PROBLEM TO BE SOLVED: To prevent an infant from turning a knob-type door knob in an opening direction, without the need for drilling of a hole in a door and adhesion to the door.SOLUTION: A door knob cover of the present invention is used as a joint body by making a plurality of components cover a door knob and joining them together. In the joint body, finger holes are opened in opposing two locations in a cylindrical or square cylinder-shaped cylinder part, and a front surface serves as a blind end. Since the cylinder part has a large outside diameter, the size of an infant's single hand disables him/her from gripping the door knob by simultaneously inserting his/her two finders, and disables him/her from turning the door knob.
【課題】ドアに穿孔や接着を必要とせずに握り玉タイプのドアノブを幼児が開けることができないようにすることを目的とする。【解決手段】本発明のドアノブカバーは複数の部品をドアノブにかぶせて接合して接合体として使用する．接合体は円筒形もしくは四角筒形の筒部に対面の二カ所に指穴が開いており前面は盲端になっている．筒部の外径は大きいため幼児の片手の大きさでは指を二本同時に入れてドアノブを把持することはできず，ドアノブを回せなくなる．【選択図】図３
