The present invention relates to a release prevention apparatus for an elevator door. The elease prevention apparatus for an elevator door guides a elevator door through guide grooves of a door seal unit arranged on the riding platform of an elevation path connecting the elevation spaces of the elevator moving therein in a spatial manner, moves in a linear path in a reciprocating manner, and opens or closes the riding platform in order to prevent accidents by preventing the elevator door from being released from the elevation path due to an impact applied to the elevator door from the riding platform. The elevator door includes a door shoe unit moving in a linear path in a reciprocating manner while having the lower end stored in the guide grooves while additionally including a plate-shaped reinforcement means including a storage piece being inserted and stored in the guide grooves as well as being coupled to the door shoe. The reinforcement means is a plate body made of metal materials. The storage piece has elastic protrusion units formed to be curved in a direction toward the elevation spaces of the elevator moving therein from the inside of the guide grooves in order to generate an elastic force in the connection parts with the storage piece.
본 발명은, 승강장에서 승강기 도어로 인가되는 충격하중에 의한 도어의 이탈을 방지하여 안전사고를 방지할 수 있도록; 승강기가 승강하는 승강공간을 공간적으로 연결하는 승강통로의 탑승구에 배치된 도어씰의 가이드홈을 안내하면서 직선 왕복 운동하여 탑승구를 개폐하도록 된 승강기 도어의 대한 이탈을 방지하도록 된 승강기 도어의 이탈방지장치에 있어서; 상기한 도어에는, 상기 가이드홈에 하단이 수용된 상태에서 직선왕복운동하도록 된 도어슈가 구비되며; 상기한 도어슈에 결합되며 상기 가이드홈의 내부로 삽입수용되는 수용편을 가지는 '판' 형상의 보강수단을 더 포함하여 이루어지되; 상기 보강수단은, 금속재질로 형성된 '판' 형상의 판체로 이루어지며; 상기한 수용편에는, 상기 가이드홈의 내부에서 승강기가 승강하는 승강공간측 방향으로 절곡되어 연장형성되어 상기 수용편과의 연결부위에 탄성력을 형성하도록 된 탄성돌부가 구비된 승강기 도어의 이탈방지장치를 제공한다.
