SWITCHING BODY STOPPING DEVICE FOR SWITCHGEAR
PROBLEM TO BE SOLVED: To provide a switching body stopping device for a switchgear capable of preventing a load coupling the switching body and a string-like member from iteratively acting on the same part of a member forming a mechanical coupling device or on the same part of the string-like member each time the switching body reaches a full closing position.SOLUTION: A shutter curtain 1 that is a switching body includes a master curtain part 71A and a sub curtain part 71B. The switching body stopping device includes the mechanical coupling device which makes a tensile force caused by a dead weight of the shutter curtain act on the string-like member by mechanically coupling the shutter curtain and the string-like member when the master curtain part moves to a closing side by abutting the sub curtain part that reaches a movement limit position of the closing side with respect to the master curtain part, to an obstacle during closing movement of the shutter curtain. The switching body stopping device also includes means 400 for preventing the master curtain part from moving to the closing side when the sub curtain part is moved to a full closing position or a substantially full closing position by the closing movement of the shutter curtain.
【課題】開閉体が全閉位置に達するごとに、機械式結合装置を構成する部材の同じ箇所や紐状部材の同じ箇所に、開閉体と紐状部材とを結合させる荷重が繰り返し作用することを解消できる開閉装置の開閉体停止装置を提供すること。【解決手段】開閉体であるシャッターカーテン１は、カーテン主部７１Ａとカーテン副部７１Ｂとを含んで構成され、本装置は、シャッターカーテンの閉じ移動中に、カーテン主部に対して閉じ側の移動限位置に達しているカーテン副部が障害物に当接することでカーテン主部が閉じ側へ移動したときに、シャッターカーテンと紐状部材とを機械式に結合することでこの紐状部材にシャッターカーテンの自重による緊張力を作用させる機械式結合装置を有し、また、シャッターカーテンの閉じ移動によりカーテン副部が全閉位置又は略全閉位置まで移動したときに、カーテン主部が閉じ側へ移動することを阻止する手段４００を備えている。【選択図】図１４
