To provide a protection device of an elevator doorway with a protection plate, a supporting member, an upper screw member, and a lower screw member, and capable of easily attaching/detaching the protection plate to/from the supporting member.SOLUTION: A protection device of an elevator doorway comprises a protection plate with a top edge penetration part and a bottom edge penetration part, a supporting member with multiple screw holes, an upper screw member, and a lower screw member. The top edge penetration part is indented from the top edge of the protection plate toward the downward direction, and the bottom edge penetration part is indented from the bottom edge of the protection plate toward the upward direction. The upper screw part is passed through the top edge penetration part and is screwed in a screw hole, and the lower screw member is passed through the bottom edge penetration part and is screwed in a screw hole. The lower screw member comes off the bottom edge penetration part when the protection plate is moved upward, and the upper screw member does not come off the top edge penetration part even when the protection plate is moved downward.SELECTED DRAWING: Figure 9
【課題】保護板、支持部材、上部ねじ部材及び下部ねじ部材を備え、保護板を支持部材に容易に着脱することができるエレベータの出入口保護装置を提供する。【解決手段】上端貫通部及び下端貫通部を有する保護板と、複数のねじ穴を有する支持部材と、上部ねじ部材と、下部ねじ部材とを備え、上端貫通部は保護板の上端から下方に窪み、下端貫通部は保護板の下端から上方に窪み、上部ねじ部材は上端貫通部に通されてねじ穴にねじ込まれ、下部ねじ部材は下端貫通部に通されてねじ穴にねじ込まれ、保護板を上方に移動させると下部ねじ部材が下端貫通部から外れ、保護板を下方に移動させても上部ねじ部材が上端貫通部から外れない。【選択図】図9
