GAP RETAINER FOR DOOR
PROBLEM TO BE SOLVED: To provide a cheap tool for housing environmental improvement with a simpler operation, while taking crime prevention measures by a conventional door chain and a door bar.SOLUTION: In a door 1, a door chain 4 or a door bar 5 is provided between the door 1 and a door frame 2, a door open gap is limited to a maximum W and the door is receiving force in a closing direction by a door closer 3. A holding member 6a is fixed to the door 1, and a stopper member 6b which is made to be length L shorter than W, which suspends by self-weight and which can rotate is mounted on the holding member 6a. When the door 1 is opened and the suspending stopper member 6b is arranged between the door 1 and the door frame 2 manually, the stopper member is sandwiched between the door and the door frame naturally with the force of the door closer 3, and the gap is retained. For release, when the door is opened to the opening direction, the stopper member moves to the suspension direction by self-weight.SELECTED DRAWING: Figure 1
【課題】従来のドアチェーン、ドアバーで防犯対策を取りながら、より簡単操作で安価な住環境改善用具を提供する。【解決手段】ドア１とドア枠２間にドアチェーン４又はドアバー５が設けられ、ドア開放隙間が最大Ｗに制限されていると共にドアクローザー３で閉じる方向に力を受けているドア１に対して、ドア１に保持部材６ａを固着し、保持部材６ａにＷより短い長さＬで作られ、自重で垂下し、回動可能なストッパー部材６ｂを取り付ける。ドア１を開け、垂下しているストッパー部材６ｂをドア１とドア枠２間に手で配置すると、ドアクローザー３の力で自然とドアとドア枠間に挟まれ、隙間が保持され、解除はドアを開く方向へ動かせば自重でストッパー部材は垂下方向へ移動する。【選択図】図１
