发明名称 ELEVATOR DOOR REPAIRING DEVICE
摘要 PROBLEM TO BE SOLVED: To temporarily repair a bending damage of any door by detaching a door panel when the door panel is bent, abutting a support frame on a recess- bent part side of the door panel, abutting a pressure applying part on a projecting-bent part of the bent door panel, sandwiching the bent door panel with both parts, and applying the pressure by a pressure applying means to press back the bent part. SOLUTION: A support frame 2 is abutted on a recess-bent part side of a bent door panel 1, a pressure applying part 3 is abutted on a projecting-bent part, and the bent door panel 1 is sandwiched with the support frame 2 and the pressure applying part 3. The pressure is applied to the support frame 2 and the pressure applying part 3 by a pressure applying means 4 to return a bent part of the bent door panel 1 to the original. At least one of a long side and a short side of the support frame 2 is of adjustable rectangular shape. The length of the pressure applying part 3 is a rod-like body of U-shaped section which is not shorter than the short side of the bent door panel 1, and the pressure applying means 4 is preferably either a screw-type device or a pressure device.
