    摘要: A manually operated traffic barrier gate which may economically installed and maintained, and easily operated by a single individual during emergency or other critical situations. One embodiment comprises a permanently mounted barrier gate movable from a retracted, upright position to lowered position extended to bridge a preselected traffic path, wherein the gate is counterbalanced to stay in the upright position until deployed, and to be balanced to stay in the deployed state when extended. The barrier gate are operable by one person and includes locking devices to maintain their stored upright or deployed lowered position. A further embodiment of the present invention provides a dual mobile gate which may be towed singly or in a chain (dual gate one behind the other), in a retracted length to the desired location, and thereafter be disconnected from the towing vehicle and left at the site to be deployed in an extended manner or retracted and moved as needed.

    摘要: A retractable gate comprising a movable arm gate having multiple sections which nest or telescope into each other when parked (e.g. upright), and extends into a full length blocking position as it is deployed. The gate arm sections are deployed by the movement of one of the arms, e.g. the outer one section, relative to the ground or a stationary support member and is joined to the stationary support member by a pivot point or bearing, and is connected to the stationary support or ground by a cable connection (or equivalent) which powers the arm sections into extended or retracted positions by movement of the gate about the pivot bearing. A novel corresponding counterweight system provides selectable balance and torque requirements.
