Abstract
The invention is directed to an outdoor device, preferably a string trimmer, having a hinged pole for folding the string trimmer. The hinge has an easy to use lock that allows for repeated folding of the trimmer for easy transport and storage. The string trimmer has a battery at a rear end of the pole near the handle, and a motor at a front end on the cutting head. An electrical cable is run from the battery to the motor to provide power to the motor. The hinge provides a protective sheath around the cable to protect it from damage when the string trimmer is folded and the cable might otherwise be exposed. Additionally, the string trimmer includes a guard around the cutting head that contacts a battery housing to secure the string trimmer in a folded position.
