Abstract
A wheelchair comprising a frame, a seat assembly attached to the frame, two rear wheels attached to the frame, and at least one front wheel assembly attached to the frame. The frame defines a front face and two side faces. The front face is defined by one or more structural elements situated along a front of the frame, while the side faces are defined by two top side members and two corresponding bottom side members. The front face and the two side faces result in three non-orthogonal planes, which contribute to the strength and stiffness of the frame.
Claims32
A wheelchair, comprising:
- a frame with a front face and two side faces, said frame comprising:
- one or more structural members situated along a front of said frame, said structural members defining said front face;
- two top side members, wherein one end of each of said top side members extend from said front towards a rear of said frame;
- two corresponding bottom side members, wherein one end of each of said bottom side members extends from said front, at a location below where said top side members extend from said front, towards said rear of said frame;
- wherein each of said two side faces are defined in part by:
- one of said top side members;
- one of said corresponding bottom side members;
- and
- an edge of said front face, extending from where said one of said top side members extend from said front to where said one of said bottom side members extend from said front;
- and
- wherein said front face is not substantially perpendicular to either of said side faces, said side faces are not substantially parallel to one another, and said side faces are not substantially perpendicular to the ground;
- a seat assembly attached to said frame;
- two rear wheels attached to said frame;
- and
- at least one front wheel assembly attached to said frame.

A frame for a wheelchair, said frame comprising:
- one or more structural members situated along a front of said frame, said structural members defining said front face, said front face being not substantially perpendicular to the ground;
- two top side members, wherein one end of each of said top side members extend from said front towards a rear of said frame;
- two corresponding bottom side members, wherein one end of each of said bottom side members extend from said front, at a location below where said top side members extend from said front, towards said rear of said frame;
- wherein each of said two side faces are defined in part by:
- one of said top side members;
- one of said corresponding bottom side members;
- and
- an edge of said front face, extending from where said one of said top side members extend from said front to where said one of said bottom side members extend from said front;
- and
- wherein said front face is not substantially perpendicular to either of said side faces, said side faces are not substantially parallel to one another, and said side faces are not substantially perpendicular to the ground.
