention] This invention relates to the improvement of ear strings for glasses (hereinafter referred to as ear strings).

セル枠と称するセルロイド製の眼鏡では、金属
製芯材にセルロイドを被覆した耳がけ弦を使用す
るが、耳がけ弦の柔軟性が乏しい為、この種の眼
鏡を着用した際、耳がけ弦が耳肌部分を強く圧迫
し、長時間の着用に苦痛を伴うことが少くなく、
両耳がけ弦の拡開度を適度に調整する必要がある
が、この調整は素人にはできず、大へん不便であ
つた。 Celluloid eyeglasses, called cell frames, use ear strings that have a metal core coated with celluloid.However, because the ear strings have poor flexibility, when wearing this type of glasses, the ear strings may become loose. They put strong pressure on the ear skin and are often painful to wear for long periods of time.
It was necessary to appropriately adjust the degree of expansion of the strings for both ears, but this adjustment was not possible for amateurs and was very inconvenient.

又、この種の眼鏡においては、眼鏡着用に伴な
う弦に作用する力が蝶番部及びその基部に集中す
る傾向があり、長期にわたる使用によつて眼鏡の
テンプル部分が逆反りし、眼鏡がずり落ちたり、
蝶番部が破損する原因となつている。 In addition, with this type of glasses, the force acting on the strings when wearing the glasses tends to concentrate on the hinge and its base, causing the temples of the glasses to warp and cause the glasses to warp over a long period of time. Fall down or
This causes damage to the hinge part.

この考案は、逆反りしたり、破損したりせず、
又、両弦の拡開度を調整する必要もない使用感の
ソフトな耳がけ弦を提供しようとするもので、一
実施例を示せば次の通りである。 This idea does not warp or break,
Furthermore, the present invention aims to provide a string for listening to the ear that is soft to the touch and does not require adjustment of the degree of expansion of both strings.One embodiment is as follows.

１はこの考案に係る耳がけ弦で、セルロイドか
ら製作された前方弦部２と後方弦部３とからな

左端内側には蝶番５が突設され、後方弦部３は内
部に金属芯材６が埋設し、右端には下方に湾曲し
た耳がけ部７が形成されている。 1 is an ear string according to this invention, which consists of a front string part 2 and a rear string part 3 made of celluloid, and the front string part has a metal core material 4 buried therein;
A hinge 5 is provided protruding inside the left end, a metal core 6 is embedded inside the rear string section 3, and a downwardly curved ear hook section 7 is formed at the right end.

前記前方弦部の右端と後方弦部３の左端間に

の接合部をろう付け固着し、前方弦部２の右端及
び後方弦部３の左端は細幅管１０内に位置して移
動自在に構成したものである。 Between the right end of the front string section and the left end of the rear string section 3, a V-shaped spring plate 8 as shown in FIG. Appropriate means are applied to the surface or the core materials 4 and 6, respectively.
For example, by fixing with adhesive, machine screws, brazing, etc., a square pipe-shaped narrow tube 10 is inserted between the gap 9 of both chord parts and the spring plate 8, and the narrow tube and the spring plate 8 are inserted.
The right end of the front string section 2 and the left end of the rear string section 3 are positioned within the narrow tube 10 and are configured to be movable.

この考案の耳がけ弦１は、前方弦部２の右端と
後方弦部３の左端間に若干の間隙９を形成させた

で、バネ板８の底部を中心として前後両弦部２，
３は図中矢印の方向に弾性変形が可能となる。 The ear string 1 of this invention connects both string parts with a V-shaped spring plate 8 with a slight gap 9 formed between the right end of the front string part 2 and the left end of the rear string part 3. Fitting the narrow tube 10 onto the spring plate 8, brazing and fixing the joint between the narrow tube and the spring plate 8, and simultaneously fixing the right end of the front string section 2 and the left end of the rear string section 3 in any way. Since it is located inside the narrow tube 10 without any distortion, both the front and rear chord parts 2, centering on the bottom of the spring plate 8,
3 can be elastically deformed in the direction of the arrow in the figure.

この考案の耳がけ弦は上述の如きもので、この
様な耳がけ弦１を左右対称状に一対製作し、これ

し、又、蝶番とその基部に力が集中しないから長
期間の着用によつてもテンプル部分の逆反りが発
生せず、着用時にずり落ちたり、蝶番部が破損し
ない。 The ear strings of this invention are as described above, and a pair of such ear strings 1 are made symmetrically, and these are attached to an eyeglass frame (not shown) to produce glasses. It deforms flexibly without adjusting the expansion circle, and when worn, it fits perfectly against the side of the head, making it comfortable to use, and it does not cause any pain even when worn for a long time, and the force is concentrated on the hinge and its base. Because it does not, the temple part will not warp even if worn for a long period of time, and the temple part will not fall off or the hinge part will be damaged when worn.

なお、耳がけ弦上の細幅管はアクセサリーとな
つて、眼鏡の意匠的美感を向上する。 The narrow tubes on the ear strings serve as accessories and improve the aesthetic design of the glasses.
