Abstract

A barrier system comprises a housing, substantially vertical members, and vertical guide tubes. The housing extends into the ground. The guide tubes are positioned in the housing and also extend into the ground below the housing. The substantially vertical members are translatable vertically within the guide tubes. At least one barrier member is secured to the substantially vertical members. The at least one barrier member may comprise at least one guardrail, a plurality of chains or cables, and/or a plurality of gate beams. A series of cables and pulleys form an actuation system that raises and lowers the substantially vertical members relative to the guide tubes to selectively extend and retract the at least one barrier member relative to the ground. A cover plate may selectively cover the top opening of the housing when the barrier member and substantially vertical members are retracted within the housing.

Claims

1. A vehicle barrier system, comprising:

(a) a housing;

(b) a plurality of substantially vertical members;

(c) a plurality of substantially vertical guides, wherein the substantially vertical guides are secured relative to the housing, wherein the substantially vertical members are translatable relative to the substantially vertical guides;

(d) at least one barrier member coupled with the substantially vertical members, wherein the at least one barrier member is configured to stop a moving vehicle when the substantially vertical members are in a raised position relative to the housing; and

(e) an actuation assembly in communication with the substantially vertical members, wherein the actuation assembly comprises a rotatable drive member in communication with a movable drive member, wherein the actuation assembly is operable to actuate the rotatable drive member in a first angular direction pull the drive member in a first linear direction to lift the substantially vertical members to a raised position relative to the housing to selectively deploy the at least one barrier member, wherein the actuation assembly is further operable to actuate the rotatable drive member in a second angular direction to pull the drive member in a second linear direction to lower the substantially vertical members to a lowered position relative to the housing to selectively retract the at least one barrier member, wherein the at least one barrier member is retracted within the housing when the vertical members are in the lowered position relative to the housing.

2. The vehicle barrier system of claim 1, wherein the actuation assembly comprises a first pulley secured to the housing and a first cable engaged with the first pulley.

3. The vehicle barrier system of claim 2, wherein the first cable is further engaged with a first substantially vertical member of the plurality of substantially vertical members to raise the first substantially vertical member relative to the housing.

4. The vehicle barrier system of claim 3, wherein the actuation assembly further comprises a second pulley secured to the housing and a second cable engaged with the second pulley, wherein the second cable is further secured relative to the first substantially vertical member to lower the first substantially vertical member relative to the housing, wherein the first and second cables together form the movable drive member.

5. The vehicle barrier system of claim 4, wherein the rotatable drive member comprises a winch, wherein the winch is operable to selectively pull the first cable relative to the winch while simultaneously releasing the second cable relative to the winch, wherein the winch is further operable to selectively pull the second cable relative to the winch while simultaneously releasing the first cable relative to the winch.

6. The vehicle barrier system of claim 1, further comprising a substantially horizontal member, wherein each substantially vertical member of the plurality of substantially vertical members includes a respective top portion, wherein the substantially horizontal member is secured to the top portions of the substantially vertical members.

7. The vehicle barrier system of claim 1, further comprising at least one cover plate coupled with the housing, wherein the at least one cover plate is rotatable relative to the housing to selectively enclose the substantially vertical members and the at least one barrier member within the housing when the substantially vertical members are in the lowered position.

8. The vehicle barrier system of claim 1, wherein the at least one barrier member comprises a guardrail.

9. A vehicle barrier system, comprising:

(a) a housing;

(b) a plurality of substantially vertical members;

(c) a plurality of substantially vertical guides, wherein the substantially vertical guides are secured relative to the housing, wherein the substantially vertical members are translatable relative to the substantially vertical guides;

(d) at least one barrier member coupled with the substantially vertical members, wherein the at least one barrier member is configured to stop a moving vehicle when the substantially vertical members are in a raised position relative to the housing; and

(e) a plurality of cables and pulleys, wherein the cables are coupled with at least one of the substantially vertical members, wherein a first cable of the plurality of cables is fed through a space defined between a first substantially vertical member of the plurality of vertical members and a first substantially vertical guide tube of the plurality of substantially vertical guide tubes, wherein the first cable is operable to selectively raise the first substantially vertical member relative to the housing, wherein the at least one barrier member is retracted within the housing when the vertical members are in a lowered position relative to the housing, wherein at least one of the cables is operable to actively pull at least one of the substantially vertical members from the raised position to a retracted position.
