DOOR OPENING ASSISTING DEVICE AND METHOD OF USING DOOR OPENING ASSISTING DEVICE

To provide a door opening assisting device with a simple structure, capable of reducing an initial opening force in opening a door.SOLUTION: The door opening assisting device comprises: a door side member attached to a door supported in a frame part provided in an opening part of a wall part so as to allow opening/closing of the opening part; and a pressing device attached to either a structure surrounding the frame part or the frame part, which presses the door side member towards an opening side. The door side member has a pressed part provided nearer to a door end than the door and positioned nearer to an opening side in a depth direction than the door. The pressing device includes: an opposing part positioned nearer to a closing side of the door than the pressed part, opposing the pressed part in the depth direction; an operation part connected to the door end side of the opposing part and exposed towards the opening side in the depth direction; and a conversion part that converts a force applied to the operation part in a direction different from the opening side in the depth direction, to a force in the direction in which the opposing part moves towards the opening side in the depth direction.SELECTED DRAWING: Figure 3 【課題】簡単な構造でドアの開放における初期の開放力を軽減できるドア開放アシスト装置を提供する。【解決手段】壁部の開口部に設けられた枠部に、開口部を開閉可能に支持されたドアに取り付けられたドア側部材と、枠部を囲む構造体及び枠部の何れかに取り付けられ、ドア側部材を開放側に押圧する押圧装置と、を備える。ドア側部材は、ドアよりも戸先側に配置されドアよりも見込み方向の開放側に位置する被押圧部を有する。押圧装置は、被押圧部よりもドアの閉塞側に位置し見込み方向で被押圧部と対向する対向部と、対向部の戸先側に連結され、見込み方向の開放側に露出する操作部と、操作部に加わる見込み方向の開放側とは異なる向きの力を、対向部が見込み方向の開放側に向かう方向の力に変換する変換部と、を有する。【選択図】図３
