Abstract

A collapsible rolling cane adapted to assist an elderly or handicapped person in walking. The cane includes a front leg having a handle attached to its upper end at a height convenient to the user, a single front wheel being mounted on the lower end. A shorter tubular rear leg is pivotally connected at its upper end to the leaf of a first hinge joined to the front leg at a position below the upper end thereof. The lower end of the rear leg is joined to the midpoint of a transverse axle on either end of which a rear wheel is mounted. Bridging the legs is a foldable arm, one end of which is pivotally connected to the leaf of a second hinge joined to the front leg at a position above its lower end, the other end of the arm being pivotally connected through a longitudinal slot in the rear leg to a slide therein, whereby when the cane is collapsed to put it in an inactive state, the slide rides up the rear leg to fold the arm and position the front and rear legs in parallel relation, and when the cane is put in an active state, the slide rides down the rear leg to extend the arm and cause the front and rear legs to assume an acute angle and the front and rear wheels then engage the ground at the points of a triangle to render the rolling cane stable.
