Abstract

The invention relates to a kit providing a wheelchair adaptable in one of a hand powered mode and a motorized mode. The kit comprises: a wheelchair frame with two wheels rotatably mounted; a propulsion unit frame having at least one motor mounted thereto, a right and a left power driven wheels operably and distinctly coupled to the at least one motor, the right and left power driven wheels being characterized by a respective first and second rotation speeds, the at least one motor being coupled with at least one battery and a controller for controlling the first and second rotation speeds; and a mounting structure having at least one first mounting element carried by the propulsion unit frame and at least one second mounting element carried by the wheelchair, the at least one first and second mounting elements being adapted to securably and releasably mate into one another form mounting the propulsion unit to the wheelchair frame, the power driven wheels being located between the wheelchair wheels when the propulsion unit is mounted to the wheelchair.

Claims (23)

1. A propulsion unit adapted to be removably mounted to a wheelchair having a frame and wheels rotatably mounted thereto, the propulsion unit comprising:
a propulsion unit frame adapted to be removably secured to the wheelchair, said propulsion unit frame having at least a first and a second power driven wheels rotatably mounted to the propulsion unit frame, said power driven wheels being mounted between the wheelchair wheels;
at least one motor operatively connected to said at least two power driven wheels to distinctly provide energy thereto, said first and second power driven wheels having a respective first and second rotation speeds;
at least one portable energy source coupled to the at least one motor;
and at least one controller operatively connected to the at least one motor for controlling the first and second rotation speeds of said first and second power driven wheels.
2. A propulsion unit as claimed in claim 1, comprising two motors, each of said motor being operatively coupled with one of said power driven wheels.
3. A propulsion unit as claimed in one of claims 1 and 2, comprising a first part of a securing mechanism for removably securing said propulsion unit frame to said wheelchair, said first part being adapted for securely engaging a second part of said securing mechanism mounted to said wheelchair when said propulsion unit is mounted to said wheelchair.
4. A propulsion unit as claimed in claim 3, wherein at least one of said first and second part of said securing mechanism is adjustable in at least one of height and width depending on said height and width of said wheelchair to ensure a meshing engagement of said first and second part of said securing mechanism when mounting said propulsion unit to said wheelchair.
5. A propulsion unit as claimed in one of claims 3 and 4, comprising a control lever operatively coupled with said securing mechanism for unsecuring said propulsion unit from said wheelchair.
6. A propulsion unit as claimed in any one of claims 1 to 5, comprising a joystick device operatively connected to said controller, said joystick device being adapted to control the first and second rotation speeds of said power driven wheels.
7. A propulsion unit as claimed in any one of claims 1 to 6, comprising at least one stabilizing member mounted to said propulsion unit frame stabilizing said propulsion unit when unsecured to said wheelchair.
8. A propulsion unit as claimed in any one of claims 1 to 8, comprising a suspension allowing said power driven wheels to keep contact with the ground when said propulsion unit is mounted to said wheelchair.
9. A propulsion unit as claimed in any one of claims 1 to 9, wherein said wheelchair comprises a seat and said propulsion unit is inserted under said seat when mounted to said wheelchair.
10. A kit for motorizing a wheelchair having a frame and wheels mounted thereto, comprising:
a power drive assembly having a frame with two power driven wheels adapted to be rotatably mounted thereto, each of said power driven wheels adapted to be operatively connected to at least one motor, said motors adapted to be coupled to at least one energy source and to at least one controller controlling the rotation of said power driven wheels; and a securing assembly for fastening said power drive assembly to said wheelchair, said securing assembly having at least a male member and a female member, said at least one male and female members adapted to be mounted to a respective one of said wheelchair frame and said power drive assembly frame and being adapted to removably mate with one another when the power drive assembly mounted to said wheelchair, said power driven wheels being located between said wheelchair wheels when said propulsion unit is mounted to said wheelchair.
11. A kit as claimed in claim 10, wherein at least one of said male and female member of said securing assembly is adjustable in at least one of height and width depending on said height and width of said wheelchair to ensure a meshing engagement of said male and female of said securing assembly when mounting said propulsion unit to said wheelchair.
12. A kit as claimed in one of claims 10 and 11, comprising a control lever operatively coupled with said securing assembly for unsecuring said power drive assembly from said wheelchair.
13. A kit as claimed in any one of claims 10 to 12, comprising a joystick device operatively connected to said controller, said joystick device being adapted to control the rotation speed of said power driven wheels.
14. A kit as claimed in any one of claims 10 to 13, wherein said power drive assembly comprises at least one stabilizing member mounted to said power drive assembly frame stabilizing said power drive assembly when unsecured to said wheelchair.
15. A kit as claimed in any one of claims 10 to 14, wherein said power drive assembly comprises a suspension allowing said power driven wheels to keep contact with the ground when said power drive assembly is mounted to said wheelchair.
16. A kit providing a wheelchair adaptable in one of a hand powered mode and a motorized mode, comprising a wheelchair frame with two wheels rotatably mounted thereto;
a propulsion unit frame having at least one motor mounted thereto, a right and a left power driven wheels operably and distinctly coupled to the at least one motor, said right and left power driven wheels being characterized by a respective first and second rotation speeds, said at least one motor being coupled with at least one battery and a controller for controlling said first and second rotation speeds; and a mounting structure having at least one first mounting element carried by said propulsion unit frame and at least one second mounting element carried by said wheelchair, said at least one first and second mounting elements being adapted to securably and releasably mate into one another form mounting said propulsion unit to said wheelchair frame, said power driven wheels being located between said wheelchair wheels when said propulsion unit is mounted to said wheelchair.
17. A combination as claimed in claim 16, said propulsion unit comprises two motors, each of said motor being operatively coupled with one of said power driven wheels.
18. A combination as claimed in one of claims 16 and 17, wherein at least one of said at least one first and second mounting element of said mounting structure is adjustable in at least one of height and in width depending on said height and width of said wheelchair to ensure a meshing engagement of said at least one first and second mounting element of said mounting structure when mounting said propulsion unit to said wheelchair.
19. A combination as claimed in any one of claims 16 to 18, comprising a control lever operatively coupled with said mounting structure for unsecuring said propulsion unit from said wheelchair.
20.A combination as claimed in any one of claims 16 to 19, comprising a joystick device operatively connected to said controller, said joystick device being adapted to control the first and second rotation speeds of said power driven wheels.
