Abstract
A vehicle access control device having vertically-disposed tire-piercing spears. An upwardly spring-biased tent-like covering over the spears protects pedestrians, the covering being movable between a lower position in which the spears are exposed and an upper position in which the spears are covered. The weight of a pedestrian is insufficient to force the covering from the upper position to the lower position but the weight of a car is sufficient to do so. A remotely-controlled horizontally-movable plate selectively enables and disables the tent-like covering to lower under the weight of a car. The plate and the covering both have windows to allow the spears to pass therethrough when the covering is lowered, the plate blocking the windows in the covering when the lowering of the covering is disabled. The device is surface-mountable on a roadway without the need for digging into the roadway.
