Abstract (en)
A trolley control system for use in supermarkets and the like which includes an outlet (10) having normally retracted stops (30) closable on the approach of a trolley (28), a sensor (32) to sense a trolley (28) approach to prevent passage thereof, and retractable to open the outlet (10) and allow passage of the trolley on payment of a deposit. At the other end of the system is an inlet (18) to a reception area (20) for returned trolleys having a detector which initiates a refund of a deposit. Identification devices may be provided on the trolleys to effect validation of a trolley before a refund is made. A card system (in place of tokens or money) may be used and the cards may be so called charge-cards by which the deposit may be charged and then credited to a customers account. The outlet sensor may be optical so as to be responsive to a reflective device on a trolley and unresponsive to a person. Trolleys may be counted in and out.
