Adjustable air-deflecting panel for a vehicle

1. An adjustable air-deflecting panel for mounting to a vehicle comprising:

at least one panel;

a plurality of mounts adapted for mounting the panel to the vehicle, each mount comprising a first vehicle mount portion for mounting to the vehicle and a second panel mount portion for mounting the panel to the first vehicle mount portion, the first vehicle mount portion being pivoted to the second panel mount portion so as to pivot about an axis to thereby pivotally couple the panel to the vehicle for pivoting about the pivot axis, the first vehicle mount portion comprising a first engagement surface and the second panel mount portion comprising a second engagement surface, the first and second engagement surfaces sliding adjacent to one another as the panel is pivoted from one position to another position, the first and second engagement surfaces comprising respective inter-engaging features operable to engage one another upon clamping the first and second engagement surfaces together to thereby prevent pivoting of the panel about the pivot axis relative to the vehicle.

2. An adjustable air-deflecting panel according to claim 1 wherein the inter-engaging features comprise plural detents.

3. An adjustable air-deflecting panel according to claim 1 wherein the inter-engaging features comprise a plurality of projections and grooves oriented parallel to the direction of the pivot axis.

4. An adjustable air-deflecting panel according to claim 1 wherein the first engagement surface comprises an arcuate convex surface portion of a first radius perpendicular to the pivot axis and extending from the pivot axis, the second engagement surface comprises an arcuate concave surface portion of a second radius perpendicular to the pivot axis and extending from the pivot axis, the second radius being greater than the first radius and dimensioned such that the first and second engagement surfaces are slidably coupled together prior to being clamped together.

5. An adjustable air-deflecting panel according to claim 4 wherein the first vehicle mount portion comprises upper and lower wall surfaces with the first engagement surface being positioned between the upper and lower wall surfaces, and wherein the second panel mount portion comprises a channel portion with upper and lower flange portions defining respective first and second channel walls and a base portion extending between the first and second channel walls, and the second engagement surface comprising a portion of the base portion and being positioned at the interior of the channel portion between the first and second channel walls.

6. An adjustable air-deflecting panel according to claim 5 wherein the base portion comprises a fastener receiving slot elongated in the direction of sliding of the first engagement surface relative to the second engagement surface and a fastener passing through the slot and being threaded into the first surface portion, whereby the fastener is operable when pivoted in a first direction to clamp the first and second engagement surfaces together and when pivoted in a second direction opposite to the first direction to release the first and second engagement surfaces from clamped engagement so as to permit relative sliding of the first and second surfaces.

7. An adjustable air-deflecting panel according to claim 1 wherein the air-deflecting panel comprises a side extender panel and wherein the inter-engaging features comprise first and second sets of spaced apart inter-engaging features, the first set of inter-engaging features being positioned such that when clamped together the side extender panel is locked at an obtuse angle relative to a rear wall surface of the vehicle, and the second set of inter-engaging features being positioned such that when clamped together the side extender panel is locked at an acute angle relative to a rear wall surface of the vehicle.

8. An adjustable air-deflecting panel according to claim 4 wherein the air-deflecting panel comprises a side extender panel and wherein the inter-engaging features comprise first and second sets of spaced apart inter-engaging features, the first set of inter-engaging features being positioned such that when clamped together the panel is locked at an obtuse angle relative to a rear wall surface of the vehicle, and the second set of inter-engaging features being positioned such that when clamped together the panel is locked at an acute angle relative to a rear wall surface of the vehicle.

9. An adjustable air-deflecting panel according to claim 1 comprising position indicators on at least one of the first vehicle mount portion and second panel mount portion to indicate the pivot position of the panel.

10. An adjustable air-deflecting panel according to claim 1 wherein the second panel mount portion comprises a grab handle mounting projection extending away from the panel.

11. An adjustable air-deflecting panel for mounting to a vehicle comprising:

at least one panel;

a plurality of mounts adapted for mounting the panel to the vehicle, each mount comprising a first vehicle mount portion adapted for mounting to the vehicle and a second panel mount portion adapted for mounting to the panel, the first vehicle mount portion being pivoted to the second panel mount portion so as to pivot about an axis to thereby pivotally couple the panel to the vehicle for pivoting about the pivot axis, the first vehicle mount portion and the second panel mount portion comprising means for engaging one another to prevent pivoting of the panel about the pivot axis relative to the vehicle.
