US Patent 9808392 Multi-mode hands-free crutch

A crutch includes a base, one or more leg support members coupled to the base, and an axillary support member coupled to the base. The leg support members are configurable to at least partially the weight of a person through the person's leg. The axillary support member is configurable to extend under one of the user's arms to at least partially bear weight of the person. The axillary support member may be adjustable to reversibly transform the crutch between axillary support of the person and leg support of the person. The crutch can be selectively configured for use in a hands-free walking mode, an axillary support mode, a sitting mode, or a compact mode.
