Wedge-shaped vehicle barrier with sling

摘要

A wedge-shaped vehicle barrier, including a top assembly pivotably coupled to a bottom assembly; a mechanism coupled to the top assembly and coupled to the bottom assembly, where the mechanism moves the top assembly between a first position that is substantially horizontal and a second position at a first angle; and one or more flexible slings coupled to a distal portion of the top assembly and a distal portion of the bottom assembly, where the one or more slings prevent the top assembly from rotating beyond a second angle when the top assembly is engaged by a vehicle, the second angle being greater than or equal to the first angle.

1. A wedge-shaped vehicle barrier, comprising:
a top assembly pivotably coupled to a bottom assembly; a mechanism coupled to the top assembly and coupled to the bottom assembly, where the mechanism moves the top assembly between a first position that is substantially horizontal and a second position at a first angle, the mechanism for repeatedly cycling the top assembly between the first position and the second position; and one or more flexible slings coupled to a distal portion of the top assembly and a distal portion of the bottom assembly, where the one or more slings prevent the top assembly from rotating beyond a second angle when the top assembly is engaged by a vehicle, the second angle being greater than or equal to the first angle, wherein each sling comprises synthetic fiber that is wound into a continuous loop, wherein a portion of the loop is encased in one or more layers of a wear resistant material to couple the sling to itself at a first point near a first end to form a first loop end, at a second point near a second end to form a second loop end, and at a third point between the first and second points, and wherein the first loop end is coupled to the top assembly and the second loop end is coupled to the bottom assembly.
