Description

【０００１】
【発明の属する技術分野】
本発明は壁面に鏡を取付けるための鏡止め具に関する。
【０００２】
【従来の技術】
一般に、鏡は下部の受け具と上部の鏡止め具とで壁面に取付けられ、鏡止め具は鏡に対して上下スライド可能とされている（鏡止め具に設けた長孔を通して止めねじで壁面に固定され、この止めねじを緩めることで長孔の範囲で鏡止め具がスライドする。）。
しかし、上記従来の技術では、取付け当初は問題ないが、長期使用中に繰返し鏡面を雑巾で拭くなどすると、止めねじが緩み鏡止め具が移動し易くなり、わずかな外力（鏡面を雑巾で上下に拭いた場合等）で持上がる恐れがあった。鏡止め具が徐々に鏡の上縁から上方へ離れ、見苦しくなる。
【０００３】
この問題点を解決しようとするものに、実開平３−１２９３６１号公報（鏡固定具）の技術があり、この公報の図１によれば、フック部材（鏡止め具に相当）１０の上側に鏡係止部１０ａを形成し且つ下側に付勢部材固定部１２を形成し、フック部材１０をこれに設けた長孔１１を通して壁面にねじ３で緩く止め、このねじ３に移動防止用付勢部材（ねじりばね）２０の一端の輪２３を係止し、移動防止用付勢部材２０の他端をフック部材１０の付勢部材固定部１２に挿入することで、フック部材１０を下方へ弾発させたものである。
鏡Ｍを鏡固定具で壁面Ｗに取付ける手順は、第３図に示すように▲１▼フック部材１０を摘んで持上げ、▲２▼鏡Ｍを壁面Ｗにセットし、▲３▼摘んでいた手を放すこと（移動防止用付勢部材２０の弾発力でフック部材１０が下降して鏡Ｍの上縁に係止）である。
【０００４】
【発明が解決しようとする課題】
このような鏡固定具は、わずかな外力でフック部材１０が持上がることを防止するために、フック部材１０を下方へ弾発させるための移動防止用付勢部材２０の弾発力は、大きいことが求められる。
一方、鏡Ｍを壁面Ｗに取付けるには、持上げられたフック部材１０を鏡の上縁に係止するものであり、摘んでいた手を放すと、フック部材１０は移動防止用付勢部材２０の弾発力で勢いよく鏡Ｍの上縁に当たる。このため、当たった衝撃が大きいと鏡Ｍの縁が欠ける恐れがあるので、移動防止用付勢部材２０の弾発力は大き過ぎないことが好ましい。しかし、持上がり防止のためには、移動防止用付勢部材２０の弾発力を小さくできない。
これを補うためには、フック部材１０の掛止め作業時に、鏡Ｍの上縁に衝撃を与えないようにゆっくり降ろすなど注意を払う必要があり、作業が煩わしい。
【０００５】
そこで本発明の目的は、（１）壁に鏡を取付ける際に、鏡の縁に衝撃を与えないように注意を払う必要がないこと、（２）可動部材がわずかな外力で持上がる恐れがなく、鏡の上縁を確実に止めることができることにある。
【０００６】
【課題を解決するための手段】
上記目的を達成するために請求項１記載の発明は、壁面にねじ止めされ、前面にばね受部及び縦ガイド溝が起設された固定部材と、前記縦ガイド溝で上下動のみ可能にガイドされ、前面にばね掛け部が起設された可動部材と、前記可動部材の上部に設けられ、鏡の上縁に係止する鉤部と、前記ばね受部と前記ばね掛け部とに掛けられ、前記固定部材に上下動のみ可能に嵌合された状態の可動部材を下方へ弾発するばねとからなる鏡止め具において、前記ばねの弾発力を変化させる弾発力変化機構を設けたことを特徴とする。
ばねの弾発力が変化するので、鉤部が下降する際の速度を制限することができる。このため、鏡の上縁に鉤部を当接した瞬間の鏡への衝撃を弱めることができる。
しかも、ばねの弾発力を変化させることができるので、可動部材の持上がりに対する弾発力を大きく設定することができる。このため、可動部材がわずかな外力で持上がる恐れがない。
【０００７】
さらに請求項１記載の発明は、前記ばねを線材または帯材で左右対称の略逆Ｖ字状に形成し、ばねの両端側を前記固定部材の左右側に有する前記ばね受部に掛け、且つ中央側を前記可動部材の左右方向中央に有する前記ばね掛け部に掛けるものとし、更に、前記ばねの両端側に、下方へ略ハ字形に開かれた第１下降作用部と、この第１下降作用部の上部で第１下降作用部よりも略ハ字形の開き角が大きい第２下降作用部とを形成することで、前記鉤部が鏡の上縁に係止する下部位置にあるときに左右側に開き且つ鉤部が鏡の上縁から外れた上部位置にあるときに前記ばね受部との係合により左右方向中央に絞られる構成とし、前記弾発力変化機構を、前記第１・第２下降作用部と前記ばね受部とで構成したことを特徴とする。
第２下降作用部の方が第１下降作用部よりも開き角が大きいので、下方への弾発力も大きい。
可動部材を下降させた場合に、ばねは最初に弾発力の小さな第１下降作用部がばね受部と係合しながら下降し、次に弾発力の大きな第２下降作用部がばね受部と係合しながら下降する。このため、鉤部は最初の所定時間に比較的低速で下降し、次にこれよりも高速で下降して鏡の上縁に当接する。従って、鉤部が高速で下降しても加速時間が短いので、鏡の上縁に当接する瞬間の最終速度は比較的低速ですむ。これにより、鉤部が鏡の上縁に当接した瞬間の衝撃は弱まる。
また、鏡が鏡止め具で壁面に取付けられた状態では、弾発力の大きな第２下降作用部がばね受部と係合しているので、可動部材の持上がりに対する弾発力が大きい。このため、可動部材がわずかな外力で持上がる恐れはない。
【０００８】
請求項２記載の発明は、前記ばねの両端側に且つ前記第２下降作用部の上部に、ばねの左右方向外側に突出した円弧状の第３下降作用部を形成したことを特徴とする。
ばねに円弧状の第３作用部を形成したので、鏡の上縁に当接する瞬間の最終速度が一層低速になる。このため、鏡の上縁に鉤部を当接した瞬間の鏡への衝撃が一層弱まる。
【００１０】
請求項３記載の発明は、壁面にねじ止めされ、前面にばね受部及び縦ガイド溝が起設された固定部材と、前記縦ガイド溝で上下動のみ可能にガイドされ、前面にばね掛け部が起設された可動部材と、前記可動部材の上部に設けられ、鏡の上縁に係止する鉤部と、前記ばね受部と前記ばね掛け部とに掛けられ、前記固定部材に上下動のみ可能に嵌合された状態の可動部材を下方へ弾発するばねとからなる鏡止め具において、前記ばねの弾発力を変化させる弾発力変化機構を設け、
前記ばねを線材または帯材で左右対称の略逆Ｖ字状に形成し、ばねの両端側を前記固定部材の左右側に有する前記ばね受部に掛け、且つ中央側を前記可動部材の左右方向中央に有する前記ばね掛け部に掛けるものとし、更に、前記両端側に、下方へ略ハ字形に開かれた下降作用部を形成されることで、前記鉤部が鏡の上縁に係止する下部位置にあるときに左右側に開き且つ鉤部が鏡の上縁から外れた上部位置にあるときに前記ばね受部との係合により左右方向中央に絞る構成とし、しかも、前記ばねの表面に所定の摩擦抵抗を有する被膜を施し、前記弾発力変化機構を、前記被膜を施されたばねの下降作用部と前記ばね受部とで構成したことを特徴とする。
表面に所定の摩擦抵抗を有する被膜を施されたばねの下降作用部とばね受部との摩擦力によって、ばねの弾発力を変化させることができるので、ばねがシンプルな形状であるにもかかわらず、鉤部が下降する際の速度を制限することができる。また、可動部材の持上がりに対しても、ばねとばね掛け部との摩擦力が作用するので、可動部材の持上がりに対する抵抗力が一層大きくなる。
【００１４】
【発明の実施の形態】
本発明の実施例を添付図面に基づいて以下に説明する。
先ず、第１実施例を図１〜図７に基づいて説明する。
図１は本発明に係る鏡止め具（第１実施例）による鏡の取付け構造の斜視図であり、鏡１は壁面２に下部受け具４及び鏡止め具１０で取付けられている。下部受け具４は鏡１の下縁を受け、鏡止め具１０は鏡１の上縁を止めるものである。
【００１５】
図２は本発明に係る鏡止め具（第１実施例）の分解斜視図であり、鏡止め具１０は、壁面２（図１参照）に取付けられる固定部材１１と、この固定部材１１に上下動のみ可能にガイドされる可動部材３１と、固定部材１１と可動部材３１との間に掛けられるばね４１とからなる。
【００１６】
固定部材１１は、前面視略エ字形を呈する平板状の固定本体１２（上部水平部１２ａとその下の垂直部１２ｂとその下の下部水平部１２ｃからなる）と、垂直部１２ｂ前面の左右に形成された一対の縦ガイド溝１３，１３と、これらの縦ガイド溝１３，１３の下側に起設された一対の平面視Ｌ字状のばね受部１４，１４と、垂直部１２ｂの上部に開けられたねじ用孔１５と、下部水平部１２ｃの下部から前側（図４にて説明する鏡１の裏側）に向って起設された押圧アーム１６と、下部水平部１２ｃの左右両端に設けられた保持部１７，１７とからなり、鋼板等の板材から一体に折り曲げ成形される。
【００１７】
各縦ガイド溝１３，１３は、上・下水平部１２ａ，１２ｃと逆Ｌ字状のガイド部１８，１８によって形成される。ねじ用孔１５には止めねじ２１が挿通される。押圧アーム１６の先端部１６ａは、想像線で示す軟質樹脂製被膜のクッション２２で被覆されている。
垂直部１２ｂ及び押圧アーム１６は止めねじ２１の位置を支点として前後に弾性変形可能であり、保持部１７，１７も押圧アーム１６の変形時に同一方向に弾性変形可能である。
【００１８】
固定部材１１は壁面２（図１参照）に取付けるための取付面に１つの凸部２３を備えている。すなわち、下部水平部１２ｃの裏面には、左右方向中央に且つねじ用孔１５と押圧アーム１６との間に、半球状の凸部２３が一体に形成されている。
【００１９】
可動部材３１は平板状の可動本体３２と、この可動本体３２の下側に延びた左右一対の脚部３３，３３と、これらの脚部３３，３３の下部に形成された圧接部３４，３４と、可動本体３２の上端前面に略コ字状断面に起設された鉤部３５と、可動本体３２の左右方向中央に且つ鉤部３５の近傍に起設されたばね掛け部３６とからなり、鋼板等の板材から一体に折り曲げ成形される。
可動部材３１は上下動のみ可能にガイドされるために、各脚部３３，３３が各縦ガイド溝１３，１３に嵌合されている。
【００２０】
圧接部３４，３４は保持部１７，１７に摩擦力でロックされるものであり、突出した表面が半球状である。圧接部３４，３４は、例えばエンボス加工にて成形される。そして、固定部材１１の保持部１７と可動部材３１の圧接部３４との組合せは、鏡取付け前の鉤部３５が下降せぬようにロックするロック機構を構成し、このロック機構は摩擦力でロック状態を維持する。
なお、３２ａは可動部材３１が上下動した際に止めねじ２１に当たらないための凹部、３７は可動本体３２にばね掛け部３６を起設するための切抜き孔である。
【００２１】
ばね４１は、ばね性を有する線材（例えば、ピアノ線）または帯材により、左右対称の略逆Ｖ字状（概ねΩ字に類似した形状）に形成されている。すなわち、ばね４１は中央部４２が下向きの略ヘアピン形であり、両端側には、最下端の端末部４３，４３と、この端末部４３，４３の上部の第１下降作用部（傾斜部）４４，４４と、この第１下降作用部４４，４４の上部の第２下降作用部（傾斜部）４５，４５とを一体に形成してなる。
【００２２】
端末部４３，４３は折返された形状であり、第１下降作用部４４，４４は斜め下方へ略ハ字形に開かれた形状であり、第２下降作用部４５，４５は斜め下方へ開かれ第１下降作用部よりも開き角が大きい略ハ字形の形状である。これらの端末部４３及び第１・第２下降作用部４４，４５は、ばね４１の左右方向に形成される。そして、ばね４１は第１下降作用部４４，４４同士、第２下降作用部４５，４５同士が離反する方向に弾発されている。
【００２３】
ばね４１は、両端側（第１・第２下降作用部４４，４５）を固定部材１１のばね受部１４，１４に掛けられ、中央部４２を可動部材３１のばね掛け部３６に掛けられることで、固定部材１１に上下動のみ可能に嵌合された状態の可動部材３１を下方へ弾発する。
このように、ばね４１は、鉤部３５が鏡１の上縁に係止する下部位置にあるときに左右側に開き、且つ鉤部３５が鏡１の上縁から外れた上部位置にあるときにばね受部１４，１４との係合により左右方向中央に絞られる構成である。
【００２４】
このため、ばね４１の弾発力は、第２下降作用部４５，４５がばね受部１４，１４に係合している状態の方が、第１下降作用部４４，４４がばね受部１４，１４に係合している状態よりも大きくなるように変化する。
そして、ばね受部１４と第１・第２下降作用部４４，４５とからなる構成は、ばね４１の弾発力を変化させる弾発力変化機構を構成する。
【００２５】
図３は図１の３−３線拡大断面図であり、下部受け具４は略Ｊ字状断面を呈し、裏面が止めねじ５で壁面２に取付けられ、鏡１の下縁とクッション６とを挟持し且つ受けている。下部受け具４は鋼板等の板材から一体に折り曲げ成形され、前後方向（この図の左右方向）に弾性変形可能である。
下部受け具４の裏面には、止めねじ５を挟んだ上下２箇所に半球状の凸部７，７が一体に形成されている。
【００２６】
一方、壁面２には鏡止め具１０の固定部材１１が、止めねじ２１で取付けられている。
鏡１の上縁は可動部材３１の鉤部３５で係止され、押圧アーム１６は鏡１で押圧されて壁面２側に弾性変形している。
【００２７】
図４（ａ），（ｂ）は本発明に係る可動部材の鉤部（第１実施例）の構成図及び作用図であり、（ａ）は鉤部が鏡の上縁から外れた状態を示し、（ｂ）は鉤部が鏡の上縁に係止した状態を示す。
鉤部３５は鏡１の上端面１ａと対向する面に凸部３８を備え、この凸部３８は鏡１の上端面１ａの厚み方向（この図の左右方向）略中央又は中央より後部に当接するものである。すなわち、凸部３８は鉤部３５の左右（この図の前後）に貫通して一体に形成され、その断面形状は下向き半円状である。１条の凸部３８は（ｂ）に示すように、鏡１の板厚中心から寸法Ｓだけ後部にオフセットしている。
【００２８】
次に弾発力変化機構の作用を図５に基づき説明する。
図５（ａ）〜（ｃ）は本発明に係る弾発力変化機構（第１実施例）の作用説明図である。
（ａ）は、ばねが最も上部位置にある状態を示し、鉤部３５が上部位置から下降を開始するときに相当する。
（ｂ）は、ばねが下降途中にある状態を示す。
（ｃ）は、ばねが最も下部位置にある状態を示し、鉤部３５が鏡１の上縁に係止する下部位置にあるときに相当する。
【００２９】
（ａ）の状態で、第１下降作用部４４，４４がばね受部１４，１４と係合しているので、ばね４１は左右方向中央に絞られている。
この状態では、中央部４２は自己の弾発力で拡がり、この時の水平分力により第１下降作用部４４，４４はばね受部１４，１４に沿って外側に移動する。このため、ばね４１は下降するが、下方への弾発力が小さいので比較的低速である。
【００３０】
ばね４１は下降途中で（ｂ）に示すように、ばね受部１４，１４に対して第１下降作用部４４，４４から第２下降作用部４５，４５への係合に移行する。第２下降作用部４５，４５は第１下降作用部４４，４４よりも開き角度が大きいので、水平分力も大きく、下方への弾発力が大きい。このため、第２下降作用部４５，４５ははばね受部１４，１４に沿って外側に急速に移動する。従って、ばね４１は引続き下降するが、下方への弾発力が大きいので比較的高速である。
【００３１】
その後、ばね４１は（ｃ）に示すように、ばね受部１４，１４に対して第２下降作用部４５，４５の上部の係合に移行し、下降を停止する。
このように、ばね４１の弾発力は、第２下降作用部４５，４５がばね受部１４，１４に係合している状態の方が、第１下降作用部４４，４４がばね受部１４，１４に係合している状態よりも大きくなるように変化する。
【００３２】
次に、上記構成の下部受け具４及び鏡止め具１０による鏡１の取付け構造の組付け手順を説明する。
先ず、図１に示すように、壁面２に下部受け具４を取付け、次に、鏡止め具１０を壁面２に位置合せし、これを取付ける。
次に、鏡止め具１０の取付け手順を説明する。図６及び図７は本発明に係る鏡止め具（第１実施例）の作用説明図である。
【００３３】
鏡止め具１０は、図６に示すように固定部材１１の縦ガイド溝１３，１３に可動部材３１の脚部３３，３３を挿通し、次に、ばね４１の中央部４２をばね掛け部３６に掛け、その後、ばね４１の両端を圧縮しながら両端側（第２下降作用部４５の上部）をばね受部１４に掛けることで組立てられる。組立てられた鏡止め具１０は止めねじ２１で壁面２に取付けられる（図３参照）。
【００３４】
その後、可動部材３１の鉤部３５を摘んで持上げると、可動部材３１は図７に示す上部位置に上がる。同時に、ばね４１の両端側はばね受部１４，１４に沿って内側に移動する。この上部位置において、可動部材３１は保持部１７と圧接部３４とが圧接することによる摩擦力でロックされており、摘んでいた手を放しても下降しない。
【００３５】
鏡１の上縁を合せた後、可動部材３１の鉤部３５を押下げると、保持部１７と脚部３３，３３とが互いに相反する方向に弾性変形する。このため、保持部１７と圧接部３４とは摩擦力によるロックが外れる。従って、可動部材３１はばね４１の弾発力で引き下げられる。
すなわち図６に示すように、ばね４１の中央部４２は自己の弾発力で拡がり、この時の水平分力により両端側はばね受部１４，１４に沿って外側に移動する。このため、ばね４１は可動部材３１を引き下げる。従って、可動部材３１は自動的に引き下げられて、鉤部３５が鏡１の上縁に係止する。
以上で組立作業を完了する。
【００３６】
ところで、図７に示す状態から可動部材３１を下降させた場合に、鉤部３５は下降最初の所定時間（第１下降作用部４４，４４がばね受部１４，１４に沿って下降する時間）に比較的低速で下降し、その後、次の所定時間（第２下降作用部４５，４５がばね受部１４，１４に沿って下降する時間）に比較的高速で下降し、最後に、鏡１の上縁に当接する。
このため、鉤部３５が高速で下降しても加速時間が短いので、鏡１の上縁に当接する瞬間の最終速度は比較的低速ですむ。従って、鏡１の上縁に鉤部３５を当接した瞬間の鏡１への衝撃は弱い。
【００３７】
このように、鏡１への衝撃が弱いので、壁１に鏡を取付ける際に鏡１の上縁に衝撃を与えないように注意を払う必要はない。
しかも、ばね４１の弾発力を変化させることができるので、可動部材３１の持上がりに対する弾発力（抵抗力）を大きく設定することができる。すなわち、図６に示す鏡１が鏡止め具１０で壁面２に取付けられた状態では、弾発力の大きな第２下降作用部４５，４５がばね受部１４，１４と係合しているので、可動部材３１の持上がりに対する弾発力が大きい。このため、可動部材３１はわずかな外力で持上がる恐れがなく、鏡１の上縁を確実に止めることができる。
【００３８】
一方、図４（ａ）に示すように、鉤部３５が鏡１の上縁から外れた状態からばねの弾発力で下降した際に、（ｂ）に示すように凸部３８は鏡１の上端面１ａに当たる。このため、鉤部３５が鏡１の上縁の角部１ｂ，１ｃに衝当することがない。従って、壁面に鏡１を取付ける際に、鏡１の上縁の角部１ｂ，１ｃに衝撃を与えないように注意を払う必要がない。
また、凸部３８が鏡１の上端面１ａの厚み方向略中央又は中央より後部に当接するので、鏡１の前面側の角部１ｂに衝撃が加わるのを一層防止できる。
【００３９】
次に、上記可動部材３１の鉤部３５に備えた凸部３８の変形例を図８〜図１１に基づき説明する。
図８（ａ），（ｂ）は本発明に係る鉤部の凸部（第１実施例）の変形例図であり、（ａ）は可動部材の斜視図、（ｂ）は鉤部の要部断面図である。
鉤部３５の底面には凸部３８Ａが一体に形成され、この凸部３８Ａは鉤部３５の左右方向に所定長さ（鉤部３５の左右に貫通しない長さ）で且つ下向き半円状断面である。
【００４０】
図９（ａ），（ｂ）は本発明に係る鉤部の凸部（第１実施例）の変形例図であり、（ａ）は可動部材の斜視図、（ｂ）は鉤部の要部断面図である。
鉤部３５の底面には凸部３８Ｂが一体に形成され、この凸部３８Ｂは鉤部３５の左右方向中央が最も低い四角錐状である。
【００４１】
図１０（ａ），（ｂ）は本発明に係る鉤部の凸部（第１実施例）の変形例図であり、（ａ）は可動部材の斜視図、（ｂ）は鉤部の要部断面図である。
鉤部３５の底面には別部材からなる凸部３８Ｃが貼り付け等により固定され、この凸部３８Ｃは鉤部３５の左右端にわたって延びる下向き半円状断面であって、ゴム、軟質樹脂等の弾性を有するクッション材からなる。そして、凸部３８Ｃは鉤部３５に貼り付け等により固定される。
【００４２】
図１１（ａ），（ｂ）は本発明に係る鉤部の凸部（第１実施例）の変形例図であり、（ａ）は可動部材の斜視図、（ｂ）は鉤部の要部断面図である。
鉤部３５の底面には別部材からなる凸部３８Ｄが貼り付け等により固定され、この凸部３８Ｄは鉤部３５の下面全体（前後左右）にわたって延びるシート状であって、ゴム、軟質樹脂等の弾性を有するクッション材からなる。そして、凸部３８Ｄは鉤部３５に貼り付け等により固定される。
なお、上記図１０、図１１に示す凸部３８Ｃ，３８Ｄは鏡１の上端面１ａに貼り付け等により固定してもよい。
【００４３】
次に、第２実施例を図１２及び図１３に基づき説明する。なお、上記第１実施例と同構成については同一符号を付し、その説明を省略する。
図１２（ａ），（ｂ）は本発明に係る鏡止め具（第２実施例）の構成図であり、（ａ）は鏡止め具の正面図、（ｂ）はばねの正面図である。
第２実施例は、ばね４１の両端側に且つ第２下降作用部４５，４５の上部に、ばね４１の左右方向外側に突出した円弧状の第３下降作用部４６，４６を一体に形成したことを特徴とする。
そして、ばね受部１４とばね掛け部３６と第１・第２・第３下降作用部４４，４５，４６とからなる構成は、ばね４１の弾発力を変化させる弾発力変化機構を構成する。
【００４４】
次に、第２実施例の作用を図１２及び図１３に基づき説明する。
図１３は本発明に係る鏡止め具（第２実施例）の作用説明図である。
可動部材３１の鉤部３５が図１３に示す上部位置に上がった状態で、鏡１の上縁を合せた後に鉤部３５を押下げると、保持部１７と圧接部３４とは摩擦力によるロックが外れる。従って、可動部材３１はばね４１の弾発力で引き下げられ、図１２（ａ）に示すように鉤部３５が鏡１の上縁に係止される。
【００４５】
この場合、ばね４１はばね受部１４，１４に対して、第１下降作用部４４，４４→第２下降作用部４５，４５→第３下降作用部４６，４６の順で係合関係が移動し、最後に中央部４２の下端が係合する。
このため、ばね４１は第２下降作用部４５，４５がばね受部１４，１４に沿って急速に下降するが、その後、外側に突出した円弧状の第３下降作用部４６，４６がばね受部１４，１４と係合するので、下降速度が再び低速になる。従って、鉤部３５が鏡１の上縁に当接する最終速度は比較的低速ですむ。そして、鏡１の上縁に鉤部３５を当接する衝撃は一層弱くなる。
【００４６】
従って、壁面２に鏡１を取付ける際に、鏡１の上縁に衝撃を与えないように注意を払う必要がない。
しかも、第３下降作用部４６，４６の円弧状の突出高さを大きく設定して、可動部材３１の持上がりに対する弾発力（抵抗力）を大きく設定することができる。このため、可動部材３１がわずかな外力で持上がる恐れがなく、鏡１の上縁を一層確実に止めることができる。
【００４７】
次に、第３実施例を図１４及び図１５に基づき説明する。なお、上記第１実施例と同構成については同一符号を付し、その説明を省略する。
図１４（ａ），（ｂ）は本発明に係る鏡止め具（第３実施例）の構成図であり、（ａ）は正面を示し、（ｂ）は側面を示す。
第３実施例は、側面視湾曲状のばね４１の両端側に、最下端の端末部４３，４３と、この端末部４３，４３の上部の第１下降作用部（下降作用部）４４，４４のみ形成したことを特徴とする。
【００４８】
具体的には、ばね４１は中央部４２の両下端から端末部４３，４３の上部までを第１下降作用部４４，４４とし、この第１下降作用部４４，４４は左右方向に湾曲した（カールされた）形状である。
また、ばね４１は（ｂ）の想像線で示すように、前側（この図の左側）に湾曲した側面視湾曲状（中央部４２の上端から第１下降作用部４４の下端にかけて緩やかに湾曲した形状）に形成されている。
【００４９】
そして、ばね４１は、下降作用部４４が平面視Ｌ字状のばね受部１４に掛けられることで後方（この図の右側）に絞られて、（ｂ）の実線で示すようにやや偏平状に変形した状態でセットされている。
このように組合せられたばね受部１４，１４と第１下降作用部４４，４４とからなる構成は、ばね４１の弾発力を変化させる弾発力変化機構を構成する。

次に、第３実施例の作用を図１４及び図１５に基づき説明する。
図１５（ａ），（ｂ）は本発明に係る鏡止め具（第３実施例）の作用説明図であり、（ａ）は正面を示し、（ｂ）は側面を示す。
可動部材３１の鉤部３５が図１５（ａ）に示す上部位置に上がった状態で、鏡１の上縁を合せた後に鉤部３５を押下げると、保持部１７と圧接部３４とは摩擦力によるロックが外れる。従って、可動部材３１はばね４１の弾発力で引き下げられ、図１４（ａ）に示すように鉤部３５が鏡１の上縁に係止される。
【００５１】
この場合、図１５（ｂ）に示すように鉤部３５が上部位置に上がった状態で、ばね受部１４は第１下降作用部４４の下端と係合している。このため、ばね４１はばね受部１４で絞られていないので、概ね側面視湾曲状である。この状態から、中央部４２は自己の弾発力で図１５（ａ）の左右方向に拡がり、この時の水平分力により第１下降作用部４４，４４はばね受部１４，１４に沿って外側に移動する。このため、ばね４１は下降する。
【００５２】
第１下降作用部４４の下降に伴い、第１下降作用部４４は下部から上部に向ってばね受部１４で絞られるので、側面視偏平状に変形しながら下降する。このため、ばね４１は下降速度を制限されて下降するので、鉤部３５が鏡１の上縁に当接する衝撃を弱めることができる。従って、壁面２に鏡１を取付ける際に、鏡１の上縁に衝撃を与えないように注意を払う必要がなく、取付け作業性が高まる。
【００５３】
また、鏡１が鏡止め具１０で壁面２に取付けられた状態では、第１下降作用部４４はばね受部１４と係合した部分が側面視偏平状に変形しているので、可動部材３１の持上がりに対する弾発力（抵抗力）が大きい。このため、可動部材３１がわずかな外力で持上がる恐れはなく、鏡１の上縁を確実に止めることができる。
この第３実施例によれば、ばね４１を側面視湾曲状にしただけの簡単な構成で、ばね４１の弾発力を変化させることができる。
【００５４】
次に、第４実施例を図１６及び図１７に基づき説明する。なお、上記第３実施例と同構成については同一符号を付し、その説明を省略する。
図１６は本発明に係る鏡止め具（第４実施例）の正面図である。
第４実施例は、上記図１４に示す第３実施例のばね４１を側面視直線状としたものである。すなわち、ばね４１は側面視湾曲状に形成しない構成である。そして、ばね４１は表面に所定の摩擦抵抗を有する被膜を施されたことを特徴とし、被膜は、例えばメッキや樹脂コーティングにて施される。
このように組合せられたばね受部１４，１４と第１下降作用部４４，４４とからなる構成は、ばね４１の弾発力を変化させる弾発力変化機構を構成する。
【００５５】
次に、第４実施例の作用を図１６及び図１７に基づき説明する。
図１７は本発明に係る鏡止め具（第３実施例）の作用説明図である。
可動部材３１の鉤部３５が図１７に示す上部位置に上がった状態で、鏡１の上縁を合せた後に鉤部３５を押下げると、保持部１７と圧接部３４とのは摩擦力によるロックが外れる。従って、可動部材３１はばね４１の弾発力で引き下げられ、図１６に示すように鉤部３５が鏡１の上縁に係止される。
【００５６】
この場合、ばね４１は表面に摩擦抵抗を有する被膜を施されているので、ばね受部１４，１４との滑り摩擦抵抗が大きい。このため、可動部材３１を下降させた場合に、鉤部３５は比較的低速で下降して鏡１の上縁に当接する。従って、鉤部３５が鏡１の上縁に当接する最終速度は比較的低速ですむ。そして、鏡１の上縁に鉤部３５を当接する衝撃は一層弱くなる。
【００５７】
このように、壁面２に鏡１を取付ける際に、鏡１の上縁に衝撃を与えないように注意を払う必要がない。また、可動部材３１の持上がりに対しても、ばね４１とばね受部１４，１４との摩擦力が作用するので、可動部材３１の持上がりに対する弾発力（抵抗力）が一層大きくなる。このため、可動部材３１はわずかな外力で持上がる恐れがなく、鏡１の上縁を確実に止めることができる。
この第４実施例によれば、ばね４１がシンプルな形状であるにもかかわらず、鉤部３５が下降する際の速度を制限することができる。
【００５８】
なお、上記第１・第２・第３・第４実施例において、可動部材３１の鉤部３５への凸部３８，３８Ａ〜３８Ｄの有無は任意である。弾発力変化機構と凸部３８，３８Ａ〜３８Ｄの両方を備えることにより、鏡１の上縁に鉤部３５を当接する衝撃は一層弱くなる。
【００５９】
また、鉤部３５に凸部３８，３８Ａ〜３８Ｄを備えた構成の鏡止め具１０は、弾発力変化機構を備えない構成でもよい。例えば、上記図１６に示す第４実施例の構成において、表面に被膜を施さないばね４１を用いることができる。この場合には、鏡１の上縁へ衝撃を与えないように凸部３８，３８Ａ〜３８Ｄが作用し、可動部材３１が持上がらないように、ばね４１の第１下降作用部４４，４４の弾発力が作用する。
【００６０】
【発明の効果】
本発明は上述のとおり構成されているので、次に記載する効果を奏する。
請求項１記載の発明は、ばねの弾発力を変化させる弾発力変化機構を設けたことにより、ばねの弾発力が変化するので、鉤部が下降する際の速度を制限することができる。このため、鏡の上縁に鉤部を当接した瞬間の鏡への衝撃を弱めることができる。従って、壁面に鏡を取付ける際に、鏡の上縁に衝撃を与えないように注意を払う必要がなく、取付け作業性が高まる。
しかも、ばねの弾発力を変化させることができるので、可動部材の持上がりに対する弾発力を大きく設定することができる。このため、可動部材がわずかな外力で持上がる恐れがなく、鏡の上縁を確実に止めることができる。
【００６１】
さらに請求項１記載の発明は、略逆Ｖ字状のばねの両端側を固定部材の左右側に有するばね受部に掛け、且つばねの中央側を可動部材の左右方向中央に有するばね掛け部に掛け、更に、ばねの両端側に、下方へ略ハ字形に開かれた第１下降作用部と、この第１下降作用部の上部で第１下降作用部よりも略ハ字形の開き角が大きい第２下降作用部とを形成し、弾発力変化機構を第１・第２下降作用部とばね掛け部とばね受部とで構成したことにより、第２下降作用部の方が第１下降作用部よりも開き角が大きいので、下方への弾発力も大きくなる。
そして、可動部材を下降させた場合に、ばねは最初に弾発力の小さな第１下降作用部がばね受部と係合しながら下降し、次に弾発力の大きな第２下降作用部がばね受部と係合しながら下降する。このため、鉤部は最初の所定時間に比較的低速で下降し、次にこれよりも高速で下降して鏡の上縁に当接する。従って、鉤部が高速で下降しても加速時間が短いので、鏡の上縁に当接する瞬間の最終速度は比較的低速ですむ。これにより、鉤部が鏡の上縁に当接した瞬間の衝撃を弱めることができる。従って、壁に鏡を取付ける際に、鏡の上縁に衝撃を与えないように注意を払う必要がなく、取付け作業性が高まる。
また、鏡が鏡止め具で壁面に取付けられた状態では、弾発力の大きな第２下降作用部がばね受部と係合しているので、可動部材の持上がりに対する弾発力が大きい。このため、可動部材がわずかな外力で持上がる恐れはなく、鏡の上縁を確実に止めることができる。
更に、ばねに第１・第２作用部を形成しただけの簡単な構成で、ばねの弾発力を変化させることができる。
【００６２】
請求項２記載の発明は、ばねの両端側に且つ第２下降作用部の上部に、ばねの左右方向外側に突出した円弧状の第３下降作用部を形成したので、鏡の上縁に当接する瞬間の最終速度を一層低速にすることができる。このため、鏡の上縁に鉤部を当接した瞬間の鏡への衝撃を一層弱めることができる。
【００６４】
請求項３記載の発明は、ばねの弾発力を変化させる弾発力変化機構を設けたことにより、ばねの弾発力が変化するので、鉤部が下降する際の速度を制限することができる。このため、鏡の上縁に鉤部を当接した瞬間の鏡への衝撃を弱めることができる。従って、壁面に鏡を取付ける際に、鏡の上縁に衝撃を与えないように注意を払う必要がなく、取付け作業性が高まる。
しかも、ばねの弾発力を変化させることができるので、可動部材の持上がりに対する弾発力を大きく設定することができる。このため、可動部材がわずかな外力で持上がる恐れがなく、鏡の上縁を確実に止めることができる。
さらに請求項３記載の発明は、弾発力変化機構を、表面に所定の摩擦抵抗を有する被膜を施されたばねの下降作用部とばね受部とで構成したことにより、下降作用部とばね受部との摩擦力によって、ばねの弾発力を変化させることができるので、ばねがシンプルな形状であるにもかかわらず、鉤部が下降する際の速度を制限することができる。また、可動部材の持上がりに対しても、ばねとばね掛け部との摩擦力が作用するので、可動部材の持上がりに対する抵抗力が一層大きくなる。

BACKGROUND OF THE INVENTION
The present invention relates to a mirror stopper for attaching a mirror to a wall surface.
[0002]
[Prior art]
Generally, a mirror is attached to a wall surface by a lower receiving member and an upper mirror holding member, and the mirror fixing member can be slid up and down with respect to the mirror (the wall surface is set with a set screw through a long hole provided in the mirror fixing member. The mirror stopper is slid in the range of the long hole by loosening this set screw.
However, with the above conventional technology, there is no problem at the beginning of installation, but if the mirror surface is repeatedly wiped with a rag during long-term use, the set screw will loosen and the mirror stopper will be easy to move, and a slight external force (the mirror surface will be moved up and down with the rag). There is a risk that it may be lifted by wiping. The mirror stopper gradually moves away from the upper edge of the mirror and becomes unsightly.
[0003]
In order to solve this problem, there is a technique disclosed in Japanese Utility Model Laid-Open No. 3-129361 (mirror fixing tool). According to FIG. 1 of this publication, the hook member (corresponding to the mirror stopper) 10 is provided above. The mirror locking portion 10a is formed and the biasing member fixing portion 12 is formed on the lower side. The hook member 10 is loosely fixed to the wall surface with the screw 3 through the long hole 11 provided in the mirror locking portion 10a. The hook member 10 is moved downward by engaging the ring 23 at one end of the biasing member (torsion spring) 20 and inserting the other end of the biasing member 20 for movement prevention into the biasing member fixing portion 12 of the hook member 10. It is a bullet.
The procedure for attaching the mirror M to the wall surface W with the mirror fixture was as follows: (1) The hook member 10 was picked and lifted, (2) The mirror M was set on the wall surface W, and (3) was picked. Release the hand (the hook member 10 is lowered by the elastic force of the movement preventing biasing member 20 and is locked to the upper edge of the mirror M).
[0004]
[Problems to be solved by the invention]
In such a mirror fixing tool, in order to prevent the hook member 10 from being lifted by a slight external force, the elastic force of the movement preventing urging member 20 for causing the hook member 10 to spring downward is large. Is required.
On the other hand, in order to attach the mirror M to the wall surface W, the hook member 10 that is lifted is locked to the upper edge of the mirror, and when the hand that has been picked is released, the hook member 10 is moved to the urging member 20 for preventing movement. It hits the upper edge of the mirror M vigorously with its elasticity. For this reason, since the edge of the mirror M may be lost if the impact hit is large, it is preferable that the elastic force of the movement preventing urging member 20 is not too large. However, in order to prevent the lifting, the elastic force of the movement preventing urging member 20 cannot be reduced.
In order to compensate for this, it is necessary to pay attention such as slowly lowering the upper edge of the mirror M so as not to give an impact to the hook member 10 during the hooking operation, which is troublesome.
[0005]
Therefore, the objects of the present invention are: (1) When attaching a mirror to the wall, it is not necessary to pay attention so as not to give an impact to the edge of the mirror; (2) The movable member may be lifted by a slight external force. The upper edge of the mirror can be surely stopped.
[0006]
[Means for Solving the Problems]
  In order to achieve the above object, the invention according to claim 1 is characterized in that a fixed member screwed to a wall surface and provided with a spring receiving portion and a vertical guide groove on the front surface and a guide capable of only moving up and down by the vertical guide groove. And a movable member having a spring hooking portion erected on the front surface, a hook portion provided on an upper portion of the movable member and engaged with an upper edge of a mirror, and the spring receiving portion and the spring hooking portion. In the mirror stopper comprising a spring that springs downward the movable member that is fitted to the fixed member so as to allow only a vertical movement, a spring force changing mechanism that changes the spring force of the spring.ProvidedIt is characterized by that.
  Since the spring force of the spring changes, the speed at which the buttocks descend can be limited. For this reason, the impact on the mirror at the moment when the buttocks abut on the upper edge of the mirror can be weakened.
  Moreover, since the spring force of the spring can be changed, the spring force with respect to the lifting of the movable member can be set large. For this reason, there is no possibility that the movable member will be lifted by a slight external force.
[0007]
  Further claim 1In the described invention, the spring is formed in a substantially inverted V-shape that is symmetrical with a wire or a strip, and is hung on the spring receiving portion having both ends of the spring on the left and right sides of the fixing member, and the center side is the The movable member is hung on the spring hanging portion at the center in the left-right direction, and further, on both end sides of the spring, a first lowering action portion opened downward in a substantially C shape, and an upper portion of the first lowering action portion And forming a second lowering action part having a substantially C-shaped opening angle larger than that of the first lowering action part, so that it opens to the left and right sides when the collar part is in a lower position that engages with the upper edge of the mirror. In addition, when the collar portion is at an upper position away from the upper edge of the mirror, it is configured to be narrowed to the center in the left-right direction by engagement with the spring receiving portion, and the elastic force change mechanism is configured to move the first and second lowering It is characterized by comprising an action part and the spring receiving part.
  Since the opening angle of the second lowering action part is larger than that of the first lowering action part, the downward elasticity is also large.
  When the movable member is lowered, the spring is first lowered while the first lowering action portion having a small elastic force is engaged with the spring receiving portion, and then the second lowering action portion having a larger elastic force is received by the spring support. Lowers while engaging the part. For this reason, the heel part descends at a relatively low speed for the first predetermined time, and then descends at a higher speed than this to contact the upper edge of the mirror. Therefore, since the acceleration time is short even if the heel part descends at a high speed, the final speed at the moment of contact with the upper edge of the mirror is relatively low. Thereby, the impact at the moment when the buttocks contact the upper edge of the mirror is weakened.
  Further, in a state where the mirror is attached to the wall surface with the mirror stopper, the second lowering action portion having a large elastic force is engaged with the spring receiving portion, so that the elastic force against the lifting of the movable member is large. For this reason, there is no possibility that the movable member is lifted by a slight external force.
[0008]
  Claim 2The described invention is characterized in that an arc-shaped third lowering action part protruding outward in the left-right direction of the spring is formed on both ends of the spring and on the upper part of the second lowering action part.
  Since the arc-shaped third action portion is formed on the spring, the final speed at the moment of contact with the upper edge of the mirror is further reduced. For this reason, the impact on the mirror at the moment when the buttocks contact the upper edge of the mirror is further reduced.
[0010]
  According to a third aspect of the present invention, there is provided a fixing member screwed to the wall surface and provided with a spring receiving portion and a vertical guide groove on the front surface, and guided by the vertical guide groove so that only vertical movement is possible. Is mounted on the movable member, and is attached to the upper part of the movable member, hooked to the upper edge of the mirror, hooked to the spring receiving portion and the spring hook portion, and moved vertically to the fixed member. In a mirror stopper composed of a spring that springs down a movable member that is fitted so as to be capable of being moved, a spring force changing mechanism that changes the spring force of the spring is provided.Provided,
  The spring is formed into a substantially inverted V-shape that is symmetrical with a wire or a strip, and both ends of the spring are hung on the spring receiving portion having the left and right sides of the fixed member, and the center side is the left-right direction of the movable member The hook is hooked on the upper edge of the mirror by forming a lowering action portion that is opened in a substantially C shape downward on both ends. When it is in the lower position, it opens to the left and right sides, and when the collar is in the upper position away from the upper edge of the mirror, it is configured to squeeze to the center in the left-right direction by engaging with the spring receiving part, A coating having a predetermined frictional resistance is applied to the spring, and the elastic force change mechanism is configured by a lowering action portion of the spring and the spring receiving portion on which the coating is applied.
  The spring's spring force can be changed by the frictional force between the lowering action part of the spring and the spring receiving part coated with a coating having a predetermined friction resistance on the surface, so that the spring has a simple shape. First, the speed at which the buttocks descend can be limited. Further, since the frictional force between the spring and the spring hooking portion acts on the lifting of the movable member, the resistance force against the lifting of the movable member is further increased.
[0014]

In the state (a), since the first lowering action portions 44 and 44 are engaged with the spring receiving portions 14 and 14, the spring 41 is narrowed to the center in the left-right direction.
In this state, the central portion 42 expands by its own elastic force, and the first lowering action portions 44 and 44 move outward along the spring receiving portions 14 and 14 by the horizontal component force at this time. For this reason, the spring 41 is lowered, but is relatively low speed because the downward elastic force is small.
[0030]
As shown in (b), the spring 41 is shifted to the engagement from the first lowering action parts 44, 44 to the second lowering action parts 45, 45 with respect to the spring receiving parts 14, 14. Since the second lowering action parts 45, 45 have a larger opening angle than the first lowering action parts 44, 44, the horizontal component force is also large, and the downward elastic force is large. For this reason, the second lowering action portions 45, 45 rapidly move outward along the spring receiving portions 14, 14. Therefore, although the spring 41 continues to descend, the spring 41 is relatively fast because of its large downward force.
[0031]
Thereafter, as shown in (c), the spring 41 shifts to the engagement of the upper portions of the second lowering action portions 45, 45 with respect to the spring receiving portions 14, 14, and stops the lowering.
Thus, the elastic force of the spring 41 is such that when the second lowering action portions 45, 45 are engaged with the spring receiving portions 14, 14, the first lowering action portions 44, 44 are the spring receiving portions. It changes so that it may become larger than the state engaged with 14,14.
[0032]
Next, an assembling procedure of the mounting structure of the mirror 1 by the lower receiver 4 and the mirror stopper 10 having the above-described configuration will be described.
First, as shown in FIG. 1, the lower receptacle 4 is attached to the wall surface 2, and then the mirror stopper 10 is aligned with the wall surface 2 and attached.
Next, a procedure for attaching the mirror stopper 10 will be described. 6 and 7 are explanatory views of the operation of the mirror stopper (first embodiment) according to the present invention.
[0033]
As shown in FIG. 6, the mirror stopper 10 inserts the leg portions 33, 33 of the movable member 31 into the longitudinal guide grooves 13, 13 of the fixed member 11, and then connects the central portion 42 of the spring 41 to the spring hook portion 36. After that, the both ends of the spring 41 (upper part of the second lowering action part 45) are hung on the spring receiving part 14 while compressing both ends of the spring 41. The assembled mirror stopper 10 is attached to the wall surface 2 with a set screw 21 (see FIG. 3).
[0034]
Thereafter, when the collar portion 35 of the movable member 31 is picked and lifted, the movable member 31 rises to the upper position shown in FIG. At the same time, both end sides of the spring 41 move inward along the spring receiving portions 14 and 14. In this upper position, the movable member 31 is locked by a frictional force generated by the holding portion 17 and the pressure contact portion 34 being in pressure contact with each other, and does not descend even if the hand that has been picked is released.
[0035]
After the upper edge of the mirror 1 is aligned, when the collar portion 35 of the movable member 31 is pushed down, the holding portion 17 and the leg portions 33 and 33 are elastically deformed in directions opposite to each other. For this reason, the holding part 17 and the press contact part 34 are unlocked by a frictional force. Accordingly, the movable member 31 is pulled down by the elastic force of the spring 41.
That is, as shown in FIG. 6, the central portion 42 of the spring 41 expands by its own elastic force, and both end sides move outward along the spring receiving portions 14 and 14 by the horizontal component force at this time. For this reason, the spring 41 pulls down the movable member 31. Accordingly, the movable member 31 is automatically pulled down, and the collar portion 35 is locked to the upper edge of the mirror 1.
This completes the assembly work.
[0036]
By the way, when the movable member 31 is lowered from the state shown in FIG. 7, the collar portion 35 is first lowered for a predetermined time (time when the first lowering action portions 44 and 44 are lowered along the spring receiving portions 14 and 14). At a relatively low speed, and then at a relatively high speed for the next predetermined time (the time during which the second lowering action portions 45, 45 are lowered along the spring receiving portions 14, 14). Abuts the upper edge of
For this reason, since the acceleration time is short even when the collar portion 35 descends at a high speed, the final speed at the moment when it comes into contact with the upper edge of the mirror 1 can be relatively low. Therefore, the impact on the mirror 1 at the moment when the collar portion 35 abuts on the upper edge of the mirror 1 is weak.
[0037]
Thus, since the impact on the mirror 1 is weak, it is not necessary to pay attention not to give an impact to the upper edge of the mirror 1 when attaching the mirror to the wall 1.
Moreover, since the spring force of the spring 41 can be changed, the spring force (resistance force) against the lifting of the movable member 31 can be set large. That is, in the state where the mirror 1 shown in FIG. 6 is attached to the wall surface 2 with the mirror stopper 10, the second lowering action portions 45, 45 having a large elastic force are engaged with the spring receiving portions 14, 14. The resilience against the lifting of the movable member 31 is large. For this reason, there is no fear that the movable member 31 is lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped.
[0038]
On the other hand, as shown in FIG. 4A, when the collar portion 35 is lowered by the spring force of the spring from the state in which the collar portion 35 is disengaged from the upper edge of the mirror 1, the convex portion 38 becomes the mirror 1 as shown in FIG. It hits the upper end face 1a. For this reason, the collar part 35 does not collide with the corner | angular parts 1b and 1c of the upper edge of the mirror 1. FIG. Therefore, when attaching the mirror 1 to the wall surface, it is not necessary to pay attention not to give an impact to the corners 1b and 1c on the upper edge of the mirror 1.
Moreover, since the convex part 38 is contact | abutted to the rear part from the approximate center of the thickness direction of the upper end surface 1a of the mirror 1 or the center, it can further prevent that the impact is applied to the corner | angular part 1b of the front side of the mirror 1. FIG.
[0039]
Next, modified examples of the convex portion 38 provided on the flange portion 35 of the movable member 31 will be described with reference to FIGS.

It consists of a cushioning material having elasticity. The convex portion 38C is fixed to the flange portion 35 by pasting or the like.
[0042]

The convex portions 38C and 38D shown in FIGS. 10 and 11 may be fixed to the upper end surface 1a of the mirror 1 by pasting or the like.
[0043]
Next, a second embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same structure as the said 1st Example, and the description is abbreviate | omitted.
12 (a) and 12 (b) are configuration diagrams of a mirror stopper (second embodiment) according to the present invention, (a) is a front view of the mirror stopper, and (b) is a front view of a spring. .
In the second embodiment, arc-shaped third lowering action portions 46 and 46 projecting outward in the left-right direction of the spring 41 are integrally formed on both ends of the spring 41 and on the upper portions of the second lowering action portions 45 and 45. It is characterized by that.
The configuration including the spring receiving portion 14, the spring hook portion 36, and the first, second, and third descending action portions 44, 45, 46 constitutes a resilience changing mechanism that changes the resilience of the spring 41. To do.
[0044]
Next, the operation of the second embodiment will be described with reference to FIGS.
FIG. 13 is an operation explanatory view of the mirror stopper (second embodiment) according to the present invention.
When the collar portion 35 of the movable member 31 is raised to the upper position shown in FIG. 13, when the collar portion 35 is pushed down after the upper edge of the mirror 1 is aligned, the holding portion 17 and the press contact portion 34 are locked by frictional force. Comes off. Accordingly, the movable member 31 is pulled down by the elastic force of the spring 41, and the collar portion 35 is locked to the upper edge of the mirror 1 as shown in FIG.
[0045]
In this case, the engagement relationship of the spring 41 moves with respect to the spring receiving portions 14 and 14 in the order of the first lowering action portions 44 and 44 → the second lowering action portions 45 and 45 → the third lowering action portions 46 and 46. Finally, the lower end of the central portion 42 is engaged.
For this reason, the second lowering action portions 45, 45 of the spring 41 are rapidly lowered along the spring receiving portions 14, 14, but thereafter, the arc-shaped third lowering action portions 46, 46 protruding outward are spring-loaded. Since it engages with the parts 14 and 14, the descending speed again becomes low. Accordingly, the final speed at which the flange 35 abuts against the upper edge of the mirror 1 can be relatively low. And the impact which contact | abuts the collar part 35 on the upper edge of the mirror 1 becomes still weaker.
[0046]
Therefore, when attaching the mirror 1 to the wall surface 2, it is not necessary to pay attention not to give an impact to the upper edge of the mirror 1.
Moreover, the arcuate projection height of the third lowering action portions 46 and 46 can be set large, and the resilience (resistance force) against the lifting of the movable member 31 can be set large. For this reason, there is no fear that the movable member 31 will be lifted by a slight external force, and the upper edge of the mirror 1 can be stopped more reliably.
[0047]
Next, a third embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same structure as the said 1st Example, and the description is abbreviate | omitted.
FIGS. 14A and 14B are configuration diagrams of a mirror stopper (third embodiment) according to the present invention, in which FIG. 14A shows a front view and FIG. 14B shows a side view.
In the third embodiment, the end portions 43 and 43 at the lowermost ends and the first lowering action portions (lowering action portions) 44 and 44 on the upper ends of the end portions 43 and 43 are provided at both ends of the spring 41 that is curved in a side view. Only formed.
[0048]
Specifically, the spring 41 has first lowering action portions 44, 44 extending from both lower ends of the central portion 42 to the upper portions of the terminal portions 43, 43, and the first lowering action portions 44, 44 are curved in the left-right direction ( (Curled) shape.
Further, as shown by the imaginary line of (b), the spring 41 is curved in a side view curved to the front side (left side in this figure) (from the upper end of the central portion 42 to the lower end of the first lowering action portion 44, and gently bent). Shape).
[0049]
The spring 41 is squeezed rearward (right side in this figure) by the lowering action portion 44 being hooked on the L-shaped spring receiving portion 14 in plan view, and is slightly flat as shown by the solid line in FIG. It is set in a deformed state.
The configuration including the spring receiving portions 14 and 14 and the first lowering action portions 44 and 44 combined in this manner constitutes a resilience changing mechanism that changes the resilience of the spring 41.
[0050]
Next, the operation of the third embodiment will be described with reference to FIGS.
FIGS. 15 (a) and 15 (b) are diagrams for explaining the operation of the mirror stopper (third embodiment) according to the present invention, wherein (a) shows the front and (b) shows the side.
When the collar 35 of the movable member 31 is raised to the upper position shown in FIG. 15A and the upper edge of the mirror 1 is aligned and then the collar 35 is pushed down, the holding part 17 and the pressure contact part 34 are in friction. Unlock by force. Accordingly, the movable member 31 is pulled down by the elastic force of the spring 41, and the collar portion 35 is locked to the upper edge of the mirror 1 as shown in FIG.
[0051]
In this case, as shown in FIG. 15B, the spring receiver 14 is engaged with the lower end of the first lowering action portion 44 in a state where the flange portion 35 is raised to the upper position. For this reason, since the spring 41 is not squeezed by the spring receiving portion 14, it is generally curved in a side view. From this state, the central portion 42 expands in the left-right direction in FIG. 15A by its own elastic force, and the first descending action portions 44 and 44 move along the spring receiving portions 14 and 14 by the horizontal component force at this time. Move outward. For this reason, the spring 41 descends.
[0052]
As the first lowering action part 44 is lowered, the first lowering action part 44 is squeezed by the spring receiving part 14 from the lower part to the upper part, so that the first lowering action part 44 is lowered while being deformed in a flat shape in side view. For this reason, since the spring 41 is lowered with the lowering speed limited, the impact of the collar portion 35 coming into contact with the upper edge of the mirror 1 can be weakened. Therefore, when attaching the mirror 1 to the wall surface 2, it is not necessary to pay attention so as not to give an impact to the upper edge of the mirror 1.
[0053]
Further, in the state where the mirror 1 is attached to the wall surface 2 with the mirror stopper 10, the portion of the first lowering action portion 44 engaged with the spring receiving portion 14 is deformed in a flat shape in a side view. The resilience (resistance) to the lifting of the is large. For this reason, there is no fear that the movable member 31 is lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped.
According to the third embodiment, the resilient force of the spring 41 can be changed with a simple configuration in which the spring 41 is curved in a side view.
[0054]
Next, a fourth embodiment will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected about the same structure as the said 3rd Example, and the description is abbreviate | omitted.
FIG. 16 is a front view of a mirror stopper (fourth embodiment) according to the present invention.
In the fourth embodiment, the spring 41 of the third embodiment shown in FIG. That is, the spring 41 is configured not to be curved in a side view. The spring 41 is characterized in that a film having a predetermined frictional resistance is applied to the surface, and the film is applied by, for example, plating or resin coating.
The configuration including the spring receiving portions 14 and 14 and the first lowering action portions 44 and 44 combined in this manner constitutes a resilience changing mechanism that changes the resilience of the spring 41.
[0055]
Next, the operation of the fourth embodiment will be described with reference to FIGS.
FIG. 17 is an operation explanatory view of a mirror stopper (third embodiment) according to the present invention.
When the collar portion 35 of the movable member 31 is raised to the upper position shown in FIG. 17 and the collar portion 35 is pushed down after the upper edge of the mirror 1 is aligned, the holding portion 17 and the press contact portion 34 are caused by frictional force. The lock is released. Accordingly, the movable member 31 is pulled down by the spring force of the spring 41, and the collar portion 35 is locked to the upper edge of the mirror 1 as shown in FIG.
[0056]
In this case, since the surface of the spring 41 is coated with a frictional resistance, the sliding frictional resistance with the spring receiving portions 14 and 14 is large. For this reason, when the movable member 31 is lowered, the collar portion 35 is lowered at a relatively low speed and comes into contact with the upper edge of the mirror 1. Accordingly, the final speed at which the flange 35 abuts against the upper edge of the mirror 1 can be relatively low. And the impact which contact | abuts the collar part 35 on the upper edge of the mirror 1 becomes still weaker.
[0057]
Thus, when attaching the mirror 1 to the wall surface 2, it is not necessary to pay attention not to give an impact to the upper edge of the mirror 1. In addition, since the frictional force between the spring 41 and the spring receiving portions 14 and 14 acts on the lifting of the movable member 31, the resilience (resistance force) against the lifting of the movable member 31 is further increased. For this reason, there is no fear that the movable member 31 is lifted by a slight external force, and the upper edge of the mirror 1 can be reliably stopped.
According to the fourth embodiment, although the spring 41 has a simple shape, it is possible to limit the speed at which the collar portion 35 descends.
[0058]
In the first, second, third, and fourth embodiments, the presence or absence of the convex portions 38, 38A to 38D on the flange portion 35 of the movable member 31 is arbitrary. By providing both the elastic force change mechanism and the convex portions 38, 38 </ b> A to 38 </ b> D, the impact of contacting the flange portion 35 with the upper edge of the mirror 1 is further reduced.
[0059]
Further, the mirror stopper 10 having the configuration including the convex portions 38 and 38A to 38D on the collar portion 35 may be configured not to include the elastic force change mechanism. For example, in the configuration of the fourth embodiment shown in FIG. 16, a spring 41 that does not coat the surface can be used. In this case, the convex portions 38, 38A to 38D act so as not to give an impact to the upper edge of the mirror 1, and the first lowering action portions 44, 44 of the spring 41 prevent the movable member 31 from lifting. Elasticity acts.
[0060]
【The invention's effect】
  Since this invention is comprised as mentioned above, there exists an effect described below.
  According to the first aspect of the present invention, there is provided an elastic force changing mechanism for changing the elastic force of the spring.ProvidedAs a result, since the spring force of the spring changes, the speed at which the buttocks descend can be limited. For this reason, the impact on the mirror at the moment when the buttocks abut on the upper edge of the mirror can be weakened. Therefore, when attaching the mirror to the wall surface, it is not necessary to pay attention so as not to give an impact to the upper edge of the mirror, and the mounting workability is improved.
  Moreover, since the spring force of the spring can be changed, the spring force with respect to the lifting of the movable member can be set large. For this reason, there is no fear that the movable member is lifted by a slight external force, and the upper edge of the mirror can be reliably stopped.
[0061]
  Further claim 1The invention described is hung on a spring receiving portion having both ends of a substantially inverted V-shaped spring on the left and right sides of the fixed member, and on the spring holding portion having the center side of the spring at the center in the left and right direction of the movable member, The first lowering action part opened in a substantially C shape downward on both ends of the spring, and the second lowering having a substantially C-shaped opening angle larger than that of the first lowering action part above the first lowering action part And the elastic force change mechanism is constituted by the first and second lowering action parts, the spring hooking part, and the spring receiving part, so that the second lowering action part is more than the first lowering action part. Since the opening angle is large, the downward elasticity is also increased.
  When the movable member is lowered, the spring is first lowered while the first lowering action portion having a small elastic force is engaged with the spring receiving portion, and then the second lowering action portion having a large elastic force is provided. It descends while engaging with the spring receiving part. For this reason, the heel part descends at a relatively low speed for the first predetermined time, and then descends at a higher speed than this to contact the upper edge of the mirror. Therefore, since the acceleration time is short even if the heel part descends at a high speed, the final speed at the moment of contact with the upper edge of the mirror is relatively low. Thereby, the impact at the moment when the buttocks contact the upper edge of the mirror can be weakened. Therefore, when attaching the mirror to the wall, it is not necessary to pay attention so as not to give an impact to the upper edge of the mirror, and the mounting workability is improved.
  Further, in a state where the mirror is attached to the wall surface with the mirror stopper, the second lowering action portion having a large elastic force is engaged with the spring receiving portion, so that the elastic force against the lifting of the movable member is large. For this reason, there is no fear that the movable member is lifted by a slight external force, and the upper edge of the mirror can be reliably stopped.
  Furthermore, the spring force of the spring can be changed with a simple configuration in which the first and second action portions are formed on the spring.
[0062]
  Claim 2In the described invention, the arc-shaped third lowering action portion projecting outward in the left-right direction of the spring is formed on both ends of the spring and on the upper part of the second lowering action portion. The final speed can be further reduced. For this reason, it is possible to further weaken the impact on the mirror at the moment when the collar comes into contact with the upper edge of the mirror.
[0064]
  According to a third aspect of the present invention, there is provided an elastic force changing mechanism for changing an elastic force of the spring.ProvidedAs a result, since the spring force of the spring changes, the speed at which the buttocks descend can be limited. For this reason, the impact on the mirror at the moment when the buttocks abut on the upper edge of the mirror can be weakened. Therefore, when attaching the mirror to the wall surface, it is not necessary to pay attention so as not to give an impact to the upper edge of the mirror, and the mounting workability is improved.
  Moreover, since the spring force of the spring can be changed, the spring force with respect to the lifting of the movable member can be set large. For this reason, there is no fear that the movable member is lifted by a slight external force, and the upper edge of the mirror can be reliably stopped.
  Furthermore, the invention according to claim 3 is configured such that the elastic force change mechanism is composed of a lowering action part and a spring receiving part of a spring whose surface has a coating having a predetermined frictional resistance. The spring force of the spring can be changed by the frictional force with the part, so that the speed when the collar part descends can be limited even though the spring has a simple shape. Further, since the frictional force between the spring and the spring hooking portion acts on the lifting of the movable member, the resistance force against the lifting of the movable member is further increased.
