1. A collapsible walker for use as an aid in walking, said collapsible walker comprising:a frame generally having the shape of a triangular pyramid and including a main leg, a rear leg, and a side leg being pivotally interconnected proximate a vertex of said pyramid, wherein at least two of said main, rear, and side legs are collapsible onto the third of said legs when said frame is collapsed; a wheel assembly disposed at a ground-engaging position on at least two of said main, rear, and side legs; and a handle disposed at an upper end of said frame and adapted to be grasped by a user with one hand while walking to permit the user to support some portion of the user's weight on said frame while rolling said wheel assemblies along the ground. 2. The collapsible walker of claim 1, wherein said rear leg is pivotably connected to said main leg, and said side leg is pivotably connected to said rear leg.3. The collapsible walker of claim 1, said frame further including a collapsible strut operatively mounted between two of said main, rear, and side legs.4. The collapsible walker of claim 3, including a first collapsible strut operatively mounted at opposite ends thereof to each of said main leg and said rear leg and a second collapsible strut operatively mounted at opposite ends thereof to each of said rear leg and said side leg.5. The collapsible walker of claim 1, further comprising a brake mechanism adapted to selectively arrest rolling movement of a one of said wheel assemblies.6. The collapsible walker of claim 5, wherein said brake mechanism comprises a manually actuable lever disposed proximate said handle, an engagement member disposed adjacent said wheel assembly and adapted for movement between a first position unengaged with said wheel assembly and a second position in braking engagement with said wheel assembly, and a tension member extending between said lever and said engagement member for transferring motion of said lever to said engagement member for urging said engagement member into said second position.7. The collapsible walker of claim 1, wherein each wheel assembly comprises a single wheel.8. The collapsible walker of claim 1, wherein at least one of said wheel assemblies is castered.9. The collapsible walker of claim 1, wherein said frame is oriented such that said main and rear legs lie substantially in a common vertical plane and said side leg extends to one side or the other of said plane.10. A walking aid for assisting a user walking to one side of said aid and being selectively configurable in either a functional or a stowable state, said aid comprising:a frame having three frame members interconnected with one another proximate upper ends thereof, at least two of said frame members being interconnect so as to be moveable between (1) first positions extending away from each other toward lower ends thereof so that said frame is in a stable, weight supporting configuration when said aid is in the functional state, and (2) second positions in which the lower ends of said frame members are in close proximity to each other so that said frame is in a compact configuration when said aid is in the stowable state; a wheel assembly disposed on a lower end of at least one of said frame members; and a handle disposed on an upper end of said frame, said handle being constructed and arranged in relation to said frame to permit a user to grasp the handle with one hand and to walk while supporting at least a portion of the user's weight on the aid while rolling the frame on said wheel assembly with the aid positioned to one side of the user. 11. The walking aid of claim 10, wherein said frame comprises a main frame member, a rear frame member, and a side frame member and said rear frame member is pivotably connected to said main frame member, and said side frame member is pivotably connected to said rear frame member.12. The walking aid of claim 10, said frame further including a collapsible strut operatively mounted between two of said three frame members.13. The walking aid of claim 11, including a first collapsible strut operatively mounted at opposite ends thereof to each of said main frame member and said rear frame member and a second collapsible strut operatively mounted at opposite ends thereof to each of said rear leg member and said side frame member.14. The walking aid of claim 10, further comprising a brake mechanism adapted to selectively arrest rolling movement of a one of said wheel assemblies.15. The walking aid of claim 14, wherein said brake mechanism comprises a manually actuable lever disposed proximate said handle, an engagement member disposed adjacent said wheel assembly and adapted for movement between a first position unengaged with said wheel assembly and a second position in braking engagement with said wheel assembly, and a tension member extending between said lever and said engagement member for transferring motion of said lever to said engagement member for urging said engagement member into said second position.16. The walking aid of claim 10, wherein each wheel assembly comprises a single wheel.17. The walking aid of claim 10, wherein at least one of said wheel assemblies is castered.18. The walking aid of claim 10, wherein the height of said handle is adjustable.19. The walking aid of claim 10, wherein at least two of said three frame members are connected within said frame so as to be pivotable with respect to at least one other frame member.
