Abstract
An anti-theft parking system comprising a free-standing post at each delineated area for the parking of a single vehicle supporting audible and illuminated signals and a control circuit so designed that when a vehicle is driven into the area so as to depress a road switch set into the pavement of the area and a coin of appropriate value is deposited in a coin box, a key may be removed from a key switch without actuating the alarms, but if the vehicle is removed from the parking area so as to release the ground switch without restoring the key, the alarms will be actuated. There is a panel which becomes illuminated by parking the vehicle which indicates that a coin should be inserted and a panel which becomes illuminated by removal of the key which indicates that the system is conditioned for operation.
