Abstract

A trolley wheel mechanism (1) has two caster wheel assemblies (2) each having a pair of wheels (15) mounted on a rotatable housing (18). In a free mode the wheels (15) are free to both rotate and to swivel. This is caused by the user pressing a release pedal (4). In a unidirectional mode a retainer lock (19) engages a brake disc (22) to prevent swivelling of the housing (18). This is caused by the user pressing both pedals (4, 5) simultaneously. A brake mode is caused by the user pressing the apply pedal (5).
