Abstract

A motorized lute includes a first plate having a first plurality of teeth and a second plate having a second plurality of teeth. The second plate is slidably coupled to the first plate. A motor assembly is configured to engage the second plate provide a lateral force to the second plate and cause horizontal oscillation of said second plate. Wheels are disposed on each side of the first and second plate. A lute pole is coupled to the first plate and includes a primary handle and actuator for controlling speed and power of the motor.

Claims (33)

1. A motorized lute for leveling a ground surface, the motorized lute comprising:

a first plate having a first plurality of teeth,

the first plate further comprising a first plate aperture and a plurality of slots disposed on each side of the first plate aperture, the first plate configured to orientate orthogonally to the ground surface during operation of the motorized lute;

a first wheel bracket and a second wheel bracket each coupled to the first plate;

a plurality of wheels coupled to the first wheel bracket and the second wheel bracket;

a second plate slidably coupled to the first plate, the second plate configured to orientate orthogonally to the ground surface during operation of the motorized lute, the second plate having a second plurality of teeth and an oblong opening overlapping the first plate aperture;

one or more ball bearings engaged with the plurality of slots of the first plate;

a motor housing coupled to the first plate and disposed between the first wheel bracket and the second wheel bracket;

a motor assembly disposed within the motor housing, the motor assembly comprising a driver gear, and an output shaft coupled to the driver gear, wherein the output shaft extends through the first plate aperture and engages with at least a portion of the oblong opening, thereby causing horizontal oscillation of the second plate; and

a lute pole extending from the motor housing, the lute pole including a primary handle and an actuator for controlling the motor assembly.

2. The motorized lute of claim 1 , wherein the first plate is disposed between the motor housing and the second plate.

3. The motorized lute of claim 1 , wherein the first plate is stationary with the motor housing.

4. The motorized lute of claim 1 , wherein the first wheel bracket and the second wheel bracket are each fixedly coupled to the first plate.

5. The motorized lute of claim 1 , wherein the first plate and the lute pole form an angle such that the first plate is configured align orthogonally to the ground surface during operation.

6. The motorized lute of claim 1 , wherein the oblong opening is in parallel alignment with the first plate aperture.

7. The motorized lute of claim 1 , wherein the oblong opening is on a same plane as the second plurality of teeth.

8. The motorized lute of claim 1 , the plurality of wheels further comprising a bottommost point configured to contact the ground surface during operation, wherein the first plurality of teeth and the second plurality of teeth are configured to extend vertically below the bottommost point.

9. The motorized lute of claim 1 , the plurality of slots further comprising a plurality of elongated slots wherein the one or more ball bearings are configured to slide along each of the plurality of elongated slots.

10. The motorized lute of claim 1 , wherein an end of the lute pole is disposed at a center of the first plate.

11. A motorized lute for leveling a ground surface, the motorized lute comprising:

a first plate having a first plurality of teeth, the first plate being configured to orientate orthogonally to the ground surface during operation of the motorized lute;

a second plate slidably coupled to the first plate, the second plate having a second plurality of teeth, the second plate being configured to orientate orthogonally to the ground surface during operation of the motorized lute;

a motor assembly configured to engage with the second plate and cause horizontal oscillation of the second plate; the first plate further comprising a first plate aperture, the motor assembly further comprising a driver gear and an output shaft coupled to the driver gear, the output shaft configured to extend through the first plate aperture;

a plurality of wheels coupled to the first plate; and

a lute pole coupled to the first plate.

12. The motorized lute of claim 11 , the second plate further comprising an oblong opening wherein the oblong opening is in parallel alignment with the first plate aperture.

13. The motorized lute of claim 12 , wherein the output shaft engages with at least a portion of the oblong opening.

14. The motorized lute of claim 12 , wherein the oblong opening is on a same plane as the second plurality of teeth.

15. The motorized lute of claim 11 , wherein the first plate is disposed between the motor assembly and the second plate.

16. The motorized lute of claim 11 , wherein the first plate and the lute pole form an angle such that the first plate is configured align orthogonally to the ground surface during operation.

17. The motorized lute of claim 11 , the plurality of wheels further comprising a bottommost point configured to contact the ground surface during operation, wherein the first plurality of teeth and the second plurality of teeth are configured to extend vertically below the bottommost point.

18. The motorized lute of claim 11 , further comprising a plurality of elongated slots wherein one or more ball bearings are configured to slide along each of the plurality of elongated slots.

19. The motorized lute of claim 11 , wherein an end of the lute pole is disposed at a center of the first plate.
