  • Patent number: 10413026
    Abstract: A reacher attachment assembly of use with a cane. The attachment assembly attaches a reacher to a cane such that the reacher is stored out of the way of the tip of the cane so as not to interfere with the cane when the reacher is not in use, but allows the reacher to be slid into position for use so that the cane tip does not interfere with the reacher. The attachment assembly may comprise a distal mount securely attached to the cane and slidingly attached to the reacher, a spring mount securely attached to the reacher, and a spring between the distal mount and the spring mount, such that the spring retains the reacher out of the way when not needed but allows the reacher to be extended downward relative to the cane for use.
