摘要:
An attachment to a walker that automatically positions a slip resistant surface under the foot of the user. Side-by-side slip resistant surfaces are attached to a walker. A retraction mechanism biases each of the slip resistant surfaces towards the walker. Upon stepping on one of the slip resistant surfaces and advancing the walker the retraction mechanism is extended. When taking a step removing pressure from the slip resistant surface, the slip resistant surface moves towards the walker positioned for receiving the user's foot during another step. Secure footing is obtained on wet or slippery surfaces preventing falls. The attachment is easily folded and closed to be positioned out of the way or removed for storage.
