ーン巻上式開閉ドアの安全装置。[Scope of claim for utility model registration] A door body that fits into the guide rails on both sides,
sprockets on both sides that can be rotated in forward and reverse directions by an electric opening/closing machine; a hoisting chain that is wound around each of these sprockets and has one end connected to the door body and the other end connected to a weight;
A chain hoisting type opening/closing door consisting of chain guides on both sides that guide the vertical movement of the weight, further comprising: a connecting member that engages the other end of the hoisting chain and the weight so that the two can be separated by a predetermined tensile force or more; , a regulating protrusion provided on the chain guide that exceeds the set upper limit height of the weight and that locks the weight and releases the weight from the hoisting chain when the weight is moved upward beyond this height, and a regulating protrusion that is provided on the chain guide that exceeds the set upper limit height of the weight; A safety device for a chain hoisting type opening/closing door, characterized in that a detector is provided at the bottom of the guide to detect the presence of a weight and stop the operation of an electric opening/closing machine.
