Shopping and like stacking trolley

摘要

A trolley 1 has a frame 3 and a front pair of castor wheels 9, and a rear pair of castor wheels 11 and a basket 5. A pivotally mounted arm 91 is movable between a locking position in which a portion of the arm engages a flat 101 on a castor shaft 85 and a second position in which the wheel is free to castor. A manual override is provided. The arm 91 is moved by another trolley nesting in the trolley, to a position in which the castor is free to swivel, thus allowing manoeuvrability when nested. When the nested trolley is removed the castor is locked again for steerability when used individually. Also disclosed are arrangements where one pair of the wheels are fixed axis and the other pair are castors. In this case when the trolleys are nested, the fixed axis wheels are lifted clear of the ground to provide manoeuvrability.
