Abstract

Various embodiments of an apparatus for changing the in-air pitch and/or roll of a land craft are described herein. The apparatus may include a steering input mechanism, a support structure, and an articulator. The apparatus may include one or more of a pitch-forward input mechanism, a pitch-back input mechanism, a roll-right input mechanism, and a roll-left input mechanism. The vehicle may include a set of wheels on which the vehicle travels over ground. The steering input mechanism may receive steering inputs from a driver of the vehicle. The steering input mechanism may receive pitch and roll control inputs from the driver. The support structure may connect the steering input mechanism to the vehicle, at least one of the wheels, or the vehicle and the at least one of the wheels. The articulator may rotatably connect the steering input mechanism to the support structure.

First claim

We claim:

1. An apparatus that changes in-air pitch and roll angles of a ground vehicle, comprising:
a steering input mechanism that receives steering inputs and pitch and roll control inputs from a driver of the vehicle;
a support structure that connects the steering input mechanism to the vehicle, at least one wheel of a set of wheels on which the vehicle travels over ground, or the vehicle and the at least one wheel;
an articulator that rotatably connects the steering input mechanism to the support structure and enables rotation of the steering input mechanism about at least two axes parallel to the steering input mechanism;
a pitch-forward and a pitch-back input mechanism, each disposed adjacent to the steering input mechanism on opposite sides of the steering input mechanism from each other, wherein rotation of the steering input mechanism about a first axis of the axes activates the pitch-forward or pitch-back input mechanism; and
a roll-right and a roll-left input mechanism, each disposed adjacent to the steering input mechanism along a side of the steering input mechanism between the pitch-forward and pitch back mechanisms, and each disposed on opposite sides of the steering input mechanism from each other, wherein rotation of the steering input mechanism about a second axis of the axes activates the roll-right or roll-left input mechanism,
wherein activation of at least one of said mechanisms adjusts a rotational speed of one or more of the wheels.

2. The apparatus of claim 1 , wherein the steering input mechanism comprises a panel connecting the steering input mechanism to the articulator, and wherein one or more of said mechanisms comprises a button disposed on the support structure between the steering input mechanism panel and the support structure.

3. The apparatus of claim 2 , wherein the button is electrically connected to an electronic control unit, the electronic control unit storing instructions to adjust the rotational speed.

4. The apparatus of claim 1 , wherein the pitch-forward input mechanism is disposed above a position where the articulator connects to the support structure and the pitch-back input mechanism is disposed below said position, or wherein the pitch-forward input mechanism is disposed below said position and the pitch-back input mechanism is disposed above said position.

5. The apparatus of claim 1 , wherein the roll-right input mechanism is disposed to the right of a position where the articulator connects to the support structure and the roll-left input mechanism is disposed to the left of said position.

6. The apparatus of claim 1 , wherein activation of the pitch-forward mechanism slows the rotational speed of all the wheels of the set of wheels, of a forward subset of the set of wheels, or of a rear subset of the set of wheels, and wherein activation of the pitch-back mechanism increases the rotational speed of all the wheels of the set of wheels, of the forward subset, or of the rear subset.

7. The apparatus of claim 1 , wherein activation of the roll-right mechanism slows the rotational speed of a right subset of the set of wheels, increases the rotational speed of a left subset of the set of wheels, or both, and wherein activation of the roll-left mechanism increases the rotational speed of a right subset, slows the rotational speed of a left subset, or both.

8. An apparatus that changes one or more of in-air pitch and roll angles of a ground vehicle, comprising:
a steering input mechanism that receives steering inputs and one or more of pitch and roll control inputs from a driver of the vehicle;
a support structure that connects the steering input mechanism to at least one of: the vehicle, and one or more wheels of a set of wheels on which the vehicle travels over ground;
an articulator that rotatably connects the steering input mechanism to the support structure and enables rotation of the steering input mechanism about one or more axes parallel to the steering input mechanism;
and one or more of a pitch-forward, a pitch-back, a roll-right, and a roll-left input mechanism disposed adjacent to the steering input mechanism, wherein rotation of the steering input mechanism about at least one of the axes activates one or more of said mechanisms, causing transmission of one or more electrical signals that adjust the rotational speed of one or more wheels of the set of wheels.

9. The apparatus of claim 8 , wherein the articulator comprises a compressible panel, and wherein one or more of said mechanisms comprises a button disposed within the articulator, wherein the button is electrically connected to an electronic control unit, the electronic control unit storing instructions to adjust the rotational speed.

10. The apparatus of claim 9 , further comprising a retractable solenoid, wherein the support structure comprises a steering column, and wherein the solenoid extends from the steering column, through the articulator, and into the steering input mechanism, thereby preventing rotation of the steering input mechanism about the at least one of the axes.

11. The apparatus of claim 8 , wherein the roll-right input mechanism is disposed to the right of a position where the articulator connects to the support structure and the roll-left input mechanism is disposed to the left of said position.

12. The apparatus of claim 8 , wherein the roll-right input mechanism is disposed to the right of a position where the articulator connects to the support structure and the roll-left input mechanism is disposed to the left of said position.

13. The apparatus of claim 8 , wherein activation of the pitch-forward mechanism slows the rotational speed of all the wheels of the set of wheels, of a forward subset of the set of wheels, or of a rear subset of the set of wheels, and wherein activation of the pitch-back mechanism increases the rotational speed of all the wheels of the set of wheels, of the forward subset, or of the rear subset.

14. The apparatus of claim 8 , wherein activation of the roll-right mechanism slows the rotational speed of a right subset of the set of wheels, increases the rotational speed of a left subset of the set of wheels, or both, and wherein activation of the roll-left mechanism increases the rotational speed of a right subset, slows the rotational speed of a left subset, or both.

15. A ground vehicle, comprising:
one or more wheels on which the vehicle travels over ground;
a steering mechanism that adjusts a tilt of at least one of the wheels relative to the vehicle;
a throttle control that increases a rotational speed of at least one of the wheels;
a brake control that decreases the rotational speed of the at least one of the wheels, one or more others of the wheels, or combinations thereof; and
one or more of a pitch-forward, a pitch-back, a roll-right, and a roll-left mechanism, wherein user activation of any of the pitch-forward, pitch-back, roll-right and roll-left mechanisms adjusts one or more of said rotational speeds according to a desired in-air pitch, roll or pitch and roll of the vehicle.

16. The ground vehicle of claim 15 , further comprising an electronic control unit that stores at least one of the desired in-air pitch and roll of the vehicle.

17. The ground vehicle of claim 16 , further comprising one or more yaw rate sensors and a visual display, each electronically connected to the electronic control unit, wherein the yaw rate sensors measure a current pitch, roll, or pitch and roll of the vehicle, and wherein the visual display displays to a user of the vehicle a difference between the desired in-air pitch
