Abstract
An adult scale three-wheeled device facilitates movement for mobility challenged persons. The device is foot propelled while seated either through walking while seated or pedaling. The device is provided with a limited footprint for navigating confined areas while the individual is seated in a substantially standing position, with the pedals being repositionable so as to allow unobstructed walking while remaining seated. A lockable braking system prevents one or more wheels from turning. The device is collapsible for storage.

An orthopedic mobility device comprising:
- a front frame element having at least one front wheel rotatably mounted thereto;
- said front wheel communicably coupled by an elongated member to a steering element;
- said front frame element including a head tube connected to a rear frame element by a seat supporting element;
- said rear frame element having at least a left and a right rear wheel rotatably mounted thereto;
- said seat supporting element including a left seat support and a right seat support, the left and right seat supports extending in a splayed orientation from the head tube towards the rear frame element and terminating, respectively, at left and right hinges;
- a cross-bar extending between the left and right seat supports at a location between the head tube and the right hinges;
- the rear frame element including a left wheel supporting hinged coupled to the left hinge, and a right wheel support hinged coupled to the right hinge, wherein said at least left and right rear wheels are configured to rotate relative to the front frame element and fold into a final position closer to the front frame element than in an unfolded position;
- said seat supporting element supporting a seat that maintains an adult in a near standing position;
- and
- the front and rear wheels being positioned so as to create a limited footprint allowing maneuverability of said device indoors;
- and
- said limited footprint being defined by an aspect ratio of a seat height to a greatest distance between geometric centers of any two wheels, said aspect ratio being at least 1.1:1.
