Abstract
A wrap around walking aid is configured to assist a human user in walking. The wrap around walking aid includes a first rear lower frame and a first front lower frame mechanically coupled to a first upper frame. A back rest is connected to the first rear lower frame. A second rear lower frame and a second front lower frame are mechanically coupled to a second upper frame. The second rear lower frame is further mechanically coupled to the back rest. At least one first fixed front wheel is mechanically coupled to both front lower frames. At least one first castor rear wheel is mechanically coupled to both rear lower frames. The wheels enable a turn radius while the human user is walking forward.

A walking aid that assists a user having first and second forearms, elbows, and hands in walking in an upright position, the walking aid comprising:
- a rear lower frame structure comprising first and second rear lower frame members;
- a front lower frame structure comprising first and second front lower frame members, the first front lower frame member coupled to the first rear lower frame member, the second front lower frame member coupled to the second rear lower frame member;
- a first front wheel coupled to the first front lower frame member;
- a second front wheel coupled to the second front lower frame member;
- a first rear wheel coupled to the first rear lower frame member;
- a second rear wheel coupled to the second rear lower frame member;
- an upper frame structure comprising a first upper frame member, a second upper frame member, a first forearm support coupled to the first upper frame member and comprising a first forearm support surface for supporting the first forearm of the user, a second forearm support coupled to the second upper frame member and comprising a second forearm support surface for supporting the second forearm of the user, a first handle coupled with the first upper frame member, and a second handle coupled with the second upper frame member, the first upper frame member being adjustably coupled to the first rear lower frame member along a first length of the first upper frame member, the second upper frame member being adjustably coupled to the second rear lower frame member along a second length of the second upper frame member;
- and
- a back rest coupled to the rear lower frame structure and extending between the first and second rear lower frame members, wherein the first and second forearm support surfaces are non-parallel with a horizontal plane so as to angle the first and second forearms of the user, respectively, upward from the elbows to the hands, wherein the first and second forearm supports are positioned between the first and second handles, respectively, and the back rest such that the back rest is behind the user when assisting the user in walking in the upright position.
