Abstract

An attachment to a mobility aid, such as a walker, wheeled walker or rollator, or wheelchair that automatically positions a slip resistant surface under the foot of the user. An attachment bracket is attached to sides of the mobility aid. A retracting slip resistant surface and cleat assembly is removably attached to each attachment bracket. A cleat head assembly has engaging and disengaging replaceable cleats that selectively engage and disengage a slippery surface. Secure footing is obtained on wet or slippery surfaces preventing falls.

Claims (51)

1. An attachment to a mobility aid for improving stability of a user on a slippery surface comprising:

a pair of attachment brackets, each one of said pair of attachment brackets adapted to attach to an opposing side of the mobility aid; and

a retracting slip resistant surface and cleat assembly having a pair of pads, said retracting slip resistant surface and cleat assembly removably attached to each one of said pair of attachment brackets, the pair of pads positioned to contact the slippery surface;

retraction means, attaching each of the pair of pads to said retracting slip resistant surface and cleat assembly, for alternately retracting each of the pair of pads as the mobility aid is moved forward;

cleat means, coupled to each of the pair of pads, for positioning cleats into engagement with the slippery surface when the user steps on each of the pair of pads and disengagement with the slippery surface when the user steps off of each of the pair of pads,

whereby each of the pair of pads provide a slip resistant surface being positioned for a user to step on providing secure footing.

2. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 1 wherein:

each of said pair of attachment brackets has an intermediate pivot.

3. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 1 wherein:

said retraction means comprises an elastic element.

4. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 1 wherein:

said retraction means comprises a spring.

5. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 4 wherein:

the spring is a torsion spring.

6. An attachment to a mobility aid for improving stability of a user on a slippery surface comprising:

a pair of attachment brackets, each one of said pair of attachment brackets adapted to attach to an opposing side of the mobility aid; and

a retracting slip resistant surface and cleat assembly removably attached to each one of said pair of attachment brackets, said retracting slip resistant surface and cleat assembly comprises:

a slide assembly;

a retracting unit attached to said slide assembly;

a cleat head;

a retractable cord attached between said retracting unit and said cleat head; and

a pad attached to said cleat head,

whereby each said pad provides a slip resistant surface being positioned for a user to step on providing secure footing.

7. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 6 wherein:

said cleat head comprises selectively engaging and disengaging cleats.

8. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 7 wherein:

said selectively engaging and disengaging cleats engage the slippery surface when the user steps on said pad and disengages the slippery surface when the user removes pressure from said pad.

9. An attachment to a mobility aid for improving stability of a user on a slippery surface comprising:

a pair of attachment brackets, each one of said pair of attachment brackets adapted to attach to an opposing side of the mobility aid;

a slide assembly removably attached to each one of said pair of attachment brackets;

a retracting unit attached to said slide assembly;

a cleat head attached to said slide assembly and said retracting unit;

a retractable cord attached between said retracting unit and said cleat head; and

a pad attached to said cleat head,

whereby each said pad provides a slip resistant surface being positioned for a user to step on providing secure footing.

10. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 9 wherein:

said cleat head comprises selectively engaging and disengaging replaceable cleats.

11. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 10 wherein:

said cleat head has an angled surface relative to the slippery surface holding the selectively engaging and disengaging replaceable cleats and a contact surface adapted to slide along the slippery surface, said cleat head attached to said slide assembly and said retracting unit, wherein said pad is linked to the angled surface so that when said pad is moved closer to the slippery surface the angled surface rotates the selectively engaging and disengaging replaceable cleats engaging the selectively engaging and disengaging replaceable cleats with the slippery surface and when said pad is moved further away from the slippery surface the selectively engaging and disengaging replaceable cleats disengage the slippery surface permitting the contact surface to move along the slippery surface.

12. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 9 further comprising:

a channel lock formed on each one of said pair of attachment brackets, whereby said slide assembly is capable of being locked onto a respective one of said pair of attachment brackets.

13. The attachment to a mobility aid for improving stability of a user on a slippery surface as in claim 9 wherein:

said retracting unit comprises a torsion spring.

14. An attachment to a mobility aid for improving stability of a user on a slippery surface comprising:

a pair of attachment brackets, each one of said pair of attachment brackets adapted to attach to an opposing side of the mobility aid;

a slide assembly removably attached to each one of said pair of attachment brackets, said slide assembly having an outer slide cover and plurality of nested extendable slides contained therein;

a retracting unit attached to said outer slide cover of said slide assembly;

a cleat head having an angled surface relative to the slippery surface with replaceable cleats and a contact surface adapted to slide along the slippery surface attached to said slide assembly and said retracting unit;

a retractable cord attached between said retracting unit and said cleat head; and

a non-slip pad pivotally linked to the angled surface of said cleat head, wherein when the non-slip pad is moved closer to the slippery surface the angled surface rotates engaging the replaceable cleats with the slippery surface and when said non-slip pad is moved further away from the slippery surface the replaceable cleats disengage the slippery surface permitting the contact surface to move along the slippery surface,

whereby each said non-slip pad provides a slip resistant surface is positioned for a user to step on providing secure footing.
