Claims

[Scope of utility model registration request]

This is a reverse warpage prevention device with a link mechanism used in the top panel of an overhead door.As shown in Fig. 4, a guide arm 3, a spring 17, and a link arm are attached to the top panel 1 between the upper bracket 6 and the lower bracket 2. A4, the link arm B5 is movably connected, and the roller 10 is guided by the guide rail 11 to the guide arm 3.
is attached to the guide arm 3, and a lateral rod 7 extending from the bracket 8 of the middle crosspiece 9 is also attached to the guide arm 3. Place the stopper 16 on the guide rail 1 at a position where the link mechanism operates so that the panel is aligned in a straight line when the panel is lowered.
A device to prevent reverse warping of the overhead door installed in 1.
