摘要：
A barrier comprises a relatively fixed lower section (14), and an upper section (15) which is movable between relatively raised and lowered positions.
The upper section (15) is preferably pivotable between its relatively raised and lowered positions, and the upper section (15) or a substantial part thereof is preferably made of see-through material, such as a mesh or transparent plate.
In use, the upper section (15) may normally occupy its relatively lowered position and means (16) is provided for moving the upper section (15) to its relatively raised position.
