  • Convertible walking aid
    Patent number: 7007704
    Abstract: A convertible cane assembly comprises a pair of canes which can be used separately by a cane user. The canes include connections for securing the canes in side-by-side relation to provide a single cane which can be used in a normal manner. An important feature of the connections is the ability to easily separate the canes. In the single cane version, loads are preferably transferred through the entire length of both canes, meaning that the connections do not have to carry substantial loads.
