DOOR GUARD WITH LOCK FUNCTION
PROBLEM TO BE SOLVED: To provide a door guard with a lock function that can lock a door as an effective auxiliary means while reducing costs.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. A lever-like lock switch 16, which can be switched between a pull-out position and a push-in position along with rotation, is installed on the arm member 1. A hook part 17 is formed on a tip side of the lock switch 16. If someone tries to open the door D by switching the lock switch 16 to the push-in position, inclined planes 18, 24 of the hook part 17 and the bearing 23 butt against each other and slide, which causes a butting face 19 of the arm 13 to butt against a receiving face 25 of the bearing 23, resulting in the lock state in which the door D is prevented from opening. As the tensile force to open the door does not work on the lock switch 16, inexpensive resin material can be used.SELECTED DRAWING: Figure 6
【課題】コストを抑制しつつ、有効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、アーム部材１には、回動に伴い引出位置と押込位置とに切り替えられるレバー状のロックスイッチ１６を備え、ロックスイッチ１６の先端側にフック部１７を形成する。ロックスイッチ１６を押込位置としてドアＤを開こうとすると、フック部１７と受軸２３の傾斜面１８，２４同士が当接して摺動し、アーム１３の突当面１９が受軸２３の受止面２５に当接して、ドアＤの開きが阻止されるロック状態となる。ロックスイッチ１６には、ドアを開こうとする引張力が作用しないので、安価な樹脂材料を使用できる。【選択図】図６
