A Self-Help Device for One-Handed Storage of a Folding Umbrella in Its Cover

Purpose: Individuals with limited use of one hand, such as those with hemiplegia, often struggle with handling umbrella. While automatic umbrellas can be opened and closed with one hand, storing them in their covers requires both hands. To address this issue, we developed a self-help device that stores the umbrella without rolling up the fabric. This study aims to assess user satisfaction with the device for practical use.
