Patent ID: 7314020

Claim:
An over-height vehicle barrier, said barrier having a series of over-height vehicle engaging members mounted on a supporting beam mounted above a roadway such that each member hangs beneath the supporting beam for possible engagement by an over-height vehicle, each member being pivotally mounted to the supporting beam at an upper end portion thereof such that each member can pivot about the axis of the beam independently of the other members when struck by an over-height vehicle, and a second beam spaced from the supporting beam to be engaged by said members pivoting about the supporting beam when struck by an over-height vehicle and to thereby cause the members to pivot in a return direction, wherein engagement of said members by a vehicle generates a warning noise to alert the driver of the vehicle, and wherein each of the members is in the form of a blade having opposed sides and a relatively narrow leading face towards the oncoming traffic, the members being mounted with the adjacent sides of adjacent members being in closely spaced relationship whereby the series of vehicle engaging members provides the appearance of a solid beam facing the oncoming traffic.
