Abstract
An air deflector blade for vehicles and the like is pivotally movable between a substantially vertical orientation and a substantially horizontal orientation in response to the wind velocity created thereupon. The pivotal mounting enables the blade to rotate between the vertical and horizontal positions.
Claims29
A velocity responsive deflector blade assembly, comprising:
- (a) a deflector blade,
- (b) a mounting assembly for each end of the blade, each assembly comprising:
- (1) a blade cap, the end of the deflector blade being journalled thereonto,
- (2) a casting having means defining a ledge, the blade cap normally seating on the ledge,
- (3) means pivotally mounting the blade cap to the casting, and
- wherein the blade cap pivotally rotates about the pivotal mounting means relative to the casting in response to the velocity of air impinging against the deflector blade, the deflector blade directing a stream of air over a portion of a vehicle when a vehicle is moving at low speeds and pivotally rotating to a position parallel to the stream of air impinging thereagainst when a vehicle is moving at high speeds to minimize the drag created by the deflector blade.

A velocity responsive deflector blade assembly for mounting onto a horizontal surface of a vehicle, comprising:
- (a) a deflector blade,
- (b) means for pivotally and rotatably mounting the deflector blade to the vehicle surface,
- (c) means for normally urging the blade to a position normal to the horizontal surface, and
- wherein the blade pivotally rotates between the normal position and a position parallel to the horizontal surface in response to the velocity of air impinging against the deflector blade, the deflector blade directing a stream of air over a portion of the vehicle when the vehicle is moving at low speeds and rotating to a position parallel to the horizontal surface when the vehicle is moving at high speeds to minimize the drag created by the deflector blade.
