Abstract
A multifunction mobility device includes a frame that includes a seat member, a first wheeled leg ember coupled to a first side of the seat member and a second wheeled leg member coupled to a second side of the seat member. The first wheeled leg member and the second wheeled leg member each includes an upper leg portion pivotally coupled to the seat member at a distal end and defining an upper arm recess, and a lower leg portion pivotally coupled to the upper leg portion, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode where the upper leg portion is pivoted relative to the lower leg portion such that the lower leg portion nests into the upper arm recess.
Claims20
A multifunction mobility device, comprising:
- a frame that is configurable between a plurality of modes, the frame comprising:
- a seat member;
- a first wheeled leg member coupled to a first side of the seat member;
- and
- a second wheeled leg member coupled to a second side of the seat member, the first wheeled leg member and the second wheeled leg member each comprising:
- an upper leg portion extending between a distal end and a proximal end, the upper leg portion pivotally coupled to the seat member at the distal end and comprising a curved wall that defines an upper arm recess;
- a lower leg portion extending between a first end and a second end, the lower leg portion pivotally coupled to the upper leg portion at the first end, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode where the upper leg portion is pivoted relative to the lower leg portion such that the lower leg portion nests into the upper arm recess and such that an end surface of the first end of the lower leg portion nests within the proximal end of the upper leg portion.
A multifunction mobility device, comprising:
- a frame that is configurable between a plurality of modes, the frame comprising:
- a seat member;
- a first wheeled leg member coupled to a first side of the seat member;
- and
- a second wheeled leg member coupled to a second side of the seat member, the first wheeled leg member and the second wheeled leg member each comprising:
- an upper leg portion extending between a distal end and a proximal end, the upper leg portion pivotally coupled to the seat member at the distal end and comprising a curved wall that defines an upper arm recess;
- and
- a lower leg portion extending between a first end and a second end, the lower leg portion pivotally coupled to the upper leg portion at the first end, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode, wherein the upper leg portion is pivoted with respect to the lower leg portion such that the lower leg portion nests into the upper arm recess and such that an end surface of the first end of the lower leg portion nests within the proximal end of the upper leg portion;
- one or more actuators that transition the frame between the plurality of modes;
- and
- a control unit communicatively coupled to the one or more actuators, wherein the control unit is configured to operate the one or more actuators to transition the frame between the plurality of modes including the collapsed transport and storage mode.
A multifunction mobility device, comprising:
- a frame that is configurable between a plurality of modes including at least a power wheelchair mode, a power walker mode, and a power scooter mode, the frame comprising:
- a seat member;
- a first wheeled leg member coupled to a first side of the seat member;
- and
- a second wheeled leg member coupled to a second side of the seat member, the first wheeled leg member and the second wheeled leg member each comprising:
- an upper leg portion extending between a distal end and a proximal end, the upper leg portion pivotally coupled to the seat member at the distal end and comprising a curved wall that defines an upper arm recess;
- a lower leg portion extending between a first end and a second end, the lower leg portion pivotally coupled to the upper leg portion at the first end, the upper leg portion and the lower leg portion being collapsible into a collapsed transport and storage mode, wherein the upper leg portion is pivoted relative to the lower leg portion to nest the lower leg portion into the upper arm recess and such that an end surface of the first end of the lower leg portion nests within the proximal end of the upper leg portion;
- one or more actuators coupled to the frame;
- and
- a control unit communicatively coupled to the one or more actuators, wherein the control unit is configured to operate the one or more actuators to transition the frame into each mode.
