DOOR GUARD WITH LOCK FUNCTION
PROBLEM TO BE SOLVED: To provide a door guard with a lock function that can lock a door as a simple auxiliary means.SOLUTION: A door guard has an arm member 1 and a receiver 2. The arm member 1 has an arm 13. The receiver 2 has a bearing 23. An insertion and extraction hole 14 and a slide hole 15 are formed on the arm 13. The receiver 2 has not only the bearing 23 but also a lever-like lock switch 24 that can be switched between a projection position and a retreat position along with rotation. When the arm 13 is raised and the lock switch 24 is switched to the projection position in a state where the door D is closed, the lock switch 24 is inserted in the insertion and extraction hole 14. If someone tries to open the door D in this state, the lock switch 24 butts against a base end step part 16 on a border between the insertion and extraction hole 14 and the slide hole 15, which causes the lock state in which the door D is prevented from opening. When the lock switch 24 is switched to the retreat position, the door D gets to a restriction sate in which the opening of the door D is restricted to a certain range or a freely openable or closable state depending on inclination of the arm 13.SELECTED DRAWING: Figure 4
【課題】簡易な補助的戸締りが可能なロック機能を有するドアガードを提供する。【解決手段】アーム部材１と受具２とから成り、アーム部材１にはアーム１３を備え、受具２には受軸２３を備え、アーム１３に挿脱穴１４及びスライド穴１５を形成したドアガードにおいて、受具２には、受軸２３に加えて、回動に伴い突出位置と退入位置とに切り替えられるレバー状のロックスイッチ２４を備える。ドアＤを閉じた状態でアーム１３を起立させ、ロックスイッチ２４を突出位置とすると、ロックスイッチ２４が挿脱穴１４に挿入され、その状態でドアＤを開こうとすると、ロックスイッチ２４が挿脱穴１４とスライド穴１５の境界の基端段部１６に当接して、ドアＤの開きが阻止されるロック状態となり、ロックスイッチ２４を退入位置とすると、アーム１３の起倒に応じて、ドアＤが一定範囲の開度に制限される用心状態又は自由に開閉可能な状態となる。【選択図】図４
