ABSTRACT:
Apparatus for controlling access to a parking space which may utilize either a vehicle body or a tire access blocking barrier. In one embodiment a barrier is pivotally mounted on a parking space floor for movement between an upwardly extending and horizontal position. The barrier is held upright by a spring biased locking pin, which is retracted by a remote control by a vehicle driver to allow the barrier to fall to the horizontal position. Spaced forward and rear plates are pivotally mounted on the space floor and are connected by a bell crank linkage. So, when one plate is pivoted to the floor by a vehicle wheel driving over it, the other plate is pivoted to an upright position. A latch member is carried by the front plate which engages the barrier as the front plte is pivoted to the floor by wheel contact. The front plate and the engaged barrier are pivoted to an upright position when the vehicle backs out and pivots the rear plate to the floor.
