Abstract

Various powered mobility systems for users are described. The powered mobility system can include at least one powered skate. The powered skate can include a platform, a plurality of wheels, and a motor assembly. The motor assembly can include a motor. The motor can be powered by a power supply. A motor control can be implemented to determine when power is supplied to the motor from the power supply.

Claims (36)

1. A powered mobility system, comprising:

a powered skate comprising:

a frame comprising a platform configured to receive a user's foot and secure the user's foot within the platform;

a plurality of wheels comprising a driving wheel disposed rearwardly from a heel end of the powered skate and a side wheel;

a motor assembly comprising a motor and a drive shaft;

a transmission assembly comprising a gear transmission, the gear transmission comprising at least a driving gear connected to the drive shaft and a driven gear configured to spin the driving wheel;

a connector that couples the motor assembly to the frame, the connector being configured to flex when the powered skate rolls over non-flat riding surfaces, wherein the connector is biased in a direction towards a riding surface;

a power supply configured to power the motor assembly and to cause the motor to spin the driving wheel; and

a non-powered skate.

2. The powered mobility system of claim 1 , wherein the powered skate further comprises a heel end, the heel end comprising a pressure sensor configured to detect a pressure applied to the heel end by the user.

3. The powered mobility system of claim 1 , wherein the powered skate further comprises a controller configured to detect shifts in the user's position and adjust a speed of the motor.

4. The powered mobility system of claim 1 , wherein the platform comprises at least one strap for securing the user's foot within the platform.

5. The powered mobility system of claim 1 , wherein the non-powered skate comprises a plurality of wheels disposed near a toe end and a heel end of the platform.

6. The powered mobility system of claim 1 , wherein the driving wheel is supported at one end of the connector and wherein the motor assembly is disposed rearwardly from the platform and above the driving wheel such that when the user leans on the end of a swing arm assembly, the motor drives the driving wheel.

7. The powered mobility system of claim 6 , wherein a speed of the motor increases when the motor assembly pivots in an upward direction.

8. The powered mobility system of claim 6 , wherein a speed of the motor increases when the motor assembly pivots towards the platform and the platform pivots towards the motor assembly.

9. The powered mobility system of claim 8 , wherein the driving wheel is configured to contact the riding surface when the motor assembly pivots towards the platform and the platform pivots towards the motor assembly.

10. The powered mobility system of claim 6 , wherein the driving wheel and motor assembly are disposed at one end of the connector and wherein the power supply is disposed rearwardly from the platform and above the motor assembly such that when the user leans on the end of the swing arm assembly, the power supply supplies power to the motor to drive the driving wheel.

11. The powered mobility system of claim 1 , wherein a portion of the side wheel extends above the platform when the side wheel is in contact with the riding surface.

12. The powered mobility system of claim 1 , wherein the entire side wheel is disposed to a lateral side of the platform.

13. A powered skate, comprising:

a frame comprising a platform configured to receive a portion of a user's foot and secure the portion of the user's foot within the platform such that the user's toes protrude forward of the platform;

a plurality of wheels comprising a driving wheel disposed rearwardly from a heel end of the powered skate and a side wheel;

a motor assembly comprising a motor and a drive shaft;

a transmission assembly comprising a gear transmission, the gear transmission comprising at least a driving gear connected to the drive shaft and a driven gear configured to spin the driving wheel;

a connector that couples the motor assembly to the frame, the connector being configured to flex when the powered skate rolls over non-flat riding surfaces, wherein the connector is biased in a direction towards a riding surface; and

a power supply configured to power the motor assembly and to cause the motor to spin the driving wheel.

14. The powered skate of claim 13 , wherein the powered skate further comprises a heel end, the heel end comprising a pressure sensor configured to detect a pressure applied to the heel end by the user.

15. The powered skate of claim 13 , wherein the powered skate further comprises a controller configured to detect shifts in the user's position and adjust a speed of the motor.

16. The powered skate of claim 13 , wherein the driving wheel is supported at one end of the connector and wherein the motor assembly is disposed rearwardly from the platform and above the driving wheel such that when the user leans on the end of a swing arm assembly, the motor drives the driving wheel.

17. The powered skate of claim 16 , wherein a speed of the motor increases when the motor assembly pivots in an upward direction.

18. The powered skate of claim 16 , wherein a speed of the motor increases when the motor assembly pivots towards the platform and the platform pivots towards the motor assembly.

19. The powered skate of claim 18 , wherein the driving wheel is configured to contact the riding surface when the motor assembly pivots towards the platform and the platform pivots towards the motor assembly.

20. The powered skate of claim 16 , wherein the driving wheel and motor assembly are disposed at one end of the connector and wherein the power supply is disposed rearwardly from the platform and above the motor assembly such that when the user leans on the end of the swing arm assembly, the power supply supplies power to the motor to drive the driving wheel.

21. The powered skate of claim 13 , wherein a portion of the side wheel extends above the platform when the side wheel is in contact with the riding surface.

22. The powered skate of claim 13 , wherein the entire side wheel is disposed to a lateral side of the platform.
