Abstract
A wheeled walking device is disclosed with a carriage frame having a first and second side bar. Each of the side bars includes a proximal and distal end with a transverse bar connecting the side bars in a torsionally rigid manner. A plurality of ground engaging wheels stably support the carriage frame. A first and second post each include a first and second end with the second ends of the first and second post securely mounted at each proximal end of each first and second side bar respectively. Each first and second post extends upwardly from the carriage frame relative the ground. A first crossbar is securely attached to each first end of the first and second post to interconnect the first post with the second post and to provide for an arm rest surface. The plurality of wheels includes a first and second wheel rotatably mounted at the second ends of the first and second posts, respectively. The proximal ends of each of the first and second side bars further include a downwardly and rearwardly extending portion to stop the device when the walker device is pivoted back enabling the downwardly and rearwardly extending portions to frictionally engage the ground thereby preventing the…
