1. An adjustable length walking cane comprising:
a tubular body having a top end and bottom end, and a front side; a base portion at the bottom end; a spring-biased gripper arm at the base portion; a selectively actuated illumination source at the base portion; a handle portion at the top end; a selectively actuated illumination source attached to the front side at the top end; a power source connected to the front illumination source and the base illumination source; one or more controls connected to the power source to selectively actuate the front and base illumination sources independently; a double spool sprocket flywheel assembly mounted to the body and having a first spool and a second spool; a selectively actuated flywheel lock; electrical filament spooled around the first flywheel spool and connected to the power source and the base and front illumination sources such that the tension on the electrical filament is maintained by the flywheel regardless of the length to which the cane is adjusted; tension filament spooled around the second flywheel spool and connected to the gripper arm at the base portion such that the tension on the tension filament is maintained by the flywheel regardless of the length to which the cane is adjusted; a selectively actuated flywheel lock to selectively lock or release the tension cable around the second spool to open the gripper arm; and a gripper arm trigger connected to the gripper arm by the tension cable to selectively open and close the gripper arm. |
