Abstract

A vehicle barrier deployment system comprises a base member, at least two lifting members, at least one barrier member, and an actuation assembly. The lifting members are pivotally secured to the base member, and are operable to be selectively raised and lowered in a vertical direction relative to the base member. The at least one barrier member is in communication with the lifting members, and is configured to stop a moving vehicle when the lifting members are in a raised position. The actuation assembly is in communication with the lifting members, and is operable to selectively raise and lower the lifting members by moving at least a portion of each of the lifting members in a direction transverse to a traffic lane. The barrier member may comprise chains, a guardrail, or other structures. The system may be mobile or may be fixed (e.g., embedded in ground) in a particular location.

Claims

1. A vehicle barrier deployment system, comprising:

(a) a base member, wherein the base member is recessed below a road surface;

(b) at least two lifting members pivotally secured to the base member, wherein the at least two lifting members are operable to be selectively raised and lowered in a vertical direction relative to the base member, wherein the at least two lifting members are located below the road surface when the at least two lifting members are in a lowered position;

(c) at least one barrier member non-resiliently secured relative to the ground, wherein the at least one barrier member is in communication with the at least two lifting members, wherein the at least one barrier member is selected from the group consisting of cables and chains, wherein the at least one barrier member is configured to stop a moving vehicle when the at least two lifting members are in a raised position, wherein the at least one barrier member is located below the road surface when the at least two lifting members are in the lowered position; and

(d) an actuation assembly in communication with the at least two lifting members, wherein the actuation assembly is operable to selectively raise and lower the at least two lifting members by moving at least a portion of each of the at least two lifting members in a direction that is transverse to a traffic lane.

2. The vehicle barrier deployment system of claim 1, wherein each of the at least two lifting members comprise a folding deployment post, wherein the folding deployment post comprises an upper portion and a lower portion, wherein the upper portion is configured to pivot relative to the lower portion.

3. The vehicle barrier deployment system of claim 2, wherein the lower portion of each folding deployment post is pivotally secured to the base member.

4. The vehicle barrier deployment system of claim 3, wherein the lower portion of each folding deployment post is pivotally secured to the base member by a corresponding shear bearing joint.

5. The vehicle barrier deployment system of claim 4, wherein at least a portion of each shear bearing joint is configured to break upon impact of a moving vehicle with at least one of the at least two lifting members or the at least one barrier member.

6. The vehicle barrier deployment system of claim 2, wherein the upper portion of each deployment post is in pivotal engagement with the at least one barrier member.

7. The vehicle barrier deployment system of claim 1, wherein each of the at least two lifting members comprises a plurality of slots, wherein each of the slots is configured to receive a portion of a corresponding chain of the plurality of chains.

8. The vehicle barrier deployment system of claim 1, wherein the actuation assembly comprises a winch and a cable, wherein the cable is in communication with the at least two lifting members.

9. The vehicle barrier deployment system of claim 8, further comprising at least one pulley, wherein the pulley is positioned along the cable between the winch and at least one of the at least two lifting members.

10. The vehicle barrier deployment system of claim 8, wherein the winch is operable to actively raise the at least two lifting members when the winch is rotated in a first direction, wherein the winch is operable to actively lower the at least two lifting members when the winch is rotated in a second direction.

11. The vehicle barrier deployment system of claim 1, further comprising a housing, wherein the housing is configured to be embedded within the ground.

12. The vehicle barrier deployment system of claim 11, further comprising a cover plate, wherein the cover plate is configured to selectively cover the at least two lifting members and the at least one barrier member when the at least two lifting members are lowered within the housing.

13. The vehicle barrier deployment system of claim 12, wherein the cover plate is configured to rotate relative to the housing along a first plane of rotation, wherein each of the at least two lifting members is configured to rotate relative to the base member along a second plane of rotation, wherein the second plane of rotation is perpendicular to the first plane of rotation.

14. A vehicle barrier deployment system, comprising:

(a) a base member, wherein the base member defines a longitudinal plane that is perpendicular to the ground, wherein the base member is recessed below the ground surface;

(b) at least two lifting members pivotally secured to the base member, wherein the at least two lifting members are operable to be selectively raised and lowered in a vertical direction relative to the base member;

(c) at least one barrier member, wherein the at least one barrier member is selected from the group consisting of chains and cables, wherein the at least one barrier member is in communication with the at least two lifting members, wherein the at least one barrier member is configured to non-resiliently stop a moving vehicle when the at least two lifting members are in a raised position, wherein the at least one barrier member is positioned below the ground surface when the at least two lifting members are in a lowered position; and

(d) an actuation assembly in communication with the at least two lifting members, wherein the actuation assembly is operable to selectively raise and lower the at least two lifting members by causing at least a portion of each of the at least two lifting members to sweep along the longitudinal plane perpendicular to the ground.

15. A method of providing a vehicle barrier across at least one lane of a roadway, the roadway having a surface, the method comprising:

(a) providing a pair of pivoting lifting members, wherein each of the pivoting lifting members are oriented in a direction transverse to the path of vehicles traveling along a lane of a roadway, wherein the pivoting lifting members are positioned below the surface of the roadway;

(b) providing at least one barrier member in communication with the pair of pivoting lifting members, wherein the at least one barrier member spans across the width of at least one lane of the roadway, wherein the at least one barrier member is selected from the group consisting of cables and chains, wherein the at least one barrier member is positioned below the surface of the roadway;

(c) providing an actuation assembly in communication with the pair of lifting members, wherein the actuation assembly is operable to cause the pair of pivoting members to pivot, to thereby raise the at least one barrier member relative to the ground; and

(d) activating the actuation assembly to pivot the pair of pivoting members relative to the ground, thereby raising the at least one barrier member relative to the ground, wherein the act of activating the actuation assembly comprises;

(i) raising a portion of the pivoting lifting members above the roadway surface, and

(ii) raising the at least one barrier member above the roadway surface.
