Expandable police baton

Abstract

A multiple section telescoping police baton is disclosed. The baton has a locking mechanism which is activated upon twisting of one section relative to the other in order to prevent sliding motion of one section relative to the other.

What is claimed is:  
     
       1. A police baton comprising first, second and third sections, adapted to be drawn out from a telescoped relationship to an extended relationship, said first section supporting said second section, and said second section supporting said third section and first and second means supported respectively by said second and third sections which upon rotation of said sections relative to the section within which they are at least partially positioned in at least one direction can cause the second section to lock in said first section and said third section to lock in said second section whereby motion of said each section relative to another is inhibited. 
     
     
       2. The police baton according to claim  1  in which said first and second means comprises a cam which is off center mounted to said respective section. 
     
     
       3. The police baton according to claim  2  in which said first and second sections are hollow. 
     
     
       4. The police baton according to claim  3  in which said first and second means support bumper means which engage stopping means positioned on the first and second section when said baton is fully extended. 
     
     
       5. A police baton comprising first and second sections, at least said first section being hollow and supporting said second section for translational motion therein, means for preventing said second section from falling out of said first section, and means for locking said first and second sections together to inhibit translational motion, said means comprising a cam which is offset mounted to said second section so that rotation of one section with respect to the other can cause off center mounted cam to move in a direction to engage the interior of the hollow first section. 
     
     
       6. The police baton according to claim  5  in which first section has plug means for limiting the movement of said second section within said first section.
