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).

最近、メタル製眼鏡フレームが多用される様に
なつてきたが、この種の眼鏡の耳がけ弦は細くて
一様に硬い金属帯板で製作されていたので柔軟性
に乏しく、着用した際耳がけ弦が耳肌部分を強く
圧迫し、痛いばかりか時には耳肌部分が赤くはれ
る等の事態が生じ、長時間の着用に苦痛が伴うこ
とが少くなかつた。 Recently, metal eyeglass frames have come into widespread use, but since the ear strings of these types of glasses are made of thin, uniformly hard metal strips, they lack flexibility, and when worn, the The hanging strings put strong pressure on the ear skin, which not only caused pain but also sometimes caused the ear skin to become red and swollen, and it was often painful to wear it for long periods of time.

又、この種の眼鏡においては、眼鏡着用に伴な
う耳がけ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, in this type of glasses, the force acting on the ear strings when wearing the glasses tends to concentrate on the hinge and its base, causing the temples of the glasses to warp over a long period of time. This may cause the glasses to fall off or the hinges to be damaged.

そこで、出願人はこれ等の問題点を解消する為
に実願昭55−120344号を提案した。 Therefore, the applicant proposed Utility Model Application No. 120344/1983 to solve these problems.

ところが、この方法によると前述の諸欠点は解
消できるものの、製作が困難でコスト高になる欠
点があることが判明した。 However, although this method can eliminate the above-mentioned drawbacks, it has been found that it is difficult to manufacture and increases costs.

この考案は、製作が非常に簡単であると共に、
逆反りや破損が少く、使用感がソフトな耳がけ弦
を提供しようとするもので、一実施例を図面につ
き詳述すると下記の如きものである。 This idea is very easy to manufacture and
The purpose is to provide a string for the ear that is less likely to warp or break and has a soft feel when used.One embodiment is described in detail with reference to the drawings as follows.

１はこの考案に係る耳がけ弦で、焼入等の熱処
理により適当な硬さと強靭性を有する細幅金属板

前記両弦部の間隙７とバネ板６上に角パイプ状の
細幅管８を嵌挿し、前記細幅管と後方弦部３の左
端をろう付け固着し、前方弦部２の右端は細幅管
８内に位置して移動自在に構成したものである。 Reference numeral 1 is a string for hanging ears according to this invention, which is made of a narrow metal plate that has appropriate hardness and toughness through heat treatment such as quenching, and is divided into a front string part 2 and a rear string part 3. A hinge 4 is fixed to the inside of the left end by an appropriate method, such as brazing, and the right end of the rear string part 3 is slightly curved downward, and at the same time, this part is coated with synthetic resin to form the ear hook part 5. Then, between the right end of the front string section and the left end of the rear string section 3, a V-shaped spring plate 6 as shown in FIG. fixed to
A rectangular narrow tube 8 is fitted into the gap 7 of both string sections and onto the spring plate 6, and the left end of the narrow tube and the rear string section 3 are brazed and fixed, and the right end of the front string section 2 is connected to the narrow tube. It is located within the width tube 8 and is 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７を形成させた
状態でＶ形バネ板６により両弦部を連結し、前記
間隙とバネ板６上に細幅管８を嵌挿させ、該細幅
管と後方弦部３の右端をろう付け固着すると同時
に前方弦部２の右端は何ら固着することなく細幅
管８内に位置させたので、バネ板６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 6 with a slight gap 7 formed between the right end of the front string part 2 and the left end of the rear string part 3. A narrow tube 8 is fitted onto the spring plate 6, and the right end of the narrow tube and the rear string section 3 are brazed and fixed, and at the same time, the right end of the front string section 2 is positioned within the narrow tube 8 without being fixed in any way. As a result, both the front and rear string sections 2 and 3 can be elastically deformed in the direction of the arrow in the figure, centering on the bottom of the spring plate 6.

この考案の耳がけ弦は上述の如きものであつて
先に提案したものに比べ、弦の一部をＶ形に切除
して薄肉部を構成させる必要がなく、従つて、耳
がけ弦の製作が簡単に行えるのみならず低コスト
で作ることができる実用的効果を生じる。 The ear string of this invention is as described above, and compared to the one proposed earlier, there is no need to cut out a part of the string in a V shape to form a thin part, and therefore it is easier to manufacture the ear string. It produces practical effects that are not only easy to perform but also can be produced at low cost.

なお、この様な耳がけ弦を左右対称状に一対製
作し、これを眼鏡フレーム（図示せず）に取付け
てなる眼鏡は、弦全体が一様に硬く構成されてい
て弾性変形しない従来の耳がけ弦に比し、着用時
頭部側面にぴつたり合つて使用感が非常にソフト
で良好であるばかりか、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、
蝶番部が破損したりしない。 In addition, glasses made by manufacturing a pair of such ear strings symmetrically and attaching them to an eyeglass frame (not shown) are different from conventional ear strings in which the entire string is uniformly hard and does not deform elastically. Compared to hanging strings, it not only fits snugly against the side of the head when worn, making it very soft and comfortable to use, but also because force is not concentrated on the hinge and its base, even when worn for a long period of time, the temple part will not be affected. No reverse warping occurs, and it does not slip off when worn,
The hinge part will not be damaged.

又、耳がけ弦上の細幅管は弦のアクセサリーと
なつて眼鏡の意匠的美感を向上する。 In addition, the narrow tube on the ear string becomes an accessory for the string and improves the aesthetic design of the glasses.
