Abstract

A self defense baton comprises a handle portion which includes a central portion and a housing member connected to one end of the central portion. A flashlight portion is connected to the other end of the central portion. At least one telescoping member is slidably disposed within the housing member. The telescoping member is spring loaded and retained within the housing member by a releasable latch. A ring is rotatably attached to the handle portion. To use, the handle portion is grasped with a finger of the grasping hand being inserted through the ring. The releasable latch is activated by the thumb of the grasping hand. A spring, disposed within the housing member, causes the telescoping member to slide out of the housing member thereby expanding the baton. The rotatably attached ring enables rapid manipulation of the baton without risking accidental loss of the baton during these manipulations. The ring may also double as a key ring without loss of maneuverability of the baton.
