Scaffolding railing and its fastening device

摘要

The railing (4) comprises two horizontal tubes (6) at the ends of which are two perpendicular tubular gudgeons (7) in each of which are engaged in a tubular socket (3) carried by a scaffolding post. Each gudgeon is a trapezoidal pawl (13) which slides in a lateral slot (12) and is subjected to the action of a U-shaped leaf spring (14) housed inside the gudgeon. The pawl can occupy a stable locking position and a stable unlocking position enabling the withdrawal of the railing by a single operator.
