ABSTRACT:
An activity walker has three wheeled legs positioned about an adjustable trunk surround member. The trunk surround member is hinged to open and is curved to approximate a users oval-shaped midriff. An adjustable closure on the torso/trunk surround member compensates for users of various girths. A flexible sling support extends across the interior of the surround member from its rear portion to its front portion, with fixed rearward attachments and a releasable front attachment to the interior of the surround member. This sling support is shaped to pass between a user's legs and provides body/trunk support when the user is standing upright. A length of each leg may be adjustable. The lateral extension of each leg outwardly from the surround member may be adjustable to reconfigure the stance/footprint of the walker. A friction pin may be utilized to adjust the rolling rate of each wheel.
