Abstract
A walking assistance device is disclosed that includes a support member having a first end and a second end. Attached to the support member is a hand grip, and attached to the second end is a base member. The base member includes a rounded surface that is configured to rotatably pivot relative to a walking surface as a user walks. The base member may further include a foot portion that has a toe and a heel. The toe and the heel may be the same length, or alternatively they may have varying lengths. Additionally, a pad is optionally attached to the foot portion and may be configured with tread to engage the walking surface in a way that provides traction to the walking assistance device.
Claims19
A walking assistance device, comprising:
- a support member having a first end and a second end;
- a hand grip coupled to said support member at a location away from said second end;
- and
- a first base member coupled to said second end of said support member, said first base member being vertically aligned at least partially with said second end of said support member, wherein said first base member comprises a curved bottom surface having a constant radius of curvature;
- a second base member comprising a curved bottom surface having a constant radius of curvature, said second base member being laterally outwardly offset relative to said first base member, said second end of said support member, and a user of the walking assistance device;
- and
- an extension having opposing first and second ends, said first end of said extension being coupled to said support member adjacent said first base member and said second end of said extension being coupled to said second base member, wherein said extension extends laterally outwardly from said first base member to said second base member;
- wherein said first base member is coupled to at least one of said extension or said second end of said support member;
- and said first and second base members and said extension cooperate such that the walking assistance device provides both vertical support and horizontal support to a user via the support member and hand grip.
6 more elements
A walking assistance device, comprising:
- a support structure that has a first end and a second end;
- an underarm support that is coupled to said support structure proximate said first end of said support structure;
- a hand grip coupled to said support structure between said first end and said second end;
- and
- a base assembly coupled to said second end of said support structure, said base assembly being configured to rotate relative to a walking surface, and said base assembly comprising:
- at least first and second base members, said second base member being laterally outwardly offset relative to said first base member, said second end of the support member, and a user of the walking assistance device, wherein said first base member is at least partially vertically aligned with said second end of said support structure;
- and
- an extension member having a first end coupled to said support structure adjacent said first base member and a second end coupled to said second base member, wherein said extension member extends laterally outwardly from said first base member to said second base member;
- wherein each of the first and second base members comprises a curved bottom surface having a constant radius of curvature.
6 more elements
A base assembly for a walking assistance device, comprising:
- a first foot portion, said first foot portion including:
- a toe;
- a heel;
- and
- a bottom surface joining said toe and said heel, wherein said bottom surface is curved with a radius of curvature that permits said base member to rotatably pivot relative to a walking surface while maintaining substantially constant contact with said walking surface, at least over a range of such pivot, wherein said first foot portion is coupleable in vertical alignment with a lower end of a walking assistance device;
- a second foot portion, said second foot portion including a curved bottom surface;
- an extension having a first end configured to be coupled to the walking assistance device adjacent the lower end of the walking assistance device and a second end coupled to said second foot portion to position said second foot portion laterally outwardly away from said first foot portion, said extension extending between said first foot portion and said second foot portion;
- and
- a connection mechanism at said first end of said extension, said connection mechanism being configured to couple said extension to the walking assistance device adjacent the lower end of the walking assistance device, wherein the connection mechanism fixes said second foot portion laterally outwardly away from said first foot portion to prevent movement of the second foot towards the walking assistance device.
