Claims

[Scope of utility model registration request]

In a foldable fence body in which the side ends of unit frames are sequentially connected, two pin shafts are erected at appropriate positions on the side ends of the unit frames, and are arranged to intersect horizontally in an X-shape. One end of the two link fittings is rotatably fixed to the two pin shafts, respectively,
The other ends of the link fittings are each rotatably fixed to two pin shafts set upright at the side ends of adjacent unit frames,
When the fence body is extended, the action intersection of the link fittings crossed horizontally in an X shape is
A freely foldable fence body characterized by shifting its position in the bending direction.
