IMPROVEMENTS IN OR RELATING TO SELF-WINDING REEL ASSEMBLIES

摘要

A self-winding reel assembly comprises a spool (18) rotatably mounted, within a housing (10), around a fixed shaft (17). A flexible belt (32) wound around the spool is provided on its free end with a catch device (34) for connection to a retainer when the belt is unwound from the spool to form a temporary barrier. The spool (18) is driven by a clock spring (25) which is located in a space (24) within the spool (18) itself. An adjustable cam device (29) rotates with the spool to operate a micro switch (30) controlling an electric alarm device (31). Rotation of the spool (18) may be controlled by an air brake or inertia brake.
