Abstract

A vehicle mitigation system a barrier hauler and at least one barrier. The barrier hauler includes a stem, a handle positioned at one end of the stem, and at least one wheel positioned near an opposite end of the stem, the wheel capable of rotating relative to the stem. The barrier hauler further includes a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem. The barrier includes at least one wheel positioned at a first end of the barrier to act in cooperation with the at least one wheel of the barrier hauler when the barrier hauler is engaged with the barrier.

Claims (65)

1 . A vehicle mitigation system comprising:

a barrier hauler comprising:

a stem;

a handle positioned at one end of the stem;

at least one wheel positioned near an opposite end of the stem, the wheel capable of rotating relative to the stem; and

a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem; and

a brake system comprising:

a brake rod disposed substantially parallel to a longitudinal axis of the stem, the brake rod slidingly constrained near a first end of the brake rod to allow movement of the rod from an engaged position to a disengaged position;

a handle coupled to the brake rod at the first end of the brake rod;

a pivot arm disposed at a second end of the brake rod and pivotally coupled to the brake rod, the pivot arm rigidly coupled to a brake shaft such that movement of the brake rod toward the engaged position rotates the brake shaft in one direction and movement of the brake rod toward the disengaged position rotates the brake shaft in another direction;

a brake pad coupled to the brake shaft to engage with or disengage from the wheel depending on the rotation of the brake shaft; and

a bracket having a sleeve to receive the brake shaft, the sleeve allowing rotation of the brake shaft within the sleeve, the bracket adjustably mounted to the barrier hauler such that the brake shaft and the brake pad may be selectively adjusted and moved toward the wheel; and

a barrier comprising:

at least one wheel positioned at a first end of the barrier to act in cooperation with the at least one wheel of the barrier hauler when the barrier hauler is engaged with the barrier.

2 . The system of claim 1 , wherein:

a sleeve is positioned at a second end of the barrier opposite the at least one wheel of the barrier; and

an attachment bar is positioned within the sleeve, the attachment bar having an aperture to receive the engagement pin of the lift arm when the barrier hauler is engaged with the barrier.

3 . The system of claim 1 , wherein the engagement pin is curved or angled relative to a longitudinal axis of the lift arm.

4 . The system of claim 1 , wherein the barrier hauler further comprises a storage sleeve capable of receiving the attachment bar in a stored position when the barrier hauler is not engaged to the barrier.

5 . The system of claim 1 , wherein the barrier hauler further comprising:

a brace arm coupled to the stem between the first end and second end, the brace arm extending from the stem in a direction opposite the lift arm; and

a handle coupled to the brace arm.

6 . The system of claim 1 , further comprising a storage arm coupled to the stem between the first end and second end, the storage arm having a slot through which a pin may be inserted to secure the barrier hauler to a barrier in a stored position.

7 . A barrier hauler, comprising:

a stem;

a handle positioned at one end of the stem;

an axle disposed proximate an opposite end of the stem;

at least one wheel rotatably coupled to the axle;

a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem;

a brake system comprising:

a brake rod disposed substantially parallel to a longitudinal axis of the stem, the brake slidingly constrained near a first end of the brake rod to allow movement of the rod from an engaged position to a disengaged position;

a handle coupled to the brake rod at the first end of the brake rod;

a pivot arm disposed at a second end of the brake rod and pivotally coupled to the brake rod, the pivot arm rigidly coupled to a brake shaft such that movement of the brake rod toward the engaged position rotates the brake shaft in one direction and movement of the brake rod toward the disengaged position rotates the brake shaft in another direction;

a brake pad coupled to the brake shaft to engage with or disengage from the wheel depending on the rotation of the brake shaft; and

a bracket having a sleeve to receive the brake shaft, the sleeve allowing rotation of the brake shaft within the sleeve, the bracket adjustably mounted to the barrier hauler such that the brake shaft and the brake pad may be selectively adjusted and moved toward the wheel.

8 . The barrier hauler of claim 7 , further comprising an attachment bar having an aperture to receive the engagement pin of the lift arm when the attachment bar is engaged to a barrier.

9 . The barrier hauler of claim 7 , wherein the engagement pin is curved or angled relative to a longitudinal axis of the lift arm.

10 . The barrier hauler of claim 7 , wherein the barrier hauler further comprises a storage sleeve capable of receiving the attachment bar in a stored position when the barrier hauler is not engaged to a barrier.

11 . The barrier hauler of claim 7 , further comprising:

a brace arm coupled to the stem between the first end and second end, the brace arm extending from the stem in a direction opposite the lift arm; and

a handle coupled to the brace arm.

12 . The barrier hauler of claim 7 , further comprising a storage arm coupled to the stem between the first end and second end, the storage arm having a slot through which a pin may be inserted to secure the barrier hauler to a barrier in a stored position.

13 . A method of deploying a vehicle barrier with the vehicle mitigation system of claim 1 , comprising:

attaching an attachment bar to the barrier, the attachment bar having an aperture;

positioning the engagement pin of the barrier hauler into the aperture of the attachment bar;

rotating the stem of the barrier hauler away from the barrier to lift the barrier; and

rolling the barrier hauler to move the barrier to a selected location.

14 . The method of claim 13 , further comprising engaging the brake system to prevent rolling of the barrier hauler.

15 . The method of claim 14 , further comprising lowering the barrier at the selected location.

16 . The method of claim 15 , wherein lowering the barrier at the selected location further comprises engaging a brace arm to assist in rotating the stem of the barrier hauler toward the barrier to lower the barrier.

17 . A barrier hauler, comprising:

a stem;

a handle positioned at one end of the stem;

an axle disposed proximate an opposite end of the stem;

two wheels rotatably coupled to the axle;

a lift arm having an engagement pin, the lift arm rigidly fixed relative to the stem and disposed at a first angle to the stem;

a brake system comprising:

a brake rod disposed substantially parallel to a longitudinal axis of the stem, the brake slidingly constrained near a first end of the brake rod to allow movement of the rod from an engaged position to a disengaged position;

a handle coupled to the brake rod at the first end of the brake rod;

a pivot arm disposed at a second end of the brake rod and pivotally coupled to the brake rod, the pivot arm rigidly coupled to a brake shaft such that movement of the brake rod toward the engaged position rotates the brake shaft in one direction and movement of the brake rod toward the disengaged position rotates the brake shaft in another direction;

two brake pads coupled to the brake shaft, wherein each of the two brake pads is configured to engage with or disengage from a respective wheel of the two wheels depending on the rotation of the brake shaft; and

a bracket having a sleeve to receive the brake shaft, the sleeve allowing rotation of the brake shaft within the sleeve.

18 . The barrier hauler of claim 17 , further comprising an attachment bar having an aperture to receive the engagement pin of the lift arm when the attachment bar is engaged to a barrier.

19 . The barrier hauler of claim 18 , further comprising a storage sleeve capable of receiving the attachment bar in a stored position when the barrier hauler is not engaged to a barrier.

20 . The barrier hauler of claim 17 , wherein the bracket is adjustably mounted to the barrier hauler such that the brake shaft and the two brake pads may be selectively adjusted and moved toward the two wheels.
