JP 2001-208276 A Patent No. 3988000

しかし、上記特許文献１に記載の発明においては、当接片と板状体とは蓋板部の偏心位置に設けられているため、壁孔の中心位置に対して蓋盤部の中心位置がずれた状態で装着されてしまうことがある。このとき、図９の符号１０５に示すように壁孔の開口径が大きい場合には壁孔１０５の開口部が蓋盤部の外にはみ出してしまい、建物の美観を損ねたり、埃等の侵入で室内が汚れたりするという問題が生ずる。それゆえに、上記特許文献１に記載の発明は適切な態様で壁孔に装着することが難しいという問題が生ずる。さらに、上記特許文献１に記載の発明においては、当接片と板状体とが壁孔内部に圧接されて装着されるが、当接片は形状不変で板状体が弾性変形する構成であるため、壁孔の開口径が小さい場合には板状体の撓み量が大きくなってしまう。このため、繰り返しの使用や長年の使用による板状体の劣化や破損が起こりやすくなるという問題が生ずる。   However, in the invention described in Patent Document 1, since the contact piece and the plate-like body are provided at the eccentric position of the cover plate portion, the center position of the cover plate portion is set to the center position of the wall hole. It may be worn out of position. At this time, as shown by reference numeral 105 in FIG. 9, when the opening diameter of the wall hole is large, the opening portion of the wall hole 105 protrudes outside the cover board portion, which impairs the aesthetic appearance of the building or intrusions of dust or the like. This causes the problem that the room gets dirty. Therefore, the invention described in Patent Document 1 has a problem that it is difficult to mount the wall hole in an appropriate manner. Furthermore, in the invention described in Patent Document 1, the contact piece and the plate-like body are mounted in pressure contact with each other in the wall hole. However, the contact piece has a configuration in which the plate-like body is elastically deformed without changing its shape. Therefore, when the opening diameter of the wall hole is small, the amount of bending of the plate-like body becomes large. For this reason, there arises a problem that the plate-like body is likely to be deteriorated or damaged due to repeated use or long-term use.

また、上記特許文献２に記載の発明においては、板状体に摺接部材や係止片を設けることで構造が複雑化してしまい、コスト高になってしまうという問題や、壁孔に壁孔閉塞用蓋を取り付ける際に係止片を被係止部に係止させねばならず、作業が複雑化してしまうという問題がある。   Further, in the invention described in the above-mentioned Patent Document 2, the structure becomes complicated by providing a sliding contact member or a locking piece on the plate-like body, and the cost becomes high. When attaching the closure lid, the locking piece must be locked to the locked portion, and there is a problem that the operation becomes complicated.

本発明はこのような問題に鑑みてなされたものであり、簡易な構成で低コストで製造できて、壁孔の大きさに拘わらず壁孔を隙間なく塞ぐことができて、繰り返しの使用や長年の使用によっても劣化や破損が起こりにくく、簡易に壁孔に装着できる壁孔閉塞用蓋を提供することを課題としている。   The present invention has been made in view of such problems, and can be manufactured at a low cost with a simple configuration, and can close the wall hole without any gap regardless of the size of the wall hole. It is an object of the present invention to provide a wall hole closing lid that is less likely to deteriorate or break down even after many years of use and can be easily attached to a wall hole.

請求項４に記載の発明は、請求項１乃至３の何れか一つに記載の構成に加え、前記蓋盤部の板面の外周部近傍には、前記蓋盤部の一部を切除するための直線状の切取溝が陥没形成されていることを特徴とする。   According to a fourth aspect of the present invention, in addition to the configuration according to any one of the first to third aspects, a part of the lid part is cut off in the vicinity of the outer peripheral part of the plate surface of the lid part. For this purpose, a linear cutout groove is recessed.

請求項１に記載の発明によれば、止着手段は、蓋盤部の中央部側に立設された固定部と、弾性変形可能な板状体からなり、一端部が固定部に接合すると共に他端部側は蓋盤部の外周部方向に向けて延長され、壁孔の内部に圧接される弾性片部とを有する止着片部を一対備えたことにより、壁孔に止着手段を挿入したときに一対の弾性片部がそれぞれ固定部方向に弾性変形し、壁孔の内周部に圧接されることになる。このとき、一対の弾性片部がそれぞれ弾性変形することになるため、それぞれの弾性片部の撓み量は小さくて済み、撓みによる弾性片部の負荷が過大になることを防止できる。また、それぞれの止着片部は蓋盤部の中心位置を基準として略対称位置に配設され、壁孔に装着される前の状態において壁孔の中心と蓋盤部の中心位置とを一致させた際に、それぞれの弾性片部の先端部が壁孔の開口部の周縁部よりも外方に突出されると共に、壁孔に装着された状態において、それぞれの弾性片部の先端部が蓋盤部の中心位置方向に弾性変形して壁孔の内部に圧接されて止着されるように形成されたことにより、壁孔の中心位置と蓋盤部の中心位置を略一致させた状態で壁孔閉塞用蓋を壁孔に取り付けることができる。そのため、壁孔の開口径が大きい場合でも、壁孔の開口部の一部が蓋盤部の外にはみ出してしまう事態を簡単に防止できる。さらに、弾性片には押圧部材や係止片のように複雑な構成が設けられていないため、壁孔閉塞用蓋を製造する際に複雑な構成の金型を用いる必要がなく、製造コストの高騰を抑止できる。これにより、簡易な構成で低コストで製造できて、壁孔の大きさに拘わらず壁孔を隙間なく塞ぐことができて、繰り返しの使用や長年の使用によっても劣化や破損が起こりにくく、簡易に壁孔に取り付けることができる壁孔閉塞用蓋を提供することができる。   According to the first aspect of the present invention, the fastening means is composed of a fixing portion erected on the center side of the lid portion and a plate body that can be elastically deformed, and one end portion is joined to the fixing portion. In addition, the other end portion is extended toward the outer peripheral portion of the cover plate portion and includes a pair of fastening pieces having an elastic piece pressed against the inside of the wall hole, so that the fastening means is attached to the wall hole. When the is inserted, the pair of elastic pieces are elastically deformed in the direction of the fixed part, and are pressed against the inner peripheral part of the wall hole. At this time, since the pair of elastic pieces are elastically deformed, the amount of bending of each elastic piece can be small, and the load on the elastic pieces due to the bending can be prevented from becoming excessive. In addition, each fastening piece portion is disposed at a substantially symmetrical position with respect to the center position of the cover plate portion, and the center of the wall hole and the center position of the cover plate portion coincide with each other before being attached to the wall hole. When this is done, the tip of each elastic piece protrudes outward from the peripheral edge of the opening of the wall hole, and in the state of being attached to the wall hole, the tip of each elastic piece is A state in which the center position of the wall hole and the center position of the cover plate portion are substantially coincided with each other by being elastically deformed in the direction of the center position of the cover plate portion and being pressed and fixed inside the wall hole. The wall hole closing lid can be attached to the wall hole. Therefore, even when the opening diameter of the wall hole is large, it is possible to easily prevent a situation where a part of the opening portion of the wall hole protrudes outside the cover board portion. Further, since the elastic piece is not provided with a complicated configuration like a pressing member or a locking piece, it is not necessary to use a mold having a complicated configuration when manufacturing the wall hole closing lid, which reduces the manufacturing cost. Can prevent soaring. As a result, it can be manufactured at a low cost with a simple configuration, and the wall hole can be closed without any gap regardless of the size of the wall hole, and it is not easily deteriorated or damaged by repeated use or long-term use. A wall hole closing lid that can be attached to the wall hole can be provided.

請求項２に記載の発明によれば、一対の弾性片部は、それぞれの板面を略平行に対向させて配設されると共に、それぞれの先端部はそれぞれの基端部同士を結ぶ仮想線に対してそれぞれ反対方向に向けて延長されたことにより、壁孔に止着手段を嵌挿させて壁孔にそれぞれの弾性板部を圧着させたとき、蓋盤部の中心位置に対して略対称の位置から蓋盤部の中心位置方向に向けてそれぞれ略等しい弾性力を加えることができる。これにより、壁孔閉塞用蓋を壁孔に取り付けたときに、それぞれの弾性片部の弾性力のみによって、壁孔の中心位置と蓋盤部の中心位置を容易に略一致させることでき、壁孔の大きさに拘わらず確実に壁孔を隙間なく塞ぐことができて、一層簡易に壁孔に取り付けることができる壁孔閉塞用蓋を提供することができる。   According to the second aspect of the present invention, the pair of elastic pieces are disposed with their plate surfaces facing each other substantially in parallel, and each distal end portion is an imaginary line connecting the respective base end portions. When the fastening means is inserted into the wall hole and the respective elastic plate part is crimped to the wall hole, the center position of the lid part is substantially reduced. A substantially equal elastic force can be applied from the symmetrical position toward the center position of the lid part. As a result, when the wall hole closing lid is attached to the wall hole, the center position of the wall hole and the center position of the cover plate portion can be easily substantially matched by only the elastic force of each elastic piece portion. It is possible to provide a wall hole closing lid that can reliably close the wall hole without any gap regardless of the size of the hole and can be attached to the wall hole more easily.

請求項３に記載の発明によれば、蓋盤部の一部には凹部が形成され、凹部には、一対の壁孔閉塞用蓋を壁孔の一対の開口部にそれぞれ装着させた状態でそれぞれの壁孔閉塞用蓋同士を連結させるための連結部材が挿通される貫通孔が形成され、貫通孔を覆った状態で凹部に嵌合されるキャップ部材が設けられ、キャップ部材には取付片が延設されており、取付片の先端には鉤状の抜止部が形成され、凹部に形成された取付孔への挿入時には、抜止部が弾性変形することで抜止部を取付孔に挿入可能になり、取付孔への挿入完了後は抜止部が元の状態に復帰することで抜止部が係止されるように形成されたことにより、取付孔に抜止部を圧入することで抜止部を取付孔に挿入させ、取付孔を貫通した抜止部を係止させることができる。従って、キャップ部材の取付工程を抜止部の圧入のみで簡易に行うことができる。そして、抜止部を係止させたキャップ部材を凹部に嵌合させることで、連結部材や連結部材が貫通した貫通孔が外部に露出して美観を損なう事態を防止できる。   According to the invention described in claim 3, a recess is formed in a part of the lid part, and a pair of wall hole closing lids are respectively attached to the pair of openings of the wall hole in the recess. A through-hole through which a connecting member for connecting the respective wall-hole closing lids is inserted is formed, and a cap member fitted to the recess is provided in a state of covering the through-hole. A hook-shaped retaining portion is formed at the tip of the mounting piece, and the retaining portion can be inserted into the mounting hole by elastic deformation when inserted into the mounting hole formed in the recess. After the insertion into the mounting hole is completed, the retaining part is formed so that the retaining part is locked by returning to the original state, so that the retaining part is pressed into the mounting hole to press the retaining part. The retaining portion penetrating the mounting hole can be locked by being inserted into the mounting hole. Therefore, the attaching process of the cap member can be easily performed only by press-fitting the retaining portion. Then, by fitting the cap member locking the retaining portion into the recess, it is possible to prevent a situation in which the connecting member or the through-hole through which the connecting member has been exposed is exposed to the outside and the appearance is impaired.

請求項４に記載の発明によれば、蓋盤部の板面の外周部近傍には、蓋盤部の一部を切除するための直線状の切取溝が陥没形成されていることにより、蓋盤部の切取溝よりも外周部側を容易に切除することが可能になる。これにより、蓋盤部のうち壁孔を塞ぐために必要のない部分が生じた際に蓋盤部の一部を切除する作業を容易に行うことができて、壁孔閉塞用蓋を一層簡易に壁孔に取り付けることができる。   According to the fourth aspect of the present invention, a linear cut groove for cutting off a part of the lid part is formed in the vicinity of the outer peripheral part of the plate surface of the lid part. It is possible to easily cut the outer peripheral portion side than the cutout groove of the board portion. As a result, when a part of the lid part that is not necessary for closing the wall hole is generated, the part of the lid part can be easily removed, and the wall hole closing lid can be further simplified. Can be attached to the wall hole.

なお、この連結部材３５はポリプロピレン等の樹脂によって形成され、図４の（ｂ）、及び図６に示す通り、バンド部３６と、バンド部３６の基端側に設けられたストッパ部３８とを有する。バンド部３６は平棒状に形成され、一方面側（図７の上面側）には鋸歯状の係止溝３７が複数形成されている。ストッパ部３８は、ストッパ収容部４２に収容可能な大きさの略箱形に形成されている。ストッパ部３８の略中央部には貫通孔部３９が形成され、貫通孔部３９の内部には係止舌片４０が突設されている。   The connecting member 35 is formed of a resin such as polypropylene. As shown in FIG. 4B and FIG. 6, the connecting member 35 includes a band portion 36 and a stopper portion 38 provided on the base end side of the band portion 36. Have. The band portion 36 is formed in a flat bar shape, and a plurality of serrated locking grooves 37 are formed on one surface side (the upper surface side in FIG. 7). The stopper portion 38 is formed in a substantially box shape having a size that can be accommodated in the stopper accommodating portion 42. A through-hole portion 39 is formed at a substantially central portion of the stopper portion 38, and a locking tongue piece 40 projects from the inside of the through-hole portion 39.

また、図１の（ｂ）、図２の（ｂ）、図４の（ｂ）に示す通り、凹部２６には、貫通孔２７，２８，４３を覆った状態で凹部２６に嵌合されるキャップ部材３０が設けられている。   Further, as shown in FIGS. 1B, 2B, and 4B, the recess 26 is fitted into the recess 26 while covering the through holes 27, 28, and 43. A cap member 30 is provided.

図５に示す通り、キャップ部材３０は、蓋部３４、取付片３１、抜止部３２を有する。蓋部３４は有蓋円筒形に形成されており、表面側から見て、外周部は凹部２６の内周部に略等しい大きさに形成されている。取付片３１は平棒状に形成されており、蓋部３４の一側部から下方に向けて延設されている。取付片３１は板面方向の力に対して容易に弾性変形しうる厚さに形成されている。図５の（ｃ）に示す通り、抜止部３２は、取付片３１の先端において、先端が尖った鉤状に形成されている。抜止部３２は、取付片３１と同様の平棒状の部材が鋭角に折り返された形状に形成されている。これにより、抜止部３２が鋭角の角度方向Ｗに拡縮自在に形成されている。   As shown in FIG. 5, the cap member 30 includes a lid portion 34, an attachment piece 31, and a retaining portion 32.

Thereby, the retaining portion 32 is formed so as to be freely expandable and contractable in the acute angle direction W.

次に、この実施の形態の壁孔閉塞用蓋１０の作用について説明する。   Next, the operation of the wall hole closing lid 10 of this embodiment will be described.

この実施の形態の壁孔閉塞用蓋１０を用いた製品の製造工程について説明すると、本体部１１とキャップ部材３０とを製造したのち、本体部１１にキャップ部材３０を装着する。具体的には、蓋盤部１４の表面側から、凹部２６の取付孔２９にキャップ部材３０の抜止部３２を接触させ、この状態で取付片３１に取付孔２９方向への力を加えて、抜止部３２を取付孔２９に圧入する。圧入時に加わる力によって抜止部３２は弾性変形して角度方向Ｗに縮小し、これによって抜止部３２を取付孔２９に貫通させることが可能になり、抜止部３２が取付孔２９を貫通して挿入が完了した後は、抜止部３２が角度方向Ｗに拡開して元の状態に復帰することで抜止部３２が係止される。   The manufacturing process of the product using the wall hole closing lid 10 of this embodiment will be described. After the main body 11 and the cap member 30 are manufactured, the cap member 30 is attached to the main body 11. Specifically, from the surface side of the lid part 14, the retaining portion 32 of the cap member 30 is brought into contact with the attachment hole 29 of the recess 26, and in this state, a force in the direction of the attachment hole 29 is applied to the attachment piece 31. The retaining portion 32 is press-fitted into the mounting hole 29. The retaining portion 32 is elastically deformed by the force applied at the time of press-fitting and contracts in the angle direction W, so that the retaining portion 32 can be passed through the mounting hole 29, and the retaining portion 32 is inserted through the mounting hole 29. Is completed, the retaining portion 32 expands in the angular direction W and returns to its original state, so that the retaining portion 32 is locked.

次に、壁孔閉塞用蓋１０を２つ用意し、一方の壁孔閉塞用蓋１０の蓋盤部１４の表面側から、連結部材３５のバンド部３６の先端部を第三貫通孔４３に挿入し、さらにバンド部３６の基端部側まで第三貫通孔４３に挿通させて、ストッパ３８がストッパ収容部４２に収容された状態とする。これにより、バンド部３６が第三貫通孔４３に挟持された状態となり、ストッパ３８はストッパ収容部４２に収容された状態で固着される。   Next, two wall hole closing lids 10 are prepared, and the front end portion of the band portion 36 of the connecting member 35 is connected to the third through hole 43 from the surface side of the lid plate portion 14 of the one wall hole closing lid 10. Then, the stopper 38 is accommodated in the stopper accommodating portion 42 by being inserted through the third through hole 43 to the base end side of the band portion 36. As a result, the band portion 36 is sandwiched between the third through holes 43, and the stopper 38 is fixed in a state of being accommodated in the stopper accommodating portion 42.

そして、一方の壁孔閉塞用蓋１０に挿通されたバンド部３６を、蓋盤部１４の裏面側に突出した基端部近傍の任意の箇所で切断する。以上の工程により、図７，図８に示す、壁孔閉塞用蓋１０を用いた第一の部材（以下単に「第一の部材」と称する。）５１を完成させる。   Then, the band portion 36 inserted through the one wall hole closing lid 10 is cut at an arbitrary location near the base end portion protruding to the back surface side of the lid plate portion 14. The first member (hereinafter simply referred to as “first member”) 51 using the wall hole closing lid 10 shown in FIGS.

次に、他方の壁孔閉塞用蓋１０の蓋盤部１４の表面側から、連結部材３５のバンド部３６の先端部を第一貫通孔２７に挿入し、さらにバンド部３６の基端部側まで第一貫通孔２７に挿通させる。このとき、バンド部３６の係止溝３７が蓋盤部１４の上側（図４に示す上側）に向くように第一貫通孔２７に挿通させる。そして、他方の壁孔閉塞用蓋１０に挿通されたバンド部３６は切断しないでおく。以上の工程により、図７，図８に示す、壁孔閉塞用蓋１０を用いた第二の部材（以下単に「第二の部材」と称する。）５２を完成させる。   Next, the front end portion of the band portion 36 of the connecting member 35 is inserted into the first through hole 27 from the surface side of the cover plate portion 14 of the other wall hole closing lid 10, and further the base end portion side of the band portion 36 Until the first through hole 27 is inserted. At this time, the locking groove 37 of the band part 36 is inserted through the first through hole 27 so as to face the upper side (upper side shown in FIG. 4) of the cover board part 14. Then, the band portion 36 inserted through the other wall hole closing lid 10 is not cut. The second member (hereinafter simply referred to as “second member”) 52 using the wall hole closing lid 10 shown in FIGS. 7 and 8 is completed by the above steps.

この実施の形態の壁孔閉塞用蓋１０を用いた製品を壁孔１２に装着する際の作業工程について説明すると、まず、第一の部材５１と第二の部材５２とを一つずつ用意する。そして、作業者は、それぞれの壁孔閉塞用蓋１０において、キャップ部材３０の蓋部３４を凹部２６から離脱させて蓋部３４が開いた状態とする。   The working process when mounting the product using the wall hole closing lid 10 of this embodiment to the wall hole 12 will be described. First, the first member 51 and the second member 52 are prepared one by one. . Then, in each of the wall hole closing lids 10, the worker removes the lid portion 34 of the cap member 30 from the concave portion 26 and opens the lid portion 34.

次に、作業者は、第二の部材５２における、壁孔閉塞用蓋１０に挿通されたバンド部３６を壁孔１２の内部に挿入したのちに、図６に示すように、止着手段１５を壁孔１２の開口部１３側に向けた状態で開口部１３に対向させる。   Next, the operator inserts the band portion 36 inserted through the wall hole closing lid 10 in the second member 52 into the wall hole 12, and then, as shown in FIG. Is made to face the opening 13 in a state in which it faces the opening 13 side of the wall hole 12.

そして、図６に示すように、一方の弾性片部１９を壁孔１２の内部に挿入して仮想中心点１７方向に弾性変形させたのち、他方の弾性片部１９の摺接側縁部２４を開口部１３に当接させて、蓋盤部１４を作業者から見て時計回り（図６に示す矢印Ｒ方向）に回転させながら開口部１３方向への押圧力を加える。すると、他方の弾性片部１９が仮想中心点１７方向に弾性変形する。なお、弾性片部１９が弾性変形しても、固定部１８の形状は変化しない。   Then, as shown in FIG. 6, after one elastic piece 19 is inserted into the wall hole 12 and elastically deformed in the direction of the virtual center point 17, the sliding contact side edge 24 of the other elastic piece 19 is obtained. Is brought into contact with the opening 13 and a pressing force in the direction of the opening 13 is applied while rotating the lid 14 clockwise as viewed from the operator (in the direction of arrow R shown in FIG. 6). Then, the other elastic piece 19 is elastically deformed in the direction of the virtual center point 17. Even if the elastic piece 19 is elastically deformed, the shape of the fixing portion 18 does not change.

ここで、前述した通り、弾性片部１９は、基端部２１側から先端部２２側にかけて高さ方向大きさＨが縮小し、また、蓋盤部１４と反対側に略直線状に形成された摺接側縁部２４が、先端部２２側が蓋盤部１４に近接する方向に傾斜している。そのため、摺接側縁部２４を開口部１３に当接させた状態で、蓋盤部１４に開口部１３方向への押圧力を加えることで、摺接側縁部２４が開口部１３に摺接しながら弾性片部１９が蓋盤部１４の仮想中心点１７方向におのずと弾性変形してゆくことになる。   Here, as described above, the elastic piece portion 19 has a height direction size H that decreases from the base end portion 21 side to the tip end portion 22 side, and is formed in a substantially linear shape on the opposite side to the lid portion 14. The slidable contact side edge portion 24 is inclined in a direction in which the tip portion 22 side is close to the cover plate portion 14. For this reason, the sliding contact edge 24 is slid onto the opening 13 by applying a pressing force in the direction of the opening 13 to the lid 14 with the sliding contact edge 24 in contact with the opening 13. The elastic piece 19 is elastically deformed naturally in the direction of the imaginary center point 17 of the lid 14 while contacting.

そして、弾性片部１９の弾性変形により摺接側縁部２４の開口部１３との接触位置が弾性片部１９の先端部２２方向に移動してゆき、摺接側縁部２４の開口部１３との接触位置が他方の弾性片部１９の先端部２２まで移動すると、弾性片部１９全体が壁孔１２の内部に挿入されることになる。   Then, due to the elastic deformation of the elastic piece portion 19, the contact position of the sliding contact side edge portion 24 with the opening portion 13 moves toward the distal end portion 22 of the elastic piece portion 19, and the opening portion 13 of the sliding contact side edge portion 24. When the contact position moves to the tip 22 of the other elastic piece 19, the entire elastic piece 19 is inserted into the wall hole 12.

そして、更に蓋盤部１４に開口部１３方向への押圧力を加え、蓋盤部１４の板面が開口部１３に接触させると、図７及び図８に示す通り、第二の部材５２の壁孔閉塞用蓋１０の蓋盤部１４が開口部１３の全面を塞いだ状態となる。なお、図７及び図８においては、一対の壁孔閉塞用蓋１０，１０のうち図中左側に示されているのが第二の部材５２の壁孔閉塞用蓋１０に該当する。この状態において、一対の弾性片部１９，１９はそれぞれ壁孔１２の内部で弾性変形して壁孔１２の内部に圧接され、この圧接力によって壁孔閉塞用蓋１０は壁孔１２に止着される。なお、図７及び図８に示す第二の部材５２の壁孔閉塞用蓋１０は、図１乃至図４に示す上下方向の向きを維持した状態で壁孔１２に止着され、バンド部３６の係止溝３７が上側を向いた状態に配設されている。   Further, when a pressing force in the direction of the opening 13 is further applied to the lid 14, and the plate surface of the lid 14 is brought into contact with the opening 13, the second member 52 of the second member 52, as shown in FIGS. The lid 14 of the wall hole closing lid 10 is in a state of covering the entire surface of the opening 13. 7 and 8, the left side of the pair of wall hole closing lids 10, 10 corresponds to the wall hole closing lid 10 of the second member 52. In this state, each of the pair of elastic pieces 19, 19 is elastically deformed inside the wall hole 12 and pressed into the wall hole 12, and the wall hole closing lid 10 is fixed to the wall hole 12 by this pressure contact force. Is done. 7 and 8, the wall hole closing lid 10 of the second member 52 is fixed to the wall hole 12 while maintaining the vertical direction shown in FIGS. The locking groove 37 is arranged in a state of facing upward.

そして、作業者は壁孔１２に止着された第二の部材５２の壁板閉塞用蓋１０の蓋部３４を凹部２６に嵌合させて、蓋部３４を閉じる。これにより、蓋盤部１４の表面側から見て、連結部材３５や連結部材３５が貫通した各貫通孔２７，２８，４３は、蓋部３４によって隠された状態となる。   Then, the operator fits the lid portion 34 of the wall plate closing lid 10 of the second member 52 fixed to the wall hole 12 into the concave portion 26 and closes the lid portion 34. Thereby, when viewed from the front surface side of the lid part 14, the connection member 35 and the through holes 27, 28, and 43 through which the connection member 35 penetrates are hidden by the lid part 34.

次に、作業者は、第一の部材５１の壁孔閉塞用蓋１０を、第二の部材５２の壁孔閉塞用蓋１０と上下方向の向きが一致した状態（即ち、図７及び図８においては、図１乃至図４に示す上下方向の向きを維持した状態）で壁孔１２の開口部１３に近づける。そして、第二の部材５２のバンド部３６の先端部を、第一の部材５１の壁孔閉塞用蓋１０における蓋盤部１４の裏面側から第一貫通孔２７に挿通させて、バンド部３６の先端部側を蓋盤部１４の表面側に突出させる。このとき、バンド部３６の係止溝３７が、第一の部材５１の壁孔閉塞用蓋１０に固着された連結部材３５の係止舌片４０に噛合して係止される。   Next, the operator places the wall hole closing lid 10 of the first member 51 in the state in which the wall hole closing lid 10 of the second member 52 is aligned in the vertical direction (that is, FIGS. 7 and 8). In FIG. 1 to FIG. 4, the vertical direction is maintained, and the wall 13 is brought close to the opening 13. Then, the leading end portion of the band portion 36 of the second member 52 is inserted into the first through hole 27 from the back surface side of the lid portion 14 in the wall hole closing lid 10 of the first member 51, and the band portion 36 is inserted. The front end side of the head is projected to the surface side of the cover part 14. At this time, the locking groove 37 of the band portion 36 is engaged and locked with the locking tongue piece 40 of the connecting member 35 fixed to the wall hole closing lid 10 of the first member 51.

この状態で、第二の部材５２の壁孔閉塞用蓋１０と同様の手順により、第一の部材５１の壁孔閉塞用蓋１０を弾性片部１９を壁孔１２の内部に挿入し、図７及び図８に示すように、蓋盤部１４が開口部１３の全面を塞いだ状態で壁孔閉塞用蓋１０を壁孔１２に止着する。なお、図７及び図８においては、一対の壁孔閉塞用蓋１０，１０のうち図中右側に示されているのが第一の部材５１の壁孔閉塞用蓋１０に該当する。更に、作業者は、第一の部材５１の壁孔閉塞用蓋１０の蓋盤部１４を回転させて、第二の部材５２の壁孔閉塞用蓋１０と上下方向の向きが一致した状態になるように調整する。   In this state, the elastic hole 19 is inserted into the wall hole 12 and the wall hole closing lid 10 of the first member 51 is inserted into the wall hole 12 by the same procedure as the wall hole closing lid 10 of the second member 52. 7 and FIG. 8, the wall hole closing lid 10 is fixed to the wall hole 12 in a state in which the lid 14 closes the entire surface of the opening 13. 7 and 8, the wall hole closing lid 10 of the first member 51 is shown on the right side of the pair of wall hole closing lids 10, 10. Further, the operator rotates the cover plate portion 14 of the wall hole closing lid 10 of the first member 51 so that the vertical direction coincides with the wall hole closing lid 10 of the second member 52. Adjust so that

以上の手順により、図７及び図８に示す通り、壁孔１２の両方の開口部１３が一対の壁孔閉塞用蓋１０，１０によってそれぞれ塞がれた状態となる。   By the above procedure, as shown in FIGS. 7 and 8, both the openings 13 of the wall hole 12 are closed by the pair of wall hole closing lids 10, 10.

この状態において、壁孔閉塞用蓋１０の一対の弾性片部１９，１９がそれぞれ固定部１８方向に弾性変形し、壁孔１２の内周部に圧接されることになる。このとき、一対の弾性片部１９，１９がそれぞれ弾性変形することになるため、それぞれの弾性片部１９，１９の撓み量は小さくて済む。また、それぞれの止着片部１６，１６は蓋盤部１４の仮想中心点１７を基準として略対称位置に配設されているため、それぞれの弾性片部１９,１９の弾性力は蓋盤部１４の仮想中心点１７方向に向けて均等に加わる。そのため、壁孔閉塞用蓋１０を壁孔１２に装着した際、壁孔１２の中心と蓋盤部１４の仮想中心点１７との位置は、おのずと略一致した状態になる。   In this state, the pair of elastic pieces 19, 19 of the wall hole closing lid 10 are elastically deformed in the direction of the fixed portion 18, and are pressed against the inner peripheral portion of the wall hole 12. At this time, since the pair of elastic pieces 19 and 19 are elastically deformed, the amount of bending of the elastic pieces 19 and 19 can be small. In addition, since the fastening piece portions 16 and 16 are disposed at substantially symmetrical positions with respect to the virtual center point 17 of the lid plate portion 14, the elastic force of the elastic piece portions 19 and 19 is applied to the lid plate portion. 14 are added equally toward the direction of the virtual center point 17. Therefore, when the wall hole closing lid 10 is attached to the wall hole 12, the positions of the center of the wall hole 12 and the virtual center point 17 of the cover board portion 14 are substantially coincident with each other.

そして、作業者は、第一の部材５１の壁孔閉塞用蓋１０における蓋盤部１４の表面側から突出しているバンド部３６の先端部側を把持し、バンド部３６を蓋盤部１４の表面側に引き出して、壁孔１２の内部でたるんでいるバンド部３６を緊張した状態にする。第一の部材５１の連結部材３５の係止舌片４０はバンド部３６の係止溝３７に噛合してバンド部３６を係止し、バンド部３６が緊張した状態が保持される。これにより、バンド部３６の緊張によって一対の壁孔閉塞用蓋１０,１０が壁孔１２に止着された状態が保持されることとなり、壁孔１２に止着された一対の壁孔閉塞用蓋１０,１０が壁孔１２から落下してしまうような事態を防止できる。更に、作業者は、図７及び図８に示すように、第一の部材５１の第一貫通孔２７から蓋盤部１４の表面側に引き出されたバンド部３６を折り返して第二貫通孔２８から壁孔１２の内部に挿通させ、バンド部３６の先端部側を壁孔１２の内部に収納する。これにより、蓋盤部１４の外側に長いバンド部３６が露出して美観が損なわれる事態を防ぐことができる。   Then, the operator grasps the front end side of the band portion 36 protruding from the surface side of the lid plate portion 14 in the wall hole closing lid 10 of the first member 51, and holds the band portion 36 of the lid plate portion 14. The band portion 36 that is pulled out to the front surface side and slacks inside the wall hole 12 is in a tensioned state. The locking tongue piece 40 of the connecting member 35 of the first member 51 meshes with the locking groove 37 of the band part 36 to lock the band part 36, and the band part 36 is kept in a tensioned state. Thus, the state in which the pair of wall hole closing lids 10 and 10 are fixed to the wall hole 12 by the tension of the band portion 36 is maintained, and the pair of wall hole closing sounds fixed to the wall hole 12 is retained. A situation in which the lids 10, 10 fall from the wall hole 12 can be prevented. Further, as shown in FIGS. 7 and 8, the operator turns back the band portion 36 drawn out from the first through hole 27 of the first member 51 to the surface side of the lid plate portion 14 to return the second through hole 28. The tip of the band portion 36 is accommodated in the wall hole 12. Thereby, the situation where the long band part 36 is exposed to the outside of the lid part 14 and the aesthetic appearance is impaired can be prevented.

以上の作業が完了したのち、作業者は第一の部材５１の壁板閉塞用蓋１０の蓋部３４を凹部２６に嵌合させて、蓋部３４を閉じる。これにより、蓋盤部１４の表面側から見て、連結部材３５や連結部材３５が貫通した各貫通孔２７，２８，４３は、蓋部３４によって隠された状態となる。   After the above operation is completed, the operator closes the lid 34 by fitting the lid 34 of the wall plate closing lid 10 of the first member 51 into the recess 26. Thereby, when viewed from the front surface side of the lid part 14, the connection member 35 and the through holes 27, 28, and 43 through which the connection member 35 penetrates are hidden by the lid part 34.

このように、この実施の形態においては、第二の部材５２の壁孔閉塞用蓋１０を壁孔１２の一方側の開口部１３に取り付けたのち、第一の部材５１の壁孔閉塞用蓋１０を壁孔１２の他方側の開口部１３に取り付けることができる。即ち、壁孔１２の両側開口部１３，１３に一対の壁孔閉塞用蓋１０，１０をそれぞれ取り付ける作業を、壁孔１２の一方側の開口部１３への取付作業と、他方側の開口部１３への取付作業とを順番に行うことができるため、仮に作業者が一人だけであっても作業を容易に行うことができる。   Thus, in this embodiment, the wall hole closing lid 10 of the second member 52 is attached to the opening 13 on one side of the wall hole 12, and then the wall hole closing lid of the first member 51 is attached. 10 can be attached to the opening 13 on the other side of the wall hole 12. That is, the operation of attaching the pair of wall hole closing lids 10 and 10 to the both side openings 13 and 13 of the wall hole 12 is the same as the operation of attaching the wall hole 12 to the opening 13 on one side and the opening on the other side. Therefore, even if there is only one worker, the work can be easily performed.

ところで、例えば壁孔１２の開口部１３の開口径が蓋盤部１４の直径に対して非常に小さい場合には、蓋盤部１４の外周部分は開口部１３を塞ぐためには不要となる。一方、壁孔１２が障害物（例えば建物の天井や庇など）に近接して設けられている場合には、壁孔閉塞用蓋１０を壁孔１２の開口部１３に取り付けようとすると、蓋盤部１４の一部が障害物に接触してしまって開口部１３と蓋盤部１４との間に隙間ができてしまったり、壁孔閉塞用蓋１０を壁孔１２の開口部１３に取り付けることができない事態が起こりうる。このような場合、作業者は、切取溝３３に沿って蓋盤部１４の一部を切り取ることで、蓋盤部１４の開口部１３を塞ぐために必要のない一部を切除する。そして、作業者は蓋盤部１４の一部を切除した壁孔閉塞用蓋１０を壁孔１２の開口部１３に取り付ける。このようにすることで、蓋盤部１４の一部が障害物に接触することを防止しつつ、壁孔１２の開口部１３を塞ぐことができる。   By the way, for example, when the opening diameter of the opening portion 13 of the wall hole 12 is very small with respect to the diameter of the cover plate portion 14, the outer peripheral portion of the cover plate portion 14 is not necessary for closing the opening portion 13. On the other hand, when the wall hole 12 is provided in the vicinity of an obstacle (for example, a ceiling or a fence of a building), when the wall hole closing lid 10 is attached to the opening 13 of the wall hole 12, the lid A part of the board part 14 comes into contact with an obstacle to create a gap between the opening part 13 and the cover board part 14, or the wall hole closing lid 10 is attached to the opening part 13 of the wall hole 12. Things that can't be done can happen. In such a case, the operator cuts out a part of the cover board part 14 along the cut groove 33 to cut out a part that is not necessary for closing the opening part 13 of the cover board part 14. Then, the operator attaches the wall hole closing lid 10, which is a part of the lid 14, to the opening 13 of the wall hole 12. By doing in this way, the opening part 13 of the wall hole 12 can be plugged, preventing a part of the cover part 14 from contacting an obstacle.

以上示した通り、この実施の形態においては、止着手段１５は、蓋盤部１４の中央部側に立設された固定部１８と、弾性変形可能な板状体からなり、一端部が固定部１８に接合すると共に他端部側は蓋盤部１４の外周部方向に向けて延長し、壁孔１２の内部に圧接される弾性片部１９とを有する止着片部１６を一対備えたことにより、壁孔１２に止着手段１５を挿入したときに一対の弾性片部１９，１９がそれぞれ固定部１８方向に弾性変形し、壁孔１２の内周部に圧接されることになる。このとき、一対の弾性片部１９，１９がそれぞれ弾性変形することになるため、それぞれの弾性片部１９，１９の撓み量は小さくて済み、撓みによる弾性片部１９の負荷が過大になることを防止できる。また、それぞれの止着片部１６，１６は蓋盤部１４の仮想中心点１７を基準として略対称位置に配設され、壁孔１２に装着される前の状態において壁孔１２の中心と蓋盤部１４の仮想中心点１７とを一致させた際に、それぞれの弾性片部１９，１９の先端部２２，２２が壁孔１２の開口部１３の周縁部２３よりも外方に突出されると共に、壁孔１２に装着された状態において、それぞれの弾性片部１９，１９の先端部２２，２２が蓋盤部１４の仮想中心点１７方向に弾性変形して壁孔１２の内部に圧接されて止着されるように形成されたことにより、壁孔１２の中心位置と蓋盤部の仮想中心点１７とを略一致させた状態で壁孔閉塞用蓋１０を壁孔１２に取り付けることができる。そのため、壁孔１２の開口径が大きい場合でも、壁孔１２の開口部１３の一部が蓋盤部１４の外にはみ出してしまう事態を簡単に防止できる。さらに、弾性片部１９には押圧部材や係止片のように複雑な構成が設けられていないため、壁孔閉塞用蓋１０を製造する際に複雑な構成の金型を用いる必要がなく、製造コストの高騰を抑止できる。これにより、簡易な構成で低コストで製造できて、壁孔の大きさに拘わらず壁孔を隙間なく塞ぐことができて、繰り返しの使用や長年の使用によっても劣化や破損が起こりにくく、簡易に壁孔に取り付けることができる壁孔閉塞用蓋を提供することができる。   As described above, in this embodiment, the fastening means 15 is composed of the fixing portion 18 erected on the center side of the lid plate portion 14 and the plate body that can be elastically deformed, and one end portion is fixed. A pair of fastening pieces 16 each having an elastic piece 19 that is joined to the portion 18 and extends toward the outer peripheral portion of the lid 14 and is pressed into the wall hole 12 are provided. As a result, when the fastening means 15 is inserted into the wall hole 12, the pair of elastic pieces 19, 19 are elastically deformed in the direction of the fixed portion 18, and are pressed against the inner peripheral portion of the wall hole 12. At this time, since the pair of elastic pieces 19 and 19 are elastically deformed, the amount of bending of the elastic pieces 19 and 19 is small, and the load on the elastic pieces 19 due to the bending becomes excessive. Can be prevented. Further, the fastening pieces 16, 16 are disposed substantially symmetrically with respect to the virtual center point 17 of the lid 14, and the center of the wall hole 12 and the lid before being attached to the wall hole 12. When the virtual center point 17 of the board part 14 is made to coincide with each other, the tip parts 22 and 22 of the respective elastic piece parts 19 and 19 protrude outward from the peripheral part 23 of the opening part 13 of the wall hole 12. At the same time, in the state of being mounted in the wall hole 12, the tip portions 22, 22 of the respective elastic piece portions 19, 19 are elastically deformed in the direction of the imaginary center point 17 of the cover plate portion 14 and are pressed into the wall hole 12. The wall hole closing lid 10 can be attached to the wall hole 12 in a state where the center position of the wall hole 12 and the virtual center point 17 of the cover board portion are substantially coincided with each other. it can. Therefore, even when the opening diameter of the wall hole 12 is large, it is possible to easily prevent a situation in which a part of the opening 13 of the wall hole 12 protrudes outside the lid part 14. Furthermore, since the elastic piece portion 19 is not provided with a complicated configuration such as a pressing member or a locking piece, it is not necessary to use a mold having a complicated configuration when manufacturing the wall hole closing lid 10, Increase in manufacturing costs can be prevented. As a result, it can be manufactured at a low cost with a simple configuration, and the wall hole can be closed without any gap regardless of the size of the wall hole, and it is not easily deteriorated or damaged by repeated use or long-term use. A wall hole closing lid that can be attached to the wall hole can be provided.

また、この実施の形態においては、一対の弾性片部１９，１９は、それぞれの板面を略平行に対向させて配設されると共に、それぞれの先端部２２，２２はそれぞれの基端部２１，２１同士を結ぶ仮想線２５に対してそれぞれ反対方向に向けて延長されたことにより、壁孔１２に止着手段１５を嵌挿させて壁孔１２にそれぞれの弾性片部１９，１９を圧着させたとき、蓋盤部１４の仮想中心点１７に対して略対称の位置から蓋盤部１４の仮想中心点１７方向に向けてそれぞれ略等しい弾性力を加えることができる。これにより、壁孔閉塞用蓋１０を壁孔１２に取り付けたときに、それぞれの弾性片部１９，１９の弾性力のみによって、壁孔１２の中心位置と蓋盤部の仮想中心点１７を容易に略一致させることでき、壁孔１２の大きさに拘わらず確実に壁孔を隙間なく塞ぐことができて、一層簡易に壁孔１２に取り付けることができる壁孔閉塞用蓋１０を提供することができる。   Further, in this embodiment, the pair of elastic pieces 19 and 19 are disposed with their plate surfaces facing each other substantially in parallel, and the respective distal end portions 22 and 22 are each proximal end portion 21. , 21 are extended in opposite directions with respect to the imaginary line 25, so that the fastening means 15 is inserted into the wall hole 12 and the elastic pieces 19, 19 are crimped to the wall hole 12. When this is done, substantially the same elastic force can be applied from the substantially symmetric position to the virtual center point 17 of the cover board part 14 toward the virtual center point 17 direction of the cover board part 14. As a result, when the wall hole closing lid 10 is attached to the wall hole 12, the center position of the wall hole 12 and the virtual center point 17 of the cover panel portion can be easily set only by the elastic force of the respective elastic pieces 19 and 19. To provide a wall hole closing lid 10 that can be substantially matched with each other, can reliably close the wall hole regardless of the size of the wall hole 12, and can be attached to the wall hole 12 more easily. Can do.

A first through hole 27, a second through hole 28, and a third through hole 43 are formed through which the connecting members 35 for connecting the respective wall hole closing lids 10, 10 to each other in a state of being mounted, A cap member 30 that is fitted into the recess 26 in a state of covering each of the through holes 27, 28, 43 is provided, and an attachment piece 31 is extended to the cap member 30, In the case of insertion into the mounting hole 29 formed in the recess 26, the retaining part 32 is elastically deformed so that the retaining part 32 can be inserted into the mounting hole 29. After the insertion is completed, the retaining portion 32 returns to its original state and is removed. By forming the portion 29 to be locked, the retaining portion 32 is inserted into the mounting hole 29 by press-fitting the retaining portion 32 into the mounting hole 29, and the retaining portion 32 penetrating the mounting hole 29 is retained. Can be made. Therefore, the attaching process of the cap member 30 can be easily performed only by press-fitting the retaining portion 32. Then, by fitting the cap member 30 with the retaining portion 32 locked into the recess 26, the connecting member 35 and the through holes 27, 28, 43 through which the connecting member 35 penetrates are exposed to the outside and the aesthetic appearance is impaired. The situation can be prevented.

この実施の形態においては、蓋盤部１４の板面の外周部近傍には、蓋盤部１４の一部を切除するための直線状の切取溝３３が陥没形成されていることにより、蓋盤部１４の切取溝よりも外周部側を容易に切除することが可能になる。これにより、蓋盤部１４のうち壁孔１２を塞ぐために必要のない部分が生じた際に蓋盤部１４の一部を切除する作業を容易に行うことができて、壁孔閉塞用蓋１０を一層簡易に壁孔に取り付けることができる。   In this embodiment, in the vicinity of the outer peripheral portion of the plate surface of the lid plate portion 14, a linear cut groove 33 for excising a part of the lid plate portion 14 is formed to be depressed, so that the lid plate It becomes possible to easily cut the outer peripheral portion side than the cut groove of the portion 14.
