Abstract
A steering system for a wheelchair includes a steering device configured to be engaged by a user, a front wheel operably connected to the steering device, and a frame assembly configured to carry the steering device and the front wheel. The frame assembly is configured to removably engage a mounting member of the wheelchair. A mounting assembly can be coupled to the frame assembly. The mounting assembly is configured to selectively couple to the mounting member of the wheelchair and selectively electrically connect to a motorized drive assembly coupled to the wheelchair.
Claims37
A steering system for a wheelchair comprising:
- a steering device configured to be engaged by a user;
- a front wheel operably connected to the steering device;
- and
- a frame assembly configured to carry the steering device and the front wheel,
- wherein the frame assembly is configured to removably engage a connection assembly fastened to an axle of the wheelchair,
- wherein a motorized drive assembly is configured to removably engage the wheelchair, the motorized drive assembly being positioned rearward of the axle of the wheelchair, the axle defines an axis of rotation of a pair of rear wheels of the wheelchair, and
- wherein the connection assembly is configured to electrically connect the motorized drive assembly to the steering device.
A method of selectively connecting a steering assembly to a wheelchair comprising:
- lifting a first end of a frame assembly, the first end of the frame assembly carrying a mounting assembly, a second end of the frame assembly, opposite the first end, carrying a steering member and a front wheel operably connected to the steering member;
- maintaining contact of the front wheel with a surface;
- and
- engaging the mounting assembly with a connection assembly coupled to the wheelchair while a motorized drive assembly is coupled to the wheelchair, the motorized drive assembly positioned rearward of an axis of rotation of a pair of rear wheels of the wheelchair, the connection assembly is electrically connected to the motorized drive assembly, the engaging step includes fastening the mounting assembly to the connection assembly, and connecting a first electrical connector of the mounting assembly with a second electrical connector of the connection assembly electrically connecting the steering assembly to the motorized drive assembly.
A steering assembly for a wheelchair comprising:
- a steering member;
- a front wheel operably connected to the steering member;
- a frame assembly configured to carry the steering member and the front wheel at a first end of the frame assembly;
- and
- a mounting assembly coupled to a second end of the frame assembly, opposite the first end, the mounting assembly configured to selectively couple to a rear axle of the wheelchair and selectively electrically connect to a motorized drive assembly removably coupled to the rear axle of the wheelchair
- wherein the mounting assembly is configured to electrically connect and selectively couple to a connection assembly fastened to a rear axle of the wheelchair, the connection assembly being electrically connected to the motorized drive assembly, and
- wherein in response to the mounting assembly electrically connecting to the connection assembly, the steering member is in electronic communication with the motorized drive assembly.
A removable steering system for a wheelchair comprising:
- a frame assembly defining a first end opposite a second end;
- a wheelchair mounting assembly coupled to the first end of the frame assembly;
- a steering assembly including a steering member operably connected to a front wheel, the steering assembly coupled to the second end of the frame assembly;
- and
- an actuation member coupled to the steering assembly, the actuation member operably connected to the wheelchair mounting assembly,
- wherein, while the front wheel remains in contact with a surface, the frame assembly is configured to be moved between a first position, where the wheelchair mounting assembly engages a portion of the wheelchair to attach the steering system to the wheelchair, and a second position, where the wheelchair mounting assembly disengages the portion of the wheelchair to detach the steering system from the wheelchair,
- wherein a motorized drive assembly is removably mounted to the wheelchair while the frame assembly is moved between the first and second positions, and
- wherein actuation of the actuation member disengages the frame assembly from the portion of the wheelchair.
