Abstract
Abstract A security device for selectively blocking a parking space to prevent unauthorized use of the space. Stationary vertical support means set into the pavement of ground outside and adjacent to the parking space and a moveable barrier portion is pivotally secured to the support means so as to be swingable from an upper, vertical position in which the space is free for use by a vehicle, to a lower, horizontal position in which the barrier portion extends across a substantial portion of the parking space and blocks use thereof. Locking means may be provided to lock the barrier in either horizontal or vertical positions, or both, to prevent unauthorized moving thereof.
