The fence has support arms (4) which are pivotably located at on foot beams (5) running in recesses through the fence frame, and fixed to the ground plate (3). They are also pivotably attached to the fence frame upper part (6). The ground pledge is displaceably located on pins (11) running along a pair of bars (2B,2C). A lock device is fitted within the fence frame lower part (10) and works in conjunction with the foot beams to lock them both in the erected and lowered positions of the fence section. The frame side parts (24,25) support coupling components (20,22) for connection of fence sections. |
