ABSTRACT:
A vehicle barrier includes a barrier plate pivotally attached to a base support for movement between a horizontal non-operative position and an angularly operative position, a brace extending rearwardly from a pivotal support secured to a rear surface of the barrier plate and spaced from a barrier pivot disposed on a front of the base support, a brace stop device mounted on a rear of the base support, and operating mechanisms for raising and lowering the barrier gate and associated brace from horizontal non-operative positions to angularly operative positions and vice-versa. When the barrier plate is in its angularly operative position, a rear end of the brace abuts the brace stop device so that the brace is in an inclined position. The brace lies in a substantially horizontal plane and is out of engagement with the brace stop device when the barrier gate is in its horizontal non-operative position.
