Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、衣服又は収納袋の開口部回りに配置されている紐の端部分に取り付けられる紐類の端部カバーに関するものである。
【０００２】
【従来の技術】
紐類のうち、本発明を適用した図７に例示される如く衣類の胴部や衿回り、又は収納袋の開口部回り用いられる紐１等では、同図に図示されていないが、紐１の両側部分に結び部を作っておき、その結び部を掴んで引き寄せ易くしたり、衣類や収納袋側の配置部から不用意に抜けないようにしている。また、そのような紐類には、従来から、筒状の端部カバーを用いて、紐の端部分をカバー入口側から出口側に挿通した状態で、前記した結び部を作った後、紐をカバーから抜け方向に引っ張ることで結び部を含む紐の端部分をその端部カバー内に収納して、外観処理を施すことも行われている。本発明はその端部カバーを対象にしている。
【０００３】
【発明が解決しようとする課題】
従来の端部カバーは、出口側内径を入口側内径より大きくして段差を付けた単純な略筒状のものが多く、次のような点等で充分に満足できないものであった。
第１に、紐の端末処理的には、紐の結び部をカバー内の段差を介在して抜け止めしているだけなので、紐の端部分が樹脂カバーの出口側から飛び出し易く取付状態を維持できなくなる。
第２に、装飾機能的には、筒内に入れられた紐の端部分がカバー出口側の開口から見えることから、使用状態での見栄えが悪い。そこで、この改善策としては、出口側の筒部を長くして内部を見え難くすることもあるが、根本的な対策にはならない。
第３に、前記したような各不具合の対策として、例えば、カバーの出口側に蓋部材を装着することも考えられる。しかし、そのような蓋部材は、カバーから不用意に外れて無くなったり、取扱性に欠けるばかりでなく、対応する成形型も必要となる。なお、この種のカバーは紐類用であることから全体が小さく、衣類用のケースでは外径が５〜１０ｍｍ、全長が１０〜１５ｍｍの仕様となることも多い。このため、蓋部材を用いる場合、本体部への装着構造として、例えば、外観性を損なわずに取付強度を増大し難くいと言うように、新たな問題が発生する。
【０００４】
本発明は上記した背景に鑑みてなされたものである。第１の目的はカバーが蓋を有する構造において、蓋がカバーから不用意に外れても無くなる虞を構造的に防ぐことができると共に、取扱性および成形性に優れた紐類の端部カバーを提供することにある。第２の目的は全体が小さな場合にも、外観性を損なうことなく蓋の取付強度を大きくでき、また外観性も良好に維持することができるようにすることにある。更に他の目的は、以下に説明する内容の中で明らかにする。
【０００５】
【課題を解決するための手段】
上記目的を達成するため本発明は、図面に例示される如く、衣服や収納袋等に設けられている紐１の端部分１ａに対し、端部分１ａを内部に入れて抜け止め状態に取り付けられる端部カバー１０において、出口１１ｂ側内径を入口１１ａ側内径より大きくした略筒状の本体部１１と、本体部１１の出口１１ｂ側に薄肉ヒンジ片部１５を介して一体に形成されて、出口１１ｂ側を閉じると同時に係合して装着される蓋部２０とからなると共に、
前記薄肉ヒンジ片部１５は、一端側１５ａが前記蓋部２０の外周に連結され、他端側が前記本体部１１の出口側外周１１ｃにあって端面１２ｂから該本体部の入口１１ａに向かって設けられた欠肉部１４内に位置し、かつ本体部外周と連続した状態に設けられており、
前記本体部１１に対し前記紐１がその端部分１ａを前記入口１１ａから前記出口１１ｂの外へ引き出し、該引き出した端部分に作られる結び目２を該本体部内に入れた状態で該結び目を介して抜け止めされ、かつ、前記蓋部２０を前記薄肉ヒンジ片部１５を介して回転し装着することで前記結び目２の前記出口外への飛び出しを防止可能にしたものである。
【０００６】
この構造によれば、端部カバー１０の装着操作では、蓋部２０の開状態から、紐１の端部分１ａを本体部１１の入口１１ａから出口１１ｂに通しておき、その出口１１ｂ外へ引き出された端部分１ａに結び部２を形成する。次に、紐１を入口１１ａに引いて結び部２を含む端部分１ａを本体部１１内に入れる。その後、蓋部２０は、薄肉ヒンジ片部１５を介して本体部１１の出口１１ｂの端面１２ｂに押し当てると、その出口１１ｂを閉じると同時に係合して装着される。
したがって、この端部カバー１０は、本体部１１の出口１１ｂを蓋部２０にて閉じるようにしたことから、従来品の如く紐１の端部分１ａが本体部１１の出口１１ｂから飛び出すということを防いで、紐１に対する取付状態を構造的に保ち、同時に、本体部１１の出口１１ｂ側における見栄えも向上することができる。これに加え、蓋部２０は、本体部１１に対し薄肉ヒンジ片部１５を介して連結されていることから、本体部１１から不用意に外れても本体部１１より落ちる等して無くなると言うような虞がなく、また本体部１１と一体物として取り扱うことが可能となる。薄肉ヒンジ片部１５としては、以下の形態例の如く、一端側１５ａが蓋部２０の外周に連結されている共に、他端側１５ｂが本体部１１の出口１１ｂ側外周１１ｃに端面１２ｂから入口１１ａに向かって設けられた欠肉部１４内に位置し、かつ本体部外周１１ｃと連続した状態で形成されているため、蓋部２０の閉じ状態で薄肉ヒンジ片部１５を本体部外周１１ｃから突出させずに外観的により良好となる。
ここで、端部カバー１０が適用される紐類としては、各種の身回り品、バック等の収納袋等に設けられる紐を意味し、通常、衣服の胴部や衿回り又は収納袋の開口部回りに配置されている紐が対象となる。
【０００７】
以上の本発明は次のように具体化されることがより好ましい。
すなわち、前記本体部１１の出口内周は、対向する部分に設けられた対の平面部１２ｅと、前記平面部を除く内周部分に設けられた係止突起１３とを有し、前記蓋部２０は、内面に突出して前記本体部１１の出口に差し込まれる枠状の挿入脚部２２と、前記挿入脚部の両側の枠部分に設けられた円弧状の片部２３および前記片部の先端外周に形成した係止突部２３ａと、前記挿入脚部の前後の枠部分に設けられた凸部２４ａとを有し、前記蓋部２０を閉じ方向へ押圧することにより蓋部側の係止突部２３ａが前記本体部側の係止突部１３を弾性的に乗り越えて係合すると同時に、前記凸部２４ａが前記平面部１２ｅに圧接する構成である。これは、端部カバー１０が外径５〜１０ｍｍ、全長１０〜１５ｍｍと小さくなる場合、蓋部２０の本体部１１に対する係合力ないしは蓋部２０の取付強度を外観を損なわずに増大する上で好適なものとして採用された構造である。要は、各種の係合構造について比較試験し完成されたもので、例えば、蓋部２０側に設けた係止突起を本体部１１の内周に設けた凹部に弾性的に係合するような構成等に比して係合力をより大きくすることが可能となる。
【０００８】
【発明の実施の形態】
以下、本発明の好適な形態を添付図面に基づいて詳細に説明する。なお、以下に述べる形態は、本発明の好適な具体例であるから技術的に好ましい種々の限定が付されている。しかし、本発明の範囲はこれらの形態に限られるものではない。
【０００９】
図１乃至図７は本発明に係る紐類の端部カバーを示し、図１は紐への取付要領と装着状態を示す縦断側面図、図２は端部カバー単品を蓋部を開状態で示す外観図、図３は端部カバー単品を蓋部を閉じ状態で示し、図３（ａ）は正面図、図３（ｂ）は背面図、図３（ｃ）は上面図、図３（ｄ）は下面図である。図４（ａ）は図３（ａ）のＡ−Ａ線断面図、図４（ｂ）は図３（ｃ）のＢ−Ｂ線断面図、図４（ｃ）は側面図である。また、図５と図６は蓋部を開状態で示し、図５（ａ）はその上面図、図５（ｂ）は図６（ａ）のＥ部の拡大図、図６（ａ）は図５（ａ）のＣ−Ｃ線断側面図、図６（ｂ）は図５（ａ）のＤ−Ｄ線断側面図である。図７は端部カバーを使用している状態で示す外観図である。
【００１０】
図１乃至図７において、端部カバー１０は樹脂成形品であり、適用される紐１に対応して設計されて、長さ寸法が約１３ｍｍで、最大径が約１０ｍｍという比較的小さなものである。外観的には、略筒状の本体部１１を主体とし、本体部１１の出口１１ｂ側に薄肉ヒンジ片部１５を介在して設けられた蓋部２０を有しており、使用状態で出口１１ｂが蓋部２０により閉じられる。
【００１１】
ここで、本体部１１は、外周１１ｃを入口１１ａ側から出口１１ｂ側に向かって次第に大きく形成した筒状をなしている。内周には、入口１１ａの端面１２ａから約２ｍｍの長さ位置迄を厚肉部１２ｃに形成し、その厚肉部１２ｃの内径Ｌ1が出口１１ｂ側の内径Ｌ2よりも小さくなっており、肉厚部１２ｃの奥側端面に相当する段差１２ｄを有している。出口１１ｂ側の内周には、円内面の対向する部分を平にした平面部１２ｅが対に設けられていると共に、平面部１２ｅを除く内周部分に係止突起１３が設けられている。平面部１２ｅ同士の間の寸法は他の端面１２ｂ側の内径よりも少しだけ小さくなっている。係止突起１３は、端面１２ｂ側に位置し平面部１２ｅを除く内周部分に長いリブ状に形成されている。本体部１１の出口１１ｂ側の外周１１ｃには薄肉ヒンジ片部１５が一体に突出形成されている。
【００１２】
薄肉ヒンジ片部１５は、一端側１５ａが蓋部２０の外周に一体化されており、他端側１５ｂが出口１１ｂ側の外周１１ｃに設けられた欠肉部１４から延びている。つまり、この欠肉部１４は、図５（ｂ）に示される如く、本体部１１の外周１１ｃにあって、端面１２ｂから入口１１ａに向かって設けられている。そして、他端側１５ｂは、欠肉部１４内の中間部に位置し、欠肉部１４の底面１４ａと隙間を保ち、かつ本体部外周１１ｃと連続した状態で形成されており、蓋部２０が閉じたときに外周１１ｃと面一になるよう設計されている。
【００１３】
蓋部２０は、薄肉ヒンジ片部１５の一端側１５ａとその外周縁部に連結している。また、蓋部２０は、本体部１１の端面１２ｂと略同じ外径をなし、内面２１に突出されて出口１１ｂに差し込まれる枠状の挿入脚部２２を有している。この挿入脚部２２の両側の枠部分は出口１１ｂの内径Ｌ2に対応した円弧状の片部２３を構成し、その先端外周に係止突部２３ａを形成している。挿入脚部２２の前後の枠部分２４は平行になっていて、その枠部分２４の外面中間に凸部２４ａを形成している。係止突部２３ａは、蓋部２０を閉じる過程で係止突部１３を弾性的に乗り越えて係合する。つまり、係止突部２３ａと係止突部１３とは第１の係合手段を構成している。凸部２４ａは、内面２１に向けて外側へ張り出すテーパーに形成されており、蓋部２０の閉じる過程でテーパーによるガイド作用を経て平面部１２ｅに圧接する。つまり、凸部２４ａと平面部１２ｅとは第２の係合手段を構成している。したがって、以上の蓋部２０は、本体部１１の出口１１ｂに対し前記した第１と第２の係合手段により大きな固定強度で取り付けられる。
【００１４】
以上のように構成された端部カバー１０は、図７に例示される如く、衣服等に組み込まれた紐１の両側の端部分１ａに取り付けられる。この取付要領は、図１（ａ）に示す如く蓋部２０の開状態から、紐１の端部分１ａを本体部１１の入口１１ａから出口１１ｂに通し、その出口１１ｂ外へ引き出された端部分１ａに結び部２を形成した後、紐１を入口１１ａに引っ張ることにより結び部２を含む端部分１ａを本体部１１内に入れる。すると、端部分１ａは、図１（ｂ）に示す如く結び部２が段差１２ｄに当接した状態で、全体が本体部１１内に収納される。この収納状態から、蓋部２０を閉じる。この場合は、蓋部２０を薄肉ヒンジ片部１５を介して回転し、端面１２ｂに対し押し当てるようにする。蓋部２０は、内面２１が端面１２ｂに当接する直前の段階で、各片部２３と枠部分２４が出口１１ｂに入り込み、次の段階で係止突部２３ａが係止突部１３を弾性的に乗り越えると同時に、凸部２４ａが平面部１２ｅに圧接し、出口１１ｂ側を閉じた状態で所定強度にて係止される。
【００１５】
したがって、この形態の端部カバー１０にあっては、本体部１１の出口１１ｂが蓋部２０にて閉じられることから、紐１の端部分１ａが本体部１１の出口１１ｂから不用意に飛び出すということが構造的になくなる。つまり、端部カバー１０は、紐１への取付状態が常に保たれ、出口１１ｂの見栄えを向上することができる。しかも、この蓋部２０の構造では、本体部１１に薄肉ヒンジ片部１５を介して連結されているので、蓋部２０が本体部１１から不用意に外れても落ちる等して無くなると言うことがなくなること、蓋専用の成形型を必要としないこと、本体部１１と一体物として取り扱うことができること、上記した第１と第２の係合手段により本体部１１に対する係合力を大きく付与できること、等の利点がある。更に、薄肉ヒンジ片部１５は、一端側１５ａが蓋部２０の外周縁部に連結されていることに加え、他端側１５ｂが欠肉部１４内に位置して外周１１ｃと連続した状態に形成されているため、蓋部２０を閉じた状態では薄肉ヒンジ片部１５の略全体が外周１１ｃの欠肉部１４内に位置し、外周１１ｃと面一になることから、見栄えが良好となる。
【００１６】
なお、上記形態の端部カバー１０は、装飾機能も重視されることから、全面にシボ加工が施されたり、外周１１ｃ等に彫刻等で装飾処理されることもある。また、本体部１１や蓋部２０の基本形状は、この形態に限られず、例えば、断面多角形に形成することも可能である。また、端部カバー１０の用途ないしは使用される箇所は、上記した形態に限ることなく、各種の部材や部分に設けられる紐１の端部分１ａに取り付けられるものである。
【００１７】
【発明の効果】
以上説明したとおり、本発明に係る紐類の端部カバーは、本体部に対し蓋部を薄肉ヒンジ片部を介して一体に形成していることから、従来品の如く紐の端部分が本体部の出口から飛び出すということを構造的に防いで、紐への取付状態を確実に維持でき、本体部出口側の見栄えを向上できることを前提とし、蓋部が本体部から不用意に外れても落ちる等して無くなると言うような虞がなく、しかも蓋部付きの本体部として常に一体物となっているので、取扱性や蓋部の閉じ操作性に優れている。これにより、この種の端部カバーの信頼性を向上できると共に、用途的にも拡大することが期待できる。

BACKGROUND OF THE INVENTION
The present invention relates to an end cover of a string attached to an end portion of a string arranged around an opening of a garment or a storage bag, for example.
[0002]
[Prior art]
Among the laces, as shown in FIG. 7 to which the present invention is applied, the lace 1 used around the trunk of the garment, around the heel, or around the opening of the storage bag is not shown in FIG. The knots are made on both sides of the bag so that the knots can be easily gripped and pulled out, and the knots cannot be inadvertently removed from the arrangement part on the clothing or storage bag side. In addition, for such cords, conventionally, a tubular end cover is used, and after the end portion of the cord is inserted from the cover entrance side to the outlet side, The end portion of the string including the knot portion is housed in the end portion cover by pulling the cover in the pulling direction, and appearance processing is performed. The present invention is directed to that end cover.
[0003]
[Problems to be solved by the invention]
Many of the conventional end covers have a simple substantially cylindrical shape with a step formed by making the inner diameter on the outlet side larger than the inner diameter on the inlet side, and are not fully satisfactory in the following points.
First, in terms of the end processing of the string, since the knot portion of the string is only prevented from coming off via a step in the cover, the end portion of the string is easily popped out from the outlet side of the resin cover, and the attached state is maintained. become unable.
Second, in terms of decorative function, the end portion of the string placed in the cylinder is visible from the opening on the cover outlet side, so that the appearance in use is poor. Therefore, as an improvement measure, the tube portion on the exit side may be lengthened to make it difficult to see the inside, but this is not a fundamental measure.
Thirdly, as a countermeasure against the above-described problems, for example, it is conceivable to attach a lid member to the outlet side of the cover. However, such a lid member is not only inadvertently removed from the cover and is not easy to handle, but also requires a corresponding mold. In addition, since this kind of cover is for strings, the whole is small, and in the case for clothing, the outer diameter is often 5 to 10 mm and the total length is 10 to 15 mm. For this reason, when using a lid member, a new problem arises, for example, that it is difficult to increase the mounting strength without impairing the appearance as a structure for mounting to the main body.
[0004]
The present invention has been made in view of the above-described background. The first object is to provide a structure having a cover with a cover, which can structurally prevent the cover from being lost even if it is inadvertently removed from the cover. It is to provide. The second object is to make it possible to increase the mounting strength of the lid without deteriorating the appearance, and to maintain good appearance even when the whole is small. Still other objects will be clarified in the contents described below.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, as illustrated in the drawings, the present invention is attached to an end portion 1a of a string 1 provided in clothes, a storage bag or the like by putting the end portion 1a inside and preventing it from coming off. In the end cover 10, a substantially cylindrical main body portion 11 having an inner diameter on the outlet 11 b side larger than an inner diameter on the inlet 11 a side, and the outlet 11 b side of the main body portion 11 are integrally formed via a thin hinge piece 15. Close 11b side at the same time engage with a lid portion 20. is mounted Rutotomoni,
The thin-walled hinge piece 15 has one end side 15a connected to the outer periphery of the lid part 20, and the other end side provided on the outer periphery 11c of the main body part 11 and provided from the end surface 12b toward the inlet 11a of the main body part. Is provided in a state where it is located in the hollow portion 14 and is continuous with the outer periphery of the main body,
The string 1 with respect to the main body 11 draws the end portion 1a from the inlet 11a to the outside of the outlet 11b, and the knot 2 formed on the drawn end portion is inserted into the main body through the knot. The lid 20 is rotated and attached via the thin hinge piece 15 so that the knot 2 can be prevented from jumping out of the outlet.
[0006]
According to this structure, in the mounting operation of the end cover 10, the end portion 1 a of the string 1 is passed from the inlet 11 a of the main body 11 to the outlet 11 b from the opened state of the lid portion 20, and pulled out of the outlet 11 b. A knot 2 is formed at the end portion 1a. Next, the string 1 is pulled to the entrance 11 a and the end portion 1 a including the knot portion 2 is put into the main body 11. Thereafter, when the lid 20 is pressed against the end surface 12b of the outlet 11b of the main body 11 through the thin hinge piece 15, the lid 20 is engaged and mounted at the same time as the outlet 11b is closed.
Therefore, the end cover 10 is configured such that the end portion 1a of the string 1 jumps out from the outlet 11b of the main body portion 11 as in the conventional product because the outlet 11b of the main body portion 11 is closed by the lid portion 20. Thus, the attachment state to the string 1 can be structurally maintained, and at the same time, the appearance of the main body 11 on the outlet 11b side can be improved. In addition, since the lid 20 is connected to the main body 11 via the thin hinge piece 15, the lid 20 is lost from the main body 11 even if it is carelessly removed from the main body 11. There is no such a concern, and the main body 11 can be handled as an integral part . As the thin hinge piece 15, one end side 15 a is connected to the outer periphery of the lid portion 20 and the other end side 15 b enters the outlet 11 b side outer periphery 11 c of the main body 11 from the end surface 12 b as shown in the following embodiment. The thin hinge piece 15 is located from the outer periphery 11c in the closed state of the lid portion 20 because it is located in the lacking portion 14 provided toward 11a and is continuous with the outer periphery 11c of the main body. Appearance is better without protruding.
Here, the string to which the end cover 10 is applied means a string provided in various personal belongings, a storage bag such as a bag, etc. The string arranged around the part is the target.
[0007]
The present invention as described above is more preferably embodied as follows.
That is, the inner periphery of the outlet of the main body 11 has a pair of flat portions 12e provided at opposing portions, and a locking projection 13 provided at an inner peripheral portion excluding the flat portion, and the lid portion. Reference numeral 20 denotes a frame-shaped insertion leg portion 22 that protrudes from the inner surface and is inserted into the outlet of the main body portion 11; an arc-shaped piece portion 23 provided at the frame portions on both sides of the insertion leg portion; a locking projection 23a formed on the outer peripheral, and a convex portion 24a provided on the front and rear frame portions of the insertion leg portion, the engagement of the lid side by pressing the closing direction the lid 20 at the same time retaining projection 23a is engaged with the locking projection 13 of the main body portion side get over elastically, a configuration in which the convex portion 24a is pressed against the flat portion 12e. This is because when the end cover 10 is reduced to an outer diameter of 5 to 10 mm and a total length of 10 to 15 mm, the engagement force of the lid portion 20 with respect to the main body portion 11 or the attachment strength of the lid portion 20 is increased without impairing the appearance. This is a structure adopted as a preferable one. In short, various engagement structures have been comparatively tested and completed. For example, the engagement protrusion provided on the lid 20 side is elastically engaged with the recess provided on the inner periphery of the main body 11. It is possible to increase the engagement force as compared with the configuration and the like.
[0008]

Moreover, the cover part 20 has substantially the same outer diameter as the end surface 12b of the main body part 11, and has a frame-shaped insertion leg part 22 that protrudes from the inner surface 21 and is inserted into the outlet 11b. The frame portions on both sides of the insertion leg 22 constitute an arcuate piece 23 corresponding to the inner diameter L2 of the outlet 11b, and a locking projection 23a is formed on the outer periphery of the tip. The front and rear frame portions 24 of the insertion leg portion 22 are parallel to each other, and a convex portion 24 a is formed in the middle of the outer surface of the frame portion 24. The locking protrusion 23 a elastically climbs over the locking protrusion 13 in the process of closing the lid 20 and engages. That is, the locking projection 23a and the locking projection 13 constitute first engaging means. The convex part 24a is formed in a taper projecting outward toward the inner surface 21, and presses against the flat surface part 12e through a guide action by the taper in the process of closing the lid part 20. That is, the convex part 24a and the plane part 12e comprise the 2nd engagement means. Therefore, the lid 20 described above is attached to the outlet 11b of the main body 11 with a large fixing strength by the first and second engaging means described above.
[0014]
The end cover 10 configured as described above is attached to the end portions 1a on both sides of the string 1 incorporated in clothes or the like as illustrated in FIG. As shown in FIG. 1 (a), this attachment procedure is such that the end portion 1a of the cord 1 is passed from the inlet 11a of the main body 11 to the outlet 11b and is pulled out of the outlet 11b from the open state of the lid portion 20. After the knot portion 2 is formed on 1a, the end portion 1a including the knot portion 2 is put into the main body portion 11 by pulling the string 1 to the inlet 11a. Then, the entire end portion 1a is housed in the main body portion 11 with the knot portion 2 in contact with the step 12d as shown in FIG. From this stored state, the lid 20 is closed. In this case, the lid 20 is rotated via the thin hinge piece 15 and pressed against the end face 12b. At the stage immediately before the inner surface 21 comes into contact with the end surface 12b, the cover part 20 enters each outlet 23 and the frame part 24 into the outlet 11b, and the locking projection 23a elastically locks the locking projection 13 at the next stage. At the same time, the convex portion 24a comes into pressure contact with the flat surface portion 12e and is locked at a predetermined strength with the outlet 11b side closed.
[0015]
Therefore, in the end cover 10 of this form, since the outlet 11b of the main body 11 is closed by the lid portion 20, the end portion 1a of the string 1 jumps out of the outlet 11b of the main body 11 inadvertently. Is structurally lost. That is, the end cover 10 is always attached to the string 1 and can improve the appearance of the outlet 11b. In addition, in the structure of the lid portion 20, the lid portion 20 is connected to the main body portion 11 via the thin hinge piece portion 15, so that even if the lid portion 20 is inadvertently removed from the main body portion 11, it is lost. The need for a special mold for the lid, the ability to handle the main body 11 as an integral object, the ability to apply a large engagement force to the main body 11 by the first and second engaging means described above, There are advantages such as. Further, the thin hinge piece 15 has one end side 15a connected to the outer peripheral edge of the lid portion 20, and the other end side 15b is located in the lacking portion 14 and is continuous with the outer periphery 11c. Therefore, when the lid 20 is closed, the thin hinge piece 15 is almost entirely located in the lacking portion 14 of the outer periphery 11c and is flush with the outer periphery 11c. .
[0016]
Note that the end cover 10 of the above-described form also places emphasis on the decoration function, so that the entire surface may be textured or the outer periphery 11c or the like may be decorated by engraving or the like. In addition, the basic shapes of the main body 11 and the lid 20 are not limited to this form, and can be formed, for example, in a polygonal cross section. Moreover, the use of the end cover 10 or the place where it is used is not limited to the above-described form, but is attached to the end portion 1a of the string 1 provided on various members and portions.
[0017]
【The invention's effect】
As described above, the end cover of the cords according to the present invention integrally forms the lid portion with respect to the main body portion through the thin hinge piece portion, so that the end portion of the string is the main body as in the conventional product. It is structurally prevented from jumping out of the exit of the part, it can be reliably maintained in the attachment state to the string, and it is possible to improve the appearance of the body part outlet side, even if the lid part is inadvertently removed from the body part There is no fear that it will disappear due to falling, etc., and since it is always an integral body as a main body with a lid, it is excellent in handleability and closing operation of the lid. As a result, the reliability of this type of end cover can be improved, and it can be expected to expand in terms of applications.
