Abstract:
1. A collapsible walker apparatus, the apparatus comprising: a pair of spaced-apart outer frame members, each having an upper end for placing one's hand and a lower end spaced-apart from the upper end; ground-engaging wheels rotatably mounted to the lower ends of the outer frame members; a pair of spaced-apart inner frame members interposed between and pivotally connecting to the outer frame members, each of the inner frame members including a first part and a second part hingedly connected together, one of said inner frame members having a seat handle outwardly extending therefrom; and a pair of link members diagonally extending between and pivotally connecting to the inner frame members for operatively connecting together the inner frame members, the link members crossing with each other, each of the link members having a bend extending outwardly towards a respective adjacent one of said outer frame members, one of the link members connecting to the first part of a first of the inner frame members and the second part of a second of the inner frame members and another of the link members connecting to the second part of the first of the inner frame members and the first part of the second of the inner frame members, the link members having an extended mode for opening the inner frame members outwards and thereby spacing-apart the outer frame members, and a folded mode actuated via the seat handle for bringing the inner frame members together and thereby bringing together the outer frame members to collapse the walker apparatus.
