Abstract: An improved barrier assembly for selectively preventing and allowing travel along a path includes a frame assembly situated beside the path, at least one elongated barrier arm having a blocking position projecting laterally from the frame assembly across the path for preventing travel past the barrier arm along the path when the barrier arm is in the blocking position, and a connecting assembly connecting the barrier arm to the frame assembly for swinging movement with respect thereto about a substantially horizontal axis between the blocking position extending across the path and a non-blocking position wherein the barrier arm extends substantially vertically along the frame assembly to be situated with the latter beside the path to permit travel therealong. According to the invention the frame assembly comprises a channel enclosure to which a barrier arm is connected by the connecting means, the channel enclosure being constituted by a member having a substantially C-shaped cross-section.

Abstract: A vehicle barrier of the type which will temporarily prevent an unauthorized vehicle from entering a given parking space or from passing through the entrance to any given area. An upright support is situated beside the path along which a vehicle will normally travel, and an elongated barrier arm has a blocking position extending laterally from the upright support across the path which otherwise would be travelled by the vehicle so as to prevent the latter from travelling along this path.
