Patent Images
1. A deployable vehicle barricade apparatus for resisting and absorbing vehicular impact comprising:
- (a) an elongate rigid post having two ends, a top end and bottom end;
(b) elongate rigid tubular casing means for receiving said post, said casing means having an inner surface and an outer surface;
(c) propellant means for rapidly causing an upper portion of said post proximate said top end to extend beyond said casing means;
(d) brace means cooperating between said post and said inner surface of said tubular casing means for resisting and transferring the force of a vehicular impact upon said upper portion of said post to said casing means; and
(e) said brace means including at least two spaced-apart brace elements, each of said brace elements cooperating between said post and said inner surface of said casing means to transfer said force to said casing means, said brace elements spaced apart a distance greater than one-half the length of said post.

Abstract
A deployable vehicular barricade system includes a plurality of barricade units each having an elongate rigid post slidably received in a below-grade casing. Longitudinally spaced guide plates cooperating between the post and the casing guide the post between an extended position partially projecting from the casing and a retracted position within the casing and also serve to resist vehicular impact to the post in the extended position. A spring in the bottom of the casing and a remotely controlled locking arm and trigger mechanism allow the post to be selectively and instantaneously deployed into the extended position.
