Abstract
A compact and collapsible cane includes a handle, a tip, and at least two collapsible cane segments joining the handle to the tip. In some aspects, the cane segments are configurable in an unfolded configuration and a folded configuration, where, in the folded configuration, a flat or nesting surface of one of the cane segments abuts a corresponding flat or nesting surface of an adjacent cane segment. In various examples, the collapsible cane includes a hinge with two parallel pivot axes between the two collapsible cane segments. In some examples, the cane includes a connector system with a male connector and a female connector connected by a shock cord between the two collapsible cane segments.
