To provide a guide shoe capable of removing removable foreign matters with a normal extrusive force during foreign matter mixing and capable of avoiding non-moving foreign matters during door-opening/closing to prevent a door-opening/-closing defect caused by foreign matters such as pebbles mixed in an elevator sill groove.SOLUTION: A guide shoe 50 comprises a rotating shaft 34 fixed to a door panel 32 moving along a prescribed path with a groove of a slide-type door, a first spring engaging with an outer circumference of the rotating shaft 34, and a guide member 51 to be inserted at the end of the rotating shaft 34 engaging with the first spring through a through hole, to be engaged in the groove, and to guide the door panel 32. The first spring generates an energizing force when the guide member 51 comes into contact with a foreign matter 42 in the groove at the operating time of the door panel 32. As a result, the door panel 32 continues a predetermined slide operation when the residual force of the foreign matter 42 is large. The guide member 51 rotates with respect to the rotating shaft 34, and thereafter, the guide member 51 is restored to the initial position of the door panel 32.SELECTED DRAWING: Figure 8
【課題】エレベータのシル溝に小石等の異物が混入すると、ドア開閉に不具合が生じる。そこで、異物混入時、除去可能な異物は通常の押し出し力で除去し、動かない異物はドア開閉時、回避可能としたガイドシューを提供する。【解決手段】ガイドシュー50は、スライド式ドアの、溝部を有する所定経路に沿い移動するドアパネル32に固設される回転軸34と、回転軸34外周に係合する第一のバネと、貫通孔を介し第一のバネを係合した回転軸34一端部に挿通し、溝部に係入してドアパネル32を案内する案内部材51と、を具備するドアガイドシュー50であって、第一のバネは、ドアパネル32動作時に、溝部内の異物42に案内部材51が接触すると付勢力を生じ、それより異物42の残留する力が大きい時に、ドアパネル32は所定のスライド動作を継続し、回転軸34を基点として案内部材51が回転し、その後案内部材51はドアパネル32の初期位置に復元する。【選択図】図8
