Abstract
A walker device ( ) includes a frame assembly ( ), which supports the user during operation and carries the other assemblies discussed below. Left and right front wheel assemblies ( ) include a pivoting fork supporting a wheel, thereby allowing directional control over the walker during use. Left and right rear wheel assemblies ( ) are fixed-direction. A brake assembly ( ) allows the user to apply a frictional brake element to the both rear wheels, and prevents unwanted movement by the walker. A support sling assembly ( ) carries some or all of the user's weight. Left and right lift cylinder assemblies ( ), ( ) lift and lower the support sling assembly to the desired elevation during use. A compressed air assembly ( ) provides power to the lift cylinder assemblies. A valve assembly ( ) provides independent control over both lift cylinder assemblies, to provide extra help to one side, if needed.
