| Abstract: |
A walker apparatus is disclosed which includes a support structure which extends substantially from the ground to the underarms of the user and encloses the user. The support structure includes a number of horizontally disposed ring members which are vertically separated by a plurality of struts and are pivotally connected to a longitudinally extending axial member. The support structure also includes a locking mechanism which is disposed at the upper front of the support structure. The walker apparatus also includes hand grips or, alternatively, crutches which extend from the uppermost ring member to the floor.

What is claimed is:
1. A walker apparatus for assisting a person who has a walking disability to move about in a substantially erect posture and by means of that person's own strength, comprising:
- a support structure having a plurality of structural members interconnected to define a shape approximating a truncated cone, said support structure having a height which is vertically adjustable to extend from a region near the surface on which said support structure is placed to the underarms of said person using said walker, said structural members including:
- a plurality of horizontally disposed ring members, each having first and second curvilinear elements interfacing at joining means for providing pivotation about an axis common to all said ring members;
- a plurality of strut members interconnected between respective ones of said curvilinear elements of said ring members to concentrically orient and vertically separate said ring members thereby establishing a lowermost ring member and an uppermost ring member; and
- an axial member associated with said joining means of each ring member and extending from said lowermost ring member to said uppermost ring member longitudinally along the forward portion of said walker apparatus for providing said common axis; and
- means for aiding the stabilization and movement of said support structure, said means being connected to one of said structural members at said region near the surface on which said support structure is placed and extending from said structural member to said surface.
