Abstract

Abstract A self-enforcing parking system is disclosed herein wherein the motorist must deposit the proper monetary amount in a meter before he can remove his vehicle from the parking stall. The stall comprises a flat plate having wheel guides thereon which aid in properly positioning the front wheels of the vehicle as it is driven into the stall. A front curb is positioned at the forward end of the stall to position the vehicle front wheels on a pair of pressure pads having normally open switches therein. A pair of barrier plates, driven by a hydraulic cylinder means, pivotally move upwardly behind the vehicle front wheels after the vehicle is properly positioned on the pressure pads. When the motorist desires to leave the parking stall, he must deposit the proper amount of coins in the meter to cause the barrier plates to be lowered by the hydraulic cylinder means. The parking charges are directly indicated on the meter to indicate the fee which must be paid.
