Description
本発明は、被着体の面に挿入される挿入部材であって、収納扉などの被着体の面に開口する穴に挿入して用いる目隠しキャップなどとして好適に用いられる挿入部材に関する。 The present invention relates to an insert member that is inserted into the surface of an adherend, and is suitable for use as a cover cap that is inserted into a hole that opens into the surface of the adherend, such as a storage door.
収納扉には、開閉操作用の取手を設けるために取手穴が形成されるが、扉の板厚との関係や加工の容易性から、扉の板厚を貫通するように取手穴を形成し、その表面側の開口に取手を設けることが多い。この場合、扉の裏面側において取手穴が開口したままであると、扉を開いたときに取手穴の裏面側の開口が露見してしまう。組立式の収納棚などにおいて、棚板を設置するためのダボを挿入するダボ穴が側板の板厚を貫通して形成される場合に、側板の側面に開口するダボ穴についても同様の問題が生ずる。このような場合に、開口を塞ぐシールを被着することも行われているが、剥がれやすく、長期に亘って目隠し効果を持続させることが困難であった。 Storage doors are formed with handle holes to accommodate handles for opening and closing, but due to the door thickness and ease of processing, the handle hole is often formed to penetrate the door thickness, and the handle is provided in the opening on the front side. In this case, if the handle hole is left open on the back side of the door, the opening on the back side of the handle hole will be exposed when the door is opened. In the case of a collapsible storage shelf, when dowel holes for inserting dowels to install shelves are formed to penetrate the thickness of the side panel, the same problem occurs with the dowel holes that open on the side of the side panel. In such cases, a sticker is applied to cover the opening, but this is prone to peeling off, making it difficult to maintain the concealing effect over the long term.
本出願人は、従来から、非特許文献１に示す扉裏面用目隠しキャップを提供している。この目隠しキャップ１０は、図１４に示すように、収納扉１の表裏に貫通する取手穴２の穴径Ｒと略同一またはそれより若干小さい径Ｒ１を有する基部１１と、基部１１の一端側に設けられて取手穴径Ｒより十分に大きい径Ｒ２を有するフランジ部１２と、基部１１の他端側に設けられて基部１１から離れるにつれてハの字状に拡開した形状を有して対向する一対の脚部１３，１３とからなるものとして、合成樹脂から一体形成されている。一対の脚部１３，１３は、常態においては、それらの下端部が取手穴径Ｒより十分に大きい開き寸法Ｗ１を有するように形成されているが、外力が作用することにより少なくとも取手穴径Ｒと略同一になるまで閉じる方向に変形可能である。脚部１３，１３の外面には凹凸状や鋸歯状などの係止部１４，１４が形成されている。 The applicant has been providing a cover cap for the back of a door as shown in Non-Patent Document 1. As shown in FIG. 14, this cover cap 10 is integrally formed from synthetic resin as comprising a base 11 having a diameter R1 that is approximately the same as or slightly smaller than the hole diameter R of the handle hole 2 that penetrates the front and back of the storage door 1, a flange portion 12 provided on one end of the base 11 and having a diameter R2 sufficiently larger than the handle hole diameter R, and a pair of legs 13, 13 provided on the other end of the base 11 and facing each other and having a shape that widens in a V-shape as it moves away from the base 11. In a normal state, the pair of legs 13, 13 are formed so that their lower ends have an opening dimension W1 that is sufficiently larger than the handle hole diameter R, but can be deformed in a closing direction until it becomes at least approximately the same as the handle hole diameter R when an external force is applied. The outer surfaces of the legs 13, 13 are formed with engagement portions 14, 14 that are uneven or sawtooth-shaped.
この目隠しキャップ１０の脚部１３，１３を取手穴径Ｒより略同一またはそれより小さい開き幅まで閉じた状態にして、収納扉１の裏面１ａ側に開口する取手穴２に挿入し、フランジ部１２の裏面が収納扉１の裏面１ａに当接するまで押し込む（図１５）。これにより、図に示す状態で目隠しキャップ１０が装着され、取手穴２の開口を塞いで見栄えを良好に保つことができる。脚部１３，１３は元の開いた状態（図１４）に弾性復帰しようとするので、それら
の外面に形成した係止部１４，１４が取手穴２の内面２ａに係止して、目隠しキャップ１０の抜け落ちを防止する。
The legs 13, 13 of this hiding cap 10 are closed to an opening width approximately equal to or smaller than the handle hole diameter R, and inserted into the handle hole 2 opening on the rear surface 1a side of the storage door 1, and pushed in until the rear surface of the flange portion 12 abuts against the rear surface 1a of the storage door 1 (Fig. 15) . This allows the hiding cap 10 to be attached in the state shown in the figure, closing the opening of the handle hole 2 and maintaining a good appearance. The legs 13, 13 elastically attempt to return to their original open state ( Fig. 14 ), so the locking portions 14, 14 formed on their outer surfaces lock onto the inner surface 2a of the handle hole 2, preventing the hiding cap 10 from falling off.
この目隠しキャップ１０は概ね良好に使用することができるものであったが、高密度ポリエチレン（ＪＩＳ Ｋ ６９２２－１，２では密度０．９４２ｇ／ｃｍ３以上）のような硬質の合成樹脂で形成すると、弾性変形の許容範囲が小さく、閉じた状態にして取手穴２に挿入することが困難になると共に、常態においてハの字状に拡開した脚部１３，１３が閉じた状態で取手穴２に装着されたときに、取手穴内面２ａに対して大きな押圧力が作用することによって脚部１３，１３の根本に掛かる応力が大きくなり、長期に亘って使用したときに、合成樹脂の経年劣化によって脚部１３，１３が破損し、取手穴２から脱落するという問題があった。反対に、低密度ポリエチレン（ＪＩＳ Ｋ ６９２２－１，２では密度０．９１～０．９３ｇ／ｃｍ３）のような軟質の合成樹脂で形成すると、脚部１３，１３の取手穴内面２ａに対する圧接力が小さくなり、目隠しキャップ１０が脱落しやすくなる。 This cover cap 10 was generally able to be used well, however, when it is formed from a hard synthetic resin such as high density polyethylene (density 0.942 g/cm3 or more according to JIS K 6922-1, 2 ), the tolerance for elastic deformation is small, making it difficult to insert it into the handle hole 2 in the closed state, and when the legs 13, 13, which are normally spread out in a V-shape, are attached to the handle hole 2 in the closed state, a large pressing force acts on the inner surface 2a of the handle hole, causing large stresses to be applied to the bases of the legs 13, 13, and when used over a long period of time, deterioration of the synthetic resin over time causes the legs 13, 13 to break and fall off from the handle hole 2. Conversely, if it is made of a soft synthetic resin such as low density polyethylene (density 0.91 to 0.93 g/cm 3 according to JIS K 6922-1 and 2), the pressure of the legs 13 against the handle hole inner surface 2a will be small, making the cover cap 10 more likely to fall off.
したがって、本発明が解決しようとする課題は、長期に亘って使用しても抜け落ちしにくい、目隠しキャップなどとして好適に用いられる挿入部材を提供することである。 Therefore, the problem that this invention aims to solve is to provide an insert member that is unlikely to fall off even after long-term use and is suitable for use as a blind cap, etc.
この課題を解決するため、本願の請求項１に係る発明は、被着体の面に開口する穴に挿入される挿入部材であって、穴に挿入可能な基部と、基部の一端に設けられる穴に挿入不能なフランジ部と、基部の他端側に設けられた先端が自由端である挿入片とを有してなり、挿入片は常態では基部から先端に向けて開き角度θ＝３５～４０度で開いていて穴に挿入不能であるがこれを閉じることにより穴に挿入および収容可能となる弾性材料から形成され、穴に収容されたときに常態に弾性復帰して開いた状態となることにより穴から抜けないように構成されており、挿入片の内面に、穴に収容された状態の挿入片に圧接する突起が設けられることを特徴とする。 In order to solve this problem, the invention of claim 1 of the present application is an insertion member to be inserted into a hole opening on the surface of an adherend, comprising a base that can be inserted into the hole, a flange portion that cannot be inserted into the hole and is provided at one end of the base, and an insertion piece whose tip is a free end and is provided on the other end of the base, the insertion piece being formed from an elastic material that, in its normal state , opens from the base to the tip at an opening angle θ = 35 to 40 degrees and cannot be inserted into the hole, but can be inserted and accommodated in the hole by closing this, and is configured so that when it is accommodated in the hole, it elastically returns to its normal open state and does not fall out of the hole, and is characterized in that a protrusion is provided on the inner surface of the insertion piece that presses against the insertion piece when it is accommodated in the hole.
本願の請求項２に係る発明は、請求項１記載の挿入部材において、突起が、挿入片の内面の長手方向略中央に設けられることを特徴とする。 The invention according to claim 2 of the present application is characterized in that in the insert member according to claim 1, the protrusion is provided at approximately the center in the longitudinal direction of the inner surface of the insert piece.
本願の請求項３に係る発明は、請求項１または２記載の挿入部材において、突起が、挿入片の幅方向に対向して設けられる一対の突起であることを特徴とする。 The invention according to claim 3 of the present application is characterized in that in the insert member according to claim 1 or 2, the protrusions are a pair of protrusions arranged opposite each other in the width direction of the insert piece.
本願の請求項４に係る発明は、請求項１ないし３のいずれか記載の挿入部材において、突起が、挿入片が常態にあるときには突起同士または突起と挿入片が当接せずそれらの間に隙間を残すように設けられることを特徴とする。 The invention according to claim 4 of the present application is characterized in that in the insert member according to any one of claims 1 to 3, the protrusions are arranged so that when the insert piece is in its normal state, the protrusions or the protrusions and the insert piece do not come into contact with each other, leaving a gap between them.
請求項１に係る発明によれば、穴に収容された状態の挿入片に圧接する突起が設けられるので、挿入片を穴の内面に押し付ける力が増大し、挿入部材の脱落を効果的に防止することができる。 According to the invention of claim 1, a protrusion is provided that presses the insert piece against the inner surface of the hole when it is housed in the hole, increasing the force pressing the insert piece against the inner surface of the hole and effectively preventing the insert member from falling out.
請求項２に係る発明によれば、突起が挿入片の内面の長手方向略中央に設けられるので、挿入片を閉じて穴に挿入する作業を容易に行うことができる。突起が挿入片の内面の先端寄りに位置していると、穴への挿入時に挿入片が穴より大きく開いてしまい、反対に突起が挿入片の内面の根本寄りに位置していると挿入片を穴より小さく閉じることが困難になり、いずれも穴にスムーズに挿入することができなくなる。 According to the invention of claim 2, the protrusion is provided at approximately the center of the longitudinal direction of the inner surface of the insertion piece, so that the insertion piece can be easily closed and inserted into the hole. If the protrusion is located toward the tip of the inner surface of the insertion piece, the insertion piece will open larger than the hole when inserted into the hole, and conversely, if the protrusion is located toward the base of the inner surface of the insertion piece, it will be difficult to close the insertion piece smaller than the hole, and in either case, it will be impossible to insert the insertion piece smoothly into the hole.
請求項３に係る発明によれば、挿入片の幅方向に対向して一対の突起が設けられるので、挿入片を閉じて穴に挿入するときに、突起同士が圧接して挿入片を安定させるので、穴への挿入が容易になる。また、穴に収容された状態の挿入片に対して対向する地点で均等に外方に向けて押圧力を与えるので、挿入部材の脱落を防止する効果がより大きくなる。 According to the invention of claim 3, a pair of protrusions are provided facing each other in the width direction of the insertion piece, so that when the insertion piece is closed and inserted into the hole, the protrusions come into pressure contact with each other to stabilize the insertion piece, making it easier to insert into the hole. In addition, a pressing force is evenly applied outward at the opposing points to the insertion piece when it is housed in the hole, which further increases the effect of preventing the insertion member from falling out.
請求項４に係る発明によれば、穴に挿入するために挿入片を閉じようとするときに、その少なくとも初期の段階では突起同士または突起と挿入片とが離れているので、穴へのスムーズな挿入を妨げない。 According to the invention of claim 4, when the insertion piece is closed to insert it into the hole, the protrusions or the protrusion and the insertion piece are separated at least in the initial stage, so smooth insertion into the hole is not hindered.
本発明について以下に実施例を挙げて詳細に説明する。 The present invention will be described in detail below with reference to examples.
図１～図３は本発明の一実施形態（実施例１）による目隠しキャップ１０Ａを示す。この目隠しキャップ１０Ａは、既述した従来技術による目隠しキャップ１０（図１４）と基本的に同様の構成を有しており、すなわち、収納扉１の表裏に貫通する取手穴２の穴径Ｒと略同一またはそれより若干小さい外径Ｒ１を有する基部１１と、基部１１の一端側に設けられて取手穴径Ｒより十分に大きい外径Ｒ２を有するフランジ部１２と、基部１１の他端側に設けられて基部１１から離れるにつれてハの字状に拡開した形状を有して対向する一対の脚部１３，１３とからなるものとして、低密度ポリエチレン（ＪＩＳ Ｋ ６９２２－１，２では密度０．９１～０．９３ｇ／ｃｍ３）で一体形成されている。一対の脚部１３，１３は、常態においては、それらの下端部が取手穴径Ｒより十分に大きい開き幅Ｗ１を有するように形成されているが、外力が作用することにより少なくとも取手穴径Ｒと略同一になるまで閉じる方向に変形可能である。脚部１３，１３の外面には凹凸状や鋸歯状などの係止部１４，１４が形成されている。なお、既述した従来技術による目隠しキャップ１０（図１４）と同一の構成要素には同一の符号が付されている。 1 to 3 show a cover cap 10A according to one embodiment of the present invention (Example 1). This cover cap 10A has a basically similar configuration to the cover cap 10 (FIG. 14) according to the conventional technology described above, that is, it is made of a base 11 having an outer diameter R1 that is approximately the same as or slightly smaller than the hole diameter R of a handle hole 2 that penetrates the front and back of a storage door 1, a flange portion 12 provided on one end of the base 11 and having an outer diameter R2 that is sufficiently larger than the handle hole diameter R, and a pair of opposing legs 13, 13 provided on the other end of the base 11 and having a V-shaped opening that widens as it moves away from the base 11, and is integrally formed from low-density polyethylene (density 0.91 to 0.93 g/cm 3 according to JIS K 6922-1 and 2). The pair of legs 13, 13 are formed so that their lower ends have an opening width W1 that is sufficiently larger than the handle hole diameter R in a normal state, but when an external force is applied, they can be deformed in the closing direction until they become at least approximately the same as the handle hole diameter R. Engagement portions 14, 14 having an uneven or sawtooth shape are formed on the outer surfaces of the legs 13, 13. The same components as those in the conventional concealing cap 10 (FIG. 14) described above are given the same reference numerals.
この基本構成に加えて、目隠しキャップ１０Ａにおいては、脚部１３，１３の長手方向略中央の内面に一対の断面略半円状の突起１５，１５が対向して形成されている。突起１５，１５は、脚部１３，１３が最大に拡開しているとき（図１）はそれらの間に間隔をおいて離れて位置しているが、目隠しキャップ１０Ａが取手穴２に挿入されて脚部１３，１３が取手穴径Ｒと同一に閉じられたとき（図４、下記）には突起１５，１５同士が互いに圧接して若干潰れた状態になるような位置関係に設けられる。 In addition to this basic configuration, in the concealing cap 10A, a pair of protrusions 15, 15 with a roughly semicircular cross section are formed facing each other on the inner surface of the legs 13, 13 at roughly the center in the longitudinal direction. The protrusions 15, 15 are positioned apart with a gap between them when the legs 13, 13 are fully opened (Fig. 1), but are positioned so that when the concealing cap 10A is inserted into the handle hole 2 and the legs 13, 13 are closed to the same diameter as the handle hole R (Fig. 4, below), the protrusions 15, 15 are pressed against each other and are slightly crushed.
上記構成の目隠しキャップ１０Ａの脚部１３，１３を取手穴径Ｒと略同一またはそれより小さい開き幅まで閉じた状態にして、収納扉１の裏面１ａ側に開口する取手穴２に挿入し、フランジ部１２の裏面が収納扉１の裏面１ａに当接するまで押し込む。これにより、図４に示す状態で目隠しキャップ１０Ａが装着され、取手穴２の開口を塞いで見栄えを良好に保つことができる。脚部１３，１３は元の開いた状態（図１）に弾性復帰しようとするので、それらの外面に形成した係止部１４，１４が取手穴２の内面２ａに係止して、目隠しキャップ１０Ａの抜け落ちを防止する。 The legs 13, 13 of the concealing cap 10A configured as above are closed to an opening width approximately equal to or smaller than the handle hole diameter R, inserted into the handle hole 2 opening on the rear surface 1a side of the storage door 1, and pushed in until the rear surface of the flange portion 12 abuts against the rear surface 1a of the storage door 1. This allows the concealing cap 10A to be attached in the state shown in Figure 4, blocking the opening of the handle hole 2 and maintaining a good appearance. The legs 13, 13 elastically attempt to return to their original open state (Figure 1), so the locking portions 14, 14 formed on their outer surfaces lock into the inner surface 2a of the handle hole 2, preventing the concealing cap 10A from falling off.
さらに、脚部１３，１３の内面に突起１５，１５を設けた目隠しキャップ１０Ａによれば、図４の装着状態において、突起１５，１５同士が互いに圧接しているので、その反力によって脚部１３，１３を取手穴内面２ａに対してより強い力で押し付ける。したがって、低密度ポリエチレンのような軟質合成樹脂で目隠しキャップ１０Ａを形成した場合であっても、目隠しキャップ１０Ａの抜け落ちを確実に防止することができ、且つ、高密度ポリエチレンのような硬質合成樹脂で目隠しキャップ１０を形成した場合のように、長期使用による経年劣化で脚部１３，１３が破損して脱落しやすくなるという問題も生じない。また、低密度ポリエチレンは弾性変形しやすく、脚部１３，１３を両側から挟むことにより容易に閉じることができるので、取手穴２への挿入が容易である。 Furthermore, according to the concealing cap 10A having the protrusions 15, 15 on the inner surface of the legs 13, 13, in the attached state shown in FIG. 4, the protrusions 15, 15 are pressed against each other, and the reaction force presses the legs 13, 13 against the handle hole inner surface 2a with a stronger force. Therefore, even if the concealing cap 10A is made of a soft synthetic resin such as low-density polyethylene, it is possible to reliably prevent the concealing cap 10A from falling off, and there is no problem that the legs 13, 13 are damaged and easily fall off due to deterioration over time, as occurs when the concealing cap 10 is made of a hard synthetic resin such as high-density polyethylene. In addition, low-density polyethylene is easily elastically deformed, and the legs 13, 13 can be easily closed by pinching them from both sides, making them easy to insert into the handle hole 2.
突起１５，１５は、既述したように、脚部１３，１３が最大拡開時（図１）には互いに離れているので、この状態よりさらに脚部１３，１３を拡開させようとする力を与えることがない。また、脚部１３，１３の内面の長手方向略中央に位置しているので取手穴２への挿入が容易である。図１２に示す変形例の目隠しキャップ１０Ａ’のように、突起１５，１５が脚部１３，１３の内面の先端寄りに位置していると、取手穴２への挿入時に脚部１３，１３が開いてしまい、また、図１３に示す目隠しキャップ１０Ａ”のように、突起１５，１５が脚部１３，１３の内面の根本寄りに位置していると閉じにくくなり、いずれも取手穴２にスムーズに挿入することができなくなる。突起１５，１５は、脚部１３，１３の先端から取手穴２に挿入する初期段階においては互いに当接せずに離れており、あるいはわずかな圧接力のみで当接しており、その後取手穴２の奥深くまで挿入していくにつれて徐々に強く圧接するように、その大きさおよび位置を決定する。 As mentioned above, the protrusions 15, 15 are separated from each other when the legs 13, 13 are fully opened (Figure 1), so they do not apply any force that would cause the legs 13, 13 to open further than this state. In addition, the protrusions 15, 15 are located approximately in the center of the inner surface of the legs 13, 13 in the longitudinal direction, making them easy to insert into the handle hole 2. If the protrusions 15, 15 are located near the tips of the inner surface of the legs 13, 13, as in the modified cover cap 10A' shown in Figure 12, the legs 13, 13 will open when inserted into the handle hole 2, and if the protrusions 15, 15 are located near the base of the inner surface of the legs 13, 13, as in the cover cap 10A'' shown in Figure 13, it will be difficult to close, and in either case it will not be possible to insert smoothly into the handle hole 2. The size and position of the protrusions 15, 15 are determined so that in the initial stage of inserting the tips of the legs 13, 13 into the handle hole 2, they are separated from each other and do not abut, or abut with only a slight pressure, and then they gradually press against each other more strongly as they are inserted deeper into the handle hole 2.
この目隠しキャップ１０Ａのように、各脚部１３，１３にそれぞれ突起１５，１５が設けられる場合は、突起１５，１５の高さ寸法を脚部１３，１３の厚さ寸法より小さくすることが好ましい。脚部１３，１３の厚さが突起１５，１５の高さより小さいと、脚部１３，１３が変形しやすくなり、取手穴２に収容された挿入片１３，１３を突起１５，１５が取手穴内面２ａに押圧する力に対して反発する力が弱くなり、目隠しキャップ１０Ａが脱落しやすくなる。 When protrusions 15, 15 are provided on each leg 13, 13, as in this concealing cap 10A, it is preferable to make the height dimension of the protrusions 15, 15 smaller than the thickness dimension of the leg 13, 13. If the thickness of the leg 13, 13 is smaller than the height of the protrusions 15, 15, the leg 13, 13 becomes more easily deformed, and the force of the protrusions 15, 15 pressing the insertion piece 13, 13 housed in the handle hole 2 against the inner surface 2a of the handle hole becomes weaker, making the concealing cap 10A more likely to fall off.
一対の対向する脚部１３，１３の開き角度θは任意であるが、一般に３５～４０度とすることが好ましい。この開き角度θが３５度未満であると、脚部１３，１３が取手穴２に挿入された状態（図２）における取手穴内面２ａへの押圧力が弱くなって目隠しキャップ１０Ａが脱落しやすくなる。開き角度θが４０度を超えると、目隠しキャップ１０Ａの材質にもよるが、脚部１３，１３を取手穴径Ｒより小さくなるまで閉じることが一般に困難になり、取手穴２に挿入しにくくなる。 The opening angle θ of the pair of opposing legs 13, 13 can be any angle, but is generally preferably 35 to 40 degrees. If the opening angle θ is less than 35 degrees, the pressing force on the inner surface 2a of the handle hole 2 when the legs 13, 13 are inserted into the handle hole 2 (Figure 2) will be weak, making the concealing cap 10A more likely to fall off. If the opening angle θ exceeds 40 degrees, it will generally be difficult to close the legs 13, 13 until they are smaller than the handle hole diameter R, making it difficult to insert them into the handle hole 2, although this will depend on the material of the concealing cap 10A.
図５は本発明の他実施形態（実施例２）による目隠しキャップ１０Ｂを示す。この目隠しキャップ１０Ｂは、既述した実施例１の目隠しキャップ１０Ａ（図１～図３）とほぼ同様の構成を有するが、一対の突起１５，１５が断面矩形状に形成されている点で異なっている。この目隠しキャップ１０Ｂの用法や作用は実施例１の目隠しキャップ１０Ａと同様であるので、説明を割愛する。 Figure 5 shows a concealing cap 10B according to another embodiment (Example 2) of the present invention. This concealing cap 10B has a configuration similar to that of the concealing cap 10A of Example 1 (Figures 1 to 3) described above, but differs in that a pair of protrusions 15, 15 are formed with a rectangular cross section. The usage and action of this concealing cap 10B are similar to those of the concealing cap 10A of Example 1, so a description thereof will be omitted.
図６は本発明の他実施形態（実施例３）による目隠しキャップ１０Ｃを示す。この目隠しキャップ１０Ｃは、既述した実施例１の目隠しキャップ１０Ａ（図１～図３）とほぼ同様の構成を有するが、一方の突起１５ａが断面略半円状に形成され、他方の突起１５ｂが断面略半円状の突起１５ａを篏合可能な凹面を有する断面形状に形成されている点で異なっている。この目隠しキャップ１０Ｃの用法や作用は実施例１の目隠しキャップ１０Ａと同様であるので、説明を割愛する。なお、この目隠しキャップ１０Ｃに示されるように、脚部１３，１３の内面に設けられる突起１５，１５は必ずしも同一の大きさ・形状を有するものでなくても良く、異なる大きさや形状に形成しても良い。 Figure 6 shows a concealing cap 10C according to another embodiment (Example 3) of the present invention. This concealing cap 10C has a configuration similar to that of the concealing cap 10A of Example 1 described above (Figures 1 to 3), but differs in that one protrusion 15a is formed in a substantially semicircular cross section, and the other protrusion 15b is formed in a cross-sectional shape with a concave surface that can engage with the substantially semicircular cross-sectional protrusion 15a. The usage and action of this concealing cap 10C are similar to those of the concealing cap 10A of Example 1, so a description thereof will be omitted. Note that, as shown in this concealing cap 10C, the protrusions 15, 15 provided on the inner surface of the legs 13, 13 do not necessarily have to have the same size and shape, and may be formed in different sizes and shapes.
図７は本発明の他実施形態（実施例４）による目隠しキャップ１０Ｄを示す。この目隠しキャップ１０Ｄは、既述した実施例１の目隠しキャップ１０Ａ（図１～図３）とほぼ同様の構成を有するが、一方の脚部１３のみに、その内面の長手方向略中央に突起１５が形成されている点で異なっている。この目隠しキャップ１０Ｄの用法や作用は実施例１の目隠しキャップ１０Ａと同様であるので、説明を割愛する。なお、この目隠しキャップ１０Ｄに示されるように、一方の脚部１３のみに単一の突起１５を設ける場合は、両方の脚部１３，１３に各々設けられる場合の突起１５と比べてやや大きく形成すると良い。 Figure 7 shows a concealing cap 10D according to another embodiment (Example 4) of the present invention. This concealing cap 10D has a configuration similar to that of the concealing cap 10A of Example 1 (Figures 1 to 3) described above, but differs in that a protrusion 15 is formed on only one of the legs 13, approximately in the center of the longitudinal direction of the inner surface. The usage and action of this concealing cap 10D are similar to those of the concealing cap 10A of Example 1, so a description will be omitted. Note that, as shown in this concealing cap 10D, when a single protrusion 15 is provided on only one of the legs 13, it is preferable to form the protrusion 15 slightly larger than when it is provided on both legs 13, 13.
図８は本発明の他実施形態（実施例５）による目隠しキャップ１０Ｅを示す。実施例１～４の目隠しキャップ１０Ａ～１０Ｄにおいては、取手穴２に挿入される挿入片として、ハの字状に拡開する一対の脚部１３，１３を１８０度間隔で対向させて形成しているが、これに代えて、図８に示すように、３つの脚部１３，１３，１３を１２０度間隔で形成し、これら脚部１３の内面に各々突起１５を設けても良い。この目隠しキャップ１０Ｅの用法や作用は実施例１の目隠しキャップ１０Ａと同様であるので、説明を割愛する。図示省略するが、４つの脚部を９０度間隔（またはより多数の脚部を等間隔）で形成し、各脚部１３の内面に突起１５を設けても良く、その用法や作用も同様である。 Figure 8 shows a concealing cap 10E according to another embodiment (Example 5) of the present invention. In the concealing caps 10A to 10D of Examples 1 to 4, a pair of legs 13, 13 that open in a V-shape are formed facing each other at 180 degree intervals as insertion pieces to be inserted into the handle hole 2. Alternatively, as shown in Figure 8, three legs 13, 13, 13 may be formed at 120 degree intervals, and each of these legs 13 may have a protrusion 15 on its inner surface. The usage and function of this concealing cap 10E is similar to that of the concealing cap 10A of Example 1, so a description thereof will be omitted. Although not shown, four legs may be formed at 90 degree intervals (or a larger number of legs may be equally spaced), and protrusions 15 may be provided on the inner surface of each leg 13, and the usage and function are similar.
図９は本発明の他実施形態（実施例６）による目隠しキャップ１０Ｆを示す。既述した実施例１の目隠しキャップ１０Ａ（図１）においては一対の脚部１５，１５を対向して形成して挿入片としているのに対し、この目隠しキャップ１０Ｆには断面略Ｏ字状の挿入片１６が形成されている点で異なっている。この断面Ｏ字状の挿入片１６は常態において取手穴径Ｒより大きい幅Ｗ２を有するが、取手穴２に挿入されたとき（図１０）にはその内部の空洞が収縮して取手穴径Ｒと略同一の幅となり、外面に形成した係止部１４，１４が取手穴内面２ａに圧接すると共に、挿入片１６の内面の長手方向略中央に対向して設けた一対の突起１５，１５同士が圧接して若干潰れた状態となって、実施例１の目隠しキャップ１０Ａと同様の作用を発揮する。 Figure 9 shows a concealing cap 10F according to another embodiment (Example 6) of the present invention. The concealing cap 10A (Figure 1) of Example 1 described above has a pair of legs 15, 15 formed opposite each other to form an insert piece, whereas this concealing cap 10F is different in that an insert piece 16 with a substantially O-shaped cross section is formed. This O-shaped cross section insert piece 16 has a width W2 larger than the handle hole diameter R in the normal state, but when inserted into the handle hole 2 (Figure 10), the internal cavity contracts to a width substantially equal to the handle hole diameter R, and the locking parts 14, 14 formed on the outer surface are pressed against the handle hole inner surface 2a, and a pair of protrusions 15, 15 provided opposite each other at approximately the center of the longitudinal direction of the inner surface of the insert piece 16 are pressed against each other to become slightly crushed, thereby exerting the same effect as the concealing cap 10A of Example 1.
既述した実施例１～６は、目隠しキャップ１０Ａ～１０Ｆを取手穴２の目隠しに用いるものとして説明したが、本発明は、被着体の面に開口する穴を利用してカバーなどの部材を取り付けるための部材としても使用可能である。図１１は、実施例１の目隠しキャップ１０Ａと同様の構成を有する部材１０Ａを用いて、被着体３の面３ａに開口する既設の穴４を利用してカバー５を取り付けた使用状態を示している。このような用法においても、実施例１の目隠しキャップ１０Ａについて図４を参照して既述したように、脚部１３，１３を閉じた状態にしてカバー５の穴（符号なし）から被着体３の穴４に挿入して、フランジ部１２がカバー５を介して被着体３に密接するまで押し込んで装着することにより、脚部１３，１３の外面に形成した係止部１４，１４が穴４の内面４ａに圧接すると共に、突起１５，１５同士が互いに圧接するので、部材１０Ａの抜け落ちが確実に防止され、したがってカバー５の取付状態を長期に亘って強固に保持することができる。 In the above-mentioned Examples 1 to 6, the cover caps 10A to 10F were described as being used to cover the handle hole 2, but the present invention can also be used as a member for attaching a member such as a cover by utilizing a hole that opens on the surface of the adherend. Figure 11 shows the use state in which a member 10A having a configuration similar to that of the cover cap 10A of Example 1 is used to attach a cover 5 by utilizing an existing hole 4 that opens on the surface 3a of the adherend 3. Even in this type of usage, as already described with reference to FIG. 4 for the concealing cap 10A of Example 1, the legs 13, 13 are closed and inserted through the hole (not numbered) in the cover 5 into the hole 4 in the adherend 3, and the flange portion 12 is pressed against the adherend 3 through the cover 5 until it is in close contact with the adherend 3. This causes the locking portions 14, 14 formed on the outer surfaces of the legs 13, 13 to press against the inner surface 4a of the hole 4, and the protrusions 15, 15 to press against each other, reliably preventing the member 10A from falling off, and therefore the cover 5 can be firmly maintained in its attached state for a long period of time.
本発明について実施例を挙げて説明したが、本発明は特許請求の範囲に記載された発明の範囲内において多種多様に変形ないし変更して実施可能である。本発明は、実施例において既述したように収納扉の裏面に開口する取手穴を目隠しするためだけでなく、あらゆる被着体のいずれかの面に開口する穴を目隠しするために用いることができ、さらには、図１１を参照して既述したようにカバーなどの他部材を被着体に取り付けるための部材としても使用可能である。本発明の挿入部材が装着される穴は、被着体の両面に開口する貫通穴であっても、被着体の片面のみに開口する穴（図１１の穴４参照）であっても良い。 The present invention has been described with reference to examples, but the present invention can be practiced with a wide variety of modifications and alterations within the scope of the invention described in the claims. The present invention can be used not only to conceal handle holes opening on the back surface of a storage door as described in the examples, but also to conceal holes opening on any surface of any adherend, and further, as described with reference to Figure 11, it can be used as a member for attaching other members such as a cover to an adherend. The hole into which the insertion member of the present invention is attached may be a through hole opening on both surfaces of the adherend, or a hole opening on only one surface of the adherend (see hole 4 in Figure 11).
