PROTOTYPEPURPOSE: To design a cane that can assist an individual with mobility disabilities with walking and provide assistance as the individual stands from a seated position. The cane prototype consists of three major components: 1) a prefabricated ratcheting device, 2) a slide rod, and 3) a pair of telescoping rods. The ratcheting device was taken from a caulk gun. It uses springs and small plates to form a trigger and a locking mechanism. The locking mechanism prevents the rod from sliding when it is not desired. The rod from the caulk gun was removed and replaced by a 40-inch-long slide rod. Two telescoping rods were attached to form the body of the cane. One of the telescoping rods was attached to the ratcheting device from the caulk gun using a caulk adhesive. The other telescoping rod was attached to the bottom of the slide rod with a pin. The cane can be set to its minimum height by first pushing down on the locking mechanism to unlock it. The ratcheting device can then be moved down the slide rod so that the telescoping rods are completely overlapping. At this height individuals can use the cane to help themselves stand up from a sitting position. Once a person is standing, the trigger can be pulled repeatedly, until the cane is at the maximum height. At the maximum height, the cane functions as a standard walking cane. The total weight of the cane is two pounds, which is comparable to the weight of other canes. TITLE: Actively Adjustable Cane to Assist Standing from a Sitting Position.
