Abstract
There is provided, in combination, a collapsible walker and a collapsible basket. The walker includes a pair of spaced-apart, operatively interconnected frame members. The frame members each have an upper end for placing one's hand and a lower end spaced-apart from the upper end. Ground-engaging wheels are rotatably mounted to the lower ends of the frame members. A folding mechanism allows the frame members to be brought together for folding the walker. The collapsible basket includes a pair of spaced-apart, rigid end members, each being connectable with a respective one of said frame members. A flexible basket member extends substantially about, extends between and is supported by the rigid end members. The end members are moveable towards each other and the basket member thereby folds to collapse the basket when folding the walker.
Claims15
In combination, a collapsible walker and a collapsible basket, the walker including a pair of spaced-apart outer frame members and a folding mechanism configured to allow the outer frame members to be brought together for folding the walker, the folding mechanism including a foldable inner frame member that extends between and connects to respective ones of the outer frame members, the inner frame member including a pair of interengaging teeth disposed between the outer frame members, the teeth being positioned to interengage in an over-the-center action in the extended mode of the folding mechanism, the collapsible basket including:
- a pair of spaced-apart, rigid end members, each being connectable with respective ones of said outer frame members;
- and
- a flexible basket member extending about, extending between and being supported by said rigid end members, the end members being moveable towards each other and the basket member thereby folding to collapse the basket when folding the walker.
In combination, a collapsible walker and a collapsible basket, the walker including a pair of spaced-apart, operatively interconnected outer frame members and a folding mechanism configured to allow the outer frame members to be brought together for folding the walker, the folding mechanism including a foldable inner frame member that extends between and connects to respective ones of the outer frame members, the inner frame member including a pair of interengaging teeth disposed between the outer frame members, the teeth being positioned to interengage in an over-the-center action in the extended mode of the folding mechanism, the collapsible basket including:
- a pair of spaced-apart end members, each having a respective rigid peripheral portion and being connectable with respective ones of said outer frame members;
- and
- a flexible basket member extending about, extending between and being supported by said rigid peripheral portions, the end members being moveable towards each other and the basket member thereby folding to collapse the basket when folding the walker.
In combination, a collapsible walker and a collapsible basket, the walker including a pair of spaced-apart, operatively interconnected outer frame members, the 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, and a folding mechanism for allowing the outer frame members to be brought together for folding the walker, the folding mechanism being configured to fold the walker laterally and including a foldable inner frame member that extends between and connects to respective ones of the outer frame members, the inner frame member including a pair of interengaging teeth disposed between the outer frame members, the teeth being positioned to interengage in an over-the-center action in the extended mode of the folding mechanism, the collapsible basket being configured to collapse laterally and including:
- a pair of spaced-apart, flat end members, each having a respective rigid peripheral portion and being connectable with respective one of said outer frame members, each of the end members having one from the group consisting of an insert and a connection bracket shaped to slidably receive the insert and each of the outer frame members having a corresponding other one from the group consisting of the insert and the connection bracket, the end members connecting to and being readily removable from the respective outer frame members thereby;
- and
- a basket member, the basket member being made of flexible material, the basket member having a top facing the upper ends of the outer frame members, the top having an opening thereon for inserting objects into the collapsible basket, the basket member having a bottom opposite the top that extends between the end members, and the basket member having two spaced-apart sides extending respectively from both the top and bottom and between the end members, the sides being made of netting, the basket member extending substantially about, extending between and being supported by said rigid peripheral portions, the end members being moveable towards each other and the basket member thereby folding to collapse the basket when folding the walker.
