Foot for medical mobility device
A foot for a medical mobility device includes an upper portion, a traction surface, and a cushion ring. The upper portion has an opening at a first end for receiving an end of a medical mobility device and an upper portion post extending from a second end away from the opening. The traction surface has a core element that includes a cylindrical post extending upwardly from the traction surface. The upper portion is secured atop the core element. The cylindrical post is adhered to the upper portion post thereby defining a space between the upper portion and the traction surface, and the cushion ring is positioned in the space.
1. A foot for a medical mobility device, comprising:
an upper portion, comprising an opening at a first end for receiving an end of a medical mobility device, and an upper portion post extending from a second end away from the opening, wherein the opening extends only partially through the upper portion;
a traction surface having a core element comprising a cylindrical post extending upwardly from the traction surface; and
a hollow cushion ring filled with a gas;
wherein:
the first end of the upper portion is spaced apart from the second end thereby defining a midsection, wherein the midsection does not contact the cushion ring;
the cylindrical post is adhered to the upper portion post thereby defining a space between the second end of the upper portion and the traction surface; and
the cushion ring is positioned in the space.
2. The foot of claim 1 , wherein an outer wall of each of the upper portion post and the cylindrical post is concave.
3. The foot of claim 2 , wherein each of the upper portion post and the cylindrical post extends partially through an opening in the cushion ring such that a convex inside wall of the cushion ring is adjacent the concave outer wall of the upper portion post and the cylindrical post.
4. The foot of claim 1 , wherein the cylindrical post is hollow.
5. The foot of claim 1 , further comprising a plate element positioned between the core element and the upper portion.
6. The foot of claim 1 , wherein the traction surface comprises a tread pattern configured to disperse water away from the foot thereby increasing traction of the foot against a ground surface.
7. The foot of claim 1 , wherein the opening comprises a plurality of ribs defined at least partially along a vertical length of the opening.
8. The foot of claim 1 , wherein the medical mobility device is a crutch, a walker, or a cane.
9. The foot of claim 1 , wherein the gas is air or nitrogen.
10. The foot of claim 1 , wherein the upper portion comprises plastic or rubber.
11. The foot of claim 10 , wherein the traction surface comprises rubber or polyurethane.
12. A cushion system for a medical mobility device, comprising:
an upper portion, comprising a top surface defining an opening, a base surface spaced apart from the top surface, and a mid-section defined between the top surface and the base surface;
a bottom portion, comprising a top surface and a base surface;
a post; and
an air-filled cushion secured between the upper portion and the bottom portion and around the post,
wherein:
at least a portion of the base surface of the upper portion rests atop at least a portion of the top surface of the bottom portion thereby defining the post;
the post has an arcuately-shaped outer wall thereby defining a ring-shaped area for receiving the air-filled cushion;
the air-filled cushion rests in the ring-shaped area; and
the air-filled cushion does not contact the mid-section of the upper portion.
13. The cushion system of claim 12 , wherein the post:
is defined within the bottom portion;
forms part of the bottom portion; or
is formed by a projection extending from the upper portion and a projection extending from the bottom portion.
14. The cushion system of claim 12 , wherein the cushion system is a foot.
15. The cushion system of claim 12 , wherein the medical mobility device is a crutch, a walker, or a cane.
16. The cushion system of claim 12 , wherein the base surface comprises a tread pattern configured to disperse water away from the foot thereby increasing traction of the foot against a ground surface.
17. A foot for a medical mobility device, comprising:
an upper portion, comprising an opening at a first end for receiving an end of a medical mobility device, and an upper portion post extending from a second end away from the opening, wherein the opening extends only partially through the upper portion;
a traction surface having a core element comprising a cylindrical post extending upwardly from the traction surface; and
a cushion ring;
wherein:
the first end of the upper portion is spaced apart from the second end thereby defining a midsection, wherein the midsection does not contact the cushion ring;
the cylindrical post is adhered to the upper portion post thereby defining a space between the second end of the upper portion and the traction surface;
the cushion ring is positioned in the space; and
the cushion ring comprises a foam.
18. The foot of claim 17 , wherein the medical mobility device is a crutch, a walker, or a cane.
19. The foot of claim 17 , wherein the traction surface comprises a tread pattern configured to disperse water away from the foot thereby increasing traction of the foot against a ground surface.
20. The foot of claim 17 , wherein an outer wall of each of the upper portion post and the cylindrical post is concave.
