本発明は、被取付面に取り付けて被掛物を掛ける掛け具に関する。
【０００２】
【従来の技術】
従来から壁面等の被取付面に取り付けて小物等の被掛物を掛ける掛け具として種々形態のものが提供されており、例えば、図１０に示す如く、可撓弾性を有するゴムや合成樹脂等から成形された吸盤体５０と、該吸盤体５０の背面に突設された連結杆５１と、該連結杆５１が遊貫挿されて吸盤体５０の背面側に配設された押圧体５２と、該押圧体５２の背面側に突出した前記連結杆５１に軸線を直交させて取り付けられる軸体５３と、被掛物を吊り下げ可能に形状設定され、前記軸体５３を介して連結杆５１に回転可能に連結されたフック体５４とで構成されたものが知られている。
【０００３】
前記押圧体５２は、剛性を有しており、吸盤体５０は覆うことができるように外径が設定されており、吸盤体５０と対向する面の周縁部に環状凸部５５が形成されている。前記フック体５４は、押圧体５２を押圧可能に連結杆５１に連結される押圧部５６と、該押圧部５６の一端に連設され、被掛物が掛けられるフック部５７とで構成されている。
【０００４】
前記押圧部５６は、他端側が前記軸体５３周りで回転する変心カム状に形成され、これにより、連結杆５１の軸線方向に位置して起立状態にあるフック部５７を傾伏状態にするように、フック体５４を回転させることで、押圧体５２の背面を摺動して徐々に押圧する凸状の湾曲面５８を備えている。また、該押圧部５６は、前記湾曲面５８の湾曲方向一端に接続され、フック部５７が傾伏状態となった際に、押圧部５６の背面に略平行に対向する平部５９を備えており、該平部５９と前記湾曲面５８との接続部分に係止用凸部６０が形成されている。これにより、軸体５３と押圧体５２に対する押圧部５６の押圧位置との相対位置関係により、スナップアクションを伴って押圧部５６の回転を規制し、フック体５４が傾伏状態で維持されるように構成されている。
【０００５】
上記構成の掛け具は、吸盤体５０を被取付面Ｗに押し付けた状態で、図１１に示す如く、軸体５３を支点にしてフック体５４を傾伏状態にすることで、押圧部５６の作用により押圧体５２と軸体５３とを相対的に離間させ、環状凸部５５が吸盤体５０にめり込むように押圧体５２で吸盤体５０の背面周縁部を押圧し、環状凸部５５のめり込んだ部分に押圧力を集中させて吸盤体５０の周縁部からの空気の流入を確実に防止するとともに、軸体５２及び連結杆５１を介して吸盤体５０の中央部を押圧体５２側に弾性変形させ、被取付面Ｗと吸着盤１との間の負圧状態を高めて高い吸着能力を得るようにしている。（例えば、特許文献１参照）

【発明が解決しようとする課題】
しかしながら、上記構成の掛け具は、可撓弾性を有する吸盤体５０の背面周縁部を押圧する押圧体５２の内面に環状凸部５５が形成されているため、長期に亘って被取付面に取り付けたままにしたり、着脱を繰り返したりすると、吸盤体５０に環状凸部５５のめり込んだ型が残ってしまうことがある。
【０００８】
そうすると、掛け具を取り外して再度被取付面に取り付ける際には、押圧体５２が吸盤体５０の背面周縁部を押圧しても、環状凸部５５は残った型内に入り込んだだけの状態となり、新品の時のように押圧体５２の押圧力を集中的に吸盤体５０に作用させることができず、吸盤体５０の外周からの空気の流入防止作用を発揮させることができない場合があった。そのため、吸盤体５０の外周縁部から経時的に空気が流入し、被取付面から脱落することがあった。
【０００９】
また、該掛け具は、上述の如く、押圧部５６を連結杆５１に軸着する軸体５３と、押圧部５６の押圧体５２に対する押圧位置との相対位置関係により、押圧部５６の回転を規制してフック体５４の倒伏状態を維持し、押圧体５２による吸盤体５０の外周縁部に対する押圧状態、及び吸盤体５０の強制的な引動状態を維持させるように構成されているため、軸体５３周りで回転させる荷重がフック体５４に作用すると、フック体５４の傾伏状態が解除されてしまう場合がある。
【００１０】
そうすると、押圧体５２による吸盤体５０の外周縁部に対する押圧状態が解除されるとともに、吸盤体５０の強制的な引動状態が解除され、被取付面Ｗと吸盤体５０との間の負圧状態を維持することができずに、掛け具が被取付面から脱落する場合があった。
【００１１】
そこで、本発明は、斯かる実情に鑑み、取り付け状態で放置したり、被取付面に対する着脱を繰り返し行ったりしても、被取付面と吸盤体との間に空気が流入するのを確実に防止することができる掛け具を提供することを第一の課題とし、被掛物を掛けるフック体の起伏状態に関係なく、被取付面に対する吸盤体の吸着状態を維持することができる掛け具を提供することを第二の課題とする。
【００１２】
【課題を解決するための手段】
本発明にかかる掛け具は、上記第一の課題を解決すべくなされたものであり、請求項１記載の如く、可撓弾性を有する吸盤体と、該吸盤体の背面に突設された連結杆と、該連結杆が遊貫挿された押圧体と、該押圧体の背面側に突出した前記連結杆に連結され、被掛物が掛けられるフック体とを備えてなり、押圧体及び連結杆を該連結杆の軸線方向、且つ離間方向に相対移動させることで、吸盤体の背面周縁部を押圧体で押圧し、且つ吸盤体を弾性変形させるように構成された掛け具であって、前記吸盤体は、前記背面周縁部に押圧体に向けて突出した環状凸部を備えてなることを特徴とする。
【００１３】
上記構成の掛け具によれば、吸盤体が背面周縁部に押圧体側に突出した環状凸部を備えているので、押圧体で吸盤体の背面周縁部を押圧した際に、環状凸部は押し潰された態様となる。そうすると、環状凸部の形成された部分に押圧力が集中し、この部分が被取付面に対して他の部分よりも密接な状態となり、被取付面と吸盤体との間への気体の流入を確実に防止することができ、吸着体の被取付面に対する吸着状態を長期に亘って維持することができる。
【００１４】
また、環状凸部は、吸盤体と同様に可撓弾性を有しているので、押圧体による押圧を解除すると、多少偏平した状態になる場合があるが、自己の弾性復元力により吸盤体の背面から突出した態様となる。したがって、長期に亘って押圧体に押圧された状態（取付状態）で放置されたり、該被取付面に対して着脱が繰り返し行われたりしても、再度被取付面に取り付ける際に、環状凸部の存在によって押圧力が集中して作用し、被取付面と吸盤体との間への気体の流入を確実に防止することができ、吸着体の被取付面に対する吸着状態を長期に亘って維持することができる。
【００１５】
さらに、請求項２記載の如く、前記押圧体には、前記環状凸部と凹凸嵌合する環状凹部が形成され、該環状凹部は環状凸部を押圧可能に構成されることが好ましい。このようにすれば、吸盤体が押圧体に押圧された際に、環状凸部は押圧状態で環状凹部に嵌め合わされ、環状凹部の内形状に即して弾性変形することになり、不均一に押し潰されるのを防止することができる。したがって、吸盤体の周縁部は、吸盤体の全周に亘って被取付面に均一な状態で密接し、安定した吸着を実現することができる。
【００１６】
請求項３記載の発明は、第二の課題を解決すべくなされたものであり、可撓弾性を有する吸盤体と、該吸盤体の背面に突設された連結杆と、該連結杆が遊貫挿された押圧体と、該押圧体の背面側に突出した前記連結杆に、軸線を直交させて連結された軸体と、該軸体回りで回転可能に設けられたフック体とを備えてなり、押圧体及び連結杆を該連結杆の軸線方向、且つ離間方向に相対移動させることで、吸盤体の背面周縁部を押圧体で押圧し、且つ吸盤体を弾性変形させるように構成された掛け具であって、フック体は、押圧体と軸体との間に介装される介装部と、該介装部に連設されて被掛物が掛けられるフック部とを備え、該介装部は、連結杆及び軸体の軸線に対して交差方向で押圧体と相対摺動する第一摺接部と、前記交差方向で軸体と相対摺動する軸摺接部と、前記交差方向の一方側で第一摺接部に連設されて押圧体と相対摺動する円弧状の第二摺接部と、前記交差方向の一方側で軸摺接部に隣接して形成され、軸体が第一摺接部側に向けて入り込む軸受凹部とを備え、第一摺接部と軸摺接部との連結杆の軸線方向の間隔が、前記交差方向の一方側に向けて拡大するように設定され、第二摺接部は曲率半径が略一定に設定され、軸受凹部は入り込んだ軸体の軸線が第二摺接部の曲率中心と略一致するように構成されてなることを特徴とする。
【００１７】
上記構成の掛け具によれば、フック体が押圧体と軸体との間に介装される介装部と、該介装部に連設されて被掛物が掛けられるフック部とを備え、第一摺接部と軸摺接部との連結杆の軸線方向の間隔が、前記交差方向の一方側に向けて拡大するように設定されているので、押圧体及び軸体に対して介装部（フック体）を前記交差方向の他方側に相対移動させると、押圧体及び軸体は、第一摺接部と軸摺接部との間隔の変化に伴って、間隔が押し広げられるように相対的に離間することになる。
【００１８】
そうすると、押圧体と軸体との相対移動に伴って、押圧体は、吸盤体の背面周縁部を押圧するとともに、軸体が取り付けられた連結杆が軸線方向に移動し、吸盤体が押圧体側に引動されて弾性変形することになる。なお、この状態において、吸盤体の弾性復元力により、軸体を押圧体側に引き寄せようとする引っ張り力が作用している。
【００１９】
そして、介装部は、前記交差方向の一方側で軸摺接部に隣接して形成されて軸体が第一摺接部側に向けて入り込む軸受凹部を備えているので、介装部をさらに前記交差方向の他方側に向けて移動させると、軸摺接部と相対摺動している軸体が前記引っ張り力により軸受凹部内に入り込み、介装部は、前記交差方向での移動がロックされた状態となり、フック部に被掛物を掛けることができるようになる。
【００２０】
そして、介装部は、前記交差方向の一方側で第一摺接部に連設されて押圧体と相対摺動する円弧状の第二摺接部を更に備え、第二摺接部は曲率半径が略一定に設定され、軸受凹部は入り込んだ軸体の軸線が第二摺接部の曲率中心と略一致するように構成されているので、フック体が軸体周りで回転しても、第二摺接部における押圧体に対する接触（押圧）位置から軸体の軸心までの距離が略一定であり、吸盤体に対する押圧体の押圧状態、及び吸盤体の弾性変形状態が一定に保たれることになる。これにより、被掛物を掛けるフック体（フック部）の起伏に関係なく、被取付面に対する吸盤体の吸着状態を維持することができる。
【００２１】
また、請求項４記載の如く、前記第一摺接部及び軸摺接部のそれぞれが、真っ直ぐな面で形成されることが好ましい。このようにすれば、介装部は前記第一摺接部と軸摺接部との間が楔状を呈することになり、フック体を介装部の一端側（フック部側）に円滑に移動させることができ、また、押圧体と軸体とを円滑に相対移動させることができる。
【００２２】
【発明の実施の形態】
以下、本発明の第一実施形態にかかる掛け具について、添付図面を参酌しつつ説明する。
【００２３】
本実施形態にかかる掛け具は、図１及び図２に示す如く、壁面等の被取付面Ｗに吸着させる吸盤体１と、該吸盤体１の背面に突設された棒状の連結杆２と、該連結杆２が遊貫挿されて該吸盤体１の背面側に配設された押圧体３と、小物や袋等の被掛物（図示しない）を掛けるフック体４と、該フック体４を連結杆２の先端部に連結する軸体５とで構成されている。
【００２４】
前記吸盤体１は、可撓弾性を有するゴムや合成樹脂等を平面視円形をなす皿状に成形したものであり、凹面が前記被取付面Ｗに当接させて吸着させる吸着面Ｓに設定され、凸面側が背面Ｒに設定されている。
【００２５】
該吸盤体１は、吸着面Ｓの略全面を被取付面Ｗに当接させることで、皿状に戻ろうとする自己弾性復元力によって、吸着面Ｓと被取付面Ｗとの間が負圧になって、被取付面Ｗに吸着できるようになってなっており、被取付面Ｗへの吸着面Ｓの当接のし易さ、及び自己弾性復元力を考慮して、平面視中央部から周縁部に向けて肉厚が漸減するように形成されている。また、吸盤体１の背面Ｒの周縁部（以下、背面周縁部という）には、押圧体３に向けて突出した環状凸部１０が形成されている。該環状凸部１０は、当該吸盤体１を成形する際に一体成形されたものであり、可撓弾性を有している。
【００２６】
前記連結杆２は、棒状の連結杆本体２０と、該連結杆本体２０の基端部に同心で連設された円板状の抜止部２１とで構成されている。前記連結杆本体２０は、先端部に前記軸体５を挿通する挿通穴２００が貫通して穿設されており、該抜止部２１は、連結杆本体２０が吸盤体１と同心となるように、吸盤体１の成型時において前記吸盤体１の平面視略中央部に埋設されている。これにより、連結杆２は、連結杆本体２０が吸盤体１の背面Ｒから突出した態様となっている。
【００２７】
前記押圧体３は、剛性を有した皿状の樹脂成形品であり、平面視中央部が円形平板状に形成されており、吸盤体１の背面Ｒを覆うことができるように外径が設定されている。また、該押圧体３は、平面視略中央部に前記連結杆２（連結杆本体２０）を遊挿する貫通穴３０が穿設されるとともに、外周縁部に平板環状部３１が形成されおり、吸盤体１の背面周縁部を押圧できるよう構成されている。
【００２８】
該押圧体３は、吸盤体１と対向する前記平板環状部３１の内面に吸盤体１の環状凸部１０が凹凸嵌合する環状凹部３２が形成されている。該環状凹部３２は、環状凸部１０の突出量よりもやや浅い深さに設定されており、押圧体３（平板環状部）で吸盤体１の背面周縁部を押圧した際に、環状凹部３２に嵌合した環状凸部１０が押圧されて変形するようになっている。
【００２９】
前記フック体４は、押圧体３と同様に、剛性を有する樹脂成型品であり、連結杆２に軸体５を介して連結され、押圧体３の背面を押圧する押圧部４１と、該押圧部４１の一端に連設され、被掛物を吊り下げ可能に形状設定されたフック部４２とで構成されている。
【００３０】
前記押圧部４１は、前記連結杆本体２０を介在させ得る間隔を有して対向する一対の押圧板４１０，４１０で構成されており、前記フック部４２は、一対の押圧板４１０，４１０の一端同士を連結するように連設されている。一対の押圧板４１０，４１０には、前記軸体５を挿通する貫通穴４１１が穿設されており、各押圧板４１０，４１０は、該貫通穴４１１の穴心を回転中心に設定された変心カム状に形成されている。
【００３１】
該押圧部４１は、変心カム状に形成されることで、フック体４が傾伏状態となるように、フック体４を軸体５周りで一方向に回転させた際に、押圧体３の背面を摺動して該押圧体３を徐々に押圧する凸状の湾曲面４１２が端面に形成されている。また、該押圧部４１は、前記湾曲面４１２の湾曲方向一端に接続され、フック体４が傾伏状態となった際に、押圧部４１の背面に略平行に対向する平部４１３を備えており、該平部４１３と前記湾曲面４１２との接続部分に係止用凸部４１４が形成されている。これにより、押圧体３に対する押圧部４１の押圧位置と軸体５との相対位置関係により、スナップアクションを伴って押圧部４１の回転を規制し、フック体４が傾伏状態で維持されるように構成されている。
【００３２】
前記軸体５は、連結杆２の挿通穴２００に挿通した状態で、両端部が連結杆２から突出するように構成されており、該両端部は、一対の押圧板４１０，４１０の貫通穴４１１，４１１に挿入できる外径に設定されている。なお、本実施形態にかかる軸体５は、一端から他端に向けて外径が漸減したテーパピン状に形成されており、連結杆２の挿通穴２００に挿入した際に、両端部が連結杆２から突出するとともに、挿通穴２００に圧入された状態となるように構成されている。
【００３３】
以上構成の掛け具を被取付面Ｗに取り付けるには、まず、押圧部４１（押圧板４１０，４１０）の湾曲面４１２の曲率半径が最小となる部分を押圧体３の背面に対向させるように、フック体４を起立状態にする。この状態で、押圧部４１は、押圧体３に圧接した状態になっておらず、押圧体３は、フック体４と吸盤体１との間で移動できる状態となっている。
【００３４】
そして、吸盤体１の吸着面Ｓが略全面に亘って被取付面Ｗに当接するように、吸盤体１を被取付面Ｗに押し付け、この状態で、図３に示す如く、フック体４を軸体５周りに回転させる。そうすると、上述の如く、フック体４の押圧部４１の湾曲面４１２の曲率半径の変化に伴って、押圧部４１が押圧体３の背面を押圧して押圧体３が吸盤体１に向けて押圧されるとともに、連結杆２が軸線方向に引動されて吸盤体１の略中央部が押圧体３側に引っ張られることになる。そうすると、吸盤体１の吸着面Ｓと被取付面Ｗとの間が負圧状態になり、吸盤体１が被取付面Ｗに吸着した状態となる。そして、係止用凸部４１４が押圧体３の背面を押圧して後に、平部４１３が押圧体３の背面と対向した状態になると押圧体３による吸盤体１に対する押圧、及び連結杆２の引導状態を維持したまま、押圧部４１における軸体５周りの回転が規制され、フック体４は、傾伏状態で維持することになる。
【００３５】
この状態で、図４に示す如く、吸盤体１の環状凸部１０は、押圧体３の環状凹部３２に嵌め合わされた態様となり、押圧体３による吸盤体１の押圧により、環状凸部１０が不均一に押し潰されることなく、環状凹部３２の形状に即して変形している。したがって、吸盤体１の周縁部における吸着面Ｓは、吸盤体１の周縁部の全周に亘って被取付面Ｗに均一な状態で密接しており、被取付面Ｗと吸盤体１（吸着面Ｓ）との間への気体の流入が防止された状態となっている。
【００３６】
以上のように、上記構成の掛け具によれば、吸盤体１の背面周縁部に環状凸部１０が突設されているので、押圧体３で吸盤体１の背面周縁部を押圧した際に、環状凸部１０は押し潰された態様となり、押圧体３による押圧力を環状凸部１０の形成領域に集中させることができる。これにより、環状凸部１０の形成領域に対応する吸盤体１の吸着面Ｓが、その他の領域の吸着面Ｓよりも密接な状態となり、被取付面Ｗと吸着面Ｓとの間への気体の流入を確実に防止することができ、吸着体の被取付面Ｗに対する吸着状態を長期に亘って維持することができる。
【００３７】
さらに、前記押圧体３に前記環状凸部１０と凹凸嵌合する環状凹部３２が形成され、該環状凹部３２は、押圧体３で吸盤体１を押圧した際に環状凸部１０を押圧可能に深さ設定されているので、押圧体３で吸盤体１を押圧した際に、吸盤体１に突設された環状凸部１０は、環状凹部３２の内周形状に即して弾性変形することになり、不均一に押し潰されることがない。これにより、環状凸部１０の不均一な変形に伴う吸盤体１の変形を抑制し、吸盤体１の周縁部を全周に亘って被取付面Ｗに均一な状態で密接させることができるので、安定した吸着を実現することができる。
【００３８】
尚、本発明の掛け具は、上記第一実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【００３９】
上記実施形態において、押圧体３の平板環状部３１に吸盤体１の環状凸部１０と凹凸嵌合させる環状凹部３２を形成したが、これに限定されるものではなく、例えば、環状凹部３２を形成することなく、平板環状部３１で直接吸盤体１の環状凸部１０を押圧するようにしてもよい。このようにしても、環状凸部１０の存在により、押圧体３による押圧力が環状凸部１０に集中的に作用することになり、該環状凸部１０の形成部分が被取付面Ｗに密接状態となる。したがって、上記実施形態と同様に、吸着面Ｓと被取付面Ｗとの間に負圧状態を長期に亘って維持することができる。
【００４０】
上記実施形態において、吸盤体１を皿状に構成したが、これに限定されるものではなく、例えば、吸盤体１を円形平板状に形成してもよい。このようにしても、フック体４を傾伏状態にすることで、吸盤体１の中央部が押圧体３側に引かれることになり、被取付面Ｗと吸着面Ｓとの間を負圧状態にすることができる。
【００４１】
また、上記実施形態において、押圧体３を吸盤体１の背面Ｒを覆うことができる外径に設定したが、吸盤体１の外径を押圧体３の外径よりも大きくし、押圧体３で吸盤体１の背面Ｒを押圧した（覆った）状態で、吸盤体１の外周縁部の一部が押圧体３から外部に露呈するように構成してもよい。ただし、上記環状凸部１０は、押圧体３に押圧され得る配置にすることは勿論のことである。このようにすれば、環状凸部１０から吸盤体１の外周縁まで距離が長くなり、被取付面Ｗに対する接触面積を広くすることができ、さらなる空気の流入防止を図ることができる。その上、該掛け具を被取付面Ｗから取り外すに際し、押圧体３による吸盤体１の押圧を解除した状態で、押圧体３から外方に出た吸盤体１の外周縁を容易に反り返すことができるので、被取付面Ｗと吸盤体１との間に空気を容易に流入させることができ、吸盤体１の吸着を容易に解除することができる。
【００４２】
上記実施形態において、フック体４を一つ設けるようにしたが、これに限定されるものではなく、例えば、図５に示す如く、連結杆２を基準にして左右振り分け状態となるように長尺な軸体５を連結杆２及び押圧板４１０，４１０に挿通し、上記フック体４とは別に該軸体５の両端部にフック体４ａ，４ｂを設けるようにしてもよい。この場合、軸体５の両端部に取り付けたフック体４ａ，４ｂには、上記実施形態にかかるフック体４の如き押圧部４１等を形成する必要するはない。
【００４３】
次に、本発明の第二実施形態にかかる掛け具について、添付図面を参酌しつつ説明する。なお、本実施形態にかかる掛け具は、第一実施形態と同一構成の吸盤体１、連結杆２、及び押圧体３を有しているので、以下説明において、これらの構成について同一の名称及び符号を付して説明を割愛し、第一実施形態と相違するフック体４についてのみ説明する。
【００４４】
本実施形態にかかる掛け具のフック体４は、図６及び図７に示す如く、軸体５を介して連結杆２に連結される連結部４５と、連結部４５に垂設されたフック部４２とで構成されている。
【００４５】
前記連結部４５は、所定間隔（連結杆２の外径よりやや広い間隔）を有して対向配置された一対の連結板４５ａ，４５ｂで構成されており、前記一対の連結板４５ａ，４５ｂは、同一の構成を有している。該一対の連結板４５ａ，４５ｂの各一端面（後述する介装部４７の一端）は、前記フック部４２に接続され、他端面は円弧面状に形成されて後述する第二摺接部４８ｃを構成している。
【００４６】
さらに、各連結板４５ａ，４５ｂには、連結杆本体２０から突出した軸体５の端部を挿入する挿入穴４９が、一端側から他端側に延びて長穴状に形成されており、後述する第一摺動部４８ａを構成する一側端面に対して他端側が離間して傾斜状態で形成されている。このように挿入穴４９を形成することで、押圧体３及び軸体５に対して相対移動可能に押圧体３の背面と軸体５との間に介装される介装部４７が、連結板４５ａ，４５ｂの一側端面（第一摺動部４８ａ）及び他端面（第二摺接部４８ｃ）と、挿入穴４９との間に形成されている。
【００４７】
前記介装部４７について具体的に説明すると、該介装部４７は、連結杆２（連結杆本体２０）及び軸体５の軸線と直交方向に移動させる際に、連結杆２及び軸体５の軸線に対して交差方向（以下、単に交差方向という）で押圧体３の背面と相対摺動する前記第一摺接部４８ａと、前記交差方向で軸体５と相対摺動する軸摺接部４８ｂとを備えている。
【００４８】
第一摺接部４８ａは、前記交差方向（本実施形態においては直交方向）に連結板４５ａ，４５ｂの一端側から他端側に向けて真っすぐ延びる平面で構成されており、本実施形態においては上述の如く連結板４５ａ，４５ｂの一側端面から構成されている。
【００４９】
軸摺接部４８ｂは、連結板４５ａ，４５ｂの一端側から他端側に延びる面で構成されており、本実施形態においては、前記挿入穴４９を形成する第一摺動部４８ａ側の平面状の内周面で構成されている。
【００５０】
前記第一摺接部４８ａ及び軸摺接部４８ｂは、連結杆本体２０の軸線方向における間隔が、連結板４５ａ，４５ｂの他端（前記交差方向の一方側）に向けて拡大するように形成され、介装部４７における第一摺接部４８ａと軸摺接部４８ｂとの間の部分が、連結板４５ａ，４５ｂの一端側ほど先細りした楔状を呈している。
【００５１】
第一摺接部４８ａと軸摺接部４８ｂとの間隔について、具体的に説明すると、連結板４５ａ，４５ｂの一端側における前記第一摺接部４８ａと軸摺接部４８ｂとの間隔（最小間隔Ｗ２）は、押圧体３を吸盤体１に対して非押圧状態にした際における、押圧体３の背面から軸体５までの距離と略同等、或いはそれよりも短くなるように設定され、連結板４５ａ，４５ｂの他端側における前記第一摺接部４８ａと軸摺接部４８ｂとの間隔（最大間隔Ｗ１）は、最小間隔Ｗ２に対して吸盤体１の背面周縁部が押圧体３で押圧された状態で、吸盤体１が弾性変形することにより連結杆２が軸線方向で先端側に移動できる略最大移動量分だけ広くなるように設定されている。従って、上述の如く第一摺接部４８ａ及び軸摺接部４８ｂは、平面状に形成されているので、これらは、相対的に傾斜した状態となっている。
【００５２】
さらに、該介装部４７は、前記交差方向の一方側にある第一摺接部４８ａの一端に連続して形成された円弧状の前記第二摺接部４８ｃを備えている。該第二摺接部４８ｃは、上述の如く、連結板４５ａ，４５ｂの他端面からなり、曲率半径Ｒが略一定に設定されている。したがって、第一摺接部４８ａ及び第二摺接部４８ｃは、連続面を形成している。
【００５３】
さらに、該介装部４７は、該介装部４７を一端側（フック体４をフック部４２側）に移動させた際に、軸摺接部４８ｂと相対摺動する軸体５が第一摺接部４８ａ側に向けて入り込むように、該介装部４７の他端側（前記交差方向の一方側）で軸摺接部４８ｂに隣接して軸受凹部４８ｄが形成されている。
【００５４】
該軸受凹部４８ｄは、軸摺接部４８ｂの面直交方向、且つ第一摺接部４８ａ側に連結板４５ａ，４５ｂを切り欠いて形成されており、軸摺接部４８ｂを基準面にして軸体５の半径以上の深さ（本実施形態においては軸体５の外径よりやや深い深さ）に設定されている。また軸受凹部４８ｄは、奥部の内周面が半円弧面状に形成されおり、該奥部の内周面に軸体５が摺動可能に面接触した状態で収容されるようになっている。
【００５５】
さらに、該軸受凹部４８ｄは、上記態様で収容された軸体５の軸線が、前記第二摺接部４８ｃの曲率中心と略一致するように形成されている。また、該軸受凹部４８ｄは、第一摺接部４８ａと面直交する方向で、第一摺接部４８ａから該軸受凹部４８ｄに収容した軸体５の軸線までの距離が、前記最大間隔Ｗ１よりもやや短く、且つ前記最小間隔Ｗ２より長くなるよう設定されている。これにより、軸受凹部４８ｄは、押圧体３で押圧された吸盤体１が弾性変形させ得る位置で軸体５を収容できるように形成されている。したがって、軸摺接部４８ｂと軸受凹部４８ｄの内周面とは、連続して形成され、本実施形態にかかる軸受凹部４８ｄは、挿入穴４９とともＬ字状の穴を形成している。
【００５６】
上記構成の掛け具を、被取付面である壁面Ｗに取り付ける場合、まず、軸体５が挿入穴４９の一端側に位置するようにしておく。そして、図８（イ）に示す如く、フック部４２を連結部４５よりも下方に位置させた状態で、吸盤体１の吸着面Ｓを壁面Ｗに当接させ、吸盤体１を壁面Ｗに向けて押し付ける。この状態で、皿状に形成された吸盤体１は、弾性変形して略平板状をなし、吸着面Ｓと壁面Ｗとの間の空気が略無くなった状態となるとともに、吸盤体１が自己弾性復元力により皿状に戻ろうとして吸着面Ｓと壁面Ｗとの間が負圧状態になる。
【００５７】
そして、この状態を維持したまま、図８（ロ）に示す如く、フック体４を下方に引っ張ると、フック体４の介装部４７が前記交差方向で押圧体３及び軸体５に対して相対移動することになる。つまり、介装部４７の第一摺動部４８ａが押圧体３の背面と相対摺動するとともに、軸摺接部４８ｂが軸体５の外周面に対して相対摺動することになる。そうすると、上述の如く、第一摺動部４８ａと軸摺接部４８ｂとの間の介装部４７は楔状に形成されているので、フック体４を下方（前記交差方向の他方側）に引っ張るにつれ、介装部４７が押圧体３の背面と軸体５との間隔を広げるように作用することになる。すなわち、第一摺動部４８ａと軸摺接部４８ｂとの間の介装部４７が、前記交差方向の他方側に押圧体３及び軸体５に対して相対移動することで、押圧体３及び軸体５が連結杆２の軸線方向で相対的に離間することになる。
【００５８】
そうすると、第一摺動部４８ａと軸摺接部４８ｂとの間隔が広がるにつれ、第一摺接部４８ａが押圧体３の背面に対して押圧した状態になって吸盤体１の背面周縁部が押圧体３に押圧されるとともに、軸体５を介して連結杆２が軸線方向で先端側に移動して、吸盤体１の中央部が押圧体３側に引かれて弾性変形することになる。
【００５９】
そして、図８（ハ）に示す如く、押圧体３の背面と軸体５との間に介装部４７の前記最大間隔Ｗ１部分が位置すると、吸盤体１の背面Ｒが押圧体３の内面に近づくため、吸盤体１の弾性変形の限界、すなわち連結杆２の軸線方向での移動が略限界に近づくことになる。そうすると、吸盤体１の弾性力によって連結杆２が抜止部２１側（押圧体３側）に引っ張られた状態となっているため、フック体４を下方に向けて引っ張ると、図８（ニ）に示す如く、軸体５が軸受凹部４８ｄと軸摺接部４８ｂとの接続部分を乗り越え、軸受凹部４８ｄに入り込み、フック体４における前記交差方向での移動が規制され、該掛け具の取り付けが完了する。
【００６０】
この状態で、軸体５は、押圧体３で押圧された吸盤体１を弾性変形させ得る位置に形成された軸受凹部４８ｄ内に収容されているので、吸盤体１は、自己の弾性復元力のみで壁面Ｗに吸着しているのではなく、連結杆２の強制的な引動による吸盤体１の弾性変形によって吸着面Ｓと壁面Ｗとの間の負圧状態が高まった状態で、壁面Ｗに吸着した状態となっている。なお、吸盤体１の環状凸部１０と押圧体３の環状凹部３２とは、凹凸嵌合した状態となっており（図４参照）、第一実施形態と同様に作用している。
【００６１】
そして、被掛物をフック部４２に掛けた際に、フック体４が軸体５周りで回転すると、図９（イ）に示す如く、第二摺接部４８ｃが押圧体３の背面を摺接することになるが、上述の如く、第二摺接部４８ｃは、曲率半径Ｒが一定で、且つ曲率中心が軸受凹部４８ｄに収容された軸体５の軸線と一致しているので、フック体４が回転して第二摺接部４８ｃが押圧体３の背面上を摺動しても、軸体５と押圧体３の背面までの相対距離が変化することがなく、第一摺接部４８ａが押圧体３を押圧しているときと同様に、第二摺接部４８ｃが押圧体３の背面を押圧するとともに、軸体５を介して連結杆２が引導され、吸盤体１を弾性変形させた状態で維持させた状態となる。
【００６２】
そして、上記掛け具を壁面Ｗから取り外すには、図９（ロ）に示す如く、フック部４２が連結杆２よりも上方に位置するまでフック体４を回転させると、挿入穴４９の他端側が軸受凹部４８ｄよりも押圧体３側に位置することになり、図９（ハ）に示す如く、吸盤体１の自己弾性復元力により連結杆２が抜止部２１側に引かれて軸体５が軸受凹部４８ｄから挿入穴４９に移動することになる。そうすると、図９（ホ）に示す如く、軸体５の軸線から押圧体３の背面に対向する第二摺接部４８ｃ、或いは、該第二摺接部４８ｃに接続された連結板４５ａ，４５ｂの他側端までの距離Ｗ３が、第二摺接部４８ｃの曲率半径Ｒよりも短くなり、連結杆２に対する強制的な引動、及び押圧体３に対する押圧が解除され、当該掛け具を壁面Ｗから取り外すことができる。
【００６３】
以上のように、上記構成の掛け具によれば、押圧体３の背面と軸体５との間に介装される介装部４７が、フック体４を前記交差方向の他方側に向けて引っ張った際に、前記交差方向で押圧体３の背面と相対摺動する第一摺接部４８ａと、前記交差方向で軸体５と相対摺動する軸摺接部４８ｂとを備え、前記第一摺接部４８ａ及び軸摺接部４８ｂは、介装部４７を前記交差方向の他方側（被掛物の吊り下げ方向）に移動させることで、押圧体３及び軸体５の間隔を相対的に押し広げるように、連結杆２の軸線方向の間隔が、一端側より他端側ほど広く設定されているので、フック体４を引っ張るだけで、押圧体３で吸盤体１の背面周縁部を押圧することができるとともに、連結杆２を引動して吸盤体１を弾性変形させ、被取付面Ｗと吸盤体１の吸着面Ｓとの間の負圧状態を高めることができる。
【００６４】
また、介装部４７には、軸摺接部４８ｂの他端に隣接して軸受凹部４８ｄが形成されているので、軸体５が該軸受凹部４８ｄに入り込むことで、介装部４７（フック体４）の前記交差方向での移動を規制することができる。また、被取付面Ｗと吸盤体１の吸着面Ｓとの間の負圧状態を高めた状態、すなわち、押圧体３で吸盤体１の背面周縁部を押圧するとともに、連結杆２を引動して吸盤体１を弾性変形させた状態で維持させることができる。
【００６５】
さらに、第一摺接部４８ａに連続して形成された第二摺接部４８ｃが、曲率半径Ｒを一定にして、曲率中心を軸受凹部４８ｄに入り込んだ軸体５の軸線と一致させて形成されているので、フック体４を軸体５周りで回転させても、押圧体３の背面と軸体５との相対距離を一定に保つことができ、押圧体３に対する押圧状態、連結杆２に対する引動状態を一定に保つことができる。これにより、吊り下げた被掛物の形態等に起因してフック体４を軸体５周りに回転しても、被取付面Ｗに対する取付状態を長期に亘って保つことができる。したがって、上記構成の掛け具は、被取付面に取り付けて小物等を掛けるように用いるだけでなく、例えば、対向する壁面（被取付面）のそれぞれに上記構成の掛け具を取り付け、壁面間にロープを張る等といった用途にも使用することができる。
【００６６】
尚、本発明の掛け具は、上記第二実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。
【００６７】
上記実施形態において、連結板４５ａ，４５ｂに挿入穴４９を形成することで、軸体５が摺動する軸摺接部４８ｂを形成するようにしたが、これに限定されるものではなく、例えば、上記構成の介装部を連結板として構成し、該介装部の先細りした一端部にフック部４２を連設するようにしてもよい。つまり、介装部４７に上記構成の第一摺接部４８ａ、第二摺接部４８ｃ、軸摺接部４８ｂ、及び軸受凹部４８ｄを形成していれば、押圧体３の背面と軸体５との間隔を相対的に押し広げることができ、軸体５を軸受凹部４８ｄに収容した状態で、第二摺接部４８ｃを押圧体３の背面に摺接させることができ、上記実施形態と同様の作用、効果を奏することができる。
【００６８】
上記実施形態において、軸摺接部４８ｂを真っ直ぐな面で構成したが、これに限定されるものではなく、例えば、円弧面などであってもよい。ただし、該円弧面からなる第二摺動部４８ｃの一端及び他端の配置は、上記実施形態と同様の配置となるようにすることは勿論である。
【００６９】

BACKGROUND OF THE INVENTION
The present invention relates to a hanging tool that is attached to a surface to be attached and hangs a hanging object.
[0002]
[Prior art]
Conventionally, various types of hooks have been provided as hooks that are attached to a mounting surface such as a wall surface to hang a hanger such as a small object. For example, as shown in FIG. A molded suction cup body 50, a connecting rod 51 projecting from the back surface of the suction cup body 50, a pressing body 52 that is loosely inserted into the suction cup body 50 and disposed on the back side of the suction cup body 50, A shaft body 53 attached to the connecting rod 51 protruding to the back side of the pressing body 52 with its axis orthogonal to each other, and a shape set so as to be able to suspend the object to be hung, rotate through the shaft body 53 to the connecting rod 51. What is comprised with the hook body 54 connected so that it is possible is known.
[0003]
The pressing body 52 has rigidity, an outer diameter is set so that the suction cup body 50 can be covered, and an annular convex portion 55 is formed on the peripheral portion of the surface facing the suction cup body 50. Yes. The hook body 54 includes a pressing portion 56 that is connected to the connecting rod 51 so that the pressing body 52 can be pressed, and a hook portion 57 that is connected to one end of the pressing portion 56 and on which an object is hung. .
[0004]
The pressing portion 56 is formed in a concentric cam shape whose other end rotates around the shaft body 53, thereby causing the hook portion 57 located in the axial direction of the connecting rod 51 to be tilted. Thus, by rotating the hook body 54, a convex curved surface 58 that slides and gradually presses the back surface of the pressing body 52 is provided. The pressing portion 56 includes a flat portion 59 that is connected to one end of the bending surface 58 in the bending direction and faces the back surface of the pressing portion 56 substantially in parallel when the hook portion 57 is inclined. In addition, a locking convex portion 60 is formed at a connection portion between the flat portion 59 and the curved surface 58. Thus, the relative positional relationship between the shaft body 53 and the pressing position of the pressing portion 56 with respect to the pressing body 52 restricts the rotation of the pressing portion 56 with a snap action so that the hook body 54 is maintained in a tilted state. It is configured.
[0005]
The hanging tool having the above-described configuration is configured so that the hook body 54 is inclined with the shaft body 53 as a fulcrum, as shown in FIG. Due to the action, the pressing body 52 and the shaft body 53 are relatively separated from each other, and the pressing body 52 presses the peripheral edge of the back surface of the suction cup body 50 so that the annular convex section 55 sinks into the suction cup body 50. The pressing force is concentrated on the portion to surely prevent the inflow of air from the peripheral portion of the suction cup body 50, and the central portion of the suction cup body 50 is elastically deformed toward the pressing body 52 via the shaft body 52 and the connecting rod 51. The negative pressure state between the mounted surface W and the suction cup 1 is increased to obtain a high suction capability. (For example, see Patent Document 1)
[0006]
[Patent Document 1]
Utility Model Registration No. 2568453
[0007]
[Problems to be solved by the invention]
However, since the annular protrusion 55 is formed on the inner surface of the pressing body 52 that presses the back peripheral edge of the suction cup body 50 having flexibility and elasticity, the hanging tool having the above-described configuration is attached to the mounting surface for a long period of time. If it is left as it is or if it is repeatedly attached and detached, the suction cup body 50 may retain the mold in which the annular convex portion 55 is recessed.
[0008]
Then, when the hanging tool is removed and attached to the attachment surface again, even if the pressing body 52 presses the peripheral edge of the back surface of the suction cup body 50, the annular convex portion 55 is only in the remaining mold. In some cases, the pressing force of the pressing body 52 cannot be applied to the suction cup body 50 intensively as in the case of a new article, and the air inflow prevention function from the outer periphery of the suction cup body 50 cannot be exhibited. . For this reason, air may flow in from the outer peripheral edge of the suction cup body 50 over time, and may drop from the mounted surface.
[0009]
Further, as described above, the hanging tool rotates the pressing portion 56 by the relative positional relationship between the shaft body 53 that pivotally attaches the pressing portion 56 to the connecting rod 51 and the pressing position of the pressing portion 56 with respect to the pressing body 52. Since the hook body 54 is maintained in a lying state, the pressing body 52 is pressed against the outer peripheral edge of the suction cup body 50 and the suction body 50 is forcedly pulled. When the load rotated around the body 53 acts on the hook body 54, the tilted state of the hook body 54 may be released.
[0010]
If it does so, while the press state with respect to the outer periphery part of the suction cup body 50 by the press body 52 will be cancelled | released, the forced pulling state of the suction cup body 50 will be cancelled | released, and the negative pressure state between the to-be-attached surface W and the suction cup body 50 will be cancelled | released. In some cases, the hook could fall off the surface to be attached without being able to maintain.
[0011]
Therefore, in view of such a situation, the present invention reliably ensures that air flows between the mounted surface and the suction cup body even when left in the mounted state or repeatedly attached to and detached from the mounted surface. A first object is to provide a hanging tool that can be prevented, and a hanging tool that can maintain the suction state of the suction cup body with respect to the mounting surface is provided regardless of the undulation state of the hook body that hangs the hanging object. This is the second task.
[0012]
[Means for Solving the Problems]
The hanging tool according to the present invention has been made to solve the first problem, and according to claim 1, a sucker body having flexible elasticity and a connection projecting from the back surface of the sucker body. A pressing body in which the connecting rod is loosely inserted, and a hook body that is connected to the connecting rod protruding to the back side of the pressing body and on which an object is hung. Is a hanging tool configured to press the back peripheral edge of the suction cup body with a pressing body and to elastically deform the suction cup body by moving the connecting rod relative to each other in the axial direction and the separation direction, The suction cup body is provided with an annular convex portion protruding toward the pressing body at the peripheral edge of the back surface.
[0013]
According to the hanging tool having the above configuration, the suction cup body includes the annular convex portion protruding toward the pressing body at the rear peripheral edge portion. Therefore, when the pressing body presses the rear peripheral edge portion of the suction cup body, the annular convex portion is pressed. It becomes a crushed aspect. Then, the pressing force concentrates on the portion where the annular convex portion is formed, and this portion is in a state closer to the attached surface than the other portions, so that gas flows between the attached surface and the suction cup body. Can be reliably prevented, and the adsorbed state of the adsorbent to the attached surface can be maintained for a long period of time.
[0014]
Further, since the annular convex portion has flexible elasticity like the suction cup body, it may be in a slightly flat state when the pressing by the pressing body is released. It becomes the aspect which protruded from the back surface. Therefore, even if the unit is left in a state of being pressed against the pressing body (attached state) for a long time or is repeatedly attached to and detached from the attached surface, Due to the presence of the part, the pressing force acts in a concentrated manner, and it is possible to reliably prevent the inflow of gas between the mounted surface and the suction cup body, and the adsorption state of the adsorbing body to the mounted surface over a long period of time. Can be maintained.
[0015]
Furthermore, as described in claim 2, it is preferable that the pressing body is formed with an annular recess that is concavo-convexly engaged with the annular projection, and the annular recess is configured to be able to press the annular projection. In this way, when the suction cup body is pressed against the pressing body, the annular convex portion is fitted into the annular concave portion in a pressed state, and is elastically deformed in accordance with the inner shape of the annular concave portion. It can prevent being crushed. Therefore, the peripheral edge portion of the suction cup body is in close contact with the surface to be attached in a uniform state over the entire circumference of the suction cup body, and stable suction can be realized.
[0016]
The invention described in claim 3 has been made to solve the second problem. A suction cup body having flexibility and elasticity, a connecting rod projecting on the back surface of the suction cup body, and the connecting rod are free to play. A pressing body that is inserted, a shaft body that is connected to the connecting rod that protrudes on the back side of the pressing body with an axis orthogonal thereto, and a hook body that is rotatably provided around the shaft body. The pressing body and the connecting rod are moved relative to each other in the axial direction and the separating direction of the connecting rod, whereby the back peripheral edge of the suction cup body is pressed by the pressing body and the suction cup body is elastically deformed. The hook body includes an interposition part interposed between the pressing body and the shaft body, and a hook part that is connected to the interposition part and on which an object is hung, The interposition part includes a first sliding contact portion that slides relative to the pressing body in the cross direction with respect to the axis of the connecting rod and the shaft body, and the shaft body in the cross direction. A shaft sliding contact portion that slides relatively, an arc-shaped second sliding contact portion that is connected to the first sliding contact portion on one side in the intersecting direction and slides relative to the pressing body, and one side in the intersecting direction And a bearing concave portion that is formed adjacent to the shaft sliding contact portion, and the shaft body enters toward the first sliding contact portion side, and the axial distance between the first sliding contact portion and the shaft sliding contact portion in the axial direction. Is set so as to expand toward one side in the crossing direction, the radius of curvature of the second sliding contact portion is set to be substantially constant, and the axis of the shaft body in which the bearing recess enters is the curvature of the second sliding contact portion. It is characterized by being configured to substantially coincide with the center.
[0017]
According to the hanging tool of the above configuration, the hook body includes an interposed part interposed between the pressing body and the shaft body, and a hook part that is connected to the interposed part and on which an object is hung. Since the interval in the axial direction of the connecting rod between the first sliding contact portion and the shaft sliding contact portion is set so as to increase toward one side in the intersecting direction, it is interposed between the pressing body and the shaft body. When the portion (hook body) is relatively moved to the other side in the intersecting direction, the distance between the pressing body and the shaft body is increased as the distance between the first sliding contact portion and the shaft sliding contact portion changes. Will be relatively separated from each other.
[0018]
Then, along with the relative movement of the pressing body and the shaft body, the pressing body presses the peripheral edge of the back surface of the suction cup body, the connecting rod attached with the shaft body moves in the axial direction, and the suction cup body moves to the pressing body side. It will be elastically deformed by being pulled by. In this state, a tensile force is applied to pull the shaft body toward the pressing body by the elastic restoring force of the suction cup body.
[0019]
And since the interposition part is provided with the bearing recessed part which is formed adjacent to the shaft sliding contact part on one side of the crossing direction and the shaft body enters toward the first sliding contact part side, Further, when moving toward the other side in the intersecting direction, the shaft body sliding relative to the shaft sliding contact portion enters the bearing recess by the pulling force, and the interposition portion is moved in the intersecting direction. It becomes a locked state, and it becomes possible to hang an object to be hooked.
[0020]
The intervening portion further includes an arc-shaped second sliding contact portion that is connected to the first sliding contact portion on one side in the intersecting direction and slides relative to the pressing body, and the second sliding contact portion has a curvature. The radius is set to be substantially constant, and the bearing recess is configured so that the axis of the shaft body that is inserted substantially coincides with the center of curvature of the second sliding contact portion, so even if the hook body rotates around the shaft body, The distance from the contact (pressing) position to the pressing body at the second sliding contact portion to the axis of the shaft body is substantially constant, and the pressing state of the pressing body with respect to the suction cup body and the elastic deformation state of the suction cup body are kept constant. Will be. Thereby, the suction | attraction state of the suction cup body with respect to a to-be-attached surface can be maintained irrespective of the undulation of the hook body (hook part) which hangs a to-be-suspended object.
[0021]
Further, as described in claim 4, it is preferable that each of the first sliding contact portion and the shaft sliding contact portion is formed with a straight surface. If it does in this way, between the said 1st sliding contact part and a shaft sliding contact part will exhibit a wedge shape, and an intervention part will move smoothly to the one end side (hook part side) of an intervention part. In addition, the pressing body and the shaft body can be smoothly moved relative to each other.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a hanging tool according to a first embodiment of the present invention will be described with reference to the accompanying drawings.
[0023]
As shown in FIGS. 1 and 2, the hanging tool according to the present embodiment includes a suction cup body 1 that is attracted to a mounting surface W such as a wall surface, and a rod-like connecting rod 2 that is provided on the back surface of the suction cup body 1. The connecting rod 2 is loosely inserted, the pressing body 3 disposed on the back side of the suction cup body 1, the hook body 4 for hanging an object (not shown) such as an accessory or a bag, and the hook body 4 And a shaft body 5 that connects the shaft to the tip of the connecting rod 2.
[0024]
The suction cup body 1 is formed by molding a flexible elastic rubber, synthetic resin or the like into a dish shape having a circular shape in plan view, and a concave surface is set to an adsorption surface S to be brought into contact with and adsorbed to the mounted surface W. The convex surface side is set to the back surface R.
[0025]
The suction cup 1 has a negative pressure between the suction surface S and the mounted surface W due to a self-elastic restoring force to return to a dish shape by bringing substantially the entire suction surface S into contact with the mounted surface W. In view of the ease of contact of the suction surface S to the mounted surface W and the self-elastic restoring force, the central portion in plan view It is formed so that the wall thickness gradually decreases from the edge toward the periphery. Further, an annular convex portion 10 that protrudes toward the pressing body 3 is formed on the peripheral portion of the back surface R of the suction cup body 1 (hereinafter referred to as the back peripheral portion). The annular protrusion 10 is integrally formed when the suction cup body 1 is formed, and has flexible elasticity.

The connecting rod 2 includes a rod-shaped connecting rod main body 20 and a disc-shaped retaining portion 21 concentrically connected to the base end portion of the connecting rod main body 20. The connecting rod body 20 has a through hole 200 through which the shaft body 5 is inserted at the tip, and the retaining portion 21 is formed so that the connecting rod body 20 is concentric with the suction cup body 1. When the suction cup body 1 is molded, the suction cup body 1 is embedded in a substantially central portion in plan view. Thereby, the connecting rod 2 has a mode in which the connecting rod main body 20 protrudes from the back surface R of the suction cup body 1.
[0027]
The pressing body 3 is a dish-shaped resin molded product having rigidity, the central portion in plan view is formed in a circular flat plate shape, and the outer diameter is set so as to cover the back surface R of the suction cup body 1. Has been. The pressing body 3 has a through hole 30 for loosely inserting the connecting rod 2 (connecting rod main body 20) in a substantially central portion in plan view, and a flat plate annular portion 31 formed on the outer peripheral edge portion. The rear peripheral portion of the suction cup body 1 can be pressed.
[0028]
In the pressing body 3, an annular recess 32 is formed on the inner surface of the flat plate annular portion 31 that faces the suction cup body 1, and the annular projection 10 of the suction cup body 1 fits into the concave and convex portions. The annular recess 32 is set to a depth slightly shallower than the protruding amount of the annular protrusion 10, and the annular recess 32 is pressed when the back peripheral edge of the suction cup body 1 is pressed by the pressing body 3 (flat plate annular portion). The annular convex part 10 fitted to is pressed and deformed.
[0029]
The hook body 4 is a resin molded product having rigidity, similar to the pressing body 3, and is connected to the connecting rod 2 via the shaft body 5 and presses the back surface of the pressing body 3, The hook portion 42 is connected to one end of the portion 41 and has a shape set so that the object can be suspended.
[0030]
The pressing portion 41 is composed of a pair of pressing plates 410 and 410 that are opposed to each other with an interval through which the connecting rod main body 20 can be interposed, and the hook portion 42 is one end of the pair of pressing plates 410 and 410. It is arranged so that it may mutually connect. The pair of pressing plates 410 and 410 are formed with through holes 411 through which the shaft body 5 is inserted, and each pressing plate 410 and 410 has an eccentricity set with the center of the through hole 411 as the center of rotation. It is formed in a cam shape.
[0031]
When the hook body 4 is rotated around the shaft body 5 in one direction so that the hook body 4 is tilted, the pressing portion 41 is formed in an eccentric cam shape. A convex curved surface 412 that slides on the back surface and gradually presses the pressing body 3 is formed on the end surface. The pressing portion 41 includes a flat portion 413 that is connected to one end of the bending surface 412 in the bending direction and faces the back surface of the pressing portion 41 substantially in parallel when the hook body 4 is inclined. In addition, a locking convex portion 414 is formed at a connection portion between the flat portion 413 and the curved surface 412. Thus, the relative position relationship between the pressing position of the pressing portion 41 and the shaft body 5 with respect to the pressing body 3 restricts the rotation of the pressing portion 41 with a snap action so that the hook body 4 is maintained in a tilted state. It is configured.
[0032]
The shaft body 5 is configured such that both end portions protrude from the connecting rod 2 in a state of being inserted into the insertion hole 200 of the connecting rod 2, and the both end portions are through holes of the pair of pressing plates 410 and 410. It is set to an outer diameter that can be inserted into 411,411. In addition, the shaft body 5 according to the present embodiment is formed in a taper pin shape with an outer diameter gradually decreasing from one end to the other end. When the shaft body 5 is inserted into the insertion hole 200 of the connecting rod 2, both ends are connected to the connecting rod. 2 and is configured to be press-fitted into the insertion hole 200.
[0033]
In order to attach the hanging tool having the above-described configuration to the attachment surface W, first, a portion of the pressing portion 41 (the pressing plates 410 and 410) where the curvature radius of the curved surface 412 is minimized is opposed to the back surface of the pressing body 3. The hook body 4 is raised. In this state, the pressing portion 41 is not in a state of being pressed against the pressing body 3, and the pressing body 3 is in a state where it can move between the hook body 4 and the suction cup body 1.
[0034]
Then, the suction cup body 1 is pressed against the mounting surface W so that the suction surface S of the suction cup body 1 substantially contacts the mounting surface W. In this state, as shown in FIG. Rotate around the shaft body 5. Then, as described above, as the radius of curvature of the curved surface 412 of the pressing portion 41 of the hook body 4 changes, the pressing portion 41 presses the back surface of the pressing body 3 and the pressing body 3 presses toward the suction cup body 1. At the same time, the connecting rod 2 is pulled in the axial direction, and the substantially central portion of the suction cup body 1 is pulled toward the pressing body 3 side. If it does so, between the suction surface S of the suction cup body 1 and the to-be-attached surface W will be in a negative pressure state, and the suction cup body 1 will be in the state to which the to-be-attached surface W was adsorbed. Then, after the locking convex portion 414 presses the back surface of the pressing body 3, when the flat portion 413 faces the back surface of the pressing body 3, the pressing body 3 presses the suction cup body 1 and the connecting rod 2. While the guiding state is maintained, the rotation of the pressing portion 41 around the shaft body 5 is restricted, and the hook body 4 is maintained in a tilted state.
[0035]
In this state, as shown in FIG. 4, the annular convex portion 10 of the suction cup body 1 is fitted into the annular concave portion 32 of the pressing body 3, and the annular convex portion 10 is deformed by the pressing of the suction cup body 1 by the pressing body 3. It is deformed according to the shape of the annular recess 32 without being crushed unevenly. Therefore, the suction surface S at the peripheral portion of the suction cup body 1 is in close contact with the mounted surface W in a uniform state over the entire circumference of the peripheral portion of the suction cup body 1, and the mounted surface W and the suction cup body 1 (adsorption) In this state, inflow of gas to the surface S) is prevented.
[0036]
As described above, according to the hanging tool configured as described above, since the annular convex portion 10 protrudes from the rear peripheral edge portion of the suction cup body 1, when the rear peripheral edge portion of the suction cup body 1 is pressed by the pressing body 3. The annular protrusion 10 is crushed and the pressing force by the pressing body 3 can be concentrated on the formation area of the annular protrusion 10. As a result, the suction surface S of the suction cup body 1 corresponding to the formation region of the annular protrusion 10 becomes closer to the suction surface S of the other region, and the gas between the attached surface W and the suction surface S Inflow can be reliably prevented, and the adsorbed state of the adsorbent with respect to the mounting surface W can be maintained for a long period of time.
[0037]
Further, the pressing body 3 is formed with an annular recess 32 that is concavo-convexly engaged with the annular protrusion 10, and the annular recess 32 can press the annular protrusion 10 when the suction body 1 is pressed by the pressing body 3. Since the depth is set, when the suction cup body 1 is pressed by the pressing body 3, the annular protrusion 10 protruding from the suction cup body 1 is elastically deformed in accordance with the inner peripheral shape of the annular recess 32. And will not be crushed unevenly. Thereby, since the deformation | transformation of the suction cup body 1 accompanying the non-uniform deformation | transformation of the cyclic | annular convex part 10 can be suppressed, the peripheral part of the suction cup body 1 can be made to closely_contact | adhere to the to-be-attached surface W over a perimeter. Stable adsorption can be realized.
[0038]
The hanging tool of the present invention is not limited to the first embodiment described above, and various modifications can be made without departing from the scope of the present invention.
[0039]
In the said embodiment, although the annular recessed part 32 which carries out uneven fitting with the annular convex part 10 of the suction cup body 1 was formed in the flat plate annular part 31 of the press body 3, it is not limited to this, For example, the annular recessed part 32 is formed. You may make it press the annular convex part 10 of the suction cup body 1 directly with the flat plate annular part 31 without forming. Even in this case, due to the presence of the annular convex portion 10, the pressing force by the pressing body 3 acts on the annular convex portion 10, and the formation portion of the annular convex portion 10 is in close contact with the mounting surface W. It becomes a state. Therefore, similarly to the above embodiment, a negative pressure state can be maintained between the suction surface S and the mounted surface W for a long period of time.
[0040]
In the said embodiment, although the suction cup body 1 was comprised in the dish shape, it is not limited to this, For example, you may form the suction cup body 1 in circular flat form. Even if it does in this way, the center part of the suction cup body 1 will be pulled to the press body 3 side by making the hook body 4 in a tilted state, and a negative pressure is applied between the to-be-attached surface W and the adsorption surface S. Can be in a state.
[0041]
Moreover, in the said embodiment, although the press body 3 was set to the outer diameter which can cover the back surface R of the suction cup body 1, the outer diameter of the suction cup body 1 is made larger than the outer diameter of the press body 3, and the press body 3 is set. In the state where the back surface R of the suction cup body 1 is pressed (covered), a part of the outer peripheral edge of the suction cup body 1 may be exposed from the press body 3 to the outside. However, it goes without saying that the annular convex portion 10 is arranged so as to be pressed by the pressing body 3. If it does in this way, distance from the annular convex part 10 to the outer periphery of the suction cup body 1 becomes long, the contact area with respect to the to-be-attached surface W can be enlarged, and the inflow prevention of the further air can be aimed at. In addition, when the hook is removed from the mounting surface W, the outer peripheral edge of the suction cup body 1 protruding outward from the pressing body 3 is easily warped in a state in which the suction body 1 is not pressed by the pressing body 3. Therefore, air can be easily allowed to flow between the attachment surface W and the suction cup body 1, and the suction of the suction cup body 1 can be easily released.
[0042]
In the above embodiment, one hook body 4 is provided. However, the present invention is not limited to this. For example, as shown in FIG. The shaft body 5 may be inserted into the connecting rod 2 and the pressing plates 410 and 410, and the hook bodies 4 a and 4 b may be provided at both ends of the shaft body 5 separately from the hook body 4. In this case, the hook bodies 4a and 4b attached to both ends of the shaft body 5 do not need to be formed with the pressing portion 41 or the like as in the hook body 4 according to the above embodiment.
[0043]
Next, a hanging tool according to a second embodiment of the present invention will be described with reference to the attached drawings. In addition, since the hanging tool concerning this embodiment has the suction cup body 1, the connection rod 2, and the press body 3 of the same structure as 1st embodiment, in the following description, the same name and about these structures are given. Only the hook body 4 different from the first embodiment will be described with reference numerals being omitted.
[0044]
As shown in FIGS. 6 and 7, the hook body 4 of the hanging tool according to the present embodiment includes a connecting portion 45 that is connected to the connecting rod 2 via the shaft body 5, and a hook portion that is suspended from the connecting portion 45. 42.
[0045]
The connecting portion 45 is composed of a pair of connecting plates 45a and 45b arranged to face each other with a predetermined interval (slightly wider than the outer diameter of the connecting rod 2), and the pair of connecting plates 45a and 45b are Have the same configuration. One end surfaces of the pair of connecting plates 45a and 45b (one end of an intervening portion 47 to be described later) are connected to the hook portion 42, and the other end surface is formed in an arcuate surface shape, and a second sliding contact portion 48c to be described later. Is configured.
[0046]
Further, each connecting plate 45a, 45b has an insertion hole 49 for inserting the end portion of the shaft body 5 protruding from the connecting rod main body 20, extending from one end side to the other end side, and is formed in a long hole shape. The other end side is separated from the one side end face constituting the first sliding portion 48a described later, and is formed in an inclined state. By forming the insertion hole 49 in this way, the interposition part 47 interposed between the back surface of the pressing body 3 and the shaft body 5 so as to be relatively movable with respect to the pressing body 3 and the shaft body 5 is connected. It is formed between one end face (first sliding part 48 a) and the other end face (second sliding contact part 48 c) of the plates 45 a and 45 b and the insertion hole 49.
[0047]
The intervention part 47 will be specifically described. When the intervention part 47 is moved in a direction orthogonal to the axis of the connection rod 2 (connection rod main body 20) and the shaft body 5, the connection rod 2 and the shaft body 5. The first sliding contact portion 48a that slides relative to the back surface of the pressing body 3 in the intersecting direction (hereinafter simply referred to as the intersecting direction) with respect to the axis of the shaft, and the axial sliding contact that relatively slides relative to the shaft body 5 in the intersecting direction. Part 48b.
[0048]
The first sliding contact portion 48a is configured by a plane that extends straight from one end side to the other end side of the coupling plates 45a and 45b in the intersecting direction (in the orthogonal direction in the present embodiment). As described above, the connecting plates 45a and 45b are composed of one end face.
[0049]
The shaft sliding contact portion 48b is configured by a surface extending from one end side to the other end side of the coupling plates 45a and 45b. In the present embodiment, the flat surface on the first sliding portion 48a side forming the insertion hole 49 is formed. It is comprised by the inner peripheral surface of a shape.
[0050]
The first sliding contact portion 48a and the shaft sliding contact portion 48b are formed such that the interval in the axial direction of the connecting rod main body 20 increases toward the other end of the connecting plates 45a and 45b (one side in the intersecting direction). The portion between the first sliding contact portion 48a and the shaft sliding contact portion 48b in the interposition portion 47 has a wedge shape that tapers toward one end side of the connecting plates 45a and 45b.
[0051]
The distance between the first sliding contact portion 48a and the shaft sliding contact portion 48b will be specifically described. The distance between the first sliding contact portion 48a and the shaft sliding contact portion 48b on one end side of the connecting plates 45a and 45b (minimum). The interval W2) is set so as to be substantially equal to or shorter than the distance from the back surface of the pressing body 3 to the shaft body 5 when the pressing body 3 is not pressed against the suction cup body 1. The distance between the first sliding contact portion 48a and the shaft sliding contact portion 48b on the other end side of the connecting plates 45a and 45b (maximum spacing W1) is such that the rear peripheral edge of the suction cup body 1 is pressed against the minimum spacing W2. In the pressed state, the suction cup body 1 is elastically deformed so that the connecting rod 2 is widened by an approximately maximum moving amount that can move to the tip side in the axial direction. Accordingly, as described above, the first sliding contact portion 48a and the shaft sliding contact portion 48b are formed in a flat shape, and therefore are in a relatively inclined state.
[0052]
Furthermore, the interposition part 47 includes the arc-shaped second sliding contact part 48c formed continuously at one end of the first sliding contact part 48a on one side in the intersecting direction. As described above, the second sliding contact portion 48c is composed of the other end surfaces of the connecting plates 45a and 45b, and the curvature radius R is set to be substantially constant. Accordingly, the first sliding contact portion 48a and the second sliding contact portion 48c form a continuous surface.
[0053]
Further, when the interposition part 47 is moved to one end side (the hook body 4 is on the hook part 42 side), the shaft body 5 that slides relative to the shaft sliding contact part 48b is the first. A bearing recess 48d is formed adjacent to the shaft sliding contact portion 48b on the other end side (one side in the intersecting direction) of the interposition portion 47 so as to enter the sliding contact portion 48a side.
[0054]
The bearing recess 48d is formed by cutting the connecting plates 45a and 45b in the direction perpendicular to the surface of the shaft sliding contact portion 48b and on the first sliding contact portion 48a side, and the shaft sliding contact portion 48b is used as a reference surface. The depth is set to a depth equal to or larger than the radius of the body 5 (in this embodiment, a depth slightly deeper than the outer diameter of the shaft body 5). Further, the bearing recess 48d is formed so that the inner peripheral surface of the inner part is a semicircular arc surface, and the shaft body 5 is slidably brought into surface contact with the inner peripheral surface of the inner part. Yes.
[0055]
Further, the bearing recess 48d is formed so that the axis of the shaft body 5 accommodated in the above-described manner substantially coincides with the center of curvature of the second sliding contact portion 48c. Further, the bearing recess 48d has a distance from the first sliding contact portion 48a to the axis of the shaft body 5 accommodated in the bearing recess 48d in a direction perpendicular to the first sliding contact portion 48a from the maximum interval W1. It is set to be slightly shorter and longer than the minimum interval W2. Thereby, the bearing recessed part 48d is formed so that the shaft body 5 can be accommodated in the position where the suction cup body 1 pressed by the pressing body 3 can be elastically deformed. Therefore, the shaft sliding contact portion 48b and the inner peripheral surface of the bearing recess 48d are formed continuously, and the bearing recess 48d according to the present embodiment forms an L-shaped hole together with the insertion hole 49.
[0056]
When the hanging tool having the above-described configuration is attached to the wall surface W that is the attachment surface, first, the shaft body 5 is positioned on one end side of the insertion hole 49. 8 (a), the suction surface S of the suction cup body 1 is brought into contact with the wall surface W in a state where the hook portion 42 is positioned below the connecting portion 45, and the suction cup body 1 is brought into contact with the wall surface W. Press toward. In this state, the suction cup body 1 formed in a dish shape is elastically deformed to form a substantially flat plate shape, and the air between the suction surface S and the wall surface W is substantially eliminated, and the suction cup body 1 is self The space between the suction surface S and the wall surface W is in a negative pressure state so as to return to the dish shape by the elastic restoring force.
[0057]
If the hook body 4 is pulled downward while maintaining this state, as shown in FIG. 8 (b), the interposition part 47 of the hook body 4 is moved against the pressing body 3 and the shaft body 5 in the crossing direction. It will move relative. That is, the first sliding part 48 a of the interposition part 47 slides relative to the back surface of the pressing body 3, and the shaft sliding contact part 48 b slides relative to the outer peripheral surface of the shaft body 5. Then, as described above, since the interposition part 47 between the first sliding part 48a and the shaft sliding contact part 48b is formed in a wedge shape, the hook body 4 is pulled downward (the other side in the intersecting direction). Accordingly, the interposition part 47 acts to widen the distance between the back surface of the pressing body 3 and the shaft body 5. That is, the interposition part 47 between the first sliding part 48a and the shaft sliding contact part 48b moves relative to the pressing body 3 and the shaft body 5 to the other side in the intersecting direction, so that the pressing body 3 And the shaft body 5 is relatively separated in the axial direction of the connecting rod 2.
[0058]
Then, as the distance between the first sliding portion 48a and the shaft sliding contact portion 48b increases, the first sliding contact portion 48a presses against the back surface of the pressing body 3, and the back peripheral portion of the suction cup body 1 While being pressed by the pressing body 3, the connecting rod 2 moves to the tip end side in the axial direction via the shaft body 5, and the central portion of the suction cup body 1 is pulled toward the pressing body 3 and elastically deforms. .
[0059]
Then, as shown in FIG. 8 (c), when the maximum interval W1 portion of the interposition part 47 is positioned between the back surface of the pressing body 3 and the shaft body 5, the back surface R of the suction cup body 1 is the inner surface of the pressing body 3. Therefore, the limit of elastic deformation of the suction cup body 1, that is, the movement of the connecting rod 2 in the axial direction approaches the limit. Then, since the connecting rod 2 is pulled to the retaining portion 21 side (the pressing body 3 side) by the elastic force of the suction cup body 1, when the hook body 4 is pulled downward, FIG. As shown in FIG. 4, the shaft body 5 gets over the connecting portion between the bearing recess 48d and the shaft sliding contact portion 48b, enters the bearing recess 48d, and the movement of the hook body 4 in the crossing direction is restricted, and the hook is attached. Complete.
[0060]
In this state, since the shaft body 5 is housed in the bearing recess 48d formed at a position where the suction cup body 1 pressed by the pressing body 3 can be elastically deformed, the suction cup body 1 has its own elastic restoring force. In the state where the negative pressure state between the suction surface S and the wall surface W is increased by the elastic deformation of the suction cup body 1 due to the forced pulling of the connecting rod 2, It is in a state of being adsorbed on the surface. In addition, the annular convex part 10 of the suction cup body 1 and the annular concave part 32 of the pressing body 3 are in an unevenly fitted state (see FIG. 4), and act in the same manner as in the first embodiment.
[0061]
Then, when the hook body 4 is rotated around the shaft body 5 when the object is hung on the hook portion 42, the second sliding contact portion 48c is in sliding contact with the back surface of the pressing body 3 as shown in FIG. However, as described above, the second sliding contact portion 48c has the constant radius of curvature R and the center of curvature coincides with the axis of the shaft body 5 accommodated in the bearing recess 48d. Even if the second sliding contact portion 48c slides on the back surface of the pressing body 3, the relative distance between the shaft body 5 and the back surface of the pressing body 3 does not change, and the first sliding contact portion 48a does not change. In the same manner as when pressing the pressing body 3, the second sliding contact portion 48c presses the back surface of the pressing body 3, and the connecting rod 2 is guided through the shaft body 5 to elastically deform the suction cup body 1. It will be in the state maintained in the made state.
[0062]
In order to remove the hook from the wall surface W, as shown in FIG. 9B, when the hook body 4 is rotated until the hook portion 42 is positioned above the connecting rod 2, the other end of the insertion hole 49 is removed. As shown in FIG. 9C, the connecting rod 2 is pulled toward the retaining portion 21 by the self-elastic restoring force of the suction cup body 1 as shown in FIG. Moves from the bearing recess 48d to the insertion hole 49. Then, as shown in FIG. 9E, the second sliding contact portion 48c facing the back surface of the pressing body 3 from the axis of the shaft body 5 or the connecting plates 45a and 45b connected to the second sliding contact portion 48c. The distance W3 to the other side end is shorter than the radius of curvature R of the second sliding contact portion 48c, the forced pulling on the connecting rod 2 and the pressing on the pressing body 3 are released, and the hanging tool is attached to the wall surface W. Can be removed from.
[0063]
As described above, according to the hanging tool configured as described above, the interposition part 47 interposed between the back surface of the pressing body 3 and the shaft body 5 faces the hook body 4 to the other side in the crossing direction. A first sliding contact portion 48a that slides relative to the back surface of the pressing body 3 in the intersecting direction when pulled, and a shaft sliding contact portion 48b that slides relative to the shaft body 5 in the intersecting direction. The one sliding contact portion 48a and the shaft sliding contact portion 48b move the interposition portion 47 to the other side in the intersecting direction (the hanging direction of the object to be hung), so that the distance between the pressing body 3 and the shaft body 5 is relatively set. Since the distance between the connecting rods 2 in the axial direction is set to be wider from the one end side to the other end side, the rear peripheral edge portion of the suction cup body 1 can be moved by the pressing body 3 only by pulling the hook body 4. While being able to press, the connecting rod 2 is pulled to elastically deform the suction cup body 1 so that the attachment surface W and the suction cup body 1 It is possible to increase the negative pressure state between the Chakumen S.
[0064]
Further, since the bearing recess 48d is formed adjacent to the other end of the shaft sliding contact portion 48b in the interposition portion 47, the shaft portion 5 enters the bearing recess 48d, so that the interposition portion 47 (hook) The movement of the body 4) in the crossing direction can be restricted. Further, the negative pressure state between the attached surface W and the suction surface S of the suction cup body 1 is increased, that is, the back peripheral edge of the suction cup body 1 is pressed by the pressing body 3, and the connecting rod 2 is moved. Thus, the suction cup body 1 can be maintained in an elastically deformed state.
[0065]
Further, a second sliding contact portion 48c formed continuously with the first sliding contact portion 48a is formed so that the radius of curvature R is constant and the center of curvature coincides with the axis of the shaft body 5 entering the bearing recess 48d. Therefore, even if the hook body 4 is rotated around the shaft body 5, the relative distance between the back surface of the pressing body 3 and the shaft body 5 can be kept constant. The pulling state with respect to can be kept constant. Thereby, even if the hook body 4 is rotated around the shaft body 5 due to the form of the suspended object, the attachment state to the attachment surface W can be maintained for a long time. Therefore, the hanging tool having the above-described configuration is not only used for attaching a small object or the like by attaching it to the attached surface, but for example, the hanging device having the above-described configuration is attached to each of the opposing wall surfaces (attached surface). It can also be used for applications such as stretching a rope.
[0066]
In addition, the hanging tool of this invention is not limited to said 2nd embodiment, Of course, a various change can be added in the range which does not deviate from the summary of this invention.
[0067]
In the above embodiment, the insertion holes 49 are formed in the connecting plates 45a and 45b to form the shaft sliding contact portion 48b on which the shaft body 5 slides. However, the present invention is not limited to this. Alternatively, the interposition part having the above-described configuration may be configured as a connecting plate, and the hook part 42 may be connected to the tapered one end part of the interposition part. That is, if the first sliding contact portion 48a, the second sliding contact portion 48c, the shaft sliding contact portion 48b, and the bearing concave portion 48d configured as described above are formed in the interposition portion 47, the back surface of the pressing body 3 and the shaft body 5 are formed. The second sliding contact portion 48c can be slidably contacted with the back surface of the pressing body 3 in a state where the shaft body 5 is accommodated in the bearing recess 48d. Similar actions and effects can be achieved.
[0068]
In the above embodiment, the shaft-sliding contact portion 48b is configured as a straight surface, but is not limited thereto, and may be, for example, an arc surface. However, as a matter of course, the arrangement of the one end and the other end of the second sliding portion 48c made of the circular arc surface is the same as that in the above embodiment.
[0069]
【The invention's effect】
As described above, according to the first aspect of the present invention, the suction cup body having flexibility and elasticity, the connecting rod projecting on the back surface of the suction cup body, and the pressing body in which the connecting rod is loosely inserted, A hook body that is connected to the connecting rod projecting on the back side of the pressing body and on which an object is hung, and relatively moving the pressing body and the connecting rod in the axial direction and in the separating direction, The pressing body is configured to press the back peripheral portion of the suction cup body, and the suction cup body is elastically deformed, and the suction cup body is an annular protrusion protruding toward the press body at the back peripheral portion. Because it is equipped with a part, even if it is in an attached state for a long period of time or repeatedly attached to and detached from the attached surface, it is surely prevented from flowing in air between the attached surface and the suction cup body Can do.
[0070]
Moreover, according to the invention concerning Claim 2, since the said recessed body is formed with the annular recessed part which carries out an uneven fitting with the said annular convex part, and this annular recessed part is comprised so that an annular convex part can be pressed, The annular convex portion can be prevented from being crushed unevenly, the suction cup body can be brought into close contact with the surface to be attached in a uniform state over the entire circumference, and stable suction can be realized.
